INTRODUCTION: A post-traumatic mesenteric arteriovenous fistula (AVF) is extremely rare.
CASE
REPORT: A previously healthy 26-year-old male was injured with an abdominal stab wound. Computed tomography (CT) showed liver injury, pancreas injury and a retropancreatic hematoma. We performed the hemostasis of the bleeding due to the liver injury, a distal pancreatectomy with splenectomy and evacuation of the retropancreatic hematoma. On the 5th postoperative day, an abdominal bruit and thrill was detected. CT and angiography showed an AVF between the superior mesenteric artery (SMA) and the inferior mesenteric vein with early enhancement of the portal vein (PV). The point of the AVF was about 4 cm from the SMA's orifice. After an emergent laparotomy and inframesocolic approach, the isolation of the SMA was performed by dissection and ligation of adjacent mesenteric tissues which was about 6 cm length from the nearby SMA orifice, preserving the major side branches of the SMA, because the exact point of the AVF could not be identified despite the shunt flow in the PV being audible during an intraoperative hand-held Doppler-shift measurement. After that, the shunt flow could not be detected by using an intraoperative hand-held Doppler-shift measuring device. CT two and a half months later showed no AVF. There were no major complications during a 19-month follow-up period.
CONCLUSION
Early management of a post-traumatic mesenteric AVF is essential to avoid complications such as hemorrhage, congestive heart failure and portal hypertension.

PURPOSE
Severe pancreaticoduodenal injuries are relatively uncommon, but may result in high morbidity and mortality, especially when management is not optimal, and determining the appropriate treatment is often difficult. The objective of this study was to review our experience and to evaluate the role of a pancreaticoduodenectomy (PD) in treatment of pancreaticoduodenal injuries.
METHODS
We performed a retrospective review of 16 patients who underwent an emergency PD at our hospital for severe pancreaticoduodenal injury from 1990 to 2011. Demographic data, clinical manifestations, mechanism and severity of the injury, associated injuries, postoperative complications and outcomes were reviewed.
RESULTS
The mean age of the 16 patients was 45+/-12 years (mean+/-standard deviation), and 15(93.8%) patients were male. All patients underwent an explorative laparotomy after a diagnosis using abdominal computed tomography. Almost all patients were classified as AAST grade higher than III. Thirteen(83.3%) of the 16 patients presented with blunt injuries; none presented with a penetrating injury. Only one(6.3%) patients had a combined major vascular injury. Fifteen patients underwent a standard Whipple's operation, and 1 patient underwent a pylorus-preserving pancreaticoduodenectomy. Two of the 16 patients required an initial damage-control procedure; then, a PD was performed. The most common associated injured organs were the small bowel mesentery(12, 75%) and the liver(7, 43.8%). Complications were intraabdominal abscess(50%), delayed gastric emptying(37.5%), postoperative pancreatic fistula(31.5%), and postoperative hemorrhage (12.5%). No mortalities occurred after the PD.
CONCLUSION
Although the postoperative morbidity rate is relatively higher, an emergency PD can be perform safely without mortality for severe pancreaticoduodenal injuries. Therefore, an emergency PD should be considered as a life-saving procedure applicable to patients with unreconstructable pancreaticoduodenal injuries, provided that is performed by an experienced hepatobiliary surgeon and the patient is hemodynamically stable.

AbstractAbstract PDF
PURPOSE
Althoughpancreas injury is rare in abdominal trauma,it posesa challengeto the surgeon because its clinicalfeaturesare not prominentand the presence of main duct injurycannot be easily identified by imaging studies. Furthermore, severe pancreas injuries require a distal pancreatectomy or a pancreaticoduodnectomy which are associated considerable morbidity and mortality. We reviewed the clinical features of and outcomes for patients with pancreas injury.
METHODS
For 10 years from Jan. 2001 to Dec. 2010, thirty-four patients were diagnosedas having pancreas injury by using an explo-laparotomy. Patients successfully treated bynon-operative management were excluded. Patients were divided into early (n=18) and delayed surgery groups (n=11) based on an interval of 24hours between injury and surgery. The clinical features of and the outcomes for the patients in both groups were compared.
RESULTS
Males were more commonly injured (82.4% vs.17.6%). The mean age was 37.2 years. The injury mechanisms included vehicle accidents (62.9%, 22/34), assaults (20%, 7/34), and falls (11.4%, 3/34)). The head and neck of the pancreas was most commonly injured, followed by the body and the tail (16, 12, and 6 cases). Of the 34 patients, 26 (76.5%) patients had accompanying injuries. Grade 1 and 2 occurred in 14 (5 and 9) patients, and grade 3, 4, and 5 occurred in 20 (16, 3, and 1) patients. The early and delayed surgery groups showed no difference in surgical outcomes. Two patients with grade 3 in the early surgery group died after surgery,one due tomassive hemorrhage and the other due to septic shock. Of the five patients initially managed non-operatively,three developed peripancreatic necrosis and two developed pseudocyst. All five patients were successfully cured by surgery.
CONCLUSION
All cases of pancreas injury in this study involved blunt injury, and accompanying injury to major vessels or the bowel was the major cause of mortality. Surgery delayed for longer than 24 hours after was not associated with adverseoutcomes.
