Randomized Controlled Trial
[Pain management after hemorrhoidectomy. Patient-controlled analgesia vs conventional pain therapy].
The aim of this randomized non-blinded study was to assess the pain management after hemorrhoidectomy using patient-controlled analgesia (PCA). ⋯ Pain after hemorrhoidectomy can be reduced within the first 24 h using PCA. Patients are significantly more satisfied with PCA than with standard medication.

Randomized Controlled Trial Comparative Study
[Analgesia in colon surgery. Can the use of NSAIDs reduce the opioid consumption following conventional and laparoscopic interventions?].
The goal of our study was to evaluate the morphine-sparing effect of nonsteroidal anti-inflammatory drugs (NSAIDs) following both conventional and laparoscopic colon surgery. ⋯ The use of NSAIDs following colon surgery significantly reduces postoperative opioid consumption.

Randomized Controlled Trial Comparative Study
[Early chest tube removal after video-assisted thoracoscopic surgery. Results of a prospective randomized study].
Chest tubes frequently cause postoperative patient discomfort after video-assisted thoracoscopic surgery (VATS). Therefore, a prospective randomized study was conducted to analyze whether early chest tube removal within 2 h postoperatively is justified in VATS. ⋯ Early chest tube removal after video-assisted thoracoscopic wedge resection is recommended. The inclusion and exclusion criteria of this study should be considered for future early chest tube removal. Long-term follow-up will clarify if early chest tube removal also leads to a reduction in chronic pain.

Randomized Controlled Trial Comparative Study Clinical Trial
[3-dimensional computer animation--a new medium for supporting patient education before surgery. Acceptance and assessment of patients based on a prospective randomized study--picture versus text].
The rigorous implementation of clear preoperative information is mandatory for the patient's understanding, acceptance and written informed consent to all diagnostic and surgical procedures. In the present study, I evaluated whether new media are suitable for conveying basic information to patients; I analysed the merits of computerized animation to illustrate a difficult treatment process, i.e., the progressive steps of a thyroid operation, in comparison to the use of conventional flyers. ⋯ Preoperative surgical information can be optimized by presenting the operative procedure via computer animation. Nowadays, several types of new media such as the world wide web, CD, DVD, and digital TV are readily available and--as shown here--suitable for effective visual explanation. Most patients are familiar with acquiring new information by one of these means. An appropriately designed 3D repre-sentation is met with a high level of acceptance, as the present study clearly shows. Modern patient-based information systems are necessary. They can no longer be the sole responsibility of the medical profession, but must be on the agenda of hospital managements and of medical care systems as well.
