Metastatic clear-cell renal carcinoma: an exceptional cause of ileocolonic intussusception in adults

Introduction: Intussusceptions in adults are rare, representing 1% to 5% of intestinal obstructions in this age group. This condition can be caused by benign and malignant lesions acting as lead points, the latter being the most frequent. Furthermore, the diagnosis is challenging due to the non-specific symptoms with variable duration. Case Presentation: A 43-year-old man, with a history of localized clear-cell renal carcinoma (ccRCC) treated 9 years earlier with a right radical nephrectomy, presented with bowel obstruction symptoms. An abdominal computed tomography scan showed an ileocolonic intussusception. Hence, the patient required a right hemicolectomy with ileotransverse anastomosis. The histopathological analysis showed a metastatic ccRC to the terminal ileum causing the intussusception. Discussion: Adult intussusceptions are rare. However, they should be considered in the differential diagnosis of patients with abdominal pain and symptoms of bowel obstruction. Metastases of renal cancer to the small bowel are uncommon and even more so in the form of intussusception. Definitive treatment must be tailored to the patient's condition and underlying cause.

Cistoadenoma mucinoso de la válvula ileocecal: tumoración intestinal infrecuente en un niño de 1 año. Reporte de caso / Mucinous cystadenoma of the ileocecal valve. Uncommon intestinal tumor in a oneyear-old boy. Case report

RESUMEN El cistoadenoma mucinoso se encuentra usualmente en el ovario, páncreas y el apéndice, pero su presentación en el intestino es extremadamente rara. En este reporte de caso, presentamos a un niño con obstrucción parcial intestinal debido a un cistoadenoma mucinoso en la válvula ileocecal. En la cirugía se retiró el íleo terminal, válvula ileocecal, ciego y apéndice, seguido de anastomosis ileocecal. El paciente evolucionó favorablemente en el postoperatorio y se recuperó sin contratiempos. A nuestro entender, este es el primer reporte de presentación de este tumor en dicha localización.

ABSTRACT Mucinous cystadenoma is usually found in the ovary, pancreas and appendix but its presentation in the intestine is extremely rare. In this case report we present an infant with partial intestinal occlusion due to a mucinous cystadenoma of the ileocecal valve. We performed an excision of the terminal ileum, ileocecal valve, cecum and appendix, followed by ileocolic anastomosis. The patient did well after the procedure and recovered uneventfully. To our knowledge, this is the first case report of this tumor in this location.

Intussusception Caused by Colon Cancer in Pregnancy / 대한소화기학회지

Intussusception is a common in pediatric age group. But it is rare in adults. And intussusception caused by tumor account for 1% of bowel obstructions in adult. Intussusception is an extremely rare cause of abdominal pain in pregnancy. In particular, cases of Intussusception due to colorectal cancer during pregnancy have never been reported in Korea. Our patient is a 34 years old woman who presented at 14 weeks of her second pregnancy. She presented with right lower abdominal discomfort and intermittent palpable mass which was usually spontaneously resolved. In the MRI study, pathologic asymmetric wall thickening was still noted and ileocolic intussusception was noted, and in colonoscopy, there was ulcerofungating mass around ileocecal valve which may be a leading point of intussusception. Biopsy was done. Pathologic finding was poorly differentiated adenocarcinoma. Under the patient agreement, we performed dilatation and curettage and laparoscopic right hemicolectomy and lymph node dissection. Now she is receiving a FOLFOX chemotherapy.

The effect of ileocecal valve removal in a model of short bowel syndrome / Efeito da remoção da válvula ileocecal em modelo de síndrome do intestino curto

ABSTRACT Background : Short bowel syndrome is a harmful condition that needs experimental research. Aim: To assess the impact of the ileocecal valve removal in a model of short bowel syndrome, in order to investigate the evolution of the colon under this circumstance. Method: Fifteen Wistar rats were equitable divided into: Control (Sham), Group I (70% enterectomy preserving ileocecal valve) and Group II (70% enterectomy excluding ileocecal valve). After enterectomy was performed jejunoileal or jejunocecal anastomosis and sacrificed the animals on 30th postoperative day for histomorphometric study of the colon. During this period, was observed the clinical evolution of the animals weekly including body weight measurement. Results: Group I and II presented progressive loss of weight. In Group I was observed diarrhea, perineal hyperemia and purple color of the colon during autopsy. Histomorphometry assay showed hypertrophy and hyperplasia of colon mucosa in Group I. In Group II the colon wall was thicker due to hypertrophy and muscular hyperplasia, and in mucosa vascular proliferation and inflammatory infiltrate were intense. Conclusion : This short bowel syndrome model is relevant and achieve 100% of survival. Animal's weight loss was not altered by the presence or exclusion of the ileocecal valve. Animals with 70% of small bowel removal and presence of the ileocecal valve attained a better clinical evolution and histological colon adaptation than those without ileocecal valve.

