Jejunum Patch Technique During Robot-Assisted Central Pancreatectomy: A Lesson from Open Procedure Experience

Background Central pancreatectomy (CP) has been established as the most common type of parenchyma-sparing pancreatectomy; 1 however, CP is associated with higher morbidity and a higher pancreatic fistula (PF) rate than distal pancreatectomy or pancreaticoduodenectomy. 2 , 3 The jejunum patch technique (JPT) for distal pancreatectomy has recently been applied, which efficiently decreases the incidence of PF. 4 We have adapted this technique to CP as well as distal pancreatectomy with celiac axis resection. 5 Here, we retrospectively evaluated the usefulness of JPT for open CP cases, and report the experience of robot-assisted CP using the JPT. Methods Among 37 consecutive cases who underwent CP at our institution between 2011 and 2022, clinical characteristics and postoperative short-term outcomes were compared between patients who underwent CP with and without the JPT. In robot-assisted CP using the JPT, after resection of the middle of the pancreas the transected jejunum was elevated through the retrocolic route in a Roux-en-Y fashion. The pancreatic stump was covered by the JPT using a modified Blumgart technique, following pancreaticojejunostomy for the distal side. 6 Results Among the entire cohort, 19 patients underwent CP using the JPT. The clinically relevant PF rate of the JPT group was significantly lower (47.4%) than the no-JPT group (83.3%, p = 0.022), and the length of drainage and hospital stay were shorter in the JPT group ( p = 0.010 and p = 0.017, respectively). The blood loss of robot-assisted CP using the JPT was 20 mL, and the JPT took only 15 min. Conclusion Robot-assisted CP using the JPT is an easy-to-use and promising procedure, based on experience and outcomes from open surgery.
