| Abstract: | Following the experience of World War II, exploratory laparotomy in all patients with penetrating abdominal trauma was deemed mandatory until 1960 when Shaftan reported his experience with selective laparotomy. In 1973, Nance et al. reported on selective observation of abdominal stab wounds. There seems to be little controversy over mandatory laparotomy for abdominal gunshot wounds. Blunt trauma is generally managed expectantly with the adjunctive use of peritoneal lavage, CT scanning, and serial examinations of the abdomen. Despite the selective approach and the use of adjunctive diagnostic methods, exploratory laparotomy continues to be the most accurate method used to diagnose the presence of intra-abdominal injury. In order to examine our experience with diagnostic laparotomy for trauma, both blunt and penetrating, a retrospective study of 494 consecutive patients undergoing exploratory laparotomy over the past 4 years was undertaken. Abdominal stab wounds were explored under local anesthesia, and, if found to penetrate the posterior fascia, laparotomy was accomplished. All patients with abdominal gunshot wounds underwent exploration. Exploratory laparotomy in patients with blunt abdominal trauma was mandated by clinical signs, positive peritoneal lavage, or positive CT scan. All patients with unexplained shock and/or signs of peritoneal irritation underwent urgent laparotomy. In this series of 494 patients, 99 or 20 per cent of the entire group had a negative exploration (30% for stab wounds, 16% for gunshot wounds, and 19% for blunt abdominal trauma). The morbidity for the negative laparotomy group was limited to five patients with postoperative atelectasis. There were no anesthesia complications, iatrogenic intraoperative injuries, or wound infections. There were five deaths but none were laparotomy-related.(ABSTRACT TRUNCATED AT 250 WORDS) |
