ABSTRACT

Purpose@#The present study was performed to investigate the effects of local complications (LC) on long-term survival and cancer recurrence in patients undergoing curative gastrectomy for gastric cancer. @*Methods@#We analyzed 2,627 patients after curative gastrectomy for gastric cancer between January 2001 and December 2006. Patients were classified into groups no complications (NC), LC, or systemic complications (SC). @*Results@#Among the 2,627 patients, 475 patients developed complications (LC group [n=374, 14.2%] and SC group [n=101, 3.9%]). The 5-year cancer-specific survival rate was significantly poorer in the LC group compared to the NC and SC groups (LC, 78.0%; NC, 85.4%; SC, 80.2%; P=0.007). The occurrence of LC was identified as a significant independent prognostic factor for overall and cancer-specific survival (hazard ratio [HR], 2.08; 95% confidence interval [CI], 1.46–2.97; P=0.001 and HR, 1.77; 95% CI, 1.12–2.81; P=0.015). The tumor recurrence rates were higher in the LC group than the in other two groups (LC, 23.5%; NC, 15.4%; SC, 15.8%; P<0.001). The occurrence of LC was an independent predictor of tumor recurrence in patients undergoing curative gastrectomy for gastric cancer (HR, 1.55; 95% CI, 1.11–2.17; P=0.011). @*Conclusion@#LC are associated with adverse long-term outcomes in patients after curative gastrectomy for advanced gastric cancer.

ABSTRACT

Purpose@#The present study compares the peri/postoperative and oncological outcomes of abdominoperineal resections (APR) and sphincter saving resection (SSR) for low lying rectal cancer. @*Methods@#Between January 2001 and December 2014, 176 patients who underwent SSR (n = 67) and APR (n = 109) for low rectal cancer, without stage IV, were retrieved from a retrospective database. @*Results@#With a median follow-up of 66.5 months. The mean total number of harvested lymph nodes was 16.7 (SSR) versus 17.1 (APR) (P = 0.801). The advanced T stage was higher in the APR group (82.6%) versus the SSR group (55.2%) (P = 0.006). The positive rate of lymph nodes after surgery was significantly higher in the APR group (45.9%) versus SSR group (25.4%) (P < 0.05). The 5-year overall survival rates for SSR and APR were 87.3% and 67.6%, respectively (P < 0.005). The 5-year disease-free survival rate (DFS) was 83.6% (SSR) versus 65.5% (APR) (P = 0.002). The recurrence rate was higher in the APR group (34.9%) versus the SSR group (14.9%) (P = 0.004). Local recurrence rate was not different between the two groups. However, distant recurrence rate was significantly higher in the APR group (26.6% vs. 11.9%, P = 0.023). In multivariate analysis, node positive (N0 vs. N1-2) was an independent prognostic factor for DFS (P < 0.005). @*Conclusion@#Based on the present data, SSR achieved better 5-year oncological outcome than APR. The positive lymph node ratio in the N stage after surgery was higher in the APR group and this seems to have an effect on the oncological outcomes of the APR group.

ABSTRACT

PURPOSE: Emerging evidence indicates that runt-related transcription factor 3 (RUNX3) is an important tumor suppressor gene in several cancer types, including colorectal cancer (CRC). However, the clinical significance of RUNX3 inactivation in CRC remains unclear. The aim of this study was to examine the correlation between clinicopathologic factors and RUNX3 hypermethylation/expression in CRC. METHODS: Sixty-two CRC patients who were treated at the Soonchunhyang University College of Medicine were recruited in this study. The hypermethylation of CpG islands in the RUNX3 promoter and the expression of RUNX3 mRNA were identified by methylation-specific polymerase chain reaction (PCR) and reverse transcriptase-PCR, respectively. The expression of RUNX3 was determined by immunohistochemical staining. RESULTS: Of the 62 CRC tissue samples, 20 (32.3%) presented hypermethylated RUNX3 promoters. Aberrant RUNX3 hypermethylation was found to be associated with vascular (P = 0.006) and lymphatic (P = 0.002) invasion. Hypermethylation of RUNX3 was associated with poor survival outcomes (P = 0.038). However, expression of RUNX3 was not a prognostic factor (P = 0.363). CONCLUSION: Hypermethylation of RUNX3 may be a predictor of a poor prognosis in CRC.

