Blind loop perforation after side-to-side ileocolonic anastomosis

Area of Science:

• Gastroenterology
• Surgical Complications

Background:

• Side-to-side ileocolonic anastomosis is a common surgical technique.
• Blind loop syndrome is a recognized, though not well-defined, complication.
• Ileal cul-de-sac dilation leads to stasis and bacterial overgrowth.

Observation:

• This study reports three cases of perforative blind loop syndrome.
• Patients presented a few years after right hemicolectomy with side-to-side ileocolonic anastomosis.
• Symptoms included acute abdomen, suggesting a serious complication.

Findings:

• Blind loop syndrome can lead to mucosal ulceration and full-thickness perforation.
• Bacterial overgrowth in the dilated ileal segment is the primary mechanism.
• The incidence and precise complication rates remain unclear.

Implications:

• Blind loop syndrome may be an underdiagnosed complication of digestive surgery.
• Consideration of blind loop syndrome is crucial for acute abdomen cases post-right hemicolectomy.
• Further research is needed to define incidence and optimize management.
