Abstract
Introduction and importance: Colonic pseudo-obstruction (CPO) is characterized by massive colonic dilatation of the large intestine without mechanical obstruction. In this study, we report our surgical experience in treating refractory CPO with increased anal sphincter tone, suggested as type IV dyssynergia.

Case presentation: A 48-year-old man with intellectual disability, depression, heart failure, and end-stage renal disease presented with acute exacerbation of CPO. He had a history of chronic constipation and abdominal distension. Colonic dilatation and defecation difficulty persisted despite medication and repeated colonoscopic decompression. Anal manometry results indicated type IV dyssynergia with increased rectal pressure. Hartmann's operation was performed to resect the redundant megacolon and to avoid increased anal sphincter pressure during defecation. Hypoganglionosis was observed in the resected colon, which could worsen the chronic process of CPO.

Clinical discussion: Meticulous evaluation and careful management are required to treat CPO patients because the pathophysiology of CPO has not yet been clearly identified. Proper surgical treatment is needed for patients with refractory CPO.

Conclusion: CPO requires meticulous evaluation and careful management owing to the risk of bowel perforation. Precise evaluation to identify other factors affecting defecation problems accompanied by CPO is required to make appropriate treatment decisions.
