Background
Increasing colonoscopy use increases the incidence of iatrogenic colon perforation. Operative management of iatrogenic colonoscopic perforation is diverse. This study retrospectively reviewed our experiences in treating diagnostic colonoscopy-associated bowel perforation by laparoscopic direct suturing.
Methods
A total of 89,014 patients underwent diagnostic colonoscopy at our institution during the past 6 years. We identified 17 iatrogenic perforations (0.019 %) that were all managed by laparoscopic direct suturing.
Results
Perforation patients included 11 men and 6 women (mean age 60 ± 18 years). Sixteen patients (94 %) had severe comorbidities or previous abdominal surgery. Perforations were noticed by the endoscopist during the procedure in 13 cases (76 %) while the remaining 4 cases (24 %) were diagnosed within 24 h after colonoscopy. The estimated mean longitudinal perforation length was 4.4 ± 2.1 cm. Mean operation time was 2.3 ± 0.6 h, without significant blood loss or other severe complication. The mean time to bowel function return was 3.4 ± 1.2 days, the mean time to initial oral intake was 3.9 ± 2.0 days and the mean hospitalization duration was 6.8 ± 4.2 days.
Conclusions
Diagnostic colonoscopic perforation occurred in less than 2/10,000 patients when colonoscopy was performed by experienced operators in our endoscopy center. Most of the perforation patients had severe comorbidities, to which the surgeon should pay close attention during colonoscopy. Laparoscopic primary suture of colon perforations caused by diagnostic colonoscopy is a safe and feasible repair method. Further efforts will definitively assess the feasibility of routinely using laparoscopic direct suture to repair colon perforations.
