OBJECTIVE: Missing occult para-aortic lymph node metastasis is one of the primary concerns of sentinel lymph node biopsy in endometrial cancer. Our study aimed to evaluate the relationship between intrauterine cancer site and isolated para-aortic lymph node metastasis to tailor treatment and reduce the false negative rate of the sentinel lymph node procedure.
METHODS: A retrospective, multicenter, case control study was performed in four international centers. All patients with positive lymph nodes who had complete surgical staging with pelvic and para-aortic lymphadenectomy, between January 2013 and December 2023, were included. Detailed descriptions of the cancer location within the uterine cavity on the cranio-caudal plane and the myometrial wall involvement on the cranio-caudal and ventro-dorsal planes were collected, as were clinical data and cancer histological features. Patients with isolated para-aortic lymph node metastasis were allocated to group 1; patients with pelvic lymph node metastasis and those with both pelvic and para-aortic lymph node metastasis were allocated to group 2. The groups were compared according to the variables collected.
RESULTS: 200 preoperative early stage endometrial cancer patients with postoperative International Federation of Gynecology and Obstetrics 2009/2023 stage IIIC1/IIIC2 were included in our study: 42 patients (21%) with isolated para-aortic lymph node metastasis were allocated to group 1 and the remaining patients to group 2. The two groups had comparable clinical and pathological characteristics (p>0.05): mean age was 66.5±10.3 (group 1) and 63.5±11.9 (group 2); endometrioid histotype was the predominant one for both groups (50%); most patients had myometrial infiltration >50% (80.9% and 79.7%), grade 3 (61.9% and 63.9%), and lymph vascular space invasion (78.5% and 82.2%). Cancers involving the fundal uterine cavity, the fundal myometrial wall, or the anterior myometrial wall were 3.11 (1.04-9.27), 3.03 (1.12-8.21), and 2.12 (0.77-5.80) times more likely to metastasize only to para-aortic lymph nodes compared with cancers located in other uterine sites.
CONCLUSIONS: In this study, the intrauterine location of the cancer determined the site of lymph node metastasis. When the tumor involved the fundus (cavity or wall) and infiltrated exclusively the anterior wall, the baseline risk of spreading only into the para-aortic area increased significantly in selected patients at risk of nodal disease.

Haemangioma of the ribs is considered an extremely rare benign tumour. Here, we present a case of a young male with left tenth rib haemangioma vascularised by a costal artery giving the artery of Adamkiewicz presented as chronic cough. This was successfully treated through preoperative embolisation and surgical resection. A preoperative angiogram was performed to identify the origin of the artery of Adamkiewicz. The final diagnosis was confirmed histopathologically. There were no complications in the postoperative course and no recurrence during 12 months of follow-up.

OBJECTIVE: To evaluate the impact of adjuvant chemotherapy, type of ovarian surgery, and the surgical approach on fertility in patients with stage I immature teratoma of the ovary.
METHODS: Clinicopathologic data were retrospectively collected and analyzed from a cohort of 47 patients with childbearing desire treated for a stage I immature teratoma of the ovary at IRCCS San Gerardo dei Tintori Hospital, Monza, Italy. Multivariate logistic regression was used to address the influence of chemotherapy and type of surgery on the outcome.
RESULTS: Among the patients included, 78.7% (37/47) were able to get pregnant, with a live birth rate of 80.9% (51/63 pregnancies). These rates were not different between adjuvant chemotherapy versus surveillance group (62.5% (5/8) and 82.0% (32/39), respectively; p=0.22) nor between the type of ovarian surgery (cystectomy vs unilateral salpingo-oophorectomy; p=0.57) and surgical approach (laparotomy or laparoscopy; p=0.18). A statistically significant difference was found for stage of disease (a decrease in pregnancy rate from 86.5% (32/37) for stage IA to 50.0% for stage IC (5/10); p=0.02), but it was not confirmed in the multivariate analysis. After relapse diagnosis and management, a total of 62.5% (5/8) of patients conceived and had at least one live birth baby.
CONCLUSIONS: The fertility-sparing approach is feasible in this population, and fertility does not depend on surgical approach or post-operative treatment. However, adjuvant chemotherapy should be carefully evaluated in this setting.

