ABSTRACT

Introducción: el sarcoma fibromixoide de bajo grado (LGFMS) se considera un tumor de tejidos blandos raro, que tiene tendencia a surgir del tronco y de las extremidades inferiores, su localización en el área intraabdominal se considera poco común. Objetivo: describir un caso de LGFMS primario de colon transverso perforado con metástasis hepática. Caso clínico: describimos el caso de un paciente masculino de 57 años con dolor abdominal de inicio súbito; en la cirugía se encontró un tumor con absceso y perforación en el colon transverso que infiltraba hasta la raíz del mesenterio. Se realizó hemicolectomía izquierda extendida con colostomía de colon ascendente. Más tarde, en una exploración posoperatoria, se encontró que tenía enfermedad hepática metastásica. Conclusiones: este caso es único en términos de ubicación y presentación. Es un recordatorio del diagnóstico diferencial del dolor abdominal agudo. Hasta donde sabemos, es el primer caso de LGFMS del colon con metástasis hepática sincrónica.


Background: Low grade fibromyxoid sarcoma (LGFMS) is considered a rare soft tissue tumor and has a tendency to arise from deep soft tissue of the trunk and lower extremities, the intraabdominal area is considered a rare location. Objective: To describe the first case of a LGFMS arising from the transverse colon with liver metastasis Clinical case: We describe a 57-years-old male patient with abdominal pain of sudden onset; at surgery he was found to have an abscessed tumor in the transverse colon that infiltrated to mesentery root. An extended left hemicolectomy was performed with ascending colon colostomy. Later on, a postoperative scan he was found to have metastatic liver disease Conclusions: This case is unique in terms of the location and presentation. It's a reminder of differential diagnosis of acute abdominal pain. To our knowledge is the first case of a LGFMS of the colon with synchronous liver metastasis.

ABSTRACT

RESUMEN Introducción: El cáncer avanzado es aquel que crece fuera del órgano en el cual se originó. La resección quirúrgica es el método más eficaz para lograr la curación de cáncer colorrectal en 50 por ciento de los casos. Objetivo: Evaluar los resultados del tratamiento multidisciplinar, realizado a pacientes con diagnóstico de cáncer colorrectal avanzado. Método: Se realizó un estudio observacional, descriptivo, ambispectivo y de corte transversal en el Hospital Clínico Quirúrgico "Hermanos Ameijeiras" entre enero de 2013 y diciembre de 2018. La muestra fue de 219 casos. Resultados: El 34,2 por ciento de los pacientes tenían entre 70 y 79 años. Hubo predominio de localización en colon ascendente (37,4 por ciento), en 57,1 por ciento fue moderadamente diferenciado y en 34,2 por ciento en estadio IIIA. El 7,8 por ciento de los pacientes tuvo recaída con metástasis, de ellos, 70,5 por ciento en hígado. En 72,6 por ciento la vía de acceso fue laparoscópica. En 50,7 por ciento se realizó hemicolectomía derecha. Las complicaciones se observaron en 25 pacientes (35,2 por ciento). El 91,3 por ciento de los casos recibió terapia adyuvante. En 27,4 por ciento hubo recurrencia. En el análisis del tiempo libre de enfermedad y de la supervivencia se obtuvieron buenos resultados. Conclusiones: El tratamiento combinado, secuencial y multidisciplinario en enfermedad maligna colorrectal avanzada ha demostrado beneficios clínicos y mayor supervivencia.

ABSTRACT Introduction: advanced cancer is cancer that has grown outside the organ in which it originated. Surgical resection is the most effective method to achieve colorectal cancer cure in 50 % of cases. Objectives: the objective was to evaluate the results of the multidisciplinary treatment, carried out on patients diagnosed with advanced colorectal cancer. Method: it is an observational, descriptive, ambispective and cross-sectional study at the "Hermanos Ameijeiras" Surgical Clinical Hospital between January 2013 and December 2018. The sample was 219 cases. Results: 34.2 percent of the patients were between 70 and 79 years old. 56.2 percent were women. There was a predominance of localization in the ascending colon (37.4 percent), in 57.1 percent it was moderately differentiated and in 34.2 percent in stage IIIA. 7.8 percent of the patients had a metastatic relapse, 70.5 percent of them in the liver. In 72.6 percent, the access route was laparoscopic. Right hemicolectomy was performed in 50.7 percent. Complications were observed in 25 patients (35.2 percent). 91.3 percent of the cases received adjuvant therapy. In 27.4 percent there was recurrence. Good results were obtained in the analysis of disease-free time and survival. Conclusion: we conclude that combined, sequential, and multidisciplinary treatment in advanced colorectal malignancy has demonstrated clinical benefits and increased survival. With an acceptable morbidity and mortality related to the surgical procedure regardless of the access route used. Multivisceral and / or en bloc resections and maximum resection manage to increase the free interval of disease progression and alleviate symptoms(AU)

