Burcin Batman — sleeve gastrectomy and metabolic surgery in Istanbul

Burcin Batman performs sleeve gastrectomy and metabolic surgery at Hisar Hospital Intercontinental in Istanbul. His hospital profile describes a practice focused on obesity and metabolic surgery. ^[1]

Hisar credits him with over 3,000 obesity and metabolic surgery operations. This is an undated hospital claim, not an audited personal sleeve-gastrectomy total or a measure of surgical safety. ^[2]

Sleeve surgery: published complications

Batman is first author of a retrospective study of 1,200 consecutive patients who had sleeve gastrectomy with omentopexy, an additional fixation technique, between March 2013 and December 2018. The study reported no deaths, but there were staple-line leaks in 3 patients (0.25%), bleeding in 7 (0.58%) and narrowing of the stomach in 16 (1.33%). Wound infection, fat necrosis, splenic arterial injury and an abdominal abscess were each reported in 1 patient (0.08%). These are study-team figures, not a personal complication rate. ^[3]

For you, this provides concrete risks to discuss before sleeve surgery. It does not establish the current complication rate at Hisar, and the abstract does not specify how long complications were tracked. Ask whether your proposed operation uses the same technique and how leaks or narrowing would be managed after you return home. ^[4]

Blood sugar after sleeve surgery

Another first-author study reviewed 174 patients with a body mass index of 30–35 who underwent sleeve gastrectomy between March 2013 and September 2019. Mean fasting blood glucose fell from 105.40 to 92.96 mg/dL at 12 months. No early or late deaths were reported; the full paper does not provide detailed complication counts. ^[5]

For you, the finding supports discussing blood-sugar improvement as a possible benefit, not assuming diabetes will resolve. This was a selected, retrospective group without a comparison treatment, and it does not give your personal chance of remission. These historical cohorts should not be added together because patient overlap has not been ruled out. ^[6]

Weight loss and fatty liver

A further first-author study enrolled 72 patients undergoing sleeve surgery and used liver scans to assess fatty liver and stiffness. Mean excess weight loss was 57.2% at three months and 81.4% at six months. Excess weight loss is not the percentage of total body weight lost. Dates for this group are not given in the abstract, which also does not report complications. ^[7]

For you, this is short-term evidence from a selected group, not a forecast of how much weight you will lose or a guarantee that liver disease will resolve. Ask for a follow-up plan that covers nutrition, metabolic health and liver monitoring when relevant. ^[8]

Ask Burcin Batman to review your case through Bookimed. A request starts a medical and availability review; it is not an appointment. Ask for confirmation that Batman will operate at Hisar and for a written plan covering the procedure, discharge and care after returning home. ^{[11] [12]}

Research behind this page

Batman is first author of Benefits of Suture Reinforcement in Laparoscopic Sleeve Gastrectomy, the complication study above. His official hospital profile lists this publication, linking the researcher to the current clinician. First authorship does not establish that he personally performed every operation. ^{[13] [14]}

His other cited papers are The Effects of Laparoscopic Sleeve Gastrectomy on Glucose Metabolism and The Effect of Laparoscopic Sleeve Gastrectomy on Nonalcoholic Fatty Liver Disease. The glucose paper was read in full; the complication and liver findings here come from their abstracts. The research predates this booking request and is not presented as a current Hisar audit. ^{[15] [16]}
