Abstract

BACKGROUND: Self-inflicted abdominal stab wounds (ASWs) are uncommon. The present study aims to characterize the clinical profile of this unique group of psychiatric-surgical patients. METHODS: A retrospective review of 23 patients with intentional self-inflicted ASWs at two urban level I trauma centres during a 10-year period. RESULTS: Most patients were males (70%), ages ranging from 21 to 82 years (mean 40 years). Seventy-four percent of patients had a previous psychiatric history and prior suicide attempts were common (41%). Half of the patients had a positive admission drug or alcohol screen. Hypotension (systolic blood pressure (SBP) < 90 mmHg) was present in only two patients. Mean injury severity, revised trauma and Glasgow coma scores were 5.8, 7.7 and 14.5, respectively. The most commonly used instrument was a knife (87%). There were 1.5 external wounds per patient located primarily in the right upper quadrant (40%) and right lower quadrant (23%). These were associated with extra-abdominal wounds in 22% of cases. Local wound exploration was positive in 15 patients (65%), who all underwent laparotomy. Injured intra-abdominal or retroperitoneal organs were identified in 10 patients and included the stomach, duodenum, small bowel, colon, mesentery, inferior vena cava (IVC) and psoas muscle with a mean of 1.7 injuries per patient. Wound infection was the only post-operative complication (two patients). All eight patients with a negative local wound exploration were observed without complication. Seventy percent of patients were ultimately transferred to a psychiatric ward with a mean length of stay on the surgical service of 8 days. Only one patient died during admission due to metastatic malignant disease. CONCLUSION: Self-inflicted ASWs in suicidal patients can induce significant although most likely non-lethal abdominal and retroperitoneal injuries. This observation should guide the trauma surgeon when treating such patients.
