Esophageal & Gastric Cancer

Esophageal cancer High-yield Verified · Sep 2026

Esophageal cancer is a malignancy of the esophageal lining, mainly squamous cell carcinoma or adenocarcinoma; gastric cancer is a malignancy of the stomach, mainly intestinal- or diffuse-type adenocarcinoma.

Esophageal cancer narrows the swallowing tube: dysphagia starts with solids and moves to liquids. Gastric cancer hides behind indigestion and fullness after small meals until it has spread. The operations change how the upper gut empties. That is why esophagectomy patients stay upright after eating, gastrectomy patients can dump, and anyone missing stomach tissue can run low on vitamin B12.

What’s going wrong in the body

The normal physiology, where it fails, and why the body’s compensation backfires.

01 Two esophageal cancers with two different causes

"Esophageal cancer is classified into 2 main types based on histologic features: squamous cell carcinoma and adenocarcinoma. In recent decades, the incidence of esophageal squamous cell carcinoma has decreased. In contrast, esophageal adenocarcinoma has risen significantly in the United States, particularly in the distal esophagus and gastroesophageal junction, mainly due to the prevalence of Barrett's esophagus."

[ESO] Adenocarcinoma — reflux to Barrett to cancer. "Repeated exposure of the lower esophagus to stomach acid secondary to chronic GERD, which leads to the replacement of the normal squamous epithelium with metaplastic columnar epithelium (ie, Barrett esophagus). The metaplastic epithelium may progressively undergo dysplastic changes, classified as low-grade or high-grade dysplasia." "High-grade dysplasia can progress to invasive adenocarcinoma." NCI adds: "Obesity in combination with GERD may further increase the risk of adenocarcinoma of the esophagus."

[ESO] Squamous cell carcinoma — chronic irritation. "Chronic irritation and inflammation caused by smoking, alcohol consumption, hot beverages, and poor nutrition can damage the esophageal mucosa," leading to genetic changes that disrupt "normal cell cycle regulation." Alcohol matters for squamous cancer only: "Alcohol intake is not associated with adenocarcinoma."

Adenocarcinoma follows reflux-driven Barrett metaplasia and dysplasia; squamous cell carcinoma follows chronic irritation from smoking and alcohol. Both narrow the lumen and cause progressive dysphagia.

02 Gastric cancer — H. pylori and a long, silent march

[GAS] The H. pylori pathway. NCI: "Chronic infection of the mucosal layer of the stomach with H. pylori is a major risk factor for stomach cancer." "Although many people with chronic H. pylori infections do not have symptoms," some develop atrophic gastritis, which "leads to increasingly severe changes in the stomach lining and eventually to stomach cancer or gastric MALT lymphoma." StatPearls: "H pylori is the most common inciting factor for carcinogenesis," and "gastric ulcers, atrophic gastritis, and pernicious anemia, often precede the development of cancer." "Treatment of H. pylori infections reduces the risk of these types of stomach cancer."

Two histologic forms. "Gastric cancer primarily arises in 2 histologic forms: intestinal and diffuse-type cancers." "In diffuse-type cancers, no defined precancerous lesions have been identified." Location follows the cause: H. pylori raises the risk "in the lower and middle part of the stomach, while obesity and gastroesophageal reflux disease (GERD) increase the risk of cancer in the upper stomach" (NCI).

Why it is found late. "Often, gastric cancer is advanced at diagnosis due to the late onset of symptoms." "Early-stage disease constitutes only 10% to 20% of all gastric cancer cases diagnosed in the United States" (StatPearls). About 12% to 27% of gastric cancers carry HER2 amplification — the target for trastuzumab.

Chronic H. pylori infection drives atrophic gastritis, dysplasia and intestinal-type cancer; diffuse-type cancer has no known precursor, and both are usually found after spread.

03 What surgery changes — conduit, emptying, intrinsic factor

[ESOPH-SURG] The conduit cannot squeeze. After esophagectomy a gastric tube serves as the conduit. "The conduits will lose their peristalsis, and postoperative instructions would be concerned with delayed emptying or poor emptying, so staying upright after oral intake is critical for the patient to avoid aspiration events." The anastomosis can leak: "Leaks at the anastomosis between the esophagus and the gastric conduit can occur in 5% to 20% of cases, leading to mediastinitis, sepsis, and prolonged hospitalization."

