Abstract
INTRODUCTION One anastomosis gastric bypass (OAGB) prevalence is increasing worldwide and shows good mid- to long-term results. Data on long-term outcomes of revisional OAGB (rOAGB) is limited. This study's objective was to evaluate the long-term outcomes of patients undergoing primary OAGB (pOAGB) and rOAGB. METHODS A retrospective analysis of a prospectively maintained patient registry at a single-tertiary center. Patients undergoing OAGB from January 2015 to May 2016 were included and grouped into pOAGB and rOAGB. RESULTS There were 424 patients, of which 363 underwent pOAGB, and 61 underwent rOAGB. Baseline characteristics were insignificantly different between groups except for the type 2 diabetes (T2D) rate which was higher in pOAGB (26% vs. 11.5%, p = 0.01). The mean follow-up time was 98.5 ± 3.9 months, and long-term follow-up data were available for 52.5% of patients. The mean total weight loss (TWL) was higher in the pOAGB group (31.3 ± 14 vs. 24.1 ± 17.6, p = 0.006); however, TWL was comparable when relating to the weight at primary surgery for rOAGB. The rate of T2D and hypertension resolution was 79% and 72.7% with no difference between groups. Thirteen patients (5.9%) underwent OAGB revision during follow-up, with no difference between groups. Two deaths occurred during follow-up, both non-related to OAGB. CONCLUSION OAGB is effective as a primary and as a revisional procedure for severe obesity with good long-term results in terms of weight loss and resolution of associated diseases. In addition, the revisional surgery rates and chronic complications are acceptable. Further large prospective studies are required to clarify these data.

Updates Surg 2024:10.1007/s13304-024-01820-8. [PMID: 38594580 DOI: 10.1007/s13304-024-01820-8] [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: 05/04/2023] [Accepted: 03/04/2024] [Indexed: 04/11/2024]
Abstract
The study aimed to evaluate the mid-term weight loss outcomes and complications of revisional one-anastomosis gastric bypass (OAGB) following failed laparoscopic sleeve gastrectomy (LSG). A total of 586 patients underwent LSG from January 2010 to February 2018. Revisional OAGB (rOAGB) was performed in 22 (3.8%) patients. A retrospective analysis of prospectively collected data from 20 patients with at least 12 months of follow-up after the revisional OAGB was carried out. The indications for revisional surgery were as follows: insufficient weight loss-4 (20%), weight regain-13 (65%), weight regain and symptoms of gastroesophageal reflux disease (GERD)-2 (10%), and dysphagia with gastroesophageal reflux-1 (5%). The mean interval between the LSG and rOAGB was 35.3 ± 15.4 months (range 4-64). The mean follow-up time after rOAGB was 45.5 ± 17.1 months (range 12-54). At the end of the follow-up after rOAGB, %TWL was 26.4 ± 8.9%, and %EWL was 58.5 ± 21.6%, based on pre-LSG body weight. In all three patients with intractable GERD, the clinical symptoms of reflux retreated after revisional OAGB. The overall complication rate was 20%. In conclusion, the main indications for revision after LSG are weight regain, insufficient weight loss, and intractable GERD. Revisional OAGB emerges as a viable surgical alternative for unsuccessful LSG, presenting notable weight loss outcomes; however, it may be linked to an increased incidence of complications.

