Diagnostic yield of 335 push video-enteroscopies.

BACKGROUND AND OBJECTIVES: The diagnostic yield of push enteroscopy (PE) varies widely from 13 to 78% of cases, according to the various series. The aim of this retrospective cohort study was to determine the endoscopic and histological yield of PE in our health area. PATIENTS AND METHODS: A total of 355 consecutive patients (190 males/165 females; mean age 45 years, range 15-89) underwent PE over a 6-year period, from 1997 to 2003. PE was performed under sedation and without overtube. Small-bowel mucosa biopsies were taken in 199 explorations (56%). Clinical indications for PE included: chronic diarrhea (35%), occult digestive bleeding (ODB) or iron-deficiency anemia (28%), suspected small-bowel malignancy (16%), chronic abdominal pain (28/355; 8%), follow-up of polyposis or malabsorption syndromes (7%), and abnormal radiographic findings (6%). RESULTS: PE detected lesions in 122 cases (34%); in 6 cases (6%) lesions were within the reach of esophagogastroduodenoscopy. A normal macroscopic appearance of the small intestinal mucosa with an abnormal histological study was seen in 16 patients (6%). Major findings included: malabsorptive diseases (14%), nonspecific enteropathy (5%), angiodysplasia (3,5%), lymphangiectasia (3%); jejunal polyps (2%), Crohn s disease (2%), intestinal tumors (2%), extrinsic jejunal strictures (0.5%), and other (10/355; 3%). Abnormal radiographic findings (62%), chronic diarrhea (37%) and ODB (31%) were the indications with a higher diagnostic yield. No major complications were seen. CONCLUSIONS: According to our experience, PE is a safe and useful tool for the evaluation of small-bowel disease, especially in some indications (abnormal radiographic findings, chronic diarrhea, and ODB). Small-bowel biopsy increases PE's diagnostic yield in patients with chronic diarrhea.

Previously unknown stricture due to radiation therapy diagnosed by capsule endoscopy.

Radiation enteritis is a complex clinical entity secondary to the affectation of intestinal epithelial cells as a result of radiation in the management of pelvic malignancies that may occasionally cause intestinal strictures. We present the case of a 60 year-old woman who had been diagnosed ten years before with endometrial adenocarcinoma, and who underwent hysterectomy with double adnexectomy and subsequent radiation therapy. The patient consulted for abdominal pain and ferropenic anemia of several years standing, and had negative results following radiographic and endoscopic conventional techniques, reason why she was subjected to a capsule endoscopy study that revealed the presence of an ulcerated ileal stricture, which caused the asymptomatic retention of the capsule within the ileum. A laparotomy was subsequently performed--the strictured segment was resected and the capsule retrieved. The histologic examination of the resected segment confirmed the capsule endoscopy-raised suspicion of radiation enteritis. This case shows the role capsule endoscopy may play in the diagnosis of this condition.

Wireless endoscopy.

Wireless endoscopy consists of a small-sized device which allows gastrointestinal tract images to be taken as it physiologically advances along its lumen after being orally ingested. Its primary contribution is the study of small bowel conditions, a gastrointestinal tract segment in which diagnosis difficulties still arise when using current tests, including enteroscopy. Preliminary studies in animals and healthy subjects have revealed data on image quality, sensitivity, specificity, and safety that demonstrate the benefits of this new technique. This review discusses technical aspects, indications and contraindications, as well as studies reported so far on this endoscopic diagnostic procedure.

[Sump syndrome. Treatment by endoscopic biliary "rendez-vous" procedure].

Sump syndrome consists on an entity in which the distal portion of the biliary tree does not drainage by the major papilla, so food and bile are retained and infections could appear leading to cholangitis. The real incidence of the sump syndrome after side-to-side choledocoduodenostomy is unknown, but has been described less than 10%. Several procedures have been used to solve it but at present endoscopic sphincterotomy is of choice the treatment of this condition that is followed by a good outcome. When major papilla can not be negotiated, an endoscopic approach consisting in a biliary endoscopic < > procedure could be used, negotiating the biliary tree by the side-to-side choledocoduodenostomy in this case. We report a clinical case of a patient with a side-to-side choledocoduodenostomy because of choledocolithiasis who developed a sump syndome. He was treated by a biliary endoscopic < > procedure because a papillary stenosis did not allow a transpapillar access to the biliary tree.

Endoscopic pancreatic stent drainage improves pain in chronic pancreatitis.

