Background. Long-gap esoph­a­geal atre­sia con­tin­ues to be a chal­leng­ing pedi­at­ric tho­rac­ic sur­gi­cal prob­lem. Despite the use of var­i­ous ten­sion reliev­ing pro­ce­dures, the esoph­a­geal anas­tom­o­sis is ­often per­formed ­under con­sid­er­able ten­sion. Excessive ten­sion can ­cause anas­to­mot­ic ­sutures to ­pull ­through the esoph­a­geal tis­sue, ­with resul­tant ear­ly esoph­a­geal anas­to­mot­ic dehis­cence. To ­test the hypoth­e­sis ­that inter­rupt­ed hor­i­zon­tal mat­tress ­sutures ­would with­stand the forc­es of ten­sion bet­ter ­than inter­rupt­ed sim­ple ­sutures, an experi­men­tal ­study of rat esoph­a­geal anas­to­mos­es was ­done.
Methods. Twenty ­rats ­were ­killed and ­their esoph­a­gi ­were ­excised. The esoph­a­gi ­were divid­ed in the mid por­tion and end-to-end anas­to­mos­es ­were ­done ­using inter­rupt­ed 6-0 poly­pro­py­lene ­sutures. Ten ­rats had anas­to­mos­es ­done ­with inter­rupt­ed sim­ple ­sutures and ten had inter­rupt­ed hor­i­zon­tal mat­tress sutur­ing. Anastomotic break­ing ­strength was test­ed in a ten­sio­me­ter.
Results. Anastomotic break­ing ­strength was 3.22±0.56 N for the inter­rupt­ed sim­ple ­sutured anas­to­mos­es and 3.51±0.61 N for the inter­rupt­ed hor­i­zon­tal mat­tress ­group (p=0.30). The dif­fer­ence was not sig­nif­i­cant.
Conclusions. In ­this ani­mal ­study inter­rupt­ed sim­ple and hor­i­zon­tal mat­tress sutur­ing with­stood the dis­rup­tive forc­es of anas­to­mot­ic ten­sion equal­ly ­well.
