Gastroesophageal Symtomps after laparoscopic gastric bypass: mistakes in performing the procedure?
Author
Abstract
Laparoscopic Roux-en-Y gastric bypass (LGB) is the recommended procedure for morbidly obese patients with gastroesophageal reflux disease (GERD). However, there have been reported gastroesophageal reflux symptoms or esophagitis after LGB. Few functional esophageal studies have been reported to date. AIM: To evaluate the anatomic and physiologic factors contributing to the appearance of these problems in patients who underwent LGB. METHODS: This prospective study included 38 patients with postoperative gastroesophageal reflux symptoms submitted to LGB. They were subjected to clinical, endoscopic, radiologic, manometric, and 24-h pH-monitoring evaluations. RESULTS: Eighteen (47.4%) of 38 patients presented with heartburn or regurgitation, 7 presented with pain, and 4 presented with dysphagia. Erosive esophagitis was observed in 11 (28.9%) patients, and Barrett's esophagus (5.7%) and jejunitis (10.5%) were also observed. Hiatal hernia was the most frequent finding observed in 15 (39.5%) patients, and most (10.5%) of these patients appeared with concomitant anastomotic strictures. A long blind jejunal loop was detected in one (2.6%) patient. Nearly 75% of the patients had hypotensive lower esophageal sphincter (9.61 +/- 4.05 mmHg), 17.4% had hypomotility of the esophageal body, and 64.7% had pathologic acid reflux (% time pH <4=6.98 +/- 5.5; DeMeester's score=32.4 +/- 21.15). CONCLUSION: Although rare, it is possible to observe gastroesophageal reflux and other important postoperative symptoms after LGB, which are associated with anatomic and physiologic abnormalities at the esophagogastric junction and proximal gastric pouch. O bypass gástrico laparoscópico em Y de Roux (BGL) é o procedimento de escolha para pacientes com obesidade mórbida com doença do refluxo gastroesofágico (DRGE). No entanto, foram relatados sintomas de refluxo gastroesofágico ou esofagite após BGL. Poucos estudos esofágicos funcionais foram relatados até o momento. OBJETIVO: Avaliar os fatores anatômicos e fisiológicos que contribuem para o surgimento desses problemas em pacientes submetidos a BGL. MÉTODOS: Este estudo prospectivo incluiu 38 pacientes submetidos a BGL apresentando sintomas de refluxo gastroesofágico pós-operatório. Eles foram submetidos a avaliações clínicas, endoscópicas, radiológicas, manométricas e de pHmetria de 24 horas. RESULTADOS: 18/38 (47,4%) dos pacientes apresentavam azia ou regurgitação, 7 apresentavam dor e 4 pacientes apresentavam disfagia. Esofagite erosiva observada em 11 pacientes (28,9%), esôfago de Barrett (5,7%) e jejunite (10,5%) também foram observadas. A hérnia de hiato foi o achado mais frequente observado em 15 pacientes (39,5%), a maioria deles com estenoses anastomóticas concomitantes (10,5%). Alça jejunal cega longa foi detectada em 1 paciente (2,6%). Quase 75% dos pacientes apresentavam esfíncter esofágico inferior hipotensivo (9,61- + 4,05 mmHg), 17,4% tinham hipomotilidade do corpo esofágico e 64,7% apresentavam refluxo ácido patológico (% tempo pH <4 = 6,98- + 5,5; pontuação de DeMeester = 32,4- + 21,15). CONCLUSÃO: Embora raros, é possível observar refluxo gastroesofágico e outros sintomas pós-operatórios importantes após BGL, os quais estão associados a alterações anatômicas e fisiológicas na junção esofagogástrica e bolsa gástrica proximal.
