Ligation of cord in orchidectomy for treatment of testicular tumor is done at –
**Core Concept**
Ligation of the cord in orchidectomy is crucial to prevent tumor dissemination through the lymphatic channels. This procedure involves the surgical removal of the testis, along with the surrounding structures, including the spermatic cord.
**Why the Correct Answer is Right**
The spermatic cord contains lymphatic vessels that can facilitate the spread of testicular cancer cells. By ligating the cord, the surgeon aims to prevent the tumor cells from entering the lymphatic system, thereby reducing the risk of metastasis. This procedure is particularly important in the context of testicular tumors, as they have a high propensity for lymphatic dissemination.
**Why Each Wrong Option is Incorrect**
**Option A:** This is incorrect because ligation of the cord is not typically performed for testicular injuries or benign conditions, where the primary concern is not tumor dissemination.
**Option B:** This is incorrect because ligation of the cord is not a standard procedure in varicocele repair or other conditions affecting the spermatic cord.
**Option C:** This is incorrect because ligation of the cord is not a necessary step in vasectomy procedures, where the primary goal is to interrupt sperm transport.
**Clinical Pearl / High-Yield Fact**
During an orchidectomy for testicular tumor, it is essential to identify and ligate the spermatic cord to prevent lymphatic spread of cancer cells. This highlights the importance of meticulous surgical technique in oncological procedures.
