Patients aged <18 y who underwent a pull-through procedure between 2011 and 2017 were retrospectively identified. Patient data included diagnosis, procedure, administration of mechanical bowel preparation, and duration of perioperative intravenous (IV) antibiotics. Outcomes of interest included surgical site infections and anastomotic complications.
A total of 180 patients met inclusion criteria, of which 47.2% received mechanical bowel preparation. The combined rate of infectious and anastomotic complications was 12.2%. There was no significant difference in combined complication rate among those receiving bowel preparation compared with those who did not (14.1% versus 10.5%, P = 0.46). Administration of bowel preparation in the perineal anoplasty subgroup was associated with higher rates of wound infection (33.3% versus 3.3%, P = 0.05). One hundred five patients (58.3%) received perioperative IV antibiotics for ≤24 h. This group had similar rates of complications (13.3%) compared with those receiving IV antibiotics for longer than 24 h (11.6%, P = 0.74).
Although mechanical bowel preparation did not affect the overall complication rate for pull-through procedures, it was associated with more wound infections in those undergoing perineal anoplasty. Duration of postoperative IV antibiotics was not significantly associated with the rate of wound and anastomotic complications.
