Abstract
OBJECTIVE To study esophageal acid exposure, esophageal motility, and endoscopic findings before and after Sleeve Gastrectomy (SG) and Roux-en-Y Gastric Bypass (RYGB BACKGROUND: The lack of standardized objective assessment of esophageal physiology and anatomy contributes to the controversies regarding the impact of SG and RYGB on gastroesophageal reflux disease. METHODS We conducted a systematic review and meta-analysis of studies reporting at least one objective measure of esophageal physiology and/or EGD, at baseline and after SG or RYGB. The changes in pH-test, manometry, and EGD parameters were summarized. RESULTS Acid exposure time (AET) and DeMeester Score (DMS) significantly increased after SG: Mean Difference (MD) 2.1 (95%CI 0.3 to 3.9) and 8.6 (95%CI 2 to 15.2), respectively. After RYGB, both AET and DMS significantly decreased: MD -4.2 (95%CI -6.1 to -2.3) and - 16.6 (95%CI -25.4 to -7.8). Lower esophageal sphincter resting pressure and length significantly decreased following SG: MD - 2.8 (95%CI - 4.6 to - 1.1) and - 0.1 (95%CI - 0.2 to - 0.02), respectively. There were no significant changes in esophageal manometry after RYGB. The Relative Risk of erosive esophagitis after SG was 2.3 (95%CI 1.5 to 3.5), while after RYGB it was 0.4 (95%CI 0.2 - 0.8). The prevalence of Barrett's Esophagus changed from 0% to 3.6% after SG, and from 2.7% to 1.4% after RYGB. CONCLUSIONS SG resulted in worsening of all objective parameters, while RYGB showed improvement in AET, DMS, and EGD findings. Determining the risk factors associated with those outcomes could aid in surgical choice.

Abstract
Sleeve gastrectomy (SG) is the most performed bariatric surgery worldwide. However, this surgery may be associated with long-term weight regain and severe gastroesophageal reflux disease (GERD), sometimes necessitating conversion to Roux-en-Y gastric bypass (RYGB) to improve quality of life (QoL). We conducted a systematic review on QoL measures following the conversion of SG to RYGB. We searched various databases for studies conducted between January 2005 and September 2023. Four studies, involving 196 participants in total, met the inclusion criteria. Different assessment methods were used to evaluate QoL following the conversion. In the included studies, we observed that GERD symptoms and proton pump inhibitor (PPI) use both decreased following conversion to RYGB. Excess weight loss (EWL) was also observed in all studies.

Long-term impact of gastropexy on use of acid-reducing medication, second operations for gastroesophageal reflux and subjective reflux symptoms after sleeve gastrectomy. Clin Obes 2023; 13:e12618. [PMID: 37583310 DOI: 10.1111/cob.12618] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Revised: 07/20/2023] [Accepted: 07/26/2023] [Indexed: 08/17/2023]
Abstract
We investigated whether adding gastropexy to sleeve gastrectomy (SG) reduced gastroesophageal reflux disease (GERD) in patients operated for severe obesity, assessed mainly by use of anti-reflux medication (ARM) and second operations due to GERD worsening. In a prospective non-randomized study, patients undergoing SG at two Norwegian hospitals were included from 2011 to 2015 and followed for 7 years. GERD was defined by regular use of ARM, and epigastric pain and heartburn were measured by the Rome II questionnaire. Gastropexy was done by suturing the gastrocolic ligament to the staple line. Patients undergoing SG only, mainly before gastropexia was introduced in 2013, were compared to those with additional gastropexy from 2013 onwards. Of 376 included patients (75% females, mean age 42.6 years and BMI 42.9 kg/m2 ), 350 (93%) and 232 (62%) were available for evaluation after 1 and 7 years, respectively. Baseline characteristics in the no-gastropexy (n = 235) and gastropexy groups (n = 141) were similar. In patients without ARM use before surgery, the use increased and in those that used ARM at baseline, the proportion decreased, with no difference in the no-gastropexy and gastropexy groups. With a combined endpoint of ARM use and/or second operation for GERD, there was no difference during follow-up between the two groups. With time, adding gastropexy did not reduce symptoms of GERD significantly. In this population, adding gastropexy to SG did not reduce use of ARM and/or second operation for uncontrolled GERD, epigastric pain or heartburn during the first 7 postoperative years.

Abstract
LSG is one of the most performed bariatric procedures worldwide. It is a safe and effective operation with a low complication rate. Unsatisfactory weight loss/regain may occur, suggesting that the operation design could be improved. A bioengineering approach might significantly help in avoiding the most common complications. Computational models of the sleeved stomach after LSG were developed according to bougie size (range 27-54 Fr). The endoluminal pressure and the basal volume were computed at different intragastric pressures. At an inner pressure of 22.5 mmHg, the basal volume of the 54 Fr configuration was approximately 6 times greater than that of the 27 Fr configuration (57.92 ml vs 9.70 ml). Moreover, the elongation distribution of the gastric wall was assessed to quantify the effect on mechanoreceptors impacting satiety by differencing regions and layers. An increasing trend in elongation strain with increasing bougie size was observed in all cases. The most stressed region and layer were the antrum (approximately 25% higher stress than that in the corpus at 37.5 mmHg) and mucosa layer (approximately 7% higher stress than that in the muscularis layer at 22.5 mmHg), respectively. In addition, the pressure-volume behaviors were reported. Computational models and bioengineering methods can help to quantitatively identify some critical aspects of the "design" of bariatric operations to plan interventions, and predict and increase the success rate. Moreover, computational tools can support the development of innovative bariatric procedures, potentially skipping invasive approaches.

ASMBS position statement on the rationale for performance of upper gastrointestinal endoscopy before and after metabolic and bariatric surgery. Surg Obes Relat Dis 2021; 17:837-847. [PMID: 33875361 DOI: 10.1016/j.soard.2021.03.007] [Citation(s) in RCA: 47] [Impact Index Per Article: 15.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2021] [Accepted: 03/13/2021] [Indexed: 12/18/2022]
Abstract
The following position statement is issued by the American Society for Metabolic and Bariatric Surgery in response to inquiries made to the Society by patients, physicians, society members, hospitals, health insurance payors, the media, and others regarding the need and possible strategies for screening endoscopic examination before metabolic and bariatric surgery (MBS), as well as the rationale, indications, and strategies for postoperative surveillance for mucosal abnormalities, including gastroesophageal reflux disease and associated esophageal mucosal injuries (erosive esophagitis and Barrett's esophagus) that may develop in the long term after MBS, specifically for patients undergoing sleeve gastrectomy or Roux-en-Y gastric bypass. The general principles described here may also apply to procedures such as biliopancreatic diversion (BPD) and BPD with duodenal switch (DS); however, the paucity of procedure-specific literature for BPD and DS limits the value of this statement to those procedures. In addition, children with obesity undergoing MBS may have unique considerations and are not specifically addressed in this position statement. This recommendation is based on current clinical knowledge, expert opinion, and published peer-reviewed scientific evidence available at this time. The statement is not intended to be and should not be construed as stating or establishing a local, regional, or national standard of care. The statement will be revised in the future as additional evidence becomes available.
