A statistical survey of neoplasms collected from the files of surgical and autopsy specimens examined in the department of pathology during the 52 months preceeding August 1961, was made and the results compared with the previously reported data. The total number of specimens surveyed in this study was 7,978, among which benign neoplasms accounted for 480 cases and malignant neoplasms for 1,107. Carcinomas of the stomach and uterus occupied the highest frequency among the malignant tumors. The incidence of benign tumors of the uterus was significantly higher than that reported by others. A detailed analysis of the various data on benign and malignant tumors is listed in the tables.

OBJECTIVES: Intrauterine adhesions (IUA) refers to the adhesions between the myometrium of the uterine cavity, which is secondary to damage to the basal layer of the endometrium due to trauma or infection. The occurrence of IUA is mainly related to intrauterine operations. Hysteroscopic adhesiolysis (HA) is the standard surgical treatment for IUA. But the recurrence rate of IUA after HA is still high. Importantly, endometrium recovery is difficult, resulting in unsatisfied prognosis for moderate to severer IUA patients. Therefore, it is important to take effective primary preventive measures against the etiology to avoid endometrium damage from medical surgery. In this paper, we discuss and analyze predilection and severer sites of intrauterine adhesions, aiming to provide a basis for how to avoid and reduce injuries during intrauterine operations, such as abortion, dilation and curettage. METHODS: In this study, we retrospectively analyzed the surgical videos of patients who underwent HA for the first time from January 2019 to December 2021 in the Third Xiangya Hospital of Central South University so as to assess the area of adhesions and predilection and severer sites of occurrence of adhesions, and we collected 657 patients who underwent HA for the first time, including 81 patients with total IUA and 576 patients with partial IUA. We counted and analyzed the number and composition ratio of partial IUA patients with severer sites of damage to the lateral wall of the uterine cavity and severerr sites of damage to each segment of the uterine cavity. RESULTS: Among 576 patients with partial IUA, there were 60 patients with no significant difference in the degree of adhesions between the right and left sides, 143 patients with severer adhesions on the left side of the uterine cavity, and 373 patients with severer adhesions on the right side of the uterine cavity. There was a difference in the severity of damage of left and right lateral wall. The proportion of patients with severer adhesions on the right side of the uterine cavity (64.8%) was higher than that of patients with adhesions on the left side of the uterine cavity (24.8%), and there was statistically difference (P<0.05). There was 93 patients with severer adhesions at the fundus or bilateral horn of the uterus, 190 patients with severer adhesions at the middle and upper part of the uterine cavity, 245 patients with severer adhesions at the middle and lower part of the uterine cavity and at the endocervix, and 48 patients with no significant difference in the degree of adhesions in each part. The proportion of patients with severer adhesions at the middle and lower part of the uterine cavity and at the endocervix was higher (42.5%) than those with adhesions in the fundus or bilateral horn of the uterus (16.1%) and in the middle and upper part of the uterine cavity (33.0%), and there were statistically differences (both P<0.05). CONCLUSIONS The predilection site of IUA is the lateral wall of the uterine cavity. The severer adhesions is in the right lateral wall of the uterine cavity, the middle and lower segments and the endocervix, which may be related to the operating habits of the surgeon. Therefore, gynecologists should minimize damage to the lateral wall of the uterine cavity, especially the right lateral wall in performing uterine operations (more attention should be paid by right-handed physicians). Besides, we should pay attention to protecting the middle and lower segments of the uterine cavity and the endocervix, avoiding maintaining negative pressure to withdraw the uterine tissue suction tube from the uterine cavity during abortion procedures to minimize damage.

