ABSTRACT
Objective:To investigate the application value of three-dimensional (3D) printing technology assisted laparoscopic anatomic liver resection of segment 8 (Lap-S8).Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 8 liver cancer patients including 7 cases with hepatocellular carcinoma and 1 case with intrahepatic cholangio-carcinoma who underwent 3D printing technology assisted Lap-S8 in the Hunan Provincial People′s Hospital from January 2019 to December 2020 were collected. There were 7 males and 1 female, aged from 49.0 to 80.0 years, with a median age of 56.5 years. Of the 8 patients, 6 cases underwent laparoscopic anatomic liver resection of the entire segment 8, 1 case underwent laparoscopic anatomic liver resection of ventral subsegmental of the segment 8 and 1 case underwent laparoscopic anatomic liver resection of dorsal subsegmental of the segment 8. 3D printing technology was used to assist preoperative evaluation and intraoperative navigation for all 8 patients. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Follow-up was conducted using outpatient examination, internet or telephone interview to detect survival and tumor recurrence of patients after operation up to March 2021. Measurement data with normal distribution were represented as Mean±SD, and measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results:(1) Surgical situations: all the 8 patients underwent 3D printing technology assisted Lap-S8 successfully, without conversion to open surgery. The operation time, hepatic portal occlusion time and volume of intraoperative blood loss of the 8 patients were (216±41)minutes, (56±11)minutes and 75 mL(range, 50 to 300 mL), respectively. There was no intraoperative blood transfusion in 8 patients, and the surgical margin of the 8 patients was negative. (2) Postoperative situations: the duration of postoperative hospital stay of the 8 patients were (9±3)days. There was no complication such as postoperative hemorrhage, biliary fistula, liver abscess or abdominal infection occurred. (3) Follow-up: all the 8 patients were followed up for 3.0?24.0 months, with a median follow-up time of 12.5 months. During the follow-up, 1 of 8 patients with preoperative diagnosis of recurrent hepatocellular carcinoma developed tumor recurrence at 5 months after operation. The patient underwent laparoscopic surgery followed with the transcatheter arterial chemoembolization and target therapy, and survived with tumor. There was no tumor recurrence in the other 7 patients.Conclusion:3D printing technology assisted Lap-S8 is safe and feasible.

ABSTRACT
Nowadays,surgery is a comprehensive approach for the treatment of hepatic carcinoma as the first choice,but there are still many limitations in surgical therapy,such as the location,boundary and metastasis of hepatic carcinoma.Currently,the indocyanine green fluorescence imaging-guided hepatectomy is widely used at home and abroad as a new progress and hotspot in hepatobiliary surgery,which makes hepatobiliary surgery more convenient and makes up for some deficiencies in hepatectomy.Thus,we summarized the experience of indocyanine green fluorescence imaging-guided hepatectomy in the People's Hospital of Hunan Province and discussed its value of application.

ABSTRACT
Objective To investigate the application value of two-step separation approach in laparoscopic hemihepatectomy.Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 81 patients who underwent laparoscopic hemihepatectomy in the People's Hospital of Hunan Provincial between January 2015 and December 2017 were collected.Patients underwent laparoscopic hemihepatectomy using two-step separation approach after preoperative assessment.Hepatic pedicle,hepatic vein and branches were processed in the liver parenchyma,without intrathecal anatomy.Observation indicators:(1) preoperative assessment,intraand post-operative recovery;(2) follow-up and survival situations.Follow-up using outpatient examination and telephone interview was performed up to February 2018.Patients with hepatolithiasis received abdominal CT reexaminations at 5-7 days postoperatively for observing postoperative residual stones,and patients with malignant tumor were regularly followed up for 1-3 years.Measurement data with normal distribution were represented as (x)±s.Count data were described as frequency and percentage.Results (1) Preoperative assessment,intra-and post-operative recovery:81 patients underwent preoperative blood biochemistry,tumor biomarker and imaging examinations,and remaining functional liver volume and a liver model in 9 patients were respectively calculated and built using the 3D reconstruction software and 3D printing technology.Of 81 patients,68 underwent left hemihepatectomy and 13 underwent fight hemihepatectomy;77 underwent successful laparoscopic hemihepatectomy using two-step separation approach,4 were converted to open operation,with a rate of 4.9％ (4/81).Of 4 patients with conversion to open operation,1 had difficult tumor separation due to tumor invading port vein induced to close adhesion,1 had stone removal difficulties under laparoscopy due to hepatolithiasis,and 2 were converted to open operation due to severe liver cirrhosis induced to massive intraoperative bleeding.Of 81 patients,70 gained dividing line of hemiliver by intraoperatively hemihepatic blood flow occlusion,and then got effectively control of bleeding combined with Pringle blood flow occlusion,and 11 received Pringle blood flow occlusion in whole liver.Laparoscopic fluorescence imaging technology was intraoperatively used for 2 patients.Operation time,volume of intraoperative blood loss,rate of intraoperative blood transfusion and duration of hospital stay in 81 patients were respectively (206±42)minutes,(195±134)mL,11.1％(9/81) and (11.5+2.7)days.Eighty-one patients were complicated with bile leakage and were cured by conservative treatment,with a bile leakage incidence of 2.5％ (2/81),and without severe complications,such as postoperative bleeding,hepatic dysfunction and subphrenic abscess.There was no perioperative death and reoperation within 30 days postoperatively.(2) Follow-up and survival situations:55 patients with hepatolithiasis were followed up and underwent CT examinations of upper abdomen at 5-7 days postoperatively,including 52 with depletion of stones;3 with residual stones received removal of stones by choledochoscope at 3 months postoperatively,without residual stones.Seventeen patients with malignant tumor were followed up for 12-36 months,with a median time of 15 months,16 had tumor-free survival,and 1 was complicated with intrahepatic metastasis at 1 year after resection of hepatocellular carcinoma,and then underwent transcatheter arterial chemoembolization (TACE) and survived with tumor.Nine patients with benign liver diseases had good recovery during follow-up.Conclusion Two-step separation approach that is rationally used in laparoscopic hemihepatectomy is safe,effective and convenient.
ABSTRACT
Objective To study the experience in prevention and treatment of iatrogenic bile duct trauma(IBDT). Methods A retrospective study was made on the clinical data of 118 patients with iatrogenic bile duct trauma admitted to the Hunan Provincial People's Hospital from March 1990 to September 2000. Results 50.8% (60/118) of patients with IBDT resulted from the wrong identification of the anatomy of the Calot' Triangle during cholecystectomy. The clinical diagnosis of IBDT depended on the clinical findings, diagnostic abdominocentesis and image examination. The diagnostic rate of ultrasonography for IBDT was 93.2%(110/118). According to the injury site of bile duct, IBDT could be divided into 6 types, the most common type of IBDT was resection of partical hepatic duct and part common bile duct(type Ⅲ) which occurred in 83.9% (99/118) of the patients. The cure rate of IBCT was 100%(118/118) in this series due to the choice of operation according to the trauma type. Conclusions The key of prevention to IBDT lies in abiding by the princible of “identifying-cut-recognazing” during cholecystectomy. The choice for surgical operative procedure should agree with the trauma type.