ABSTRACT

Small bowel lymphangioma is a rare benign tumor of the lymphatic system, characterized by the presence of dilated lymphatic spaces and significant gastrointestinal bleeding. Small bowel lymphangiomas are rare in adults and case reports are few. Lymphangiomas in the jejunum or ileum are extremely rare and account for less than 1% of all lymphangiomas. The case reported herein is of an older patient (70-year-old male) with melena and chronic anemia (hemoglobin count < 5 g/dL) who had small-sized multiple lymphangiomas in his small bowel (jejunum). Surgical resection was performed after failure of treatment by gastroenteroscopy. Final pathological analysis revealed lymphangioma with thrombus and hemorrhage. After surgery, he no longer had decreased hemoglobin count, nor symptoms of anemia and melena. Also, at the last follow-up visit, the patient's hemoglobin count patient was normal and he returned to normal daily functions.

ABSTRACT

PURPOSE: The study aimed to analyze peri/postoperative outcomes and long-term oncologic outcomes after surgical management for primary gastrointestinal diffuse large B-cell lymphoma (DLBL).METHODS: Between January 2001 and December 2013, 19 patients who underwent surgery for primary gastrointestinal DLBL were retrieved from a retrospective database.RESULTS: With a median follow up of 49.2 months, the most common tumor locations were the terminal ileum and cecum (n=14, 73.7%) and stomach (n=4, 21.1%). The most common clinical symptoms were abdominal pain (n=15, 78.9%) and intussusceptions (n=5, 26.3%). None of the patients had B symptoms. Emergency surgery was undertaken in 36.8% (n=7) of the patients. Mean mass size was 8.4 cm; 4 patients (21.1%) had a bulky mass (>10 cm). The International Prognostic Index (IPI) scores were low (n=11, 57.9%), low-intermittent (n=7, 36.8%), and high-intermittent (n=1, 5.3%). Patients' staging was IE (n=9, 47.4%), IIE (n=8, 42.1%), and IVE (n=2, 10.5%) based on the Ann Arbor staging system, and I (n=2, 10.5%), II1 (n=5, 26.4%), IIE (n=10, 52.6%), and IV (n=2, 10.5%) based on the Lugano staging system. B-lymphocyte antigen CD20 was positive in most patients (n=17, 89.5%) and Ki-67 was high (>70%) in 12 patients (63.2%). Two types of chemotherapy were administered: cyclophosphamide, hydroxydaunorubicin, oncovin, and prednisolone (n=5, 26.3%), rituximab, cyclophosphamide, hydroxydaunorubicin, oncovin, and prednisolone (n=13, 68.4%). The 5-year disease-free survival rate was 94.4% and the 5-year overall survival rate was 89.5%.CONCLUSION: Surgery for primary gastrointestinal DLBL is feasible and acceptable. Low staging of primary gastrointestinal DLBL has good prognosis.

ABSTRACT

The purpose of this study was to investigate the difference of nutritional status according to metabolic syndrome in colorectal cancer patients. The subjects were divided into 2 groups (metabolic syndrome group and normal group) according to the presence or absence of metabolic syndrome in 143 patients diagnosed with colorectal cancer, and their lifestyle and nutritional status were analyzed. Recall method was used for the dietary survey, and metabolic syndrome was defined as the presence of 3 or more of waist circumference, fasting blood glucose, triglyceride, high-density lipoprotein (HDL)-cholesterol, and blood pressure. This study showed that the metabolic syndrome group had a low age, a high body mass index (BMI), and a high drinking rate. The intake of energy, protein, fat, calcium, and phosphorus was significantly higher in the metabolic syndrome group than in the normal group, and the intake of β-carotene, vitamin C, and folic acid was significantly low. The intake of cholesterol, fatty acid, saturated fatty acid, and polyunsaturated fatty acid was also higher in the metabolic syndrome group. Higher BMI, alcohol consumption, intake of fat, total fatty acid or saturated fatty acid increased the risk of metabolic syndrome, but fiber, vitamin C, or folic acid intake lowered the risk.Weight management and balanced nutritional intake should be emphasized to prevent metabolic syndrome and to improve the condition in patients with colorectal cancer.