[DUMP] Rapid emptying → dumping. "Dumping syndrome is a postprandial disorder caused by rapid gastric emptying or too large a quantity reaching the small intestine." Early dumping comes from "the rapid transit of hyperosmolar chyme from the stomach to the duodenum, causing fluid shifts from the vasculature into the small bowel." Late dumping is "hypoglycemia arising from a hyperinsulinemia response to hyperglycemia noted in the early dumping phase." It affects up to 40% after gastrectomy and about 27% after esophageal cancer surgery (StatPearls).

[GASTRECT] Lost acid and intrinsic factor → B12. Removing all or part of the stomach "can cause a complete or partial loss of cells that secrete hydrochloric acid and cells that secrete intrinsic factor," so "these procedures reduce the amount of vitamin B12, particularly food-bound vitamin B12, that the body absorbs" (NIH ODS). Because the body stores a lot of B12, "the symptoms of vitamin B12 deficiency can take several years to appear."

Esophagectomy leaves a conduit without peristalsis and an anastomosis that can leak; gastrectomy speeds emptying (dumping) and removes the intrinsic-factor cells (vitamin B12).

Causes & risk factors

Modifiable factors are teaching targets — the patient can act on them.

[ESO][SCC] Smoking and heavy alcohol use — "the main risk factors for esophageal SCC" with a diet low in fruits and vegetables; also achalasia, caustic injury, tylosis and Plummer-Vinson syndrome modifiable [ESO][ADENO] Long-standing GERD and Barrett esophagus — with smoking, high body mass index and a diet low in fruits and vegetables; "Alcohol intake is not associated with adenocarcinoma" modifiable [ESO] Medicines that relax the lower esophageal sphincter — "may increase the likelihood of developing GERD" (NCI) [GAS] Chronic H. pylori infection — "a major risk factor for stomach cancer"; treatment lowers the risk modifiable [GAS] Diet — high salt, salt-preserved, smoked or cured foods; low fruit and vegetables; "lack of refrigerated foods" modifiable [GAS] Smoking — raises risk and "makes treatment for H. pylori infection less effective" modifiable [GAS] Pernicious anemia and chronic atrophic gastritis — raise the risk of intestinal-type cancer "up to 6-fold" (StatPearls) [GAS] First-degree relative with stomach cancer; older age; male sex; rubber or coal industry work (NCI)

Signs & symptoms

Each finding tied to the mechanism that produces it — and the triage it calls for.

[ESO] Progressive dysphagia — solids first, then liquids Hold & notify
Why: "This difficulty in swallowing typically starts with solid foods and progresses to liquids as the tumor enlarges, narrowing the esophageal lumen."
Unintentional weight loss; cachexia; painful swallowing (odynophagia) Hold & notify
Why: Weight loss comes from "the reduced ability to eat and the increased metabolic demands of the growing tumor."
[ESO] Chest pain; hoarseness late
Why: Chest discomfort with mid or lower tumors; hoarseness when the tumor invades the recurrent laryngeal nerve — "often concerning for more advanced disease."
[GAS] Persistent indigestion, fullness or bloating after small meals (early satiety), nausea early
Why: StatPearls lists "a feeling of fullness or bloating after small meals"; the gastrectomy chapter names "early satiety" among common presentations.
Iron deficiency anemia; black or bloody stools Hold & notify
Why: Chronic blood loss from the tumor; StatPearls: "Alarm symptoms that require urgent evaluation with an upper endoscopy include upper or lower gastrointestinal bleeding, weight loss, or dysphagia."
[GAS] Virchow node (left supraclavicular), periumbilical nodule, ascites, palpable mass late
Why: Signs of metastatic gastric cancer: "the Virchow node (ie, left supraclavicular adenopathy), Sister Mary Joseph node (ie, periumbilical nodule)," peritoneal spread with ascites.
Coughing or choking with swallowing, new fever or shortness of breath Report immediately
Why: Aspiration from obstruction or poor motility can cause "aspiration pneumonia, the formation of lung abscesses, or acute respiratory distress syndrome (ARDS), all of which are potentially life-threatening and require prompt medical attention."
[ESOPH-SURG] Red or inflamed neck incision, or fever from about post-op day 3 Hold & notify
Why: StatPearls: these "indicate a leak until proven otherwise." Cervical leaks "tend to be minor"; a water-soluble contrast study is indicated.
[ESOPH-SURG] Signs of sepsis after esophagectomy (possible thoracic anastomotic leak) Report immediately
Why: Possible thoracic anastomotic leak: "Thoracic leaks, on the other hand, are life-threatening and demand operative exploration"; leaks lead to "mediastinitis, sepsis."
[GASTRECT] Acute abdominal pain, nausea or vomiting after gastrectomy Hold & notify
Why: Can signal leak, obstruction, duodenal stump blowout or bleeding; nurses should "contact surgical services promptly."
[DUMP] Within an hour of eating: bloating, cramping, diarrhea, flushing, palpitations, sweating, faintness Expected
Why: Early dumping — fluid shift into the small bowel after rapid emptying. Managed with diet (StatPearls).
[DUMP] 1–3 hours after eating: shakiness, sweating, hunger, confusion, weakness Hold & notify
Why: Late dumping — reactive hypoglycemia. Repeated episodes "may impair cognitive function, increase the risk of falls."

