PURPOSE: RUNX3, a novel tumor suppressor, is frequently inactivated in gastric cancer. In the present study, we examined the pattern of RUNX3 expression in gastric cancer cells from gastric cancer specimens and the impact of its alteration on clinical outcome. MATERIALS AND METHODS: A total of 124 samples of both gastric cancer and normal tissue were obtained from 124 patients who underwent curative gastrectomy at the Seoul Medical Center from January 2001 to December 2005. RUNX3 expression was determined by immunohistochemical staining, and the results were analyzed. Statistical analysis wabased on clinicopathological findings and differences in survival rates. RESULTS: The mean age of the patients was 61 years, and the male:female ratio was 1.9:1. The expression rate of RUNX3 was 59.7% (74/124). The expression rate was higher in differentiated gastric cancers (nucleus: 9.1%, cytoplasm: 57.6%) than in the undifferentiated types (nucleus: 5.2%, cytoplasm: 46.6%) (P=0.133). The 5-year survival rates according to RUNX3 expression determined from cancer tissue were 88.9% for the nucleus +/- cytoplasm(+) group of patients, 76.1% for the cytoplasm only (+) group of patients, and 65.3% for the RUNX3 negative expression group of patients (P=0.626). Only UICC TNM staging showed statistical significance related to the survival rate, as determined by multivariate analysis. CONCLUSION: The RUNX3 expression rate was higher in differentiated gastric cancer than in the undifferentiated types without significance. Although RUNX3 expression predicted better survival, based on multivariate analysis, the finding was not statistically significant. More cases should be further evaluated.

BACKGROUND/AIMS: Hepatoduodenal ligament lymph node (LN) dissection has been performed as a part of extended LN dissection during the operation for gastric cancer. And additional cholecystectomy has been performed for more radical node dissection and prevention of cholelithiasis in some centers. There are rare studies and reports about the injury of bile duct system with the operation for gastric cancer. The aim of this study is to evaluate the risk of biliary tree injury with LN dissection for gastric cancer. METHODS: 254 patients of gastric cancer were treated with gastrectomy with LN dissection at Kangnam general hospital between January 1996 and December 2001. Among this group, 151 patients of advanced gastric cancer underwent extended LN dissection of D2+alpha or D3 including hepatoduodenal ligament LN and 69 patients of early gastric cancer underwent D2. And we routinely conducted cholecystectomy for advanced and early gastric cancer. Of these patients, 5 cases without remained or recurred tumor of bile leakage after operation were reviewed. And we analyzed the changes of liver function tests (LFT) of 15 patients of early gastric cancer and 21 patients of advanced gastric cancer whose LFT follow-up data were available. RESULTS: The rate of bile leakage was 2.3% (5 patients) after LN dissection of hepatoduodenal ligament for gastric cancer. Among this group, 3 patients underwent reoperation due to unexpected bile leakage and 2 patients underwent T tube choledochostomy due to minor injury to common hepatic duct on operation. One patient died of sepsis with continued bile leakage after T tube removal on the postoperative 41st day. The serum alkaline phosphatase was increased after operation especially in advanced gastric cancer without clinical significance and there was no other significant abnormality in LFT after hepatoduodenal LN dissection and cholecystectomy in non-recurrent cases. CONCLUSION: Extended lymph node dissection including hepatoduodenal ligament LN and cholecystectomy may have the possibility of increasing the risk of bile duct injury. It is important to select the patients who will benefit from hepatoduodenal ligament LN dissection and cholecystectomy. And meticulous surgical technique to operate biliary tract and adequate management of biliary injury are needed.

