RESUMO
BACKGROUND: Malignant Gastric Outlet Obstruction (mGOO) has been standardly treated by surgical Gastrojejunostomy (S-GJ) or Endoscopic Stenting (ES). Recently, EUS-Gastrojejunostomy (EUS-GJ) has emerged as an alternative, despite its worldwide diffusion is heterogeneous. The aim of this survey was to assess clinical decision-making around mGOO and to explore current opinions regarding EUS-GJ. METHODS: An online survey, spread through social networks and EPC newsletter, was created exploring opinions regarding indications, contraindications, benefits/risks, availability of mGOO treatments; 2 case vignettes explored clinical decision-making in different scenarios. RESULTS: Overall, 290 pancreatologists from 44 countries responded, of whom 35% surgeons and 65% gastroenterologists. The most common treatment for mGOO was ES (86%), followed by laparoscopic GJ (76%). EUS-GJ was accessible to 59% of respondents, with 10% proficient in this technique. Gold-standard treatment for mGOO varied by specialty; 45% of gastroenterologists preferred ES, 20% EUS-GJ, and 10% surgical GJ, while among surgeons, these were 24%, 8%, and 25%, respectively. A higher annual volume of mGOO treated correlated with increased EUS-GJ adoption and reduced surgical advice. For 51%, EUS-GJ will become the primary treatment for mGOO, notably higher among gastroenterologists and high-volume centers. For 14%, EUS-GJ spread will be limited in the future, or used only when ES fails (19%). Life expectancy, disease stage and patient's frailty are the main decision driver in therapeutic choice, whereas future surgical resectability does not contraindicate any treatment for 75%. EUS-GJ's main advantages were its minimally invasive nature and clinical efficacy, offset by its steep learning curve. CONCLUSIONS: This survey revealed significant differences in the management of mGOO, depending on specialties, local expertise and treatment volume, suggesting the lack of standardized algorithms. Life expectancy and patients' frailty are the main decision drivers. Regarding EUS-GJ, its availability remains suboptimal, with learning curve as the main perceived barrier.

PURPOSES: A floppy Nissen fundoplication with valve calibration (FNF-VC) performed by laparotomy has been described, to reduce postoperative dysphagia and gas bloating after 360°-fundoplication. As laparoscopy is the gold standard for fundoplication, this study reports the first results of a modified FNF-VC adapted for laparoscopy (LFNF). METHODS: Seventy-two consecutive patients, who underwent LFNF for refractory GERD between 2012 and 2021, were included. Postoperative outcomes and quality of life (QoL) by GERSS, GERD-HRQL, and GIQLI scores before and after surgery were assessed. RESULTS: The main symptoms were pyrosis (81%), regurgitation (39%), Ear-Nose-Throat symptoms (22%), and thoracic pain (24%). Hiatal hernia was present in 85% (n = 61) of the patients. There was no postoperative mortality, and the severe postoperative morbidity rate (Dindo-Clavien ≥ III) was 6%. After a median follow-up of 3.6 years, only 8% of patients were still taking proton-pump inhibitors. Long-term residual dysphagia was noted in 15% of the patients, but none required reoperation or interventional endoscopic procedures. QoL improved, with a significant reduction in GERSS and GERD-HRQL scores and a postoperative GIQLI of 101.75 (75-117.5). CONCLUSION: This series reports the safety and efficacy of an FNF-VC adapted for laparoscopy to treat GERD with a limited rate of residual dysphagia.

