Association Between Sense of Coherence, Disease-Specific Symptoms, and Health-Related Quality of Life Among Japanese Patients with Ulcerative Colitis: A Cross-Sectional Study.

INTRODUCTION: We examined the associations among disease-related symptoms, health-related quality of life (HRQOL), and sense of coherence (SOC) in Japanese patients with ulcerative colitis (UC). METHODS: This cross-sectional survey involved patients and physicians at 23 hospitals specializing in UC treatment in Japan (December 2019-December 2020). Multiple linear regression analysis was performed using scores on the Mental Health and General Health subscales of the Medical Outcomes Study 36-Item Short-Form Health Survey as outcomes and SOC as the main independent variable. Scores on the Inflammatory Bowel Disease Questionnaire (IBDQ) and Fecal Incontinence Quality of Life Scale (FIQL) were used to measure the effect of disease-related symptoms. The moderating effect of symptoms on the association between HRQOL and SOC was also tested. RESULTS: SOC was positively and independently associated with HRQOL (Mental Health: ß = 0.43, 95% confidence interval [CI] = 0.24-0.61, P < 0.001; General Health: ß = 0.41, 95% CI = 0.23-0.59, P < 0.001). The association of SOC with Mental Health scores did not differ by symptoms, whereas its association with General Health was attenuated by symptoms (interaction term of IBDQ by SOC: ß = -0.0082, 95% CI = -0.017 to 0.00064, P = 0.07; that of FIQL by SOC: ß = -0.0052, 95% CI = -0.011 to 0.0010, P = 0.10). CONCLUSIONS: SOC affected mental health independently, and its protective association with general health perception was affected by symptoms. Further research is required to determine the most effective use of SOC in interventions to improve HRQOL in patients with UC.

[A case of ulcerative colitis complicated by disseminated intravascular coagulation that improved markedly after surgery].

A 57-year-old man presenting with severe ulcerative colitis (UC) complicated by disseminated intravascular coagulation (DIC) was referred to our hospital. Since it was difficult to improve DIC immediately with any medical treatment, total proctocolectomy, ileoanal canal anastomosis, and ileostomy were performed on the patient. Soon after the surgery, his platelet count and coagulability improved, and he recovered from DIC. Thus, when the cause of DIC is probably UC itself, and medical treatment has limited efficacy in improving the DIC, surgery should be performed as soon as possible to eliminate the cause of DIC, considering the general condition of the patient.

Endoscopic Lesions of Postoperative Anastomotic Area in Patients With Crohn's Disease in the Biologic Era: A Japanese Multi-Centre Nationwide Cohort Study.

BACKGROUND AND AIMS: Many patients have endoscopic evidence of recurrent Crohn's disease [CD] at 1 year after intestinal resection. These lesions predict future clinical recurrence. We endoscopically evaluated postoperative anastomotic lesions in CD patients from a large cohort of postoperative CD patients. METHODS: We retrospectively enrolled CD patients who underwent surgical resection between 2008 and 2013 at 19 inflammatory bowel disease [IBD]-specialist institutions. The initial analyses included patients who underwent ileocolonoscopy ~1 year after intestinal resection. Follow-up analyses assessed any changes in the endoscopic findings over time. We evaluated the postoperative endoscopic findings, which were classified into four categories [no lesion, mild, intermediate, severe] at the sites of the anastomotic line and peri-anastomosis. RESULTS: In total, 267 CD patients underwent postoperative ileocolonoscopy. Postoperative anastomotic lesions were widely detected in index ileocolonoscopy [61.0%] and were more frequently detected in follow-up ileocolonoscopy [74.9%]. Endoscopic severity also increased. Patients with intermediate or severe peri-anastomotic or anastomotic line lesions at the index ileocolonoscopy required significantly more interventions, including endoscopic dilatation or surgery, than patients with mild lesions or no lesions. CONCLUSIONS: Frequent anastomotic lesions were observed at the postoperative index ileocolonoscopy. These gradually increased for subsequent ileocolonoscopy, even in the biologic era. Regarding lesions on the anastomotic line, intermediate lesions on the anastomotic line [e.g. irregular or deep ulcers] might be considered recurrent disease, and mild lesions [e.g. linear superficial ulcers] might be considered non-recurrent disease. Prospective studies are needed to resolve this issue, including treatment enhancement.

