ABSTRACT

We present a 45-year-old man with chronic pancreatitis and the rare complication of large subcapsular splenic pseudocyst. He suffered from a slow growing left upper quadrant abdominal distension for 2 weeks and pain radiating to his back. On abdominal computed tomography, large subcapsular splenic pseudocyst (25x13x11 cm), multiple small sized pancreatic pseudocysts in the pancreas tail and chronic pancreatitis with multiple pancreatic stones were shown. He underwent percutaneous catheter drainage of the splenic pseudocyst and after 3 weeks, the size of the pseudocyst decreased. But, the pain radiating to his back and poor oral intake was not improved. Distal pancreatectomy, Roux-en-Y pancreaticojejunostomy, and splenectomy were performed and the patient was discharged after 2 weeks. A splenic subcapsular pseudocyst resulting from pancreatitis may be managed by percutaneous drainage, but according to a patient's clinical symptoms, operative management can be added.

ABSTRACT

Forme fruste choledochal cyst (FFCC) is one of the diverse types of choledochal cyst with little or no dilatation of the extrahepatic bile duct (EHBD). It is considered that FFCC has to do with the pancreatobiliary malunion (PBM). In children, 3 to 6 millimeters of EHBD is assumed to be normal. Even though there is no clear-cut definition, FFCC is likely to be associated with bile duct dilatation less than 10 millimeters. Almost all cases have PBMs and symptoms of the pancreatitis or cholangitis. We experienced a case of FFCC in a 4-year-old boy. His EHBD measures 10mm diameter. He had symptoms of pancreatitis and elevated hepatic transaminases. The pancreatobiliary common channel was 28 millimeters. He underwent EHBD resection and Roux-en-Y hepaticojejunostomy and was discharged with no specific complications.

ABSTRACT

Since astrocytes were shown to play a central role in maintaining neuronal viability both under normal conditions and during stress such as ischemia, studies of the astrocytic response to stress are essential to understand many types of brain pathology. The microarray system permitted screening of large numbers of genes in biological or pathological processes. Therefore, the gene expression patterns in the in vitro model of astrocytes following exposure to oxygen-glucose deprivation (OGD) were evaluated by using the microarray analysis. Primary astrocytic cultures were prepared from postnatal Swiss Webster mice. The cells were exposed to OGD for 4 hrs at 37 degrees C prior to cell harvesting. From the cultured cells, we isolated mRNA, synthesized cDNA, converted to biotinylated cRNA and then reacted with GeneChips. The data were normalized and analyzed using dChip and GenMAPP tools. After 4 hrs exposure to OGD, 4 genes were increased more than 2 folds and 51 genes were decreased more than 2 folds compared with the control condition. The data suggest that the OGD has general suppressive effect on the gene expression with the exception of some genes which are related with ischemic cell death directly or indirectly. These genes are mainly involved in apoptotic and protein translation pathways and gap junction component. These results suggest that microarray analysis of gene expression may be useful for screening novel molecular mediators of astrocyte response to ischemic injury and making profound understanding of the cellular mechanisms as a whole. Such a screening technique should provide insights into the molecular basis of brain disorders and help to identify potential targets for therapy.

ABSTRACT

Herein, two cases of acute arterial thrombosis associated with hyperhomocysteinemia are reported. A 34-year old male patient without heart disease, was brought to hospital with an acute ischemic limb due to thromboses of both superficial femoral arteries, where no atherosclerotic lesions were found. Subsequent investigation revealed that the patient had hyperhomocysteinemia, with a low folic acid level. Catheter directed thrombolysis was attempted, but failed, so bypass surgery was performed. After revascularization, anticoagulation therapy and folate supplementation were initiated. His plasma homocysteine level returned to normal, and there has been no recurrence during the 48 month follow up periods. The other case was a 51-year man with an acute left ilio-femoro-popliteal artery occlusion, who had also shown hyperhomocysteinemia, with a low folic acid level. There was nothing abnormal from his medical records, and showed normal findings in his transesophageal echocardiogram. In a serologic hypercoagulability test, everything was normal, with the exception of an increased homocysteine level. After a successful thrombectomy with a Fogarty catheter, folate supplementation was administered until his homocysteine level returned to normal. In both patients, the heterozygous mutation of 5, 10-methylenetetrahydrofolate reductase (MTHFR), C677T (alanine to valine substitution), was detected.

