RÉSUMÉ
Objective Dieulafoy's lesion is a rare cause of upper gastrointestinal bleeding. The purpose of this study was to recognize the clinical characteristics of gastric Dieulafoy and to identify possible predictive factors of rebleeding. Methods Retrospective study of patients with gastrointestinal bleeding secondary to Dieulafoy's lesion from January 2009 to June 2016. We analyzed the clinical data and endoscopic findings and the correlated with rebleeding risk factors with Dieulafoy's lesion. Results 111 patients were included in the study, 97 (87.4%) patients were male; the most common location of the bleeding lesions were Proximal stomach of 53 cases (47.7%); According to the Forrest type, 46.8% of the cases were arterial (spurting), 52.3% of the cases were arterial (oozing), there were 101 (91.0%) patients treated by endoscopic combined drug therapy. The success rate of Endoscopic hemostatic treatment was 84.2%, endoscopic hemostatic treatment success rate was as follows: single endoscopic, 85.0%; two endoscopic, 84.8%; three endoscopic, 75.0%. The hemostatic treatment success rate of 101 patients with endoscopic combined drug was as follows: Proximal stomach, 83.7%; mid-stomach, 82.1%; and distal stomach, 88.9%. Age (P = 0.002) and blood transfusion (P = 0.004) were risk factors for rebleeding in the study. Blood transfusion was associated with a higher recurrence rate for bleeding (P = 0.018, OR=37.77, 95% CI = 1.86~766.47) for 101 patients with endoscopic in combination with drug. Conclusion Endoscopic therapy is effective for treating Dieulafoy's lesion. The blood transfusion was associated with a high rate of bleeding recurrence. There were no significant differences between the rebleeding and non-rebleeding groups with respect to bleeding location or hemostatic methods.

Objective To observe the efficacy and safety of endoscopic variceal ligation (EVL) and esophageal variceal sclerotherapy (EVS) with different hardeners for esophageal variceal bleeding (EVB).Methods Clinical data of 314 patients with EVB were retrospectively reviewed.The patients were divided into 5 groups according to the endoscopic treatments they have received,i.e.,endoscopic variceal ligation (EVL) group (n =112),sodium morrhuate sclerotherapy (EVS1) group (n =48),lauromacrogol sclerotherapy (EVS2) group (n =40),EVL plus sodium morrhuate sclerotherapy (EVLS1) group (n =26) and EVL plus lauromacrogol sclerotherapy (EVLS2) group (n =88).The efficacy,variceal recurrence rate and complication rate were evaluated.Results There was no significant difference in efficacy of stop bleeding among 5 groups,which was 85.7％ (96/112) in EVL group,83.3％ (40/48) in EVS1 group,92.5％(37/40) in EVS2 group,92.3％ (24/26) in EVLS1 group and 94.3％ (83/88) in EVLS2 group (P ＞0.05).The complete cure rates in EVLS1 group (88.5％,23/26) and EVLS2 group (87.5％,77/88)were significantly higher than those in 3 other groups (P ＜ 0.05).Rebleeding rates in EVS1 group (18.8％,9/48) and EVL group (11.6％,13/112) were significantly higher than those in other 3 groups (P ＜0.05).The patients were followed up for 6-18 months,and the varices recurrence rate was highest in group EVL (23.2％,26/112) and lowest in EVLS2 (10.2％,9/88,P ＜0.05).The complication rate in group EVS1 (32.2％,49/152) was significantly higher than that in other 4 groups (P ＜0.05).Conclusion EVL plus EVS,either with sodium morrhuate or lauromacrogol EVS is safe and effective for EVB,especially EVL plus Lauromacrogol EVS,may become an optimal therapy to control esophageal variceal bleeding and rebleeding.
RÉSUMÉ
ObjectiveTo unify the definitions of colonoscopic characteristics of Crohn disease (CD) and intestinal tuberculosis ( ITB),and to evaluate colonoscopic and clinical features in the differential diagnosis of CD and ITB.MethodsA collaborative group composed of 10 experts from 5 hospitals voted to identify and confirm the colonoscopic characteristics.Clinical and colonoscopic characteristics were analyzed,thereafter,characteristics were scored based on different diagnostic specificity.ROC curve was used for determining the cutoff point to differentiate CD from ITB.ResultsFirstly,standard endoscopic images and descriptions were determined.Secondly,colonoscopic parameters which were significantly different between the CD and ITB patients included the follows:involvement of more than four intestinal segments,anorectal involvement,longitudinal ulcers,cobblestone appearance and transverse ulcers.Clinical findings which were significantly different between the CD and ITB patients included active pulmonary tuberculosis,PPD-test strong positive,anal fistula/perianal abscess and extra-intestinal manifestations in CD.4.4％(6/136) patients were confirmed by histological evidence of caseating granulomas.By using our scoring system,39.7％ (54/136) confirmed diagnoses and 18.4％ (25/136) suspected diagnoses were made in patients without histological evidence.ConclusionIdentification of colonoscopic characteristics and unification of the colonscopic diagnostic criteria were helpful in the differential diagnosis between CD and ITB.The differential diagnosis rate could he improved by using the scoring system.Half cases could not be confirmed even with combined pathology and the scoring system,so a more comprhensive scoring system would be warranted.

Objective To investigate the difference of clinical features between primary colorectal malignant T cell lymphoma and primary colorectal malignant B cell lymphoma.Methods Forty cases diagnosed as primary eolorectal malignant lymphoma (PCML) between Jan 1999 and May 2008 were studied retrospectively.Results The average age of 40 patients with PCML was (41.0±11.2) years old.Twenty-seven cases (67.5%) were diagnosed as B-cell lymphoma.Thirteen cases (32.5%) were diagnosed as T-cell lymphoma.Patients with T-cell lymphoma in PCML had more symptoms such as fever,night sweat and hematochezia,and was easier to perforate than those with B-cell lymphoma.Protrude type and single-focus and right-colon type were common in B-cell lymphoma under colonoscopy,but ulcerative type and multi-focus and fulbcolon were common in T-cell lymphoma.B-cell lymphoma had an earlier diagnosis,and more opportunities for surgery than T-cell lymphoma.Conclusions The misdiagnostic rate for PCML was high.Protrude type and single-focus and right-colon type were common in B-cell lymphoma under eolonoscopy,but ulcerative type and multi-focus and full-colon were common in T-cell lymphoma.B-cell lymphoma could be diagnosed earlier.
