Sigmoid volvulus with and without megacolon

Diseases of the Colon and Rectum

|October 1, 1982

Summary

This summary is machine-generated.

Sigmoid volvulus treatment varies by colon size. Flatus tube decompression and sigmoid resection are effective for standard cases, but acquired megacolon requires total colectomy for a cure.

Area of Science:

Gastroenterology
Colorectal Surgery

Background:

Sigmoid volvulus is a common cause of large bowel obstruction.
Acquired megacolon presents unique challenges in managing sigmoid volvulus.

Purpose of the Study:

To compare treatment outcomes for sigmoid volvulus with and without acquired megacolon.
To determine the optimal surgical approach for sigmoid volvulus in patients with acquired megacolon.

Main Methods:

Retrospective analysis of 66 consecutive sigmoid volvulus patients.
Categorization into groups with and without acquired megacolon.
Evaluation of treatment success including flatus tube decompression and sigmoid resection.

Main Results:

Flatus tube decompression and sigmoid resection were successful in patients without megacolon.

Related Experiment Videos

Patients with acquired megacolon had longer histories, more frequent bowel symptoms, and less success with conservative measures.

Sigmoidectomy alone was insufficient for patients with acquired megacolon, with persistent symptoms and recurrent volvulus observed.

Conclusions:

Acquired megacolon complicates sigmoid volvulus management.
Total colectomy appears necessary for definitive treatment of sigmoid volvulus in patients with acquired megacolon.
