Suter et al. 2007, Switzerland |
300 patients after BG, 600 after RYGB, 75 non-obese and 55 non-operated obese |
Prospective |
Develop a questionnaire to assess food tolerance in the postoperative follow-up |
Quarterly during the 1st year after surgery, every two years from 2 to 5 years after surgery and annually thereafter |
Patients after RYGB had better food tolerance over time compared to BG; the questionnaire is reliable, easy to use and comfortable to the patient |
Schweiger et al., 2010, Israel |
218 patients (99 after RYGB, laparoscopic adjustable BG 49 after, 56 after GV and 14 after biliopancreatic diversion with duodenal switch) |
Prospective |
Evaluate food intolerance and food quality compared to surgical technique and postoperative time |
Patients divided into 3 groups according to postoperative: 3-6 months, 6-12 months and longer than 12 months; questionnaire administered once in each group |
Patients after laparoscopic adjustable BG had lower quality on food compared to other techniques evaluated by the study |
D'Hont et al., 2011, Belgium |
83 patients after laparoscopic GV and 83 non-obese |
Retrospective |
Compare the group undergoing laparoscopic GV with the non-obese |
Postoperatively GV laparoscopic and is not specified at what time |
The tolerance was significantly higher in non-obese patients |
Keren et al., 2011, Israel |
119 patients after laparoscopic GV, 83 regularly followed postoperatively and 36 irregularly |
Retrospective |
Compare the two post-surgical groups GV laparoscopic |
In both groups to complete 30 months of postoperative follow-up |
The group that showed regular consultations at the clinic showed better food tolerance |
Romy et al., 2012, Switzerland |
442 patients (221 and 221 after GV and RYGB) |
Prospective |
Compare the two surgical techniques |
At 1, 2, 3, 4 and 5 years postoperatively |
The food had better tolerance and remained unchanged after RYGB |
Ramon et al., 2011, Spain |
105 patients, 64 underwent GV and 41 gastric bypass |
Prospective |
Assess the impact of GV and gastric bypass in food quality |
Preoperatively and 3, 6, 12 and 24 months postoperatively |
The food quality has worsened in the first months after surgery, improving gradually. There were no differences between the techniques evaluated |
Overs et al., 2012, Australia |
129 patients (13 after adjustable BG, 41 after RYGB, after GV 62 and 14 pre-surgical obese patients) |
Prospective |
Investigate and compare food tolerance after adjustable BG, RYGB and GV |
Between 2-4 years of postoperative |
The control group (non-operated obese) had better food tolerance. Adjustable patients after BG had lower food tolerance than the other techniques evaluated |
Godoy et al., 2012, Brazil |
47 patients after RYGB |
Prospective |
Investigate the level of food tolerance after RYGB |
Average 2 years postoperatively |
Patients with lower socioeconomic status have shown significant worst food tolerance |
Sioka et al. 2013 Greece |
110 patients after GV |
Prospective |
To evaluate the dietary profile after laparoscopic GV |
Group 1 (postoperative <3 months), group 2 (3-6 months), group 3 (6-12 months), Group 4 (1-2 years), Group 5 (2-3 years) and 6 group ( > 3 years) |
Improved food tolerance after the first year of laparoscopic GV |
Keren et al., 2014 Israel |
114 patients after laparoscopic GV |
Retrospective |
Evaluate the long-term food tolerance after laparoscopic GV |
At 30 and 60 months postoperatively |
Food tolerance at 30 months was better than at 60 months, with no significant difference |
Kafri et al. 2013 Israel |
37 patients (12 GV revised after laparoscopic and 25 after primary laparoscopic GV) |
Prospective |
Investigate food tolerance between the two groups |
Average 18 months postoperatively in both groups |
Food tolerance was lower in laparoscopic GV revised |
Freeman et al., 2014, Australia |
130 patients (14 pre-surgical obese controls, adjustable BG 13 after, 62 after GV and 41 after RYGB) |
Prospective |
Evaluate food tolerance between adjustable BG, GV and RYGB |
Between 2-4 years of post-operative |
Positive association between food intolerance and diet quality, low food tolerance considered as post-surgical complication after adjustable BG compared to GV and RYGB |
Kafri et al., 2011, Israel |
60 patients after laparoscopic GV |
Retrospective |
Evaluate food tolerance in two postoperative moments |
Group 1 over a year of monitoring and Group 2 less than one year |
Significant improvement of food tolerance over time |
Acosta et al., 2010, Venezuela |
41 patients (23 after RYGB and 18 after laparoscopic GV) |
Prospective |
To evaluate changes in quality of life and tolerance to food after bariatric surgery |
Preoperatively and 3.6 and 9 months postoperatively |
Worsening of tolerance at 3 months postoperatively, improving over time |