OBJECTIVE: To develop a prediction model for major morbidity and endocrine dysfunction after CP which could help in tailoring the use of this procedure. SUMMARY BACKGROUND DATA: Central pancreatectomy (CP) is a parenchyma-sparing alternative to distal pancreatectomy for symptomatic benign and pre-malignant tumors in body and neck of the pancreas CP lowers the risk of new-onset diabetes and exocrine pancreatic insufficiency compared to distal pancreatectomy but it is thought to increase the risk of short-term complications including postoperative pancreatic fistula (POPF). METHODS: International multicenter retrospective cohort study including patients from 51 centers in 19 countries (2010-2021). Primary endpoint was major morbidity. Secondary endpoints included POPF grade B/C, endocrine dysfunction, and the use of pancreatic enzymes. Two risk model were designed for major morbidity and endocrine dysfunction utilizing multivariable logistic regression and internal and external validation. RESULTS: 838 patients after CP were included (301 (36%) minimally invasive) and major morbidity occurred in 248 (30%) patients, POPF B/C in 365 (44%), and 30-day mortality in 4 (1%). Endocrine dysfunction in 91 patients (11%) and use of pancreatic enzymes in 108 (12%). The risk model for major morbidity included male sex, age, BMI, and ASA score≥3. The model performed acceptable with an area under curve (AUC) of 0.72(CI:0.68-0.76). The risk model for endocrine dysfunction included higher BMI and male sex and performed well (AUC:0.83 (CI:0.77-0.89)). CONCLUSIONS: The proposed risk models help in tailoring the use of CP in patients with symptomatic benign and premalignant lesions in the body and neck of the pancreas and are readily available via www.pancreascalculator.com.
RESUMO
BACKGROUND: It is unclear whether preoperative biliary drainage (PBD) by endoscopic retrograde cholangiopancreatography (ERCP) is equivalent to electrocautery-enhanced lumen-apposing metal stent (ECE-LAMS) before pancreatoduodenectomy (PD). METHODS: Patients who underwent PBD for distal malignant biliary obstruction (DMBO) followed by PD were retrospectively included in nine expert centers between 2015 and 2022. ERCP or endoscopic ultrasound-guided choledochoduodenostomy with ECE-LAMS were performed. In intent-to-treat analysis, patients drained with ECE-LAMS were considered the study group (first-LAMS group) and those drained with conventional transpapillary stent the control group (first-cannulation group). The rates of technical success, clinical success, drainage-related complications, surgical complications, and oncological outcomes were analyzed. RESULTS: Among 156 patients, 128 underwent ERCP and 28 ECE-LAMS in first intent. The technical and clinical success rates were 83.5% and 70.2% in the first-cannulation group versus 100% and 89.3% in the first-LAMS group (p = 0.02 and p = 0.05, respectively). The overall complication rate over the entire patient journey was 93.7% in first-cannulation group versus 92.0% in first-LAMS group (p = 0.04). The overall endoscopic complication rate was 30.5% in first-cannulation group versus 17.9% in first-LAMS group (p = 0.25). The overall complication rate after PD was higher in the first-cannulation group than in the first-LAMS group (92.2% versus 75.0%, p = 0.016). Overall survival and progression-free survival did not differ between the groups. CONCLUSIONS: PBD with ECE-LAMS is easier to deploy and more efficient than ERCP in patients with DMBO. It is associated with less surgical complications after pancreatoduodenectomy without compromising the oncological outcome.

INTRODUCTION: Ampullary neuroendocrine neoplasia (NEN) is rare and evidence regarding their management is scarce. This study aimed to describe clinicopathological features, management, and prognosis of ampullary NEN according to their endoscopic or surgical management. METHODS: From a multi-institutional international database, patients treated with either endoscopic papillectomy (EP), transduodenal surgical ampullectomy (TSA), or pancreaticoduodenectomy (PD) for ampullary NEN were included. Clinical features, post-procedure complications, and recurrences were assessed. RESULTS: 65 patients were included, 20 (30.8%) treated with EP, 19 (29.2%) with TSA, and 26 (40%) with PD. Patients were mostly asymptomatic (n = 46; 70.8%). Median tumor size was 17 mm (12-22), tumors were mostly grade 1 (70.8%) and pT2 (55.4%). Two (10%) EP resulted in severe American Society for Gastrointestinal Enterology (ASGE) adverse post-procedure complications and 10 (50%) were R0. Clavien 3-5 complications did not occur after TSA and in 4, including 1 postoperative death (15.4%) of patients after PD, with 17 (89.5%) and 26 R0 resection (100%), respectively. The pN1/2 rate was 51.9% (n = 14) after PD. Tumor size larger than 1 cm (i.e., pT stage >1) was a predictor for R1 resection (p < 0.001). Three-year overall survival and disease-free survival after EP, TSA, and PD were 92%, 68%, 92% and 92%, 85%, 73%, respectively. CONCLUSION: Management of ampullary NEN is challenging. EP should not be performed in lesions larger than 1 cm or with a endoscopic ultrasonography T stage beyond T1. Local resection by TSA seems safe and feasible for lesions without nodal involvement. PD should be preferred for larger ampullary NEN at risk of nodal metastasis.

