Dentocutaneous fistula of the face neck is an infrequent manifestation of chronic dental infection. A periapical dental abscess may be initiated by disease, trauma, or thermal or chemical injury and develops into an extensive necrosis of surrounding tissue. Diagnostic errors can result in multiple excision, biopsies, and ineffective long-term antibiotic therapy. Awarness that periapical dental abscess is the most common etilolgic factor of cutaneous sinus tracts involves the face & neck will facilitate their early diagnosis and prevent needless treatment or anxiety for the patient. From 1994 to 1998, we have performed 6 cases of dentocutaneous fistula. Among of them, three were men and the others were women, age ranged from 18 to 66-year-old, and morbidity period was from 3 weeks to 3 years, the follow-up period ranged from 5 to 18 months (mean period 11 months). In conclusion, an understanding of the pathogenesis of cutaneous fistulae arising from dental infections will lead to proper early diagnosis and treatment without unnecessary surgery.

This article consists of a clinical analysis of 221 cases of the Pediatric Inguinal Hernia treated in General Surgery of Pusan Adventist Hospital, from January 1990 to June 1996. The results were as follows ; 1) Patients with inguinal hernia were 37.5% of total operative patients in the division of pediatric surgery 2) Males predominated over females by the ratio of 5.5:1 3) Of 221 cases, 101(54%) were on the Rt side, 80(43.1%) on the Lt side and the remainder (6.4%) on both side in case of Male. 20(58.8%) were on the Rt side, 13(38.2%) on the Lt sid and the remainder (3.0%) on both side in case of Female. 4) The chief Complaints were inguinal protrusion in 131 cases(59.3%) and scrotal enlargement in 77 cases(34.9%) 5) Peak incidence age (32 Months) & Duration of history (20.2 Months) 6) Associated diseases were found in 10 cases(4.9%) and they were cryptorchidism (1.47%), hydroclele (0.98%), Umbilical hermia (0.49%), Heart anomaly (0.49%), cleft palate (0.49%), Teratoma (0.49%), and Jejunal atresia (0.49%). Family History was denied. 7) All were indirect hernia. 8) Incarcerated cases were 6(2.7%) and the ratio of male to female was 2:1, and the location of incarcerated hernia was Rt (66.6%), and Lt (33.3%) 9) There were 70 cases of strangulation. 10) Intraperitoneal organ in hernial sac was noted in 5 cases (2.26%), and they were ovary and fallopian tube in 3 cases (1.35%), small intestine in 1 case (0.45%), cecum and appendix in 1 case (0.45%). 11) 215 (97%) of all hernia were repaired only by highligation of sac and 6(3%) were inforced with Bassini's posterior wall repair. 12) Mean postoperative hospitalization were 5.2 days. 13) Postoperative complications occured in only 2 cases : hematoma and edema 1, wound infection 1.

PURPOSE: We report seven cases of pancreas transplantation, first performed in Korea, in the context of postsurgical radiologic studies. MATERIALS AND METHODS: All patients with insulin-dependent diabetes mellitus received transplants from cadevaric(n=6) or living related donor(n=1). Retrospective analysis of 27 US(including 19 Duplex US), two CT, four MRi, and three scintigraphy for these patients was made with surgico-pathological correlation in five cases. RESULT:Of the seven patients, three-month graft survival was five and one-year survival was two. One patient died of abdominal abscess following surgery. US gave the valuable informations regarding the graff swelling, vascular complication, and perigraff fluid collection. RBC bleeding scan was effective of the presence or absence and location of intestinal bleeding. CT was useful in determining the extent and severity of the pancreatitis. MRI gave a little information about functional status of the grafted pancreas. CONCLUSION: The choice of appropriate imaging modalities for postsurgical work up in patients who had pacreas transplantation depends on the clinical conditions of the patients and complications suspected. Further prospective studies appear to be necessary to eatablish the interval and modality choice for early detection of the complication.

PURPOSE: It may be difficult to differentiate renal cell carcinoma involving collecting system from renal urothelial tumor invading into renal parenchyma. The purpose of this study was to assess the differences of CT findings between two conditions. MATERIALS AND METHODS: CT findings of 5 cases of renal cell carcinoma involving the renal collecting systems and 10 cases of renal urothelial tumors invading the renal parenchyma were compared, and analyzed about the presence or absence of hydronephrosis, normal or abnormal CT nephrogram, renal contour changes due to mass and tentative diagnosis. The diagnoses were confirmed at surgery. RESULTS: Renal cell carcinoma showed hydronephrosis in only 20% and normal CT nephrogram and outward contour bulging in all cases. In contrast, renal urothelial tumor showed hydronephrosis(70%), abnormal CT nephrogram(60%), and preservation of reniform shape(100%). CONCLUSION: Renal contour changes and CT nephrogram may be useful in distinguishing both disease entities.

