Complications Following the Mini/One Anastomosis Gastric Bypass (MGB/OAGB): a Multi-institutional Survey on 2678 Patients with a Mid-term (5 Years) Follow-up.

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).

Effects of omega-loop bypass on esophagogastric junction function.

BACKGROUND: At present, no objective data are available on the effect of omega-loop gastric bypass (OGB) on gastroesophageal junction and reflux. OBJECTIVES: To evaluate the possible effects of OGB on esophageal motor function and a possible increase in gastroesophageal reflux. SETTING: University Hospital, Italy; Public Hospital, Italy. METHODS: Patients underwent clinical assessment for reflux symptoms, and endoscopy plus high-resolution impedance manometry (HRiM) and 24-hour pH-impedance monitoring (MII-pH) before and 1 year after OGB. A group of obese patients who underwent sleeve gastrectomy (SG) were included as the control population. RESULTS: Fifteen OGB patients were included in the study. After surgery, none of the patients reported de novo heartburn or regurgitation. At endoscopic follow-up 1 year after surgery, esophagitis was absent in all patients and no biliary gastritis or presence of bile was recorded. Manometric features and patterns did not vary significantly after surgery, whereas intragastric pressures (IGP) and gastroesophageal pressure gradient (GEPG) statistically diminished (from a median of 15 to 9.5, P<.01, and from 10.3 to 6.4, P<.01, respectively) after OGB. In contrast, SG induced a significant elevation in both parameters (from a median of 14.8 to 18.8, P<.01, and from 10.1 to 13.1, P<.01, respectively). A dramatic decrease in the number of reflux events (from a median of 41 to 7; P<.01) was observed after OGB, whereas in patients who underwent SG a significant increase in esophageal acid exposure and number of reflux episodes (from a median of 33 to 53; P<.01) was noted. CONCLUSIONS: In contrast to SG, OGB did not compromise the gastroesophageal junction function and did not increase gastroesophageal reflux, which was explained by the lack of increased IGP and in GEPG as assessed by HRiM.

[A rare case of lymphadenopathy: the Kituchi-Fujimoto disease]. / Una rara causa di linfoadenopatia: malattia di Kikuchi-Fujimoto.

Lymphadenopathy is fairly widespread among the population and recognize multiple causes, often benign and self-limiting. We report on case about one young women with Kikuchi-Fujimoto disease or histiiocytic necrotizing lymphadenitis. This is a rare self-limiting lymphadenopathy which is usually diagnosed in young women. It is a self-limiting condition, usually resolving within 2-3 months, a low recurrence rate of 3% to 4% has been reported, of unknown origin, that does not require any specific management.

[A rare case of obstructive jaundice secondary to common hepatic artery aneurysm]. / Aneurisma dell'arteria epatica comune: una rara causa di ittero ostruttivo.

The common hepatic artery aneurysms (HAA) are uncommon atherosclerotic lesions and often they are clinically silent. Their diagnosis is often difficult prior to rupture, due to nonspecific clinical presentation. We report a case of a giant aneurysm of the common hepatic artery causing obstructive jaundice through compression of the biliary tract. The presence of the lesion was confirmed with the use of spiral computed tomographic angiography. Hepatic artery aneurysm is a lesion that should be considered in cases of unexplained obstructive jaundice.

Short and long term results of the laparoscopic Heller-Dor myotomy. The influence of age and previous conservative therapies.

AIMS: To evaluate the long-term outcome and quality of life (QoL) data, and to assess the potential influence of age and different conservative procedures on laparoscopic surgery. BACKGROUND: Current therapies for achalasia can palliate dysphagia, but other symptoms may persist, making it difficult to quantify and compare. To understand if they could influence results, we analyzed short- and long-term results and correlated them to age and previous conservative treatments using a specific QoL test. METHODS: Functional examinations (endoscopy, 24-hr pH manometry, upper GI X-rays) and the gastrointestinal quality of life index (GIQLI) were used before and after a laparoscopic Heller-Dor myotomy. Data were analyzed by the Mann-Whitney U test, Wilcoxon signed rank test, and Spearman's rho coefficient for bivariate correlations (p < 0.05). RESULTS: From January 1996 to January 2004, 31 consecutive patients out of 35 diagnosed with achalasia, in clinical stages I-III, were operated on by laparoscopy . Two groups were identified using the break point of 70 years of age, (20 younger and 15 older) and two subgroups according to the conservative therapy performed (20, none; 15, some). Patients underwent a clinical manometry evaluation at six and 12 months, and then yearly, and pH-metry at six, 24, and 60 months. In 78% of patients dysphagia disappeared and the incidence of reflux was 13%. Age and previous treatments did not influence surgical outcome. Patients completed a GIQLI questionnaire before surgery, six months after surgery, and then yearly (for five years). The median preoperative GIQLI score was 78 (range 38-109) out of a theoretical maximum score of 144. At a median follow-up of 49 months (range 24-72 months), the score had significantly improved to 115 (range 71-140). There was no significant statistical difference between the groups. CONCLUSIONS: Laparoscopic Heller-Dor myotomy is an effective palliation for achalasia; the long-term outcome is not significantly affected by preoperative conservative treatments or by the age of the patients. The GIQLI questionnaire is a reliable instrument to compare the impact of achalasia symptoms on health-related QoL before and after surgery.

[Timing and results of the surgical treatment of the diverticular disease of the colon]. / Timing e risultati della terapia chirurgica della malattia diverticolare del colon.

AIMS: To evaluate retrospectively the outcome of the curative open and laparoscopic surgical approach to the diverticular disease according to timed steps based on the pathologic stage. PATIENT AND MATERIAL: From 1989 83 out of 242 outpatients underwent surgery in emergency or after medical failure and at least two acute attacks requiring hospital admittance, or complicated diverticulitis. Modified Hinchey classification staged the disease. Clinic and instrumental criteria, surgical procedures, early and late complications were statistically evaluated (Students t-test and exact Fischer test, p < 0.05) in comparison with the different steps of therapeutic strategy. RESULTS: Twenty nine patients were classified as Hinchey 0, 26 as I, 14 as II, 11 as III, 3 as IV. Clinical characteristics of the lap and open groups overlapped, with higher rate of earlier age in first and advanced stages in the second group. 16 patients (19.3%) underwent surgery at the first attack in emergency or in delayed emergency (5 TC-guided drainages). 30 open and 53 lap procedures were done: 21 two-stage: 18 primary resections + ileostomy and 3 Hartmann; 61 single stage: 49 sigmoidectomy, 12 left colectomy. 4 conversions (7.5%), 12 early (14.5%) and 10 late (12.1%) complications were observed. DISCUSSION: Complications rate was higher in the open group including more advanced stages. Elective surgery performed following conservative therapy, 4 weeks from the first acute attack in younger people (age < 55yrs.) and after two attacks in elder (age > 55yrs.) showed a significant lower complications' incidence (p < 0.05) compared to the 8 weeks delayed operations. CONCLUSION: Surgery of diverticulitis must follow standardized criteria. The laparoscopic approach could be performed in more severe stages, provided that conditions of delayed emergency were achieved.
