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.

Purpose: Clinical features of Pancreatic Neuroendocrine Tumors (PETs) vary according to the hormone secreted and to the heredity of the tumors. Malignant PETs are common among nonfunctioning PETs (NFTs) whereas the majority of functioning PETs (FTs) are benign. Our goal was to determine the clinical features and prognosis of PETs stratified by the WHO classification scheme and AJCC-UICC 7TH TNM staging. Methods: We selected for study 30 patients with PETs, including one case of nesidiolastosis, who presented at our clinic between April 1992 and June 2010. Clinicopathological features were studied retrospectively. PETs were classified as benign, uncertain malignant, well differentiated carcinoma, or poorly differentiated carcinomas by the WHO classification. For statistical analysis, Student"s t-test, the Chi-square test, and the Kaplan-Meier method were utilized. Results: Nine cases were FTs and twenty one cases were NFTs. The average size of the FTs was smaller than that of the NFTs (1.71 vs 4.33, p=0.04). The head of the pancreas was most commonly involved (33.3% of FTs; 47.6% of NFTs) but the locations of the tumors were not different. Insulinoma was the most common (66.7%, 6/9) among FTs. The incidence of malignant tumors was 33.3% and 55.0% among, respectively, FTs and NFTs. The 5-year disease-free survival rate of patients with benign PETs (FTs and NFTs), and of patients with functioning well-differentiated carcinomas was 100%. However, the 5-year disease-free survival rates of patients with nonfunctioning well- and poorly-differentiated carcinomas were 66.7% and 0%. Conclusion: Among patients with Pancreatic Neuroendocrine Tumors, malignant tumors are more common among NFTs than FTs. Poorly-differentiated carcinomas have a worse prognosis while all FTs regardless of their WHO classification fail to show any disease recurrence.
