Patients Review
Case Study
The cancer was at two places in colon and multiple polyps throughout the colon which also could convert into cancer. The only option was undergoing surgery.
Considering the patient’s age the relatives were in doubt whether to go ahead with such a major surgery. After understanding about the laparoscopic approach in which the surgery is done through small holes and a very small cut is taken to remove the colon, patients family decided to take the risk.
Total Laparoscopic Colectomy was done and the patient recovered very smoothly without any postoperative complications. She is now living a normal life with her relatives with no diet restrictions.
Laparoscopic or Robotic approach for Colorectal Cancers have many advantages like no big cut meaning less postop pain, faster and smooth recovery, hardly any scar and least complications.