AIM: A stoma exposes patients to several complications which could impair their quality of life (QoL). In the last decade, the market for stoma therapy in France has evolved, with a significant increase in the activities of home health providers, meeting a need for patient follow-up and companionship. International studies have demonstrated the impact of the stoma therapist (ST) follow-up on the improvement of an ostomy patient's QoL. However, the impact of home stoma nurse management has not been analysed. In this context we would like to assess the added value on health-related QoL from the enhanced follow-up of ostomy patients by STs. METHODS: This is a randomized, controlled, open, national and multicentre trial (12 centres) which includes patients with an ostomy who benefit from either standard follow-up or from an enhanced and personalized follow-up with, in particular, regular consultations with an ST after discharge. The primary end-point is the 3-month QoL score obtained from the Stoma-QoL questionnaire. The secondary end-points are satisfaction of the care, comparison of QoL scores (Stoma-QoL and EuroQuol EQ-5D) and the economic gains by calculating the consumption of resources between the two arms. There will be a modified intention-to-treat analysis with 6-month follow-up in both study arms. DISCUSSION: The StomaCare trial will be the first randomized controlled study in France to evaluate the impact on QoL of an enhanced follow-up at home of ostomy patients by an ST.

AIM: C-reactive protein (CRP) is a common biomarker of inflammation which has largely been used to predict the risk of postoperative septic complications after colorectal surgery. However, no data exist concerning its potential benefit after ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC). The aim of this study was to evaluate a CRP-driven monitoring discharge strategy after laparoscopic IPAA for UC. METHODS: Since 2012, 158 patients undergoing a laparoscopic IPAA for UC have been included: 66 patients (CRP group) operated since 2016 had a CRP-driven monitoring discharge on postoperative day 5 (POD 5) and were discharged on POD 6 if CRP < 100 mg/L; these patients were matched (according to age, gender, body mass index, IPAA in two or three steps) to 92 patients operated between 2012 and 2016 without any CRP monitoring (control group). RESULTS: Median length of hospital stay was shorter in the CRP than the control group (7 vs. 9 days; P < 0.001) and discharge on POD 6 occurred more frequently in the CRP group (47% vs. 7%, P < 0.001). No difference was observed between the two groups concerning overall morbidity (P = 0.980), surgical site infection (P = 0.554), Clavien-Dindo ≥ IIIa morbidity (P = 0.523), unplanned rehospitalization (P = 0.734) and 30-day reoperation (P = 0.240). CONCLUSION: CRP-driven monitoring discharge strategy after laparoscopic IPAA for UC is associated with a significant reduction in length of hospital stay, without increasing morbidity, reoperation or rehospitalization rates.

