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
Objective@#To investigate the safety and feasibility of longitudinal transpancreatic U-sutures invaginated pancreatojejunostomy (Chen′s pancreaticojejunostomy technique) in laparoscopic pancreaticoduodenectomy (LPD) .@*Methods@#Clinical data of 116 consecutive patients who underwent LPD using Chen′s pancreaticojejunostomy technique in Hunan Provincial People′s Hospital from May 2017 to December 2018 were retrospectively analyzed. Among these patients, 66 were males and 50 were females. The median age was 58 years old (32-84 yeas old). All 116 patients underwent pure laparoscopic whipple procedure with Child reconstruction method, using Chen′s pancreaticojejunostomy technique. The intraoperative and postoperative data of patients were analyzed.@*Results@#All 116 patients underwent LPD successfully. The mean operative time was (260.3±33.5) minutes (200-620 minutes). The mean time of pancreaticojejunostomy was (18.2±7.6) minutes (14-35 minutes) . The mean time of hepaticojejunostomy was (14.6±6.3) minutes (10-25 minutes). The mean time of gastrojejunostomy was (12.0±5.5) minutes (8-20 minutes). The mean estimated blood loss was (106.0±87.6) ml (20-800 ml). Postoperative complications were: 11.2% (13/116) of cases had postoperative pancreatic fistula (POPF) , including 10.3% (12/116) of biochemical fistula and 0.9% (1/116) of grade B POPF, no grade C POPF occurred; 10.3% (12/116) had gastrojejunal anastomotic bleeding; 3.4% (4/116) had hepaticojejunal anastomotic fistula; 3.4% (4/116) had delayed gastric emptying; 4.3% (5/116) had localized abdominal infection; 12.1% (14/116) had pulmonary infection; postoperative mortality were 0(0/116) and 1.7% (2/116) within 30 days and 90 days, respectively. One patient died of massive abdominal bleeding secondary to Gastroduodenal artery pseudoaneurysm rupture, the other patient died of extensive tumor recurrence and metastasis after surgery.@*Conclusions@#Chen′s pancreaticojejunostomy technique is safe and feasible for LPD.It is an option especially for surgeons who have not completed the learning curve of LPD.

Objective@#To assess the safety and feasibility of the application of the laparoscopic modality in the perioperative treatment of central liver tumors.@*Methods@#Collecting all the clinical information of a total of 40 patients with central liver tumors who received laparoscopic resection treatment carried out at Department of Hepatological Surgery of People′s Hospital of Hunan Provincial from January 2016 to December 2018 to take a retrospective review. There were 19 males and 21 females.The age was (59.5±14.5) years (range: 15 to 71 years) . There were 26 cases of primary hepatic carcinoma (24 cases of hepatocellular carcinoma, 2 cases of cholangiocellular carcinoma) , 8 cases of hepatic cavernous hemangioma, 1 case of metastatic hepatic carcinoma, 5 cases of hepatocellular adenoma. The maximum diameter of tumors were (6.2±2.9) cm (range: 2 to 13 cm) . The patient′s information about hepatectomy methods, blocking mode and time of blood flow, operation time, intraoperative blood loss, intraoperative blood transfusion rate, post-operative hospitalization time, perioperative reoperation and postoperative complications were collected.@*Results@#A total of 40 patients all were treated with laparoscopic surgery.

ABSTRACT
Objective To investigate the influencing factors and prognosis of early and late recurrence after radical resection of primary hepatocellular carcinoma(HCC).Methods The clinical data of 117 patients who received radical resection of HCC at the Tongji Hospital of Huazhong University of Science and Technology from January 2003 to December 2006 were retrospectively analyzed.Tumor recurrence occurred within 2 years after operation was defined as early recurrence,and tumor recurrence occurred latter than 2 years after operation was defined as late recurrence.Relationship between postoperative tumor recurrence and level of alpha-fetoprotein (AFP),AFP/V,tumor diameter,tumor number,blood vessel invasion,tumor differentiation,hepatic cirrhosis,hepatic function,hepatitis B surface antigen,procedure of hepatic resection and blood transfusion was analyzed.The overall survival and disease-free survival rates were determined by Kaplan-Meier method,and the survival rate was analyzed by Log-rank test.Results Eighty-five(72.6％)patients were found with tumor recurrence,including 59(50.4％)with early tumor recurrence and 26(22.2％)with late tumor recurrence.Levels of AFP,AFP/V,tumor diameter,tumor number,blood vessel invasion,tumor differentiation and blood transfusion were the influencing factors of early recurrence(x2 = 12.78,13.40,5.79,9.98,10.26,9.48,8.32,P ＜ 0.05).Level of AFP and hepatic cirrhosis were the influencing factors of late recurrence(x2 =4.46,7.75,P ＜ 0.05).AFP/V,tumor number and blood vessel invasion were the independent risk factors of early recurrence(RR = 0.170,0.172,0.064,P ＜ 0.05).Hepatic cirrhosis was the independent risk factor of late recurrence(RR = 2.809, P ＜ 0.05).The 1-,3-,5-year overall survival rates and tumor-free survival rates were 82.6％,60.8％,54.9％ and 65.0％,38.5％,23.1％.There were significant differences in overall survival and disease-free survival rates among patients with AFP ＜20 μg/L,AFP/V ＜ 14 μg/(L · cm3)or AFP/V ≥ 14 μg/(L · cm3)(P ＜ 0.05).The 1-,3-,5-year overall survival rates of patients with early tumor recurrence were 64.9％,23.0％ and 20.5％,respectively,and the 1-,3-,5-year overall survival rates of patients with late tumor recurrence were 100.0％,88.5％ and 72.5％,respectively.A significant difference in the 1-,3-,5-year overall survival rates between patients with early or late tumor recurrence was observed(x2 = 26.918,P ＜0.05).Conclusions AFP/V,tumor number,blood vessel invasion were independent risk factors of early tumor recurrence,and hepatic cirrhosis was the independent risk factor of late tumor recurrence.There is a significant difference in the survival rate between patients with early or late tumor recurrence.