Impact of the body mass index on the retention of the anorectal mucosa after double-stapled ileal pouch-anal anastomosis for ulcerative colitis.

BACKGROUND: Double-stapled ileal pouch-anal anastomosis (DS-IPAA) is easy to construct and has a good functional outcome in patients with ulcerative colitis (UC). However, retention of the anorectal mucosa may lead to a subsequent risk of inflammation and neoplasia. This study aimed to identify factors associated with the retention of a large amount of anorectal mucosa after DS-IPAA. METHODS: The medical records of 163 patients who had undergone one-stage total proctocolectomy and DS-IPAA for UC between 2007 and 2020 were retrospectively reviewed. The patients were divided into two groups according to the length of the retained mucosa. The high anastomosis group was defined as having a retained mucosal length of ≥ 30 mm in the anterior or posterior wall. Clinical factors were compared between the high and low anastomosis groups. RESULTS: The high anastomosis group showed a significantly higher body mass index (BMI) (high vs. low: 23.2 vs. 19.0), longer operation time (304 vs. 263) and greater blood loss (357 vs. 240). In the multivariate analysis, high BMI was the only factor significantly associated with high anastomosis (odds ratio 1.32). There was a positive correlation between BMI and the length of the retained mucosa. CONCLUSIONS: In DS-IPAA, BMI showed the strongest association with the retention of a large amount of the anorectal mucosa. In high BMI patients, although the risk of inability of anastomosis is little than that of IPAA with mucosectomy, the possible retention of a large amount of mucosa should be considered.

[Surgical treatment for ulcerative colitis in patients over 70 years of age].

The clinical course of 104 patients with ulcerative colitis who underwent primary surgery at ≥70 years was retrospectively examined. Pre- and postoperative patient conditions determined the choice of surgical procedure. Approximately half of the patients underwent restorative proctocolectomy, resulting in relatively good defecation function. In addition, the long-term outcomes of patients who underwent permanent ileostomy were favorable. However, the postoperative complication and mortality rates were high in all patients, including those with low preoperative performance status due to long-term hospitalization. In this patient population, surgery should be conducted before decreased performance status due to long-term hospitalization.

Postoperative results and complications of fecal diversion for anorectal Crohn's disease.

PURPOSE: Fecal diversion is a less-invasive technique that can alleviate symptoms in patients with refractory anorectal Crohn's disease. However, complications, including recurrence of residual anorectal Crohn's disease, may develop. We aimed to evaluate the postoperative results and complications associated with fecal diversion in patients with refractory anorectal Crohn's disease. METHODS: We enrolled 1218 Crohn's disease patients who underwent laparotomy at our institute. We retrospectively analyzed the clinical features of 174 patients who underwent fecal diversion for refractory anorectal Crohn's disease, complications of the diverted colorectum, and the incidence and risk factors for proctectomy after fecal diversion. RESULTS: After fecal diversion, 74% of patients showed improved symptoms. However, bowel continuity restoration was successful in four patients (2.2%), and anorectal Crohn's disease recurred in all patients. Seventeen patients developed cancer with a poor prognosis. The rate of conversion to proctectomy after fecal diversion was 41.3%, and the risk factors included rectal involvement (p = 0.02), loop-type stoma (p < 0.01), and the absence of treatment with biologics after fecal diversion (p = 0.03). CONCLUSION: Fecal diversion for refractory anorectal Crohn's disease can improve clinical symptoms. Patients with rectal involvement or loop-type stoma have a greater risk of requiring proctectomy following fecal diversion. The administration of biologic may decrease the rate of proctectomy.

Efficacy, safety, and pharmacokinetics of teduglutide in adult Japanese patients with short bowel syndrome and intestinal failure: two phase III studies with an extension.

