A Comparison of Laparoscopic and Belt-Loop Gastropexy in Dogs
Veterinary Surgery, 1996
A simplified technique for laparoscopic gastropexy (group 1) was compared to belt-loop gastropexy (group 2) in eight adult male dogs randomly divided into two groups of four dogs each. Our hypothesis was that a satisfactory laparoscopic gastropexy would approximate the strength and operative time required for belt-loop gastropexy. Operative time, surgical complications, postoperative morbidity, gross and histological appearance, radiographic microvascularization, and maximal tensile strength were measured and compared between the two groups. All dogs recovered from surgery. No morbidity was associated with either procedure. The mean (2SD) duration of surgery was 69.75 2 7.23 minutes for group 1 and 58.75 % 7.63 minutes for group 2. Fifty days after surgery, the microvascular appearance of the gastropexy site was similar for both groups. Blood vessels were observed within each seromuscular flap but vascular ingrowth to the abdominal musculature was observed in only two dogs, one from each group. The maximum tensile strength at 50 days was 76.55 2 22.78 for group I and 109.21 2 22.29 N for group 2. Differences between surgical duration and maximum tensile strength were not statistically significant ( P > .05). Histologically, all gastropexies consisted of an adhesion composed of dense fibrous connective tissue. The results of this study indicate that laparoscopic gastropexy provides a minimally invasive alternative to open abdominal prophylactic gastropexy in dogs.
A Laparoscopic-Sutured Gastropexy Technique In Dogs: Mechanical and Functional Evaluation
Veterinary Surgery, 2000
To describe a laparoscopic-sutured gastropexy technique in dogs and evaluate the tensile strength of the adhesion and effects on gastric function. Experimental study. Female beagle dogs (n=7). A laparoscopic-sutured gastropexy technique was evaluated by ex vivo tensile distraction tests 10 weeks after surgery. The effect of the adhesion on gastric emptying, mucosal permeability, and systemic inflammation were evaluated by monitoring the C-reactive protein (CRP) and sucrose permeability, and by radiographic evaluation of gastric emptying 2 weeks before and 10 weeks after surgery. Mean (+/-SD) tensile force to disrupt adhesions was 51.1+/-16.4 N. There was no significant postoperative increase in CRP concentration or change in sucrose permeability. The area under the curve representing the postprandial decrease in gastric radiographic area increased by 11% after gastropexy. This laparoscopic gastropexy technique had appropriate mechanical and functional characteristics with limited morbidity. This laparoscopic-sutured gastropexy provides adhesion strength comparable with other gastropexy techniques tested at 10 weeks postoperatively. Only minor changes in gastric emptying were observed 10 weeks after surgery.

The laparotomy surgical procedure allows for the identification and correction of intestinal lesions associated with acute abdomen in horses. The clinician relies on various laparotomy techniques to diagnose and treat this syndrome, and to date, the postsurgical effects of these techniques have not been clarified. The aim of this study was to evaluate the effects of jejunal manipulation during three laparotomy techniques through physical and clinical parameters and echography. Fifteen healthy horses were randomly assigned to three groups: animals in G 1 (n ¼ 5) were subjected to an exploratory laparotomy, animals in G 2 (n ¼ 5) to a laparotomy with an enterotomy, and animals in G 3 (n ¼ 5) to a laparotomy with an enterectomy. Degree of pain, jejunal wall thickness, and clinical parameters were evaluated before and after surgery. Horses in G 3 had higher heart rates, respiratory frequency, degree of pain, and jejunal wall thickness compared with G 1. Clinical variables during the postsurgical period were compared among the laparotomy techniques, and higher values of erythrocytes, leucocytes, neutrophils, and proteins were found in horses belonging to G 3 compared to those in G 1. Intestinal manipulation during the surgical procedure altered the physical and clinical parameters, as well as the results of the echography evaluation, with more significant effects from laparotomy with enterectomy. In the postsurgical period, the heart rate of horses in G 3 was higher (P ¼ .02) than the values obtained in G 1 and G 2. Upon the evaluation of degree of pain, statistically significant differences (P ¼.04) were identified between horses in G 1 versus G 3. G 3 animals presented a higher degree of pain. Regarding the erythrocytes (L/L), higher values were measured in G 3 (P ¼ .001) in comparison with G 1 and G 2. These results suggest that meticulous tissue handling is essential to minimize intestinal trauma and inflammation.
A rapid and strong laparoscopic-assisted gastropexy in dogs
American Journal of Veterinary Research, 2001
Objective—To develop a technique for laparoscopic gastropexy in dogs and evaluate effects on stomach position and strength of the adhesion between the stomach and abdominal wall. Animals—8 healthy dogs. Procedure—Dogs were anesthetized, and the abdomen was insufflated with carbon dioxide. A laparoscope was placed through a cannula inserted on the abdominal midline caudal to the umbilicus. Babcock forceps placed through a cannula inserted lateral to the right margin of the rectus abdominus muscle were used to exteriorize the pyloric antrum, a longitudinal incision was made through the serosa and muscular layer of the pyloric antrum, and the seromuscular layer of the pyloric antrum was sutured to the transversus abdominus muscle. After surgery, positive-contrast gastrography was used to evaluate stomach position and the onset of gastric emptying, and ultrasonography was used to assess stomach wall activity and mobility. Dogs were euthanatized 1 month after surgery, and tensile strengt...

