Small bowel endoscopy is indicated for patients with an unidentified bleeding site in esophagogastroduodenoscopy and ileocolonoscopy and symptoms of intestinal blood loss or unexplained anemia. In approximately two-thirds of these cases, capsule endoscopy (CE) detects a lesion within the small bowel that explains the patient's symptoms. In few cases, though, lesions outside of the small bowel might be revealed by CE. Therefore, attention to all intestines that are visualized by CE might be necessary not to overlook bleeding sites that had not been discovered by prior flexible endoscopy.
Here the case of a 71-year-old male patient with unexplained anemia is presented by the authors. Small-bowel CE revealed minor bleeding from a neoplastic mass in the cecum. The final diagnosis of an adenocarcinoma of the ascending colon was established after the patient underwent a right hemicolectomy. This article is part of an expert video encyclopedia.
This is an example of capsule endoscopy (CE) revealing terminal ileitis in an young male patient with recurrent abdominal pain who had previously been investigated with colonoscopy and esophagogastroduodenoscopy without any significant findings. CE revealed severe inflammation of the terminal ileum. This article is part of an expert video encyclopedia.
In this article, the video demonstrated is an example of a 76-year-old male patient who presented with recurrent intestinal bleeding of unknown origin at the university hospital. Previously performed upper and lower gastrointestinal tract endoscopy did not reveal a bleeding lesion. Capsule endoscopy revealed small-bowel angiectasia that were treated by argon plasma coagulation at subsequent balloon enteroscopy. This article is part of an expert video encyclopedia.
This is the case report of a 58-year-old male patient who presented with recurring abdominal pain of 4 months duration. He had undergone multiple investigations including upper and lower gastrointestinal tract endoscopies and diagnostic laparoscopy, but there were no significant findings detected.
Capsule endoscopy revealed a submucosal small bowel tumor that was suspected to originate from the distal third of the small bowel. Surgery was indicated and a highly differentiated neuroendocrine tumor was found at laparotomy at the distal ileum. An ileocecal resection was performed confirming a neuroendocrine tumor of the small bowel (G2T2N1M1). This article is part of an expert video encyclopedia.
Small bowel endoscopy is indicated for patients with an unidentified bleeding site in esophago-gastro-duodenoscopy and ileo-colonoscopy and symptoms of intestinal blood loss or unexplained anemia. In approximately two-thirds of these cases, capsule endoscopy (CE) detects a lesion within the small bowel that explains the patient's symptoms. In few cases, though, lesions outside of the small bowel might be revealed by CE. Therefore, attention to all intestines that are visualized by CE might be necessary not to overlook bleeding sites that had not been discovered by prior flexible endoscopy.
The authors present the case of a 71-year-old male patient who presented to their outpatient clinic for unexplained anemia. Small bowel CE revealed minor bleeding from an adenocarcinoma in the cecum. This article is part of an expert video encyclopedia.
Peutz–Jeghers syndrome (PJS) is a rare autosomal-dominant inherited disorder characterized by gastrointestinal hamartomas, mucocutaneous pigmentation, and an elevated cancer risk. Moreover, intussusception risk may be as high as 50% at the age of 20 years and is caused by large polyps. There is some evidence that endoscopic surveillance of PJS patients with removal of small intestinal polyps with a diameter of more than 15 mm efficiently prevents intussusceptions. In recent years, capsule endoscopy (CE) has largely replaced small-bowel radiography techniques to screen for small-bowel polyps. Magnetic resonance imaging may be equally efficient as CE for screening of large polyps. Balloon enteroscopy may be used for endoscopic snare resection of polyps.

Stent insertion is an established technique of endoscopic retrograde cholangiopancreatography (ERCP) to treat symptomatic malignant or benign biliary strictures, and stent placement is accomplished by using the over-the-wire (OTW) method. In some cases, however, it might be challenging and sometimes time consuming to pass a complex biliary stricture with the guidewire. Stent-exchange technique with a guidewire left in place during stent removal might therefore be helpful to guarantee successful and time-sparing interventions.
A simple method is presented to remove the stent with the guidewire left in place, using the OTW stent-exchange method in ERCP. This technique simplifies stent OTW exchange by using a simple endoscopy snare. This article is part of an expert video encyclopedia.
The small intestine is a part of the gastrointestinal tract in which digestion and absorption of nutrients takes place. The small bowel follows the stomach and is followed by the large intestine, reaching from the pylorus to the valve of Bauhin and is separated into the duodenum, the jejunum, and the ileum.
Capsule endoscopy (CE) has the potential to offer a perfect overview of the small-bowel mucosa and complete visualization of the entire small bowel is achieved in most cases. In this video, there is an overview offered on normal findings in small-bowel CE and typical anatomical landmarks are indicated. This article is part of an expert video encyclopedia.
Small bowel tumors are detected in approximately 10% of patients with small bowel endoscopies for obscure or overt mid-intestinal bleeding. Small bowel tumors may be of malignant or benign etiology. Malignant etiologies include adenocarcinoma, neuroendocrine tumors, or lymphoma, whereas benign lesions are typically lipomas, inflammatory polyps, or adenomas. Within the group of nonneoplastic lesions inflammatory polyps are most frequent. Significant bleeding and bowel obstruction due to intussusception might occur, and surgical or endoscopic treatment has been reported for symptomatic patients. A case is demonstrated with an inflammatory fibroid polyp detected by capsule endoscopy and confirmed by balloon enteroscopy. This article is part of an expert video encyclopedia.
Here the authors report the case of an elderly woman who had upper abdominal pain, upper gastrointestinal hemorrhage, and jaundice (a symptomatic triad termed the ‘Quincke’ triad) a few days after endoscopic sphincterotomy. Abdominal ultrasonography demonstrated an echo-rich filling of the choledochus consistent with hemobilia. Endoscopic retrograde cholangiography was immediately performed and blood clots were removed from the common bile duct. A nasobiliary catheter was placed to irrigate the bile duct for prevention of recurring obstruction of the bile ducts from blood clots. Further follow-up of the patient was uneventful.
