Para-anastomotic aneurysms may have dangerous complications such as rupture and thrombosis, with consequent loss of life. As these complications are associated with high mortality rates, early detection and prompt surgical treatment are important. Repair of para-anastomotic aneurysms may be challenging and the surgical approach should be carefully planned. A 66-year-old man had undergone thoracoabdominal aortic aneurysm repair 18 years previously. The diameter of the distal aortic anastomosis was gradually increasing. We comprehensively discussed the surgical approach preoperatively, including consideration of spinal cord protection. Abdominal aortic graft replacement was performed through a midline abdominal incision, with cross-clamping on the proximal side of the aneurysm, continuous intravenous infusion of naloxone, and segmental aortic clamping with distal aortic perfusion and selective visceral perfusion. The left renal artery was reconstructed, and the inferior mesenteric artery and lumbar arteries were preserved.

In order to study whether there is any relation between the cause of anemia in rural women and environmental factor from the epidemiological standpoint, we have followed up the seasonal change of the blood properties (GB, Hb, Ht, R, Serum iron) of 3 groups of women in different working and living circumstances.
The results revealed a remarkable tendency to increase the values of the blood properties excluding serum iron in winter and to decrease in summer. The degree of seasonal change was found to be greater in rural women than that in factory workers. And among the factory workers, the married had more change than the unmarried, the rural residents than the urban. And among the rural women, only the establishmental gardeners who were especially busy in winter showed a tendency to decrease the values of the blood properties in winter.
From these data, we can see that the seasonal change of the burden of agricultural work and the change of dietary life actually have direct influence on the change of the blood properties.

Objective:
BRCA1 and BRCA2 mutation carriers are recommended to undergo risk-reducing salpingo-oophorectomy (RRSO) by age 40 and 45, respectively. However, the carriers have a different way of thinking about their life plan. We aimed to investigate the distribution of age at diagnosis of ovarian cancer (OC) patients to examine the optimal timing of RRSO in the carriers.
Methods:
We examined a correlation between age at diagnosis of OC and common mutation types in 3,517 probands that received BRCA genetic testing. Among them, germline BRCA1 mutation (gBRCA1m), germline BRCA2 mutation (gBRCA2 m) and germline BRCA wild-type (gBRCAwt) were found in 185, 42 and 241 OC patients, respectively.
Results:
The average age at diagnosis of OC in gBRCA1m and gBRCA2 m was 51.3 and 58.3 years, respectively, and the difference from gBRCAwt (53.8 years) was significant. The gBRCA2 m carriers did not develop OC under the age of 40. The average age was 50.1 years for L63X and 52.8 years for Q934X in BRCA1, and 55.1 years for R2318X and 61.1 years for STOP1861 in BRCA2 . The age at diagnosis in L63X or R2318X carriers was relatively younger than other BRCA1 or BRCA2 carriers, however their differences were not significant. With L63X and R2318X carriers, 89.4% (42/47) and 100% (7/7) of women were able to prevent the development of OC, respectively, when RRSO was performed at age 40.
Conclusion
There appears to be no difference in the age at diagnosis of OC depending on the type of BRCA common mutation. Further analysis would be needed.

OBJECTIVES: Intraoperative tumor manipulation and dissemination may possibly compromise survival of women with early-stage cervical cancer who undergo minimally-invasive radical hysterectomy (RH). The objective of the study was to examine survival related to minimally-invasive RH with a “no-look no-touch” technique for clinical stage IB1 cervical cancer. METHODS: This retrospective study compared patients who underwent total laparoscopic radical hysterectomy (TLRH) with no-look no-touch technique (n=80) to those who underwent an abdominal radical hysterectomy (ARH; n=83) for stage IB1 (≤4 cm) cervical cancer. TLRH with no-look no-touch technique incorporates 4 specific measures to prevent tumor spillage: 1) creation of a vaginal cuff, 2) avoidance of a uterine manipulator, 3) minimal handling of the uterine cervix, and 4) bagging of the specimen. RESULTS: Surgical outcomes of TLRH were significantly superior to ARH for operative time (294 vs. 376 minutes), estimated blood loss (185 vs. 500 mL), and length of hospital stay (14 vs. 18 days) (all, p < 0.001). Oncologic outcomes were similar between the 2 groups, including disease-free survival (DFS) (p=0.591) and overall survival (p=0.188). When stratified by tumor size (<2 vs. ≥2 cm), DFS was similar between the 2 groups (p=0.897 and p=0.602, respectively). The loco-regional recurrence rate following TLRH was similar to the rate after ARH (6.3% vs. 9.6%, p=0.566). Multiple-pelvic recurrence was observed in only 1 patient in the TLRH group. CONCLUSION: Our study suggests that the no-look no-touch technique may be a useful surgical procedure to reduce recurrence risk via preventing intraoperative tumor spillage during TLRH for early-stage cervical cancer.

