Summary
Laparoscopic pericystectomy offers a minimally invasive approach for hepatic hydatid cysts, reducing patient morbidity. This structured technique ensures complete cyst removal, minimizing recurrence risk and preserving liver function.
Area of Science:
- Hepatobiliary surgery
- Minimally invasive surgery
- Parasitic infections
Background:
- Laparoscopic pericystectomy is a minimally invasive alternative to open resection for hepatic hydatid cysts.
- Concerns exist regarding intraoperative cyst rupture due to reduced tactile feedback in laparoscopic procedures.
- Limited global experience with laparoscopic approaches for hydatid cysts necessitates structured techniques.
Observation:
- A 37-year-old male presented with symptoms of a large, complex hydatid cyst distorting hepatic anatomy.
- Preoperative imaging revealed a large cyst (8.8 x 8.2 x 11.3 cm) impacting hepatic veins and causing compensatory hypertrophy.
- Neoadjuvant albendazole treatment and 3D surgical planning were utilized.
Findings:
- A structured laparoscopic pericystectomy was performed, involving liver mobilization and parenchymal transection guided by major hepatic veins (RHV, AFV, IVC).
- Individual control of biliary radicals entering the cyst prevented postoperative biliary leakage.
- Complete cyst removal was achieved, preserving unaffected liver segments.
Implications:
- This multimodal approach, combining neoadjuvant albendazole and structured laparoscopic pericystectomy, offers a safe alternative to open surgery.
- Minimally invasive techniques can achieve complete cyst removal, reducing recurrence risk and associated morbidity.
- Preoperative 3D modeling and intraoperative guidance by major vessels are crucial for complex cases.
