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.

Intranodal lymphangiography under microsurgery for refractory lymphatic ascites after pelvic lymphadenectomy.

Lymphatic ascites is a postoperative complication of lymph node dissection. Most symptomatic cases improve with conservative treatments. However, optimal management strategies for intractable lymphatic ascites remain controversial, and clinicians sometimes encounter intractable lymphatic ascites that does not respond to conservative management. We herein report a case of postoperative intractable lymphatic ascites that was successfully treated with intranodal lymphangiography (LG) from inguinal lymph nodes under microsurgery. A 56-year-old woman was diagnosed with stage II endometrial cancer and underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy, and pelvic and para-aortic lymphadenectomies. On postoperative day (POD) 13, the patient presented with abdominal distention, and lymphatic ascites was diagnosed. Although the patient was treated with conservative management and lymphaticovenular anastomosis, her lymphatic ascites did not resolve. Finally, intranodal LG from the inguinal region was performed under microsurgery. A 2-cm incision was made on each side of the inguinal region. Once the lymph nodes were identified, a 23-gauge needle was inserted into the lymph node and lipiodol was injected. Extravasation of lipiodol into the abdomen from the left side of the lower pelvic region was confirmed. The postoperative course was uneventful. The ascites gradually decreased and disappeared within two weeks after LG.

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.

Perioperative Serum Creatinine Change and Delayed Urologic Complications Following Total Laparoscopic Hysterectomy for Benign Indications.

Objectives: The objective of the study was to investigate the association between perioperative serum creatinine change and delayed urologic complications following total laparoscopic hysterectomy (TLH) for benign indications. Materials and Methods: A total of 510 cases (503 cases without delayed urologic injuries and 7 cases with delayed urologic injuries) in which TLH was performed for benign indications were retrospectively reviewed. The patient characteristics and surgical outcomes were compared between patients with and without delayed urologic injuries. Laboratory markers (serum creatinine level at the preoperative and postoperative periods, white blood cell [WBC] ratio, and C-reactive protein [CRP] ratio) were analyzed to evaluate the diagnostic value of these laboratory markers. Results: There were no statistically significant differences in age, parity, body mass index, the presence of diabetes mellitus, preoperative GnRH agonist use, previous history of abdominal surgery or the performance of adnexal surgery, ASRM score, the presence of cul-de-sac obliteration, operative time, blood loss or weight of the resected specimens between the two groups. The proportions of patients who showed an elevated creatinine level on postoperative day 1 was significantly higher in the delayed urologic injury group (9.9% vs. 57%, P < 0.001). The combination of the three laboratory markers yielded an area under the ROC curve value of 0.75 (95% confidence interval, 0.491-1) in the detection of delayed urologic injuries. Conclusion: A change in the serum creatine level over baseline after surgery may indicate the possibility of urologic injuries. The combination of creatinine change and other factors, such as WBC or CRP would be helpful for detecting urologic complications after TLH.

Surgical skill and oncological outcome of laparoscopic radical hysterectomy: JGOG1081s-A1, an ancillary analysis of the Japanese Gynecologic Oncology Group Study JGOG1081.

OBJECTIVES: We investigated whether surgical skill and procedure were related to oncological outcomes in cervical cancer patients who underwent Laparoscopic Radical Hysterectomy (LRH). METHODS: We previously assessed data of LRH from 251 patients with FIGO stage (2009) IA2, IB1and IIA1 cervical cancer collected for JGOG 1081s study. 1) The JGOG 1081s cohort study was re-examined to refine the surgical details and extend the follow-up period as chart review. 2) Unedited videos for recurrent cases and matched non-recurrent control cases were newly compared by experts for various surgical skills and surgical procedures using the modified Objective Structured Assessment of Technical Skills (OSATS) tool, without awareness of the recurrence status as video review. RESULTS: After a median follow-up of 46 months, tumors had recurred in 31 of the 251 patients. The five-year Recurrence-Free Survival rate was 86.9% (81.8-90.6) and five-year Overall Survival rate was 93.7% (87.5-96.8). Multivariate analysis from chart reviews found that an experience with LRH of less than 20 cases per institution was an independent prognostic factor for recurrence (Hazard Ratio (HR) 2.49, 95%CI 1.12-5.53, p = 0.025). For the surgical video review, we compared 23 videos of recurrent cases with 23 background-matched non-recurrent controls. Lower modified OSATS scores from the video review were consistently trended to have a higher risk of recurrence. CONCLUSIONS: Our new study has found that LRH surgical experience and skill trended to have better oncological outcomes.

