“…Generally, at the begining of disease catheter drainage of infected necrotic tissue is poor and several authors consider that surgical resection of necrotic tissue is mandatory [3,4,[7][8][9][25][26][27]. But, some authors deem [12][13][14][15][16][17][18][19] that solid tissue and necrotic debris could be removed with draining fluid and that the use of vigorous irrigation through large-bore catheters could effectively remove the tissue. The rationale for this strategy is that large bore catheters may be more effective for mobilizing solid tissue and evacuating the necrotic tissue from the cavities.…”
