Objective: Obesity is a global health epidemic with considerable co-morbidities. The increasing demand for bariatric surgery has led to the emergence of new techniques. We modified previously described Mini Gastric By-pass(MGB) technique via leaving a bridge at the most cranial 2 cm of the fundus of the human stomach to the follow-up and treatment of the remnant stomach and duodenum. We would like to entitle this new technique as Bridged MGB and aimed to apply on rabbits as an experimental study. Material and Methods: The study was performed in the experimental animal laboratory of university after ethical approval was taken from the local ethics committee. Described new technique was applied to 2.1 and 3.2 kg 2 New Zealand rabbits. Results: As a result of the operations, one of the rabbits died on the day of the operation; the other rabbit was exitus postoperatively on the third day. In autopsies, although no problem was detected at the anastomoses, necrosis was detected in the large curvature of both rabbits. Conclusion: Rabbit, one of the popular experimental animals, has been shown to be different from the human gastrointestinal system in both arterial and topographic aspects and it has been emphasized that it varies according to the species and even the diet and the climate. We believe that our study failed as a result of these differences and that animals more similar to humans should be used in gastrointestinal experimental studies.

OBJECTIVE: Panniculitis is an inflammation of the subcutaneous fat common in patients defined as super-super obese (>60 kg/m2). Poor hygiene and skin infections are common in the super morbidly obese group due to impaired metabolism of subcutaneous fat tissue, especially at abdominal folding. In our study, we will discuss the short-term results of panniculitis that develops as a result of these, simultaneously with bariatric surgery. MATERIAL AND METHODS: In our study, six super morbid obese patients with Body Mass Index (BMI) of 80 kg/m(2), 77 kg/m(2), 74 kg/m(2), 72 kg/m(2), 68 kg/m(2), 65 kg/m(2), respectively, and sub umbilical skin tissue panniculitis were evaluated. These patients underwent bariatric surgery as a result of the obesity council decision. In the preoperative evaluation of the patients, it was observed that the blood supply to the subcutaneous fat tissues under the umbilicus was impaired, and the dermis/epidermis was hypertrophied. RESULTS: Mean BMI of patients 73 kg/m(2). Sleeve Gastrectomy (SG) was performed in 4 patients, Mini Gastric Bypass (MGB) was performed in 1 patient, and modified transit bipartition was performed in 1 patient. Infected erythematous lesions were detected on the skin secondary to ischemia, especially in some areas. After the patients performed the operations, a panniculectomy of approximately 70x30x20 cm was performed from under the umbilicus to the transverse line and up to the fascia. CONCLUSION: Panniculectomy and bariatric surgery are recommended in the appropriate patient group. Extensive prospective studies are required to define further the burden of infectious morbidity and mortality conferred by obesity.
