Abstract
PURPOSE Hypoalbuminemia following One-Anastomosis Gastric Bypass (OAGB) surgery remains a major concern among bariatric surgeons. This study aims to assess the outcome of partial reversal to normal anatomy with gastro-gastrostomy alone in patients with refractory hypoalbuminemia following OAGB surgery. METHODS A retrospective study was performed on patients who underwent partial reversal surgery with gastro-gastrostomy alone due to refractory hypoalbuminemia post-OAGB surgery, using data from the Iran National Obesity Surgery Database, from 2013 to 2022. RESULTS Of 4640 individuals undergoing OAGB, 11 underwent gastro-gastrostomy due to refractory hypoalbuminemia. The median time from OAGB to partial reversal was 16.6 months and the BPL length ranged from 155 to 200 cm. The follow-up period ranged from 1 to 7 years. The mean BMI was 27.3 (7.5) kg/m² before partial reversal. The mean BMI post-reversal was 30.9 (4.2) kg/m² after 1 year and 33.3 (3.8) kg/m² after 2 years. Serum albumin levels significantly increased from 3.0 (0.4) g/dL to 4.0 (0.5) g/dL following gastro-gastrostomy (p-value < 0.001). Serum liver enzymes (SGOT, SGPT, ALP) significantly decreased post-gastro-gastrostomy (p-value < 0.05). Nine individuals (81.8%) achieved resolution of hypoalbuminemia after gastro-gastrostomy with maintenance of ≥ 20% TWL and ≥ 50% EWL. No cases of anastomotic stricture, leak, bleeding, or major complications were reported after gastro-gastrostomy. CONCLUSION Gastro-gastrostomy appears to be a safe and efficacious technique for addressing refractory hypoalbuminemia following OAGB. The procedure preserves the weight loss achieved following OAGB without significant complications. However, further studies are required to validate these findings.

Bidares M, Melali H, Aziz M, Salehi M. Laparoscopic Roux-en-Y Versus Mini-Gastric Bypass on Liver Function at 6 Months in Morbid Obesity Patients: A Cross-Sectional Study. HEPATITIS MONTHLY 2024; 24. [DOI: 10.5812/hepatmon-141884] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Revised: 03/04/2024] [Accepted: 05/09/2024] [Indexed: 01/03/2025]
Abstract
Background: Various weight loss surgeries exist, with no absolute superiority; each has pros and cons. Due to rising bariatric surgeries globally, it's vital to investigate comparisons between two-mini gastric bypass and Roux-en-Y gastric bypass (RYGB), especially regarding their impact on liver function. Objectives: The purpose of this study was to "draw comparisons between the effects of mini gastric bypass and laparoscopic Roux-en-Y gastric bypass on liver function at 6 months among patients with morbid obesity." Methods: This cross-sectional study included 90 bariatric surgery candidates (Body Mass Index (BMI) 35 - 50) from 2018 - 2021. Forty-five had laparoscopic mini gastric bypass surgery, while 45 had Roux-en-Y gastric bypass. Demographic, anthropometric, lab, and sonographic tests were conducted at baseline, 3-, and 6-months post-surgery. Data was analyzed using SPSS. Results: In a study of 90 patients (75.6% female, mean age 38.6 ± 10.4 years), both surgeries (Mini gastric bypass (MGB) and RYGB) effectively reduced body weight, BMI, and waist circumference at 3- and 6-months post-surgery. However, MGB showed significantly higher BMI and weight loss compared to RYGB (P = 0.003). In 90 patients, both surgeries reduced weight and BMI. However, MGB showed better BMI/weight loss. LFTs (ALT, AST, ALP) remained stable after MGB but worsened at 3 months after RYGB before recovering by 6 months. Mini gastric bypass also showed better GGT improvement. Both procedures improved fatty liver grading, FBS, and HbA1C levels equally. No significant differences were observed in blood pressure, platelet count, hemoglobin, or MCV. Ferritin levels increased in both groups but were higher in RYGB. CRP was higher in RYGB at 3 months. Conclusions: Roux-en-Y gastric bypass temporarily exacerbated liver enzymes and inflammation, but MGB resulted with more weight reduction. In comparison to RYGB, MGB improved LFTs more consistently.

