Which combination cause less inflammatory response during laparoscopic hysterectomy? Ligasure plus monopolar cautery or harmonic plus bipolar cautery?

OBJECTIVE: We aimed to compare the inflammatory response with alterations in hemogram parameters, in patients who underwent laparoscopic hysterectomy and bilateral salpingo-oophorectomy for benign gynecologic conditions with ligasure plus monopolar cautery or harmonic plus conventional bipolar cautery. METHODS: Patients who underwent Laparoscopic hysterectomy with bilateral salpingo-oophorectomy between January 2017 and January 2022 for benign gynecologic pathology were identified. Patients were divided into two group, according to instruments used during surgery. Instruments were used according to surgeons preference. Preoperative and postoperative in the first 24 hours hematocrit (HCT), WBC, trombocyt, neutrophil- lymphocyte (NLR), platelet-lymphocyte (PLR) ratio, mean platelet volume- lymphocyte ratio (MPVLR) and red cell distribution width- platelet ratio (RPR) values were compared. RESULTS: During study period, a total of 462 patients underwent hysterectomy for benign gynecologic pathology. After exclusion, 212 patients were included in the study. İn the study group, 147 patients were operated with ligasure plus monopolar electrocauter and 65 with harmonic scalpel plus bipolar electrocautery. İn the postoperative period, regardless of the procedure, WBC and RPR count increase, hematocrit and trombocyt decrease in both group but the inflammatory markers lymphocyte count, neutrophyl, NLR, PLR and MPVLR count changed less in the harmonic plus bipolar cautery group which shows less inflamatuar response in this group. CONCLUSIONS: Ligasure plus monopolar cautery group compared with harmonic plus bipolar cautery group cause more inflammatory changes in complete blood count values. However, further studies are needed to show whether these changes in laboratory findings affect clinical situations.
