    Abstract Background: Although early series focused on benign disease, minimally invasive pancreatoduodenectomy (MIPD) might be particularly suited for malignancy. Unlike their predecessors, fellowship-trained (FT) Hepatic-Pancreatic and Biliary (HPB) surgeons usually have equal skills in approaching peri-ampullary tumors (PT) either openly or via minimally invasive (MI) techniques.
    Method: We retrospectively reviewed a MI-HPB-FT surgeon's 10-year experience with PD. A sub-analysis of malignant PT was also done (MIPD-PT vs. OPD-PT). The primary endpoint was to assess postoperative mortality and morbidity. Secondary endpoints included operative parameters, length of hospital stay, and survival analysis. Moreover, we addressed practice pattern changes for a surgeon straight out of training with no previous experience of independent surgery.
    Results: From December 2007-February 2018, one MI-HPB-FT performed a total of 100 PDs, including 57 MIPDs and 43 open PDs (OPDs). In both groups, over 70% of PDs were undertaken for malignancy. Eight patients with borderline resectable pancreatic ductal cancer (PDC) were in the OPD-PT group (as compared to only 2 in the MIPD-PT group) (p = 0.07). Estimated mean blood loss and length of stay were less in the MIPD-PT group (345 mL and 12 days) as compared to the OPD-PT group (971 mL and 16 days), p < 0.001 and p = 0.007, respectively. However, the mean operative time was longer for the MIPD-PT (456 min) as compared to the OPD-PT (371 min), p < 0.001. Thirty and 90-day mortality was 2.6%/5.1% after MIPD-PT compared to 0%/3.2% after OPD-PT, respectively, p = 1. Overall 30-/90-day morbidity rates were similar at 41.0%/43.6% after MIPD-PT and 35.5%/41.9% after OPD-PT, respectively, p = 0.8 and 1. Complete resection (R0) rates were not statistically different, 97.4% after MIPD-PT compared to 87.0% after OPD-PT (p = 0.2). After MIPD and OPD for malignant PT, overall 1, 3 and 5-year survival rates, and median survival were 82.5%, 59.6% and 46.3% and 38 months as compared to 52.5%, 15.7% and 10.5% and 13 months, respectively (p = 0.01). In the MIDP-PT group, recurrence free survival (RFS) at 1, 3 and 5 years and median RFS were 69.1%, 41.9% and 33.5% and 26 months as compared to 50.4%, 6.3% and 6.3% and 13 months, in the OPD-PT group, respectively (p = 0.03).
    Conclusion: FT HPB Surgeons who begin their practice with the ability to do both MI and OPD may preferentially approach resectable peri-ampullary tumors minimally invasively. This may result in decreased blood loss decreased length of hospital stays. Despite longer operative time, the improved visualization of MI techniques may enable superior R0 rates when compared to historical open controls. Moreover, combined with quicker initiation of adjuvant chemotherapeutic treatments, this may eventually result in improved survival.

    Abstract Background: The 8th edition of AJCC TNM staging of Gallbladder cancer subdivided T2 stage into T2a and T2b based on tumour location. This meta-analysis aimed to investigate the long-term outcomes in T2a and T2b gallbladder cancers.
    Methods: Literature search of Medline, Web of science, Embase and Cochrane databases was performed. Study characteristics, survival and recurrence data were extracted for meta-analysis of effect estimates and of individual patient data.
    Results: Fifteen retrospective studies (2531 patients, T2a = 1332, T2b = 199) were included in the meta-analysis. Overall survival (OS) was significantly worse in patients with T2b compared to T2a tumours (HR 2.18, 95% CI 1.67-2.86, p < 0.0001). Meta-analysis of individual patient data (n = 629) showed similar results (HR 1.92, 95% CI 1.43-2.58, p < 0.00001). Patients with T2b tumours had higher risk of recurrence compared to T2a (OR 3.19, 95% CI 1.40-7.28, p = 0.006) and were more likely to receive adjuvant chemotherapy (OR 1.76, 95% CI 1.12-2.84, p = 0.014). Liver resection improved OS in T2b tumours (HR 2.99, CI 1.73-5.16, p < 0.0001).
    Conclusion: T2b gallbladder tumours have worse overall survival and increase risk of recurrence compared to T2a. Liver resection appears to improve OS in patients with T2b tumours. However, high quality multicenter data is required to confirm these results.

    Abstract Aim: We aimed to evaluate the knowledge, attitude, and practices in the application of AI in the emergency setting among international acute care and emergency surgeons.
    Methods: An online questionnaire composed of 30 multiple choice and open-ended questions was sent to the members of the World Society of Emergency Surgery between 29th May and 28th August 2021. The questionnaire was developed by a panel of 11 international experts and approved by the WSES steering committee.
    Results: 200 participants answered the survey, 32 were females (16%). 172 (86%) surgeons thought that AI will improve acute care surgery. Fifty surgeons (25%) were trained, robotic surgeons and can perform it. Only 19 (9.5%) were currently performing it. 126 (63%) surgeons do not have a robotic system in their institution, and for those who have it, it was mainly used for elective surgery. Only 100 surgeons (50%) were able to define different AI terminology. Participants thought that AI is useful to support training and education (61.5%), perioperative decision making (59.5%), and surgical vision (53%) in emergency surgery. There was no statistically significant difference between males and females in ability, interest in training or expectations of AI (p values 0.91, 0.82, and 0.28, respectively, Mann-Whitney U test). Ability was significantly correlated with interest and expectations (p < 0.0001 Pearson rank correlation, rho 0.42 and 0.47, respectively) but not with experience (p = 0.9, rho - 0.01).
    Conclusions: The implementation of artificial intelligence in the emergency and trauma setting is still in an early phase. The support of emergency and trauma surgeons is essential for the progress of AI in their setting which can be augmented by proper research and training programs in this area.