RESUMO Racional: Síndrome do intestino curto é condição clínica crítica e que precisa de pesquisa experimental. Objetivo: Avaliar o impacto da remoção da válvula ileocecal em um modelo de síndrome do intestino curto para investigar o comportamento do cólon nesta circunstância. Método: Quinze ratos Wistar foram divididos em três grupos de cinco: Controle (Sham), grupo I (enterectomia de 70% com preservação da válvula ileocecal), e grupo II (70% enterectomia de 70% excluindo a válvula ileocecal). Após a enterectomia foi restabelecido o trânsito com anastomose jejunoileal no grupo I e jejunocecal no grupo II. Os animais foram sacrificados no 30º dia do pós-operatório para histomorfometria do cólon. Durante este período, observou-se a evolução clínica semanal, incluindo a medição do peso corporal. Resultados: Grupos I e II apresentaram perda progressiva de peso. No grupo I houve diarreia, períneo hiperemiado e cor violácea do cólon durante a autópsia. A histomorfometria mostrou hipertrofia e hiperplasia da mucosa do cólon no grupo I. No grupo II a parede do cólon estava mais espessa devido à hipertrofia e hiperplasia das camadas muscular e mucosa onde a proliferação vascular e infiltração inflamatória foi intensa. Conclusão: Este modelo é factível e atingiu 100% de sobrevida. A perda de peso não foi alterada pela presença ou exclusão da válvula ileocecal. Animais com remoção de 70% do intestino delgado e presença da válvula ileocecal apresentaram melhor evolução clínica e adaptação histológica do cólon que os sem válvula ileocecal.

Tumor neuroendocrino de la válvula ileocecal con metástasis hepática única. Presentación de caso / A case of a neuroendocrine tumor of the ileocecal valve with a single hepatic metastasis

Resumen Los tumores neuroendocrinos (TNE) del tracto gastrointestinal son muy infrecuentes, el intestino delgado y principalmente el íleon son los sitios donde ocurren con mayor frecuencia. Tienen la capacidad de secretar péptidos y aminas bioactivas. La Organización Mundial de la Salud (OMS) los clasifica de acuerdo con el grado de diferenciación y conducta biológica en 5 grados. Las manifestaciones clínicas pueden estar ausentes o ser inespecíficas. Se reporta el caso de un paciente de 49 años de edad quien fue ingresado por dolor abdominal en hemiabdomen derecho, acompañado de aerogastria, vómitos y síndrome constitucional; en el examen físico se encontró hepatomegalia dolorosa con nódulo único de 2,5 cm aproximadamente. La citología por aspiración con aguja fina (CAFF) y la laparoscopia con biopsia diagnosticaron una metástasis hepática única de un TNE de origen gastrointestinal, que se confirmó con la colonoscopia con ileoscopia encontrando un tumor subepitelial en la válvula ileocecal. La inmunohistoquímica realizada ayudó a la confirmación del diagnóstico. El tratamiento puede ser quirúrgico; sin embargo, este paciente rechazó esta terapia, por lo que se trató con quimioterapia y radioterapia. Lo fundamental en esta entidad es el diagnóstico precoz, que pocas veces se realiza por lo infrecuente de la enfermedad.

Abstract Neuroendocrine tumors of the gastrointestinal tract are very rare tumors that most frequently occur in the small intestine, primarily in the ileum. They secrete bioactive peptides and amines. The World Health Organization (WHO) classifies them into five grades according to the degree of differentiation and biological behavior. Clinical manifestations may be absent or nonspecific. We report the case of a 49-year-old patient who was admitted due to abdominal pain in the right hemiabdomen, accompanied by aerogastria, vomiting and constitutional syndrome. A painful hepatomegaly with a single nodule of approximately 2.5 cm was found during physical examination. CAFF and laparoscopy with biopsy diagnosed a single hepatic metastasis of a neuroendocrine tumor of gastrointestinal origin. This was confirmed by colonoscopy with ileoscopy which found a subepithelial tumor in the ileocecal valve. Immunohistochemistry helped confirm the diagnosis. Treatment for this type of tumor can be surgical, but this patient rejected surgery. It was treated with chemotherapy and radiation therapy. Early diagnosis of this entity is fundamental but is rare because of the infrequency of the disease.

