Evaluation of efficacy of endoscopic incision method in postoperative benign anastomotic strictures of gastrointestinal system

Role of endoscopic interventions and electroincision in benign anastomotic strictures following colorectal surgery

BACKGROUND/AIMS

The anastomotic strictures are one of the most common colorectal surgery complications, and various endoscopic techniques have been defined. Balloon dilation is the most well-known and the simplest procedure. In this article, we aimed to present our series of endoscopic interventions and electroincision management for anastomotic strictures.

MATERIALS AND METHODS

The files of 59 patients, who underwent colorectal surgery between January 2010 and September 2017 in our hospital and were diagnosed during the follow-up with anastomotic stricture, were analyzed. The outcomes of endoscopic interventions such as balloon dilation and electroincision were compared and reported.

RESULTS

The mean age of the 59 patients included in the study was 59.5±16.26 years. The primary operative indications were colorectal cancer in 46, inflammatory bowel disease in 7, diverticulum in 5, and penetrating trauma in one patient. Single- or multiple-balloon dilations were successful in 48 patients. Electroincision was performed in 11 patients because of the balloon dilation failure. None of the patients needed a secondary surgery. During the mean 33.75 months of the follow-up, the stricture recurred in seven patients who had undergone balloon dilation. Repeated balloon dilation was successful in these patients without any need for an additional surgical intervention.

CONCLUSION

Balloon dilation can be performed safely as the primary treatment option, because of its easy access and noninvasive application. Electroincision is also a safe and effective endoscopic technique that can be preferred especially when the balloon dilation fails.
