Background:
It has been suggested that the outcome of transanal endorectal pull-through for classic Hirschprung's disease can be improved by laparoscopically mobilizing the colon before the pullthrough.
Methods:
Charts of 43 patients (2005-2009) with proven recto-sigmoid aganglionosis were retrospectively analyzed with respect to postoperative outcomes. Twenty-one had been treated with the transanal endorectal pull through (TERPT) and 22 with the laparoscopically assisted TERPT (LTERPT).
Results:
Gender ratio, congenital anomalies, preoperative enterostomy, and follow up did not differ between the groups. More colon was resected in the TERPT group: median 25 cm vs. 15 cm in the L-TERPT group (p<0.001). The TERPT-procedure took less time: median 153 min. vs. L-TERPT 263 min (p<0.001). Postoperatively, three patients showed colonic torsions after TERPT (p=0.07). The long-term clinical outcomes did not differ significantly between both groups. There was a significant association between length of resection and obstructive symptoms (OR=0.92, p=0.01).
Conclusion:
Postoperative and clinical outcomes are similar using the TERPT or L-TERPT to correct classic segment Hirschsprung's disease. Prevention of colonic torsion should be the prime concern during the TERPT procedure. L-TERPT requires laparoscopic equipment and takes more operation time, whereas TERPT leaves no visible scars. The positive relation between the larger length of resection and obstructive symptoms requires additional research.
