Carandina S, Soprani A, Sista F, De Palma M, Murcia S, Sartori A, Silvia F, Nedelcu A, Zulian V, Nedelcu M. Conversion of one-anastomosis gastric bypass (OAGB) to Roux-en-Y gastric bypass (RYGB) for gastroesophageal reflux disease (GERD): who is more at risk? A multicenter study. Surg Endosc 2024; 38:1163-1169. [PMID: 38082009 DOI: 10.1007/s00464-023-10611-y] [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: 08/27/2023] [Accepted: 11/26/2023] [Indexed: 02/23/2024]
Abstract
BACKGROUND Although gastroesophageal reflux disease (GERD) affects 0.6% to 10% of patients operated on for one-anastomosis gastric bypass (OAGB), only about 1% require surgery to convert to Roux-en-Y gastric bypass (RYGB) [3-5]. The aim of the present study was to analyze the characteristics of OAGB patients converted to RYGB for GERD not responding to medical treatment. METHODS This retrospective multicenter study included patients who underwent conversion from OAGB to RYGB for severe GERD. The conversion was performed with resection of the previous gastro-jejunal anastomosis and the use of the afferent loop as a new biliary loop. RESULTS A total of 126 patients were included in the study. Of these patients, 66 (52.6%) had a past medical history of bariatric restrictive surgery (gastric banding, sleeve gastrectomy). A hiatal hernia (HH) was present in 56 patients (44.7%). The association between previous restrictive surgery and HH was recorded in 33 (26.2%) patients. Three-dimensional gastric computed tomography showed an average gastric pouch volume of 242.4 ± 55.1 cm3. Conversion to RYGB was performed on average 60 ± 35.6 months after OAGB. Seven patients (5.5%) experienced an early postoperative complication (4 patients grade IIIb and 3 grade IIb), and 3 (2.4%) a late complication. Patients showed further weight loss after RYGB conversion and an average of 24.8 ± 21.7 months after surgery, with a mean % of total weight loss (%TWL) of 6.9 ± 13.6 kg. From a clinical point of view, the problem of GERD was definitively solved in more than 90% of patients. CONCLUSIONS Situations that weaken the esogastric junction appear to be highly frequent in patients operated on for OAGB and converted to RYGB for severe reflux. Similarly, the correct creation of the gastric pouch could play an important role in reducing the risk of conversion to RYGB for GERD.

Outcomes of One-Anastomosis Gastric Bypass Conversion to Roux-en-Y Gastric Bypass for Severe Obesity: A Systematic Review and Meta-analysis. Obes Surg 2024; 34:976-984. [PMID: 38244169 PMCID: PMC10899303 DOI: 10.1007/s11695-023-07050-y] [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: 09/18/2023] [Revised: 12/28/2023] [Accepted: 12/29/2023] [Indexed: 01/22/2024]
Abstract
One-anastomosis gastric bypass (OAGB) is an effective procedure to treat severe obesity. However, conversion to Roux-en-Y gastric bypass (RYGB) is increasing. We therefore conducted a systematic review to determine the safety and efficacy associated with OAGB-RYGB conversion. A systematic search was conducted by three independent reviewers using Medline, Embase, and the Cochrane library following PRISMA guidelines. Six studies including 134 patients were selected who were undergoing OAGB-RYGB conversion. The most common indications were reflux (47.8%), malnutrition (31.3%), and inadequate weight loss (8.2%). Study outcomes demonstrated 100% resolution of bile reflux. Overall, there was medium-term weight gain of 0.61 BMI. OAGB to RYGB conversion leads to resolution of reflux symptoms. However, it is associated with weight regain, albeit this may be acceptable to patients to treat biliary reflux.

ReSleeve or revisional one anastomosis gastric bypass for failed primary sleeve gastrectomy with dilated gastric tube: a retrospective study. Surg Endosc 2024; 38:787-798.

Abstract
BACKGROUND Revisional bariatric surgery (RBS) has been increasingly performed due to weight loss failure (WLF). Many revisional procedures have been proposed after primary laparoscopic sleeve gastrectomy (pLSG) failure, including ReSleeve gastrectomy (ReLSG), and laparoscopic one anastomosis gastric bypass (LOAGB). Choosing the RBS post-pLSG failure represents a challenge. WLF without gastric tube (GT) dilation is undoubtedly converted to a malabsorptive procedure, but the presence of GT dilation makes it more difficult to select a RBS. This study aimed to compare two relatively simple revisional procedures after pLSG failure with dilated GT to help decision making on which procedure better done to which patient. METHODS Data of 52 patients who completed one year follow-up (FU) after their RBS (ReLSG: 27 or LOAGB: 25) for their failed pLSG were collected, assessed, correlated to weight loss (WL) and compared. RESULTS Mean operative time was 97 ± 18.4 min. with revisional LOAGB (RLOAGB) and 62 ± 11 min. with ReLSG. Six patients (11.5%) had seven postoperative procedure-specific complications. Significant hemorrhage occurred in three patients. Two cases of leakage were encountered with each procedure. LOAGB Patients had lower mean final weight (76.2 ± 10.5 vs 85.3 ± 13), lower mean Final BMI (26.4 ± 2.5 vs 29.7 ± 2.9) and higher mean percentage of excess weight loss (EWL%) (83.6 ± 13.5% vs 60.29 ± 14.6%). All RLOAGB patients and 77.8% of ReLSG patients had EWL% > 50%. RLOAGB patients had higher EWL% compared to ReLSG (p < 0.001). Insufficient WL (IWL) patients had higher EWL% compared to weight regain (WR) patients (p = 0.034). CONCLUSION Both procedures (RLOAGB and ReLSG) were relatively safe and effective in terms of WL. RLOAGB led to higher WL compared to ReLSG in all types of patients despite higher Caloric intake. IWL patients had more WL compared to WR patients. WL was not related to GT dilation type. Large-scale longer-FU studies are still needed. TRIAL REGISTRATION PACTR202310644487566 (retrospectively registered).

