Aim: Bariatric surgery is an effective treatment for morbid obesity that has inevitable complications including postoperative bleeding and staple-line leakage. Erythrocyte sedimentation rate (ESR) can be a clinical indicator for prediction of leakage. Methods: This retrospective cohort study was done on 1999 patients who underwent sleeve gastrectomy in Erfan Niyayesh Hospital, Tehran, Iran. ESR levels of patients were evaluated in cases which had postoperative leak. Statistical analyses were performed using SPSS software. Results: Among the 2350 patients, 50 subjects experienced gastric leak (2.12%). ESR mean was 73.1 mm/h for cases, statistically significantly higher in patients with leakage compared to the control group. In addition, ESR serum level mean was 31.34 mm/h for control groups. Other variables including C-reactive protein and platelet count were not statistically significant. Conclusion: Higher ESR serum level can be seen in various conditions, and, in obese patients who undergo bariatric surgery, it can be a reliable predictor for postoperative gastric leak complication.

Laparoscopic sleeve gastrectomy (LSG) is an effective treatment option in patients with morbid obesity, with rare long-term sideeffects. In this report, we present a 42-year-old woman who reported positional vertigo and unilateral gradual hearing loss plus continuous tinnitus after LSG. The patient had no signs or symptoms of mental health disorders and the results of the haematological and serum biochemical tests were normal. However, audiometric test revealed mild sensorineural hearing loss with magnitude in high-frequency tones. Also, acoustic reflex threshold showed neural pathway damage, particularly at high frequencies, with no reflex. Pure tone audiometry showed signs of nerve damage in the inner ear. One possible justification for these complications might be eustachian tube dysfunction due to muscle relaxation. Muscle relaxation itself may occur as a result of adipose tissue loss around the ear muscles. Further evidence, however, would be required to better determine whether these complications are attributable to LSG, and to illuminate exact underlying reasons for such complications.

The outcome of laparoscopic sleeve gastrectomy (LSG), one of the most common bariatric surgery (BS) procedure, may differ depending on the patient's age, gender, and postoperative follow‐ups. In this study, we aimed to evaluate the efficacy of LSG technique on weight loss, obesity‐associated co‐morbidities and complications in patients undergoing LSG over 3 months and 1 year, regarding their age, gender, and postoperative follow‐ups. The LSG associated complications in participants regarding their preoperative BMI (<39.9 and >39.9), age (30‐40 and 40‐50), and gender were assessed after 3 and 12 months. Besides, the remission and improvement rates of comorbid conditions in patients were examined after 12 months of LSG. Our results showed that LSG led to a significant weight loss in the resolution of obesity‐associated co‐morbidities and different complications after 1 year. No significant difference was found in the improvement and the resolution of obesity‐associated co‐morbidities according to gender. Also, the class 3 patients had significantly higher rates of hearing loss after 12 months and had higher levels of depression and brittle nails 3 months after the surgery. The younger patients also showed a significantly higher percentage of dry skin, intolerance to bread, and menstrual disorder compared to the older group. In conclusion, this study emphasized the importance and necessity of further research into the factors influencing the outcome of LSG such as age, gender, and postoperative follow‐ups.
