Primary and recurrent serous borderline tumors during pregnancy: a case report and literature review.

The diagnosis and management of borderline ovarian tumors during pregnancy are still not standardized, because these tumors are rarely encountered. We report the case of a 27-year-old pregnant woman who presented with an ovarian mass in her first trimester. Magnetic resonance imaging revealed a multilocular cystic component with papillary lesions in the background of endometriosis, suggesting a seromucinous borderline tumor or ovarian cancer. A right salpingo-oophorectomy and partial omentectomy were performed at 7 weeks of gestation. Pathological examination demonstrated a serous borderline tumor. The subsequent pregnancy course was uneventful, and she gave birth to a healthy baby at 39 weeks of gestation. She wanted to retain fertility, and close follow-up was performed. Four years later, she became pregnant, and a lesion suggesting recurrence in the left ovary was detected. An abdominal left ovarian cystectomy was performed at 13 weeks of gestation, which demonstrated recurrence of the serous borderline tumor. She gave birth to a healthy baby at 39 weeks of gestation. Two months after delivery, she underwent total abdominal hysterectomy with left salpingo-oophorectomy, which revealed no malignant findings. We also reviewed 10 reports that included 58 cases of borderline ovarian tumors diagnosed during pregnancy. The borderline ovarian tumors diagnosed during pregnancy exhibited different characteristics according to each subtype, suggesting the importance of diagnosing borderline ovarian tumor subtypes preoperatively.

Colonic distention and patient acceptance of CT colonography: supine/prone vs left/right lateral scanning.

OBJECTIVE:: To prospectively evaluate and complete the colonic distention and patient acceptance of CT colonography (CTC) in the supine/prone and left/right lateral positions. METHODS:: A total of 220 consecutive patients were alternately allocated to the supine/prone positioning or left/right lateral positioning group. Two readers scored the degree of colonic distention by segment using a 4-point Likert scale (4 = optimal, 3 = adequate, 2 = inadequate, 1 = collapsed). In addition, patients were asked to rate the discomfort due to positioning during each scan using a 3-point animated face scale (3 = difficult, 2 = somewhat unacceptable, 1 = easy). RESULTS:: The overall mean colonic distention scores for supine, prone, left lateral, and right lateral positions were 3.16, 3.29, 3.22, and 3.42, respectively. Of all, the right lateral position provided the best colonic distention (p < 0.01). Combined left lateral and right lateral positions provided more adequately distended segments compared with combined supine and prone positions (95.6% vs 90.7 %, respectively, p < 0.01). Patient acceptance was significantly lower in the prone position compared to other positions; however there was no difference in patient acceptance between the supine and left/right lateral positions. CONCLUSION:: Right lateral positioning provided the best colonic distention and good patient acceptance. ADVANCES IN KNOWLEDGE:: The left/right lateral position should be considered for routine CTC positioning protocols.

Two cases of recurrent uterine cervical cancer with arterio-enteric fistula treated by femoro-femoral artery bypass in hybrid operation room.

Little has been reported regarding aortic-enteric fistula (AEF) as a complication of gynecologic cancers because of its rarity. However, since it is lethal if left untreated, medical practitioners involved with gynecologic diseases should be aware of this deadly condition. In our hospital, we encountered two cases of cervical cancer complicated by AEF. In both cases, contrast computed tomography (CT) revealed leakage of the contrast material from an artery into the small intestine, indicating AEF. Endovascular procedures with complete embolization of the affected arteries and femoro-femoral artery bypass (f-f bypass) were performed in the hybrid operation room. The activities of daily living improved dramatically for both patients, and they survived for 3 months before dying from cervical cancer. While embolization by endovascular methods and f-f bypass performed in a hybrid operation room is, therefore, an available option for treating AEF, literature is lacking and more research is required to improve long-term outcomes for this disease.
