Abstract
The obesity epidemic has profoundly impacted the epidemiology and trends of liver disease. In the current era, non-alcoholic fatty liver disease (NAFLD) progressing to non-alcoholic steatohepatitis (NASH) has emerged as the second leading indication for liver transplant (LT) and has been associated with the rising rates of hepatocellular carcinoma (HCC) with and without underlying cirrhosis. Obesity has been associated with poor post-transplant outcomes including lower patient and graft survival; higher risk of post-operative metabolic complications; poor wound healing; and higher infection rates. Bariatric surgery is currently the most effective management of morbid obesity and has been offered to patients both in the pre and post LT setting. The techniques attempted in LT recipients most commonly include sleeve gastrectomy (SG), gastric bypass surgery with few cases of gastric banding and biliopancreatic diversion. However, there is lack of evidence-based data on the optimal management for patients with obesity and who are liver transplant candidates and/or recipients. In the following discussion, we present the highlights from a review of the literature.

Liver Decompensation after Bariatric Surgery in the Absence of Cirrhosis. Obes Surg 2022; 32:1227-1235. [PMID: 35138516 DOI: 10.1007/s11695-022-05930-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2021] [Revised: 01/22/2022] [Accepted: 01/23/2022] [Indexed: 02/07/2023]
Abstract
PURPOSE Metabolic dysfunction-associated fatty liver disease-related cirrhosis is possible at the time of bariatric surgery, complicated by further liver decompensation. Hepatic decompensation can also occur in the absence of cirrhosis but the presentation is less clear. METHODS We analyze the clinical characteristics, histological findings, and management of patients without cirrhosis who developed hepatic decompensation after bariatric surgery in our single tertiary-care hospital. RESULTS From 2014 to 2019, 6 patients underwent a transvenous liver biopsy for liver decompensation after bariatric surgery. Mean age at diagnosis was 44 years. The time between bariatric surgery and the onset of symptoms varied widely (min. 8 months, max. 17 years). Mean % of weight loss was high at 43%. The clinical presentation was as follows: fatigue and jaundice (5/6), leg edema (3/6), and ascites (1/6). Blood test showed increased transaminases (mean ALT 53 UI/L, mean AST 130 UI/L), bilirubin (mean 6 mg/dL), and INR (mean 1.5) with a low albumin level (mean 27 mg/dL). The hepatic venous pressure gradient was high (mean 10 mmHg). Histology revealed steatosis, hepatocyte ballooning but also portal inflammation with polymorphonuclear cells, and bile duct alterations. Mean fibrosis score was 2. The clinical course was favorable with nutritional support with a mean follow-up of 36 months. CONCLUSION Liver decompensation in the absence of cirrhosis can occur after bariatric surgery with a highly variable delay. A special histological signature is present with the coexistence of steatosis, bile duct alterations, and portal inflammation. Substantial clinical improvement with appropriate nutritional support seems to be effective.

Abstract
INTRODUCTION Nowadays morbid obesity has become a worldwide health issue and the use of bariatric surgery undoubtedly results not only in weight reduction but also in the improvement of comorbidities. Although bariatric surgery is the optimal choice for metabolic syndrome resolution and hepatic function improvement, there is evidence that in rare cases it may lead to aggressive steatohepatitis, acute liver failure, fibrosis, and deterioration of the overall prognosis, without having fully understood the underlying pathophysiological mechanisms. CASE REPORT In this case report we present a 45-year-old female patient with morbid obesity, body mass index 80, who underwent long-limb Roux en Y gastric bypass (LL-RYGB) and was admitted to the emergency department with jaundice and impaired liver function laboratory tests on postoperative day 90. The examinations revealed elevated bilirubin and transaminases, with prolonged prothrombin time and low albumin levels. A liver biopsy was performed and showed active steatohepatitis. The hepatic values were gradually further impaired and the decision for surgery, in order to reverse the hepatic dysfunction, was taken. A gastrostomy in the bypassed stomach was performed and the activation of the closed biliopancreatic loop led to clinical improvement and amelioration of the prognosis. CONCLUSIONS Patients at high risk for hepatic failure after bariatric surgery should be better evaluated preoperatively and a tailor-made approach should be applied in order to avoid such a disastrous complication.

