Inflammatory myofibroblastoma (IMT) is a rare solid tumor, and its etiology and pathogenesis are unclear. Crohn's disease is a non-specific intestinal inflammatory disease. The clinical manifestations, laboratory examinations, and imaging examinations of IMT are not specific, making diagnosis difficult. A case of Crohn's disease combined with IMT of abdominal wall was admitted to the Department of Gastroenterology at the Third Xiangya Hospital, Central South University, on Nov. 21, 2017. This patient was admitted to our hospital because of repeated right lower abdominal pain for 4 years. A 6 cm×5 cm mass was palpated in the right lower abdomen. After completing the transanal double-balloon enteroscopy and computed tomographic enterography for the small intestinal, the cause was still unidentified. The patient underwent surgery due to an abdominal wall mass with intestinal fistula on Sept. 12, 2018 and recovered well currently. According to histopathology and immunohistochemistry, he was diagnosed with Crohn's disease combined with IMT. Up to July 2020, the patients still took azathioprine regularly, without abdominal pain, abdominal distension, and other discomfort, and the quality of his life was good.

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.

Pediatric onset Crohn's disease (CD) tends to have complicated behavior (stricture or penetration) than elderly onset CD at diagnosis. Considering the longer duration of the disease in pediatric patients, the accumulative chance of surgical treatment is higher than in adult onset CD patients. Possible operative indications include perianal CD, intestinal stricture or obstruction, abdominal abscess or fistula, intestinal hemorrhage, neoplastic changes and medically untreatable inflammation. Growth retardation is an operative indication only for pediatric patients. Surgery can affect a patient's clinical course, especially for pediatric CD patient who are growing physically and mentally, so the decision should be made by careful consideration of several factors. The complex and diverse clinical conditions hinder development of a systemized treatment algorithm. Therefore, timing of surgery in pediatric CD patients should be determined with individualized approach by an experienced and well organized multidisciplinary inflammatory bowel disease team. Best long-term outcomes will require proactive post-operative monitoring and therapeutic modifications according to the conditions.

OBJECTIVETo evaluate the diagnostic value of preoperative CT enterography (CTE) on obstruction, fistula and abscess formation compared to intraoperative findings in patients undergoing surgery for Crohn's disease(CD), aiming to provide reference to clinical practice.

METHODSPreoperative CTE data of 176 CD patients confirmed by clinic, endoscopy, imaging, operation and pathology at the Department of General Surgery in Nanjing Jinling Hospital from January 2013 to December 2015 were enrolled in retrospective cohort study. All the patients underwent enhanced full abdominal CT scan using SIMENS SOMATOM Definition Flash 64 row dual-source CT machine. CTE scans were performed from the dome of diaphragm to the symphysis pubis. The CT images in arterial and venous phase were reconstructed with 1.0 mm thin layer, and then processed in MMWP 4.0 workstation including multi-planar recombination, surface recombination and maximum density projection. The sensitivity, specificity, positive and negative predictive value, false negative rate and accuracy of preoperative CTE on obstruction, fistula and abscess were compared with intraoperative findings.

RESULTSAmong 176 patients, 122 were males and 54 were females with median age of 29 (18 to 65) years, median disease duration of 48 (1 to 240) months, median time interval from CT scan to operation of 16(1 to 30) days, and median body mass index of 17.8 (10.8 to 34.7) kg/m. Twenty-six cases (14.8%) had nutritional risk (NRS2002≥3); 23 cases (13.1%) had lesions limited to ileum; 19 cases (10.8%) had lesions limited to colon; 126 cases (71.6%) had simultaneous lesions of ileum and colon, and 8 cases (4.5%) had lesion in upper gastrointestinal tract. A total of 199 lesions of small intestine were identified by preoperative CTE, including 131 of obstruction (65.8%), 42 of fistula (21.1%), and 26 of abscess (13.1%), while 235 lesions were confirmed by operation, including 133 of obstruction (56.6%), 74 of fistula (31.5%), 28 of abscess (11.9%). The modification of planned surgical procedure due to unexpected intraoperative findings were found in 29(16.5%) patients. The sensitivity, specificity, positive predictive value and negative predictive value of preoperative CTE were 86.4%, 78.8%, 86.9% and 76.0% for obstruction; 83.8%, 79.1%, 67.5% and 90.4% for fistula; and 96.2%, 98.0%, 90.1% and 99.3 for abscess, respectively.

