Project description:Endoscopic band ligation (EBL) has been used to achieve hemostasis in patients with colonic diverticular bleeding. The safety and effectiveness of EBL when performed by non-expert endoscopists have not been sufficiently verified. This study aimed to elucidate the feasibility of the EBL technique when performed by non-expert endoscopists and of considering EBL as a standard treatment for colonic diverticular bleeding.A retrospective cohort study was conducted in a tertiary referral center in Tokyo, Japan, between June 2009 and October 2014. A total of 95 patients treated with EBL were included in the study and were divided into two groups according to whether they had been treated by expert or non-expert endoscopists. Comorbidities, medications, shock index, hemoglobin level on admission, location of the bleeding diverticula, rate of bowel preparation, procedure time, and EBL-associated adverse events were evaluated in each group. Multivariate linear regression analyses were used to investigate factors related to EBL procedure time, which is the time elapsed between marking the site of bleeding with hemoclips and completion of the band release.A total of 47 (49.5 %) procedures were performed by expert endoscopists. In a bivariate analysis, the median EBL procedure times in the expert and non-expert groups were 15 minutes (range 4 - 45) and 11 minutes (range 4 - 36), respectively (P = 0.03). When a multivariate linear regression model was used, EBL for right-sided diverticula was the factor most significantly affecting EBL procedure time. No adverse events were encountered.EBL can be safely and effectively performed by non-expert endoscopists. A right-sided location of diverticula was the factor most significantly affecting EBL procedure time.

Project description:BACKGROUND : Prior studies have shown the effectiveness of both endoscopic band ligation (EBL) and clipping for colonic diverticular hemorrhage (CDH) but have been small and conducted at single centers. Therefore, we investigated which was the more effective and safe treatment in a multicenter long-term cohort study. METHODS : We reviewed data for 1679 patients with CDH who were treated with EBL (n = 638) or clipping (n = 1041) between January 2010 and December 2019 at 49 hospitals across Japan (CODE BLUE-J study). Logistic regression analysis was used to compare outcomes between the two treatments. RESULTS : In multivariate analysis, EBL was independently associated with reduced risk of early rebleeding (adjusted odds ratio [OR] 0.46; P < 0.001) and late rebleeding (adjusted OR 0.62; P < 0.001) compared with clipping. These significantly lower rebleeding rates with EBL were evident regardless of active bleeding or early colonoscopy. No significant differences were found between the treatments in the rates of initial hemostasis or mortality. Compared with clipping, EBL independently reduced the risk of needing interventional radiology (adjusted OR 0.37; P = 0.006) and prolonged length of hospital stay (adjusted OR 0.35; P < 0.001), but not need for surgery. Diverticulitis developed in one patient (0.16 %) following EBL and two patients (0.19 %) following clipping. Perforation occurred in two patients (0.31 %) following EBL and none following clipping. CONCLUSIONS : Analysis of our large endoscopy dataset suggests that EBL is an effective and safe endoscopic therapy for CDH, offering the advantages of lower early and late rebleeding rates, reduced need for interventional radiology, and shorter length of hospital stay.

Project description:Endoscopic band ligation (EBL) has been used for hemostasis of colonic diverticular hemorrhage. However, early rebleeding (< 30 days after EBL) has been reported in some cases. The aim of this study was to elucidate risk factors for early rebleeding after EBL in treatment of colonic diverticular hemorrhage.A total of 101 patients with definite diverticular hemorrhage treated using EBL from June 2009 to October 2014 were included in the retrospective cohort study and divided into rebleeding and non-rebleeding groups, depending on the presence or absence of early rebleeding. Patients' ages, comorbid diseases, stigmata of recent hemorrhage (SRH) [active bleeding (AB), non-bleeding visible vessel (NBVV), or adherent clot (AC)], locations of bleeding diverticula, and eversions of the diverticula after EBL were retrospectively evaluated in each group.Early rebleeding occurred in 15 cases. The median time (range) of early rebleeding occurrence was 5 days (range, 2 h to 26 days). Early rebleeding could be managed conservatively and/or endoscopically, except in one case in which surgery was done. Multivariate analysis revealed that age under 50 (adjusted OR, 8.7; 95 % CI 1.6 - 52.5; P = 0.014) and AB (adjusted OR, 4.21; 95 % CI 1.15 - 18.1; P = 0.03) were shown to be significant risk factors. The right side of the colon carried less risk than did the left side (adjusted OR, 0.21; 95 % CI 0.04 - 0.84; P = 0.028).Younger age, AB of SRH, and leftsided lesions were identified as the risk factors for early rebleeding after EBL in the treatment of colonic diverticular hemorrhage.