Ileocecal Mucosal Involvement of Blastic Plasmacytoid Dendritic Cell Neoplasm without Skin Lesions / 대한내과학회지

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a relatively rare hematological malignancy, and most cases present with characteristic skin lesions. The skin lesions appear as nodules, plaques, and bruise-like macules with redness or ulcerations. BPDCN without skin lesions is rare. Cases with hepatosplenomegaly, pulmonary involvement, multiple lymphadenopathies, renal masses, sinonasal sinus, and subcutaneous masses have also been reported. Here, we report the first case of ileocecal valve involvement of BPDCN without skin lesions.

Tuberous Sclerosis Complex with Crohn's Disease / 대한소아신경학회지

Tuberous sclerosis complex (TSC) is an autosomal dominant disorder caused by mutation of one of two genes, TSC1 (encoding hamartin, 9q34) and TSC2 (encoding tuberin, 16p13). It invades the central nervous system and various parts of the body, causing various symptoms. Crohn's disease (CD) is a chronic immune-mediated disease that has not been clearly elucidated. It is thought to be caused by an excessive immune response of the body to bacteria that normally exist in the digestive tract with genetic factors. No cases have been reported in which both of the above-mentioned diseases occurred simultaneously. We report a case of CD in a patient with TSC. A 12-year-old boy was brought to our hospital because of abdominal pain. Skin lesions were observed in the TSC. Fundus examination revealed a hamartoma in the right retina. Brain magnetic resonance imaging revealed a subendothelial giant cell astrocytoma (SEGA). On the basis of these findings, he was diagnosed as having TSC. Blood test results showed increased levels of inflammatory markers. On abdominal ultrasonography, his colon walls were observed to be thickened with increased vascularity of the proximal ascending colon, ileocecal valve, and terminal ileum. Colonoscopy revealed discontinuous ulcerations and inflammations of the ileum, IC valve, and cecum, similar to those found in CD. Everolimus was administered orally for the SEGA but was discontinued frequently owing to the exacerbation of CD. The possibility of CD should be kept in mind in patients with TSC considering to undergo treatment for SEGA.

Successful Ultrasound-Guided Gastrografin Enema for Very Low Birth Weight Infants with Meconium-Related Ileus

PURPOSE: Meconium-related ileus is common in preterm infants. Without proper management, it can cause necrotizing enterocolitis and perforation requiring emergent operation. This study was conducted to describe the efficacy and safety of ultrasound-guided Gastrografin enema at bedside for preterm infants with meconium-related ileus. METHODS: Between March 2013 and December 2014, this study enrolled preterm infants with birth weight < 1,500 g, who were diagnosed with meconium-related ileus requiring ultrasound-guided Gastrografin enema refractory to glycerin or warm saline enemas. Gastrografin was infused until it passed the ileocecal valve with ultrasound guidance at bedside. RESULTS: A total of 13 preterm infants were enrolled. Gestational age and birth weight were 28.6 weeks (range, 23.9–34.3 weeks) and 893 g (range, 610–1,440 g), respectively. Gastrografin enema was performed around postnatal day 8 (range, day 3–11). The success rate was 84.6% (11 of 13 cases). Three of these 11 infants received a second procedure, which was successful. Among 2 unsuccessful cases, one failed to pass meconium while the other required surgery due to perforation. The time required to pass meconium was 2.8±1.5 hours (range, 1–6 hours). The time until radiographic improvement was 2.8±3.4 days (range, 1–14 days) after the procedure. CONCLUSION: Ultrasound-guided Gastrografin enema at bedside as a first-line treatment to relieve meconium-related ileus was effective and safe for very low birth weight infants. We could avoid unnecessary emergent operation in preterm infants who have high postoperative morbidity and mortality. This could also avoid transporting small preterm infants to fluoroscopy suite.

