PURPOSE: Early gastric cancer (EGC) has an excellent prognosis compared to advanced gastric cancer. The 5-year survival rate for EGC now exceeds 90%, and EGC is recognized as a curable malignancy. The important prognostic factor in EGC is the status of lymph-node metastasis. Despite conserving surgery being suggested for EGC at present, it is of vital importance to select a surgical method appropriate to each individual case. This retrospective study was undertaken to clarify clinicopathologic features and factors related to lymph-node metastasis in submucosal gastric cancer in order to determine an appropriate therapy. MATERIALS AND METHODS: This study analyzed the clinicopathologic features for 279 patients with a submucosal gastric carcinoma (Group I) and compared with those of patients with mucosal (Group II) or muscularis proprial gastric carcinoma (Group III). All patients were operated on from 1981 to 1999 at Chonnam University Hospital. There were no statistically significant differences among the groups with respect to age, gender, tumor location, hepatic metastasis, or peritoneal dissemination. RESULTS: Positive lymph node metastasis was found in 47 (16.8%) of the 279 patients with a submucosal gastric carcinoma. The incidence of lymph-node metastasis was significantly higher in patients with a submucosal gastric carcinoma than in patients with a mucosal gastric carcinoma (16.8% vs. 3.9%; P<0.01). Therefore, depth of invasion was a significant factor affecting in lymph-node metastasis. The 5-year survival rates were 88.6% for patients in Group I, 95.2% for patients in Group II, and 72.7% for patients in Group III (P<0.01 for Group I vs. Group II; Group I vs. Group III). In patients with a submucosal gastric carcinoma, the survival rate with positive lymph nodes was significantly poorer than that of patients without lymph-node metastasis (87.3% vs. 94.2%; P<0.01). CONCLUSION: Gastrectomy with D2 lymph node dissection is an appropriate operative procedure for patients with a submucosal gastric carcinoma.

Although rare, traumatic injuries to the lower rectum and anal sphincter muscle combined with deep perineal laceration present substantial diagnostic and management challenges for surgeons. Between February 2004 and February 2006, six patients were treated for traumatic injuries to the lower rectum and anal sphincter muscle combined with deep perineal laceration at the Department of Surgery, Chonnam National University Hospital. All six patients underwent a diverting colostomy, primary repair, and presacral a drainage, but only three cases underwentva a sphincteroplasty. Three patients who underwent a sphincteroplasty had normal findings on anorectal manometry. Traumatic injuries to the lower rectum and anal sphincter muscle combined with deep perineal laceration have a high morbidity rate and a great influence on the quality of life. Thus, such injuries require aggressive management, and treatment modalities should be tailored to the individual case.

BACKGROUNDS/AIMS: Hepatic resection has only guaranteed long-term survival in patients with colorectal liver metastasis (CRLM) even in the era of effective chemotherapy. The definite role of neoadjuvant chemotherapy (NCT) is to improve outcomes of unresectable CRLMs, but it its role has not been defined for initially resectable CRLMs (IR-CRLMs). METHODS: We reviewed the medical records of 226 patients, who had been diagnosed and treated for IR-CRLM between 2003 and 2008; the patients had the following pathologies: 10% had more than 4 nodules, 11% had tumors larger than 5 cm, and 61% had synchronous CRMLs. Among these patients, 20 patients (Group Y) were treated with NCT, and 206 (Group N) did not receive NCT according to their physician's preference. The median follow-up time was 34.1 months. RESULTS: The initial surgical plans were changed after NCT to further resection in 20% and to limited resection in 10% of 20 patients. Complication rates of Groups Y (30%) were indifferent from Group N (23%) (p=0.233), but intraoperative transfusions were more frequent in Group N (15%) than in Group Y (5%) (p=0.006). There was one case of hospital mortality (0.44%). Disease-free survival rates in Groups Y and N were 23% and 39%, respectively, and patient survival rates were 42% and 66% (p>0.05). By multivariate analysis, old age (> or =60 years), differentiation of primary tumor (poorly/mucinous), resection margin involvement, and no adjuvant chemotherapy were associated with poor patient survival; the number of CRLMs (> or =4) was associated with poor disease-free survival. CONCLUSIONS: NCT had neither a positive impact nor a negative impact on survival, even with intraoperative transfusion, as observed on operative outcomes for patients with IR-CRLM. Further study is required to elucidate the role of NCT for treatment of patient with IR-CRLMs.

