“…The technique described by Silva et al (2011) was used, except for the hemostasis of the uterine body and vessels, which was carried out using bipolar coagulation and cut instead of ligation with suture thread. The incision was closed in two layers using 0-USP polyglecaprone 25 thread, cross mattress pattern on the linea alba, and 3-0 USP nylon, interrupted horizontal mattress suture on the skin.…”

“…Laparoscopic and laparoscopic-assisted OVH were described using four port (Brun et al, 2000;Malm et al, 2004), three (Mayhew and Borown, 2007), two port (Dupré et al, 2009) and singleport approach (Dupré et al, 2009;Silva et al, 2011). Natural orifice transluminal endoscopic surgery (NOTES) is one of the newest concepts in minimally invasive surgery that brings promising results over conventional and other endosurgical spay techniques (Freeman et al, 2009;Brun et al, 2011).…”

The recently developed minimally invasive techniques of ovariohysterectomy (OVH) have been studied in dogs in order to optimize their benefits and decrease risks to the patients. The purpose of this study was to compare surgical time, complications and technical difficulties of transvaginal total-NOTES, singleport laparoscopic-assisted and conventional OVH in bitches. Twelve bitches were submitted to total-NOTES (NOTES group), while 13 underwent single-port laparoscopic-assisted (SPLA group) and 15 were submitted to conventional OVH (OPEN group). Intra-operative period was divided into 7 stages: (1) access to abdominal cavity; (2) pneumoperitoneum; approach to the right (3) and left (4) ovarian pedicle and uterine body (5); (6) abdominal or vaginal synthesis, performed in 6 out of 12 patients of NOTES; (7) inoperative time. Overall and stages operative times, intra and postoperative complications and technical difficulties were compared among groups. Mean overall surgical time in NOTES (25.7±6.8 minutes) and SPLA (23.1±4.0 minutes) groups were shorter than in the OPEN group (34.0±6.4 minutes) (P<0.05). The intraoperative stage that required the longest time was the approach to the uterine body in the NOTES group and abdominal and cutaneous sutures in the OPEN group. There was no difference regarding the rates of complications. Major complications included postoperative bleeding requiring reoperation in a bitch in the OPEN group, while minor complications included mild vaginal discharge in four patients in the NOTES group and seroma in three bitches in the SPLA group. In conclusion, total-NOTES and SPLA OVH were less time-consuming then conventional OVH in bitches. All techniques presented complications, which were properly managed.Keywords: canine, spay, laparoscopy, operative time, transvaginal approach Palavras-chave: caninos, castração, laparoscopia, tempo operatório, abordagem transvaginal RESUMO O emprego de novas técnicas minimamente invasivas de ovário-histerectomia (OHE) vem sendo estudado em cães com o intuito de otimizar seus benefícios e reduzir os riscos aos pacientes. O presente estudo objetivou comparar o tempo cirúrgico, as complicações e dificuldades técnicas entre as abordagens por total-NOTES transvaginal, videoassistida com único portal e por celiotomia para ovário-histerectomia (OVH) em cadelas. Foram operados 12 animais por total-NOTES (grupo NOTES), 13 pela técnica videoassistida (grupo SPLA) e 15 pela técnica convencional (grupo OPEN

“…The high value for surgical time found in our study may have occurred due to the surgical team's short learning curve on such surgical technique. Depending on the technique, a minimum of 20 surgical procedures are required in order to achieve proficiency (SILVA et al, 2011).…”

“…Although, considered minimally invasive and of short time achievement, SPLA and LESS OVH present peculiar and challenging technical issues, such as lack of instrument triangulation. Those issues are particularly difficult even for experienced surgeons (GOWER & MAYHEW, 2008;SILVA et al, 2011). Few studies regarding learning curve of laparoscopic or lap-assisted OVH were carried out on feline specie (TAVARES et al, 2016).…”

The purpose of this study was to assess the use of a homemade multiport for LESS (laparoendoscopic single-site surgery) ovariohysterectomy (OVH) in cats. Intra and postoperative variables of the surgery steps, technical challenges, complications and evolution of surgical time by a surgeon in training were evaluated. Twenty queens were selected for LESS OVH. The multiport device was manufactured of a conical-shaped ethylene polytereftalate (PET) bottle, urethral catheter no. 8, latex balloon no. 11, a 3.5mm and a 6mm laparoscopic trocars. Hemostasis was carried out using bipolar diathermy. Mean total surgical time was 14.54±5.12 minutes. Approach to right and left ovarian pedicles and abdominal access for insertion of the multiport device were the most time consuming surgical steps. LESS ovariohysterectomy using a new homemade multiport device is feasible and safe. Thus, the proposed technique may be considered as a minimally invasive alternative to ovariohysterectomy in the feline specie.
