A tip section of a multi-camera endoscope includes a front-pointing camera on a planar surface of a distal end of the tip section and two side-pointing cameras positioned in depressions on a cylindrical surface in proximity to the planar surface such that the side field of view provided by the two side-pointing cameras partially overlaps with the front field of view provided by the front-pointing camera. The tip section further includes a working channel configured for insertion of a surgical tool and a pathway fluid injector for inflating and/or cleaning a body cavity into which the endoscope is inserted.
