ABSTRACT
Hepatolithiasis is a common biliary disease in China. Surgical treatment principles of hepatolithiasis include "removing lesions, cleaning stones, correcting strictures, recovering the drainage and preventing the recurrence". Laparoscopic techniques have been increasingly applied in surgical treatment of hepatolithiasis recently. Right posterior bile duct is a predilection site of hepatolithiasis. Due to its unique anatomy, right posterior lobectomy, right posterior bile duct lithotomy and plasty remain challenging under laparoscopy. Based on relevant literatures and clinical experiences, the authors explore the strategy of laparoscopic treatment right posterior bile duct hepatolithiasis, aiming to provide reference for surgical colleagues.
ABSTRACT
Objective:To explore the current status of surgery for portal hypertension to grasp current status and future development of surgery in China.Methods:This study is jointly sponsored by China Hepatobiliary & Pancreatic Specialist Alliance & Portal Hypertension Alliance in China (CHESS).Comprehensive surveying is conducted for basic domestic situations of surgery for portal hypertension, including case load, surgical approaches, management of postoperative complications, primary effects, existing confusion and obstacles, liver transplantation(LT), laparoscopic procedures and transjugular intrahepatic portosystemic shunt(TIPS), etc.Results:A total of 8 512 cases of portal hypertension surgery are performed at 378 hospitals nationwide in 2021.Splenectomy plus devascularization predominated(53.0%)and laparoscopy accounted for 76.1%.Primary goal is preventing rebleeding(67.0%) and 72.8% of hospitals used preventive anticoagulants after conventional surgery.And 80.7% of teams believe that the formation of postoperative portal vein thrombosis is a surgical dilemma and 65.3% of hospitals practiced both laparoscopy and TIPS.The major reasons for patients with portal hypertension not receiving LT are due to a lack of qualifications for LT(69.3%)and economic factors(69.0%).Conclusions:Surgery is an integral part of management of portal hypertension in China.However, it is imperative to further standardize the grasp of surgical indications, the handling of surgical operation and the management of postoperative complications.Moreover, prospective, multi-center randomized controlled clinical studies should be performed.
ABSTRACT
Objective:To study the safety and efficacy of laparoscopic cholecystectomy (LC) in treatment of T2a and lower stages of gallbladder carcinoma.Methods:A retrospective study was performed on patients who were diagnosed with gallbladder cancer and underwent surgical treatment from January 2016 to January 2021 at Hunan Provincial People's Hospital. These patients were divided into the simple treatment group and the radical treatment group based on the surgical methods used. The simple treatment group consisted of 64 patients who underwent LC for accidental gallbladder cancers. The radical treatment group consisted of 30 patients who underwent laparoscopic radical cholecystectomy (LRC). The baseline characteristic of the two groups of patients were matched in a 1∶1 ratio using propensity score matching. After matching, there were 26 patients in each of the 2 groups. There were 7 males and 19 females in the simple group, with mean ± s. d. age of (60.6±9.6) years. There were 8 males and 18 females, with mean ± s. d. age (60.9±9.1) years in the radical treatment group. Blood loss, operation time, postoperative hospital stay, biliary leakage, acute pulmonary embolism, and incisional infection were compared between the two groups.Results:In the simple group, the operative time was (78.7±62.9) min, intraoperative blood loss was (10.7±11.6) ml and postoperative hospital stay was (4.4±2.6) d. These results were significantly better than those in the radical group with operative time (298.7±101.3) min, intraoperative blood loss (161.9±96.7) ml and postoperative hospital stay (9.9±4.0) d (all P<0.05). There were no significant difference in the postoperative complications and disease free survival rates between the two groups (both P>0.05). Conclusion:LC was safe and effective for treatment of T2a and lower stages of gallbladder cancer, and it could achieve a similar disease-free survival rate as LRC.
ABSTRACT
Objective:To analyze the causes of postoperative stricture of biliary-enteric anastomotic for congenital choledochal cysts.Methods:These 28 patients underwent salvage operation on an average 15 years (0.2-25 years) after initial surgeries at the Department of Hepatobiliary Surgery, Hunan Provincial People's Hospital from Jan 2014 to Jun 2018.Results:In 26 patients the biliary-enteric anastomotic stenosis was benign, and in 2 the stricture was caused by cancerration. In 26 cases the Roux-en-Y hepaticojejunostomy was redone,among them 8 cases underwent concurrent hepatectomy for a better exposure of the intrahepatic bile duct. In 2 cases the anastomotic stenosis was found to be caused by canceration with extensive intraabdominal metastasis ,an external drainage was adopted. There were no inhospital deaths, and no serious complications. The postoperative follow-up time was 6-67 months. Two cancerated patients died within half a year, and the remaining patients had no long-term complications.Conclusions:Biliary-enteric anastomotic stenosis is one of the serious complications in postoperative patients for congenital choledochal cysts. Hence a wide, tension free biliary-enteric anastomosis performed by a experienced hand is necessary.