ABSTRACT

PURPOSE: The goal of oncoplastic breast surgery is to restore the appearance of the breast and improve patient satisfaction. Thus, the assessment of cosmetic results and patient-reported outcomes (PROs) using appropriately constructed and validated instruments is essential. The aim of the present study was to assess the long-term objective cosmetic results and corresponding PROs after oncoplastic breast surgery. METHODS: Cosmetic results were assessed by the patients, a medical panel, and a computer program (BCCT.core). PROs were assessed using BREAST-Q, a questionnaire that measures the perception of patients having breast surgery. The cosmetic results and PROs were analyzed in patients who underwent quadrantectomy and partial breast reconstruction utilizing the latissimus dorsi flap. RESULTS: The mean duration of the follow-up period was 91.6 months (range, 33.3-171.0 months), and mean age of the patients was 51 years old (range, 33-72 years). The mean tumor size was 2.1 cm (range, 0.9-5.5 cm). There was fair agreement between the medical panel and BCCT.core score (K = 0.32, P < 0.001), and a statistically significant correlation between the BCCT.core score and medical panel cosmetic results was identified (r = 0.606, P < 0.001). A better BCCT.core result was related to a higher PRO of each BREAST-Q domain-satisfaction with breasts (R2 = 0.070, P = 0.039), satisfaction with outcome (R2 = 0.087, P = 0.021), psychosocial well-being (R2 = 0.085, P = 0.023), sexual well-being (R2 = 0.082, P = 0.029), and satisfaction with information (R2 = 0.064, P = 0.049). CONCLUSION: Our long-term results of oncoplastic surgery achieved a high level of patient satisfaction with good cosmetic results. The medical panel and BCCT.core results correlated well with the PROs of the patients using valid, reliable, and procedure-specific measures.

ABSTRACT

PURPOSE: To investigate the treatment outcome and the toxicity of helical tomotherapy (HT) in patients with metastatic colorectal cancer (mCRC). MATERIALS AND METHODS: We retrospectively reviewed 18 patients with 31 lesions from mCRC treated with HT between 2009 and 2013. The liver (9 lesions) and lymph nodes (9 lesions) were the most frequent sites. The planning target volume (PTV) ranged from 12 to 1,110 mL (median, 114 mL). The total doses ranged from 30 to 70 Gy in 10-30 fractions. When the alpha/beta value for the tumor was assumed to be 10 Gy for the biologically equivalent dose (BED), the total doses ranged from 39 to 119 Gy10 (median, 55 Gy10). Nineteen lesions were treated with concurrent chemotherapy (CCRT). RESULTS: With a median follow-up time of 16 months, the median overall survival for 18 patients was 33 months. Eight lesions (26%) achieved complete response. The 1- and 3-year local progression free survival (LPFS) rates for 31 lesions were 45% and 34%, respectively. On univariate analysis, significant parameters influencing LPFS rates were chemotherapy response before HT, aim of HT, CCRT, PTV, BED, and adjuvant chemotherapy. On multivariate analysis, PTV 48 Gy10 were associated with a statistically significant improvement in LFPS. During HT, four patients experienced grade 3 hematologic toxicities, each of whom had also received CCRT. CONCLUSION: The current study demonstrates the efficacy and tolerability of HT for mCRC. To define optimal RT dose according to tumor size of mCRC, further study should be needed.