PURPOSE: The short- and long-term efficacy, safety, and pharmacokinetics of teduglutide were analyzed in adult Japanese patients with short bowel syndrome and intestinal failure (SBS-IF). METHODS: Patients received teduglutide 0.05 mg/kg/day in clinical trials (TED-C14-004, SHP633-306, and extension SHP633-307). Data were analyzed at 24 weeks and an interim data cut-off of 4.5 years. RESULTS: The parenteral support (PS) volume decreased by ≥ 20% for 9/18 patients at 24 weeks and in all 11 patients by data cut-off in SHP633-307. The mean (standard deviation) PS volume decreased from baseline at 24 weeks in TED-C14-004 (-30.1 ± 25.9%) and SHP633-306 (-25.6 ± 25.5%), and at data cut-off in SHP633-307 (-57.08 ± 28.49%). Teduglutide was absorbed quickly. The adverse events were consistent with the underlying disease and known adverse drug reactions. Anti-teduglutide antibody titers declined with long-term treatment. CONCLUSIONS: In Japanese adults with SBS-IF, teduglutide treatment was associated with clinically meaningful reductions in PS requirements, similar to findings in prior international studies. No new safety concerns specific to the Japanese SBS-IF patient population were identified with short- or long-term teduglutide treatment. Anti-teduglutide antibody titers disappeared in most Japanese adults with long-term treatment. These results constitute the longest evaluation of teduglutide treatment within clinical trials reported to date.

Management of pouch neoplasia: consensus guidelines from the International Ileal Pouch Consortium.

Surveillance pouchoscopy is recommended for patients with restorative proctocolectomy with ileal pouch-anal anastomosis in ulcerative colitis or familial adenomatous polyposis, with the surveillance interval depending on the risk of neoplasia. Neoplasia in patients with ileal pouches mainly have a glandular source and less often are of squamous cell origin. Various grades of neoplasia can occur in the prepouch ileum, pouch body, rectal cuff, anal transition zone, anus, or perianal skin. The main treatment modalities are endoscopic polypectomy, endoscopic ablation, endoscopic mucosal resection, endoscopic submucosal dissection, surgical local excision, surgical circumferential resection and re-anastomosis, and pouch excision. The choice of the treatment modality is determined by the grade, location, size, and features of neoplastic lesions, along with patients' risk of neoplasia and comorbidities, and local endoscopic and surgical expertise.

Management of Pouch Neoplasia.

BACKGROUND: Pouch neoplasia occurs following ileal pouch-anal anastomosis, with or without mucosectomy in ulcerative colitis and familiar adenomatous polyposis. OBJECTIVES: This study aimed to review available literature and make recommendations regarding pouch neoplasia. DATA SOURCES: Data were collected from specialty hospitals, and a literature review was conducted due to the lack of published large-scale studies. Recommendations for treatment were made based on the literature review and expert opinions. STUDY SELECTION: Large-scale studies of pouch neoplasia were selected. INTERVENTION: The intervention was studies with details of pouch neoplasia. MAIN OUTCOME MEASURES: We aimed to identify the management modalities for pouch neoplasia based on the type. RESULTS: Pouch neoplasia can occur in each component of the pouch-afferent limb, pouch body, cuff, and anal transitional zone. In patients with ulcerative colitis, pouch neoplasia is treated because colitis-associated neoplasia comprises a multifocal lesion, which most commonly involves the cuff and anal transitional zone. Close surveillance or endoscopic complete resection is optimal for low-grade dysplasia. For adenocarcinoma, high-grade dysplasia, and low-grade dysplasia with difficult complete resection, pouch excision is recommended. In familiar adenomatous polyposis patients with adenomas of the afferent limb or pouch body, endoscopic resection is optimal. Endoscopic resection is feasible for discrete adenoma in the cuff and anal transitional zone, and surgical excision is optimal for laterally spreading, extensive, large, or flat adenoma. For adenocarcinomas involving any component, pouch excision is recommended. LIMITATIONS: Published large-scale studies were lacking because of disease rarity. CONCLUSION: Pouch neoplasia occurs in each pouch component. In patients with ulcerative colitis, pouch excision is recommended for adenocarcinomas and high-grade dysplasia, whereas endoscopic intervention may be preferable to low-grade dysplasia. In familiar adenomatous polyposis patients, pouch excision is necessary for adenocarcinoma, and endoscopic resection or excisional surgery is optimal for adenoma.

