RESUMEN
Objectives Obesity is viewed as a risk factor for several life-threatening diseases. Bariatric surgeries are regarded as a safe and effective way of treating morbid obesity and are associated with alterations in molecules such as Vitamin D and retinol-binding protein 4 (RBP4). The aim of this study was to examine an association between Vitamin D and RBP4 in healthy obese individuals undergoing gastric sleeve surgery. Methods In this observational retrospective cohort study, we used clinical and biochemical profiles of morbidly obese healthy male subjects (BMI > 38.3) who underwent laparoscopic sleeve gastrectomy. RBP4 levels were evaluated by ELISA before and 6-12 months after surgery. Data were analysed using SPSS 23 statistical software. Results RBP4/Vitamin D ratio was reduced significantly after surgery (p < 0.001), however, there was no correlation between Vitamin D and RBP4 (p = 0.353). BMI was reduced significantly after surgery (p < 0.001) but was not correlated with RBP4 or Vitamin D levels before and after surgery (p > 0.05). A significant increase in the levels of calcium post-surgery was observed (p< 0.001). Conclusions In conclusion, plasma levels of Vitamin D were not correlated with RBP4 before or after laparoscopic gastric sleeve surgery.
RESUMEN
Small intestinal obstruction is a common surgical emergency that has a wide range of underlying etiologies. The most frequent causes of small intestinal obstruction include adhesions, hernias, and malignancies. The diagnosis of small intestinal obstruction is primarily dependent on the clinical findings, but imaging investigations are crucial to confirm the diagnosis and evaluate the complications. We report the case of a middle-aged woman with a complaint of abdominal pain for one week that was associated with abdominal distension and decreased bowel motion. Examination of the abdomen showed a distended abdomen. There was generalized tenderness, but no guarding or rigidity was noted. Initial laboratory investigation showed no derangement in the basic hematological and biochemical parameters. Abdominal CT was performed, which showed a segment of jejunojejunal intussusception causing a small intestinal obstruction. There was a well-defined, oval-shaped fat-attenuation mass lesion acting as a lead-point. Such radiological findings conferred the diagnosis of jejunojejunal intussusception due to jejunal lipoma. The patient underwent laparotomy, which confirmed the radiological finding. The intussusception was reduced, but a gangrenous intestine was observed. Resection of the affected intestine was performed, followed by a primary anastomosis. The patient recovered with no complications. Following the operation, oral feeding was started gradually according to the patient's tolerance. She was discharged after 10 days of hospitalization. At the follow-up visit after three months, the patient had no active symptoms. This case illustrated a rare etiology of small intestinal obstruction due to gastrointestinal lipoma. A computed tomography scan is strongly advised to reach the diagnosis and identify the lead points.