AIM: Management of rectovaginal fistula (RVF) remains a challenge, especially in cases of postoperative RVF as they are often large and surrounded by inflammatory and fibrotic tissue, making local repair difficult or even impossible. In this situation, colonic pull-through delayed coloanal anastomosis (DCAA) could be an interesting option. The aim of this study was to assess the results of DCAA for RVF observed after rectal surgery. METHODS: All patients who underwent DCAA for RVF were reviewed. Success was defined as a patient without stoma and without any symptoms of recurrent RVF at the end of follow-up. RESULTS: From January 2010 to December 2020, 28 DCAA were performed for RVF after rectal surgery for rectal cancer (n = 21) or endometriosis (n = 7). Ten patients (36%) had at least one previous local procedure before DCAA. DCAA was associated with temporary ileostomy in 22/28 cases (79%). After a mean follow-up of 23 ± 23 (2-82) months, the success rate was 86% (24/28): three patients (11%) required a definitive stoma because of poor functional results (n = 1), chronic pelvic sepsis with anastomotic leakage (n = 1) or stoma reversal refused (n = 1). Another patient (3%) presented with recurrence of RVF, 26 months after DCAA. Although not significant, the success rate was higher in cases of DCAA with diverting stoma (20/22, 91%) than without (4/6, 67%) (p = 0.191). CONCLUSION: In cases of postoperative RVF, DCAA is a safe option which can avoid definitive stoma in the great majority of the patients. Concomitant use of a temporary stoma appears to slightly increase the success rate.

OBJECTIVE: The aim of this study was to define robust benchmark values for the surgical treatment of perihilar cholangiocarcinomas (PHC) to enable unbiased comparisons. BACKGROUND: Despite ongoing efforts, postoperative mortality and morbidity remains high after complex liver surgery for PHC. Benchmark data of best achievable results in surgical PHC treatment are however still lacking. METHODS: This study analyzed consecutive patients undergoing major liver surgery for PHC in 24 high-volume centers in 3 continents over the recent 5-year period (2014-2018) with a minimum follow-up of 1âyear in each patient. Benchmark patients were those operated at high-volume centers (≥50 cases during the study period) without the need for vascular reconstruction due to tumor invasion, or the presence of significant co-morbidities such as severe obesity (body mass index ≥35), diabetes, or cardiovascular diseases. Benchmark cutoff values were derived from the 75th or 25th percentile of the median values of all benchmark centers. RESULTS: Seven hundred eight (39%) of a total of 1829 consecutive patients qualified as benchmark cases. Benchmark cut-offs included: R0 resection ≥57%, postoperative liver failure (International Study Group of Liver Surgery): ≤35%; in-hospital and 3-month mortality rates ≤8% and ≤13%, respectively; 3-month grade 3 complications and the CCI: ≤70% and ≤30.5, respectively; bile leak-rate: ≤47% and 5-year overall survival of ≥39.7%. Centers operating mostly on complex cases disclosed better outcome including lower post-operative liver failure rates (4% vs 13%; P = 0.002). Centers from Asia disclosed better outcomes. CONCLUSION: Surgery for PHC remains associated with high morbidity and mortality with now the availability of benchmark values covering 21 outcome parameters, which may serve as key references for comparison in any future analyses of individuals, group of patients or centers.

OBJECTIVE: To report the 90-day mortality benefit associated with the implementation of the new regulatory reform on oncological surgical digestive authorizations. SUMMARY BACKGROUND DATA: New thresholds in digestive cancer surgery were applied in 2023, accrediting centers for major interventions. No evidence has been provided to support their justification. METHODS: Any French adult operated for digestive cancer from January 1, 2019 to December 31, 2021 was included from the PMSI. A 90-day mortality logistic regression was performed by adjusting by age, sex, Charlson score, Frailty index, hospital-volume (<5 or ≥5 interventions/year), emergency intervention, specialty. RESULTS: 143,582 patients were identified. Of these, 64,268 underwent surgery of one of the subspecialties subject to the new thresholds (stomach N = 8283, liver N = 18,668, pancreas N = 11,220, esophagus N = 3704, rectum N = 22,393). 4808 (7.5 %) patients underwent surgery in low-volume centers, distributed as follows: stomach 1757/8283 (22.94 %), liver 970/18,668 (5.19 %), pancreas 895/11,220 (7.98 %), esophagus 672/3704 (18.14 %) and rectum 514/22,393 (2.29 %). In univariate analysis, the 90-day mortality rate was significantly lower in high-volume centers, for all subspecialties, gastric: 127/1757 (7.23 %) vs 330/6526 (5.06 %), p = 0.0004, hepatic: 64/970 (6.6 %) vs 824/17,698 (4.66 %), p = 0.006, pancreatic: 74/895 (8, 27 %) vs 608/10,325 (5.89 %), p = 0.004, esophageal: 58/672 (8.63 %) vs 195/3032 (6.43 %), p = 0.04, rectal 26/514 (5.06 %) vs 639/21,879 (2.92 %), p = 0.005. The multivariate analysis, showed a mortality reduction for high-volume centers: OR = 0.78 CI95[0.71-0.87], p < 0.001. CONCLUSION: The recent implementation of regulatory decrees appears to be justified. The enforcement of these hospital volume thresholds is likely to contribute to a reduction in postoperative mortality following digestive cancer surgery.

