Abstract
BACKGROUND Subclinical Cushing's syndrome (SCS) is a condition of biochemical cortisol excess without the classical clinical features of overt hypercortisolism; it may be associated with some consequences of metabolic syndrome. The most appropriate treatment remains controversial. This study aimed to assess the outcomes of adrenalectomy for SCS. METHODS A systematic review was performed. MEDLINE, Embase and Cochrane Databases (1980-2013) were searched for studies reporting the outcomes of unilateral adrenalectomy with respect to hypertension, diabetes, dyslipidaemia, obesity and osteoporosis in patients with SCS. Studies with a questionable diagnosis of SCS, bilateral adrenal involvement and insufficient data were excluded. RESULTS Of the 105 papers screened, seven were selected; there were six retrospective studies and one randomized clinical trial, including 230 patients. Data analysis was limited by heterogeneity in definition of SCS and endpoints. Hypercortisolism was cured in all operated patients. Laparoscopy was the preferred approach, with a morbidity rate of 0ยท8 per cent. A beneficial effect of surgery on blood pressure, glucometabolic control and obesity was evident in all studies, with cure or improvement in 72, 46 and 39 per cent of patients respectively, compared with conservative management. The results for lipid metabolism were equivocal, because of a decrease in triglyceridaemia but discordant effects on cholesterol metabolism among the different studies. No beneficial effects on osteoporosis were found. CONCLUSION Laparoscopic adrenalectomy seems to be beneficial in reversing several metabolic effects of hypercortisolism, with a low morbidity rate. However, the heterogeneity and low quality of the available studies preclude definitive recommendations.

Abstract
BACKGROUND Bariatric surgeries are now redefined as metabolic surgeries given the excellent resolution of metabolic derangements accompanying obesity. Duodenojejunal bypass (DJB) is a novel metabolic surgery based on foregut hypothesis. Reports describe DJB as a stand-alone procedure for the treatment of diabetes in nonobese subjects. For obese subjects, DJB is combined with sleeve gastrectomy. This combination of DJB and sleeve gastrectomy is proposed as an ideal alternative to Roux-en-Y gastric bypass (RYGB) with these advantages: (1) easy postoperative endoscopic surveillance, (2) preservation of the pyloric mechanism, which prevents dumping syndrome, and (3) reduced alimentary limb tension. This study aimed to analyze the short-term outcomes of laparoscopic DJB with sleeve gastrectomy for morbidly obese patients. METHODS At our institution, 38 patients who underwent laparoscopic DJB with sleeve gastrectomy were followed up. The inclusion criteria for the study were according to the Asian Pacific Bariatric Surgery Society guidelines. Sleeve gastrectomy was performed over a 36-Fr bougie, with the first part of the duodenum mobilized and transected. The jejunum was divided 50 cm distal to duodenojejunal flexure. A 75- to 150-cm alimentary limb was fashioned and brought in a retrocolic manner. End-to-end hand-sewn duodenojejunostomy was performed. Intestinal continuity was restored with a stapled jejunojejunostomy, and mesenteric rents were closed. RESULTS The study population consisted of 38 patients (15 men and 23 women) ranging in age from 31 to 48 years. During a mean follow-up period of 17 months, the excess body weight loss was 72%, with a 92% resolution of diabetes. One patient presented with internal herniation through the retrocolic window 1 month after the operation and was managed surgically without any complication. No other minor or major complications occurred, and there was no mortality. CONCLUSION Laparoscopic DJB with sleeve gastrectomy is safe and effective in achieving durable weight loss and excellent resolution of comorbidities. Long-term follow-up studies are needed.
