Hemorrhoid and anal fissure are common diseases in Korea. It has been demonstrated that patients with hemorrhoidal disease have increased activity of the internal anal sphincter. The fissure causes increased contraction in the internal anal sphincter, thereby increasing pressure in the anal canal. Many studies have reported differences in the anal canal pressures between males and females. Moreover, some papers have shown that sphincter pressures decrease with age. But the majority of these studies were not specific for the hemorrhoid and anal fissure. Therefore, we studied the effect of age and gender on anal pressure in hemorrhoid and anal fissure. Two hundred ninety six patients with hemorrhoid and sixty eight patients with anal fissure were retrospectively assessed. Anorectal manometry using a radial eight-port catheter was performed during resting and squeezing maneuvers of the anal sphincter. In hemorrhoid reduction in maximal average resting(MARP) and squeezing pressure(MASP) were found from the sixth decade, however in anal fissure reduction in MARP and MASP were found in the third decade. In hemorrhoid significant decrease of MARP and MASP were noted in entire ages of female, however in anal fissure increase of MARP and MASP were noted in fifth and sixth decade of female. In conclusion, in hemorrhoid both resting and squeezing pressure decrease with age in female. In anal fissure both resting and squeezing pressure decrease in third decade and in male with fifth and sixth decade.

Natural cytotoxicity mediated by natural killer (NK) cells is believed to play an important role in host anticancer defense mechanisms. The aim of this study is to compare the number of NK cells in patients with colorectal cancer and hemorrhoids, and before and after surgery in patients with colorectal cancer. Twenty colorectal cancer patients and twenty hemorrhoid ones were studied. Venous blood samples were obtained preoperatively, and on the 7th, and 14th postoperative days. Mononuclear cells were isolated over Ficoll-Hypaque gradients, and T cells, B cells, and NK cells were measured with CD3 FITC (T cell), CD 19 PE (B cell), and CD56 FITC (NK cell) antibody, The number of T cell (/mm3) was 1224, 1280, and 1125 at preoperative, 7th, and 14th postoperative day in hemorrhoid patients and 1195, 901, and 1060 in colorectal cancer patients respectively. The number of B cell (/mm3) was 243, 160, and 250 in hemorrhoid patients and 147, 78, and 113 in colorectal cancer patients. The number NK cell (/mm3) was 148, 156, and 143 in hemorrhoid patients and 129, 85, and 128 in colorectal cancer patients. There was no difference among Dukes stages in the number of NK cells. In conclusion, the number of NK cells was not changed in colorectal cancer patients compared with hemorrhoid ones. Major operation changed the number of NK cells in colorectal cancer patients.

The Di(a+b-) phenotype is extremely rare among Caucaclans and mostly confined to mongoloids. The incidences of Di antigen among Koreans were reported to be 6.1 to 14.5%, with an average of 9.6%; it can be calculated that the frequency of Di(a+b-) is 0.25% on the average. Authors report the first case of hemolytic disease of the newborn due to anti-Dib in Korea. The Diego phenotypes of the mother, baby and father were Di(a+b-), Di(a+b+) and Di (a-b+), respectively. The mother's serum and eluate from infant's erythrocytes contained anti-DP antibody active in the antiglobulin phase. After transfusions of Di-negative red cells from the mother and mother's relative, the patient was recovered from anemia and jaundice.

Colon has the highest bacterial concentration in the gastrointestinal tract. When the colon is perforated, the operator has to decide whether to perform primary closure, resection with anastomosis, proximal colostomy, and exteriorizatoion. In this retrospective study, from October, 1993, through July 1998, 56 patient with panperitonitis due to colon perforation were operated at Ewha womans University medical center. The rectal perforation was limited the intraperitoneal portion. Our cases were divided into two groups. Group I included 34 patients who treated with one step operations of primaryrepair or resection anastomosis. Group II included 22 patients who treated with two step operations of proximal colostomy or exteriorization. The one step operations were performed in 34 patients, proximal colostomy in 21 patients, and exteriorization in 1 patient. There was 13.7% in the incidence of motality and 33.3% in the incidence of morbidity. The Chi-square test was used to evaluate the significance of differences between two groups. Independent risk factors for adverse outcomes were compared and used to analyse the probability for adverse outcomes with respect to the mode of treatmen. The mode of treatment was not dependent on the risk factors. These results suggest that one could select positively primary closure or resection with anastomosis for the treatment of patients with panperitonitis due to colon perforation.

Synchronous neoplams are uncommon condition but the incidence is now being increased. The situation is rare when these tumors comes from different origin. We experienced the case with synchronous sigmoid colon cancer and anal squamous cell carcinoma with rectal mucosal metastasis. The patient was 61 years old male. He complained of intermittent hematochezia since 3~4 months ago. The patient underwent anterior resection for colon cancer and wide excision for anal squamous cell carcinoma. After surgical operation, postoperative adjuvant chemotherapy (5-FU + Leucovorin) and radiotherapy were done. In this case, we could preserve the anal sphincter using combined therapy. We think that this type of management may be useful treatment in patients with colon cancer and anal squamous cell cancer simultaneously.

Although the carotid endarterectomy presently represents the standard therapeutic approach for most patients with significant carotid artery stenosis, a percutaneous transluminal angioplasty (PTA) with stenting has become an alternative method for treating patients with co-mobid conditions, particulary coronary artery disease. A PTA with stenting has the potential for being safer, less traumatic, more cost-effective, and useful in patients at high surgical risk. As well, they are not limited to the cervical carotid artery. But it is reported that carotid angioplasty by femoral approach is difficult to do in 1 - 2% of patients with carotid stenosis due to abnormal origin of carotid artery or occlusion of femoral arteries. We succeeded in PTA with stenting of tight stenosis of right internal carotid artery through the transseptal approach in case of a sharply angled right brachiocephalic artery take-off from the aorta. The transseptal approach can be used for PTA with stenting in case of problems with femoral approach.
