Objective:
The authors aim to demonstrate that the current drive-through testing model at one health district was improved in certain parameters compared to a previous testing protocol, and also aim to provide the methodology of the current model for other COVID-19 testing sites to potentially emulate.
Methods:
Initially, a small drive-through site was constructed at a converted tuberculosis clinic, but due to an increase in testing needs, an expanded point of screening and testing (POST) system was developed in an event center parking lot to administer tests to a higher volume of patients.
Results:
An average of 51.1 patients were tested each day (2.0 tests per personnel in PPE per hour) at the initial tuberculosis clinic drive-through site, which increased to 217.8 patients tested each day (5.9 tests per personnel in PPE per hour) with the new drive-through POST system (p<0.001). Mean testing time was 3.4 minutes and the total time on site averaged 14.4 minutes.
Conclusions:
This POST drive-through testing system serves as an efficient, safe, and adaptable model for high volume COVID-19 nasopharyngeal swabbing that the authors recommend other COVID-19 testing sites nationwide consider adopting for their own use.
Background
Superior mesenteric arteriovenous fistula is a rare vascular anomaly often presenting with sequelae of portal hypertension, heart failure, or mesenteric ischemia. This report describes a patient with a previously unidentified superior mesenteric arteriovenous fistula who presented with variceal bleeding, thought to be the leading cause of mortality associated with this condition. Although this patient was initially referred for a transjugular intrahepatic portosystemic shunt procedure, following a thorough review of her clinical history and imaging, she instead underwent embolization of the arteriovenous fistula likely responsible for her symptoms.
Case Presentation
A 75-year-old woman with a past surgical history of extensive small bowel resection presented with active variceal bleeding requiring transfusions. She was referred to vascular and interventional radiology for transjugular intrahepatic portosystemic shunt procedure; however, her clinical presentation was inconsistent with cirrhosis. This prompted a further review of her imaging, which identified a superior mesenteric arteriovenous fistula as the probable etiology of her varices. This fistula was subsequently embolized with a vascular plug and follow-up upper endoscopy at 1-month demonstrated complete resolution of her varices.
Conclusions
This report highlights a potential etiology of variceal bleeding in the acutely ill patient. Through a thorough consultation, the patient described here was able to avoid a procedure with the potential to cause catastrophic consequences, and instead receive the appropriate treatment for an uncommon condition.

Background:There is no current consensus on the management of large hiatal hernias concomitant with performance of a sleeve gastrectomy procedure. Proposed solutions have included performing a modified Nissen fundoplication, performing cruroplasty alone, utilizing the Linx device, performing cruroplasty with reinforcement material, and avoiding the sleeve procedure altogether in favor of a bypass procedure in order to minimize gastroesophageal reflux. Urinary bladder matrix (UBM) represents a biologically derived material for use in hiatal hernia repair reinforcement with the potential to improve durability of repair without incurring the risks of other reinforcement materials.Methods: This study reports the results of a retrospective chart review of 32 cases of large hiatal hernia repair utilizing both primary crural repair and UBM reinforcement concomitant with laparoscopic sleeve gastrectomy by a single surgeon. Hernia diameter averaged 6 cm (range 4 -9 cm). After an average of 1 year followup, 30 patients were assessed for subjective symptoms of gastroesophageal reflux (GERD) using the Gastroesophageal Reflux Disease-Health Related Quality of Life (GERD-HRQL) score. Twenty patients were evaluated with either upper gastrointestinal (GI) series, endoscopy, or both.
Results:Each repair was successful and completed laparoscopically concomitant with sleeve gastrectomy. Anterior and posterior cruroplasty was performed using interrupted 0-Ethibond suture using the Endostitch device. The UBM graft exhibited favorable handling characteristics placed as a keyhole geometry sutured to the crura with absorbable suture. A careful chart review was undertaken to assess for complications. There have been no reoperations. After a median of 12 months (range, 4 -27 months) of followup, an assessment of recurrences or long-term complications was completed. Median GERD-HRQL score was 6, with a range of 0 to 64 (of possible 75), indicating very low-level reflux symptomatology. Follow-up upper GI radiographs or endoscopy were obtained in 20 cases and show intact repairs.
Conclusion:In this series of 32 cases, laparoscopic cruroplasty with UBM graft reinforcement has been effective and durable at 12 months of followup. This technique may offer one satisfactory solution for large hiatal hernia repair concomitant with laparoscopic sleeve gastrectomy that may achieve a durable repair with low GERD symptoms.
