A new jejunostomy tube placement technique is described and compared to tra
ditional methods. The interlocking box technique was compared to a simple p
urse-string with jejunopexy and an inverting serosal tunnel (Witzel techniq
ue) with jejunopexy. Procedures performed in fresh canine cadavers were flu
id pressure tested following tube removal. Mean +/- standard deviation (SD)
intraluminal pressure necessary to induce leakage at the jejunopexy site o
f the interlocking box group (87.63 +/- 40.56 cm H2O) was significantly gre
ater (p less than 0.001) than the simple purse-string (43.17 +/- 31.69 cm H
2O) and serosal tunnel (46.33 +/- 23.60 cm H2O) groups. Significant differe
nces were not identified between the latter groups. The interlocking box te
chnique resisted leakage following acute removal better than conventional t
echniques and should be tested clinically.
