Abstract

PURPOSE
The management of a colonoscopic perforation (CP) varies from conservative to surgical. The objective of this study was to evaluate the outcomes between surgical and conservative treatment of patients with a CP.
METHODS
From 2003 to 2016, the medical records of patients with CP were retrospectively reviewed. Patients were divided into 2 groups depending on whether they initially received conservative or surgical treatment.
RESULTS
During the study period, a total of 48 patients with a CP were treated. Among them, 5 patients had underlying colorectal cancer and underwent emergency radical cancer surgery; these patients were excluded. The mean age of the remaining 43 patients was 64.5 years old, and the most common perforation site was the sigmoid colon (15 patients). The initial conservative care group included 16 patients, and the surgery group included 27 patients. In the conservative group, 5 patients required conversion to surgery (failure rate: 5 of 16 [31.3%]). Of the surgery group, laparoscopic surgery was performed on 19 patients and open surgery on 8 patients, including 2 conversion cases. Major postoperative complications developed in 11 patients (34.4%), and postoperative mortality developed in 4 patients (12.5%). The only predictor for poor prognosis after surgery was a high American Society of Anesthesiologists physical status classification.
CONCLUSION
In this study, conservative treatment for patients with a CP had a relatively high failure rate. Furthermore, surgical treatment showed significant rates of complications and mortality, which depended on the general status of the patients.
