ABSTRACT
Introduction: Gastric outlet obstruction (GOO) is a common complication in advanced stage upper gastrointestinal malignancies. The symptoms of severe nausea and protracted vomiting can lead to a decline in quality of life and cachexia. Symptoms of GOO can be effectively managed with either operative or nonoperative palliative interventions. In our article, we aim to compare laparoscopic gastrojejunostomy (GJ) to endoscopic stenting as palliative interventions for GOO. Methods: We retrospectively evaluated the charts of patients who underwent palliative procedure for gastric outlet obstruction. Group I included patients who underwent endoscopic stenting, and group II patients underwent Laparoscopic GJ. The groups' demographics (age, gender), length of procedure, length of stay, days to oral intake, overall survival, complications rate, and 30-day mortality rates were compared. Results: Overall, 38 patients were included in the study. Nineteen patients underwent endoscopic stenting and 19 underwent laparoscopic GJ. Comparing the groups, no significant differences were noted. Surgical time was significantly longer than the endoscopic procedures (83 minutes versus 25 minutes, P = .001). No significant differences were noted in days of oral intake initiation, overall survival and 30-day mortality rates. Five patients in the stenting group had complications (26.3%) versus none in the surgical group (P = .046). No postoperative complications were noted. Conclusion: Laparoscopic GJ is a safe and feasible treatment for GOO, demonstrating early resumption of oral intake. The relative short hospital stay, combined with an encouraging postoperative complications profile and low reintervention rate, should be kept in mind especially among patients with longer life expectancy.
ABSTRACT
INTRODUCTION: Achalasia is a disorder of esophageal motility characterized by absent relaxation of the lower esophageal sphincter and abnormal peristalsis of the esophagus during swallowing. The etiology is divided into primary idiopathic achalasia and secondary achalasia and classified into 3 subtypes based on manometric evaluation, according to the Chicago 4.0 classification. The goal of the therapy is symptomatic improvement and prevention of late complications. While there are several endoscopic therapies, the gold standard therapy is laparoscopic Heller myotomy. Since its debut in 2008, per-oral-endoscopic-myotomy (POEM) became an accepted treatment for achalasia with non-inferior short term outcomes compared to Heller myotomy. In the following review, we will explore the indications, guidelines, and controversies in the modern treatment of achalsia, focusing on the Heller myotomy versus POEM.

BACKGROUND: Since many COVID-19 publications lack consensus reviews or controls, interpretive accuracy is unclear; abdominal processes unique or infrequent during the pandemic remain unknown. The incidence and nature of CT findings accounting for abdominal complaints in COVID patients, reader agreement and overcalling will be determined. METHODS: A retrospective study was performed on COVID patients with abdominal complaints from 3/15/2020-5/31/2020 and 11/1/2020-4/15/2021 including matched controls. Reviewers blinded to initial reads interpreted abdominopelvic CT exams, with discordant cases resolved in consensus. Reader agreement was measured by Cohen's Kappa, differences between cohorts by permutation tests and factors affecting false positive/negative rates by Fisher's Exact Test and logistic regression. RESULTS: 116 first wave (average age 65 years [±15.3], 63 [54%] women) and 194 second wave COVID cases (average age 64 years [±16.3], 103 [53%] women) including 116 wave 1 and 194 wave 2 prepandemic controls were included. Concordance was lower among COVID cases than controls (Cohen's Kappa of 0.58 vs. 0.82 [p ≤ 0.001]) and among wave 1 than wave 2 cases (Cohen's Kappa of 0.45 vs. 0.66 [p = 0.052]). With true positives defined as consensus between the initial reader and study reader, false positive rates were higher among COVID cases than controls (OR = 0.42, p = 0.003) and for initial than study reader (OR = 0.36, p ≤ 0.001), but lower in wave 2 than 1 (OR = 0.5, p = 0.028). CONCLUSION: Greater reader disagreement occurred during COVID than prepandemic with no reader bias as both initial and study readers called more false positives among COVID cases than controls. More overcalling occurred during COVID with colitis and cystitis most common.

