BRAVO-TORREBLANCA, Carlos et al. Correlation of pre and postoperative endoscopic findings in patients subjected to bariatric surgery. Cir. gen [online]. 2013, vol.35, n.1, pp.20-24. ISSN 1405-0099.

Objective: To establish a correlation between the pre-operative endoscopic findings with the gastrointestinal syndrome and endoscopic findings during follow-up of patients subjected to bariatric surgery. Setting: General Hospital ''Dr. Manuel Gea González'' (third level health care center). Design: A retrospective, descriptive, cross-sectional, comparative study. Statistical analysis: Percentages as summary measures for qualitative variables and χ². Patients and method: Patients operated in the obesity clinic from June 2006 to June 2010, in whom a preoperative endoscopy was performed with a follow-up of at least 1 years. We identified the gastrointestinal pathologies with the highest incidence, histopathological findings, and the correlation with the postoperative endoscopy during the follow-up of patients, who, due to their symptoms, required endoscopic control. Results: In a total of 137 patients that complied with the inclusion criteria (111 women and 26 men), average age of 36.41 years, average BMI of 42.04, the pathology with the highest incidence was non-specific non-erosive gastritis (45.25%), the most frequent histopathological result was gastritis associated to Helicobacter pylori (HP) (38.6%). At an average follow-up of three years (SD ± 1.31), 35 patients (25.5%) were subjected to follow-up endoscopy due to gastrointestinal symptoms. Endoscopic findings were: non-specific, non-erosive gastritis (54.28%), without alterations (31.42%), and stenosis of the anastomoses (14.7%). Conclusion: Preoperative endoscopy is very useful as it allows identifying pathologies that can be associated to other complications and taking the necessary measures to prevent them.
