Drain-associated intestinal obstruction after laparoscopic gastric bypass

Area of Science:

• Bariatric Surgery
• Gastrointestinal Surgery
• Surgical Complications

Background:

• Laparoscopic Roux-en-Y gastric bypass (RYGBP) is a common bariatric procedure.
• Intestinal obstruction is a potential complication following abdominal surgery.
• Abdominal drainage catheters are sometimes used postoperatively.

Observation:

• A 42-year-old woman presented with nausea, vomiting, and small bowel dilation post-RYGBP.
• Imaging revealed a small bowel loop twisting around an abdominal drainage catheter.
• Symptoms resolved immediately upon catheter removal.

Findings:

• The abdominal drainage catheter was identified as the cause of a rare internal hernia leading to intestinal obstruction.
• Early detection and removal of the catheter were crucial for patient recovery.

Implications:

• Avoidance of abdominal drainage catheters after uncomplicated laparoscopic RYGBP may prevent rare but serious complications.
• This case highlights the importance of considering unusual causes of postoperative obstruction.
• Further research into optimal postoperative management strategies after RYGBP is warranted.
