Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

524
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.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...

Inflammatory Bowel Disease V: Surgical Management

259
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

228
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...

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

Esophageal Strictures-I: Introduction01:30

Esophageal Strictures-I: Introduction

322
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

Drugs for Treatment of Diarrhea-Predominant IBS01:17

Drugs for Treatment of Diarrhea-Predominant IBS

364
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

Summary
This summary is machine-generated.

Anterior resection (AR) can cause bowel dysfunction. Low anastomotic levels and prior loop-ileostomy closure are linked to increased risks of incontinence and clustering after AR surgery.

Area of Science:

  • Colorectal Surgery
  • Gastrointestinal Oncology
  • Surgical Outcomes Research

Background:

  • Anterior resection (AR) for rectal cancer can lead to multifactorial defecatory dysfunction.
  • Understanding risk factors is crucial for improving patient quality of life post-surgery.

Purpose of the Study:

  • To investigate if the colon segment used for anastomosis (sigmoid vs. descending) impacts bowel function after AR.
  • To identify other potential risk factors for bowel dysfunction following AR.

Main Methods:

  • Retrospective analysis of prospectively collected data from a regional registry (1996-2019).
  • Included 412 patients who underwent anterior resection for stage I-III rectal cancer.
  • Bowel function assessed one year post-AR or stoma reversal.

Main Results:

  • Common dysfunctions included clustering (57%), incontinence (29%), urgency (22%), and evacuatory dysfunction (16%).
  • Higher anastomotic levels correlated with reduced risk of incontinence and clustering.
  • Loop-ileostomy closure significantly increased risks of clustering, incontinence, and urgency compared to no ileostomy.

Conclusions:

  • The specific colon segment used for anastomosis did not significantly affect functional outcomes.
  • Low anastomotic level and prior diverting ileostomy closure are independent risk factors for adverse functional outcomes after AR.
