Abstract
INTRODUCTION Potential live liver donors with non-alcoholic steatohepatitis (NASH) are rejected upfront for donation in live donor liver transplantation (LDLT). Herein, we share our experience of the feasibility of live liver donation in donors with NASH after successful donor optimization. MATERIALS AND METHODS Prospectively collected data of 410 consecutive donor hepatectomies from June 2011 to January 2018 were analyzed. RESULTS During the study period, NASH was diagnosed histopathologically in 17 donors. Four donors were rejected in view of grade 2 fibrosis on histology. Out of remaining 13 donors, six became eligible for donation following lifestyle changes, dietary modifications, and target weight reduction of ≥5%. Reversal of NASH was confirmed on repeat liver biopsy in all the 6 donors. Five out of 6 underwent right lobe (without MHV) donor hepatectomies, while one had left lobe donation. These donors had significantly higher peak bilirubin levels in the immediate post-operative period as compared to other non-NASH donors (4.00 ± 0.32 vs. 2.57 ± 1.77 mg/dL, p = 0.043). In addition, post-hepatectomy normalization of hyperbilirubinemia, if any, was slower in donors with NASH (7 ± 1.3 vs. 5 ± 1.7 days, p = 0.016). However, none of these donors had post-hepatectomy liver failure. All these donors were discharged after an average hospital stay of 8 ± 1.7 days. Their respective recipients had uneventful post-operative courses without complications. Both the recipients and donors are having satisfactory liver functions after 46.7 ± 10.2 months of follow-up. CONCLUSION Scrupulous selection of live liver donors with NASH can open a door for expanding the organ pool in LDLT after a successful donor optimization program.

JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES 2021; 29:1124-1132. [PMID: 34623761 DOI: 10.1002/jhbp.1053] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/21/2021] [Revised: 08/08/2021] [Accepted: 09/13/2021] [Indexed: 11/08/2022]
Abstract
INTRODUCTION The duration of perioperative antibiotic prophylaxis following live liver donor hepatectomy (LDH) is not known. METHODS This is a double-blind equivalence trial. All consecutive LDH were randomized into: group A (three doses) and group B (nine doses) of perioperative antibiotics (piperacillin + tazobactam - 4.5 g intravenous) at fixed 8 hourly intervals. Primary end point was incidence of infective complications as per CDC (Centers for Disease Control and Prevention) criteria. Secondary end points were liver function tests, total leukocyte count, international normalized ratio, hospital stay, morbidity, and cost analysis. RESULTS One hundred and twenty-six LDHs were enrolled. A total of 19.8% (n = 25) experienced postoperative complications, 11 (17.7%) in group A and 14 (21.9%) in group B (P = .561). Infective complications were seen in 11 donors (8.1%), five in group A and six in group B (P = .79). A total of 8.1% of donors required continuation/up-gradation of antibiotics in group A and 9.4% in group B. Return to soft diet was delayed in group B (P = .039). Median hospital stay and cost were similar. CONCLUSION Three doses of perioperative antibiotic are equally effective in preventing infective complications.

Abstract
BACKGROUND MHV reconstruction is essential to avoid anterior sector congestion in adult live donor liver transplantation (LDLT) using a modified right lobe graft. AIMS The objective of this study is to evaluate the graft and patient outcomes with single orifice outflow reconstruction technique (SORT) (RHV + neo-MHV combined reconstruction on IVC) vs. dual outflow reconstruction technique (DORT) (RHV and neo-MHV separately reconstructed on IVC) in a modified right lobe LDLT. METHODS Prospectively collected data of consecutive patients undergoing LDLT from June 2011 to August 2018 were analyzed. The patients were divided into two groups: SORT (n = 207) and DORT (n = 108). The perioperative morbidity and mortality were compared between two groups. RESULTS The two groups were comparable in baseline preoperative characteristics. Intraoperatively, warm ischemia time (27 vs. 45 min, p < 0.001), anhepatic phase (132 vs. 159 min, p < 0.001), and operative time (680 vs. 840 min, p < 0.001) were significantly shorter in SORT group. SORT group also had significantly lower GRWR (0.92 vs. 1.06, p < 0.001) and higher portal flow (2.4 vs. 2.7 L/min, p = 0.02). Postoperatively, SORT group had lower peak AST (177 vs. 209 IU/L, p < 0.001), ALT (163 vs. 189 IU/L, p = 0.004), creatinine levels (0.98 vs. 1.10, p = 0.01), rate of severe sepsis (13.7% vs. 22.9%, p = 0.03), major morbidity (50.7% vs. 62.6%, p = 0.03), shorter ICU (9 vs. 14 days, p < 0.001), and hospital stay (21 vs. 26 days, p = 0.03). Overall survival rates were comparable. CONCLUSION A SORT leads to improved early graft function and perioperative morbidity in modified right lobe LDLT in spite of having lower GRWR and higher portal flow.

