The International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) issued a position statement on the role of one anastomosis gastric bypass (OAGB) in the field of ...bariatric/metabolic surgery in 2018 De Luca et al. (Obes Surg. 28(5):1188-206,
2018
). This position statement was issued by the IFSO OAGB task force and approved by the IFSO Scientific Committee and IFSO Executive Board. In 2018, the OAGB task force recognized the necessity to update the position statement in the following 2 years since additional high-quality data could emerge. The updated IFSO position statement on OAGB was issued also in response to inquiries to the IFSO by society members, universities, hospitals, physicians, insurances, patients, policy makers, and media. The IFSO position statement on OAGB has been reviewed within 2 years according to the availability of additional scientific evidence. The recommendation of the statement is derived from peer-reviewed scientific literature and available knowledge. The IFSO update position statement on OAGB will again be reviewed in 2 years provided additional high-quality studies emerge.

Background The impact of diabetes mellitus on the technical and clinical outcomes of infrainguinal arterial reconstruction (IAR) for critical limb ischemia (CLI) remains controversial. This study ...analyzed the outcome of IAR in diabetic patients with CLI over a 17-year period. Methods Details on all consecutive patients undergoing primary IAR at our institution were stored prospectively in a vascular registry from 1995 to 2011. Demographics, risk factors, indications for surgery, inflow sources and outflow target vessels, types of conduit, and adverse outcomes were analyzed. Postoperative surveillance included clinical examination, duplex scans, and ankle-brachial index measurements in all patients at discharge, 1 and 6 months after surgery, and every 6 months thereafter. End points were patency, limb salvage, survival, and amputation-free survival rates, and were assessed using Kaplan-Meier life-table analysis. The χ2 or Fisher exact, Student t , and log-rank tests were used to establish statistical significance. Results Overall, 1407 IARs were performed in 1310 patients with CLI by the same surgeon, 705 (50.2%) in 643 diabetic patients and 702 in 667 nondiabetic patients. Autogenous vein conduits were used in 87% of the IARs. There were no perioperative deaths. Diabetic patients had significantly more major (16.7% vs 11.8%; P = .02) and minor complications (9.7% vs 6.5%; P = .02) than nondiabetic patients. At 5 and 10 years, there were no significant differences between diabetic and nondiabetic patients in the rates of primary patency (65% and 46% vs 69.5% and 57%; log-rank test, P = .09), secondary patency (76% and 60% vs 80% and 68%; log-rank test, P = .20), limb salvage (88% and 76% vs 91% and 83%; log-rank test, P = .12) survival (51% and 34% vs 57% and 38%; log-rank test, P = .41), or amputation-free survival (45.5% and 27% vs 51% and 29%; log-rank test, P = .19). The type of conduit did not affect patency or limb salvage rates in either group. Conclusions Diabetic patients receiving IAR for CLI can have the same survival and amputation-free survival rates as nondiabetic patients. Their comparable technical and clinical outcomes strongly demonstrate that diabetics with CLI can expect the same quantity and quality of life as nondiabetics with CLI, and aggressive attempts at limb salvage in patients with diabetes mellitus, including distal and foot level bypass grafting, should not be discouraged.

