RESUMEN
BACKGROUND: Due to delayed diagnosis and a lower surgical indication rate, left-sided pancreatic ductal adenocarcinoma (PDAC) is often associated with a poor prognosis in comparison to pancreatic head tumors. Multi-visceral resections (MVR) associated with distal pancreatectomy could be proposed for patients presenting with locally infiltrating disease. METHODS: We retrospectively analyzed a multi-centric cohort of left-sided PDAC patients operated on from 2009 to 2020. Thirteen European high-volume HPB centers participated in this study. We analyzed patients who underwent distal pancreatectomy (DP) associated with MVR and compared them to standard DP patients. RESULTS: Among 258 patients treated curatively for PDAC of the body and tail, 28 patients successfully underwent MVR. A longer operative time was observed in the MVR group (295 min +/- 74 vs. 250 min +/- 96, p= 0.248). The post-operative complication rate was comparable between the two groups (46.4% in the MVR group vs. 62.2% in the control group, p= 0.108). The incidence of positive margin (R1) was similar between the two groups (28.6% vs. 26.6%; p=0.827). After a median follow-up of 25 (9-111) months, overall survival was comparable between the two groups (p= 0.519). CONCLUSIONS: Multi-visceral resection in left-sided pancreatic ductal adenocarcinoma is safe and feasible and should be considered in selected cases as it seems to provide acceptable surgical and oncological outcomes.

INTRODUCTION: 'Brittle Diabetes' (BD) is a life-threatening metabolic complication after total pancreatectomy (TP). More than 500 Intraportal islet autotransplantation (IAT) have been performed to prevent this complication, with almost 70% insulin independence after 3 years. Even when insulin independence was not achieved, IAT successfully prevented severe hypoglycemia. Currently, preliminary results for oncologic situations are promising, but their oncological outcomes are still a matter of debate. AREAS COVERED: We performed a bibliographic research of the last 25 years of data. Articles published in English in peer-reviewed journals were retained. In France, auto- and allo-islet transplantation was recently recognized as a valuable treatment for BD by the national health authority. While accepted for benign diseases, the risk of tumor spreading after IAT in oncologic situations is a source of concern. EXPERT OPINION: Preliminary results of IAT in oncological situations are very encouraging. So far, there is no evidence of tumor dissemination. In our opinion, to overcome BD TP with IAT for resectable pancreatic malignancies in patients with a higher risk of postoperative pancreatic fistula and extended pancreatic cancers can be safely performed. Diagnosis of malignancy should not be considered as an exclusion criterion for IAT.

Hemothorax (HT) is a life-threatening condition, mainly iatrogenic and poorly explored in Liver Transplantation (LT) recipients. The aim of this study is to report and analyze for the first time incidence and outcomes of HT in LT recipients, as well as to suggest a management strategy. Data concerning 7130 consecutive adult liver and liver-kidney transplant recipients were retrospectively collected from ten Transplantation Centers' institutional databases, over a 10-year period. Clinical parameters, management strategies and survival data about post-operative HT were analyzed and reported. Thirty patients developed HT during hospitalization (0.42%). Thoracentesis was found to be the most common cause of HT (16 patients). A non-surgical management was performed in 17 patients, while 13 patients underwent surgery. 19 patients developed thoracic complications after HT treatment, with an overall mortality rate of 50%. The median length of stay in Intensive Care Units was 22 days (IQR25-75 5-66.5). Postoperative hemothorax is mainly due to iatrogenic causes in LT recipients. Despite rare, it represents a serious complication with a high mortality rate and a challenging medical and surgical management. Its occurrence should always be prevented.

BACKGROUND: In literature, a variety of caval reconstruction techniques for liver transplantation have been reported. The piggyback technique preserves the recipient's caval vein which is directly anastomosed to donor's inferior vena cava (IVC) allowing for the reduction of hemodynamic compromise during liver transplantation. METHODS: Herein, we present our standardized step-by-step technique for the realization of a caval one-shot side-to-side anastomosis (OSSSA) using a linear stapler. A Satinsky vascular clamp is placed in a top down direction to realize a longitudinal partial clamping of the recipient IVC. A 1-cm venotomy is then performed on the anterior wall of the recipient IVC to permit the easy introduction of the vascular stapler arm in order to perform the mechanical anastomosis. Portal vein, hepatic artery, and biliary anastomosis are then completed in standard fashion. CONCLUSIONS: Compared to the manual one, this mechanical anastomosis permits to reduce operative time, caval and portal vein clamping, warm ischemia time, and visceral congestion. RESULTS: In our opinion, this is a rapid, easy, safe, and reproducible technique to perform the side-to-side cavocaval anastomosis during liver transplantation in selected patients when a manual anastomosis may be technically challenging.

