- Long-term follow-up after transoral outlet reduction following Roux-en-Y gastric bypass: Back to stage 0?(2023) BRUNALDI, Vitor Ottoboni; OLIVEIRA, Guilherme Henrique Peixoto de; KERBAGE, Anthony; RIBAS, Pedro Henrique; NUNES, Felipe; FARIA, Galileu; MOURA, Diogo de; RICCIOPPO, Daniel; SANTO, Marco; MOURA, Eduardo deBackground and study aims Significant weight regain affects up to one-third of patients after Roux-en-Y gastric bypass (RYGB) and demands treatment. Transoral outlet reduction (TORe) with argon plasma coagulation (APC) alone or APC plus full-thickness suturing TORe (APC-FTS) is effective in the short term. However, no study has investigated the course of gastrojejunostomy (GJ) or quality of life (QOL) data after the first post-procedure year.Patients and methods Patients eligible for a 36-month follow-up visit after TORe underwent upper gastrointestinal endoscopy with measurement of the GJ and answered QOL questionnaires (RAND-36). The primary aim was to evaluate the long-term outcomes of TORe, including weight loss, QOL, and GJ anastomosis (GJA) size. Comparisons between APC and APC-FTS TORe were a secondary aim.Results Among 39 eligible patients, 29 returned for the 3-year follow-up visit. There were no significant differences in demographics between APC and APC-FTS TORe groups. At 3 years, patients from both groups regained all the weight lost at 12 months, and the GJ diameter was similar to the pre-procedure assessment. As to QOL, most improvements seen at 12 months were lost at 3 years, returning to pre-procedure levels. Only the energy/fatigue domain improvement was kept between the 1- and 3-year visits.Conclusions Obesity is a chronic relapsing disease. Most effects of TORe are lost at 3 years, and redilation of the GJA occurs. Therefore, TORe should be considered iterative rather than a one-off procedure.
- FULL-THICKNESS ENDOSCOPIC SUTURING PLUS APC VERSUS APC ALONE TO TREAT WEIGHT REGAIN FOLLOWING ROUX-EN-Y GASTRIC BYPASS: AN INTERIM ANALYSIS OF A RANDOMIZED CONTROLLED TRIAL(2019) BRUNALDI, Vitor O.; FARIAS, Galileu F.; REZENDE, Daniel T.; NUNES, Gabriel C.; MOURA, Diogo T. de; NETO, Manoel Galvao; SOUZA, Thiago F.; RICCIOPPO, Daniel; SANTO, Marco Aurelio; MOURA, Eduardo G. de
- Small-Volume, Fast-Emptying Gastric Pouch Leads to Better Long-Term Weight Loss and Food Tolerance After Roux-en-Y Gastric Bypass(2018) RICCIOPPO, Daniel; SANTO, Marco Aurelio; ROCHA, Manoel; BUCHPIGUEL, Carlos Alberto; DINIZ, Marcio Augusto; PAJECKI, Denis; CLEVA, Roberto de; KAWAMOTO, FlavioAnatomical and functional influences on gastric bypass (GBP) results are often poorly evaluated and not yet fully understood. The purpose of this study is to evaluate the influence of the gastric pouch volume and its emptying rate on long-term weight loss and food tolerance after GBP. Weight loss, food tolerance, pouch volumetry (V) by three-dimensional reconstruction, and pouch emptying rate by 4 h scintigraphy were evaluated in 67 patients. Cutoffs were identified for V and retention percentage (%Ret) at 1 h (%Ret1). From these parameters, the sample was categorized, looking for associations between V, %Ret, weight loss, and food tolerance, assessed by a questionnaire for quick assessment of food tolerance (SS). PO median follow-up time was 47 months; median V was 28 mL; %Ret at 1, 2, and 4 h were 8, 2, and 1%, respectively. There were associations between V <= 40 mL and higher emptying rates up to 2 h (V <= 40 mL: %Ret1 = 6, %Ret2 = 2, p = 0.009; V > 40 mL: %Ret1 = 44, %Ret2 = 13.5, p = 0.045). An association was found between higher emptying speed in 1 h and higher late weight loss (WL), represented by lower percentage of excess weight loss (%EWL) regain (p = 0.036) and higher %EWL (p = 0.033) in the group with %Ret1 <= 12%, compared to the group %Ret1 >= 25%. Better food tolerance (SS > 24), was associated with lower %Ret1 (p = 0.003). Smaller pouch size is associated with a faster gastric emptying, greater WL maintenance, and better food tolerance. These data suggest that a small pouch with rapid emptying rate is an important technical parameter for good outcomes in GBP.
