Pancreatic enucleation using the da Vinci robotic surgical system: a report of 26 cases

摘要

BACKGROUND: As a tissue-sparing procedure, pancreatic enucleation has become an alternative for benign or borderline pancreatic tumours; it has been proved to be safe and feasible. To date, a large sample size of robotic pancreatic enucleation has not been reported. This study aimed to discuss the clinical evaluation and postoperative complications after robotic pancreatic enucleation and compare it with open surgery. METHODS: Patients who underwent robotic or open pancreatic enucleation during December 2010-December 2014 at Shanghai Ruijin Hospital, affiliated with the Shanghai Jiaotong University School of Medicine in China, were included. Clinical data were collected and analysed. RESULTS: Patients were divided into an open group and a robotic group: 26 patients underwent robotic pancreatic enucleation, of whom 13 patients were female. The mean age was 51.7 years, the operation time was 125.7 ± 58.8 min, blood loss was 49.4 ± 33.4 ml and mean tumour size was 18.8 ± 7.9 mm; 17 patients underwent open pancreatic enucleation, of whom 11 were female. The mean age was 54.6 ± 17.2 min, blood loss was 198.5 ± 70.7 ml and mean tumour size was 3.5 ± 1.9 cm. Pathology included insulinomas, intrapancreatic mucinous neoplasmas (IPMNs), pancreatic neuro-endocrine tumours (PNETs), solid pseudopapillary tumours (SPTs) and serous cystadenomas (SCAs). Robotic pancreatic enucleations were associated with less trauma, shorter operation time, less blood loss and faster wound recovery compared with open pancreatic enucleation. Pancreatic fistulas (PFs) were the main complication that occurred in the robotic group; infection also occurred in the open group. All patients recovered after effective drainage and the use of somatostatin. The mean follow-up time was 25 months. No recurrence was discovered, and one patient in the open group suffered endocrine insufficiency. CONCLUSION: Robotic pancreatic enucleation is a safe and effective surgical procedure for pancreatic benign and borderline tumours. It produces less trauma than open pancreatic enucleation and might extend the indications for enucleation. The PF rate after surgery is still high and a long-term follow-up needs to be performed.