A phase I/II study of GLIF combination chemotherapy for taxane/platinum-refractory/resistant endometrial cancer (GOGO-EM2).

PURPOSE: Development of new treatment strategies for endometrial cancer that has become refractory or resistant to taxane/platinum is a critical need. The present study was a phase I/II study of gemcitabine, levofolinate, irinotecan, and 5-fluorouracil (5-FU) (GLIF) combination chemotherapy to determine optimal dosages, safety, and efficacy. METHODS: Taxane/platinum-resistant or -refractory endometrial disease was defined as tumor progression within 6 months after a taxane/platinum-based regimen. Maximum tolerated dose was investigated by a 3 + 3-designed phase I study. The phase II study was conducted using the recommended doses determined in the phase I study. RESULTS: The dosages recommended for the phase II trial were determined, in the phase I trial, to be: gemcitabine 800 mg/m2, levofolinate 100 mg/m2, irinotecan 80 mg/m2, and 5-FU 1000 mg/m2. Thirty patients were enrolled, including the three patients who received GLIF therapy at the same dose as the recommended phase II dose in the phase I study. Two patients were excluded at this point due to study protocol violations, and the remaining 28 patients were included for analysis. Phase II revealed that the response and disease control rates were 7.1% (2/28) and 39.3% (11/28), respectively, and that the median PFS and OS were 3 months [95% confidence interval (CI) 3-7] and 12 months (95% CI 9-17), respectively. Febrile or grade 4 neutropenia was observed in 14% (4/28) of the cases. Grade 3 or 4 thrombocytopenia was not observed. CONCLUSION: We found that GLIF combination chemotherapy is potentially a useful treatment option for endometrial cancers refractory or resistant to taxane/platinum-based chemotherapy.

Combination chemotherapy with irinotecan and gemcitabine for taxane/platinum-resistant/refractory ovarian and primary peritoneal cancer: a multicenter phase I/II trial (GOGO-Ov 6).

PURPOSE: To develop a new therapeutic strategy for taxane/platinum-resistant/refractory ovarian and primary peritoneal cancers, we evaluated the feasibility and efficacy of irinotecan and gemcitabine combination chemotherapy. METHODS: Patients with taxane/platinum-resistant/refractory cancer received escalating doses of irinotecan and gemcitabine (level 1: 80 and 800 mg/m2, respectively; level 2: 100 and 1000 mg/m2) on days 1 and 8 on a 21-day cycle. Genotyping for UGT1A1*6 and *28 polymorphisms was performed for possible adverse irinotecan sensitivity. RESULTS: A total of 35 patients were enrolled. The recommended dose was defined as 100 mg/m2 irinotecan and 1000 mg/m2 gemcitabine (level 2). The observed common grade 3/4 toxicities were neutropenia (60%), anemia (17.1%), diarrhea (8.6%), thrombocytopenia (5.7%) and nausea (5.7%). Groups homozygous for UGT1A1*6 or *28 were associated with grade 3/4 neutropenia and diarrhea. Objective responses were 20%, including one complete response and six partial responses. In 29 patients treated with the recommended dose, the median progression-free survival and overall survival were 3.8 months (95% CI 2.1-6.0 months) and 17.4 months (95% CI 9.9-21.9 months), respectively, while the 1-year survival rate was 58.6%. CONCLUSIONS: Combination chemotherapy with irinotecan and gemcitabine represents a safe and effective treatment combination for taxane/platinum-resistant/refractory ovarian and primary peritoneal cancers.

