BACKGROUND
Robotic-assisted surgery has been used in Ontario hospitals for over a decade, but there is no public funding for the robotic systems or the disposables required to perform robotic-assisted surgeries ("robotics disposables"). We conducted a health technology assessment of robotic-assisted hysterectomy (RH) for the treatment of endometrial cancer in people with obesity. Our assessment included an evaluation of the effectiveness, safety, and cost-effectiveness of RH, as well as the 5-year budget impact for the Ontario Ministry of Health of publicly funding RH. It also looked at the experiences, preferences, and values of people with endometrial cancer and obesity, as well as those of health care professionals who provide surgical treatment for endometrial cancer.
METHODS
We performed a systematic literature search of the clinical evidence to identify systematic reviews and randomized controlled trials relevant to our research question. We reported the risk of bias from the included systematic review. We assessed the quality of the body of evidence according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Working Group criteria. We performed a systematic economic literature search. We also analyzed the 5-year budget impact of publicly funding RH (including total, partial, and radical procedures) for people with endometrial cancer and obesity in Ontario. To contextualize the potential value of RH for people with endometrial cancer and obesity, we spoke with people with lived experience of endometrial cancer and obesity who had undergone minimally invasive surgery (either laparoscopic hysterectomy [LH] or RH), and we spoke with gynecological cancer surgeons who perform hysterectomy.
RESULTS
We included one systematic review in the clinical evidence review. An indirect comparison showed that conversion rates to open hysterectomy (OH) were similar for LH and RH in patients with a body mass index (BMI) ≥ 30 kg/m (6.5% vs. 5.5%, respectively) (GRADE: Very low). An indirect comparison within a subset of patients with a body mass index (BMI) ≥ 40 kg/m showed that a higher proportion of patients who underwent LH required conversion to OH compared with patients who underwent RH (7.0% vs. 3.8%, respectively) (GRADE: Very low). Rates of perioperative complications were similarly low for both LH and RH (≤ 3.5%) (GRADE: Very low). We identified two studies that met the inclusion criteria of our economic literature review. The included economic studies found RH to be more costly than OH or LH for endometrial cancer; however, because these studies were conducted in other countries, the results were not applicable to the Ontario context. Assuming a moderate increase in the volume of robotic-assisted surgeries, our reference case analysis showed that the 5-year budget impact of publicly funding RH for people with endometrial cancer and obesity would be $1.14 million. The budget impact analysis results were sensitive to surgical volume and the cost of robotics disposables. The people we spoke with who had lived experience of endometrial cancer and obesity, as well as gynecological cancer surgeons, spoke favourably of RH and its perceived benefits over OH and LH for people with endometrial cancer and obesity.
CONCLUSIONS
Compared with LH, RH is associated with fewer conversions to OH in patients with endometrial cancer and obesity (i.e., those with a BMI ≥ 40 kg/m). Rates of perioperative complications were similarly low for both LH and RH. The cost-effectiveness of RH for people with endometrial cancer and obesity is unknown. We estimate that the 5-year budget impact of publicly funding RH for people with endometrial cancer and obesity would be $1.14 million. People we spoke with who had lived experience of endometrial cancer and obesity reported favourably on their experiences with minimally invasive hysterectomy (either LH or RH) and emphasized the importance of the availability of safe surgical options for people with obesity. Gynecological surgeons perceived RH as a superior alternative to OH and LH for people with endometrial cancer and obesity.