A review on the current status and definitions of activity indices in inflammatory bowel disease: how to use indices for precise evaluation.

Many clinical trials have been conducted for inflammatory bowel disease (IBD), so various clinical indices (CIs) and endoscopic indices (EIs) have also been evaluated. However, recently, with the progress of IBD management, review of established indices from previous studies, and establishment of new indices, the landscape of the use of indices in clinical trials have changed. We investigated the number and frequency of the indices adapted in recent clinical trials for ulcerative colitis (CI and EI) and Crohn's disease (CI, EI, index related to magnetic resonance imaging, index for evaluating patient-reported outcomes, and health-related quality of life). Based on the results, we selected representative indices and further reviewed their content and characteristics. Moreover, various definitions, including clinical and endoscopic response or remission, have been described by means of representative indices in clinical trials.

Postoperative complications, bowel function, and prognosis in restorative proctocolectomy for ulcerative colitis-a single-center observational study of 320 patients.

PURPOSE: To determine the selection criteria, postoperative complications, bowel function, and prognosis of stapled ileal pouch-anal anastomosis (IPAA) and hand-sewn IPAA for ulcerative colitis (UC). METHODS: We defined our surgical indications and strategy, and compared the postoperative complications, bowel function, and prognoses between patients who underwent stapled and hand-sewn IPAA for UC at the Yokohama City University Medical Center between 2004 and 2017. RESULTS: Among 320 patients enrolled, 298 patients underwent stapled IPAA while 22 underwent hand-sewn IPAA. There was no significant difference in the postoperative complications between the two groups. Regarding postoperative bowel function, stapled IPAA caused significantly less soiling (stapled vs hand-sewn: 9.1% vs 41.0%, odds ratio (OR) = 0.14, p < 0.0002), spotting (stapled vs hand-sewn: 23.2% vs 63.6%, OR = 0.17, p < 0.0001), and difficulty in distinguishing feces from flatus (stapled vs hand-sewn: 39.9% vs 63.6%, OR = 0.36, p < 0.026). No postoperative neoplasia was observed at the final follow-up in all patients. CONCLUSION: In this study, there was no clear difference in the postoperative complications between stapled and hand-sewn IPAA, but stapled IPAA resulted in better postoperative bowel function. Postoperative oncogenesis from the residual mucosa is rare. However, future cancer risk remains; thus, careful follow-up is required.

Treatment of pouchitis, Crohn's disease, cuffitis, and other inflammatory disorders of the pouch: consensus guidelines from the International Ileal Pouch Consortium.

Pouchitis, Crohn's disease of the pouch, cuffitis, polyps, and extraintestinal manifestations of inflammatory bowel disease are common inflammatory disorders of the ileal pouch. Acute pouchitis is treated with oral antibiotics and chronic pouchitis often requires anti-inflammatory therapy, including the use of biologics. Aetiological factors for secondary pouchitis should be evaluated and managed accordingly. Crohn's disease of the pouch is usually treated with biologics and its stricturing and fistulising complications can be treated with endoscopy or surgery. The underlying cause of cuffitis determines treatment strategies. Endoscopic polypectomy is recommended for large, symptomatic inflammatory polyps and polyps in the cuff. The management principles of extraintestinal manifestations of inflammatory bowel disease in patients with pouches are similar to those in patients without pouches.

[A case of a patient with Crohn's disease who had vaginal delivery after abdominoperineal resection for severe anorectal complications].

