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.

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.

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.

Multicenter Study Controlled Clinical Trial
The LINX® reflux management system: confirmed safety and efficacy now at 4 years.
Sphincter augmentation with the LINX® Reflux Management System is a surgical option for patients with chronic gastroesophageal disease (GERD) and an inadequate response to proton pump inhibitors (PPIs). Clinical experience with sphincter augmentation is now available out to 4 years. ⋯ Sphincter augmentation with the LINX Reflux Management System provided long-term clinical benefits with no safety issues, as demonstrated by reduced esophageal acid exposure, improved GERD-related quality of life, and cessation of dependence on PPIs, with minimal side effects and no safety issues. Patients with inadequate symptom control with acid suppression therapy may benefit from treatment with sphincter augmentation.

Randomized Controlled Trial Comparative Study
Transvaginal cholecystectomy versus single-incision laparoscopic cholecystectomy versus four-port laparoscopic cholecystectomy: a prospective cohort study.
This report describes the first prospective cohort study comparing transvaginal cholecystectomies (TVC) with single incision laparoscopic cholecystectomies (SILC) and four-port laparoscopic cholecystectomies (4PLC). ⋯ Transvaginal cholecystectomy is a safe and well-tolerated procedure with statistically significantly less pain at 1 and 3 days after surgery, with a faster return to work but longer operative times compared with single incision and four-port laparoscopic cholecystectomy.