OBJECTIVES: The aim of this study was to assess the impact of clinically relevant postoperative pancreatic fistula (CR-POPF) on patient disease-specific survival and recurrence after curative distal pancreatectomy (DP) for pancreatic cancer. DESIGN: This was a retrospective case-control analysis. METHODS: We examined the data of adult patients with a diagnosis of pancreatic ductal adenocarcinoma (PDAC) of the body and tail of the pancreas undergoing curative DP, over a 10-year period in 12 European surgical departments, from a prospectively implemented database. RESULTS: Among the 382 included patients, 283 met the strict inclusion criteria; 139 were males (49.1%) and the median age of the entire population was 70 years (range 37-88). A total of 121 POPFs were observed (42.8%), 42 (14.9%) of which were CR-POPFs. The median follow-up period was 24 months (range 3-120). Although poorer in the POPF group, overall survival (OS) and disease-free survival (DFS) did not differ significantly between patients with and without CR-POPF (p = 0.224 and p = 0.165, respectively). CR-POPF was not significantly associated with local or peritoneal recurrence (p = 0.559 and p = 0.302, respectively). A smaller percentage of patients benefited from adjuvant chemotherapy after POPF (76.2% vs. 83.8%), but the difference was not significant (p = 0.228). CONCLUSIONS: CR-POPF is a major complication after DP but it did not affect the postoperative therapeutic path or long-term oncologic outcomes. CR-POPF was not a predictive factor for disease recurrence and was not associated with an increased incidence of peritoneal or local relapse. TRIAL REGISTRATION: ClinicalTrials.gov ID: NCT04348084.

BACKGROUND: Short and long-term outcomes after repeat anti-reflux surgery (RARS) are still debated and generally not considered as satisfying as after primary anti-reflux surgery (PARS). The aim of this study was to evaluate functional outcomes after RARS and risk factors associated to intra-operative and post-operative complications. METHODS: This is a multicenter retrospective survey from four European laparoscopic centers. Patients who underwent elective RARS from January 2005 to October 2017 for dysphagia or for persistent reflux disease refractory to medical treatment were analyzed. Data on demographic characteristics, including type and timing of previous operations as well as intra-operative details (surgical technique, type of RARS, conversion to open surgery, prosthetic material placement) were collected. Patients who underwent operations in the emergency setting, interventions mixed with bariatric procedures and PARS performed in other surgical departments were not included in this study. Primary endpoint of this study was to evaluate risk factors associated with intraoperative and postoperative complications. Secondary endpoint was to evaluate clinical outcomes and to identify any possible correlation with clinical and surgical parameters. RESULTS: Among 1662 patients who underwent PARS, failure occurred in 174 (10.5%) patients. Repeat surgery was performed in 117 (7%) patients, after a mean time of 80 months (range 4-315). RARS was carried out laparoscopically in 88% of cases. Prosthetic mesh to reinforce hiatoplasty was used in 22.2% of patients. Intra-operative upper gastro-intestinal tract's injuries occurred in 6 (5.1%) patients. Perioperative mortality was nil and 13 (11.1%) patients experienced postoperative complications. Mean length of hospital stay was 9.6 ± 6.4 days. Based on a multivariable analysis, age >70 years (OR 1.074, C.I.95% 1.018-1.133, p = 0.008) and body mass index (BMI) < 23 (OR 0.172, C.I.95% 0.052-0.568, p = 0.004) were independently associated to postoperative complications. After a mean follow-up time of 36 months (range 6-107), 24 (20.5%) patients presented recurrent symptoms. Based on a multivariable analysis, early onset of dysphagia (OR 3.539, C.I.95% 1.254-9.990, p = 0.017), open approach (OR 4.505, C.I.95% 1.314-15.442, p = 0.016) and the use of prosthetic material (OR 2.790, C.I.95% 0.930-8.776, p = 0.047) were significantly associated to good clinical outcomes. CONCLUSIONS: Repeat anti-reflux surgery is a safe and feasible procedure in high-volume centers, with acceptable perioperative outcomes. Long-term results are favorable with a success rate of almost 80%. Advanced age (>70 years) and low BMI (<23 kg/m2) were factor predicting perioperative complications. The use of prosthesis for hiatoplasty was associated to better functional outcomes.