To compare tissue specimens of canine abdominal organs collected by standard techniques (ST) and harmonic scalpel (HS) and to determine the effect of each technique on wound healing. Experimental. Twelve dogs. Paired biopsy samples (ST, HS) were collected from liver, spleen, adrenal gland, pancreas, stomach, jejunum, and bladder using laparoscopic or laparoscopic-assisted methods. Hemorrhage at biopsy sites was assessed (present or absent). Specimens were evaluated for diagnostic quality and histologic changes. Dogs were necropsied at 4 or 14 days postoperatively. HS incision caused less frequent hemorrhage of all organs except spleen. HS specimens had more coagulation necrosis than ST specimens, but both techniques yielded specimens that were sized similarly and were of diagnostic quality. At necropsy, HS biopsy sites of the stomach, jejunum, bladder, adrenal gland, and pancreas were more hyperemic than ST sites. There were more adhesions at jejunal and pancreatic ST biopsy sites. HS biopsy sites had more coagulation necrosis at days 4 and 14 postoperatively. Differences in fibrin deposition, inflammation, and fibrosis were present at biopsy sites of some organs at days 4 or 14 and in comparisons between days 4 and 14. Diagnostic quality biopsy specimens were obtained with HS and ST. Although HS-induced gross and histologic changes during the first 2 postoperative weeks, no clinical complications were observed. Both HS and ST can yield specimens with minimal hemorrhage and HS resulted in no apparent postoperative problems in normal dogs. Although HS caused more inflammation and adhesions at biopsy sites of the pancreas, adrenal gland, and jejunum, no clinical complications occurred.
Comparative Efficacy of Sutures and Suture less Techniques for Gastrotomy Incision closure in Dog
Advances in Animal and Veterinary Sciences, 2020
S tomach is the largest dilatation of gastrointestinal tract in canines which initiates digestion and also serves as reservoir of food. The empty organ adopts more J shapes, whereas the full is a more constant C shape (Slatter, 2003). Stomach inlet from esophagusis called cardia while outlet to duodenum is the pylorus, having cardiac and pyloric sphincters respectively. Stomach part closest to the cardia is fundus, which is bulging in shape while the restis smaller in size and named as body. Gastric folds on the interior surface help to grind and digest food while glands in the wall secrete gastric juices and hydrochloric acid which help to digest protein and fats (Coolman et al., 2000).Various surgical anomalies of the stomach include: gastric dilatation with volvolus, foreign bodies, gastric out flow obstruc-research Article Abstract | Gastrotomy is suggested in case of gastric dilatation with volvolus, gastric foreign bodies, gastric retention, out flow obstruction, hypertrophic gastropathy, gastric neoplasia, and gastro duodenal ulceration. Different techniques are considered to close gastric incisions like absorbable suturing material, stapler suture and use of adhesive glue. These techniques give different kind of effects on gastrotomy closure. The present study was carried out on 12 adult mongrel dogs with an average of 15 to 20 kg body weight. They were divided into three groups, each group having 4 animals and designated as group A, B and C. Standard Gastrotomy procedure was performed in group A (sutured as, first layer by simple continuous pattern followed by 2 nd layer of cushing sutures with Vicryl #1), B Linear Stapler , (Linear Gastric Stapler, Ethicon, Inc. Johnson and Johnson, USA) was used to close gastric incision while in group C gastrotomy site was closed by tissue adhesive glue Cyanoacrylate (Dermabond 0.5ml, Ethicon, Inc. Johnson and Johnson, USA). Comparison of all suturing and suture less techniques was carried out through Physical evaluation, food, water intake and defecation, Weight loss / gain, Complete Blood Count, Leakage evaluation by contrast radiography and postmortem findings. It was concluded that suturing technique (using absorbable suture material in two layers) considered much better than other two methods (adhesive glue and stapling) economically, due to use of ease and least post-operative complication. The results of this study will help veterinarian, field workers and pet practioners to use suturing technique as most effective and appropriate technique for gastrotomy closure in terms of better healing, less blood loss and least chances of post operation complications.
Result of Endoscopically Assisted Gastropexy in Dogs
Acta Veterinaria, 2014
The aim of this study was to investigate the use of endoscopy jointly with gastropexy in dogs as a potential mean to aid prevention and evaluation of the long-term efficiency of this procedure for gastric dilatation-volvulus. The study was performed on ten healthy adult medium- and large-breed dogs. The dogs had no abnormal finding upon physical examination and each underwent an endoscopically assisted gastropexy procedure. After surgery all dogs were in good condition. The surgical procedure was followed by x-ray and ultrasonographic examinations. The records included data for gastropexy anatomic location and length, duration of the surgical procedure and complications. The mean ± SD gastropexy length was 3.0 ± 0.25 cm, as determined by ultrasonography, and the mean duration of the surgical procedure was 20 ± 5 minutes. It appears that endoscopically assisted gastropexy is a simple, fast, safe, and reliable method of performing a prophylactic gastropexy in dogs. This procedure maxi...

Dogs are considered to be the best companions of human beings due to their loyalty, obedience and pleasant disposition. Jejunum is the largest part of small intestine mainly involved in absorption of nutrients. Jejunal resection up to 80% allows normal weight gain while resection up to 90% increased morbidity and mortality. In the present study, 20 dogs were divided into 4 groups based on the degree of jejunal resection i.e. A (70% resection), B (80% resection) and C (100% resection) while group D served as control. Dogs in the 70% and 80% jejunal resection group showed normal growth and function while 100% jejunal resection resulted in weight loss and alteration of hematological and biochemical parameters.
