El uso del separador/protector circunferencial mostró una diferencia estadísticamente significativa para la prevención de ISQ con una p = 0.031 (OR de 8.5). Seis afectados pertenecían al Grupo A y sólo 1 al Grupo B.

La aleatorización se realizó 1:1 de manera consecutiva y el análisis estadístico se hizo mediante prueba exacta de Fisher y chi cuadrada, con el software IBM Statistical Package for the Social Sciences, versión 16.0 para Mac (IBM SPSS Inc., Chicago, IL, USA). Los pacientes fueron atendidos con cirugía de urgencia y fueron divididos aleatoriamente en dos grupos: 20 casos sin utilizar el separador (grupo A) y 21 casos utilizándolo (grupo B).
Se incluyó a cuarenta y un pacientes atendidos en un hospital de tercer nivel. Nuestro objetivo fue demostrar la utilidad de un separador/protector circunferencial para evitar las infecciones de sitio quirúrgico (ISQ) en pacientes sometidos a cirugía colorrectal de urgencia. El empleo de separadores de herida está enfocado en evitar la contaminación y el trauma mecánico. Más del 20% de las infecciones asociadas al cuidado de la salud aparecen en sitios quirúrgicos y la prevalencia es mayor en los procedimientos colorrectales debido a la carga bacteriana asociada. In the present prospective randomized pilot study, the use of the circumferential wound retractor/protector significantly decreased the likelihood of surgical wound infection in emergency colorectal surgery. In addition, preoperative blood glucose levels below 200 mg/dl provided a 3.2-times higher protective effect, compared with glucose levels above 200 mg/dl. The use of a circumferential wound retractor/protector was statistically significant for the prevention of surgical wound infections, with a p = 0.031 and an OR of 8.5. Six group A patients developed SSI versus one group B patient. The chi-square and Fisher's exact tests were employed for the quantitative variables, and the statistical analysis was performed using the IBM Statistical Package for the Social Sciences software for Mac, version 16.0 (IBM SPSS Inc., Chicago, IL, USA). Subjects were assigned to a group in a 1:1 randomization allocation ratio. Methodsįorty-one patients that underwent emergency open surgery at a tertiary care hospital were randomized into 2 groups: 20 cases without the retractor (group A) and 21 cases with the retractor (group B). Our aim was to demonstrate the usefulness of a circumferential wound retractor/protector for the prevention of surgical site infections (SSIs) in emergency colorectal surgery. Surgical wound protectors are designed to prevent contamination and mechanical trauma. More than 20% of healthcare-associated infections correspond to those at surgical sites, and there is a higher incidence of infections in colorectal surgery due to the associated bacterial load. The journal accepts original articles, scientific letters, review articles, clinical guidelines, consensuses, editorials, letters to the Editors, brief communications, and clinical images in Gastroenterology in Spanish and English for their publication. The scientific works include the areas of Clinical, Endoscopic, Surgical, and Pediatric Gastroenterology, along with related disciplines. The principal aim of the journal is to publish original work in the broad field of Gastroenterology, as well as to provide information on the specialty and related areas that is up-to-date and relevant. Its pages are open to the members of the Association, as well as to all members of the medical community interested in using this forum to publish their articles in accordance with the journal editorial policies. The Revista de Gastroenterología de México (Mexican Journal of Gastroenterology) is the official publication of the Asociación Mexicana de Gastroenterología (Mexican Association of Gastroenterology).