Diagnostics

Test In this disorder Normal
Upper endoscopy with biopsy "Endoscopy is the diagnostic test of choice, allowing for visual inspection, tissue sampling, and resection of early tumors." Suspicious gastric ulcers are biopsied multiple times — sensitivity rises "from approximately 70% with a single biopsy to 98% with 7 biopsies." Visualizes and samples the tumor; can resect early lesions —
Endoscopic ultrasound (EUS) "EUS is instrumental in determining the T stage of the tumor and evaluating the perigastric lymph nodes." Depth of invasion (T stage) and nearby lymph nodes StatPearls, citing NCCN —
HER2 testing (gastric) "Patients eligible for chemotherapy should be tested for HER2 overexpression." HER2-positive → eligible for trastuzumab with chemotherapy —
Barrett esophagus surveillance "Patients with Barrett esophagus are typically monitored through upper endoscopy and biopsy to check for dysplasia." Dysplastic Barrett may be treated with radiofrequency ablation (NCI); superficial lesions may be removed endoscopically. Endoscopy and biopsy for dysplasia —
CBC From chronic blood loss from the tumor (StatPearls). Iron deficiency anemia —
[ESOPH-SURG] Water-soluble contrast study "All patients should have a contrast study anywhere from 3 to 7 days postoperatively to rule out any type of leak. If the study is normal, then oral intake can commence." Any sign of a leak also triggers the study. No leak before oral intake —
[GASTRECT] Vitamin B12 status Symptoms of deficiency — fatigue, neurological changes, megaloblastic anemia, glossitis — "can take several years to appear" (NIH ODS). Absorption is reduced after all or part of the stomach is removed (NIH ODS) —
Stage and survival (SEER, 5-year relative) Esophageal and stomach cancers are most frequently diagnosed at ages 65–74. StatPearls surgical series report different, stage-by-stage figures — do not merge them. Esophagus 22.2% overall (localized 48.6% · regional 29.1% · distant 5.3%); stomach 39.8% overall (localized 78.1% · regional 39.0% · distant 8.1%) NCI SEER (2016–2022) —

