[Rationale and selection for combined procedures in colonic dysplasias and T1 carcinomas. Laparoscopic-endoscopic local wall excision and segment resection].

Combined endoscopic-laparoscopic procedures may offer an interesting therapeutic option in cases of benign colonic lesions and early T 1 carcinoma where endoluminal resection is not feasible, but oncological resection is not (yet) required. Combined procedures such as the laparoscopically assisted endoscopic resection, the endoscopically assisted laparoscopic wedge or transluminal resection, or the segmental resection can be performed. Experience with this technique is still limited, but has shown that the invasiveness can be reduced by endoscopically guided local excision. If it is possible to keep the incidence of secondary operations low, combined laparoscopic/endoscopic interventions could occupy a valuable place in the therapeutic spectrum.
