Pyloric Obstruction

Pyloric Obstruction

Pyloric obstruction, also referred to as gastric outlet obstruction, is a condition characterized by narrowing or blockage at the pylorus—the muscular valve regulating the flow of stomach contents into the duodenum. When this passage becomes impaired, the stomach cannot effectively empty its contents into the small intestine. This disruption leads to a range of gastrointestinal symptoms, including early satiety, bloating, epigastric pain, postprandial nausea, persistent vomiting, and...

Endoscopic Procedures I: Esophagogastroduodenoscopy

Endoscopic Procedures I: Esophagogastroduodenoscopy

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Intestinal Obstruction I: Introduction

Intestinal Obstruction I: Introduction

Intestinal obstruction is a partial or complete blockage of the small or large intestine that disrupts the normal flow of intestinal contents through the lumen. This interruption impairs digestion, absorption, and fluid balance, and may lead to serious complications if not treated promptly.Mechanical ObstructionMechanical obstruction occurs when a physical blockage prevents intestinal contents from passing, arising from within the lumen or the bowel wall, or from external compression.Adhesions,...

Intestinal Obstruction II: Pathophysiology

Intestinal Obstruction II: Pathophysiology

Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...

Esophageal Strictures-II: Clinical Features and Management

Esophageal Strictures-II: Clinical Features and Management

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Summary

This summary is machine-generated.

Gastric obstruction occurred in 2.5% of patients after endoscopic submucosal dissection (ESD), particularly with resections exceeding 75% of the circumference. Early repeat endoscopy and cautious dilation are recommended for high-risk patients to manage stenosis.

Area of Science:

Gastroenterology
Endoscopy
Surgical Complications

Background:

Gastric endoscopic submucosal dissection (ESD) carries risks of bleeding and perforation.
Gastric obstruction is a less commonly reported complication following ESD.

Purpose of the Study:

To investigate the clinicopathological characteristics of gastric obstruction after gastric ESD.
To identify risk factors and treatment outcomes for post-ESD gastric obstruction.

Main Methods:

Retrospective review of 1878 patients undergoing gastric ESD.
Analysis of lesion location, resection extent, and post-operative complications.
Assessment of risk factors for gastric obstruction and evaluation of treatment strategies.

Main Results:

Gastric obstruction occurred in 2.5% of patients, with symptoms appearing a median of 24 days post-ESD.
Higher incidence observed in upper (4.7%) and lower (3.8%) stomach lesions compared to the middle (0.36%).
Resection of >75% of the circumference was associated with a 50% obstruction rate; 87% of obstructed patients had stenosis, often treated with endoscopic balloon dilation (EBD).

Conclusions:

Patients with extensive resections (>75% circumference) require consideration for early follow-up endoscopy after ESD.
Endoscopic balloon dilation for stenosis should be performed cautiously due to potential complications like perforation.