ABSTRACT

PURPOSE: The purpose of this study is to measure the diameter of saphenofemoral junction (SFJ) by using duplex scan and to assess the different anatomic characteristics of SFJ according to the clinical manifestation. METHODS: 100 Limbs of 77 patients with varicose veins due to greater saphenous vein (GSV) were assessed prospectively about sex, symptom, disease duration, morphology of varicose vein. The diameter of GSV (GSVD), SFJ, femoral vein (FVD) and the ratio of each value-GSV/FV (GFDR) and SFJ/FV (JFDR)-were measured by color-flow duplex scanning. Findings were compared with clinically normal 20 control limbs. RESULTS: The mean value of GSVD, FVD, SFJ, GFDR, JFDR in patients group were different from that of control group with statistical significance except FVD. There were statistically significant differences in the mean value of GSVD, FVD, GFDR, JFDR between men and women. The mean value of GSVD, FVD, SFJ, GFDR, JFDR between symptomatic and asymptomatic group were not different statistically. The result of comparison according to the disease duration showed statistically significant difference, which the more duration of disease were longer, the more the mean value of SFJ were increased. In comparison of the findings according to the morphologic classification, there were no statistically significant differences in the mean value of GSVD, FVD, SFJ, GFDR, JFDR. CONCLUSION: Dilatation of SFJ may be related to the cause of varicose veins from the result that the mean value of SFJ was more increased in patients group than control group.

ABSTRACT

PURPOSE: Virtual colonoscopy (VC) is a newly developing non-invasive technique used to detect polyps and cancers of the colon. The aim of this study is to assess the efficacy of VC in the detection of synchronous polyps or cancers in preoperative patients as well as metachronous polyps of postoperative colorectal cancer patients. METHODS: Both VC and conventional colonoscopy (CFS) were performed on 40 patients with colorectal cancer (10 cases of preoperative state and 30 cases of postoperative follow-up) during Sep. 2002 to June 2003 in Daegu Catholic Medical Centre, Catholic University of Daegu, Republic of Korea. The success rate and the detection rate of polyps or cancers along with the locations and sizes of masses and the findings of anastomotic site were compared between VC and CFS. RESULTS: The entire colon was clearly visualized by CFS in all cases. In the preoperative group, VC was successfully performed in 8 out of 10 cases (80%). 8 out of 10 cancers, 4 out of 4 polyps (5 mm or more in diameter) and 3 out of 6 polyps (5 mm or less in diameter) were identified. The success rate of VC in the postoperative group were 58% of low anterior resection (LAR) from cecum to hepatic flexure, 89% of LAR, 45% of right hemicolectomy (RHC) from hepatic flexure to splenic flexure, 63% of LAR, 45% of RHC from splenic flexure to sigmoid colon, and 53% of LAR, 72% of RHC in rectum. The causes of failure were inadequate bowel distension and retained fluid. In postoperative group, VC identified only 3 of 7 polyps(5 mm or more in diameter), 1 of 10 polyps (5 mm or less in diameter) and 1 of 1 recurrent cancer. The anastomotic site was clearly seen by VC in 9 of 19 cases (47%) of LAR and 3 of 11 cases (27%) of RHC. VC also identified 28 extracolonic findings. CONCLUSIONS: Although the efficacy of VC in postoperative colorectal cancer follow up seems to be disappointing, but it can be used as an alternative method for patients with incomplete conventional colonoscopy due to anastomotic site stricture or for other failed cases. Further technological advancement of VC is needed in order for it to replace conventional colonoscopy as a postoperative follow-up test.

ABSTRACT

PURPOSE: Catheter directed thrombolytic dissolution (CDT) of deep vein thrombus (DVT) is in widespread use, yet the complications especially pulmonary embolism (PE), associated with the procedure remains ill defined. To assess the incidence of PE we reviewed the clinical course of acute DVT patients treated by CDT. METHOD: From January 2000 to September 2003, 25 patients were treated by CDT. To define the new development of PE, patients had a technetium 99m lung scan before and just after CDT-, and clinical symptoms were recorded. All patients underwent ascending venogram and CT scan initially to define DVT extension. CDT with urokinase was done by a the same intervention radiologist. RESULT: Proximal thrombus extension level was the femoral vein in 8 patients, iliac vein in 12-, and inferior vena cava (IVC) in 5. Complete thrombolysis was achieved in 16 patients, partial lysis in 2 and no lysis in 7. PE was detected in 7 patients with initial lung scan whose thrombus proximal level was IVC 2, iliac vein 4, femoral vein 1 in each, and no changes in lung scan after CDT. In 17 patients with normal findings at intial lung scan, there were also no changes after CDT. One patient with normal lung scan showed high probable scan defects in lung scan after CDT. Because he also complained of sudden onset dyspnea with cough, we diagnosed him as newly developed, PE-related CDT. CONCLUSION: Only one (4%) case of PE was developed in our study. No prediction factor of PE such as CDT results, or thrombus proximal extent could be defined. These findings suggest that routine usage of temporary IVC filter is unnecessary during CDT.

