The major cause of early dislocation after total hip arthroplasty is malposition of acetabular cup. Therefore, radiographic evaluation of acetabular cup placement is essential in determining the postsurgical prognosis. The purpose of this study was to establish principles which would aid in checking the radiography. We evaluated 33 patients who were treated with total hip arthroplasty between Jan. 1988 and Aug. 1993 and investigated the methods of measuring the position of the acetabular cup on radiography using pelvic skeleton and acetabular cup. The results were analyzed as followings. l. After the total hip arthroplasty, the inclination of the acetabular cup shows average 37.1 degress in pelvis AP, 36.4 degrees in hip AP and 43.4 degrees in femur AP. This result means that the more X-ray beam focus is far from the acetabular cup, the more inclination of acetabular cup on radiography is incerased. 2. After the total hip arthroplasty, the difference of acetabular cup angle between pelvis AP and hip AP is average 0.7 degree, 6.4 degrees between pelvis AP and femur AP and 7.1 degrees between hip AP and femur AP. This result means that the more X-ray beam focus is far from acetabular cup, the larger difference between acetabular cup angle on radiography is.3. In experimental study with pelvic rotation, acetabular cup angle on radiography is average 45.7 degrees in neutral position, 42.8 degrees in 10 degree rotation, and 39.6 degrees in 20 degree rotation. This result means that the more rotation of pelvic bone is increased, acetabular cup angle on radiography is reversely diminished. 4. In experimental study with pelvic flexion-extension, acetabular cup angle on radiography is average 45.7 degrees in neutral position, 56.4 degrees in 20 degree pelvic flexion, and 32.3 degrees in 20 degree pelvic extension. This result means that when the pelvis is flexed, acetabular cup angle on radiography is increased, and when the pelvis is extended, acetabular cup angle is decreased than normal acetabular cup angle. 5. In experimental study with X-ray beams, acetabular cup angle on radiography is average 45.7 degrees in pelvis AP, 45.5 degrees in femur AP and 50.4 degrees femur AP. This result means that the more X-ray beam focus is far from acetabular cup, the more inclination of acetabular cup on radiography is increased. As the result of the study, radiographs which focus centered on hip demonstrated a nearly true representation of acetabular cup angle.

The hook-nail deformity after finger tip amputation is very common problem. This usually occurs after loss of part of the distal pulp, phalanx, and nail bed. This deformity for some patients is a trivial lesion and may be ignored, but it may be of great cosmetic significance or disabling with regard to certain occupations to the others. To correct the deformity, it is necessary to release volarly displaced nailbed, return it to its normal position, and provide adequate support to maintain correction by a carefully planned "antenna" procedure. Deformed nail is removed, tethered pulp is freed from distal phalanx, and then full thickness of the nail bed is elevated and splinted with multiple small Kirschner wires in a straight position like antennae. The coverage of defect created is done by cross finger flap. The knowledge of anatomy and physiology of nail and sorrunding structures is important to obtain good results and reduce secondary deformities. Two cases of antenna procedures for the hook nail deformily is reported with good results.

Klippel-Trenaunay syndrome (KTS) is a rare congenital disorder and is essentially a disorder of capillary, venous, and lymphatic malformations. Hematochezia is the most common symptom associated with intestinal hemangiomatosis and remains one of the life-threatening emergencies in KTS. We reported one patient of KTS presented with rectal bleeding and severe anemia who was successfully managed by sphincter-saving operation.

The endometrial osseous metaplasia is one of a very rare conditions which gynecologists experience clinically. The characteristics of this disease are history of irregular menstruation, recurrent abortion, infertility with histopathologic evidence of chronic inflammation, and bone formation. This is one of heterotopia(the presence of mature tissue in abnormal location) histopathologically and it is important clinically that infertility can be brought about in the reproductive age women, but the etiology and treatment about this disease are unclear. A case of endometrial osseous metaplasia diagnosed by endometrial biopsy is presented with a brief review of the literatures.

PURPOSE: Preoperative assessment of the depth of invasion in the rectal wall and of lymph node metastases is very important in determining the treatment modality in rectal cancer. The purposes of study were to evaluate the accuracy of transrectal ultrasonography (TRUS) in preoperative staging of rectal cancer and to compare that accuracy with the accuracy for computed tomography (CT). METHODS: We reviewed 59 patients who were diagnosed as having rectal cancer and who had been staged by using TRUS and CT preoperatively. Ultrasonographic tumor (uT) and nodal (uN) stage and computerized tomographic tumor (cT) and nodal (cN) stage were entered into the database prospectively. The accuracy of each staging was compared with the pathologic staging. The accuracy, the sensitivity, the specificity, the positive predictive value, and the negative predictive value of each diagnostic test were calculated. Chi- square tests were conducted to identify the factors influencing the accuracy. RESULTS: The accuracies of TRUS and CT in assessing the depth of invasion were 66.1% and 62.5%, respectively. The accuracies of TRUS and CT in assessing the nodal involvement in patients treated with radical surgery were 70.4% and 63.6%, respectively. For detection of fat infiltration, the sensitivities were 97.4% for TRUS and 76.3% for CT. The specificities were 45.0% for TRUS and 55.6% for CT. The sensitivities for detection of lymph node involvement were 59.3% for TRUS and 42.9% for CT. The specificities were 81.5% for TRUS and 85.2% for CT. The gross appearance of the tumor had a significant influence on the assessment of the depth of invasion (P=0.015). In 9 out of 77 patients (11.7%) could not be performed the TRUS examination due to obstruction or the location of the tumor. CONCLUSIONS: In spite of some limitations, TRUS is considered a very useful tool in the preoperative assessment of the depth of invasion and of the lymph node involvement in rectal cancer. However, CT examination is mandatory to overcome the limitations of TRUS in the preoperative diagnosis of rectal cancers.

