Bariatric surgery in inflammatory bowel disease: a comparative analysis of 450,000 patients.

BACKGROUND: Studies were conducted to investigate the outcomes of bariatric surgery (BS) among inflammatory bowel disease (IBD) patients. OBJECTIVES: We aimed to analyze previous literature, comparing the outcomes of BS between IBD and non-IBD patients. SETTING: Not applicable. METHODS: PubMed, Scopus, and Web of Science were searched on 25/9/2023 for comparative studies on outcomes of BS in IBD patients. RevMan Software v5.4 was used to conduct the analysis. RESULTS: Our analysis revealed an insignificant difference in the change of body mass index (BMI) at 1-year post-BS between IBD and non-IBD patients. IBD patients had a higher risk of acute renal failure, hemorrhage, and readmission following BS (RR: 2.16, 95% CI: 1.55-3, RR: 1.57, 95% CI: 1.22-2.04, RR: 1.56, 95% CI: 1.17-2.08, respectively). No significant difference was observed between both groups regarding wounds, leak/intra-abdominal infection, thromboembolic complications, and bowel obstruction. A higher incidence of postoperative complications was seen among IBD patients undergoing RYGB compared with SG (RR: 2.21, 95% CI: 1.43-3.41). There was a significant decline in steroid use following BS in IBD patients (RR: .67, 95% CI: .53-.84). Comparison between UC and Crohn's disease (CD) revealed insignificant differences in treatment escalation or de-escalation. Both IBD and non-IBD patients had similar lengths of hospitalization. CONCLUSIONS: BS is equally effective in IBD and non-IBD patients in terms of weight loss at 1-year follow-up. Nevertheless, IBD patients are at a higher risk of postoperative complications, micronutrient deficiency, and readmission. Both UC and CD reported a decline in steroid use following surgery without a preferential advantage to a particular IBD sub-type.

The Development of Totally Percutaneous Aortic Arch Repair With Inner-Branch Endografts: Experience From 2 Centers.

OBJECTIVE: The main objective of this study is to present the experience of 2 centers undertaking total percutaneous aortic arch-branched graft endovascular repair using combination of femoral and axillary routes. The report summarizes the procedural steps, outcomes achieved, and the benefits of this approach, which eliminates the need for direct open surgical exposure of the carotid, subclavian, or axillary arteries, thereby reducing the unnecessary associated surgical risks. METHODS: Retrospectively collected data of 18 consecutive patients (15M:3F) undergoing aortic arch endovascular repair using a branched device between February 2021 and June 2022 at 2 aortic units. Six patients were treated for a residual aortic arch aneurysm following previous type A dissection with size range of (58-67 mm in diameter), 10 were treated for saccular or fusiform degenerative atheromatous aneurysm with size range of (51.5-80 mm in diameter), and 2 were treated for penetrating aortic ulcer (PAU) with size range of (50-55 mm). Technical success was defined as completion of the procedure and satisfactory placement of the bridging stent grafts (BSGs) in the supra-aortic vessels percutaneously including the brachiocephalic trunk (BCT), left common carotid artery (LCCA), and left subclavian artery (LSA) without the need for carotid, subclavian, or axillary cut down. The primary technical success was examined as primary outcome well as any other related complications and reinterventions as secondary outcomes. RESULTS: The primary technical success with our alternative approach was achieved in all 18 cases. There was one access site complication (groin haematoma), which was managed conservatively. There was no incidence of death, stroke, or cases of paraplegia. No other immediate complications were noted. Postoperative imaging confirmed supra-aortic branch patency, with satisfactory position of the BSGs and immediate aneurysm exclusion except in 4 patients who had type 1C endoleak (Innominate: 2, LSA 2) detected on the first postoperative scan. Three of them were treated with relining/extension, and 1 spontaneously resolved after 6 weeks. CONCLUSIONS: Total percutaneous aortic arch repair with antegrade and retrograde inner-branch endografts can be performed with promising early results. Dedicated steerable sheaths and appropriate BSG would optimize the percutaneous approach for aortic arch endovascular repairs. CLINICAL IMPACT: This article provides an alternative and innovative approach to improve the minimally invasive techniques in the endovascular treatment of the aortic arch conditions.

A prospective multicentre study evaluating the outcomes of the abdominal wall dehiscence repair using posterior component separation with transversus abdominis muscle release reinforced by a retro-muscular mesh: filling a step.

BACKGROUND: This study aimed to evaluate the results of posterior component separation (CS) and transversus abdominis muscle release (TAR) with retro-muscular mesh reinforcement in patients with primary abdominal wall dehiscence (AWD). The secondary aims were to detect the incidence of postoperative surgical site occurrence and risk factors of incisional hernia (IH) development following AWD repair with posterior CS with TAR reinforced by retromuscular mesh. METHODS: Between June 2014 and April 2018, 202 patients with grade IA primary AWD (Björck's first classification) following midline laparotomies were treated using posterior CS with TAR release reinforced by a retro-muscular mesh in a prospective multicenter cohort study. RESULTS: The mean age was 42 ± 10 years, with female predominance (59.9%). The mean time from index surgery (midline laparotomy) to primary AWD was 7 ± 3 days. The mean vertical length of primary AWD was 16 ± 2 cm. The median time from primary AWD occurrence to posterior CS + TAR surgery was 3 ± 1 days. The mean operative time of posterior CS + TAR was 95 ± 12 min. No recurrent AWD occurred. Surgical site infections (SSI), seroma, hematoma, IH, and infected mesh occurred in 7.9%, 12.4%, 2%, 8.9%, and 3%, respectively. Mortality was reported in 2.5%. Old age, male gender, smoking, albumin level < 3.5 gm%, time from AWD to posterior CS + TAR surgery, SSI, ileus, and infected mesh were significantly higher in IH. IH rate was 0.5% and 8.9% at two and three years, respectively. In multivariate logistic regression analyses, the predictors of IH were time from AWD till posterior CS + TAR surgical intervention, ileus, SSI, and infected mesh. CONCLUSION: Posterior CS with TAR reinforced by retro-muscular mesh insertion resulted in no AWD recurrence, low IH rates, and low mortality of 2.5%. Trial registration Clinical trial: NCT05278117.
