Melanoma is a malignant neoplasm of melanocytes most frequently arising from the skin, but primary melanoma can also arise from the mucosa of the gastrointestinal tract. Gastrointestinal melanomas are most commonly metastases from a cutaneous melanoma. Primary melanoma of the stomach is rare and carries a poor prognosis. Reported here is the case of a 75-year-old man with a primary gastric melanoma who presented with a melena, abdominal pain, and weight loss. Most cases of melanoma are treated by excision of the primary tumor. Patients with melanoma have been treated with adjuvant chemotherapy, radiation therapy, and immunotherapy. None of these modalities has been demonstrated to prolong the survival rate. To improve long-term disease-free survival, early diagnosis and surgical intervention are very important.

A benign cecal ulcer is an uncommon lesion. The etiology remains unknown, and there are no pathognomonic lesions or symptoms. Lower gastrointestinal tract hemorrhage secondary to benign cecal ulcer is the most common complication. Herein, the case of a 24-year-old man with a benign cecal ulcer presenting with a massive lower gastrointestinal tract hemorrhage requiring transfusion until a exploratory laparotomy and right hemicolectomy, is reported with a review of the literature. Surgical intervention is warranted if malignancy is suspected or if the patient has signs of uncontrollable hemorrhage, perforation, or peritonitis.

PURPOSE: The number of resected lymph nodes can influence the current N staging. This study examined the significance of the metastatic lymph node ratio on the survival of patients with pT2 gastric cancer. METHODS: The records of 176 patients who had undergone curative gastrectomy and diagnosed with pT2 gastric cancer by pathology, between February 1990 and October 2002 were retrospectively reviewed. Those patients with other organ metastases or those who had undergone a dissection of less than 15 lymph nodes were excluded. The clinicopathologic prognostic variables were evaluated using the SPSS statistical program. RESULTS: There were 115 men and 61 women with a mean age of 59 years. The median survival period was 93 months (2~184 months). Metastatic lymph nodes were found in 100 cases (56.8%), a mean of 34.6 lymph nodes were dissected, a mean of 3.2 lymph nodes metastasized, and a mean metastatic lymph node ratio of 0.09 was found. According to the UICC TNM classification, the number of stage IB (N0) cases was 76 (43.2%), stage II (N1) was 74 (42.0%), stage IIIA (N2) was 18 (10.2%), and stage IV (N3) was 8 (4.5%). The overall 5-year survival rate was 75.2%. According to the UICC TNM classification, the 5-year survival rate was stage IB, II, IIIA, and IV was 88.6%, 74.3%, 39.5%, and 33.3%, respectively. The metastatic lymph node ratio (nR) was divided into 4 categories; nR0 (76) = 0, 0 Classification ; Female ; Gastrectomy ; Humans ; Lymph Nodes* ; Male ; Neoplasm Metastasis ; Pathology ; Prognosis ; Retrospective Studies ; Stomach Neoplasms* ; Survival Rate*

We had experienced 2 cases of acute phlegmonous gastritis confirmed by endoscopy, microbiological study and surgical pathologic findings. The first was a 61- year-old female who had been diagnosed as the communicating hydrocephalus and the other was a healthy 60-year-old female. Enterococcus fecalis & Klebsiella pneumoniae, Enterococcus fecalis & E.coli were cultured from the gastric tissue and juice obtained by endoscopy in each patient. In both patients, endoscopic findings showed numerous large ulcers and edema with necrotic material and exudate over the whole stomach. Operation findings were markedly edematous and overall ulcerative mucosa in one patient, and hyperemic outlet stricture in the other. Pathologic findings were acute necrotizing inflammation, involving the mucosa and submucosal layer, consistent with acute phlegmonous gastritis. After operation and antibiotics therapy, the patients were rapidly improved. We reported 2 cases of acute phlegmonous gastritis with the review of literature.

PURPOSE: Laparoscopic cholecystectomy (LC) has replaced open cholecystectomy (OC) for the treatment of gallbladder disease. However certain cases still require conversion to open procedures. Identifying these patients at the risk of conversion remains difficult. This study evaluated risk factors that may predict conversion from a laparoscopic to an open procedure. METHODS: From January 1994 to December 2004, a total of 582 laparoscopic cholecystectomies were performed at Seoul Medical Center. A retrospective analyses of clinical parameters including patient demographics, clinical histories, laboratory data, ultrasound results, intraoperative details and postoperative pathologic findings were performed. RESULTS: A total of 30 patients (5.2%) had their cholecystectomies converted to an open procedure. Causes for conversion were inability to correctly identify the anatomy of surgical field due to adhesion and inflammation (56.7%), bile duct injury (13.3%), bleeding (13.3%) and others (16.7%). Univariate analysis showed that ASA (the classification of American Society of Anesthesiologists, p = 0.034), previous abdominal operation history (p = 0.008), RUQ tenderness(right upper quadrant tenderness, p = 0.002), acute cholecystitis (p < 0.001) and time elapsing between diagnosis and operation (p = 0.013) to be risk factors. Multivariate analysis revealed that acute cholecystitis (4.2 greater odds ratio [OR] of conversion, p = 0.002) and previous abdominal operation history (3.6 greater odds ratio [OR] of conversion, p = 0.003) were positive independent predictive factors for conversion to open cholecystectomy. CONCLUSION: Although laparoscopic cholecystectomy is a safe and beneficial procedure in the management of patients with gallbladder disease, there are still many chances of conversion of laparoscopic to open cholecystectomy. In this study, patients with acute cholecystitis and previous abdominal operation histories were more likely to require conversion to an open procedure. These two positive independent predictive factors can help operators to make early decision and to counsel patients undergoing laparoscopic cholecystectomy with regards to the posibility of conversion to an open procedure.

