The outcome of laparoscopic pancreatoduodenectomy is improved with patient selection and the learning curve

International audienceBackground In our first experience, laparoscopic pancreatoduodenectomy (LPD) was associated with higher morbidity than open PD. Since, the surgical technique has been improved and LPD was avoided in some patients at very high risk of postoperative pancreatic fistula (POPF). We provide our most recent results. Method Between 2011 and 2018, 130 LPD were performed and divided into 3 consecutive periods based on CUSUM analysis and compared: first period (n = 43), second period (n = 43), and third period (n = 44). Results In the third period of this study, LPD was more frequently performed in women (46%, 39%, 59%, p = 0.21) on dilated Wirsung duct > 3 mm (40%, 44%, 57%; p = 0.54). Intraductal papillary mucinous neoplasm (IPMN) became the primary indication (12%, 39%, 34%; p = 0.037) compared to pancreatic adenocarcinoma (35%, 16%, 16%; p = 0.004). Malignant ampulloma re-increased during the third period (30%, 9%, 20%; p = 0.052) with the amelioration of surgical technique. The operative time increased during the second period and decreased during the third period (330, 345, 270; p < 0.001) with less blood loss (300, 200, 125; p < 0.001). All complications decreased, including POPF grades B/C (44%, 28%, 20%; p = 0.017), bleeding (28%, 21%, 14%; p = 0.26), Clavien-Dindo III-IV (40%, 33%, 16%; p = 0.013), re-interventions (19%, 14%, 9%; p = 0.43), and the hospital stay (26, 19, 18; p = 0.045). Less patients with similar-sized adenocarcinoma were operated during the second period (70%, 33%, 59%; p = 0.002) with more harvested lymph nodes in the third period (21,19, 25; p = 0.031) and higher R0 resection (70%, 79%, 84%; p = 0.5). On multivariate analysis the protective factors against POPF of grades B/C were pancreatic adenocarcinoma and invasive IPMN, BMI < 22.5 kg/m(2), and patients operated in the third period. Conclusion This study showed that the outcome of LPD significantly improves with the learning curve and patient selection. For safe implementation and during the early learning period, LPD should be indicated in patients at lower risk of POPF

Tumeur pseudo papillaire et solide du pancréas

Les tumeurs pseudopapillaires et solides du pancréas (TPPS) sont des tumeurs épithéliales rares. Dans la plupart des cas, il s’agit de tumeurs survenant chez la femme jeune dans la deuxième ou la troisième décennie de la vie. La survie après résection primaire approche 90% à 5 ans. Nous rapportons le cas d’une jeune patiente de la vingtaine qui présente une tumeur pseudopapillaire et solide du pancréas découverte devant des douleurs abdominales sans perturbations des bilans biologiques. La tomodensitométrie (TDM), l'imagerie par résonance magnétique (IRM) et l'échographie endoscopique ont révélé une masse bien limitée se développant au dépend de l'isthme pancréatique. L'exérèse complète de la tumeur a été réalisée. L’examen anatomopathologique confirmait le diagnostic de tumeur pseudopapillaire et solide du pancréas. En conclusion, les tumeurs pseudopapillaires et solides du pancréas doivent être évoquées comme un des diagnostics différentiels de toute masse pancréatique en particulier chez les jeunes femmes. L'exérèse chirurgicale procure un bon pronostic

Short-Term Outcomes After Spleen-Preserving Minimally Invasive Distal Pancreatectomy With or Without Preservation of Splenic Vessels

Objective: To compare short-term clinical outcomes after Kimura and Warshaw minimally invasive distal pancreatectomy (MIDP). Background: Spleen preservation during distal pancreatectomy can be achieved by either preservation (Kimura) or resection (Warshaw) of the splenic vessels. Multicenter studies reporting outcomes of Kimura and Warshaw spleen-preserving MIDP are scarce. Methods: Multicenter retrospective study including consecutive MIDP procedures intended to be spleen-preserving from 29 high-volume centers (≥15 distal pancreatectomies annually) in eight European countries. Primary outcomes were secondary splenectomy for ischemia and major (Clavien-Dindo grade ≥III) complications. Sensitivity analysis assessed the impact of excluding ('rescue') Warshaw procedures which were performed in centers that typically (&gt;75%) performed Kimura MIDP. Results: Overall, 1095 patients after MIDP were included with successful splenic preservation in 878 patients (80%), including 634 Kimura and 244 Warshaw procedures. Rates of clinically relevant splenic ischemia (0.6% vs. 1.6%, p = 0.127) and major complications (11.5% vs 14.4%, p = 0.308) did not differ significantly between Kimura and Warshaw MIDP, respectively. Mortality rates were higher after Warshaw MIDP (0.0% vs. 1.2%, p = 0.023), and decreased in the sensitivity analysis (0.0% vs 0.6%, p = 0.052). Kimura MIDP was associated with longer operative time (202 vs 184 min, p = 0.033) and less blood loss (100 vs 150 ml, p &lt; 0.001) as compared to Warshaw MIDP. Unplanned splenectomy was associated with a higher conversion rate (20.7% vs 5.0%, p &lt; 0.001). Conclusion: Kimura and Warshaw spleen-preserving MIDP provide equivalent short-term outcomes with low rates of secondary splenectomy and postoperative morbidity. Further analyses of long-term outcomes are needed
