Insights
Single balloon-assisted colonoscopy successfully placed colonic manometry catheters in children with difficult constipation. This technique offers a safe and effective solution for challenging pediatric gastrointestinal procedures.
Area of Science:
- Pediatric Gastroenterology
- Gastrointestinal Endoscopy
Background:
- Colonic manometry is crucial for managing pediatric constipation but catheter placement is challenging due to colonic redundancy.
- Accurate catheter placement requires navigating tortuous colonic anatomy, often complicated by chronic constipation in children.
Purpose of the Study:
- To evaluate the efficacy and safety of single balloon-assisted colonoscopy for placing colonic manometry catheters in children.
- To introduce a novel technique for managing difficult colonoscopies in pediatric patients.
Main Methods:
- A retrospective chart review of 36 pediatric patients (ages 3-16) who underwent single balloon-assisted colonoscopy for colonic manometry catheter placement.
- Patients received nasogastric golytely for bowel preparation prior to the procedure.
Main Results:
- Successful colonic manometry catheter placement was achieved in all 36 patients.
- Procedure times ranged from 20 to 105 minutes, with no major complications reported.
Conclusions:
- Single balloon-assisted colonoscopy is a feasible and safe technique for performing difficult colonoscopies and placing colonic manometry catheters in children.
- This method may have broader therapeutic applications in pediatric endoscopy, including polyp removal.
Objectives:
Colonic manometry is used frequently in children with long standing and difficult to manage constipation to aid in management decisions. Accurate analysis requires placement of the colonic manometry catheter in the colon without looping. This is technically difficult due to the long-standing nature of the constipation in most patients leading to sigmoid and other colonic redundancy. Single balloon colonoscopy has been successfully used in adult in cases of difficult colonoscopy. We report the first series of single balloon-assisted colonoscopy for performing difficult colonoscopy in children and placing colonic manometry catheters.
Methods:
Retrospective chart review was performed to identify patients undergoing the procedure. All patients had prior preparation with nasogastric golytely.
Results:
Using the single balloon technique, 36 patients underwent placement of the colonic manometry catheter (ages ranging from 3 to 16 years, weights 12 to 95 kg). Catheter placement was successful in all cases with procedure times of 20 to 105 minutes. No major complications were noted.
Conclusions:
This is the first reported series of using single balloon-assisted colonoscopy to perform difficult colonoscopy in children and place colonic manometry catheters. It may have other therapeutic implications in children such as removal of polyps or placement of similar catheters.
