Placenta accreta spectrum (PAS) refers to abnormal trophoblast invasion into the myometrium. The global prevalence of PAS is rising as the number of caesarean deliveries increases. PAS is associated with higher rates of maternal morbidity and mortality. Although mainstream management has been caesarean hysterectomy, uterine conservative techniques are also used, such as the extirpative technique, leaving the placenta in situ, the triple-P procedure, embolisation, uterine balloon tamponade and methotrexate medication. This case report describes an innovative yet simple and safe technique, namely partial myometrial resection of the focal adherent placenta. Unlike hysterectomy, this technique can preserve fertility. It was performed on an undiagnosed focal placental accreta during a caesarean section with a routine caesarean section theatre set-up and did not require obstetric follow-up after the patient was discharged. This procedure can be considered an option for managing focal placenta accreta.

OBJECTIVE
To introduce the application of the perivesical fat rotational flap as a substitute for omental interposition during several complex urologic reconstruction. We highlight our technique using a case of salvage prostatectomy after initial high-intensity focused ultrasound for recurrent high-risk prostate cancer requiring future adjuvant radiation treatment. We have also successfully used this technique in the management of recurrent vesicovaginal, colovesical, rectourethral fistulas, and postradiation salvage prostatectomy setting.
MATERIALS AND METHODS
Our first patient underwent salvage radical prostatectomy after developing high-risk localized prostate cancer after initial high-intensity focused ultrasound. The prostate was radically resected after stepwise posterior and anterior dissections. A flap of perivesical fat with a wide-based pedicle overlying the bladder dome was developed until it was rotated, positioned, and tethered overlying the anterior rectal wall in a tension-free manner. This perivesical fat interposition may have protected a radiated anterior rectal wall from future complications. In the second case, a recurrent vesicovaginal fistula that persisted for 2years postabdominal hysterectomy was repaired using the robotic approach. After fistula excision, layer closure, and perivesical flap interposition, successful repair was achieved. The third patient, who had a history of colon cancer managed with partial colectomy and radiation, developed a recurrent colovesical fistula, which was successfully repaired. Postrepair, a perivesical flap was developed and secured over the site.
RESULTS
In the immediate postoperative follow-up period, there were no surgical complications. Long-term follow-up ranges from 1month to 3years without evidence of complication.
CONCLUSION
In cases where omentum interposition is not feasible, our novel technique of a perivesical fat flap is a successful alternative for complex reconstruction.

BACKGROUND
Angiosarcoma (AS) is a rare and highly aggressive soft tissue disease that most commonly arises in deep soft tissues. There are only a few reported cases of AS involving the ovary and even fewer reports of the underlying molecular abnormalities. Here, we briefly review two cases of primary ovarian AS (oAS) with specific molecular events and immune checkpoints. The clinical features and prognosis of the disease, diagnosis, differential diagnosis, and new treatment approaches are discussed based on a literature review.
CASE SUMMARY
Case 1: A 51-year-old female patient was admitted with right lower limb pain for 5 mo, and lower abdominal pain with hematuria for 1 mo. Partial removal of rectus abdominis muscle and fascia, partial hysterectomy, bilateral salpingo-oophorectomy, and inguinal and pelvic lymphadenectomy were performed. Pathology revealed primary oAS. Fluorescence hybridization revealed gene amplification. MESNA + ADM + IFO + DTIC (MAID) regimen was administered, but stable disease was achieved. The patient died 1 mo later. Case 2: A 41-year-old female patient presented with fatigue, nausea, decreased appetite, and diffuse abdominal pain. On physical examination, the abdomen was distended and a complex cystic mass was palpable in the right pelvic cavity. Pathology revealed primary oAS. MAID chemotherapy was administered and programmed death ligand 1 (PD-L1) staining was performed on the tumor samples. The patient benefited from anti-PD-1 immunotherapy and is alive without any evidence of disease 27 mo off therapy in follow-up.
CONCLUSION
Long-term survival benefit for primary oAS can be achieved by alternative therapeutic strategies using pathological indicators to inform treatment.