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
<b><br>Introduction:</b> The rate of revisional surgeries following sleeve gastrectomy (SG) has increased. One-anastomosis gastric bypass (OAGB) appears to have multiple advantages as a primary bariatric procedure. OAGB as revisional surgery is still being investigated.</br> <b><br>Aim:</b> Evaluation of the efficacy and safety of OAGB performed as a post-SG revisional surgery.</br> <b><br>Materials and methods:</b> A single-center, retrospective cohort study was conducted using a routinely collected database of adults undergoing revisional OAGB after SG. A survey of patients was conducted, obtaining information on changes in body weight and improvement in gastroesophageal reflux disease (GERD) and obesity-related diseases.</br> <b><br>Results:</b> The study group included 74 patients: 59 women (80%) and 15 men, mean age of 41.61 9.21 years. The most common indication for OAGB was weight regain. The follow-up was up to 7 years, the mean time was 3.58 1.21 years. The mean preoperative body mass index (BMI) was 40.38 6.15. All patients experienced significant weight loss, reaching a BMI of 33.61 (27.28- 37.13) at the last observation. After surgery, 35% of patients achieved successful weight loss and 48% of patients achieved remission or improvement of GERD.</br> <b><br>Conclusions:</b> Revisional OAGB seems to be a good alternative after a failed SG in terms of obesity-related disease recurrence, not of weight regain. Long-term follow-up revealed that only a third of patients achieved successful weight loss. When proposing revisional OAGB, the risk of complications - mainly anemia and the possibility of de novo GERD should be considered.</br>.

Role of Preoperative High-Resolution Manometry in the Identification of Patients at High Risk of Postoperative GERD Symptoms 1 Year After Sleeve Gastrectomy. Obes Surg 2023; 33:2749-2757. [PMID: 37466827 DOI: 10.1007/s11695-023-06732-x] [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: 04/24/2023] [Revised: 07/05/2023] [Accepted: 07/14/2023] [Indexed: 07/20/2023]
Abstract
PURPOSE Sleeve gastrectomy (SG) has become the most common bariatric procedure, but it is often characterized by the onset of postoperative gastroesophageal reflux disease (GERD). High-resolution manometry (HRM) is a useful tool to detect risk factors for GERD. The aim of this study was to evaluate preoperative manometric parameters as possible predictors of postoperative GERD. MATERIALS AND METHODS This was a monocentric retrospective study. We analyzed 164 patients, with preoperative esophagitis/GERD symptoms who underwent preoperative HRM and were submitted to SG (July 2020-February 2022). RESULTS Postoperative GERD was observed in 60 patients (36.6%): 41 of them (68%) already had preoperative GERD symptoms, whereas the remaining 19 patients (32%) developed postoperative symptoms. Female patients developed postoperative GERD in a significantly higher fraction of cases as compared to male patients (82% versus 18%; p < 0.001). DCI (distal contractile integral) was identified as the only HRM parameter correlating with the presence of GERD. Patients with DCI ≤ 1623 mmHg*cm*s developed postoperative GERD in 46% of cases (n = 43/94), as compared to 24% of cases (n = 17/70) among patients with DCI > 1623 mmHg*cm*s (p = 0.005). At multivariable analysis, female sex (OR 3.402, p = 0.002), preoperative GERD symptoms (OR 2.489, p = 0.013), and DCI ≤ 1623 mmHg*s*cm (OR 0.335, p = 0.003) were identified as independent determinants of postoperative GERD. CONCLUSION All the patients with preoperative risk factors for reflux, such as GERD symptoms or esophagitis on EGDS (esophagogastroduodenoscopy), should be considered for an HRM. Moreover, when a DCI ≤ 1623 mmHg*s*cm is found, a bariatric procedure different from SG might be considered.

Abstract
BACKGROUND The advantages and disadvantages of one-anastomosis gastric bypass (OAGB) with primary modified fundoplication using the excluded stomach ("FundoRing") is unclear. We aimed to assess the impact of this operation in a randomized controlled trial (RCT) and answer the next questions: (1) What the impact of wrapping the fundus of the excluded part of the stomach in OAGB on protection in the experimental group against developing de novo reflux esophagitis? (2) If preoperative RE could be improved in the experimental group? (3) Can preoperative acid reflux as measured by PH impedance, be treated by the addition of the "FundoRing"? METHODS The study design was a single-center prospective, interventional, open-label (no masking) RCT (FundoRing Trial) with 1-year follow-up. Endpoints were body mass index (BMI, kg/m2) and acid and bile RE assessed endoscopically by Los Angeles (LA) classification and 24-h pH impedance monitoring. Complications were graded by Clavien-Dindo classification (CDC). RESULTS One hundred patients (n = 50 FundoRingOAGB (f-OAGB) vs n = 50 standard OAGB (s-OAGB)) with complete follow-up data were included in the study. During OAGB procedures, patients with hiatal hernia underwent cruroplasty (29/50 f-OAGB; 24/50 s-OAGB). There were no leaks, bleeding, or deaths in either group. At 1 year, BMI in the f-OAGB group was 25.3 ± 2.77 (19-30) vs 26.48 ± 2.8 (21-34) s-OAGB group (p = 0.03). In f-OAGB vs s-OAGB groups, respectively, acid RE was seen in 1 vs 12 patients (p = 0.001) and bile RE in 0 vs 4 patients (p < 0.05). CONCLUSION Routine use of a modified fundoplication of the OAGB-excluded stomach to treat patients with obesity decreased acid and prevented bile reflux esophagitis significantly more effectively than standard OAGB at 1 year in a randomized controlled trial.

Abstract
PURPOSE Assess the subjective impact of gastro-esophageal reflux disease (GERD) symptoms on patients undergoing revision from laparoscopic sleeve gastrectomy (LSG) to one-anastomosis gastric bypass (OAGB) using the Reflux Disease Questionnaire for GERD (RDQ) and the GERD-health related quality of life score (GERD-HRQL), prior to- and following conversion. METHODS Patients undergoing revision from LSG to OAGB were prospectively followed between May 2015 and December 2020. Data retrieved included demographics, anthropometrics, previous bariatric history, time interval between LSG and OAGB, weight loss, and co-morbidities. Pre- and post-OAGB RDQ and GERD-HRQL questionnaires were obtained. In the case of sleeve dilatation, sleeve resizing was performed. RESULTS During the study period, 37 patients underwent revision from LSG to OAGB. Mean ages at LSG and pre-OAGB were 38 ± 11.74 and 46 ± 12.75, respectively. Median follow-up time was 21.5 months (range 3-65). All patients underwent sleeve resizing. RDQ and GERD-HRQL scores were obtained at a median of 14 months (range 3-51) between pre- and post-OAGB. Median RDQ score pre-OAGB vs post-OAGB was significantly reduced (30 (range 12-72) vs 14 (range 12-60), p = 0.007). All 3 parts of the GERD- HRQL questionnaires were significantly reduced between pre-OAGB and post-OAGB: Symptoms (20; 62.5% vs 10; 31.3%, p = 0.012), overall score (15 (0-39) vs 7 (0-28), p = 0.04) and subjective improvement (10; 31% vs 20; 62.5%, p = 0.025). CONCLUSION Conversion of LSG to OAGB showed subjective improvement of GERD symptoms both in RDQ and in GERD-HRQL.

