Clinical features and outcome of 40 horses with mesodiverticular bands identified during exploratory laparotomy for management of acute colic.

Most MDBs in horses undergoing surgical treatment of colic in this population were not incidental. MDB-associated colic was most commonly classified as strangulating obstruction, but non-strangulating extra-mural compression was also identified. Excision of MDB tissue should be undertaken where possible, particularly in non-incidental cases.
