Closed traumatism of the distal pancreas (A case series of 6 patients)

Abstract

Introduction and importance: The aim of this retrospective study was to present six cases of trauma to the distal pancreas, highlighting the challenges associated with their diagnosis and management, while underlining their seriousness and the various complications potentially encountered. Our case series highlights individual patient outcomes, demonstrating the diversity of clinical presentations and the importance of customized treatment strategies.

Case series: Between January 2015 and December 2020, six cases of distal pancreas trauma were identified. In two cases, the diagnosis was made based on emergency abdominal CT scans, while in the other four patients, the diagnosis was made directly intraoperatively, mainly because of the severity of the associated lesions, which necessitated laparotomy for exploration.

Clinical discussion: Out of 115 cases of closed abdominal trauma, injury to the distal pancreas was identified in 6 patients, (5.2 %), with a mean age of 21 years. Despite the use of abdominal CT scans for all patients, pancreatic trauma was directly diagnosed intraoperatively in 4 cases (67 %). All patients presented with concomitant abdominal injuries (100 %), and 3 patients (50 %) exhibited multiple severe injuries. Additionally, a significant elevation in pancreatic serum markers was observed in 3 patients (50 %). The pancreatic injuries predominantly involved the tail of the pancreas (67 %), while the body was affected in one patient, and the isthmus was completely transected in another. Three of our patients developed a pancreatic fistula (50 %) and two patients (33 %) passed away; the first had severe associated lesions, and the second, despite undergoing several iterative laparotomies, succumbed to postoperative complications following a left pancreatectomy.

Conclusion: Closed traumatism of the distal pancreas, although rare, is a significant problem. It is often diagnosed during emergency laparotomy but can sometimes be found on preoperative CT scans. When the patient's condition permits, it is highly advisable to undergo a left pancreatectomy. Simple external drainage is reserved for certain specific situations.
