Trauma to the gallbladder is associated with concurrent injuries to the extra hepatic biliary system: A South African experience.

INTRODUCTION: Gallbladder trauma is a rare injury. This study aimed to describe the significance of these injuries and the appropriate management strategies. METHODS: A retrospective study was undertaken at a major trauma centre in South Africa and included all patients diagnosed with a gallbladder injury between January 2012 and October 2020. RESULTS: A total of 51 cases were included (88% male, mean age: 38 years), with 44 (86%) penetrating trauma cases [28 stab wounds (SW), 16 sustained gunshot wounds (GSW)]. Of the 7 (13%) blunt trauma cases, five were involved in a motor vehicle crash, and two were injured via assault. All patients underwent laparotomy. Full-thickness gallbladder laceration or perforation was the most common type of injury (84%) and all patients with a gallbladder perforation or laceration had a cholecystectomy at index operation. Two out of 5 patients with a gallbladder contusion were managed conservatively without a cholecystectomy and the remaining three had evidence of gallbladder necrosis which were managed with cholecystectomy. Associated extrahepatic bile duct injuries occurred in 4% of cases, and 18 cases (35%) required intensive care unit (ICU) admission. The overall mortality was 8%. CONCLUSION: Gallbladder injury is rare but when encountered implies a significant degree of trauma. Although cholecystectomy is usually definitive, there is an association with other occult extra-hepatic biliary tract injuries. The severity of the associated injuries usually determines patient outcomes.

Radiographic pneumoperitoneum following abdominal stab wound is not an absolute indication for mandatory laparotomy - A South African experience.

INTRODUCTION: Pneumoperitoneum on chest radiograph (CXR) following abdominal stab wounds (SW) is generally considered as surrogate evidence of viscus perforation and an absolute indication for laparotomy. The exact yield of this radiographic finding is unknown. MATERIALS AND METHODS: A retrospective study was conducted on all patients who presented with abdominal SW with no peritoneal signs but had pneumoperitoneum alone who underwent mandatory laparotomy from December 2012 to October 2020 at a major trauma centre in South Africa. RESULTS: During the 8-year study period, 55 patients were included (91% male, mean age: 24 years). Laparotomy was positive in 67% (37/55). Of the 37 positive laparotomies, 28 (76%) were considered therapeutic and the remaining 9 (24%) were nontherapeutic. The negative laparotomy rate was 33%. A total of 52 organ injuries were identified at laparotomy in the 37 positive laparotomies. Twenty-five per cent (14/55) of patients experienced complications. The complication rate of the subgroup of 18 patients who had a negative laparotomy was 33% (6/18). Two per cent (1/55) of all 55 patients required intensive care admission. The mean length of hospital stay was 6 days. There were no mortalities in this cohort. CONCLUSIONS: Pneumoperitoneum alone in patients with no peritoneal signs on initial assessment following abdominal SW cannot be considered an absolute indication for operative exploration. Up to one third of patients have no intra-abdominal injuries. This specific subgroup of patients can potentially be managed by a selective non-operative management approach.
