Enteral nutrition and quality of life in patients undergoing chemoradiotherapy for esophageal carcinoma: a comparison of nasogastric tube, esophageal stent, and ostomy tube feeding.

BACKGROUND AND AIMS: This study prospectively recruited esophageal squamous cell carcinoma patients who received esophageal stent, nasogastric tube (NGT), or jejunostomy/gastrostomy feeding to compare the changes in nutritional status and quality of life during chemoradiation therapy (CRT). METHODS: In total, 81 patients were analyzed (stent, 7; surgical ostomy, 26; NGT, 19; oral intake, 29). An NGT was inserted when, despite medication, dysphagia or pain worsened with oral feeding during CRT. Serial body weight and daily narcotic demand were recorded. Changes in serum albumin level and quality of life were also assessed. In subgroup analysis comparing NGT and prophylactic surgical ostomy feeding, 5 patients with total occlusion in the ostomy group were excluded. RESULTS: Patients in all groups had similar decreases in mean body weight with an overall change of -6.41% ± 5.21% at the end of CRT. The stent group had significantly worse pain, decreased albumin (-1.03 ± .9 mg/dL), and decreased quality of life across CRT compared with the other groups. In subgroup analysis the stent group had significantly higher weight loss, whereas the NGT group had higher narcotic demand and slightly worse quality of life. Two patients (7.7%) had ileus days after jejunostomy creation. Five patients (23.8%) among those received prophylactic ostomy creation and scarcely used it. CONCLUSIONS: These preliminary results raise concerns that use of esophageal stents may be less suitable in patients undergoing CRT. Tube feeding by means of transnasal or percutaneous routes appear to be comparably effective during CRT, but both have advantages and disadvantages. We suggest a careful endoscopic evaluation to select the population more appropriate for NGT feeding on an as-needed basis during CRT.

The effect of Helicobacter pylori eradication on the levels of essential trace elements.

OBJECTIVE: This study was designed to compare the effect of Helicobacter pylori (H. pylori) infection treatment on serum zinc, copper, and selenium levels. PATIENTS AND METHODS: We measured the serum zinc, copper, and selenium levels in H. pylori-positive and H. pylori-negative patients. We also evaluated the serum levels of these trace elements after H. pylori eradication. These serum copper, zinc, and selenium levels were determined by inductively coupled plasma mass spectrometry. RESULTS: Sixty-three H. pylori-positive patients and thirty H. pylori-negative patients were studied. Serum copper, zinc, and selenium levels had no significant difference between H. pylori-positive and H. pylori-negative groups. There were 49 patients with successful H. pylori eradication. The serum selenium levels were lower after successful H. pylori eradication, but not significantly (P = 0.06). There were 14 patients with failed H. pylori eradication. In this failed group, the serum selenium level after H. pylori eradication therapy was significantly lower than that before H. pylori eradication therapy (P < 0.05). The serum zinc and copper levels had no significant difference between before and after H. pylori eradication therapies. CONCLUSION: H pylori eradication regimen appears to influence the serum selenium concentration (IRB number: KMUH-IRB-20120327).
