Summary of "Laparoscopic-Assisted Transanal Pull-Through in Hirschsprung Disease: Does Laparoscopic Dissection Minimize Anal Overstretching?"

Surgical treatment for Hirschsprung disease (HD) has evolved from a staged repair to a primary operation but is still associated with significant complications. Extensive transanal dissection may overstretch the sphincter and cause partial tear; however, laparoscopic dissection can decrease rectal overstretching. Thus, this study aimed to evaluate the outcome of surgical management of HD and the efficacy of laparoscopic-assisted transanal endorectal pull-through in infants and children in our center. We reviewed the medical records of 74 patients who underwent surgical repair of HD from 2006 to 2019. However, we excluded 42 patients with HD (patients with stoma [ = 33] and total colonic aganglionosis [ = 9]). The remaining 32 patients were divided into two groups. Group A included patients who had transanal pull-through with laparoscopic assistance only to visualize the transition zone, take a biopsy, and check for twisting or bleeding. Group B included patients who had laparoscopic-assisted transanal pull-through with dissection of the rectum. All patients had Soave repair with an approximate cuff length of 5 cm. Group A included 18 patients, whereas group B included 14 patients. Demographic data were comparable between the two groups with no significant difference in age or gender ( = .12 and .67, respectively). Patients in group A had longer operative time (210 ± 20.75 minutes versus 178 ± 18.92 minutes;  < .001) and hospital stay (6 ± 1.33 days versus 5 ± 1.24 days;  = .033). No significant difference was observed in postoperative complications between both groups (anastomotic site stricture,  = .295; persistent soiling,  = .238). Laparoscopic rectal dissection for managing HD is associated with less operative time and hospital stay. In addition, all procedures required for the repair can be safely performed using laparoscopy.

A specialized form of transanal endoscopic surgery for microscopically controlled operations in the RECTUM.

Surgical procedures conducted with the aid of computers. This is most frequently used in orthopedic and laparoscopic surgery for implant placement and instrument guidance. Image-guided surgery interactively combines prior CT scans or MRI images with real-time video.

The pull on a limb or a part thereof. Skin traction (indirect traction) is applied by using a bandage to pull on the skin and fascia where light traction is required. Skeletal traction (direct traction), however, uses pins or wires inserted through bone and is attached to weights, pulleys, and ropes.

A technique that came into use in the mid-1980's for assisted conception in infertile women with normal fallopian tubes. The protocol consists of hormonal stimulation of the ovaries, followed by laparoscopic follicular aspiration of oocytes, and then the transfer of sperm and oocytes by catheterization into the fallopian tubes.