ABSTRACT

PURPOSE: To assess the suitability of multidetector row CT angiogram (MDCTA) as the sole preoperative imaging for infrainguinal arterial surgery. METHOD: From March 2002 to September 2003, 75 patients (24 claudicants, 41 limb-threatening ischemia) were studied with MDCTA preoperatively. We compared the surgical inflow and outflow site changes between preoperative planning based on MDCTA and the results of final operation. MDCTA was interpreted by the same vascular surgeon, and arterial segments from the renal artery to foot were reviewed. Surgery plans were formulated based on arterial anatomic and hemodynamic characteristics. Additional diagnostic value and test related complications were also studied. RESULT: Twenty- one patients had conventional angiogram after MDCTA scan - 9 for interventional treatment at inflow site and 12 patients for complement of MDCTA, although the operation plan was not changed. The agreement between preoperative plan based on MDCTA and final operation was 100% even in critical limb ischemia. In 11 patients tortuous calcified iliac artery was ambiguous in routine image but it could be solved using the other specific functional option of MDCTA. There were no serious complications related to the test. CONCLUSION: These findings suggest that MDCTA is an adequate preoperative imaging study of infrainguinal arterial surgery and that it may be substituted for conventional angiogram without any serious complication. The particular functional options of MDCTA help resolve its defect.

ABSTRACT

PURPOSE: Although popliteal artery injuries are uncommon, the consequent lack of management protocols may contribute to the high level of outcome morbidity. METHOD: We retrospectively reviewed the records of popliteal artery trauma treated at our institution in the past 5 years. RESULT: In 15 patients [male 13, female 2, median age 45.9 (15-73)] there were 13 cases of blunt trauma, mainly motorcycle accident. Most patients presented with severe signs of ischemia when they arrived at the emergency unit. Most commonly skeletal injury was accompanied (fracture 13, nerve injury 7). Some delays occurred between injury and treatment in every cases. Bypass using the contralateral long saphenous vein was the predominant procedure for arterial injury. Our limb salvage rate was 66.7% (10/15), but all patients needed more than two additive operations, and finally had persistent neurologic disability. CONCLUSION: Popliteal artery injury, especially in Korean urban society, was mainly caused by blunt trauma from traffic accidents and the results remain challenging.

ABSTRACT

PURPOSE: Paradoxical puborectalis contraction (PPC) or Anismus is known to have a pathogenesis of abnormal contraction of puborectalis at defecation and its managements are not satisfactory. Recently, therapy of PPC and its associated symptoms using Botulinum toxin-A (BTX-A) has been introduced. we evaluate the effect of BTX-A injection to the puborectalis for the patients with PPC. METHODS: Fourteen patients were diagnosed as paradoxical puborectalis contraction on defecography and/or anorectal manometry and electromyography (EMG) during September 1998 to January 2001 in Daegu Catholic Medical Centre, Catholic University of Daegu. All patients were underwent 30 (15 15) units of BTX-A injection on each side of puborectalis guided by EMG. Among them, five patients needed further injection of 20 (10 10) units because the expected results were not satisfied. Follow-up were conducted on one month and one year after BTX-A injection and the patients were assessed for the constipation score and anorectal manometry. RESULTS: After injection of BTX-A, constipation score was significantly decreased from 15.5 +/- 3.5 (mean SD) to 5.7 +/- 4.3. Maximal resting and squeezing pressure also decreased from 48.4 +/- 22 mmHg, 96.9 +/- 39.8 to 41.2 +/- 17, 68.3 +/- 38.2, respectively. Twelve patients who were followed up more than one year after injection, the constipation score (n=12) increased up to 7.7 +/- 2.9 (mean SD). Among them, three patients have had stool softeners or laxatives to evacuate and the remained nine patients did not have any kinds of drug or food for defecation. There was no complication for the injection BTX-A. CONCLUSIONS: BTX-A injection seems to be effective for the treatment of PPC and the long term therapeutic effect can be defined through double blind placebo-controlled trials.