Complications

Black-box warning — most severe: ■ [ESOPH-SURG] Thoracic anastomotic leak Report immediately
"Thoracic leaks, on the other hand, are life-threatening and demand operative exploration." Leaks lead to "mediastinitis, sepsis, and prolonged hospitalization."
Cervical leaks "tend to be minor" and can be managed by opening the neck wound. "Cervical incisions that become red or inflamed or fevers starting about three days postoperatively indicate a leak until proven otherwise." Management ranges from antibiotics, drainage and nothing by mouth to surgical repair.
Black-box warning — most severe: ■ [ESO] Aspiration and tracheoesophageal fistula Report immediately
Aspiration can cause pneumonia, lung abscess or ARDS — "all of which are potentially life-threatening and require prompt medical attention."
Tumor invasion can create "tracheoesophageal or bronchoesophageal fistulae, leading to recurrent aspiration pneumonia, lung abscesses, or sepsis." After esophagectomy, the conduit "will lose their peristalsis," so upright positioning after eating prevents aspiration.
Warning: Bleeding, obstruction, perforation Hold & notify
Gastric tumor complications "include bleeding, obstruction, perforation, and fistulization to surrounding organs." In the esophagus, "complete obstruction can occur, necessitating nutritional support through feeding tubes or parenteral nutrition."
GI bleeding is an alarm symptom that requires urgent endoscopic evaluation (StatPearls).
Warning: [ESOPH-SURG] Pulmonary complications, chylothorax, hoarseness, stricture Hold & notify
"Atelectasis, pneumonia, and acute respiratory distress syndrome (ARDS) are common due to the proximity of the surgery to the lungs and the potential for aspiration."
Thoracic duct injury can cause a chyle leak (drainage, nothing by mouth or a low-fat diet, sometimes octreotide). Recurrent laryngeal nerve injury "can cause vocal cord paralysis and hoarseness." Anastomotic strictures cause dysphagia and are treated with endoscopic dilation. Cardiac arrhythmias are also a named complication.
Warning: [GASTRECT] Early post-gastrectomy complications Hold & notify
"These complications include anastomotic leak, bowel obstruction, postoperative ileus, duodenal stump blowout, delayed gastric emptying, surgical site infection, and intraabdominal infection."
Afferent loop syndrome (after Billroth II): "immediate postprandial pain and cramping, followed by vomiting that completely relieves symptoms"; detecting it early matters because of "its potential to lead to a duodenal stump leak."
Caution: [DUMP] Dumping syndrome Hold & notify
"In patients undergoing gastrectomy, dumping syndrome occurs in up to 40% of patients"; after esophageal cancer surgery the pooled prevalence is about 27% (StatPearls).
"Carbohydrate-rich meals often intensify both early and late manifestations." "Profound postprandial fatigue and the frequent need to lie down after eating" are clues. Late dumping can cause severe hypoglycemia. The gastrectomy chapter gives different timings (early within 30 minutes, late 2 to 4 hours) — the page uses the dedicated dumping chapter.
Caution: Malnutrition and vitamin B12 deficiency Hold & notify
"Dysphagia, anorexia, and cachexia can lead to profound malnutrition. This malnutrition can weaken the immune system, impair wound healing, and reduce the patient's ability to tolerate ongoing cancer treatments."
Long-term: "nutritional deficiencies due to the altered anatomy." Gastric surgery reduces B12 absorption; malabsorption of fat-soluble vitamins "can be associated with loss of duodenal continuity."

Medications for this condition

Why each class is prescribed here — every card links to its full pharmacology page.

Antineoplastic / Chemotherapy Overview First-line High-alert
Oncology

[ESO] Locally advanced disease (T3–T4 or node-positive): "neoadjuvant chemoradiotherapy followed by surgery is commonly recommended." Metastatic disease aims at "symptom palliation, improved quality of life, and prolonged survival." Pembrolizumab is listed for selected advanced tumors (StatPearls, citing NCCN). [GAS] "Patient outcomes improve with perioperative chemotherapy." HER2-positive: "trastuzumab with chemotherapy is the standard for HER2-positive cancers." Advanced gastric cancer therapy is palliative — "to alleviate symptoms, enhance quality of life, and modestly extend survival."
Antiemetics
Digestive / GI · ondansetron

Chemotherapy nausea and vomiting. "Gastrointestinal toxicities, which are common with chemotherapy, necessitate a comprehensive approach to symptom management. This includes using antiemetics to control nausea and vomiting."
Proton Pump Inhibitors
Digestive / GI · omeprazole

GERD control and a drug interaction. Patients with GERD manage symptoms with lifestyle changes "and medication (eg, proton pump inhibitors) as needed." Interaction: "Patients on oral capecitabine should not take proton pump inhibitors due to inferior absorption on less acid gastric pH."
Vitamin B12 & Folate
Hematologic · cyanocobalamin

[GASTRECT] Vitamin B12 after gastric resection. Loss of acid- and intrinsic-factor-secreting cells means "these procedures reduce the amount of vitamin B12, particularly food-bound vitamin B12, that the body absorbs" (NIH ODS). Deficiency can take years to appear. The sources give no route or dose for cancer gastrectomy.

