Like any surgical procedure, a gastrojejunostomy could result in infection or another complication. A gastrojejunostomy connects the stomach to the jejunum, bypassing the duodenum, the beginning of the intestine at the bottom of this image.
One more thing: Don't make your turtle's water temperature too warm. For most adult aquatic turtle species, 78 F. (25.5 C.) is the highest you want unless you're treating them for an illness and a veterinarian has told you to raise the temperature. Otherwise, too-warm water can encourage bacteria growth in the tank. It also discourages turtles from basking sometimes.
Eastern Box Turtles like to soak often and should have an adequately large water dish that they can easily get in and out of. When kept indoors I usually soak them once a week in a large dishpan with a couple inches of lukewarm water. They tend to defecate in the water dish so these need to be cleaned daily. Humidity is a major issue. Most box turtles are kept far to dry. This leads to eye problems which are often mistaken for eye infections and/or respiratory infections. To keep the humidity high I use sphagnum moss/Bed-a-Beast/sand mix. This is kept moist with daily misting. They should have hiding spots and an area for burrowing available. Eastern Box Turtles should have a basking area that is maintained at 87-90Â°F., and a cooler, shaded area. Diet: 60% or more of the diet is composed of animal matter.
