Application of intracavity double pipe suction in the repair of duodenal rupture

Objective To investigate the effects of intracavity double pipe suction in the duodenal rupture repair.Methods The clinical data of 56 patients with duodenal rupture repair who were admitted to Fuzhou General Hospital from January 2003 to January 2014 were retrospectively analyzed.Thirty-one patients and 25 patients received the simple drainage (simple drainage group) and intracavity double pipe suction (intracavity double pipe suction group) for duodenal rupture repair.Quantitative data were presented by $ ± s,repeated measures analysis of variance and the t-test were used to evaluate quantitative data,respectively.Count data were analyzed using Chi-square test or Fisher's exact test.Results Volume of drainage of patients in the intracavity double pipe suction group at day 1,2,3,4,5,6,7 were (220 ± 54) mL,(284 ± 65) mL,(368 ± 35) mL,(413 ± 41) mL,(454 ± 62) mL,(714 ± 96) mL and (852 ± 121) mL,compared with (102 ± 30) mL,(124 ± 29)mL,(186 ±26)mL,(110 ±21)mL,(167 ±31)mL,(193 ±35)mL and (182 ±44)mL in the simple drainage group,with a significant difference between the 2 groups (F =65.214,P ＜ 0.05).The volumes of drainage of the 2 patterns were compared at postoperative day 1 to 7,with a significant difference (t =9.532,11.624,13.421,15.257,14.147,18.311,20.135,P ＜0.05).The incidence of duodenal fistula,intraperitoneal infection and wound infection in the simple drainage group were 29.0％ (9/31),41.9％ (13/31) and 51.6％ (16/31),compared with 4.0％ (1/25),12.0％ (3/25) and 16.0％ (4/25) in the intracavity double pipe suction group,showing a significant difference between the 2 groups (x2 =4.460,6.077,7.645,P ＜ 0.05).The incidence of pancreatic fistula and pulmonary infection in the sample drainage group and intracavity double pipe suction group were 16.1％ (5/31) and 29.0％ (9/31),8.0％ (2/25) and 12.0％ (3/25),with no significant difference between the 2 groups (x2 =0.836,2.385,P ＞ 0.05).The duration of hospital stay and hospital expenses in the simple drainage group and the intracavity double pipe suction group were (30 ± 14) days and(12 ± 6) x 104 yuan,(21 ± 7) days and (7 ± 5) x 104 yuan,respectively,with significant difference between the 2 groups (t =3.161,2.913,P ＜ 0.05).Conclusion The intracavity double pipe suction for duodenal rupture repair is simple and effective for significantly improving the prognosis of patients and reducing the duration of hospital stay and hospital expenses.
