RESUMEN
BACKGROUND: Surgical therapy is the most optimal treatment for hepatocellular carcinoma (HCC) combined with bile duct tumor thrombus (BDTT) patients. However, whether to perform bile duct resection (BDR) is still controversial. The purpose of this multicenter research is to compare the effect of BDR on the prognosis of extrahepatic BDTT patients. METHODS: We collected the data of 111 HCC patients combined with extrahepatic BDTT who underwent radical hepatectomy from June 1, 2004 to December 31, 2021. Those patients had either received hepatectomy with extrahepatic bile duct resection (BDR group) or hepatectomy without bile duct resection (NBDR group). Inverse probability of treatment weighting (IPTW) was used to reduce the potential bias between two groups and balance the influence of confounding factors in baseline data. Then compare the prognosis between the two groups of patients. Cox regression model was used for univariate and multivariate analysis to further determine the independent risk factors that influence the prognosis of HCC-BDTT patients. RESULTS: There were 38 patients in the BDR group and 73 patients in the NBDR group. Before and after IPTW, there were no statistical significance in OS, RFS and intraoperative median blood loss between the two groups (all P > 0.05). Before IPTW, the median postoperative hospital stay in the NBDR group was shorter (P = 0.046) and the grade of postoperative complications was lower than BDR group (P = 0.014). After IPTW, there was no difference in postoperative hospital stay between the two groups (P > 0.05). The complication grade in the NBDR group was still lower than that in the BDR group (P = 0.046). The univariate analysis showed that TNM stage and portal vein tumor thrombus (PVTT) were significantly correlated with OS (both P < 0.05). Preoperative AFP level, TNM stage and prognostic nutritional index (PNI) were significantly correlated with postoperative RFS (all P < 0.05). Multivariate analysis showed that tumor TNM stage was an independent risk factor for the OS rate (P = 0.014). TNM stage, PNI and AFP were independent predictors of RFS after radical hepatectomy (all P < 0.05). CONCLUSIONS: For HCC-BDTT patients, hepatocellular carcinoma resection combined with choledochotomy to remove the tumor thrombus may benefit more.

AIM: Robotic-assisted pancreatectomy has been widely used. Organ-preserving pancreatectomy (OPP) and parenchymal-sparing pancreatectomy (PSP) has been gradually adopted for pancreatic benign or low-grade malignant tumors. This study aimed to evaluate the safety and efficacy of robotic-assisted OPP/PSP in our institute. METHODS: Patients undergoing robotic-assisted OPS/PSP at First Affiliated Hospital of Sun Yat-sen University between July 2015 and October 2021 were included in this study. The short-term and long-term outcomes of patients were retrospectively analyzed. RESULTS: Seventy-two patients were enrolled, including spleen-preserving distal pancreatectomy, central pancreatectomy, duodenum-preserving pancreatic head resection, and enucleation. Patients included were more likely to be young female (female: 46/72, median age: 47 years old). The median intraoperative blood loss and operation time was 50 ml and 255 min, respectively. Clinically relevant postoperative pancreatic fistula was 20.8% (grade B: 15/72, 20.8%; no grade C). The overall complication rate was 22.2% with the median postoperative length-of-stay of 8 days. At a median follow-up time of 28.5 months, the 5-year overall survival and recurrence-free survival rate were 100.0% and 100.0%, respectively. CONCLUSION: The short-term and long-term outcomes of patients receiving robotic-assisted OPP/PSP were acceptable. Robotic-assisted OPP/PSP was a feasible and safe technique for pancreatic benign or low-grade malignant lesions.

AIM: Splenic vessel-preserving spleen-preserving distal pancreatectomy (SVP-SPDP) has a lower risk of splenic infarction than the splenicvessel-sacrificing SPDP, but it is more technically demanding. Learning curve of robotic-assisted SVP-SPDP (RSVP-SPDP) remains unreported. This study sought to analyze the perioperative outcomes and learning curve of RSVP-SPDP by one single surgeon. METHODS: Seventy-four patients who were intended to receive RSVP-SPDP at the First Affiliated Hospital of Sun Yat-sen University between May 2015 and January 2023 were included. The learning curve were retrospectively analyzed by using cumulative sum (CUSUM) analyses. RESULTS: Sixty-two patients underwent RSVP-SPDP (spleen preservation rate: 83.8%). According to CUSUM curve, the operation time (median, 318 vs. 220 min; P < 0.001) and intraoperative blood loss (median, 50 vs. 50 mL; P = 0.012) was improved significantly after 16 cases. Blood transfusion rate (12.5% vs. 3.4%; P = 0.202), postoperative major morbidity rate (6.3% vs. 3.4%; P = 0.524), and postoperative length-of-stay (median, 10 vs. 8 days; P = 0.120) improved after 16 cases but did not reach statistical difference. None of the patients had splenic infarction or abscess postoperatively. CONCLUSION: RSVP-SPDP was a safe and feasible approach for selected patients after learning curve. The improvement of operation time and intraoperative blood loss was achieved after 16 cases.
