Ca colon was detected during colostomy surgery because of obstruction in intestines was done on 28/09/2020 and water confirmed by biopsy at sri balaji action medical institute, paschim vihar, new delhi 110063. Close/reversal stone surgery was also advised after successful 6 chemotherapy sessions. Second opinion was taken at all india institute of medical sciences, new delhi (dr. B. R ambedkar irch ). After investigations, ca colon was confirmed and chemotherapy was started at aiims. Total 4 chemotherapy sessions were performed. Last chemotherapy session, was done on 21/01/2021 at aiims. Later because of accidental fall and one month period was needed for surgery after chemotherapy, treatment was disrupted. Bipolar hemi artho plastic surgery was performed on 24/02/2021 at aiims. Currently under treatment at day care chemotherapy center and follow up at irch, aiims. Current pet scan indicated" no significant metabolically active disease noted at present. Possible recurrence may happen has been advised on follow up visit. Consultations are being carried out by team of doctors at aiims for further treatment/advise. My query at present is that now since chemotherapy is over, can close/reversal surgery can be performed. Second query is whether surgery is immediately advised now or preferably can wait, if possible, because I am not able to independently sit or stand on my own. Chemotherapy sessions are on. I feel colostomy bags are convenient at this time rather than sitting on commode seat and would like to wait for close/reversal surgery. What is advisable period of gap between initial colostomy surgery and close/reversal surgery? Please advise?