INTRODUCTION AND IMPORTANCE
Report of an extremely rare case of triple Mullerian anomaly consisting of cervical agenesis, partial vaginal agenesis and complete bicorporeal uterus with functioning endometrium associated with adenomyosis and pelvic endometriosis in a young girl managed with hysterectomy of both uterine horns and excision of pelvic endometriosis.
PRESENTATION OF CASE
A 20-year-old young woman presented with primary amenorrhoea and severe cyclical pain abdomen. She was diagnosed with a rare triple Mullerian anomaly consisting of cervical agenesis, partial vaginal agenesis and complete bicorporeal uterus with functioning endometrium associated with adenomyosis and pelvic endometriosis. She had undergone laparoscopic hematosalpinx drainage in an outside setting which provided her a temporary relief from symptoms. After an accurate pre-operative diagnosis of her condition, she underwent hysterectomy of both uterine horns as both the horns were grossly adenomyotic with hematometra.
DISCUSSION
This case is unique as two different developmental anomalies agenesis and lateral fusion defect were found together leading to a triple Mullerian anomaly with co-existing adenomyosis and endometriosis. Conservative surgery in this particular case had high probability for developing obstruction, sepsis or pelvic abscess later or repeat procedures/surgeries leading to increased morbidity. She was given the option for oocyte freezing along with gestational surrogacy if she desired fertility in future.
CONCLUSION
Early diagnosis and tailored intervention of Mullerian anomalies is essential to improve patients' quality of life. Definitive surgery in the form of hysterectomy should be considered if there are associated pathologies such as adenomyosis and endometriosis and findings such as hematometra.

Surgical Case Reports Aug 2019A case of gastrointestinal stromal tumor (GIST) coexisting with disseminated peritoneal leiomyomatosis (DPL) is rare. We report a case of GIST coexisting with DPL.
BACKGROUND
A case of gastrointestinal stromal tumor (GIST) coexisting with disseminated peritoneal leiomyomatosis (DPL) is rare. We report a case of GIST coexisting with DPL.
CASE PRESENTATION
A 50-year-old woman underwent exploratory laparoscopy under a preoperative diagnosis of gastric GIST with an ovarian tumor or peritoneal dissemination in the pelvic space. Laparoscopy showed multiple peritoneal masses in the pelvic space. Intraoperative frozen sectioning of the pelvic tumors showed multiple spindle cells, suggesting leiomyomas or retroperitoneal tumors; however, it was difficult to rule out peritoneal dissemination from GIST. No disseminated lesion was noted near GIST, and hence, we believed that GIST and pelvic lesions had different origins. We achieved R0 resection by partial resection of the stomach, total hysterectomy, and bilateral salpingo-oophorectomy. The postoperative immunohistopathological examination confirmed the final diagnosis of GIST and DPL. The patient has been recurrence free for 10 years.
CONCLUSIONS
Immunohistochemical examination is essential for correct diagnosis for GIST and DPL. R0 curative resection should be scheduled after immunohistochemical examination of specimens obtained from exploratory laparoscopy.

BACKGROUND
Conversion rates during minimally invasive surgery are generally examined in the limited scope of a particular procedure. However, for a hospital or payor, the cumulative impact of conversions during commonly performed procedures could have a much larger negative effect than what is appreciated by individual surgeons. The aim of this study is to assess open conversion rates during minimally invasive surgery (MIS) across common procedures using laparoscopic/thoracoscopic (LAP/VATS) and robotic-assisted (RAS) approaches.
STUDY DESIGN
Retrospective cohort study using the Premier Database on patients who underwent common operations (hysterectomy, lobectomy, right colectomy, benign sigmoidectomy, low anterior resection, inguinal and ventral hernia repair, and partial nephrectomy) between January 2013 and September 2015. ICD-9 and CPT codes were used to define procedures, modality, and conversion. Propensity scores were calculated using patient, hospital, and surgeon characteristics. Propensity-score matched analysis was used to compare conversions between LAP/VATS and RAS for each procedure.
RESULTS
A total of 278,520 patients had MIS approaches of the ten operations. Conversion occurred in 5% of patients and was associated with a 1.77 day incremental increase in length of stay and $3441 incremental increase in cost. RAS was associated with a 58.5% lower rate of conversion to open surgery compared to LAP/VATS.
CONCLUSION
At a health system or payer level, conversion to open is detrimental not just for the patient and surgeon but also puts a significant strain on hospital resources. Use of RAS was associated with less than half of the conversion rate observed for LAP/VATS.

Metastatic ovarian tumours are extremely rare. The commonest primary site is usually stomach and the metastasis from this site is termed as krukenberg tumour. It accounts for 1-2% of malignant ovarian tumours. We present a case of 14 weeks' pregnancy with metastatic bilateral malignant ovarian tumour is presented. Diagnosis was made on ultrasound. Tumour markers were insignificant. Patient underwent staging laparotomy with total abdominal hysterectomy and bilateral salpingo oophorectomy and partial omentectomy. She also had haematemesis. Endoscopy revealed suspicious growth in stomach, but biopsy report excluded it. Case was handed over to the oncologist for further management.

