Abstract:
Extrapulmonary involvement of coronavirus-19 disease (COVID-19) is being documented and studied at an increasing frequency. Specifically, gastrointestinal involvement is hypothesized to occur due to cellular entry via the ACE2 receptor found in gastrointestinal epithelial cells, causing inflammation and symptoms such as abdominal pain, nausea/vomiting, and diarrhea. We present the case of a 45-year-old female with recent severe COVID-19 infection and early gastrointestinal symptoms who later presented with worsening abdominal pain, nausea, vomiting, and constipation after initial discharge. She was diagnosed with a large bowel obstruction and underwent urgent exploratory laparotomy, which revealed a stricture of the distal transverse colon. Following segmental resection, the patient experienced resolution of symptoms. We hypothesize that this patient's colonic stricture arose secondary to severe COVID-19-induced bowel inflammation.

Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
