Reduction of displaced diaphyseal fractures of the radius and ulna in adult must be nearly anatomical for restoration of mormal function. Most of the fractures require operative management, and various methods of open reduction and internal fixation have been recommended. Because we believe that anatomical reduction followed by rigid internal fixation provides the most satisfactory results for these injuries, dynamic compression plating method is frequently used in our hos pi tal. We studied 52 diaphyseal fractures of the forearm bone in 33 patients treated at the S.R.C.H. from May 1980 to December 1985. Of the 33 patients, 20 had fractures of the radius and ulna; 6, fractures of the radius only; and 7, fractures of the ulna only. The fractures of both bones were treated with plate and screws in 19 patients. In another one, the ulna was treated with plate and screws and the radius was treated by screw fixation only. The results were as follows: l. Of the 52 fractures, 51(98.1%) were united after the initial operation within 23 weeks. 2. The average time for radiological union of the fracture, excluding those complicated by infection or non-union, was 11.1 weeks for 24 radii and 10.9 weeks for 25 ulnae. 3. Only one patient(3.0%) was complicated by infection and only one(1.9%) non-union of radius occurred. 4. The functional results were excellent or satisfactory in 25 patients(83.3%). 5. We have found that in adults the auto compression plating is a successful method for the diaphyseal fractures of the forearm.

While overtreatment in medical services had been the topic of interest among the medical community for a long time, there are numerous academic papers concerning over-diagnosis nowadays. The use of imaging studies for screening might lead to over-diagnosis of small renal masses (SRMs) therefore the incidence of kidney cancer increased 5 times higher than that of mortality in Korea between 2000 and 2011. The best treatment for SRMs had been debated and the present strategies include surgery, local treatment, and active surveillance. Competing risks to mortality should be considered to determine initial management strategies, and a period of initial active surveillance in patients with SRMs is safe. Tumor growth rate is the primary driver for delayed intervention of SRMs patients, and the risk of metastasis on active surveillance for SRMs is 1%–2% at 2-year follow-up.

Synovial sarcoma is a malignant soft tissue tumor that primarily occurs in the paraarticular regions, especially in the knee. They are composed of keratin-positive epithelial cells and vimentin-positive spindle cells. We report a 76 year old woman with a primary synovial sarcoma in the mediastinum that had severe adhesion to the right side of pericardium. Primary synovial sarcoma in the mediastinum is extremely rare and this is the first case reported in the Korean literature. The mass including the pericardium was resected and the defect was closed with Gore-Tex patch. The patient is well and free of disease 6 months after the operation.

Radical antegrade modular pancreatosplenectomy (RAMPS) is regarded as a reasonable approach for margin-negative and systemic lymph node clearance in left-sided pancreatic cancer. We present a patient with more than 5 years disease-free survival after robotic anterior RAMPS for pancreatic ductal adenocarcinoma in the body of the pancreas. The distal part of pancreas, soft tissue around the celiac trunk, and the origin of splenic vessels was dissected with the underlying fascia between the pancreas and adrenal gland. Resected specimen was removed through small vertical abdominal incision. Robot working time was about 8 hours, and blood loss was about 700 mL without blood transfusion. He returned to an oral diet on the postoperative first day and recovered without any clinically relevant complications. There was no lymph node metastasis, perineural or lymphovascular invasion. Both the pancreatic resection margin and the tangential posterior margin were free of carcinoma. The patient received only postoperative adjuvant radiotherapy around the tumor bed. The patient has survived for more than 5 years without evidence of cancer recurrence. Minimally invasive radical left-sided pancreatectomy with splenectomy may be oncologically feasible in well-selected pancreatic cancer.

Spinal cord ganglioglioma is an extremely rare tumor. Authors present a 6-year old boy who had a holocord ganglioglioma with a long history of kypho-scoliosis. The mass was located entirely in the spinal cord and mixed cystic and solid with variable consistencies. The color was grayish purple-yellow in soft part, and pale yellow-white in scirrhoid part. It was not well demarcated by surrounding normal spinal cord in major parts.

PURPOSE: We would like to assess the safety and feasibility of extended spleen-preserving distal pancreatectomy with segmental resection of both splenic vessels (SPDP-SRSV) in patients with large, benign and borderline malignant pancreas body tumors. METHODS: We encountered seven extended SPDP-SRSV cases from January 2006 to March 2010. Among them, three were excluded due to combined pylorus-reserving pancreaticoduodenectomy (PPPD). For the extended surgical technique, the pancreas was divided above the confluence of the superior mesenteric vein-splenic vein-portal vein (SMV-SV-PV), and vascular control was achieved at the origin of the splenic artery and the junction of the splenic vein with the SMV. The segments of both splenic vessels were then extracted along with the specimen. RESULTS: All the patients were female with a median age of 57 years (range: 24~70 years). The median tumor size was 5.5 cm (range: 5~11 cm), the median operation time was 362 minutes (range: 337~441 min), the median estimated blood loss was 150 ml (range: 50~300 ml) and the median hospital stay was 9 days (range: 7~20 days). One patient underwent robot-assisted extended Warshaw procedures. No mortality was noted, but one partial intestinal obstruction occurred and this was resolved with conservative management. On the recent follow-up, the CT scans showed no evidence of tumor recurrence or spleen infarction, but newly developed perigastric varix was noted, but it was without variceal bleeding. CONCLUSION: SPDP-SRSV with division of the pancreatic neck portion above the confluence of the SMV-SV-PV in patients with large, benign and borderline malignant pancreatic body tumors appears to be an ideal approach because of the expected long-term survival and preserving the role of the spleen.

PURPOSE: To investigate the effect of patient and tumor factors on the degree of tumor necrosis and the effect of the degree of the tumor necrosis on the survival in patients treated with curative resection following transcatheter arterial therapy. MATERIALS AND METHODS: 90 patients diagnosed as having hepatocellular carcinoma and treated with curative resection following transcatheter arterial therapy at Yonsei Medical Center between January 1986 and December 1995. The subjects were classified into four groups: 100% necrosis group (Group I, n=29), over 95% necrosis group (Group II, n=28), 50-95% necrosis group (Group III, n=13) and below 50% necrosis group (Group IV, n=20). The factors which affect on the necrosis of the tumor were compared. The overall and disease-free survival rates according to the degree of tumor necrosis were illustrated. RESULTS: There was no statistical difference in the degree of the tumor necrosis according to age, sex, HBsAg, g-FP, liver cirrhosis, tumor size and morphological classification. In the comparison between the preoperative transcatheter arterial therapies, however, transcatheter arterial chemo-oily embolization (TACOE), which used the injection of the mixture of 3 10 cc Lipiodol and 30-50 mg Adriamycin followed by Gelfoam em- bolization, showed the higher number of 100% necrosis and over 95% necrosis cases. The 1, 3 year overall survival rates were greater for Group I, although not statistically significant. The 1, 5 year disease-free survival rates were greater for Group I, although not statistically significant. CONCLUSION: In the preoperative transcatheter arterial embolization, TACOE was most effective to get total necrosis of tumor. However overall survival and disease free survival were not affected by the amount of tumor necrosis.