BACKGROUND
Vaginal cancer is rare, accounting for only about 2% of all cancers of the female reproductive organs, and it is a disease that is rarely encountered in routine clinical practice. Vaginal cancer is mainly treated with radiation therapy or concurrent chemoradiotherapy (CCRT). However, in stage I-II cases, when the lesion is confined to the upper third of the vagina, surgical treatment may include total hysterectomy and vaginal resection with an adequate resection margin. We report a case of stage I vaginal cancer diagnosed at 13 weeks of gestation. There are very few reports on the diagnosis and treatment of vaginal cancer during pregnancy, and it was difficult to decide on a treatment plan; therefore, we report on the course of treatment followed for this patient.
CASE PRESENTATION
The patient was a 38-year-old woman with a history of two pregnancies and zero births. The patient had thrombocytopenia and was diagnosed highly suspicious of myelodysplastic syndrome by bone marrow biopsy, and her platelet count remained at approximately 50,000/μL. At the time of the 11-week gestational checkup, a 4-cm pedunculated tumor was found in the right posterior vaginal fornix. Transvaginal tumor resection was performed at 13 weeks of gestation, and the patient was diagnosed with stage I vaginal cancer (squamous cell carcinoma). Because vaginal cancer was confined to the posterior vaginal wall fornix, radical surgery after abortion was suggested as a treatment plan. However, the patient strongly desired to continue the pregnancy, so the policy was to continue the pregnancy and follow-up. However, at 22 weeks of gestation, a recurrent tumor was found in the posterior fornix of the vagina. The lesion had invaded the paravaginal tissue, making radical surgery impossible. At 26 weeks of gestation, an elective cesarean section was performed because of giving priority to early therapeutic intervention to her recurrent vaginal cancer, and it was decided that CCRT with cisplatin would be administered from postpartum day 1. However, because of thrombocytopenia, chemotherapy could not be co-administered, and the treatment was completed with radiation alone. The therapeutic effect was partial response, but 13 weeks after the end of radiation therapy, we observed regrowth of the recurrent tumor and emergence of pelvic lymph node metastasis. The patient received palliative treatment but died 8 months after delivery due to a generally deteriorating condition, sepsis, and disseminated intravascular coagulation.
CONCLUSIONS
In cases of malignant tumors associated with pregnancy, treatment policies should consider the perinatal prognosis at the same time as treatment for malignant tumors, and gynecologic oncologists, obstetricians, and neonatologists, from the standpoint of their respective specialties, should thoroughly discuss the "curative effect of treatment for malignant tumors" and the "prognosis of the child after birth" and consider the treatment plan for each case.

A 65-year-old woman with suspected ascites-associated abdominal distention had elevated CA125 levels. Contrast-enhanced computed tomography to search for the cause of the ascites showed bilateral pleural effusions, ascites, and an ovarian tumor. On magnetic resonance imaging the tumor exhibited a lobulated structure and markedly low signal intensity on both T1- and T2-weighted imaging, with no restrictions on diffusion-weighted images. Progressive enhancement was observed at tumor margins. Meigs syndrome due to fibroma was suspected, and total hysterectomy, bilateral salpingo-oophorectomy, and partial omentectomy were performed. Postoperatively, the pleural effusion and ascites resolved promptly without specific treatment. On pathological examination, the ovarian tumor was diagnosed as a benign Brenner tumor with scattered nests of transitional epithelium within a large amount of stroma. Based on the clinical course, the patient was diagnosed with pseudo-Meigs' syndrome due to a Brenner tumor.

