RESUMEN
BACKGROUND AND OBJECTIVES: Intragastric balloon (IGB) is a safe option for obesity management. However, studies determining the factors influencing the procedure's outcomes are scarce. Therefore, our goal was to determine the factors affecting weight reduction after IGB insertion. MATERIALS AND METHODS: This retrospective study included 126 obese patients who underwent IGB treatment using the ORBERA® Intragastric Balloon System. Patients' records were retrieved; and demographic data, initial body mass index (BMI), complications, compliance with both diet and exercise programs, and percentage of excess weight reduction were recorded. RESULTS: The study included 108 female (85.7%) and 18 male (14.3%) patients. The mean age was 31.7 ± 8.1 years. The percentage of excess weight loss (EWL) was 55.8 ± 35.7%. The mean weight loss was 13.01 ± 7.51 kg. A significant association was found between EWL and age, initial weight, initial body mass index, and the number of pregnancies. No major complications were observed. However, the balloon had to be removed early in two patients (1.59%) due to its rupture and in two other patients (1.59%) due to severe gastritis. CONCLUSIONS: IGB therapy is a safe and effective option for obesity management, associated with low rates of complications. The EWL after IGB insertion is significantly higher among older patients, those with a relatively low initial body mass index, those with a longer duration of IGB insertion, and female patients with less parity. Larger prospective studies are needed to support our results.
RESUMEN
INTRODUCTION: Renal cell carcinoma (RCC) is the most common malignancy in the genitourinary tract, and is among the 10 most common cancers in both males and females. PRESENTATION OF CASE: We report a case of a 61-year-old male who presented with a cutaneous lesion on his left back side at a site where he had undergone several surgeries - including Left nephrectomy - twenty years ago for a gun-shot wound he sustained which penetrated his abdomen. DISCUSSION: At that time pathology reports turned out to be normal, specially left kidney pathology report which was negative for any malignancy. Twenty years later, patient presented with a clear fluctuating painless cutaneous mass of 1-2cm on his left back side, which grew gradually over time. Histopathologically, the incisional biopsy showed trabecular & papillary clear cells with prominent vascularity and hemosiderin deposition in the stroma, consistent with a malignant Renal cell Carcinoma (RCC). Immunohistochemically, it stained positive for Vimentin, CD10, PAX-8. Labs revealed positive renal cell carcinoma antibody. CT scans, urine tests, and bone scans failed to reveal the site of the primary lesion. Furthermore, the patient reports minimal constitutional symptoms and is grossly well. CONCLUSION: The authors have reported an interesting case of an RCC presenting in a healed gun-shot wound in a previously nephrectomized patient. To the best of authors' knowledge, such a case hasn't been reported in the literature before, with it being unique in its time course, preceding events, and absence of primary lesions.
