The use of laparoscopy in managing penetrating thoracoabdominal injuries in Africa: 83 cases reviewed.

backgroundThe use of laparoscopy in managing haemodynamically stable patients with penetrating thoracoabdominal injuries in developed countries is wildly practiced, but in Africa, the use of laparoscopy is still in its infancy stage. We reviewed a single centre experience in using laparoscopy in Africa for management of patients with both isolated diaphragmatic injuries as well as diaphragmatic injuries associated with intra-abdominal injuries requiring intervention.

methodsA retrospective analysis of prospectively collected data of patients presenting with penetrating thoracoabdominal injuries was done. All patients offered laparoscopic exploration and repair from January 2012 to December 2015 at Dr. George Mukhari Academic Hospital were analysed. Means (±SD) were presented for continuous variables, and frequencies (%) were presented for categorical variables. All analyses were performed using SAS version 9.3 (SAS Institute, Cary, NC).

resultsA total of 83 stable patients with penetrating thoracoabdominal injuries managed with laparoscopy met the inclusion criteria and were included in the study. The Injury Severity Score ranged from 8 to 24, with a median of 18. The incidence of diaphragmatic injuries was 54%. Majority (46.8%) of patients had Grade 3 (2-10 cm defect) diaphragmatic injury. Associated intra-abdominal injuries requiring intervention were encountered in 28 (62%) patients. At least 93.3% of the patients were treated exclusively with laparoscopy. The morbidity was encountered in 7 (16%) patients; the most common cause was a clotted haemothorax Clavien-Dindo III-b, but only 1 patient required a decortication. There was one non-procedure-related mortality.

conclusionsA success rate of 93% in using laparoscopy exclusively was documented, with an overall 82% uneventful outcome. The positive outcomes found in this study when laparoscopy was used in stable patients with thoracoabdominal injuries support similar work done in other trauma centres. However, in addition, this study seem to suggest that the presence of peritonitis in stable patient is not a contra-indication to laparoscopy and thoracoscopy may be useful especially in right side diaphragmatic injury where the liver can preclude adequate visualization of the entire diaphragm and to thoroughly clean the chest cavity and prevent future complication such as residual clotted haemothorax.