ABSTRACT

PURPOSE: Total thyroidectomy with central lymph node dissection (CLND) is a treatment modality of choice for thyroid cancer. Hypocalcemia is the most common complication after total thyroidectomy. The aim of the current study was to determine the association between surgery-related clinical factors and postoperative hypocalcemia. METHODS: A prospective analysis was performed for 101 patients who underwent total thyroidectomy with CLND for papillary cancer from June 2013 to June 2014. Correlation between clinicopathologic factors and postoperative hypocalcemia was analyzed. RESULTS: Based on the postoperative day-2 calcium, 56 patients (55%) developed hypocalcemia and 45 patients (45%) were normal. No significant differences in histopathologic (tumor size, tumor focality, histologic type, number of retrieved lymph nodes, metastatic lymph node, thyroiditis, retrieved parathyroid gland) findings were observed between the hypocalcemia group and normal calcium group. Mean value of the postoperative day-0 parathyroid hormone (PTH) was significantly lower in the hypocalcemia group (hypoca1cemia group: 14.3+/-9.4 pg/mL; normal group: 25.0+/-16.4 pg/mL; P<0.001). In logistic regression analysis, postoperative PTH was a factor significantly affecting postoperative hypocalcemia (OR 0.93; CI: 0.90-0.97; P<0.001). In ROC analysis, the cut-off value of PTH was 19.965 (sensitivity 79%, specificity 58%), and area under the curve (AUC) was 0.709 (95% CI: 0.607-0.811). CONCLUSION: Postoperative PTH was a factor predicting hypocalcemia after total thyroidectomy with CLND. Use of postoperative PTH as a screening tool for prediction of postoperative hypocalcemia would be useful in management of patients with hypocalcemia.

ABSTRACT

PURPOSE: Although stromal-cell-derived factor (SDF)-1alpha is suggested to be involved in tumorigenicity and tumor angiogenesis, the clinicopathological significance of its expression in colorectal cancers is not fully understood. We examined SDF-1alpha expression in colorectal cancers and investigated its relationship to clinicopathological features such as tumor staging, lymph-node metastasis, vascular invasion (VI), lymphatic invasion (LI) and neural invasion (NI). METHODS: Specimens of 83 primary colorectal cancers were examined immunohistochemically, and the relationships between clinicopathological features and SDF-1alpha expression were analyzed. To compare the expressions between the normal colon tissue and colorectal cancer tissues, we performed Western blot analyses. RESULTS: According to the Western blot analyses, SDF-1alpha was more highly expressed in colorectal carcinoma tissues than in normal colonic mucosa (20/21). According to the immunohistochemical stain, SDF-1alpha was associated with nodal status, distant metastasis, tumor staging, VI and LI. SDF-1alpha expression had a significant prognostic value for overall survival. Kaplan-Meier plots of survival in patients with high SDF-1alpha showed that high SDF-1alpha expression was associated with a shorter overall survival. However, no association was found between SDF-1alpha expression and other pathologic or clinical variables, including age, gender, degree of differentiation, and presence of perineural invasion. CONCLUSION: The expression of SDF-1alpha might be associated with tumor progression in colorectal cancer. Inhibition of SDF-1alpha could be a therapeutic option in colorectal cancer patients.

ABSTRACT

Rectal prolapse is defined as a protrusion of the rectum beyond the anus. Although rectal prolapse was recognized as early as 1500 BC, the optimal surgical procedure is still debated. The varied operative procedures available for treating rectal prolapsed can be confusing. The aim of treatment is to control the prolapse, restore continence, and prevent constipation or impaired evacuation. In elderly and high-risk patients, perineal approaches, such as Delorme's operation and Altemeier's operation, have been preferred, although the incidence of recurrence and the rate of persistent incontinence seem to be high when compared with transabdominal procedures. Abdominal operations involve dissection and fixation of the rectum and may include a rectosigmoid resection. From the late twentieth century, the laparoscopic procedure has been applied to the treatment of rectal prolapse. Current laparoscopic surgical techniques include suture rectopexy, stapled rectopexy, posterior mesh rectopexy with artificial material, and resection of the sigmoid colon with colorectal anastomosis with or without rectopexy. The choice of surgery depends on the status of the patient and the surgeon's preference.

