- Abstract
Introduction A relaparotomy for a pancreatic fistula (PF) after a pancreaticoduodenectomy (PD) is a formidable operation, and the appropriate treatment of anastomotic leakage is under debate. The objective of this study was to compare the outcomes of different strategies in managing the pancreatic remnant during a relaparotomy for PF after a PD. Methods In this retrospective study on prospectively collected data, 669 PD were performed between 2004 and 2011. The study group comprised 31 patients requiring a relaparotomy, because of delayed haemorrhage (n = 19) or sepsis (n = 12). The pancreatic stump was treated either using pancreas-preserving techniques (simple drainage or duct occlusion) or completion of a pancreatectomy (CP). In 2008, autologous islet transplantation (AIT) was introduced for endocrine tissue rescue of CP. Results The mortality rate, blood loss and transfusion requirement were similar for all techniques. Patients undergoing a CP required a further relaparotomy less frequently than patients with pancreas preservation (7% versus 59%, P < 0.01), and the intensive care unit (ICU) stay was reduced after CP (P = 0.058). PF persisted at discharge in 66% of patients after pancreas-preserving techniques. AIT was associated with CP in 7 patients, of whom one died post-operatively. Long-term graft function was maintained in four out of six surviving patients, with one insulin-independent patient at 36 months after transplantation. Conclusions When a PF requires a relaparotomy, CP has become our favoured technique. AIT can reduce the metabolic impact of the procedure.

- 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.

- 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.

Intrahepatic cholangiocarcinoma (ICC) is still a relatively uncommon indication for laparoscopic surgery because of technical challenges related to the frequent need for major hepatectomies and the necessity to perform formal regional lymphadenectomy. The aim of the present case-matched study was to compare laparoscopic and open resections for ICC. In a case-matched retrospective analysis, 20 consecutive patients who had undergone laparoscopic resection for ICC (LPS group) were compared with 60 of 83 patients who had undergone open surgery (open group) in the same institution. The groups were matched in a ratio of 1:3 using propensity scores based on covariates representing relevant patient characteristics and severity of disease. The main endpoints were short- and long-term outcomes and impact and adequacy of laparoscopic lymphadenectomy. The groups were well matched in terms of patient and disease characteristics. The laparoscopic approach resulted in less blood loss (200 vs. 350 mL, p = 0.040) despite less extensive use of the Pringle maneuver. There was no difference in perioperative morbidity and mortality rates; however, the laparoscopic approach was associated with faster functional recovery (median 3 vs. 4 days, p = 0.050). After a mean follow-up of 39 months, disease-free and overall survivals were 33 and 51 months, respectively, for the LPS and 36 and 63, respectively, for the open group (p ns). The number of harvested nodes was comparable between groups. Compared with open surgery, laparoscopic resection of ICC is feasible and safe, providing short-term benefits without negatively affecting oncologic adequacy in terms of rate of R0 resections, depth of margins, and long-term overall and disease-free survivals. Laparoscopic regional lymphadenectomy is technically possible but should be the object of future focused studies.

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.

Enhanced recovery after surgery (ERAS®) pathways have reduced morbidity and length of hospital stay (LOS) in orthopedics, bariatric, and colorectal surgery. New perioperative care protocols have been tested in patients undergoing pancreaticoduodenectomy (PD), with controversial results on morbidity. Incomplete data about ERAS items compliance have been reported. The aim of this study was to assess compliance with an ERAS protocol and its impact on short-term outcome in patients undergoing PD. A comprehensive ERAS protocol was applied in 115 consecutive patients undergoing PD. Each ERAS patient was matched with one patient who received standard perioperative care. Match criteria were age, gender, malignant/benign disease, and PD-specific prognostic score. No adverse effect related to ERAS items occurred. Compliance with postoperative items ranged between 38 and 66 %. The ERAS group had an earlier recovery of mobilization (p