Abstract
BACKGROUND One-Anastomosis Gastric Bypass (OAGB) is the third most common bariatric operation for patients with obesity worldwide. One concern about OAGB is the presence of acid and non-acid reflux in a mid- and long-term follow-up. The aim of this study was to objectively evaluate reflux and esophagus motility by comparing preoperative and postoperative mid-term outcomes. SETTING Cross-sectional study; University-hospital based. METHODS This study includes primary OAGB patients (preoperative gastroscopy, high-resolution manometry (HRM), and impedance-24 h-pH-metry) operated at Medical University of Vienna before 31st December 2017. After a mean follow-up of 5.1 ± 2.3 years, these examinations were repeated. In addition, history of weight, remission of associated medical problems (AMP), and quality of life (QOL) were evaluated. RESULTS A total of 21 patients were included in this study and went through all examinations. Preoperative weight was 124.4 ± 17.3 kg with a BMI of 44.7 ± 5.6 kg/m2, total weight loss after 5.1 ± 2.3 years was 34.4 ± 8.3%. In addition, remission of AMP and QOL outcomes were very satisfactory in this study. In gastroscopy, anastomositis, esophagitis, Barrett´s esophagus, and bile in the pouch were found in: 38.1%, 28.3%, 9.5%, and 42.9%. Results of HRM of the lower esophageal sphincter pressure were 28.0 ± 15.6 mmHg, which are unchanged compared to preoperative values. Nevertheless, in the impedance-24 h-pH-metry, acid exposure time and DeMeester score decreased significantly to 1.2 ± 1.2% (p = 0.004) and 7.5 ± 8.9 (p = 0.017). Further, the total number of refluxes were equal to preoperative; however, the decreased acid refluxes were replaced by non-acid refluxes. CONCLUSION This study has shown decreased rates of acid reflux and increased non-acid reflux after a mid-term outcome of primary OAGB patients. Gastroscopy showed signs of chronic irritation of the gastrojejunostomy, pouch, and distal esophagus, even in asymptomatic patients. Follow-up gastroscopies in OAGB patients after 5 years may be considered.

Obes Surg 2023; 33:611-622. [PMID: 36564618 PMCID: PMC9889439 DOI: 10.1007/s11695-022-06401-5] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 11/29/2022] [Accepted: 11/30/2022] [Indexed: 12/25/2022]
Abstract
The objective of this review is to systematically review the efficacy and safety outcomes of one anastomosis gastric bypass (OAGB) with Roux-en-Y gastric bypass (RYGB). From inception to July 4, 2022, a systematic literature search was performed using PubMed, Embase, and Cochrane Library for randomized clinical trials comparing OAGB with RYGB in obesity. A meta-analysis performed using the RevMan 5.4.1 software evaluations was completed. We identified 1217 reports; after exclusions, eight trials with a total of 931 patients were eligible for analysis. Compared with RYGB, OAGB had multiple advantageous indexes. Examples include percent of excess weight loss (%EWL) at 12 months (P = 0.009), body mass index (BMI) at 2 years (P < 0.00001), early postoperative complication (P = 0.04), remission of dyslipidemia (P < 0.0001), and operative time (P < 0.00001). No significant statistical difference was observed in BMI at 6 months, %EWL at 6 months, BMI at 12 months, percent of excess body mass index loss (%EBMIL) at 2 years, BMI at 5 years, intraoperative complications, late postoperative complications, remission of type 2 diabetes mellitus, and dyslipidemia or gastroesophageal reflux disease remission between OAGB and RYGB. OAGB is no less effective than RYGB; no significant differences in weight loss efficacy were observed, and more large and long-term randomized controlled trials are needed to verify this. In addition, studies have shown that OAGB has a shorter operation time, fewer early postoperative complications, and a shorter learning curve, making it easier for young surgeons to perform.

A Long-Term Comparative Study Between One Anastomosis Gastric Bypass and Sleeve Gastrectomy. J Gastrointest Surg 2023; 27:47-55. [PMID: 36376721 PMCID: PMC9877051 DOI: 10.1007/s11605-022-05515-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Accepted: 10/30/2022] [Indexed: 11/16/2022]
Abstract
BACKGROUND One anastomosis gastric bypass (OAGB) has become increasingly accepted in bariatric surgery and meanwhile represents the third most common procedure worldwide. While it shows promising weight loss results and comorbidity resolution, questions about issues such as reflux or nutritional deficiencies (ND) persist in the long term. On the other hand, the most frequently performed sleeve gastrectomy (SG) has to accept growing criticism regarding long-term results and reflux issues. There is a particular lack of long-term comparative data for both procedures. This study presents our long-term experience. METHODS We evaluated OAGB and SG patients retrospectively comparing for weight loss and resolution of comorbidities as well as perioperative and long-term complications in a follow-up period of 5 years. RESULTS Nine hundred eleven OAGB and 241 SG were included in the study. OAGB had a shorter operation time and hospital stay. Overall complication rate did not differ in both groups. Ulcers were more frequent in OAGB (7.7% vs. 1.7%, p = 0.001), whereas insufficient weight loss (IWL)/weight regain (WR) proved to be more prevalent in SG (25.7% vs. 6.4%, p < 0.001). The same held true for reflux (17.8% vs. 8.3%, p < .001). On the other hand, ND were more common in OAGB (20.0% vs. 12.0%, p = 0.005). Revisional surgery was more often indicated after SG. Analysis by linear mixed model showed that OAGB achieved a lower BMI/higher loss of BMI. Improvement of T2DM (94.6% vs. 85.2%, p = 0.008) and sleep apnea (88.8% vs. 78.8%, p = 0.01) was superior in OAGB. CONCLUSIONS OAGB had a superior effect on weight loss as well as improvement of T2DM and sleep apnea. Furthermore, long-term problems such as IWL/WR and reflux were more related to SG. On the other hand, a malabsorptive procedure such as OAGB showed a higher risk for ND. Our findings support the available data in the literature.