ABSTRACT

PURPOSE: Wound infection after an ileostomy reversal is a common problem. To reduce wound-related complications, purse-string skin closure was introduced as an alternative to conventional linear skin closure. This study is designed to compare wound infection rates and operative outcomes between linear and purse-string skin closure after a loop ileostomy reversal. METHODS: Between December 2002 and October 2010, a total of 48 consecutive patients undergoing a loop ileostomy reversal were enrolled. Outcomes were compared between linear skin closure (group L, n = 30) and purse string closure (group P, n = 18). The operative technique for linear skin closure consisted of an elliptical incision around the stoma, with mobilization, and anastomosis of the ileum. The rectus fascia was repaired with interrupted sutures. Skin closure was performed with vertical mattress interrupted sutures. Purse-string skin closure consisted of a circumstomal incision around the ileostomy using the same procedures as used for the ileum. Fascial closure was identical to linear closure, but the circumstomal skin incision was approximated using a purse-string subcuticular suture (2-0 Polysorb). RESULTS: Between group L and P, there were no differences of age, gender, body mass index, and American Society of Anesthesiologists (ASA) scores. Original indication for ileostomy was 23 cases of malignancy (76.7%) in group L, and 13 cases of malignancy (77.2%) in group P. The median time duration from ileostomy to reversal was 4.0 months (range, 0.6 to 55.7 months) in group L and 4.1 months (range, 2.2 to 43.9 months) in group P. The median operative time was 103 minutes (range, 45 to 260 minutes) in group L and 100 minutes (range, 30 to 185 minutes) in group P. The median hospital stay was 11 days (range, 5 to 4 days) in group L and 7 days (range, 4 to 14 days) in group P (P < 0.001). Wound infection was found in 5 cases (16.7%) in group L and in one case (5.6%) in group L (P = 0.26). CONCLUSION: Based on this study, purse-string skin closure after a loop ileostomy reversal showed comparable outcomes, in terms of wound infection rates, to those of linear skin closure. Thus, purse-string skin closure could be a good alternative to the conventional linear closure.

ABSTRACT

Since Kalloo and colleagues first reported the feasibility and safety of a peroral transgastric approach in the porcine model in 2004, various groups have reported more complex natural orifice transluminal endoscopic surgery (NOTES) procedures, such as the cholecystectomy, splenectomy and liver biopsy, in the porcine model. Natural orifice access to the abdominal cavity, such as transgastric, transvesical, transcolonic, and transvaginal, has been described. Although a novel, minimally invasive approach to the abdominal cavity is a peroral endoscopic transgastric approach, there are still some challenging issues, such as the risk of infection and leakage, and the method of gastric closure. Hybrid-NOTES is an ideal first step in humans. Human hybrid transvaginal access has been used for years by many surgeons for diagnostic and therapeutic purposes. Here, we report a transvaginal flexible endoscopic appendectomy, with a 5-mm umbilical port using ultrasonic scissors in a 74-year-old woman with acute appendicitis.

ABSTRACT

PURPOSE: Although laparoscopic appendectomy is a safe and effective procedure for the management of acute appendicitis, laparoscopic appendectomy in pregnancy has not been considered the preferred procedure until recently. The aim of this study was to evaluate the safety of laparoscopic appendectomy (LA) during pregnancy as compared with the control group that underwent open appendectomy (OA) during pregnancy. METHODS: The clinical data of all the patients who underwent appendectomy during pregnancy at our hospital between 2006 and 2009 was collected and retrospectively analyzed. Nineteen patients underwent LA and 11 patients underwent OA. The general features of the cases, the outcomes and the fetal status were evaluated. RESULTS: There were no significant differences in the length of the procedure, the hospital stay and the complication rate between the LA and OA groups. All the laparoscopic procedures were completed without conversion to an open operation. There were no significant differences between the two groups for premature delivery, the delivery type and the birth weight. There were no fetal losses or abortions. CONCLUSION: Our results demonstrate that LA was not inferior to OA in terms of the operative outcomes, the complication and both the fetal and maternal safety during 1st and 2nd trimesters of pregnancy. LA could be safely performed even in the 1st and 2nd trimesters of pregnancy using careful patient selection, safe operative techniques and the appropriate application of instruments.

