Interlocking box jejunostomy: A new technique for enteral feeding

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.