A phase II study of postoperative concurrent carboplatin and paclitaxel combined with intensity-modulated pelvic radiotherapy followed by consolidation chemotherapy in surgically treated cervical cancer patients with positive pelvic lymph nodes.

OBJECTIVES: A phase II study was conducted to evaluate the efficacy and toxicity of carboplatin plus paclitaxel (TC)-based postoperative concurrent chemoradiotherapy (CCRT) followed by TC-based consolidation chemotherapy in surgically-treated early-stage cervical cancer patients. METHODS: Women with surgically-treated early-stage cervical cancer with positive pelvic lymph nodes were eligible for this study. The patients were postoperatively treated with pelvic intensity modulated radiotherapy (50.4Gy) and concurrent weekly carboplatin (AUC: 2) and paclitaxel (35mg/m(2)) (TC-based CCRT). Three cycles of consolidation chemotherapy involving carboplatin (AUC: 5) and paclitaxel (175mg/m(2)) were administered after TC-based CCRT. RESULTS: Thirty-one patients were enrolled and treated. Overall, the treatment was well tolerated, and 26 patients (83.9%) completed the planned TC-based CCRT. The most frequently observed acute grade 3/4 hematological toxicities were leukopenia and neutropenia, and diarrhea was the most common acute grade 3/4 non-hematological toxicity. After a median follow-up period of 36.5months, 2 patients (6.5%) had developed recurrent disease. The patients' estimated 3-year progression-free survival (PFS) and overall survival (OS) rates were 88.5% and 93.8%, respectively. In comparisons with historical control groups, TC-based CCRT followed by TC-based consolidation chemotherapy was found to be significantly superior to CCRT involving a single platinum agent in terms of PFS (p=0.026) and significantly superior to extended-field radiotherapy in terms of both PFS (p=0.0004) and OS (p=0.034). CONCLUSIONS: In women with surgically treated early-stage cervical cancer, pelvic TC-based CCRT followed by TC-based consolidation chemotherapy is feasible and highly effective. Future randomized trials are needed to verify the efficacy of this regimen.

Post-partum hypoglycemia and hypothermia as first manifestations of lymphocytic adenohypophysitis: A case report.

Lymphocytic adenohypophysitis is a very rare autoimmune disease characterized by an anterior pituitary infiltration of lymphocytes that cause various symptoms, such as headache, visual disturbance, and hypopituitarism. Lymphocytic adenohypophysitis is more common in women and has a remarkable association with the perinatal period. Recently, we experienced a case of lymphocytic adenohypophysitis shortly after delivery. A 37-year-old primiparous woman delivered her baby at 38 weeks' gestation. The next morning, she presented symptoms of hypoglycemia and hypothermia. Blood testing revealed hypoadrenalism and hypothyroidism. Pituitary magnetic resonance imaging showed characteristic findings consistent with lymphocytic adenohypophysitis. We immediately initiated medication with steroids and levothyroxine. Currently, her pituitary size has normalized and its function has fully recovered. Physical stress resulting from labor and delivery may unmask subclinical lymphocytic adenohypophysitis. Practitioners should keep in mind the possibility of lymphocytic adenohypophysitis in any pregnant women with symptoms of hypoglycemia and hypothermia after delivery.

Definitive radiotherapy for primary vaginal cancer: correlation between treatment patterns and recurrence rate.

