Study Notes
Johnson's Gastric Ulcer Classification
- Type I: Most common, along the lesser curvature near the incisura.
- Type II & III: Prepyloric and duodenal ulcers; associated with acid hypersecretion, responding well to PPIs or vagotomy.
- Type IV: High in the body, most prone to bleeding, often involving the left gastric artery.
- Type V: Diffuse, often linked to NSAID use.
Gastric Ulcer Characteristics and Clinical Features
- Pain worsens after eating.
- Perforation is the most frequent complication.
- Most implicated vessels in peptic ulcer bleeding: Gastroduodenal artery (for peptic ulcers), Left gastric artery (for gastric ulcers).
- Type I ulcers are managed through distal gastrectomy and reconstruction (Billroth I or II).
- Types II and III ulcers require distal gastrectomy, reconstruction, and PPIs/vagotomy due to hyperacidity.
Gastric Venous Supply and Metastasis
- Gastric veins follow the arterial pattern.
- The left gastric/coronary vein is a key route for liver metastasis.
Congenital Hypertrophic Pyloric Stenosis (CHPS)
- Also known as idiopathic hypertrophic pyloric stenosis.
- Thickened pyloric muscle causes gastric outlet obstruction (GOO), leading to vomiting.
- Most common in first-born males.
- Associated with Apert syndrome, Cornelia de Lange syndrome, decreased nitric oxide synthase levels, and early erythromycin use.
- Presents with projectile, non-bilious vomiting, usually starting after the first few weeks of life.
- Olive-shaped swelling and visible peristalsis (left to right) are palpable during feeding.
CHPS vs. Duodenal Atresia
- CHPS: Non-bilious projectile vomiting after a few weeks, common in first-born males, diagnosed via USG, treated with Ramstedt pyloromyotomy.
- Duodenal Atresia: Bilious vomiting from birth, associated with Down syndrome.
CHPS Evaluation
- USG: Measures pyloric channel thickness (>7mm) and length (>16mm).
- Contrast studies reveal a string sign, double tract sign, or mushroom sign.
- X-ray may show a single bubble sign.
CHPS Metabolic Abnormalities
- Vomiting leads to HCl loss, causing metabolic alkalosis (decreased H+ and Cl-).
- Compensatory mechanisms include increased urinary NaHCO3 excretion, decreased Na+, RAS activation, and aldosterone release.
- Paradoxical acidemia occurs later, while initial compensation involves K+ excretion.
- Hypokalemia, hyponatremia, hypochloremia, and metabolic alkalosis with paradoxical aciduria may be present.
Stomach Anatomy and Blood Supply
- Stomach regions: Cardia, fundus, body, antrum, pylorus.
- Arterial supply: Left gastric artery (from celiac axis), right gastric artery (from common hepatic artery), left gastroepiploic artery (from splenic artery), right gastroepiploic artery (from gastroduodenal artery). Extensive submucosal anastomoses ensure survival even if some vessels are ligated. The left gastric artery is involved in type IV ulcers and Mallory-Weiss tears.
Esophageal Cancer Staging (TMN)
- T status: Tis (high-grade dysplasia), T1 (lamina propria/muscularis mucosa/submucosa invasion), T2 (muscularis propria invasion), T3 (adventitia invasion), T4a (resectable adjacent structure invasion), T4b (unresectable adjacent structure invasion).
- N status: N0 (no metastasis), N1 (1-2 positive nodes), N2 (3-6 positive nodes), N3 (7+ positive nodes).
- M status: M0 (no distant metastasis), M1 (distant metastasis, most commonly liver).
Sievert Classification of Gastroesophageal Junction Tumors
- Type I and II categorized as esophageal cancer and Type III as gastric cancer. (Diagram needed here)
Esophageal Cancer Management
- T1a lesions (above submucosa): Endoscopic mucosal resection (EMR).
- T1b N0/Ta N0 lesions (submucosal invasion): Esophagectomy.