BACKGROUND: Lymph node dissection improves adrenocortical carcinoma staging, but remains anatomically poorly defined. This ambiguity stems from limited knowledge of the adrenals lymphatic network. This work aims to define lymph node dissection for adrenocortical carcinoma through a systematic review and anatomical study. METHOD: First, an anatomical study was conducted on fresh cadavers by injecting blue dye into each adrenal gland before dissection. Concurrently, a systematic review of anatomical and clinical studies was performed, focusing on adrenals lymphatic network, lymph node dissection, and location of invaded lymph nodes in surgical series. RESULTS: Twelve adrenals from 6 cadavers were resected en bloc with a median of 3 lymph nodes (1.5-6) removed. Screening of 6,506 studies revealed (1) 18 anatomical studies on cadavers detailing a 3-stage compartmentalized adrenals lymphatic network with distinct right/left lymph nodes relays; (2) 4 clinical studies highlighting discrepancies in lymph node involvement in adrenocortical carcinoma patients compared with anatomical description of adrenals lymphatic network, notably: lower implication of celiac lymph node, preponderance of ipsilateral renal hilum lymph nodes, potential contralateral involvement; (3) 21 series of adrenocortical carcinoma surgery demonstrating the heterogeneity of lymph node dissection practice (22% ± 4% lymph node dissection rate), with an average of 2.7 ± 0.6 lymph nodes removed, already fewer than in our cadaveric study. CONCLUSION: Synthesis of anatomical and clinical studies suggest the following lymph node dissection protocol during adrenocortical carcinoma resection: capsular, renal hilum, para-cava, and inter-aortic-cava lymph nodes (right adrenocortical carcinoma); and capsular, renal hilum, para-aortic, and inter-aortic-cava lymph nodes (left adrenocortical carcinoma).
RESUMO
BACKGROUND: E-cadherin, a major actor of cell adhesion in the intestinal barrier, is encoded by the CDH1 gene associated with susceptibility to Crohn Disease (CD) and colorectal cancer. Since epigenetic mechanisms are suspected to contribute to the multifactorial pathogenesis of CD, we studied CpG methylation at the CDH1 locus. The methylation of the CpG island (CGI) and of the 1st enhancer, two critical regulatory positions, was quantified in surgical specimens of inflamed ileal mucosa and in peripheral blood mononuclear cells (PBMC) of 21 CD patients. Sixteen patients operated on for a non-inflammatory bowel disease, although not normal controls, provided a macroscopically normal ileal mucosa and PBMC for comparison. RESULTS: In ileal mucosa, 19/21 (90%) CD patients vs 8/16 control patients (50%) (p < 0.01) had a methylated CDH1 promoter CGI. In PBMC, CD patients with methylated CGI were 11/21 (52%) vs 7/16 controls (44%), respectively. Methylation in the 1st enhancer of CDH1 was also higher in the CD group for each of the studied CpGs and for their average value (45 ± 17% in CD patients vs 36 ± 17% in controls; p < 0.001). Again, methylation was comparable in PBMC. Methylation of CGI and 1st enhancer were not correlated in mucosa or PBMC. CONCLUSIONS: Methylation of several CpGs at the CDH1 locus was increased in the inflamed ileal mucosa, not in the PBMC, of CD patients, suggesting the association of CDH1 methylation with ileal inflammation. Longitudinal studies will explore if this increased methylation is a risk marker for colorectal cancer.

