Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

148
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...

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...

Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

168
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:

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Endoscopic Procedures I: Esophagogastroduodenoscopy

319
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:

Summary

Gastric point-of-care ultrasound (GPOCUS) on postoperative day 1 can predict delayed bowel function after surgery. A full stomach identified by GPOCUS indicates a higher risk for complications and longer hospital stays.

Area of Science:

  • Gastroenterology
  • Surgical Innovation
  • Point-of-Care Diagnostics

Background:

  • Delayed bowel function (DBF) is a common postsurgical complication impacting recovery and hospital stay.
  • Gastric point-of-care ultrasound (GPOCUS) offers a non-invasive method to assess gastric volume.
  • Identifying a full stomach may help predict postoperative gastrointestinal issues.

Purpose of the Study:

  • To investigate if a full stomach identified by postoperative day 1 (POD1) GPOCUS predicts delayed bowel function.
  • To assess the correlation between POD1 GPOCUS findings and key postoperative outcomes.

Main Methods:

  • A prospective cohort study involving 50 colorectal surgery patients.
  • Blinded GPOCUS examinations on POD1 to assess gastric fullness.
  • Primary outcome: gastrointestinal-3 (GI-3) recovery, defined by diet tolerance and bowel function.

Main Results:

  • Eighteen patients had a full stomach on POD1 GPOCUS; 32 had an empty stomach.
  • Full stomachs were significantly associated with delayed GI-3 recovery (4 vs. 1 days) and longer length of stay (5 vs. 3 days).
  • Full-stomach patients experienced more emesis and nasogastric tube placement.

Conclusions:

  • POD1 GPOCUS is a valuable tool for predicting DBF and other postoperative complications.
  • Handheld GPOCUS can identify high-risk patients for preemptive interventions.
  • This technique shows promise for improving patient outcomes after abdominal surgery.
