Background/aims: Although incomplete endoscopic resection of colonic neoplasms can lead to the development of interval invasive cancer, few studies have assessed clinical outcomes after histologically incomplete resection of colonic mucosal cancer. We aimed to evaluate the clinical outcomes of patients with histologically positive or uncertain resection margins after endoscopically complete resection of colonic mucosal cancer.
Methodology: We analyzed the clinical course of 38 patients (median 62 years, male:female = 27:11) who underwent endoscopically complete resection of colonic mucosal cancer, but who showed histologically positive or uncertain resection margins.
Background: The optimal colon-cleansing method after failure of bowel preparation (BP) for colonoscopy has not been established.
Aims: We aimed to compare BP rescue methods after failed initial BP and to identify risk factors for rescue BP failure.
Methods: Eighty-five patients with BP failure after 4 L polyethylene glycol (PEG) ingestion were prospectively enrolled from March 2008 to March 2012.
Purpose: To evaluate the clinical efficacy and safety of fluoroscopically guided balloon dilation for pyloric stricture associated with Crohn disease (CD) while monitoring the outcome.
Materials And Methods: Five patients (age range 15-34 y) were diagnosed with symptomatic pyloric stricture associated with CD between November 2006 and August 2009. All five patients underwent fluoroscopically guided balloon dilation one or more times.
Familial adenomatous polyposis (FAP) is an inherited disease characterized by the development of hundreds of colorectal adenomas, leading to a 100% lifetime risk of colorectal cancer. A prophylactic colectomy is recommended for patients with FAP to prevent colorectal cancer. Four surgical strategies are available for patients with FAP: proctocolectomy with permanent ileostomy, colectomy with ileorectal anastomosis, proctocolectomy with Kochs pouch continent ileostomy (Koch), and restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA).

Therefore, we assessed the relative frequency and clinical features of T-cell NHL in Korea.
Methods: We performed a retrospetcive analysis of 586 patients with NHL.
Background/aims: Diffuse large B-cell lymphoma (DLBCL) in Koreans is frequently accompanied by extranodal (EN) disease at the time of autologous stem cell transplantation (ASCT). We sought to determine whether high EN involvement affected survival following ASCT in Koreans.
Methods: We reviewed 27 patients who had DLBCL with residual disease at ASCT: 13 with residual disease at nodal site(s) only and 14 with nodal and EN disease.
Background: Granulocyte-colony-stimulating factor (G-CSF) is used to enhance hematopoietic recovery after autologous stem cell transplantation (ASCT). Recommendations for administration of G-CSF during the engraftment phase of ASCT have recently changed. This study sought to compare the early engraftment profile between groups receiving single-dose versus split-dose lenograstim to enhance engraftment after ASCT.

Background: Although high dose chemotherapy coupled with an autologous stem cell transplantation (ASCT) is widely accepted as effective therapy for multiple myeloma (MM), few reports are available in Korea, especially in the area of double ASCT. We present the results of an institutional retrospective study of 12 patients with MM treated by double ASCT.
Methods: Eligible patients received induction therapy using vincristine, adriamycin, dexamethasone (VAD), and mobilization was performed using cyclophosphamide plus lenograstim.
