Operative strategies and outcomes for patients with severe pulmonary artery hypertension and intestinal obstruction: case series from single institution-sharing lessons to improve surgical outcomes.

Pulmonary hypertension is a known perioperative risk factor that carries a high morbidity and mortality rate. Severe pulmonary hypertension is related to high morbidity after general anaesthesia. We are reporting three patients with underlying severe pulmonary hypertension, who presented with intestinal obstruction managed with different perioperative approaches.

Prospective diagnostic study on the use of narrow-band imaging on suspicious lesions during colonoscopy examination.

Narrow-band imaging (NBI) has a good diagnostic accuracy to differentiate between neoplastic and non-neoplastic colorectal lesions. This study explores the diagnostic validity of NBI colonoscopy as well as its associated factors related to neoplastic and non-neoplastic colorectal lesions.
