“…Since the population of dogs used in our study was composed of client-owned dogs of varying age, breed and size, it is difficult to compare these results with those obtained with purpose-bred research dogs. Indeed, our transit times more closely resemble those from a study investigating the effect of laparoscopic gastropexy on transit times in client-owned dogs (Balsa et al 2017). In that study, average capsule GET and TTT before surgery was in excess of 7 and 32 hours, respectively.…”

Objective To assess the effect of a high fat meal (fat loading) on gastrointestinal motility and the appearance of intestinal villi using video capsule endoscopy and ultrasound. Materials and Methods Four healthy staff‐owned dogs were included in a prospective blinded crossover study. Dogs had initial baseline video capsule endoscopy to measure gastrointestinal transit times and allow for visual assessment of intestinal mucosa. Abdominal ultrasound was also performed to obtain intestinal wall measurements and assess for the presence of mucosal hyperechoic speckling. All dogs had diagnostics repeated twice between one and two hours after ingestion of either corn oil or dairy cream for a total of four control and 16 fat loaded studies. Results Dogs in the corn oil group had greater mean gastric emptying times (740.3 ± 187.6 minutes vs. 237.9 ± 155 minutes) and total transit times (54.50 ± 22.2 hours vs. 23.25 ± 6.1 hours) than controls. Feeding of a fatty meal resulted in substantial retention of the capsules (10 of 16) within the stomach. While intestinal wall thickness of fat loaded dogs did not differ from control dogs, mucosal hyperechoic speckling scores of the duodenum of dairy cream dogs were greater when compared to control dogs (1.625 ± 0.518 vs. 0.500 ± 0.577). Clinical Significance Data from this pilot study provides further evidence that feeding of a small high fat meal results in ultrasonographic as well as visual changes to the intestinal mucosa of healthy dogs. This data suggests that previous recommendations to feed fatty meals to dogs with lymphangiectasia might not allow differentiation with healthy individuals. In addition, due to the marked effect on gastric emptying time, video capsule endoscopy should be avoided in dogs fed a high fat meal.

“…In the long‐term follow‐up, the two dogs did not show any clinical signs related to gastrointestinal disease. Although no coefficient of variability was measured in the similar study, Balsa et al also had a large, albeit not statistically significant, variation in the GET range of over 1000 min when comparing GET before and after their laparoscopic‐assisted gastropexy …”

“…Although no coefficient of variability was measured in the similar study, Balsa et al also had a large, albeit not statistically significant, variation in the GET range of over 1000 min when comparing GET before and after their laparoscopic-assisted gastropexy. 33 One explanation for both of our GET variations could be that the WMC is not the best method for measuring physiological activity in the stomachs of dogs in a minimally invasive manner. Although it is beneficial that patients do not have to be exposed to radiation for their gastrointestinal transit time measurements, Lidbury et al found that gastric retention, even in healthy dogs weighing > 30 kg, was a risk.…”

Evaluation of gastric motility in nine dogs before and after prophylactic laparoscopic gastropexy: a pilot study

Background The purpose of this study was to evaluate the effect of a prophylactic laparoscopic gastropexy on gastric motility in healthy large‐breed dogs. Methods This was a prospective pilot study with nine healthy client‐owned dogs. Each dog was its own control. Gastric motility was evaluated before and after laparoscopic gastropexy. Dogs were fed a standard diet three weeks before and after surgery. Gastric motility was measured before and 3 weeks after surgery. A wireless motility capsule (WMC) was used to measure gastric pH, intragastric pressure, temperature, frequency of contractions, motility index (MI) and transit time. Non‐parametric statistical analysis was used to compare the paired data. Clients were contacted for follow‐up information 2 years postoperatively. Results Median frequency of gastric contractions was 1.3 (range, 0.6–1.9 contractions/min) before gastropexy and 1.0 (range, 0.3–2.6 contractions/min) after gastropexy (P = 0.820). Median MI was 49.2 (range, 23.7–96.6) before gastropexy and 28.1 (range, 12.2–148.9) after gastropexy (P = 0.652). Median gastric emptying time was 1140 (range, 486–1230 min) before gastropexy and 1110 (range, 306–2610 min) after gastropexy (P = 0.570). During the hour before the WMC passed through the pylorus, median MI was 72.2 (range, 48.2–549.3) before gastropexy and 52.9 (range, 15.20–322.8) after gastropexy (P = 0.734), and frequency of contractions was 1.1 (range, 0.9–4.1 contractions/min) before gastropexy and 1.2 (range, 0.5–3.0 contractions/min) after gastropexy (P = 0.652). Conclusion Motility in the stomach did not change in healthy dogs after prophylactic laparoscopic gastropexy. We conclude that preventive laparoscopic gastropexy does not induce gastroparesis.

“…Various methods such as conventional and contrast radiography, ultrasonography, nuclear markers, electromyography, radioactive tracers and motility capsules have been used to evaluate small intestinal motility (Caride et al 1984, Dromehl et al 1985, De Ridder et al 1989, Penninck et al 1989, Wiederkehr et al 1992, Choi et al 2001, Balsa et al 2017, in addition to radiopaque markers (Chandler et al 1990, Allan et al 1996, Chandler et al 1997, Sparkes et al 1997, Robertson & Burbidge 2000, Nelson et al 2001, Boscan et al 2006, Johnson et al 2017. Optimal dosing techniques of radiopaque markers in dogs include the use of 1.5-mm spheres fed in canned dog food, baby food or fed in a kibble ration.…”

Objectives To quantify changes in gastric and intestinal emptying times in the conscious dog following gastrointestinal acupoint stimulation. Materials and Methods In a randomised, blinded crossover study, six dogs were fed 30×1.5 mm barium‐impregnated polyethylene spheres and underwent: (1) no acupuncture (Control); (2) stimulation of target points PC6 and ST36 (Target) and (3) stimulation of non‐target points LU7 and BL55 (Sham). Abdominal radiographs were assessed immediately after feeding the spheres and every hour for 12 hours and their number in the stomach and large intestines was counted. Results The number of barium‐impregnated polyethylene spheres found distal to the stomach was less in the Target group compared to the Control and Sham groups between hours 2 and 4, but no differences between groups were seen for the remainder of the treatment period. The number of spheres found within the colon/rectum was less in the Target group compared to the Control and Sham groups between hours 4 and 6, and compared to the Sham group only at hour 7 but no differences between groups were seen after hour 8. Clinical Significance Acupuncture targeted at the gastrointestinal tract of dogs was associated briefly with slowed gastric emptying and gastrointestinal transit time. This foundational study lays the groundwork for additional studies of acupuncture effects associated with altered physiologic states.