The purpose of this study was to determine the outcomes and optimal practice patterns of definitive radiotherapy for primary vaginal cancer. Between 1993 and 2012, 49 patients were treated with definitive radiotherapy for primary vaginal cancer in three hospitals. Of these, 15 patients (31%) had clinically positive regional lymph node metastasis. A total of 34 patients (70%) received external beam radiotherapy with high-dose-rate brachytherapy (interstitial or intracavitary), and 8 (16%) (with small superficial Stage I tumors) were treated with local radiotherapy. The median follow-up was 33 months (range: 1-169 months). The 3-year overall survival (OS), disease-free survival (DFS), and loco-regional control (LRC) rates were 83%, 59% and 71%, respectively. In multivariate analysis, the histological type (P = 0.044) was significant risk factors for LRC. In Federation of Gynecology and Obstetrics (FIGO) Stage I cases, 3 of 8 patients (38%) who did not undergo prophylactic lymph node irradiation had lymph node recurrence, compared with 2 of 12 patients (17%) who underwent prophylactic pelvic irradiation. For Stage III-IV tumors, the local recurrence rate was 50% and the lymph node recurrence rate was 40%. Patients with FIGO Stage I/II or clinical Stage N1 had a higher recurrence rate with treatment using a single modality compared with the recurrence rate using combined modalities. In conclusion, our treatment outcomes for vaginal cancer were acceptable, but external beam radiotherapy with brachytherapy (interstitial or intracavitary) was needed regardless of FIGO stage. Improvement of treatment outcomes in cases of FIGO Stage III or IV remains a significant challenge.

Effect of lymphovascular space invasion on survival of stage I epithelial ovarian cancer.

OBJECTIVE: To evaluate the effect of lymphovascular space invasion on survival of patients with early-stage epithelial ovarian cancer. METHODS: A multicenter retrospective study was conducted for patients with stage IA-C epithelial ovarian cancer who underwent primary comprehensive surgery including lymphadenectomy. Histopathology slides for ovarian tumors were examined by gynecologic pathologists for the presence or absence of lymphovascular space invasion. Survival analysis was performed examining tumoral factors. RESULTS: A total of 434 patients were included in the analysis. Lymphovascular space invasion was detected in 76 (17.5%) patients associated with histology (P=.042) and stage (P=.044). Lymphovascular space invasion was significantly associated with decreased survival outcomes (disease-free survival, 5-year rate 78.4% compared with 90.7%, P=.024 and overall survival, 84.9% compared with 93.2%, P=.031) in univariate analysis. In multivariate analysis, lymphovascular space invasion did not remain a significant variable for disease-free survival (hazard ratio [HR] 1.98, 95% confidence interval [CI] 0.97-3.97, P=.059) or overall survival (HR 2.41, 95% CI 0.99-5.85, P=.052). Lymphovascular space invasion was associated with increased risk of hematogenous and lymphatic metastasis (HR 4.79, 95% CI 1.75-13.2, P=.002) but not peritoneal metastasis (P=.33) in multivariate analysis. Among lymphovascular space invasion-expressing tumors, patients who received fewer than six cycles of postoperative chemotherapy had significantly poorer disease-free survival than those who received six or more cycles (HR 4.59, 95% CI 1.20-17.5, P=.015). CONCLUSION: Lymphovascular space invasion is an important histologic feature to identify a subgroup of patients with increased risk of recurrence in stage I epithelial ovarian cancer. LEVEL OF EVIDENCE: III.

Hand-assisted laparoscopic surgery for a mesenteric teratoma.

Mature cystic teratomas are benign neoplasms of germ cell tumors that occur most frequently in gonadal sites. The tumors usually contain 2 or 3 well-differentiated elements of endodermal, ectodermal, and mesodermal origin. Although relatively uncommon, teratomas can be composed of mature tissue originating from only 1 germ cell layer. This is known as a monodermal teratoma. Extragonadal teratomas, especially mesenteric teratomas, are extremely rare. Currently, only 21 cases of mesenteric teratoma have been described in the English literature. Mesenteric teratomas are rarely diagnosed preoperatively because pathological examination is necessary to make a definitive diagnosis. We herein report a rare case of mesenteric monodermal teratoma and review the literature. To the best of our knowledge, this is the first case of mesenteric teratoma treated with hand-assisted laparoscopic surgery.

Anorectal abscess during pregnancy.

Anorectal symptoms and complaints caused by hemorrhoids or anal fissures are common during pregnancy. It is known that one-third of pregnant women complain of anal pain in the third trimester. Anal pain may be caused by a wide spectrum of conditions, but if it begins gradually and becomes excruciating within a few days it may indicate anorectal abscess. We experienced a case of anorectal abscess during pregnancy which was diagnosed by magnetic resonance imaging and treated by incision and seton drainage at 36 weeks of gestation, followed by a normal spontaneous delivery at 38 weeks of gestation. To our knowledge, this is the first case report of anorectal abscess during pregnancy in the English-language published work. The clinical course of our case and clinical considerations of anorectal abscesses are discussed.

