Abdominal echinococcosis: outcomes of conservative surgery.

BACKGROUND

Hydatid disease, infection with the larval stage of the cestode Echinococcus spp., represents a substantial disease burden worldwide. We report here the outcomes of conservative surgery in patients with abdominal echinococcosis.

METHODS

We carried out a retrospective review of patients who underwent conservative surgery for abdominal hydatid disease during the period January 2008 to December 2011. Perioperative outcomes were analysed after a mean follow-up of 24 months (range 6-36 months).

RESULTS

Thirty patients (mean age 40.4 years; male:female=7:3) underwent surgery. Most (29 patients) had a hepatic hydatid cyst and underwent partial cystectomy with omentoplasty; surgery was open in 22 cases (73%), laparoscopic in six cases (20%) and laparoscopic converted to open in one case (3%); one patient with a splenic cyst underwent open splenectomy. Cystobiliary communication was present in 10 cases (3%). Postoperative complications included transient biliary leak in two cases (7%), grade 1 surgical site infection in five cases (17%) and respiratory tract infection in three cases (10%), with no mortality. Mean hospital stay was 17 ± 9.2 days. None of the patients had recurrence of disease on follow-up imaging.

CONCLUSION

Conservative surgery offers an effective approach for abdominal echinococcosis, with minimal morbidity or recurrence, and is an alternative to radical procedures.
