Safety and Effectiveness of Debulking for the Treatment of Infrainguinal Peripheral Artery Disease. Data From the Recording Courses of vascular Diseases Registry in 2910 Patients.

We investigated the safety and efficacy of debulking infrainguinal lesions in patients with peripheral artery disease (PAD) undergoing endovascular revascularization (EVR) as part of the RECording Courses of vascular Diseases (RECCORD) registry. Patient and lesion specific characteristics, including the lesion complexity score (LCS) were analyzed. The primary endpoint encompassed: (i) clinical improvement in Rutherford categories, (ii) index limb re-interventions, and (iii) major amputations during follow-up. The secondary endpoint included the need for bail-out stenting. Overall, 2910 patients were analyzed; 2552 without and 358 with debulking-assisted EVR. Patients were 72 (interquartile range (IQR) = 15) years old and 1027 (35.3%) had diabetes. Overall complication rates were similarly low in the debulking vs the non-debulking group (4.7 vs 3.2%, P = .18). However, peripheral embolizations rates were low but more frequent with debulking vs. non-debulking procedures (3.9 vs 1.1%, P < .001). After adjustment for clinical and lesion-specific parameters, including LCS, no differences were noted for the primary endpoint (odds ration (OR) = 0.99, 95%CI = 0.69-1.41, P = .94). Bail-out stenting was less frequently performed in patients with debulking-assisted EVR (OR = 0.5, 95%CI = 0.38-0.65, P < .0001). Debulking-assisted EVR is currently used in ∼12% of EVR with infrainguinal lesions and is associated with lower bail-out stent rates but higher peripheral embolization rates; no differences were found regarding index limb re-intervention and amputation rates.

Long-Term Outcomes of Individualized Repair in Patients with Supravalvular Aortic Stenosis.

Various surgical techniques have been introduced to treat supravalvular aortic stenosis (SVAS). However, there is no consensus on the optimal approach. This study aimed to analyze the outcomes of surgical treatment of SVAS and determine the optimal strategy. The Kaplan-Meier curve was used to demonstrate the survival estimates. The Cox proportional hazard model was used to identify risk factors for residual aortic stenosis and residual stenosis-related reintervention. From December 2008 to December 2023, 98 patients with SVAS undergoing surgical repair in our institution were included [McGoon group, n = 62; Doty group, n = 36]. There were 2 in-hospital deaths and 1 late death. The survival rates at 1, 5, and 15years were 98.0%, 96.7%, and 96.7%, respectively in the whole cohort. Residual aortic stenosis occurred in 18 patients. Multivariable analysis showed that preoperative gradient ≥ 90mmHg (P = 0.002) and Williams syndrome (P = 0.002) were incremental risk factors for residual aortic stenosis, but surgical technique (P = 0.579) was not a risk factor for residual aortic stenosis. In the McGoon group, patients with diffuse type had worse freedom from residual aortic stenosis than patients with discrete type (P = 0.007). However, in the Doty group, patients with diffuse type had comparable freedom from residual aortic stenosis to patients with discrete type (P = 0.911). Residual stenosis-related reintervention occurred in 15 patients. Fifteen patients all underwent residual aortic stenosis-related reintervention. Of 15 patients, 6 patients also underwent residual pulmonary stenosis-related reintervention. On multivariate analysis, Williams syndrome (P < 0.001), preoperative sinotubular junction (STJ) z-score < - 3.5 (P = 0.051), and Doty repair (P = 0.033) were found to be independent risk factors associated with residual stenosis-related reintervention. In the whole cohort, freedom from residual stenosis-related reintervention at 1, 5, and 15years were 97.8%, 89.3% and 76.1%, respectively. Surgical repair of SVAS can be safely achieved using different techniques, with similar long-term mortality. Compared with McGoon repair, Doty repair was significantly associated with decreased residual aortic stenosis rates in patients with diffuse-type SVAS. Patients with preoperative gradient ≥ 90mmHg or Williams syndrome are more prone to residual aortic stenosis. Surgical technique was not associated with residual aortic stenosis rates. Williams syndrome, preoperative STJ z-score < - 3.5, and Doty repair are associated with higher residual stenosis-related reintervention rates.

Outcomes of endoscopic ultrasound-guided gallbladder drainage: A multicenter study from India (with video).

Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) offers a safe and minimally invasive alternative for percutaneous cholecystostomy (PCC) in acute cholecystitis patients with high-surgical risk. Additionally, EUS-GBD serves as a rescue biliary drainage in malignant distal biliary obstruction. Despite its widespread application, data within the Indian context remains sparse. This study aims to report the outcomes of EUS-GBD through the first multi-center study from India. We retrospectively analyzed patients undergoing EUS-GBD at six tertiary care centers of India from March 2022 to November 2023. EUS-GBD was performed by free hand or over-the-guidewire technique with lumen-apposing metal stent (LAMS) or large caliber metal stent (LCMS). The primary outcome was technical success (defined as successful deployment of stent between gallbladder and stomach/duodenal lumen). The secondary outcomes were clinical success (defined as resolution of symptoms of acute cholecystitis and more than > 50% reduction in bilirubin level within two weeks in distal biliary obstruction), adverse event rate, 30-day mortality rate and 90-day reintervention rate. Total29 patients (mean age 65.86 ± 12.91, 11 female) underwent EUS-GBD. The indication for EUS-GBD were acute cholecystitis (79.31%) and rescue biliary drainage for malignant distal biliary obstruction (20.69%). LAMS was deployed in 92.86%, predominantly by free-hand technique (78.57%). Technical and clinical success rates were 96.55% and 82.75%, respectively. Adverse events occurred in 27.59% patients, with severe adverse events (bile leak and bleeding) being uncommon (10%). Both 30-day mortality rate and 90-day reintervention rate were 13.79% in patients. Cholecysto-duodenal fistula facilitated cholecystoscopic intervention and stone removal in one patient and transgastric EUS-GBD did not hamper bilio-enteric anastomosis during Whipple surgery in two patients. EUS-GBD is a safe and effective technique for managing acute cholecystitis in high-risk patients and for biliary drainage in cases with malignant distal biliary obstruction.

Endoscopic ultrasound-guided versus surgical pancreatic duct drainage after failed endoscopic retrograde pancreatography: a pilot comparative study.

Endoscopic ultrasound-guided pancreatic duct (PD) drainage (EUS-PDD) is being increasingly performed as an alternative method to surgical drainage to achieve PD decompression after failed endoscopic retrograde pancreatography (ERP). However, no directly study has compared EUS-PDD with surgical PD drainage after failed ERP in patients with chronic pancreatitis. Consecutive patients who underwent EUS-PDD or longitudinal pancreaticojejunostomy after failed ERP were retrospectively identified from our endoscopy and medical information systems. The primary end point was the Izbicki pain score. The secondary end points were pain relief at the end of follow-up, procedure outcomes, adverse events, readmission, and reintervention. A total of 21 patients (11 EUS-PDD, 10 surgical drainages) were analyzed. There were no significant differences in mean Izbicki pain score (EUS-PDD, 13.6 ± 10.1 vs. surgical drainage 10.7 ± 7.9, p = 0.483) or complete/partial pain relief (60%/30% vs. 70%/30%, p = 0.752) at the end of follow-up of the two groups. The rates of overall adverse events (27.3% vs. 30.0%, p = 0.893) and readmission (63.6% vs. 40.0%, p = 0.290) were similar in the two treatment groups, while patients in EUS-PDD group required more reinterventions (45.5% vs. 0%, p = 0.039) compared with patients in the surgery group. EUS-PDD showed comparable pain relief and safety to surgical PD drainage after failed ERP, with a higher rate of reintervention. The selection of EUS-PDD or surgical drainage may be appropriate based on an individualized strategy.

Outcomes of advanced EVAR versus open surgery in the management of complex abdominal aortic aneurysm repair: A systematic review and meta-analysis.

Open surgery is still acknowledged as the gold standard for complex abdominal aortic aneurysm (c-AAA). Recently, advanced-endovascular aortic aneurysm repair (EVAR) for c-AAA has been developed, but its effectiveness compared to open surgery is still unclear. A systematic search was performed on the MEDLINE through PubMed and ScienceDirect databases. The search was aimed to investigate outcomes of both fenestrated- and chimney-EVAR (consider as advanced EVAR) compared to open surgery in c-AAA. Outcomes included postoperative complications, 30-day mortality, long-term mortality, and reintervention rate. Data were collected using the Mantel-Haenszel fixed effects model with relative risk (RR) as the effect size with 95% confidence interval (CI). A total of 25 studies (n = 12,845 patients) were included in our study. The results demonstrated that advanced-EVAR correlated with diminished postoperative complications (RR 0.53; 95% CI 0.49-0.57; p < 0.001) compared to open surgery. Advanced-EVAR was associated with lower 30-day mortality compared to open surgery (RR 0.66; 95% CI 0.53-0.82; p < 0.001). Subgroup analysis revealed that fenestrated-EVAR resulted in superior outcomes (p < 0.001), whereas the chimney-EVAR subgroup did not show significant differences (p = 0.79), compared to open surgery in terms of 30-day mortality. Unfortunately, advanced-EVAR was associated with a higher long-term mortality rate (RR 1.46; 95% CI 1.20-1.78; p < 0.001) and a higher reintervention rate (RR 1.26; 95% CI 1.01-1.59; p = 0.04) compared to open surgery. Advanced EVAR, especially fenestrated-EVAR, presented better short-term outcomes compared to open surgery; however, it failed to demonstrate superiority over open surgery in improving long-term outcomes.

