Procedure for Prolapse and Hemorrhoids (PPH), also known as circular stapled hemorrhoidectomy, is a common method of treating hemorrhoids due to its low risk of complications and minimal postoperative pain. Several complications have appeared alongside the rise of treated cases, however, and this has led to a progressive slowing of the clinical use of PPH in recent years. Anastomotic stenosis is one of the most common complications of PPH, but the greater amount of tissue removed and the speed with which it can heal make it the best choice for patients with severe prolapsed annular hemorrhoids or rectal mucosal prolapse. Therefore, academics continue to comprehensively study PPH to take advantage of annular resection and reduce complications. In this paper, we analyzed the causes, intraoperative warnings, and postoperative therapy of anastomotic stenosis induced by PPH, with an eye toward scientific application in the anorectal field, based on the experience of clinical applications.

Inflammatory Bowel Disease V: Surgical Management

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Endoscopic 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...

Assessment 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.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended.
