Abstract: Objective To compare the advantages,disadvantages and clinical value of the improved loop the jejunum behalf of the stomach surgery and the P - type jejunum on behalf of stomach surgery.Methods 56 patients with gastric cancer were divided into two groups by different ways of gastrectomy alimentary tract after gartrectomy.Patients in observation group( n =35 ) were given the modified loop jejunum on behalf of gastric surgery and patients in control group( n =31 ) received P-type jejunum on behalf of the stomach surgery.The clinical effects were compared between two groups.Results There were no significant differences in surgical time and bleeding volume in 2 groups ( P > 0.05 ).Emptying time [(61 ± 3 ) min] of observation group was longer than that of control group (37 ± 19) min]( t =3.03,P < 0.05 ) ; Each food intake [( 308 ± 44 ) ml] in observation group was significiantly improved compared with control group [(262 ± 34) ml (t =2.55,P < 0.05) ; The times of daily diet [(4.2 ± 1.2) times] in observation group was lower than that of control group [( 5.7 ± 2.3 )] ( t =2.46,P < 0.05 ).The incidence of postoperative complications( 14.3% ) of the observation group was significantly lower than the control group (42.9%) ( x2 =5.71,P < 0.05).Conclusion On the terms of 2 ways of digestive tract reconstruction,the improved loop the jejunum behalf of the stomach surgery is superior to the P-type jejunum on behalf of the stomach surgery,which can effectively improve the quality of life of patients and reduce the incidence of complications,but have no complex surgical procedures.