Beyond medications

  • [ESO] Surgery — thoracic cancers get esophagectomy with lymph node dissection and "jejunostomy feeding tube placement"; transhiatal and transthoracic (Ivor-Lewis) approaches are used. Superficial lesions "may be candidates for endoscopic resection."
  • [GAS] Gastrectomy — "Gastrectomy remains the mainstay of curative treatment, with the extent of gastric resection tailored to tumor location and size," with "A comprehensive lymphadenectomy." Endoscopic resection of early lesions has 5-year survival of 84% to 96% (StatPearls).
  • Palliation — esophageal stent and radiation "particularly in scenarios such as dysphagia or bleeding."
  • Feeding tubes — before esophagectomy, "it is crucial to avoid placing gastric tubes before surgery"; "Jejunostomy tubes are often preferred for long-term nutritional support." After gastrectomy, a feeding jejunostomy is common "particularly for patients with risk factors for esophagogastric leak or preoperative weight loss."
  • [ESOPH-SURG] Recovery — ICU for the first 24 to 48 hours; epidural or IV analgesia; prophylactic antibiotics; mechanical and drug DVT prevention; "incentive spirometry, deep breathing exercises, and early ambulation"; contrast study, then "a clear liquid diet, gradually advancing to a soft diet as tolerated"; swallowing exercises and speech therapy for hoarseness.
  • [DUMP] Diet first-line — smaller meals; "Postponing fluid intake at least 30 minutes after meals"; "Elimination of rapidly absorbable carbohydrates"; foods rich in fiber and protein; eat slowly and chew well; lying down for 30 minutes after meals "to reduce symptoms of hypovolemia." If diet fails, somatostatin analogs or acarbose may be used (StatPearls).
  • Radiation effects — esophagitis, mucositis and skin reactions during treatment; later strictures, perforation or fistula.
  • Prevention — avoiding tobacco and alcohol lowers squamous cancer risk; "Smokers who stop smoking lower their risk of having stomach cancer over time"; treat H. pylori; manage GERD.

Nursing considerations

The RN-specific layer — each action paired with the reason it matters.

Assessment
Ask how swallowing has changed (solids → liquids) and track weight and intake.
Why: Progressive dysphagia and unintentional weight loss are the main esophageal cancer clues; malnutrition impairs healing and treatment tolerance.
Watch for coughing or choking with meals, new fever or dyspnea.
Why: Aspiration pneumonia, lung abscess and ARDS are "potentially life-threatening and require prompt medical attention."
After esophagectomy: monitor vital signs, respiratory status and fluid balance closely; inspect the neck incision and track temperature from post-op day 3.
Why: Early detection of complications in the ICU phase; a red neck incision or fever from about day 3 means "a leak until proven otherwise."
Listen for new hoarseness after esophagectomy.
Why: Recurrent laryngeal nerve injury "can cause vocal cord paralysis and hoarseness"; speech therapy may be needed.
After gastrectomy: assess for acute abdominal pain, nausea or vomiting, and pain after eating that is relieved by vomiting.
Why: StatPearls: prompt identification lets nurses "contact surgical services promptly"; the last pattern suggests afferent loop syndrome.
Ask about symptoms within an hour of eating and shakiness, sweating or confusion 1–3 hours after.
Why: Early and late dumping; repeated hypoglycemia increases fall risk.
Interventions
Keep the esophagectomy patient upright while eating and for at least 2 to 3 hours after; offer small, frequent meals.
Why: The conduit lacks peristalsis, and "staying upright after oral intake is critical for the patient to avoid aspiration events."
Hold oral intake until the contrast study is normal, then advance from clear liquids to soft diet as ordered.
Why: "If the study is normal, then oral intake can commence."
Escalate at once for signs of sepsis after esophagectomy — a possible thoracic anastomotic leak.
Why: "Thoracic leaks, on the other hand, are life-threatening and demand operative exploration."
Promote incentive spirometry, deep breathing and early ambulation; give DVT prophylaxis and analgesia as ordered.
Why: Atelectasis and pneumonia are common after esophagectomy; these measures are part of standard recovery.
Give jejunostomy feedings as ordered when oral intake is not enough.
Why: Enteral nutrition "via a jejunostomy tube is often provided to support healing and recovery."
Report black or bloody stools, vomiting blood, or worsening dysphagia urgently.
Why: GI bleeding and dysphagia are alarm symptoms that "require urgent evaluation with an upper endoscopy."
Patient and family teaching
Dumping diet: smaller meals, fluids at least 30 minutes after meals, no rapidly absorbed sugars, more fiber and protein, eat slowly and chew well, and lie down for 30 minutes after meals (StatPearls dumping-syndrome list).
Why: StatPearls dumping-syndrome first-line measures. After esophagectomy, the upright-after-eating rule still applies to prevent aspiration.
For late dumping, pair carbohydrates with protein or fat, avoid high-glycemic foods, and report persistent or worsening symptoms.
Why: This prevents reactive hypoglycemia and complications "such as malnutrition, weight loss, or severe hypoglycemia."
Know that stomach surgery reduces vitamin B12 absorption, and report fatigue, neurological changes or a sore, inflamed tongue — even years later.
Why: Gastric surgery reduces B12 absorption, and deficiency symptoms "can take several years to appear."
If on capecitabine, do not take proton pump inhibitors.
Why: PPIs reduce capecitabine absorption (StatPearls).
Stop smoking and alcohol; get H. pylori treated; manage reflux (smaller meals, avoid trigger foods, raise the head of the bed).
Why: These are the modifiable risks for squamous, adenocarcinoma and gastric cancers.