ABSTRACT

PURPOSE: Radical lymph node dissection for right-sided colon cancer is technically challenging. No clear guideline is available for surgical resection of clinical stage I right-sided colon cancer. This study was designed to review the pathologic stage of clinical stage I right-sided colon cancer and determine the relevant extent of surgical resection.METHODS: Patients were treated for clinical stage I right-sided colon cancers (cecal, ascending, hepatic flexure, and proximal transverse colon) between July 2006 and December 2014 at a tertiary teaching hospital. Open surgery was not included because laparoscopic surgery is an initial major procedure in the institution.RESULTS: During the study period, 80 patients diagnosed with clinical stage I right-sided colon cancer were classified into 2 groups according to the pathology: stage 0/I and II/III. Tumor sizes were larger in the stage II/III group (P = 0.003). The stage II/III group had higher rates of vascular (P = 0.023) and lymphatic invasion (P = 0.023) and lower rates of well differentiation (P = 0.022). During follow-up, 1 case of local and 4 cases of systemic recurrences were found. Multivariate analysis to confirm odds ratios affecting change from clinical stage I to pathological stage II/III showed that tumor size (P = 0.010) and the number of retrieved lymph nodes (P = 0.046) were risk factors.CONCLUSION: For right-sided colon cancer, even with clinical stage I included, radical lymph node dissection should be performed for exact staging with sufficient number of lymph nodes. This will help determine appropriate adjuvant treatment, especially in large tumor sizes.

ABSTRACT

Colon cancer is very rarely accompanied by tumor thrombosis of the superior mesenteric vein (SMV). A 46-year-old patient had been diagnosed with SMV tumor thrombosis related to colon cancer without hepatic metastasis and underwent right hemicolectomy with SMV tumor thrombectomy. Tumor thrombosis was pathologically confirmed as metastatic colon cancer. There has been no recurrence for 12 months with 12 cycles of adjuvant-chemotherapy.

ABSTRACT

Pre-operative chemoradiotherapy (CRT) is a preferable treatment option for patients with locally advanced rectal cancer. However, few data are available regarding pre-operative CRT for locally advanced colon cancer. Here, we describe two cases of successful treatment with pre-operative CRT and establish evidence supporting this treatment option in patients with locally advanced colon cancer. In the first case, a 65-year-old woman was diagnosed with ascending colon cancer with duodenal invasion. In the second case, a 63-year-old man was diagnosed with a colonic-duodenal fistula due to transverse colon cancer invasion. These case reports will help to establish a treatment consensus for pre-operative CRT in patients with locally advanced colon cancer.

ABSTRACT

Eosinophilic gastrointestinal disorder (EGID) is an uncommon disease that is accompanied by intestinal eosinophil infiltration without a secondary cause of eosinophilia. Eosinophilic enteritis is a secondary portion of EGID that can present a range of gastrointestinal symptoms according to the affected depth of the intestinal layer. The subserosal type of eosinophilic enteritis presenting as ascites is relatively rarer than the mucosal type. In general, eosinophilic enteritis occurs in patients with food allergies, but its mechanism is unclear. The authors experienced a 29-year-old female patient with a large amount of ascites with diarrhea and abdominal pain. The patient was diagnosed with an influenza A infection one week earlier. Peripheral eosinophilia (absolute eosinophil count: 6,351 cells/mm³) and eosinophilic ascites (97% of white blood cells in the ascites are eosinophil) were present. Abdominal CT revealed a large amount of ascites and edematous changes in the ileum and ascending colon wall. A diagnosis of eosinophilic enteritis was confirmed as eosinophilic ascites by paracentesis, with eosinophil infiltration of the bowel wall by an endoscopic biopsy. The patient's symptoms improved rapidly after using steroids. To the best of the author's knowledge, this is the first report of eosinophilic enteritis with massive ascites after an influenza A virus infection in a Korean adult.