ABSTRACT

We present here a case of recurrent rectal cancer liver metastasis that was managed with ante situm liver resection under total vascular exclusion (TVE) and venovenous bypass with hypothermic perfusion. A 58-year-old man who suffered with rectal cancer liver metastasis was transferred to our hospital in January 2006. A left lateral sectionectomy had been previously performed. Recurrent lesion developed in segments I, IV and VIII one year after the first hepatectomy. The tumor was 5 cm in diameter and it involved the confluence of the hepatic veins and the retrohepatic vena cava. An incomplete tumor-free margin and massive bleeding were expected with performing a conventional liver resection, together with vena cava reconstruction. Therefore, we planned an ante situm liver resection under TVE and venovenous bypass with hypothermic perfusion. After adhesiolysis, hilar dissection was carried out. The inflow to the medial segment was interrupted, and then the liver and inferior vena cava (IVC) were mobilized fully. During controlling the bleeding of a short hepatic vein, we found adhesion of the hepatocaval portion. Therefore, TVE and venovenous bypass were performed along with suprahepatic IVC transection. The long conduit of V5 was preserved during hepatic parenchymal dissection, and the paracaval portion of the caudate lobe was readily detached from the IVC. The suprahepatic IVC was reconstructed after V5 reconstruction with using the saphenous vein. Portal vein anastomosis was then conducted. After reperfusion, an end-to-side anastomosis was performed between the saphenous vein graft and the IVC. Finally, a Roux-en-Y hepaticojejunostomy was carried out. The patient remains well without recurrence 12 months after the last operation.

ABSTRACT

Inflammatory bowel disease, such as ulcerative colitis and Crohn's disease, has a potential risk of developing into colorectal cancer. However, there is little relationship between intestinal tuberculosis and colon cancer because intestinal tuberculosis is a curable disease and has a relatively short disease course. Nevertheless, there have been a few case reports of intestinal tuberculosis associated with colon cancer. There was a case report in which the carcinoma facilitated entry of tubercle bacilli with development of a secondary infection, and ulcerative lesions of tuberculosis may be precursors of carcinomas. We experienced a 77-year-old woman who had intestinal tuberculosis combined with ascending colon cancer. She visited our hospital because of abdominal pain and constipation. Colonoscopy showed a luminal obstruction mass in the ascending colon. Histologic examination revealed an adenocarcinoma. After surgery, the surgical specimen disclosed an adenocarcinoma in the cecum and ascending colon and intestinal tuberculosis around the cancer site of the cecum. Herein, we report a rare case of colon cancer co-existing with colonic tuberculosis with a review of the literature.

