Endoscopic Sleeve Gastroplasty (ESG)

Long-Term Follow up and Outcomes After ESG for Treatment of Obesity (5 Year Data). Authors: Kaveh Hajifathalian, Bryan Ang, Qais Maher Dawod, Shawn Laxmikant Shah, Enad Dawod, Amit Mehta, Saurabh Mukewar, SriHari Mahadev, Kartik Sampath, David L. Carr-Locke, Danny Issa, Louis J. Aronne, Rekha Kumar, Alpana Shukla, Reem Z. Sharaiha. Cornell, NYC, New York, United States.

This abstract included the first 5-year patient data on the ESG procedure. Of those patients who had reached the 5 year follow-up mark, 69% of patients remained at least 10% below their initial total body weight with an average total body weight loss (“TBWL”) of 14.5%.

Endoscopic Sleeve Gastroplasty: A Meta-Analysis of Weight Loss Outcomes. Authors: Edward Villa, Christopher Grant Chapman. Center for Endoscopic Research and Therapeutics, University of Chicago, Chicago, Illinois, United States.

This meta-analysis evaluated the effectiveness of ESG in terms of TBWL, excess body weight loss (“EBWL”), and body mass index (“BMI”). Five studies with 550 patients showed pooled 6-month TBWL of 15.6% and five studies with 365 patients were used for pooled 12-month TBWL of 17.0%. For EBWL, six studies with 337 patients were used for pooled 6-month EBWL of 56.3% and four studies with 223 patients were used for pooled 12-month EBWL of 67.8%. Finally, five studies with 301 patients were used to derive pooled 6-month BMI decrease of 13.1% and five studies with 332 patients for pooled 12-month BMI decrease of 14.5%.

Evaluation of Weight Loss and Adverse Events Associated with ESG: A Pooled Analysis with Systematic Review. Authors: Zohair Ahmed1, Najib Nassani1, Jean M. Chalhoub2, Brian R. Boulay.11 Gastroenterology and Hepatology, University of Illinois at Chicago, Chicago, Illinois, United States; 2 Gastroenterology and Hepatology, University of Massachusetts Medical Center, Springfield, Massachusetts, United States.


The pooled analysis included eleven studies (prospective and retrospective) of ESG published between January 2013 and October 2018 and included 477 patients. The pooled TBWL was 16.5% at 6 months. The review identified no serious adverse events or patient mortality.

ESG for Obesity: Improved Body Composition at 1-Year Follow-Up. Authors Adrian Sartoretto2, George Marinos2, Zhixian Sui.1,21 The University of New South Wales, Randwick, New South Wales, Australia,  2 The BMI Clinic, Double Bay, New South Wales, Australia.

This study analyzed 121 consecutive patients who underwent ESG in an outpatient setting from October 2016 to January 2018. At one year, the average TBWL was 17% and 80% of patients had lost more than 10%. Unique to this study was the evaluation of body composition. On average, there was a reduction in body fat mass of 15.7 kg, and an increase in lean body mass of 3.5 kg, and a reduction in visceral fat mass of 1.4 kg. The authors suggested that the increase in lean body mass and improved body composition lowers the risk of weight regain following an ESG. The authors also reported that there were no major intra or post procedure complications.

Safety and Efficacy of ESG for Obesity Management in New Bariatric Endoscopy Programs: A Multicenter International Study. Authors:  Avik Sarkar1, Augustine Tawadros1, Iman Andalib1, Haroon M. Shahid1, Amy Tyberg1, Resheed Alkhiari1, Monica Gaidhane1, Prashant Kedia2, Keshav Kukreja2, Elizabeth S. John2, Bryce Bushe2, Ma Guadalupe Martínez4, Felipe Zamarripa4, Mine C. Carames5, Juan C. Carames5, Fernando Casasrodriguez6, Vincenzo Bove3, Guido Costamagna3, Ivo Boskoski3, Michel Kahaleh.11 Gastroenterology, Robert Wood Johnson, New Brunswick, New Jersey, United States; 2 Gastroenterology, Methodist Hospital, Dallas, Texas, United States;  3 Gastroenterology, Fondazione Policlinico A. Gemelli, Roma, Italy;  4 Gastroenterology, Hospital Juarez de Mexico, Mexico City, Mexico; 5 Gastroenterology, Santander Hospital, Reynosa, Mexico;  6 Gastroenterology, Hospital Central de la Policia, Bogota, Colombia.