The Laparoscopic Approach to Cervical Cancer (LACC) trial demonstrated that minimally invasive radical hysterectomy was inferior to the open approach [1]; this unexpected result could be attributed to the spillage of cancer cells [2]. Following the LACC trial, laparoscopic radical hysterectomy without an intrauterine manipulator upon completion of a vaginal cuff closure became the new standard treatment method [3]. However, the lack of intrauterine manipulator results in poor visualization and inadequate paracervical tissue resection. This study describes the no-look no-touch technique to address this difficulty. The core procedures in our no-look, no-touch laparoscopic radical hysterectomy are: (Step 1) Creation and closure of a vaginal cuff; (Step 2) Manipulation of the uterus without an intra-uterine manipulator; and (Step 3) Exposure of the paracervical tissues by the suspension technique. The patient eligibility for our procedure is as follows: 1) previously untreated cervical cancer (those who underwent diagnostic conization could be included); 2) clinical stage IA2, IB1, IB2, and IIA1 based on the 2018 International Federation of Gynecology and Obstetrics staging system; 3) histologically confirmed cervical cancer, including squamous cell carcinoma, adenocarcinoma, and adenosquamous carcinoma. The important indication for this procedure is in cases where the tumor is less than 4 cm in diameter. We previously reported that our no-look no-touch technique enables smooth performance of laparoscopic radical hysterectomy without worsening oncologic outcomes [4]. According to a recent systematic review and meta-analysis [5], minimally invasive radical hysterectomy with vaginal cuff closure is a safe treatment option; however, it involves a steep learning curve, which has impeded its increased application. This video will hopefully make minimally invasive radical hysterectomy with protective maneuvers against cancer cell spillage more accessible. Based on our experiences, we propose that our transvaginal cervical tumor-concealing no-look no-touch technique will mitigate the risk of surgical spill of tumor cells during minimally invasive radical hysterectomy. The informed consent for use of this video was taken from the patient.

Radical hysterectomy is a standard surgery to treat early-stage uterine cervical cancer. The Laparoscopic Approach to Cervical Cancer (LACC) trial has shown that patients receiving minimally invasive radical hysterectomy have a poorer prognosis than those receiving open radical hysterectomy; however, the reason for this remains unclear. The LACC trial had 2 concerns: the learning curve and the procedural effects. Appropriate management of the learning curve effect, including surgeons’ skills, is required to correctly interpret the result of surgical randomized controlled trials. Whether the LACC trial managed the learning curve effect remains controversial, based on the surgeons’ inclusion criteria and the distribution of institutions with recurrent cases. An appropriate surgical procedure is also needed, and avoiding intraoperative cancer cell spillage plays an important role during cancer surgery. Cancer cell spillage during minimally invasive surgery to treat cervical cancer is caused by several factors, including 1) exposure of tumor, 2) the use of a uterine manipulator, and 3) direct handling of the uterine cervix. Unfortunately, these issues were not addressed by the LACC trial. We evaluated the results of minimally invasive radical hysterectomy while avoiding cancer cell spillage for early-stage cervical cancer. Our findings show that avoiding cancer cell spillage during minimally invasive radical hysterectomy may ensure an equivalent oncologic outcome, comparable to that of open radical hysterectomy. Therefore, evaluating the importance of avoiding cancer cell spillage during minimally invasive surgery with a better control of the learning curve and procedural effects is needed.

Objective:
To describe anatomic patterns of the superficial uterine vein (sUV) and assess their association with aspects of the dissection procedure of the anterior layer of the vesicouterine ligament (aVUL) by retrospectively reviewing surgical videos.
Methods:
We analyzed patients who underwent laparoscopic radical hysterectomy for early-stage cervical cancer from 2014 to 2019. The primary endpoint was the time required for aVUL dissection. Multiple linear regression analyses were performed to identify factors influencing the time required for aVUL dissection.
Results:
Fifty-three Japanese patients were included. Two sUV configurations were observed:type 1 (the vein ran ventral to the ureter along the uterine artery) and type 2 (the vein did not run along the usual ventral course; it ran dorsal to the ureter or was absent). Approximately 30% of the sUVs were type 2. The total time for dissection of both sides of the aVUL was significantly shorter for type 2 sUVs than for type 1 sUVs. The number of hemostatic interventions during dissection of each side of the aVUL was significantly lower for type 2 sUVs than for type 1 sUVs. In the multivariate analysis, the sUV configuration was the factor significantly influencing the duration of aVUL dissection on each side (right side: β=−143.4;left side, β=−160.4).
Conclusion
We demonstrated that the sUV had 2 types of courses, ventral and others, and its course affected the time required for dissection and the number of hemostatic interventions.Our results provide information supportive of improved radical hysterectomy outcomes.

Objective:
The combination of cancer and hypercoagulable states is often called Trousseau syndrome. In particular, cerebral infarction caused by Trousseau syndrome is reported to have a poor prognosis. In gynecology, there are many reports of ovarian cancer and a few of uterine cancer. Since there has been no comprehensive report of Trousseau syndrome in cervical cancer, we aimed to summarize Trousseau syndrome in cervical cancer.
Methods:
Cerebral infarction caused by cancer-related arterial thrombosis was defined as Trousseau syndrome. Patients with cervical cancer diagnosed at our hospital between January 2014 and December 2021 were retrospectively reviewed using the hospital’s medical records.
Results:
A total of 1,432 patients were included in the study. Trousseau syndrome occurred in 6 patients (0.4%). The mean age of patients with Trousseau syndrome was 63 years (range:53–78 years). Of the 6 patients who developed Trousseau’s syndrome, 4 patients had it before or during initial treatment, and 2 during recurrent/relapsed disease treatment. The 4 patients who developed the syndrome before or during initial treatment had advanced disease: 1 in stage IIIC and 3 in stage IVB. In all cases, the disease was associated with progressive distant metastasis. The median survival time from the onset of Trousseau syndrome was 1 month (range: 0–6 months).
Conclusion
Cervical cancer causes Trousseau syndrome in cases of advanced disease with a short time between the onset of the syndrome and mortality.
