Abstract
BackgroundRoux-en-Y gastric bypass (RYGBP) and laparoscopic sleeve gastrectomy (LSG) are efficient methods for weight loss (WL) and WL maintenance in severe obesity. However, the knowledge of gastrointestinal (GI) symptoms after surgery is limited. This study aimed to compare the severity of GI symptoms, pain, and self-rated health 2 to 4 years after RYGBP and LSG surgery.MethodsIn this cross-sectional study, RYGBP and LSG patients answered a questionnaire including the Gastrointestinal Symptom Rating Scale (GSRS), questions from the Brief Pain Inventory (BPI), and self-rated health (SRH).ResultsA total of 172/303 (57%) responded, RYGBP (n=73) and LSG (n=99). The mean age was 45.3 (SD 11.1) years (74% females). There was no evidence of a difference in total GSRS scores between the surgical methods (p=0.638). There were higher scores of reflux symptoms in LSG vs. RYGBP (both median 1, 75-percentile 2.5 vs. 1.0, p <0.001) and higher consumption of acid-reducing medication after LSG (32% vs. 12%, p <0.001). Pain scores were low in both groups; however, average abdominal pain was higher for RYGBP, median 2 (IQR 0–4) vs. median 1 (IQR 0–3) for LSG (p = 0.025). There was no significant difference in SRH.ConclusionsPatients undergoing RYGBP and LSG surgery reported similar total GSRS scores and low pain scores 2 to 4 years after surgery. However, reflux symptoms and use of acid-reducing medication occurred more frequently after LSG surgery, while abdominal pain was more frequent in RYGBP surgery. These findings are important for surgical decision-making and follow-up.Graphical abstract
Highlights
Roux-en-Y gastric bypass (RYGBP) and laparoscopic sleeve gastrectomy (LSG) are the most common bariatric surgeries worldwide [1]
A multiple linear regression was used to study the association between the natural logarithm of total Gastrointestinal Symptom Rating Scale (GSRS) score and the explanatory variables surgical method, gender, age, % total weight loss (TWL), smoking habits, and time after surgery
This study showed no significant difference in the occurrence of self-reported GI symptoms measured with total GSRS between participants undergone RYGBP and LSG 2 to 4 years after surgery
Summary
Roux-en-Y gastric bypass (RYGBP) and laparoscopic sleeve gastrectomy (LSG) are the most common bariatric surgeries worldwide [1] Both procedures are efficient for weight loss (WL) and WL maintenance and for remission of comorbidities such as type 2 diabetes mellitus (T2DM) and cardiovascular diseases [2]. Abdominal pain after RYGBP is more common in younger women and associated with lower education levels, smoking, and total bodily pain [10, 17] Both RYGBP and LSG impose physiological and anatomical alterations that may cause GI symptoms, but GI symptoms may be related to a variety of physical and psychological conditions. This study aimed to compare the severity of GI symptoms, pain, and self-rated health 2 to 4 years after RYGBP and LSG surgery. Methods In this cross-sectional study, RYGBP and LSG patients answered a questionnaire including the Gastrointestinal Symptom Rating Scale (GSRS), questions from the Brief Pain Inventory (BPI), and self-rated health (SRH).
