Summary
Endoscopic dilation effectively treats colonic anastomotic strictures, a complication of surgical stapler use. This minimally invasive procedure offers a safe and reliable alternative to surgery with a low failure rate.
Area of Science:
- Gastroenterology
- Colorectal Surgery
Background:
- Colonic anastomotic strictures can increase after surgical stapler use.
- Symptomatic strictures (2-5% of patients) present challenges with medical or surgical management.
Purpose of the Study:
- To evaluate the efficacy and safety of endoscopic dilation for colonic anastomotic strictures.
- To compare balloon dilation with bougienage for treating these strictures.
Main Methods:
- Retrospective analysis of 42 patients with colonic anastomotic strictures undergoing endoscopic dilation (mechanical or pneumatic).
- Procedures included dilation before stoma reversal (19 patients) or symptom-driven/endoscope-passage-dependent treatment (23 patients).
Main Results:
- Overall failure rate was 2.4% with no reported morbidity or mortality.
- Balloon dilation showed a higher success rate in a single session (76.9%) compared to bougienage (51.8%).
Conclusions:
- Endoscopic dilation is a reliable, simple, and safe primary treatment for colonic anastomotic strictures.
- Surgery is reserved for rare cases of failure or suspected cancer recurrence.