ABSTRACT

Actinomycosis can mask malignant diseases. This paper reports a case of colonic diffuse large B-cell lymphoma (DLBCL), which was misdiagnosed as abdominal actinomycosis. A 76-year-old woman presented with right flank pain and weight loss. Abdominal CT and colonoscopy revealed a huge ascending colon mass. Despite the initial impression of a malignancy, a colonoscopic biopsy revealed no malignant cells, but sulfur granules and a filamentous organism suggesting actinomycosis. Intravenous penicillin G was administered under the impression of abdominal actinomycosis but her condition deteriorated rapidly. Follow up CT showed markedly increased colon mass and new multiple nodular lesions around the ascending colon. Sono-guided percutaneous biopsy of the nodular lesion was performed. The pathological result was DLBCL. The patient was scheduled to undergo chemotherapy but the patient expired due to cancer progression. The diagnosis of gastrointestinal infiltrating tumors is often difficult because a superficial biopsy usually does not provide a confirmative diagnosis. This case highlights the difficulty in making a correct diagnosis of lymphoma due to the concomitant actinomycosis. Malignant conditions must be considered in cases of actinomycosis with no response to antimicrobial therapy.

ABSTRACT

Colon cancer is one of the most common malignancies of the alimentary tract, and one main metastatic route is lymph node metastasis. Thorough dissections of regional lymph nodes is one of the core surgical treatment of right colon cancer. D3 lymphadenectomy and complete mesocolic excision (CME) are generally accepted surgical methods for right colon cancer, which can improve the standardization of surgery, improve the quality of tumor resection, and provide more lymph nodes dissectal. Colon cancer of hepatic flexure is likely to have metastasis of the infrapyloric lymph nodes (No.206), which are not regional lymph nodes. Lymph node dissection of No.206 group belongs to extended right hemicolectomy, which involves many vascular variations and complicated peripheral anatomical structure. The theory of fascial surgery provides surgeons with anatomic basis and a clear understanding of the anatomical structure of the infrapyloric region, which is an important theoretical basis for the thorough dissection of lymph nodes in No.206 group, and can completely remove the mass, regional lymph nodes and adipose connective tissue, so as to achieve the goal of non-bleeding surgery. Lymph nodes in No.206 group were dissected, not just the visible lymph nodes, but the entire lymph nodes and lymphatic vessels in the region, including adipose tissue. Extended right hemicolectomy requires higher surgical techniques. The survival benefits of extended right hemicolectomy are not supported by high-level evidence. It is still controversial whether the infrapyloric lymph node dissection should become routine for colon cancer of hepatic flexure. In this article, the metastasis and dissection of infrapyloric lymph node in colon cancer of hepatic flexure is elucidated.

ABSTRACT

BACKGROUND/AIMS: Previous studies have reported that endotoxemia is associated with pathogenesis and complications in cirrhosis. Endotoxin stimulates the secretion of inflammatory cytokines, which contributes to the development of complications. In addition, endotoxin easily invades the gut barrier system because of the increased intestinal permeability due to portal hypertensive enteropathy. In this report, we explored changes in cytokine levels and intestinal permeability and measured the thickness and elasticity of the bowel wall using ultrasonography in cirrhotic patients.METHODS: We enrolled 40 patients with cirrhosis classified as Child-Pugh B or C and 20 healthy volunteers. Abdominal ultrasonography examinations were used to evaluate bowel wall parameters in the ascending colon and terminal ileum. Intestinal permeability was measured using dual sugar absorption tests with lactulose and mannitol. Levels of tumor necrosis factor (TNF)-α and IL-10 were determined from blood samples. We compared these outcomes between cirrhotic patients and healthy controls and between Child-Pugh B and C patients. In addition, we explored the correlation between cytokine levels, intestinal permeability ratio, and bowel wall parameters in cirrhotic patients.RESULTS: In cirrhotic patients, the ascending colon wall elasticity decreased (20.4 vs. 10.9 kPa, p = 0.048) and the terminal ileum wall thickness increased (4.2 vs. 1.9 mm, p < 0.001). The intestinal permeability ratio and levels of the cytokines TNF-α and IL-10 increased (0.219 vs. 0.017, p < 0.001; 22.47 vs. 13.48 pg/mL, p < 0.001; and 14.91 vs. 8.57 pg/mL, p = 0.019, respectively) in cirrhotic patients. However, there were no significant differences between Child-Pugh classes and no significant correlations between bowel wall parameters and intestinal permeability or cytokine levels.CONCLUSIONS: Ultrasonography revealed bowel wall thickening and decreases in elasticity; in addition, intestinal permeability and cytokine levels increased in cirrhotic patients compared with healthy controls.

