Analysis of Early and Distant Results of Various Options for Eliminating the Residual Liver Cavity Following Echinococcectomy

Abstract

Introduction. The available literature on the surgery of echinococcosis is mainly presented by retrospective studies, and the results of these studies are often contradictory, especially when it comes to options for the elimination of the residual cavity after removal of the parasitic liver cyst. In this regard, the main purpose of this work is to evaluate the effectiveness of various ways to eliminate the residual liver cavity after echinococcectomy.Materials and methods. The Republican clinical hospital was the host (city of Ufa, Russia) to conduct a prospective analysis of 234 cases of laparotomic surgical removal of echinococcal cysts in the period from 2000 to 2017. The patients were divided into three groups depending on the surgical tactics to solve the problem of residual liver cavity: the first group (n = 84) patients underwent capitonnage and intussusception of the fibrous capsule of the residual cavity; in the second (n = 79) group the greater omental pedicle flap was tamponaded; in the third (n = 71) group underwent the maximum possible excision of the fibrous capsule and the remaining empty space in the liver was opened into the abdominal cavity.Results and discussion: The suppuration of the residual cavity, being the most frequent complication encountered in our study, with almost the same frequency was noted in both groups of patients, where the elimination of the residual cavity was carried out by capitonnage or greater omentum tamponading. According to multifactorial analysis, infectious complications and recurrence of echinococcus were statistically lower in group III than in other groups (p = 0.002 and 0.001; p = 0.004 and p = 0.002).Conclusion. The findings showed that the safest option for “frugal” echinococcectomy was the maximum possible excision of the fibrous cap with subsequent aplatisation. This approach was characterised by the least number of infectious complications and did not require repeated interventions.
