Diagnosis, treatment and literature review of situs inversus totalis combined with intestinal neoplasms

摘要

Objective To investigate the diagnosis and treatment of situs inversus totalis (SIT) combined with intestinal neoplasms. Methods The clinical manifestations, diagnosis, and treatment of 1 patient with thoracic-abdominal visceral complete transposition and colorectal cancer was analyzed, and the literatures retrieved from 2007 to 2017 were reviewed. Results The clinical manifestations of the patient were abdominal distension and anemia.The chest and abdomen CT showed: the cardiac apex pointing forward to the right, the thoracic-abdominal tissues and organs completely reversed.Tumor was on the left side and was diagnosed as cecum and ascending colon cancer.Gastroscope showed gastric translocation.The patient underwent radical resection of colon cancer under general anesthesia, postoperative pathology showed colonic adenocar-cinoma. Conclusions Due to abdominal organ transposition, SIT patients often present opposite symptoms so that misdiagnosis is frequent.It should be as much as possible to complete all relevant tests to confirm the diagnosis and guide operation of the surgery.Diagnosis and treatment should follow the reverse thinking principle.In addition, SIT patients combined with digestive tract tumors are not contraindications for laparoscopic and robot surgery, the operation result is also safe and effective.
