Randomized Controlled Trial
Lower intra-abdominal pressure has no cardiopulmonary benefits during laparoscopic colorectal surgery: a double-blind, randomized controlled trial.
Higher intra-abdominal pressure may impair cardiopulmonary functions during laparoscopic surgery. While 12-15 mmHg is generally recommended as a standard pressure, the benefits of lower intra-abdominal pressure are unclear. We thus studied whether the low intra-abdominal pressure compared with the standard pressure improves cardiopulmonary dynamics during laparoscopic surgery. ⋯ We observed few cardiopulmonary benefits but poor surgical conditions in the low intra-abdominal pressure during laparoscopy. Considering cardiopulmonary dynamics and surgical conditions, the standard intra-abdominal pressure may be preferable to the low pressure for laparoscopic surgery.

Comparative Study
Pure laparoscopic right hepatectomy of living donor is feasible and safe: a preliminary comparative study in China.
The adoption of laparoscopic techniques for living donor major hepatectomy has been controversial issue. The aim of this study is to present the preliminary experience of laparoscopic right hepatectomy in China. ⋯ Laparoscopic approaches for right hepatectomy contribute to less blood loss, better cosmetic satisfaction, less severe complications, and faster rehabilitation. PLRH is a safe and feasible procedure, which must be performed in highly specialized centers with expertise of both LDLT and laparoscopic hepatectomy, and requires a hybrid-to-pure stepwise development.

Randomized Controlled Trial
Randomized clinical trial comparing laparoscopic hiatal hernia repair using sutures versus sutures reinforced with non-absorbable mesh.
Current literature is characterized by a discrepancy between reported symptomatic and radiological recurrent hiatal hernia's following primary repair. Crural augmentation using mesh is suggested to reduce recurrence rates. The aim of this trial is to analyze 1-year outcome of laparoscopic hiatal hernia repair using sutures versus sutures reinforced with non-absorbable mesh. ⋯ Use of non-absorbable mesh to reinforce primary hiatal hernia repair results in equal hiatal hernia recurrence and symptomatic outcome compared to repair using sutures alone. During 1-year follow-up, there were no mesh-related complications. Follow-up beyond 1 year needs to demonstrate whether these findings are sustained.

Minimally invasive esophagectomy (MIE) for patients with esophageal cancer has recently spread worldwide. However, whether MIE is less invasive has not yet been fully evaluated. ⋯ MIE significantly attenuated postoperative serum CRP levels compared with OE. MIE could contribute to improved survival.

The long-term outcomes of robotic-assisted laparoscopic lateral lymph node dissection (RALLD) have not been fully investigated. This study aimed to assess the oncological and long-term outcomes of RALLD for rectal cancer through comparison with those of open lateral lymph node dissection (OLLD) in a retrospective study. ⋯ The short- and long-term outcomes indicated that RALLD may be a useful modality for locally advanced low rectal cancer.
