Objective To investigate the effect of enhanced recovery after surgery (ERAS) on stress hyperglycemia in patients after pancreaticoduodenectomy (PD). Methods Patients matched inclusion and exclusion standards were divided into two groups. The patients after PD before the implementation of ERAS programme were named as the control group (40 cases). The patients after PD with the implementation of ERAS programme were named as the experimental group (52 cases). The fast blood glucose (FBG) in postoperative day (POD) 1, 3, 7 and the volatility of capillary blood glucose during postoperative 3 days were compared between the two groups. Results The FBG in POD1, POD3, POD7 were (8.27 ± 1.99), (6.78 ± 1.22), (5.97 ± 1.21) mmol/L in the experimental group respectively, and the FBG in POD1, POD3, POD7 were (10.46 ± 5.17), (7.88 ± 2.98), (7.29 ± 2.94) mmol/L in the control group respectively, there were significant differences between two groups (t=2.545, 2.219, 2.683, all P<0.05). The volatility of capillary blood glucose during postoperative 3 days in the experimental group were (3.47± 1.98), (3.16 ± 1.46), (2.74 ± 1.49) mmol/L respectively, and the volatility of capillary blood glucose during postoperative 3 days in the control group were (4.13±2.36), (3.26±1.59), (4.07±2.74) mmol/L respectively, no significant differences were found in the volatility of capillary blood glucose in POD1 and POD2 between the two groups (t=1.479, 0.308, all P > 0.05), while significant differences were found in the volatility of capillary blood glucose in POD3 between the two groups (t=2.739, P<0.05). Conclusions It can be concluded that ERAS may be useful to decrease stress hyperglycemia and the volatility of capillary blood glucosein patients after PD, and accelerate the recovery of patients after PD.

Objective To evaluate the clinical application and safety of CT-guided transthoracic cutting needle lung biopsy in diagnosing diffuse lung diseases. Methods By using automatic biopsy gun (14 & 16 gauge), CT-guided transthoracic cutting needle lung biopsy was performed in 29 cases with diffuse lung diseases. The samples obtained were sent for pathological and immunohistochemical examination. The sampling successful rate, the diagnostic accuracy and the occurrence of complications were analyzed. Results Technical success rate was 100%, and large size of sample enough for pathological and immunohistochemical examination was obtained in all 29 cases. Definite pathological diagnosis could be made in 25 cases, with the positive diagnostic rate of 82.8%. The main complications included pneumothorax and pulmonary hemorrhage. The symptoms in most cases were not severe and disappeared within one week after the treatment. Conclusion For the diagnosis of diffuse lung diseases, CT-guided transthoracic cutting needle lung biopsy is a safe, easy, effective and reliable method with high successful rate, high diagnostic value and fewer complications, in these respects this technique is superior to transbronchial lung biopsy, open lung biopsy and video-assisted thoracoscopic lung biopsy. Therefore, this technique should be popularized in clinical practice.
