Total laparoscopic hysterectomy - clinical comparison of the method using two types of uterine manipulators.

ABSTRACT

AIM OF THE STUDY Comparison of two types of uterine manipulators used in total laparoscopic hysterectomy (TLH) and clinical evaluation of the method in patients in a two-year group supplemented by subjective evaluation. DESIGN: Prospective observational study. SETTING: Department of Gynecology and Obstetrics, Masaryk University, Faculty of Medicine and University Hospital Brno. MATERIAL AND METHODS: A group of patients operated in the years 2018-2019 by the TLH method using one of two types of uterine manipulators - Karl Storz HOHL (group No. 1) vs. plastic ring of Koh's manipulator (group No. 2). We compared surgical time (min), blood loss (ml), perioperative complications, length of hospital stay (days), early and late complications. We were interested in the possible influence of BMI, uterine on these parameters. Subjective evaluation of the method by patients took place before the procedure and 12 weeks after the operation with a standardized questionnaire. RESULTS: A total of 134 patients were enrolled in the study (75 in group 1 vs. 59 in group 2). The monitored parameters age, BMI, operative time, blood loss and length of hospitalization did not differ statistically significantly. When comparing the individual groups with different manipulators, the total number of complications (mild difficulties, serious complications) was without statistical significance (p = 0.58), but the spectrum of symptoms was different in both groups. More than a third of the patients in the group were obese. There were more serious complications than non-obese ones, the performance was longer, however, for a small number it was statistically insignificant (p = 0.11). In patients with uterine surgery, we recorded more adhesiolysis. We did not show that previous surgery on the uterus was associated with a higher incidence of complications (p = 0.6). We did not notice any statistically significant difference in the subjective evaluation (p = 0.3). CONCLUSION: TLH is the dominant method of uterine removal in our workplace. In a group of 134 women, we did not show a statistically significant difference in the monitored parameters. The HOHL manipulator has proved to be more user-friendly due to its technical parameters and better clarity of the operating field. Subjective evaluation of the method was positive in patients.
