Purpose Optimal management of colonoscopic perforation (CP) is controversial because early diagnosis and prompt management play critical roles in morbidity and mortality. Herein, we evaluate the outcomes and clinical characteristics of patients with CP according to treatment modality to help establish guidelines for managing CP. Methods Our retrospective analysis included 40 CP patients from January 1, 2003, to December 31, 2014. Patients with CP were categorized into 2 groups according to therapeutic modality: operation (surgery) and nonoperation (endo-luminal clip application or conservative treatment) groups. Results The postoperative morbidity rate was 40%, and no mortalities were noted. The incidence of abdominal pain and tenderness in patients who received only conservative management was significantly lower than in those who underwent surgery (P Conclusion The time of diagnosis and the injury mechanism may be useful indications for conservative management. Nonoperative management, such as endo-luminal clip application, might be beneficial, when feasible, for the treatment of patients with CP.
