Doing everything extraperitoneally is a nice feature of the technique.
OpinionCathy
All of these techniques are good adjuncts to the armamentarium for Hirschsprung's disease, and knowing more techniques allows tailoring to appropriate patients.
OpinionCathy
One of the mistakes people make when doing a transanal pull-through is to stretch the sphincters and do the operation on the inside; it should be done by pulling everything out and doing it on the outside without stretching the sphincters.
Clinical
Aggressive sphincter stretching during the transanal approach may damage the sphincters.
Clinical
In early experience with laparoscopic Duhamel, the colon was brought outside to transect it and then put back, but with increased experience this is no longer done and a pretty short stump is left.
Clinical
Even if more stump is left, it can be trimmed later before closing the stump down.
Clinical
By doing all dissection from the inside, overstretching of the anus can be avoided.
Clinical
The end of a GIA stapler can be used for making the side-to-side anastomosis, allowing the procedure to be performed even in neonates at a very early age.
Clinical
A real pouch does not have to be left behind with this technique.
Clinical
The new Duhamel pull-through was designed to eliminate the septic intraabdominal step, avoid intraabdominal sutures, determine the length of the residual stump, and assure a more secure colorectal anastomosis.
Host summary
The first incision is made with electrocautery on the posterior wall of the rectum 1.5 centimeters from the dentate line.
Host summary
The retrorectal tissue is easily dissected digitally, allowing access to the retrorectal space to the sacral promontory.
Host summary
Dissection is performed along the lateral walls of the rectum approximately 50% of the circumference of the posterior rectal wall.
Host summary
The sigmoid colon is mobilized laparoscopically and pulled through the retrorectal space using a clamp placed transanally.
Host summary
The distal rectal segment is stapled transversely with a GIA stapler 75 millimeters, which can be reinforced with PDS or Vicryl invaginating sutures.
Host summary
The level at which to cut is defined by pathologic markers intraoperatively by frozen section or by mapping a transition zone with previous suction biopsies.
Host summary
The anastomosis is completed using the Martin technique and modification, leaving a very ample window with minimal chance of stenosis.
Host summary
At 6 months postoperatively, colonoscopy showed a residual pouch of approximately 3 centimeters in an asymptomatic patient.
Host summary
Problems that can occur include accumulation of feces, constipation, and fecal impaction when the stump is left too long.
Host summary
The residual stump can be divided if necessary using endoscopic techniques.
Host summary
The technique is recommended for all pediatric patients, including patients with very dilated colons, and is reproducible, easy, and fast with minimal incidence of constipation and stenosis.