The Association of Demographic Characteristics with the Rate of Weight Loss and Changes in Nutritional Factors (Albumin, Vitamin D3, Ferritin) One Year after One Anastomosis Gastric Bypass. Adv Biomed Res 2023; 12:192. [PMID: 37694235 PMCID: PMC10492623 DOI: 10.4103/abr.abr_442_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2022] [Revised: 03/09/2023] [Accepted: 03/15/2023] [Indexed: 09/12/2023] Open
Abstract
Background The effect of bariatric surgery on weight loss (WL) of patients with severe obesity is an established finding. However, some studies have shown that other factors such as demographic characteristics can also be involved in the extent of success and relapse of obesity. Thus, this study was performed to determine the association of demographic characteristics with the rate of weight loss and changes in nutritional factors one year after one anastomosis gastric bypass (OAGB). Materials and Methods In this cross-sectional study, 121 patients undergoing OAGB were investigated. Patients' body mass index (BMI), nutritional factors (including levels of albumin, vitamin D3, and serum ferritin), and demographic characteristics were measured one year after the surgery. Results The BMI one year after surgery was significantly lower than before surgery (47.12 ± 5.08 kg/m2 vs. 29.42 ± 3.86 kg/m2; P value <0.001). WL was 37.37 ± 6.70%. In addition, the serum level of vitamin D3 one year after surgery with the mean of 44.54 ± 17.25 was significantly higher than its level before surgery with the mean of 38.13 ± 14.42 (P value <0.001). WL in less than 50 years old and married patients was significantly higher than WL in over 50 years old and single patients (P value <0.05). Moreover, the decrease in serum ferritin level with the mean of 1.90 ± 0.56 ng/ml in women was significantly higher than its decrease with the mean of 3.02 ± 0.94 ng/ml in men (P value = 0.003). Conclusion Some demographic characteristics such as age, gender, and marital status seem to affect the rate of weight loss or ferritin level one year after OAGB.

Abstract
BACKGROUND In comparison to conservative therapy, bariatric surgery has shown many reasonable results. The current study investigates whether Omega-loop-gastric-bypass (OAGB) or Roux-en-Y gastric-bypass (RYGB) improves weight loss, comorbidities, and perioperative complications. METHODS The study included 28,683 patients after RYGB and OAGB. Outcome criteria were perioperative morbidity, perioperative complications, and remission of comorbidities after one year of follow-up. RESULTS Of them 14,253 patients had completed a one-year follow-up (13,483 patients by RYGB and 770 by OAGB). BMI reduction was a significant difference in favor of OAGB (17.5±5.6 kg/m2 for OAGB vs. 15.2±5.0 for RYGB; P<0.001). The %EWL was not significantly different between the two groups (P=0.073). There was also no significant difference in perioperative complications between the two groups (overall P>5%). Significant differences in favor of OAGB were observed in remission of insulin-dependent diabetes mellitus (IDDM) (P<0.001), and sleep apnea (P=0.002). Remission of reflux was more observed in RYGB than OAGB (P<0.001). Operating time was significantly higher in RYGB than OAGB (P<0.001). CONCLUSIONS Compared with RYGB, OAGB showed significant advantages in many respects. In particular, remission of comorbidities was significantly better after OAGB than in patients after RYGB during the one-year follow-up period. Nevertheless, many other factors such as medical history, long-term expected goals of bariatric surgery, and preexisting comorbidities should be taken into account when determining indications between the two procedures. Further studies with longer follow-up periods should be conducted to determine the efficacy of the two methods more accurately.

