Closed-Loop Gastric Outlet Obstruction Secondary to Duodenal Ulcer in a Patient With Esophageal Stricture.

Closed-loop gastric outlet obstruction (GOO) is a rare complication that results from a mechanical obstruction in the pylorus or duodenum. In the early 1990s, the common cause of GOO was peptic ulcer disease, accounting for 5% to 10% of hospital admissions. Peptic ulcer disease is the disruption of the mucosal integrity in the stomach and duodenum and can be categorized into gastric ulcers and duodenal ulcers. With the treatment for Helicobacter  pylori and the increased use of proton pump inhibitors (PPI), GOO now occurs in fewer than 5% of patients with duodenal ulcer disease and even less in those with gastric ulcer disease. Although the morbidity of duodenal ulcers has been declining in recent years, the incidence of post-bulbar duodenal ulcer (PBDU) remains at a constant 9.33%, primarily due to diagnostic and therapeutic difficulties. Additionally, fewer than 5% of obstructing duodenal ulcers are caused by PBDU, and even fewer are located in the second or third portions of the duodenum. Ulcers located in the distal part of the duodenum raise concern for syndromes associated with hypersecretion of acid, including Zollinger-Ellison syndrome (ZES). The ZES is rare, accounting only for 0.1% of all duodenal ulcers. Here, we present a case where a patient with esophageal stricture developed a rare case of closed-loop GOO secondary to a duodenal ulcer. The patient, initially treated for esophageal perforation, developed an esophageal stricture. The patient was being worked up for ZES and multiple endocrine neoplasia link type 1 (MEN1) syndrome due to his concerning laboratory findings and rare clinical presentation.

A Technique to Minimize Aerosolization During Percutaneous Tracheostomy in COVID-19 Patients.

BACKGROUND: The SARS-CoV-2 pandemic has caused respiratory failure in many patients. With no effective treatment or vaccine, prolonged mechanical ventilation is common in survivors. Timing and performance of tracheostomy, for both patient and surgical team safety, remains a question. Here within, we report our experience with percutaneous dilatational tracheostomy with modification to minimize aerosolization. METHODS: A modified percutaneous dilatational tracheostomy technique is described. The technique was performed on 10 patients in the surgical intensive care unit. RESULTS: Ten patients underwent percutaneous dilatational tracheostomy. There were 7 males, and the average age for the group was 60.8 years. The average number of ventilator days before the operation was 26.3. All procedures were successful, and no patient had any procedure-related complications. CONCLUSIONS: The procedure described was successful in our patient population. We believe that this approach is safe for patients with coronavirus disease 2019 and limits aerosolization during the operation. LEVEL OF EVIDENCE: Level IV, case series.

Quality improvement initiative: Preventative Surgical Site Infection Protocol in Vascular Surgery.

Objective A quality improvement initiative was employed to decrease single institution surgical site infection rate in open lower extremity revascularization procedures. SUMMARY BACKGROUND DATA: In an attempt to lower patient morbidity, we developed and implemented the Preventative Surgical Site Infection Protocol in Vascular Surgery. Surgical site infections lead to prolonged hospital stays, adjunctive procedure, and additive costs. We employed targeted interventions to address the common risk factors that predispose patients to post-operative complications. Methods Retrospective review was performed between 2012 and 2016 for all surgical site infections after revascularization procedures of the lower extremity. A quality improvement protocol was initiated in January 2015. Primary outcome was the assessment of surgical site infection rate reduction in the pre-protocol vs. post-protocol era. Secondary outcomes evaluated patient demographics, closure method, perioperative antibiotic coverage, and management outcomes. Results Implementation of the protocol decreased the surgical site infection rate from 6.4% to 1.6% p = 0.0137). Patient demographics and comorbidities were assessed and failed to demonstrate a statistically significant difference among the infection and no-infection groups. Wound closure with monocryl suture vs. staple proved to be associated with decreased surgical site infection rate ( p < 0.005). Conclusions Preventative measures, in the form of a standardized protocol, to decrease surgical site infections in the vascular surgery population are effective and necessary. Our data suggest that there may be benefit in the incorporation of MRSA and Gram-negative coverage as part of the Surgical Care Improvement Project perioperative guidelines.

An uncommon case of severe accidental hypothermia in an urban setting.

Accidental hypothermia is an uncommon presentation in urban settings. Here we present a patient admitted with a core temperature of 26.6°C (80°F) and a serum potassium of 8.5 mmol/l who subsequently went into cardiac arrest. After > 90 min of active cardiopulmonary resuscitation and peak serum potassium of >12 mmol/l, the patient had a spontaneous return of circulation. The patient's hospital course was complicated by compartment syndrome of his forearm; however, he was discharged home without any lasting neurological damage.
