BACKGROUND/AIM: Serial measurement of serum carcinoembryonic antigen was assessed to define its significance and to determine the adequacy in detecting recurrence after curative resection for colorectal cancer. METHODS: Six hundred forty-five patients with colorectal cancer underwent curative resection were included. The median follow-up period was 49 months (range, 24~94 months). Serum CEA was analyzed in accordance with location, histologic differentiation, stage of the tumor, recurrence and survival. RESULTS: The incidence of elevated preoperative serum CEA (> 6 ng/ml) was correlated with tumor stage (stage I vs. II, P=0.01; stage II vs. III, P=0.0001). Fifty five patients among 87 patients with recurrence (63.2%) had concomitant elevation of serum CEA, whereas 32 of 558 patients (5.7%) without recurrence showed a false-positive result. Measurement of serum CEA was more sensitive in patients with elevated preoperative serum CEA and liver metastases than in patients without elevated preoperative serum CEA and local recurrence (P=0.0397). The leading time of serum CEA between the first elevated serum CEA and the identification of recurrence was 3.5 months (range, 1~12 month). Tumor stage and preoperative serum CEA level were found to be significant prognostic variables by multivariate analysis. The overall 5-year survival rate in the normal preoperative serum CEA and the elevated group were 76% and 64% respectively (P=0.00019). CONCLUSION: Serum CEA seemed to be closely correlated with survival and to be an useful tool to detect recurrence after curative resection for colorectal cancer. The appropriate measurement of serum CEA might be suggested in stage II and III postoperatively: every three month for two years, every 6 month for succeeding 2 years, and annually thereafter. Monitoring of serum CEA in stage I could be individualized by preoperative serum CEA and clinical course.

Enlow's counterpart analysis explains the complex with anatomic and developmental characteristics where craniofacial aspect of individuals has been developed. The analysis does not compare individual measurement with the normal value from the average of majority but analyzes by comparison of values that each individual has. This study was to clarify the Korean craniofacial skeletal pattern using Enlow's counterpart analysis considering the fact that the craniofacial skeletal pattern has racial and regional variations. This research will be helpful in the future for growth research and research of the orthognathic For this study, the samples were consisted of 100 Korean adult subjects(50 males and 50 females) who had normal occlusion and pleasing face. Measurement points and lines were established using Enlow's counterpart analysis and they were statistically evaluated. The results indicated that: 1. The average angle between PCF and PMV was 38.54 degrees in males and 38.43 degrees in females, and the average Wits' appraisal was -2.51 in males and -2.3 in females. The ramus alignment(R4) was 1.89 in males and 2.36 in females. 2. It shows that females have a longer ramus than the PCF compared to the males, because there was a significant difference in Ramus/PCF horizontal dimensions (Skeletal A3-B3) between female and male subjects 3. It shows that males have a longer mandibular corpus than the maxilla compared to the females, because there was a significant difference in Maxillary/Mandibular arches(Skeletal A4-B4) between male and female subjects 4. In cranial floor+maxilla/ramus+corpus at A and B points(A1-B1), which represents difference in total horizontal length between the maxilla and mandible, there was no significant difference between males and females. In conclusions, compared to Caucasian, Korean have more depressed midface, prognathic mandible, and ramus that rotates inferioposterior. Also, we observe that Korean women have larger ramus posterior cranial base, as compared with Korean men. Consequently, the total length of maxilla and mandible does not show any difference, because man's mandible is longer than maxilla in comparison with woman's one.

The occurrence of the colonic obstruction secondary to colorectal carcinoma (CRC) has been reported in 7~30% of the CRC patients. It is generally believed that obstructive CRC is associated with a poor prognosis with respect to operative mortality and five-year survival. A series of 1064 cases of the CRC treated surgically at Asan Medical Center from June 1989 to December 1996 has been analyzed to compare clinicopathological findings between obstructive and non-obstructive CRC and to evaluate surgical treatment options in obstructive CRC. Complete obstruction was present in 49 cases (4.6%). There were no differences between obstructive and non-obstructive CRC in tumor location, size, Dukes' stage, and differentiation. In forty-nine obstructive CRC cases, primary resections were performed in 29 cases after peri-operative bowel decompression. In this group, right colon cancer was more prevalent than staged operation group (45% vs. 5%, P<0.05) and hospital stay was significantly short (16 days vs. 38 days, P<0.05). Postoperative complication rate was higher in staged operation group (65% vs. 28%, P=0.01). It may be due to stoma related wound complication. In obstructive left colon cancer, there was a significant difference in complication rate between primary resection and staged operation (P<0.05). Overall 5-year survival rate were 66% and 53% in non-obstructive and obstructive group, respectively. Survival rate according to the Dukes' B and C stages did not show statistical differences, either. Conclusively, primary resection is preferred to the obstructive CRC when supportive care, preoperative bowel decompression, and intraoperative colonic irrigation were performed adequately.

