Intervention group (decompressing stoma as bridge-to-surgery arm)
stoma
In the intervention group, patients will undergo a two-stage resection with a decompressing stoma procedure. After a period of convalescence, an elective, oncologic left hemicolectomy will be performed. The stoma technique during the first procedure can be performed as either loop or blowhole colostomy (a loop ileostomy is also possible if deemed adequate), while the elective resection can be conducted as a primary anastomosis with or without loop ileostomy or a Hartmann’s procedure. The time interval between the decompressing stoma and resection will be determined by the treating surgeon, with an expected period of approximately 30 days based on current studies [Any additional concurrent care, including the use of adjuvant therapy after resection, is left to the discretion of the treating physicians.
