Purpose: This research aims to compare the efficacy of neoadjuvant hepatic arterial infusion chemotherapy (HAIC) combined with Lenvatinib (Len) to direct liver resection (LR) in patients with resectable or borderline resectable hepatocellular carcinoma (HCC). Methods: This retrospective study included 154 patients with hepatocellular carcinoma (HCC) treated at the a large-scale hepatocellular carcinoma Research Center between March 2019 and June 2023. Patients were assigned to one of two groups: 63 received neoadjuvant hepatic arterial infusion chemotherapy (HAIC) combined with Lenvatinib followed by liver resection (HAIC+Len→LR), while 91 received direct liver resection (LR). The primary outcomes assessed were median overall survival (mOS), median progression-free survival (mPFS), median duration of response (mDOR), and adverse events (AEs). Results: Patients in the HAIC+Len→LR group demonstrated significantly longer median overall survival (mOS) (40.1 months vs 35.9 months, P=0.001) and median progression-free survival (mPFS) (32.8 months vs 23.8 months, P=0.0023) compared to the LR group. Preoperative complete response (CR) to HAIC was associated with better median duration of response (mDOR) and mOS compared to partial response (PR) (not reached vs 28.9 months, P=0.006; 40.0 vs 29.1 months, P=0.037). Subgroup analysis revealed no significant difference in OS or PFS between the HAIC+Len→LR and LR groups in early Barcelona Clinic Liver Cancer (BCLC) stages. However, in late BCLC stages, the HAIC+Len→LR group exhibited significantly improved OS and PFS (HR 0.471, P=0.016; HR 0.551, P=0.022). Treatment-related grade ≥ 3 adverse events were comparable between the two groups. Conclusion: For patients with resectable or marginally resectable HCC in the intermediate to advanced stages of BCLC, surgery after neoadjuvant HAIC+Len may offer improved long-term prognosis.

Purpose: The purpose of This study is exploring the intraoperative and perioperative differences between patients undergoing conversion surgery and those undergoing direct surgery, so as to improve preoperative preparation. Methods: The retrospective study was approved by an ethics review committee. A total of 232 patients with hepatocellular carcinoma who underwent surgical resection at the First Affiliated Hospital of Chongqing Medical University from September 2022 to December 2023 were included, comprising 210 operating patients and 53 conversion patients. Propensity score matching was employed for comparison in order to minimize bias. Results: The conversion group had more intraoperative bleeding (each P=0.001), longer operation time (P=0.033; PSM p=0.025), and higher intraoperative blood transfusion rate (p=0.001; PSM p=0.044). The incidence of perioperative complications, including perioperative ascites formation (p=0.011; PSM p=0.005), moderate to severe anemia (p=0.001; PSM p=0.002), postoperative blood transfusion (p=0.004; PSM p=0.036), and postoperative ICU transfer (p=0.041; PSM p=0.025), was higher in the conversion group compared to the operation group. The postoperative hospital stay (p=0.001; PSM p=0.003) was prolonged in the conversion group. Conclusion: Post-conversion operations carry a higher risk of bleeding and are more likely to result in moderate to severe anemia and ascites formation in the perioperative period. However, the risk is reversible with adequate preoperative blood preparation and prompt postoperative symptomatic treatment. Conversion patients should be encouraged to undergo operating therapy when they can withstand surgical resection. [ABSTRACT FROM AUTHOR]

Background: The treatment of choledocholithiasis with nondilated common bile duct (CBD) is a challenge for surgeons who often choose endoscopic retrograde cholangiopancreatography with laparoscopic cholecystectomy (LC) staging surgery instead of simultaneous laparoscopic CBD exploration with LC because of the small CBD diameter. This study aims to introduce and assess the clinical applicability of a technique we developed to identify and extract CBD stones using laparoscopic ultrasound (LUS). Methods: We retrospectively reviewed surgical procedures and clinical data of 13 patients who underwent LC and CBD exploration using LUS between May 2022 and August 2023. The cystic duct was used for CBD stone removal. Results: Ten patients were successfully treated; 2 patients with residual stones were treated with ursodeoxycholic acid, whereas 1 patient required a microincision near the CBD and choledochoscopy because of stone incarceration in the duodenal papilla. The CBD diameter was 6 mm (5–9 mm). There were less than three CBD stones, with diameters of 2–6 mm; the median operative time was 105 minutes (range, 52–155 minutes). One patient developed postoperative cholangitis. The median postoperative hospital stay was 6 days (3–8 days). The stone clearance rate was 76.9%, and the CBD stone detection rate was 100%. No intraoperative complications, postoperative bile leakage, and mortality occurred. Conclusions: CBD exploration and transcystic stone extraction under LUS guidance are safe and effective approaches for patients with choledocholithiasis; strict control over surgical indications is necessary. This study could provide new strategies for effectively treating choledocholithiasis. [ABSTRACT FROM AUTHOR]
