Abstract PDF: Adenocarcinoma is a common histological type of ulcerative colitis-associated cancer (UCAC), whereas neuroendocrine carcinoma (NEC) is extremely rare. UCAC is generally diagnosed at an advanced stage, even with regular surveillance colonoscopy. A 41-year-old man with a 17-year history of UC began receiving surveillance colonoscopy at the age of 37 years; 2 years later, dysplasia was detected in the sigmoid colon, and he underwent colonoscopy every 3 to 6 months. Approximately 1.5 years thereafter, a flat adenocarcinoma lesion occurred in the rectum. Flat lesions with high-grade dysplasia were found in the sigmoid colon and surrounding area. The patient underwent laparoscopic total proctocolectomy and ileal pouch-anal anastomosis with ileostomy. Adenocarcinoma was diagnosed in the sigmoid colon and NEC in the rectum. One year postoperation, recurrence or metastasis was not evident. Regular surveillance colonoscopy is important in patients with long-term UC. A histological examination of UCAC might demonstrate NEC.

Purpose
The albumin to globulin ratio (AGR) is a recognized chronic inflammation marker. No evidence regarding the relationship between AGR level and ulcerative colitis (UC) exists. The aim of this study was to evaluate the association between AGR and clinical outcomes among Japanese subjects with UC.
Methods
The study subjects consisted of 273 Japanese individuals with UC. AGR was divided into 4 categories (low, moderate, high, and very high). The definition of complete mucosal healing (MH) was based on the Mayo endoscopic subscore of 0. Clinical remission (CR) was defined as no rectal bleeding and no abnormally high stool frequency (<3 times per day).
Results
The percentage of MH was 26.4%. High AGR and very high AGR were significantly positively correlated with CR (adjusted odds ratio [OR], 5.85; 95% confidence interval [CI], 2.52–14.18 and adjusted OR, 4.97; 95% CI, 2.14–12.04) and complete MH (adjusted OR, 4.03; 95% CI, 1.56–11.51 and adjusted OR, 5.22; 95% CI, 1.97–14.89), respectively after adjustment for confounding factors (P for trend=0.001). Only in the low C-reactive protein (CRP) group (≤0.1 mg/dL), very high AGR was significantly positively correlated with complete MH but not CR (adjusted OR, 4.38; 95% CI, 1.06–21.77; P for trend=0.017). In the high CRP group, no correlation between AGR and complete MH was found.
Conclusion
Among Japanese patients with UC, AGR may be independently positively correlated with complete MH. In particular, among UC patients with low CRP, AGR might be a useful complementary marker for complete MH.

Abstract PDF

Purpose
Ulcerative colitis (UC) is known to have an association with the increased risk of colorectal cancer (CRC), and UC-associated CRC does not follow the typical progress pattern of adenoma-carcinoma. The aim of this study is to investigate molecular characteristics of UC-associated CRC and further our understanding of the association between UC and CRC.
Methods
From 5 patients with UC-associated CRC, matched normal, dysplasia, and tumor specimens were obtained from formalin-fixed paraffin-embedded (FFPE) samples for analysis. Genomic DNA was extracted and whole exome sequencing was conducted to identify somatic variations in dysplasia and tumor samples. Statistical analysis was performed to identify somatic variations with significantly higher frequencies in dysplasia-initiated tumors, and their relevant functions were investigated.
Results
Total of 104 tumor mutation genes were identified with higher mutation frequencies in dysplasia-initiated tumors. Four of the 5 dysplasia-initiated tumors (80.0%) have TP53 mutations with frequent stop-gain mutations that were originated from matched dysplasia. APC and KRAS are known to be frequently mutated in general CRC, while none of the 5 patients have APC or KRAS mutation in their dysplasia and tumor samples. Glycoproteins including mucins were also frequently mutated in dysplasia-initiated tumors.
Conclusion
UC-associated CRC tumors have distinct mutational characteristics compared to typical adenoma-carcinoma tumors and may have different cancer-driving molecular mechanisms that are initiated from earlier dysplasia status.