ABSTRACT

PURPOSE: Photodynamic therapy (PDT) is a relatively new technology for an alternative modality in the treatment of colorectal cancers. This study was conducted to identify the appropriate dosage and energy level for the photosensitizer as well as effect of PDT on colon cancer cells. METHODS: Colon cancer cell line, COLO 205 (American Type Culture Collection, ATCC) was obtained from Korea Cell Line Bank (KCLB, Seoul, Korea). Cells were cultured on RPMI 1640 medium with 10% fetal calf serum, penicillin, and gentamicin. Cells were incubated at 37 C in a 5% CO2 air environment. Photosense (sulphonated aluminum phthalocyanine, AlPcS4, NIOPIK, State Research Center, Moscow, Russia) was used for the photosensitizer and Fireplace video-3 (Biospec, General Physics Institute, Moscow, Russia, 500 mW/cm2, 670 nm) was used for the light source. 1 104 cells were incubated in 96 well plates with different concentrations of aluminum phthalocyanine: 0.1, 0.3, 0.5 and 1micrometer for 24 hours then photoirradiation was performed at either 24 or 48 J/cm2. The time variations of the viabilities of cells of the four study groups and were measured by using MTT assay according to time were compared to those of the three control groups: control (no treatment), control (AlPcS4, no light), control (light, no AlPcS4), and the study groups (PDT) at one hour, 24 hours, 48 hours and 72 hours after PDT. RESULTS: At, one hour after PDT, the viability of the cells was not changed in the control groups. Viabilities of 117, 40, 35, and 23% in the 24 J group and 76, 31, 52, and 48% in 48 J group were observed, respectively in order of increasing concentration with the value of 87~103% for the control group. 24 hours later, viability of control groups were not changed, By 24 hour after PDT, the viabilities of the control groups had not changed, but those of the 24 J/cm2 and 48 J/cm2 PDT study groups had decreased significantly to 62, 17, 16, and 18% and 24, 15, 13, and 13%, respectively (P=0.00). By 48 hours viability of the 24 J/cm2 and 48 J/cm2 PDT study groups were also significantly decreased being 103, 26, 13, and 13% and 50, 8, 8, and 9%, respectively (P=0.00). By 72 hours, viabilities were 84, 21, 21, and 30 % and 33, 20, 33, and 15%, respectively (P=0.00). CONCLUSIONS: The PDT groups showed a marked cytotoxic effect compared to the control groups, and the effect appeared just after PDT and peaked in 48 hours. The minimum required concentration of the photosensitizer for effective cytotoxicity was at 0.3 micrometer either 24 or 48 J/cm2.

ABSTRACT

PURPOSE: Telomerase activity is generally absent in primary cell cultures and normal tissues. Telomerase is known to be induced upon immortalization or malignant transformation of human cells. Telomerase activity can be increased in immature lymphocytes and activated lymphocytes, but it is not detected in the peripheral blood of normal persons. The authors analyzed peripheral blood telomerase from patients of gastric cancer to evaluate the possibility of using it for diagnosis and as a prognostic factor. MATENRIALS AND METHODS: We obtained blood samples from 11 inflammatory patients and 64 gastric cancer patients. The telomerase activity was measured using the [PCR-ELISA] method. The results were correlated with the T, N, M stage, cell differentiation, vascular, neural, and lymphatic invasion, tumor size, and tumor location. RESULTS: In the 11 inflammatory patients, telomerase activity was not detected while in the gastric cancer patients, a positive rate of 28.1% was noted. The peripheral telomerase activity was not related with tumor size, tumor site, lymphatic and vascular invasion, stage, or histologic differentiation. CONCLUSION: The peripheral blood telomerase activity for patients of gastric cancer can be utilized as a marker for the diagnosis of not only advanced gastric cancer, but also relatively early stage gastric cancer, but not as a prognostic factor.

ABSTRACT

We report various causes of acute abdominal aortic occlusion, a condition which is infrequent but usually ends catastrophically. The three cases are embolic occlusion by myxoma, thrombotic occlusion of aortic aneurysm, and thrombosis of an atherosclerotic aorta; the first two causes are very rare clinical presentations. All patients showed leg paralysis, pain, and severe ischemic symptoms. Diagnosis was done by emergent-CT (computed tomography) scan and surgery was performed urgently. Nevertheless, all patients died in the early postoperative period. As acute aortic occlusion is infrequent, its diagnosis may be delayed. The mortality rates remains high even with urgent surgical care.