Obes Surg 2024; 34:77-85. [PMID: 37964164 PMCID: PMC10781856 DOI: 10.1007/s11695-023-06928-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 10/24/2023] [Accepted: 10/24/2023] [Indexed: 11/16/2023]
Abstract
INTRODUCTION One anastomosis gastric bypass (OAGB) is one option of a revisional procedure for failed sleeve gastrectomy. Moreover, it can be used as a primary bariatric procedure, and is an effective surgery resulting in significant weight loss and the resolution or improvement of obesity-associated medical problems, accompanied by low perioperative complications. However, as with any therapy, OAGB has its limitations, including micronutrient deficiency or malnutrition. In our study, we compared the fatty acid (FA) profile in serum of patients after both primary OAGB (pOAGB) and revisional OAGB (rOAGB) to identify potential postsurgical FA alterations. METHODS This is a retrospective study on patients with obesity who underwent OAGB procedures (pOAGB n=68; rOAGB n=17), conducted from 2016 to 2018. In blood, we analyzed a series of biochemical parameters, and in the serum, the FA profile was determined using gas chromatography-mass spectrometry. RESULTS The percentage of excess BMI loss (% EBMIL) after pOAGB was 73.5 ± 2.47% in comparison to 45.9 ± 4.15% in the rOAGB group (p<0.001). In contrast to the lack of effect of rOAGB on most polyunsaturated FAs, in the pOAGB group, there was a decrease in eicosapentaenoic acid, and eicosatetraenoic and docosahexaenoic acid levels (p<0.001). We also found a decrease in very long-chain FAs (VLCFAs) and an increase in branched-chain FAs (BCFAs) after both types of OAGB procedure. CONCLUSIONS Both OAGB procedures improved the profile of most FAs, leading to a decrease in VLCFAs, which are considered harmful, and an improvement in BCFAs, which are considered to be beneficial. There is a need to further investigate the possibility of n-3 polyunsaturated FA supplementation after pOAGB, due to the large decrease in these FAs after pOAGB.

Roux-en-Y Gastric Bypass Versus One Anastomosis Gastric Bypass as Revisional Surgery After Failed Sleeve Gastrectomy: A Systematic Review and Meta-analysis. JOURNAL OF METABOLIC AND BARIATRIC SURGERY 2023; 12:57-66. [PMID: 38196783 PMCID: PMC10771971 DOI: 10.17476/jmbs.2023.12.2.57] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Revised: 11/22/2023] [Accepted: 11/22/2023] [Indexed: 01/11/2024]
Abstract
Purpose This study aimed to assess the outcomes of revisional procedures, namely Roux-en-Y gastric bypass (RYGB) and one anastomosis gastric bypass (OAGB) following unsuccessful laparoscopic sleeve gastrectomy. Materials and Methods This systematic review and meta-analysis included 817 patients (404 in OAGB group, 413 in RYGB group) from seven retrospective comparative studies. Data on sample size, demographics, perioperative complications, operative time, pre- and post-revisional body mass index, total weight loss, and global weight loss over follow-up were extracted. Results The mean operative time was 98.2-201 minutes for RYGB versus 78.7-168 minutes for OAGB. Despite classical RYGB gastric bypass taking longer, mini gastric bypass resulted in greater weight loss than RYGB, with a mean difference of -5.84 (95% confidence interval [CI], -6.74 to -4.94; P<0.00001; I2=0%), greater total weight loss, and a higher diabetes remission rate (odds ratio [OR], 0.32; 95% CI, 0.14 to 0.71). However, OAGB was associated with a significantly higher incidence of postoperative gastroesophageal reflux than RYGB (52 vs. 31: OR, 0.40; 95% CI, 0.24 to 0.67; P=0.0005; I2=0%). Conclusion OAGB was performed more quickly and boasted greater total weight loss and higher diabetes remission rates compared to RYGB after failed sleeve gastrectomy. However, OAGB also demonstrated a higher incidence of postoperative gastroesophageal reflux disease. Thus, careful patient selection is essential when considering OAGB.

Abstract
This systematic review and meta-analysis aimed to investigate the incidence of new-onset gastroesophageal reflux, reflux change, esophagitis, Barrett's esophagus, and revision due to reflux, gastritis, and marginal ulcer after one-anastomosis gastric bypass (OAGB). We performed subgroup analyses based on primary and revisional OAGB and time of follow-up. Meta-analysis of 87 studies with 27,775 patients showed a 6% rate of new-onset reflux after OAGB. Preoperative reflux status did not change significantly after OAGB. The rate of esophagitis and Barrett's esophagus was 15% and 1%, respectively. The new-onset reflux rate after OAGB was significantly higher than gastric bypass but not different with sleeve gastrectomy. The current study showed a relatively low rate of reflux and its complications after OAGB, but it was significantly higher than Roux-en-Y gastric bypass.

