Abstract
LAPENA RODRIGUEZ, María et al. Clinical symptoms are correlated with gastrojejunal anastomosis complications only during the first year after laparoscopic Roux-en-Y gastric bypass. Nutr. Hosp. [online]. 2021, vol.38, n.5, pp.978-982. Epub Jan 24, 2022. ISSN 1699-5198. https://dx.doi.org/10.20960/nh.03602.
Introduction:
after laparoscopic Roux-en-Y gastric bypass (LRYGBP) many patients complain of epigastric pain or food intolerance, leading to the performance of upper gastrointestinal (UGI) endoscopy.
Objective:
this study aims to assess which symptomatology as reported by LRYGBP patients during follow-up suggested correlation with pathological findings of endoscopy, and which factors might play a role, taking the timing of symptom presentation into account.
Materials and methods:
a retrospective cohort study was performed identifying LRYGBP patients presenting with food intolerance and/or epigastric pain who had undergone endoscopy. Primary outcomes were endoscopy findings, their association with patient characteristics, and timing of symptom presentation.
Results:
of the 514 patients complaining of epigastric pain and/or food intolerance, 81 (15.6 %) underwent endoscopy. A gastrojejunostomy complication was found in 58 % of cases. All patients who complained about food intolerance and epigastric pain presented pathological findings. The only preoperative factor associated with a gastrojejunostomy complication was being a smoker (p = 0.021). Time between surgery and endoscopy was also a predictive factor for endoscopic pathological findings (p = 0.007); in cases of epigastric pain, symptom onset during the first year (median: 10 months) was related to increased risk of gastrojejunal complications (p < 0.05).
Conclusions:
endoscopies performed within one year of surgery were significantly more likely to reveal pathological findings than endoscopies performed after the first postoperative year, especially in patients experiencing epigastric pain.
