Retrospective Review of Complications of Liver Hydatid Cyst Surgery with Emphasis on Outcomes of Omentoplasty

Background: the outcome and complications of liver hydatid cyst surgeries with new and old techniques are not well determined. we intended to present the results of operations done for patients with hepatic hydatid cyst in an endemic area. methods: data of 112 patients referred and operated for liver hydatid cyst, in imam kho-meini hospital complex, tehran, iran, from 2015 to 2018, were collected including demo-graphic characteristics, operation parameters and complication related statistics. the varia-bles were presented for different surgical methods including operations with and without omentoplasty. results: patients aged 39. 3 ± 13. 9 yr (70 females; 63. 5%). most frequent clinical com-plaint was vague abdominal pain (n=45; 40. 2%). the most prevalent comorbidity was hy-pertension (18; 16.0%). conservative methods were chosen more frequently including omentoplasty (44; 39. 3%), cyst drainage (27; 24. 1%), cyst resection (19; 17%) and marsu-pialization (3; 2. 7%). overall, 56 patients (50%) were operated with omentoplasty as the single method or in combination with segmentectomy. complications occurred less in pa-tients operated with omentoplasty (41. 1 vs. 23. 2%; p=0. 043); particularly, biloma was more frequent in surgeries without omentoplasty (7. 1 vs 0. 0%; p=0. 042). persistence and recurrence rates were 12. 5% and 3. 6% with relative predilection in, respectively, seg-mentectomy and lobectomy surgical methods compared to omentoplasty. no mortality was recorded. conclusions: in our case series of hepatic hydatid cyst patients, omentoplasty was safe with less complication and similar long-term recurrence rate.
