Use of a duodenal serosal patch in the repair of a colon rupture in a female Solomon Island eclectus parrot

Abstract

Case Description-A 444-g (0.98-lb) 4-year-old sexually intact female Solomon Island eclectus parrot (Eclectus roratus solomonensis) was referred and evaluated for a suspected colonic obstruction. Clinical Findings-The parrot had a 3-day history of not passing feces and lack of appetite following treatment of dystocia that included percutaneous collapse of the egg and manual removal of egg fragments via the cloaca. During this procedure, a tear in the cloacal mucosa developed. The tear was repaired via a midline cloacotomy. Although clinically stable at the time of referral, the parrot became lethargic and bradycardic and had delayed crop emptying. Treatment and Outcome-A midline celiotomy and cloacotomy were performed to relieve the colonic obstruction, during which the severely distended colon ruptured. The colonic defects were closed in a simple interrupted pattern, and a serosal patch was applied by use of the adjacent duodenum. The bird recovered uneventfully from anesthesia and was passing voluminous feces with mildly increased effort within 1 hour after surgery. At 3 weeks after surgery, the parrot was passing feces with no increase in effort and had a normal appetite. Clinical Relevance-Application of a duodenal serosal patch for repair of a colon rupture was successful in this parrot. Gastrointestinal obstruction is rare in birds, but should be considered in birds that have regurgitation, decreased fecal production, and gastrointestinal dilation. Because birds lack an omentum, serosal patching with adjacent duodenum should be considered as a viable option in avian surgery.

Efficacy of Serosal Patching in Dogs with Septic Peritonitis

“…Birds do not have an omentum; thus, use of a serosal patch can be a viable alternative in birds. 21 The serosal patch has been described for cases in which a duodenal defect could not be closed primarily due to risk of luminal compromise. 9,11,22 Its use has been expanded for reinforcement of intestinal closures where either the suture line is of questionable viability or the abdominal environment is nonconducive to healing.…”

Evaluation of intraluminal pressure in cystorrhaphies with and without intestinal serosal patch supplementation from canine cadavers

“…. Serosal patching has being described as a well succeeded supplemental technique when employed to different organs and species 1,5,8,[10][11][12][13][14][15][16][18][19][20] . However, one study showed that the use of a serosal patch over intestinal anastomosis did not increase the survival of dogs with peritonitis, when compared to individuals that did not receive such supplementation 15 .…”
