- چکیده:
- چکیده انگلیسی: Ovariectomy (OVE) is a routine surgical procedure for neutering in small animal practice. Laparoscopy is a new surgical technique which contains advantages such as less trauma, smaller incision and excellent visualization than traditional open surgery. The present study was conducted to examine the feasibility and safety of laparoscopic procedure through two portal comparing with the conventional open surgery for OVE in healthy female bitches (n=16). Dogs were divided in two equal groups. In laparoscopic group, two 5 and 10 mm portals were inserted; First in the umbilicus for introducing the camera and the second, caudal to the umbilicus for inserting the forceps. Laparoscopic procedure involved grasping and tacking the ovary to the abdominal wall, followed by electrocautery, resection and removal of the ovary. In open surgery, routine OVE was conducted through an incision from umbilicus to caudal midline. Mean operative time, total length of scar, blood loss, clinical and blood parameters and all intra and post-operative complications were recorded in both groups. Mean operative time, total length of scar, blood loss and post-operative adhesions were significantly less in laparoscopic group compared with open surgery. In conclusion, laparoscopic OVE is an acceptable procedure due to more advantages in comparison with traditional OVE.

- چکیده:
- چکیده انگلیسی: Objective- Laparoscopic partial nephrectomy (LPN) has been proven to be a safe and effective technique in human. This study was conducted to evaluate the feasibility and safety of utilizing laparoscopic partial nephrectomy in dogs and to compare this technique with open routine partial nephrectomy for the first time in Iran.
Design- Experimental study.
Animals- Sixteen large mixed-breed female dogs, weighting 22±5 kg, 1-2 years age.
Procedures- All dogs were anesthetized and positioned for surgery on left kidney. Partial nephrectomy (PN) was performed through five portals in left flank in laparoscopic group and through midline incision in open group. After renal artery was recognized and clamped, the caudal pole of kidney was resected. Then the exposed renal parenchyma was sutured. Operative time, ischemia time, incision length, clinical findings, hematological parameters, blood urea nitrogen, serum creatinine and intra and post-operative complications were recorded for one month.
Results- Surgeries were performed successfully in both groups and visualization was excellent in laparoscopic group. Mean operative time was insignificantly longer in laparoscopic group. Mean ischemia time was evaluated more in laparoscopic group but total length of incisional scar was obviously longer in open cases. There was mild infection in one portal site of first group. Other parameters were assessed normal and there was no significant complication in both groups.
Conclusion and Clinical Relevance- This experience demonstrated that LPN is a safe and feasible procedure in dogs with acceptable outcomes and advantages comparing with open PN.

- چکیده:
- چکیده انگلیسی: Objective- Comparative endoscopic evaluation of two reconstructive methods (R&Y and jejunal loop interposition) after gastrectomy in dogs. Design- Experimental study. Animals- Ten healthy male dogs. Procedures- The animals were divided randomly in two groups. After a 12 hour food withhold and under general anesthesia laparotomy is performed in all dogs. In group A (R&Y), after dissection and resection of all gastric vessels and ligaments, the stomach was resected cranially close to cardia and caudally close to pylorus. After gastrectomy duodenal end was closed in a two layer inverting suture pattern. Then a loop of jejunum 20 cm distal to Treitz ligament was identified and resected. End to side anastomosis was performed between the distal jejunal end and remained part of the stomach. The proximal jejunal end was end to side anastomosed to the rest of jejunum. In group B (JLI), gastrectomy was done in the same manner. The 20 cm length of jejunum was resected from a 20 cm distance to Treitz ligament. The proximal end of the jejunal loop was end to side anastomosed to the remained part of the stomach and the distal end was anastomosed to the proximal jejunum. Finally jejunojejunostomy was performed between the two Jejunal parts. 1 month after surgery, esophagoscopic and gastroscopic evaluation was performed to rule out the reflux esophagitis or gastritis. Results- Esophagoscopy and gastroscopy thirty days after operation revealed normal appearance at gastroduodenal and duodenojejunal anastomotic junctions. There was no report of enterogastric biliary reflux (EBR) in esophagus or alkaline gastritis. A 2 cm to 2 cm ulcerative mass was observed in the remained part of stomach close to gastrojejunal anastomotic site in one patient in group A. Also regurgitation was noticed in the same patient. A 1 cm to 1 cm ulcer was reported in one patient in group B. Morphology of all anastomotic sites was normal. They were all patent and healed normally without any signs of inflammation. Conclusion and Clinical Relevance- The results of this study showed that the JLI like R&Y technique is a successful method to prevent reflux esophagitis.

