I had my sleeve done in TJ Mexico and didn’t have an issue. When I raised concerns to my doctor in Canada he told me “Would you rather a surgeon do the surgery who does 3 a week or 2-3 a day?, find a reputable hospital and go”. 6 years later and I just had a revision to bypass but only because of GERD. After the revision surgery the surgeon took a look and said they did a good job with the initial surgery.