Abstract PDF

Purpose
We report outcomes and evaluate patient factors and the impact of surgical evolution on outcomes in consecutive ulcerative colitis patients who had restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) at an Australian institution over 26 years.
Methods
Data including clinical characteristics, preoperative medical therapy, and surgical outcomes were collected. We divided eligible patients into 3 period arms (period 1, 1990 to 1999; period 2, 2000 to 2009; period 3, 2010 to 2016). Outcomes of interest were IPAA leak and pouch failure.
Results
A total of 212 patients were included. Median follow-up was 50 (interquartile range, 17 to 120) months. Rates of early and late complications were 34.9% and 52.0%, respectively. Early complications included wound infection (9.4%), pelvic sepsis (8.0%), and small bowel obstruction (6.6%) while late complications included small bowel obstruction (18.9%), anal stenosis (16.8%), and pouch fistula (13.3%). Overall, IPAA leak rate was 6.1% and pouch failure rate was 4.8%. Eighty-three patients (42.3%) experienced pouchitis. Over time, we observed an increase in patient exposure to thiopurine (P=0.0025), cyclosporin (P=0.0002), and anti-tumor necrosis factor (P<0.00001) coupled with a shift to laparoscopic technique (P<0.00001), stapled IPAA (P<0.00001), J pouch configuration (P<0.00001), a modified 2-stage procedure (P=0.00012), and a decline in defunctioning ileostomy rate at time of IPAA (P=0.00002). Apart from pouchitis, there was no significant difference in surgical and chronic inflammatory pouch outcomes with time.
Conclusion
Despite greater patient exposure to immunomodulatory and biologic therapy before surgery coupled with a significant change in surgical techniques, surgical and chronic inflammatory pouch outcome rates have remained stable.

Abstract PDF

Purpose
This study aimed to compare the short-term outcomes of the open and laparoscopic approaches to 2-stage restorative proctocolectomy (RPC) for Korean patients with ulcerative colitis (UC).
Methods
We retrospectively analyzed the medical records of 73 patients with UC who underwent elective RPC between 2009 and 2016. Patient characteristics, operative details, and postoperative complications within 30 days were compared between the open and laparoscopic groups.
Results
There were 26 cases (36%) in the laparoscopic group, which had a lower mean body mass index (P = 0.025), faster mean time to recovery of bowel function (P = 0.004), less intraoperative blood loss (P = 0.004), and less pain on the first and seventh postoperative days (P = 0.029 and P = 0.027, respectively) compared to open group. There were no deaths, and the overall complication rate was 43.8%. There was no between-group difference in the overall complication rate; however, postoperative ileus was more frequent in the open group (27.7% vs. 7.7%, P = 0.043). Current smoking (odds ratio [OR], 44.4; P = 0.003) and open surgery (OR, 5.4; P = 0.014) were the independent risk factors for postoperative complications after RPC.
Conclusion
Laparoscopic RPC was associated with acceptable morbidity and faster recovery than the open approach. The laparoscopic approach is a feasible and safe option for surgical treatment for UC in selective cases.

Abstract PDF

Purpose
Inflammatory bowel disease (IBD) in Korea has been increasing in recent years, but accurate statistics about operations for IBD are lacking. The purpose of this study was to investigate the trends and current status of IBD surgeries in Korea.
Methods
Using a national database from the Korea Health Insurance Review and Assessment Service, we analyzed data from patients who underwent surgery for Crohn disease and ulcerative colitis from January 2009 to October 2016. Results: The mean number of patients who underwent surgery for Crohn disease was 791.8 per year. Colorectal surgery, small bowel surgery, and anal surgery were performed fairly often (31.2%, 29.4%, 39.4%, respectively), and laparoscopic surgery continued to increase, recently exceeding 30%. About 50% of Crohn patients used biologics before and after surgery, and those patients also underwent a relatively high rate of anal surgeries (44.2%). The mean number of patients who underwent surgery for ulcerative colitis was 247.6 per year. Colorectal surgery accounted for more than half of all operations, and laparoscopic surgery has been increasing rapidly, having been performed in about 60% of patients in recent years. The incidence of colorectal cancer in patients with ulcerative colitis was very high and increased rapidly during the study period, reaching about 80%.
Conclusion
The number of patients undergoing laparoscopic surgery for IBD in Korea has increased significantly. Biologics are actively used by patients with Crohn disease, with a high proportion of anal surgeries required. Many of the surgical indications for ulcerative colitis have shifted into colorectal cancer.

