Plain-English summary
A group of 33 dogs underwent either a laparoscopic-assisted ovary-sparing spay (LapOSS) or a laparoscopic ovariectomy (LapOVE) to evaluate the risk of developing pyometra, a serious infection of the uterus. None of the dogs that had the LapOSS procedure developed pyometra, and the surgery was found to be a safe option for sterilization. However, some dogs did develop tumors later on, but this was not directly linked to the type of surgery they had. Overall, LapOSS appears to be a reliable choice for dog owners considering sterilization without increasing the risk of this particular infection.

Abstract
OBJECTIVE: To evaluate incidences of pyometra and orthopedic, behavioral, urinary/reproductive, neoplastic, or atopic disease processes as outcomes for dogs undergoing either a laparoscopic-assisted ovary-sparing spay/hysterectomy (LapOSS) or a laparoscopic ovariectomy (LapOVE). ANIMALS: 33 client-owned dogs. PROCEDURES: Medical records of client-owned dogs presenting between August 2013 and May 2020 for elective LapOSS or LapOVE were reviewed. A multiple-choice client questionnaire was emailed to all clients whose dogs' complete medical records were available. RESULTS: 17 of the 33 dogs were in the LapOSS group, and 16 of 33 dogs were in the LapOVE group. Of the 17 dogs undergoing LapOSS, 5 of 17 (29%) underwent an elective OVE at a later date. The mean follow-up time was 4.2 ± 1.8 years for the LapOSS group and 4.3 ± 2.0 years for the LapOVE group. No dogs developed stump pyometra. One LapOSS dog developed mammary tumor, and 2 others developed nonreproductive malignant neoplasia while 2 of the LapOVE dogs developed malignant neoplasia. One of the LapOSS dogs with malignant neoplasia had an ovariectomy prior to development of disease. CLINICAL RELEVANCE: Laparoscopic-assisted ovary-sparing spay appears to provide a safe and reliable method of sterilization, with no observable increased risk of pyometra with hysterectomy. Owners must be counseled prior to surgery regarding the consequences of gonadal hormone retention and multiple heat cycles.
