Aim:The aim of this meta-analysis is to compare perioperative outcomes and costs of robotic and laparoscopic distal pancreatectomy (RDP and LDP). Material and methods:In accordance with the PRISMA guidelines, we searched Medline, EMBASE, Cochrane and Web of Science for reports published before December 2020. Results:The literature search identified 11 papers (1 187 patients). RDP showed a lower conversion rate (odds ratio: 2.56, 95% confidence intervals [CI]: 1.31 to 5.00) with no significant differences in bleeding and operative time, complications ≥ Clavien-Dindo grade III, pancreatic fistulas and length of stay. Despite RDP presenting higher costs in all included studies, none of these differences were significant. However, RDP showed higher total costs than LDP (standardized mean differences [SMD]: −1.18, 95% CI: −1.97 to −0.39). A subgroup analysis according to the continent of origin showed that studies coming from Asian research groups kept showing significant differences (SMD: −2.62, 95% CI: −3.38 to −1.85), while Western groups did not confirm these findings. Conclusion:Based on low-quality evidence, despite some potential technical advantages, RDP still seems to be costlier than LDP.

Cystic dystrophy of heterotopic pancreas is a rare condition that means cystic changes of normal pancreatic tissue, placed in unusual locations, commonly in the duodenal wall. We report a case of CDHP in stomach, histologically confirmed after surgery. We show the correlation between radiological and anatomopathological findings, and also review the current literature about reported cases of this exceptional disease.