Malignant gastric outlet obstruction (mGOO) is a major condition affecting patients with periampullary tumors, including pancreatic cancer. The current treatment options include surgical gastroenterostomy, endoscopic stenting and more recently EUS-guided gastroenterostomy. Most studies comparing the outcomes of the three procedures focus on technical success, clinical success and safety. Several "occult" outcomes relevant to the patient's viewpoints and perspective may ultimately impact on cancer-related and overall survival, such as body mass composition, nutritional biomarkers, chemotherapy tolerance and patient-reported quality of life. The aim of this review is to provide an overview of potential key outcomes that should be explored in future comparative research around mGOO treatment options.
RESUMO
Prophylactic lymph node dissection is considered only for papillary cancers. It is not indicated for vesicular cancers or oncocytic cancers, nor should it entail a secondary surgical intervention in the event of an incidental discovery of papillary cancer on a thyroidectomy specimen. Prophylactic lymph node dissection means a cervical lymph node dissection in the absence of any pre- or intraoperative evidence (biological, cytological, histological, clinical or ultrasound) of lymph node metastases. There is currently no evidence in the literature that prophylactic central dissection improves overall survival, which is similar for N0 and NX patients. Yet although prophylactic lymph node dissection is not justified by overall survival, it does seem to reduce the risk of locoregional recurrence in the case of micro-N1, and it allows occult metastases to be detected and a tumour to be reclassified. This enables patients at risk of recurrence to be more surely identified and therapeutic strategy and follow-up adapted accordingly. Prophylactic homolateral central lymph node dissection is warranted for papillary cancers with largest ultrasound diameter 4cm and above and/or with intraoperative macroscopic evidence of perithyroid tissue invasion. The benefits and risks of lymph node dissection must be assessed and discussed on a case-by-case basis. Only a central lymph node dissection homolateral to the tumour is recommended, except for bilateral or isthmic cancers, for which a prophylactic bilateral central lymph node dissection may be considered. This bilateral lymph node dissection incurs an increased risk of complications (parathyroids, recurrent laryngeal nerve). Prophylactic lateral lymph node dissection is not recommended.

BACKGROUND: Ampullary lesions are rare and can be locally treated either with endoscopic papillectomy or transduodenal surgical ampullectomy. Management of local recurrence after a first-line treatment has been poorly studied. METHODS: Patients with a local recurrence of an ampullary lesion initially treated with endoscopic papillectomy or transduodenal surgical ampullectomy were retrospectively included from a multi-institutional database (58 centers) between 2005 and 2018. RESULTS: A total of 103 patients were included, 21 (20.4%) treated with redo endoscopic papillectomy, 14 (13.6%) with transduodenal surgical ampullectomy, and 68 (66%) with pancreaticoduodenectomy. Redo endoscopic papillectomy had low morbidity with 4.8% (n = 1) severe to fatal complications and a R0 rate of 81% (n = 17). Transduodenal surgical ampullectomy and pancreaticoduodenectomy after a first procedure had a higher morbidity with Clavien III and more complications, respectively, 28.6% (n = 4) and 25% (n = 17); R0 resection rates were 85.7% (n = 12) and 92.6% (n = 63), both without statistically significant difference compared to endoscopic papillectomy (P = .1 and 0.2). Pancreaticoduodenectomy had 4.4% (n = 2) mortality. No deaths were registered after transduodenal surgical ampullectomy or endoscopic papillectomy. Recurrences treated with pancreaticoduodenectomy were more likely to be adenocarcinomas (79.4%, n = 54 vs 21.4%, n = 3 for transduodenal surgical ampullectomy and 4.8%, n = 1 for endoscopic papillectomy, P < .0001). Three-year overall survival and disease-free survival were comparable. CONCLUSION: Endoscopy is appropriate for noninvasive recurrences, with resection rate and survival outcomes comparable to surgery. Surgery applies more to invasive recurrences, with transduodenal surgical ampullectomy rather for carcinoma in situ and early cancers and pancreaticoduodenectomy for more advanced tumors.