Abstract PDF

Purpose
While perianal disease (PAD) is a characteristic of patients with Crohn disease, it has been overlooked in patients with ulcerative colitis (UC). Thus, our study aimed to analyze the incidence and the clinical features of PAD in patients with UC.
Methods
We reviewed the data on 944 patients with an initial diagnosis of UC from October 2003 to October 2015. PAD was categorized as hemorrhoids, anal fissures, abscesses, and fistulae after anoscopic examination by experienced proctologists. Data on patients’ demographics, incidence and types of PAD, medications, surgical therapies, and clinical course were analyzed.
Results
The median follow-up period was 58 months (range, 12–142 months). Of the 944 UC patients, the cumulative incidence rates of PAD were 8.1% and 16.0% at 5 and 10 years, respectively. The incidence rates of bleeding hemorrhoids, anal fissures, abscesses, and fistulae at 10 years were 6.7%, 5.3%, 2.6%, and 3.4%, respectively. The cumulative incidence rates of perianal sepsis (abscess or fistula) were 2.2% and 4.5% at 5 and 10 years, respectively. In the multivariate analyses, male sex (risk ratio [RR], 4.6; 95% confidence interval [CI], 1.7–12.5) and extensive disease (RR, 4.2; 95% CI, 1.6–10.9) were significantly associated with the development of perianal sepsis.
Conclusion
Although the clinical course of PAD in patients with UC is not serious, in clinical practice, PAD is not rare in such patients. Therefore, careful examination and appropriate management for PAD is needed if the quality of life for patients with UC is to be improved.

Purpose
Small bowel obstruction (SBO) remains a common complication after pelvic or abdominal surgery. However, the risk factors for SBO in ulcerative colitis (UC) surgery are not well known. The aim of the present study was to clarify the risk factors associated with SBO after ileal pouch-anal anastomosis (IPAA) with a loop ileostomy for patients with UC.
Methods
The medical records of 96 patients who underwent IPAA for UC between 1999 and 2011 were reviewed. SBO was confirmed based on the presence of clinical symptoms and radiographic findings. The patients were divided into 2 groups: the SBO group and the non-SBO group. We also analyzed the relationship between SBO and computed tomography (CT) scan image parameters.
Results
The study included 49 male and 47 female patients. The median age was 35.5 years (range, 14–72 years). We performed a 2- or 3-stage procedure as a total proctocolectomy and IPAA for patients with UC. SBO in the pretakedown of the loop ileostomy after IPAA occurred in 22 patients (22.9%). Moreover, surgical intervention for SBO was required for 11 patients. In brief, closure of the loop ileostomy was performed earlier than expected. A multivariate logistic regression analysis revealed that the 2-stage procedure (odds ratio, 2.850; 95% confidence interval, 1.009–8.044; P = 0.048) was a significant independent risk factor associated with SBO. CT scan image parameters were not significant risk factors of SBO.
Conclusion
The present study suggests that a 2-stage procedure is a significant risk factor associated with SBO after IPAA in patients with UC.

Abstract PDF

The two main diseases of inflammatory bowel disease are Crohn's disease and ulcerative colitis. The pathogenesis of inflammatory disease is that abnormal intestinal inflammations occur in genetically susceptible individuals according to various environmental factors. The consequent process results in inflammatory bowel disease. Medical treatment consists of the induction of remission in the acute phase of the disease and the maintenance of remission. Patients with Crohn's disease finally need surgical treatment in 70% of the cases. The main surgical options for Crohn's disease are divided into two surgical procedures. The first is strictureplasty, which can prevent short bowel syndrome. The second is resection of the involved intestinal segment. Simultaneous medico-surgical treatment can be a good treatment strategy. Ulcerative colitis is a diffuse nonspecific inflammatory disease that involves the colon and the rectum. Patients with ulcerative colitis need surgical treatment in 30% of the cases despite proper medical treatment. The reasons for surgical treatment are various, from life-threatening complications to growth retardation. The total proctocolectomy (TPC) with an ileal pouch anal anastomosis (IPAA) is the most common procedure for the surgical treatment of ulcerative colitis. Medical treatment for ulcerative colitis after a TPC with an IPAA is usually not necessary.