    Abstract Objective: To assess the feasibility, proficiency, and mastery learning curves for robotic pancreatoduodenectomy (RPD) in "second-generation" RPD centers following a multicenter training program adhering to the IDEAL framework.
    Background: The long learning curves for RPD reported from "pioneering" expert centers may discourage centers interested in starting an RPD program. However, the feasibility, proficiency, and mastery learning curves may be shorter in "second-generation" centers that participated in dedicated RPD training programs, although data are lacking. We report on the learning curves for RPD in "second-generation" centers trained in a dedicated nationwide program.
    Methods: Post hoc analysis of all consecutive patients undergoing RPD in 7 centers that participated in the LAELAPS-3 training program, each with a minimum annual volume of 50 pancreatoduodenectomies, using the mandatory Dutch Pancreatic Cancer Audit (March 2016-December 2021). Cumulative sum analysis determined cutoffs for the 3 learning curves: operative time for the feasibility (1) risk-adjusted major complication (Clavien-Dindo grade ≥III) for the proficiency, (2) and textbook outcome for the mastery, (3) learning curve. Outcomes before and after the cutoffs were compared for the proficiency and mastery learning curves. A survey was used to assess changes in practice and the most valued "lessons learned."
    Results: Overall, 635 RPD were performed by 17 trained surgeons, with a conversion rate of 6.6% (n=42). The median annual volume of RPD per center was 22.5±6.8. From 2016 to 2021, the nationwide annual use of RPD increased from 0% to 23% whereas the use of laparoscopic pancreatoduodenectomy decreased from 15% to 0%. The rate of major complications was 36.9% (n=234), surgical site infection 6.3% (n=40), postoperative pancreatic fistula (grade B/C) 26.9% (n=171), and 30-day/in-hospital mortality 3.5% (n=22). Cutoffs for the feasibility, proficiency, and mastery learning curves were reached at 15, 62, and 84 RPD. Major morbidity and 30-day/in-hospital mortality did not differ significantly before and after the cutoffs for the proficiency and mastery learning curves. Previous experience in laparoscopic pancreatoduodenectomy shortened the feasibility (-12 RPDs, -44%), proficiency (-32 RPDs, -34%), and mastery phase learning curve (-34 RPDs, -23%), but did not improve clinical outcome.
    Conclusions: The feasibility, proficiency, and mastery learning curves for RPD at 15, 62, and 84 procedures in "second-generation" centers after a multicenter training program were considerably shorter than previously reported from "pioneering" expert centers. The learning curve cutoffs and prior laparoscopic experience did not impact major morbidity and mortality. These findings demonstrate the safety and value of a nationwide training program for RPD in centers with sufficient volume.

    Abstract Background: Despite the rapid advances that minimally invasive liver resection has gained in recent decades, open conversion is still inevitable in some circumstances. In this study, we aimed to determine the risk factors for open conversion after minimally invasive left lateral sectionectomy, and its impact on perioperative outcomes.
    Methods: This is a post hoc analysis of 2,445 of 2,678 patients who underwent minimally invasive left lateral sectionectomy at 45 international centers between 2004 and 2020. Factors related to open conversion were analyzed via univariate and multivariate analyses. One-to-one propensity score matching was used to analyze outcomes after open conversion versus non-converted cases.
    Results: The open conversion rate was 69/2,445 (2.8%). On multivariate analyses, male gender (3.6% vs 1.8%, P = .011), presence of clinically significant portal hypertension (6.1% vs 2.6%, P = .009), and larger tumor size (50 mm vs 32 mm, P < .001) were identified as independent factors associated with open conversion. The most common reason for conversion was bleeding in 27/69 (39.1%) of cases. After propensity score matching (65 open conversion vs 65 completed via minimally invasive liver resection), the open conversion group was associated with increased operation time, blood transfusion rate, blood loss, and postoperative stay compared with cases completed via the minimally invasive approach.
    Conclusion: Male sex, portal hypertension, and larger tumor size were predictive factors of open conversion after minimally invasive left lateral sectionectomy. Open conversion was associated with inferior perioperative outcomes compared with non-converted cases.

    Abstract Background: Pancreatic cancer (PC) associated diabetes mellitus (DM) might be consequent to the diabetogenic effects of tumour products, possibly acting via nitric oxide (NO). Our aims were: (1) to verify whether PC associated DM determines an increased hepatic NO and (2) using MALDI-TOF analysis, to evaluate the peptide composition of PC cell conditioned media (CM) and of portal sera from patients with PC with (n=7) or without (n=4) DM.
    Methods: In liver tissue homogenates of 23 patients with PC (n=17) or chronic pancreatitis (n=6) GAPDH mRNA and activity, glucose, lactate, nitrite and nitrate were assayed. MALDI-TOF analysis was performed in three PC cell lines CM, and in portal sera from patients with PC.
    Results: Higher GAPDH mRNA and nitrite were found in patients with than in patients without DM. In PC cell CM, only 9 among a total of 75 fragments identified, were tumour specific. One hundred seventy-three fragments were identified in the portal sera of patients: one was positively and six fragments were negatively correlated with DM.
    Conclusions: Unlike liver GAPDH, NO appears to be involved in PC associated DM. In portal sera, the absence, rather than the presence, of specific fragments, appears to be correlated with the development of DM.