BACKGROUND
Flap reconstruction is often required after pelvic tumor resection to reduce wound complications. The use of perforator flaps has been shown to reduce donor site morbidity. The purpose of this study was to evaluate the outcomes of pedicled deep inferior epigastric perforator (pDIEP) flap reconstruction.
METHODS
This was a retrospective multicenter study of patients who underwent immediate pDIEP flap reconstruction for a pelvic or perineal defect after tumor resection between November 2012 and June 2022. The primary outcome was abdominal donor site morbidity, and the secondary outcome was perineal morbidity.
RESULTS
Thirty-four patients (median age, 57.5 years) who underwent pelvic exenteration (n = 31), extralevator abdominoperineal excision (n = 2), or extended vaginal hysterectomy (n = 1) were included. The most common indications were recurrent cervical (n = 19) and anal (n = 4) squamous cell carcinoma. Twenty-nine patients (85%) had a history of radiotherapy. Only one patient (3%) had major (Clavien-Dindo ≥ III) donor site complications (surgical site infection due to tumor recurrence). Eleven patients (32%) had at least one major recipient site complication (surgical site infection [n = 1], total [n = 2] or partial [n = 1] flap loss, perineal dehiscence [n = 2], hematoma [n = 1], fistula [n = 5]). No incisional or perineal hernias were observed during follow-up. Ninety-day survival was 100%.
CONCLUSION
Pedicled DIEP flap reconstructions performed by experienced surgical teams had good outcomes for perineal or vaginal reconstruction, with low abdominal morbidity, in patients with advanced pelvic malignancies who had undergone median laparotomy. The risks and benefits of this procedure should be carefully evaluated preoperatively using clinical and imaging data.

Risk prediction models for cancer stage at diagnosis may identify individuals at higher risk of late-stage cancer diagnoses. Partial proportional odds risk prediction models for cancer stage at diagnosis for males and females were developed using data from Alberta's Tomorrow Project (ATP). Prediction models were validated on the British Columbia Generations Project (BCGP) cohort using discrimination and calibration measures. Among ATP males, older age at diagnosis was associated with an earlier stage at diagnosis, while full- or part-time employment, prostate-specific antigen testing, and former/current smoking were associated with a later stage at diagnosis. Among ATP females, mammogram and sigmoidoscopy or colonoscopy were associated with an earlier stage at diagnosis, while older age at diagnosis, number of pregnancies, and hysterectomy were associated with a later stage at diagnosis. On external validation, discrimination results were poor for both males and females while calibration results indicated that the models did not over- or under-fit to derivation data or over- or under-predict risk. Multiple factors associated with cancer stage at diagnosis were identified among ATP participants. While the prediction model calibration was acceptable, discrimination was poor when applied to BCGP data. Updating our models with additional predictors may help improve predictive performance.

Review
A Cesarean Scar Pregnancy (CSP) is a variant of uterine ectopic pregnancy defined by full or partial implantation of the gestational sac in the scar of a previous cesarean section. The continuous increase of Cesarean Deliveries is causing a parallel increase in CSP and its complications. Considering its high morbidity, the most usual recommendation has been termination of pregnancy in the first trimester; however, several cases progress to viable births. The aim of this systematic review is to evaluate the outcome of CSP managed expectantly and understand whether sonographic signs could correlate to the outcomes. An online-based search of PubMed and Cochrane Library Databases was used to gather studies including women diagnosed with a CSP who were managed expectantly. The description of all cases was analysed by the authors in order to obtain information for each outcome. 47 studies of different types were retrieved, and the gestational outcome was available in 194 patients. Out of these, 39 patients (20,1%) had a miscarriage and 16 (8,3%) suffered foetal death. 50 patients (25,8%) had a term delivery and 81 (41,8%) patients had a preterm birth, out of which 27 (13,9%) delivered before 34 weeks of gestation. In 102 (52,6%) patients, a hysterectomy was performed. Placenta Accreta Spectrum (PAS) was a common disorder among CSP and was linked to a higher rate of complications such as foetal death, preterm birth, hysterectomy, haemorrhagic morbidity and surgical complications. Some of the analysed articles showed that sonographic signs with specific characteristics, such as type II and III CSP classification, Crossover Sign - 1, "In the niche" implantation and lower myometrial thickness could be related to worse outcomes of CSP. This article provides a good understanding of CSP as an entity that, although rare, presents with a high rate of relevant morbidity. It is also understood that pregnancies with confirmed PAS had an even higher rate of morbidity. Some sonographic signs were shown to predict the prognosis of these pregnancies and further investigation is necessary to validate one or more signs so they can be used for a more reliable counselling of women with CSP.

