Evaluation of whether there is residual polyp tissue after hysteroscopic morcellation at Cam and Sakura City Hospital: a retrospective cohort study.

BACKGROUND: In polypectomy with mechanical hysteroscopic morcellators, the tissue removal procedure continues until no polyp tissue remains. The decision that the polypoid tissues were removed completely is made based on visual evaluation. In a situation where the polyp tissue was visually completely removed and no doubt that the polyp has been completely removed, short spindle-like tissue fragments on the polyp floor continue in most patients. There are no studies in the literature on whether visual evaluation provides adequate information at the cellular level in many patients in whom polypoid tissues have been determined to be completely removed. The aim of the present study was to analyze the pathological results of the curettage procedure, which was applied following the completion of polyp removal with operative hysteroscopy, and to evaluate whether there was residual polyp tissue in the short spindle-like tissue fragments that the mechanical hysteroscopic morcellator could not remove. The secondary aims of this study were to compare conventional loop resection hysteroscopy with hysteroscopic morcellation for the removal of endometrial polyps in terms of hemoglobin/hematocrit changes, polypectomy time and the amount of medium deficit. METHODS: A total of 70 patients with a single pedunculate polypoid image of 1.5-2 cm, which was primarily visualized by office hysteroscopy, were included in the study. Patients who had undergone hysteroscopic polypectomy were divided into two groups according to the surgical device used: the morcellator group (n = 35, Group M) and the resectoscope group (n = 35, Group R). The histopathological results of hysteroscopic specimens and curettage materials of patients who had undergone curettage at the end of operative hysteroscopy were evaluated. In addition, the postoperative 24th hour Hb/HCT decrease amounts in percentage, the polypectomy time which was measured from the start of morcellation, and deficit differences were compared between groups. RESULTS: In total, 7 patients in the morcellator group had residual polyp tissue detected in the full curettage material. The blood loss was lower in the morcellator group than in the resectoscope group (M, R; (-0.07 ± 0.08), (-0,11 ± 0.06), (p < 0.05), respectively). The deficit value of the morcellator group were higher (M, R; (500 ml), (300 ml), (p < 0.05), respectively). The polypectomy time was shorter in the morcellator group (M, R; mean (2.30 min), (4.6 min), (p < 0.05)). CONCLUSIONS: Even if the lesion is completely visibly removed during hysteroscopic morcellation, extra caution should be taken regarding the possibility of residual tissue. There is a need for new studies investigating the presence of residual polyp tissue.

The Effect of the Number of Breastfeeding Sessions per Day in the Early Postpartum Period on Postpartum Depression Scores Among Pregnant Women Without Risk Factors for Depression: A Retrospective Cohort Study.

Background: The objective of this study was to investigate the relationship between the Edinburgh Postpartum Depression Scale (EPDS) score on the 10th day postpartum and the number of breastfeeding sessions per day among puerperal women (with no known depression risk factors and a low [<10] EPDS score after delivery). Materials and Methods: A total of 1,451 nulliparous, 37- to 41-week pregnant women who gave birth between August 2020 and August 2022 and who underwent routine postpartum checkups on the 10th day after delivery were included in this study. Pregnant women with risk factors for depression before pregnancy, during pregnancy, and after delivery were not included. Patients with an EPDS score of ≥10 after delivery were excluded from the study. On the 10th day after birth, the mean number of breastfeeding sessions per day of the population in the study was determined. Patients with a number of breastfeeding sessions per day above the mean value were classified as Group A (n = 45), and those with values below the mean were classified as Group B (n = 67). Results: The mean number of breastfeeding sessions per day was 10.15. The EPDS scores of Group A (6 [0-19]) were significantly lower than those of Group B (8 [0-20]) (p < 0.05). A negative linear relationship was found between the number of breastfeeding sessions per day and the EPDS scores on the 10th day postpartum (p < 0.05). No statistically significant difference was found between the EPDS scores and the education status, age, or gestational week of the patients (p > 0.05). There was no statistically significant difference between the number of breastfeeding sessions per day and the education status or age of the patients (p > 0.05). Conclusions: Higher number of breastfeeding sessions per day is associated with less risk of maternal postpartum depression. There is a need for new studies on the consequences of the number and quality of breastfeeding sessions.

