Intraductal tubulopapillary neoplasm (ITPN) of the pancreas has been recently reported. It is very rare, therefore clinical behavior and prognosis has not yet been characterized. We experienced a case of ITPN of the pancreas which presented with acute pancreatitis and treated with Whipple's operation. Histopathologic finding showed papillary hyperplasia with carcinomatous change. The tumor recurred after 47 month of operation, and she underwent total pancreatectomy. Pathologic finding revealed tubulopapillary growth with high grade dysplasia. Immunohistochemial staining was not performed, however gross and microscopic findings were compatible with ITPN of the pancreas. We report a case of ITPN of the pancreas.

OBJECTIVETo analyze the prognostic factors of pancreatic neuroendocrine neoplasms (PNEN).

METHODSClinical data of 61 patients with PNEN from March 1992 to December 2012 was retrospectively analyzed. There were 23 male and 38 female patients, with a median age of 52 years (ranged from 22 to 68 years). Forty-one patients were non-functional tumors, and 20 patients were functional tumors. Fifty-nine patients received operation, 13 (22.0%) patients underwent laparoscopic operation, 2 patients underwent puncture biopsy under CT guidance. Survival was analyzed with the Kaplan-Meier method.

RESULTSAmong these patients, 53 (86.9%) patients underwent curative resection. The cases of grade G1, G2, G3 were 41 (67.2%), 9 (14.8%), 11 (18.0%), respectively. The cases of stageI, II, III, IV were 47 (77.0%), 7 (11.5%), 2 (3.3%), 5 (8.2%), respectively. Liver metastasis, neural invasion were found in 5 cases (8.2%), 5 cases (8.2%), respectively. The median follow-up period was 40 months (ranged from 3 to 209 months). The overall 1-, 3-, 5-year survival rates were 92.0%, 89.7%, 86.3%, respectively. Univariate analysis showed WHO classification (χ(2) = 18.503), TNM staging system (χ(2) = 23.401), liver metastasis (χ(2) = 18.606), neural invasion (χ(2) = 10.091), resection status (χ(2) = 25.514) were prognostic factors of PNEN (all P = 0.000).

CONCLUSIONSSurgical resection in PNEN results in long-term survival. WHO classification, TNM staging, resection status are effective in predicting the prognosis of PNEN. Liver metastasis, neural invasion predicted poor prognosis.

Severe acute pancreatitis (SAP) is hard to treat for the abrupt onset, critical condition and complicated pathophysiology. Historically, the treatment strategy of SAP hovered between surgical intervention and conservative treatment. At the turn of the 20(th) century, SAP was reported to be cured by surgical intervention in a series cases, which lead to the dominance of surgical intervention in SAP treatment. Subsequently, SAP was documented to respond to nonoperative therapy. A wave of conservatism emerged, and surgical intervention for SAP was rarely practiced for the next 3 decades. However, surgeons refined the indications and considered new approaches for surgical treatment in 1960s because of the poor outcomes of conservation, and surgical interventions was mainly performed at early stage of SAP. However, a series of prospective studies showed that conservative treatment of patients with sterile pancreatic necrosis is superior to surgical intervention, and that delayed intervention provide improved outcomes in 1990s, which changed the treatment concept of SAP again. The modern treatment concept formed during the progression: organ supportive care dominates in the early stage of the disease, and surgical intervention should be performed at late stage with proper indications. Despite the advances in treatment, the morbidity of SAP is still 5%-20%, which suggests the pancreatic surgeons' exploration in the future.

Cystic lesions in the accessory spleen are extremely rare and they present a challenging clinical differential diagnosis. We report here on two cases of epithelial cyst of intrapancreatic accessory spleen that mimicked pancreatic cystic tumor. In both cases, the patients underwent distal pancreatectomy under the impression of a benign cystic tumor of the pancreas. Unilocular or multilocular cysts in the pancreas tail were observed, and these were later shown to be epithelial cysts in the accessory spleen located within the pancreatic tail. The cysts were lined by columnar, cuboidal or stratified squamous epithelium.

