A retrospective analysis of 20-year data of the surgical management of ulcerative colitis patients in Taiwan: a study of Taiwan Society of Inflammatory Bowel Disease

Management of ulcerative colitis in Taiwan: consensus guideline of the Taiwan Society of Inflammatory Bowel Disease updated in 2023

Ulcerative colitis (UC) is a chronic inflammation of the gastrointestinal tract and is characterized by alternating periods of inflammation and remission. Although UC incidence is lower in Taiwan than in Western countries, its impact remains considerable, demanding updated guidelines for addressing local healthcare challenges and patient needs. The revised guidelines employ international standards and recent research, emphasizing practical implementation within the Taiwanese healthcare system. Since the inception of the guidelines in 2017, the Taiwan Society of Inflammatory Bowel Disease has acknowledged the need for ongoing revisions to incorporate emerging therapeutic options and evolving disease management practices. This updated guideline aims to align UC management with local contexts, ensuring comprehensive and context-specific recommendations, thereby raising the standard of care for UC patients in Taiwan. By adapting and optimizing international protocols for local relevance, these efforts seek to enhance health outcomes for patients with UC.

Minimally Invasive Surgical Approach to Toxic Colitis

BACKGROUND

We aimed to compare outcomes of surgical treatments of toxic colitis (infectious/inflammatory/ischemic) by the extent of colectomy (partial vs total colectomy) and different surgical approaches (minimally invasive surgery (MIS) vs open).

METHODS

Multivariate analysis using logistic regression was used to investigate outcomes of patients with toxic colitis who underwent emergent colectomy during 2012-2019 by surgical approach and the extent of resection using NSQIP database.

RESULTS

Overall, 2,104 adult patients underwent emergent colectomy for toxic colitis within NSQIP database during 2012-2019. Overall, 1,578 (75.4%) underwent total colectomy with colostomy, 486 (23.2%) underwent partial colectomy with colostomy, and 28 (1.3%) underwent partial colectomy with anastomosis. Overall, 198 (9.4%) of procedures were minimally invasive (MIS) with a 40.1% conversion rate to open. Thirty days mortality and morbidity of the patients were 31 and 86%, respectively. There was no significant difference in mortality of partial colectomy without anastomosis compared to total colectomy (P = .86) and partial colectomy with anastomosis (P = .64). Anastomosis was associated with 32.3% anastomosis leakage and 17.9% reoperation. MIS approach was associated with significant decrease in mortality (8.6 vs 33.3%, AOR: .35, P < .01) and morbidity (62.9 vs 87.8%, AOR: .49, P < .01) of patients.

CONCLUSION

Patients with toxic colitis undergoing surgical treatment have high mortality and morbidity. An MIS approach when possible is significantly associated with decreased morbidity and mortality of patients. There was no significant difference in outcomes seen when extending the resection in multivariate analysis. Anastomosis is associated with a high anastomosis leakage and need for reoperation risk.

Effectiveness and safety of acupuncture therapy for inflammatory bowel disease: a protocol of systematic review and meta-analysis

INTRODUCTION

Previous reviews have suggested that the effectiveness of acupuncture for inflammatory bowel disease (IBD) has not well been demonstrated due to the limited randomised controlled trials (RCTs). In recent years, the growing research on acupuncture for IBD make it possible to conduct a further systematic review and synthesise more sufficient clinical data to evaluate the effectiveness and safety of acupuncture for IBD.

METHODS AND ANALYSIS

Nine electronic databases without language restriction will be retrieved from inception to March 2021, including the Cochrane Library, MEDLINE, EMBASE, Ovid, the Allied and Complementary Medicine Database, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, the Chongqing Chinese Science and Technology Periodical Database and Wanfang Database. The RCTs on acupuncture for IBD will be included. The data screening, data extraction and the assessment of risk bias will be performed respectively by two reviewers. The quality of evidence will be evaluated by using the Grading of recommendation Assessment, Development and Evaluation application. The meta-analysis will be performed if heterogeneity analysis conducted on the RevMan software (V.5.3) is insignificant. The primary outcome was symptoms alleviation after acupuncture treatment or even in the follow-up.