Objective Although the management of carotid disease is well established for symptomatic lesions ≥70%, the surgical treatment for a symptomatic ≤50% stenosis is not supported by data from randomized ...trials. Factors other than lumen narrowing, such as plaque instability, seem to be involved in cerebral and retinal ischemic events. This study analyzes the early-term and long-term outcomes of carotid endarterectomy (CEA) performed in patients with low-grade (≤50% on North American Symptomatic Carotid Endarterectomy Trial criteria) symptomatic carotid stenosis. Methods The study involves 57 consecutive patients undergoing CEA for symptomatic low-grade carotid disease at our institution over 5 years, and 21 (36.8%) had experienced more than one ischemic event. Overall, 48 (84.2%) had a minor stroke, and nine (15.8%) had an episode of retinal ischemia. Diagnosis was made by a vascular neurologist based on an ultrasound examination combined with noninvasive imaging studies, after ruling out other possible causes of embolization. Before CEA, all patients were receiving antiplatelet treatment, and 87% were taking statins. All patients underwent eversion CEA under general deep anesthesia, with selective shunting. All carotid plaques were examined histologically. Long-term follow-up (median, 28 months; mean, 32 ± 5 months; range, 3-56 months) was obtained for 55 patients. Results No 30-day strokes or deaths occurred, and no patients had recurrent neurologic events related to the revascularized hemisphere during the follow-up. No late carotid occlusions were detected, but one asymptomatic moderate restenosis was documented. There were seven late deaths (12.7%), none of which were stroke-related. Survival rates were 98% at 1 year and 90% at 3 years. All removed carotid plaques showed different features of ulceration or rupture, with underlying hemorrhage associated with a thrombus. Conclusions This study shows that CEA is a safe, effective, and durable treatment for patients with symptomatic low-grade carotid stenosis associated with unstable plaque. Patients had excellent protection against further ischemic events and survived long enough to justify the initial surgical risk. Plaque instability seems to play a major part in the onset of ischemic events, regardless the entity of lumen narrowing.

Background
The European Association for Endoscopic Surgery Bariatric Guidelines Group identified a gap in bariatric surgery recommendations with a structured, contextualized consideration of multiple ...bariatric interventions.
Objective
To provide evidence-informed, transparent and trustworthy recommendations on the use of sleeve gastrectomy, Roux-en-Y gastric bypass, adjustable gastric banding, gastric plication, biliopancreatic diversion with duodenal switch, one anastomosis gastric bypass, and single anastomosis duodeno-ileal bypass with sleeve gastrectomy in patients with severe obesity and metabolic diseases. Only laparoscopic procedures in adults were considered.
Methods
A European interdisciplinary panel including general surgeons, obesity physicians, anesthetists, a psychologist and a patient representative informed outcome importance and minimal important differences. We conducted a systematic review and frequentist fixed and random-effects network meta-analysis of randomized-controlled trials (RCTs) using the graph theory approach for each outcome. We calculated the odds ratio or the (standardized) mean differences with 95% confidence intervals for binary and continuous outcomes, respectively. We assessed the certainty of evidence using the CINeMA and GRADE methodologies. We considered the risk/benefit outcomes within a GRADE evidence to decision framework to arrive at recommendations, which were validated through an anonymous Delphi process of the panel.
Results
We identified 43 records reporting on 24 RCTs. Most network information surrounded sleeve gastrectomy and Roux-en-Y gastric bypass. Under consideration of the certainty of the evidence and evidence to decision parameters, we suggest sleeve gastrectomy or laparoscopic Roux-en-Y gastric bypass over adjustable gastric banding, biliopancreatic diversion with duodenal switch and gastric plication for the management of severe obesity and associated metabolic diseases. One anastomosis gastric bypass and single anastomosis duodeno-ileal bypass with sleeve gastrectomy are suggested as alternatives, although evidence on benefits and harms, and specific selection criteria is limited compared to sleeve gastrectomy and Roux-en-Y gastric bypass.

Conclusions
This rapid guideline provides evidence-informed, pertinent recommendations on the use of bariatric and metabolic surgery for the management of severe obesity and metabolic diseases. The guideline replaces relevant recommendations published in the EAES Bariatric Guidelines 2020.

