[Open surgical versus laparoscopic treatment of iatrogenic colon perforation - results of a 13-year experience].

BACKGROUND

Iatrogenic colon perforation is a rare but life-threatening complication of colonscopy. As in other diseases, laparoscopic treatment has increasingly been propagated for the treatment of colonic disorders in the last years. The aim of this comparative study was to answer the question of whether laparoscopic surgical treatment may serve as a suitable treatment for the acute colon perforation comparable to open surgery.

PATIENTS AND METHODS

The data of all patients who underwent surgery for iatrogenic colon perforation within a 13-year time period (1997-2009) were recorded prospectively and analysed retrospectively with regard to different perioperative parameters. In the following analysis the laparoscopically and open surgically treated patients were compared.

RESULTS

In the observation period 24 patients with iatrogenic colon perforation were treated laparoscopically and 12 patients with open surgery. There were no significant differences concerning age in both groups. In both groups resection of the affected region was preferred [open surgically: 58 % (n = 7), laparoscopically: 80 % (n = 19)]. The median operation time was 105 min (range: 35 - 180) for the open surgically treated patients and 165 min (90 - 420) for laparoscopic procedures (p = 0.006). In 4 cases of the laparoscopic group a conversion via laparotomy was -necessary. There was no significant difference concerning the hospital stay between both groups with 14.5 days (7-40) for the open surgical and 11 days (7-25) for the laparoscopic group. Concerning the postoperative morbidity a significantly higher incidence could be seen in the open surgical group (p < 0.0001).

CONCLUSION

An iatrogenic colon perforation mostly leeds to the immediate indication for a surgical treatment. The morbidity and mortality is -primarily determined through the appearance of postoperative complications due to delays in diagnostics and treatment. In this study the feasibility of a laparoscopic treatment could be shown. The laparoscopy with its minimal access trauma offers an enlargement of the diagnostics as well as a safe treatment of the perforation in most patients. However, the laparoscopic treatment especially in emergancy situations requires -advanced experience of the surgeon and always needs a critical benefit-risk consideration in the individual situation.
