Orally administered TSM as prophylaxis before elective colorectal surgery results in a low rate of organ/space SSI but an increased rate of incisional SSI compared with intravenously administered cefuroxime and metronidazole. Thus, when considering orally administered TSM, because of environmental concerns or for economic reasons, the slightly increased infection rate has to be kept in mind.

The use of CBCT revealed a significant number of stent compressions that were not found with CA and PG. When performing endovascular procedures at the aortic bifurcation, CBCT is an excellent intra-operative evaluation method to assess the configuration of deployed stents. In this study, CBCT improved the technical results intra-operatively, which might influence the long-term patency positively.

Objectives: This study compared outcomes of an iliacbranched device (IBD) and the sandwich technique (ST) for preservation of hypogastric flow in the setting of aortoiliac aneurysm repair.Methods: Between 2010 and 2014, patients of two high-volume vascular centers referred for elective repair of abdominal aortic aneurysms (AAAs) involving iliac bifurcation or isolated common iliac artery (CIA) aneurysms underwent IBD placement or ST. Clinical and anatomic data, operative intervention, and outcomes were collected prospectively and analyzed retrospectively.Results: Thirty-seven patients underwent 40 procedures: 20 IBD and 20 ST, with placement of aortic endograft in 28 patients (70%). Technical success rate were comparable in both groups (95% vs 100%, P ¼ 1). Three external iliac artery (EIA) limbs and one internal iliac artery (IIA) stent thrombosed in the ST group. Early and late patency rates were not statistically different in the IBD group (100% and 94.7%) and in the ST group (90% and 80%; P > .05). There was no statistical difference between both groups regarding endoleaks onset (P ¼ .2). One patient suffered of transient buttock claudication after branched device IIA stent thrombosis. Reintervention rates were comparable in both groups (P ¼ .1). Both techniques permitted comparable aneurysm sac shrinkage (P ¼ .7). No rupture, colonic ischemia, or arterial access complication was noticed.Conclusions: In this retrospective study, IBD and ST provided similar outcomes for aortoiliac aneurysm treatment with hypogastric preservation. The sandwich technique represents a reliable alternative to IBD when the latter is not feasible, making patients more eligible for endovascular treatment. Further larger cohort studies are warranted to confirm these encouraging results.

LOP, FT, and CON for three FEN cases are depicted in the Fig. Overall morbidity and mortality were not different over the study period.Conclusions: There was evidence for a LCE for LOP, FT, and CON, which was strongest for three FEN cases. The shape of the learning curve was "steplike" and appeared to be driven by specific procedural improvements rather than by cumulative experience. Our findings suggest that adoption of these procedural improvements will steepen the learning curve (ie, allow rapid improvement) for surgeons performing FEVAR in the future.