- T3 N1/T3/T4 lesions: Neoadjuvant chemotherapy and radiotherapy.
- Clinical esophageal tumors: Definitive chemoradiotherapy.
Esophagectomy Principles and Types
- Resection margins: Proximal (10cm), distal (5cm). Long margins needed to prevent recurrence.
- R0 resection (no microscopic disease), R1 (microscopic disease remaining), and R2 (gross disease remaining).
- Esophagectomy types: Transhiatal (Orringer), Ivor Lewis, McKeown's; each varying significantly in incision locations (neck, abdomen, thorax) and anastomosis site. (Table comparing different esophagectomy techniques provided in source material).
- Minimum 15 lymph nodes should be removed. Stomach is the most common replacement for the esophagus because of its blood supply. Colon or jejunum used if the stomach is involved.
Esophagectomy Complications
- Atelectasis, pneumonia, anastomotic leak (neck anastomosis more dangerous than thoracic), recurrent laryngeal nerve (RLN) injury, chylothorax (injury to thoracic duct, causing turbid fluid in drain).
Chemotherapy and Radiotherapy in Esophageal Cancer
- Combined chemoradiation improves outcomes. Chemo acts as a radiosensitizer.
- Drugs: Gemcitabine, cisplatin, 5-FU.
Self-Expanding Metallic Stents (SEMS)
- Used for malignant tracheo-esophageal fistulas.
- Presentation: Cough, pneumonia.
- Complications: Stent migration, bleeding, tumor regrowth.
- Prognostic factor: Tumor depth.
- Follow-up with endoscopy at 3-6 months.
Benign Esophageal Tumors
- Leiomyoma: Most common benign esophageal tumor, found in mid-distal esophagus, male-to-female ratio 2:1, usually asymptomatic, large tumors cause dysphagia, barium swallow shows a "punched-out appearance". Managed by enucleation or STER (submucosal tunneling and endoscopic resection).
Peptic Ulcer Complications: Bleeding
- Most common complication.
- Posterior ulcers more often involved. Gastroduodenal artery commonly implicated. Leading cause of upper GI hemorrhage.
- Management: Endoscopic hemostasis, H. pylori eradication. Re-bleeding may require repeat endoscopy, surgery (vessel ligation), or coagulation via adrenaline injection.
Peptic Ulcer Complications: Perforation
- Anterior ulcers (most common): Peritonitis, rebound tenderness, guarding, rigidity; X-ray shows gas under diaphragm. Managed with NPO, IV fluids, IV antibiotics (aerobic and anaerobic coverage), analgesics; followed by omental or Graham's patch repair.
- Posterior ulcers (rare): Perforate into retroperitoneum, may present as renal vein signs (gas under right kidney) or mimic appendicitis (Valentino syndrome). Kocherization (mobilization of duodenum) needed for visualization and repair.
CHPS Management
- Correct metabolic abnormalities first (normal saline with dextrose and KCl, Ringer's lactate).
- Ramstedt pyloromyotomy (open or laparoscopic): Feeding begins after 4-6 hours if uncomplicated, or after 24-48 hours if mucosal injury.
Peptic Ulcer Types and Characteristics
- Duodenal ulcer (most common): 90-95% associated with H. pylori, characterized by acid hypersecretion, pain relieved by food. Most common site: First part of duodenum (D1)
- Gastric ulcer: 60-65% association with H. pylori, Type I and III show increased acid production.
Esophageal Cancer Clinical Features and Investigations
- Progressive dysphagia (solids > liquids), weight loss, potential fistula formation with the trachea, and left recurrent laryngeal nerve (RLN) involvement (chronic cough, hoarseness).
- Definitive diagnosis: Endoscopic biopsy; overall staging: PET-CT; T&N staging: EUS; barium swallow showing "rat-tail/apple-core" appearance. (Images required here, including histologic layers).