BACKGROUND: The diagnosis of low potential malignant diseases is increasingly frequent, and laparoscopic central pancreatectomy can be indicated in these patients. Laparoscopic central pancreatectomy that usually preserves the splenic vessels results in a low risk of new-onset diabetes but high morbidity, mainly due to postoperative pancreatic fistula and postpancreatectomy hemorrhage. In this study, we evaluated the short and long-term complications after laparoscopic central pancreatectomy with splenic vessel resection. METHODS: This retrospective single-center cohort study included 650 laparoscopic pancreatic resections from 2008 to 2020 with 84 laparoscopic central pancreatectomy; 15 laparoscopic central pancreatectomy with splenic vessel resection; and 69 laparoscopic central pancreatectomy with preservation of the splenic vessels. Pancreaticogastrostomy was routinely performed, and the patients were discharged after complications had been treated. The 15 laparoscopic central pancreatectomy with splenic vessel resection were matched for age, sex, body mass index, and tumor characteristics [1:2] and compared with 30 laparoscopic central pancreatectomy with the preservation of the splenic vessels. RESULTS: In the laparoscopic central pancreatectomy with splenic vessel resection group, resection of splenic vessels was performed due to tumoral or inflammatory adhesions (n = 11) or accidental vascular injury (n = 4). The demographic characteristics of the groups were similar. Tumors were larger in the laparoscopic central pancreatectomy with splenic vessel resection group (40 vs 21 mm; P = .008), and right transection on the body of the pancreas (53% vs 13%; P = .01) was more frequent. There were no differences in the characteristics of the pancreas (Wirsung duct size or consistency). The median operative time (minutes) was longer in the laparoscopic central pancreatectomy with splenic vessel resection group than in the laparoscopic central pancreatectomy with preservation of the splenic vessels group (210 vs 180, respectively; P = .15) with more blood loss (100 mL vs 50 mL, respectively; P = .012). The lengths (mm) of the resected pancreas and remnant distal pancreas in the 2 groups were 65 vs 50 (P = .053) and 40 vs 65 (P = .006), respectively. There were no differences in postoperative mortality (0% vs 3%; P = .47), grade B-C postoperative pancreatic fistula (27% vs 27%; P = 1), reintervention (7% vs 13%; P = .50), grade B-C postpancreatectomy hemorrhage (0% vs 13%; P = .13), length of hospital stay (20 days vs 22 days; P = .15), or new-onset diabetes (7% vs 10%; P = .67) between the 2 groups. CONCLUSION: Laparoscopic central pancreatectomy with splenic vessel resection is a safe technical modification of central pancreatectomy that does not prevent preservation of the distal pancreas and does not influence postoperative pancreatic fistula or endocrine insufficiency. Furthermore, it could reduce the risk of postpancreatectomy hemorrhage.

Pancreatic neuroendocrine tumours (pNETs) represent 1 to 2% of all pancreatic neoplasm with an increasing incidence. They have a varied clinical, biological and radiological presentation, depending on whether they are sporadic or genetic in origin, whether they are functional or non-functional, and whether there is a single or multiple lesions. These pNETs are often diagnosed at an advanced stage with locoregional lymph nodes invasion or distant metastases. In most cases, the gold standard curative treatment is surgical resection of the pancreatic tumour, but the postoperative complications and functional consequences are not negligible. Thus, these patients should be managed in specialised high-volume centres with multidisciplinary discussion involving surgeons, oncologists, radiologists and pathologists. Innovative managements such as "watch and wait" strategies, parenchymal sparing surgery and minimally invasive approach are emerging. The correct use of all these therapeutic options requires a good selection of patients but also a constant update of knowledge. The aim of this work is to update the surgical management of pNETs and to highlight key elements in view of the recent literature.