PURPOSE: The five-year survival rate is over 95% for radically resected early gastric cancer. The development of diagnostic techniques enables early detection of gastric cancer, so the life expectancy of patients with early gastric cancer is prolonged. Therefore, a limited number of surgeries are performed these days for the purpose of increasing the quality of life. The purpose of this study is to assess the postoperative quality of life after a pylorus-preserving gastrectomy (PPG) compared with that after a subtotal gastrectomy with gastroduodenal anastomosis (B-I). MATERIALS AND METHODS: One hundred seven (107) patients who underwent gastric surgery for early gastric cancer from January 1999 to December 2003 at the Department of Surgery of Chonnam National University Hospital were selected. We compared patients who underwent a PPG with those who underwent a B-I. The clinical results were compared by using the chi-square test and the Student's T-test. The data were considered to be significant when the P value was less than 0.05. RESULTS: Twenty-nine patients (29) underwent a PPG, and the other seventy-eight (78) patients underwent a B-I. There was no significant difference between the two groups on sex, age, and postoperative abdominal symptoms. The patients who underwent a PPG showed shorter operation times and less reflux gastritis and esophagitis on endoscopic evaluation than the patients who underwent a B-I. CONCLUSION: The pylorus-preserving gastrectomy (PPG) is a more physiologic operation than the subtotal gastrectomy with gastroduodenal anastomosis (B-I) and improves the postoperative quality of life.

During recent years, cases of toxic shock syndrome have been reported with increasing frequency in plastic surgery patients. The majority of reports relate to aesthetic plastic surgical procedures such as rhinoplasty, augmentation mammoplasty, liposuction, and chemical peeling. We report a case of toxic shock syndrome with necrotizing fascitis after liposuction in a 23-year-old woman who had erythema and edema, blister formation and gangrene in the skin. The patient was admitted to the intensive care unit, and treatment was initiated with vigorous fluid resuscitation and intravenous antibiotic therapy. During the next days, the condition of the patient worsened, and pulmonary insufficiency required intubation and mechanical ventilation. Surgical treatment with multiple incision and irrigation was performed on the first, third and eighteenth day. The patient was discharged in good health on the 30th day after admission. Toxic shock syndrome with necrotizing fascitis is a rare disease; therefore, it is important to review its diagnostic and clinical features as only early diagnosis and prompt, radical surgery improves the survival rate.

PURPOSE: Hepatic resection is a standard method of treatment for colorectal liver metastases (CRLM). However, the pathologic factors of metastatic lesions that affect tumor recurrence are less well defined in CRLM. The aim of this study was to evaluate the risk factors for recurrence of CRLM, focusing on histopathologic factors of metastatic lesions of the liver. METHODS: From January 2003 to December 2008, 117 patients underwent curative hepatic resection for CRLM were reviewed. Tumor size and number, differentiation, tumor budding, angio-invasion, dedifferentiation and tumor infiltrating inflammation of metastatic lesions were investigated. RESULTS: The mean number of hepatic tumors was 2 (range, 1-8). The mean size of the largest tumor was 2.9 cm (range, 0.3-18.5 cm) in diameter. The moderate differentiation of the hepatic tumor was the most common in 86.3% of the patients. Tumor budding, angio-invasion, and dedifferentiation were observed in 81%, 34%, and 12.8% of patients. Inflammation infiltrating tumor was detected in 6.8% of patients. Recurrence after hepatic resection appeared in 69 out of 117 cases (58.9%). Recurrence-free survival at 1, 2 and 5 years were 62.4%, 43.6%, and 34.3%. The multivariate analysis showed the number of metastases > or =3 (P = 0.007), the tumor infiltrating inflammation (P = 0.047), and presence of dedifferentiation (P = 0.020) to be independent risk factors for tumor recurrence. CONCLUSION: Histopathological factors, i.e., dedifferentiation and tumor infiltrating inflammation of the metastatic lesion, could be one of the risk factors of aggressive behavior as well as the number of metastases even after curative resection for CRLM.

