H. pylori clarithromycin resistance in the USA exceeds the estimated 20 % prevalence compatible with successful empiric antibiotic therapy. This resistance resulted in a significant rate of treatment failure in all sites surveyed. Empiric therapy in the USA should be used with caution until there is better regional or local determination of H. pylori antibiotic resistance.
Background and study aims The COVID-19 pandemic has had a profound impact on gastroenterology training programs. We aimed to objectively evaluate procedural training volume and impact of COVID-19 on gastroenterology fellowship programs in the United States.
Methods This was a retrospective, multicenter study. Procedure volume data on upper and lower endoscopies performed by gastroenterology fellows was abstracted directly from the electronic medical record. The study period was stratified into 2 time periods: Study Period 1, SP1 (03/15/2020 to 06/30/2020) and Study Period 2, SP2 (07/01/2020 to 12/15/2020). Procedure volumes during SP1 and SP2 were compared to Historic Period 1 (HP1) (03/15/2019 to 06/30/2019) and Historic Period 2 (HP2) (07/01/2019 to 12/15/2019) as historical reference.
Results Data from 23 gastroenterology fellowship programs (total procedures = 127,958) with a median of 284 fellows (range 273–289; representing 17.8 % of all trainees in the United States) were collected. Compared to HP1, fellows performed 53.6 % less procedures in SP1 (total volume: 28,808 vs 13,378; mean 105.52 ± 71.94 vs 47.61 ± 41.43 per fellow; P < 0.0001). This reduction was significant across all three training years and for both lower and upper endoscopies (P < 0.0001). However, the reduction in volume was more pronounced for lower endoscopy compared to upper endoscopy [59.03 % (95 % CI: 58.2–59.86) vs 48.75 % (95 % CI: 47.96–49.54); P < 0.0001]. The procedure volume in SP2 returned to near baseline of HP2 (total volume: 42,497 vs 43,275; mean 147.05 ± 96.36 vs 150.78 ± 99.67; P = 0.65).
Conclusions Although there was a significant reduction in fellows’ endoscopy volume in the initial stages of the pandemic, adaptive mechanisms have resulted in a return of procedure volume to near baseline without ongoing impact on endoscopy training.
Cholestasis is a general feature of intrahepatic or extrahepatic biliary obstruction by various mechanisms including cirrhosis, stricture, choledocholithiasis, hepatitis, and neoplasms. Neoplasms can directly impinge on the hepatobiliary tree resulting in bile stasis. Stauffer’s syndrome is another variant of this neoplastic process that can cause cholestasis and liver enzyme elevation without any direct hepatobiliary obstruction, and is thus categorized as a paraneoplastic syndrome of unclear pathophysiology. We report a first case of metastatic prostate adenocarcinoma with features of Stauffer’s syndrome that reversed completely on androgen deprivation therapy. This is in contrast to a previously reported case of Stauffer’s syndrome due to metastatic prostate adenocarcinoma, which reversed partially to androgen deprivation therapy. Our case demonstrates the importance of early recognition of Stauffer’s syndrome and underlying neoplasms in patients who present with cholestasis without clear evidence of intrahepatic or extrahepatic biliary obstruction, which may lead to early initiation of treatment.
Aortoesophageal fistula is a rare and serious condition that carries a high mortality rate. We present a case of overt gastrointestinal bleeding from an aortoesophageal fistula in a patient with chronic infection of an endovascular prosthesis with Coxiella burnetii.
A 63-year-old man with a history of hypothyroidism presented with a 10-year history of dysphagia to solid foods and liquids. He had had worsening of his symptoms for 6 months before presentation, with an associated weight loss of 27 kg (60 lb). An anterior-posterior radiograph of the chest obtained on admission while the patient was in the upright position showed a mediastinal structure with internal debris (Panel A). Computed tomographic imaging revealed food extending from the proximal esophagus to the esophagogastric junction (Panel B shows the coronal scan, Panel C the cross-section view, and Panel D the sagittal view). Esophagogastroduodenoscopy revealed a dilated esophagus with food, and no strictures or masses were identified. The patient received a diagnosis of achalasia causing megaesophagus. Achalasia is caused by impaired relaxation of the lower esophageal sphincter and typically manifests as dysphagia to both solid foods and liquids. The patient underwent esophagectomy with a gastric pull-through procedure, and a jejunal feeding tube was placed. Eight months later, he had good oral intake and the tube was removed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
