On the contrary to congenital anomalies of intestinal rotation in pediatric patients, those in adults are generally nonsymptomatic and of little consequence. Occasionally, however, an adult may have midgut nonrotation and complain of chronic or recurrent abdominal pain. Intestinal nonrotation can be divided into complete or partial failure of rotation and into abnormalities affecting the proximal segment, the distal segment or both. We report herein a 43-year old female patient with symptomatic partial, cecocolic nonrotation.

Spinal fusion has performed for instability and anatomical reconstruction since 1985 by Barthe. Bone grafts and synthetic materials has been used for spinal fusion, but they have several limitations and complications. Recently a new synthetic polymer B.O.P.(Biocompatible Osteoconductive Polymer) was developed and it overcome the limitations of other materials. The B.O.P. showed no foreign body reaction and gave scaffolding for the osteoconduction and osteointegration. Authors operated 35 cases of spinal fusion with B.O.P. and the results and literature reviews were discussed.

Anterior interbody fusion has used for instability and anatomical reconstruction in various cervical diseases since 1958 by cloward. Bone grafts such as autograft, allograft, xenograft and synthetic materials were utilized in fusion as a graft material. But conventional fusion materials have problems including postoperative morbidity, transmission of diseases, foreign body reaction, collapse, prolongation of operation time. A new synthetic material, Biocompatible Osteoconductive Polymer(B.O.P) is developed and it was useful for cervical anterior interbody fusion as a substitute for other fusion materials.

BACKGROUND: It is controversial whether the delay of surgery for acute appendicitis by physician results in higher morbidity. Our present study explores this problem of physician delay on the postoperative outcome of patients with acute appendicitis. MATERIAL AND METHODS: Among 432 patients admitted for the presumptive diagnosis of acute appendicitis between Jan., 1995 and Dec., 1997, 358 patients with pathologically proven acute appendicits were analyzed. Physician delay from the hospital admission to the surgery was evaluated in relation to the stage of the disease at operation and postoperative outcome. RESULTS: Postoperative complications occurred signifficantly higher in advanced appendicitis group, than in simple appendicitis group. Postoperative oral consumption started significantly later and hospital days are significantly prolonged in those group. Both patient and physician delays significantly affect the stage of the disease. The finding that physician delay correlated with the stage, however, was denied by multivariate analysis. CONCLUSION: On the contrary to the patient delay, physician delay does not affect the stage of the acute appendicitis nor lead to increased incidence of postoperative complication. Physician delay to clarify the diagnosis is a reasonable strategy and it does not affect the outcome adversely.

BACKGROUND/AIMS: The mortality after pancretoduodenenctomy is decreased to less than 5 % in centers with experience. The morbidity, however, still remains high although the decrease has also been demonstrated. The aim of this study was to identify risk factors responsible for major complications following pancreatoduodenectomy. METHODS: Various features of forty nine consecutive patients who underwent pancreatoduodenectomy from 1990 to 1999 were statistically analyzed to determine risk factors for major postoperative complications. Anastomotic leakages, intraabdominal hemorrhage and intraabdominal abcess were categorized as major postoperative complication. RESULTS: In our series, postoperative mortality and morbidy rate were 6.1% and 51.0%, respectively. Seventeen major complications were found in 14 patients(28.6%): 7 cases with pancreaticojejuostomy leakage, 4 cases with biliojejunostomy leakage, 3 cases with intraabdominal hemorrhage and 1 case with intraabdominal abcess. The statistical analysis revealed that episode of intraoperative hypotension was the only independent risk factor for major postoperative complication.(Odds ratio: 25.4849, p=0.0048) CONCLUSION: Careful intraoperative management for maintenance of adequate blood pressure in hemodynamically unstable patients is important to reduce major complications after pancreatoduodenectomy.

BACKGROUND: Carinoma arising from the choledochal cyst is rare but well known complication, the mechanism of which is, however, still unclear. This study is intended to analogize the mechanism of carcinogenesis in choledocahl cyst from the changes in the cyst epithelium according to the age groups. MATERIALS AND METHODS: This retrospective study included 19 cases of choledochal cysts and was performed by comparing 6 cases of group I patients(age less than 20) to 13 cases of group II patients(age 20 or more).The records of both group patients were reviewed for demographic and clinical features. Histopathologic findings and immunoreactivities for p53 were comparatively analyzed. RESULTS: In group I, epithelial changes of chronic inflammation, regeneration atypia, hyperplasia, intestinal metaplasia and dysplasia were found in 6, 4, 5, 1 and 3 cases, respectively. In group II, there were 12 chronic inflamation, 5 regeneration atypia, 7 hyperplasia, 1 intestinal metaplasia, and 11 dysplasia including 4 high grade and 7 low grade dysplasia. There were also 3 carcinomas arising from the cyst in group II. p53 immunoreactivities were only found in those with dysplasia and carcinoma. CONCLUSIONS: Intestinal metaplasia presents in only 2 cases. On the other hand, dysplasia is one of the predominant findings in the epithelium of the cysts. These findings suggest carcinogenesis in choledochal cyst presumably follow de novo pathway(repeated injury/regeneration - dysplasia - carcinoma) rather than metaplasia - dysplasia - carcinoma sequence.