ABSTRACT

PURPOSE: The prognosis for patients with liver metastases (LM) from colorectal cancer is significantly influenced by the clinician's decision. Recently, there have been remarkable advances in treatment of LM, so there can be some changes in therapeutic modalities. We performed a comparative study between operated and non-operated groups of patients with LM to analyze the clinical outcome. METHODS: From Feb. 2001 to Feb. 2006, 27 patients with LM underwent a hepatectomy, and 113 patients received non-surgical therapy. thirteen hepatectomized cases among the 27 patients had multiple LM. The outcomes of those 13 patients (Group A) were retrospectively compared to those of the non-operated group (Group B, n=21), which had had potentially resectable LM at the initial diagnosis or after chemotherapy, but didn't undergo hepatic resection. RESULTS: After a median follow-up duration of 31.3 months, the estimated 3-years overall survival (OS) rates were 76.9% and 14.3% in group A and B, respectively (P=0.0001). In the stepwise Cox multivariate regression analysis, factors such as the absence of hepatic resection and a greater diameter of the liver mass independently influenced the poor survival (P=0.005 and P=0.012 respectively). Additionally, two radiologists evaluated the intraoperative ultrasonographic (IOUS) results. IOUS detected new metastatic lesions in 4/13 (30%) patients. There were sub-centimeter metastatic lesions (5~7 mm) and had not been detected in SPIO-enhanced MRI. CONCLUSIONS: Our results compared to palliative chemotherapy suggest that aggressive surgical resection should be performed to increase the survival rate in patients with LM. Additionally, the treatment plan for LM patients should be discussed with the gastroenterololgist, the radiologist, the oncologist, and the surgeon.

ABSTRACT

PURPOSE: Overexpression of the protein tyrosine phosphatase (PRL-3) is elevated in liver metastases derived from colorectal cancer. We examined PRL-3 expression in the primary lesion of colorectal cancer patients and investigated its relation to clinicopathological features. METHODS: A total of 63 randomly selected patients who underwent surgical resection for colorectal cancer between May 2001 and June 2005 at our hospital were investigated. Formalin-fixed and paraffin-embedded specimens from colorectal cancer patients who underwent surgical resections for primary tumors were collected. The expression of PRL-3 was detected by immunohistochemistry and the relation with age, sex, primary tumor size, tumor cell differentiation, depth of invasion, microscopic lymph node metastases, vascular invasion, numbers of lymph node metastases, postoperative stage, and postoperative survival time were analyzed. RESULTS: A total of 16 of the 63 colorectal cancer patients were detected with liver metastases during the follow-up periods. Liver resection was performed for those liver metastases patients. Five patients developed lung metastases after liver resection. PRL-3 expression was detected in 46 colorectal cancer patients. Fourteen patients with lymphatic invasion had positive expression of PRL-3 that was significant (P=0.042). The incidence of PRL-3 expression in the T stage was significant (P=0.019). Moreover, PRL-3 expression was closely associated with liver metastases (P=0.048). CONCLUSIONS: These results indicate that an investigation of PRL-3 expression in primary colorectal cancer lesions may contribute to the detection of occult liver metastases and to a differentiation between postoperative management strategies.

ABSTRACT

PURPOSE: The technique of laparoscopic gastrectomy has developed for early gastric cancer, but a few reports have studied the objective advantages of laparoscopic techniques in a prospective manner. The purpose of this study is to compare laparoscopy-assisted gastrectomy (LG) with conventional open gastrectomy (OG) by the operative outcomes, the recovery of bowel function, and the complications in a prospective nonrandomized manner. METHODS: We studied 73 patients with gastric cancer who were diagnosed as stage I (IA, IB) preoperatively between July 2003 and September 2004. 38 patients underwent LG and 35 patients underwent OG. All patients underwent radical lymphadenectomy (D2), and were treated by a single surgeon. RESULTS: Patients of the two groups were comparable by age, sex, BMI (Body mass index), preoperative stages and mean number of retrived lymph nodes. The mean operative time was shorter in the OG group (P=0.012), and the mean amount of blood loss was significantly less in the LG group than in the OG group (P=0.002). The patients in the LG group recovered bowel function significantly earlier than those in the OG group (P=0.01), thus, the mean hospital stay was significantly shorter in the LG group (P=0.007). The postoperative pain was significantly lower in the LG group (P<0.001). The postoperative complications were 4 cases in the LG group and 6 cases in the OG group, and there were no conversions and no mortalities. CONCLUSION: LG, when compared with OG, has several advantages, including less blood loss, rapid return of gastrointestinal function, less pain, and shorter hospital stay with compromising the cure rate. In addition, for evaluation of the validity of laparoscopic surgery in gastric cancer, a large scaled randomized prospective multicenter study is required.