Abstract
Biliary complications (BCs) following living donor liver transplantation (LDLT) can lead to significant morbidity and occasional mortality. The present study describes our experience of the all-knots-outside technique (AKOT) of biliary reconstruction (BR) and its impact on BCs. A retrospective analysis was performed using prospectively collected data of 330 consecutive adult patients undergoing LDLT from July 2011 to February 2018 with a minimal follow-up of 24 months. Only 2.8% required hepaticojejunostomy and were excluded. In an initial 122 patients, BR was performed with the standard technique (ST), and AKOT was performed in the subsequent 208 patients. In the AKOT group, a single anastomosis was attempted even for multiple ducts whenever feasible. A major BC was defined as requiring endoscopic, percutaneous, or surgical interventions. In the AKOT group, significantly more patients received a left lobe graft (5.7% versus 18.3%; P = 0.001), had shorter warm ischemia time (44.6 versus 27 minutes; P < 0.001), and had a left hepatic artery (LHA) in the right lobe that was used for arterial reconstruction (48 [39.3%] versus 122 [58.6%]; P = 0.003). The incidence of BCs in the entire cohort was 47 (14.2%). For the ST versus AKOT groups, the overall BCs (27/122 [22.1%] versus 20/208 [9.6%]; P = 0.003) and major BCs (20.5% versus 6.7%; P < 0.001) decreased significantly. In the multivariate analysis, the number of bile ducts (hazard ratio [HR], 4.18; 95% confidence interval [CI], 1.62-10.78; P = 0.003), number of anastomoses (HR, 2.03; 95% CI, 1.03-4.02; P = 0.04), and technique of anastomosis (HR, 0.36; 95% CI, 0.19-0.68; P = 0.002) predicted BCs. In conclusion, in adult LDLT, with standardization of the donor and recipient surgery, preferential use of LHA for right lobe arterial reconstruction, reduction in the number of anastomoses, and AKOT for BR significantly decreased the incidence of BCs.

Preoperative Alanine Aminotransferase and Remnant Liver Volume Predict Liver Regeneration After Live Donor Hepatectomy. J Gastrointest Surg 2020; 24:1818-1826. [PMID: 31388890 DOI: 10.1007/s11605-019-04332-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2018] [Accepted: 07/16/2019] [Indexed: 01/31/2023]
Abstract
BACKGROUND Regeneration of the remnant liver in early postoperative period determines the outcome in live liver donors (LLDs). The aim of the current study is to evaluate the factors that influence liver regeneration following live donor hepatectomy. METHODS Total liver volume (TLV), estimated graft volume (EGV), and remnant liver volume (RLV) were calculated preoperatively in a prospective study of 154 LLDs. Absolute and percentage growth of remnant liver (regeneration index) in donor was estimated at 7th postoperative day (POD) by computed tomography (CT) volumetric analysis. RESULTS One hundred eighteen donors underwent right hepatectomy (RH), 29 underwent left hepatectomy (LH), 6 donors had left lateral sectionectomy (LLS), and one had right posterior sectionectomy. The median percentage growth of remnant liver at the end of the first week was 46.14% (51.74%, 35.32%, and 17.38% for RH, LH, and LLS, respectively). On univariate analysis, female donors (p = 0.051), RH graft (p = 0.001), no steatosis on ultrasonography (p = 0.042), lower TLV (p = 0.029), RLV (p = < 0.001), RLV-to-body weight ratio (RLVBWR) (p = < 0.001), preoperative alanine aminotransferase (ALT) level (p = 0.017), aspartate aminotransferase (AST) (p = 0.035) and higher POD 7 alkaline phosphatase (ALP) (p = 0.033), and POD 7 gamma-glutamyl transferase GGT (p = 0.006) were found to be predictors of greater liver regeneration. Among them, lower RLV (P = 0.008), RLVBWR (p = 0.011), and preoperative ALT level (p = 0.021) were most significant factors predictive of liver regeneration on logistic regression analysis with backward elimination. CONCLUSION The liver regenerates rapidly in LLDs following hepatectomy. Low RLV, RLVBWR, and preoperative ALT levels were predictors of liver regeneration in the first week following donor hepatectomy.

