“…The smallest dog in this study weighed approximately 21 kg; the use of wireless motility capsules in small dogs was not assessed in this study. The minimum weights of dogs in other studies receiving the same wireless motility capsule used in this study were similar (19–23 kg) . Investigation of the use of the capsule in smaller dogs would be useful, although not likely pertinent when referring to prophylactic gastropexy procedures, as GDV is uncommon in this cohort of dogs.…”

BackgroundProphylactic gastropexy has been promoted as a means of preventing gastric volvulus during gastric dilatation and volvulus (GDV) syndrome. Little is known about the impact of gastropexy on gastrointestinal transit time.HypothesisLaparoscopic‐assisted gastropexy (LAG) will not alter gastrointestinal transit times when comparing gastric (GET), small and large bowel (SLBTT), and whole gut transit times (TTT) before and after surgery.Animals10 healthy client‐owned large‐breed dogs.MethodsProspective clinical trial. Before surgery, all dogs underwent physical examination and diagnostic evaluation to ensure normal health status. Dogs were fed a prescription diet for 6 weeks before determination of gastrointestinal transit with a wireless motility capsule. LAG was then performed, and dogs were fed the diet for 6 additional weeks. Measurement of transit times was repeated 6 weeks after surgery.ResultsTen dogs of various breeds at‐risk for GDV were enrolled. No complications were encountered associated with surgery or capsule administration. There were no significant differences in GET 429 [306–1,370] versus 541 [326–1,298] (P = 0.80), SLBTT 1,243 [841–3,070] versus 1,540 [756–2,623] (P = 0.72), or TTT 1,971 [1,205–3,469] versus 1,792 [1,234–3,343] minutes (median, range) (P = 0.65) before and after LAG.Conclusions and Clinical ImportanceAn effect of LAG on gastrointestinal transit time was not identified, and wireless motility capsule can be safely administered in dogs after LAG.

“…The peak value of contraction pressure was 0.24 ± 0.05 kPa, which is relatively small [14], [15]. This could be because the animal was under anesthesia, which decreases the small intestine's motility [27].…”

“…The capsule must distinguish between contact pressure caused by contraction of the GI tract and ambient pressure. The resolution of the measuring unit should be sufficiently high to measure a weak peristaltic or segmentation contraction as low as 0.1 kPa [27]. The capsule should transmit measuring data via wireless communication to an in vitro receiver.…”

A tethered pressure measurement capsule was developed for measuring the small intestine contraction pressure to assist in locating capsules within the gastrointestinal (GI) tract and quantifying the contact force between the capsule and the small intestine lumen. The capsule was calibrated statically and dynamically in depth-controlled water at body temperature (37-38 °C). In vitro tests were performed on an intestinal simulator to verify the measurement function of the capsule. To perform a preliminary evaluation of its pressure measuring capabilities, the capsule was tested at a single location in a live pig model. The pressure signal from the live animal test was analyzed in the time domain, and then, the empirical mode decomposition and fast Fourier transformation were applied to analyze the contraction pressure and ambient pressure in the frequency domain. The contraction rate was 9.4 to 11.0 times per minute. The peak value of the contraction pressure was 0.24 ± 0.05 kPa. The successful test of this prototype lays the groundwork for a future untethered, swallowable version of the capsule, which will be capable of measuring dynamic pressures while in transit.
