Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

1.1K
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

2.0K
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

Inflammatory Bowel Disease V: Surgical Management

897
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:

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...

Summary

Laparoscopic ventral rectopexy corrected rectoanal intussusception anatomically, but did not consistently improve obstructed defecation or fecal incontinence symptoms in this small study.

Area of Science:

  • Colorectal Surgery
  • Minimally Invasive Procedures
  • Pelvic Floor Disorders

Background:

  • Laparoscopic ventral rectopexy is used for obstructed defecation and fecal incontinence in rectoanal intussusception.
  • Pelvic floor imaging outcomes after this procedure were previously unreported.

Purpose of the Study:

  • To assess the outcomes of laparoscopic ventral rectopexy for rectoanal intussusception.
  • To evaluate postoperative findings using evacuation proctography.

Main Methods:

  • Retrospective analysis of prospectively collected data from 26 patients.
  • Laparoscopic ventral rectopexy performed, with pre- and post-operative evacuation proctography.
  • Defecatory function assessed using Constipation Scoring System and Fecal Incontinence Severity Index.

Main Results:

  • Anatomical correction of rectoanal intussusception achieved in all patients.
  • Significant reduction in rectocele size and pelvic floor descent observed.
  • Symptomatic improvement in constipation (41%) and fecal incontinence (67%) noted, but not universally.

Conclusions:

  • Evacuation proctography confirms anatomical correction after laparoscopic ventral rectopexy for rectoanal intussusception.
  • Anatomical correction does not guarantee significant symptomatic improvement.
  • Preliminary findings suggest a need for further research with larger cohorts.
