A recent review (RJ Sealock, K Munot. Clin Gastroenterol Hepatol 2018; 16: 1864-69) provides a quick review of some common and rare problems: infection, buried bumper, leakage, bleeding, colonic perforation, tube dislodgment, and nonhealing stoma.
It is a useful reference. One item (Link to Figure 2) that was interesting was a technique for gastrostomy site closure. The authors describe passing 2 sutures through a long needle into the stomach around the stoma and using an endoscope/endoscopic biopsy forceps to redirect the sutures back through a catheter to make a loop which can be tied externally.