Abstract
INTRODUCTION Sleeve gastrectomy (SG) is currently the most commonly performed bariatric procedure worldwide. The aim of the present study was to evaluate the long-term efficacy of SG as a stand-alone bariatric procedure. METHODS A single-center retrospective analysis of 104 patients who underwent SG as a stand-alone bariatric procedure between January 2005 and December 2009. Weight loss, weight regain, remission or improvement of comorbidities and the new onset of comorbidities were the main outcomes of the study. RESULTS The percent excess body weight loss (%EBWL), percent excess body mass weight (BMI) loss (%EBMIL), and percent total body weight loss (%TBWL) were 59 ± 25, 69 ± 29, and 29 ± 12, respectively, after a mean follow-up of 13.4 years. At the last follow-up, nearly two thirds of patients (67.3%) had an %EBWL greater than 50. The percentage of patients who experienced significant weight regain ranged from 47 to 64%, depending on the definition used for weight regain. The rate of improvement or remission of hypertension, type 2 diabetes, dyslipidemia, obstructive sleep apnea, and degenerative joint disease at a mean follow-up of 13.4 years was 40%, 94.7%, 70%, 100%, and 42.9%, respectively. The new onset of gastroesophageal reflux disease (GERD) symptoms in the same period was 43%. CONCLUSION Our data supports that SG results in long-lasting weight loss in the majority of patients and acceptable rates of remission or improvement of comorbidities. Weight regain and GERD may be issues of particular concern during long-term follow-up after SG.

Abstract
BACKGROUND The One Anastomosis Gastric Bypass (OAGB) is a relatively novel procedure. Studies have demonstrated that it is at least as effective as other bariatric procedures but with fewer major complications and shorter operating time, yet OAGB is performed less partially due to a paucity of supportive evidence. We report the outcomes of a prospectively maintained database of patients undergoing laparoscopic OAGB. METHODS All OAGB procedures performed by two surgeons across two hospitals from 2016 to 2019 were recorded in a prospectively maintained database. Patients with at least 1 year of follow up were included in this study and missing data was obtained from patient records. The primary outcome was percentage excess weight loss (EWL). The secondary outcome was surgical complication rate. RESULTS Three hundred and twenty-five patients with a mean pre-operative body mass index of 43.3 kg/m2 were included. The majority (85.2%) had a biliopancreatic limb length of 150 cm. The median EWL was 74.2% and 79.4% of patients achieved at least 50% EWL. There were no deaths, the overall re-operation rate was 4.9% and 1.9% of patients developed stomal ulcers. Seven patients went on to have a Roux-en-Y conversion predominantly for symptomatic reflux. CONCLUSION OAGB leads to excellent weight loss and is at least as safe as more commonly performed procedures, it may be a suitable treatment for a greater number of patients than it is being offered to at present.

Abstract
Data comparing the occurrence of gastroesophageal cancer after gastric bypass procedures are lacking and are only available in the form of case reports. We perform in this study a systematic review and a meta-analysis of all the reported cases of gastroesophageal cancer following Roux-en-Y gastric bypass (RYGB) and loop gastric bypass-one anastomosis gastric bypass/mini gastric bypass (LGB-OAGB/MGB). We conducted a systematic review of all the reported cases in articles referenced in PubMed/Medline, Cochrane, and Scholar Google. Only cases of gastro-esophageal adenocarcinoma following RYGB or LGB-OAGB/MGB are included. Statistical analysis was done accordingly. Fifty cases were identified, along with 2 reported in this paper. Sixty-one percent (27/44) of the cancers after RYGB were in the gastric tube compared to 37.5% (3/8) after LGB-OAGB/MGB. This resulted in an odds ratio of 0.38 (p-value = 0.26), which failed to prove an increase in cancer occurrence in the gastric tube after LGB-MGB/OAGB compared to RYGB. The most common symptoms were dysphagia for cancers occurring in the gastric tube (15/30) and abdominal pain for those occurring in the excluded stomach (10/22). Twenty-nine/thirty of the cancers in the gastric tube were diagnosed by gastroscopy and 13/22 of the cancers in the excluded stomach were diagnosed by CT scan. Gastroesophageal cancers after gastric bypass procedures occur commonly in the excluded stomach where many are not identified by conventional means. Physician awareness and patient education as well as lifelong follow-up are essential for maintaining bypass surgeries on the beneficial side.

[PMID: 35037131 DOI: 10.1007/s11695-022-05892-6] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2021] [Revised: 01/07/2022] [Accepted: 01/11/2022] [Indexed: 12/19/2022]
Abstract
PURPOSE One-anastomosis gastric bypass (OAGB) may be associated with refractory gastroesophageal reflux disease (GERD). The nature of this GERD remains unclear. This complication can be treated either with an additional enteroenterostomy without shortening of gastric pouch (long biliopancreatic limb Roux-en-Y gastric bypass (L-BPL-RYGB)) or revision to conventional short biliopancreatic limb Roux-en-Y gastric bypass (S-BPL-RYGB). The objective of this study is to compare the aforementioned procedures in terms of efficacy on GERD symptoms. MATERIALS AND METHODS Retrospective analysis between October 2012 and June 2020. RESULTS Fifty-two patients underwent OAGB revision to S-BPL-RYGB (n = 21) or L-BPL-RYGB (n = 31) secondary to GERD. Investigation with pH impedance prior to revision was performed in 15 patients showing biliary reflux (BR) in 7 (46.6%), acid reflux (AR) in 6 (40%), and no confirmation in 2. Patients with AR had a revision to S-BPL-RYGB, whereas patients with BR underwent L-BPL-RYGB. Among the patients without pH metry results (n = 37), S-BPL-RYGB was performed for associated disabling digestive disorders or nutritional deficiencies. GERD was treated in 68% of patients with L-BPL-RYGB versus 95% of patients after S-BPL-RYGB. Patients, whose decision for revisional procedure was based on the results of pH impedance testing, did not reveal refractory GERD. CONCLUSION L-BPL-RYGB seems appropriate in patients with BR, whereas conversion to S-BPL-RYGB should be preferred if AR is present.

Abstract
BACKGROUND Aim of this study was to improve knowledge about the best conversional bariatric procedure following sleeve gastrectomy (SG). METHODS Data of conversional Roux-en-Y gastric bypass (RYGB) and of one anastomosis gastric bypass (OAGB) after SG were collected prospectively and analyzed retrospectively. Weight loss parameters, gastroesophageal reflux disease (GERD) and comorbidities outcomes were recorded. RESULTS Total of 123 patients (90 female, mean age 44 ± 0.9 years, mean body mass index (BMI) 42 ± 0.8 kg/m2) had either RYGB (n = 68) or OAGB (n = 55). Perioperative mortality was zero. Mean surgery time was significantly shorter for OAGB (168 ± 7.2 vs. 201 ± 6.8 min). Perioperative complication rates were not significantly (ns) different between RYGB and OAGB. Total body weight loss (TBWL) in RYGB and OAGB was 18 ± 2.2% and 18 ± 1.9% (12 months) and 18 ± 3.0% and 23 ± 2.6% (24 months; ns), respectively. Length of (individualized) biliopancreatic limb (BPL) correlated significantly with weight loss. Remission rates after 12 months of RYGB and OAGB for arterial hypertension (aHt) were 89% and 92%, for obstructive sleep apnea (OSAS) 56% and 82%, for Type 2 diabetes mellitus (T2DM) 100% and 92%, for osteoarthritis 64% and 85% and for GERD 89% versus 87% (ns), respectively. Nutritional deficiencies were comparable in RYGB (n = 11) and OAGB (n = 14) group (ns). CONCLUSION Both RYGB and OAGB are effective conversional procedures after SG, leading to comparable TBWL, BMI-loss and high remission rates of comorbidities including GERD. Significantly shorter operation times were in favor of OAGB. BPL, which was longer in OAGB was significantly related to higher %TBWL and %BMI-loss compared to RYGB.

