Objective To evaluate the value of gastric contrast-enhanced ultrasound in diagnosing extraluminal duodenal diverticulum. Methods A retrospective analysis was conducted on 40 cases of extraluminal duodenal diverticula confirmed by upper gastrointestinal barium meal and gastroduodenoscopy,all of whom underwent gastric contrast-enhanced ultrasound examination.The detection rate and imaging features of duodenal diverticula were retrospectively analyzed. Results Gastric contrast-enhanced ultrasound detected 34 out of 40 cases of extraluminal duodenal diverticula,with the detection rate (85.0%) higher than that (10.0%,4/40) of conventional fasting ultrasound (P<0.001).Gastric contrast-enhanced ultrasound demonstrated higher detection rate for single diverticula than for multiple diverticula (97.1% vs.44.4%,P<0.001) and was particularly effective for duodenal diverticula in the descending segment (91.7%).According to imaging features,duodenal diverticula were classified into sac-like,gas-containing mass,and air-line types. Conclusion Gastric contrast-enhanced ultrasound facilitates the detection of extraluminal duodenal diverticula in the descending segment,allows concurrent visualization of biliary-pancreatic system pathologies,and enables comprehensive assessment of the association between duodenal diverticula and biliary-pancreatic diseases,demonstrating significant clinical value.

Capsule endoscopy is being increasingly recognized as a gold standard for diagnosing small bowel disease, but along with the increased usage, capsule retention is being reported more frequently. We report a case of capsule endoscopy retention in a diverticulum of the duodenal proximal third portion, which we treated by esophagogastroduodenoscopy. A 69-year-old male visited hospital with hematochezia. He had hypertension and dyslipidemia for several years, and was taking aspirin to prevent heart disease. CT and colonoscopy revealed a diverticulum in the third portion of the duodenum, rectal polyps, and internal hemorrhoids. Capsule endoscopy was performed but capsule impaction occurred. The capsule was later detected by CT in the diverticulum. Endoscopy was performed a day later and the capsule was removed using a net. A small bowel series was conducted after capsule removal, and no stenosis was found. The patient fully recovered and no recurrence of hematochezia was observed at his one month exam. This is the first case in Korea of capsule retention in a duodenal diverticulum, with successful removal by endoscopy.

A 28-year-old Chinese man presented with acute bleeding per rectum. Computed tomography showed a posterior outpouching arising from the distal ileum. The outpouching had hyperaemic walls, but no active contrast extravasation was detected. Technetium-99m pertechnetate scintigraphy showed focal areas of abnormal uptake in the right side of the pelvis, superior and posterior to the urinary bladder. These areas of uptake appeared simultaneously with the gastric uptake and demonstrated gradual increase in intensity on subsequent images. The diagnosis of Meckel's diverticulum was confirmed on surgery and the lesion was resected. The clinical and imaging features of Meckel's diverticulum are discussed.

To evaluate the ultrasound imaging characteristics and diagnostic criteria for acute abdominal Meckel's di- verticulum disease (MD), we retrospectively analyzed the ultrasonic characteristics, clinical data of 58 cases of pathologically proved MD from January 2009 to May 2012. We found that among all the 58 patients, 21 patients were diagnosed with the preoperative clinical diagnosis of MD. Fourteen cases of MD inflammation with acute appendicitis were evaluated by pathological examinations after the surgery. We also found 4 cases of MD with perforation, 15 cases of MD with intussusceptions, 14 cases MD with intestinal obstruction, 5 cases of MD secondary to intestinal obstructionor intestinal necrosis, and 5 cases of MD without any obvious complications. Emergency ultrasound examinations revealed 8 cases of simple MD, 1 case of MD with intussusceptions, 9 cases of MD with acute appendicitis, 12 cases of MD with intestinal obstruction, 2 cases of MD with intussusceptions and intestinal obstruction, 1 case of MD with omphalocele and 1 case of MD with abdominal abscess. The emergency sonographic findings suggested that MD was relatively fixed bowel or thick-walled cystic mass, with one end connected to small intestine, and the other end connected to the blind side, at the periumbilicus region or at the lower right abdomen. A conclusion could be drawn that MD is difficult to be detected by ultrasound (detection rate was about 15. 5%), and MD with complications such as intussusceptions, intestinal obstruction, acute appendicitis can usually be more easily detected (detection rates were 24.1%, 24.1% and 15.5%, respectively). Sonography is a simple, effective way to make diagnosis and differential diagnosis of MD with different acute abdomen symptoms from other disease.

This report highlights the rare occurrence of a huge gangrenous Meckel's diverticulum in an adult, which was managed successfully with laparoscopic resection. A 45-year-old woman presented with a one-day history of right iliac fossa pain with fever and vomiting. Computed tomography showed a huge gangrenous Meckel's diverticulum. The patient underwent laparoscopic exploration and extracorporeal stapled resection of the Meckel's diverticulum. This case serves to highlight the safety and feasibility of performing a laparoscopic resection of a huge gangrenous Meckel's diverticulum in an adult.

Left ventricular diverticulum is a rare congenital anomaly of which the incidence was reported to be 0.26%. Diverticula are usually localized near the apex and most often involve the inferior or anterior parietal walls of the left ventricle. In this report, we describe a rare case of congenital isolated left ventricular apical diverticulum, which was tako-tsubo-like in systole, "dumbbell-like" the whole left ventricle, diagnosed by angiography and magnetic resonance imaging.