Review
RATIONALE
PNETs (primitive neuroectodermal tumors) are a family of highly malignant neoplasms characterized by small round cells of neuroepithelial origin. They usually involve bone and soft tissues, and have a higher incidence in childhood.
PATIENT CONCERNS
In this case report, we describe the obstetric and oncological outcome of a huge mass diagnosed as a leiomyoma in a 39-year-old pregnant woman who complained of low back pain, dysuria, and urinary frequency at 22 weeks of gestation.
DIAGNOSES
During the 25th week of pregnancy, the patient was referred to our hospital at night with severe anemia and suspected hemoperitoneum. She underwent an emergency caesarean section, delivering a female fetus weighing 400 g, with an Apgar score of 7 at 1 minute and 9 at 5 minutes.
INTERVENTION
During surgery, we found a huge uterine sarcoma-like metastatic tumor, invading the pelvic peritoneum and parametria bilaterally; the adnexae seemed disease-free. We performed a type B radical hysterectomy, bilateral salpingo-oophorectomy, pelvic peritonectomy, omentectomy, appendectomy, and excision of a bulky lymph node. Seven days after delivery, staging computed tomography (CT) scan demonstrated a large lombo-aortic lymph node compressing the left renal vein and we completed debulking with a second surgery, including diaphragmatic peritonectomy and excision of a huge lymph node by lombo-aortic lymphadenectomy, requiring partial reconstruction of an infiltrated renal vein.
OUTCOME
Ten days after the second surgery, echo-color Doppler showed a regular microcirculation in the left kidney. The patient was discharged after 10 days, and the baby after 1 month, both in good health.Histological examination revealed a uterine body cPNET (central primitive neuroectodermal tumor) orienting the clinical management toward chemotherapy with cisplatin and etoposide.
LESSONS
PNETs are aggressive neoplasms, usually diagnosed at an advanced stage. Due to their low incidence, universally accepted guidelines are still unavailable. Radical surgery leaving no macroscopic residual disease is mandatory in advanced stages. A good fertility-sparing procedure can be performed only in young women at early stages of disease, when the wish for childbearing is not yet fulfilled.

The aim of this study was to present our experience of 18 cases of abdominal radical trachelectomy (ART), including 5 performed during pregnancy, analyzing patient selection, surgical complications, and oncological and obstetrical outcomes. This reproductive study included all early stage cervical cancer patients referred for ART at the 1st Obstetrics and Gynecology Clinic of the Emergency Clinical County Hospital Targu Mures, between 2010 and 2020. A total of 19 women were considered for ART, and only 1 case required conversion to radical hysterectomy. The patient mean age was 31 years (range 24-38 years), and 66.67% of the patients were nulliparous. Six women (33.33%) had stage IA2, 4 (22.22%) had stage IB1, 5 (27.78%) had stage IB2, and 4 (22.22%) had stage IB3 disease. One intraoperative complication occurred in this series, which consisted in both right ureteral and bladder injuries. Early postoperative complications were represented by urinary bladder dysfunction (33.33%), symptomatic pelvic lymphocele (11.1%), peritonitis (5.5%), and wound infection (5.5%). Late postoperative complications included cervical stenosis (5.5%), amenorrhea (11.1%), and pelvic abscess (5.5%). Four out of the 18 patients were operated on during pregnancy between 14 and 20 weeks; 2 of them gave birth at term, 2 of them aborted shortly after the surgery. Two vaginal recurrences were recorded; both were managed by hysterectomy, partial colpectomy and adjuvant chemoradiotherapy. At this moment, all patients are alive with no evidence of disease and 3 of them managed to conceive. In conclusion, ART should be recommended as a fertility-preserving procedure for women in their reproductive age. In selected cases, ART can be performed during pregnancy with encouraging results.

Review
BACKGROUND
Intestinal obstruction caused by endometriosis maybe easily misdiagnosed as a tumor or other occupying disease in emergency condition. How to deal with it depending on the clarity of the preoperative diagnosis and the experience of the surgeon.
CASE PRESENTATION
A 47-year-old woman, admitted to our emergency service with abdominal pain and distension for 5 days, anal stop exhausting and defecating for 3 days. Based on imaging and laboratory examination, we made a preoperative diagnosis of rectal endometriosis probably. After 7 days of colon decompression with a intestinal obstruction catheter, an operation of laparoscopic partial rectal and sigmoid resection without protective stoma and total hysterectomy was performed successfully. The patient obtained a smooth postoperative course and doing well after 12-weeks follow up.
CONCLUSIONS
Obstruction caused by rectal endometriosis is very rare and easily overlooked by surgeon and gynecologist. Appropriate preoperative diagnosis and preoperative management can reduce the trauma and incidence of complications.
