Abstract
Background
Abdominal hysterectomy has been largely replaced by minimally invasive surgery. Nevertheless, in some situations, a minimally invasive intervention must be converted to laparotomy. Factors associated with conversion to laparotomy are still a matter of debate.
Objective
The aim of this study was to evaluate the clinicopathological factors associated with the conversion of laparoscopic hysterectomy to laparotomy.
Materials and Methods
The risk factors for conversion of a preplanned laparoscopic procedure to laparotomy were retrospectively evaluated in 441 patients undergoing a hysterectomy for a benign indication between 2016 and 2020. Associations between the clinical factors were analysed using Pearson's chi-square and Fisher's exact test, and predictive values for conversion were assessed through multivariate logistic regression.
Result
Conversion occurred in 32 (7.3%) of the cases. Significant differences were detected for uterus weight (576.9gr vs 174.6gr, p<0.001), myoma size (7.0 cm vs. 1.8 cm, p<0.001), and presence of triple diagnosis consisting of leiomyoma, adenomyosis uteri, and pathological adnexal findings (p<0.013). The conversion resulted in prolonged surgery time (181.6 min vs. 119.6 min, p<0.001) and hospital stay (4.0 vs. 3.1 days, p<0.001), as well as an increased rate of wound infection (15.6% vs. 3.4%, p<0.001). A 10g increase in uterus weight raised the risk of conversion by 7.0%, and a 1cm increase in myoma diameter by 7.3%, while adnexal pathologies and extensive adhesions increased the odds of conversion to laparotomy threefold (ORs of 3.2, 1.09-9.6 and 3.6, 1.3-10.0, respectively).
Conclusion
Uterus weight, myoma size, the coexistence of pathological adnexal findings, and non-physiological adhesions are independent risk factors for conversion.
What is new?
This study provides data regarding the risk and factors increasing this risk for conversion to laparotomy during laparoscopic hysterectomy.
