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).

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.

[Mortality-associated factors 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.