BACKGROUND: Microvascular invasion (MVI) has been proved to be poor prognostic factor in many cancers. To date, only one study published highlights the relationship between this factor and the natural history of pancreatic cancer. The aim of this study was to assess the impact of MVI, on disease-free survival (DFS) and overall survival (OS), after pancreatico-duodenectomy (PD) for pancreatic head adenocarcinoma. Secondarily, we aim to demonstrate that MVI is the most important factor to predict OS after surgery compared with resection margin (RM) and lymph node (LN) status. MATERIALS AND METHODS: Between January 2015 and December 2017, 158 PD were performed in two hepato-bilio-pancreatic (HBP) centers. Among these, only 79 patients fulfilled the inclusion criteria of the study. Clinical-pathological data and outcomes were retrospectively analyzed from a prospectively maintained database. RESULTS: Of the 79 patients in the cohort, MVI was identified in 35 (44.3%). In univariate analysis, MVI (P = .012 and P < .0001), RM (P = .023 and P = .021), and LN status (P < .0001 and P = .0001) were significantly associated with DFS and OS. A less than 1 mm margin clearance did not influence relapse (P = .72) or long-term survival (P = .48). LN ratio > 0.226 had a negative impact on OS (P = .044). In multivariate analysis, MVI and RM persisted as independent prognostic factors of DFS (P = .0075 and P = .0098, respectively) and OS (P < .0001 and P = .0194, respectively). Using the likelihood ratio test, MVI was identified as the best fit to predict OS after PD for ductal adenocarcinomas compared with the margin status model (R0 vs R1) (P = .0014). CONCLUSION: The MVI represents another major prognostic factor determining long-term outcomes.

BACKGROUND: The aim of this study was to analyze the clinical and economic impact of robotic distal pancreatectomy, laparoscopic distal pancreatectomy, and open distal pancreatectomy. METHODS: All consecutive patients who underwent distal pancreatic resection for benign and malignant diseases between January 2012 and December 2015 were prospectively included. Cost analysis was performed; all charges from patient admission to discharge were considered. RESULTS: There were 21 robotic (RDP), 25 laparoscopic (LDP), and 43 open (ODP) procedures. Operative time was longer in the RDP group (RDP =345 minutes, LDP =306 min, ODP =251 min, P=0.01). Blood loss was higher in the ODP group (RDP =192 mL, LDP =356 mL, ODP =573 mL, P=0.0002). Spleen preservation was more frequent in the RDP group (RDP =66.6%, LDP =61.9%, ODP =9.3%, P=0.001). The rate of patients with Clavien-Dindo > grade III was higher in the ODP group (RDP =0%, LDP =12%, ODP =23%, P=0.01), especially for non-surgical complications, which were more frequent in the ODP group (RDP =9.5%, LDP =24%, ODP =41.8%, P=0.02). Length of hospital stay was increased in the ODP group (ODP =19 days, LDP =13 days, RDP =11 days, P=0.007). The total cost of the procedure, including the surgical procedure and postoperative course was higher in the ODP group (ODP =30,929 Euros, LDP =22,150 Euros, RDP =21,219 Euros, P=0.02). CONCLUSIONS: Cost-effective results of RDP seem to be similar to LDP with some better short-term outcomes.
RESUMEN
BACKGROUND: Indocyanine green (ICG) fluorescence imaging is a promising tool for intraoperative decision-making during surgical procedures, in particular to assess organs perfusion. METHODS: We used the ICG fluorescence during liver transplantations in six cirrhotic patients to help assessing the graft biliary duct perfusion in order to identify the appropriate level to perform the anastomosis. We also used ICG fluorescence also in five patients receiving kidney-pancreas transplantation to evaluate the perfusion levels of the duodenal stump of the pancreas graft. RESULTS: Follow-up period for the patients was 12 months. The perioperative period was uneventful, no biliary complications such as leaks or stenosis were reported after liver transplantation, no complications of the entero-enteric anastomoses occurred after pancreatic transplantation. CONCLUSIONS: ICG fluorescence seems to safely provide important objectifiable perfusion information during organ transplantation procedures that can integrate surgeon's expertise. In fact, detecting intra-operatively perfusion defects, it allows real time modifications on technical strategies potentially useful to reduce the feared risk of anastomotic leakage and consequent severe complications.
RESUMEN
BACKGROUND: According to many Societies' guidelines, patients presenting with clinical T4 colorectal cancer should conventionally be approached by a laparotomy. Results of emerging series are questioning this attitude. METHODS: We retrospectively analysed the oncologic outcomes of 147 patients operated on between June 2008 and September 2015 for histologically proven pT4 colon cancers. All patients were treated with curative intent, either by a laparoscopic or open "en bloc" resection. RESULTS: Median operative time, blood loss and hospital length of stay were significantly reduced in the laparoscopic group. Postoperative surgical complication rate and 30-day mortality did not significantly differ between the two groups ( p = 0.09 and p = 0.99, respectively). R1 resection rate and lymph nodes harvest, as well, did not remarkably differ when comparing the two groups. In the laparoscopic group, conversion rate was 19%. Long-term outcomes were not affected in patients who had undergone conversion. Five-year overall survival and disease-free survival did not significantly differ between the two groups (44.6% and 40.3% vs. 39.4% and 38.9%). Locally advanced stages (IIIB-IIIC) and R1 resections were detected as independent prognostic factors for overall survival. CONCLUSION: Laparoscopic approach might be safe and acceptable for locally advanced colon cancer and does not jeopardize the oncologic results. Conversion to open surgery should be a part of a strategy as it does not seem to adversely affect perioperative and long-term outcomes. We consider laparoscopy, in expert hands, the last diagnostic tool and the first therapeutic approach for well-selected locally advanced colon cancers. Larger prospective studies are needed to widely assess this issue.