BACKGROUND & AIMS: Barrett's esophagus (BE) might recur after complete eradication of intestinal metaplasia (CEIM). We investigated factors associated with recurrence of BE after successful Radiofrequency ablation (RFA). METHODS: A longitudinal study of BE patients with dysplasia treated with RFA from 2014 to 2021 in two large referral centers. Recurrence was identified in histologic specimens. Factors associated with post-RFA recurrence were analyzed using Cox regression analysis. RESULTS: A total of 728 patients with BE were identified, 118 had underwent RFA, and 113 had sufficient follow up time. Mean age was 63.7 (±11.7) years, 73.5% were males, 59.3% had long segment of BE, and 30.1% had multifocal dysplasia. During 340.8 patient-years of follow-up, 15 patients (13.3%) had recurrence of BE, which represent an incidence rate of 4.41% per patient-year. Incidence rate of recurrence with dysplasia was 1.17% per patient-year. Multifocal dysplasia, number of RFA sessions, and endoscopic resection before RFA were associated with risk of recurrence in univariate analysis. However, in cox regression analysis only multifocal dysplasia (HR 10.99; 95% CI 2.83-22.62, p = 0.001) was associated with post-RFA recurrence. CONCLUSION: Total recurrence rates after CEIM are low, and multifocal dysplasia before the ablative therapy is significantly associated with BE recurrence after CEIM. Patients with multifocal dysplasia should be monitored rigorously after successful ablation.

BACKGROUND AND AIMS: With the development of narrow-band imaging (NBI) in the endoscopic evaluation of patients with Barrett's esophagus (BE), the role of random biopsies according to the Seattle protocol (SP) has been questioned. We aim to compare the utility of advanced imaging to SP in patients with BE. METHODS: A prospective cohort of patients with proven BE was retrospectively analyzed. All biopsies were reviewed by an expert GI pathologist. Advanced imaging was tandemly used with SP in each endoscopic procedure. RESULTS: A total of 155 out of 340 patients (45.5%) with BE were diagnosed with dysplasia during a median follow-up of 4.7 years (IQR 3.4-6.1 years) and were part of the statistical analysis. A total of 82 patients had a diagnosis of dysplasia at presentation, whereas 84 patients developed dysplasia during follow up. A total of 67 out of 82 patients with dysplasia at presentation (81.7%), and 65 out of 84 patients that were diagnosed with dysplasia during follow-up (77.4%) were diagnosed using SP. In addition, whereas all the events of EAC were diagnosed using targeted biopsies, 57.1% of the events of HGD and 86.3% of LGD were diagnosed using SP. CONCLUSION: Our findings demonstrate the significance of SP in the detection of low- and high-grade dysplasia in patients with BE. SP should remain the mainstay of endoscopic surveillance in this population.
ABSTRACT
RATIONALE AND OBJECTIVES: The COVID-19 pandemic led to the national shutdown and subsequent reopening of cancer screening programs. Our diverse inner-city lung cancer screening program serves patients in the Bronx NY, which was severely affected by COVID-19, with the highest mortality in New York State in the spring of 2020. Staffing redeployment, quarantine protocols, increased safety measures, and changes in follow up resulted. The purpose of this study is to analyze the effect of the pandemic on lung cancer screening volumes during the first year of the pandemic. METHODS AND MATERIALS: Retrospective cohort comprised of all patients enrolled in our Bronx, NY lung cancer screening program from March 2019 to March 2021 who underwent LDCT or appropriate follow-up imaging. The pre-pandemic and pandemic period were defined as 3/28/2019 to 3/21/2020 and 3/22/2020 to 3/17/2021, respectively, dichotomized by the New York State lockdown. RESULTS: 1218 exams were performed in the pre-pandemic period and 857 in the pandemic period, a 29.6% decrease. The percentage of exams performed on newly enrolled patients decreased from 32.7% to 13.8% (p < 0.001). Patients in the pre-pandemic period and pandemic period respectively had the following demographic breakdown: mean age 66.9 ± 5.9 vs 66.5 ± 6.0, women 51.9% vs 51.6%, White 20.7% vs 20.3%, Hispanic/Latino 42.0% vs 36.3%. There was no significant difference in Lung-RADS scores for pre-pandemic and pandemic exams (p > 0.05). In the pandemic period, exam volume followed an inverted parabolic pattern, reflecting Covid surges for the cohort and all demographic subgroups. CONCLUSION: The COVID-19 pandemic significantly decreased lung cancer screening volume and new enrollment in our urban inner-city program. Screening volumes demonstrated a parabolic curve reflecting pandemic surges following the initial wave, unlike other reports. The combination of the impact of COVID on our population and lack of staffing redundancy in the screening program, in the face of typical COVID isolation and quarantine absences, impeded early pandemic rebound of our lung cancer screening program. This highlights the necessity of fostering resilience by developing robust programmatic resources.

