Nontherapeutic laparotomies revisited

A wide variability exists in the reported incidents of complications following nontherapeutic laparotomy for trauma. We undertook this study to examine the decision-making leading to and complication rates related to the use of nontherapeutic laparotomy in an era of nonoperative management. We conducted a retrospective chart review of all nontherapeutic laparotomies as defined by the operating surgeon performed between May 1998 and May 2001. A total of 50 patients (6%) underwent nontherapeutic laparotomies predominantly for penetrating injury. The most frequent preoperative reason for nontherapeutic laparotomy was the question of hollow viscous or diaphragmatic injury on preoperative studies. Peritoneal signs on examination and peritoneal penetration on wound exploration were also frequent indications for surgery. Significant complication rates were low at approximately 12 per cent. Total length of stay was 7.3 days and 5 days if patients with significant other associative injuries were excluded. Overall morality was 4 per cent and unrelated to the nontherapeutic laparotomy in all cases. Overall incidence of nontherapeutic laparotomy has decreased with the use of abdominal helical CT and triple-contrast CT to evaluate penetrating injuries. Despite these advances diaphragmatic and hollow viscous injuries remain a concern. Although overall serious complication rates were low the use of nontherapeutic laparotomy adds significantly to length of stay and complications.
