RESUMO
BACKGROUND AND AIMS: Identifying patients likely to have CDL is an important clinical dilemma because endoscopic retrograde cholangiopancreatography (ERCP), carries a 5-7% risk of adverse events. The purpose of this study was to compare the diagnostic test performance of the 2010 and 2019 ASGE criteria used to help risk stratify patients with suspected CDL. METHODS: Consecutive patients evaluated for possible CDL from 2013 to 2019 were identified from surgical, endoscopic, and radiologic databases at a single academic center. Inclusion criteria included all patients who underwent ERCP and/or cholecystectomy with intraoperative cholangiogram (IOC) for suspected CDL. We calculated the diagnostic test performance of criteria from both guidelines and compared their discrimination using the receiver operator curve. Univariate and multivariate analysis was used to identify the strongest component predictors. RESULTS: 1098 patients [age 57.9 ± 19.0 years, 62.8% (690) F] were included. 66.3% (728) were found to have CDL on ERCP and/or IOC. When using the 2019 guidelines, the sensitivity, specificity, PPV, NPV, and accuracy are 65.8, 78.9, 86.3, 54.1, and 70.4%, respectively. Using the 2010 guidelines, the sensitivity, specificity, PPV, NPV, and accuracy are 50.5, 78.9, 82.5, 44.8, and 60.1%, respectively. The AUC for high-risk criteria using the 2019 guidelines [0.726 (0.695, 0.758)] was greater than for the 2010 guidelines [0.647 (0.614, 0.681)]. The key difference providing the increased discrimination was the inclusion of stones on any imaging modality, which increased the sensitivity to 55.0% from 29.1%. Not including CDL on imaging or cholangitis, a dilated CBD was the strongest individual predictor of CDL on multivariate analysis (OR 3.70, CI 2.80, 4.89). CONCLUSION: Compared to 2010, the 2019 high-risk criterion improves diagnostic test performance, but still performs suboptimally. Less invasive tests, such as EUS or MRCP, should be considered in patients with suspected CDL prior to ERCP.

BACKGROUND: Straight leg raise (SLR) is a provocative maneuver that assesses esophagogastric junction (EGJ) barrier function during high-resolution manometry (HRM). We evaluated the value of SLR in symptomatic reflux patients undergoing ambulatory reflux monitoring. METHODS: Adult patients being evaluated for reflux symptoms with esophageal physiologic testing off antisecretory therapy over a 12 month period were studied. Demographics, clinical presentation, HRM studies, and reflux monitoring studies were analyzed. Intra-abdominal and intra-esophageal pressures were extracted at baseline and during SLR from HRM studies. Acid exposure time (AET) was derived from reflux monitoring studies, and EGJ morphology and tone from HRM studies. SLR pressure metrics predicting abnormal AET were evaluated. KEY RESULTS: Of 122 patients, 70 (57.4%) had ≥50% peak intra-abdominal pressure increase during SLR (58.0 ± 1.4 years, 75.7% female). Peak intra-esophageal pressure gradient between baseline and SLR predicted pathologic AET when ≥100% (AUC 0.78, sensitivity 71%, specificity 75%, P < .001), seen in 60.7% with AET > 6%, but only 23.7% with AET < 4% (P = .01). Peak intra-esophageal pressure gradient ≥100% was most discriminative in identifying abnormal acid burden in type 1 EGJ morphology (P = .005) but trended toward significance in type 2 and type 3 morphology (P = .1). Normal and abnormal EGJ contractile integral did not associate with peak intra-esophageal pressure gradient either collectively or when subdivided by EGJ morphology (P ≥ .2). CONCLUSIONS & INFERENCES: Analysis of intra-esophageal pressure gradients during SLR, a simple HRM maneuver, may augment evaluation of symptomatic GERD, and provide adjunctive evidence supporting GERD.

BACKGROUND: Straight leg raise (SLR) while supine increases intra-abdominal pressure. We hypothesized that elevations in intra-abdominal pressure would transmit into the thoracic cavity if the esophagogastric junction (EGJ) was disrupted. METHODS: Consecutive patients undergoing esophageal HRM were included if they had adequate SLR (hip flexion with knees extended for ≥ 5 seconds while supine). EGJ morphology was subtyped based on lower esophageal sphincter (LES) and crural diaphragm (CD) location (type 1: LES and CD overlap; type 2: separation of < 3 cm; type 3: separation of ≥ 3 cm). EGJ tone was assessed using EGJ contractile integral (EGJ-CI). HRM studies were analyzed according to Chicago Classification v3.0. Mean and peak intra-thoracic and abdominal pressures were measured at baseline and during SLR using on-screen software tools. Trans-EGJ gradients were compared, and pressure gradient < 1 mmHg denoted the equalization of pressures. KEY RESULTS: Of 430 patients, 248 (57.5 ± 0.9 years, 69.4% F) completed SLR. EGJ morphology was type 1 in 122 (49.2%), type 2 in 56 (22.6%) and type 3 in 40 (16.1%). In types 1 and 2 EGJ, neither the mean nor peak trans-EGJ pressure gradient changed with SLR (P ≥ .17 for each). In contrast, in type 3 EGJ, peak pressure gradient decreased significantly following SLR (3.5 ± 1.8 mmHg vs. -8.6 ± 4.8 mmHg, P = .01). More type 3 EGJ patients equalized peak (65%) pressures across EGJ compared with types 1 and 2 (27%, P < .001). CONCLUSIONS AND INFERENCES: The evaluation of intra-abdominal and intra-thoracic pressures with SLR during esophageal HRM can provide evidence of physiological disruption of the EGJ barrier.