Peritoneal involvement represents one of the major difficulties that arise during the treatment of pancreatic adenocarcinoma. In fact, currently, there is a growing interest in the administration of intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC) as an adjunct to surgical pancreatic resection, both with prophylactic or therapeutic intent. With this video, we report a case of pancreatic body adenocarcinoma treated with fully laparoscopic distal splenic pancreatectomy with intraoperative HIPEC with gemcitabine, administered initially with a prophylactic intent, based on a preliminary negative peritoneal washing cytology result. In our case, the association of HIPEC and surgical resection did not affect the postoperative recovery, and after 15 months of follow-up, the patient remains alive and has no signs of disease recurrence.

OBJECTIVE: To investigate preoperative MRI evaluation of the features of the mylohyoid muscle (MM) predictive of its infiltration in oral squamous cell carcinoma (OSCC) treatment planning, defining the most appropriate sequences to study its deep extension into the floor of the mouth (FOM).
METHODS: We applied a 7-point score to retrospectively evaluate preoperative imaging of patients who underwent surgery for OSCC over 11 years. The results were compared with histopathological findings using Spearman\'s rank coefficient. Receiver operating characteristic curves were employed to assess the score\'s ability to predict MM infiltration, determining optimal thresholds for sensitivity, specificity, and predictive values. The Mann-Whitney U-test confirmed that infiltration judgments did not overlap around this threshold. Cohen\'s K statistical coefficient was used to evaluate the interobserver agreement.
RESULTS: Fifty-two patients (mean age 66.4 ± 11.9 years, 36 men) were evaluated. Histopathological examination found MM infiltration in 21% of cases (n = 11), with 90% classified in the highest Score categories. A score > 4 proved to be the best cut-off for predicting the risk of MM infiltration, with a sensitivity of 91% (CI: 0.57-0.99), specificity 61% (CI: 0.45-0.76), PPV 38% (CI: 0.21-0.59), and NPV 96% (CI: 0.78-0.99). At the subsequent single-sequence assessment, the TSE-T2wi had the highest diagnostic accuracy, with sensitivity 90% (CI: 0.57-0.99), specificity 70% (CI: 0.53-0.82), PPV 45% (CI: 0.25-0.67), and NPV 96% (CI: 0.80-0.99).
CONCLUSIONS: The 7-point score is a promising predictor of safe surgical margins for MM in OSCC treatment, with the particular benefit of T2-weighted sequences.
CONCLUSIONS: Our scoring system for tumor infiltration of MM, which is easy to use even for less experienced radiologists, allows for uniformity in radiological language, thereby ensuring crucial preoperative information for the surgeon.
CONCLUSIONS: The relationship of the MM to an oral lesion may impact surgical planning. As the score increases, there is a greater incidence of infiltration in the MM. Our score system improves radiologists\' reporting for MM involvement by tumor.

Intraoperative ultrasound is described widely in multiple pathological scenarios in adult practice and in image-guided interventions in children. We aim to describe the technique and range of potential uses of intraoperative ultrasound in paediatric urological surgery, from outlining the process of case selection, preparation, and logistics to demonstrating the ranging benefits of real-time, high spatial resolution ultrasound during resection. At our centre, we use intraoperative ultrasound to assist in a variety of operations. These include guiding excision margins in nephron-sparing surgery, assessing for vascular infiltration in renal tumours, and identifying salvageable testicular tissue in orchidectomy. By exhibiting these scenarios, we hope to display the unique value that intraoperative ultrasound can have to the paediatric surgeon and inspire additional uses further afield.

We present a case of haemobilia as a primary presentation for underlying cholangiocarcinoma. A man in his 50s initially presented to emergency with Quincke\'s triad, RUQ pain, jaundice and UGI bleeding. The initial diagnosis of haemobilia was made on endoscopic retrograde cholangiopancreatography (ERCP) on primary presentation, but the presence of blood and the recurrent clot obstruction of the biliary tract made the underlying diagnosis extremely difficult, resulting in the patient having 4 ERCP, 1 spyglass and multiple CTs and magnetic resonance cholangiopancreatography. Eventually, the patient underwent a Whipple\'s procedure without tissue diagnosis, confirming cholangiocarcinoma on histopathology. This case emphasises the difficulty of diagnosis of underlying malignancy in the setting of haemobilia, the benefit of multidisciplinary meeting discussions to support significant interventions and the need to be cautious and curious when managing atypical presentations.
