BACKGROUND
Endometrial adenosarcoma is an unusual type of uterine tumor that features a seemingly benign epithelial component, paired with a low-grade sarcomatous component, usually similar in appearance to endometrial stromal sarcoma. To our knowledge, no image of endometrial adenocarcinoma in the cesarean scar diverticulum has been reported previously.
CASE DESCRIPTION
We present a rare case of endometrial adenocarcinoma located in the cesarean scar diverticulum of a 44-year-old patient. The patient was admitted to our hospital complaining of irregular vaginal bleeding that had lasted for over two months. Both B-ultrasound and magnetic resonance imaging confirmed a mass at the junction of the corpus uteri and cervix. After the initial curettage failed to confirm the disease, a hysteroscopy was subsequently performed. Upon further pathological analysis, a diagnosis of endometrial adenosarcoma was confirmed. The patient underwent hysterectomy and salpingo-oophorectomy. The patient was discharged home four days after the surgery and remained recurrence-free for one year after follow-up.
CONCLUSIONS
Hysteroscopy can serve as a valuable diagnostic tool to identify the lesion in this unique scenario, particularly when curettage fails to diagnose this uncommon condition. We hope that this case would bring awareness of this potential scenario, enabling clinicians in the future to identify similar cases more readily.

INTRODUCTION
Fewer than 200 cases of Perforated Duodenal Diverticulum ("PDD") have been reported in the literature. The percentage of caused by trauma is generally very low and similar to rates recorded for duodenal injuries caused by trauma in the absence of diverticula (3 %-5 %). As a rare cause of abdominal pain after trauma, perforated duodenal diverticula are seldom diagnosed preoperatively. Despite preoperative CT scan demonstrating duodenal perforation, a diverticular origin is often only identified intraoperatively.
PRESENTATION OF CASE
A 36-year-old man was admitted to the emergency department with severe upper abdominal pain that began after blunt trauma by a kick to his upper abdomen during a fight. A duodenal injury was identified by CT. Exploratory laparotomy then revealed a retroperitoneal perforation of a diverticulum located at the second segment of the duodenum.
DISCUSSION
A review of the literature found few cases reporting perforated duodenal diverticulum secondary to trauma. Most cases identified the diverticulum at intraoperative exploration, with most approaches being through open surgery.
CONCLUSION
Perforation of a duodenal diverticulum secondary to trauma is an extremely rare event, which is why it is often overlooked in the differential diagnosis of acute abdomen. As the presenting signs are often suggestive of duodenal perforation without a clear notion of duodenal diverticula at CT scan, a surgical approach and exploration is most frequently described. In our experience, the management of traumatic PDD aligns with the literature favoring the open surgical approach.

Review
OBJECTIVE
To evaluate via a review of published literature, the efficacy of endoluminal ultrasound (ELUS) and optical coherence tomography (OCT) in the following ureteric diseases: urolithiasis, upper tract urothelial carcinoma, stricture disease and pelvic-ureteric junction obstruction (PUJO).
PATIENTS AND METHODS
Ureteric high-frequency ELUS provides 360° imaging, to a depth of 20 mm, and has been demonstrated to assess ureteric stricture length, degree of fibrosis and aetiology. OCT produces high-quality images with a penetration depth of 2 mm. ELUS has proven to be useful at the time of endopyelotomy for PUJO as it can identify crossing vessels, some not detectable on CT angiography, allowing the urologist to avoid these when making their incision. Ureteric ELUS may be utilised for submucosal ureteric stones as they are highly visible. Endoluminal ultrasound may be deployed in the case of known sub-mucosal urolithiasis when the ureter appears stone-free. It may help identify sub-mucosal stones or stones within diverticulum.
RESULTS
Endoluminal ultrasound has been analysed for its use in determining muscle-invasive urothelial carcinoma of the ureter. The PPV for ≥pT2 was only 16.7% in one study of six patients with MIBC and 76.2% in 21 patients with
CONCLUSIONS
Ureteric ELUS has been reported to be a useful tool in endopyelotomy, urolithiasis and stricture disease. The staging of ureteric urothelial carcinoma remains unsatisfactory with current imaging techniques and biopsy methods, and, based on the current literature, ELUS does not appear to have a strong enough PPV to determine muscle invasion. Ureteric OCT may be a useful tool in the future staging of upper tract urothelial carcinoma, particularly in differentiating the stage of small tumours. Further studies are needed in this area.

Esophageal diverticulum is a rare condition characterized by the herniation of the esophageal mucosa outside the esophageal wall. Here, we explore the prevalence of ED and its associated esophageal dysmotility. We also shed light on the potential impact of previous surgical interventions, such as Nissen's fundoplication, on the development of ED. This manuscript presents the case of a 72-year-old woman with a history of Nissen's fundoplication surgery who experienced worsening symptoms of dysphagia, heartburn and postprandial cough. Despite exhibiting a normal motility pattern, upper endoscopy revealed a large epiphrenic esophageal diverticulum. The patient underwent successful surgical resection with myotomy, resulting in the resolution of symptoms with no complications. This case highlights the rarity of symptomatic ED and the need to recognize it while choosing the optimal treatment modality.

