Does laparoscopy decrease anastomotic leak rate in sigmoid colectomy for diverticulitis?
Anastomotic leaks occurred less frequently after laparoscopic sigmoid colectomy performed by experienced laparoscopic colorectal surgeons.
Residual stenoses after extraction atherectomy, rotational atherectomy and excimer laser angioplasty were more severe than after balloon angioplasty but were due to undersized devices (low D/A ratio), not to inefficient devices (low RLD/D ratio). Rotational atherectomy and excimer laser angioplasty were more efficient (higher RLD/D) than balloon angioplasty, whereas extraction atherectomy and balloon angioplasty were similar.
