Angiodysplasia of small bowel is uncommon and frequently undiagnosed and presents a taxing surgical problem. It is usually diagnosed for unexplained gastrointestinal bleeding. For the surgeon, the main technical problem is that the lesion is impalpable, and invisible to the naked eye, so it usually cannot be identified unless bleeds actively at the time of surgery. Arteriography gives a little information about wax and wane pattern of bleeding in the lesion. Endoscopy is often unfruitful because the majority of lesions are submucosal and rarely exceed a few millimeters in diameter. Transillumination of the intestinal wall from inside of the lumen to the outside in a dark room can define the precise vascular anatomy of the wall. The delicate lesion of the angiodysplasia can be identified by this transillumination method. We described a simple intraoperstive endoscopic translllumination technique used successfully to identify an angiodysplasia in the small bovwel prior to the bowel resecion. This report summarized our experience and review of literature.

Angiodysplsia of the small bowel is uncommon, but provably remains frequently undiagnosed. In the small intestine, angiodysplasia presents a taxing surgical problem and is uauslly diagnosed for unexplained gastrointestinal bleeding. For the surgeon, the main technical problem is that even when identified by frequently impalpable, and invisible to the naked eye unless they are actively bleeding at the time of surgery. Ensocopy is often unfruitful because the majority of lesions are submucosal and rarely exceed a few milimeters in diameter. We described a simple intraoperative endoscopic transillumination technique used successfully to identify an angiodysplasia in the jejunum prior to the small bowel resection. This report summarized our experience and review of literature.

BACKGROUND/AIMS: Substantial time and attention are required to read and interpret the recordings of capsule endoscopic images. A suspected blood identification system (SBIS) has been developed to assist in the reading of capsule images. This software automatically marks "red tags" that correlate with suspected blood or red areas. However, the sensitivity and accuracy of the system have not been well characterized. We investigated the usefulness of the SBIS in capsule endoscopy according to various small bowel bleeding lesions. METHODS: Two expert endoscopists reviewed the capsule images. Angiodysplasias, ulcers and erosion were considered as significant lesions, and active bleeding lesions were considered when bleeding or blood clots were seen in the capsule images. The red tags that were automatically marked by the use of the rapid software were compared to the significant lesions reviewed by the endoscopists. RESULTS: A total of 95 patients were enrolled in the study. The endoscopists identified 159 significant lesions and 71 lesions marked by red tags were identified by the SBIS. Among the 71 lesions, 31 lesions correctly coincided with the significant lesions. The overall sensitivity and positive predictive value of the use of the SBIS were 20% and 44%, respectively. The sensitivities of active ulcers and active bleeding lesions were 83% and 93%, respectively. CONCLUSIONS: The SBIS should be considered as a rapid screening tool to identify active bleeding lesions, and a complete review of capsule images by a physician is still needed.

Angiodysplasia has been recognized as an important cause of lower gastrointestinal bleeding, but it is difficult to confirm the lesions. Angiodysplasia in the small bowel could be the most probable cause of bleeding particularly in the elderly patients when usual methods fail to document the focus. Small bowel angiodysplasias have been diagnosed by angiography and/or surgery at the sites where usual endoscope could not reach, and treated by medical therapy, angiographic embolization or surgery. We experienced a case of a bleeding angiodysplasia in the terminal ileum in a 51-year-old man who was taking anti-platelet agents. The lesion was diagnosed by colonoscopy, and bleeding was easily controlled with hemoclipping.

Gastric angiodysplasia is an uncommon cause of upper gastrointestinal blood loss that may occur in the stomach or duodenum, and is responsible for up to 1~6% of upper gastrointestinal bleeding. In contrast to colonic angioectasia, gastric lesions are more common in young individuals and originate from developmental causes. On an endoscopic examination, the lesions typically show a spider-shape or coral reef-like pattern of dilated and tortuous vessels and measure approximately 2 to 10 mm in diameter. We encountered a case of huge gastric angiodysplasia that presented with overt bleeding and anemia and was successfully treated with argon plasma coagulation.

BACKGROUND/AIMS: No clear data have been established and validated regarding whether rectal retroflexion has an important and therapeutic impact. The aim of the present study was to evaluate the diagnostic yield and therapeutic impact of rectal retroflexion compared with straight view examination. METHODS: A prospective single-blind study was conducted. Consecutive patients evaluated between October 2011 and April 2012 were included. RESULTS: A total of 934 patients (542 women, 58%) were included. The mean age was 57.4+/-14.8 years. Retroflexion was successful in 917 patients (98.2%). Distinct lesions in the anorectal area were detected in 32 patients (3.4%), of which 10 (1%) were identified only on retroflex view and 22 (2.4%) on both straight and retroflex views. Of the 32 identified lesions, 16 (50%) were polyps, nine (28.1%) were angiodysplasias, six (18.8%) were ulcers, and one (3.1%) was a flat lesion. All 10 patients (1%) in whom lesions were detected only by rectal retroflexion showed a therapeutic impact. CONCLUSIONS: Rectal retroflexion has minimal diagnostic yield and therapeutic impact. However, its low rate of major complications and the possibility of detecting lesions undetectable by straight viewing justify its use.

BACKGROUND/AIMS: There is no consensus as to the best treatment for non-variceal, non-ulcer gastrointestinal hemorrhage. Endoscopic band ligation is an inexpensive, readily available, and easily learned technique in contrast to conventional thermal methods of endoscopic hemostasis. The purpose of this study is to define the effectiveness of endoscopic band ligation for non-variceal, non-ulcer gastrointestinal hemorrhage and post-polypectomy hemorrhage. METHODS: Twenty eight patients were treated by band ligation between July 1996 and October 2000. The lesions treated were: Dieulafoy's lesion in 13, Mallory-Weiss tear in 7, angiodysplasia in 1, post-polypectomy bleeding in 4, post-endoscopic mucosal resection bleeding in 2, post-endoscopic biopsy bleeding in 1. RESULTS: Endoscopic band ligation was successful in 25 of 28 cases. Additional sclerotherapy was necessary in two cases of Dieulafoy's lesion. The remaining case was early band detachment. CONCLUSIONS: Endoscopic band ligation is effective for non-variceal, non-ulcer bleeding. It has the advantage of ease of use and is relatively inexpensive.

Appendiceal causes of lower gastrointestinal bleeding are rare, and identification of the bleeding site is critical. Identification of the bleeding site can be difficult. The differential diagnosis of bleeding in the appendix includes diverticulum, appendicitis, angiodysplasia, Crohn's disease, and appendiceal intussusception, which leads to mucosal erosion and vascular exposure by underlying inflammation. Laparoscopic surgery is commonly performed as a therapeutic procedure for the appendix, also can be a valuable tool in the diagnosis and treatment of hemorrhaging from the appendix. Appendiceal bleeding is rare, and laparoscopic management cases are not widely reported. Herein, we report a case of successful laparoscopic management of appendiceal bleeding diagnosed by colonoscopy with a review of the literature.
