An interventional study of omentoplasty and External Tube Drainage in Hepatic Cystic Echinococcosis, sponsored by Ataturk University. Completed at 1 site in Turkey (Türkiye). Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2026-08-28.

This prospective comparative study evaluated two surgical techniques for residual cavity management following conservative surgery for complicated hepatic cystic echinococcosis. Patients undergoing surgery were managed with either omentoplasty or tube drainage. The study aimed to compare postoperative outcomes between the two techniques, with particular emphasis on postoperative complications and residual cavity-related complications. Long-term follow-up was also performed to assess recurrence and other clinical outcomes.
Cystic echinococcosis of the liver may be associated with complications such as biliary communication, infection, rupture, cholangitis, and involvement of adjacent structures. Following conservative surgical treatment, appropriate management of the residual hepatic cavity remains an important component of surgical care.
This prospective, single-center comparative study was conducted at Atatürk University Faculty of Medicine and included adult patients undergoing conservative surgery for complicated hepatic cystic echinococcosis. Eligible patients were allocated to residual cavity management with either omentoplasty or tube drainage according to a predetermined alternating allocation strategy.
The study was designed to compare the clinical outcomes of these two residual cavity management techniques. Postoperative outcomes included overall postoperative complications, surgical site infection, biliary fistula, and residual cavity-related complications. Operative characteristics and other relevant perioperative outcomes were also evaluated.
All surgical procedures were performed by the same surgical team using a standardized perioperative approach. Patients received albendazole treatment according to the institutional treatment protocol. Following surgery, patients underwent clinical and radiological follow-up using ultrasonography and/or computed tomography as clinically appropriate. Long-term follow-up was used to evaluate recurrence and other relevant clinical outcomes.
The primary objective of the study was to determine whether the method used for residual cavity management was associated with differences in postoperative outcomes after conservative surgery for complicated hepatic cystic echinococcosis.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Participants underwent conservative surgery for complicated hepatic cystic echinococcosis followed by omentoplasty for residual cavity management.
Procedure: omentoplasty
Participants underwent conservative surgery for complicated hepatic cystic echinococcosis followed by external tube drainage for residual cavity management.
Procedure: External Tube Drainage
After conservative surgery for complicated hepatic cystic echinococcosis, the residual cavity was obliterated using a pedicled omental flap (omentoplasty) to reduce dead space and cavity-related complications.
After conservative surgery for complicated hepatic cystic echinococcosis, an external tube drain was placed into the residual cavity for postoperative drainage and monitoring.

Time frame: Up to 30 days after surgery
Postoperative Bile Leakage
Incidence of postoperative bile leakage, defined as clinically evident biliary drainage after surgery, compared between the omentoplasty and tube drainage groups.