Systematic review of long-term effectiveness of endoscopic gastrojejunostomy in patients presenting with gastric outlet obstruction from periampullary malignancies.

Recently, endoscopic ultrasound-guided (EUS) gastrojejunostomy (GJ) has emerged as an alternative option to surgical palliation and endoscopic duodenal stenting for malignant gastric outlet obstruction (GOO). Although early success rates are commonly reported with the technique, there is a paucity of data regarding the long-term efficacy of this approach. In this study, we investigated long-term outcomes in patients that underwent EUS-guided GJ for palliation of periampullary malignancies. From a total of 192 studies that were reviewed, 6 studies with a follow-up time frame of a minimum of 5months were analyzed, totaling 238 patients. Outcome variables included technical success rate, clinical success rate, adverse events, symptom recurrence, and re-intervention rates. The cohort of 238 patients had a technical success rate of 93.7% and a clinical success rate of 92.9%. A total of 25 patients (10.5%) experienced adverse events associated with EUS-GJ. A total of 14 patients (5.9%) experienced recurrence of GOO symptoms within 5months. A total of 14 patients (5.9%) underwent re-intervention with the first 5months. This systematic review shows that data are scarce regarding long-term effectiveness of EUS-guided GJ. Even though early success rates have been reported, further studies are needed to focus on long-term efficacy of this approach. Until such studies become available, surgical palliation should continue to be the treatment of choice for patients with malignant GOO with a prolonged life expectancy.

Endovascular Treatment of Abdominal Aortic Aneurysm: Impact of Diabetes on Endoleaks and Reintervention.

Background: Diabetes has a protective effect on abdominal aortic aneurysms (AAAs); however, there are contrasting reports on the impact of diabetes on endovascular aortic repair (EVAR) outcomes, endoleaks (ELs) being the major negative outcome. The present study characterizes ELs and their outcomes in AAA patients, diabetic or not. Methods: This single-center, retrospective, comparative study was carried out on 324 AAA patients who underwent elective EVARs between 2007 and 2016 at the University Hospital of Liège (Belgium). The primary endpoint was the incidence and effect of ELs on the evolution of the aneurysmal sac; the secondary endpoints were surgical reintervention and mortality rate. Diabetic and non-diabetic patients were compared with respect to various risk factors by logistic regression, while a Cox regression was used to analyze survival. Results: In AAA patients meeting the inclusion criteria (n = 248), 23% were diabetic. EL incidence was comparable (p = 0.74) in diabetic (38.7%) vs. non-diabetic (43.9%) patients. EL risk factors were age (HR = 1.04, p = 0.014) and fibrate intake (HR = 3.12, p = 0.043). A significant association was observed between ELs and aneurysm sac enlargement (p < 0.001), regardless of group (p = 0.46). Aneurysm sac regression per month for non-diabetic patients was -0.24 ± 0.013, while for diabetics it was -0.18 ± 0.027 (p = 0.059). Dyslipidemia (HR = 3.01, p = 0.0060) and sulfonylureas (HR = 8.43, p = 0.043) were associated with shorter EL duration, while diabetes (HR = 0.080, p = 0.038) and beta blockers (HR = 0.46, p = 0.036) were associated with longer EL duration. The likelihood of reoperation decreased with more recent surgery (OR = 0.90, p = 0.040), regardless of diabetic status. All-cause mortality was higher for the non-diabetic group (45.5% vs. 26.3%, p = 0.0096). Conclusions: Endoleak occurrence is a known risk factor for sac expansion. In diabetic patients, endoleaks lasted longer, and regression of the aneurysm sac tended to be slower. The number and type of reintervention was not related to the diabetic status of AAA patients, but overall survival was higher in patients with diabetes.

Correlation Between Calcium Scoring and Abdominal Aortic Aneurysm Endovascular Repair Outcomes.

