The impact of suture material on stricture rate when performing a hand-sewn GJA is not well established. Methods: This is a retrospective analysis of a prospectively maintained database that includes 882 patients who underwent primary or revisional LRYGB with a minimum 12-month follow-up. We compared two consecutive groups of patients who underwent hand-sewn gastrojejunal anastomosis: group 1 (n = 426), utilizing a multifilament non-absorbable\/absorbable suture combination (silk\/Vicryl\u00ae), whereas group 2 (n = 456) received an absorbable monofilament suture (Monocryl\u00ae). The primary outcome was the incidence of symptomatic GJA stricture, defined as an inability to pass a 10 mm gastroscope associated with dysphagia, vomiting, or food intolerance. Results: The symptomatic stricture rate was significantly lower in group 2 (0.7% vs. 6.8%; p &lt; 0.001). On multivariate analysis, the use of monofilament sutures was a stronger protective factor (OR 0.09; 95% CI 0.03\u20130.30; p &lt; 0.001), whereas revisional surgery was associated with an increased risk of symptomatic stricture (OR 2.61; 95% CI 1.05\u20136.50; p = 0.03). Type 2 diabetes mellitus and gender were not independent predictors. One-year weight loss was similar between patients who developed symptomatic strictures (and required dilations) and those who did not (p &gt; 0.05). Conclusion: The use of absorbable monofilament sutures for hand-sewn GJA in LRYGB reduces the risk of symptomatic stricture without compromising weight loss outcomes. These findings support a personalized suture strategy, especially in high-risk patients undergoing revisional surgery.<\/jats:p>","DOI":"10.3390\/jpm16080431","type":"journal-article","created":{"date-parts":[[2026,8,17]],"date-time":"2026-08-17T11:00:05Z","timestamp":1786964405000},"page":"431","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Hand-Sewn Gastrojejunal Anastomosis in Laparoscopic Roux-en-Y Gastric Bypass: A Comparison of Absorbable Monofilament Versus Non-Absorbable Multifilament Sutures and Their Impact on the Symptomatic Anastomotic Stricture Rate"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4807-985X","authenticated-orcid":false,"given":"Hugo A.","family":"Sanchez","sequence":"first","affiliation":[{"name":"The Nutrition & Obesity Clinic, ABC Medical Center, Sur 136 # 116, M\u00e9xico City 01120, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guillermo","family":"Ponce de Leon-Ballesteros","sequence":"additional","affiliation":[{"name":"Department of Surgery, Hospital Angeles Morelia, Morelia 58350,  Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miguel F.","family":"Herrera","sequence":"additional","affiliation":[{"name":"The Nutrition & Obesity Clinic, ABC Medical Center, Sur 136 # 116, M\u00e9xico City 01120, Mexico"},{"name":"Department of Surgery, Instituto Nacional de Ciencias M\u00e9dicas y Nutrici\u00f3n Salvador Zubir\u00e1n, Vasco de Quiroga 15, M\u00e9xico City 14000, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"309","DOI":"10.1007\/s11695-019-04032-x","article-title":"Bariatric Metabolic Surgery Standardization (BMSS) Working Group: Standardization of Bariatric Metabolic Procedures: World Consensus Meeting Statement","volume":"29","author":"Bhandari","year":"2019","journal-title":"Obes.
