Insights
Postoperative liver function tests (LFTs) may not be reliable indicators after laparoscopic common bile duct exploration (LCBDE) for choledocholithiasis. This study suggests LFTs do not consistently downtrend following successful bile duct clearance in pediatric patients.
Area of Science:
- Hepatobiliary surgery
- Pediatric gastroenterology
- Minimally invasive surgical techniques
Background:
- Choledocholithiasis management often involves invasive procedures.
- Laparoscopic common bile duct exploration (LCBDE) offers potential benefits like reduced hospital stay and costs.
- Postoperative management strategies, particularly the utility of liver function tests (LFTs), require further investigation.
Purpose of the Study:
- To evaluate the trend of periprocedural liver function tests (LFTs) in pediatric patients.
- To compare LFT trends between endoscopic retrograde cholangiopancreatography (ERCP) and LCBDE.
- To determine if LFTs downtrend after successful ductal clearance in LCBDE.
Main Methods:
- Retrospective analysis of 99 pediatric patients (<18 years) undergoing ERCP or LCBDE.
- Inclusion criteria: at least one pre- and post-procedural LFT.
- Comparison of periprocedural LFTs (Tbili, AST, ALT, ALP) using Wilcoxon signed-rank tests.
Main Results:
- ERCP group (n=22) showed significant downtrends in Tbili, AST, ALT, and ALP (P < .001 to .002).
- LCBDE group (n=27) demonstrated a significant downtrend only in Tbili (P = .002).
- No significant downtrend in AST, ALT, or ALP was observed in the LCBDE group (P > .05).
Conclusions:
- The lack of consistent LFT downtrend in the LCBDE group challenges their utility for post-procedural management.
- Findings suggest LFTs may not be reliable indicators of successful ductal clearance after LCBDE.
- Further research is needed to establish optimal postoperative monitoring protocols following LCBDE.
Abstract:
Laparoscopic common bile duct exploration (LCBDE) utility in management of choledocholithiasis may decrease length of stay and patient cost, but postoperative management remains widely debated. We examined periprocedural LFTs for patients undergoing LCBDE and endoscopic retrograde cholangiopancreatography (ERCP) speculating for trend existence after successful LCBDE. We hypothesized that postoperative LCBDE LFTs would not downtrend even after successful ductal clearance. We identified 99 patients under 18 who underwent ERCP or LCBDE with at least one pre- and post-procedural LFT. Periprocedural LFTs between groups were compared using Wilcoxon signed-rank tests. The 22 ERCP patients demonstrated a significant downtrend across Tbili (P < .001), AST (P = .001), ALT (P = .002), and ALP (P < .001). The 27 LCBDE patients demonstrated a significant downtrend in Tbili (P = .002) only, while AST (P > .05), ALT (P > .05), and ALP (P > .05) were nonsignificant. Lack of consistent downtrend in the LCBDE group raises doubt regarding the utility of postoperative LFTs for post-procedural management.