Endovascular aneurysm repair, though minimally invasive and has the benefit of relatively low perioperative complication rates, it is associated with significant long term reintervention rates related to endoleaks. Several variables have been studied to predict the outcomes of endovascular aneurysm repair, 1 of which is the calcium burden of the vasculature. This prompted us to study the association between calcium burden measured by the standardized Agatston scoring system and the outcomes of Endovascular aneurysm repair. This is a retrospective study of patients who underwent Endovascular aneurysm repair from 2008 to 2020 at our institution and who had a non-contrast computerized tomography scan preoperatively, accounting for 87 patients. The calcium burden of the vasculature was measured by the Agatston scoring system allowing for better reproducibility, and the outcome variables included mortality and endoleaks. Patients with higher median total calcium scores (≥12966.9) had significantly lesser survival (79.8% vs 52.3% (P = .002) at five years compared to patients with lower median total calcium score (<12966.9). Also, patients with type 2 endoleaks had higher calcium scores in above the aneurysm level ((1591.2 vs 688.2), P = .05)) compared to patients with no type 2 endoleaks. Calcium score assigned using a standardized Agatston scoring system can be used as a predictor of mortality risk assisting in deciding the treatment of choice for patients.

MEDIAL MALLEOLUS: OPERATIVE OR NONOPERATIVE (MOON). A RANDOMIZED CLINICAL TRIAL OF OPERATIVE VERSUS NONOPERATIVE MANAGEMENT OF ASSOCIATED MEDIAL MALLEOLUS FRACTURES IN UNSTABLE ANKLE FRACTURE DISLOCATIONS

IntroductionUnstable ankle fractures are routinely managed operatively. Due to soft-tissue and implant related complications, there has been recent literature reporting on the non-operative management of well-reduced medial malleolus fractures following fibular stabilisation, but with limited evidence supporting routine application. This trial assessed the superiority of internal fixation of well-reduced (displacement ≤2mm) medial malleolus fractures compared with non-fixation following fibular stabilisation.Methods and participantsSuperiority, pragmatic, parallel, prospective randomised clinical trial conducted over a four year period. A total of 154 adult patients with a bi- or trimalleolar fractures were recruited from a single centre. Open injuries and vertical medial malleolar fractures were excluded. Following fibular stabilisation, patients were randomised intra-operatively on a 1:1 basis to fixation or non-fixation after satisfactory fluoroscopic fracture reduction was confirmed. The primary outcome was the Olerud Molander Ankle Score (OMAS) at one-year post-randomisation. Complications and radiographic outcomes were documented over the follow-up period.ResultsAmong 154 participants (mean age, 56.5 years; 119 women [77%]), 144 [94%] completed the trial. At one-year the median OMAS was 80 (IQR, 60–90) in the fixation group compared with 72.5 (IQR, 55–90) in the non-fixation group (p=0.17). Complication rates were comparable. Significantly more patients in the non-fixation group developed a radiographic non-union (20% vs 0%; p&lt;0.001), with the majority (n=8/13) clinically asymptomatic and one patient required surgical re-intervention for this. Fracture type and reduction quality appeared to influence fracture union and patient outcome.ConclusionsIn this randomised clinical trial comparing internal fixation of well-reduced medial malleolus fractures with non-fixation, following fibular stabilisation, fixation was not superior according to the primary outcome. However, 1 in 5 patients following non-fixation developed a radiographic non-union and whilst the re-intervention rate to manage this was low, the future implications require surveillance. These results may support selective non-fixation of anatomically reduced medial malleolus fractures.

Allogenic Stem Cells in Anal Fistulas of Crohn's Disease: From Promising Premises to Real Life Experience.

Allogenic adipocyte stem cells represent an unprecedented opportunity for regenerative therapy to treat Crohn anal fistulas. Apart from the results of one 8-year-old trial, scientific evidence remains scarce. Data from consecutive patients treated with darvadstrocel for Crohn anal fistulas were reviewed at 6 first tertiary reference centers. The judgment criteria combined asymptomatic status plus clinical occlusion of the fistula tract and MRI-confirmed healing of the tract (no inflammation and/or disappearance of the tract). Both clinical and MRI-confirmed healing of the tract defined a deep remission. Clinical remission was defined by an absence of complaint, occlusion of all external openings, and no fistula discharge. A total of 116 patients were extracted (median follow-up after cell stem injection: 11 [6-14] months). No severe adverse events were reported after surgery except for subsequent anal surgery in 29 (25%) patients. Fifty-one (44%) patients had clinical remission defined by the absence of complaints, the occlusion of all external openings, and the presence of no fistula discharge. Deep remission was observed in 23 (29%) patients. Patients with clinical remission more often received combined therapy (immunosuppressant antitumor necrosis factors) than those with no improvement (31 of 51 [61%] vs 23 of 65 [35%]; P = .007). Regression analysis showed that high fistulas (odds ratio, 3.8 [1.1-12.5]; P = .03) and younger age (<38 years, odds ratio, 2.3 [1.0-58;4]; P = .02) were associated with a better outcome. Allogeneic stem cell treatment of Crohn's anal fistulas results in complete remission in less than half of patients, with a significant reintervention rate.