Abstract
OBJECTIVE To compare the effect of RYGB and OAGB on patients after failed treatment of obesity by laparoscopic sleeve gastrectomy (LSG). STUDY DESIGN A case-control study based on a prospectively maintained database of reoperated patients after failed LSG, which included 33 patients who underwent RYGB conversion and 47 patients who underwent OAGB conversion. RESULT The mean %EBWL after a 5-year follow-up for RYGBc vs OAGBc was 84.04% vs 72.95% (p = 0.2176), respectively. Complete long-term diabetes remission was observed significantly more frequently in the OAGBc than in the RYGBc group (97.3% vs 33%; p = 0.035). There were no other statistically significant differences in the remission rate of comorbidities between RYGBc and OAGBc: hypertension 30% vs 27.3% (p = 0.261), dyslipidemia 83.3% vs 59.1% (p = 0.277), OSAS 100% vs 60% (p = 0.639), and GERD 40% vs 71.4% (p > 0.99), respectively. 7 patients were newly diagnosed with GERD after OAGBc and none after RYGBc. There were no statistically significant differences in the number of complications between the OAGBc and RYGB groups. The Comprehensive Complication Index was 17.85 (± IQR 29.6) in the OAGBc group and 14.92 (± IQR 21.75) in the RYGBc group (p = 0.375). CONCLUSION The authors recognized complete long-term type 2 diabetes remission after conversion surgery as the most relevant difference, where the OAGB variety was found superior for its better efficacy. Any other statistically significant differences in the consequences after both conversion procedures used after the failure of LSG have not been stated. Both methods therefore can be considered to complete the initial treatment, considering the preferences and individual burdens of the patients.

Abstract
BACKGROUND Patients with obesity having GERD usually undergo Roux-en-Y gastric bypass (RYGB) as the procedure of choice. However, the emergence of one anastomosis gastric bypass (OAGB) as a less time-consuming operation with fewer complications offers a potential option for these patients. STUDY DESIGN This randomized controlled trial included 80 patients (out of 457 screened) with mild-to-moderate GERD that were equally divided into two groups for OAGB and RYGB. GERD was diagnosed by 20-item questionnaire, upper endoscopy, 24-h pH monitoring, and manometry. Follow-up at 6 and 12 months was done. RESULTS No significant differences were found between the two groups regarding demographic data, comorbidities, and weight loss. OAGB had less operative time and fewer complications. Both procedures had comparable favorable effects in reducing the GERD symptoms evidenced by upper endoscopy, 24-h pH monitoring, and manometry. CONCLUSION OAGB is a promising bariatric procedure in weight loss for patients with obesity having mild-to-moderate GERD (up to grade B esophagitis by Los Angeles score). Furthermore, wide-scale studies and on more severe degrees of GERD are required to fully understand its benefits in GERD patients with obesity.

Abstract
Purpose Both primary and revisional bariatric surgery are on the rise due to global obesity pandemic. This study aimed to assess the indications for revision after one-anastomosis gastric bypass (OAGB) and the outcomes after laparoscopic conversion of OAGB to roux-en-y gastric bypass (RYGB). Materials and Methods Retrospective review on patients that had undergone conversion of OAGB to RYGB between June 2007-June 2019 in a tertiary bariatric center, followed by literature review. Results Out of 386 revisional bariatric surgery, a total of 14 patients underwent laparoscopic conversion of OAGB to RYGB. The mean age was 44.7 with 71% female. The mean pre-revision BMI was 29.2 kg/m2. The primary indications for revision were bile reflux (n=7), marginal ulcer (n=3), inadequate weight loss or weight regain (IWL/WR) (n=3) and protein-calorie malnutrition (n=1). Conversion of OAGB to RYGB was completed laparoscopically in all cases. The mean length of stay was 4.1 days. There was no intraoperative or early post-operative complication. The mean total weight loss (rTWL%) after revision at year one, year three and year five post-revision were 11.5%, 18.1% and 29.1%, respectively. All patients achieved resolution of bile reflux and marginal ulcer. There was no mortality in this cohort. Conclusion Bile reflux, marginal ulcer, IWL/WR and malnutrition were the main indications for revision after OAGB in this study. In concordance with the available evidence, laparoscopic conversion of OAGB to RYGB was safe and effective in dealing with late complications of OAGB.

Abstract
One of the roles of the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) is to provide guidance on the management of patients seeking surgery for adiposity-based chronic diseases. The role of endoscopy around the time of endoscopy is an area of clinical controversy. In 2018, IFSO commissioned a task force to determine the role of endoscopy before and after surgery for the management of adiposity and adiposity-based chronic diseases. The following position statement is issued by the IFSO Endoscopy in Bariatric/Metabolic Surgery Taskforce. It has been 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 regularly.

Abstract
Background Recent reports have demonstrated that de novo reflux and worsening of pre-existing symptoms occur after SG; concerns are still expressed about the risk of symptomatic biliary reflux gastritis and oesophagitis. The aim of our study was to investigate and compare the rate of postoperative acid and non-acid reflux following Mini-/One anastomosis gastric bypass (MGB/OAGB) and laparoscopic sleeve gastrectomy (LSG). Study design A prospective randomized open-label, controlled trial registered on clinicaltrial.gov (NCT number: NCT02987673) has been carried out to evaluate esophagogastric junction exposure to reflux in the first year after MGB/OAGB and LSG using high impedance manometry, endoscopy, and a validated questionnaire. Results A total of 58 individuals were eventually enrolled in this trial and represented the per-protocol population (n = 28 MGB/OAGB, n = 30 LSG). No difference was found between the two groups in terms of demographic characteristics, PAGI-SYM score, acid exposure time percent of the esophagus (AET%), esophagitis, and other HRiM and MII-pH data at baseline. Comparing MII-pH outcomes of the two groups, AET% resulted significantly higher after LSG at 12 months. Endoscopic findings showed a significant increase of esophagitis ≥ B in the LSG group after 1 year; postoperative esophagitis ≥ B resulted also significantly worsened after LSG when compared to MGB/OAGB. Conclusion Since AET% and rate of esophagitis are significantly higher after LSG when compared to MGB/OAGB, this procedure should be preferred in case of preoperative subclinical reflux or low grade (A) esophagitis.