Abstract PDF: Restorative proctocolectomy (RPC) has become a standard procedure over 30 yr in patients with ulcerative colitis and familial adenomatous polyposis. However, there are several controversies in surgical method and strategy. From oncological point of view, mucosal proctectomy and hand-sewn ileal pouch anal anastomosis has advantage because of relatively complete removal of columnar epithelium. However, long-term follow-up results after stapled anastomosis revealed extremely low incidence of dysplasia in the anal transitional zone (ATZ). Furthermore, recent publication of 26 cancer occurrence after RPC showed more prevalence in mucosectomy group. Risk factors of dysplasia after RPC are supervening cancer or dysplasia on the proximal colon, long duration of symptom, and history of primary sclerosing cholangitis. Preservation of ATZ by stapled anastomosis may have functional superiority, which is supported by some manometric and functional studies. However, two randomized controlled trials showed no difference between the groups. Although there are some surgeons who advocate one stage RPC, majority of centers prefer two stage RPC with ileostomy. According to meta-analysis one stage RPC revealed 2-3 times frequent anastomotic leakage or pelvic sepsis. Five to ten percent of ulcerative colitis has some pathologic characteristics of Crohn's disease, which is classified as indeterminate colitis (IC). Long-term results of RPC in patients with IC revealed similar results with ulcerative colitis and superior to Crohn's disease. So RPC may be justified in patients with IC. Conclusively, RPC should be tailored according to clinicopathologic details and operative findings.

Abstract PDF: Malignant intestinal lymphoma complicating ulcerative colitis has been reported. Although the association of colorectal cancer with ulcerative colitis is well described, the association of intestinal lymphoma, ulcerative colitis and prior immunosuppression remains unclear. However, it is important to be aware of the possible risk of lymphoma and carcinoma when patients shows unexpected signs of deterioration or when the clinical course of ulcerative colitis is atypical. Substantial biopsies with colonoscopy are required to make an unequivocal diagnosis in such patients. We report the case of non-Hodgkin's lymphoma in ulcerative colitis with review of the literature.

Abstract PDF: PURPOSE
This study was performed to assess the complications and functional outcomes after a total proctocolectomy and ileal J-pouch anal anastomosis for patients with ulcerative colitis.
METHODS
We reviewed the medical records of 30 patients who had undergone a total proctocolectomy and ileal J-pouch anal anastomosis for ulcerative colitis from 1992 to 1999 in our hospital. We used questionnaires or telephone interviews to assess the functional outcomes of the patients. The median duration of follow-up was 23 months after the ileostomy take down.
RESULTS
The mean age of the patients at the definitive operation was 35.9 (+/-11.8). The indications for operation were medical intractability (76.7%), suspicious malignancy (13.3%), perforation (6.7%), and hemorrhage (3.3%). The double stapling method was used in 26 patients and the handsewn method in 4 patients. Of the 30 patients, 23 patients completed the functional analysis. Bowel frequency was 6.6 (+/- 2.6) per 24 hours, with 5.1 (+/- 2.1) in the daytime and 1.4 (+/-1.3) in the night. Fourteen patients (60.9%) had relatively mild incontinence, and four patients (17.4%) had to wear pads, especially at night. Eighteen patients (78.3%) were able to discriminate flatus from feces, and only one patient (4.3%) suffered from perianal irritation. Twelve patients (52.2%) had to restrict their diets, and five patients (21.7%) took antidiarrheal medications. Pouchitis occurred in three patients (13.0%). Sexual dysfunction was noted in four patients (17.4%), and urinary urgency in one patient (4.3%). There was no functional difference between the double stapling method and the handsewn method.
CONCLUSIONS
The functional outcomes after ileal J-pouch anal anastomosis for patients with ulcerative colitis were satisfactory, irrespective of the method of anastomosis.

