PURPOSE The aim of this study was to investigate the incidence and spectrum of malignant tumors in Korean neurofibromatosis type 1 (NF1) patients. METHODS We retrospectively reviewed 125 patients who were diagnosed with NF1 at a single institution from 1995 to 2010. The incidence, location, histologic type, and radiologic findings of malignant tumors as(More)
PURPOSE The aim of this study was to observe the clinical features of a bezoar-induced small bowel obstruction and to investigate the role of abdominal computed tomography (CT) in establishing the diagnosis. METHODS We retrospectively reviewed 20 cases of bezoar-induced small bowel obstruction in our hospital from 1996 to 2010. RESULTS Thirteen patients(More)
Multiple jejunalgastrointestinal stromal tumors (GISTs) were found in a 52-year-old woman with a history of neurofibromatosis type 1. These tumors were composed of interlacing fascicles of uniform spindle cells with eosinophilic cytoplasm. Immunohistochemically, the tumor cells were positive for CD117, CD34 and negative for S-100, smooth muscle actin.(More)
PURPOSE This study evaluated the efficacy of neoadjuvant chemotherapy combining 5-flurouracil/folinic acid with irinotecan (FOLFIRI) in colorectal multiple liver metastases regardless of resectability. METHODS Forty-four patients with multiple (at least two) colorectal liver metastases were enrolled at seven tertiary referral hospitals between May 2007(More)
PURPOSE Surgical site infection (SSI) is one of the most common complications that can occur after stoma closure. Reports have described differences in the incidence of wound infection depending on the skin closure technique, but there is no consensus on the ideal closure technique for a stoma wound. The aim of this study was to compare the incidence of SSI(More)
We report a case of colonic metastasis from ovarian cancer presented as an intraluminal fungating mass mimicking primary colon cancer 8 years after surgery for ovarian cancer. A 70-year-old woman presented with constipation. She had undergone an extended total abdominal hysterectomy with bilateral salpingo-oophorectomy for an ovarian papillary serous(More)
We report a case of a goblet-cell carcinoid tumor of the appendix which metastasized to the peritoneum and was treated by using cytoreductive surgery (CRS) with intraperitoneal chemotherapy. A 47-year-old male presented with chronic constipation and was diagnosed as having a rectal adenocarcinoma with a signet-ring-cell component under colonoscopy. Computed(More)
PURPOSE Chemotherapy-induced nausea and vomiting (CINV) have a negative impact on patients' quality of life and frequently pointed to as a major factor for treatment abandonment. Serotonin (5-HT3) receptor antagonist is considered as key treatment for CINV. Ramosetron and palonosetron are recently developed 5-HT3 receptor antagonists and known as more(More)
PURPOSE Adult intussusception is uncommon, but an organic lesion is found to be the lead point in 75% to 90% of the cases. This study was designed to review our experience with adult intussusception and to determine if there are any preoperative predictive factors for a malignant lead point. METHODS Thirty-three patients over 15 years of age were(More)
