Auxiliary partial orthotopic liver transplantation (APOLT) entails the removal of part of the native liver and replacement with the corresponding part of donor liver. APOLT is usually performed for acute liver failure and metabolic liver disease. However, many technical concerns limit its acceptance globally. In this study, we describe our experience of 6 APOLT performed for acute liver failure. Out of the 68 liver transplants performed in our center for acute liver failure, six were APOLT. APOLT was performed in the setting of hyperacute liver failure with no other organ failure. The recovery of the native liver was assessed using hepatobiliary scintigraphy every six months. Immunosuppressant withdrawal was attempted once 50% recovery of the native liver was attained in the scan. All donors were first-degree relatives. Etiology was hepatitis A in 4 patients, yellow phosphorous poisoning in 1, and cryptogenic fulminant hepatic failure in the remaining 1 patient. Five of them were blood group identical and one was ABO incompatible (AB to A). Post-operatively, three patients died, two due to massive cerebral edema, and one due to sepsis. All the survivors at a follow-up period of 2 years are off immunosuppressants and are doing well. Auxiliary liver transplant in acute liver failure has a poor success rate. However, the technique can be considered in a very selected group of patients with hepatitis A-related hyperacute liver failure. [ABSTRACT FROM AUTHOR]

Small bowel transplants are performed all over the world with acceptable success rates. Although there are isolated reports of small bowel transplants from India, a robust intestinal transplant programme similar to western countries is lacking. Our aim is to share our experience to build up on the evolving field of small bowel transplants in India. Deceased donor small bowel transplant was performed for three patients with intestinal failure, two for short gut syndrome following surgery and one for visceral myopathy. All were on preoperative total parenteral nutrition for varying periods of time (6 to 13 months). There were multiple episodes of line sepsis in all patients. Post-transplant, all received induction immunosuppression with anti-thymocyte globulin (first two patients) or alemtuzumab (3rd patient). All had systemic venous drainage and stoma. Protocol weekly intestinal biopsies were done in all patients. All died in hospital at 24, 12 and 28 days following surgery. Biopsy-proven rejection was observed in only patient who had received ABO-compatible non-identical graft (O to A). This patient subsequently developed vascular thrombosis necessitating explant of the graft. Sepsis due to multidrug resistant bacteria was the reason for mortality in the remaining two patients. Despite the absence of technical complications, successful small bowel transplant seems to be an elusive entity for the Indian transplant community. [ABSTRACT FROM AUTHOR]

Background: The role of N-acetylcysteine (NAC) in improving outcomes following live donor liver transplantation (LDLT) is not well established. We designed a randomized double-blind placebo-controlled trial to study the role of NAC infusion in recipients undergoing LDLT. Methods: We assigned 150 patients who underwent LDLT by computer-generated random sequence on 1:1 ratio to either NAC group or placebo group. Patients in the NAC group received NAC infusion which was started at beginning of graft implantation at an initial loading dose of 150 mg/kg/h over 1 h, followed by 12.5 mg/kg/h for 4 h and then at 6.25 mg/kg/h continued for 91 h. Placebo group received normal saline. The primary endpoint was composite occurrence of acute kidney injury (AKI) and early allograft dysfunction (EAD) in the recipient. Secondary endpoints included levels of bilirubin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine, INR, primary graft non-function, intraoperative bleeding, post-transplant hospital stay and in-hospital mortality. Results: The composite endpoint did not show any significant difference between the NAC and placebo group (21.3% vs 29.3%, p = 0.35). Peak AST (425.65 IU/L vs 702.24 IU/L, p = 0.02) and peak ALT (406.65 IU/L vs 677.99 IU/L, p = 0.01) levels were significantly lower in the study group. Time to normalization of transaminases was also significantly low in the study group. Conclusions: Perioperative NAC infusion following LDLT resulted in significantly lower postoperative AST and ALT levels. Rapid normalization of transaminases was also observed. This, however, did not translate to improvement in AKI or EAD. [ABSTRACT FROM AUTHOR]

Background: Although morbidity following living liver donation is well characterized, there is sparse data regarding health-related quality of life (HRQOL) of donors. Methods: HRQOL of 200 consecutive live liver donors from 2011-2014 performed at an Indian center were prospectively collected using the SF-36 version 2, 1 year after surgery. The effect of donor demographics, operative details, post-operative complications (Clavien-Dindo and 50-50 criteria), and recipient mortality on the quality-of-life (QOL) scoring was analyzed. Results: Among 200 donors (female/male=141:59), 77 (38.5%) had complications (14.5%, 16.5%, 4.5%, and 3.5%, Clavien-Dindo grades I-IV, respectively). The physical composite score (PCS) of donors 1 year after surgery was less than ideal (48.75±9.5) while the mental composite score (MCS) was good (53.37±6.16). Recipient death was the only factor that showed a statistically significant correlation with both PCS ( p<0.001) and MCS ( p=0.05). Age above 50 years ( p<0.001), increasing body mass index (BMI) ( p=0.026), and hospital stay more than 14 days ( p= 0.042) negatively affected the physical scores while emergency surgery ( p<0.001) resulted in lower mental scores. Gender, postoperative complications, type of graft, or fulfillment of 50-50 criteria did not influence HRQOL. On asking the hypothetical question whether the donors would be willing to donate again, 99% reiterated there will be no change in their decision. Conclusion: Recipient death, donation in emergency setting, age above 50, higher BMI, and prolonged hospital stay are factors that lead to impaired HRQOL following live liver donation. Despite this, 99% donors did not repent the decision to donate. [ABSTRACT FROM AUTHOR]