Pancreatic arteriovenous malformation (AVM) is an extremely rare condition with various clinical manifestations. We report herein a case of recurrent acute pancreatitis due to pancreatic AVM in a 49-year-old man. This patient presented with epigastric pain that had developed after consuming alcohol 2 days prior to admission. Serum amylase and lipase levels were elevated and computed tomography revealed focal low-attenuation lesions with peripancreatic infiltrations in the pancreatic tail and multiple collateral vessels around the low-attenuation lesions. He was diagnosed with acute pancreatitis and pancreatic AVM. Although he had stopped drinking after the first attack of acute pancreatitis, his pancreatitis recurred twice within 3 months. He underwent a distal pancreatectomy after the third attack of acute pancreatitis. He was free of symptoms for 2 years after the pancreatectomy.

PURPOSE: Pancreaticoduodenectomy (PD) or distal pancreatectomy (DP) are treatments used for pancreatic benign neoplasms even though both of these treatments result in significant loss of normal pancreatic parenchyma; this leads to subsequent impairment of exocrine and endocrine pancreatic function. The purpose of this study is to provide short-and long-term result of limited resection (LR) in a single center. METHODS: Two-hundred thirty patients who had undergone pancreatic resection between April 1998 and September 2008 for benign neoplasms were reviewed retrospectively. DP was performed in 102 patients, LR in 77, PD in 51 patients. The definitions of the International Study Group of Pancreatic Fistula (ISGPF) were applied to postoperative pancreatic fistulas (POPF), perioperative endocrine function was evaluated through oral glucose tolerance test. RESULTS: LR includes 42 enucleation, 24 central pancreatectomy, and 11 uncinate process resection. No deaths occurred to patients during the study review period; POPF was detected in 50 patients (65%), 37 patients with grade A and 13 patients with grade B or C. POPF occurred 65% of the time after LR, more frequently compared to the occurrance after PD or DP (58%), but this was not statistically significant (P =.322). After LR, there were 2 patients with new onset diabetes (3%), while 26 (17%) patients developed diabetes after DP or PD (P = .002). CONCLUSION: LR may preserve endocrine and exocrine function. While mortality is low with the use of LR, it is associated with a higher pancreatic-leakage rate. The precise management of benign pancreatic lesions remains in evolution.

PURPOSE: Despite recent advances in laparoscopic pancreatic surgery, few studies have compared laparoscopic central pancreatectomy (LCP) with open central pancreatectomy (OCP). The aim of this study was to compare clinical outcomes between LCP and OCP as a single institutional study. METHODS: During the study period (From January, 1998 to December, 2010), we performed central pancreatectomy in 95 cases. Among them, 26 cases of totally LCP and 55 cases of OCP were compared retrospectively. RESULTS: Benign pancreatic neoplasm was the main indication. The mean operation time for the LCP group (350.2 min) was longer than that for the OCP group (283.4 min). And there was no significant difference in mean actual blood loss (477 ml versus 714 ml, p=0.083) between the LCP and OCP groups. Return to a normal bowel movement and resumption of a liquid diet were achieved 5.5+/-2.6 days after the operation in the LCP group and 6.6+/-2.0 days after the operation in the OCP group (p=0.039). The mean duration of postoperative hospital stay was 13.8 days for the LCP group, which was significantly shorter than the 22.5 days for the OCP group (p=0.015). The overall complication rate was 42.3% (11 cases) in the LCP group and 45.5% (25 cases) in the OCP group (p=0.790). CONCLUSION: Use of LCP for benign or low grade malignant lesions of the pancreatic neck portion is feasible and safe. Compared to the open method, the laparoscopic approach to central pancreatectomy appears to provide advantages of early resumption of a normal diet and reduction of postoperative hospital stay without further complications.