ABSTRACT

Continuous duodenal levodopa/carbidopa intestinal gel delivery by a gastrostomy infusion system improves control of Parkinson’s disease. The overall complication rates of percutaneous endoscopic gastrojejunostomy were reported to be 41% and 59% for immediate and delayed adverse events, respectively. A 72-year-old woman underwent percutaneous endoscopic gastrojejunostomy using the delivery system noted above. Abdominal pain and vomiting occurred 3 months later. Esophagogastroduodenoscopy showed a longitudinal ulcer extending from the lower gastric body to the ileum end, with small intestinal telescoping. Colonoscopy showed a large bezoar of food residue that was attached around the tip of the tube, reaching the ascending colon, which may have acted as an anchor. Thus, the gastric antrum and small intestine were shortened with telescoping. This complication was resolved by crushing the bezoar with forceps during colonoscopy and can be prevented by consuming a fiber-free diet and periodic exchanges of the tube using esophagogastroduodenoscopy.

ABSTRACT

RESUMEN El síndrome de Waugh es una patología del neonato caracterizado por la asociación de una malrotación intestinal a una intususcepción. Existen pocos casos documentados en la literatura, lo que conlleva una baja incidencia. Presentamos el caso de un neonato femenino de 4 meses de edad quien fue llevada a tratamiento quirúrgico con oclusión intestinal y evolución posoperatoria favorable. El objetivo del trabajo es presentar el caso de un síndrome de Waugh en un lactante en cuyo cuadro se debe mantener una alta sospecha diagnostica, apoyándose con la toma de estudios de imagen complementarios ante un cuadro de dolor abdominal en pacientes lactantes cuya resolución diagnostica siempre resulta un reto para el médico. Si bien estas acciones podrán en un futuro reflejar un aumento en la incidencia de este síndrome, también es posible que el manejo de dicho síndrome se optimice. Paciente femenina de 4 meses de edad la cual fue sometida a tres intentos de desinvaginación hidrostática antes de pasar a laparotomía exploradora para corrección definitiva de su patología. La asociación de invaginación con mal rotación intestinal actualmente es subdiagnósticada, debido a la tendencia conservadora actual. Es importante realizar más estudios de imagen antes de iniciar con cualquier estrategia terapéutica, para no retrasar el manejo quirúrgico definitivo que este requiere. De esta manera se podrá ganar en la calidad de los pronósticos de los pacientes(AU)


ABSTRACT Waugh's syndrome is a neonatal pathology characterized by the association of intestinal malrotation and intussusception. There is a low number of cases documented in literature, which implies low incidence. Here is a 4 months-old female neonate who was surgically treated because of intestinal occlusion, and her postoperative recovery was favorable. The objective was to present a Waugh's syndrome case in a newborn in which high diagnostic suspicion is important, supported by complementary imaging studies when we face abdominal pain in neonates whose diagnostic resolution is always a challenge to the physician. These actions may show an increase in the incidence of this syndrome in the future; it is also possible that the management of this disease be optimized. Hydrostatic disinvagination was performed three times in this patient before undergoing exploratory laparotomy for final correction of her pathology. The association of invagination and intestinal malrotation is poorly diagnosed at present, due to current conservative tendencies. However, it is important to perform more imaging studies before adopting any therapeutic strategy to avoid delays in the definitive surgical management of this disease(AU)