Long-term outcomes of total arch replacement with bilateral antegrade cerebral perfusion using the "arch first" approach.

To report outcomes of total arch replacement (TAR) with hypothermic circulatory arrest and bilateral antegrade cerebral perfusion (bACP) using an "arch first" approach for acute Type A aortic dissection (ATAAD). The "arch first" approach involved revascularization of the aortic arch branch vessels with uninterrupted ACP, before lower body circulatory arrest, while the patient was cooling. This was an observational study of aortic surgeries from 2010 to 2021. All patients who underwent TAR with bACP for ATAAD were included. Short-term and long-term outcomes were reported utilizing descriptive statistics and Kaplan-Meier survival estimation. A total of 215 patients were identified who underwent TAR + bACP for ATAAD. Age was 59.0 [49.0-67.0] years and 35.3% were female. 73 patients (34.0%) underwent a concomitant aortic root replacement, 188 (87.4%) had aortic cannulation, circulatory arrest time was 37.0 [26.0-52.0] minutes, and nadir temperature was 20.8 [19.4-22.5] degrees Celsius. 35 patients (16.3%) had operative mortality (STS definition), 17 (7.9%) had a new stroke, 79 (36.7%) had prolonged mechanical ventilation (>24h), 35 (16.3%) had acute renal failure (by RIFLE criteria), and 128 (59.5%) had blood product transfusions. One-year survival was 77.1%, while 5-years survival was 67.1%. During follow-up, there were 23 (10.7%) reinterventions involving the descending thoracic aorta - either thoracic endovascular aortic repair or open thoracoabdominal aortic replacement. Among patients with ATAAD, short-term postoperative outcomes after TAR + bACP using the "arch first" approach are acceptable. Moreover, this operative strategy may furnish long-term durability, with a reasonably low reintervention rate and satisfactory overall survival.

Standardization of the Norwood Procedure Improves Outcomes in a Medium-Sized Volume Center.

The Norwood operation has become common practice to palliate patients with hypoplastic left heart structures. Surgical technique and postoperative care have improved; yet, there remains significant attrition prior to stage II palliation. The objective of this study is to report outcomes before and after standardizing our approach to the Norwood operation. Patients who underwent the Norwood operation at Children's of Alabama were identified, those who underwent hybrid palliation operations were excluded. Pre- (2015-2020) and post- (2020-January 2023) standardization groups were compared and outcomes analyzed. Ninety-one patients were included (pre-standardization 44 (48.3%) and 47 (51.7%) post-standardization). There were no differences in baseline and intraoperative characteristics at Norwood between the pre- and post-standardization groups. Compared with pre-standardization, post-standardization was associated with decreased time to extubation (OR 0.87, 95%CI 0.79-0.96), inotrope duration (OR 0.92, 95%CI 0.86-0.98) and hospital length of stay (OR 0.98, 95%CI 0.96-0.99). There was a trend toward decreased cardiac arrest, reintervention rates, and interstage mortality for the post-standardization group. A standardized approach to complex neonatal cardiac operations such as the Norwood procedure may improve morbidity and decrease hospital resource utilization. We recommend establishing protocols at an institutional level to optimize outcomes in such high-risk patient populations.

