The study aimed at determination of the cecostomy technique that will preserve the long-term maximal diameter of the created fistula. The subjects of the study were 79 newly born cattle and buffalo calves suffered from atresia coli, recti and ani. The calves were grouped into four groups for evaluation of incisional and herniation cecostomy techniques either on the right or left flank. With each technique, 4 cm diameter permanent fistula was created and evaluated at the 1^stweek, and 1^st, 4^th and 8^th months post-surgery. Both of the short and long-term complications were recorded and managed conservatively. Follow up could be achieved for 45 calves only and all of them showed stunted growth. The results revealed wider stoma in the calves operated by herniation technique, and in those operated on the right flank, moreover the operated cattle calves had wider stoma than buffalo calves. It is concluded that the right flank herniation technique has a beneficial effect on long-term preserving of a wider diameter of the created fistula.
