Ovarian cystadenomas are benign epithelial neoplasms, many of which are of the serous subtype. Most patients present with symptoms such as abdominal pain, bloating, and bladder issues. This patient, who had a BMI of 45, presented with a giant ovarian serous cystadenoma identified during an elective bariatric surgery; interestingly, she was completely asymptomatic at the time of discovery. A large, predominantly cystic pelvic mass with internal septations and soft tissue components, suspicious for ovarian neoplasm, was discovered on a CT abdomen and pelvis with IV contrast. She underwent an exploratory laparotomy with complete resection, right oophorectomy, and ovarian cystectomy. Her postoperative pathology report revealed the mass to be a benign serous cystadenoma. This case serves as an example of how a massive tumor can potentially get overlooked for many years, only to be detected unintentionally in an asymptomatic patient. Healthcare quality is often negatively impacted by the inherent prejudice that many healthcare providers have toward their obese patients. Providers may mistakenly over-attribute a patient's symptoms to their obesity, failing to effectively evaluate the patient's concerns, which could lead to overlooking potentially harmful diagnoses. A comprehensive history and physical exam in all patients, especially those who are obese, is vital in ensuring timely diagnosis and management to improve patient outcomes.

Background Gender dysphoria is treated with gender affirmation surgery (GAS) for assigned male at birth (AMAB) individuals. This study aimed to evaluate the postoperative anatomical changes in AMAB individuals who underwent GAS using magnetic resonance imaging (MRI) and to compare it with cis-females, thereby assessing the efficacy of the surgical technique in achieving pelvic anatomy similar to cis-females. Methodology This was a prospective observational study done in a tertiary care hospital. AMAB individuals who underwent gender affirmation genital surgery using single-stage solely penile skin inversion vaginoplasty were included after informed consent and approval by the Institutional Human Ethics Committee. Patients with complications such as deep space surgical site infection (SSI) and neo-vaginal prolapse were excluded. All the study participants were advised a vaginal self-dilatation regimen, reviewed three months after the surgery, and subjected to an MRI of the pelvis with a vaginal tutor. Parameters such as neo-vaginal depth, alpha (α) angle, rectovaginal thickness, and remnant of corpora cavernosa were measured and compared with cis-female parameters measured from images in the archives from the Department of Radiology. Result A total of 21 patients were included in the study, with a mean age of 27±4.7. Between the study group and cis-females, no significant difference was seen in vaginal depth, and cis-females had significantly higher values in other parameters. There was a significant difference between the subgroups, i.e., defaulters and non-defaulters in soft tissue parameters such as vaginal depth (p=0.001), α angle (p=0.002), and rectovaginal thickness (p=0.002) with the non-defaulter patients having higher values. Conclusion Single-stage penile skin inversion vaginoplasty is capable of producing anatomical parameters, importantly neo-vaginal depth, which is fairly comparable with cis-female, as evident in the non-defaulter subgroup patients. Proper compliance with the vaginal dilatation regimen plays a significant role in the maintenance of soft tissue pelvic anatomical parameters.

BMC Veterinary Research Jun 2024This study aims to describe a rare case of primary ureteral hemangiosarcoma, in which surgical intervention preserved the kidney and ureter after tumor removal.
BACKGROUND
This study aims to describe a rare case of primary ureteral hemangiosarcoma, in which surgical intervention preserved the kidney and ureter after tumor removal.
CASE PRESENTATION
A 13-year-old, neutered male dog, weighing 14 kg, mixed-breed, presented with apathy, anorexia, acute-onset vomiting, and abdominal discomfort during the physical examination. Ultrasonography and pyelography revealed a right-sided dilation of the renal pelvis and ureter due to complete obstruction in the middle third of the ureter. A mass obstructing the lumen of the right ureter was completely resected, and ureteral suturing was performed, preserving the integrity of the involved structures. Histopathology confirmed primary ureteral hemangiosarcoma. Due to the local and non-invasive nature of the mass, chemotherapy was not initiated. The patient's survival was approximately two years, and normal renal function was preserved throughout this period.
CONCLUSIONS
Considering this type of tumor in the differential diagnosis of upper urinary tract obstructive disorders. Furthermore, the preservation of the ureter and kidney is a suitable therapeutic option after surgical resection of non-invasive tumors.

