[Transposition of gracilis muscle for treatment of recurrent anal and rectovaginal fistula].

BACKGROUND: Rectovaginal fistula is defined as a result of an abnormal connection between the rectum and vagina. It is often a result of inflammatory bowel disease, iatrogenic illness, malignancy or trauma. Rectovaginal fistula treatment is dependent on the classification of the fistula (simple or complex). There are few reports on transposition of gracilis muscle as a feasible option for treatment of rectal, vaginal and urethral fistula. CLINICAL CASES: We present the first three case experiences from the Instituto Nacional de Ciencias Medicas y Nutricion "Salvador Zubiran," a tertiary-care medical center in Mexico City. CONCLUSIONS: Gracilis muscle transposition is a feasible procedure in our population for treatment of recurrent rectovaginal and anorectal fistulas.

Interposición de músculo gracilis para reparar fístulas ano y rectovaginales recurrentes / Transposition of gracilis muscle for treatment of recurrent anal and rectovaginal fistula

Introducción: La fistula rectovaginal por definición es la que comunica la región anorrectal hacia la pared posterior de la vagina, como resultado de enfermedad inflamatoria intestinal, lesión iatrogénica, malignidad y trauma. El tratamiento depende de la clasificación de la fístula (simple o compleja). Existen a la fecha pocas publicaciones acerca del uso de la interposición del músculo gracilis como tratamiento factible y seguro para las fístulas rectales, vaginales y uretrales. Casos clínicos: En este artículo presentamos la experiencia inicial en tres pacientes a quienes se les realizó interposición del músculo gracilis, en el Instituto Nacional de Ciencias Médicas y Nutrición “Salvador Zubirán”, centro médico de tercer nivel en la ciudad de México. Conclusiones: El uso de músculo gracilis para reparar fístulas rectovaginales y anorrectales complejas es aplicable en nuestro medio si bien debe limitarse a fístulas recurrentes, después de haber fracasado con otros procedimientos.

Laparoscopic versus open total mesorectal excision: a nonrandomized comparative prospective trial in a tertiary center in Mexico City.

Because definitive long-term results are not yet available, the oncologic safety of laparoscopic surgery in rectal cancer remains controversial. Laparoscopic total mesorectal excision (LTME) for rectal cancer has been proposed to have several short-term advantages in comparison with open total mesorectal excision (OTME). However, few prospective randomized studies have been performed. The main purpose of our study was to evaluate whether relevant differences in safety and efficacy exist after elective LTME for the treatment of rectal cancer compared with OTME in a tertiary referral medical center. This comparative nonrandomized prospective study analyzes data in 56 patients with middle and lower rectal cancer treated with low anterior resection or abdominoperineal resection from November 2005 to November 2007. Follow-up was determined through office charts or direct patient contact. Statistical analysis was performed using chi2 test and Student's t test. Twenty-eight patients underwent LTME and 28 patients were in the OTME group. No conversion was required in the LTME group. Mean operating time was shorter in the laparoscopic group (LTME) (181.3 vs 206.1 min, P < 0.002). Less intraoperative blood loss and fewer postoperative complications were seen in the LTME group. Return of bowel motility was observed earlier after laparoscopic surgery. There was no 30-day mortality and the overall morbidity was 17 per cent in the LTME group versus 32 per cent in the OTME group. The mean number of harvested lymph nodes was greater in the laparoscopic group than in the OTME group (12.1 +/- 2 vs 9.3 +/- 3). Mean follow-up time was 12 months (range 9-24 months). No local recurrence was found. LTME is a feasible procedure with acceptable postoperative morbidity and low mortality, however it is technically demanding. This series confirms its safety, although oncologic results are at present comparable with the OTME published series with the limitation of a short followup period. Further randomized studies are necessary to evaluate long-term clinical outcome.

Factores asociados a mortalidad en cirugía mayor: análisis retrospectivo en un centro de referencia / Mortality associated factor in major surgery: retrospective analysis in a referral center

Background. There are very few studies that analyze surgical morbidity and mortality in the general population and the factors associated with those events. Objective. To determine factors associated to mortality in surgical procedures performed in a tertiary referral center in Mexico City. Methods. We retrospectively analyze surgical mortality in 4,157 consecutive surgical procedures performed in a one-year period from 1/1/2000 through 12/31/2000. Categorical variables were analyzed with the chi-square test and continuous variables with the t-Student test. Significance was defined as p < O.OB. Results. During the study period there were 76 postoperative deaths, representing a mortality rate of 1.82%. Mean patient's age in the entire cohort was 48.7 ± 17.6 years and for the patients who died in the postoperative period 57.8 ± 17.8 years (p < 0.05). Sixty-six percent of deaths were attributed to the primary or surgical disease. In 33.8% of postoperative deaths an adverse event was identified as responsible for the outcome. In 23% of cases there was a potentially preventable event, representing 0.3% of surgical procedures. Most patients (96.9%) had at least one co-morbid condition and 61.5% had two or more. Almost 80% of surgical deaths occurred in patients with ASA score III of TV and albumin levels below 3.5 g/dL. Most common cause of death was sepsis, reported in 35% of patients who died in the postoperative period. Conclusion. Surgical mortality in our series is low. In 0.3% of procedures it was detected a potentially preventable event. Postoperative deaths occurred in older patients with low albumin levels.

Introducción. Existen pocos estudios que analicen la mortalidad quirúrgica general y los factores asociados a la misma. Objetivo. Estudiar las causas y factores asociados a mortalidad quirúrgica en las intervenciones quirúrgicas realizadas en el INCMNSZ. Métodos. Se analizó en forma retrospectiva la mortalidad quirúrgica asociada a 4,157 procedimientos consecutivos realizados del 1/1/2000 al 31/12/2000. Los factores asociados a mortalidad fueron analizados mediante la prueba de chi-cuadrada para variables categóricas y t de Student para variables continuas. Se estableció como significativa a p < 0.05. Resultados. Durante ese periodo ocurrieron 76 muertes postoperatorias, lo que representa una mortalidad global de 1.82% para todos los procedimientos. El promedio de edad para los 4,157 procedimientos fue de 48.7 ± 17.6 años y para las muertes postoperatorias fue de 57.8 ± 17.8 años (p < 0.05). El 66.2% de las muertes se atribuyeron a la enfermedad de base o a la patología que motivó la cirugía. En 33.8% de las muertes se identificó algún evento diferente a la enfermedad primaria como responsable de la muerte. En 23% se identificó algún evento potencialmente prevenible, lo que representa 0.3% del total de eventos quirúrgicos. El 96.9% de los pacientes tenía al menos una comorbilidad y 61.5% cursaba con dos o más. El 78.5% de las muertes sucedió en pacientes ASA III-IV. El 80% de las muertes se asoció a niveles preoperatorios de albúmina por debajo de 3.5 g/dL. La causa de muerte más frecuentemente reportada fue sepsis en 35% de los eventos. Conclusión. La mortalidad postoperatoria en nuestra serie es baja. En 0.3% de los pacientes sometidos a cirugía se detectó algún evento potencialmente prevenible. Las muertes postoperatorias ocurrieron en pacientes más viejos y con niveles bajos de albúmina.
