occlusion caused by the port itself. At this stage, peristalsis,that cannot push the luminal content aborally, will insteadpull the intestinal segment orally. This can eventually lead tothe exit of the proximal intestine until the luminal content inthe herniated portion will block this progression. Distally, beingthe intestine empty, it is easily and progressively brought intothe hernia. This progression ends only when the ileum isinvolved and traction on the ileocaecal valve prevents thisphenomenon.Conclusions: This hypothesis can explain why the ileum isinvolved in the majority of cases of internal hernias.Eventually, antiperistaltic drugs administered early in thecourse of the disease, may reduce the length of intestineaffected.Ethical animal research: No ethical approval required.Source of funding: None.Competing interests: None.95STANDARDISATION OF CRITICAL DECISIONS AND COSTSTO REDUCE EUTHANASIA IN COLIC SURGERY. A SINGLE-CENTRE PROSPECTIVE STUDY IN ITALYGandini M. and Giusto G.Department of Veterinary Sciences, University of Turin, L.goPaolo Braccini 2-5, Grugliasco (TO), Italy.Email: marco.gandini@unito.itBackground: Pre- or intra-operative euthanasia is oftenchosen for financial constraints or presumed poor prognosis.This can reduce the total number of horses potentially savedwith colic surgery, despite the actual condition of the horse.Objectives: To reduce pre- and intra-operative euthanasia ofcolic cases due to financial constraints and presumptive‘poor prognosis’.Methods: For cases admitted for colic surgery, a standardprotocol for critical decisions was used. To eliminate thefinancial factors, owners were offered a standard range ofprice for colic surgery, regardless of the eventual need forresection and anastomosis.Results: Price quotation for colic surgery was 4800-5800 eurosand was well accepted by owners and sustainable by thehospital. Two-hundred and eleven cases were admitted (66medical, 145 surgical). Consent to surgery was given in 132/145 horses. Euthanasia for decision of the surgeon were 2/132before surgery (viscera rupture), and 8/130 intraoperatively (5because of viscera rupture, 2 for excessive length of necroticsmall intestine, 1 for unresectable large colon). Two horsesdied during anaesthesia and 4 were euthanised in therecovery stall. This led to 115 horses that stood afteranaesthesia. Twelve horses were euthanised because of post-operative complications. Seventy-nine percent of operatedand 89.5% of recovered horses were discharged from thehospital.Conclusions: Standardisation of procedures and costs resultedsustainable, while reducing biases due to the surgeon choiceor owner decision, and with survival rates comparable toother studies. One of the main causes of death was theowner not giving consent to surgery.Ethical animal research: No ethical approval required.Source of funding: None.Competing interests: None.96CLINICAL COMPARISON BETWEEN A SKIN-STAPLED ANDA CONTINUOUS LEMBERT PATTERN FOR JEJUNOJEJUNALEND-TO-END ANASTOMOSIS IN HORSESGiusto G. and Gandini M.Department of Veterinary Sciences, University of Turin, L.goPaolo Braccini 2-5, Grugliasco (TO), Italy.Email: gessica.giusto@unito.itBackground: One-layer jejunojejunal anastomosis isconsidered effective in horses. Several patterns have beenproposed but rarely compared clinically.Objectives: The objective of the study was to compareoutcome and complications of a modified skin stapled and acontinuous Lembert pattern in jejunojejunal anastomosis inhorsesMethods: Data from clinical records of 24 horses thatunderwent jejunojejunostomy between January 2018 andJanuary 2021 at the University of Turin VTH were retrieved.Short-term complications, short- and long-term survival (>9months) were compared after a modified skin stapled (12horses with strangulating lesions, 1 with non-strangulatinglesion), and a continuous Lembert pattern (10 horses withstrangulating lesions, 1 with non-strangulating lesion).Results: Post-operative reflux (POR) developed in 9 horses, 6with the continuous Lembert and 3 with the skin stapledanastomosis. POR in the continuous Lembert group wascaused by obstructive adhesions found at necropsy (2cases), obstruction of the anastomotic site confirmed atrelaparotomy (1 case). In the skin stapled group, one of thehorses that developed POR was found having obstructiveadhesions at necropsy but not involving the anastomosis.Short-term survival was 85% (11/13) for skin stapledanastomosis, and 72% (8/11) for the continuous Lembertpattern. Long-term survival (>9 months) was 100% for skinstapled anastomosis, and 90.9% for continuous Lembertpattern.Conclusions: Both patterns performed well in clinical use,although the Lembert continuous pattern has a higher risk ofdeveloping POR.Ethical animal research: No ethical approval required.Source of funding: None.Competing interests: None.97EX VIVO COMPARISON OF LIGATURES ANDHAEMOSTATIC CLIPS FOR MESENTERIC VESSELSOCCLUSION IN SMALL INTESTINAL RESECTION ANDANASTOMOSISGiusto G., Guercilena C. and Gandini M.Department of Veterinary Sciences, University of Turin, L.goPaolo Braccini 2-5, Grugliasco (TO), ItalyEmail: gessica.giusto@unito.itBackground: In equine abdominal surgery extensive resectionand anastomosis of small intestine is a commonly performedprocedure. To provide haemostasis, absorbable ligatures,surgical staplers and vessel sealing devices have beenproposed in horses.© 2021 The Authors. Equine Veterinary Education © 2021 EVJ LtdAbstracts 49
