There are few studies on postoperative complications after colonoscopic perforation. We aimed to study clinical characteristics and treatment after colonoscopic perforation, and to determine risk factors for postoperative complications by surgical treatment of colonoscopy perforation. Cases with perforation within 7 days after colonoscopy from January 2017 to December 2019 were collected for retrospective analysis. Data regarding demography, clinical information, colonoscopy, perforation, and operation were collected. Single-factor analysis and Spearman correlation analysis were employed to determine the risk factors of postoperative complications. A total of 35,243 colonoscopy examinations were performed during the study period, of which 18 cases of colonoscopic perforation were included in the criteria. Most perforations occurred in the rectosigmoid junction (3 cases) and sigmoid colon (11 cases). All perforation patients received operational treatment, and the incidence of postoperative complications was 38.9%, but no deaths. There were 7 patients who developed postoperative complications. Spearman correlation analysis showed that preoperative medication of glucocorticoid and nonrectosigmoid perforation were positively related to postoperative complications ( < .05), while perforation diagnosed immediately and satisfying intestinal cleanliness were negatively related to it ( < .05). Perforation is a rare but serious complication of colonoscopy, which mostly occurs in the rectosigmoid junction and sigmoid colon. Laparoscopic primary repair is safe and feasible in resolving colonic perforation due to colonoscopy, and postoperative complications were significantly related to perforation site, preoperative medication of glucocorticoid, perforation diagnosis time, and intestinal cleanliness.

The relating of causes to the effects they produce. Causes are termed necessary when they must always precede an effect and sufficient when they initiate or produce an effect. Any of several factors may be associated with the potential disease causation or outcome, including predisposing factors, enabling factors, precipitating factors, reinforcing factors, and risk factors.

Factors that can cause or prevent the outcome of interest, are not intermediate variables, and are not associated with the factor(s) under investigation. They give rise to situations in which the effects of two processes are not separated, or the contribution of causal factors cannot be separated, or the measure of the effect of exposure or risk is distorted because of its association with other factors influencing the outcome of the study.
