Ovarian remnant syndrome (ORS) is a condition resulting from incomplete removal of ovarian tissue during ovariectomy and/or ovariohysterectomy. Single-port laparoscopy (SPL) is an alternative to ventral midline laparotomy for treatment of ORS. Medical records of 13 client-owned female dogs who underwent SPL for the treatment of ORS were retrospectively reviewed to evaluate surgical technique and outcome. Dogs who had undergone a previous attempt at open ovariectomy or ovariohysterectomy were included. Major intraoperative complications did not occur and conversion to open laparotomy was not required. In 1 dog, an SPL + 1 technique was used, in which an additional port was placed cranial to the single-port device to aid in dissection and tissue manipulation. Median surgical time was 45 min (range, 30-90 min). Clinical signs related to estrus had resolved in 11 of 13 dogs with a median follow-up time of 18 mo. Two of 13 dogs were lost to follow-up at 3 mo postoperatively; however, signs of estrus had resolved at time of last follow-up. SPL treatment for ORS was feasible and successful in this cohort of dogs. Reduced surgical time was found in this study compared with previous reports investigating multiple-port laparoscopic treatment of ORS.