PURPOSE: To assess the role of the preoperative portal vein embolization (PVE) in patients in need of major hepatectomy. MATERIALS AND METHODS: Total of 11 cases consisted of Klatskin tumor (n:6), gallbladder cancer (n=2), and hepatocellular carcinoma (n=3). After percutaneous transhepatic puncture of portal vein (right:7, left:4), the embolization of 1st order branch of right portal vein was done with Gentamicin soaked Gelfoam cubes. Radiologically, the angle between the middle hepatic vein and the inferior vena cava was measured on pre- and post-PVE CT (F/U :10 days) to evaluate the hypertrophy of the left lobe. Clinically, amount and nature of the drained bile through the PTBD tube of both lobes were analyzed in 5 patients with Klatskin tumor. The interval between PVE & operation was 10-24 days. Operative findings & the changes of postop. total bilirubin were analyzed and the complication after procedure was checked. RESULTS: There was decrease in mean angle between the middle hepatic vein and the inferior vena cava from 35.9 degree to 23.9 degree, but it was insignificant statistically (p=0.09). The embolization of right portal vein was done and there was increase in amount of drained bile from the nonembolized left lobe by 2-3 folds 8-14 days after PVE. The color and consistency between both lobes were significantly different; right lobe was darker in color and softer in consistency. Postoperative total bilirubin increased by 2-3 folds 1 to 4 days after PVE and normalized 10 to 14 days after PVE. Most of the patients had mild abdominal pain and fever after PVE and 1 patient had localized hematoma at puncture site which was subsided spontaneously. CONCLUSION: The preoperative portal vein embolization is a useful method for minimizing postoperative liver failure in patients in need of major hepatectomy.

PURPOSE: To evaluate the morphological differences between malignant and inflammatory lesions that arise from the cecal or pericecal region on CT by analyzing not only the mass itself but also the changes of surrounding structures. SUBJECTS AND METHODS: We reviewed CT scans of 38 cases of cecal lesions confirmed by pathology(16 malignant lesions and 22 inflammatory lesions). The analytical points were :the changes of bowel wall mass, the changes of surrounding structures, strands of retroperitoneal fat, pericecal fluid collection, and regional lymphadenopathy. RESULTS: The malignant bowel wall thickening(18.0mm) was thicker than inflammatory one(ll.4mm)(p < 0.001). Concentric bowel wall thickening was seen in 87.5%(14/16) of malignant lesions and 36%(8/22) of the inflammatory lesions. The pericecal fat stranding was circumferential in 84%(16/22) of inflammation and eccentric in 64%(916) of malignancy(p < 0.01). Pericolic fat infiltration was more extensive in inflammatory lesions(p < 0.005). The strands of retroperitoneal fat were more frequently found in inflammatory lesions(p < 0.05). The pericecal fluid collection was seen in 55%(12/22) of inflammatory lesions and none of malignant lesions. There was no difference in the presence of pericecal lymphadenopathy between the two groups. CONCLUSION: Malignant cecal masses have thicker and concentric bowel wall thickening, and narrower and eccentric pericolic fat infiltration. On the other hand, inflammatory masses have relatively thinner and eccentric bowel wall thickening, and more extensive and circumferential pericolic fat infiltration sometimes accompanied by abnormal fluid collection.

BACKGROUND: The purpose of this study was to estimate the economical impacts of surgical site infection (SSI) after general surgeries. METHODS: A prospective study was performed with the surgeries from September to December, 2002 and the SSI cases were collected based on the definitions of Centers for Disease Control and Prevention, The length of stay (LOS) and the hospital charge for the SSI group were compared with the non-SSI (NSSI) group by a matched cohort study for age, sex, operation procedure, and NNIS risk groups. RESULTS: There were 1,007 cases of surgeries and the 52 cases of SSI and the 26 cases have been matched. The LOS of the SSI group was 5.2 days longer than that of the NSSI group (P<0.05) which was significant, The injection and dressing meal, and total hospital charge were \157,562, \72,251, and \2,153,964 more in SSI group than those of NSSI group (P<0,05) for post-operation stay. The charge of medication and room in SSI group were \558,146 and \723,114 more than those of the NSSI group, but there were no significant difference. CONCLUSION: The SSI could increase the LOS and the hospital charge; therefore, this economic loss had an impact on the hospitals as well as the patients. To estimate the economic impacts of SSI precisely, however, further studies are needed to analyze and control other factors for the cost such as a type of surgery. In addition, the scope and setting of cost analysis should be expanded into the aspects of an individual, the hospital, and society.
