Extension of lymph node dissection in the surgical treatment of esophageal and gastroesophageal junction cancer: seven questions and answers.

The role of two- or three-field nodal dissection in the surgical treatment of esophageal and gastroesophageal junction cancer in the minimally invasive era is still controversial. This review aims to clarify the extension of nodal dissection in esophageal and gastroesophageal junctional cancer. A basic evidence-based analysis was designed, and seven research questions were formulated and answered with a narrative review.

Meta-analysis of warmed versus standard temperature CO2 insufflation for laparoscopic cholecystectomy.

Background: There is conflicting evidence for the use of warmed, humidified carbon dioxide (CO2) for creating pneumoperitoneum during laparoscopic cholecystectomy. Few studies have reported less post-operative pain and analgesic requirement when warmed CO2 was used.

Aim: This systematic review and meta-analysis aims to analyse the literature on the use of warmed CO2 in comparison to standard temperature CO2 during laparoscopic cholecystectomy.
