Two female adult buffaloes were presented with a history of anorexia, suspended rumination, ruminal tympany, complete cessation of defecation. Clinical examination revealed respiratory distress due to distension of rumen and per rectal examination revealed collapsed intestines and empty rectum. Emergency exploratory laparo-rumenotomy was performed through left paralumbar fossa and ruminal exploration revealed that the reticulo-omasal orifice was obstructed with round shaped hard mass i.e. phytobezoar in one case and tennis ball in the other. The rumen incision was closed as per the standard technique The laparotomy incision and skin incision was closed in routine manner. In the present study, timely diagnosis and their surgical management saved the life of the animal. The present communication reports complications caused due to mechanical obstruction of the reticulo-omasal orifice leading to reticulitis, severe constipation and cessation of defaecation in two female buffaloes.