Performance of restorations in primary molars over a seven-year period

ObjectiveThe aim of this study was to evaluate the use and reintervention rate of fillings compared to preformed metal crowns in the everyday clinical practice of German dentists. MethodsIn this retrospective, longitudinal analysis, fee codes from the Kassenzahnärztliche Vereinigung Westfalen-Lippe for restorations placed in primary molars between 2012 and 2015 in children until 7 years of age followed for a 7-year period (latest until December 2022) were filtered and analyzed with the Fine and Gray competing risk regression and Cox proportional hazards regression to calculate the risk of reintervention divided into the main outcomes “Successful”, “Minor Failure/Repair” and “Major Failure/Endodontic Treatment/Extraction”. 367,139 primary molars (one-surface fillings: n = 117,721; two-surface fillings n = 198,815; three-surface fillings n = 36,695; more than three-surface fillings n = 8,267 and preformed metal crowns n = 5,641 were included in this study. ResultsTeeth treated with preformed crowns needed significantly less re-interventions. Subdistribution hazard ratio for minor events was 0.117 (95 %-CI: 0.097 to 0.141) and hazard ratio of major events (HR=0.786; 95 %-CI: 0.695 to 0.890) when compared to one-surface fillings in multivariable adjusted analysis. Within 7-year follow-up preformed crowns required less repairs (80.6 % success rate, minor failure 4.4 %, major failure 16.3 %) than the teeth treated with composite fillings (46.2 %–52.6 % success rate, minor failure 27.0 %–39.5 %, major failure 15.5 %–28.4 %, p < 0.001). ConclusionWithin the German healthcare system fillings are the first choice for treating primary molars despite considerably higher reintervention rates. This encourages a discussion on the indication of fillings and the more durable preformed metal crowns to reduce unnecessary reintervention in young children. Clinical significanceThis study gives an unprecedented insight into the German healthcare system regarding the reintervention rates of the most relevant treatment techniques for caries in primary molars.

Challenges in prompt identification and surgical correction of Marfan Syndrome aortic disease in a middle-income country: a case series study

BackgroundMarfan Syndrome is an autosomal dominant disease caused by pathogenetic variants in the FBN1 gene. The progressive dilatation of the aorta and the potential risk of acute aortic syndromes influence the prognosis of these patients. We aim to describe population characteristics, long-term survival, and re-intervention patterns in patients who underwent aortic surgery with a previously confirmed clinical diagnosis of Marfan Syndrome in a middle-income country.MethodsA retrospective single-center case series study was conducted. All Marfan Syndrome patients who underwent aortic procedures from 2004 until 2021 were included. Qualitative variables were frequency-presented, while quantitative ones adopted mean ± standard deviation. A subgroup analysis between elective and emergent procedures was conducted. Kaplan-Meier plots depicted cumulative survival and re-intervention-free. Control appointments and government data tracked out-of-hospital mortality.ResultsFifty patients were identified. The mean age was 38.79 ± 14.41 years, with a male-to-female ratio of 2:1. Common comorbidities included aortic valve regurgitation (66%) and hypertension (50%). Aortic aneurysms were observed in 64% without dissection and 36% with dissection. Surgical procedures comprised elective (52%) and emergent cases (48%). The most common surgery performed was the David procedure (64%), and the Bentall procedure (14%). The in-hospital mortality rate was 4%. Complications included stroke (10%), and acute kidney injury (6%). The average follow-up was 8.88 ± 5.78 years. Survival rates at 5, 10, and 15 years were 89%, 73%, and 68%, respectively. Reintervention rates at 1, 2.5, and 5 years were 10%, 14%, and 17%, respectively. The emergent subgroup was younger (37.58 ± 14.49 years), had the largest number of Stanford A aortic dissections, presented hemodynamic instability (41.67%), and had a higher requirement of reinterventions in the first 5 years of follow-up (p = 0.030).ConclusionIn our study, surveillance programs played a pivotal role in sustaining high survival rates and identifying re-intervention requirements. However, challenges persist, as 48% of the patients required emergent surgery. Despite not affecting survival rates, a greater requirement for reinterventions was observed, emphasizing the necessity of timely diagnosis. Enhanced educational initiatives for healthcare providers and increased patient involvement in follow-up programs are imperative to address these concerns.

Efficacy of endoscopic ultrasound-guided gastroenterostomy using self-expandable metallic stent for afferent loop syndrome: A single-center retrospective study.

Endoscopic ultrasound-guided gastroenterostomy is a procedure used to connect the stomach and dilated afferent loop using a stent under endoscopic ultrasound for afferent loop syndrome. However, the actual efficacy and safety of this procedure remain unclear. Therefore, this retrospective study aimed to evaluate the efficacy and safety of endoscopic ultrasound-guided gastroenterostomy using a laser-cut-type fully covered self-expandable metallic stent and an anchoring plastic stent for afferent loop syndrome. Technical and clinical success rates, adverse events, recurrent intestinal obstruction rates, time to recurrent intestinal obstruction, and technical and clinical success rates of re-intervention were evaluated in intended patients who underwent endoscopic ultrasound-guided gastroenterostomy for afferent loop syndrome from October 2018 to August 2022. In 25 intended patients with afferent loop syndrome who intended endoscopic ultrasound-guided gastroenterostomy, the technical success rate was 100% (25/25), whereas the clinical success rate was 96% (24/25). Two patients experienced grade≥3 early adverse events, including one with intra-abdominal abscess and one with hypotension. Both events were attributed to intestinal fluid leakage. No late adverse events were observed. The recurrent intestinal obstruction rate was 32% (8/25), and the median time to recurrent intestinal obstruction was 6.5months (95% confidence interval: 2.8-not available). The technical and clinical success rates of re-intervention were both 100% (8/8). Endoscopic ultrasound-guided gastroenterostomy using a fully covered self-expandable metallic stent and an anchoring plastic stent is effective and safe as a treatment procedure for afferent loop syndrome.