Abstract
Introduction Obesity and the associated metabolic syndrome are global health problems. Significant weight loss after bariatric surgery can cause a substantial difference in those comorbidities in obese patients. In this case, we described a rare complication of a patient who developed acute liver failure after an uneventful one anastomosis gastric bypass treated conservatively and revision of the one anastomosis gastric bypass to normal anatomy. Case presentation We present a 52-year-old female known to have hypothyroidism and morbid obesity with a BMI of 45. For that, she underwent uneventful one anastomosis gastric bypass. Later, she developed liver failure and hepatic encephalopathy, which was managed conservatively and revision surgery to normal anatomy. Discussion Bariatric surgery plays an integral role in treating obese patients for its associated impacts, like facilitating weight loss and related metabolic syndrome improvement. The effects of bariatric surgery on liver functioning are controversial. Some malabsorptive procedures are linked to postoperative hepatic complications. However, it is uncommon in a recent new technique in bariatric surgery. Liver transplant and revision of the bariatric surgery have been described as management. However, optimal nutrition support without a liver transplant along with revision surgery is possible in experienced hands. Conclusion Early detection of liver impairment and early intervention by a revision to normal anatomy by an experienced surgeon is considered the safest and most effective procedure for such patients. However, late detection where liver failure occurs, liver transplantation is the only effective treatment for preventing fatal outcomes. Revision of one anastomosis gastric bypass as a treatment for liver failure Optimizing the nutritional status is essential in revision surgeries. Monitoring of liver status post-bariatric surgery is important. An experienced bariatric surgeon should do the revision surgeries.

Abstract
BACKGROUND Protein malnutrition and bacterial overgrowth occurring after bariatric surgery (BS) might cause severe liver failure (LF) needing liver transplantation (LT). OBJECTIVES To evaluate indications and outcomes of LT for BS-related LF. SETTING University hospital in France. METHODS The EMBASE, MEDLINE, and COCHRANE central databases were systematically searched according to the PRISMA criteria from inception up through December 2017 for articles describing LT for LF after BS. RESULTS Fourteen studies reporting 36 patients listed for LT, of which 32 underwent the procedure, were retained. The types of previously performed BS included jejunoileal bypass (n = 16), bilio-pancreatic diversion according to Scopinaro (n = 14) or with duodenal switch (n = 3), bilio-intestinal bypass (n = 1), long-limb Roux-en-Y gastric bypass (n = 1), and single anastomosis omega gastric bypass (n = 1). Liver failure developed a median of 20 months after BS (mean ± SD: 105 ± 121 mo; range, 5-300 mo). This interval of time was significantly shorter after biliopancreatic diversion than jejunoileal bypass (mean ± SD: 22 ± 21 mo versus 269 ± 27 mo; P = .0001). Four patients (11.1%) died while on the waiting list for LT, and 4 more (12.5%) died after LT. Morbidity and liver retransplantation were reported in 8 (25%) and 2 (6.2%) patients, respectively. Twenty-one patients (65.6%) had their BS procedure reversed (1 patient before, 15 patients during, and 5 patients after LT, respectively). Biopsy-proven steatosis recurrence after LT was reported in 6 patients (18.7%), 4 of whom did not have BS reversal. CONCLUSIONS Severe LF occurring after BS, although rare, might require LT. When indicated, LT is effective at restoring liver function, even when BS reversal is performed synchronously.

Liver Function in Patients With Nonalcoholic Fatty Liver Disease Randomized to Roux-en-Y Gastric Bypass Versus Sleeve Gastrectomy: A Secondary Analysis of a Randomized Clinical Trial. Ann Surg 2017; 266:738-745.

Abstract
OBJECTIVES The aim of the study was to compare the influence of sleeve gastrectomy (SG) versus Roux-en-Y gastric bypass (RYGB) on liver function in bariatric patients with non-alcoholic fatty liver disease (NAFLD) in a randomized clinical trial (NCT01806506). BACKGROUND Rapid weight loss and malabsorption after bariatric surgery in patients with NAFLD or steatohepatitis (NASH) may impair liver function. METHODS Sixty-six morbidly obese patients randomized to SG or RYGB were included in a secondary outcome analysis. Intraoperative liver biopsies were categorized with NAFLD Activity Score (NAS) and liver function tests were done before surgery and after 1, 6 and 12 months. RESULTS NASH was present in 54.5% RYGB and 51.5% SG patients (P > 0.05). At 12 months excess weight loss was 68.7 ± 19.7% after SG and 62.8 ± 18.5% after RYGB (P > 0.05). At 1 month international normalized ratio (INR) increased after RYGB (0.98 ± 0.05 vs 1.14 ± 0.11; P < 0.05) and SG (0.99 ± 0.06 vs 1.04 ± 0.06; P < 0.05), RYGB induced significantly greater increase in INR in the whole group and NASH patients than SG. After RYGB albumin decreased at 1 month (41.2 ± 2.7 vs 39.0 ± 3.2 g/L; P < 0.05). At 12 months, INR and albumin returned to baseline. At 12 months in NASH group, SG induced significant improvement in aspartate aminotransferase (32.4 ± 17.4 vs 21.5 ± 6.9U/L), alanine aminotransferase (39.9 ± 28.6U/L vs 23.8 ± 14.1U/L), gamma-glutamyl transpeptidase (34.3 ± 16.6 vs 24.5 ± 16.8U/L), and lactate dehydrogenase (510.8 ± 33 vs 292.4 ± 29). Variables predictive of INR change after 1 month included operation type, NAS ≥ 5, bilirubin, body mass index, hemoglobin A1C, and dyslipidemia. CONCLUSIONS Patients with NASH undergoing RYGB are more susceptible to early transient deterioration of liver function than after SG.