ABSTRACT
Objective:To evaluate partial ventral hepatectomy in the treatment of patients with complicated iatrogenic high bile duct injury.Methods:The clinical data of 8 cases of complicated iatrogenic high bile duct injury treated with the assistance of hepatic ventral segmentectomy from Mar 2013 to May 2020 at Hunan Provincial People's Hospital was retrospectively analyzed.Results:Among the 8 patients, 5 patients underwent partial Ⅳb lobectomy, and 3 patients received partial Ⅳb and Ⅴ segmentectomy of the liver. All the operation was successful without death in hospital. One case developed subphrenic infection and seroperitoneum, which was healed by anti-infection treatment and abdominocentesis. The postoperative follow-up time was 5-90 months, and all of patients are doing well. There was no stenosis in intrahepatic bile duct by postoperative cholangiography or MRI.Conclusions:Quadrate lobe hepatectomy provides a wide view for the treatment of complicated iatrogenic high bile duct injury by fully opening the first porta hepatis and exposing the primary and secondary bile duct branch helping establish a wide patent tension free bile duct-jejunostomy.
ABSTRACT
Objective:To study and analyse the results of postoperative hemorrhage after laparoscopic pancreaticoduodenectomy (LPD).Methods:The clinical data of patients who underwent LPD from May 2011 to December 2019 at Hunan Provincial People's Hospital were retrospectively analyzed. The clinical characteristics of patients, onset time of postoperative hemorrhage, location of postoperative hemorrhage, postoperative biliary fistula, pancreatic fistula, infection and other short-term complications, reoperation and mortality rates were analyzed.Results:Of 356 patients who underwent LPD in this study, there were 200 males and 156 females, aged (58.0±10.5) years. The postoperative complication rate was 33.1% (118/356), the reoperation rate was 6.5% (23/356), and the mortality rate was 2.5% (9/356). The most common complications were postoperative hemorrhage [15.2% (54/356)], pancreatic fistula [14.6%(52/356)] and abdominal infection [13.8%(49/356)]. The onset time of postoperative hemorrhage was usually in the 1st - 14th day, and the highest rate of postoperative hemorrhage was 3.9% (14/356) on the first day after surgery. The postoperative hemorrhage rate then showed a downward trend, but increased again on the 7th day. The extraluminal hemorrhage locations were relatively widely distributed, and the incidence of gastrointestinal anastomotic hemorrhage in patients with intraluminal hemorrhage was the highest [67.9%(19/28)]. Of the 9 patients who died, 7 were related to postoperative bleeding.Conclusions:LPD resulted in a high incidence of complications. Postoperative hemorrhage was a complication that had the greatest impact on short-term recovery of patients. It was also an important cause of reoperation and death. In addition to postoperative bleeding caused by pancreatic fistula, gastrointestinal anastomotic bleeding was also clinically important.
ABSTRACT
Acute abdomen is often a general term for abdominal diseases with acute abdominal pain as the main manifestation. Common clinical acute abdomen includes acute appendicitis, acute cholecystitis, acute cholangitis, acute pancreatitis, gastrointestinal perforation, intestinal obstruction and other diseases, its characteristics are great changes, rapid progress, high misdiagnosis rate, high postoperative complication rate and high mortality rate, accurate diagnosis and early treatment can obtain a good prognosis. With our in-depth understanding of the occurrence and development of acute abdomen diseases and the development of evidence-based medicine, minimally invasive technology plays a pivotal role in the diagnosis and treatment of common acute abdomen. Laparoscopy on diagnosis can clarify disease diagnosis to a large extent. For those who cannot undergo surgery, decompression and drainage under endoscopy provides a diversified plan for treatment decisions. In addition, minimally invasive techniques are also used in etiological treatment and complications. Disease, prevention of recurrence in all aspects, Minimally invasive technology is beneficial to the etiological treatment of biliary pancreatitis, appendicitis and cholangitis, and endoscopic technology is more consistent with the minimally invasive concept in the treatment of complications.
ABSTRACT
Laparoscopic anatomical hepatectomy of segment 7 is recognized as one of the most difficult hepatectomies. Because of its location and anatomic characteristics, the resection of hepatic segment 7 has the difficulties of poor surgical view, instrumental accessibility, hepatic pedicle anatomy, confirmation of dividing line and secure hemostasis. When performing laparoscopic anatomical hepatectomy of segment 7, the authors routinely put patient at left semi-decubitus position, set all trocars at the right upper quadrant of the abdomen, and select proper approach for hepatic pedicle anatomy according to the results of individualized preoperative three-dimensional reconstruction. The authors use to transect the liver parenchyma at the plane between hepatic segment 6 and segment 7, with the direction perpendicular to the right hepatic vein, and then finish parenchymal dissection using right hepatic vein as the intrahepatic landmark. According to the authors experiences, choosing appropriate tactics can effectively reduce the difficulty of laparoscopic anatomical hepatectomy of segment 7, improve the safety and controllability of operation, and ensure the oncological radical effects.
