In Japan, many surgens still continue to place a information and prophylactic drainage tube after colectomy. However, some randomized controlled trials have already reported that a prophylactic drainage is unnecessary after colectomy.
The aim of this study is to determine the necessity of prophylactic drainage after laparoscopic colectomy retrospectively.
[Methods and Procedures]
Between April 2007 and August 2011, 272 patients who underwent laparoscopic ileocolic resection, right hemicolectomy, and sigmoidectomy were included in this study.
Until February 2011, a prophylactic closed suction drainage tube was inserted in all cases. After March 2011, no drainage was performed after coloectomy in principle. Intraoperative factors and short term results were compared between 240 drainage group and 32 no drainage group.
Mean operative time of no drainage group was 155min and shorter than that of drainage group (179min) (p=0.007). No statistically significant difference was revealed in postoperative hospital stay (7.5 vs 8.8days). Anastomotic leakage occurred in only one case of drainage group. There were no complications associated with drainage tube like retrograde infection, pressure necrosis by drainage tube, and incisional hernia.
Any significant benefit of routine prophylactic drainage after colectomy did not observed. Therefore it is not necessary for laparoscopic colectmy to place drainage tube.