INTRODUCTION
Omental torsion is a rare cause of acute abdominal pain caused by twisting of the omentum along its long axis, thus compromising its vascularity. Its presentation is non-specific and can mimic other common pathologies, making its pre-operative diagnosis challenging.
PRESENTATION OF CASE
A 44-year-old female presented for periumbilical abdominal pain. Her laboratory results showed no leukocytosis and CRP was within normal range. CT scan of the abdomen and pelvis with oral and IV contrast showed a well demarcated pericecal mass at the right side, mostly suggestive of transmesenteric internal herniation with strangulation. The patient eventually required laparoscopic surgical intervention.
DISCUSSION
The acute abdominal manifestations in patients with omental torsion are due to the development of edema and necrotic tissue distal of the torsion after the arterial supply and venous drainage have been obstructed. Rotation around the right gastroepiploic artery is considered to be the most common cause of omental torsion. Primary torsion is considered to be idiopathic, while secondary torsion occurs due to an identifiable predisposing pathology such as omental cysts, hernias, adhesions, or intra-abdominal tumors. Since symptoms of omental torsion are non-specific, it is crucial to consider the differential diagnosis and rule out other causes of acute abdomen. Surgical intervention is the mainstay treatment when there is uncertainty in the diagnosis, or when the patient's clinical, radiological, and laboratory findings worsen with conservative treatment.
CONCLUSION
Early surgical intervention in cases of omental torsion reduces the incidence of formation of abscesses, adhesions, and omental necrosis. In cases of non-operative candidates, conservative treatment is the best option; therefore, the choice of treatment of omental torsion should be considered on a case-by-case basis.

Multi-parametric MRI (mpMRI) studies are widely available in clinical practice for the diagnosis of various diseases. As the volume of mpMRI exams increases yearly, there are concomitant inaccuracies that exist within the DICOM header fields of these exams. This precludes the use of the header information for the arrangement of the different series as part of the radiologist's hanging protocol, and clinician oversight is needed for correction. In this pilot work, we propose an automated framework to classify the type of 8 different series in mpMRI studies. We used 1,363 studies acquired by three Siemens scanners to train a DenseNet-121 model with 5-fold cross-validation. Then, we evaluated the performance of the DenseNet-121 ensemble on a held-out test set of 313 mpMRI studies. Our method achieved an average precision of 96.6%, sensitivity of 96.6%, specificity of 99.6%, and F1 score of 96.6% for the MRI series classification task. To the best of our knowledge, we are the first to develop a method to classify the series type in mpMRI studies acquired at the level of the chest, abdomen, and pelvis. Our method has the capability for robust automation of hanging protocols in modern radiology practice.

PURPOSE
To explore the value of 3D amide proton transfer weighted imaging (APTWI) in the differential diagnosis between benign and malignant bone tumors, and to compare the diagnostic performance of APTWI with traditional diffusion-weighted imaging (DWI).
MATERIALS AND METHODS
Patients with bone tumors located in the pelvis or lower limbs confirmed by puncture or surgical pathology were collected from January 2021 to July 2023 in the First Affiliated Hospital of Zhengzhou University. All patients underwent APTWI and DWI examinations. The magnetization transfer ratio with asymmetric analysis at the frequency offset of 3.5 ppm [MTRasym(3.5 ppm)] derived by APTWI and the apparent diffusion coefficient (ADC) derived by DWI for the tumors were measured. The Kolmogorou-Smirnou and Levene normality test was used to confirm the normal distribution of imaging parameters; and the independent sample t test was used to compare the differences in MTRasym(3.5 ppm) and ADC between benign and malignant bone tumors. In addition, the receiver operating characteristic (ROC) curve was used to evaluate the diagnostic performance of different imaging parameters in differentiation between benign and malignant bone tumors. P<0.05 means statistically significant.
RESULTS
Among 85 bone tumor patients, 33 were benign and 52 were malignant. The MTRasym(3.5 ppm) values of malignant bone tumors were significantly higher than those of benign tumors, while the ADC values were significantly lower in benign tumors. ROC analysis shows that MTRasym(3.5 ppm) and ADC values perform well in the differential diagnosis of benign and malignant bone tumors, with the area under the ROC curve (AUC) of 0.798 and 0.780, respectively. Combination of MTRasym(3.5 ppm) and ADC values can further improve the diagnostic performance with the AUC of 0.849 (sensitivity = 84.9% and specificity = 73.1%).
CONCLUSION
MTRasym(3.5 ppm) of malignant bone tumors was significantly higher than that of benign bone tumors, reflecting the abnormal increase of protein synthesis in malignant tumors. APTWI combined with DWI can achieve a high diagnostic efficacy in differentiation between benign and malignant bone tumors.