Abstract
INTRODUCTION The aim of this study was to compare weight loss and gastroesophageal reflux disease (GERD) remission after one-anastomosis gastric bypass (OAGB) versus Roux-en-Y gastric bypass (RYGB) as revisional procedures after laparoscopic sleeve gastrectomy (LSG). METHODS In PubMed, Embase, and Cochrane Library, a search was performed using the terms "Roux-en-Y gastric bypass versus one anastomosis gastric bypass," "revisional surgery," and "sleeve gastrectomy." Only original articles in English language comparing OAGB and RYGB were included. No temporal interval was set. The primary outcome measure was weight loss (%TWL). The secondary endpoints were leak, bleeding, marginal ulcer, and GERD. PRISMA flowchart was used. Differences in continuous and dichotomous outcome variables were expressed as mean difference (MD) and risk difference (RD) with 95% CI, respectively. Heterogeneity was assessed by using I2 statistic. RESULTS Six retrospective comparative articles were included in the present meta-analysis. Weight loss analysis showed a MD = 5.70 (95% CI 4.84-6.57) in favor of the OAGB procedure with a statistical significance (p = 0.00001) and no significant statistical heterogeneity (I2 = 0.00%). There was no significant RD for leak, bleeding, or marginal ulcer after the two revisional procedures. After conversion to OAGB, remission from GERD was 68.6% (81/118), and it was 80.6% (150/186) after conversion to RYGB with a RD = 0.10 (95% CI -0.04, 0.24), no statistical significance (p = 0.19), and high heterogeneity (I2 = 96%). De novo GERD was 6.3% (16/255) after conversional OAGB, and it was 0.5% (1/180) after conversion to RYGB with a RD = -0.23 (95% CI -0.57, 0.11), no statistical significance (p = 0.16), and high heterogeneity (I2 = 92%).

Best practice approach for redo-surgeries after sleeve gastrectomy, an expert's modified Delphi consensus. Surg Endosc 2023; 37:1617-1628. [PMID: 36693918 DOI: 10.1007/s00464-023-09879-x] [Citation(s) in RCA: 12] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2022] [Accepted: 01/08/2023] [Indexed: 01/26/2023]
Abstract
BACKGROUND Sleeve gastrectomy (SG) is the most common metabolic and bariatric surgical (MBS) procedure worldwide. Despite the desired effect of SG on weight loss and remission of obesity-associated medical problems, there are some concerns regarding the need to do revisional/conversional surgeries after SG. This study aims to make an algorithmic clinical approach based on an expert-modified Delphi consensus regarding redo-surgeries after SG, to give bariatric and metabolic surgeons a guideline that might help for the best clinical decision. METHODS Forty-six recognized bariatric and metabolic surgeons from 25 different countries participated in this Delphi consensus study in two rounds to develop a consensus on redo-surgeries after SG. An agreement/disagreement ≥ 70.0% on statements was considered to indicate a consensus. RESULTS Consensus was reached for 62 of 72 statements and experts did not achieve consensus on 10 statements after two rounds of online voting. Most of the experts believed that multi-disciplinary team evaluation should be done in all redo-procedures after SG and there should be at least 12 months of medical and supportive management before performing redo-surgeries after SG for insufficient weight loss, weight regain, and gastroesophageal reflux disease (GERD). Also, experts agreed that in case of symptomatic GERD in the presence of adequate weight loss, medical treatment for at least 1 to 2 years is an acceptable option and agreed that Roux-en Y gastric bypass is an appropriate option in this situation. There was disagreement consensus on efficacy of omentopexy in rotation and efficacy of fundoplication in the presence of a dilated fundus and GERD. CONCLUSION Redo-surgeries after SG is still an important issue among bariatric and metabolic surgeons. The proper time and procedure selection for redo-surgery need careful considerations. Although multi-disciplinary team evaluation plays a key role to evaluate best options in these situations, an algorithmic clinical approach based on the expert's consensus as a guideline can help for the best clinical decision-making.
