摘要
Iatrogenic tumor implantation is a condition that results from various medical procedures used during diagnosis or treatment of a malignancy.It involves desquamation and dissemination of tumor cells that develop into a local recurrence or distant metastasis from the tumor under treatment.The main clinical feature of the condition is nodules at the operation's porous channel or incision,which is easily diagnosed in accordance with the case history.Final diagnosis can be made based on pathological examination.Tumor implantation may occur in various puncturing porous channels,including a laparoscopic port,abdominal wall incision,and perineal incision,etc.Besides a malignant tumor, implantation potential exists with diseases,such as a borderline tumor and endometriosis etc.Once a tumor implantation is diagnosed,or suspected,surgical resection is usually conducted. During the diagnosis and treatment of diseases,avoiding and reducing iatrogenic implantation and dissemination has been regarded as an important principle for surgical treatment of tumors.In a clinical practice setting,if possible,excisional biopsy should be employed,if a biopsy is needed.Repeated puncturing should be avoided during a paracentesis.In a laparoscopic procedure,the tissue is first put into a sample bag and then is taken out from the point of incision.After a laparoscopic procedure,the peritoneum,abdominal muscular fasciae,and skin should be carefully closed,and/or the punctured porous channel be excised.In addition,the sample/tissue should be rinsed with distilled water before surgical closure of the abdominal cavity, allowing the exfoliated tumor cells to swell and rupture in the hypo-osmolar solution.Then surgical closure can be conducted following a change of gloves and equipment.The extent of hysteromyomectomy should as far as possible be away from the uterine cavity.The purpose of this study is to make clinicians aware of the possibility of tumor implantation and to give special attention to avoid,or reduce iatrogenic implantation during a surgical procedure.