Abstract
One anastomosis gastric bypass (OAGB)/mini gastric bypass is now considered to be a safe and efficient method for morbidly obese patients but has complications and adverse events such as other surgical procedures. The present paper outlines the need for and the nature of revisional surgery in the long-term following OAGB in accordance with the preferred reporting items for systematic reviews and meta-analysis guidelines. A literature search was carried out in PubMed. All articles on OAGB for which the authors described a patient needing revisional surgery in the long term after OAGB were examined.

Abstract
OBJECTIVE To examine the relationship between Edmonton Obesity Staging System (EOSS) and perioperative complications as well as surgical procedure. BACKGROUND The application of EOSS for the selection of patients with obesity is a more comprehensive measure of obesity-related diseases and a predictor of mortality than body mass index (BMI). METHODS This was a nationwide cohort study using prospectively inserted data from the German register for obesity and metabolic surgery StuDoQ|MBE. All patients undergoing sleeve gastrectomy (SG), Roux-en Y gastric bypass (RYGB), and one-anastomosis gastric bypass (OAGB) between February 2015 and July 2017 as a primary treatment for severe obesity were included. Data included gender, age, BMI, ASA score, EOSS, early postoperative complications next to the Clavien-Dindo grading system, readmission, and 30-day mortality. RESULTS A total of 9437 patients were included. The mean BMI was 49.5 kg/m2 ± 7.8 (range 35-103.5). The total postoperative complication rate was 5.3%, with the highest rate in EOSS 3 (7.8%) and 4 (6.8%). Thirty-day mortality was 0.2% with the highest mortality after SG in EOSS 3 (1.16%) and EOSS 4 (0.92%) (p = 0.0068). Crosstabs showed a prevalence of Clavien-Dindo III and IV complications of 3.4% (SG), 3.6% (RYGB), and 1.6% (OAGB) in EOSS 2 (p = 0.0032) and 3.5% (SG), 5.1% (RYGB), and 5.6% (OAGB) in EOSS 3. CONCLUSION The highest postoperative complications and mortality occurred in patients with EOSS ≥ 3. SG and OAGB could be the procedure of choice to reduce perioperative morbidity; nevertheless, it has to be in mind that in EOSS ≥ 3, SG has the highest mortality. TRIAL REGISTRATION ClinicalTrials.gov Identifier NCT03556059.

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
PURPOSE Gastric fistula is a severe complication following sleeve gastrectomy (SG). Chronic gastric fistula can progress to complex anatomical situations, such as esogastro-bronchial and/or esogastro-pleural (EGBP) fistulas. We decided to analyze the anatomical characteristics of these EGBP fistulas after SG. METHODS Our work consisted of an analysis of the clinical, endoscopic, and radiological data of patients treated for EGBP fistulas after SG at the Georges Pompidou European Hospital from May 2009 to November 2017. RESULTS A total of 11 patients were retrospectively included with available complete clinical, endoscopic, and radiological data. The origin of the fistula was mostly at the top of the staple line. The fistula's termination was pleural in 5 patients (45%) and bronchial in 6 (55%). In bronchial fistulas, 2 were proximal and 4 were distal, with the left pulmonary posterolateral segment (S10) being reached in each case. The trans-diaphragmatic passage was through the left cupola in 9 out of 11 patients (82%). In 2 patients, the passage was trans-hiatal (18%). Interestingly, the 2 eso-bronchial fistulas had a trans-hiatal passage with a termination in the proximal bronchus, while the 4 gastro-bronchial fistulas had a trans-diaphragmatic passage with a termination in the distal bronchus. All pleural fistulas were gastric with a trans-diaphragmatic passage. CONCLUSIONS Esogastro-bronchial and gastro-pleural fistulas after SG originated mostly at the top of the staple line. Eso-bronchial fistulas had a trans-hiatal passage with a proximal bronchial termination, while gastro-bronchial fistulas had a trans-diaphragmatic passage with a distal bronchial termination.

Abstract
BACKGROUND Whether one anastomosis gastric bypass (OAGB) or Roux-en-Y gastric bypass (RYGB) is a better revisional bariatric surgery (RBS) after sleeve gastrectomy (SG) is still under debate. The aim is to compare short-term outcomes of RYGB and OAGB as a RBS after SG, pertaining to their effects on weight loss, resolution of comorbidities, and complications. METHODS We performed a single-center analysis of 55 patients (n = 34 OAGB, n = 21 RYGB). Indications for revisional surgery included weight regain/loss failure (67%) and intractable gastroesophageal reflux disease (33%). Data were collected up to 1-year follow-up (FU) and included time of revisional surgery, operation time, weight, body mass index, excess weight loss, and total weight loss (TWL), both in percent, complications and resolution of comorbidities. RESULTS Operation time was 79 ± 36 (OAGB-MGB) and 98 ± 24 min (RYGB) (p = 0.03). In the first 30 postoperative days, three patients in the RYGB group, and no patient in the OAGB group, had postoperative complications. FU was 100%. Minor complication rates at 12 months were 33.3% (RYGB) and 35.3% (OAGB). At 12 months, mean % TWL was 10.3 ± 7.6% (RYGB) and 15.8 ± 7.8% (OAGB) (p = 0.0132). CONCLUSIONS OAGB after failed SG was found to be a quicker procedure with less perioperative complications. At 1-year FU, no significant differences were seen between RYGB and OAGB regarding readmission and minor complications. Still long-term FU including the risk of malnutrition is needed to have a complete evaluation of OAGB as a RBS for the future.

Abstract
BACKGROUND One-anastomosis gastric bypass (OAGB) is an accepted bariatric and metabolic surgery with certain important complications, such as postoperative gastroesophageal reflux disease (GERD) and bile reflux (BR), which are not well addressed in literature. OBJECTIVES The present study was conducted to determine the true incidence of postoperative de novo GERD and BR and their associations with a hiatal hernia (HH). SETTING The present research setting comprised the Center of Excellence of the European Branch of the International Federation for the Surgery of Obesity and Metabolic Disorders, Hazrat-e-Rasoul Hospital, Tehran, Iran. METHODS The present cohort study recruited 200 patients with morbid obesity undergoing OAGB/minigastric bypass from December 2016 to February 2018 without any preoperative GERD symptoms. These patients were followed up for 1 year after the surgery. The incidence of post-OAGB GERD and BR was determined in all the patients using the GERD symptom questionnaire, GerdQ. RESULTS The mean age of the patients was 41.0 ± 11.6 years. A hernia was observed in 56 (29.2%) cases and GERD in 37 (19.3%). Hernia was small in 44 (22.9%) cases, medium in 11 (5.7%), and large in 1 (.5%). HH was found to be significantly correlated with GERD (P = .012). CONCLUSION The important post-OAGB complications, such as GERD and BR, have not been adequately addressed in literature. The present study found moderate and large HHs to be important factors for de novo GERD and repairing a HH during OAGB may be essential for preventing GERD-like symptoms.

