OBJECTIVE: To examine the outcome of endoscopic retrograde cholangiopancreatography (ERCP) in the management of common bile duct (CBD) stones. DESIGN: A retrospective review of 100 consecutive ERCPs performed for CBD stones. RESULTS: 100 ERCPs were performed on 84 patients with a median cohort age of 77. Completion in this cohort, as defined by duct clearance, was achieved in 65% of cases. Completion rates fell rapidly after two ERCPs. 33% of the cohort had small stones <10 mm, and 67% had stones >10 mm. Size, but not number of stones, affected the completion rate and frequency of complications (16%). Presence of periampullary diverticulum did not affect completion or complication rates. MR cholangiopancreatography (MRCP) had a 90% sensitivity for detecting CBD stones compared with 56% for CT. DISCUSSION AND CONCLUSIONS: ERCP remains a high-risk procedure with a significant complication rate when performed to deal with CBD stones. MRCP should be the second choice of investigation for CBD stones. This cohort had an unusually high number of larger stones at ERCP of 67% compared with other published UK cohorts of 8%, and this was reflected in the completion and complication rate.

Patient-led variable dosing with balsalazide as long-term therapy for maintenance in ulcerative colitis: a 3-year prospective observational study.

BACKGROUND: The patient-centred approach is new to the management of ulcerative colitis. To date, it has only been shown to be successful in a short-term study. AIM: To assess the feasibility, safety and efficacy of patient-led dosing using balsalazide in the long-term treatment of ulcerative colitis. METHODS: This was a 3-year, two-cohort, multi-centre study: one cohort was in stable remission (52 patients) and the other was newly in remission (76 patients) from ulcerative colitis. Two 750-mg balsalazide capsules were given twice daily for maintenance, increased by 750-mg increments to a maximum of 6 g for up to 7 days depending on symptom severity. Clinical assessments were made every 12-14 weeks; laboratory assessments were made every 6 months. RESULTS: The average median daily dose of balsalazide was 3 g (range, 1.5-6 g). In the cohort with stable remission, 23 patients (44%) had relapsed by 3 years [median time to relapse, > 1095 days (36 months)]. In the cohort newly in remission, these values were 45 patients (59%) and 656 days (22 months), respectively. In the cohort with stable remission, the time since last relapse was significantly associated with relapse during the first year of treatment (P < 0.033). CONCLUSIONS: Long-term, patient-led, maintenance treatment with balsalazide is well tolerated with a good safety profile and is effective for patients with ulcerative colitis.

A double-blind comparison of balsalazide, 6.75 g daily, and sulfasalazine, 3 g daily, in patients with newly diagnosed or relapsed active ulcerative colitis.

BACKGROUND: Sulfasalazine is well established in the treatment of active ulcerative colitis. Intolerance to sulfasalazine, however, is a common problem. Balsalazide has been designed to deliver 5-aminosalicylic acid to the colon without the poor tolerability of sulfasalazine. AIM: To compare the safety and efficacy of balsalazide, 6.75 g daily, with sulfasalazine, 3 g daily, in the treatment of active ulcerative colitis of all grades of severity. METHODS: Balsalazide and sulfasalazine were compared in a multicentre, double-blind, parallel group study over 12 weeks. Patients were stratified for disease severity and topical and/or oral steroids were co-administered where clinically necessary. RESULTS: Fifty-seven patients were randomized: 28 to receive balsalazide and 29 to receive sulfasalazine. Significantly fewer patients withdrew from the balsalazide group due to adverse events (2/28 vs. 9/29, P=0.041). These data confirm that balsalazide is better tolerated than sulfasalazine. In patients able to tolerate the treatment, similar improvements were recorded in clinical, sigmoidoscopic and histological assessments in both treatment groups. CONCLUSIONS: This study confirms the better tolerability of balsalazide compared to sulfasalazine, and supports the use of balsalazide in ulcerative colitis of all grades of severity.
