Sternoclavicular joint posterior dislocations are considered a very uncommon, and type of injury where if esophagus or airway injury occurs behind the clavicle, it poses a high risk to the patient. In addition, if epiphyseal fracture occurs as a result of the sternoclavicular joint posterior dislocation, surgical treatment is often required. However, in the absence of a complete ossification of the clavicle, it is difficult to differentiate between a simple dislocation and epiphyseal fracture-dislocation solely based on simple radiographs or computed tomography scans. In this case report, the authors present a case in which a sternoclavicular joint posterior dislocation was diagnosed in a 14-year-old male athlete. The case report discusses how the posterior dislocation without epiphyseal fracture was diagnosed using an ultrasound and subsequently treated with successful outcomes using manual reduction. The case report presents our findings along with discussion that includes a literature review of relevant research.

PURPOSE: There has been considerable controversy over the prognosis of gastric signet ring cell carcinoma (SRC). To clarify the biologic behavior of SRC, we evaluated the clinicopathologic features and the prognosis of SRC. METHODS: A total of 3,104 patients with a gastric carcinoma who had undergone a gastrectomy from 1987 to 1995 were analyzed retrospectively. Among them, 556 patients with SRC were compared to 2,548 patients with non-SRC. RESULTS: Patients with SRC were younger than those with non-SRC, and female were prevalent. Incidence of EGC were higher in patients with SRC. EGC with SRC had a larger proportion of mucosa-confined lesions and a lower rate of lymph node metastasis than EGC with non-SRC. Multivariate analysis showed that SRC was a negative inde pendent risk factor for lymph node metastasis. Among advanced gastric cancers SRCs showed a higher prevalence of large-sized lesions, Borrmann type IV lesions, and advanced nodal stage, as well as a higher rate of peritoneal metastasis. The 5-year survival rate of EGC with SRC (93.8%) was higher than that of non-SRC (91.2%). However, the prognosis of advanced SRC (49.0%) was poorer than that of non-SRC (53.5%). CONCLUSION: A female preponderance, a younger age, and a higher proportion of early gastric cancer characterized the peculiar biologic behavior of gastric signet ring cell carcinoma. In addi tion, the prognosis of SRC was poor once invasion had gone beyond the submucosa. These findings suggest that signet ring cell carcinoma of the stomach should be regarded as a distinct type of gastric cancer.

There has been a considerable controversy on the prognosis of the mucinous gastric adenocarcinoma(MGC). In this study we analyzed the clinicopathologic differences between MGC and non-mucinous gastric carcinoma(NMGC). In addition, the relationship between mucin content and other clinicopathologic variables, including prognosis in MGC was examined. We reviewed 2118 patients with pathologically confirmed gastric cancer who had underwent gastrectomy at the department of surgery of Yonsei University College of Medicine, during the period between Jan. 1987 and Dec. 1993. Among them, 130 patients had gastric cancer with extracellular mucin(MGC) and 1988 patients had gastric carcinoma without extracellular mucin(NMGC). We studied the MGC patients into two groups according to mucin content: mucin content involving over 50% of the tumor(dominant type, n=94) and mucin content involving less than 50% of the tumor area(partial type, n=36). The results are as follows: The MGC was more common in male then NMGC. The size of tumor in MGC was larger than that of NMGC. The patients with MGC had higher incidence of Borrmann type IV, more frequent serosal invasion, lymph nodes metastasis and peritoneal metastasis than the patients with NMGC. The patients with MGC had more advanced stage at the time of diagnosis and worse overall 5-year survival rate than the patients with NMGC. But the 5-year survival rate according to the stage of MGC was similar to that of NMGC. There were no significant differences between the mucin content and other pathologic variables including prognosis. So we suggested that MGC has worse prognosis than NMGC and it is reasonable to consider the carcinoma with mucin content involving less than 50% of the tumor area as MGC.