BACKGROUND: Gallstone disease affects 15-20% of the general population and up to 20% of these patients present common bile duct stones. AIM: This observational study reports our experience on routine cysticotomy and flushing of the cystic duct in patients with low risk of common duct stones. MATERIALS AND METHODS: We analyzed 731 patients who underwent laparoscopic cholecystectomy between September 2013 and September 2015. RESULTS: Patients were preoperatively stratified on the clinical risk; those presenting with low preoperative risk of common bile duct stones were referred to undergo laparoscopic cholecystectomy and routine cysticotomy with bile duct flushing. Patients presenting thick bile sludge, solid debrides, and/or increased tension of bile outflow underwent unplanned cholangiography. No intraoperative complications or conversion to open technique occurred. Average follow-up time was 22,8 months (range 12 to 37). Rate of retained ductal stones accounted for 0,3%. CONCLUSIONS: Routine cysticotomy and bile flushing in our experience is a valid, simple, and not time consuming manoeuvre that can help decompressing and flushing CBD. Moreover, it is a valid tool for extending selective IOC approach in a focused manner. Further evaluations have to be conducted to evaluate risks and effectiveness of this manoeuvre.
RESUMEN
BACKGROUND: The aim of this study is to evaluate if 3-dimensional high-definition (3D) vision in laparoscopy can prompt advantages over conventional 2D high-definition vision in hiatal hernia (HH) repair. STUDY DESIGN: Between September 2012 and September 2015, we randomized 36 patients affected by symptomatic HH to undergo surgery; 17 patients underwent 2D laparoscopic HH repair, whereas 19 patients underwent the same operation in 3D vision. RESULTS: No conversion to open surgery occurred. Overall operative time was significantly reduced in the 3D laparoscopic group compared with the 2D one (69.9 vs 90.1 minutes, P = .006). Operative time to perform laparoscopic crura closure did not differ significantly between the 2 groups. We observed a tendency to a faster crura closure in the 3D group in the subgroup of patients with mesh positioning (7.5 vs 8.9 minutes, P = .09). Nissen fundoplication was faster in the 3D group without mesh positioning ( P = .07). CONCLUSIONS: 3D vision in laparoscopic HH repair helps surgeon's visualization and seems to lead to operative time reduction. Advantages can result from the enhanced spatial perception of narrow spaces. Less operative time and more accurate surgery translate to benefit for patients and cost savings, compensating the high costs of the 3D technology. However, more data from larger series are needed to firmly assess the advantages of 3D over 2D vision in laparoscopic HH repair.
