Colonoscopy is a commonly performed low-risk gastrointestinal procedure that may rarely result in a serious complication. Patients presenting with abdominal pain and fever after colonoscopy may have acute cholecystitis. The underlying mechanisms are unclear. Such patients usually present within 72 hours of the procedure. Treatment includes intravenous antibiotics and cholecystectomy. We present our experience of two such cases; a 56-year-old man and a 21-year-old man, both of whom developed acute calculus cholecystitis within 48 hours after a routine colonoscopy. Their symptoms resolved after cholecystectomy.

Chronic intestinal pseudo-obstruction (CIPO) is a rare syndrome associated with significant mortality and morbidity. It mimics the signs and symptoms of intestinal obstruction in the absence of an anatomic lesion causing obstruction. Here we present a case of a young male with severe alcohol abuse disorder who initially presented with signs and symptoms of alcohol withdrawal but was found to have abdominal distension. Imaging studies revealed severe small and large bowel dilatation without any organic lesion. He continued to have marked intestinal dilatation for the subsequent few months. Alcohol cessation eventually led to a marked reduction in his symptoms and a decrease in intestinal dilatation. The occurrence of CIPO because of alcohol abuse is rare, and we explore the possible association between the two entities.

Background Human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) share common modes of transmission; hence HBV and HCV infection are more prevalent among HIV patients. The co-infection with HIV/HBV, HIV/HCV, or HIV/HBV/HCV carries significant morbidity, with higher progression rates to end-stage liver disease or hepatocellular carcinoma (HCC). Methods We conducted a retrospective study among HIV adult patients co-infected with HBV or HCV and those with HCV, HIV, and HBV triple infection enrolled in the outpatient clinic of BronxCare Hospital between the years 2010 and 2021. Records were reviewed to obtain demographic data, including age and sex, hepatitis B surface antigen (HBsAg), anti-HCV antibodies, and CD4 T-lymphocyte count test results. Male and female patients ≥18 years with confirmed HIV by double enzyme-linked immunoassay (ELISA) and western blot, who underwent serology testing for both HBsAg and anti-HCV, were included in the study. Results In this study, 11355 HIV patients were included, comprising 7020 (61.8%) males and 4335 (38.2%) females. A total of 410 (3.6%) were hepatitis B positive, 1432 (12.6%) were hepatitis C positive, and 127 (1.1%) were both hepatitis B and C positive. Fifty-two (0.5%) patients were diagnosed with HCC. The majority of the patient with HCC (50%, n =26) were hepatitis C serology positive (p<0.001) while 9.6% (n=5) were positive for both hepatitis C and hepatitis B (p<0.001). Conclusion HIV/HBV/HCV triple-infected patients had a lower rate of HCC compared to HIV/HCV co-infected patients. HIV without hepatitis C or hepatitis B is an independent risk factor for HCC.