Abstract
Aim: To assess the effect of bariatric surgery on the lean mass of women after one year of the procedure, comparing its outcomes upon the classification from both the Foundation of the National Institutes of Health (FNIH) and the European Working Group on Sarcopenia in the Elderly People (EWGSOP). Material and methods: Twenty-eight obese women aged 40.5 ± 9.8 yrs who underwent Roux-en-Y gastric bypass (RYGB) were included. 27 of them were reassessed after 6 months of surgery, and 16 completed the one-year follow-up. Pre-sarcopenia condition was assessed through a handgrip strength test and body composition by dual-energy X-ray absorptiometry (DXA). Total body mass, body mass index, and lean mass (LM) were collected prior to, 6 and 12 months after RYGB surgery. Results: All subjects reassessed after 12 months were diagnosed with pre-sarcopenia according to the FNIH classification criteria, while according to the EWGSOP2 Consensus they presented normal values. LM represented 14% of the influence on handgrip strength (p = .049) after 6 months of surgery; however, its influence on strength after 12 months increased to 30% (p = .028). Conclusion: The FNIH classification is the most effective criteria since it uses LM content as the first test, considering that strength capacity needs more time to be affected by the surgical procedure. On the other hand, the EWGSOP2 classification should not be applied to determine the loss of LM in younger populations regardless of what may have caused such changes.

A Specifically Tailored Multistrain Probiotic and Micronutrient Mixture Affects Nonalcoholic Fatty Liver Disease-Related Markers in Patients with Obesity after Mini Gastric Bypass Surgery. J Nutr 2022; 152:408-418. [PMID: 34919684 DOI: 10.1093/jn/nxab392] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2021] [Revised: 10/31/2021] [Accepted: 11/17/2021] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is frequent among patients undergoing bariatric surgery. Beyond weight reduction, dietary supplements like micronutrients or probiotics that modify insulin resistance and lipotoxicity can be used to prevent or delay the progression of liver disease. OBJECTIVES We evaluated the effect of a dietary approach with a specifically tailored multistrain probiotic and micronutrient mixture compared with a basic care micronutrient supplement on serum alanine aminotransferase (ALAT) in obese patients after mini gastric bypass (MGB) surgery. METHODS This randomized, double-blind, controlled trial included 60 obese patients (age: 40 ± 10 y; BMI: 44 ± 3 kg/m²). Patients received a combination of specifically tailored multistrain probiotic powder and a specific micronutrient mixture (Pro+SM) or a control treatment consisting of a placebo and a basic care micronutrient mixture (Con+BM), with some micronutrients in lower doses than SM, for 12 wk after hospital discharge. Primary (serum ALAT) and secondary outcomes [serum aspartate aminotransferase (ASAT), fatty liver index, NAFLD fibrosis score, glucose metabolism, blood pressure (BP), heart rate] were assessed at week 0 and week 12. Data were analyzed using unpaired Student's t-tests or Mann-Whitney U tests to compare the changes due to each treatment to one another. RESULTS A total of 48 patients were included in the analyses. Changes in serum ALAT concentrations did not differ between groups. Compared with Con+BM, Pro+SM improved serum ASAT (difference: -8.0 U/L, 95% CI: -17.0, -4.0; P = 0.043), NAFLD fibrosis score (difference: -0.39; 95% CI: -0.78, 0; P = 0.048), serum triglycerides (difference: -22.8 mg/dL; 95% CI: -45.6, -0.1; P = 0.049) and the visceral adiposity index (difference: -0.70; 95% CI: -1.31, -0.08; P = 0.027). CONCLUSION Supplementation with a specifically tailored probiotic and micronutrient mixture improved NAFLD-related markers more than a basic micronutrient mixture in obese patients following MGB surgery. The trial was registered under clinicaltrials.gov as NCT03585413.

Abstract
The International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) issued a position statement on the role of one anastomosis gastric bypass (OAGB) in the field of bariatric/metabolic surgery in 2018 De Luca et al. (Obes Surg. 28(5):1188-206, 2018). This position statement was issued by the IFSO OAGB task force and approved by the IFSO Scientific Committee and IFSO Executive Board. In 2018, the OAGB task force recognized the necessity to update the position statement in the following 2 years since additional high-quality data could emerge. The updated IFSO position statement on OAGB was issued also in response to inquiries to the IFSO by society members, universities, hospitals, physicians, insurances, patients, policy makers, and media. The IFSO position statement on OAGB has been reviewed within 2 years according to the availability of additional scientific evidence. The recommendation of the statement is derived from peer-reviewed scientific literature and available knowledge. The IFSO update position statement on OAGB will again be reviewed in 2 years provided additional high-quality studies emerge.