CONCLUSIONPreoperative CTE can effectively evaluate the lesions of intestinal obstruction, fistula and abscess in CD patients, with the highest accuracy of abscess, and has quite good consistency with intraoperative findings, which may be used as the first choice of imaging diagnosis of CD.

A 66-year-old male with dyspepsia and weight loss was referred to our hospital for evaluation. On laboratory examination, anti-saccharomyces cerevisiae (ASCA)-IgA was positive and iron deficiency anemia was present. PET/CT and abdominal CT scan images showed multiple small bowel segmental wall thickening and inflammation. Capsule endoscopy images showed multiple small bowel ulcerative lesions with exudates. Based on laboratory test results and imaging studies, the patient was diagnosed with Crohn's disease and treated with prednisolone and 5-aminosalicylic acid (5-ASA). However, the patient underwent second operation due to small bowel perforation within 2 month after initiation of treatment. Pathology report of the resected specimen was compatible to primary small bowel diffuse large B cell lymphoma and pertinent treatment was given to the patient after recovery. Herein, we describe a case of primary small bowel diffuse large B cell lymphoma that was mistaken for Crohn's disease.

Plummer-Vinson syndrome manifests as cervical dysphagia, iron deficiency anemia, an upper esophageal web, and atrophic glossitis. The cause of the esophageal web is thought to be iron deficiency anemia; however, the cause of Plummer-Vinson syndrome has not been established. Crohn's disease is usually accompanied by malnutrition and iron deficiency anemia; however, no case of concomitant Crohn's disease and Plummer-Vinson syndrome with aggravated malnutrition and anemia has been previously reported. Here, we report on a rare case of Plummer-Vinson syndrome in a Crohn's disease patient, which caused malnutrition and constipation.

This report describes two non-cirrhotic patients with portal vein thrombosis who underwent successful balloon occlusion retrograde transvenous obliteration (BRTO) of gastric varices with a satisfactory response and no complications. One patient was a 35-year-old female with a history of Crohn's disease, status post-total abdominal colectomy, and portal vein and mesenteric vein thrombosis. The other patient was a 51-year-old female with necrotizing pancreatitis, portal vein thrombosis, and gastric varices. The BRTO procedure was a useful treatment for gastric varices in non-cirrhotic patients with portal vein thrombosis in the presence of a gastrorenal shunt.

Duodeno-colonic fistula is an enterocolonic fistula that occurs as a complication of Crohn's disease. Symptoms of duodeno-colonic fistula are similar to those of Crohn's disease, such as weight loss and diarrhea. The treatment of choice is surgery, although medical treatment may also be considered. However, surgery is recommended when all available medical therapies have been ineffective. In this case, we report a secondary duodeno-colonic fistula due to Crohn's disease that was temporarily managed by an endoscopic procedure with a detached endoloop and hemoclips as a bridging therapy to final surgical repair.

Crohn's disease is characterized by chronic transmural inflammation of the bowel and is associated with serious complications, such as bowel strictures, abscesses, fistula formation, and perforation. As neither medical nor surgical therapy provides a cure for Crohn's disease, the primary goals of therapy are to induce and maintain remission and prevent complications. As a biologic agent, infliximab, a monoclonal antibody to tumor necrosis factor, is indicated for refractory luminal and fistulizing Crohn's disease that does not respond to other medical therapies or surgery. Infliximab has proven to be very effective for inducing and maintaining remission in Crohn's disease; however, infliximab treatment has several potential complications. Here, we report a case of free perforation following a therapeutic response after an initial dose of infliximab for Crohn's disease. This is the first case report describing a free perforation in a Crohn's disease patient after an initial dose of infliximab.

Azathioprine is frequently used for the treatment of inflammatory bowel diseases (IBD) such as Crohn's disease and ulcerative colitis. Lymphomas, squamous cell carcinomas, and undifferentiated pleomorphic sarcomas have been reported among patients receiving azathioprine therapy. Herein, we report a case of pleomorphic liposarcoma of chest wall which occurred in a 44-year-old man with Crohn's disease taking azathioprine. He was diagnosed with Crohn's disease 3 years ago after suffering from abdominal pain and hematochezia for 12 years. He had been taking 50 mg of azathioprine per day for 23 months when he visited the thoracic and cardiovascular surgery clinic due to right chest palpable mass that had rapidly grown during the past 2 months. Excisional biopsy was performed and the mass was diagnosed as pleomorphic liposarcoma. Therefore, he underwent radical excision of the right chest wall mass, which measured 11.0x6.5 cm in size. He is scheduled to receive radiation therapy and chemotherapy.