Antitubercular therapy (ATT)-induced hepatotoxicity is often over looked and active tuberculosis is considered a contraindication for liver transplantation, however it might be the only lifesaving option to certain patients of acute liver failure (ALF) due to ATT. We have assessed the outcome of live donor liver transplantation in ATT-induced ALF. A retrospective analysis of all the cases of ALF that underwent liver transplantation from 2006 to 2014 at the Amrita Institute of Medical Sciences was done. A total of seven (7.7%) patients with ATT-induced ALF who had underwent live donor liver transplantation were included in the study. Out of seven patients, three (42.8%) had established diagnosis of tuberculosis and the remaining (58.2%) patients were started on ATT empirically. The median duration of ATT intake was 2 months. All the patients underwent live donor liver transplant as they met King's College criteria, and their model for end-stage liver disease score was above 35 on admission, receiving graft from first degree relatives. Histopathology of explant liver showed pan acinar necrosis. Restarting of ATT after transplant was individualized. It was restarted only in two (28%) patients with prior sputum-positive pulmonary tuberculosis after a median time of 27 days after transplant. ATT was not restarted in rest of the (72%) patients. Postoperative mortality was seen in two (28%) patients due to conditions that masquerade the ATT-induced acute liver failure. The overall survival rate was 71.4% with a median follow up of 22 months. Live donor-related transplantation is feasible option in ATT-induced acute liver failure. Restarting of ATT post liver transplant is feasible and should be individualized along with frequent monitoring of immunosuppressant levels; however, if the primary diagnosis of tuberculosis was empirical, reintroduction of ATT can be omitted.

Zinc phosphide (ZnP) containing rodenticide poisoning is a recognized cause of acute liver failure (ALF) in India. When standard conservative measures fail, the sole option is liver transplantation. Records of 41 patients admitted to a single centre with ZnP-induced ALF were reviewed to identify prognostic indicators for requirement of liver transplantation. Patients were analyzed in two groups: group I ( n = 22) consisted of patients who either underwent a liver transplant ( n = 14) or died without a transplant ( n = 8); group II ( n = 19) comprised those who survived without liver transplantation. International normalized ratio (INR) in group I was 9 compared to 3 in group II ( p < 0.001). Encephalopathy occurred only in group I. Model for End-Stage Liver Disease (MELD) score in group I was 41 compared to 24 in group II ( p < 0.001). MELD score of 36 (sensitivity of 86.7 %, specificity of 90 %) or a combination of INR of 6 and encephalopathy (sensitivity of 100 %, specificity of 83 %) were the best indicators of mortality. Such patients should undergo urgent liver transplantation. [ABSTRACT FROM AUTHOR]

Introduction: Long-term anticoagulation is associated with hemorrhage at various sites. Gastrointestinal intramural bleeds and hematomas (IMH) often mimic mesenteric ischemia (MI) due to similar clinical settings and imaging features, making early differentiation difficult. Aim: To compare the demography, clinical features and imaging characteristics of patients presenting with IMH with those of MI, so as to help in evolving clinical and imaging guidelines to differentiate both early in the course of the disease. Methods: All radiologically (contrast-enhanced computed tomogram [CT]) diagnosed cases of gastrointestinal IMH from the hospital database during the period between 2006 and 2012 were retrospectively analyzed. This data was compared with the clinical and imaging features of a group of surgically confirmed MI during the same period. Patients not on anticoagulation therapy at the time of presentation and those with incomplete clinical or radiological data were excluded from the study. Results: There were 16 patients in IMH group and 54 patients in MI group. Clinical features like overt rectal bleeding or melena, and prolonged prothrombin time-international normalized ratio (PT-INR) more than three, and CT features like proximal location in the bowel, increased bowel wall thickness, hyperdensity on plain scan (>40 Hounsfield units (HU)), and short segment bowel involvement were significantly associated with IMH. Visualization of embolus and absent mesenteric vasculature to a segment of intestine in CT was significantly associated with MI. Conclusion: Attention to clinical features and early CT scan can aid in early differentiation of IMH from MI, facilitating appropriate intervention early in the course of disease.