- چکیده:
- چکیده انگلیسی: Objective- To study the effects of Isoflurane in inducing anesthesia and comparing mask and chamber induction anesthesia in rabbits for the first trial in Iran. Design- Experimental design. Animals- 20 female adult New Zealand White rabbits. Procedures- Animals were divided randomly into two groups. A 40 cm3 Chamber was used in group A with 4-5% concentration of isoflurane and a face mask was used in group B with 1-1.5% concentration of isoflurane to induce anesthesia. The concentration of isoflurane increased in 30 second intervals since reached to 4%. Routine ovariohysterectomy was performed in both groups. Duration of induction and recovery, apneuastic period and volume of consumed isoflurane were measured in both groups. Results- Mean duration of induction of anesthesia was significantly shorter in group B in comparison to group A (P<0.05). Apneuastic duration was lasting 10 to 90 sec. The volume of isoflurane delivered to animals was significantly lower in group B (7.1±1.2 ml) compared with group A (24.7±6.6 ml) (P<0.05). The mean duration of recovery was not significantly different in group A compared to group B (P>0.05). Conclusion and Clinical Relevance- As concluded use of isoflurane to induce anesthesia in rabbits is feasible and safe in case of available equipments. Mask induction seems more appropriate to induce anesthesia than chamber.

- چکیده انگلیسی: Objective-comparative evaluation of different surgical methods of vesicoureteral reflux induction in rabbits. Design- Elective experimental study. Animals- sixteen healthy male rabbits. Procedures- sixteen healthy New Zealand White male rabbits were randomly divided in four equal groups. All rabbits were preoperatively evaluated with retrograde cystography for the presence or absence of congenital or acquired vesicoureteral reflux. Rabbits of group1 (control) without any manipulation were kept for comparing with other three experimental groups. Rabbits of group 2, 3 and 4 undergone open surgeries with unroofing the ureter with surgical blade incision of 3-5mm in length. In group two incised ureter left without suturing ureteral mucosa, in group three incised ureter sutured with nylon material 5-0 and in group four ureter was incised with electrosurgical cutting blade without suturing mucosal layer to the bladder roof. Postoperatively on days 7th, 15th and 30th all animals in different groups undergone cystography for presence or absence of vesicoureteral reflux. Results- All the animals of group 1, 2 and 4 didn't show any reflux in double contrast cystography but in group 3 reflux in the form of bilateral and unilateral were observed clearly. Conclusion and Clinical Relevance- Unroofing the ureter with surgical blade incision and suturing the incised margins can induce the successful vesicoureteral reflux for undergoing an experimental study of vesicoureteral reflux treatment.

- چکیده انگلیسی: Objectives- To evaluate radiographic changes and macroscopic findings in handsewn laparoscopic gastrojejunostomy in dogs. Study Design-Elective experimental study Animals-Eighteen mix-breed healthy male and female dogs. Methods-Animals were divided in two equal groups randomly. Two layers handsewn laparoscopic side to side gastrojejunostomy was performed in the control group and one layer in the treatment group. Cases were monitored for four weeks. Contrast radiographs were taken in the first and last week of the study. Cases were sacrificed after four weeks and macroscopic findings were evaluated at the anastomotic site and it’s diameter was measured. Results-There was no evidence of stricture, stenosis or organ displacement radiographically. No infection, stricture, fistulae formation, abscess, ischemia or gross granulation tissue was seen, but several adhesions were found in the abdominal cavity macroscopically. The most frequent adhesion was between omentum and the anastomotic site which was reported in all cases. There were no statistically significant difference between the anastomotic diameter in both groups (P>0.05). Conclusion and clinical relevance- One layer laparoscopic handsewn gastrojejunostomy is a safe and feasible technique without serious complication with no statistically significant difference with the conventional two-layer technique.
