Summary
Delayed postpolypectomy bleeding, a complication of colorectal cancer precursor removal, is linked to right colon location and sessile polyps. Prompt hemoclip treatment is effective for managing this bleeding risk.
Area of Science:
- Gastroenterology
- Endoscopy
- Colorectal Cancer Prevention
Background:
- Colonoscopic polypectomy is crucial for removing colorectal cancer precursors.
- Delayed postpolypectomy bleeding is a significant complication, occurring in 1-6% of cases.
- Effective management of delayed bleeding requires understanding risk factors and preventive strategies.
Purpose of the Study:
- To identify risk factors associated with delayed postpolypectomy bleeding.
- To analyze treatment methods for delayed postpolypectomy hemorrhage.
- To improve patient outcomes following colonoscopic polypectomy.
Main Methods:
- Retrospective review of 1,841 polypectomy patients from January 2007 to December 2008.
- Analysis of 18 cases with delayed hemorrhage for risk factors, pathology, and treatment.
- Data collection included patient demographics, polyp characteristics, bleeding onset, and interventions.
Main Results:
- Delayed bleeding occurred in 0.95% (18/1,841) of patients.
- Higher incidence observed in the right colon (61.1%) and with sessile polyps (55.6%).
- Average polyp size was 9.2 mm; bleeding occurred 1-5 days post-resection. Tubular adenoma was the most common histology (72.2%).
Conclusions:
- Right colon location and sessile polyp morphology are risk factors for delayed bleeding.
- Reducing risk factors and close observation are vital for high-risk patients.
- Hemoclip application demonstrated effective hemostasis for delayed postpolypectomy bleeding.

01:25Endoscopic Procedures II: Colonoscopy
The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:
01:26Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

01:28Esophageal Varices-II: Clinical Features and Management
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.

01:25Assessment of the Rectum and Anus
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...