Abstract
The single-anastomosis gastric bypass has been proposed as a simpler and efficient weight loss reducing surgery. Postoperative outcomes are comparable to those of contemporary popular procedures. There are, however, controversies regarding the efficiency and risks of one-anastomosis gastric bypass (OAGB). The purpose of this review is to define the role of OAGB in metabolic surgery via its operative outcomes. A review of English language literature was performed using the PubMed database, basing the search on the following keywords: “one-anastomosis gastric bypass” AND “outcomes”. A total of 238 articles were considered for review. Following thorough screening and selection criteria, 7 articles were considered sufficient for assessment. The nature of the available evidence of this technique poses a challenge to OAGB in its establishment as a standard of care procedure. The anatomical configuration following surgery, as well as the metabolic implications of its hypo-absorptive nature, raises controversial and ongoing concerns that are yet to be addressed. Hence, prospective studies with long-term follow-up (>5 years) can bypass these concerns and allow the progression of the clinical practice of OAGB.

Abstract
PURPOSE OF REVIEW Bariatric surgery and endoluminal bariatric therapies (EBTs) form an increasingly utilized therapeutic approach to treat obese patients but may worsen gastroesophageal reflux disease (GERD). In this updated article, we review the evidence on the effects of bariatric procedures on GERD. FINDINGS Recent evidence implicates sleeve gastrectomy with the highest rates of de novo GERD and Barrett's esophagus (BE), whereas malabsorptive-restrictive procedures such as Roux-en-Y gastric bypass (RYGB) and one anastomosis gastric bypass (OAGB) were shown to have significantly lower reported rates. The intragastric balloon (IGB) has been associated with increased likelihood of GERD, whereas insufficient evidence exists linking endoscopic sleeve gastroplasty (ESG) to GERD. SUMMARY Gastroesophageal reflux disease may be treated with some bariatric procedures but is often developed de novo as a result of the change in anatomy. Patients set to undergo bariatric surgery may benefit from pre-procedural endoscopy to choose the more suitable therapy. Further studies with objective measurements of GERD post procedure may provide more insight into the effects of bariatric therapies on reflux, especially more novel ones such as ESG.

Abstract
INTRODUCTION Bariatric surgery is increasingly performed. Since there are numerous surgical techniques, the effects of these on the esophageal function are still poorly understood. We aimed at assessing the effect of different techniques on esophagogastric junction (EGJ), esophageal peristalsis and reflux exposure using high-resolution manometry (HRM), and impedance-pH monitoring (MII-pH). METHODS All obese patients underwent symptomatic questionnaires, endoscopy, HRM, and MII-pH before and 1 year after surgery. Esophageal function and EGJ were classified according to Chicago Classification V. 3.0. Intragastric pressure (IGP) and gastroesophageal pressure gradient (GEPG) were assessed. Total acid exposure time (AET %), total number of refluxes, and symptom association probability (SAP) were assessed. A group of healthy volunteers (HVs) served as control. RESULTS One hundred and twelve obese subjects and 15 HVs (normal weight) were studied. Thirteen underwent endoscopic balloon placement (BIB), 12 gastric banding (GB), 26 sleeve gastrectomy (SG), 18 Roux-en-Y gastric bypass (RYGB), 15 mini-gastric bypass (MGB), 16 biliointestinal bypass (BIBP), and 12 biliopancreatic diversion (BPD). IGP and GEPG significantly decreased after RYGP, BPD, and BPBP, whereas they significantly increased after GB and SG. Post-operative greater AET (p < 0.05) and increased total number of reflux (p < 0.001) were present after GB and SG. RYGB and MGB showed a significant decrease in AET (p < 0.05) and total number of reflux (p < 0.001). CONCLUSIONS HRM verified that different bariatric techniques produced different modification of IGP and GEPG, leading to different reflux exposure. Only GB and SG can negatively impact on esophageal function and reflux exposure.

Abstract
BACKGROUND One anastomosis gastric bypass/mini-gastric bypass (OAGB/MGB) is considered an alternative option in metabolic and bariatric surgery. The aim of this study was to evaluate the safety, efficacy and postoperative challenges of OAGB/MGB as a new procedure. METHODS We performed 519 primary MGBs and 8 additional second-stage MGBs during 2014-2018. The data were collected from patients' notes as well as the surgeons' prospective data sheets. Two senior surgeons performed the operations. The ultimate primary measures were assessment of the safety and management of the complications. The secondary outcomes were excess weight loss and resolution of the comorbidities. RESULTS The type 2 diabetes mellitus (T2DM) remission rate was 83% and 70% over 1 and 3 years, respectively (HBA1C < 6.5%). Weight loss was 28-152 kg (SD 23.11). Excess weight loss ranged from 41 to 125%. Hypertension resolution was 61%, 58% and 58% in the first, second and third years, respectively. Ninety-nine per cent of sleep apnoea patients improved symptomatically and went off the continuous positive airway pressure (CPAP) machine. Two (0.37%) patients developed diarrhoea, cured by shortening the afferent biliopancreatic limb (BPL). Eight (1.5%) stomal ulcers were reported. Two patients (0.37%) developed deranged liver function, revised by shortening the BPL in one patient and a reversal in the second patient. The mean follow-up was 2.5 years. Mortality was zero. CONCLUSIONS This is the largest UK OAGB/MGB study to date showing safety and acceptable results for metabolic syndrome and obesity problems. OAGB/MGB revisional options are rectifying the morbidity and no mortality.