The subpectoral diverticulum (SPD) is an extension of the respiratory system in birds that is located between the primary muscles responsible for flapping the wing. Here we survey the pulmonary apparatus in 68 avian species, and show that the SPD was present in virtually all of the soaring taxa investigated but absent in non-soarers. We find that this structure evolved independently with soaring flight at least seven times, which indicates that the diverticulum might have a functional and adaptive relationship with this flight style. Using the soaring hawks Buteo jamaicensis and Buteo swainsoni as models, we show that the SPD is not integral for ventilation, that an inflated SPD can increase the moment arm of cranial parts of the pectoralis, and that pectoralis muscle fascicles are significantly shorter in soaring hawks than in non-soaring birds. This coupling of an SPD-mediated increase in pectoralis leverage with force-specialized muscle architecture produces a pneumatic system that is adapted for the isometric contractile conditions expected in soaring flight. The discovery of a mechanical role for the respiratory system in avian locomotion underscores the functional complexity and heterogeneity of this organ system, and suggests that pulmonary diverticula are likely to have other undiscovered secondary functions. These data provide a mechanistic explanation for the repeated appearance of the SPD in soaring lineages and show that the respiratory system can be co-opted to provide biomechanical solutions to the challenges of flight and thereby influence the evolution of avian volancy.

Background The term "diverticula" refers to the existence of diverticula in the gastrointestinal tract but is mainly located in the sigmoid colon and is used to describe colonic diverticulosis. Diverticula, which are sac-like protrusions in the wall of the large bowel, are becoming more prevalent globally, in both developed and developing nations. This increase in occurrence is primarily attributed to changes in dietary and lifestyle patterns. Raising public awareness can potentially contribute to a decrease in the incidence of the disease and its associated complications. Aim This study aims to assess knowledge and awareness levels among the Saudi Arabian population regarding diverticulitis and its risk factors. Methods A descriptive cross-sectional study was conducted in Saudi Arabia between 1st January 2024 to 1st April 2024 using an online questionnaire for data collection. The target population consists of individuals who are between 18 years and 45, in Saudi Arabia without a history of diverticulitis. The study questionnaire covered participants' demographic (Western, Central, Southern, Eastern, Northern) regions, knowledge, awareness and practice of diverticulitis. Results A total of 548 eligible participants completed the study questionnaire, most of them (80.3%; 395) were from the Western region including Mecca, Medina and Jeddah. Participants' ages ranged from 18 to more than 40 years with a mean age of 30.5 ± 11.9 years old. A greater percentage (72.3%) of the participants were males compared to the percentage of females, which was 27.7%. The vast majority of the study participants had an inadequate knowledge level about diverticulitis (85.9%; 471) while only 31 (5.7%) had adequate knowledge and awareness about the disease. The most reported sources of information included study courses (6.4%), media (5.3%), and physicians (4.7%) while most respondents (83.6%) had no source. Conclusion In conclusion, aside from preventive strategies, the current study found that the public knew very little about diverticulitis, including its risk factors, clinical presentation, and diagnostic process. The two significant predictors of public awareness level were age and doctors as information sources.

PURPOSE
Various complications following hypospadias surgery present distinct manifestations when examined with ultrasound. Utilizing high-frequency ultrasound, clinicians can promptly identify these complications and initiate appropriate treatment. The aim of this study is to catalogue the ultrasonographic presentations of various postoperative complications following hypospadias surgery, thereby providing a reference for ultrasonographic diagnosis.
METHODS
Ultrasonic images of post-hypospadias surgery from October 1, 2015, to June 30, 2023, recorded at the Plastic Surgery Hospital of the Chinese Academy of Medical Sciences, serve as the basis for this investigation. Drawing on patient clinical diagnoses, this study compiles and selects representative ultrasound images of diverse complications.
RESULTS
The study encompassed a total of 121 subjects; 26 demonstrated urethral stricture on ultrasonic images, two presented local urethral dilation, six showed intraurethral hair-like structures, 17 revealed intraurethral septum, two exhibited intraurethral fold, one had urethral calculus, one displayed urethral calcification, 12 indicated intraurethral urine accumulation, and two showed urethral diverticulum.
CONCLUSION
Ultrasound examination is helpful for postoperative diagnosis following hypospadias, detecting complications such as urethral stricture, urethral hair growth, and urethral diverticulum, which can help doctors choose appropriate clinical treatment strategies.

Review
Superior mesenteric artery syndrome (SMAS) is a rare cause of duodenal obstruction which is characterized by compression of the duodenum due to narrowing of the space between the superior mesenteric artery and aorta. Incomplete duodenal obstruction due to SMAS in neonates is rarely reported in the literature. In this case, it is a full-term 2-day-old male with the complaint of recurrent vomiting starting soon after birth. The patient was diagnosed with SMAS and duodenoduodenostomy was performed. Accompanying Meckel's diverticulum was excised.
