Randomized Controlled Trial Multicenter Study
Drain after elective laparoscopic cholecystectomy. A randomized multicentre controlled trial.
Routine drainage after laparoscopic cholecystectomy is still debatable. The present study was designed to assess the role of drains in laparoscopic cholecystectomy performed for nonacutely inflamed gallbladder. ⋯ The present study was unable to prove that the drain was useful in elective, uncomplicated LC.

Randomized Controlled Trial Comparative Study
Single-incision versus conventional laparoscopic colectomy for colonic neoplasm: a randomized, controlled trial.
Single-incision laparoscopic colectomy (SILC) is a newly developed procedure with the benefit of better cosmetic outcome and potentially reduced wound pain compared with conventionally laparoscopic colectomy (CLC). However, the application of SILC requires careful evaluation to prove its benefit and safety. This randomized, controlled study compared the operative outcome of patients who underwent SILC and CLC. ⋯ In a selected group of patients with small tumor and good operative risk, SILC is a safe alternative to CLC. Single-port laparoscopic colectomy also is associated with the benefits of less postoperative pain and shorter hospital stay than CLC.

Comparative Study Clinical Trial
Damage control strategy for the management of perforated diverticulitis with generalized peritonitis: laparoscopic lavage and drainage vs. laparoscopic Hartmann's procedure.
This study was designed to compare laparoscopic peritoneal lavage and drainage (LLD) with laparoscopic Hartmann's procedure (LHP) in the management of perforated diverticulitis and to investigate a safer and more effective laparoscopic method for managing acute perforated diverticulitis with generalized peritonitis. ⋯ Both LHP and LLD can be performed safely and effectively for managing severe diverticulitis with generalized peritonitis. Compared with LHP, LLD does not remove the pathogenic source; however, the clinical application of this damage control operation to our patients showed significantly better short- and long-term clinical outcomes for managing perforated diverticulitis with various Hinchey classifications.

Surgery has been associated with proangiogenic plasma protein changes that may promote tumor growth. Angiopoietin-like protein 4 (ANGPTL4) is expressed by endothelial cells and other tissues in response to hypoxia. Both intact ANGPTL4 and its partly degraded C-terminal fragment may promote tumor angiogenesis. This study had two purposes: to measure and compare preoperative plasma ANGPTL4 levels in patients with colorectal cancer (CRC) and benign colorectal disease (BCD) and to determine plasma levels after minimally invasive colorectal resection (MICR) for CRC. ⋯ CRC is associated with lower preoperative plasma ANGPTL4 levels compared with BCD, and the levels may vary inversely with disease severity. After MICR for CRC, levels are significantly lower for over a month compared with the preoperative level; the cause for this persistent decrease is unclear. The implications of both the lower preoperative level and the persistently decreased postoperative levels are unclear. Further studies are needed.

Randomized Controlled Trial
Randomized double-blind placebo-controlled study of the efficacy of continuous infusion of local anesthetic to the diaphragm closure following laparoscopic hiatal hernia repair.
Laparoscopic repair of hiatal hernia can result in significant postoperative pain requiring use of narcotics and patient dissatisfaction. A catheter-based delivery method that has demonstrated effectiveness and safety in other laparoscopic and open procedures (ON-Q, I Flow Corporation) was used to deliver pain medicine. This randomized double-blind, placebo-controlled study evaluated the efficacy of continuous infusion of local anesthetic to the diaphragm closure post laparoscopic hiatal hernia repair. ⋯ This randomized double-blind, placebo-controlled trial showed no advantage in using the ON-Q pain pump in terms of providing measurable reduction of pain or concomitant narcotic or nausea medication use. Further studies are indicated to determine alternatives for reducing postoperative pain after laparoscopic hiatal hernia repair.