Reno alimentary fistula, a rare illness characterized by improper connection between the kidney and digestive tract, can lead to urinary tract infections, abscesses, and severe sepsis. It can also be caused by various factors such as chronic infections, malignancy, cryoablation, or abdominal surgical procedures. We present a case of a 60-year-old man with bilateral staghorn stones who was diagnosed with reno-duodenal fistula and underwent a right simple nephrectomy and fistula closure. The histopathology revealed a well-differentiated squamous cell carcinoma that originated from the renal pelvis.

BACKGROUND
Pelvic Floor Rehabilitation (PFR) is effective in a selection of patients with low anterior resection syndrome (LARS) after rectal cancer surgery. This study aimed to identify barriers and enablers to prepare for successful implementation into clinical practice.
METHODS
A qualitative study was performed, guided by the Consolidated Framework for Implementation Research (CFIR). Individual interviews (n = 27) and two focus groups were conducted to synthesize the perspectives of rectal cancer patients, pelvic floor (PF) physiotherapists, and medical experts.
RESULTS
Barriers were found to be the absence of guidelines about LARS treatment, underdeveloped network care, suboptimal patient information, and expectation management upfront to PFR. Financial status is frequently a barrier because insurance companies do not always reimburse PFR. Enablers were the current level of evidence for PFR, the positive relationship between patients and PF physiotherapists, and the level of self-motivation by patients.
CONCLUSION
The factors identified in our study play a crucial role in ensuring a successful implementation of PFR after rectal cancer surgery.

BACKGROUND
While diverticular disease is prevalent in the West, the formation of giant colonic diverticula is rare. To date, approximately 200 cases have been reported, with only a handful treated surgically using a minimally invasive approach. Furthermore, the natural history of giant colonic diverticula is not well documented.
CASE SUMMARY
This report describes the case of a 66-year-old man who developed a giant colonic diverticulum with primary symptoms including dull and chronic pain in the right lower quadrant at presentation. The patient had undergone several computed tomography scans of the abdomen and pelvis over the previous two years, through which the natural history of this rare entity could be retrospectively observed. The patient was successfully treated with a robot-assisted sigmoid colectomy and had an uneventful recovery with resolution of symptoms during the follow-up.
CONCLUSION
This rare case demonstrates the natural history of giant colonic diverticulum formation and supports the feasibility of robot-assisted surgery.

Exosomes derived from bone marrow-derived mesenchymal stem cells (BMSCs) can alleviate the symptoms of pelvic floor dysfunction (PFD) in rats. However, the potential therapeutical effects of exosomes derived from BMSCs treated with tumour necrosis factor (TNF)-α on the symptoms of PFD in rats are unknown. Exosomes extracted from BMSCs treated with or without TNF-α were applied to treat PFD rats. Our findings revealed a significant elevation in interleukin (IL)-6 and TNF-α, and matrix metalloproteinase-2 (MMP2) levels in the vaginal wall tissues of patients with pelvic organ prolapse (POP) compared with the control group. Daily administration of exosomes derived from BMSCs, treated either with or without TNF-α (referred to as Exo and TNF-Exo), resulted in increased void volume and bladder void pressure, along with reduced peak bladder pressure and leak point pressure in PFD rats. Notably, TNF-Exo treatment demonstrated superior efficacy in restoring void volume, bladder void pressure and the mentioned parameters compared with Exo treatment. Importantly, TNF-Exo exhibited greater potency than Exo in restoring the levels of multiple proteins (Elastin, Collagen I, Collagen III, IL-6, TNF-α and MMP2) in the anterior vaginal walls of PFD rats. The application of exosomes derived from TNF-α-treated BMSCs holds promise as a novel therapeutic approach for treating PFD.