BACKGROUND
Clinically silent uterine rupture with complete fetal expulsion into the abdominal cavity is an extremely rare complication. Diagnosis can be difficult and the risk to the mother and fetus is high. Conservative management has been described only in a few cases of partial expulsion of the fetus so far.
CASE PRESENTATION
We present a case of 43-year-old tercigravida with a history of previous laparotomic myomectomy and subsequent cesarean section. The subsequent pregnancy was complicated by uterine wall loosening and rupture at the site of the previous uterine scar after myomectomy and complete fetal expulsion into the abdominal cavity. The diagnosis was made at 24 + 6 weeks of gestation. Considering the absence of clinical symptomatology and the good condition of the fetus, a conservative approach was chosen with intensive monitoring of the maternal and fetal conditions. The pregnancy ended by elective cesarean section and hysterectomy at 28 + 0 weeks of gestation. The postpartum course was uneventful and the newborn was discharged to home care 63 days after delivery.
CONCLUSIONS
Fetal expulsion into the abdominal cavity after silent uterine rupture of the scarred uterus may be accompanied by minimal symptomatology making early diagnosis difficult. This rare complication must be considered in the differential diagnosis in women after major uterine surgery. In selected cases and under conditions of intensive maternal and fetal monitoring, conservative management may be chosen to reduce the risks associated with prematurity.

OBJECTIVE
Resuscitative endovascular balloon occlusion of the aorta for placenta accreta spectrum is used to control maternal hemorrhage during cesarean hysterectomy. This study aimed to assess the efficacy of resuscitative endovascular balloon occlusion of the aorta for placenta accreta spectrum by examines the change in the quantitative blood loss after applying resuscitative endovascular balloon occlusion of the aorta.
METHODS
This retrospective cohort study included patients with placenta accreta spectrum who required cesarean hysterectomy ( = 37) between 2003 and 2022 at a tertiary care center. Patients were divided into two groups (with resuscitative endovascular balloon occlusion of the aorta, = 13; without resuscitative endovascular balloon occlusion of the aorta, = 24). The quantitative blood loss was compared between the groups. Generalized linear mixed models were used to examine changes in quantitative blood loss during cesarean hysterectomy after resuscitative endovascular balloon occlusion of the aorta was applied. The operating surgeon was set as the random effect.
RESULTS
Operation time did not differ significantly between the groups ( = .09). The quantitative blood loss was significantly higher in patients who did not undergo resuscitative endovascular balloon occlusion of the aorta (2160 g) than in patients who did (1110 g; < .01). Resuscitative endovascular balloon occlusion of the aorta significantly decreased the quantitative blood loss during cesarean hysterectomy (partial regression coefficient, 2312; 95% confidence interval, 49-4577; < .05).
CONCLUSION
Resuscitative endovascular balloon occlusion of the aorta decreased the quantitative blood loss during cesarean hysterectomy in patients with placenta accreta spectrum without significantly increasing the operation time. This suggests that resuscitative endovascular balloon occlusion of the aorta is effective in patients with placenta accreta spectrum.

AIM
Renal leiomyoma is a rare benign mesenchymal tumor arising from the smooth muscle cells of the kidney. Renal capsule is its most common location (1). Large tumor may require surgical excision which can be challenging in case of proximity to major vessels (2). Indications of robotic partial nephrectomy (RPN) have exponentially expanded over the past few years (3). We aim to report a case of large renal leiomyoma successfully managed with RPN.
METHODS
A 59-year-old female patient with BMI 51 presented with chief complaint of abdominal discomfort. The patient underwent a CT scan that revealed a massive circumscribed exophytic complex solid cystic mass of 4.5 x 7.7 x 6.2 cm, arising from the lower pole of right kidney and abutting the inferior vena cava. RENAL score was 11ah (high complexity). Past surgical history included mid-urethral sling, breast reduction, and hysterectomy with salpingectomy. Preoperative creatinine and eGFR were 0.9 (mg/dL) and 77 (mL/min), respectively. A robotic excision of this mass was successfully performed by using Da Vinci Xi platform. Main steps of the procedure are illustrated in the present video.
RESULTS
Dissection and isolation of the tumor were carefully performed after identifying key anatomical structures such as the ureter, the IVC and the renal hilum. Intraoperative ultrasound was used to confirm the margins of the mass. The renal artery was clamped and then the tumor was resected/enucleated. Renal parenchyma was re-approximated with a single layer of interrupted CT-1 Vicryl 0 with sliding clip technique. Warm ischemia time was 19 min. Estimated blood loss (EBL) was 250 ml. Operative time was 165 min. No intraoperative complications occurred. No drain was placed. Patient was discharged on postoperative day 2. Post-operative hypotension was managed with fluid bolus. Postoperative creatinine and eGFR were 1,0 (mg/dL) and 69 (mL/min/1.72m2), respectively. Pathology revealed a leiomyoma of genital stromal origin with hyalinization and calcification.
CONCLUSIONS
To the best of our knowledge, this is the first description of RPN for the management of a large (about 8 cm) renal leiomyoma. Robotic assisted surgery allows to expand the indications of minimally invasive conservative renal surgery whose feasibility becomes even more clinically significant in case of benign masses which can be managed without sacrificing healthy renal parenchyma.
