Information about the clinical significance of equine MDBs is currently limited.<\/jats:p>\n <\/jats:sec>\n \n Objectives<\/jats:title>\n To report the clinical features, surgical findings and outcomes of horses undergoing exploratory laparotomy where a MDB was identified.<\/jats:p>\n <\/jats:sec>\n \n Study design<\/jats:title>\n Retrospective case series.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n Case records of horses undergoing exploratory laparotomy for colic over a 14\u2010year period (2009\u20132022) were reviewed. MDBs identified at laparotomy were classified as the primary or contributory cause of abdominal pain, or as incidental.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n MDBs were identified in 40\/1943 horses (2.1%) and 15 were primary (32.5%), 10 contributory (25%) and 15 incidental (32.5%). Horses with primary MDBs (median 2\u2009years, IQR 1\u201312) were significantly younger than horses with incidental MDBs (median 8\u2009years, IQR 6\u201316;\n P<\/jats:italic>\n \u2009=\u20090.01). MDBs were more likely to be incidental if located in the mid\u2010jejunum (5\/5) (\n P<\/jats:italic>\n \u2009<\u20090.001) or where a mesenteric pocket was absent (11\/15) (\n P<\/jats:italic>\n \u2009=\u20090.01). Primary MDBs caused extra\u2010mural obstruction due to mesenteric shortening (\n n<\/jats:italic>\n \u2009=\u20094), small intestinal entrapment within the MDB pocket (\n n<\/jats:italic>\n \u2009=\u20095) or in an adjacent mesenteric rent (\n n<\/jats:italic>\n \u2009=\u20094), and volvulus around the MDB (\n n<\/jats:italic>\n \u2009=\u20092), with intestinal resection required in 8\/15 cases. For horses with primary MDBs, survival to hospital discharge was 60% overall (9\/15) and 75% for horses that stood following anaesthesia (9\/12) with 88.9% of cases discharged from hospital (8\/9) surviving >1\u2009year. Excision of MDB tissue was not associated with complications but 3\/4 non\u2010incidental MDBs left in situ required relaparotomy to treat MDB\u2010associated colic.\n <\/jats:p>\n <\/jats:sec>\n \n Main limitations<\/jats:title>\n Retrospective single centre data.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Most MDBs in horses undergoing surgical treatment of colic in this population were not incidental. MDB\u2010associated colic was most commonly classified as strangulating obstruction, but non\u2010strangulating extra\u2010mural compression was also identified. Excision of MDB tissue should be undertaken where possible, particularly in non\u2010incidental cases.<\/jats:p>\n