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
Laparoscopic anatomical resection (LAR) is a highly-demanding and high risky procedure.Traditional single-surgeon technique appears to be frustrating when dealing with intro-operative emergency and ensuring the safety of complicated LAR.The authors' department has applied two-surgeon technique when performing LAR since 2014.In complicated cases of LAR,two skillful surgeons cooperate to perform surgeries.The two surgeons stand at each side of the patient and switch their duties as the surgeon or the assistant during the operation.Experience of the authors' department shows that compared with single-surgeon technique,two-surgeon technique can help better deal with intro-operative accidental events such as hemorrhage and guarantee the safety of LAR,as well as enhance the efficiency and quality of procedures.Two-surgeon technique benefits team building and training young laparoscopic liver surgeons,and help them pass the learning curve more safely and quickly.
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
Laproscopic anatomical hepatectomy (LAH) is a highly-demanding procedure.Single-surgeon technique,which is widely adopted in open hepatectomy,can no longer meet the demands of LAH very well.Our department is one of the first hepatobiliary surgery centers which routinely applied Two-Surgeon Technique when performing LAH.Two-Surgeon Technique means having two skillful and experienced surgeons cooperate LAH,the two surgeons exchange their duty of Surgeon or Assistant as needed during the operation.Two-surgeon Technique can better guarantee the safety of LAH,as well as enhance the efficiency and quality of procedures.
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.

Objective To investigate the clinical efficacy of three-dimensional (3D) and two-dimensional (2D) laparoscopic surgeries in the treatment of Todani type Ⅰ choledochal cyst.Methods The retrospective cohort study was conducted.The clinical data of 59 patients with Todani type Ⅰ choledochal cyst who were admitted to the People's Hospital of Hunan Province between January 2013 and January 2016 were collected.Thirty patients undergoing 2D laparoscopic surgery between January 2013 and June 2014 were allocated into the 2D group and 29 patients undergoing 3D laparoscopic surgery between July 2014 and January 2016 were allocated into the 3D group.There were the same Trocar placement and surgical procedure in the 2 groups,and surgical procedure completely followed the treatment principle of Todani type Ⅰ choledochal cyst.Observation indicators included (Ⅰ) surgical situations:conversion to open surgery,operation time,volume of intraoperative blood loss,(2) postoperative situations:postoperative complications,(3) follow-up.Patients were followed up by outpatient examination or telephone interview to detect postoperative recovery up to April 30,2016.Measurement data with skewed distribution were presented as M (range) and analyzed using the Mann-Whitney U test.Count data were compared by Fisher exact probability.Results (1) Surgical situations:patients in the 2 groups underwent laparoscopic choledochal cystectomy + Roux-en-Y hepaticojejunostomy.Two patients in the 2D group received conversion to open surgery and patients in the 3D group received the successful surgery without conversion to open surgery.Rate of conversion to open surgery in the 2D and 3D groups were 6.7% (2/30) and 0,respectively,with no statistically significant difference (P > 0.05).Operation time in the 2D and 3D groups were 285 minutes (range,240-390 minutes) and 190 minutes (range,140-215 minutes),with a statistically significant difference (U =40.0,P < 0.05).Volume of intraoperative blood loss in the 2D and 3D groups were 50 mL (range,10-300mL) and 45 mL (range,20-250 mL),with no statistically significant difference (U =1 018.5,P > 0.05).(2)Postoperative situations:patients in the 2 groups had good recovery,without occurrence of severe complications in Clavien-Dindo≥ Ⅲ stage.Four and 1 patients in the 2D and 3D groups were complicated with bile leakage (in Ⅱ stage of Clavien-Dindo) and 1 and 1 were complicated with upper gastrointestinal hemorrhage (in]][stage of Clavien-Dindo),respectively,with no statistically significant difference (P > 0.05).Overall incidence of complications in the 2D and 3D groups were 16.7% (5/30) and 10.3% (3/29),with no statistically significant difference (P > 0.05).All the patients were cured by conservative treatment.(3) Follow-up:59 patients were followed up for 5-36 months,with good recovery and without occurrence of reflux cholangitis,hepatic and intestinal anastomosis stenosis and reoperation.Conclusions 3D and 2D laparoscopic surgeries are safe and effective for Todani type Ⅰ choledochal cyst.Compared with 2D laparoscopic surgery,3D laparoscopic surgery can reduce the operation time and not increase the complications,and it should be discreetly promoted based on the experiences of surgeons.
