Esophageal cancer - self-expanding tracheal fistula capsule metal stent implantation

Mark through the esophagus . Week due to fistula patients and lung tissue severe mediastinal infection, poor physical fitness . Stent implantation in the whole process should be sterile operation, so as not to aggravate the infection , life-threatening . Determine the lesion on the community and the fistula to be absolutely accurate,[link widoczny dla zalogowanych], the first imaging of esophageal intubation,[link widoczny dla zalogowanych], positioning and the establishment of bone tracer marker map or set , will run into the outer sheath after the device should be re- positioned within the stent when the sheath mouth when they sent Re- positioning is correct, to release the stent . Stent positioning is the most critical technology, once the stent in place, non-surgical difficult to remove , need to re- implant a stent . Expanding stent implantation is not sufficient , not balloon with stent expansion ,[link widoczny dla zalogowanych], because expansion can cause severe pain for a long time . Self- expandable stent expansion depend on the inherent strength, 3 to 7 days to complete the expansion , the surrounding tissue gradually adapt to this expansion , the pain will be much lighter . 4. Support measures : ( 1) anti-infection . Continuous use of antibiotics until the infection disappears , is an important measure to save the patient's life . Within this group I patients died from pulmonary infection after stent implantation , from the number of hospital several times after esophageal contrast barium enema when poured into the fistula and deposition in the lungs, unable to control the deadly lung inflammation . (2 ) correction of electrolyte disorders and nutritional disorders . Patients with long-term fasting. Electrolyte imbalance and nutritional failure times life-threatening , gastrointestinal tract, long empty, significantly decreased digestive function . After stent implantation a small amount of liquid should slowly from the transition to the large amounts of solid food , this time also add electrolytes and intravenous nutrition. (3 ) anti-cancer treatment. Infection control after stent implantation , physical improvements to continue to radiotherapy or chemotherapy, 6 patients in this group did not receive continued cancer treatment ,[link widoczny dla zalogowanych], 3 patients were died of cancer at 6,7,[link widoczny dla zalogowanych],6 months, transfer or complications. Short-term stenting may improve patient survival and improve quality of life , but long-term results still have to rely on anti-cancer treatment. The stent is to continue to ensure that anti-cancer therapy , is worth promoting.
