BACKGROUND/AIMS: A villous tumor, histologically villous or tubulovillous adenoma, is a clinical challenge because of its higher potential for malignancy and higher recurrence rate. However, information and experience with these tumors in the Korean people is still lacking. For that reason, we designed this study to review and analyze the colonoscopic features, the potential for malignancy, and the treatiment with respect to the confirmation of guidelines for the accurate diagnosis and reasonable management of such tumors in the Korean population. MATERIALS AND METHODS: We performed 753 polypectomies, including 4 transanal excisions and several bowel resections, from January 1996 to May 1997 at Song-Do Colorectal Hospital in Seoul, Among them, 447 cases (59.4%) were adenomas, comprising 405 (53.8%) tubular adenomas, 31 (4.1%) tubulovillous adenomas, and 11 (1.5%) villous adenomas. We analyzed the 42 (5.6%) tubulovillous and villous adenomas.

Since laparoscopic cholecystectomy(LC) was first introduced in early 1990 in Korea, LC is now widely used with an acknowledgement of the benefits of LC.The author retrospectively analyzed 120 patients who were treated by LC and 40 patients who were treated by open cholecystectomy(OC), at the Department of Surgery, Kwang Hye Hospital from Jan. 1992 to July 1995. For the statistical analysis of the variables, student's t-test and ANOVA F-test were used to assess the differences between two groups(p value = 0.05). The obtained results were as follows. 1. The mean age and sex ratio(M:F) between LC and OC group were 48.3-years-old and 1:1.45, 57.6-years-old and 1:3.4, respectively. 2. Associated diseases were observed in 62 patients (51.7%) of the LC group and 23 patients (57.5%) of the OC group. Peptic ulcer and DM were most frequent, respectively. 3. 20 patients (16.7%) had a previous abdominal operation, with appendectomy, the most frequent among them. 4. The operation times(p=0.05), hospitalization stay(p=0.0001), and postoperative hospitalization stay(p=0.0001) were significantly shorter in the LC group than in the OC group. 5. In the preoperative, intraoperative, and postoperative ABGA of the LC group, especially, intraoperative PCO2 was increased due to CO2 retension and metabolic acidosis was developed, intraoperatively. PaO2 was excessively increased due to hyperventilation to correct the metabolic acidosis, intraoperatively. Satistically, intraoperative pH (p=0.0001), PaO2 (p=0.0001), PCO2 (p=0.0001) except bicarbonate (p=0.1987) were significantly changed, compared with preoperative pH or postoperative pH. 6. Operative cholangiography(OPC) was proceeded in 17 patients(14.2%) and concurrent laparoscopic appendectomy was done in 7 patients (5.8%) of the LC group. 7. Postoperative complications were occurred in 19 patients (15.8%) of the LC group. 3 patients (2.5%) were explorated, the remainders were recovered by conservative treatment. 8. On pathologic findings, cholelithiasis and chronic cholecystitis with 105 patients (87.5%) were most frequent in the LC group. In the OC group, cholelithiasis and chronic cholelithiasis with 25 patients (62.5%) were also most frequent, GB empyema with 8 patients (20%), acute cholecystitis with 7 patients (17.5%). Conclusively, laparoscopic cholecystectomy can be safely applied with lower morbidity, shorter operation times, and shorter hospital stay in selected patients.

The pain after a hemorrhoidectomy is widely feared by many patients who are mostly still treated with oral/intramuscular narcotics to control their pain postoperatively. In an effort to decrease posthemorrhoidectomy pain by applying newer methods of analgesia, a prospective trial was conducted to investigate the postoperative analgesic effect of Tarasyn(R) (ketorolac tromethamine) injected into the internal sphincter muscle at the time of the hemorrhoidectomy. Tarasyn(R) is a nonsteroidal anti-inflammatory drug introduced for intramuscular injection to control postoperative pain. It's action is peripheral. Therefore, it seems appropriate to inject it directly into the anal sphincter muscles when these are exposed during anorectal procedures. A total loading dose of 60 mg(2 cc, 30 mg/ml) of ketorolac was used intraoperatively. It was injected intramuscularly locally after completion of hemorrhoidectomy. Postoperative pain after a hemorrhoidectomy can be safely controlled in a patient by using newer methods of pain control, including supplemental use of the nonsteroidal analgesic ketorolac, which allows early release of the patient, the day of surgery by diminishing the postoperative pain in our study group. Another important advantage of a local injection of ketorolac was the elimination of urinary retention.