OBJECTIVES: Patients with Barrett's esophagus (BE) are at risk of progression to esophageal adenocarcinoma (EAC). We developed a model to predict histologic progression in patients with nondysplastic BE (NDBE). METHODS: A longitudinal study in three referral centers was performed between January 2010 and December 2019. As progression to low-grade dysplasia (LGD) can be considered an indication for ablative therapy, the study end-point was histopathologic progression to LGD, high-grade dysplasia, or EAC at 3 years after diagnosis. We used logistic regression to create the model. Seventy percent of the cohort were used to stem the model and the remaining 30% for internal validation. RESULTS: A total of 542 patients were included, 69.4% of whom were male, mean age 62.2 years. Long-segment BE at index endoscopy was diagnosed in 20.8% of the patients. After a mean follow-up of 6.7 years, 133 patients (24.5%) had histologic progression. Our model identified a neutrophil-to-lymphocyte ratio (odds ratio [OR] 2.08, 95% confidence interval [CI] 1.77-2.32, P < 0.001), BE length (OR 1.22, 95% CI 1.09-1.36, P < 0.001), age (OR 1.03, 95% CI 1.02-1.05, P = 0.02), smoking (OR 1.66, 95% CI 1.09-2.75, P = 0.04), and renal failure (OR 1.51, 95% CI 0.93-2.43, P = 0.07) as predictors of histologic progression at 3 years. The areas under the receiver operating characteristic curves of this model were 0.88 and 0.76 in the training and validation cohorts, respectively. CONCLUSION: This novel, internally validated model may predict histologic progression, even in patients with NDBE who generally have low rates of progression over time, and may contribute to enhanced patient selection for more intense surveillance programs.

BACKGROUND AND OBJECTIVES: EUS-guided drainage of pancreatic fluid collections (PFCs) has been increasingly performed using lumen-apposing metal stents (LAMS). However, recent data have suggested higher adverse event rates with LAMS compared to double pigtail plastic stents (DPS) alone. To decrease risks, there has been anecdotal use of placing DPS through the LAMS. We aimed to determine whether the placement of DPS through cautery-enhanced LAMS at time of initial placement decreases adverse events or need for reintervention. METHODS: We performed a multicenter retrospective study between January 2015 and October 2017 examining patients who underwent EUS-guided drainage of pseudocysts (PP), walled-off necrosis (WON), and postsurgical fluid collection using a cautery enhanced LAMS with and without DPS. RESULTS: There were 68 patients identified at 3 US tertiary referral centers: 44 PP (65%), 17 WON (25%), and 7 PFSC (10%). There were 35 patients with DPS placed through LAMS (Group 1) and 33 with LAMS alone (Group 2). Overall technical success was 100%, clinical success was 94%, and adverse events (bleeding, perforation, stent occlusion, and stent migration) occurred in 28% of patients. Subgroup analysis compared specific types of PFCs and occurrence of adverse events between each group with no significant difference detected in adverse event or reintervention rates. CONCLUSION: This multicenter study of various types of PFCs requiring EUS-guided drainage demonstrates that deployment of DPS across cautery-enhanced LAMS at the time of initial drainage does not have a significant effect on clinical outcomes, adverse events, or need for reinterventions.
ABSTRACT
PURPOSE: The impact of pre-bariatric surgery BMI on the incidence of colorectal adenomas in the post-operative period is unknown. Here we aim to evaluate the incidence of colorectal adenomas after bariatric surgery and to assess super morbid obesity (SMO) as a risk factor for post-operative colorectal adenomas. MATERIALS AND METHODS: An inception cohort of 1639 patients that underwent bariatric surgery between 2011 and 2019 in a referral center was retrospectively analyzed. SMO was defined as BMI > 50.0 kg/m2. Cox regression analysis was performed to assess the influence of pre-operative BMI on the primary outcome. RESULTS: A total 381 patients (23.2% of the cohort) underwent colonoscopy and included in the analysis. Mean age was 51.1 years (± 10.6) with mean BMI of 42.2 kg/m2 (± 6.2), and 49 patients (12.9%) had SMO. Median time to colonoscopy was 3.5 years. One hundred nine patients (28.6%) had colorectal polyps, and 38/109 (34.8%) had advanced adenoma. Two patients had colorectal cancer (CRC). Pre-procedural SMO was associated with diagnosis of colorectal polyp (HR 2.4, 95% CI 1.5-3.9, p < 0.001) and advanced adenomas (HR 4.2, 95% CI 2.0-8.9, p < 0.001) upon adjustment to previously reported risk factors of CRC. CONCLUSION: Pre-procedural SMO is associated with increased risk of colorectal adenomas after bariatric surgery compared to obese and morbidly obese individuals. Pre-operative BMI should be incorporated into post-operative screening plan in this population.

