Purpose: Our technique of fistula ligation and centering of bowel during the laparoscopically-assisted anorectal pull-through (LAARP) for the high-imperforate anus is described.
Methods: The distal rectum is dissected laparoscopically. About 1 in proximal to the termination of the rectum, we commence a subseromuscular dissection to create a mucosal tube of the distal rectum up to the urethra. This mucosal tube is then ligated and sharply divided. Under laparoscopic guidance, the needle is inserted between the two bellies of Levator Ani muscle, just posterior to the urethra. Simultaneous external stimulation confirms the optimal position. A guide wire is then passed through the needle. The tract is serially dilated and the anoplasty completed.
Results: This technique has overcome the problem of residual urethral diverticulum in our cases.

Department of Pediatric Surgery, Hokkaido Medical Center for Child Health and Rehabilitation, 1-1-240-6, Kanayama, Teine-ku, Sapporo, Hokkaido, 006-0041, Japan.
Purpose: This study aimed to identify surgical site infection (SSI) risk factors after anal reconstruction surgery in patients with anorectal malformations (ARMs).
Methods: This retrospective analysis from January 2013 to December 2022, including all pediatric surgical facilities in Hokkaido, Japan, examined consecutive patients with ARMs, excluding cloacal cases, regarding perioperative and SSI factors during their initial anal reconstruction surgeries.
Results: This study involved 157 cases of major clinical groups and 7 cases of rare/regional variants, among whom 4% developed SSIs.
Comparative analysis of hybrid transumbilical and anal laparoscopic pull-through versus totally transanal laparoscopic assisted pull-through for common type Hirschsprung's disease.

Department of Pediatric Surgery, The Second Hospital of Hebei Medical University, Shijiazhuang, 050000, Hebei, People's Republic of China.
Objective: To compare the efficacy of hybrid transumbilical and anal laparoscopic pull-through (HTALP) and totally transanal laparoscopic assisted pull-through (TTLAP) for the treatment of common type Hirschsprung's Disease (HD).
Methods: A retrospective investigation was performed on the clinical data of children with common type Hirschsprung's disease who underwent either HTALP or TTLAP between 2010 and 2020. A comparative analysis was conducted between the two groups in terms of general patient information, operative time, postoperative defecation recovery interval, bowel control, and postoperative anorectal manometry.
Impact of Epithelial Claudin-4 and Leukotriene B4 Receptor 2 in Normoganglionic Hirschsprung Disease Colon on Post Pull-through Enterocolitis.

Purpose: To investigate whether Leukotriene B4 receptor 2 (BLT-2), an upstream regulator of tight junction protein (TJP) Claudin-4, and TJPs could be etiologic factors in Hirschsprung-associated enterocolitis (HAEC) after pull-through (PT) for Hirschsprung disease (HD).
Methods: Normoganglionic colon (HD-N) and aganglionic rectum (HD-A) specimens from rectal/rectosigmoid (R/RS) or descending/transverse (D/T) HD were assessed using quantitative polymerase chain reaction (qPCR) for Occludin, TJP-1, TJP-2, Junctional adhesion molecule (JAM)-1, JAM-2, Claudin-1, Claudin-3, Claudin-4, and BLT-2 and immunoblotting for Claudin-4 using fresh specimens obtained intraoperatively (2021-2024; n = 17; R/RS = 15 and D/T = 2). Claudin-4 immunohistochemistry was also evaluated quantitatively using preserved (n = 29; R/RS = 20 and D/T = 9; 2009-2021) and fresh HD specimens for comparison with anorectal malformation patients having colostomy closure as controls (n = 42) and between HD-A versus HD-N, R/RS versus D/T, and HAEC (+) versus HAEC (-).
The long-term post-surgical outcome of intermediate anorectal malformation in our department.

Background: Posterior sagittal anorectoplasty and laparoscopic-assisted anorectal pull-through are preferred for anorectal malformation (ARM) today, while careful pull-through procedures with sacroperineal approach yield excellent outcomes. This study focuses on a pull-through procedure emphasizing continence mechanism preservation and compares outcomes with historical studies with various procedures.
Methods: Bowel function of patients with intermediate ARM followed up for over 10 years post-surgically was assessed.

Rectovaginal fistulas (RVF) represent less than 5% of anorectal fistulas. The classification of RVF is based on the localization (low vs. high) and the etiology.
