Individualized Drainage Strategy Based on Risk Stratification in Children Undergoing Surgery for Choledochal Cyst: A Prospective Randomized Controlled Trial
2026年9月12日 更新者:Xueqiang Yan
Application of Risk-Stratified Individualized Drainage Strategy in Children With Choledochal Cyst Undergoing Robot-Assisted Roux-en-Y Hepaticojejunostomy: A Prospective Randomized Controlled Trial
Choledochal cyst is a common congenital biliary malformation in children requiring cyst excision with Roux-en-Y hepaticojejunostomy.
Traditional practice routinely places abdominal drainage tubes postoperatively.
With the improved precision of robot-assisted surgery, the necessity of routine drainage has been questioned.
This prospective randomized controlled trial aims to evaluate whether a selective drainage strategy based on a preoperative predictive model (using cyst diameter, age, BMI, hemoglobin, and globulin) is safe and effective compared with conventional routine drainage in children undergoing robot-assisted Roux-en-Y hepaticojejunostomy.
The primary outcome is the incidence of Clavien-Dindo grade ≥III complications within 30 days postoperatively.

参与者组/臂 |
干预/治疗 |
|---|---|
|
实验性的:Selective Drainage Group
Patients with low-risk prediction (<85%) do not receive abdominal drainage; patients with high-risk prediction (≥85%) receive drainage tube placement.
|
All enrolled children undergo Da Vinci robot-assisted Roux-en-Y hepaticojejunostomy.
The intervention differentiates in postoperative drainage management: the Selective Drainage Group receives abdominal drainage only when preoperative risk probability is ≥85%, while the Conventional Drainage Group receives routine drainage for all patients.
|

有源比较器:Conventional Drainage Group
All patients receive routine abdominal drainage tube placement postoperatively.

All enrolled children undergo Da Vinci robot-assisted Roux-en-Y hepaticojejunostomy.