ABSTRACT

PURPOSE: We report our early experience, and the feasibility, of an endovascular technique for treating iliac vein compression syndrome, which is known to be caused by a chronic pulsating irritation of the iliac artery. METHODS: Five patients presented with acute deep vein thromboses in their left legs, diagnosed by computed tomography (CT), and treated with a catheter-directed thrombolysis. The residual stenosis was treated by angioplasty, followed by stent placement. The results were evaluated, followed with duplex ultrasound. RESULTS: The CT scan of the left iliac vein was compressed by the right iliac artery, with the thrombosis shown distal of the venous segment of the crossover point in all five cases. Success with the endovascular technique was achieved in all 5 patients. In the follow up, the duplex scan stent site and patency were examined. During the follow up period all the stents were patent, and no thrombosis recurred. CONCLUSION: A CT scan is helpful in diagnosing iliac vein compression syndrome, with a thrombosis. The endovascular approach for its treatment should be considered affirmative due to its safety and simplicity.

ABSTRACT

Scoliosis describes a lateral curvature of the spine and is often associated with cosmetic and functional impairments due to severe deformity of the spine. The incidence of adolescent scoliosis is 2-4% of children between 10 and 16 years of age. Eighty five percent of them are idiopathic, in which the most common type of scoliosis is right side-bending. In addition, it is classified into congenital, and secondary scoliosis such as neuromuscular disease and neurofibromatosis. Congenital scoliosis is associated with abnormalities of urinary system(20%), congenital heart diseases(15 %), and other abnormalities(10%) such as syringomyelia. We experienced a case of scoliosis by a foreign body(a pencil) in the colon which has never been reported up to date. A brief review of the literature was made.

ABSTRACT

PURPOSE: Free cancer cells in the peritoneal cavity exfoliated from a tumor are considered to be responsible for peritoneal dissemination in gastric cancer. To detect free cancer cells, a carcinoembryonic antigen (CEA) was introduced to the marker of gastric cancer. The clinical significance of detecting the carcinoembryonic antigen (CEA) mRNA in the peritoneal fluid was evaluated by RT-PCR in patients with gastric cancer. METHODS: In 50 patients with gastric cancer who received a gastrectomy, the peritoneal washing fluids were obtained and the CEA mRNA was detected by RT-PCR and a cytological examination was taken, simultaneously. The results were correlated with the stage and the recurrence of peritoneal seeding. RESULTS: Positive values of CEA mRNA from the peritoneal washing fluids were observed in 24% (12/50) of patients with gastric cancer but of 4% (2/50) showed peritoneal cytology. There were 8 cases of peritoneal seeding in the follow-up and 6 cases of them presented positive CEA mRNA values (50%, 6/12). According to the stage, positive CEA mRNA values from the peritoneal washing fluids were found in 9% (2/21) in stage I, 20% (2/10) in stage II, 33% (5/15) in stage III and 75% (3/4) in stage IV (P=0.030). In the T classification, positive CEA mRNA values were found in 13% (2/15) in T1, 10% (1/10) in T2, 30% (7/23) in T3 and 100% (2/2) in T4 (P=0.031). In the N classification, positive CEA mRNA values were found in 15% (4/26) in N0, 20% (3/15) in N1, 40% (2/5) in N2 and 75% (3/4) in N3 (P=0.055). CONCLUSION: These results suggest that the detection of CEA mRNA by RT-PCR in peritoneal fluid of gastric cancer patients was more sensitive than the peritoneal cytology, and may have a role in selecting patients with a poor prognosis who may benefit from adjuvant therapy.