PURPOSE: There have been many different kinds of operations for obstructing left colon (distal to splenic flexure) cancer and rectal cancer because immediate resection and anastomosis was known to cause many complications. We performed this study to analyse operative cases and evaluate which procedure had the better result. METHODS: Thirty-six cases of left colon cancer and rectal cancer with complete obstruction were analysed from April 1990 to January 2001 and those cases were divided into two groups, the group of staged procedure and the group of primary resection. 28 cases were curative operations and 8 cases were palliative operations. RESULTS: The group of staged procedures had 17 cases of curative operations with 1st. stage-colostomy and 2nd. stage-cancer resection. And the group of primary resection had 11 cases of curative operations, 6 cases of Hartmann's procedures, 2 cases with intraoperative colonic lavage and resection and 3 cases with cancer resection, anastomosis and proximal colostomy. There were no differences in the distribution of age and cancer stage between two groups. In both groups, the sigmoid colon was the most prevalent obstruction site. The staged procedure group had higher operative mortality (25%) than the primary resection group (8%). And 5-year survival rate of the primary resection group was higher than that of the staged procedure group (45%: 33%), but there was no statistical significance. CONCLUSIONS: We think that the primary resection is the better surgical procedure because of shorter hospital stay and fewer operations in the treatment of obstructing left colon and rectal cancer.

Retroperitoneal fibrosis is a rare disease characterized by the formation of dense plaque of fibrous tissue covering the retroperitoneal structures. This disease is commonly presented as ureteral obstruction, but the involvement of duodenum is rare. We report a case of retroperitoneal fibrosis which was complicated with duodenal stenosis and was successfully treated with corticosteroids. A 58-yr-old man, who had history of aorto-iliac bypass graft due to arteriosclerosis obliterans with infrarenal aortic occlusion was admitted to the hospital with abdominal pain and a mass. Abdominal CT scan revealed the periaortic soft tissue mass encircling grafted aorta and stenosis of duodenal third portion. Retroperitoneal fibrosis with duodenal stenosis was diagnosed and prednisolone therapy was initiated. Follow-up CT scan showed that the patient responded to prednisolone therapy with eased pain, shrinking periaortic mass, and reduced duodenal stenosis.

OBJECTIVE: To evaluate the effect of progesterone supplementation during the luteal phase on pregnancy outcome in natural frozen-thawed embyo transfer (FTET) cycles. METHODS: In this retrospective cohort study, 228 consecutive patients who underwent FTET cycles between January 2009 and September 2012 were included. One hundred forty-five patients received luteal progesterone support (P group) but 83 patients did not receive any progesterone supplementation during luteal phase (control group). RESULTS: There were no differences in patients' characteristics between the two groups. The two groups were similar with respect to the characteristics of previous fresh in vitro fertilization cycle in which embryos were cryopreserved including the numbers of oocytes retrieved, mature oocytes, fertilized oocytes, grade 1 or 2 embryos and frozen embryos. Also, significant differences were not observed between the P and control groups in clinical pregnancy rate, embryo implantation rate and multiple pregnancy rate. However, miscarriage rate was significantly lower in the P group and live birth rate was significantly higher in the P group than in the control group (P<0.05, P<0.05). CONCLUSION: Our results suggest that luteal phase progesterone supplementation decreases miscarriage rate and improves live birth rate in natural FTET cycles.

PURPOSE: We performed this study to assess the suitability of conventional angiography (CA) vs. multi-detector row helical CT angiogram (MD-CTA) as a method of preoperative diagnostic imaging for low extremity arterial surgery. METHODS: From February 2004 to September 2006, 23 patients (4 claudicants, 19 limb-threatening ischemia) were studied with CA and MD-CTA preoperatively. The site and degree of stenotic or occlusive lesions in arterial segments from the renal artery to the dorsalis pedis artery were compared with both methods. We also compared the surgical inflow and outflow site changes in preoperative planning based on CA and MD-CTA and the final outcome. Additional diagnostic value and test-related complications were also analyzed. RESULTS: The median age of patients was 68 years old (range: 43~89 years), with a male to female ratio of 1.3:1. Twenty-three patients had CA after an MD-CTA scan. One hundred fifty lesions were detected in these patients. The total ratio of consistency for occlusion in CA vs. MD-CTA was 69.6%. Three patients received amputation treatment and eleven patients received a bypass operation. The agreement between the preoperative plan based on MD-CTA and the final operation was 100%, even in critical limb ischemia. There were no serious complications related to the tests. CONCLUSION: These findings suggest that MD-CTA is an adequate preoperative imaging study of infrainguinal arterial surgery and may be substituted for conventional angiography without any serious complications.

