Meta Analysis Comparative Study
Early versus delayed cholecystectomy for acute cholecystitis: a meta-analysis of randomized controlled trials.
We performed a meta-analysis of randomized controlled trials to determine the optimal timing of laparoscopic cholecystectomy and open cholecystectomy for acute cholecystitis. ⋯ There is no advantage to delaying cholecystectomy for acute cholecystitis on the basis of outcomes in mortality, morbidity, rate of conversion to open surgery, and mean hospital stay. Thus, early cholecystectomy should be performed for patients with acute cholecystitis.

Comparative Study
Unilateral post-traumatic pulmonary contusion: findings of a review.
There is still much controversy regarding the optimal treatment for pulmonary contusion. Therefore, we examined the variables affecting patient outcomes over a 10-year period. ⋯ Optimizing patient outcome requires prompt diagnosis, appropriate maintenance of fluid volume, and selective mechanical ventilation.

Comparative Study
Diagnostic peritoneal lavage for diagnosing blunt hollow visceral injury: the accuracy of two different criteria and their combination.
To test the usefulness of diagnostic peritoneal lavage (DPL) for identifying blunt hollow visceral injury with two different sets of criteria or a combination of the two. ⋯ Although each criterion alone is very accurate in predicting the presence of blunt hollow visceral injury, the combined use of the two would further improve the accuracy of the diagnosis and thereby reduce the number of unnecessary celiotomies.

We examined the changes in evoked spinal cord potentials (ESCP) during profound hypothermic circulatory arrest to estimate the safe ischemic time. ⋯ When an ESCP disappeared, ischemic spinal cord injury had occurred. This demonstrates the potential value of estimating the time of disappearance of ESCPs to prevent ischemic spinal cord injury during descending thoracic aortic surgery.

We evaluated the purpose reliability and validity of a preliminary scale, which we developed to assess postoperative dysfunction after surgery for gastric and esophageal carcinoma. ⋯ Our preliminary scale is sufficiently reliable and valid, and will prove to be clinically useful.
