About this study
Official title: Comparison of Robot-assisted With Laparoscopic-assisted Modified Soave With Short Muscular Cuff Anastomosis for Classical Hirschsprung Disease
Hirschsprung disease (HSCR) is a rare congenital intestinal disease characterized by the absence of ganglion cells in the distal rectum, extending for variable distances into the proximal intestine.The \"pull-through\" reconstruction procedure described in 1949 by Orvar Swenson involving the removal of the aganglionic bowel and creating an anastomosis between the normally innervated bowel and the anal canal, remains the standard surgical approach for HSCR today. However, as rectal dissection by laparotomy in infants is technically difficult and can result in high rates of complications, other pull-through techniques were developed and several techniques are still widely used today.
In our institute, we developed the laparoscopic-assisted modified Soave with short muscular cuff anastomosis in July 2017, and achieved good therapeutic effects. However, there have some patients suffered soiling incidents in the short period post-surgery.

Therefore, we developed the robot-assisted modified Soave with short muscular cuff anastomosis procedures to protect the vital nerve and blood vessels of the pelvis from injury, decrease the injury of the sphincter.
this clinical trials was to compare the efficacy of robot-assisted and laparoscopic-assisted modified Soave with short muscular cuff anastomosis procedures for classical Hirschsprung disease (HSCR).
Read the detailed description
Soave's first report on the endorectal pull-through without anastomosis approach to the treatment of Hirschsprung disease (HSCR) dates back to 1963. With the rapid development of laparoscopic operations in the early 1990s, Georgeson et al reported a technique utilizing laparoscopic dissection of the rectum combined with anal mucosal dissection in 1995. Subsequently, many laparoscopic approaches to modified Soave-Georgeson procedures were described, including short muscular cuff anastomosis, long cuff dissection, and short V-shaped partially resected cuff anastomosis.The purpose of these modifications is to decrease postoperative complications due to internal anal sphincter achalasia and rectal cuff.
Wester et al used a short cuff operation that retained a muscular cuff of 1-2 cm and achieved excellent outcomes. Due to our increased experience to Soave-Georgeson operation, we have modified the Soave-Georgeson procedure that developed laparoscopic stepwise gradient cutting muscular cuff procedure and shortened the muscular cuff to approximately 1-2 cm in neonates and infants, or 3-4 cm in children. Good results using the laparoscopic stepwise gradient cutting muscular cuff (LSGC) procedure have been reported by Zheng et al.
Although a few patients suffered enterocolitis of the LSGC procedure, we found that the incidence of enterocolitis in patients with a 1-2cm muscular cuff was lower than that in patients with a 3-4 cm muscular cuff. According to the above finding, we developed the laparoscopic-assisted modified Soave with short muscular cuff anastomosis in July 2017, and achieved good therapeutic effects. However, there have some patients suffered soiling incidents in the short period post-surgery.
Therefore, we developed the robot-assisted modified Soave with short muscular cuff anastomosis procedures to protect the vital nerve and blood vessels of the pelvis from injury, decrease the injury of the sphincter.
this clinical trials was to compare the efficacy of robot-assisted and laparoscopic-assisted modified Soave with short muscular cuff anastomosis procedures for classical Hirschsprung disease (HSCR).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
RAMSProcedure or surgery
The robotic arms were oriented from the caudal direction. Dissection was begun circumferentially at 1.0 cm above the peritoneal reflection. The rectum was mobilized outside the longitudinal muscle layer, with the anatomical plane farther away from Denonvillier's fascia and the nerve plexus anterior or lateral to the rectum. The mobilization of the rectum reached 4-7 cm into the pelvis. After the robot was unlocked, a circular incision was made 0.5-1 cm from the dentate line, dividing the mucosa upward by 0.5-1.0 cm, breaking through the muscular cuff, and exposing the robotic dissection plane in the pelvis. The diseased colon was then gently pulled out through the anus. The posterior wall of the muscular cuff was completely removed along the left and right sides, accounting for two-thirds of the whole circular muscular cuff to 0.5 cm of the dentate line edge. One third of the anterior wall of the muscular cuff was retained,we then performed Soave's anastomosis.
LAMSProcedure or surgery
The mesentery of the colon was separated by laparoscopy with the vessel of the pull-through bowel preserved. Under the rectal peritoneal reflex, close to the rectal wall separate with the electric hook, the anterior wall of the rectum was separated to the bladder neck or the posterior wall of the vagina. The posterior wall of the rectum can be separated down to 1cm above the dentate line. After the laparoscopy was unlocked, a circular incision was made 0.5-1 cm from the dentate line, dividing the mucosa upward by 0.5-1.0 cm, breaking through the muscular cuff, and exposing the laparoscopic dissection plane in the pelvis. The diseased colon was then gently pulled out through the anus. The posterior wall of the muscular cuff was completely removed along the left and right sides, accounting for two-thirds of the whole circular muscular cuff to 0.5 cm of the dentate line edge. One third of the anterior wall of the muscular cuff was retained,we then performed Soave's anastomosis.

Questions about this trial
What is this clinical trial studying?
A study testing RAMS and LAMS in people with Hirschsprung Disease, run by Zunyi Medical College at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 9 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Ze bing prof. Zheng, M D (18285269257, zebing1988@sina.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
