Objective To investigate quality of life of pediatric living donor liver transplantation recipient (PLDLTR) and analyze it’s influencing factors. Methods The convenient sampling method was adopted. Fifty-three PLDLTRs from May 2012 to January 2017 in the West China Hospital of Sichuan University were selected. At the same time, 56 children who participated in the physical examination and had no abnormality results were selected as reference (control group), their age and gender matched with the PLDLTRs. A general data inventory and a self-assessment scale for children’s quality of life (Pediatric Quality of Life Inventory 4 Generic Core Scales, PedsQL4.0) were used to evaluate the quality of life of the 53 PLDLTRs. Results A total of 53 questionnaires were distributed to all the 2 groups, all of them were effectively recovered. The points of quality of life of the physiological function, emotional function, social function, and school performance for the PLDLTRs were significantly higher than those of the control group (P<0.050), which for the PLDLTRs with male and more than 3 years after the operation were significantly higher than those of the PLDLTRs with female and within 1 year after the operation (P<0.050). For the PLDLTRs with age >4 years old, the points of the emotional function, social function, and school performance were significantly higher than those of the PLDLTRs with age ≤4 years old. For the PLDLTRs without postoperative complications, the points of quality of life of the physiological function, emotional function, and school performance were significantly higher than those of the PLDLTRs with Ⅱ grade of postoperative complications (P<0.050). Conclusions Life quality of PLDLTR is poorer than that of normal children. Postoperative time, postoperative complications, age, and gender are certainly associated with quality of life for PLDLTR.
ObjectiveTo evaluate donor safety in living donor liver transplantation. MethodsThe clinical data of 356 donors underwent living liver donation in our center from January 2001 to September 2015 were retrospectively analyzed. These patients were divided into pre-2008 group(before January 2008) and post-2008 group(after January 2008). The donor safety was evaluated with regard to three aspects, i.e. complications, liver function, and quality of life. Results①There was no donor death in our center.②The overall complications rate was 23.3%(83/356). The proportion of ClavienⅠ, Ⅱ, Ⅲ, andⅣcomplications was 50.6%(42/83), 26.5%(22/83), 21.7%(18/83), and 1.2%(1/83), respectively. In all the donors, the incidence of ClavienⅠ, Ⅱ, Ⅲ, andⅣcomplications was 11.8%(42/356), 6.2%(22/356), 5.1%(18/356), and 0.3%(1/356), respectively. The overall complications rate in the post-2008 group was significantly lower than that in the pre-2008 group〔18.1%(41/227) versus 32.6%(42/129), P < 0.01〕. The most common complication was the biliary complication with an incidence of 8.4%(30/356).③The postoperative liver dysfunction was transient and generally retur-ned to normal level within a week.④The donor's quality of life was generally satisfied as assessed by the SF-36 tool, and 94.8%(239/252) of them would donate again if necessary. ConclusionEver improving surgical and anesthetic techniques, together with strict donor selection and specialized perioperative management, could guarantee a low donor morbidity and a satisfactory long-term prognosis.
【Abstract】Objective To study the anatomy of the hepatic arteries and imitate the way to deal with the hepatic arteries in the living liver transplantation of the left lateral lobe.Methods Thirty normal adult livers were anatomyzed and 30 casting models of livers were observed. The lengths, diameters and distributaries of the hepatic arteries were described.Results The blood supply of the left lateral region came from proper hepatic artery, left hepatic artery and middle hepatic artery. The aberrant arteries included left inferior phrenic artery, left gastric artery and right gastric artery. They branched to supply the upper segment and the inferior segment.Conclusion There are five types of hepatic arteries to supply the left liver lobe. The anatomy of hepatic arteries should be studied and a reasonable approach to gain a liver graft should be designed before transplantation. The hepatic arteries should be dealt with so as to anastomose with recipient hepatic arteries.
Objective To report our experience in living donor liver harvesting of right lobe grafts. MethodsThe data of 76 living donors of right lobe grafts hepatectomy between August 2007 and December 2008 were studied. Before operation, the graft size, remnant liver volume rate, fatty liver, middle hepatic vein type, and the level of portal hypertension of recipient were comprehensive assessed to determine whether harvested middle hepatic vein. The graft was harvested depending on the port vein and hepatic artery ischemia-line. B-ultrasound was used to definite the structure and branch of middle hepatic vein, and intraoperative cholangiography was performed to definite the structure and variation of bile duct. Donor operative time, intraoperative blood loss, postoperative hospital stay, levels of bilirubin, international normalized ratio （INR）, and ALT, and complications after operation were recorded. Results All the operations were successful. The operative time was (8.3±1.3) h, the blood loss was (325±127) ml without blood transfusion in operation. The ALT, INR, and bilirubin recovered on the 12th day. The most common complication in early post-operation was wound infection in 5 cases, 4 cases had cholestasis, 4 cases occurred cross-section bile leakage, and 11 cases occurred varying degrees of delayed gastric emptying in 4～7 d after operation, who were all alleviated by corresponding treatments. The hospital stay was 9～21 d (median: 14 d) after operation. Conclusion Preoperative evaluation of the hepatic anatomy and precise surgical procedure are crucial, which will help the development of graft harvesting and rehabilitation of donor.
