Randomized Controlled Trial Multicenter Study
Endoscopic ablation of intestinal metaplasia containing high-grade dysplasia in esophagectomy patients using a balloon-based ablation system.
This study aimed to determine the optimal treatment parameters for the ablation of intestinal metaplasia (IM) containing high-grade dysplasia (HGD) using a balloon-based ablation system for patients undergoing esophagectomy. ⋯ Complete ablation of IM-HGD without ablation of submucosa is possible using the HALO360 system. Ablation depth is dose related and limited to the muscularis mucosae. In one patient, small residual foci of IM-HGD at the edge of the ablation zone were attributable to incomplete overlap, which can be avoided. This study, together with nonesophagectomy IM-HGD trials currently underway, will identify the optimal treatment parameters for IM-HGD patients who would otherwise undergo esophagectomy or photodynamic therapy.

Randomized Controlled Trial Comparative Study
Comparison of dexamethasone, metoclopramide, and their combination in the prevention of postoperative nausea and vomiting after laparoscopic cholecystectomy.
Postoperative nausea and vomiting (PONV) are one of the most common complaints following anesthesia and surgery. This study was designed to evaluate the efficacy of dexamethasone, metoclopramide, and their combination to prevent PONV in patients undergoing laparoscopic cholecystectomy. ⋯ Dexamethasone and the combination of dexamethasone plus metoclopramide were more effective in preventing PONV than metoclopramide and placebo.

Intraperitoneal aerosolization of bupivacaine reduces postoperative pain in laparoscopic surgery: a randomized prospective controlled double-blinded clinical trial.
Laparoscopic strategies for managing intraabdominal pathologies offer significant benefits compared with conventional approaches. Of interest are reports of decreased postoperative pain, resulting in shorter hospitalization and earlier return to normal activity. However, many patients still require strong analgesia postoperatively. This study analyzed the use of intraoperatively delivered aerosolized intraperitoneal bupivacaine and its ability to reduce postoperative pain. ⋯ Aerosolized intraperitoneal local anesthetic is an effective method for controlling postoperative pain. It significantly helped to reduce opiate use and contributed to rapid mobilization, leading to short hospitalization and possible reduction in treatment cost.

Randomized Controlled Trial Comparative Study
Comparison of therapeutic effectiveness of percutaneous drainage with antibiotics versus antibiotics alone in the treatment of periappendiceal abscess: is appendectomy always necessary after perforation of appendix?
The present study was designed to compare the therapeutic effectiveness of percutaneous drainage with antibiotics versus antibiotics alone in the treatment of appendicitis complicated by periappendiceal abscess. ⋯ Percutaneous drainage with antibiotics is a safe and effective way of treating acute perforated appendicitis. The recurrence rate for these patients is relatively low, and very often interval appendectomy is not required. For patients with periappendiceal abscess > or = 3 cm in diameter, antibiotic therapy alone is insufficient and the recurrence rate is high.

Randomized Controlled Trial
Prospective randomized controlled trial of laparoscopic trainers for basic laparoscopic skills acquisition.
Laparoscopic surgery requires a different set of skills than traditional open surgery. The acquisition of basic laparoscopic skills may help novices when learning laparoscopic procedures. This study tested the hypothesis that the combination of virtual reality and box trainers leads to better basic laparoscopic skill acquisition than either method alone or no training. ⋯ Our data demonstrate that the combination of virtual reality training and inanimate box training leads to better laparoscopic skill acquisition than either training method alone or no training at all. Optimal preclinical laparoscopic training should incorporate both virtual reality trainers and inanimate box trainers.
