Correlation of diaphragm surgical findings with preoperative CT scans in ovarian cancer

Correlation of diaphragm surgical findings in ovarian cancer patients with and without diaphragm metastases with pre-operative CT diaphragm findings to assess sensitivity and specificity for diaphragm disease. Material and Methods: A retrospective study of 120 ovarian cancer patients (60 with and 60 without diaphragm metastases at surgery), FIGO Stage IIIC or IV, undergoing cytoreductive surgery at Mayo Clinic, Arizona, between January 2000 and October 2014. All patients had preoperative imaging with CT scan of abdomen and pelvis including the lower lung fields. CTs were not reviewed retrospectively. Results: Among 60 patients with diaphragm metastases, preoperative CTs were positive for diaphragm disease in 17 patients, with a sensitivity rate of 28% (CI 95%: 0.17-0.41). All 60 patients with no diaphragm metastases had negative CTs, with a specificity of 100% (CI 95%: 94.0%-100%). When analyzed by lesion size, CTs were negative in 66.7-80% of patients with diaphragm lesions ranging from 1-15 mm. There was a trend towards increased detection rate with increasing size of lesions, but it did not reach significance (p = 0.529). CT detection rate for single metastatic lesion was 18.2% (6/33) and for multiple lesions it was 25.9% (7/27). There was no difference for CT identification of right, left, or bilateral metastases (p = 0.399). The sensitivity and specificity of CT for pleural effusion was 100% (CI 95%: 72.2%-100%) and 88% (CI 95%: 76.2%- 94.4%), respectively. The area under the receiver operating characteristic (ROC) curve was 0.680 (CI 95%: 55.3%-72.2%) for CT detection of diaphragm metastases and 0.957 (CI 95%: 79.9%-95.3%) for pleural effusions. Conclusion: CT has a low sensitivity and a high specificity for the prediction of diaphragm metastases in ovarian cancer. The size, location, and number of diaphragm lesions do not significantly improve CT detection rat

From open radical hysterectomy to robot-assisted laparoscopic radical hysterectomy for early stage cervical cancer: aspects of a single institution learning curve

We analysed the introduction of the robot-assisted laparoscopic radical hysterectomy in patients with early-stage cervical cancer with respect to patient benefits and surgeon-related aspects of a surgical learning curve. A retrospective review of the first 14 robot-assisted laparoscopic radical hysterectomies and the last 14 open radical hysterectomies in a similar clinical setting with the same surgical team was conducted. Patients were candidates for a laparoscopic sentinel node procedure, pelvic lymph node dissection and open radical hysterectomy (RH) before August 2006 and were candidates for a laparoscopic sentinel node procedure, pelvic lymph node dissection and robot-assisted laparoscopic radical hysterectomy (RALRH) after August 2006. Overall, blood loss in the open cases was significantly more compared with the robot cases. Median hospital stay after RALRH was 5 days less than after RH. The median theatre time in the learning period for the robot procedure was reduced from 9 h to less that 4 h and compared well to the 3 h and 45 min for an open procedure. Three complications occurred in the open group and one in the robot group. RALRH is feasible and of benefit to the patient with early stage cervical cancer by a reduction of blood loss and reduced hospital stay. Introduction of this new technique requires a learning curve of less than 15 cases that will reduce the operating time to a level comparable to open surgery

Endometrial cancer

Endometrial cancer is the most common gynecological malignancy in well-developed countries. Biologically and clinicopathologically, endometrial carcinomas are divided into two types: type 1 or estrogen-dependent carcinomas and type 2 or estrogen-independent carcinomas. Type 1 cancers correspond mainly to endometrioid carcinomas and account for approximately 90 % of endometrial cancers, whereas type 2 cancers correspond to the majority of the other histopathological subtypes. The vast majority of endometrial cancers present as abnormal vaginal bleedings in postmenopausal women. Therefore, 75 % of cancers are diagnosed at an early stage, which makes the overall prognosis favorable. The first diagnostic step to evaluate women with an abnormal vaginal bleeding is the measurement of the endometrial thickness with transvaginal ultrasound. If endometrial thickening or heterogeneity is confirmed, a biopsy should be performed to establish a definite histopathological diagnosis. Magnetic resonance imaging is not considered in the International Federation of Gynaecology and Obstetrics staging system. Nonetheless it plays a relevant role in the preoperative staging of endometrial carcinoma, helping to define the best therapeutic management. Moreover, it is important in the diagnosis of treatment complications, in the surveillance of therapy response, and in the assessment of recurrent disease.info:eu-repo/semantics/publishedVersio

The risk of hydrosalpinx formation and adnexectomy following tubal ligation and subsequent hysterectomy: a historical cohort study

OBJECTIVE: The objective of the study was to further investigate a previous finding that tubal sterilization followed by hysterectomy was associated with hydrosalpinx formation. STUDY DESIGN: The Rochester Epidemiology Project (Rochester, MN) was used to identify three cohorts: women who had undergone tubal sterilization and subsequent hysterectomy, women who had undergone tubal sterilization alone, and women who had undergone hysterectomy alone. Four hundred seventy-three charts were reviewed and 337 met inclusion criteria. Patient histories were analyzed prospectively, looking for subsequent adnexal surgery. RESULTS: There was no increased risk of hydrosalpinx formation in patients who had undergone tubal sterilization and hysterectomy, compared with tubal sterilization alone. The proportion of subjects undergoing later adnexectomy for any reason was significantly higher in the hysterectomy groups, compared with the sterilization only group (relative risk 3.5, 95% confidence interval 1.3-9.4). CONCLUSION: This prospective study does not support the previously reported case-control data suggesting that tubal sterilization followed by hysterectomy resulted in an increased risk of hydrosalpinx formation, compared with tubal sterilization alone

The shift from inpatient to outpatient hysterectomy for endometrial cancer in the United States: Trends, enabling factors, cost, and safety

To evaluate trends in outpatient versus inpatient hysterectomy for endometrial cancer and assess enabling factors, cost and safety. In this retrospective cohort study, patients aged 18 years or older who underwent hysterectomy for endometrial cancer between January 2008 and September 2015 were identified in the Premier Healthcare Database. The surgical approach for hysterectomy was classified as open/abdominal, vaginal, laparoscopic or robotic assisted. We described trends in surgical setting, perioperative costs and safety. The impact of patient, provider and hospital characteristics on outpatient migration was assessed using multivariate logistic regression. We identified 41 246 patients who met inclusion criteria. During the time period studied, we observed a 41.3% shift from inpatient to outpatient hysterectomy (p<0.0001), an increase in robotic hysterectomy, and a decrease in abdominal hysterectomy. The robotic hysterectomy approach, more recent procedure (year), and mid-sized hospital were factors that enabled outpatient hysterectomies; while abdominal hysterectomy, older age, Medicare insurance, black ethnicity, higher number of comorbidities, and concomitant procedures were associated with an inpatient setting. The shift towards outpatient hysterectomy led to a $2500 savings per case during the study period, in parallel to the increased robotic hysterectomy rates (p<0.001). The post-discharge 30-day readmission and complications rate after outpatient hysterectomy remained stable at around 2%. A significant shift from inpatient to outpatient setting was observed for hysterectomies performed for endometrial cancer over time. Minimally invasive surgery, particularly the robotic approach, facilitated this migration, preserving clinical outcomes and leading to reduction in costs
