Risk factors of postoperative morbidity in patients with uncomplicated liver hydatid cyst

Textbook outcome in the surgical treatment of liver hydatid cyst

BACKGROUND

Textbook outcome is a composite measure used in surgery to define the ideal postoperative period and to assess the quality of care. The aim of this study was to analyze the incidence of textbook outcome and the factors independently associated with its achievement following surgical treatment of liver hydatid cysts.

METHODS

Retrospective cohort study of patients operated on for liver hydatid cysts between January 2006 and December 2021. Textbook outcome was achieved when all the following criteria were fulfilled: no mortality within 90 days, no major complications within 90 days, no hospital readmission within 90 days, and no prolonged hospital stay. Univariable and multivariable analyses were performed to identify factors associated with textbook outcome.

RESULTS

During the study period, 296 patients underwent surgery. Textbook outcome was recorded in 65.9% (195/296). Female gender (odds ratio 2.02; P = .010), noncomplicated cyst (odds ratio 3.97, P < .001), and radical surgery (odds ratio 2.26, P = .003) were the variables associated with a higher probability of achieving textbook outcome.

CONCLUSION

Textbook outcome may be a useful measure to assess the variations in surgical management between different centers, and to improve quality of care after liver hydatid cysts resection.

Pattern of Relapse in Hepatic Hydatidosis: Analysis of 238 Cases in a Single Hospital

INTRODUCTION

Hydatidosis is a chronic disease that is endemic and prevalent in certain regions of the world. Surgical treatment is the best option, although its main problem is that there is a high rate of recurrence. The objective of the present study was to assess its therapeutic management and the factors related to its postoperative morbidity and relapse.

MATERIAL AND METHODS

A descriptive and retrospective study was made of 238 patients with hepatic hydatidosis operated from January 2006 to December 2017 at our center. An analysis was made of the variables associated with postoperative morbidity and relapse, and of the temporal pattern of that relapse.

RESULTS

Out of 238 patients, radical surgery was performed in 132 (55.5%) and partial cystectomy in 106 of them (44.3%). The postoperative morbidity was 42% (100/238) and the relapse rate was 7.2% (17/238). The factors associated with greater postoperative morbidity were partial cystectomy (OR, 2.83 (1.47-5.43); p = 0.002), ≥ 2 cysts (OR, 3.22 (1.51-6.86); p = 0.002), and biliary fistula (OR, 4.34 (2.11-8.91); p < 0.0001); and those associated with higher relapse rate were history of hydatidosis (OR, 4.98 (1.76-14.11); p = 0.003) and ≥ 2 cysts (OR, 3.23 (1.14-9.11); p = 0.027). The first relapses appeared after 14 months, with the greatest incidence between 14 and 36 months.

CONCLUSIONS

The surgical procedure applied is associated with morbidity but not with that of relapse. The observed relapse pattern demonstrates the need to maintain long-term follow-up, but with no follow-up being necessary in the first year. Broader multicenter and prospective studies are needed to establish more precise recommendations.

Radical versus conservative surgical treatment of liver hydatid cysts: a meta-analysis

To date, the efficacy of radical surgery (RS) versus conservative surgery (CS) for liver hydatid cysts (LHC) remains controversial. This meta-analysis was conducted to compare the two interventions. PubMed, Embase, and Web of Science were searched from their inceptions until June 2016. Meta-analysis was performed using STATA 12.0 software. We identified 19 eligible studies from 10 countries by retrieval. In total, 1853 LHC patients who received RS were compared with 2274 patients treated by CS. The risk of postoperative overall complication, biliary fistula, and recurrence was significantly lower, and operation time was significantly longer in the RS group. However, no statistically significant differences were found in terms of mortality risk and the duration of hospital stay between RS and CS. No significant publication biases were observed in all the above analyses. In conclusion, RS reduces the rates of postoperative complications and recurrence, whereas no trend toward such a reduction in mortality was observed in LHC patients.
