The Retrospective Analysis Of The Capsule Endoscopy Studies On 1642 Cases Of Patients

AIM:The different capsule capsule endoscopy system of clinical application results are compared through the retrospective analysis of the capsule endoscopy studies on 1642 cases of patients, including the Given M2A video capsule systerm (Given Imaging Ltd., Yoqneam, Israel) and OMOM capsule endoscopy (Jinshan science and technology company, Chongqing, China), also we analyse the special age level patient's disease distributed situation, including smaller than 18 years old age groups,60-80 year-old age group and older than 80 years old patients.METHODS:We study 1642 patients who underwent capsule endoscopy during June 2003 to December 2009 in The First Affiliated Hospital, College of Medicine, ZheJiang University, and carries on the revisit different to all patients, the revisit time from one year to seven years. Among 1037 cases patients with The M2A CE inspected, the female is 394 cases, the male is 643 cases,age between 7-91 years old, average age 49.2 years old, the OMOM CE inspect the patients 605 cases, the female 268 cases, the male 337 cases,, Summarizes the above inspector's material to carry on the statistical analysis.RESULTS:In the 1037 cases patients who is inspected by The M2A CE, the inspection success rate is 98.65%; ratio of the entire samll bowel was achieved is 93.34%; ratio of positive finding is 57.86%. capsule detention rate is 1.35%. In the 605 cases patients who is inspected by The OMOM CE, the inspection success rate is 97.35%; ratio of the entire samll bowel was achieved in 89.92%; ratio of positive finding is 56.03%. capsule detention rate 2.81%. After x2 the examination, between the M2A CE and the OMOM CE.the results of the ratio of the entire samll bowel was achieved and capsule detention compared is P<0.05, the difference has certain significance, explain that the ratio of the entire samll bowel was achieved of the OMOM CE is Less than the M2A CE, and easy to have the capsule detention. While the ratio of inspection success and the ratio of positive finding compared P> 0.05, there was no obvious difference. Each group comparison:Unexplained gastrointestinal bleeding groups of patients, capsule detection rate, diagnosis rate and the ratio of the entire samll bowel was achieved compared, P> 0.05, are no obvious difference.Unexplained abdominal distention nausea and vomiting and (or) diarrhea patient groups of patients, the inspection success ratio and the ratio of positive finding compared P> 0.05, and the ratio of the entire samll bowel was achieved compared:P< 0.05, have certain differences. And TiJianZu patients and to parenteral performance mainly imported capsule inspection group of patients with homebred the inspection success ratio and the ratio of the entire samll bowel was achieved compared all show that P> 0.05, no obvious difference is visible.The children group patients (smaller than 18 years old), the most common intestinal diseases is crohn's disease, Accounted for 32.95% of patients with inspected success , followed by intestinal nonspecific inflammation, Accounted for 7.95% of patients with inspected success,small intestine lymphoid follicles excessive proliferation, accounting for 6.8%, tuberculosis accounts for 5.68%, vascular malformation of 3.4%, intestinal tapeworm accounted for 3.4%, Meckel diverticula companion hemorrhage of 3.4%, small villi with atrophy of 2.3%, and primary small intestinal lymphatic outspread disease, purple big bubble syndrome congenital diseases are is rare, accounting for pesticides. But 60-80 elderly patients with clinical manifestations in gastrointestinal bleeding for common, accounting for the total number of 65%, the distribution of intestinal diseases respectively:the small intestinal angiodysplasia accounts for 41%, Followed by intestinal malignant tumor (including mesenchymal tumor adenocarcinoma, lymphoma, etc.), accounted for 6.97%; GouChongBing and crohn's disease 5.09%as accounted for, Small intestine benign tumor (including polyps, lipoma, xanthoma etc) accounted for 3.48%, tuberculosis accounts for 2.68%; Small intestine nonspecific inflammation accounts for 2.41%; Small intestine lymphatic outspread disease of 2.14%; Ischemic bowel disease of 1.88%; Chyle purging of 0.8%; Diverticula accounted for 0.5%, radioactive enteritis, portal hypertension sex bowel disease, abdominal aortic burst of each 0.27%. In elderly patients (>80 years), the gastrointestinal bleeding for common, the distribution of intestinal diseases for:small intestinal angiodysplasia of 9.3%, followed by ischemic bowel disease of 14.4%, then for GouChongBing accounted for 11.8%, intestine nonspecific inflammation accounts for 8.8%, diverticula companion hemorrhage of 5.9%, Bowel cancer accounted for 2.94%.CONCLUSIONS:1,The capsule endoscopy studies the OMOM CE capsule retention rate and the ratio of the entire samll bowel wasn't achieved is higher than M2A CE, especially in intestinal illness caused inner-cinnabar fluctuate unobstructed degree have with abnormal, homebred capsule less through the blockage, reason suggests in clinical, consider crohn's disease, or obstruction history etc suspected patients with narrow may fluctuate as possible use of imported capsule endoscopy studies. But domestic capsule in import capsule compared, check the success ratio and pathological changes, diagnosis rate are similar detection rate, with similar diagnostic value.2,Disease distribution shows:children's patients, the most common intestinal diseases for crohn's disease, followed by intestinal nonspecific inflammation, then for small intestine lymphoid follicles excessive proliferation, tuberculosis, Meckel diverticula with bleeding, tao helminth disease, while the primary small intestinal lymphatic outspread disease, purple big bubble syndrome congenital diseases are more rare. For 60-80 year old for patients with small intestinal angiodysplasia most common, followed by intestinal malignant tumor (including mesenchymal tumor adenocarcinoma, lymphoma, etc.), small intestinal GouChongBing and crohn's disease proportion of similar, ranked third in the world. Then for small intestine benign tumor (including polyps, lipoma, xanthoma etc), tuberculosis, intestine nonspecific inflammation, intestine lymphatic outspread disease, ischemic bowel disease, etc. While in elderly patients, first for small intestinal angiodysplasia, followed by ischemic bowel disease, the third for GouChongBing, then for small intestine nonspecific inflammation, diverticula with bleeding, tumor rare, inflammatory bowel disease is not seen.
