1.A Case of Duodenal Leiomyosarcoma.
Korean Journal of Gastrointestinal Endoscopy 1995;15(3):531-537
Leiomyosarcoma of small intestine is an uncommon tumor, comprising less than 20 percent of all primary malignant tumors of small intestine. Duodenal leiomyosarcoma is rare disease which amount to about 20 percent of all small bowel malignancy but potentially curable tumors often diagnosed at an advanced age, so its five-year survival following resection approximates 50% in reported series. Recently, several cases of leiomyosarcomas of duodenum were diagnosed by hypotonic duodenograhy in Korea. We experienced a woman with duodenal leiomyosarcoma that was diagnosed by endoscopic duodenal biopsy and received currative resection of the tumor(Whipple's operation). We report the case with review of the literatures.

PURPOSE: To compare standard laparoscopy-assisted Billroth I gastrectomies including standard lymph node dissection (LABIG) with hand-assisted laparoscopic surgery with the HandPort system (HALS) for the removal of early gastric cancers (EGC). METHODS: A prospective study was performed on 26 patients of EGC at Ewha Womans University Mok-Dong Hospital from July 1999 to August 2001. Seventeen patients (Group L) received LABIG using conventional laparoscopy-assisted methods and 9 patients received LABIG using HALS (Group H). We used staplers for the anastomosis, and a standard D2 lymph node dissection was done with ultrasonic shears or electrocautery. RESULTS: In group L, pathologic reports revealed 14 EGC (stage IA 14 cases), and 3 pm cancers (stage IB 1 case, II 2 cases). In group H, there were 9 early gastric cancers (stage IA 8 cases, IB 1 case). Significant differences (P<0.05) were present between group L and H in regards to the number of harvested lymph nodes (30.8 vs 18.9), estimated blood loss (462.1 vs 286.7 ml) and postoperative transfusion amounts (0.59 vs 0 unit). There were no differences in the mean operating time, distance from the lesion to the resection margin, postoperative leukocyte count, frequencies for pain control, wound size, time to diet, weight loss, serum protein, and postoperative hospital stay. Complications were present in 1 case in group L (enterocutaneous fistula) and 1 case in group H (gastric atony). There was one conversion to open surgery in group H. CONCLUSION: LABIG including standard lymph node dissections with both standard laparoscopic surgery and HALS were performed with equal outcome. The choice of surgical method depends on the characteristics of the lesion and the patient's physical factors.

Severely worn dentition causes various complications such as loss of tooth structure, discoloration, pulp complications and loss of function and aesthetics. In this case, the patient showed particularly severe attrition in the anterior teeth and lack of space for restoration. The amount of vertical dimension was determined based on the diagnostic wax up, and the patient’s adaptation was evaluated by using a removable occlusal splint for 6 weeks. Thereafter, the coordination of the muscular nervous system, aesthetics, temporomandibular joint were re-evaluated for 3 months by restoring the fixed provisional restoration. Through the above treatment process, the final restoration was completed with full mouth fixed prosthesis using monolithic zirconia, and functionally and aesthetically stable results were obtained.