Development of the Italian clinical practice guidelines on bariatric and metabolic surgery, as well as design and methodological aspects.
Obesity and its complications are a growing problem in many ...countries. Italian Society of Bariatric and Metabolic Surgery for Obesity (Società Italiana di Chirurgia dell'Obesità e delle Malattie Metaboliche-SICOB) developed the first Italian guidelines for the treatment of obesity.
The creation of SICOB Guidelines is based on an extended work made by a panel of 24 members and a coordinator. Grading of Recommendations, Assessment, Development and Evaluations (GRADE) methodology has been used to decide the aims, reference population, and target health professionals. Clinical questions have been created using the PICO (Patient, Intervention, Comparison, Outcome) conceptual framework. The definition of questions used the two-step web-based Delphi method, made by repeated rounds of questionnaires and a consensus opinion from the panel.
The panel proposed 37 questions. A consensus was immediately reached for 33 (89.2%), with 31 approved, two rejected and three which did not reach an immediate consensus. The further discussion allowed a consensus with one approved and two rejected.
The areas covered by the clinical questions included indications of metabolic/bariatric surgery, types of surgery, and surgical management. The choice of a surgical or a non-surgical approach has been debated for the determination of the therapeutic strategy and the correct indications.
Background The indication for carotid endarterectomy (CEA) is uncertain in patients with asymptomatic severe (≥60% luminal narrowing according to the North American Symptomatic Carotid Endarterectomy ...Trial criteria) carotid stenosis (ASCS), especially in the very elderly, because current evidence suggests that the risk of future stroke has been dropping in the past two decades owing to the recent advances in medical therapy. The aim of this observational study was to compare early and late outcomes in patients ≥80 years old with ASCS treated with CEA plus best medical treatment (BMT) or with BMT alone. Methods From 2005 to 2012, 69 octogenarians with ASCS underwent CEA plus BMT (group 1), and another 54 received BMT alone (group 2). All operations were eversion CEAs. BMT included lipid-lowering drugs, new antiplatelet and antihypertensive agents, avoidance of smoking, careful blood pressure and glycemic control, and lifestyle changes. Follow-up with serial ultrasonographic examination was obtained in 118 patients for a median 4.4-year period. Results There were no perioperative (30-day) strokes or deaths and one transient ischemic attack (1.4%). One late minor stroke developed in a CEA patient (1.5%). No late restenoses or occlusions were detected. Five patients in group 2 (9.6%) became symptomatic (one transient ischemic attack and four minor strokes) and subsequently underwent successful CEA; all their carotid plaques were complicated by ulceration and intraplaque hemorrhage (with plaque progression in four cases), confirmed by computed tomography images. The rate of freedom from cerebral ischemic events at 5 years showed a significant benefit for elderly patients who had CEA vis-à-vis those who did not (98% vs 84%; P = .04), and so did the 5-year rate of freedom from ipsilateral carotid disease progression (100% vs 91%; P = .01). At 5 years, the mortality rate was comparable for elderly patients whether they had CEA or not (66% vs 68%; P = .65). Conclusions CEA is a safe, effective, and durable treatment for ASCS in patients aged 80 years or more, carrying an insignificant perioperative stroke/death risk. CEA associated with BMT seems preferable to BMT alone in preventing the risk of ipsilateral ischemic events, without translating into a longer survival.

Objective The role of gender on the outcome of infrainguinal arterial revascularization (IAR) for peripheral arterial occlusive disease remains uncertain. This study analyzed the outcome of IARs ...performed over 15 years, stratifying the results by sex. Methods Details of consecutive patients undergoing primary IAR for peripheral arterial occlusive disease from 1995 to 2009 at our institution were prospectively stored in a vascular registry. Demographics, risk factors, indications for surgery, inflow sources, outflow target vessels, types of conduit, and adverse outcomes were analyzed. Postoperative surveillance included clinical examination supplemented with duplex scans and ankle-brachial index measurements in all patients at discharge, 30 days, 6 months, and every 6 months thereafter. End points of the study, ie, patency, limb salvage, and survival rates, were assessed using Kaplan-Meier life-table analysis. The χ2 or Fisher exact, Student t , and log-rank tests were used to establish statistical significance. Results Our sample consisted of 1459 IARs performed in 1333 patients, comprising 496 women (37.2%; 531 IARs), who were a mean 3 years older than the men (74 vs 71 years; P < .001) and had a higher incidence of diabetes mellitus (52% vs 46%; P = .03) and surgery for limb salvage (91% vs 87%; P = .02). An autogenous vein conduit (great or small saphenous, or both, spliced, arm, or composite veins) was used in 87% of the IARs. No deaths occurred perioperatively (30 days). The major and minor complication rates were comparable between men and women. At 10 years, the primary patency rate was 47% in women vs 49% in men ( P = .67), the assisted primary patency rate was, respectively, 53% vs 50% ( P = .69), the secondary patency rate was 61% vs 61% ( P = .66), limb salvage rate was 93% vs 91% ( P = .54), and survival rate was 43% vs 49% ( P = .65). Stratifying by type of conduit revealed no differences in patency or limb salvage rates. Conclusions Despite an older age and more advanced stages of disease on presentation in women, IAR performed in women can achieve patency and limb salvage rates statistically no different from those recorded in their male counterparts, supporting the conviction that sex per se does not influence the outcome of lower extremity revascularization.

