Laparoscopic Cholecystectomy in the Time of Coronavirus: A Level-1 Trauma Center's Experience.

INTRODUCTION: Laparoscopic cholecystectomy (LC), one of the most common surgical procedures performed in the U.S., offers a window into the effects of the COVID-19 pandemic on routine surgical care. The purpose of our study was to analyze the effects of the COVID-19 pandemic at a Level-1 trauma center on the performance rate of non-elective LC over time. METHODS: A retrospective chart review from July 2019 to December 2020 identified all non-elective LC cases performed at a level-1 trauma center. Patients were categorized into 4 temporal phases along the course of the pandemic based on statewide incidence data on COVID-19: pre-pandemic, peak 1, recovery, and peak 2. We compared the phases based on demographic information and outcomes. RESULTS: In total, 176 patients were reviewed. The performance rate in cases/day varied as follows: pre-pandemic .61, 1st peak .34, recovery .44, and 2nd peak .53. The complication rate was highest in the 2nd peak (16%) (P < .05). Compared to the pre-pandemic period, the intra-pandemic period had a higher incidence of complicated gallbladder disease (P < .05). In the non-elderly subgroup, complicated gallbladder disease was significantly more prevalent in the intra-pandemic period compared to the pre-pandemic period (25% vs 10%, P < .05). CONCLUSIONS: Our data suggests a learning curve throughout the course of the pandemic, reflecting a stepwise increase in the performance rate of LC. The higher incidence of complicated gallbladder disease in the intra-pandemic period may imply patient hesitancy to seek routine surgical care, especially among younger patients.

Unexplained Methemoglobinemia in Coronavirus Disease 2019: A Case Report.

Methemoglobinemia is a rare disorder of the blood in which there is an increase in methemoglobin, which occurs when hemoglobin is present in the oxidized form. Methemoglobin impairs hemoglobin's ability to transport oxygen, produces functional anemia, and leads to tissue hypoxia. We report the successful management of a case of refractory hypoxia due to acutely acquired methemoglobinemia in a patient undergoing treatment for coronavirus disease 2019 (COVID-19) pneumonia. The cause of methemoglobinemia in this patient remains unknown. Hypoxia and methemoglobinemia did not respond to methylene blue and required administration of packed red blood cell transfusions.