This was an international, multicenter, retrospective study reviewing the outcomes of ESG in centers starting an ESG program. The study reported technical success in 100% of the patients in all six centers, a mean procedure time of 89 minutes, and no significant adverse events. These results demonstrated equivalence in outcomes for new ESG centers as compared to previous studies by experienced ESG centers.

Bariatric Surgery Revisions

Endoscopic Suturing for Weight Regain After Sleeve Gastrectomy: Mulitcenter Series. Authors: Eric J. Vargas1, Jose Nieto2, Andrew C. Storm1, Lea Fayad3, Fateh Bazerbachi1, Reem Matar1, Vivek Kumbhari3, Barham K. Abu Dayyeh.11 Gastroenterology and Hepatology, Mayo Clinic , Rochester, Minnesota, United States;  2 Borland Groover Clinic, Jacksonville, Florida, United States; 3 Johns Hopkins Medicine, Baltimore, Maryland, United States.

Weight regain is a common occurrence following sleeve gastrectomy weight loss surgery. This was a multicenter retrospective cohort study that reported on the use of endoscopic suturing to address patient weight regain following sleeve gastrectomy. Mean percentage TBWL at 1, 2, 3, 6, and 9 months was 5.8%, 9.9%, 10.2%, 12.7%, and 18.5%, respectively following the revision. The study showed that using OverStitch for revision of sleeve gastrectomy after weight regain was safe and an effective treatment as an adjunct to lifestyle and pharmacotherapy.

Comparison of Endoscopic and Surgical Revisions in the Treatment of Weight Regain Following Roux-en Y Gastric Bypass. Authors: Pichamol Jirapinyo, Ethan Dwane Maahs, Christopher C. Thompson. Brigham & Women’s Hospital, Boston Massachusetts, United States.

Weight regain is a common occurrence following Roux-en Y gastric bypass (“RYGB”) surgery. Revision options for these patients include Transoral outlet reduction (“TORe”), an endoscopic procedure that uses endoscopic suturing, and surgical RYGB revision. The authors conducted a matched cohort study of patients who underwent either endoscopic or surgical revision of RYGB for treatment of weight regain. At six months the endoscopic and surgical groups had lost on average 11.2% and 10.3%, respectively, of their total body weight and at twelve months the endoscopic and surgical groups had lost on average 13.9% and 12.6% of their total body weight. The rates of serious adverse events were 5.6% and 38.9% for the endoscopic and surgical groups, respectively. Endoscopic revision using suturing offered greater safety and comparable weight loss to surgical revision.

Non-bariatric intervention

Determining Appropriate Reimbursement for Innovative Endoscopic Devices Using Cost-Minimization Analysis: Endoscopic Suturing to Prevent Stent Migration for Benign Esophageal Strictures. Authors: Eric Dinesh Shah1, Amy E. Hosmer2, Arpan H. Patel3, Shannon Morales1, Ryan Law.31 Gastroenterology, Dartmouth-Hitchcock Medical Center, Lebanon, New Hampshire, United States; 2 The Ohio State University, Columbus, Ohio, United States;  3 Division of Gastroenterology, Michigan Medicine, Ann Arbor, Michigan, United States .

The authors developed a decision analytic model comparing fully-covered metal stent placement with or without stent anchoring using an endoscopic suturing device for non-malignant conditions (fistula, leak, perforation or stricture) from a payer perspective. The model accounted for technical success rates of suture placement, clinically significant adverse events with suturing and stent migration rates with or without endoscopic suturing based on a recent systematic review. The authors concluded that a defined reimbursement pathway for endoscopic suturing is justified to prevent stent migration.

Endoscopic Rectal Reconstruction After Removal of Large Rectal Lesions. Authors: Sergey V. Kantsevoy, Shira Levihim, Alan Chen, Amit Raina, Paul J. Thuluvath. Mercy Medical Center, Baltimore, Maryland, United States.

The study evaluated the technical feasibility and effectiveness of endoscopic reconstruction of rectal mucosa using the OverStitch endoscopic suturing system to prevent immediate and delayed adverse events after the en bloc endoscopic removal of large rectal lesions. Reconstruction of the rectal mucosa in all patients was successful and all patients were discharged home with rectal reconstruction and none of the study patients had either immediate or delayed adverse events. The study concluded that endoscopic rectal reconstruction was effective in preventing immediate and delayed adverse events after the endoscopic removal of large rectal lesions.
