Occasionally,patients with this condition are diagnosed with malignant tumors. We report a case of a 60-yearold woman with gastric cancer and SIT. Laparoscopyassisted distal gastrectomy(LADG) with D2 lymph node dissection and Billroth Ⅱ anastomosis were performed successfully on the patient by careful consideration of the mirror-image anatomy. The operation required 230 min, and no intraoperative complications occurred. The final pathological report was p T4 a N0M0,according to the American Joint Committee on Cancer 7th edition staging guidelines. The postoperative course was favorable, and the patient was discharged on postoperative day 8. We believe that this is the first case of LADG with D2 lymphadenectomy reported in a SIT patient with advanced gastric cancer.展开更多

Situs inversus totalis(SIT) is a rare anomaly in which the abdominal and thoracic cavity structures are opposite their usual positions.Occasionally,a few patients with a combination of this condition and malignant tumors have been encountered.Recently,several laparoscopic operations have been reported in patients with SIT.We report a case of an 83-year-old man with situs inversus totalis who developed colon cancer after open distal gastrectomy.Laparoscopic hemicolectomy with radical lymphadenectomy in such a patient was successfully performed by careful consideration of the mirror-image anatomy.Techniques themselves was not different from those in ordinary cases.Thus,curative laparoscopic surgery for colon cancer in the presence of situs inversus totalis is feasible and safe.展开更多

A woman presented with cyanosis, clubbing of fingers and distal edema. Chest examination revealed heart sounds at the right side and a heart murmur. Abdominal examination showed liver dullness in the left side. The X-rays showed dextrocardia and liver in the left side. The Upper digestive barium test showed the stomach in the right side, the barium enema showed caecum on the left. Treatment for heart failure improved the patient’s condition and she remained well. When she became pregnant, developed heart failure again and required admission. She was compensated and continued her pregnancy. 3 years later she developed heart and respiratory refractory failure, was admitted again and after few days she died. We report this case of situs inversus totalis in association with hypertrophic osteoarthropathy because of the rarity of this anomaly.展开更多