ETHICS AND DISSEMINATION

Ethical approval will not be needed because data of this review are not involved in patient's information and privacy. The results will be published and diffused in a peer-reviewed journal or relative conferences.

Trends and risk factors of mortality analysis in patients with inflammatory bowel disease: a Taiwanese nationwide population-based study

Background

Inflammatory bowel disease (IBD) was emerging as a worldwide epidemic disease, and the advanced therapy changed the clinical course and possibly the outcomes. Our previous study reported a higher mortality rate from (IBD) in Taiwan than in Western countries. We proposed to analyze the trend and risk factors of mortality in order to improve the care quality of IBD patients.

Methods

This retrospective study was conducted to analyze data for January 2001 to December 2015 from a registered database, compiled by the Taiwan’s National Health Insurance.

Results

Between 2001 and 2015, a total of 3806 IBD patients [Crohn’s disease (CD): 919; ulcerative colitis (UC): 2887] were registered as having catastrophic illness, and 8.2% of these patients died during follow-up. The standardized mortality ratios (SMRs) of CD and UC were 3.72 (95% CI 3.02–4.55) and 1.44 (95% CI 1.26–1.65), respectively, from 2001 to 2015, respectively. A comparison of the periods of 2011–2015 and 2001–2005 revealed a decrease in the mortality rates from both UC and CD. Multivariate Cox proportional hazards analysis identified elderly individuals; sepsis and pneumonia were the risk factors for IBD mortality. The specific risk factors of mortality were liver cancer for UC and surgeries for CD.

Conclusion

For further decreasing IBD-related mortality in Taiwan, we need to pay special attention toward elderly individuals, infection control, cancer screening and improvement in perioperative care.

Variant Two-Stage Ileal Pouch-Anal Anastomosis: An Innovative and Effective Alternative to Standard Resection in Ulcerative Colitis

BACKGROUND

Ulcerative colitis patients have been historically treated with standard single, 2-, and 3-stage operative approaches. We perform a variant 2-stage procedure beginning with total abdominal colectomy and end ileostomy followed by completion proctectomy and ileal pouch-anal anastomosis (IPAA) without a diverting loop ileostomy. This study evaluates the effectiveness of this innovative alternative.

STUDY DESIGN

Patients with ulcerative colitis, admitted to the University of North Carolina Hospital between 2003 and 2010 for IPAA, were eligible for inclusion. The 3-year cumulative incidence of pouch leaks among patients undergoing variant 2-stage were compared with those undergoing classic 2-stage, using inverse probability-of-treatment weighted Kaplan- Meier survival curves, and 95% CIs were estimated using nonparametric bootstrapping.

RESULTS

There were 248 patients who underwent IPAA; 139 (56.1%) underwent classic 2-stage and 109 (43.9%) underwent variant 2-stage. After standardization, there was no significant difference in the 3-year cumulative incidence of pouch leaks between patients undergoing variant 2-stage, compared with the standard single- or 2-stage procedure (risk difference 0.01; 95% CI -0.08, 0.15). At the time of the first surgical procedure, patients undergoing a variant 2-stage were more likely to have lower BMIs (median 22.5 kg/m² vs 26.7 kg/m²; p < 0.0001), an urgent/emergent procedure (56.9% vs 0.0%; p < 0.0001), biologic use within 2 weeks of surgery (32.1% vs 17.5%; p = 0.003), and high dose steroid use (60.4% vs 16.7%; p ≤ 0.0001).

CONCLUSIONS

Variant 2-stage IPAA is a safe and effective operative approach with comparable outcomes in a more acute population based on BMI, steroid use, and urgency of operation.