We report the case of a young female patient with Crohn's disease case who had vaginal delivery after abdominoperineal resection for severe perianal disease. The patient had Crohn's disease with anorectal complications for 13 years and underwent abdominoperineal resection for anorectal stenosis, complex anal fistula, and rectovaginal fistula in her early twenties. Seven years later, she got pregnant and gave birth to a healthy boy by vaginal delivery. No recurrence of Crohn's disease was observed during the perinatal period. There is no curative treatment for severe anorectal complications, which may be necessary for young patients to undergo abdominoperineal resection. Further studies are needed to determine the effects of Crohn's disease with anorectal complications on pregnancy and childbirth in affected patients.

[Pregnancy and delivery in patients with Crohn's disease who had a history of abdominal surgery].

OBJECTIVE: A few studies have focused on pregnancy and childbirth in patients with Crohn's disease (CD) who had a history of abdominal surgery. The objective of this study is to analyze the problems of pregnant patients with CD with a history of abdominal surgery. METHODS: The rates of pregnancy-related complications and adverse birth outcomes were retrospectively analyzed in 29 patients with CD (45 pregnancies) with previous intestinal surgery. RESULTS: In this study, the following outcomes were observed:normal births occurred in 55.6% of the pregnancies, preterm births in 13.3%, and spontaneous abortions in 20.0%. The vaginal birth and cesarean section rates were 45.7% and 40.0%, respectively. The rate of low-birth weight infants was 14.3%. CONCLUSION: Overall, patients with CD with previous abdominal surgery can conceive and give birth. However, care needs to be taken to avoid preterm birth, spontaneous abortion, low birth weight, and cesarean delivery.

Diagnosis and classification of ileal pouch disorders: consensus guidelines from the International Ileal Pouch Consortium.

Restorative proctocolectomy with ileal pouch-anal anastomosis is an option for most patients with ulcerative colitis or familial adenomatous polyposis who require colectomy. Although the construction of an ileal pouch substantially improves patients' health-related quality of life, the surgery is, directly or indirectly, associated with various structural, inflammatory, and functional adverse sequelae. Furthermore, the surgical procedure does not completely abolish the risk for neoplasia. Patients with ileal pouches often present with extraintestinal, systemic inflammatory conditions. The International Ileal Pouch Consortium was established to create this consensus document on the diagnosis and classification of ileal pouch disorders using available evidence and the panellists' expertise. In a given individual, the condition of the pouch can change over time. Therefore, close monitoring of the activity and progression of the disease is essential to make accurate modifications in the diagnosis and classification in a timely manner.

Subtotal colectomy for refractory ulcerative colitis with COVID-19 infection; a first case report in Japan.

We report a 60-year-old male who was transferred to our hospital for the operation because of refractory ulcerative colitis (UC). He was diagnosed to be infected with COVID-19 for SARS-CoV-2 PCR test positive at the time of transfer. We determined emergency operation because his general condition was poor such as malnutrition and ADL decline due to exacerbation of UC and air embolization by central venous catheter removal. He underwent subtotal colectomy with a sigmoid mucous fistula and ileostomy. He was well postoperatively. This is a first case report in Japan who underwent an operation for UC with COVID-19 infection.

[Preoperative diagnosis of small intestinal cancer associated with Crohn's disease: a case report].

The patient was a 46-year-old woman with a history of Crohn's disease for several years. At 45 years of age, a colonoscopy was performed, and a protruding lesion in the terminal ileum was detected. Pathological analysis of a biopsy specimen noted high suspicion for a well differentiated adenocarcinoma. The patient underwent ileocecal resection, and histological examination of the specimen revealed that infiltration of the well differentiated adenocarcinoma was limited to the mucosa. To the best of our knowledge, this is the first known case of early small intestinal cancer associated with Crohn's disease in Japan. Both endoscopy and a biopsy of any protruding lesions may be useful for making a preoperative diagnosis of small intestinal cancer associated with Crohn's disease.

Postoperative Survival in Colitis-associated Colorectal Cancer With Ulcerative Colitis in Japan: A Multicenter Analysis.

