RESUMO
INTRODUCTION: Obesity is associated with erectile dysfunction in many studies. This study aims to inspect the impact of weight-loss surgery on the erectile function in the Saudi male population. PATIENTS AND METHODS: Forty-two consecutive male patients who underwent weight-loss surgery during a period from February 2013 to July 2016 were included in the study. Unmarried patients were excluded from the study. A designed questionnaire includes the short version of the International Index of Erectile Function (IIEF), usage of phosphodiesterase inhibitors, overall satisfaction before and after the intervention, marriage duration, and fertility postsurgery. All the participants were contacted through phone in July 2018, and then the questionnaire was mailed to them. All the data were analyzed and compared to a control group of married obese patients, who were waiting for the bariatric surgeries, using specific statistical tests. RESULTS: Thirty patients responded and completed the survey. Their mean age was 41.9 years (range 26-62), and the mean preoperative body mass index (BMI) was 46.3 ± 7.5, with a significant reduction in the BMI postoperatively to a mean of 30 ± 5.5. The IIEF score improved, and the overall satisfaction and feelings were better (76.7%). Only 16.7% of cases needed PDEI before and after the operation. Thirteen (43.3%) patients got children after the surgery. Univariate and multivariate analysis showed that age was a significant factor in association with both erectile function and fertility after bariatric surgeries (P = 0.02). Fertility was better in patients who underwent laparoscopic sleeve gastrectomy than gastric bypass surgery (P = 0.01). CONCLUSION: The weight-loss surgeries have a significant effect on erectile function, and they improve patient sexual satisfaction. Most of these patients feel better sexual function after bariatric surgeries. Fertility outcome seems to have a positive correlation with this type of surgery. However, a larger sample size and more elaborate studies are warranted to substantiate this claim.
RESUMO
INTRODUCTION: Primary neuroendocrine tumors (NETs) of the liver are rare tumors that are challenging to diagnose. PRESENTATION OF CASE: A 41-year old woman presented with a four-month history of moderate abdominal pain in the right upper quadrant. A computed tomography scan of the abdomen revealed a large hypervascular liver lesion measuring 14 × 10 × 15 cm occupying segments IV and VIII and part of segment V of the liver. A liver biopsy revealed findings consistent with a well-differentiated NET. Transarterial chemoembolization was offered to the patient; however, the procedure was unsuccessful. Surgical management was therefore considered and resulted in a favorable outcome. DISCUSSION: Primary hepatic NETs are thought to originate from NET cells that may subsequently propagate to the intrahepatic biliary tree and become cancerous. These tumors are often missed during an initial evaluation due to a low clinical index of suspicion. In some cases, nonspecific symptoms such as abdominal pain and bloating may be an indication of early disease. No guidelines have been developed for the treatment of primary hepatic NETs; nevertheless, surgical resection remains the treatment of choice and plays a potentially curative role. CONCLUSION: Surgical resection may be beneficial in the management of a primary NET of the liver even when the procedure appears to be challenging, such as in the case of a centrally located liver tumor.