Triplicación tubular total de colon asociado a malformación ano rectal: reporte de un caso / Total tubular triplication of colon with anorectal malformation: a case report

La triplicación tubular total de colon es un caso único de presentación en nuestro medio, existen solo 9 casos reportados hasta el 2009 en la literatura mundial. Es una rara variación de la duplicación del intestino posterior, la patogenia probablemente sea similar al de la duplicación colónica. Se presenta el caso de un paciente varón de 38 semanas de gestación con malformación ano rectal, sin fístula evidente, se sometió a cirugía para sigmoidostomia. Ante el hallazgo inesperado del sigmoides triplicado se revisó todo el colon, encontrándose en toda su longitud, tres segmentos unidos entre sí, sin posibilidad de división uno del otro. El postoperatorio cursó sin complicaciones, sin embargo, el paciente falleció por Neumonia Staphilococica Multiresistente, 15 meses después, tras reiterados cuadros respiratorios. Se informa este caso, por la rareza de su conformación, la ausencia de reportes en la literatura nacional y muy escasas patologías con similares características de presentación a nivel mundial.

The total tubular triplication of the colon is a unique case reported in our environment; only 9 cases were reported up to 2009 in world literature. It's a rare variation of hindgut duplication, the pathogenesis is probably a similar theory of colonic duplication. A case report of 38 weeks of gestation male patient with anorectal malformation and without evident fistula; the patient had undergone surgery for sigmoidostomy. The unexpected finding of triplication sigmoid led to the complete evaluation of the colon. Consequently, it was found three joined segments in the whole length with any possibility to separate one from another. The postoperative period was without complications however, the patient died because of a Multi-Resistant Sthaphylococcus Pneumonia The present case is reported due to the rarity of its conformation and the absence of reports in the national literature and more little patholgyes with similar characteristics of presentation.

Bacterial translocation and mortality on rat model of intestinal ischemia and obstruction

Abstract Purpose: To develop an experimental model of intestinal ischemia and obstruction followed by surgical resection of the damaged segment and reestablishment of intestinal transit, looking at bacterial translocation and survival. Methods: After anesthesia, Wistar rats was subject to laparotomy, intestinal ischemia and obstruction through an ileal ligature 1.5cm of ileum cecal valve; and the mesenteric vessels that irrigate upstream of the obstruction site to approximately 7 to 10 cm were ligated. Abdominal wall was closed. Three, six or twenty-four hours after, rats were subject to enterectomy followed by an end to end anastomosis. After 24h, mesenteric lymph nodes, liver, spleen and lung tissues were surgically removed. It was studied survival rate and bacterial translocation. GraphPadPrism statistical program was used. Results: Animals with intestinal ischemia and obstruction for 3 hours survived 24 hours after enterectomy; 6hx24h: survival was 70% at 24 hours; 24hx24h: survival was 70% and 40%, before and after enterectomy, respectively. Culture of tissues showed positivity on the 6hx24h and negativity on the 3hx24h. Conclusion: The model that best approached the clinic was the one of 6x24h of ischemia and intestinal obstruction, in which it was observed bacterial translocation and low mortality rate.

Intensive Nutrition Management in a Patient with Short Bowel Syndrome Who Underwent Bariatric Surgery

Many individuals with short bowel syndrome (SBS) require long-term parenteral nutrition (PN) to maintain adequate nutritional status. Herein, we report a successful intestinal adaptation of a patient with SBS through 13 times intensive nutritional support team (NST) managements. A thirty-five-year-old woman who could not eat due to intestinal discontinuity visited Seoul National University Hospital for reconstruction of the bowel. She received laparoscopic Roux-en-Y gastric bypass (RYGB) due to morbid obesity in Jan 2013 at a certain hospital and successfully reduced her weight from 110 kg to 68 kg. However, after a delivery of the second baby by cesarean section in Jul 2016, most of small bowel was herniated through Peterson’s defect, and emergent massive small bowel resection was performed. Thereafter, she visited our hospital for the purpose of intestinal reconstruction. In Sep 2016, she received side–to-side gastrogastrostomy and revision of double barrel enterostomy. The remaining small bowel included whole duodenum, 30 cm of proximal jejunum, and 10 cm of terminal ileum. Pylorus and ileocecal valves were intact. The patient given only PN after surgery was provided rice-based soft fluid diet after 10 day of operation. Through intensive nutritional management care, she could start solid meals, and finally stop the PN and eat only orally at 45 days postoperatively. Three nutritional interventions were conducted over 2 months after the patient was discharged. She did not require PN during this period, and maintained her weight within the normal weight range. Similar interventions could be used for other patients with malabsorption problems similar to SBS.

