Summary
Internal hernias are rare causes of bowel obstruction. Multi-detector row computed tomography (MDCT) can help diagnose intramesosigmoid hernias, aiding in surgical planning.
Area of Science:
- Gastroenterology
- Radiology
- Surgical Anatomy
Background:
- Internal hernias, where abdominal organs protrude into abnormal spaces, are infrequent causes of bowel obstruction.
- Preoperative diagnosis of internal hernias, particularly intramesosigmoid hernias, presents a significant clinical challenge.
Observation:
- A rare case of a 47-year-old female presented with strangulated small bowel obstruction.
- The obstruction was caused by an intramesosigmoid hernia, a protrusion of the small intestine into the sigmoid mesentery.
Findings:
- Multi-detector row computed tomography (MDCT) was utilized for preoperative diagnosis.
- MDCT imaging revealed characteristic findings indicative of an intramesosigmoid hernia, facilitating accurate diagnosis.
Implications:
- This case underscores the critical role of MDCT in the preoperative diagnosis of rare internal hernias.
- Accurate MDCT diagnosis can improve surgical outcomes for patients with bowel obstruction due to intramesosigmoid hernias.

01:25Assessment 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.

01:26Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
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 solid...

01:19Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
