Chilaiditi syndrome is an extremity rare disease that is typically asymptomatic, but can lead to fatal complications, such as volvulus, perforation, and bowel obstruction. This paper reports a case of an 80-year-old female patient who was admitted for right upper quadrant pain and nausea. She showed a positive Murphy sign with tenderness in the right upper quadrant area. Abdominal ultrasound showed that the gall bladder was normal, but abdominal computed tomography revealed multiple small bowel loops interposed among the liver and diaphragm, as well as an abrupt small transition in the bowel caliber with air fluid levels. Therefore, she was diagnosed with an acute small bowel obstruction by Chilaiditi syndrome. She was managed with surgical repair and was discharged without complications after 18 days of admission. Small bowel obstructions by Chilaiditi syndrome is one etiology of which every emergency physician should be aware.

Follicular lymphoma is the most common form of low-grade B cell lymphoma. Follicular lymphoma occurs predominantly at lymph node sites and rarely in the gastrointestinal tract. Rare gastrointestinal follicular lymphoma is most commonly found in the small intestine, especially in the duodenum, and appears as multiple granules. However, gastric follicular lymphoma mostly appears as a subepithelial tumor. We observed two primary gastric follicular lymphomas that resembled subepithelial tumors located in the body of the stomach. Endoscopic ultrasound revealed hypoechoic lesions located in the submucosa layer. Since endoscopic forceps biopsies were inconclusive, we performed endoscopic submucosal dissection, which resulted in a final pathologic diagnosis of follicular lymphoma. Because of the indolent nature of gastrointestinal follicular lymphoma, the “watch and wait” strategy can be applied in the early phase. The identification of endoscopic characteristics of gastric follicular lymphoma can be helpful for differential diagnosis and decision of treatment strategy. Therefore, we report two cases of primary gastrointestinal follicular lymphoma diagnosed following endoscopic submucosal dissection.

PURPOSE: Intussusception is a common cause of intestinal obstruction in children. While most patients can be treated by enema reduction, about 20% require surgery. We investigated the usefulness and feasibility of laparoscopic surgery and the intraoperative risk of bowel resection. METHODS: We retrospectively reviewed pediatric patients who underwent surgery for intussusception from 2010 to 2017. We collected data for age, gender, body weight, associated symptoms, duration of symptoms, white blood cell count, operating time, and postoperative complications. RESULTS: Of 155 patients, 37 (23.8%) underwent surgery due to enema reduction failure in 29 (78.3%), recurrence in 6 (16.3%), a suspicious lead point in 1, and suspicious ischemic change observed on ultrasonography in 1. The mean age was 26.8±18.9 months (range, 3.5~76.7 months), and the mean body weight was 12.9±3.9 kg (range, 5.4~22.2 kg). Laparoscopic surgery was successful in 29 patients (78.4%), and 7 (18.9%) needed bowel resection and anastomosis. The mean operating time was 56.7±32.8 min. A lead point was found in 3 patients in the bowel resection group (p=0.005); in addition, the operating time and hospital stay were longer in this group. There were no intra- or postoperative complications. CONCLUSION: Laparoscopic surgery was successful in 78.4% of the patients with a short hospital stay and early oral intake. The only predictive factor for bowel resection was the presence of a lead point. Laparoscopic surgery may be an optimal treatment intervention for children with intussusception, except for those who show initial peritonitis.

Polypoid or tumorous arteriovenous malformation (AVM) of small intestine is rare and can be misdiagnosed as other tumorous conditions. We experienced a rare case of giant jejunal AVM in a 15-year-old boy, who complained of intense abdominal pain. Ultrasonography and contrast-enhanced CT revealed a 13.5-cm-sized multiseptated cystic mass arising in small intestine, which was mimicking submucosal tumor. It was successfully treated by surgical resection. The specimen showed a multilobulated outbulging submucosal mass in jejunum. Histopathologic evalulation confirmed AVM located in the submucosa, muscularis propria and subserosa. This case is the largest AVM of small intestine among which has ever been reported.

BACKGROUND/AIMS: The incidence of adult small bowel intussusception detected at CT has increased with advanced imaging techniques and universal utilization of CT scan. We aimed to identify factors that could predict the necessity of surgical intervention in adult patients with small bowel intussusception detected at CT during the past decade. METHODS: There were 39 cases of adult small-bowel intussusception detected at CT from January 2004 to June 2014. The data on clinical factors, radiological factors and outcomes were collected by retrospectively reviewing all available medical records. Patients were classified as surgical group and conservative group according to the outcome. Association between predictive factors and outcome was assessed by Fisher's exact test and logistic regression models. RESULTS: Among a total of 39 patients, there were 32 patients (82%) in the conservative group and 7 patients (18%) in the surgical group. Spontaneous reduction was confirmed at short-term follow-up studies (abdominal ultrasonography [n=14], single contrast small bowel series [n=14], CT [n=4]) in the conservative group. No recurrence occurred during the median follow-up period of 14.1 months (range, 0-67.5 months). Patients in the surgical group had significantly higher white blood cell (WBC) counts (OR 1.001, p=0.048), more frequent obstruction (n=4 vs. n=4, p=0.022) or leading point (n=5 vs. n=0, p<0.001) and longer intussuception length (OR 1.929, p=0.032). CONCLUSIONS: Factors associated with the necessity to resort to surgical intervention in adults with small bowel intussusceptions were higher WBC counts, presence of obstruction or leading point, and longer intussuception length. Conservative management can be considered with short-term follow-up for those without these predictive factors.

