Seven hundred and sixty-six (766) dogs met the criteria for inclusion. Sixty-seven different breeds were represented with Labrador Retriever (19.2%, n = 147), Golden Retriever (13.3%, n = 102), and German Shepherd Dog (6.6%, n = 51) being the most common. The sex distribution was 61% male (119 intact, 348 castrated) and 39% female (120 intact, 179 spayed). The median age was 4.9 years (range, 0.2–15.8), and the median weight was 33 kg (range, 6.4–120). Sixty-one dogs presented for elective prophylactic gastropexy at the time of castration or spay (ovariohysterectomy or ovariectomy based on clinician preference), of which there were 19 IG, 41 LAIG, and 1 TLIG. The remaining 705 dogs presented for emergency abdominal surgery where prophylactic IG was also performed. There were 165 unique combinations of abdominal procedures performed with IG (see Table 1).
Seven hundred and fifty dogs had notation of suture type used for the gastropexy. The suture types used for the gastropexy were polydioxanone (PDS, Ethicon) size 0 (n = 603), 2 − 0 (n = 19), and 3 − 0 (n = 2); poliglecaprone 25 (Monocryl, Ethicon) size 2 − 0 (n = 1); polypropylene (Prolene, Ethicon) size 0 (n = 20) and 2 − 0 (n = 1); barbed glycomer 631 (V-loc, Covidien) size 0 (n = 1) and 2 − 0 (n = 103); or not specified (n = 16). The gastropexy was secured in a continuous (n = 652) or interrupted (n = 8) pattern or not available in the records (n = 106). Orientation and length of gastropexy incisions were inconsistently noted.
All 766 dogs had short-term follow-up with a median of 13 days (range 7–55). Four hundred and forty-six dogs (58.2%) had additional follow-up with a median of 876 days (range 58-4450). Postoperative complications included 88 minor wound-related complications (11.5%, 95% CI = 8.44–12.52%) and 22 major complications (2.9%) requiring surgical intervention within the hospitalization or short-term follow-up period. Minor complications included superficial incision infection (84), incision abscess (3), and draining tract (1) that resolved with antibiotic therapy. Only 3 dogs had a direct (major) complication that could be associated with the gastropexy site including hemorrhage from the gastropexy site causing hemoabdomen (2) and infection with partial dehiscence (1). Table 2 lists the other major complications. The frequency of direct gastropexy complication was 0.4% (95% CI = 0.14–1.16%).
Of the 705 dogs that presented for abdominal emergency surgery and had IG performed, 466 dogs presented for a primary GI emergency and 239 dogs for a non-GI abdominal emergency. 145/466 dogs with a GI emergency had postoperative GI signs (144 presented for GIFB and 1 for intestinal mass resection), and 28/219 dogs with a non-GI abdominal emergency had postoperative GI signs. Table 3 lists the causes of postoperative GI signs identified in the 173 dogs. Of note, 11 dogs had transient postoperative GI signs that resolved with medical therapy and definitive diagnosis was not identified with an overall incidence of 1.4%, and 3 had persistent GI signs that did not respond to medical therapy and did not get additional diagnostic workup with an overall incidence of 0.4% (95% CI = 0.14–1.16%).
Of the 106 dogs with GIFB obstruction, 93 dogs had subsequent abdominal surgeries, and 80 of those were confirmed to have an intact gastropexy adhesion with proper positioning (range, 15-4450 days after the initial surgery with gastropexy). The remaining 13 dogs did not mention the gastropexy in the operative report. None of the 446 dogs with long-term follow-up in this study were diagnosed with GD (95% CI = 0.00-0.84%) or GDV (95% CI = 0.00-3.37%). Gastropexy malpositioning and bowel entrapment was not encountered in any dogs that had subsequent abdominal surgery.