ABSTRACT

PURPOSE: The severe combined immunodeficient (SCID) mice which lack the functional T and B lymphocytes have been widely used for the research of various human diseases including AIDS, transplantation, autoimmune disease and cancer. The purpose of this study was to evaluate the huPBMC-SCID mouse as an animal model for human breast cancer research. METHODS: 5x10(7) human PBMC (peripheral blood mononuclear cell) were injected intraperitoneally in 18 SCID mice. After 24 hours, 2.5x10(6), 5x10(6) and 10x10(6) MCF-7 human breast cancer cells were innoculated subcutaneously in the right flank of each of the 3 groups of 6 huPBMC-SCID mice. RESULTS: 4 subcutaneous ecchymosis (2 perioral area, 2 scalp), 1 splenomegaly and 1 hepatic embolism were found during the 20 weeks after the injections. The growth of tumor xenograft was identified in 14 of the total 18 huPBMC-SCID mice, and the growth rate of the tumor was proportional to the number of the innoculated cancer cells. Distant metastases were found in the retroperitoneum, kidney, pelvic cavity, omentum, perisplenic area and regional lymph node in 50 % of mice, but not in the lung and liver at 20 weeks. CONCLUSION: In summary, the huPBMC-SCID mouse was expected to play an important roles as an animal model of human cancers including breast cancer.

ABSTRACT

Infantile hypertrophic pyloric stenosis (IHPS) a common childhood disorders characterized by nonbilious projectile vomiting, an olive shaped mass in the right upper quadrant of the abdomen and visible gastric peristaltic wave in the upper abdomen. Its etiology and pathogenesis are not clear but abnormal nerve distribution of the pylorus has been postulated2-6. We performed immunocytochemical staning to the pyloric muscle from 10 IHPS and 3 controls patients, utilizing specific monoclonal antibody to NCAM(neural cell adhesion molecule). In IHPS patients, the number of NCAM protein immunoreactive nerve fibers were less than that in normal subjects. Auerbach myenteric plexuse was well developed and interbundle nerve plexuse was present but nerve fibers supplying individual muscle cells in smooth muscle bundles were poorly developed. These results indicate reduction of innervation in smooth muscles in IHPS patients that possibly contributes to the pathogenesis of IHPS.

PURPOSE: The advanced stage of chronic venous insufficiency (CVI) 4, 5, 6, which shown lipodermatosclerosis, venous ulcer might cause frustrating symptom compared with simple varicose vein. For successful treatment, precise anatomic, hemodynamic information of venous system is recommended. Although there is still controversy, duplex scan is the best way in evaluation of hemodynamic pathology. We studied key role of duplex scan in treatment of advanced CVI. METHOD: From November 1998, to February 2000, 125 patients were treated for CVI in our hospital. Of these 11 patients with class 4, 5, 6 were assessed by duplex scan, ascending venogram, hemodynamic functional studies. All venous segments were eagerly assessed for looking reflux. Except one patient who refuse surgery 10 patients received conventional surgical treatment and endoscopic perforator ligation. The one year follow up results were assessed. RESULT: 9 patients showed superficial venous reflux, 3 patients had deep venous reflux. In all 6 patients who had ulcer, incompetent perforator vein was identified. In 9 patients, stripping 8, high ligation 1, endoscopic perforator vein ligation 3 were done. During 1 year follow up clinical improvement was singificant in these 11 patients assessed with symptom scores. All ulcer were healed with average 25.3 days, and no recurrence. CONCLUSION: Although no single test was enough for perfect assessing CVI, scrupulous examination with duplex scan is best way for accomplishing successful outcome at presents.

ABSTRACT

PURPOSE: Gallstone disease has been presumed to be a sequellae of gastrectomy. To know correlation between gallbladder disease and gastrectomy, we check anatomical and functional status of gallbladder with ultrasonogram in our study. METHODS: Gallbladder motility after gastrectomy was studied by means of measuring fasting and postprandial gallbladder volume using real time ultrasonography in 50 gastrectomized patients and in 28 controls (healthy but not operated gastric cancer patients) were selected as study subjects. RESULTS: Mean fasting and postprandial gallbladder volume was significantly increased in gastrectomized patient group (FV: 37.63+/-20.70 ml, PV: 11.50+/-10.26 ml) than control group (FV: 22.17+/-10.35 ml, PV: 5.44+/-3.67 ml, p<0.01). The ejection fraction of gallbladder in gastrectomized patient group (69.05+/-14.57%)was significantly smaller than control group (75.57+/-10.26%, p<0.05). CONCLUSION: The risk of gallbladder disease was independent of age, sex, and post-operative duration in our study. Gastrectomy may have the possibility of increasing the risk of gallbladder disease by causing gallbladder dysmotility and bile stasis. So, gallbladder motility evaluation would be helpful for prevention and understanding gallstone formation. Further study will be needed about the clinical benefits of prophylactic cholecystectomy during gastrectomy.