ObjectiveTo review the causes, prevention methods, and therapies of the small-for-size syndrome (SFSS) in living donor liver transplantation (LDLT). MethodsThe literatures about SFSS in recent years were reviewed and summarized. ResultsThe donor’s age, graft steatosis level, MELD score of the recipient, portal hypertension, low outflow, and graft size were risk factors of SFSS. Ideal donor, splenectomy, ligating splenic artery, keeping a satisfactory intraoperative outflow, early diagnosis and active therapy could obviously decrease the incidence of SFSS. ConclusionThe risk factors of SFSS can be predicted before operation, and the positive actions can be used to prevent or cure the SFSS.
Objective To discuss venous drainage types of median hepatic lobe and their guiding significances on the selection of grafts. Methods Between April 2005 and March 2009, 109 potential living donors underwent 3-dimensional reconstruction of computed tomography (CT) and the volume of graft was determined in the center of organ transplantation of Ruijin Hospital. The venous drainage types of median hepatic lobe of each donor were analyzed by the computer-based liver operation-planning system in detail to assign middle hepatic vein (MHV) types according to Marcos classification and venous types of Ⅳb segment according to Nakamura classification. Results The branching pattern of MHV was divided into 3 types: Type Ⅰ and Ⅱwere relatively more accounting for 44.0% （48/109）, 37.6% （41/109）, and type Ⅲ was fewest 〔18.3% （20/109）〕. There were no significant differences in volume of whole liver, volume of left liver or left liver/total liver volume ratio among various types of MHV of the donor (Pgt;0.05). Ⅳb vein was also divided into 3 types: The most common was type Ⅰ, accounting for 72.4% (79/109); Type Ⅱ 〔12.8% （14/109）〕, type Ⅲ 〔14.7% （16/109）〕 were relatively fewer. At last, 37 donors provided right liver, for Marcos Ⅰ, Ⅱ, and Ⅲ type of donors, donors remained with MHV was 12/17, 8/11, and 5/9; for Nakamura Ⅰ, Ⅱ, and Ⅲ type of donors, those number were 16/26, 4/6, and 5/5. Conclusion In adult-to-adult living donor liver transplantation, there may be great significances in accordance with Marcos and Nakamura typing results to harvest right lobe liver graft with or without MHV.
ObjectiveTo investigate the radiological appearances of postoperative complications after living donor liver transplantation for patients with hepatocellular carcinoma under multi-detector row spiral computed tomography (MDCT) and magnetic resonance imaging (MRI) examination. MethodsThirty-nine imaging data in 20 patients with hepatocellular carcinoma after living donor liver transplantation from January 2008 to June 2010 in the West China Hospital were included and analyzed by two radiologists respectively. The relations between the types of complications and radiological appearances were especially recorded. ResultsAll the cases experienced complications to different extent. Common surgical complications occured in 20 cases, including pertitoneal fluid collection (14 cases), pneumoperitoneum (2 cases), swelling of peritoneum, omentum, and mesentery (1 case), abdominal wall swelling (2 cases), pleural effusion (9 cases), and pericardial fluid collection (2 cases). Hepatic vascular complications involved hepatic artery in 3 cases, portal vein in 5 cases. Biliary complications presented in 7 cases, including anastomotic stenosis of biliary duct (6 cases) and bile leak (1 case). Graft parenchymal complications included intrahepatic lymph retention (11 cases), infarction (3 cases), and infection (2 cases). Intrahepatic recurrence in 5 cases, intraperitoneal metastasis in 3 csses and pulmonary metastasis in 2 cases. ConclusionMDCT and MRI have important diagnostic values for postoperative complications after living donor liver transplantation for patients with hepatocellular carcinoma.
ObjectiveTo more comprehensive understanding the survival situation of donors after liver transplantation, which can be applied to clinical diagnosis and treatment. MethodsThe related literatures in recent years of living donor liver transplantation (LDLT) postoperative complications, quality of life, and liver regeneration were reviewed, and the donors postoperative survival situation were investigated. ResultsLDLT has become an option, It is safe and feasible for healthy adults to donate partial liver for LDLT. ConclusionsDonor postoperative survival situation is very important, and it affect the development of LDLT.To improve donors postoperative survival situation, we still need more efforts.
Minimally invasive surgery played a crucial role in modern medicine. With advantages such as less trauma, precise operation, minimal bleeding, and rapid postoperative recovery, minimally invasive procedures had been increasingly applied in the field of liver transplantation in recent years. This included techniques such as small incision living donor hepatectomy through an upper abdominal midline incision, laparoscopic-assisted living donor hepatectomy, pure laparoscopic living donor hepatectomy, and robotic living donor hepatectomy. Since Professor Cherqui from France firstly reported the total laparoscopic left lateral sectionectomy in living donors in 2002, the application of minimally invasive technology in living donor liver transplantation had become increasingly widespread. Based on this, so as to guide the more standardized, effective, and safe implementation of minimally invasive liver donor hepatectomy across the country, in August 2023, the Branch of Organ Transplant of Chinese Medical Association and the Branch of Organ Transplant Physicians of Chinese Medical Doctor Association organized national liver transplantation experts to jointly formulate the “Chinese guidelines for minimally invasive surgical techniques in living donor liver transplantation (2024 edition)”. This is to provide scientific guidance and reference for surgeons performing minimally invasive surgery on living liver donors in China.