Abstract PDF: PURPOSE
Restorative proctocolectomy (RP) is a standard surgery in patients with ulcerative colitis and familial adenomatous polyposis. Usually, diverting ileostomy is performed to protect an ileoanal anastomosis with RP. However, there are many controversies whether diverting ileostomy might urgently be needed. This study was performed to compare postoperative complications after RP with or without diverting ileostomy.
METHODS
Between July 1994 and June 2001, 77 (M : F= 45 : 32) patients underwent RP. The indication criteria for diverting ileostomy included tension at the anastomosis, positive leakage test, compromised blood flow in the ileal pouch, long-term and high-dose steroid use, and severe rectal inflammation in ulcerative colitis patients.
RESULTS
Histopathologic diagnoses revealed 45 ulcerative colitis, 23 familial adenomatous polyposis, 5 rectal cancer, and 4 hereditary nonpolyposis colorectal cancer. Diverting ileostomies were performed in 40 patients (51.9%) and closed approximately 4 months later. Fourty eight complications were present in 32 patients. There was no perioperative death. There was no difference in perioperative outcome, morbidity or functional status between patients with and without ileostomy. However, in ulcerative colitis patients, anastomosis leakage was more frequent in patients without ileostomy.
CONCLUSIONS
Restorative proctocolectomy can be safely performed without diverting ileostomy in most cases of RP. However, diverting ileostomy may reduce anastomosis leakage in patients with ulcerative colitis.

Abstract PDF: PURPOSE
Inflammatory bowel disease (IBD) has steadily increased, according to westernized life style, popular use of colonoscopy, and development of pathology and diagnostic radiology. However, there is no avaliable data about epidemiology of IBD in Korea. Even though our data is not a standard of IBD patients in Korea, it is possible to understand the trend of IBD.
METHODS
From Jan. 1995 to Dec. 2000, cases of ulcerative colitis (UC), Crohn's disease (CD), and indeterminate colitis (ID) were evaluated retrospectively. Annual incidence of IBD at our hospital was calculated with using new IBD patients/new out-patients. To compare the incidence of CD with that of intestinal tuberculosis (TB), intestinal TB cases from Jan. 1997 to Dec. 2000 were evaluated.
RESULTS
Total number of IBD patients was 651: UC (480, 73.7%), CD (149, 22.9%) and ID (22, 3.4%) in order of frequency. Male was more prevalent than female (1.2:1), especially in CD (2.5:1). However, there was no difference of sex in UC. Mean age was 37.9 ( 14.1) years old, ranging from 11 to 79. CD patients (25.1 9.4) were younger than UC (41.9 13.0). Incidence of IBD out of new out-patients increased annually:0.30% (53 cases) in 1995, 0.31% (67 cases) in 1996, 0.37% (99 cases) in 1997, 0.38% (100 cases) in 1998, 0.54% (158 cases) in 1999 and 0.58% (174 cases) in 2000. The most common types of UC and CD were proctitis (52.3%) and ileocolic type (59.7%), respectively. Incidence of CD was more prevalent than that of intestinal TB (2.5:1).
CONCLUSION
About 0.5% of new out-patients had IBD and the number of patients of IBD increased annually. CD patients were younger than those of UC and male was predominant. The number of patients with CD exceeded that of intestinal TB patients.

Abstract PDF: PURPOSE
To better understand the extent to which chemokines participate in the mucosal inflammatory response in patients with ulcerative colitis (UC), we assessed the expression of an array of chemokines in the colonic mucosa of UC patients.
METHODS
Colonic mucosal biopsy specimens were obtained from 15 patients with UC and 12 normal controls. Messenger RNA (mRNA) levels for 10 chemokines were quantitated by reverse-transcription PCR using synthetic standard RNAs. The biopsy specimens were also cultured, and secreted chemokines in culture supernatants were assayed by ELISA.
RESULTS
The mRNA expression of C-X-C (IL-8, GROalpha, GRObeta, GROgamma, ENA-78, and IP-10) and C-C (MCP-1, MIP-1beta, and RANTES), but not C (lymphotactin) chemokines was significantly higher in the affected mucosa of UC patients than in the unaffected mucosa of UC patients or in the normal mucosa of normal controls. The degree of increased expression was more prominent in the C-X-C than in the C-C chemokines. Further, the secretion of IL-8, GROalpha, ENA-78, and MCP-1 was higher in UC patients than in normal controls. Secretions of MIP-1beta and RANTES also showed a trend toward an increase in UC, but it did not reach statistical significance.
CONCLUSION
The increased expression of a variety of chemokines in UC suggest that chemokines may play an important role in the immunopathogenesis of UC.
