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.

Laparoscopic spleen-preserving distal pancreatectomy has been widely performed for benign and borderline malignancy in the body or tail of the pancreas when there are not oncologic indications for splenectomy. As the need for minimally invasive procedures to reduce postoperative morbidity and improve the quality of life is increasing, many surgeons have attempted to reduce the number of trocars and incision size to minimize access trauma and scarring. Single-port laparoscopic spleen-preserving distal pancreatectomy is the result of these efforts; however it has many limitations such as technical difficulty and prolonged operation time. In this article, we report the first case of dual-incision laparoscopic spleen-preserving distal pancreatectomy, proving that it can be a safe and feasible minimally invasive procedure for benign or borderline malignant tumors in the body or tail of the pancreas.

PURPOSE: The consumers' preferences are not considered in developing or implementing new medical technologies. Furthermore, little efforts are made to investigate their demands. Therefore, their preferred surgical method and the factors affecting that preference were investigated in pancreatic surgery. METHODS: Six-hundred subjects including 100 medical personnel (MP) and 500 lay persons (LP) were surveyed. Questionnaire included basic information on different methods of distal pancreatectomy; open surgery (OS), laparoscopic surgery (LS), and robotic surgery (RS). Assuming they required the operation, participants were told to indicate their preferred method along with a reason and an acceptable cost for both benign and malignant conditions. RESULTS: For benign disease, the most preferred method was LS. Limiting the choice to LS and RS, LS was preferred for cost and well-established safety and efficacy. OS was favored in malignant disease for the concern for radicality. Limiting the choice to LS and RS, LS was favored for its better-established safety and efficacy. The majority thought that LS and RS were both overpriced. Comparing MP and LP responses, both groups preferred LS in benign and OS in malignant conditions. However, LP more than MP tended to prefer RS under both benign and malignant conditions. LP thought that LS was expensive whereas MP thought the cost reasonable. Both groups felt that RS was too expensive. CONCLUSION: Though efforts for development of novel techniques and broadening indication should be encouraged, still more investments and research should focus on LS and OS to provide optimal management and satisfaction to the patients.