UNLABELLED: Pain in chronic pancreatitis is due to intraglandular neural affection and to pancreatic duct drainage obstruction with an increased intraductal pressure. To achieve pain relief, medical, surgical and endoscopic procedures have been developed. AIM: To evaluate the efficacy of pancreatic duct stenting in patients with narcotic-dependent pain due to chronic pancreatitis. PATIENTS AND METHOD: From May-1994 to May-1996, ten patients (medium age: 47.5 yr) with alcoholic chronic pancreatitis were selected for this procedure. Pancreatography showed single or multiple Wirsung strictures in all cases. Papillotomy and pancreatic duct sphincterotomy were performed before stenting. Strictures were negotiated with a 7F dilating catheter over a guide wire, and intraductal calculi were removed as well. We used 7F plastic stents with variable lengths (5-10 cm), that were exchanged when the patient presented pain recurrence. Stent survival time was defined as the patient's pain-free time. RESULTS: In 6 of the 10 patients stent placement was carried out successfully. A single distal Wirsung stricture was diagnosed in 3 patients while in the remaining 3 there were several strictures associated to ductal lithiasis in two of them. Mean time to achieve pain relief was 3 days and mean stent survival time was 166.5 days. There were no complications due to the procedure. CONCLUSIONS: When placed through the stricture, endoscopic pancreatic stent drainage is effective in achieving pain relief. It is a safe procedure with no complications in our short series.

Endoscopic stenting in the management of malignant biliary obstruction.

UNLABELLED: A relevant percentage of patients with malignant biliary obstruction are not candidates for surgery when the diagnosis is made. Endoscopically placed biliary stents have shown their efficacy in the palliative management of these patients although they do not seem to increase their survival. We report on a retrospective analysis of 37 patients with malignant biliary obstruction treated with endoscopic biliary stents. The distal third (62%) of the main life duct was the most frequent common location for the obstruction, and pancreatic cancer was the most frequent cause of obstruction (64%). Twenty three plastic (13-7F and 10-10F) and 14 metallic stents were placed initially. Forty four percent of the plastic stents (all of them 7F, none 10F) were removed after 39 days against 30% of the metallic stents after a mean period of 60 days. Global survival was 153 days (110 in the plastic stents' group versus 195 in the metallic one, p: NS). We could only make a complete follow up in 52% of the patients. CONCLUSIONS: endoprotheses are a good palliative treatment for malignant biliary obstruction. When plastic stents are used they should have a wide calibre (10F or greater). Metallic stents result in an increase of survival time without statistical significance.

[A retroperitoneal abscess after endoscopic sphincterotomy: a severe and infrequent complication].

We report the case of a 55-year-old female patient, previously cholecystectomized, who was admitted to the Hospital because of recurrent biliary abdominal pain, cholestasis and common bile duct enlargement by ultrasonography. 48 hours after an endoscopic sphincterotomy the patient developed abdominal pain and fever. CT scan demonstrated air and an infected liquid collection in the retroperitoneum. Although a percutaneous drainage was attempted, the persistence of the symptoms and the low drainage outflow of the infected material made surgical treatment necessary. Duodenal perforation in endoscopic sphincterotomy is an unusual but severe complication that leads to a high mortality rate if surgical treatment is not applied promptly. Sometimes retropneumoperitoneum can be satisfactory solved just with a conservative medical therapy, but if there is a suspected or confirmed infected collection surgical treatment must be applied promptly.

[The assessment of colonic polyps found via colonoscopy].

AIM: To evaluate the histopathological characteristics of colonic polyps, found during colonoscopy examination and endoscopic polypectomy, and their relation to age, tumor location, sex, histological type and degree of epithelial dysplasia. MATERIAL AND METHODS: Between 1996 and 1997, 2,465 total colonoscopies were performed at the Gastroenterology Department of the Virgin Macarena University Hospital in Seville. Different size polyps were found in 318 patients who had been referred because of several symptoms/by several centers. The mean age was 59.2 years in men and 61.5 years in women. RESULTS: 446 polyps were removed by endoscopic polypectomy, 32 (7.2%) were hyperplastic polyps, 402 were adenomas (90.2%) and 12 (2.6%) were adenomas with adenocarcinoma. Seventy-five percent of adenomas were located in the left colon and rectum and 25% in right colon. Hyperplastic polyps were found in left colon. Of the polyps removed, 55.1% were smaller than 1 cm, 26.5% were between 1 and 2 cm and 18.4% were between 2 and 7 cm. Histopathologic study of adenomas revealed that 17% were villous adenoma, 80% were tubular adenomas and 3% were tubulovillous adenomas. Adenocarcinomas were found in 12 (2.8%) adenomas. Of the adenomatous polyps, 87.4% had low-grade dysplasia and 12.6% high-grade dysplasia. Statistical analysis showed a strong correlation between size of adenoma and degree of dysplasia (p < 0.05). Similar significant relation was found between histological type and size (p < 0.05) but there were no statistically significant differences between location, sex or age, and degree of dysplasia (p < 0.05). CONCLUSIONS: Size of colonic polyps is related to epithelial dysplasia and histological type (p < 0.05). No correlation was found between location, sex or age and degree of dysplasia.