Abstract
The effects of bariatric procedures on nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) remain unclear. A systematic review and meta-analysis was performed to compare the impact of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) on NAFLD/NASH. Patients submitted to RYGB presented significant reduction of steatohepatitis (RD: 0.53; 95% CI 0.33 to 0.74) and fibrosis (RD: 0.26; 95% CI 0.14 to 0.37). SG caused a significant reduction of steatohepatitis (RD: 0.42; 95% CI 0.27 to 0.57), but not of fibrosis (RD: 0.20; 95% CI -0.00 to 0.39). The NAFLD Activity Score was significantly improved after both procedures, as well as biochemical tests. No difference was found between RYGB and SG regarding the histopathological outcomes. SG and RYGB are equivalently effective for treating NAFLD/NASH.

Abstract
Context: Some studies have shown that one anastomosis gastric bypass (OAGB) results in the derangement of liver function tests (LFTs). We wanted to study this in our patients. Aims: The aims are to study the effect of OAGB on LFTs and to compare the effect of a biliopancreatic limb (BPL) of 150 cm (OAGB-150) to a BPL of 200 cm (OAGB-200). Settings and Design: The study was a retrospective cohort study conducted at a university hospital. Materials and Methods: Information was obtained from our prospectively maintained database and hospital's computerised records. Statistical Analysis: A P < 0.05 was regarded statistically significant; however, given the number of variables examined, findings should be regarded as exploratory. Results: A total of 405 patients underwent an OAGB-200 (n = 234) or OAGB-150 (n = 171) in our unit between October 2012 and July 2018. There were significant improvements in gamma-glutamyl transpeptidase (GGT) levels at 1 and 2 years after OAGB-200 and significant worsening in the levels of alkaline phosphatase (ALP) and albumin at 1 and 2 years. There was a significant improvement in GGT levels at 1 and 2 years after OAGB-150 and in alanine transaminase levels at 1 year. There was a significant worsening in ALP and albumin levels at both follow-up points in this group. OAGB-150 group had a significantly lower bilirubin level at 1 year and significantly fewer abnormal ALP values at 2 years in comparison with OAGB-200 patients. Conclusions: This exploratory study demonstrates the overall safety of OAGB with regard to its effect on LFTs, with no remarkable difference between OAGB-150 and OAGB-200.

Abstract
Introduction Most Bariatric units perform Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) and One Anastomosis Gastric Bypass (OAGB) for weight loss and metabolic purposes with satisfactory results and low complication profile. Objectives This study compares LRYGB and OAGB outcomes in a high volume single bariatric unit. Methods Data was collected prospectively and analysed retrospectively for all LRYGB and OAGB performed between Jan 2014 to Dec 2016. The follow up period was for 2 years. Patients who were lost to follow up or had prior bariatric procedure were excluded. Excess weight loss percentage (EWL %), total weight loss percentage (TWL %) and post-operative complications were compared in both groups. Results 1268 procedures performed. 113 patients were excluded. At 2 years, for LRYGB and OAGB groups mean TWL % was 31% and 35.4% respectively (P < 0.0001); and mean EWL % was 70.1% and 74.8% respectively (P = 0.0119). Gastroesophageal reflux symptoms were higher in OAGB group 17 (8.5%), with 7 patients needing further surgery, versus 26 (2.7%) in LRYGB (P = 0.0003). There was no difference in incidence of marginal ulcers between LRYGB and OAGB 2.7% vs 5% respectively (P = 0.1115). Internal hernia was seen only in LRYGB patients, 22 (2.2%). There was no significant difference in the re-operation rates following LRYGB 52 (5.4%) and OAGB 16 (8%) (P = 0.1824). Conclusion OAGB had superior short-term weight loss and low complications profile. Both procedures demonstrated no difference in either marginal ulcers or re-operation rates. Reflux symptoms have remained a major side effect of OAGB. One anastomosis gastric bypass has shown to have a safe operative profile and effective weight loss outcomes. No difference in marginal ulcerations or reoperation rate between One anastomosis gastric bypass and Laparoscopic Roux en y. We recommend strict selection criteria for patient undergoing OAGB.

