Combined Radial Incision and Steroid Injection for Refractory Colorectal Stenosis After Pull-Through Surgery in Hirschsprung Disease: An Innovative Conservative Treatment.

BACKGROUND: Anastomotic stenosis after pull-through surgery remains a challenge in the management of Hirschsprung disease. Based on the management of esophageal stenosis, we evaluated the efficacy of combined radial incision and steroid injection for the treatment of refractory colorectal anastomotic stenosis after pull-through. IMPACT OF INNOVATION: Combined radial incision and steroid injection is an alternative conservative treatment of refractory anastomotic stenosis after pull-though for Hirschsprung disease, avoiding a potential complicated redo pull-though surgery. TECHNOLOGY MATERIALS AND METHODS: We included patients with recto-sigmoid Hirschsprung disease that developed a refractory anastomotic stenosis after a laparoscopic-assisted Swenson pull-through at Robert-Debré Children University Hospital, Paris, France. Refractory stenosis was defined as obstructive symptoms associated with an anastomotic stenosis upon rectal exam without improvement after serial anal dilatations. Under general anesthesia, an injection of 10mg delayed-action steroid per quadrant was combined with a radial incision of the stenosis using monopolar cautery. PRELIMINARY RESULTS: Combined radial incision and steroid injection was performed in 4 children, for either early or late refractory stenosis. This resulted in improvement of refractory anastomotic stenosis, avoiding a redo pull-through in 75% of patients. One child presented with transient improvement after combined radial incision and steroid injection but developed recurrent stenosis despite additional combined radial incision and steroid injection and redo pull-through. The median follow-up was 29 months. CONCLUSION AND FUTURE DIRECTIONS: We observed a clinical improvement in all the patients after combined radial incision and steroid injection. Steroids injection should be considered as a potential alternative therapy for anastomotic stenosis.

Efficacy of an expandable prosthesis placement after left pneumonectomy for soft tissue Ewing sarcoma in a 5-year-old child: 10 years follow-up.

We report the case of a 5-year-old girl who underwent left pneumonectomy for Ewing sarcoma of the lung. Two expandable prostheses were placed in the left hemi-thorax to prevent post-pneumonectomy syndrome and to protect the heart from radiotherapy. With a follow-up of 10 years, the procedure proved to be effective both on post-pneumonectomy syndrome and on cardiac protection.

Scarless laparoscopic incisions in Pfannenstiel (slip): the first 50 cases using an innovative approach in pediatric robotic surgery.

Incisions in the supra-pubic region have been described robotic-assisted surgery to improve cosmetic results in adults, but seldom in children. We aimed to present an innovative trocar placement in the Pfannenstiel line, named Scarless Laparoscopic Incisions in Pfannenstiel (SLIP), and evaluate its feasibility for various intra-abdominal procedures and its cosmetic results in pediatric robotic surgery. We performed a monocentric prospective study, including children undergoing robotic-assisted surgeries using a SLIP approach (July 2019-September 2021). Data regarding demographics, surgery, and outcome were collected and reported as median (range), or number (percentage). Cosmetic results were evaluated with a questionnaire. A SLIP approach was performed in 50 children (24 cholecystectomies, 12 splenectomies, 2 cholecystectomies and splenectomies, 9 colonic resections, 2 choledochal cyst resections, and 1 pancreatic pseudocyst resection). Median age was 11 years (2-18) and median weight 35 kg (10.5-80). Conversion to laparoscopy occurred in two cases. Post-operative complications occurred in 5 patients (10%), after colectomies [intrabdominal abscess (n = 3), stoma dysfunction (n = 1), parietal abscess (n = 1)], of which 3 (6%) required reintervention (intrabdominal abscess n = 2, stoma dysfunction n = 1). Regarding scars, 68% (n = 28) of parents and patients reported the maximal score of 5/5 for global satisfaction and 63% (n = 26) had all scars hidden by underwear. SLIP approach is versatile and can be used in supra- and infra-mesocolic robotic-assisted procedures. The low complication rate shows its safety in both young children and teenagers and does not increase operative difficulties. It results in high patient satisfaction regarding scars, and a scarless abdomen.