The frequencies of multiple synchronous carcinomas of the colon and the rectum have been reported to range from 2.1 to 6.3%. Currently, the frequency is higher in colorectal cancer patients, and the diagnosis is better due to the many diagnostic tools that have been developed. There are a few reported cases of five cancers in a patient at the same time. We report here on the case of five synchronous cancers arising from the colon and the rectum in a patient without a familial history of colon cancer or of genetic predisposing factor. The patient was a 62-yr-old woman who presented with frequently loose stool for six months and intermittent abdominal pain for two months. Colonoscopic examination revealed two adenocarcinomas, one each at the sigmoid colon and the rectum; the cancer in the sigmoid colon was obstructed at nearly 40 cm above the anal verge. Computed tomographic colonoscopy revealed many other polyps and masses in the colon and a metastatic mass at segment 8 in the liver. A total proctocolectomy and ileostomy were performed. Histologic evaluation revealed the five lesions to be adenocarcinomas invading the pericolic fat; 1 out of 30 lymph nodes was invaded by the cancer cells.

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.

OBJECTIVE: This study was performed to describe the clinical presentation, surgical outcome in patients with symptomatic myelopathy caused by ossification of the yellow ligament (OYL). METHODS: The authors reviewed consequent 12 patients in whom posterior decompressive laminectomies were performed for OYL from 1999 to 2005. Diagnostic imagings including simple radiographs, computed tomography and magnetic resonance images were performed in each case. The patients were reviewed to evaluate the clinical presentation, surgical outcome and complications of the operation. RESULTS: In all patients, OYL was located in the lower thoracic region and all patients presented with numbness on both limbs and pain. Among them, 5 patients presented with gait disturbance due to paraparesis and two patients had sphincter dysfunction. Decompressive laminectomy through a posterior approach using microscope resulted in improvement of symptoms in all patients, but, recovery was incomplete in a half of the patients. The mean postoperative Japanese orthopaedics association (JOA) score was 7.9 when compared with 4.9 in preoperative assessment and the mean recovery rate was 65%. Dural tear was noticed in four patients, so dural repair was performed, but there were no neurological deficits related to neural injury. CONCLUSION: OYL is an uncommon cause of myelopathy but it can lead to debilitating thoracic myelopathy. Careful decompressive laminectomy can achieve favorable results.

PURPOSE: Fitz-Hugh-Curtis (FHC) syndrome has been described as perihepatitis associated with pelvic inflammatory disease during surgery. Recently, on computerized tomography a linear enhancement of the liver capsule was detected in a patient with FHC syndrome. We studied to evaluate the clinical course of the disease. METHODS: Sixteen patients diagnosed with FHC syndrome from CT findings were retrospectively studied from April, 2006 to June, 2008. RESULTS: The mean age of the patients was 25.9 (19~35) years and mean duration of abdominal pain was 3.9 (1~14) days. The most common complaint was right upper quadrant area pain (11 cases, 68.8%). 12 patients showed leukocytosis and all the patients had elevated serum C-reative protein levels. All the patients had normal liver function. Among the 9 patients which had polymerase chain reaction test for sexually transmitted disease (Chlamydia trachomatis, Ureaplasma urealyticum, Neisseria gonorrheae, Mycoplasma hominis), all showed more than one positive results (Chlamydia trachomatis 6 cases, Ureaplasma urealyticum 6 cases, Mycoplasma hominis 2 cases). On simple abdomen X-ray, 7 cases (43.8%) showed paralytic ileus. 14 cases received only antibiotic treatment, but 1 case had to take operation (laparoscopic-assisted adhesiolysis) due to constant abdominal pain and prolonged ileus. CONCLUSION: It is important to rule out FHC syndrome by using CT findings, especially young women with right upper abdominal pain and PID. Usually, FHC syndrome can be treated easily with proper antibiotics.

PURPOSE: In Korea, the entire population must enroll in the national health insurance system, and those who are classified as having a lower socioeconomic status are supported by the medical aid system. The aim of this study was to evaluate the association of the medical insurance status of gastric cancer patients with their survival after gastrectomy. MATERIALS AND METHODS: A total of 247 patients who underwent surgical treatment for gastric cancer between January 1999 and December 2010 at the Seoul Medical Center were evaluated. Based on their medical insurance status, the patients were classified into two groups: the national health insurance registered group (n=183), and the medical aid covered group (n=64). The survival rates were calculated using the Kaplan-Meier method. RESULTS: The median postoperative duration of hospitalization was longer in the medical aid covered group and postoperative morbidity and mortality were higher in the medical aid group than in the national health insurance registered group (P<0.05). The overall 5-year survival rate was 43.9% in the medical aid covered group and 64.3% in the national health insurance registered group (P=0.001). CONCLUSIONS: The medical insurance status reflects the socioeconomic status of a patient and can influence the overall survival of gastric cancer patients. A more sophisticated analysis of the difference in the survival time between gastric cancer patients based on their socioeconomic status is necessary.