Abstract
INTRODUCTION We aim to review the available literature on morbidly obese patients treated with one anastomosis gastric bypass (OAGB) or Roux-en-Y gastric bypass (RYGB) in order to compare the clinical outcomes of the two methods. METHODS A literature search was performed in PubMed, Cochrane Library, and Scopus, in accordance with the PRISMA guidelines. RESULTS Sixteen studies were included in the qualitative analysis, and 11 studies were included in the quantitative analysis (meta-analysis), incorporating 12,445 patients. OAGB was associated with shorter mean operative time. The length of hospital stay was comparable between the two procedures. The incidence of leaks, marginal ulcer, dumping, bowel obstruction, revisions, and mortality was similar between the two approaches. The incidence of malnutrition was increased in patients treated with OAGB, while the incidence of internal hernia and bowel obstruction was greater in the RYGB group. In addition, the OAGB was associated with greater % excess weight loss (%EWL) at 1, 2, and 5 years postoperatively. The rate of diabetes remission was greater in the OAGB group. Nonetheless, the rate of hypertension and dyslipidemia remission was similar between OAGB and RYGB. CONCLUSION The present meta-analysis is the best currently available evidence on the topic and demonstrates the superiority of OAGB compared with RYGB, in terms of weight loss and diabetes remission. However, the OAGB was associated with a significantly higher incidence of malnutrition, thus indicating the significant malabsorptive traits of this operation.

Abstract
BACKGROUND Patients with morbid obesity commonly have fatty liver disease and elevated liver enzymes. While surgery effectively induces weight loss, bariatric techniques may differ regarding liver function improvement. OBJECTIVES To evaluate and compare the trends of liver function recovery after gastric bypass surgery (GB) with sleeve gastrectomy (SG). SETTING University hospitals, Iran. METHODS Adult bariatric candidates without a history of alcohol consumption or other etiologies of liver disease who underwent SG (n = 682) or GB (n = 355) were included. Trends of weight loss parameters and alanine transaminase (ALT), aspartate transaminase (AST), and alkaline phosphatase (ALP) at 0, 6 (in 90.4%), 12 (in 83.5%), and 24 months (in 67.1%) were compared using generalized estimating equations method. RESULTS Overall, 1037 patients with mean age of 38.4 ± 11.2 and mean body mass index of 44.9 ± 6.2 kg/m2 were analyzed. Seventy-eight percent of patients had fatty liver by ultrasound. Both GB and SG patients lost significant weight, with GB patients having a higher percentage of excess weight loss at 24 months (80.1% vs. 75.9%, Pbetween-group = .008). SG patients showed more favorable trends in liver chemistries with significantly lower ALT at 12 months and AST and ALP levels at 6 and 12 months. However, the two groups were comparable at 24 months. Significantly more GB patients developed high ALT at 6 and high AST at 6 and 12 months. Undergoing GB was associated with smaller 0-12-month changes in ALT, AST, and ALP. CONCLUSIONS Bariatric surgery resulted in improvement in liver function parameters, with SG showing advantages over GB in the first postoperative year.