Symptomatic (Hypotensive) Bradycardia During Laparoscopic Living Donor Hepatectomy: Incidence and Risk Factors. Transplant Proc 2020; 52:1788-1790. [PMID: 32571703 DOI: 10.1016/j.transproceed.2020.01.161] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2019] [Accepted: 01/26/2020] [Indexed: 11/20/2022]
Abstract
BACKGROUND The use of a minimally invasive laparoscopic approach in living donor hepatectomy is increasing with the need for enhanced management of living donors. Hypotensive bradycardia often occurs during abdominal surgery and can be fatal without proper management. We conducted a retrospective study to investigate the incidence and risk factors of symptomatic (hypotensive) bradycardia in laparoscopic living donor hepatectomy. METHODS Hypotensive bradycardia is defined as the heart rate below 60 beats per minute with simultaneous mean arterial blood pressure (MAP) below 65 mm Hg. Clinical characteristics of liver donors were collected and analyzed from May 2018 to July 2019. RESULTS This study included 129 cases of living donor hepatectomy; 11 donors of open hepatectomy were excluded, and 118 donors undergoing laparoscopic hepatectomy were analyzed. Hypotensive bradycardia was shown in 27 donors. Hypertension or angiotensin receptor blocker medication were significantly related to hypotensive bradycardia. Hypotensive bradycardia occurred after incision in 22 donors, and the onset time from the incision was 7.5 minutes [first quartile (Q1) 5.75, third quartile (Q3) 11.5, range 0-25], the minimum heart rate was 48.5 beats per minute (Q1 41.5, Q3 53.25, range 25-57), and the minimum MAP was 55 mm Hg (Q1 45, Q3 57.5, range 35-63). It took 132 seconds (Q1 42, Q3 189, range 12-408) to recover MAP over 65 mm Hg. CONCLUSIONS Hypotensive bradycardia occurred in 22.9% of the laparoscopic living donor hepatectomy cases, and 80.6% of cases occurred after incision. Thorough preoperative evaluation and close monitoring is important even in a healthy donor.

Abstract
PURPOSE OF REVIEW As experience grows, living donor liver transplantation (LDLT) has become an effective treatment option to overcome the deceased donor organ shortage. RECENT FINDINGS Donor safety is the highest priority in LDLT. Strict donor selection according to structured protocols and center experience are the main factors that determine donor safety. However, with increased experience, many centers have explored increasing organ availability within living donation by means of ABO incompatible LDLT, dual graft LDLT, and anonymous living donation. Also, this growing experience in LDLT has allowed the transplant community to cautiously explore the role of liver transplantation for hepatocellular carcinoma outside of Milan criteria and patients with unresectable colorectal liver metastases. SUMMARY LDLT has become established as a viable strategy to ameliorate the organ shortage experienced by centers around the world. Improved understanding of this technique has allowed the improved utilization of live donor graft resources, without compromising donor safety. Moreover, LDLT may offer some advantages over deceased donor liver transplantation and a unique opportunity to assess the broader applicability of liver transplantation.
