Living-Donor Liver Transplantation in Hepatitis C Virus Era: A Report of 500 Consecutive Cases in a Single Center.

BACKGROUND: Living donor liver transplantation (LDLT) is considered a safe alternative to deceased donor liver transplantation (DDLT). In Egypt, DDLT program is still awaited, making LDLT the only hope for patients with end-stage liver disease, mainly due to chronic hepatitis C virus (HCV) infection. The current study is conducted to evaluate our experience of LDLT and discuss the lessons learned from 500 consecutive cases in HCV area. METHODS: We reviewed the data of patients who underwent LDLT at Gastrointestinal Surgery Center, Mansoura University during the period between May 2004 and March 2017. RESULTS: During the study period, 500 cases underwent LDLT at our unit. The median age was 51 years, and most of our cases were males (446, 89.2%) and had HCV infection (453, 90.6%). The median MELD score was 15. Median ICU stay was 5 days, and hospital stay was 22 days. Postoperative morbidities occurred in 220 cases (44%). Early mortality occurred in 69 patients (13.8%), and late mortality occurred in 45 patients (9%). The 1-, 3-, 5-, and 7-year overall survival rates of all cases were 80.9%, 78.2%, 75.7%, and 75%, respectively. Preoperative creatinine, worm ischemia, blood transfusion, ICU stay, postoperative morbidities, and small for size syndrome were independent predictors for overall survival. CONCLUSIONS: In countries lacking DDLT, LDLT is the only effective alternative. LDLT requires a teamwork to achieve successful outcomes. LDLT should only be performed in centers with the adequate experience to avoid and decrease the hazards related to this procedure.

Predictive Factors of Liver Dysfunction After Right Hemihepatectomy for Adult Living Donor Liver Transplantation.

BACKGROUND: Living liver donors represent a special group of patients. They are healthy individuals who are exposed to a major surgery, in which the dominant liver proportion is extracted as a graft. Of all potential donor-related morbidities, posthepatectomy liver dysfunction (PHLD) is the most significant as it may be directly related to donor mortality. We aimed to review our data of adult living donor liver transplantation (LDLT) utilizing the right hemiliver grafts to determine the incidence and potential predictors for the development of PHLD, defined according to the International Study Group of Liver Surgery. METHODS: We reviewed the data of all adult living donors who underwent right hemihepatectomy during the period between May 2004 and 2016. RESULTS: During the study period, 434 cases underwent right hemihepatectomy for adult LDLT. We divided our cases into 2 groups according to the occurrence of PHLD. A significant lower residual liver volume and percentage were noted in PHLD group. Longer intensive care unit stay and hospital stay, and more postoperative morbidities, were observed in PHLD group. PHLD occurred in 50 cases (11.5%), and most of them were grade A (47 cases [10.8%]). Two cases (0.5%) had grade B requiring diuretic therapy, and 1 case (0.2%) had grade C requiring ultrasound guided tube drainage and surgical exploration finally. CONCLUSIONS: We should not underestimate the risks of liver donation surgery, especially when utilizing the right hemiliver graft. Donor safety should be ensured by accurate preoperative volumetric assessment of the remnant liver and remnant liver volume limitations must be strictly followed.

The effect of exposure to direct solar radiation on the semen characteristics of the male rabbit.

Three groups of cross-bred bucks (Baladi X standard breeds) were exposed to solar radiation for three hours per day during an 8-week experimental period in June and July and were compared with a control subgroup of the same age. Each subgroup (experimental and control) comprised 10 bucks, totalling 60 bucks. The effects were determined and assessed during the 28-week period following the experiment. The exposure to solar radiation at 5 or 12 weeks of age caused a delay in the onset of puberty. In all three groups, the concentration of sperms and the fructose content were decreased. There was a marked increase in the proportion of abnormal or dead sperms and in the methylene blue reduction time. The young animals were most affected by the exposure.