How a real nurse thinks

The clinical-judgment loop, worked for a typical presentation — reasoning, not reference.

  1. 1
    Recognize cues

    Fever and a red, inflamed neck incision on post-op day 4, mild tachycardia, and a request for oral fluids before the contrast study. Hoarseness since surgery is noted.

  2. 2
    Analyze cues

    "Cervical incisions that become red or inflamed or fevers starting about three days postoperatively indicate a leak until proven otherwise." Cervical leaks "tend to be minor," but a thoracic leak is "life-threatening." The red, inflamed neck incision points to the cervical anastomosis. Hoarseness fits recurrent laryngeal nerve injury.

  3. 3
    Prioritize

    Suspected anastomotic leak comes first: keep him nothing by mouth and get the surgeon to evaluate. The hoarseness is reported but not urgent.

  4. 4
    Generate solutions

    Do not give water; continue jejunostomy feeding as ordered; notify the surgeon now; anticipate a water-soluble contrast study and wound opening or drainage if a cervical leak is confirmed; watch closely for sepsis signs.

  5. 5
    Take action

    SBAR: 67-year-old POD 4 transhiatal esophagectomy; new fever 38.2 °C, HR 102, red and warm left neck incision. Concern for cervical anastomotic leak. He is NPO with feeds via jejunostomy. Request surgical evaluation and orders for a contrast study.

  6. 6
    Evaluate

    Recheck temperature, heart rate, breathing and pain frequently; escalate at once if signs of sepsis develop — a leak can lead to "mediastinitis, sepsis," and a thoracic leak is "life-threatening."

Scenario — you’re the nurse

Work each question before revealing the answer. Rationales explain the wrong options too.

Surgical step-down unit · post-op day 4 after transhiatal esophagectomy, 1000

A 67-year-old man with esophageal adenocarcinoma arising in Barrett esophagus had neoadjuvant chemoradiotherapy and then a transhiatal esophagectomy with a gastric conduit, a cervical anastomosis and a feeding jejunostomy. The contrast study is scheduled for tomorrow.