The effects of 3D/Full HD and 2D/Ultra HD imaging systems on suturing skills during total laparoscopic hysterectomy: a prospective cohort study.

PURPOSE: 2D/Ultra HD and 3D/Full HD imaging systems can provide surgeons with more accurate and detailed views of the surgical site. We aimed to compare the effects of 2D/Ultra HD and 3D/Full HD laparoscopy systems on laparoscopic suturing skills during total laparoscopic hysterectomy. METHODS: In this prospective cohort study, patients were recruited from a tertiary hospital, and demographic data and surgical data were recorded. The primary outcome measures were the durations of the total operation and vaginal cuff closure. Secondary outcome measures were colpotomy duration, total number of sutures placed, duration of first, second, third and fourth sutures, mean suturing duration, total operation duration, the surgeon's perception of difficulty during the vaginal cuff suturing and complications. RESULTS: The 3D/Full HD (n = 39) and 2D/Ultra HD (n = 42) groups were compared in terms of age, BMI, number of previous abdominal surgeries, number of previous cesarean sections, and type of delivery were examined. Both groups were considered homogeneous. The 3D/Full HD group was found to be superior in terms of colpotomy duration, duration of the first, second, and third suture, mean suturing duration, vaginal cuff closure duration, and difficulty of use compared to 2D/Ultra HD group (p < 0.05 for all). CONCLUSION: In conclusion, the use of 3D/Full HD laparoscopy systems can lead to improved surgical outcomes in terms of colpotomy duration, duration of the first, second, and third suture, mean suturing duration, vaginal cuff closure duration, and difficulty of use compared to 2D/Ultra HD systems.

Effects of melatonin on uterine hypertrophy/hyperplasia: A preliminary experimental rat study.

Endometrial hyperplasia is a process of endometrial proliferation that results in a thickening of the endometrial tissue. Melatonin might be able to change the pathophysiological process and prognosis into a positive way that might prevent and heal endometrial hyperplasia, which is the first stage of endometrial cancer. For this perspective, we tried to investigate the effect of melatonin on uterine hypertrophy/hyperplasia in an experimental rat model. Forty Wistar-Albino rats were undergone bilateral oophorectomy and randomized into four groups. To create a model of uterine hypertrophy/hyperplasia in all groups, except the control group [C] (n = 10), 4 mg/kg/day estradiol hemihydrate were given for 14 days. The uterine hypertrophy/hyperplasia was evaluated histopathologically in the left uterine horns, then the groups were treated for 14 days as follows; melatonin (10 mg/kg/day/po) [M] (n = 10), melatonin + estradiol hemihydrate (10 mg/kg/day/po and 4 mg/kg/day/po) [M + E] (n = 10), and dark environment [D] (n = 10). Finally, the effects of the melatonin were examined histopathologically in the right uterine horns. An uterine hypertrophy/hyperplasia model was established in all groups compared to the control group (p < 0.05). In the [M] and [M + E] groups, epithelial cell height and luminal epithelial cell height significantly decreased (41µm vs 12µm, p = 0.005; 14µm vs 10µm, p = 0.005, respectively for [M] group) and (32µm vs 14µm, p = 0.012; 17µm vs 10µm, p = 0.017, respectively for [M + E] group). The [D] group exhibited a significant decrease in epithelial cell height (33µm vs 20µm, p = 0.017). With or without estrogen exposure, melatonin-treated and physiologically melatonin-released rats experienced a significant uterine hypertrophy/hyperplasia recovery. Melatonin may have protective effects on endometrial hyperplasia.
