Bariatric Surgery Outcomes in Patients with Severe Obesity Compared to Patients with Non-Severe Obesity at A New Institution in The United Arab Emirates.

Background: Bariatric surgery is an effective treatment for weight loss, but a higher body mass index (BMI) may lead to higher postoperative complication rates. This study aims to compare perioperative and postoperative outcomes between UAE patients with severe obesity (SO) [BMI ≥ 50 kg/m2] and non-severe obesity (NSO) [BMI < 50 kg/m2] undergoing primary bariatric surgery. Methods: From September 2015 to July 2019, 542 patients, 94 SO (56.5 ± 6.2 kg/m2) and 448 NSO (41.8 ± 4.1 kg/m2), were retrospectively reviewed. Results: Patients with SO were younger (33.8 ± 13.4 vs. 37.0 ± 11.5 years, p = 0.02) but otherwise had similar demographic characteristics. Their rates of Roux-en-Y gastric bypass (39.4% SO vs. 44.4% NSO, p = 0.37) and sleeve gastrectomy (60.6% vs. 55.6%, p = 0.37) were similar. There were no differences between perioperative complications (6.4% SO vs. 5.8% NSO, p = 0.83), major postoperative complications (5.3% vs. 3.5%, p = 0.42), readmissions (5.3% vs. 3.3%, p = 0.36), or reoperations (3.2% vs. 2.7%, p = 0.78). There were no mortalities. Their total body weight loss was comparable at 12 months (28.1 ± 10.2% vs. 29.0 ± 7.7%, p = 0.58). Conclusions: Although a higher BMI may pose operative challenges, UAE patients with SO do not have worsened outcomes in bariatric surgery, demonstrating similarly low morbidity to patients with NSO, and similar rates of improvement in their BMI.

Lower back pain as a manifestation of acute gouty sacroiliitis: Utilization of dual-energy computed tomography (DECT) in establishing a diagnosis.

Gout is the most common inflammatory arthritis which initially presents as a monoarthritis that usually favours peripheral joints namely the 1st MTP. It was reported in the literature to rarely involve the axial joint, such as the sacroiliac joint, and often mimics seronegative spondyloarthritis (SpA). Gout is a male disease and after menopause the risk in females is equal to males. Previous reports describe male patients developing gout involving the SI joint. We report a lady with a history of gout presenting with acute onset lower back pain. MRI of the sacroiliac joints revealed unilateral sacroilitis. With the help of Dual-Energy Computed Tomography (DECT) which is a newer imaging technique, a diagnosis of gout involving the sacroiliac joint was established. Gout involving the sacroiliac joints is rare, however it should be considered in the differential diagnosis in patients with unilateral sacroilitis given the similarity in presentation to SpA. Utilization of newer imaging modalities including DECT can highly guide in establishing a diagnosis and providing the correct treatment.
