Objective:
Minimally invasive radical hysterectomy has a worse prognosis than open surgery, but the reasons for the poor prognosis remain unclear. Tumor spillage occurs when the tumor is exposed to the surgical field and has been suggested to be related to a poor prognosis. This study aimed to compare the prognostic value of tumor spillage in laparoscopic radical hysterectomy and evaluate whether tumor spillage prevention improves oncological safety.
Methods:
We compared the prognosis of patients who underwent laparoscopic radical hysterectomy between December 2014 and November 2021 with or without tumor spillage prevention, including surgeries without prevention and those with failed prevention.Prevention consisted of vaginal cuff formation or closure of the vaginal canal with clips to prevent tumor exposure at the time of colpotomy. The primary endpoint was disease-free survival, which was adjusted using propensity scores to compare patients.
Results:
In total, 165 patients received tumor spillage prevention, and 61 did not or failed to receive such prevention. The median follow-up was 4.4 years. Patients who did not undergo prevention or failed prevention had significantly shorter disease-free survival than those who did (hazard ratio [HR]=3.54; 95% confidence interval [CI]=1.23–10.23). The same trend was observed after adjusting for propensity score matching. Patients who did not or failed to receive prevention were more likely to experience local recurrence (HR=4.01; 95% CI=1.13–14.24).
Conclusion
Tumor spillage prevention was associated with longer disease-free survival in laparoscopic radical hysterectomy.

Laterally extended endopelvic resection (LEER) is a surgical option for patients with laterally recurrent gynecological malignancies to preserve sciatic nerve function [1]. However, when a laterally recurrent tumor involves the sacrum, debulking surgery is generally abandoned because the surgical excision line is outside the standard LEER. Since its technical feasibility and oncological safety have been demonstrated, sacrectomy for recurrent rectal cancer is now considered the treatment of choice [2]. Theoretically, if complete resection is deemed possible, LEER and sacrectomy (beyond-LEER) may be the treatments of choice for recurrent gynecological malignancies. However, the technical feasibility of beyond-LEER has not been reported. In this video, we demonstrate the step-by-step procedure of laparoscopy-assisted beyond-LEER in a patient with platinum-sensitive recurrent ovarian cancer. The patient, with stage IVA ovarian cancer, was in complete remission after debulking surgery and chemotherapy.At the 13-month-platinum-free interval, a solitary recurrent tumor, involving the right internal iliac vessels and infiltrating the right sacral foramen (S3), was detected. Thus, second-line chemotherapy was initially introduced. During 6 months of chemotherapy, the tumor size remained unchanged and no other metastatic lesions were detected. Therefore, surgical resection was planned. Laparoscopy-assisted beyond-LEER was performed, and complete resection without tumor exposure was accomplished. No sign of recurrence 9 months post debulking surgery has been noted. This is the first report to demonstrate the technical feasibility of laparoscopy-assisted beyond-LEER. Table 1 presents a comparison with cases wherein open total pelvic exenteration with low-sacrectomy (TPES) was performed for recurrent rectal cancer. Forty-nine cases of open TPES demonstrated operation time, 11.5 hours; blood loss volume, 2,630 mL; and length of stay, 24.5 days [3]. These results are similar to the findings in our case: operation time, 11 hours; blood loss volume, 1,700 mL; and length of stay, 35 days. We suggest that the benefit of laparoscopy cannot be demonstrated because TPES is a different procedure compared with the beyond LEER.Kimura et al. [4] demonstrated that laparoscopic TPES for recurrent rectal cancer might have a benefit of reduced blood loss. The advantages of laparoscopy during our multidirectional procedure include not only the possibility of reducing blood loss but also the quick closureof abdominal wound and ease of keeping wound clean while changing patient’s position during sacrectomy. However, due to the limited case and follow up periods, further studies are required to determine the efficacy of this novel surgery and real advantage of laparoscopy.The informed consent for use of this video was taken from the patient.

The Professionalism subcommittee of Japan Society for Medical Education has been examining a diverse range of issues related to medical professionalism education for approximately the past 20 years. In July 2015, the committee formulated and presented a draft on “ The Attributes and Competencies of Physicians: An Exploration of Professionalism” Based on this, we have been conducting educational activities on professionalism education, but we had not documented this draft. We are now re-presenting the draft here with minor lexical corrections and additional notes. The professionalism of physicians is delineated in seven attributes and competencies :1. Sense of mission and responsibility towards society2. Practice of patient-centered health care3. Demonstration of integrity and justice4. Acceptance of diverse values and sharing of fundamental values5. Fulfilling roles as leaders/members in organizations and teams6. Pursuit of excellence and lifelong learning7. Self-management and career developmentThis document is presented with the expectation that it will contribute to future discussions on professionalism education.

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.