Background and study aims Rectal neuroendocrine tumors (NETs) are often discovered incidentally and may be misidentified as adenomatous polyps. This can result in a partial resection at the index procedure, and lesions are often referred for staging or evaluation for residual disease at the resection site. The aim of this study was to identify the ideal method to confirm complete excision of small rectal NETs. Patients and methods Data from patients with a previously resected rectal NET referred for follow-up endoscopy or endoscopic ultrasound (EUS) were retrospectively reviewed. Univariate analysis was performed on categorical data using the Chi-squared test. Results Forty-nine patients with rectal NETs were identified by pathology specimens. Of those, 39 underwent follow-up endoscopy or EUS and were included. Baseline characteristics included gender (71â% F, 29â% M), age (57.2â±â13.4 yrs) lesion size (7.3â±â4.2âmm) and location. The prior resection site was identified in 37/39 patients who underwent tissue sampling. Residual NET was found histologically in 14/37 lesions. All residual disease was found during salvage endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) and 43â% had a normal-appearing scar. Every patient undergoing EUS had an unremarkable exam. Initial cold biopsy polypectomy ( P â=â0.006), visible lesions ( P â=â0.001) and EMR/ESD of the prior resection site ( P â=â0.01) correlated with residual NET. Conclusions Localized rectal NETs may be incompletely removed with standard polypectomy. If an advanced resection is not performed initially, repeat endoscopy with salvage EMR or ESD of the scar should be considered. For small rectal NETs, biopsy may miss residual disease when there is no visible lesion and EUS appears to have no benefit.
ABSTRACT
BACKGROUND: Patient's with Barrett's esophagus (BE) are at risk of progression to esophageal adenocarcinoma (EAC). Neutrophil to lymphocyte ratio (NLR) was found to be a predictor of poor prognosis in patients with EAC; however, its performance in premalignant esophageal lesions is vague. We aimed to evaluate the utility of NLR as a predictor of histologic progression in patients with BE. METHODS : A prospective cohort of patients with proven BE in a tertiary referral center was retrospectively analyzed. All biopsies were reviewed by an expert gastrointestinal pathologist. The discriminatory capacity of NLR was evaluated by area under the receiver operating characteristic (AUC) curve analysis and Cox regression analysis. RESULTS: 324 patients (mean age 62.3 years, 241 [74.4â%] males) were included in the final analysis. Overall, 13 patients demonstrated histologic progression to neoplasia over a mean follow-up of 3.7 years (progression risk 1.0â% per year). The AUC of NLR for progression to high grade dysplasia (HGD) or EAC was 0.88 (95â% confidence interval [CI] 0.83â-â0.96), and baseline NLR was associated with a 3-fold increase of progression to HGD and EAC during follow-up (hazard ratio [HR] 3.2, 95â%CI 1.5â-â5.8; Pâ<â0.001). Notably, in a subgroup analysis of patients with nondysplastic BE (NDBE) at presentation, NLR was also a risk factor for histologic progression (HR 2.4, 95â%CI 1.7â-â3.4; Pâ<â0.001). CONCLUSION: NLR predicted histologic progression in patients with BE. Patients with NDBE and NLR above 2.4 can be considered for specific surveillance programs with shorter intervals between sessions.

Recreational water use (RWU) injuries span from superficial lacerations to even death. Given the global popularity of RWU, radiologists should be aware of the common mechanisms and key imaging findings related to injuries in this setting. The goal of this article is to depict common RWU injuries and their emergent radiographic findings, which may have both important surgical and management implications. We present a broad review with case illustrations of these injuries seen at our level 1 trauma center showing the breadth of injury that can occur, general mechanisms and sample imaging findings.

