Introduction: Optimal management of toxic megacolon as a consequence of Cl. difficile colitis is still matter of controversy, as well as timing of available therapeutic modalities. In this article we report a case of severe C. difficile colitis associated with toxic megacolon in a pregnant patient with Covid 19, who was successfully treated conservatively. Case Report: A 33-years old pregnant woman contracted SARS-CoV-2 in the 32nd week of pregnancy. She was admitted to regional hospital and treated extensively by wide-spectrum antibiotics. After the delivery she developed severe form of Cl. difficile colitis with toxic megacolon. In spite of severe clinical picture, the patient was treated conservatively, with high initial oral doses of vancomycin, with subsequent tapering. The outcome of the treatment was complete recovery and colonic functions were regained completely. Conclusion: In conclusion, our case shows that in younger patients, who were fit before occurrence of Cl. difficile colitis and toxic megacolon, conservative therapy should be tried as long as possible before turning to colectomy, since chances for cure without surgery are considerable.
