Insights
Surgical treatment for liver hydatid cysts varies in outcomes. Minimally invasive procedures offer shorter stays and fewer complications in selected patients, while open surgery has higher morbidity.
Area of Science:
- Hepatobiliary Surgery
- Parasitic Infections
- Surgical Outcomes Research
Background:
- Cystic echinococcosis is endemic, frequently affecting the liver.
- Hepatic hydatid cysts often necessitate surgical intervention due to size, symptoms, or complications.
Purpose of the Study:
- To evaluate surgical outcomes and complications of different hepatic hydatid cyst treatments.
- To compare various surgical approaches over a 19-year period.
Main Methods:
- Retrospective observational study of 146 patients (2004-2023).
- Classification into four surgical groups: open conservative, minimally invasive (PAIR/PAIR-D), radical/complex, and ultrasound-guided drainage.
- Analysis of demographic, operative, and postoperative data.
Main Results:
- Open conservative surgery (Mabit-Lagrot) was most common (45.9%).
- Overall complication rate was 25.3%, with recurrent abscessed cysts being most frequent.
- Minimally invasive procedures showed shorter hospital stays and lower complication rates in selected cases.
Conclusions:
- Surgical outcomes for hepatic hydatid cysts depend on invasiveness.
- Open surgery is effective but linked to higher morbidity; minimally invasive options are viable alternatives for select patients.
- Postoperative bilirubin and amylase levels indicate invasiveness, not necessarily complications.
Background:
Cystic echinococcosis remains endemic in many regions, with the liver representing the most affected organ. Surgical treatment is still required for large, symptomatic, or complicated hepatic hydatid cysts.
Objective:
To evaluate surgical outcomes and postoperative complications associated with different surgical approaches for hepatic hydatid cysts in a single-centre cohort over 19 years.
Methods:
This retrospective observational study included 146 patients who underwent surgical treatment for hepatic hydatid cysts at Mureș Clinical County Hospital between 2004 and 2023. Patients were classified into four groups according to the surgical technique: open conservative surgery (Mabit-Lagrot, with or without Kehr drainage), minimally invasive procedures (PAIR/PAIR-D), radical or complex surgery, and ultrasound-guided drainage. Demographic, operative, and postoperative outcomes were analysed.
Results:
The Mabit-Lagrot technique was the most frequently performed procedure (45.9%). Overall, postoperative complications occurred in 25.3% of patients, with recurrent abscessed hydatid cysts representing the most common event. Minimally invasive procedures were associated with shorter hospital stays and lower complication rates in selected cases. Postoperative total bilirubin and amylase levels differed significantly across surgical groups, with higher values observed after more invasive procedures.
Conclusion:
Postoperative outcomes following surgical treatment of hepatic hydatid cysts vary according to procedural invasiveness. While open surgery remains effective, it is associated with higher morbidity. Minimally invasive approaches represent valid alternatives in appropriately selected patients. Early postoperative bilirubin and amylase levels appear to reflect surgical invasiveness rather than predict complications.
