Diffuse Large B-Cell Lymphoma of the Colon in an Asymptomatic Patient.

Extranodal lymphomas of the gastrointestinal (GI) tract are known entities, but primary lymphoma of the colon is extremely rare. Symptoms are non-specific, such as abdominal pain, bloody diarrhea, unintentional weight loss, night sweats, and changes in bowel habits. Some patients do not have any specific symptoms, which makes diagnosis extremely difficult.

Propensity matched analysis of minimally invasive versus conventional isolated aortic valve replacement.

Objective: To analyse the early and mid-term outcome of patients undergoing conventional aortic valve replacement (AVR) versus minimally invasive via hemi-sternotomy aortic valve replacement (MIAVR).

Methods: A single centre retrospective study involving 653 patients who underwent isolated aortic valve replacement (AVR) either via conventional AVR ( = 516) or MIAVR ( = 137) between August 2015 and March 2020. Using pre-operative characteristics, patients were propensity matched (PM) to produce 114 matched pairs.
