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.

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.

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.

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.

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.

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.

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.

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.

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.
