A technique was developed for closure of gastrotomy and enterotomy incisions using disposable skin staples. The technique was used successfully in three dogs with gastrointestinal linear foreign bodies that required a gastrotomy and one or more enterotomies. The method allows for secure closure of gastrointestinal incisions and minimizes the surgical time in patients requiring multiple gastrointestinal incisions.
Seven different suture materials were implanted into the oral tissues of 12 cats. The sutures and surrounding tissues were retrieved en bloc from each of two cats on days one, three, seven, 14, 21, and 28 postimplantation. Tissue reaction and suture duration were evaluated by gross visual observation and histological examination. Chromic gut disappeared between days three and seven; polyglactin 910 disappeared between days 14 and 21; and polyglycolic acid disappeared as early as seven to 14 days. Polydioxanone still was intact at day 28 and is recommended as an absorbable material for procedures in which longer healing time is anticipated. All the nonabsorbable suture materials (i.e., polypropylene, stainless steel, and nylon) were intact at day 28 postimplantation. Visual inspection showed polypropylene to have the least tissue reaction.
A new method for attachment of a belt-loop gastropexy using disposable, stainless steel skin staples was compared with a traditional hand-sewn belt-loop gastropexy technique in 24 fresh dog cadavers. Mean gastropexy times were 212 seconds for the stapled technique and 435 seconds for the hand-sewn technique. The stapled belt-loop gastropexy was significantly faster than the hand-sewn technique (P less than 0.001). There was no statistically significant difference in the mean maximum tensile strength between the two attachment methods. This study provides a basis for clinical evaluation of the stapled belt-loop gastropexy technique in dogs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
