Surgical, oncological and obstetric outcomes of the Shimodaira-Taniguchi conization method.

The present study aimed to investigate the surgical, oncological and obstetric outcomes of the Shimodaira-Taniguchi (S-T) conization method. A total of 858 cases of high-grade intraepithelial lesions treated with S-T conization were retrospectively reviewed, and the surgical, oncological and obstetric outcomes were analyzed. The χ2 test was used to compare the clinical characteristics between patients with and without cervical stenosis. The factors associated with recurrent/persistent disease were analyzed using univariate and multivariate analyses with a Cox hazards regression model. The obstetric outcomes after conization were also evaluated. Cervical stenosis and recurrent/persistent disease occurred in 2.2 and 4.9% of the patients, respectively. Older age [≥45 years; hazard ratio (HR), 3.22; 95% CI, 1.73-6.02] and surgical margin involvement (HR, 6.39; 95% CI, 3.44-11.8) were independently associated with recurrent/persistent disease. In particular, older patients with endocervical margin involvement showed a higher rate of recurrence (3-year recurrence rate, 28.1%). The proportion of patients who experienced cervical stenosis was significantly higher in older patients (0.95 vs. 5.7%; P<0.001). Among the 66 deliveries after conization, term delivery was observed in 62 cases (93.9%). The proportion of patients who experienced preterm delivery after conization was significantly higher in patients with a short interval from conization to conception (P=0.045). In conclusion, the S-T conization method was effective in terms of surgical, oncological and obstetric outcomes. A careful follow-up is required for older patients with positive surgical margins, particularly those with positive endocervical margins. In addition, a short interval of ≤3 months from conization to conception should be avoided to expect term pregnancy.

Total laparoscopic hysterectomy with posterior cul-de-sac obliteration: step-by-step procedures based on precise anatomical landmarks.

BACKGROUND: Dense adhesion due to severe endometriosis between the posterior cervical peritoneum and the anterior sigmoid or rectum obliterates the cul-de-sac and distorts normal anatomic landmarks. Surgery for endometriosis is associated with severe complications, including ureteral and rectal injuries, as well as voiding dysfunction. It is important to develop the retroperitoneal avascular space based on precise anatomical landmarks to minimize the risk of ureteral, rectal, and hypogastric nerve injuries. We herein report the anatomical highlights and standardized and reproducible surgical steps of total laparoscopic hysterectomy for posterior cul-de-sac obliteration. OPERATIVE TECHNIQUE: We approach the patient with posterior cul-de-sac obliteration using the following five steps. Step 1: Preparation (Mobilization of the sigmoid colon and bladder separation from the uterus). Step 2: Development of the lateral pararectal space and identification of the ureter. Step 3: Isolation of the ureter. Step 4: Development of the medial pararectal space and separation of the hypogastric nerve plane. Step 5: Reopening of the pouch of Douglas. CONCLUSION: Surgeons should recognize the importance of developing the retroperitoneal avascular space based on precise anatomical landmarks, and each surgical step must be reproducible.

Total laparoscopic hysterectomy when there is posterior cul-de-sac obliteration: a step-by-step nerve-sparing technique.

Dense adhesions because of severe endometriosis between the posterior cervical peritoneum and the anterior sigmoid or rectum obliterate the cul-de-sac and distort normal anatomic landmarks. Surgery for endometriosis is associated with severe complications, including ureteral and rectal injuries and voiding dysfunction. Surgeons should recognize the importance of not only avoiding ureteral and rectal injuries but also focusing on the preservation of the hypogastric nerves. Herein, we reported the anatomic highlights and surgical steps of laparoscopic hysterectomy for posterior cul-de-sac obliteration with the nerve-sparing technique.

Acute ST-segment elevations following paclitaxel administration for uterine cervical cancer: a case report and literature review.

Paclitaxel-induced cardiac ischemia is a rare but life-threatening complication. Although it may be difficult to distinguish from hypersensitivity or infusion reactions, it should not be overlooked. We herein report a rare case of ST-segment elevation following the administration of paclitaxel for uterine cervical cancer and review the literature regarding paclitaxel-induced cardiac ischemia.A 48-year-old woman with uterine cervical cancer with no cardiovascular risk factors was admitted to our hospital for concurrent chemoradiotherapy (CCRT) and planned to receive weekly paclitaxel and carboplatin for a total of 5 weeks. Just after the completion of the first cycle of paclitaxel infusion, she presented with diaphoresis and her consciousness level decreased. Electrocardiography showed ST elevation, suggesting acute myocardial infarction. Laboratory testing revealed troponin I positivity. Emergency coronary angiography (CAG) revealed a normal coronary artery, suggesting paclitaxel-induced vasospasm. After CAG, the patient was hemodynamically stable and was returned to the gynecologic unit two days after CAG. CCRT without paclitaxel was continued and the patient was uneventfully discharged from hospital.