OBJECTIVES: Although hysteroscopic adhesiolysis (HA) is the main treatment for intrauterine adhesion (IUA), postoperative management of IUA remains challenging because there is no consensus on how to mitigate the high rate of postoperative adhesions reformation. This study aims to compare the effectiveness and safety of 2 types of intrauterine stents with different thickness and hardness in treating moderate-to-severe IUA. METHODS: A retrospective clinical study was conducted in the Third Xiangya Hospital of Central South University from November 2020 to July 2021. A total of 191 patients with moderate-to-severe IUA who received surgical treatment and placed intrauterine stents after HA to prevent recurrence of postoperative adhesions were included. According to the hardness and thickness of the intrauterine stents, the participants were divided into a case group (placed the novel thin intrauterine stent, n=62) and a control group (placed the conventional stent, n=129). After 2-3 menstrual cycles, a second-look hysteroscopy was performed, and the intrauterine stents were removed. The postoperative efficacy [the reduction of American Fertility Society (AFS) scores, the adhesions reformation rate, the changes in menstrual pattern, and the pregnancy rate during the follow-up], safety (the adverse events), and applicability (the difficulty of stent removal) were compared between the 2 groups. RESULTS: No significant differences in preoperative clinical characteristics were observed between the 2 groups (all P>0.05). The menstrual volume of all patients was increased after the treatment. The reduction of AFS scores and the menstruation recovery rate were not significantly different between the 2 groups (P=0.519 and P=0.272, respectively). Notably, there was no case of displacement in the case group, while the displacement rate of the control group was 2.3% (P=0.552). Moreover, there was no significant difference in abdominal pain or postoperative abnormal vaginal bleeding between the 2 groups (P=0.823 and P=0.851, respectively). However, the difficulty rate of removing the thinner stents was significantly lower than that of removing the traditional stent (21.0% vs 38.8%, P=0.014). During the follow-up for half a year of the postoperative period, the pregnancy rate did not differ significantly in the case and control groups (45.0% vs 34.6%, P=0.173). CONCLUSIONS The novel intrauterine stent shows noninferior efficacy and had a good safety profile compared with conventional stents in treating moderate-to-severe IUA. Importantly, it was more convenient to be removed without increasing the rate of displacement and detachment. Therefore, it could reduce the amount of damage to the endometrium and has higher applicability than conventional stents.

OBJECTIVE: To evaluate the clinicopathologic variables that are important for predicting residual disease after cervical conization in hysterectomy specimens. METHODS: We performed retrospective review of 125 patients who had undergone cervical conization and endocervical curettage followed by subsequent hysterectomy. Pathologic findings of the cone margins, endocervical curettage samples, and residual lesions in the postcone hysterectomy specimens were recorded for analysis. RESULTS: The prevalence rates of positive cone margins increased with higher severity of cervical neoplasia. There was a statistically significant difference in the prevalence of residual disease in hysterectomy specimens between patients with positive endocervical margins on cone biopsy(67.3%) and those with negative margins(11.8%) (p<0.01). Most residual lesions in the postcone hysterectomy specimens were similar to cone pathology, however the possibility of more advanced lesions in the uterus was present in patients with positive cone margins. Residual disease was significantly more frequently found in patients with positive endocervical curettage(82.4%)(p<0.01). Especially, when both the endocervical margin and endocervical curettage were positive, residual disease was present in 25 of 28 (89.3%) hysterectomy specimens. CONCLUSIONS: From these results, we concluded that the status of endocervical margin and endocervical curettage have significant predictive value with respect to the presence or absence of residual disease, and final decision in regard to subsequent management should be based on histologic finding of the cone margins and endocervical curettage as well as the patient's age and desire to retain reproductive capability.

OBJECTIVETo evaluate the possibility of vaginal hysterectomy for patients with moderately enlarged uterus of benign lesions.

METHODSOne hundred and seventeen women with benign uterine diseases underwent vaginal hysterectomy. These patients were divided into two groups according to uterine weight. Group I contained 60 patients with uterine enlargement to a weight of 200 to 750 g, and group II contained 57 patients with uterine weight of less than 200 g. Uterine morcellation was performed in some cases. The perioperative data in both groups were analyzed.

RESULTSIn group I, 59 cases underwent transvaginal hysterectomy successfully, except 1 case converted to abdominal operation and the uterine morcellation was performed in 21 women. In group II, all patients successfully underwent transvaginal hysterectomy without any assistance of special technique. The mean uterine weight of group I was significantly heavier than that of group II (280.18 +/- 100.40 g vs 146.48 +/- 35.19 g). The mean operating time was significantly longer for group I than that for group II (83.93 +/- 26.26 minutes vs 35.22 +/- 20.55 minutes). There were no significant differences in blood loss and complications between group I and group II. There was no injury of urinary bladder or rectum, and no vaginal vault infection.

CONCLUSIONSVaginal hysterectomy of moderately enlarged uterus can be safely and effectively performed by experienced operators. In some cases, in order to reduce the uterine volume, uterine morcellation should be used to shorten operative time, reduce the bleeding, and lower the postoperative complications.
