“…Regarding the easier detection of ovaries and uterus with lateral access compared to the median, we can note that after lateral laparotomy and displacement of the omentum, the uterus is under incision, while after ventral laparotomy it is covered by the intestine. This is also reported by McGrath et al, 2004;Arunkumar et al, 2017 andFerreira et al, 2015. Favorable conditions for the imposition of ligatures on the ovarian ligaments and uterus when operating through the lateral abdominal wall, in our opinion, are associated with the convenient location of our proposed surgical access. However, the amount of suture material that was used in this case was almost the same and did not depend on the location of the laparotomy.…”

Surgical access for ovariohysterectomy in bitches through the right lateral abdominal wall with an incision in its upper third in the direction from the anterior edge of the macula to the fourth nipple of the corresponding side of the breast is proposed. The article presents the results of studies obtained when used for the purpose of ovariohysterectomy in bitches of operative access through the right lateral and ventral abdominal wall. Research work was conducted on healthy mature bitches. The operations were performed in the area of the right lateral abdominal wall and in the umbilical region. On the lateral abdominal wall, an oblique-vertical incision was used at the border of the inguinal and iliac areas in the direction from the anterior edge of the macula to the fourth nipple of the corresponding side of the breast. The ventral abdominal wall was cut along the white line. It was found that when performing ovariohysterectomy in bitches using the proposed surgical access through the right lateral abdominal wall with a smaller wound size (P < 0.05), the duration of the operation and the healing period correspond to those when using median laparotomy. It is proved that operative access with oblique-vertical incision in the area of the right lateral abdominal wall at the border of the groin and anus during ovariohysterectomy in bitches provides favorable opportunities for surgical reception and closure of the surgical wound. The number of surgical sutures for sutures on the abdominal wall is less than in the case of ventral access (P < 0.01). It is also noted that in ovariohysterectomy in bitches, operative access through the right lateral abdominal wall with an incision in the direction from the anterior edge of the macula to the fourth nipple of the corresponding side of the breast may be recommended as an alternative access through the white line of the abdomen.

“…The principal original finding of this investigation was that the observed surgical times of the modified OSH technique were similar to other OSH studies in bitches [4,9]. The inverted OSH technique was quickly executed, similar to the TT, which is favorable since the higher occurrence of complications is related to a longer anesthesia time [11].…”

Background:The ovariosalpingohysterectomy (OSH) is one of the most performed surgeries in bitches often used in population control. Surgical techniques that decrease the chances of operative complications and cause less nociceptive stimulation and acute pain to the patient are highly sought after by veterinarians. We evaluated the inverted OSH technique (IT), which, after celiotomy, begins with the ligature execution, transection of the uterine body and subsequent ligation and ovarian disinsertion. The purpose of this investigation was to analyze aspects of IT execution in bitches, such as visceral manipulation, access to the uterus and ovaries, and surgical time compared to the traditional technique. Materials, Methods & Results:Inverted OSH was compared to the so-called traditional OSH technique, characterized by the initial removal of the ovaries followed by uterine section. The OSH techniques were performed in 24 healthy animals, with a body condition score of up to six (on a nine-point scale) in dogs aged between seven months and five years. All dogs were from the Birth Control Program of Dogs and Cats of the UFRRJ and were distributed into two groups: traditional technique (TT) and inverted technique (IT). Surgeries and anesthesia were carried out by the same veterinarian crew (surgeon, surgical assistant, and anesthesiologist). OSH techniques were evaluated by the surgeon and surgical assistant using semiquantitative analysis (multiple-choice questionnaire with closed questions that pointed scores related to the ease of uterine and ovarian manipulation, as well as to the level of manipulation of the intestinal and urinary vesicle) and qualitative descriptive methods (report of techniques with the opinion of surgeons and an external evaluator-veterinarian surgeon who attended surgeries). Also, the total surgical time and the indication of a positive analgesic response according to changes in the vital parameters observed by the anesthesiologist during specific moments of the operation were evaluated (traction of the ovarian pedicles and the uterine body). There was a greater intraoperative nociceptive stimulation in TT (five analgesic rescues and zero in IT) and greater ease of exposure, access, and manipulation of the ovaries in IT (right ovary P = 0.042 and left ovary P = 0.021); no difference in the manipulation of adjacent organs between groups (P = 0.944); with no statistical difference in total intraoperative time (P = 0.190). In the descriptive qualitative evaluation, inverted OSH revealed advantages concerning the ease of surgical access to the ovaries (especially the right ovary), particularly in heavier dogs. Discussion: The IT was considered easy to perform because the surgical team performed the two techniques at similar times despite having more experience and routine practice with the TT. The anatomy of the bitch challenges the performance of OSH during median celiotomy due to the dorsal location of the reproductive system in the abdominal cavity and, therefore, there is a need to manipulate t...

There are few studies evaluating the oxidant-antioxidant status after oophorosalpingohysterectomy (OSH) in female dogs. Here we determined the effect of OSH on antioxidant enzymes in serum, and quantified morphological changes in subcutaneous adipocytes. Lateral OSH was performed in 12 female dogs. The concentration of 17β-estradiol (17β-E 2 ), the activities of extracellular superoxide dismutase (SOD-ec), glutathione peroxidase (GPx), glutathione-S-transferase (GST) and glutathione reductase (GR) were determined. Glutathione (GSH), glutathione disulfide (GSSG), lipid peroxidation (LPO), total antioxidant capacity (TAC), carbonylation and vitamin C were measured in serum. Subcutaneous adipose tissue was obtained to determine morphological changes and cell number, under basal conditions and six months after OSH. The SOD-ec, GPx and GST activities increased significantly (p ≤ 0.05), LPO, carbonylation and GSSG also increased. GSH and vitamin C decreased (p = 0.03). 17β-E 2 tended to decrease six months after OSH. Hypertrophy of subcutaneous adipocytes was observed after OSH from the first month and was accentuated after six months (p = 0.001). The results suggest that 17β-E 2 decreases after OSH and alters the antioxidant enzyme activities in serum thus, redox balance is altered. These changes are associated with an increase in body weight and hypertrophy of subcutaneous adipose tissue.
