All clinical studies reported in the literature have indicated that non-operative treatment is the treatment of choice for the diaphyseal fractures of the clavicle. It has also been suggested by some that open reduction may contribute the development of nonunion. From 1985 to 1989, 23 of 133 diaphyseal fractures of the clavicle were treated by open reduction and internal fixation with the intramedullary pinning with or without cerclage wiring, or prebent plate and screw fixation with supplementary iliac bone graft in each instance. All fractures healed without any complication such as the infection, pin migration, other fixation failure, neurovascular accident, and pseudarthrosis. Based on our experience and review of the literature, we concluded that the indications for open reduction and internal fixation should be: 1. The patient's inability to tolerate prolonged immobilization or recumbency in multiple injury. 2. Widely distracted or displaced fractures in adults. 3. Comminution with one or more large butterfly fragments. 4. Neuro-vascular compromise due to displacement and impingement of the bone fragment. 5. Symptomatic delayed union or nonunion. 6. Refracture. And early operative treatment is safe, reliable and provide excellent results comparable to the conservative treatments.

Intramedullary nailing has become the most popular fixation method in the treatment of the shaft fractures of long bones especially of tibia and femur because it affords most rigid fixation of fracture via closed method which makes early rehabilitation possible. Nowadays intramedullary nailing of the humeral shaft is being performed by many surgeons with good results. Newer implants and better surgical techniques are being developed, which suggests application of this method can be widened. Purpose of this study was aimed to define whether intramedullary nailing could be an effective method or not in the treatment of humeral shaft fractures by documenting the practical points in the application of intramedullary nailing of humerus, effectiveness in fracture healing, any complications or obstacles. We managed thirteen humeral shaft fractures with closed locked intramedullary nailing with distal fanning devices(Seidel nail) from March 1993 to April 1994. Average follow-up period was 14 months(12 months-18 months). The results were as follows; 1, Union of the fracture was obtained at average 12.9 weeks(9 weeks-20 weeks) postoperatively except one case of nonunion, in which case, union was obtained at postoperative 10 months finally. 2. Among the 13 cases, painful limitation of shoulder motion remained in 6 cases. This complication was more common in the cases with protruded proximal end of the nail. Above results suggest that locked intramedullary nailing seemed to be one of the useful method in the treatment of the humeral shaft fractures. However, destruction and irritation of shoulder by the nail was found to be a grave problem, and we found that further investigations should solve this problem.

The purpose of this study was to investigate the morphologic changes of the bile canaliculi and its associated structures of the liver induced by common bile duct ligation(CBDL) in the rat. The canalicular surface and lateral surface of the dry-fractured hepatocytes was studied with scanning electron microscopy at 1~6 weeks post ligation. The first week after CBDL, the bile canaliculi were dilated. The microvilli were increased in number and the lumens contained granular materials After 2 weeks or more, the bile canaliculi were dilated to a variable degree, and with irregularity, measuring from 1.5 to 5 micrometer in diameter, and in the advanced stage, the canaliculi showed blunting and the disappearance of microvilli. Some canaliculi had sprouting side branches. At 4~6 weeks post-ligation, the lateral surface of the hepatocytes also showed some irregularity and a tortuous appearance, and numerous small sized microvillous projections were formed. The tubular structures of the proliferated SER distributed adjacent to the lateral surface of the hepatocytes, and the direct connection of a tubular structure and the cytoplasmic membrane was observed. These results suggest that the deformity and loss of microvilli of bile canaliculi reflect the disturbance of bile secretion from the hepatocytes. And prolonged obstruction of bile flow may result in bile excretion via the lateral surface of hepatocytes.

PURPOSE: The differentiation between renal cell carcinoma(RCC) and transitional cell carcinoma(TCC) is important due to the different methods of treatment and prognosis. But occasionally it is difficult to draw a distinction between the two diseases when renal parenchyme and renal collecting systems are invaded simultaneously. MATERIAL AND METHOD: We reviewed CT scans of 37 cases of renal cell carcinoma and 12 cases of transitional cell carcinoma which showed involvement of renal parenchyma and renal sinus fat on CT. Retrospective analysis was performed by 3 abdominal radiologists. Check points were renalcontour bulging or reniform shape, location of mass center, intact parenchyme overlying the tumor, cystic change, calcification, LN metastasis, vessel invasion, and perirenal extention. RESULT:There were renal contour bulging due to the tumor mass in 33 out of 37 cases of renal cellcarcinima, wherea and nine of 12 cases of transitional cell carcinoma maintained the reniform appearance. This is significant statiscal difference between the two(p<0.005). Center of all TCCs were located in the renal sinus, and 24 out of 35 cases of RCC were located in the cortex(p<0.005). Thirty-six out of 37 cases of RCC lost the overlying parenchyma, whereas 4 out of 9 cases of well enhanced TCC had intact overlying parenchyma(p<0.005) RCC showed uptic change within the tumor mags in 31 cases which was significanity higher than the 4 cases in TCC(p<0.05). CONCLUSION: CT findings of renal cell carcinoma are contour bulging, peripheral location, obliteration of parenchyma, and cystic change. Findings of transitional cell carcinoma are reniform appearance, central location within the kidney, intact overlying parenchyma, and rare cystic change.

Endoscopic papillectomy (EP) has been considered to be a less invasive, alternative therapy to surgery for ampullary adenoma. However, complication rates after EP could not be ignored, when compared to endoscopic resection for gastrointestinal lesions. Among them, the prevalence of postpapillectomy pancreatitis is higher in EP than ERCP. The prophylactic placement of a pancreatic stent has been reported to decrease the risk of pancreatitis after EP. However, since pancreatic stent placement after EP is not always successful, various novel techniques have been developed to ensure reliable stent placement. Despite the recent advances in EP, a prospective, randomized, controlled study with a larger number of patients is needed to assess the efficacy of pancreatic stent placement to prevent pancreatitis.
