Purpose: When performing laparoscopic spleen-preserving distal pancreatectomy (LSPDP), sometimes, anatomically challenging patients are encountered, where the pancreatic tail is deep in the splenic hilum. The purpose of this study was to discuss the experience with the surgical technique of leaving the deep pancreatic tail of the splenic hilum in these patients.
Methods: Eleven patients who underwent LSPDP with remnant pancreatic tails between November 2019 and August 2021 at Samsung Medical Center in Seoul, Korea were included in the study. Their short-term postoperative outcomes were analyzed retrospectively.
Results: The mean operative time was 168.6 ± 26.0 minutes, the estimated blood loss was 172.7 ± 95.8 mL, and the postoperative length of stay was 6.1 ± 1.0 days. All 11 lesions were in the body or tail of the pancreas and included 2 intraductal papillary mucinous neoplasms, 6 neuroendocrine tumors, 2 cystic neoplasms, and 1 patient with chronic pancreatitis. In 10 of the 11 patients, only the pancreatic tail was left inside the distal portion of the splenic hilum of the branching splenic vessel, and there was a collection of intraabdominal fluid, which was naturally resolved. One patient with a remnant pancreatic tail above the hilar vessels was readmitted due to a postoperative pancreatic fistula with fever and underwent internal drainage.
Conclusion: In spleen preservation, leaving a small pancreatic tail inside the splenic hilum is feasible and more beneficial to the patient than performing splenectomy in anatomically challenging patients.