Abstract
Abstract
Background
Obesity is closely linked to increased markers of metabolic syndrome and development of diabetes. Roux-en-Y bariatric surgery reduces hyperinsulinemia and improves insulin sensitivity and hence benefits morbidly obese patients.
Aim
To determine changes in markers of metabolic syndrome, pancreatic function, and hepatic insulin sensitivity in patients before and 1 year after undergoing Roux-en-Y gastric bypass surgery.
Methods
We enrolled 43 consecutive patients in a single center. Markers for metabolic syndrome included proinsulin, insulin, C-peptide, liver enzymes, and serum levels of selected microRNAs hsa-miR-122, hsa-miR-130, hsa-miR-132, and hsa-miR-375.
Results
After surgery, all patients showed a significant 37% drop of body mass index (p < 0.001). Furthermore, proinsulin (59% reduction, p < 0.001), insulin (76% reduction, p < 0.001), and C-peptide (56% reduction, p < 0.001) were all reduced 1 year after surgery. Using the hepatic insulin clearance score, we determined a significant increase in hepatic insulin clearance after surgery (76% increase, p < 0.001). Especially diabetic patients showed a marked 2.1-fold increase after surgery. Hepatic enzymes ALT (35% reduction, p = 0.002) and γGT (48% reduction, p < 0.001) were significantly reduced in all patients with similar improvement in diabetic and non-diabetic patients. miRNAs hsa-miR-122, hsa-miR-130, and hsa-miR-132 were all significantly reduced whereas hsa-miR-375 was increased after gastric bypass surgery (p < 0.001 for all miRNAs).
Conclusion
Both liver and pancreatic stress parameters were reduced significantly 1 year after Roux-en-Y gastric bypass surgery suggesting an overall amelioration of the metabolic syndrome in all patients regardless of previous health status.

Abstract
BACKGROUND Bariatric surgery contributes to the improvement in glucose metabolism that may be related to a postoperative increase in serum bile acids (BAs). Three commonly used types of bariatric procedures, laparoscopic sleeve gastrectomy (LSG) (without creation of a bile loop), Roux-en-Y gastric bypass (RYGB), and omega-loop gastric bypass (OLGB) (with creation of shorter 100-150 cm and longer 200-280 cm bile loops, respectively), differ in their effects on glycemic control. The aim of the study was to compare the effects of various bariatric procedures on serum BA concentration and glucose homeostasis. METHODS Serum BAs in 26 obese patients were determined by liquid chromatography-mass spectrometry prior to bariatric surgery, as well as 4 days and 3 months thereafter. RESULTS Four days after the surgery, serum concentrations of BAs in LSG and OLGB groups were similar as prior to the procedure, and a slight decrease in serum BAs was observed in the RYGB group. Serum BA level in the LSG group remained unchanged also at 3 months after the surgery, whereas a significant 0.5- and 3-fold increase in this parameter was noted in the RYGB and OLGB groups, respectively. Serum concentration of BAs correlated positively with the length of the bile loop (R = 0.47, p < 0.05). CONCLUSION The evident improvement of glycemic control observed 3 months after OLGB might be associated with a postoperative increase in serum BAs, resulting from their better absorption from the longer bile loop. However, the changes in serum BAs probably had little or no impact on insulin sensitivity improvement at 4 days post-surgery.

Abstract
PREAMBLE The International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) has played an integral role in educating both the metabolic surgical and the medical community at large about the role of innovative and new surgical and/or endoscopic interventions in treating adiposity-based chronic diseases.The mini gastric bypass is also known as the one anastomosis gastric bypass. The IFSO has agreed that the standard nomenclature should be the mini gastric bypass-one anastomosis gastric bypass (MGB-OAGB). The IFSO commissioned a task force (Appendix 1) to determine if MGB-OAGB is an effective and safe procedure and if it should be considered a surgical option for the treatment of obesity and metabolic diseases.The following position statement is issued by the IFSO MGB-OAGB task force and approved by the IFSO Scientific Committee and Executive Board. This statement is based on current clinical knowledge, expert opinion, and published peer-reviewed scientific evidence. It will be reviewed in 2 years.