BACKGROUND: Inappropriate sinus tachycardia (IST) is a rare clinical disorder characterized by an elevated resting heart rate and an exaggerated rate response to exercise or autonomic stress. Pharmacologic therapy and catheter ablation are considered first-line treatments for IST but can yield suboptimal relief of symptoms. The results of surgical ablation at our center were reviewed for patients with refractory IST. METHODS: Between 1987 and 2018, 18 patients underwent surgical sinoatrial (SA) node isolation for treatment-refractory IST. All 18 patients had previously failed pharmacologic therapy, and 15 patients had failed catheter ablation of the SA node. RESULTS: Ten patients underwent a median sternotomy, and 8 patients underwent a minimally invasive right thoracotomy. The SA node was isolated with the use of surgical incisions, cryoablation, or bipolar radiofrequency ablations. Sinus tachycardia was eliminated in 100% of patients in the immediate postoperative period. Long-term follow-up data were available for 17 patients, with a mean follow-up of 11.4 ± 7.9 years. At last follow-up, 100% of patients were free from recurrent symptomatic IST. More than 80% of patients were completely asymptomatic, whereas 3 patients reported occasional palpitations. Four patients were on ß-blockers, and 5 patients required subsequent pacemaker implantation. All 8 patients who underwent minimally invasive isolation were in normal sinus rhythm at last follow-up, and only 1 patient complained of palpitations. CONCLUSIONS: Surgical isolation of the SA node is a feasible treatment for IST refractory to pharmacologic therapy and catheter ablation. A minimally invasive surgical approach offers a less morbid alternative to traditional median sternotomy.

OBJECTIVE: Septal myectomy remains the criterion standard for the treatment of patients with hypertrophic obstructive cardiomyopathy refractory to medical therapy. There have been few reports of minimally invasive approaches. This study compared a minimally invasive septal myectomy performed at our institution with the traditional full-sternotomy approach. METHODS: Patients receiving a stand-alone septal myectomy were retrospectively reviewed from November 1999 to December 2016 (N = 120). Patients were stratified by surgical approach: traditional full sternotomy (n = 34) and ministernotomy (n = 86). Preoperative and perioperative variables were compared as well as follow-up symptomatic and echocardiographic outcomes. RESULTS: Both groups had a significant decrease in New York Heart Association class heart failure symptoms (P < 0.001). At a mean ± SD follow-up time of 2.0 ± 3.4 years, postoperative New York Heart Association class distribution was similar between ministernotomy and full sternotomy (P = 0.684). Follow-up resting left ventricular outflow tract gradient was also similar between ministernotomy and full sternotomy (11 mm Hg ± 15 vs 9 mm Hg ± 13, P = 0.381). Perioperatively, ministernotomy was not significantly different from full sternotomy in median cardiopulmonary bypass time (81 minutes vs 78 minutes, P = 0.101) but had a slightly longer median cross-clamp time (39 minutes vs 35 minutes, P = 0.017). Major complications were similar in the two groups. There was one 30-day mortality in the full-sternotomy group, but no in-hospital deaths. CONCLUSIONS: Septal myectomy performed using a minimally invasive approach has similar outcomes to the criterion standard operation done through a full sternotomy. It represents a feasible option for patients with hypertrophic obstructive cardiomyopathy unresponsive to medications.

OBJECTIVE: Most patients with atrial fibrillation (AF) undergoing cardiac surgery do not receive concomitant ablation. This study reviewed outcomes of patients with AF undergoing Cox-maze IV (CMIV) procedure with radiofrequency and cryoablation and coronary artery bypass grafting (CABG) at our institution. METHODS: Between the introduction of radiofrequency ablation in 2002 and 2015, 135 patients underwent left- or biatrial CMIV with CABG. Patients undergoing other cardiac procedures, except mitral valve repair, or who had emergent, reoperative, or off-pump procedures were excluded. Eighty-three patients remained in the study group after exclusion criteria were applied. Freedom from atrial tachyarrhythmias (ATAs) was ascertained using electrocardiogram, Holter monitor, or pacemaker interrogation at 1 to 5 years postoperatively. RESULTS: Operative mortality was 3%. Freedom from ATAs at 1 year in the CMIV group was 98%, with 88% off antiarrhythmia drugs. Freedom from ATAs and antiarrhythmia drugs was 70% at 5 years. CONCLUSIONS: The addition of CMIV to CABG resulted in excellent freedom from ATAs at 1 to 5 years. These patients are at increased risk for nonfatal complications compared with others undergoing concomitant surgical ablation.
