Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

149
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...

Endoscopic Procedures I: Esophagogastroduodenoscopy

332
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:

Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

755
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Inflammatory Bowel Disease V: Surgical Management

192
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:

Summary
This summary is machine-generated.

Endoscopy during revisional bariatric surgery (RBS) does not increase 30-day complications. This finding mirrors results from primary bariatric procedures, indicating safety for concurrent esophagogastroduodenoscopy.

Area of Science:

  • Bariatric Surgery
  • Gastrointestinal Endoscopy
  • Surgical Outcomes Research

Background:

  • Endoscopy is common in primary bariatric surgery (Roux-en-Y gastric bypass, sleeve gastrectomy) without increasing complications.
  • The safety and impact of concurrent endoscopy during revisional bariatric surgery (RBS) remain less understood.

Purpose of the Study:

  • To determine if concurrent endoscopy during RBS is associated with increased 30-day postoperative complications.
  • To compare outcomes of RBS with and without concurrent esophagogastroduodenoscopy (EGD).

Main Methods:

  • Analysis of the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database (2005-2017).
  • 1:1 propensity score matching for patient comorbidities and demographics.
  • Comparison of 17 postoperative outcomes using McNemar's and paired t-tests (P < 0.05).

Main Results:

  • A total of 7249 RBS cases were analyzed; 2329 remained after propensity score matching.
  • Esophagogastroduodenoscopy (EGD) was performed in 16% (375) of matched RBS cases.
  • No significant differences in complication rates were observed between RBS with and without EGD.

Conclusions:

  • Concurrent endoscopy during revisional bariatric surgery (RBS) is not associated with increased 30-day postoperative complications.
  • Approximately one-sixth of RBS cases involve concurrent endoscopy, similar to primary bariatric procedures.
  • Findings support the safety of performing esophagogastroduodenoscopy during RBS.