BACKGROUND/AIM: The aim of the study was to analyze the postoperative survival of colitis-associated colorectal cancer (CAC) with ulcerative colitis (UC), and the risk factors affecting it. PATIENTS AND METHODS: A questionnaire including postoperative survival was sent to 88 hospitals that reported CAC patients in the literature up until January, 2006 and to members of the Research Group of Intractable Inflammatory Bowel Disease. RESULTS: The 5-year postoperative overall survival (OS) of 170 CAC patients was 74.2% which was similar to sporadic colorectal cancer in Japan (72.1%). Pathologic TNM stage, histological type, type of surgical procedure (proctocolectomy, segmental resection), and preoperative cancer surveillance were statistically significant factors for OS. By Cox regression analysis, pathologic TNM stage and proctocolectomy were statistically significant prognostic factors for OS. CONCLUSION: In CAC with UC, the postoperative OS was similar to sporadic colorectal cancer. Pathologic TNM stage and proctocolectomy were confirmed as important prognostic factors.

Clinicopathological and prognostic evaluations of anorectal cancer after fecal diversion for patients with Crohn's disease.

PURPOSE: Colorectum diversion with a proximal stoma is often the preferred surgical approach in patients with Crohn's disease-related anorectal lesions or refractory colitis. To date, few studies have assessed the incidence and prognosis of cancer in the diverted anorectal segments. This study aimed to evaluate the clinical characteristics and prognosis of anorectal cancer associated with Crohn's disease following fecal diversion. METHODS: This was a retrospective study based on medical records of patients diagnosed with Crohn's disease between 1999 and 2020. It was conducted at Yokohama Municipal Citizen's Hospital. Patients diagnosed with anorectal cancer following fecal diversion were identified, and their prognosis was the primary outcome measure. RESULTS: Among 1615 patients, 232 patients (14%) underwent colorectum diversion. Of those 232 patients, 11 were diagnosed with anorectal cancer following fecal diversion, ten were diagnosed with advanced cancer, 10 underwent abdominoperineal resection, and eight died. 1 could not undergo resection due to multiple lung metastasis and died. The overall five-year survival rate in patients diagnosed with anorectal cancer following fecal diversion was 20%. CONCLUSION: Crohn's disease-associated anorectal cancer following fecal diversion was challenging to diagnose early, and patients had a poor prognosis even after curative resection. Early abdominoperineal resection may be considered for patients with Crohn's disease who cannot benefit from cancer screening and surveillance due to difficulty accessing the anorectal stricture via endoscopy.

Perioperative Venous Thromboembolism in Ulcerative Colitis: A Multicenter Prospective Study in Japan.

Background: Recently, the prevalence of venous thromboembolism (VTE) in Asian patients with inflammatory bowel disease (IBD) is gradually increasing. IBD surgery is a well-recognized risk factor for VTE. However, there are no prospective studies about VTE after surgery for ulcerative colitis (UC) in Asia. This multicenter prospective study aimed to clarify the prevalence and risk factors for perioperative VTE in UC surgery in Japan. Methods: A total of 134 patients with UC were included from January 1, 2013 to December 31, 2014. Preoperative screening was performed in all patients. In the perioperative period, standard VTE prophylaxis based on risk assessment was administered. The prevalence of pre- and postoperative VTE, its risk factors, and mortality rates were investigated. Results: Perioperative deep vein thrombosis and pulmonary embolism were diagnosed in 15 (11.1%) and 1 patient (0.7%), respectively. All patients were asymptomatic. No surgery-related deaths were found (mortality rate 0%). Seven patients (5.2%) were diagnosed, and 8 (6.4%) during postoperative follow-up by ultrasonography or computed tomography. Forty-seven percent of VTE cases was developed preoperatively. A preoperative hospital length stay of over 5 days was a significant risk factor [P = 0.04; odds ratio: 8.26 (1.06-64.60)] for preoperative VTE. Postoperative deep vein thrombosis occurred in 8 of the 127 patients (6.4%). Six out of these 8 (75.0%) occurred after postoperative day 14. Perioperative blood transfusion was a significant risk factor [P = 0.04; odds ratio: 8.26 (1.06-64.60)] for postoperative VTE. Conclusion: A VTE-conscious perioperative management is as necessary in Asia as in Western countries.
