Hepato-thoracic cystic echinococcosis transit. Clinical features, postoperative complications and hospital mortality. A systematic review.

BACKGROUND

Hepato-thoracic hydatid transit (HTT) is an evolutionary complication of hepatic cystic echinococcosis. This study aimed to report the available evidence regarding postoperative complications (POC) and hospital mortality (HM).

METHODS

Systematic review. Studies related to HTT were included. Searches were performed in Trip Database, SciELO, BIREME-BVS, WoS, PubMed, EMBASE and SCOPUS.

PRIMARY OUTCOMES: POC and HM.

SECONDARY OUTCOMES: publication date, origin and designs, number of patients, cyst type, hospital stance, treatments; and methodological quality (MQ) of studies applying MInCir-T and MInCir-Pr2 scales. Descriptive statistics, weighted means (WM) and their comparison using least squares logistic regression, and meta-analysis of prevalence of POC and HM were applied.

RESULTS

604 studies were retrieved (101 met selection criteria, representing 1020 patients). WM age: 42.6 years, 58.3 % male. Reports are mainly from Spain (19.8 %) and Turkey (17.8 %). With a WM of 18.3 days of hospital stance, it was verified 28.9 % of POC, 12.6 % needed re-interventions, and 9.7 % died. MQ of studies: 9.1 ± 1.9 (MInCir-T) and 13.2 ± 2.9 (MInCir-Pr2). Comparing the behavior of variables in two periods (1983-2002 vs. 2003-2024), statistically significant differences were observed in POC, HM, and reinterventions.

CONCLUSION

HTT is associated with high POC, and significant HM, despite the passage of time.