Endoscopic Diagnosis and Differentiation of Inflammatory Bowel Disease

Patients with inflammatory bowel disease have significantly increased in recent decades in Korea. Intestinal tuberculosis (ITB) and intestinal Behcet's disease (BD), which should be differentiated from Crohn's disease (CD), are more frequent in Korea than in the West. Thus, the accurate diagnosis of these inflammatory diseases is problematic in Korea and clinicians should fully understand their clinical and endoscopic characteristics. Ulcerative colitis mostly presents with rectal inflammation and continuous lesions, while CD presents with discontinuous inflammatory lesions and frequently involves the ileocecal area. Involvement of fewer than four segments, a patulous ileocecal valve, transverse ulcers, and scars or pseudopolyps are more frequently seen in ITB than in CD. A few ulcers with discrete margins are a typical endoscopic finding of intestinal BD. However, the differential diagnosis is difficult in many clinical situations because typical endoscopic findings are not always observed. Therefore, clinicians should also consider symptoms and laboratory, pathological, and radiological findings, in addition to endoscopic findings.

Manejo quirúrgico de la intusucepción Íleo Ilear e Íleo Cólica. Reporte de un caso. / Surgical management of the ileus ileal and ileocolic intussusception: case report

Introducción: la invaginación intestinal, que consiste en el telescopaje de una parte del intestino dentro de otra, es la causa más común de obstrucción intestinal en los niños de 3 meses a 5 años. La intususcepción puede ser clasificada por su etiología o más comúnmente por su punto de origen. La localización ileocólica representa alrededor del 90% de los casos. El diagnóstico de la invaginación intestinal puede ser difícil y requiere de una alta sospecha clínica, sobre todo cuando los síntomas y signos típicos no están presentes. La radiografía simple de abdomen y el ultrasonido son los estudios más utilizados para el diagnóstico de la intususcepción intestinal. En un gran número de pacientes, la invaginación puede ser reducida sin necesidad de cirugía, sin embargo, el fracaso de estos métodos no invasivos, el retraso en el manejo inicial y la presencia de signos que sugieran peritonitis son indicaciones claras de laparotomía. Caso: se presenta el caso de una paciente de 2 meses de edad con intususcepción intestinal ileo-ilear e ileo-cólica con manejo quirúrgico. Palabras clave: intususcepción, invaginación, obstrucción intestinal.

Introduction: intussusception, which is the telescoping of a portion of the intestine into another, is the most common cause of intestinal obstruction in children 3 months to 5 years. Intussusception can be classified by etiology or more commonly by point of origin. The ileocolic location represents about 90% of cases. The diagnosis of intussusception can be difficult and requires a high clinical suspicion, especially when the typical signs and symptoms are not present. Plain abdominal radiography and ultrasound studies are used for diagnosis of intestinal intussusception. In a large number of patients, intussusception can be reduced without surgery, however, failure of noninvasive methods, the delay in initial treatment and the presence of signs suggesting peritonitis are clear indications of laparotomy. Case: a case report of a 2 months age patient with ileo-ilear and ileo-colic intussusception with surgical management.

A Case of Recurrent Small Bowel Obstruction caused by a Mesodiverticular Band of Meckel Diverticulum / 대한내과학회지

Meckel diverticulum is the most common congenital anomaly of the gastrointestinal system. Although it is commonly asymptomatic in adults, Meckel diverticulum can lead to intussusception, volvulus, inflammatory adhesions, or an internal hernia. However, small bowel obstruction due to a mesodiverticular band of Meckel diverticulum is rare. We report a case of a 24-year-old man who complained of abdominal pain and vomiting caused by recurrent small bowel obstruction. He had undergone no previous abdominal surgery. Abdominal computed tomography revealed a transition point at the mid-to-distal ileum. To identify the cause of the obstruction, we performed single-balloon enteroscopy, which revealed extrinsic compression at the proximal ileum 100 cm from the ileocecal valve. After marking the obstruction site, subsequent laparoscopy revealed a Meckel diverticulum with a mesodiverticular band, which entrapped a bowel loop and caused the recurrent small bowel obstruction. The patient was treated successfully with laparoscopic diverticulectomy.

