The applicability of laparoscopic gastrectomy in the surgical treatment of giant duodenal ulcer perforation.

Purpose: The present study aims to provide an applicability of laparoscopic gastrectomy used in the treatment of giant duodenal ulcer perforation.

Methods: Between July 2010 and April 2011, laparoscopic distal gastrectomy with ROUX-EN-Y gastrojejunostomy and truncal vagotomy was performed in consecutive 5 patients with giant duodenal ulcer perforation.

Results: There was no conversion to open surgery.

Two-day fasting prior to intestinal ischemia-reperfusion injury on bacterial translocation in rats.

Purpose: The aim of this study is to verify the effect of two-day fasting prior to intestinal ischemia-reperfusion (I/R) injury on bacterial translocation (BT).

Materials And Methods: Mail Sprague-Dawley rats were divided into four groups: group 1, control rats that underwent sham operation only; group 2, rats fasted for two days prior to sham operation; group 3, rats that underwent occlusion of mesenteric vessels for 30 min followed by reperfusion for 4 hr; and group 4, rats fasted for two days prior to the same intestinal I/R injury as in group 3. In all groups, E.

Clinical usefulness of preoperative and postoperative chest computed tomography for colorectal cancer.

Purpose: This research sought to identify the utility value of chest computed tomography (CT) when it comes to the diagnosis of lung metastasis in cases of colorectal cancer.

Methods: From September 2004 to January 2008, 266 patients who were treated for colorectal cancer at Department of Surgery, Hanyang University College of Medicine, were divided into two groups: one that underwent preoperative and postoperative periodical chest CT (periodical inspection group, PIG; May 2006 to January 2008, 135 patients) and one that did not undergo periodical chest CT (non-periodical inspection group, NPIG; September 2004 to April 2006, 131 patients) for comparison.

Results: The overall lung metastasis diagnosis rates did not manifest any significant difference.

Release kinetics and in vitro bioactivity of basic fibroblast growth factor: effect of the thickness of fibrous matrices.

In this study, we fabricated non-woven matrices using blends of polycaprolactone and gelatin with various spinning volumes to control the immobilized heparin content, which was ultimately intended to increase the immobilization efficiency of bFGF. The amount of bFGF on the heparin conjugated fibrous matrices depended on the thicknesses of the swollen matrices ranging from 35.4 ± 6.

Biofeedback therapy after perineal rectosigmoidectomy or J pouch procedure.

The aim of this study was to determine the outcome and to identify possible predictors of success for biofeedback therapy after perineal rectosigmoidectomy (PRS) or coloanal or ileoanal J pouch. A retrospective chart review of all patients with electromyography-based biofeedback therapy due to fecal incontinence after PRS or a J pouch procedure was undertaken. Follow-up was obtained by telephone survey.

A case of linitis plastica involving the entire colon, ileum, and appendix.

Linitis plastica of the colon is an uncommon presentation of primary colorectal cancer. This entity of colorectal cancer is characterized by a diffuse infiltrating tumor with desmoplastic reaction and poor prognosis. Although widespread infiltration is the main feature of linitis plastica, the tumor extending to more than 2 segments of the colon is uncommon.

Bio-artificial skin composed of gelatin and (1-->3), (1-->6)-beta-glucan.

Porous scaffolds composed of gelatin and beta-glucan were prepared using the freeze-drying method. The scaffold had an inter-connected pore structure with average pore size of 90-150 microm. Results for the contact angle and cell attachment revealed that a high gelatin content was suitable for cellular attachment and distribution in two- or three-dimensional fibroblast cultures, because the gelatin had acidic residues, and arginine-glycine-aspartic acid groups.

Clinical value of prophylactic ureteral stent indwelling during laparoscopic colorectal surgery.

One of the hazards of colorectal surgery is ureteric injury. The aim of this study was to evaluate the results of ureteric catheterization regarding its safety and operative time. One-hundred sixty two patients underwent laparoscopic segmental left or right colectomy.
