“…Similarly, the length of skin incision varies between 4 -9 cm (Freeman et al, 2014) and 9.6 ± 3.4 cm (Harris et al, 2013). In the present study, it was observed that total surgery time (58.50 ± 6.28 minutes) and length of skin incision (10.75 ± 1.40 cm) in the experiment group was consistent with the above mentioned studies.…”

“…It is known that the total surgery time of OVH performed by experienced veterinary surgeons is 17 minutes on average with 1.5 -2.5 cm width skin incision (Michelsen et al, 2012;Korkmaz et al, 2019). In contrast when students perform OVH, the duration of surgery time varies between 60 and 135 minutes, associated with the level of the students (Zeugschmidt et al, 2016) and the nature and type of teaching procedures such as how surgery is supervised (Bowlt et al, 2011;Harris et al, 2013;Freeman et al, 2014;Gates et al, 2018) and whether training includes tools such as virtual reality (Hunt et al, 2020), video recordings and plastic spay simulator models (Read et al, 2016;Shaver et al, 2019;Annandale et al, 2020). Similarly, the length of skin incision varies between 4 -9 cm (Freeman et al, 2014) and 9.6 ± 3.4 cm (Harris et al, 2013).…”

This study was designed to demonstrate the effects of surgical skills of final-year veterinary medicine students relating to total surgery time and skin incision length on postoperative stress, oxidative stress and pain in bitches undergoing ovariohysterectomy under identical anaesthesia and surgical procedures. The control group (n=12) consisted of bitches that were operated on by an experienced surgeon, while the ovariohysterectomies in the experiment group (n=12) were performed by final-year veterinary medicine students. Blood samples were taken 24 hours before the surgery, during premedication, at the end of surgery and 30 minutes, 1, 2, 4 and 6 hours after surgery for the analysis of cortisol, total oxidant status (TOS), total antioxidant status (TAS) and for the calculation of the oxidative stress index (OSI). Modified Melbourne Pain Scale was used for pain assessment. It was observed that the total surgery time and length of skin incision in the experiment group were significantly higher (p<0.001) than those detected in the control group. The concentrations of cortisol were statistically higher (p<0.001) in the experiment group than those measured in the control group, apart from the concentrations measured at 24 hours before surgery. The concentrations of TOS and TAS did not show any significant differences within and between groups. Similarly, OSI did not differ within groups. However, OSI values at premedication time in the experiment group were statistically higher (p<0.05) than those calculated in the control group. Pain scores did not differ within and between groups. In conclusion, it is indicated that the blood cortisol concentrations tend to increase due to the surgery time or the length of skin incision. Moreover, ovariohysterectomies may be safely performed by final-year veterinary medicine students without any postoperative pain.

“…Of the studies reviewed here only two major complications were reported, both by Harris et al (2013). Of these complications one, bladder laceration, would be expected to occur more commonly in OVH procedures due to the more caudal placement of the distal ligature.…”

In female dogs undergoing elective neutering is ovariectomy or ovariohysterectomy superior?

PICO question In female dogs undergoing elective neutering via midline coeliotomy is ovariectomy superior to ovariohysterectomy in terms of anaesthetic duration, incision length, complications and postoperative pain? Clinical bottom line Category of research question Treatment The number and type of study designs reviewed The number and type of study designs that were critically appraised were four prospective clinical trials (Peeters et al., 2011; Lee at al., 2013; Harris et al., 2013; and Tallant et al., 2016) and a retrospective cohort study (Okkens et al., 1997) Strength of evidence Critical appraisal of the selected papers meeting the inclusion criteria collectively provide weak evidence in terms of their experimental design and implementation Outcomes reported Okkens et al. (1997) found no occurrence of pyometra/endometritis in 135 dogs receiving ovariectomy (OVE) or ovariohysterectomy (OVH) over an 8–11 year follow-up period. This study also reported no significant difference in long-term postoperative complications in either group. Of the four prospective clinical trials one (Harris et al., 2013) had final year vet students perform the surgeries. This study found no difference in incision length, surgical time or incidence of intra-operative complications between techniques. However the relevance of this study to procedures performed by qualified veterinary surgeons is questionable. The remaining papers all evaluated incision length, surgical time and postoperative pain after surgeries performed by experienced vets. All three found mean incision length was shorter in the OVE group and two (Lee et al., 2013; and Tallant et al., 2016) found that surgical duration was shorter in the OVE group. Only one paper (Lee et al., 2013) revealed a significant difference in pain scoring between groups, with the OVE group having lower scores at 1, 2, 4 and 6 hours post-surgery. Lee at al. (2013) and Tallant et al. (2016) also recorded intra-operative complications, however none were noted in either group Conclusion In view of the strength of evidence and the outcomes from the studies the following conclusion is made; whilst the evidence does suggest OVE may be associated with some modest improvement in surgical time and incision length, due to the small sample sizes and varying techniques used, further studies are required before definitive conclusions can be made. There is currently insufficient evidence to determine if there is a difference in complication rates or postoperative pain between procedures. How to apply this evidence in practice The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources.

“…Laparoscopic neutering, in particular, is regularly used in a number of veterinary hospitals and is gaining greater acceptance and preference among veterinary practitioners. Most of the techniques currently used in small animal reproduction are for gonadectomies (ovariectomy in females, and cryptorchidectomy and vasectomy in males); however, ovariohysterectomy can readily be performed by laparoscopy if indicated (Dupré et al., ; Gower & Mayhew, ; Harris, Adams, Fordyce, & Ladlow, ; Milovancev & Townsend, ). New applications of endoscopic surgery, and where it has greatest potential to become the gold standard, in veterinary medicine will likely parallel the trends in human medicine (Khatuja et al., ).…”

Although endoscopic surgery entered its "golden era" in the mid-1980s, it is still advancing at a tremendous pace. Novel surgical techniques and devices are continuously developed and applied, and new indications (and/or contraindications) for the use of endoscopic surgery are routinely reported in the literature and subjected to systematic assessments. Although endoscopic surgery (laparoscopy in particular) has already become established as the gold standard in human medicine, it has yet to be proven as a viable alternative to open surgery in the field of veterinary medicine. The advantages of minimally invasive surgery include better intra-operative visualization, reduced postoperative pain, reduced scar formation and increased postoperative mobility. Therefore, it is reasonable to expect that the application of this will continue to expand. Small animal reproduction, a field within the broad discipline of veterinary medicine, has already recognized and begun to reap the benefits of endoscopic surgery. Herein, we retrospectively review the most recent successful novel applications of endoscopic surgery in the small animal reproduction system to provide small animal reproductive surgeons with important knowledge to help improve their own veterinarian medical practice.