ABSTRACT

<p><b>OBJECTIVE</b>To compare the difference of the diameters of superior mesenteric vein (SMV) and gastrocolic trunk (GCT) between patients with cecum-ascending colon cancer and normal individuals, and to assess the diagnostic value of the diameters of SMV and GCT in cecum-ascending colon cancer.</p><p><b>METHODS</b>Preoperative imaging data of 60 patients with primary cecum-ascending colon cancer confirmed by postoperative pathology at the First Affiliated Hospital of Sun Yat-sen University from June 2014 to December 2016 were retrospectively analyzed. The diameters of SMV and GCT were measured on preoperative CT images. SMV was measured at about 2 cm below the junction of SMV and splenic vein. GCT was measured at 1 cm near the proximal junction of right colon vein, right gastroepiploic vein and anterior pancreaticoduodenal vein. Another 60 people receiving pelvic CT examination without organ illness were collected as control. The diameter differences of SMV and GCT between cancer group and control group were compared. The diagnostic value of the diameters of SMV and GCT in cecum-ascending colon cancer was evaluated by receiver operating characteristic (ROC) curves.</p><p><b>RESULTS</b>Among 60 cases of cecum-ascending colon cancer, 36 were males and 24 were females with median age of 48 years (range 28-84); 13 were cecum cancer, 47 were ascending colon cancer; 11 had no lymph node and liver metastasis, 40 had lymph node metastasis, 9 had liver metastasis (all with lymph node metastasis). Compared to control group, the diameters of SMV and GCT in cancer group were significantly longer [SMV:(11.2±1.3) mm vs. (9.5±1.7) mm, t=6.04, P<0.001; GCT:(5.5±0.9) mm vs. (3.5±1.0) mm, t=11.51, P<0.001]. However, there were no statistically significant differences in diameters of SMV and GCT among hepatic metastasis, lymph node metastasis and no metastasis cancer groups (all P>0.05). The ROC curve analysis showed that the area under the curve of SMV diameter was 0.777, and the optimal cut-off point was 10.5 mm in the diagnosis of cecum-ascending colon cancer, with the sensitivity and specificity of 95.0%(57/60) and 46.7%(28/60) respectively. The area under the curve of GCT diameter was 0.923, and the optimal cut-off point was 4.5 mm in the diagnosis of cecum-ascending colon cancer, with sensitivity and specificity of 88.3%(53/60) and 85.0%(51/60) respectively.</p><p><b>CONCLUSION</b>The dilation of the SMV and GCT may be used as warning factors for cecum-ascending colon cancer, especially the diameter of GCT.</p>

ABSTRACT

PURPOSE: Stage-IIIC colon cancer is an advanced disease; however, its oncologic outcomes and prognostic factors remain unclear. In this study, we aimed to determine the predictors of disease-free survival (DFS) in patients with stage-IIIC colon cancer. METHODS: From a multicenter database, we retrospectively enrolled 611 patients (355 men and 256 women) who had undergone a potentially curative resection for a stage-IIIC colon adenocarcinoma between 2003 and 2011. The primary end-point was the 5-year DFS. RESULTS: The median age was 62 years; 213 and 398 patients had right-sided colon cancer (RCC) and left-sided colon cancer (LCC), respectively. The 5-year DFS in all patients was 52.0%; median follow-up time was 35 months (range, 1–134 months). A multivariate Cox regression revealed that female sex (hazard ratio [HR], 1.50; 95% confidence interval [CI], 1.19–1.90; P < 0.01), right-sided tumor location (HR, 1.65; 95% CI, 1.29–2.11; P < 0.01), lymphatic invasion (HR, 1.52; 95% CI, 1.08–2.15; P < 0.01) and a high (≥0.4) metastatic lymph node ratio (HR, 3.72; 95% CI, 2.63–5.24; P < 0.01) were independent predictors of worse 5-year DFS. Female patients with RCC were 1.79 fold more likely to experience recurrence than male patients with LCC. CONCLUSION: Female sex and right-sided tumor location are associated with higher tumor recurrence rates in patients with stage-IIIC colon cancers. Aggressive treatment and close surveillance should be planned for patients in these groups.

ABSTRACT

PURPOSE: The aim of the present study was to evaluate the usefulness of indocyanine green (ICG) as a preoperative marking dye for laparoscopic colorectal surgery. METHODS: Between March 2013 and March 2015, 174 patients underwent preoperative colonoscopic tattooing using 1.0 to 1.5 mL of ICG and saline solution before laparoscopic colorectal surgery. Patients’ medical records and operation videos were retrospectively assessed to evaluate the visibility, duration, and adverse effects of tattooing. RESULTS: The mean age of the patients was 65 years (range, 34–82 years), and 63.2% of the patients were male. The median interval between tattooing and operation was 1.0 day (range, 0–14 days). Tattoos placed within 2 days of surgery were visualized intraoperatively more frequently than those placed at an earlier date (95% vs. 40%, respectively, P < 0.001). For tattoos placed within 2 days before surgery, the visualization rates by tattoo site were 98.6% (134 of 136) from the ascending colon to the sigmoid colon. The visualization rates at the rectosigmoid colon and rectum were 84% (21 of 25) and 81.3% (13 of 16), respectively (P < 0.001). No complications related to preoperative ICG tattooing occurred. CONCLUSION: Endoscopic ICG tattooing is more useful for the preoperative localization of colonic lesions than it is for rectal lesions and should be performed within 2 days before laparoscopic surgery.