Project description:Long-term outcomes of endoscopic band ligation (EBL) for colonic diverticular hemorrhage have not been reported to date. The aim of this study was to determine the long-term outcomes of EBL and to retrospectively compare them with those of endoscopic clipping (EC) in the treatment of colonic diverticular hemorrhage.The study included patients with colonic diverticular hemorrhage who were treated with EBL or EC from January 2004 to November 2014 and followed up more than 1 year (61 patients in the EBL group and 39 patients in the EC group). Time-to-event analysis of rebleeding was performed with the Kaplan-Meier method. A follow-up colonoscopy was performed to confirm the disappearance of the banded diverticula in the EBL group.Rebleeding occurred in 21 patients in the EBL group and in 26 patients in the EC group. The cumulative incidence of rebleeding at 1, 12, 24, and 36 months after first treatments was 14 %, 23 %, 26 %, and 41 % in the EBL group and 38 %, 49 %, 59 %, and 68 % in the EC group, respectively. Time-to-event analysis revealed statistically significant data (Log-rank test, P = 0.0036). Scar formation with fold convergence at the previously banded site was observed in 11 of 24 patients who underwent follow-up colonoscopy (46 %). However, late rebleeding (rebleeding more than 30 days after EBL) occurred in five of these 11 cases.EBL was superior to EC in the treatment of colonic diverticular hemorrhage. However, the risk of rebleeding was not avoided even after the diverticula had been resolved using EBL.

Project description:BackgroundDirect and indirect clipping treatments are used worldwide to treat colonic diverticular bleeding (CDB), but their effectiveness has not been examined in multicenter studies with more than 100 cases.ObjectiveWe sought to determine the short- and long-term effectiveness of direct versus indirect clipping for CDB in a nationwide cohort.MethodsWe studied 1041 patients with CDB who underwent direct clipping (n = 360) or indirect clipping (n = 681) at 49 hospitals across Japan (CODE BLUE-J Study).ResultsMultivariate analysis adjusted for age, sex, and important confounding factors revealed that, compared with indirect clipping, direct clipping was independently associated with reduced risk of early rebleeding (<30 days; adjusted odds ratio [AOR] 0.592, p = 0.002), late rebleeding (<1 year; AOR 0.707, p = 0.018), and blood transfusion requirement (AOR 0.741, p = 0.047). No significant difference in initial hemostasis rates was observed between the two groups. Propensity-score matching to balance baseline characteristics also showed significant reductions in the early and late rebleeding rates with direct clipping. In subgroup analysis, direct clipping was associated with significantly lower rates of early and late rebleeding and blood transfusion need in cases of stigmata of recent hemorrhage with non-active bleeding on colonoscopy, right-sided diverticula, and early colonoscopy, but not with active bleeding on colonoscopy, left-sided diverticula, or elective colonoscopy.ConclusionsOur large nationwide study highlights the use of direct clipping for CDB treatment whenever possible. Differences in bleeding pattern and colonic location can also be considered when deciding which clipping options to use.

Project description:Background and aimsThe identification of stigmata of recent hemorrhage (SRH) in colonic diverticular bleeding (CDB) enables an endoscopic treatment and can improve the clinical outcome. However, SRH identification rate remains low. This study aims to investigate whether NOBLADS and Strate scoring systems are useful for predicting SRH identification rate of CDB pre-procedurally via colonoscopy.MethodsIn this single-center retrospective observational study, 302 patients who experienced their first episode of CDB from April 2008 to March 2018 were included. Patients were classified into SRH-positive and SRH-negative groups. The primary outcome was SRH identification rate. The secondary outcomes were active bleeding in SRH and early rebleeding rates. The usefulness of the NOBLADS and Strate scores as predicted values of SRH identification was evaluated using the area under the receiver operating characteristic curve.ResultsThere were 126 and 176 patients in the SRH-positive and SRH-negative groups, respectively. The area under the receiver operating characteristic curve for SRH identification using the NOBLADS score was 0.74 (95% confidence interval, 0.69-0.80) and that using the Strate score was 0.74 (95% confidence interval, 0.68-0.79). Active bleeding and early rebleeding rates increased according to each score. By setting the cut-off of the NOBLADS score to four points, treatment was possible in 70.2% (66/94) patients. Addition of extravasation at computed tomography to a NOBLADS score of ≧ 4 points allowed treatment of all patients (24/24).ConclusionsSeverity scoring in acute lower gastrointestinal bleeding was effective for predicting SRH identification in CDB. We suggest that combination of these scorings and CT findings could offer a new therapeutic strategy.

Project description:Background and study aimsDirect or indirect clipping and endoscopic band ligation (EBL) are widely used for hemostasis in patients with colonic diverticular bleeding (CDB). However, no treatment selection strategy has been established. This report describes our approach and its outcomes.Patients and methodsWe select direct clipping if the bleeding point is visible and clips could be inserted into the diverticulum. When direct clipping is not feasible, we select EBL as the second choice and indirect clipping as the third. We reviewed data from 192 patients treated with clipping or EBL for definitive CDB with stigmata of recent hemorrhage (SRH) at our hospital between March 2016 and February 2023.ResultsThe hemostatic method was clipping in 84 patients (direct, n=78; indirect, n=6) and EBL in 108. The rate of SRH with active bleeding was significantly higher in the EBL group (33.3% vs. 60.2%, p <0.001). Median hemostasis time was significantly shorter in the clipping group (9 min vs. 22 min, P <0.001). There was no significant difference in the 30-day rebleeding rate between clipping and EBL (15.5% vs. 13.0%; P =0.619). There was one case of delayed perforation post-EBL. There were no complications after clipping.ConclusionsDirect clipping when placement of clips at the bleeding point is feasible and EBL when direct clipping is not feasible is a reasonable strategy in terms of effectiveness, efficiency, and safety. Selection of hemostatic method according to the visual field of SRH and maneuverability of the endoscope allows the advantages of both methods to be realized.
