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.
Aim: To compare clinical success and complications of uncovered self-expanding metal stents (SEMS) vs covered SEMS (cSEMS) in obstruction of the small bowel.
Methods: Technical success, complications and outcome of endoscopic SEMS or cSEMS placement in tumor related obstruction of the duodenum or jejunum were retrospectively assessed. The primary end points were rates of stent migration and overgrowth. Secondary end points were the effect of concomitant biliary drainage on migration rate and overall survival. The data was analyzed according to the Strengthening the Reporting of Observational Studies in Epidemiology guidelines.
Results: Thirty-two SEMS were implanted in 20 patients. In all patients, endoscopic stent implantation was successful. Stent migration was observed in 9 of 16 cSEMS (56%) in comparison to 0/16 SEMS (0%) implantations (P = 0.002). Stent overgrowth did not significantly differ between the two stent types (SEMS: 3/16, 19%; cSEMS: 2/16, 13%). One cSEMS dislodged and had to be recovered from the jejunum by way of laparotomy. Time until migration between SEMS and cSEMS in patients with and without concomitant biliary stents did not significantly differ (HR = 1.530, 95%CI 0.731-6.306; P = 0.556). The mean follow-up was 57 ± 71 d (range: 1-275 d).
Conclusion: SEMS and cSEMS placement is safe in small bowel tumor obstruction. However, cSEMS is accompanied with a high rate of migration in comparison to uncovered SEMS.
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.
A rare cause of recurrent melena was identified by capsule endoscopy: arteriovenous malformation
(2013)
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.
The case of an 80-year-old female patient with recurrent melena and anemia is presented here by the authors. Endoscopy of the upper gastrointestinal tract as well as ileocolonoscopy did not show any pathological findings. CE revealed an area with abnormal mucosa in the middle third of the small bowel, which was strongly suspected of having malignant origin. Surgical exploration led to resection of a small jejunal segment with a palpable mass and increased blood flow. Surprisingly, the final diagnosis determined by the pathologist was arteriovenous malformation (AVM). This article is part of an expert video encyclopedia.
Operatively altered anatomy such as Billroth II gastroenterostomy represents a challenge in endoscopic retrograde cholangiopancreatography and might require dedicated instruments. In this article, the authors demonstrate the technique of endoscopic retrograde cholangiography and sphincterotomy in a patient with Billroth's operation-II. Sphincterotomy is performed with a specially designed Billroth papillotome to enable papillotomy in the direction of the papillary roof. This article is part of an expert video encyclopedia.
Dieulafoy's lesion (DL) is a rare source of gastrointestinal tract bleeding that may occur at any site in the gastrointestinal tract and may be difficult to detect by endoscopy. DL is characterized by a large, tortuous arteriole in the submucosa. This is a case of duodenal DL that is detected and treated by endoscopy. This article is part of an expert video encyclopedia.
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.
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.
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.
Operatively altered anatomy might provide a challenge for endoscopic retrograde cholangiopancreatography. However, with the support of the balloon-assisted enteroscopy technique the access route to the biliary system even in long-limb Roux-Y anastomosis is feasible in most cases.
In this video case report, an 81-year-old woman was symptomatic for stone obstruction of the common bile duct (CBD). Complete gastrectomy had been performed in this patient for stomach cancer many years earlier. Balloon-assisted enteroscopy was used for retrograde access of the duodenum via a Roux-Y anastomosis. There was major difficulty in intubating the CBD via the native papilla in this case because access was prevented by the tangential approach of the enteroscope. After performing an incomplete papillectomy, the insertion of a guidewire into the CBD was feasible and the bile duct stone was removed. This article is part of an expert video encyclopedia.
