One-stop clinical assessment of risk for endometrial hyperplasia (OSCAR-Endo): a fast-track protocol for evaluating endometrial pathologies.

PURPOSE: To evaluate a one-stop clinical assessment of risk for assessing endometrial pathologies (OSCAR-Endo), consisting of a fast-track protocol with hysteroscopy, dilation and curettage (D&C) with intraoperative frozen section analysis of the removed tissue in cases of hysteroscopic suspicion of malignancy. METHODS: In this prospective clinical trial, a total of 304 consecutive women with sonographically suspected endometrial hyperplasia and/or postmenopausal bleeding, underwent D&C with intraoperative frozen section analysis between May 2013 and September 2015. Based on the results of the hysteroscopy and/or frozen section, the OSCAR-Endo score was reported: negative, when no frozen section was regarded necessary or the frozen section yielded a negative result; equivocal, when the frozen section reported an equivocal result; positive, when frozen section reported either complex hyperplasia with atypia or cancer. RESULTS: Frozen sections were required by the surgeons in 59 (19.4%) of cases. When compared with the final histology after D&C, frozen section showed a sensitivity, specificity, PPV, NPV, and overall test accuracy of 91.3, 100, 100, 94.1, and 96.3% for predicting malignant disease, respectively. The OSCAR-Endo score showed a sensitivity, specificity, PPV, NPV, and overall test accuracy of 84, 100, 100, 98.6, and 98.7% for predicting malignant disease, respectively. CONCLUSION: The OSCAR-Endo protocol is easy to perform in daily clinical practice reaching an excellent test accuracy. It helps in immediate postoperative counseling of affected patients.

Compartment syndrome after gynecologic laparoscopy: systematic review of the literature and establishment of normal values for postoperative serum creatine kinase and myoglobin levels.

PURPOSE: To evaluate published evidence in the literature on compartment syndrome (CS) in association with gynecologic surgery and to establish postoperative normal values for serum creatine kinase (CK) and myoglobin. METHODS: The present study consists of a case report of a patient with CS, a systematic review including 37 studies and 86 patients with CS, and a retrospective cohort study of 300 patients undergoing various types of laparoscopy for benign or malignant diseases in order to establish postoperative normal values. RESULTS: We report on a patient with early-stage ovarian cancer, who developed CS after laparoscopic surgery with massively elevated serum CK and myoglobin levels, i.e., 1109 U/L and 18151 µg/L, respectively. In our systematic review, median serum CK and myoglobin levels among women with CS were 19,223 (177-27,412) U/L and 1248 (285-1360) µg/L, respectively. In our cohort study, the median postoperative serum CK and myoglobin levels were 68 (14-1576) U/L and 45 (14-1040) µg/L, respectively. The 95th and 99th percentile of serum CK and myoglobin levels were 158 and 391.5 U/L, and 152.3 and 298.9 µg/L, respectively. CONCLUSION: Markedly elevated postoperative serum levels of CK and myoglobin levels might raise the suspicion for CS and could therefore aid in the rapid diagnosis of CS.