Abstract
Nonalcoholic fatty liver disease (NAFLD) prevalence is rising worldwide, as a direct consequence of the obesity epidemic. Bariatric surgery provides proven NAFLD amelioration, although questions remain regarding whether Roux-en-Y gastric bypass (RYGB) or laparoscopic sleeve gastrectomy (LSG) is more effective. To answer this question, we conducted a systematic review and meta-analysis exclusively comparing RYGB and LSG for amelioration of NAFLD using 4 separate criteria: alanine transaminase, aspartate transaminase, NAFLD activity score, and NAFLD fibrosis score. Our search included 1290 initial studies, which were narrowed to 20 final studies in the meta-analysis. Overall, both RYGB and LSG significantly improved alanine transaminase, aspartate transaminase, NAFLD activity score, and NAFLD fibrosis score postoperatively. Direct comparisons of RYGB to LSG in any of the 4 criteria failed to demonstrate superiority. Our findings corroborate the current literature showing that bariatric surgery significantly improves biochemical and histologic parameters in patients with NAFLD. The novel individual comparisons of 4 criteria failed to show superiority between RYGB and LSG in ameliorating NAFLD. Despite several limitations, our study can assist clinicians by supporting the notion that RYGB and LSG may be equally efficacious in ameliorating NAFLD.

Abstract
Bariatric surgery (BS) is effective in treating morbid obesity, but the impact of prior BS on candidacy for liver transplantation (LT) is unclear. We examined 78 patients with cirrhosis with prior BS compared with a concurrent cohort of 156 patients matched by age, Model for End-Stage Liver Disease score, and underlying liver disease. We compared rates of transplant denial after evaluation, delisting on the waiting list, and survival after LT. The median time from BS to LT evaluation was 7 years. Roux-en-Y gastric bypass was the most common BS procedure performed (63% of cohort). Nonalcoholic fatty liver disease was the leading etiology for liver cirrhosis (47%). Delisting/death on the waiting list was higher among patients with BS (33.3% versus 10.1%; P = 0.002), and the transplantation rate was lower (48.9% versus 65.2%; P = 0.03). Intention-to-treat (ITT) survival from listing to 1 year after LT was lower in the BS cohort versus concurrent cohort (1-year survival, 84% versus 90%; P = 0.05). On adjusted analysis, a history of BS was associated with an increased risk of death on the waiting list (hazard ratio [HR], 5.7; 95% confidence interval [CI], 2.2-15.1), but this impact was attenuated (HR, 4.9; 95% CI, 1.8-13.4) by the presence of malnutrition. When limited to matched controls by sex, mortality attributed to BS was no longer significant for females (P = 0.37) but was significant for males (P = 0.046). Sarcopenia, as captured by skeletal muscle index, was calculated in a subset of patients (n = 49). The total skeletal surface area was lower in the BS group (127 [105-141] cm2 versus 153 [131-191] cm2 ; P = 0.005). Rates of sarcopenia were higher among patients delisted after listing (71.4% versus 16.7%; P = 0.04). In conclusion, a history of BS was associated with higher rates of delisting on the waiting list as well as lower survival from the time of listing on ITT analysis. Presence of malnutrition and sarcopenia among patients with BS may contribute to worse outcomes.

Abstract
We aim to review the available literature on morbidly obese patients treated with one anastomosis gastric bypass (OAGB) or Roux-en-Y gastric bypass (RYGB) in order to compare the clinical outcomes of the two methods. A literature search was performed in PubMed, Cochrane library and Scopus, in accordance with the PRISMA guidelines. Twelve studies met the inclusion criteria (7452 patients). OAGB was associated with shorter mean operative time. The length of hospital stay was comparable between the two procedures. The incidence of leaks, marginal ulcer, dumping, bowel obstruction, revisions and mortality was similar between the two approaches. The incidence of malnutrition was increased in patients treated with OAGB, while the incidence of internal hernia and bowel obstruction was greater in the RYGB group. In addition, the percentage excess weight loss at 1, 2 and 5 years post-operatively was greater for the OAGB group. The rate of type 2 diabetes remission was greater in the OAGB group. The rate of hypertension and dyslipidemia remission was also similar between OAGB and RYGB. Randomized controlled trials, comparing RYGB to OAGB, are necessary to further assess their clinical outcomes.

