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.

In spite of lack of randomized control study, laparoscopic distal pancreatectomy (DP) is regarded as appropriate treatment in managing benign and low grade malignant tumor in distal part of the pancreas. With the advance of laparoscopic skills, innovative instruments, and perioperative management, clinical effort to reduce the access injury for laparoscopic DP has been attempted to enhance the cosmetic effect and the benefit of minimally invasive surgery. Due to inborn technical limitation of laparoscopic surgical system, it is not easy to perform laparoscopic reduced port-or single port-distal pancreatectomy (LRP/LSP-DP) in daily routine clinical practice, however, surgical technique for safe and effective LRP/LSP-DP has been developed. Till now, only a few experts reported the technical feasibility and safety of LRP/LSP-DP in selected patients. According to literature review, the number of the patients who underwent LRP/LSP-DP seems to gradually increase. In this moment, surgical experiences may be too limited to reach the conclusion, but, with the help of robotic surgical system, LRP/LSP-DP has potential room for further investigation. Therefore, minimally invasive surgeons need to pay attention to this innovative movement. In this review, currently available surgical techniques for LRP/LSP-DP has been summarized with some future perspectives on this technique.

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.

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.
