if any git tumor present in around caecum ,why we do colectomy till half the transverse colon not done around the affected tumor ?
The marginal artery formed on the right side are from the branches of SMA and separately cannot be dissected during surgery so we will have to dissect as a whole the part supplied by the SMA upto the right branch of MCA (jejunum and most of the ileum can be saved as they are supplied by branches mostly arising from the left side of SMA)… Sir kindly correct me if I am wrong
Meet Patel In body the marginal artery lies in mesentery so all the branches cannot be ligated individually… And as they can’t be ligated there will be high risk of loco-regional recurrence from the RCA and MCA territories if only cecal mass is resected
Along with the tumour we need to excise the lymph nodes also for R0 resection to prevent locoregional recurrence, so we need to excise the entire right colon until it’s watershed area that’s is upto 2/3rd transverse colon.
If we remove only ceacum then the risk of node positive increases.
If it’s a tubercular mass (benign) for example in ceacum then only cecal excision can be done.