Background and Purpose To evaluate rate of formation of midline abdominal wall incisional hernia (MAIH) after elective open repair of abdominal aortic aneurysm (AAA) and revascularization for ...aortoiliac occlusive disease (AOD). Methods AAA and AOD patients operated electively via a primary midline abdominal incision at our institution over a decade were entered in this prospective study. Patients who had already undergone midline laparotomy or had an MAIH after previous celiotomy were excluded. Patients were examined for MAIH 6-monthly for 2 years, then yearly. Results We included 1,065 patients who underwent aortic reconstructive surgery (412 with AAA and 653 with AOD). The follow-up (mean ± standard deviation) was 6.4 ± 3.8 years (range, 0.5–12.7). Wounds were closed with a suture length-to-wound length (SL:WL) ratio of at least 4:1 in 58% (239 of 653) of AAA patients and 66% (431 of 653) of AOD patients ( P = .01). There were 124 (11.6%) MAIHs, with an incidence of 12.4% (51 of 412) in the AAA group and 11.2% (73 of 653) in the AOD group ( P = .62), and 3 (0.4%) wound infections (all among the AOD patients), none of which resulted in MAIH. At multivariate analysis, a SL:WL ratio of <4:1 was the only independent predictor of MAIH in AAA ( P = .004) and AOD patients ( P < .001). Conclusion AAA and AOD patients had a similar incidence of MAIH, which seems related to the wound closure technique. A SL:WL ratio of at least 4:1 is recommended. Further clinical studies are required to determine possible technical and perioperative variables that may be modified to decrease the incidence of MAIH development after aortic reconstructive surgery.

Background Although aortoiliofemoral bypass grafting is the optimal revascularization method for patients with severe aortoiliac occlusive disease (AIOD), previous studies have documented poor ...patency rates in young adults. This study investigated whether young patients with AIOD have worse outcomes in patency, limb salvage, and long-term survival rates after reconstructive surgery than their older counterparts. Methods Patients aged ≤50 years undergoing reconstructive surgery at our institution for AIOD between 1995 and 2010 were compared with a cohort of randomly selected patients aged ≥60 years (two for each of the young patients, matched for year of operation), analyzing demographics, risk factors, indications for surgery, operative details, and outcomes. Results Among 927 consecutive patients undergoing primary surgery for AIOD, 78 (8.4%) aged ≤50 years (mean age, 48.4 years) and 156 older control patients (mean age, 71.2 years) were identified. The younger patients were mainly men (81%) and 59% had surgery for limb salvage and 41% for disabling claudication ( P = .02). Compared with older patients, they were significantly more likely to be smokers (90% vs 72%; P = .002) and had previously needed significantly more inflow procedures (28% vs 16%; P = .03). Only one death occurred perioperatively (30-day) among the control patients, and no major amputations or graft infections occurred in either group. The need for subsequent infrainguinal reconstructions was greater in the younger patients (18% vs 7%; P = .01). The primary patency rates were inferior in the younger patients at 5 years (82% and 75%) and 10 years (95% and 90%; P = .01), whereas assisted secondary patency (89% and 82% vs 96% and 91%; P = .08), secondary patency (93% and 86% vs 98% and 92%; P = .19), limb salvage (88% and 83% vs 95% and 91%; P = .13), and survival rates (87% and 76% vs 91% and 84%; P = .32) were comparable in the two groups. Conclusions This study shows that despite a higher primary graft failure rate than that in older patients, aortoiliofemoral revascularization for complex AIOD is a safe procedure for younger patients with disabling claudication or limb-threatening ischemia, providing they are willing to follow a regular protocol to complete their postoperative surveillance and to undergo graft revision as necessary.
