SUMMARYTo study the prevalence of male obesity-secondary hypogonadism (MOSH) in patients with moderate to severe obesity, we performed a prospective prevalence study including 100 male patients with moderate to severe obesity at a university tertiary hospital. Total testosterone (TT) and sex hormone-binding globulin (SHBG) concentrations among others were assayed in all patients. Serumfree testosterone (FT) concentration was calculated from TT and SHBG levels. Semen analysis was conducted in 31 patients. We found a prevalence of 45% (95% CI: 35-55%) when considering decreased TT and/or FT concentrations. Serum concentrations of TT were correlated negatively with glucose (r = À0.328, p < 0.001) and insulin resistance (r = À0.261, p = 0.011). The same occurred with FT and glucose (r = À0.340, p < 0.001) and insulin resistance (r = À0.246, p = 0.016). Sixty-two percent (95% CI: 39-85%) of the patients with seminogram also presented abnormal results in semen analysis. The frequencies of low TT or low FT values were similar in patients with abnormal or normal semen analysis (p = 0.646 and p = 0.346, respectively). Ejaculate volume inversely correlated with BMI (q = À0.400, p = 0.029) and with excess body weight (q = À0.464, p = 0.010). Our data show the prevalence of MOSH in patients with moderate to severe obesity is high. Low circulating testosterone is associated with insulin resistance and low ejaculate volume with higher BMI and excess body weight. Semen analysis must be performed in these patients when considering fertility whether or not presenting low circulating testosterone.

Abdominal SCP has statistically significant better anatomical results when compared with HUVS for correcting apical defects at 12 months.

Bariatric surgery results in the complete resolution of male obesity-associated secondary hypogonadism (MOSH) in many patients. However, the effects of different bariatric surgical procedures on male sexual hormone profiles and sexual dysfunction have not been compared to date. We compared the pre- and post-operative (at least 6 months after initial surgery) sex hormone profiles of 20 severely obese men submitted to laparoscopic gastric bypass (LGB) with 15 similar patients submitted to restrictive techniques (sleeve gastrectomy in 10 and adjustable gastric banding in 5). We calculated free testosterone (FT) levels from total testosterone (TT) and sex hormone binding globulin (SHBG) concentrations. Fasting glucose and insulin levels served for homeostatic model assessment of insulin resistance (HOMAIR). MOSH was present in 25 and 16 of the 35 patients when considering TT and FT concentrations respectively, resolving after surgery in all but one of them. When considering all obese men as a whole, patients submitted to LGB or restrictive procedures did not differ in terms of excess weight loss, in the decrease of fasting glucose and insulin, HOMAIR and waist circumference, or in the increase of serum 25-hydroxyvitamin D, TT and FT levels. The improvement in TT correlated with the decrease in fasting glucose (r = -0.390, P = 0.021), insulin (r = -0.425, P = 0.015) and HOMAIR (r = -0.380, P = 0.029), and with the increase in SHBG (r = 0.692, P < 0.001). The increase in FT correlated with the decrease in fasting glucose (r = -0.360, P = 0.034). LGB and restrictive techniques are equally effective in producing a remission of MOSH.

Esophageal perforation constitutes a surgical emergency. Despite its gravity, no single strategy has been described as sufficient to deal with most situations to date. The aim of this study was to assess the etiology, management, and outcome of esophageal perforation over a 28-year period, to characterize optimal treatment options in this severe disease. A retrospective clinical review of all patients treated for esophageal perforation at Ramón y Cajal Hospital between January 1987 and December 2015 was performed (n = 57). Iatrogenic injury was the most frequent cause of esophageal perforation (n = 32). Abdominal esophagus was the main location (23 patients; 40.4%). Eight patients (14%) were managed with antibiotics and parenteral nutrition. In seven patients (12.3%), an endoscopic stent was implanted. Surgical therapy was performed in 38 patients (66.7%). Morbidity and 90-day mortality rates were 61.4 and 28 per cent, respectively. Five patients were reoperated (8.8%). Median hospital stay was 23.5 days. The mortality rate was higher among patients with spontaneous and tumoral perforation (54.5 and 100%; P = 0.009), delayed diagnosis (>24 hours; P = 0.0001), and abdominal/thoracic location (37.5%; P = 0.05). No statistical differences were found between surgical and conservative/endoscopic management (31% vs 20%; P = 0.205) although hospital staying was longer in surgical group (36.30 days vs 15.63 days; P = 0.029). Esophageal perforation was associated with high morbidity and mortality rates. Global outcomes depend on etiology, site of perforation, and delay in diagnosis. An individualized approach for each patient should be chosen to prevent septic complications of this potentially fatal disease.

In our experience, the recurrence rate in patients with a Crurasoft (Bard) is acceptable. However, the rate of postoperative complications and mortality is excessive. The use of meshes in the hiatus keeps on being controversial due to the severe complications related to them. It would be advisable to compare our results in the non-mesh group in terms of recurrences and complications, to determine if meshes in the hiatus should be given in these patients due to its high rate of complications.