OBJECTIVE: The purpose of this study was to evaluate any improvement in the quality of abdominal CTs after the utilization of the nationally based accreditation program. MATERIALS AND METHODS: Approval was obtained from the Institutional Review Board, and informed consent was waived. We retrospectively analyzed 1,011 outside abdominal CTs, from 2003 to 2007. We evaluated images using a fill-up sheet form of the national accreditation program, and subjectively by grading for the overall CT image quality. CT scans were divided into two categories according to time periods; before and after the implementation of the accreditation program. We compared CT scans between two periods according to parameters pertaining to the evaluation of images. We determined whether there was a correlation between the results of a subjective assessment of the image quality and the evaluation scores of the clinical image. RESULTS: The following parameters were significantly different after the implementation of the accreditation program: identifying data, display parameters, scan length, spatial and contrast resolution, window width and level, optimal contrast enhancement, slice thickness, and total score. The remaining parameters were not significantly different between scans obtained from the two different periods: scan parameters, film quality, and artifacts. CONCLUSION: After performing the CT accreditation program, the quality of the outside abdominal CTs show marked improvement, especially for the parameters related to the scanning protocol.

Propofol (2,6-diisopropylphenol) is an ultrashort-acting sedative agent with sedative and amnestic effects that is used not only for anesthesia but also for sedation during minor outpatient procedures and endoscopic examinations. Rare cases of anaphylaxis following propofol administration have been reported in the medical literature. Documentation of anaphylaxis is often lacking because the cause and effect relationship is often hard to prove. Only a minority of patients get referred for allergy testing to confirm the offending drug. Here we report a 74-year-old woman who had an anaphylactic reaction with severe oropharyngeal edema and bronchospasm for a few minutes after receiving propofol during endoscopic examination. An allergy skin test was positive for both propofol and soybean. Soybean in the intralipid is one component of propofol, and we concluded that this anaphylaxis was caused by soybean.

Purpose: Minimally invasive surgery (MIS) is currently the standard treatment for rectal cancer. However, its limitations include complications and incomplete total mesorectal resection (TME) due to anatomical features and technical difficulties. Transanal TME (TaTME) has been practiced since 2010 to improve this, but there is a risk of local recurrence and intra-abdominal contamination. We aimed to analyze samples obtained through lavage to compare laparoscopic TME (LapTME) and TaTME. Methods: From June 2020 to January 2021, 20 patients with rectal cancer undergoing MIS were consecutively and prospectively recruited. Samples were collected at the start of surgery, immediately after TME, and after irrigation. The samples were analyzed for carcinoembryonic antigen (CEA) and cytokeratin 20 (CK20) through a quantitative real-time polymerase chain reaction. The primary outcome was to compare the detected amounts of CEA and CK20 immediately after TME between the surgical methods. Results: Among the 20 patients, 13 underwent LapTME and 7 underwent TaTME. Tumor location was lower in TaTME (7.3 cm vs. 4.6 cm, P=0.012), and negative mesorectal fascia (MRF) was more in LapTME (76.9% vs. 28.6%, P=0.044). CEA and CK20 levels were high in 3 patients (42.9%) only in TaTME. There was 1 case of T4 with incomplete purse-string suture and 1 case of positive MRF with dissection failure. All patients were followed up for an average of 32.5 months without local recurrence. Conclusion CEA and CK20 levels were high only in TaTME and were related to tumor factors or intraoperative events. However, whether the detection amount is clinically related to local recurrence remains unclear.