Diffusion of laparoscopic major hepatectomies is experiencing a steady increasing trend, although slower compared to minor resections. The aim of this single-center study is to discuss current trends and indications in the application of minimally invasive techniques to major hepatic resections. Preoperative patients and disease characteristics of 49 laparoscopic major hepatectomies (LPS group), performed between 2005 and 2015, were compared with 585 open hepatectomies (Open group) to analyze differences in patients recruitment. Factors which were found to be differently distributed between groups were used as covariates in a propensity score-based case-matched analysis with a 1:3 ratio between LPS group and 147 patients from the Open group (constituting Open-mat group). Short-term outcome was analyzed in matched groups. ASA score, previous abdominal surgery, previous interventional procedures, indication, lesion size and associated procedures were significantly different between the LPS and the Open group. Short-term outcome analysis revealed that blood loss (200 vs 350 mL, p = 0.044) and time for functional recovery (3 vs 4 days, p = 0.05) were reduced in the LPS compared to the Open-mat group, in spite of longer length of surgery (260 vs 170 min, p = 0.041) and comparable oncological adequacy. Even though data on technical feasibility of laparoscopic major resections and their benefits in terms of blood loss and functional recovery support the diffusion of minimally invasive approach, the limit of the technique is still represented by the reduced pool of suitable candidates.

- Abstract
Purpose: To investigate the short- and long-term outcomes of liver first approach (LFA) in patients with synchronous colorectal liver metastases (CRLM), evaluating the predictive factors of survival., Methods: Sixty-two out of 301 patients presenting with synchronous CRLM underwent LFA between 2007 and 2016. All patients underwent neoadjuvant chemotherapy. After neoadjuvant treatment patients were re-evaluated according to the Response Evaluation Criteria in Solid Tumors (RECIST). Liver resection was scheduled after 4-6 weeks. Changes in non-tumoral parenchyma and the tumor response according to the Tumor Regression Grade score (TRG) were assessed on surgical specimens. Primary tumor resection was scheduled 4-8 weeks following hepatectomy., Results: Five patients out of 62 (8.1%) showed "Progressive Disease" at re-evaluation after neoadjuvant chemotherapy, 22 (35.5%) showed "Stable Disease" and 35 (56.5%) "Partial Response"; of these latter, 29 (82%) showed histopathologic downstaging. The 5-year survival (OS) rate was 55%, while the 5-year disease-free survival (DFS) rate was 16%. RECIST criteria, T-stage, N-stage and TRG were independently associated with OS. Bilobar presentation of disease, RECIST criteria, R1 margin and TRG were independently associated with DFS. Patients with response to neoadjuvant chemotherapy had better survival than those with stable or progressive disease (radiological response 5-y OS: 65% vs. 50%; 5-y DFS: 20% vs. 10%; pathological response 5-y OS: 75% vs. 56%; 5-y DFS: 45% vs. 11%)., Conclusions: LFA is an oncologically safe strategy. Selection is a critical point, and the best results in terms of OS and DFS are observed in patients having radiological and pathological response to neoadjuvant chemotherapy., (Copyright © 2018 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

- 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
Diffusion of laparoscopic major hepatectomies is experiencing a steady increasing trend, although slower compared to minor resections. The aim of this single-center study is to discuss current trends and indications in the application of minimally invasive techniques to major hepatic resections. Preoperative patients and disease characteristics of 49 laparoscopic major hepatectomies (LPS group), performed between 2005 and 2015, were compared with 585 open hepatectomies (Open group) to analyze differences in patients recruitment. Factors which were found to be differently distributed between groups were used as covariates in a propensity score-based case-matched analysis with a 1:3 ratio between LPS group and 147 patients from the Open group (constituting Open-mat group). Short-term outcome was analyzed in matched groups. ASA score, previous abdominal surgery, previous interventional procedures, indication, lesion size and associated procedures were significantly different between the LPS and the Open group. Short-term outcome analysis revealed that blood loss (200 vs 350 mL, p = 0.044) and time for functional recovery (3 vs 4 days, p = 0.05) were reduced in the LPS compared to the Open-mat group, in spite of longer length of surgery (260 vs 170 min, p = 0.041) and comparable oncological adequacy. Even though data on technical feasibility of laparoscopic major resections and their benefits in terms of blood loss and functional recovery support the diffusion of minimally invasive approach, the limit of the technique is still represented by the reduced pool of suitable candidates.
