Internal hernia associated with colostomy after laparoscopic abdominoperineal resection

Area of Science:

• Gastroenterology
• Surgical Oncology
• Abdominal Wall Surgery

Background:

• Laparoscopic abdominoperineal resection (APR) is a surgical procedure for rectal cancer.
• Colostomies are sometimes created as part of APR, involving bringing a portion of the colon through the abdominal wall.
• Internal hernias are potential complications following abdominal surgery.

Observation:

• A case of internal hernia developing after laparoscopic APR is presented.
• The small intestine herniated through an unusual space adjacent to the sigmoid colon stoma.
• This space was located between the sigmoid colon loop and the abdominal wall.

Findings:

• Internal hernias associated with colostomies are infrequent but significant complications.
• The herniated small intestine is at risk of ischemia.
• The sigmoid colon forming the stoma is also vulnerable to ischemia due to traction.

Implications:

• Early recognition and management of internal hernias post-colostomy are crucial.
• This complication highlights the importance of careful surgical technique and patient monitoring after laparoscopic APR.
• Understanding the anatomical risks can help prevent or mitigate this rare but severe outcome.