PURPOSE: Recently, trauma is more frequent due to the increases in the population, the number of traffic accident, and the incidence of violence. Especially, abdominal trauma is a leading cause of morbidity and mortality. We analyzed the clinical features and the factors associated with morbidity and mortality. METHODS: We analyzed 136 patients of abdominal trauma who were admitted at the Department of Surgery, Chonnam National University Hospital, from January 2003 to June 2005. We analyzed the cause of trauma, the injured organ, combined injuries, mental status, blood pressure, laboratory findings, morbidity, and mortality. The relationships between by variable were assesed by using the independent samples test and the Kruskal?Wallis test. RESULTS: The causes of trauma were traffic accidents (98 cases, 72%), falling accidents (9 cases, 6.6%), violence (6 cases, 4.4%), and stab injuries (6 cases, 4.4%). The injured organs were the small intestines (47 cases, 34.6%), the liver (35 cases, 25.7%), the spleen (26 cases, 19.1%), the mesentery (17 cases, 12.5%), the large intestines (15 cases, 11.0%), the pancreas (14 cases, 10.3%), etc. The most common combined injury was chest injury (53 cases, 39%). Comatose or semicomatose mental status and shock on admission (<60 mmHg in systolic) were related to high mortality (85.7%). In laboratory findings, decreased hemoglobin (<8 g/dL), and platelet count (<50,000/mm3), and increased creatinine level (>1.6 mg/dL) were significant prognostic factors. The incidence of postoperative complications was 40.4%, and frequent complications were wound infection (8.1%) and re-bleeding (8.1%). The overall mortality rate was 18.4%, and most common cause was hypovolemic shock (18 cases, 13.2%), however, there was no statistical difference according to injurd organ. CONCLUSION: In the multivariate analysis, mental status, hemoglobin, and serum creatinine level were the most significant prognostic factors. When an abdominal trauma patient arrives at the emergency room, a rapid and accurate evaluation of the patient's status and risk factors, and resuscitation, if necessary, have to be performed to lower the morbidity and mortality.

PURPOSE: One of the most common sites of recurrence after a curative resection of rectal cancer is the pelvis, and local control is a major goal of surgical treatment. The advantages of lateral pelvic lymph node dissection are regarded as questionable because lateral pelvic lymph node metastasis does not occur so frequently and because a lateral lymphadenectomy has a negative influence on the postoperative quality of life. The aim of this study was to clarify if lateral pelvic lymph node dissection (LPLD) conferred any benefit. METHODS: A total of 769 patients who underwent curative surgery for rectal cancer between 1981 and 2005 at the Department of Surgery, OOO Hospital, were reviewed retrospectively. One hundred ninety-three of these patients underwent a lateral pelvic lymph node dissection, and 576 patients had a total mesorectal excision with high ligation of the IMA. RESULTS: There was no difference in pathological characteristics between the two groups. Patients who underwent a lateral pelvic lymph node dissection had no statistically significant difference in terms of the 5-year survival rate at stage II and III (64% vs 65% at stage II, P=0.391; 49% vs 47% at stage III, P=0.815). CONCLUSIONS: A lateral pelvic lymph node dissection has no advantage as part of a standard operation for rectal cancer. A total mesorectal excision alone has good local control and survival compared with a lateral pelvic lymph node dissection.