BACKGROUND: Open subpectoral biceps tenodesis (OSBT) with cortical button fixation can deliver acceptable results for long head of the biceps (LHB) pathology with the benefit of smaller bone tunnel diameter and a potential reduced risk of postoperative humeral shaft fracture. However, functional outcomes and complications of a button-only technique with a small diameter tunnel in the subpectoral region have not been studied sufficiently. PURPOSE: We sought to determine whether OSBT with cortical button fixation results in significant functional improvements from preoperative to final follow-up. The secondary purpose was to determine whether there is a lower risk of major postoperative complications. METHODS: A retrospective review of patients who underwent OSBT with cortical button fixation at one institution was conducted with objective measurements and clinical outcomes collected with a minimum of 2 years of follow-up. Surgical data was collected for analysis. Objective measures obtained at follow-up included physical exam, strength testing using a handheld dynamometer, and Long-Head of the Biceps score. Clinical outcomes were measured using the following validated questionnaires preoperatively and postoperatively: American Shoulder and Elbow Surgeons score (ASES), Disabilities of the Arm, Shoulder and Hand score (DASH), and Oxford Shoulder Score (OSS). RESULTS: Sixty-one patients with mean age of 53.1 ± 10.1 years at the time of surgery were enrolled in the study. Mean follow-up time was 42.4 ± 16.9 months (range: 24 to 64 months). The postoperative LHB score was 95.5 ± 6.1 (range: 77 to 100). All functional outcome measures (ASES, DASH, and OSS) demonstrated statistically significant improvements at final follow-up (p < 0.05 for each). At total of 92.5% of patients stated they would have the procedure again if necessary. Mean elbow flexion strength on the operative side measured 98.7% ± 15.9% (range: 74.1% to 142.3%) of the contralateral arm. The mean LHB tendon diameter was 5.7 ± 0.8 mm and mean tunnel diameter was 5.9 ± 0.7 mm. There were no cases of intraoperative or postoperative fracture, infection, or Popeye deformity noted during the follow-up period. CONCLUSION: Subpectoral biceps tenodesis with cortical button fixation is a safe and effective surgical treatment option to relieve pain and restore function.

Since the original description of pancreatic fluid collections (PFC) in 1761 by Morgagni, their diagnosis, description, and management have continued to evolve. The mainstay of therapy for symptomatic PFCs has been the creation of a communication between a PFC and the stomach, to enable drainage. Surgical creation of these drainage conduits had been the gold standard of therapy; however, there has been a paradigm shift in recent years with an increasing role of endoscopic drainage. The techniques of endoscopic drainage have evolved from blind fluid aspiration to include endoscopic necrosectomy and the placement of lumen-apposing metal stents.

The purpose of this study was to examine outcomes after cryopreserved tri-cortical iliac crest allograft reconstruction for glenoid bone loss in patients with shoulder instability. 10 patients completed the required assessments at a mean follow up of 4.5 years. At final follow up, mean ASES was 92⯱â¯12, mean WOSI was 315⯱â¯319, with good range of motion. None of the final radiographs demonstrated graft resorption or failure of hardware. The data demonstrated that patients who were treated with glenoid bone grafting with cryopreserved tri-cortical iliac crest allograft can expect good range of motion and functional capacity.
ABSTRACT
BACKGROUND AND AIMS: Ulcerative colitis (UC) patients with progression of their disease despite optimized medical therapy may warrant "curative" proctocolectomy with end ileostomy or ileo-anal pouch (IPAA) anastomosis. The aim of our study was to assess the incidence of later recurrent ileitis that lead to altering the initial diagnosis to Crohn's disease (CD). METHODS: A retrospective analysis was conducted on the inflammatory bowel disease database at Lenox Hill Hospital. The database consisted of patients that were diagnosed with UC or CD based on clinical assessment, endoscopic appearance, gross and histological examination, and imaging between 1960 and 2015. The post-colectomy follow-up period was at least 10 years. Recurrent disease was classified by evidence of transmural inflammation in the distal ileum, fistulizing disease, or stricturing disease. RESULTS: From our IBD database, we identified 128 patients who underwent elective or urgent colectomy with the preoperative diagnosis of UC. Thirty-two (25%) had either an IPAA or end ileostomy with documented recurrence of inflammation in the small bowel mucosa consistent with CD. There was no significant difference between the type of surgical approach and the chance of recurrent disease (p = .20). The average time to clinically significant recurrence was 5 years. CONCLUSION: The incidence of recurrent CD following colectomy for ulcerative colitis, when followed postoperatively for an average of 20 years, was 25%, considerably more than previously reported. Patients who come to colectomy for ulcerative colitis and are followed for at least 10 years show a high incidence of recurrent Crohn's disease in the ileostomy or ileo-anal pouch. Extended follow-up should be included in patients coming to colectomy for ulcerative colitis before they should be considered cured of their disease.