Complications after volar plate synthesis for distal radius fractures.

Distal radius fractures (DRFs) represent up to 18% of all fractures in the elderly population, yet studies on the rate of complications following surgery are lacking in the literature. This systematic review aimed to quantify the rate of complications and reinterventions in patients treated with volar plate for distal radius fractures, and analyze if there was any predisposing factor. A comprehensive literature search was performed on three databases up to January 2023, following PRISMA guidelines. Studies describing volar plate complications and hardware removal were included. A systematic review was performed on complications and rate of reintervention. Assessment of risk of bias and quality of evidence was performed with the 'Down and Black's Checklist for measuring quality'. About112 studies including 17 288 patients were included. The number of complications was 2434 in 2335 patients; the most frequent was carpal tunnel syndrome (CTS), representing 14.3% of all complications. About 104 studies reported the number of reinterventions, being 1880 with a reintervention rate of 8.5%. About 84 studies reported the reason of reintervention; the most common were patient's will (3.0%), pain (1.1%), CTS (1.2%), and device failure (1.1%). The complication rate after DRFs is 13.5%, with the main complication being CTS (14.3%), followed by pain and tendinopathy. The reintervention rate is 8.5%, mainly due to the patient's willingness, and all these patients had plate removal. Correct positioning of the plate and correct information to the patient before surgery can reduce the number of hardware removal, thereby reducing costs and the risk of complications associated with VLP for distal radius fractures.

Practice patterns in utilization of atherectomy and embolic protection devices in inpatient and outpatient treatment settings

ObjectiveThe frequency of atherectomy in lower extremity arterial disease has increased substantially over the past several years, specifically in the office-based laboratory (OBL) setting, yet the efficacy compared with other interventions and the consequences of distal embolization remain unknown. Embolic protection devices (EPDs) have been used at varying rates depending on physician and practice setting. Previous studies have described lesion characteristics to consider when weighing the benefits and drawbacks associated with device use. Our study focuses on the use of atherectomy and EPDs in femoropopliteal arterial disease to better characterize resource use trends and postoperative outcomes in the inpatient and OBL interventional settings. MethodsWe conducted a retrospective analysis on endovascular interventions performed for femoral-popliteal occlusive disease that were entered into the Vascular Quality Initiative data registry between 2017 and 2021. A one:one greedy match, adjusted analysis based on inpatient or OBL location of procedure was used to compare the groups. Hierarchical logistical regression with selective use of principal component analysis was used to further explore the differences in EPD use and immediate postoperative outcomes. A proportional hazard model was used to demonstrate differences in reintervention rates up to 2 years postoperatively between patients who underwent atherectomy in the inpatient vs OBL treatment setting. Results2849 matched pairs were inlcuded in the final analysis. In our cohort, there was 22% EPD use overall, 40% in the hospital setting and 4.4% in the OBL setting (P < .001). Among the patients with available follow-up information, OBL intervention setting increased probability of reintervention by 18% at 2 years postoperatively compared with the inpatient setting; however, there was no difference associated with EPD placement and rate of reintervention. ConclusionsUse of EPDs in the OBL setting compared with the hospital setting is dramatically decreased; however, no increased incidence of postoperative complications was seen compared to procedures performed in the hospital setting when controlling for patient and lesion characteristics. Patients with available follow-up data were more likely to undergo ipsilateral reintervention between 6 months and 2 years postoperatively if atherectomy was done in the OBL setting. Dedicated studies are encouraged to ensure patient safety, effective resource allocation, and long-term efficacy of OBL atherectomy as an ever-growing number of peripheral arterial procedures are transitioned to the OBL setting.

