ObjectiveTo analyze the clinical manifestations and pathological patterns of renal diseases requiring percutaneous renopuncture, evaluate the clinical significance of renal biopsy and the value of clinical pathway for renal biopsy. MethodsWe retrospectively summarized and analyzed the clinical and pathological data, and the clinical pathway implementation of 224 patients who underwent renal biopsy between October 2009 and September 2014. ResultsIn the 224 patients, there were 62 cases of IgA nephropathy (27.68%), 50 cases of minimal change nephropathy (22.32%), 28 cases of lupus nephritis (12.5%), 26 cases of membrane nephropathy (11.6%), 26 cases of mesangial proliferative glomerulonephritis (11.6%), 6 cases of purpura nephritis (2.68%), 4 cases of focal segmental glomerular sclerosis (1.79%), 4 cases of hepatitis B virus-associated membrane nephropathy (1.79%), 4 cases of nodular diabetic glomerulosclerosis (1.79%), 4 cases of acute tubulointerstitial nephropathy (1.79%), 2 cases of hypertensive renal damage (0.89%), 2 cases of membrano-proliferative glomerulonephritis (0.89%), 1 case of lipoprotein kidney disease (0.45%), and 1 case of fibrillary glomerulopathy (0.45%). A total of 220 specimens in the 224 cases were qualified, accounting for 98.21%. Diagnosis of 70 patients in the qualified 220 cases were re-corrected according to their renal pathology reports, accounting for 31.81%. In the 224 cases, there were 16 cases of gross hematuria (7.14%) and 24 of peri-renal hematoma (10.71%) after renal biopsy. Patients who met the requirement of clinical pathway were divided into clinical pathway group and control group randomly. Average hospitalization time of the clinical pathway group was (7.6±1.2) days, and the average cost was (5 860±237) yuan, both lower than the control group [(11.8±2.3) days, (7 658±360) yuan)]. The difference was statistically significant. ConclusionsIgA nephropathy is the most common pathological type of primary glomerular diseases, and minimal change nephropathy the second. Lupus nephritis, membranous nephropathy, mesangial proliferative glomerulonephritis are still the most common types of glomerular diseases. Lupus nephritis becomes the first secondary glomerular disease. Ultrasound guided percutaneous renal biopsy is safe and has high success rate and high clinical application value. The implementation of clinical pathway can shorten the average length of hospital stay and reduce the average hospital cost.
ObjectiveTo summarize the clinical progress on living related liver transplantation (LRLT). MethodsThe latest progress were reviewed based on recent documents and the experience on LRLT in our department. ResultsLRLT made much progress on evaluation of donor, harvesting the graft liver, donor health assessment and outcomes after living donor liver transplantation, and main factors affecting the survival of liver graft and so on. Conclusion Living related liver transplantation has many unsurpassable advantages, which suits the situation of China and has capacious clinical application.
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 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.
Objective To approach whether the postoperative recovery processes of the living donors and hepaticpatients after right hepatectomy is similar. Methods The clinical data of consecutive cases from 2009 to 2010 in our liver transplantation center was retrospectively analyzed, including 40 cases who donated the right lobe without the middlehepatic vein (living donor liver transpalntation-donor group, abbreviated as LDLT-D group) and 80 hepatic patients forright hepatectomy, in which 40 cases were hepatic patients without cirrhosis (liver disease-noncirrhosis group, abbreviatedas LD-NC group) and 40 cases were hepatic patients with cirrhosis (liver disease-with cirrhosis group, abbreviated asLD-WC group). Preoperative liver function and general clinical data, intraoperative blood loss and transfusion, postoper-ative liver function, and complications were statistically analyzed in this study. Results The preoperative parameters of three groups were comparable. LDLT-D group experienced more intraoperative bleeding than LD-NC group 〔(765±411) mL vs. (584±242) mL, P=0.008〕, and was similar to LD-WC group 〔(666±224) mL, P=0.136〕. However, the average amount of blood transfusion products was similar among the 3 groups (P=0.108). The levels of total bilirubin and INR of LDLT-D group were higher than LD-NC group and LD-WC group on the first and third day after operation (P<0.05). The levels of ALT and AST of LD-WC group were higher than LDLT-D group and LD-NC group (P<0.05). The overall postoperative surgical morbidity incidence of LDLT-D group, LD-NC group, and LD-WC group were 30.0%(12/40), 27.5% (11/40), and 37.5% (15/40) respectively, and were not statistically significant (P=0.606). However, the ClavienⅢcomplication rate of LD-WC group was higher than LDLT-D group and LD-NC group 〔27.5% (11/40) vs. 7.5%(3/40) and 10.0% (4/40), P=0.024〕. Conclusions Liver function of living donors is injured more seriously during the early postoperative period. The total complication rates after right hepatectomy are similar among the living liver donation and hepatic patients with or without cirrhosis. However, the serious complication rate of cirrhotic liver recipients is higher than living donors and patients without cirrhosis.
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.
