Background
/Aims: Endoscopic resection has become the preferred treatment approach for select early esophageal adenocarcinoma (EAC); however, the epidemiology of early stage disease has not been well defined.
Methods
Surveillance Epidemiology and End Results (SEER) data were analyzed to determine age-adjusted incidence rates among major epithelial carcinomas, including EAC, from 1973 to 2017. The percent change in incidence over time was compared according to tumor subtype. Early T-stage, node-negative EAC without metastasis was examined from 2004 to 2017 when precise T-stage data were available.
Results
The percent change in annual incidence from 1973 to 2017 was 767% for EAC. Joinpoint analysis showed that the average annual percent change in EAC from 1973 to 2017 was 5.11% (95% confidence interval, 4.66%–5.56%). The annual percent change appeared to plateau between 2004 and 2017; however, early EAC decreased from 2010 to 2017, with an annual percent change of -5.78%.
Conclusions
There has been a 7-fold increase in the incidence of EAC, which was significantly greater than that of the other major epithelial malignancies examined. More recently, the incidence of early EAC has been decreasing. Approximately one in five patients has node negative, potentially resectable early stage disease.

Perception of Gastrointestinal Endoscopy Personnel on Society Recommendations on Personal Protective Equipment, Case Selection, and Scope Cleaning During Covid-19 Pandemic: An International Survey Study: Parit Mekaroonkamol, Kasenee Tiankanon, Rapat Pittayanon, Wiriyaporn Ridtitid, Fariha Shams, Ghias Un Nabi Tayyab, Julia Massaad, Saurabh Chawla, Stanley Khoo, Siriboon Attasaranya, Nonthalee Pausawasdi, Qiang Cai, Thawee Ratanachu-ek, Pradermchai Kongkham, Rungsun Rerknimitr; Clin Endosc 2022;55(2):215-225. Published online September 29, 2021; DOI: https://doi.org/10.5946/ce.2021.051

Abstract PDF Supplementary Material PubReader ePub: Background
/Aims: The Thai Association for Gastrointestinal Endoscopy published recommendations on safe endoscopy during the coronavirus disease 2019 (COVID-19) pandemic. This study aimed to assess the practicality and applicability of the recommendations and the perceptions of endoscopy personnel on them.
Methods
A validated questionnaire was sent to 1290 endoscopy personnel globally. Of these, the data of all 330 responders (25.6%) from 15 countries, related to the current recommendations on proper personal protective equipment (PPE), case selection, scope cleaning, and safety perception, were analyzed. Ordinal logistic regression was used to determine the relationships between the variables.
Results
Despite an overwhelming agreement with the recommendations on PPE (94.5%) and case selection (95.5%), their practicality and applicability on PPE recommendations and case selection were significantly lower (p=0.001, p=0.047, p<0.001, and p=0.032, respectively). Factors that were associated with lower sense of safety in endoscopy units were younger age (p=0.004), less working experience (p=0.008), in-training status (p=0.04), and higher national prevalence of COVID-19 (p=0.003). High prevalent countries also had more difficulty implementing the guidelines (p<0.001) and they considered the PPE recommendations less practical and showed lower agreement with them (p<0.001 and p=0.008, respectively). A higher number of in-hospital COVID-19 patients was associated with less agreement with PPE recommendations (p=0.039).
Conclusions
Using appropriate PPE and case selection in endoscopic practice during a pandemic remains a challenge. Resource availability and local prevalence are critical factors influencing the adoption of the current guidelines.

Practice Patterns and Use of Endoscopic Retrograde Cholangiopancreatography in the Management of Recurrent Acute Pancreatitis: Jonathan B. Reichstein, Vaishali Patel, Parit Mekaroonkamol, Sunil Dacha, Steven A. Keilin, Qiang Cai, Field F. Willingham; Clin Endosc 2020;53(1):73-81.

Background
/Aims: There are conflicting opinions regarding the management of recurrent acute pancreatitis (RAP). While some physicians recommend endoscopic retrograde cholangiopancreatography (ERCP) in this setting, others consider it to be contraindicated in patients with RAP. The aim of this study was to assess the practice patterns and clinical features influencing the management of RAP in the US.
Methods
An anonymous 35-question survey instrument was developed and refined through multiple iterations, and its use was approved by our Institutional Review Board. The survey was distributed via email to 408 gastroenterologists to assess the practice patterns in the management of RAP in multiple clinical scenarios.
Results
The survey was completed by 65 participants representing 36 of the top academic/tertiary care centers across the country. Approximately 90.8% of the participants indicated that they might offer or recommend ERCP in the management of RAP. Multinomial logistic regression analysis revealed that ductal dilatation and presence of symptoms were the most predictive variables (p<0.001) for offering ERCP.
Conclusions
A preponderance of the respondents would consider ERCP among patients with RAP presenting to tertiary care centers in the US. Ductal dilatation, presence of symptoms, and pancreas divisum significantly increased the likelihood of a recommendation for ERCP

Long -Term Survival in Stage IV Esophageal Adenocarcinoma with Chemoradiation and Serial Endoscopic Cryoablation: Zachary Spiritos, Parit Mekaroonkamol, Bassel F. El- Rayes, Seth D. Force, Steven A. Keilin, Qiang Cai, Field F. Willingham; Clin Endosc 2017;50(5):491-494. Published online April 24, 2017; DOI: https://doi.org/10.5946/ce.2017.006

Abstract PDF PubReader ePub

Esophageal cancer has a poor overall prognosis and is frequently diagnosed at a late stage. Conventional treatment for metastatic esophageal cancer involves chemotherapy and radiation. Local disease control plays a significant role in improving survival. Endoscopic spray cryotherapy is a novel modality that involves freezing and thawing to produce local ablation of malignant tissue via ischemic mechanisms. Spray cryotherapy has been shown to be effective, particularly for early T-stage, superficial esophageal adenocarcinomas. We present the case of a 72-year-old-male with locally recurrent stage IV esophageal adenocarcinoma and long-term survival of 7 years to date, with concurrent chemoradiation and serial cryoablation. He remains asymptomatic and continues to undergo chemotherapy and sequential cryoablation. The findings highlight the long-term safety and efficacy of cryotherapy in combination with chemoradiation, and suggest that cryoablation may have an additive role in the treatment of advanced stage esophageal adenocarcinoma.
