RESUMO
Background: Laparoscopic surgery is associated with more favorable clinical outcome than conventional open surgery. This might be related to the magnitude of tissue trauma and tissue stress response. This study compares the intensity of tissue injury by assessing plasma C-reactive protein (CRP), lactic dehydrogenase (LDH), and cancer antigen 125 (CA 125) in patients undergoing laparoscopic hysterectomy compared to abdominal hysterectomy.Methods: This study was conducted at Ain Shams University Maternity Hospital from May 2018 to February 2020. 74 women candidate for hysterectomy were recruited and randomized into two groups: group A included 37 cases who underwent abdominal hysterectomy, and group B included 37 cases that underwent laparoscopic hysterectomy.Results: CRP, LDH and CA125 significantly increased post-operatively in both groups. Postoperative mean serum CRP, LDH and CA125 were significantly higher in the laparotomy group (10.84±2.47, 262.21±76.77, and 13.41±2.6 respectively) compared to laparoscopy group (7.92±2.25, 148.53±43.56, 11.79±2.77 respectively) (p<0.05).Conclusions: Surgery is a significant cause of tissue injury that can be assessed by specific markers. We suggest that laparoscopic surgery causes less tissue damage as assessed by lower postoperative CRP and LDH values, which might account for the earlier recovery and reduced hospital stay in laparoscopic surgery.
RESUMO
Objective: To evaluate the relation between uK (uterine Killer) cells and unexplained repeated miscarriage (RM). Patients and Methods: Eighty (80) women with unexplained repeated miscarriage and missed miscarriage of current pregnancy were studied. Fetal viability and gestational age of current pregnancy were confirmed by ultrasound, followed by suction evacuation to collect abortus specimens and uterine wall curettage to collect decidua specimens. Abortus specimens were collected for long-term monolayer cell culture and subsequent chromosome analysis using conventional G-banding technique. Decidua specimens were subjected to IHC (Immunohistochemical) staining using monoclonal antibodies specific to CD56+ and CD16+ expressed by uK cells. Results: CD56+ CD16+ uK cells was found in 85% (68/80) of studied decidua specimens of women with unexplained repeated miscarriage, 88.5% (54/61) had normal abortus karyotyping and 73.7% (14/19) had abnormal abortus karyotyping. 73.75% (59/80) of studied women with past history of early miscarriage had CD56+ CD16+ uK cells in their decidua specimens and 66.25% (53/80) of studied women with past history of late miscarriage had CD56+ CD16+ uK cells in their decidua specimens, the association between early and late miscarriage and CD56+ CD16+ uK cells in deciduas specimen was significant. Conclusion: CD56+ CD16+ uK cells were predominant in decidua specimens of studied women with repeated miscarriage. Significant association was found between presence of CD56+ CD16+ uK cells in studied decidua specimens and unexplained repeated miscarriage.
