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.
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.
【Abstract】ObjectiveTo report the author’s experience with the first case of an adult-to-adult living donor liver transplantation (LDLT) for Budd-Chiari syndrome (BCS) using cryopreserved vena cava graft in postheptic vena cava reconstruction. MethodsA 35-year-old male patient with a diagnosis of BCS complicated with inferior vena cava (IVC) obstruction received medical treatment and radiologic intervention for nine months, no relief of the symptoms could be achieved. Finally, the patient underwent LDLT, which required posthepatic vena cava reconstructed using cryopreserved vena cava graft. ResultsThe patient has had an uneventful course since the LDLT. ConclusionWe believe that LDLT combined with posthepatic IVC reconstruction using cryopreserved vena cava graft is considered to be a sound modality for IVC obstructed BCS.
Objective To investigate the clinical choice on graft size and the type of donor’s hepatectomy in adult living related partial liver transplantation. Methods The literatures in recent years on the donor’s evaluation, the size of liver grafts, the types of donor hepatectomy and safety of donor in adult living related partial liver transplantation were reviewed.Results The size of liver graft is a crucial factor related to the safety of donor and the prognosis of the recipient. GW/ESLW≥30%, GW/BW≥0.8% may be the lowest limits. Left lobe contained middle hepatic vein, extended left lobe with leftside caudle lobe, right lobe or extended right lobe contained middle hepatic vein may be the practical choice.Conclusion It is important to make a reasonable choice of liver graft according to the estimation of GW/ESLW or GW/BW, and the anatomy of liver in adult living related partial liver transplantation.
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.
Objective To review the vascular anatomy of the donor and the reci pient for the l iving kidney transplantation. Methods The recent l iterature about the vessels of donor and reci pient in cl inical appl ications was extensively reviewed. Results The pertinent vascular anatomy of the donor and recipient was essential for the screening of the proper candidates, surgical planning and long-term outcome. Early branching and accessory renal artery of the donor were particularly important to deciding the side of nephrectomy, surgical technique and anastomosing pattern, and their injuries were the most frequent factor of the conversion from laparoscopic to open surgery. With increase of laparoscopic nephrectomy indonors, accurate venous anatomy was paid more and more attention to because venous bleeding could also lead to conversion to open nephrectomy. Multidetector CT (MDCT) could supplant the conventional excretory urography and renal catheter angiography and could accurately depict the donors’ vessels, vascular variations. In addition, MDCT can excellently evaluate the status of donor kidney, collecting system and other pertinent anatomy details. Conclusion Accurate master of related vascular anatomy can facil iate operation plan and success of operation and can contribute to the rapid development of living donor kidney transplantation. MDCT has become the choice of preoperative one-stop image assessment for living renal donors.
