Successful preoperative identification of fish bone causing appendicitis using 3-dimensional multidetector-CT.

A 79 years male with fishbone-induced acute appendicitis was treated surgically with laparoscopic procedure. In preoperative diagnostic study, 3-dimensional multidetector-computed tomography (3D-MDCT) demonstrated the foreign body in the appendix and 3D-reconstructed images seemed fishbone with sharp-pointed dorsal fin directing to the tip of the appendix. With these findings, surgical indication of appendectomy was confirmed and laparoscopic appendectomy was performed.

Influence of exogenous fat emulsion on pulmonary gas exchange after major surgery.

The use of fat emulsion in total parenteral nutrition (TPN) is closely related to changes in respiratory function. The aim of this study was to evaluate the influence of exogenous fat emulsion on pulmonary gas exchange in the early period after major surgery. Total parenteral nutrition was administered to 18 patients for 6 days after esophagectomy for carcinoma.