Abstract
BACKGROUND One anastomosis gastric bypass (OAGB) and sleeve gastrectomy (SG) are popular bariatric surgeries for morbid obesity. Reports on the safety and effectiveness of SG and OAGB are inconsistent. This meta-analysis investigated the clinical outcomes of SG versus those of OAGB for morbid obesity. METHODS Based on PRISMA guidelines, we searched the published articles in English from Scopus, PubMed (Medline), Central (Cochrane), and Embase databases. Articles were retrieved from the start date of each database to February 13, 2019. Statistical analysis of this meta-analysis was conducted in Stata 14.0, and the most appropriate effect model was chosen based on heterogeneity. RESULTS A total of 20 articles examining 4064 OAGB patients and 3733 SG patients were included in this meta-analysis. Compared with SG, OAGB showed a higher percentage excess weight loss (%EWL) at 6 months (weighted mean difference (WMD) = 11.32; 95% CI 6.00-16.64), 12 months (WMD = 8.22; 95% CI 3.78-12.66), 24 months (WMD = 10.19; 95% CI 0.88-21.25), 36 months (WMD = 7.93; 95% CI 3.37-12.48), 48 months (WMD = 17.22; 95% CI 7.37-27.06), and 60 months (WMD = 16.43; 95% CI 8.96-23.90). In addition, OAGB was associated with a lower rate of postoperative leak, gastroesophageal reflux disease, revisions, mortality, and dyslipidemia remission rates. However, OAGB increased the incidence of ulcers, malnutrition, and bile reflux. CONCLUSION OAGB is more effective for %EWL and dyslipidemia remission than SG. In addition, OAGB may lower the risk of postoperative leak, gastroesophageal reflux disease, revision, and mortality. Further comparisons of the clinical outcomes of OAGB versus SG for morbid obesity would benefit from more high-quality controlled studies.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) has been validated as a safe and effective treatment for morbid obesity. However, data of the long-term outcome remains lacking. METHODS A total of 1759 LSG was performed as primary bariatric procedure from 2005 to 2017 with mean age of 35.2 ± 10.3 years old (14-71), female 69.7%, mean body mass index (BMI) 37.9 ± 7.7 kg/m2, and mean waist width 113.7 ± 17.9 cm. All patients were evaluated and managed under a strict multidisciplinary team approach. A retrospective analysis of a prospective bariatric database and telephone interview of patients who defaulted clinic follow-up at 10 years was conducted. RESULTS The mean operating time, intraoperative blood, and hospital stay of LSG were 121.5 ± 36.5 min, 40.8 ± 69.7 ml, and 2.8 ± 2.7 days, respectively. The 30-day postoperative major complication occurred in 25 (1.4%) patients. The major complication rate was 15% at first year and 0% at the last year. The follow-up rate at 1, 5 and 10 years were 89.3%, 52.1 and 64.4%. At postoperative 1, 5, and 10 years, the mean percentage of total weight loss (%TWL) and excess weight loss (EWL%) of LSG patients were 33.4, 28.3, and 26.6% and 92.2, 80.1, and 70.5%, respectively. The mean BMI became 27, 26.2, and 27.1 kg/m2 at postoperative 1, 5, and 10 years. At follow-up, a total 69 patients needed surgical revision due to reflux disease (n = 45), weight regain (n = 19), persistent diabetes (n = 2), and chronic fistula (n = 3). The type of revision procedures were hiatal repair and gastropexy (n = 29), Roux-en Y gastric bypass (RYGB) (n = 23), and single anastomosis bypass (n = 17) with median time to revision 33 months (range 3-62). At 10 years, the overall revision rate was 21.5% (14/65) and 11(16.9%) of 65 patients were converted to RYGB. The other 54 patients remained at LSG anatomy, but 45% of them required proton pump inhibitor for reflux symptoms. CONCLUSIONS Our results showed that primary LSG is a durable primary bariatric procedure with sustained weight loss and a high resolution of comorbidities at 10 years, but about half the patients had de novo GERD. The need for conversion to RYGB was 16.9% at 10 years.

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.

Conversion from laparoscopic adjustable gastric banding (LAGB) and laparoscopic sleeve gastrectomy (LSG) to one anastomosis gastric bypass (OAGB): preliminary data from a multicenter retrospective study. Surg Obes Relat Dis 2019; 15:1332-1339. [PMID: 31272866 DOI: 10.1016/j.soard.2019.05.026] [Citation(s) in RCA: 35] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2019] [Revised: 04/19/2019] [Accepted: 05/19/2019] [Indexed: 12/12/2022]
Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is the most commonly performed bariatric procedure, while laparoscopic adjustable gastric banding (LAGB) has been for a decade one of the most popular interventions for weight loss. After LSG and LAGB, some patients may require a second surgery due to weight regain or late complications. One anastomosis gastric bypass (OAGB) is a promising bariatric procedure, which provides effective long-term weight loss and has a favorable effect on type 2 diabetes. OBJECTIVES To retrospectively analyze data from 10 Italian centers on conversion from LAGB and LSG to OAGB. SETTING High-volume centers for bariatric surgery. METHODS Prospectively collected data from 10 high-volume centers were retrospectively reviewed. Body mass index (BMI), percentage of excess BMI loss, reasons for redo, remission from co-morbidities (hypertension, diabetes, gastroesophageal reflux, and dyslipidemia), and major complications were recorded. RESULTS Three hundred patients were included in the study; 196 patients underwent conversion from LAGB to OAGB and 104 were converted from LSG. BMI was 45.1 ± 7 kg/m2 at the time of first intervention, 41.8 ± 6.3 kg/m2 at redo time, and 30.5 ± 5.5 kg/m2 at last follow-up appointment. Mean percentage of excess BMI loss was 13.2 ± 28.2 at conversion and 73.4 ± 27.5 after OAGB. Remission rates from hypertension, diabetes, gastroesophageal reflux, and dyslipidemia were 40%, 62.5%, 58.7% and 52%, respectively. Mean follow-up was 20.8 (range, 6-156) months and overall complications rate was 8.6%. CONCLUSION Our data show that OAGB is a safe and effective revisional procedure after failed restrictive bariatric surgery.

Abstract
The utilization of high-resolution manometry (HRM) has enhanced our understanding and assessment of esophageal motor disorders. Moreover, the combination of impedance technology with HRM (HRIM) has further improved our knowledge of esophageal physiology and the clinical evaluation of dysmotility, thanks to the addition of accurate measurement of bolus transit. Areas covered. This paper provides an overview of current knowledge in the use of HRIM for the study of esophageal functional disorders by reporting mainly the results of many publications and several systematic reviews in this field. Expert opinion. HRIM has represented a relevant improvement in the assessment of esophageal motility and has required the development of new metrics, such as the esophageal impedance integral ratio, the bolus flow time, the nadir impedance pressure and the impedance bolus height, which increase the evaluation of esophageal bolus transit. An extension of impedance is represented by functional lumen imaging probe (FLIP), which determines the biophysical properties and the distensibility of the esophagus and permits to detect contractility patterns not seen on HRM alone. We eagerly wait for a new and fruitful iteration of the Chicago Classification, now in version 3.0, which can cover the ongoing clinical experience of HRIM.