ABSTRACT

Ectopic varices are rare among patients with portal hypertension, especially in the ascending colon. It is difficult to evaluate massive lower gastrointestinal bleeding in patients with liver cirrhosis by colonoscopy due to hemodynamic instability and poor bowel preparation. In Korea, there has only been one case report about ascending colon variceal bleeding, in which hemostasis was performed by venous coil embolization. We report another rare case of ascending colon variceal bleeding in a patient with alcoholic cirrhosis, who was successfully treated via two sessions of N-butyl-2-cyanoacrylate injection through colonoscopy. This case suggests that the careful endoscopic approach and hemostasis with glue injection might be an option for treating massive bleeding in the lower gastrointestinal varix.

ABSTRACT

BACKGROUND/AIMS: Inadequate bowel preparation can result in prolonged procedure time and increased missed lesion and complication rates. This prospective study aimed to evaluate bowel preparation quality and identify the predictive factors for inadequate bowel preparation in actual clinical practice. METHODS: We included 399 patients who underwent colonoscopy between June 2015 and July 2016. Using the Aronchick bowel preparation scale, we defined a score ≤2 as adequate preparation and a score >2 as inadequate preparation. RESULTS: Mean patient age was 58.38±12.97 years; 60.6% were male. Indications for colonoscopy included screening (69.7%) and surveillance after polyp removal (21.3%). A split-dose regimen was prescribed to 55.4% of patients. The inadequate bowel preparation rate was 28.1%. Overall, the median time between the last bowel preparation agent dose and start of colonoscopy was 5.0 hours (range, 1.5–16.0 hours); that of the adequate group was 5.0 hours (range, 1.5–16.0 hours); and that of the inadequate group was 5 hours (range, 2–23 hours). The mean bowel preparation scale score of the ascending colon (1.94±0.25) was significantly higher than that of other colon segments. On multivariate analysis, elderly age, history of cerebrovascular disease, history of gastrectomy or appendectomy, and total preparation solution uptake < 2 L were the independent predictors of inadequate bowel preparation. CONCLUSIONS: The inadequate bowel preparation rate was 28.1%. Risk factors included elderly age and history of cerebrovascular disease or abdominal surgery. Patients with these risk factors require special care and education.

ABSTRACT

BACKGROUND/AIMS: Although functional abdominal pain disorders (FAPDs) are common in children, the accurate pathogenesis of FAPDs is not known yet. Micro-inflammation, particularly tissue eosinophilia of gastrointestinal (GI) tract, has been suggested as the pathophysiology observed in several GI disorders. We aimed to evaluate eosinophilic infiltration throughout the entire GI tract in children with FAPDs, compared to those with inflammatory bowel diseases (IBD) and to normal reference values. METHODS: We included 56 children with FAPDs, 52 children with Crohn’s disease, and 23 children with ulcerative colitis. All subjects underwent esophagogastroduodenoscopic and colonoscopic examination with biopsies. Tissue eosinophil counts were assessed in 10 regions throughout the GI tract. RESULTS: Eosinophil counts of the gastric antrum, duodenum, terminal ileum, cecum, and ascending colon were significantly higher in children with FAPDs compared to normal reference values. Eosinophil counts of the stomach and the entire colon were observed to be significantly higher in children with IBD than in those with FAPDs. Even after selecting macroscopically uninvolved GI segments on endoscopy in children with IBD, eosinophil counts of the gastric body, cecum, descending colon, sigmoid colon, and the rectum were also significantly higher in children with IBD than those with FAPDs. CONCLUSIONS: Significantly high eosinophil counts of the stomach and colon were observed in the order of IBD, followed by FAPDs, and normal controls, regardless of endoscopically detected macroscopic IBD lesions in children. This suggests some contribution of GI tract eosinophils in the intrinsic pathogenesis of FAPDs in children.

ABSTRACT

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.
