- Open Roux-en-Y gastric bypass (RYGB) may be chosen because of known widespread adhesions or as a result of conversion during laparoscopic surgery. Although conversions are rare, they occur even in experienced hands. The gastrojejunostomy may be performed with a circular stapler (CS) or a linear stapler (LS) or may be entirely hand sewn (HS). Our aim was to study differences in outcomes regarding the anastomotic techniques utilized in open surgery.
- Laparoscopic Roux-en-Y gastric bypass (LRYGB) is a popular bariatric procedure associated to potential risk of late complications like anastomotic marginal ulceration, stricture, fistula formation, weight gain, and nutritional deficiencies [1–6].
- The incidence of marginal ulceration after gastric bypass has been reported with significant variability (1–16%) . Although its pathogenesis is unclear, several factors are associated with ulcer formation, including acid exposure, ischemia, foreign body, medications, and tobacco. In general, pharmacologic therapy is highly effective for ulcer healing, and surgical intervention is usually reserved for complications—typically bleeding or perforation. Rarely, surgical intervention is indicated for cases refractory to medical therapy.
- Laparoscopic Roux-en-Y gastric bypass as a treatment of severe obesity has increased dramatically in the past decade, and most of the patients have been women [1,2]. The health risks experienced by obese women during pregnancy can be reduced by the weight loss induced by bariatric surgery [3–5], but these patients are at risk of bariatric surgical complications during their pregnancies. Women who have undergone Roux-en-Y gastric bypass for morbid obesity are at risk of internal hernias, intussusception, and small bowel obstruction during pregnancy, which can lead to maternal and/or fetal death .
