“…Although in a study in bitches [10], and in one with cats [12], reported greater surgical time for haemostasis using suture thread than bipolar electrocoagulation or clips, the mean surgical time in the present study was lower than those reported by these authors. Furthermore, the surgical time from this study is similar to that of other studies in cats in which haemostasis of the OAVC was achieved using bipolar electrocoagulation [5,17,18].…”

“…Although pneumoperitoneum pressure of 10 mmHg has been previously recommended [12,17], the 4 mmHg pressure used in this study enabled excellent visualization and manipulation of the organs, similarly to previous reports [5,7,18]. It is known that the greater the intra-abdominal pressure, the greater the CO 2 absorption by the peritoneum and, consequently, the greater the cardiorespiratory alterations observed [13].…”

“…Some of the complications reported in the trans-operative period of laparoscopic OVH and OVE are haemorrhage, organ lacerations by the trocar, subcutaneous emphysema, and the need to convert to open surgery. At the post-operative period, the complications often observed are haematomas, discharge at the site of skin suture, infection, suture dehiscence, and incisional hernia [3,5,17]. In the present study, complications were observed in only one animal (incisional hernia).…”

“…Haemorrhage of the ovarian pedicle and uterine blood vessels are very common complications during the trans-operative period [17]. Only in one female there was minimal haemorrhage after sectioning of the OAVC suture thread; however, there was no need for intervention and no post-operative complications were present.…”

Background: Ovariectomy(OVE) and ovariohysterectomy (OVH) are the most performed surgical procedures in Veterinary Medicine. In videosurgery, both in stray animals at sterilization campaigns and in the increasing demand of tutors to perform the technique. Laparoscopy results in reduced tissue damage, due to minimal organ manipulation and surgical access hemostasis can be performed by several methods, such as electro-coagulation, clips, and intra and extracorporeal ligatures. A pre-tied ligature system, or endoloop, is a haemostatic technique comprised of a slipknot and knot pusher, which is inserted into the abdominal cavity through one of the laparoscopic ports. The aim of this study was to describe a novel OVE technique in cats, in which haemostasis was performed using miniloop, aimed at reducing the number of ports needed for knot tying.Material, Methods & Results: Ten healthy not spayed female cats, aged 6 months to 5 years, were selected for this study. They were submitted to an OVE using miniloop as haemostasis method. Access to the peritoneal cavity was through two 5 mm ports on the midline of the ventral abdomen, 5 cm apart, with one immediately caudal to the umbilical scar and the other in between the last pair of teats. The first trocar was inserted at the caudal incision using the Hasson technique and a 5 mm zero-degree optics attached to a camera was introduced through it. The placement of the second access port was video assisted. For ovary exposure, the patients were positioned in lateral recumbency on the contralateral side to the ovary being removed. The miniloop was composed of a 2 mm diameter minitrocar, a 1.8 mm knot pusher, and a pre-tied slipknot. It was introduced percutaneously at the lateral abdominal wall. It was inserted attached to a pre-tied loop ligature. A Babcock forceps was used to guide the slipknot until it enveloped the ovarian vessels and the proximal part of the uterine horn. Subsequently, the knot was tightened with the aid of the knot pusher. A second miniligature was applied. The forceps was removed and a Metzenbaum scissors inserted to cut between the ligatures, releasing the ovary with the nylon ligature but keeping the PDS knot. It was performed at both ovary. Mean (±SD) surgical time was 44.8 min (± 13.4) and varied significantly (P = 0.0006) between animals, with the shortest time being 29 min and the longest 66 min. Positioning of the patients in lateral decubitus allowed for good ovarian exposure, without the need for excessive manipulation of the intestinal loops or other abdominal organs. Rupture of the suture thread was the only trans-operative complication observed and occurred in two animals. A second ligature (miniloop) was needed to ensure haemostasis. One cat showed eventration at the site of the caudal port on the second day post-operative.Discussion: The mean surgical time in the present study was lower than reported by some authors, but longer than anothers. Furthermore, the surgical time from this study is similar to that of other studies in cats in which haemostasis of the OAVC was achieved using bipolar electrocoagulation. Surgical team expertise is of outmost importance in minimizing complications and overcoming problems during videosurgical procedures in order to reduce surgical time, such as gas leakage, extensive incision, and difficulty in manipulating surgical instruments.

“…Isso se deve ao avanço tecnológico de instrumentos adequados e modernos, e também maior capacitação técnica dos cirurgiões. Contudo, algumas alterações fisiológicas deletérias podem ocorrer devido a necessidade de criação de um espaço intra-abdominal caracterizado pelo pneumoperitônio (FERREIRA et al, 2013;TAVARES et al, 2016).…”

Laparoscopic procedures require the creation of pneumoperitoneum. CO2, which must be cold and dry, is the standard gas used in such surgeries. The type of gas used, its temperature, and moisture may change the peritoneal surface and cause systemic and local oxidative stress. Our objective is to evaluate the influence of pneumoperitoneum heating on the occurrence of histological lesions in the peritoneum, inflammation, plasma oxidative stress, and on the mesothelial surface in patients undergoing video-assisted ovariohysterectomy. Twenty canine females were included and distributed evenly into two groups: heated CO2 (HG) and unheated CO2 (UHG). The biomarkers of inflammation and oxidative stress were evaluated before insufflation (T0), at 30 min (T1), and at 60 min (T2) of exposure to CO2. Biopsies of the peritoneal tissue for histological evaluation were performed at T0 and T2. Regarding plasma parameters, acetylcholinesterase (AChE) showed a greater activity in the HG at T1 ( p = 0.0268 ) and T2 ( p = 0.0423 ); in turn, butyrylcholinesterase (BChE) showed a greater activity at T2 in the HG ( p = 0.0175 ) compared with T0. Catalase activity (CAT) was different between HG times; it was higher at T1 ( p = 0.0253 ). There was a decrease in the levels of substances reactive to thiobarbituric acid (TBARS) ( p = 0.0117 ) and in glutathione (GSH) ( p = 0.0114 ) between T0 and T2 in the UHG. Regarding tissue oxidative stress, the CAT in the HG showed a greater activity at T2 than T1 ( p = 0.0150 ). By comparing the groups at each time, there was a difference only at T2 ( p = 0.0288 ), being greater in the HG. Regarding the activity of superoxide dismutase (SOD) in the HG, there was a difference between T2 in relation to T0 and T1 ( p = 0.0181 ); finally, there was an increase only at T1 ( p = 0.0287 ) in the UHG when comparing groups at the same time. There were no differences in the histological parameters evaluated. Our study demonstrates that the heating of CO2 generates a greater inflammatory response and forms reactive oxygen species (ROS) at the plasma and peritoneal levels.