Endoscopic Treatment of a Symptomatic Ileal Lipoma with Recurrent Ileocolic Intussusceptions by Using Cap-Assisted Colonoscopy

A 73-year-old woman presented with intermittent abdominal pain and weight loss of 15 kg for 2 years. Colonoscopy revealed an erythematous polypoid tumor with a long and wide stalk in the cecum, but with air inflation, it abruptly went away through the ileocecal valve (ICV). An abdominal computed tomography showed a well-demarcated pedunculated subepithelial mass of 2.6x2.7 cm size with fat attenuation in the terminal ileum. It was an intussusceptum of the ileal lipoma through the ICV. This ileal lipoma was causing her symptoms because repeated ileocolic intussusceptions resulted in intermittent intestinal obstructions. In order to avoid surgical sequelae of ileal resection, snare polypectomy using cap-assisted colonoscopy technique was performed within the ileum without complications. The histopathology report confirmed it as a subepithelial lipoma. After endoscopic resection of the ileal lipoma, the patient has been free of symptoms and was restored to the original weight.

Adenocarcinoma arising from Meckel's diverticulum in the ileum with malrotation of the midgut / 대한외과학회지

Meckel's diverticulum (MD) is a true congenital diverticulum that is remnant by incomplete obliteration of the omphalomesenteric duct. It is the most common congenital anomaly of the gastrointestinal tract, with an estimated prevalence of 2% (0.3% to 3% in autopsy studies). About 90% of MD occurs within 100 cm of the ileocecal valve. A primary malignant tumor arising within an MD is extremely uncommon. Malignancies are reported to account for only 0.5% to 3.2% of the complications. Carcinoids are the most common malignant tumors occurring in MD. Adenocarcinomas are extremely uncommon and very poor prognosis has been reported. We report a case of radiographically diagnosed chronic inflammatory mass caused by adenocarcinoma arising from MD in the ileum with malrotation of the midgut incidentally discovered at exploration.

Clinical Features of Symptomatic Meckel's Diverticulum in Children: Comparison of Scintigraphic and Non-scintigraphic Diagnosis / 대한소아소화기영양학회지

PURPOSE: Meckel's diverticulum (MD) has various clinical manifestations, and diagnosis or selectection of proper diagnostic tools is not easy. This study was conducted in order to assess the clinical differences of MD diagnosed by scintigraphic and non-scintigraphic methods and to find the proper diagnostic tools. METHODS: We conducted a retrospective review ofthe clinical, surgical, radiologic, and pathologic findings of 34 children with symptomatic MD, who were admitted to Gachon University Gil Medical Center, Inha University Hospital, and The Catholic University of Korea, Incheon St. Mary's Hospital between January 2000 and December 2012. The patients were evaluated according to scintigraphic (12 cases; group 1) and non-scintigraphic (22 cases; group 2) diagnosis. RESULTS: The male to female ratio was 7.5 : 1. The most frequent chief complaint was lower gastrointestinal (GI) bleeding in group 1 and nonspecific abdominal pain in group 2, respectively. The most frequent pre-operative diagnosis was MD in both groups. Red blood cell (RBC) index was significantly lower in group 1. MD was located at 7 cm to 85 cm from the ileocecal valve. Four patients in group 1 had ectopic gastric tissues causing lower GI bleeding. The most frequent treatment modality was diverticulectomy in group 1 and ileal resection in group 2, respectively. CONCLUSION: To diagnose MD might be delayed unless proper diagnostic tools are considered. It is important to understand indications of scintigraphic and non-scintigraphic methods according to clinical and hematologic features of MD. Scintigraphy would be weighed in patients with anemia as well as GI symptoms.

A Case of Intestinal Tuberculosis with Perianal Fistula Diagnosed after 30 Years / 대한소화기학회지

Tuberculosis can occur anywhere in the gastrointestinal tract. However, anorectal tuberculosis has rarely been reported. A 46-years-old male presented with abdominal pain and perianal discharge of 30 years' duration. The patient had received operations for anal fistula and inflammation three times. Although he had been taking mesalazine for the past three years after being diagnosed with Crohn's disease, his symptoms persisted. Colonoscopy performed at our hospital revealed cicatricial change of ileocecal valve and diffuse ulcer scar with mild luminal narrowing of the ascending, transverse, and descending colon without active lesions. Multiple large irregular active ulcers were observed in the distal sigmoid and proximal rectum. An anal fistula opening with much yellowish discharge and background ulcer scar was observed in the anal canal. However, cobble-stone appearance and pseudopolyposis were not present. Therefore, we clinically diagnosed him as having intestinal tuberculosis with anal fistula and prescribed antituberculosis medications. Follow-up colonoscopy performed 3 months later showed much improved multiple large irregular ulcers in the distal sigmoid colon and proximal rectum along with completely resolved anal fistula without evidence of pus discharge.