Ulcerative colitis is increasing now in Korea, and the diagnosis has become relatively easy because sigmoidoscopy and colonoscopy are frequently used. However, the result of treatment is not satisfactory because the relapse rate is very high. Hence, the aim of treatment is to put this disease into remission as soon as possible and to keep it in remission. The authors reviewed 80 confirmed ulcerative colitis cases which were treated from Feb. 1997 to Sep. 1997 at Song Do Colorectal Hospital. The results are as follows: 1) The male to female ratio for these 80 cases was 41:39, and the most prevalent age group was the 4th decade. 2) The most common clinical symptoms were anal bleeding in 77 cases(96%), diarrhea in 68 cases(85%), and abdominal pain in 21 cases(26%). 3) The extension of the disease were the proctitis in 47 cases(59%), the left - side colitis in 28 cases(35%), the total colitis in 4 cases(5%), and the atypical colitis in 1 case(1.3%). 4) The duration of the disease was below 6 month in 30 cases, 6 months to 1 year in 35 cases, and 1~5 years in 11 cases, and over 5 years in 4 cases. 5) Clinical types were the one-attack-only type(18 cases), the relapsing-remitting type(60 cases), the chronic continuous type(1 case), and the acute fulminating type(1 case). 6) In the 28 cases of left side colitis, the average time to remission depended on the medication was 18 days for a 5-ASA 5-ASA suppository, 14.5 days for a 5-ASA oral steroid, and 8.3 days for a 5-ASA budesonide enema. Thus, a budesonide enema is the most effective medication for obtaining remission. 7) The most commonly suspected predisposing factors for relapse were cessation of medication(58 cases), mental stress(18 cases), physical stress(15 cases), and inadequate diet(8 cases). As indicated above, ulcerative colitis is increasing now in Korea, and the rectum is the most commonly involved site for this disease. Relapsing-remitting ulcerative colitis is the most frequently occurring type. Almost all cases were easily put into remission within 4 weeks, but relapse frequently occurred. Suspected predisposing factors, such as mental stress, physical stress, and inadequate diet, should be avoided in order to prevent relapse, and medication, such as 5-aminosalicylic acid, should be continued to maintain remission.

BACKGROUND: Many liver transplant surgeons think that portal vein cold perfusion is essential during liver procurement. However, it may limit the perfusion to the pancreas and small intestine and may lengthen the procedure. If visceral arteries are not ligated, perfusates passing the spleen and the small intestine can eventually cool the liver. Aorta only perfusion is rapid and easy and can be performed with the better perfusion of the pancreas and small intestine than with conventional perfusion. However, it may delay the cooling of the liver. The purpose of this study was to evaluate the feasibility of aorta only perfusion compared with conventional perfusion as an alternative method for multiorgan procurement. METHODS: Male mongrel dogs of 16-18 kg were used. In the control group (n=5), standard multiorgan procurement method, including portal vein perfusion, was performed. In experimental group (n=4), aorta only perfusion without superior mesenteric artery ligation was performed. An isotonic citrate solution was used as a perfusate. In the control group, a total amount of 800 to 1000 ml of the perfusate was used to each portal vein and aorta perfusion. In the experimental group, 1500 to 2000 ml of the perfusate were infused only to aorta. After donor liver procurement, 200 to 300 ml of the perfusate was added to the portal vein and the hepatic artery at a ratio of 8:2. Core temperature changes of the liver during perfusion with preservation solution were checked at 5-second intervals. Standard orthotopic liver transplantation was performed. Wedge liver biopsies were performed after procurement and 1 hour after reperfusion. A liver function test was performed, and the hematologic features, and the coagulation profiles were measured preoperatively and one hour after reperfusion. In histologic examination, injuries of hepatic vessel endothelia and hepatocytes were evaluated semiquantitatively under light microscopic and electron microscopic exams. RESULTS: A comparion of the two groups showed no differences in operation time, anhepatic time, and ischemic time. The values of the leukocyte count, the hemoglobin, hematocrit, the prothrombin time,the partial thromboplastin time, the total protein/albumin, bilirubin, ALT/AST and alkaline phosphatase were not different between two groups. Falling of liver core temperature during perfusion was slightly delayed in experimental group. However the delayed time was less than 2 minutes until to reach the temperature of 10oC. The histological grading scores of hepatocytes and endothelial damage determined from light microscopic and electron microscopic examinations were not different from each other. CONCLUSIONS: There was no difference between aorta only perfusion group and portal vein perfusion group, including the severity of liver damages. Therefore, liver procurement without in situ portal perfusion may be a reasonable alternative to combined portal and aorta perfusion on the background of rapid procurement and benefit to the pancreas and small intestine procurement.