Laparoscopic repair of a post-myomectomy spontaneous uterine perforation accompanied by a bizarre tumor resembling polypoid endometriosis.

Among various long-term complications after previous myomectomy, increasing risk of uterine rupture or dehiscence during pregnancy, and in particular during labor, has been widely recognized. In contrast, the world literature includes no case report of spontaneous uterine perforation or rupture after myomectomy in a nonpregnant woman, and only 1 case of iatrogenic uterine perforation after uterine artery embolization has been reported. Recently, we encountered an extremely rare case of spontaneous uterine perforation after previous myomectomy accompanied by a bizarre tumor resembling polypoid endometriosis, which was successfully treated via laparoscopic surgery. The patient reported genital bleeding and lower abdominal pain. Preoperative magnetic resonance imaging and intraoperative findings clearly demonstrated the presence of a uterine wall defect and a multicystic tumor that had developed from the perforated portion of the uterus. The patient underwent successful laparoscopic surgery for repair of the perforated uterus and resection of the tumor. The clinicopathologic diagnosis of the tumor was tentatively confirmed as an endometriosis-like lesion resembling polypoid endometriosis. We speculate that the cause of the tumor was retrograde menstruation, as in the pathogenesis of endometriosis.

Rupture of renal artery aneurysm during the early post-partum period.

Rupture of renal artery aneurysm associated with pregnancy is an uncommon condition. It is known that almost all previously reported cases have occurred during pregnancy. We experienced a case of rupture of renal artery aneurysm during the early post-partum period which was diagnosed by computed tomography and treated by angiographic embolization. To our knowledge, only two cases of rupture of renal artery aneurysm during the post-partum period have been reported in the English-language published work. An early diagnosis of rupture of renal artery aneurysm during the post-partum period is very challenging because the clinical symptoms of this condition are acute abdominal, flank or back pain, which are relatively common signs caused by more common post-partum complications. However, rupture of renal artery aneurysm is a life-threatening emergency condition requiring prompt diagnosis and treatment. The possibility of a rupture of renal artery aneurysm should be considered in any pregnant women with symptoms of an acute abdomen with hemorrhagic shock.

Angiographic findings after vaginal gauze packing: New insight into an old technique.

We had a transferred case of cervical ectopic pregnancy with hemorrhagic shock at 6 weeks of gestation. Upon arrival at hospital, we performed tight and full vaginal gauze packing to push the uterus upward to control the patient's hemorrhage. Following stabilization of her general condition, she was treated with uterine artery embolization. Using angiography, the effectiveness of vaginal gauze packing for emergency hemostasis by the presumed mechanism of impairing blood flow through the uterine artery was demonstrated. To our knowledge, there are no reports that have previously demonstrated angiographic findings similar to ours after vaginal gauze packing. Vaginal gauze packing is an effective, rapid, and convenient hemostatic procedure able to be carried out in a time-sensitive and challenging situation. As a result, this procedure gives clinicians more time to improve the patients' general status and arrange for transfusion and further definitive treatment.

Complex Müllerian malformation without any present classification: unilateral ovarian and tubal absence with an arcuate uterus.

Müllerian duct anomalies are known to cause infertility and reproductive problems. The true incidence of such abnormalities is not well defined. The most widely accepted method of classification for a Müllerian duct anomaly is the American Society of Reproductive Medicine classification (1988). However, there are some rare anomalies inconsistent with the current classification. Herein, we report a rare case of Müllerian duct anomaly, unilateral ovarian and tubal absence with an arcuate uterus. The failure of the Müllerian ducts to canalize can also lead to the development of a unicornuate uterus and adnexal agenesis. An arcuate uterus indicates incomplete septal absorption after normal fusion of the Müllerian ducts. Therefore, its coexistence with adnexal absence and an arcuate uterus is considered to be extremely unlikely.
