Methods: Between May and December 2008, 10 horses (3 geldings, 2 stallions, 5 mares), aged 4 to 18 years, admitted because of recurrent LDDLC were treated after resolution of the displacement, by laparoscopic closure of the nephrosplenic space. Horses, were restrained standing in stocks, sedated with detomidine (0,02 mg/kg IV in 1 It 0.9% NaCl infusion). Several portal sites in the left paralumbar fossa were infiltrated with 2% mepivacaine.

LDDLC recurrence did not occur in any horse. Discussion and conclusions: Our results suggest that laparoscopic closure of the nephrosplenic space will prevent recurrence of LDDLC. All 10 horses had good cosmetic outcome and there were no recognized signs of pain associated with this kind of surgery.

Abstract

Introduction: Entrapment of the ascending (large) colon within the nephrosplenic space, also called left dorsal displacement of the large colon (LDDLC) occurs commonly in horses. Depending on the severity of the colic, differing approaches to correction of LDDLC have been recommended and include medical treatment, rolling the horse under general anesthesia or surgical correction. The reported recurrence rate for nephrosplenic entrapment is up to 8.1%. To prevent recurrence, colopexy, partial colon resection, surgical closure of the nephrosplenic space under general anesthesia or in standing horses including by laparoscopy have been described. Objectives: To report our experience with, and outcome after, laparoscopic closure of the nephrosplenic space in horses with recurrent LDDLC. Number of recurrent events and interval between events were evaluated before and after surgery. Methods: Between May and December 2008, 10 horses (3 geldings, 2 stallions, 5 mares), aged 4 to 18 years, admitted because of recurrent LDDLC were treated after resolution of the displacement, by laparoscopic closure of the nephrosplenic space. Horses, were restrained standing in stocks, sedated with detomidine (0,02 mg/kg IV in 1 It 0.9% NaCl infusion). Several portal sites in the left paralumbar fossa were infiltrated with 2% mepivacaine. Closure of the nephrosplenic space was accomplished by apposing the dorsomedial splenic capsule to the dorsal portion of the nephrosplenic ligament with 0 polyglyconate in a continuous pattern. Follow-up information was obtained by telephone interview of owners. Results: Mean time for laparoscopic surgery was 55 minutes and closure of nephrosplenic space was successful without intraoperative or postoperative complications. LDDLC recurrence did not occur in any horse. Discussion and conclusions: Our results suggest that laparoscopic closure of the nephrosplenic space will prevent recurrence of LDDLC. All 10 horses had good cosmetic outcome and there were no recognized signs of pain associated with this kind of surgery.
