Objective:To explore the clinical efficacy of the splenic vessel-oriented anatomical plane priority strategy in Da Vinci robotic Kimura distal pancreatectomy.Methods:A retrospective analysis was conducted on 26 patients who underwent robotic-assisted distal pancreatectomy at Zhejiang Provincial People’s Hospital from January 2019 to September 2024. The cohort included 7 male and 19 female patients, aged (49.3±16.7) years. Surgical outcomes, including operative time, intraoperative blood loss, postoperative complications, and hospital stay, were analyzed, and surgical techniques were summarized.Results:All 26 patients successfully completed the surgery. Pathological diagnoses included 5 cases of intraductal papillary mucinous neoplasm, 5 serous cystadenomas, 1 pancreatic neuroendocrine tumor, 6 solid pseudopapillary neoplasms, 4 mucinous cystic neoplasms, and 5 neuroendocrine tumors. The maximum tumor diameter was (2.3±1.1) cm, and the operative time was (183.2±77.4) min. The spleen preservation rate was 100% (26/26). Intraoperative blood loss was 50.0 (17.5, 125) ml, and postoperative hospital stay was (10.1±3.7) d. No Clavien-Dindo grade III or higher complications occurred. The post-operative pancreatic fistula (POPF) rate was 53.8% (14/26), including 38.5% (10/26) biochemical leak and 15.3% (4/26) grade B POPF, with no grade C POPF.Conclusion:The splenic vessel-oriented anatomical plane priority strategy in robotic-assisted spleen-preserving distal pancreatectomy (Kimura technique) is safe and feasible, significantly improving the spleen preservation rate.

BACKGROUND: Intensive phototherapy (IPT) and exchange transfusion (ET) are the main treatments for extreme hyperbilirubinemia. However, there is no reliable evidence on determining the thresholds for these treatments. This multicenter study compared the effectiveness and complications of IPT and ET in the treatment of extreme hyperbilirubinemia. METHODS: This retrospective cohort study was conducted in seven centers from January 2015 to January 2018. Patients with extreme hyperbilirubinemia that met the criteria of ET were included. Patients were divided into three subgroups (low-, medium-, and high- risk) according to gestational week and risk factors. Propensity score matching (PSM) was performed to balance the data before treatment. Study outcomes included the development of bilirubin encephalopathy, duration of hospitalization, expenses, and complications. Mortality, auditory complications, seizures, enamel dysplasia, ocular motility disorders, athetosis, motor, and language development were evaluated during follow-up at age of 3 years. RESULTS: A total of 1164 patients were included in this study. After PSM, 296 patients in the IPT only group and 296 patients in the IPT plus ET group were further divided into the low-, medium-, and high-risk subgroups with 188, 364, and 40 matched patients, respectively. No significant differences were found between the IPT only and IPT plus ET groups in terms of morbidity, complications, and sequelae. Hospitalization duration and expenses were lower in the low- and medium-risk subgroups in the IPT only group. CONCLUSIONS In this study, our results suggest that IPT is a safe and effective treatment for extreme hyperbilirubinemia. The indication of ET for patients with hyperbilirubinemia could be stricter. However, it is necessary to have a contingency plan for emergency ET as soon as IPT is commenced especially for infants with risk factors. If IPT can be guaranteed and proved to be therapeutic, ET should be avoided as much as possible.
