Abstract OBJECTIVE: To determine the prevalence of Ureaplasma urealyticum and Mycoplasma hominis in couples with infertility that participated in a high complexity protocol for assisted reproductive techniques. MATERIALS AND METHODS: Observational longitudinal, retrospective and descriptive study in which pathogens from positive samples were collected from infertile couples during a high complexity protocol for assisted reproductive techniques in the Mexican Center for Fertility Dr. Alberto Kably Ambe (Hospital Ángeles Lomas) between 2016 and 2019. RESULTS: A total of 172 infertile couples participated in the study. As a protocol previous to the in vitro fertilization, culture was performed in women and men. Of the vaginal culture, 65.1% were reported positive and Ureaplasma urealyticum predominated on 52.9% of them. While 47.7% of the semen culture were positive, and Mycoplasma hominis was on 34.9% of them. CONCLUSIONS: In infertile women, we reported a prevalence of 52.9% of Ureaplasma urealyticum and 15.1% of Mycoplasma hominis. For men, the proportion of positive cultures of Mycoplasma hominis was higher with 34.9%, while Ureaplasma urealyticum had a prevalence of 15.2%. Both microorganisms were present in the cultures of 5.8% of women and 7.6% of men.

Resumen OBJETIVO: Determinar la prevalencia de Ureaplasma urealyticum y Mycoplasma hominis en parejas con infertilidad que ingresarán a un procedimiento de fertilización in vitro. MATERIALES Y MÉTODOS: Estudio observacional, longitudinal, retrospectivo y descriptivo, en el que se recabaron los patógenos de los cultivos positivos tomados de parejas con infertilidad que ingresaron a ciclo de fertilización in vitro en el Centro Mexicano de Fertilidad Dr. Alberto Kably Ambe (Hospital Angeles Lomas) entre los años 2016 a 2019. RESULTADOS: Se analizaron 172 parejas con infertilidad, a quienes se les realizó un cultivo como protocolo previo al procedimiento de fertilización in vitro. De los exudados vaginales se reportaron positivos el 65.1%, Ureaplasma urealyticum predominó en el 52.9% de ellos. Mientras que el 47.7% de los espermocultivos tuvieron algún patógeno, prevaleció Mycoplasma hominis en el 34% de los hombres. CONCLUSIONES: En las mujeres con infertilidad a quienes se realizó algún procedimiento de fertilización in vitro se reportó una prevalencia de 52.9% de Ureaplasma urealyticum y de 15.1% de Mycoplasma hominis. En los hombres, la proporción de cultivos positivos para Mycoplasma hominis fue de 34.9% y la de Ureaplasma urealyticum de 15.2%. Ambos microorganismos se encontraron en los cultivos de 5.8% de las mujeres y de 7.6% de los hombres.

RESUMO Introdução: O objetivo de nosso estudo foi descrever os resultados cirúrgicos do procedimento de Deloyer em nosso centro de referência e comparar os resultados de pacientes com e sem ileostomia de proteção. Métodos: Pacientes submetidos ao procedimento de Deloyer de 2013 a 2016 foram incluídos prospectivamente. Foram analisadas as características gerais, as variáveis intraoperatórias, o curso pós-operatório e os desfechos funcionais. Os pacientes foram comparados em dois grupos: Grupo 1) pacientes submetidos ao procedimento de Deloyer (PD) sem ileostomia, e grupo 2) procedimento de Deloyer com ileostomia de proteção (IP). Resultados: Foram incluídos 16 pacientes submetidos à transposição isoperistáltica da porção remanescente do cólon direito, dos quais 9 (63%) eram do sexo masculino com idade média de 47 anos (variação de 22-76) anos. A principal indicação cirúrgica foi a restauração do trânsito intestinal (62,5%). Houve maior morbidade maior no grupo IP, mas sem significância estatística (20% vs. 9%, p = 0,92). Nenhum vazamento ou óbito foi relatado. A duração da hospitalização foi de 7 dias. O número médio de evacuações por dia foi 4, aos 18 meses de seguimento. Apenas quatro (25%) pacientes utilizaram irregularmente a loperamida. Conclusões: O procedimento de Deloyer tem resultados satisfatórios e é reprodutível com baixa morbidade. As taxas de morbidades maiores e menores foram semelhantes entre os grupos, sugerindo que os custos e riscos de um segundo procedimento podem ser evitados proporcionando-se uma anastomose primária segura.

ABSTRACT Introduction: The objective of our study was to describe surgical outcomes of Deloyers procedure in our referral center, and to compare the results of patients with and without protective ileostomy. Methods: Patients undergoing a Deloyers procedure from 2013 to 2016 were prospectively included. General characteristics, intraoperative variables, postoperative course, and functional outcomes were analyzed. Patients were compared into two groups: group (1) patients undergoing Deloyers procedure without ileostomy, and group (2) Deloyers procedure with protective ileostomy. Results: Sixteen patients undergoing isoperistaltic transposition of the right colon remnant were included, of which 9 (63%) were males with a median age of 47 (range 22-76) years. The main surgical indication was the restoration of bowel transit (62.5%). There was higher major morbidity rate in the Deloyers procedure with protective ileostomy group, but without statistical significance (20% vs. 9%, p = 0.92). No leaks or deaths were reported. The length of hospital stay was 7 days. The mean number of bowel movements per day was 4 at 18 months of follow up. Only four (25%) patients used irregularly loperamide. Conclusions: The Deloyers procedure has satisfactory results and is reproducible with low morbidity. The major and minor morbidity rates were similar between groups, suggesting that the costs and risks of a second procedure can be avoided by providing a safe primary anastomosis.