PURPOSE: In this retrospective study, we aimed to compare the clinical characteristics of inguinal hernia developed after radical retropubic surgery for prostate cancer to the hernia without previous radical prostatectomy. METHODS: Twenty-three patients (group A) who had radical retropubic surgery for prostate cancer underwent laparoscopic or open tension-free inguinal hernia repair from March 2007 to February 2011. Nine hundred and forty patients (group B) without previous radical retropubic surgery received laparoscopic or tension-free open hernia operation. RESULTS: Group A was older than group B (mean +/- standard deviation, 69.6 +/- 7.2 vs. 54.1 +/- 16.1; P < 0.001). Right side (73.9%) and indirect type (91.3%) in group A were more prevalent than in group B (51.5% and 69.4%, respectively) with statistic significance (P = 0.020 and P = 0.023). The rate of laparoscopic surgery in group B (n = 862, 91.7%) was higher than in group A (n = 14, 64.3%, P < 0.001). In comparing perioperative variables between the two groups, operative time (49.4 +/- 23.5 minutes) and hospital stay (1.9 +/- 0.7 days) in group A were longer than in group B (38.9 +/- 16.9, 1.1 +/- 0.2; P = 0.046 and P < 0.001, respectively) and pain score at 7 days in group A was higher than in group B (3.1 +/- 0.7 vs. 2.3 +/- 1.0, P < 0.001). Postoperative recurrence rate was not significantly different between the two groups. CONCLUSION: Inguinal hernia following radical retropubic surgery for prostate cancer was predominantly right side and indirect type with statistic significance compared to hernias without previous radical prostatectomy.

Backgroud: In one-lung ventilation using the left-sided double-lumen tube (LDLT), it is important to place the LDLT in correct position to maintain adequate ventilation. We investigated the frequency of and the factors affecting the LDLT malposition in endotracheal intubation. Methods: Ninety one (55 male and 36 female) patients were observed. After endotracheal intubation, using 35 and 37 Fr. sized Robertshaw type LDLT, auscultation and fiberoptic bronchoscope were performed to make sure the correct position of LDLT. The heights, weights, age, and sex were noted. The lengths and diameters of trachea, and the angles and diameters of both bronchi on chest x-ray were measured for comparison. Results: Normal in auscultation and gross malposition were 87.9% and 12.1%. Among those normal in auscultation, normal in bronchoscope, advancing and removing fine malposition were 66.2%, 18.8% and 15.0%, respectively. The angle of left bronchus is 37.71+/-4.60degrees in normal in ausculation and 37.71+/-4.60degrees in gross malposition. The length of trachea is 13.41+/-0.90 cm in normal in bronchoscope, 14.49+/-0.78 cm in advancing fine malposition and 11.86+/-0.35 cm in removing fine malposition. The patient's height is 167.27+/-7.12 cm in normal in brochoscope, 172.45+/-6.67 cm in advancing fine malposition and 163.12+/-6.54 cm in removing fine malposition. Conclusions: The angle of left bronchus is a factor affecting gross malposition. And the length of trachea and the patient's height are factors affecting fine malposition. Thus it is necessary to obtain in advance information on patient's height, length of trachea and angle of left bronchus on chest x-ray, to reduce the occurrence of the LDLT malposition.

The authors have experienced 9 cases of postgastrectomy efferent loop obstruction during the past 16 months' period and analyzed the clinical features, radiological findings, causes, and types of obstruction. The incidence of efferent loop obstruction was 1.3%(9/673). Among the 9 cases, eight patients were male and one patient was female. Median age was 60 years and more than half(5 out of 9 cases) of the patients were obese(defined by more than 110% of ideal body weight). None of the cases showed signs of strangulation, including persistent pain, fever, focal abdominal tenderness, and/or leukocytosis. Gastrointestinal anastomoses were done using a GIA stapler in 6 cases, and manually in 3 cases. The diagnoses were made on the basis of clinical symptoms and signs, further supported by radiologic contrast studies. All the patients were initially treated with conservative measures, including nasogastric drainage and fluid therapy for about 2 weeks in average. 7 cases underwent re-laparotomy using separate left subcostal incisions as conservative management had failed. Among the relaparotomy cases, adhesiolysis and side to side jejunojejunostomy were performed in 5 patients, Roux-en-Y gastrojejunostomy in 1 patient, and gastrojejunostomy revision in 1 patient. Causes of the obstruction in the seven re-opened cases were confirmed as postoperative adhesion. The authors have analyzed the pattern of obstruction and classified the patterns into 4 types. One of the remaining two patients underwent balloon dilatation successfully and the other was managed with prolonged nasogastric decompression. The average hospital stay was 32 days. Adequate omentectomy, gentle tissue handling during dissection, avoidance of ischemia along the suture line of anastomosis, and the use of biologically inert suture material would prevent this kind of postoperative adhesive obstruction.
