ABSTRACT: Neuroendocrine gastro-entero-pancreatic neoplasms (GEP-NENs) constitute a heterogeneous group of tumors, whose incidence has increased over the years. The most frequent site for primary disease is the stomach followed by small and large intestine, and pancreas. In the last decade, a dramatic growing in the incidence of small, incidental GEP-NENs has been recorded. In parallel, an increasing attitude toward more conservative approaches instead of surgical management has being widely spreading. This is particularly true for small, asymptomatic, pancreatic NEN as for these tumor forms an active surveillance has proven to be safe and feasible. Primary site and biological features of the neoplasms lead to different strategies and indications for surveillance and follow-up. This review focuses on the current evidence on modality and timing of surveillance and conservative treatment of incidentally discovered lesions.

ABSTRACT: AIM: To evaluate the safety and feasibility of laparoscopic spleen-preserving distal pancreatectomy (LSPDP) with autologous islet transplantation (AIT) for benign tumors of the pancreatic body-neck. METHODS: Three non-diabetic, female patients (age 37, 44 and 35 years, respectively) were declared candidates for surgery, between May and September 2011, because of pancreatic body/neck cystic lesions. The planned operation was an LSPDP associated with AIT from the normal pancreas distal to the neoplasm. Islets isolation was performed on the residual pancreatic parenchyma after frozen section examination of the margin. Purified autologous islets were infused into the portal vein by a percutaneous transhepatic approach the day after surgery. RESULTS: The procedure was performed successfully in all the three cases, and the spleen was preserved along with its vessels. Mean operation time was 283 ± 52 min and average blood loss was 133 ± 57 mL. Residual pancreas weights were 33, 22 and 30 g, and 105.200, 40.390 and 94.790 islet equivalents were isolated, respectively. Surgical complications occurred in one patient (grade A pancreatic fistula). Postoperative stays were 6, 6 and 7 d, respectively. Histopathological evaluation revealed mucinous cystic neoplasm in cases 1 and 3, and serous cystic neoplasm in patient 2. No postoperative insulin administration was required. One patient developed a transient partial portal thrombosis 2 mo after islet infusion. Patients are insulin independent at a mean follow up of 8 ± 2 mo. CONCLUSION: Combination of LSPDP and AIT is feasible and could be effective to minimize the surgical impact for benign neoplasm of pancreatic body-neck.

3 Article A prognostic score to predict major complications after pancreaticoduodenectomy. 2011

Braga, Marco / Capretti, Giovanni / Pecorelli, Nicolò / Balzano, Gianpaolo / Doglioni, Claudio / Ariotti, Riccardo / Di Carlo, Valerio. ·Department of Surgery, Vita-Salute San Raffaele University, Milan, Italy. braga.marco@hsr.it ·Ann Surg · Pubmed #22042466.

ABSTRACT: OBJECTIVE: To develop and validate a simple prognostic score to predict major postoperative complications after pancreaticoduodenectomy (PD). BACKGROUND: PD still carries a high rate of severe postoperative complications. No specific score is currently available to stratify the patient's risk of major morbidity. METHODS: Between 2002 and 2010, preoperative, intraoperative, and outcome data from 700 consecutive patients undergoing PD in our institution were prospectively collected in an electronic database. Major complications were defined as levels III to V of Clavien-Dindo classification. On the basis of a multivariate regression model, the score was developed using a random two-thirds of the population (n = 469) and was validated on the remaining 231 patients. RESULTS: Major complication rate was 16.7% (117/700). Significant predictors included in the scoring system were: pancreas texture, pancreatic duct diameter, operative blood loss, and ASA score. The mean risk of developing major postoperative complications was 7% in patients with score 0 to 3, 13% in patients with score 4 to 7, 23% in patients with score 8 to 11, and 36% in patients with score 12 to 15. In the validation population, the predicted risk of major complications was 15.2% versus a 16.9% observed risk (C-statistic index = 0.743). CONCLUSION: This new score may accurately predict a patient's postoperative outcome. Early identification of high-risk patients could help the surgeon to adopt intraoperative and postoperative strategies tailored on individual basis.