Analysis of completion intraoperative venography during first rib resection for venous thoracic outlet syndrome

BackgroundWe evaluated the impact of completion intraoperative venography on clinical outcomes for axillosubclavian vein (AxSCV) thrombosis owing to venous thoracic outlet syndrome (vTOS). MethodsWe performed a retrospective, single-center review of all patients with vTOS treated with first rib resection (FRR) and intraoperative venography from 2011 to 2023. We reviewed intraoperative venographic films to classify findings and collected demographics, clinical and perioperative variables, and clinical outcomes. Primary end points were symptomatic relief and primary patency at 3 months and 1 year. Secondary end points were time free from symptoms, reintervention rate, perioperative complications, and mortality. ResultsFifty-one AxSCVs (49 patients; mean age, 31.3 ± 12.6 years; 52.9% female) were treated for vTOS with FRR and external venolysis followed by completion intraoperative venography with a mean follow up of 15.5 ± 13.5 months. Before FRR, 32 underwent catheter-directed thrombolysis (62.7%). Completion intraoperative venography identified 16 patients with no stenosis (group 1, 31.3%), 17 with no stenosis after angioplasty (group 2, 33.3%), 10 with residual stenosis after angioplasty (group 3, 19.7%), and 8 with complete occlusion (group 4, 15.7%). The overall symptomatic relief was 44 of 51 (86.3%) and did not differ between venographic classifications (group 1, 14 of 16; group 2, 13 of 17; group 3, 10 of 10; and group 4, 7 of 8; log-rank test, P = .5). The overall 3-month and 1-year primary patency was 42 of 43 (97.7%) and 32 of 33 (97.0%), respectively (group 1, 16 of 16 and 9 of 9; group 2, 16 of 17 and 12 of 13; group 3, 10 of 10, 5 of 5; group 4, primary patency not obtained). There was one asymptomatic rethrombosis that resolved with anticoagulation, and three patients underwent reintervention with venous angioplasty for significant symptom recurrence an average 2.89 ± 1.7 months after FRR. ConclusionsOur single-center retrospective study demonstrates that FRR with completion intraoperative venography has excellent symptomatic relief and short- and mid-term patency despite residual venous stenosis and complete occlusion. Although completion intraoperative venographic classification did not correlate with adverse outcomes, this protocol yielded excellent results and provides important clinical data for postoperative management. Our results also support a conservative approach to AxSCV occlusion identified after FRR.

Comparison of outcomes of percutaneous deep venous arterialization in multiple practice settings

ObjectiveWe compared the efficacy of percutaneous deep venous arterialization (pDVA) in patients with no-option chronic limb-threatening ischemia in the hospital vs in office-based laboratory (OBL) settings. MethodsA retrospective chart review was performed of all patients who underwent pDVA using off-the-shelf devices from January 2018 to March 2023 in a hospital and an OBL. We identified 73 eligible patients, 41 from a hospital setting (59% male; median age, 72 years; interquartile range, 18 years) and 32 from an OBL setting (59% males; 67 years; interquartile range, 16 years). All eligible patients were deemed to have no-option critical limb ischemia, had at least one patent proximal tibial artery available for the creation of an arteriovenous anastomosis, and were classified as having Rutherford classification IV or higher peripheral arterial disease. Patients were ineligible if classified as Rutherford classification III or lower, had active infection, did not have at least one appropriate venous target, and/or had rapidly progressing wounds requiring immediate major amputation. The primary outcome was major amputation-free survival (AFS). Secondary outcomes included technical success, limb salvage, survival, primary patency, reintervention rate, adverse events, and partial and complete wound healing. Outcomes were evaluated using Kaplan-Meier method, log-rank, and two-stage procedure tests. ResultsTechnical success was achieved in 70 patients (96%) with 1 hospital (2.4%) and 2 OBL (6.3%) patients lost to follow-up. Major AFS estimates at 6 months, 1 year, and 2 years were 51.4%, 40.4%, and 30.2% in the hospital group and 69.4%, 54.0%, and 49.5% in the OBL group, respectively. Partial wound healing estimates at 6 months, 1 year, and 2 years were 27.5%, 71.7%, and 81.2% in the hospital group and 62.7% at all time points in the OBL group. Complete wound healing estimates at 6 months, 1 year, and 2 years were 6.7%, 33.3%, and 33.3% in the hospital group and 5.3%, 37.7%, and 41.6% in the OBL group, respectively. There was no significant difference in major AFS (P = .13), limb salvage (P = .07), survival (P = .69), primary patency (P = .53), partial (P = .08), or complete wound healing (P = .79) between groups. Reintervention was performed in 8 hospital (20.5%) and 14 OBL (45.2%) patients. ConclusionspDVA is a feasible and safe procedure for no-option critical limb ischemia in the hospital and OBL setting without significant differences in outcomes at ≤2 years.
