Long‐term follow up of abdominal rectosigmoidectomy with posterior end‐to‐side stapled anastomosis for Chagas megacolon

Aim  Chagas’ disease is an endemic parasitosis found in Latin America. The disease affects different organs, such as heart, oesophagus, colon and rectum. Megacolon is the most frequent long‐term complication, caused by damage to the myoenteric and submucous plexus, ultimately leading to a functional barrier to the faeces. Patients with severe constipation are managed surgically. The study aimed to analyse the 10‐year minimum functional outcome after rectosigmoidectomy with posterior end‐to‐side anastomosis (RPESA).
