A gastrointestinal stromal tumor (GIST) is a type of tumor that occurs in the gastrointestinal tract, most commonly in the stomach or small intestine. The treatment for primary GIST is surgical resection whenever possible. The goal of the surgeon is to remove the entire tumor without rupturing it.
After endoscopic diagnosis of rectal cancer with biopsies, pre-operative work-up consists of thoraco-abdominal CT-scan to assess local or distant metastatic lesions. Assessment of local tumour spread is performed by anal endo-rectal ultrasound and/or pelvic magnetic resonance imaging (MRI). In cases of advanced rectal cancer, radio-chemotherapy is advised before surgical resection. Laparoscopic robotic surgical resection of the rectum with total mesorectal resection (TME), creation of a colonic J-pouch with temporary protective ileostomy is then advised.