Hepatic tuberculosis is usually associated with active pulmonary or miliary tuberculosis. The occurrence of an isolated hepatic mass-forming tuberculosis with no evidence of tuberculosis elsewhere is rare. We report a case of a 31-year-old male with a solitary hepatic granuloma mimicking a mass-forming intrahepatic cholangiocarcinoma. Ultrasonography, computed tomography, magnetic resonance imaging, and positron emission tomography of the abdomen showed a malignant tumor-like lesion. We then conducted endoscopic ultrasonography (EUS) and EUS-guided fine-needle aspiration (EUS-FNA) for confirmation of the hepatic hilar mass, which was found to be a hepatic tuberculosis granuloma as the final diagnosis.

PURPOSE: With recent anorectal physiologic studies, functional etiologies of pelvic outlet obstructive disease were evaluated in detail. The current study was designed to assess the clinical and the physiologic characteristics of patients with pelvic outlet obstructive disease. METHODS: one hundred two (102) patients with pelvic outlet obstructive disease were evaluated with anorectal physiologic studies, including the colonic transit time (n=66), anorectal manometry (n=88), defecography (n=102), anal sphincter EMG (n=50), and colonoscopy or barium enema (n=77). The patients were categorized as group I (nonrelaxing puborectalis syndrome), group II (rectocele), group III (sigmoidocele), and group IV (rectoanal intussusception). The clinical and the physiologic characteristics were compared between the groups. RESULTS: The mean age was 51.9 years, and the sex ratio was 1:1.9. the populations of the groups were group I 45.1% (n=46), group II 36.3% (n=37), group III 5.9% (n=6), and group IV 9.8% (n=10). In group II and group III, co-existing etiologies were more, and the incidences of female patients was higher (P<0.05). Delayed colonic transit time was noted in 11 patients (17%). Diverticula was observed in 6 patients (8%), polyps in 12 patients (16%), and melanosis coli in 14 patients (18%). On anorectal manometry, group I showed higher maximal voluntary contraction and mean squeezing pressure than the other groups (P<0.05). On defecography, group I had a shorter perineal descent at rest and a smaller anorectal angle at push (P<0.05). CONCLUSIONS: The current study showed the clinical and the physiologic characteristics of the each functional etiology in patients with pelvic outlet obstructive disease. These results provide fundamental data for diagnosis of and tailored therapy for pelvic outlet obstructive disease.

BACKGROUND/AIMS: Patients with cholangiocarcinoma usually present at an advanced stage, and more than 50% of cases are not resectable at the time of diagnosis. Recently, photodynamic therapy (PDT) has been proposed as a palliative and neoadjuvant modality. We evaluated whether combination of PDT and chemotherapy is more effective than PDT alone. METHODS: In total, 161 patients with cholangiocarcinoma diagnosed between February 1999 and September 2009 were evaluated. Sixteen patients were treated with PDT and chemotherapy (group A), and 58 were treated with PDT (group B). RESULTS: The median survival was 538 days (95% confidence interval [CI], 475.3 to 600.7) in group A and 334 days (95% CI, 252.5 to 415.5) in group B (p=0.05). Lymph node metastasis status, serum bilirubin of pretreatment, tumor node metastasis stage, treatment method (PDT with chemotherapy vs PDT alone), time to PDT and the number of PDT sessions were prognostic factors with statistical significance in the univariate analysis. A multivariate analysis showed that PDT with chemotherapy and more than two sessions of PDT were significant independent predictors of longer survival in advanced cholangiocarcinoma (hazard ratio [HR], 2.23; 95% CI, 1.18 to 4.20; p=0.013 vs HR, 1.79; 95% CI, 1.044 to 3.083; p=0.034). CONCLUSIONS: PDT with chemotherapy results in longer survival than PDT alone.

PURPOSE: Biofeedback treatment is thought to be appropriate for patients with nonrelaxing puborectalis syndrome (NRPR). The aim of this study is to analyze the physiologic characteristics and to assess the outcomes of biofeedback treatment for patients with NRPR. METHODS: Forty-six (46) patients with NRPR were evaluated with anorectal physiologic studies, including colonic transit time (n=26), anorectal manometry (n=41), defecography (n=46), anal sphincter EMG (n=28), and colonoscopy or barium enema (n=33). The treatment consisted of a training program with EMG-based biofeedback for 30 minutes once a week and routine supportive care, including Kegel practice. RESULTS: The mean age was 52.8 years, and the sex ratio was 1 male to 0.6 female. A delayed colonic transit time was noted in 5 patients (19.26%). In the NRPR group, the maximal voluntary contraction and the mean squeezing pressure were higher than they were for other patients with pelvic outlet obstructive disease. Also, the perineal descents and the dynamic change of anorectal angle were shorter. Polyps were observed in 6 patients (18.2%), melanosis coli in 4 patients (12.1%), and diverticula in 3 patients (9.1%). The rectoanal inhibitory reflex (RAIR) was negative in 3 patients (7.3%). The patients underwent a mean of 4.0 sessions, and the mean follow-up was 7.4 months. Twenty-three (23) patients (82.1%) experienced improved of symptoms or EMG findings. The patients (17.9%) who did not improve had several abnormal findings: neuro-psychologic disease with delayed colonic transit time in 2 cases, negative RAIR in 2 cases, and melanosis coli in one case. CONCLUSIONS: We think that biofeedback training is an effective treatment for patients with NRPR. In addition, several factors, such as neuro-psychologic diseases, delayed colonic transit time, negative RAIR, or melanosis coli may influence the prognosis for biofeedback treatment, so further large-scaled studies will be needed to confirm these findings.
