They found piles which they are going to band but haven't properly looked into the bowel because of the discomfort. Confirm that the patient performed the recommended enemas and bowel preparation. If a suspected cancer is encountered (an irregular, obstructing, friable or bleeding mass), it may be sampled for biopsy, but vigorous bleeding of the lesion may ensue. Polyps less than 5 mm in diameter should be biopsied. 7. Special insertion techniques, such as torquing (twisting the scope in the right hand), dithering (rapid, short back-and-forth motions to advance the scope), accordionization (pulling back on angled portions of colon wall with the scope tip, allowing the scope tip then to advance with the colon folded—like an accordion— onto the scope) and hooking and straightening (Figure 1) may be required to negotiate the many turns in the sigmoid.
