Introduction To this day, performing routine appendectomy for borderline and malignant mucinous ovarian tumors still remains a dilemma. This study aims to determine the survival rate, recurrence rate and complication rate among patients diagnosed with borderline and malignant mucinous ovarian tumor who underwent complete surgical staging with appendectomy.

Methods All studies retrospective studies with histopathologic diagnosis of borderline or malignant MOT with subjects who underwent appendectomy during primary surgery including encompassing data on survival rate, recurrence rate and/or complication rate that matched the terms set by the researchers were retrieved. Review Manager Version 5.3 (Revman 5.4.1) was used by the researcher to perform the systematic review and meta-analysis of included studies.

Results The random interval for survival rate is 64.9 to 99.7% with a P-value of <0.1. The prediction interval for recurrence rate is 0 to 100% with 95% confidence interval. The odds of complications occurring is less than 0.69 to 2.99 times with 95% confidence interval with mean effect size is 0.083 with a 95% confidence interval of 0.027 to 0.23.

Conclusion/Implications The mean prevalence of abnormal histology of the appendix in patients diagnosed with borderline and malignant MOT and underwent routine appendectomy is 3–13%. There is no statistically significant difference in survival rate of patients who were diagnosed with borderline and malignant MOT with or without appendectomy during primary surgery. The prediction interval for recurrence rate is 0 to 100% with 95% confidence interval. There is no significant difference between the rate of complications in patients who underwent appendectomy and those without.
