Abstract

RIBEIRO, MARIANA S. et al. New technique of intragastric sleeve: viability and survival in a pig model. An. Acad. Bras. Ciênc. [online]. 2018, vol.90, n.3, pp.3075-3080. ISSN 0001-3765.  https://doi.org/10.1590/0001-3765201820180199.

Developing a less invasive, practical and cost-effective operative technique for obesity treatment represents a pressing need for our society. In this way, intragastric single port sleeve by endoplication was tested in six pigs during 18 weeks. Celiotomy was performed with animal placed in dorsal decubitus position. Single port gastrostomy was performed and double tobacco pouch sutures were made in fundic region, making a gastric sleeve. At the end, stomach layers and skin were closed in a conventional manner. Means and the standard deviations of surgical time were calculated. The procedure was simple and all animals survived; there were no significant blood loss and no intra and postoperative complications. The procedure was fast (67.4 minutes). The technique has the advantage of not requiring the use of mechanical sutures, making it less costly. The innovation of this procedure was the use of a single port gastrostomy device to perform an intraluminal sleeve. What made this technique less invasive were the use of a single port, nonmanipulation of the stomach intra-abdominally, ease of execution and no need of pneumoperitoneum. The new technique is acceptable and has reproducible viability, had a short procedure time without intra and postoperative complications.
