A new tailored protocol based on laparoscopy in the management of abdominal shotgun injuries: a case-series study

Abdominal shotgun injuries derive their significance from the wide range of injuries they cause. The management of this type of injury has been continuously evolving. Despite the ongoing incorporation of laparoscopy in management of abdominal trauma, there is no definite protocol raising the role of laparoscopy in such injuries. In this study, we outlined a tailored protocol in the management of penetrating abdominal shotgun injuries differing from the previous protocols which comprised either mandatory exploration or non-operative management.

This case-series study included patients who attended to our emergency department with a shotgun injury involving the abdomen between December 2014 and October 2016. Only stable patients with no clinical signs of surgical abdomen, in combination with CT evidence of penetrating intra-abdominal pellets, were subjected to laparoscopic exploration in this study.

Thirty patients fulfilled the inclusion criteria. During laparoscopy, ten patients were designated as positive for injuries. No missed injuries were identified. Two of the cases identified as positive by laparoscopy needed no further management while the remaining eight patients warranted laparotomy. Only one of these eight patients turned out to have a non-therapeutic exploration. Consequently, laparoscopy in the management of these injuries had an overall accuracy of 96.7%, sensitivity of 100%, specificity of 95.7%, positive predictive value of 87.5% and negative predictive value of 100% with highly significant p value < 0.001.

A tailored protocol relying on the use of laparoscopy in the management of stable patients with CT evidence of penetrating abdominal shotgun injuries is safe and helps to cut down the number of non-therapeutic laparotomies with consequent decrease of complications.
