RESUMO
OBJECTIVE: To assess the effectiveness of various sealing techniques in cholecystotomies under maximum intraluminal pressure stress using an ex vivo swine model. SAMPLE: 30 gallbladders from different animals were used. METHODS: The experiment was conducted ex vivo, with the formation of 3 groups, each comprising 10 samples. Group 1 utilized a traditional single-layer Cushing suture made from polydioxanone material. Group 2 employed a single layer of Cushing suture, also made from polydioxanone material, but in conjunction with surgical glue (n-butyl cyanoacrylate). Group 3 relied solely on the use of surgical glue (n-butyl cyanoacrylate) for sealing the edges of the surgical wound. The intraluminal pressure was gauged with a pressure transducer. RESULTS: The maximum intraluminal pressures (mean ± SD) sustained in G1, G2, and G3 were, respectively, 48.70 ± 21.32 mm Hg, 110.90 ± 37.52 mm Hg, and 10.9 ± 4.07 mm Hg. Comparisons between groups showed that G2 supported significantly higher pressures (56.1% higher) than G1 (P < .001) and G3 (90.2% higher; P < .001). When G1 was compared with G3, a significantly higher pressure (77.6%) was also observed (P < .01). CLINICAL RELEVANCE: The study's conclusions demonstrated the safest suture techniques for the gallbladder and provided advice regarding the use of surgical glue.