Abstract
There is no consensus on the monitoring of liver function tests after Roux-en-Y gastric bypass (RYGB). Since the main objective of such monitoring would be to diagnose early those who will eventually develop liver failure after RYGB, we performed a systematic review on this topic. An extensive search of literature revealed only 10 such cases in 6 published articles. It would hence appear that liver failure is a rare problem after RYGB. Routine lifelong monitoring of liver function tests is therefore unnecessary for otherwise asymptomatic individuals. Such monitoring should hence be reserved for high-risk groups, such as patients with liver cirrhosis, those undergoing extended limb/distal RYGB, patients with new illnesses, those abusing alcohol, those on hepatotoxic drugs and those presenting with a surgical complication.

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.

Abstract
Performance of MGB with a 200 cm bypassed limb in a morbidly obese female. Presentation of anemia, low albumin, elevated LFT at 8th month despite good intake. NAFLD activity score progressed from 2/8 to 7/8, leading to revisional surgery. Rapid course of weight loss after BS and/or long bypassed limb could be responsible. Bowel length measurement is recommended to avoid a short common intestinal channel.
Introduction Mini-gastric bypass (MGB) is a popular bariatric procedure. Its effect on non-alcoholic fatty liver disease (NAFLD), however, has not yet been comprehensively studied. Presentation of case A 57 year-old non-alcoholic female with a body mass index of 42.8 kg/m2 underwent MGB without any incident. A concurrent liver biopsy showed an NAFLD activity score (NAS) of 2/8 without fibrosis. She presented at postoperative month eight with edema, vague abdominal pain, nausea, and vomiting and was hospitalized. Her BMI had dropped to 25.7 kg/m2. Her blood workup revealed mild anemia, mildly elevated liver enzymes, and hypoalbuminemia (2.5 g/dL). Liver ultrasound revealed grade-2 fatty liver. She received parenteral nutrition and intensive nutrient supplementation. Nevertheless, with regard to unsuccessful supportive measures and rising liver enzymes, revisional surgery −gastrogastrostomy- was performed. Her liver biopsy demonstrated a NAS of 7/8 at the time of revisional surgery. Her postoperative course was uneventful and she was discharged after one week. Discussion Bariatric surgery has shown favorable results regarding improvement of NAFLD in morbid obesity. This beneficial effect has been linked to the amount of weight loss. However, case reports have shown deteriorating liver function and NAFLD even after significant weight loss. They all have in common significant weight loss in a relatively short period of time. There may also be a connection between specific bariatric surgery procedures and this phenomenon. Conclusion Future studies comparing the effect of various bariatric procedures, including MGB, are necessary to help clinicians decide the optimal procedure for patients with this liver condition.

Abstract
INTRODUCTION Mini-gastric bypass (MGB) is a bariatric surgical technique popular in many centers due to shorter duration, easier technique, and excellent weight loss results. However, it may be associated with postoperative malnutrition. This case describes the clinical course and unfortunate outcome of a morbidly obese patient who underwent MGB and developed malnutrition in the first postoperative year. PRESENTATION OF CASE A 37 year-old female patient with a BMI of 44kg/m2 successfully underwent MGB surgery in June 2015 and was discharged uneventfully. She presented with lower extremity edema and generalized weakness 8 months later, with a blood albumin level of 3.1g/dL, compared to a normal preoperative value. She was admitted and received a high-protein diet, and her clinical condition improved. Three months after her discharge, she was readmitted with the same complaints, as well as pancytopenia. She was also hypocupremic. After unsuccessful intensive supportive measures, she finally underwent revisional gastrogastrostomy. However, she developed signs and symptoms of profound liver failure postoperatively (albumin 1.8g/dL; total bilirubin 7.5mg/dL; prothrombin time 34s) and pancytopenia persisted. All resuscitative measures were unsuccessful and she expired in July 2016. DISCUSSION Multiple factors can contribute to postoperative malnutrition and liver dysfunction after MGB, including the presence of baseline liver disease, inadequate diet supplementation, leaving a too-short common small intestinal channel, and ethnic variations in small bowel length. These factors should also be considered when deciding to perform corrective surgery. CONCLUSION Careful, individualized treatment and follow-up plans may help to prevent such catastrophic consequences.
