Abstract:Background. This retrospective study was carried out to review our surgical experience and to define the clinicopathologic profile of early gastric cancer in a Western country with one of the highest incidences in the world. Methods. Fifty-eight patients who had gastric surgery for early gastric cancer were included in this study. Results. The incidence of early gastric cancer was 13.9% of the patients with resected gastric cancer (58/416). The mean age of these 58 patients at diagnosis was 56.8 ؎ 12.3 years (range, 30-81 years) and the male : female ratio was 2.4 : 1. The most common presenting symptom was epigastric pain (52.4%). All patients were treated by surgical resection. Tumors were typically located in the antrum (72.4%), with a predominance of lesser curvature lesions (89.7%). Macroscopically, the majority of the lesions (63.8%) were excavated (types IIc and III). Thirty tumors were intramucosal and 28 extended into the submucosa. Thirty were of the intestinal type and 28 of the diffuse type. The rate of regional lymph node metastasis was 10.4%. The overall 5-year survival rate was 93.9%. Conclusions. The excellent response to surgical resection of early gastric cancer reported by Japanese authors is reproducible in Western countries even in the presence of regional lymph node metastasis. For this reason an aggressive surgical approach should be taken for all early gastric cancer.
SUMMARYAppendicular intussusception is an uncommon entity, with a reported incidence of 0.01%. The diagnosis is difficult and often only performed at the time of surgery. Intussusception has multiple causes including tumours, foreign bodies and polyps. The definitive treatment is surgical, and the extent of resection is determined by the underlying pathology and degree of invagination. Endometriosis is a rare cause of appendicular intussusception, with 194 cases described in the English literature. We report a case of a 42-year-old woman who presented with chronic abdominal pain in the lower right quadrant. A mass at the caecum was identified during investigations for renal stones by CT. Colonoscopy showed a polypoid lesion, with presumed origin in the appendix. Ileocaecal resection was performed because an appendicular tumour was suspected. Pathological examination identified endometriosis of the appendix and associated peritoneum with invagination of the caecum. The patient was discharged 7 days after surgery and is currently asymptomatic. BACKGROUND
