Background: In recent years, several articles have reported considerable results with the Mini/One Anastomosis Gastric Bypass (MGB/OAGB) in terms of both weight loss and resolution of comorbidities. Despite those positive reports, some controversies still limit the widespread acceptance of this procedure. Therefore, a multicenter retrospective study, with the aim to investigate complications following this procedure, has been designed. Patients and Methods: To report the complications rate following the MGB/OAGB and their management, and to assess the role of this approach in determining eventual complications related especially to the loop reconstruction, in the early and late postoperative periods, the clinical records of 2678 patients who underwent MGB/OAGB between 2006 and 2015 have been studied. Results: Intraoperative and early complications rates were 0.5 and 3.1%, respectively. Follow-up at 5 years was 62.6%. Late complications rate was 10.1%. A statistical correlation was found for perioperative bleeding both with operative time (p < 0.001) or a learning curve of less than 50 cases (p < 0.001). A statistical correlation was found for postoperative duodenal-gastro-esophageal reflux (DGER) with a preexisting gastro-esophageal-reflux disease (GERD) or with a gastric pouch shorter than 9 cm, (p < 0.001 and p = 0.001), respectively. An excessive weight loss correlated with a biliopancreatic limb longer than 250 cm (p < 0.001). Conclusions: Our results confirm MGB/OAGB to be a reliable bariatric procedure. According to other large and long-term published series, MGB/OAGB seems to compare very favorably, in terms of complication rate, with two mainstream procedures as standard Roux-en-Y gastric bypass (RYGBP) and laparoscopic sleeve gastrectomy (LSG). © 2017 Springer Science+Business Media New York

Background Due to the failure of the "old Mason loop," the mini-gastric bypass (MGB) has been viewed with skepticism. During the past 12 years, a growing number of authors from around the world have continued to report excellent short- and long-term results with MGB. Methods One university center, three regional hospitals, and two private hospitals participated in this study. From July 2006 to December 2012, 475 men (48.8 %) and 499 women (51.2 %) underwent 974 laparoscopic MGBs. The mean age of these patients was 39.4, and their preoperative body mass index was 48 ± 4.58 kg/m2. Type 2 diabetes mellitus (T2DM) affected 224 (22.9 %) of the 974 patients, whereas 291 of the 974 patients (29.8 %) presented with hypertension. The preoperative gastrointestinal statuswas explored in all the patients through esophagogastroduodenoscopia. The major end points of the study were definitions of both MGB safety and efficacy in the long termaswell as the endoscopic changes in symptomatic patients eventually produced by surgery. Results The rate of conversion to open surgery was 1.2 % (12/974), and the mortality rate was 0.2 % (2/974). The perioperative morbidity rate was 5.5 % (54/974), with 20 (2 %) of the 974 patients requiring an early surgical revision. The mean hospital length of stay was 4.0 ± 1.7 days. At this writing, 818 patients are being followed up. Late complications have affected 74 (9 %) of the 818 patients. The majority of these complications (66/74, 89.1 %) have occurred within 1 year after surgery. Bile reflux gastritis was symptomatic, with endoscopic findings reported for 8 (0.9 %) and acid peptic ulcers for 14 (1.7 %) of the 818 patients. A late revision surgery was required for 7 (0.8 %) of the 818 patients. No patient required revision surgery due to biliary gastritis. At 60 months, the percentage of excess weight loss was 77 ± 5.1 %, the T2DM remission was 84.4 %, and the resolution of hypertension was 87.5 %. Conclusions Despite initial skepticism, this study, together with many other large-scale, long-term similar studies from around the world (e.g., Taiwan, United States, France, Spain, India, Lebanon) demonstrated theMGBto be a short, simple, low-risk, effective, and durable bariatric procedure. © Springer Science+Business Media New York 2013.

Thirteen melanocytic skin neoplasms with a consultation diagnosis by A. Bernard Ackerman were submitted to immunohistochemistry for HMB-45, Ki67, cyclin D1, e-cadherin, and p16; 9/13 cases underwent fluorescence in situ hybridization (FISH) test targeting 6p25 (RREB1), 6q23 (MYB), centromere 6 (Cep6), and 11q13 (CCND1), as well as the centromere 7 (Cep7). A "consensus diagnosis" among 3 experts was also advocated both before and after morphomolecular information. Three neoplasms with a consultation diagnosis of Spitz nevus showed at least 3 abnormal immunohistochemical patterns; 2 of these cases were also FISH-positive for CCND1 gain, but none of them had a final consensus diagnosis of melanoma. Two neoplasms with a consultation diagnosis of congenital nevus received a consensus diagnosis of melanoma. Molecular morphology techniques can highlight the atypical features of melanocytic neoplasms and support existence of a morphobiologic "spectrum": This should be mirrored in the final report by abandoning the dichotomic (benign vs malignant) diagnostic approach. © The Author(s) 2013.
