Role of laparoscopy in blunt perforations of the small bowel.
BACKGROUND
The purpose of this study was to determine whether laparoscopy could improve our ability to diagnose and treat perforations of the small bowel.


METHODS
From 1985 to 2001, among 250 patients admitted for a blunt abdominal trauma, 195 surgical explorations were performed, comprising 42 laparoscopies. On admission, 108 patients underwent an abdominal ultrasonography (US) and 104 a computed tomography (CT). Thirty-nine patients had a blunt small bowel trauma (BSBT) that was explored and/or treated by laparoscopy (n = 15) or celiotomy (n = 24). We compared the patients who underwent emergency surgery (23) and those who were operated on after a mean delay of 51 h.


RESULTS
On admission, for detecting free intraperitoneal fluid with a BSBT, the sensitivity of CT was 93.3% and specificity was 13.6%. Regarding the 23 patients who underwent emergency surgery, 8/20 had positive US and 10/15 had positive CT, whereas the 15 celiotomies and 8 laparoscopies indicated BSBT. Regarding the 16 patients who underwent delayed surgery, 9 patients underwent a celiotomy and 7 a laparoscopy; all BSBTs were diagnosed. In searching for BSBT, the sensitivity and specificity of laparoscopy were both 100%, whereas the sensitivity of CT was 83.3% and specificity was 22.2%. Twenty of 23 patients undergoing emergency surgery had bowel suture repair compared to 3/16 after delayed surgery. In contrast, a resection was necessary in 10/12 patients treated after a delay compared to 2/17 operated in emergency. Five BSBTs were sutured by laparoscopy, whereas 10 required conversion. Laparoscopy avoided celiotomy in 15 cases. There were no deaths and no enterostomy.


CONCLUSIONS
In hemodynamically stable patients with blunt abdominal trauma, laparoscopy safely and effectively identifies small bowel injuries. Early recognition of these injuries and timely surgical treatment offer the best prognosis.