PURPOSE: To evaluate ultrasonographic accuracy in the differentiation of a bezoar from feces in a small bowel obstruction showing feces-like material just proximal to the transitional zone in abdominal computed tomography (CT). METHODS: This study included 14 patients who showed feces-like material just proximal to the transitional zone, among 302 patients diagnosed with small bowel obstruction on abdominal CT. The diagnostic signs of a bezoar on ultrasonography included an arc-like surfaced intraluminal mass, posterior acoustic shadow and twinkling artifacts. The diagnostic performance of ultrasonography in each patient was compared with a final diagnosis that was surgically or clinically made. RESULTS: Among the 14 patients, seven were ultrasonographically diagnosed as having a bezoar, and five of the seven were surgically diagnosed as having a phytobezoar. The remaining two of the seven showed complete symptomatic improvement before surgery. The other seven patients were ultrasonographically diagnosed as not having a bezoar. Among them, six patients were conservatively treated with symptomatic improvement, suggesting the absence of a bezoar. The remaining one patient was confirmed not to have a bezoar during adhesiolysis. In all patients, the ultrasonographic diagnosis agreed with the clinically confirmed diagnosis. CONCLUSION: Ultrasonography might be an accurate method for the differential diagnosis of feces-like material just proximal to the transitional zone in abdominal CT. It can help radiologists to quickly and easily diagnose a bezoar.

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.

OBJECTIVETo study the ultrasonographic and morphologic features of intestinal lymphoma.

METHODSThe ultrasonographic and morphologic features of 19 patients with intestinal lymphoma were retrospectively analyzed. RESULTS All the patients were confirmed as non-Hodgkin's lymphoma by endoscopy or pathology. Of these 19 cases,the involved locations included ileum(n=14),duodenum(n=3),and ileocecum(n=2). The main sonographic types included mass type(n=12),bowel wall thickening type(n=1),and nonspecific signs(n=6). The mass type was characterized by solid and cystic-solid hypoechoic(including marked hypoechoic)foci,with well-defined margin,and rich blood signals were visible in large masses. The bowel wall thickening type was characterized by the thicking of bowel walls,showing hypoechoic(including marked hypoechoic),along with posterior acoustic enhancement. The nonspecific signs included e.g. dilatation of intestine and mesenteric lymph node enlargement. Morphologically,the tumor was featured by intestinal mass in intestinal mucosa or the circumferential thickening of intestinal wall.

CONCLUSIONSmall intestinal lymphoma has typical ultrasonographic features,and ultrasonography can provide useful information in the diagnosis of small intestinal lymphoma.

Femoral hernias account for up to 4% of all hernias that occur in the inguinal region. The hernial sac usually contains the greater omentum, small intestine, large intestine and preperitoneal fat, but rarely, in only 0.8% of the all cases, it also contains the appendix. Femoral, inguinal and incisional hernias, combined with appendicitis, occur in only 0.13% of cases. Thus, the incidence of appendicitis associated with a femoral hernia would be expected to be very rare. Herein, a case of an incarcerated femoral hernia, including a gangrenous appendix, is reported. An 81-year-old female was admitted with a protruding mass in the right inguinal area of 2 days duration. On inspection, a 4x3 cm sized erythematous bulging mass was noted. On palpation, the mass was tender and fixed in nature. There were no signs of peritoneal irritation or other palpable masses in the whole abdomen. Under the impression of a femoral hernia, a manual reduction was attempted, but to no avail. An immotile edematous intestine was noted on ultrasonography, and fluid retention with decreased blood circulation was noted in the intestine, suggestive of incarceration. An emergency operation was performed, with an incision made through the right groin region, where an incarcerated femoral hernia, including a gangrenous appendix, was found. An appendectomy and McVay repair were performed. The patient was discharged after 5 days, without any complications.

OBJECTIVE: To describe the sonographic (US) and clinical features of spontaneously reduced small bowel intussusception, and to discuss the management options for small bowel intussusception based on US findings with clinical correlation. MATERIALS AND METHODS: During a five years of period, 34 small bowel intussusceptions were diagnosed on US in 32 infants and children. The clinical presentations and imaging findings of the patients were reviewed. RESULTS: The clinical presentations included abdominal pain or irritability (n = 25), vomiting (n = 5), diarrhea (n = 3), bloody stool (n = 1), and abdominal distension (n = 1), in combination or alone. US showed multi-layered round masses of small (mean, 1.5+/-0.3 cm) diameters and with thin (mean, 3.5+/-1 mm) outer rims along the course of the small bowel. The mean length was 1.8+/-0.5 cm and peristalsis was seen on the video records. There were no visible lead points. The vascular flow signal appeared on color Doppler images in all 21 patients examined. Spontaneous reduction was confirmed by combinations of US (n = 28), small bowel series (n = 6), CT scan (n = 3), and surgical exploration (n = 2). All patients discharged with improved condition. CONCLUSION: Typical US findings of the transient small bowel intussusception included 1) small size without wall swelling, 2) short segment, 3) preserved wall motion, and 4) absence of the lead point. Conservative management with US monitoring rather than an immediate operation is recommended for those patient with typical transient small bowel intussusceptions. Atypical US findings or clinical deterioration of the patient with persistent intussusception warrant surgical exploration.