PURPOSE: Even with excellent surgical outcome, recurrence of early gastric cancer (EGC) after a curative resection is not declining because the incidence of EGC is increasing. The aim of this study was to propose an appropriate treatment strategy by assessing the risk factors for recurrence of curatively resected early gastric cancer. MATENRIALS AND METHODS: Of 3662 patients who had undergone gastric resections for gastric cancer from 1987 to 1996, the cases of 1050 curatively resected EGC patients were reviewed retrospectively. Among those 1050 patients, 50 patients (4.8%) were diagnosed as having recurrent cancer, which was confirmed by clinico-radiological examination or re-operation. The risk factors that determined the recurrence patterns were investigated by using univariate and multivariate analyses. RESULTS: The mean time to recurrence was 30.9 months, and hematogenous recurrence was the most frequent type (32.0%). Among the 50 recurred patients, peritoneal recurrence showed the shortest mean time to recurrence (18.5+/-17.7 months). Between the recurred and the non-recurred patients, there was no statistically significant difference with respect to age, sex, operation type, tumor size, tumor location, gross appearance, or histological differentiation. However, depth of invasion (submucosal invasion) and nodal involvement were significantly different (P<0.001) between the two groups. Using logistic regression analyses, nodal involvement was the only significant risk factor for recurrence in early gastric cancer (P<0.001). The median survival after the recurrence had been diagnosed was 4 months. CONCLUSION: Although the prognosis for EGC patients is excellent and recurrence of EGC after a curative resection is rare, the time to recurrence and the patterns of recurrence in EGC patients were diverse and unpredictable, and the result after recurrence is dismal. Considering the impact of lymph node metastasis on recurrence of EGC, a systematic lymphadenectomy, rather than limited surgery, should be performed if lymph node involvement is confirmed pre- or intraoperatively. Also if the postoperative pathologic findings reveal lymph node involvement, adjuvant chemotherapy is recommended.

Endometriosis is defined as the presence of endometrial tissue outside the uterus and located usually within the pelvis. It may be detected as a rare complication associated with surgery. Endometriosis following obstetric and gynecologic procedure, which is localized mostly in the surgical scar including Cesarean section scar, hysterotomy scar, trocar scar, Bartholin cyst exision scar, or episiotomy scar, may caused by implantation of endometrial gland and stroma. Endometriosis developing after hysterectomy, especially, is a quite rare condition except a recurrent disease. We have experienced a case of a 47-year-old woman who had diagnosed ovarian endometriosis two years after laparoscopically assisted vaginal hysterectomy for a large leiomyomatous uterus with no evidence of endometriosis, so we report this case with a brief review of literature.

The incidence of heterotopic gastric mucosa located in the submucosa in resected stomach specimens has been reported to be 3.0 to 20.1%. Heterotopic gastric mucosa is thought to be a benign disease, which rarely becomes malignant. Heterotopic gastric mucosa exists in the gastric submucosa, and gastric cancer rarely occurs in heterotopic gastric mucosa. Since tumors are located in the normal submucosa, they appear as submucosal tumors during endoscopy, and are diagnosed through endoscopic biopsies with some difficulty. For such reasons, heterotopic gastric mucosa is mistaken as gastric submucosal tumor. Recently, two cases of early gastric cancer arising from heterotopic gastric mucosa in the gastric submucosa were treated. Both cases were diagnosed as submucosal tumors based on upper gastrointestinal endoscopy, endoscopic ultrasound, and computed tomography findings, and in both cases, laparoscopic wedge resections were performed, the surgical findings of which also suggested submucosal tumors. However, pathologic assessment of the surgical specimens led to the diagnosis of well-differentiated intramucosal adenocarcinoma arising from heterotopic gastric mucosa in the gastric submucosa.

PURPOSE: This study was done to evaluate the usefulness of preoperative computed tomography (CT) and intraoperative laparoscopic ultrasound to facilitate treatment of gastric submucosal tumors. MATERIALS AND METHODS: The feasibility of laparoscopic wedge resection as determined by CT findings of tumor size, location, and growth pattern was correlated with surgical findings in 89 consecutive operations. The role of laparoscopic ultrasound for tumor localization was analyzed. RESULTS: Twenty-three patients were considered unsuitable for laparoscopic wedge resection because of large tumor size (N=13) or involvement of the gastroesophageal junction (N=9) or pyloric channel (N=1). Laparoscopic wedge resection was not attempted in 11 of these patients because of large tumor size. Laparoscopic wedge resection was successfully performed in 65 of 66 (98.5%) patients considered suitable for this procedure. Incorrect interpretation of preoperative CT resulted in a change of surgery type in seven patients (7.9%): incorrect CT diagnosis on gastroesophageal junction involvement (N=6) and on growth pattern (N=1). In 18 patients without an exophytic growth pattern, laparoscopic ultrasound was necessary and successfully localized all lesions. CONCLUSIONS: Preoperative CT and laparoscopic ultrasound are useful for surgical planning and tumor localization in laparoscopic wedge resection.

The incidence of ectopic pregnancy has been increasing for many years and ectopic pregnancy is still a leading cause of maternal death although its mortality is reduced significantly with improved early diagnosis and treatment. Intraligamentous pregnancy, a subset of ectopic pregnancy, is one of the most unusual accident so that the diagnosis of intraligamentous pregnancy is hardly ever made prior to laparotomy. We experienced intraligamentous pregnancy with hemoperitoneum. So we presented a case with brief review of literature.