0600 — T 38.2 °C (first fever since surgery); HR 102; BP 128/76; RR 20; SpO2 95% on 2 L
Neck incision — new redness and warmth along the left cervical wound
Jejunostomy — tube feeding running at goal; abdomen soft
Patient — alert, voice slightly hoarse since surgery; asks for a drink of water
Chest — clear bilaterally; no chest pain
Q1 Multiple choice
Which finding on post-op day 4 after esophagectomy should the nurse treat as a possible anastomotic leak?
  1. A. Mild incisional pain controlled by analgesia
  2. B. A red, inflamed neck incision with a new fever
  3. C. Fullness after a small meal
  4. D. Tube feeding running at goal rate
Reveal answer & rationale
Answer: B
"Cervical incisions that become red or inflamed or fevers starting about three days postoperatively indicate a leak until proven otherwise" (B). Controlled incisional pain (A) is expected. Fullness after small meals (C) reflects delayed conduit emptying, which is common. Feeding at goal (D) is the plan working.
Q2 Select all that apply
Which instructions help prevent aspiration after esophagectomy? Select all that apply.
  1. A. Stay upright while eating
  2. B. Stay upright for at least 2 to 3 hours after eating
  3. C. Eat small, frequent meals when oral intake begins
  4. D. Lie flat for 30 minutes after every meal
  5. E. Start oral intake only after a normal contrast study
Reveal answer & rationale
Answer: A, B, C, E
The conduit loses peristalsis, so patients should "be upright eating and after oral intake for 2 to 3 hours minimum" (A, B), and "Small frequent meals are better than larger meals" (C). Oral intake starts once the contrast study is normal (E). Lying flat after meals (D) contradicts the upright rule that prevents aspiration after esophagectomy; lying down appears only in the dumping-syndrome diet list.
Q3 Multiple choice
A patient 3 months after partial gastrectomy reports shakiness, sweating and confusion about 2 hours after a sugary lunch. What is the best explanation?
  1. A. Early dumping from fluid shifts
  2. B. Late dumping with reactive hypoglycemia
  3. C. Anastomotic leak
  4. D. Vitamin B12 deficiency
Reveal answer & rationale
Answer: B
Late dumping occurs "within 1 to 3 hours of meal intake and are characterized by hypoglycemia" from an insulin surge (B). Early dumping (A) comes within an hour and is driven by fluid shifts. A leak (C) is an early post-op problem with pain and fever. B12 deficiency (D) develops over years with fatigue, neurological changes and anemia.
Q4 Multiple choice
Which diet teaching is correct for a patient with dumping syndrome after gastrectomy?
  1. A. Drink plenty of fluids with each meal
  2. B. Choose simple sugars for quick energy
  3. C. Take fluids at least 30 minutes after meals and eat smaller meals rich in fiber and protein
  4. D. Eat three large meals a day to keep the stomach remnant stretched
Reveal answer & rationale
Answer: C
StatPearls first-line measures include "Postponing fluid intake at least 30 minutes after meals," smaller meals and "Consuming foods rich in fiber and protein" (C). Fluids with meals (A) speed emptying. "Elimination of rapidly absorbable carbohydrates" helps late dumping (B). Larger meals (D) worsen dumping.
Q5 Multiple choice
A patient with long-standing reflux asks which esophageal cancer his reflux raises the risk of. What is the nurse's best answer?
  1. A. Squamous cell carcinoma, mainly through alcohol
  2. B. Adenocarcinoma, through Barrett esophagus
  3. C. Gastric MALT lymphoma
  4. D. None — reflux does not affect cancer risk
Reveal answer & rationale
Answer: B
Chronic GERD replaces the lower esophageal lining with metaplastic columnar cells (Barrett esophagus), which can progress through dysplasia to adenocarcinoma (B). Squamous cell carcinoma is linked to smoking and alcohol, and "Alcohol intake is not associated with adenocarcinoma" (A). MALT lymphoma (C) is linked to H. pylori in the stomach. Reflux clearly raises adenocarcinoma risk (D).

Common questions

What causes esophageal & gastric cancer?
Common causes and risk factors include [eso][scc] smoking and heavy alcohol use — "the main risk factors for esophageal scc" with a diet low in fruits and vegetables; also achalasia, caustic injury, tylosis and plummer-vinson syndrome, [eso][adeno] long-standing gerd and barrett esophagus — with smoking, high body mass index and a diet low in fruits and vegetables; "alcohol intake is not associated with adenocarcinoma", [eso] medicines that relax the lower esophageal sphincter — "may increase the likelihood of developing gerd" (nci), [gas] chronic h. pylori infection — "a major risk factor for stomach cancer"; treatment lowers the risk, [gas] diet — high salt, salt-preserved, smoked or cured foods; low fruit and vegetables; "lack of refrigerated foods", and others.
Why does esophageal cancer cause trouble with solids before liquids?
The tumor narrows the lumen gradually. "This difficulty in swallowing typically starts with solid foods and progresses to liquids as the tumor enlarges, narrowing the esophageal lumen."
Does H. pylori cause esophageal cancer?
No. H. pylori is a major risk factor for stomach cancer (and gastric MALT lymphoma). Esophageal adenocarcinoma follows GERD and Barrett esophagus; squamous cell carcinoma follows smoking and alcohol.
Should a patient lie down or sit up after eating?
After esophagectomy, stay upright while eating and for at least 2 to 3 hours after, because "staying upright after oral intake is critical for the patient to avoid aspiration events" (StatPearls, transhiatal esophagectomy). Lying down for 30 minutes after meals "to reduce symptoms of hypovolemia" appears only in the StatPearls dumping-syndrome diet list; it is not an esophagectomy instruction — the upright rule is the one taught for esophagectomy patients.
Why can vitamin B12 run low years after stomach surgery?
Removing stomach tissue removes cells that secrete acid and intrinsic factor, so less B12 is absorbed, and because the body stores a lot, "the symptoms of vitamin B12 deficiency can take several years to appear" (NIH ODS).
What is the outlook?
SEER 5-year relative survival is 22.2% for esophageal cancer and 39.8% for stomach cancer, far higher when the cancer is localized (48.6% and 78.1%) than when it has spread (5.3% and 8.1%).
