Physical Prehabilitation in Patients who Underwent Major Abdominal Surgery: A Comprehensive Systematic Review and Component Network Meta-Analysis Using GRADE and CINeMA Approach.

Background: Physical prehabilitation is recommended before major abdominal surgery to ameliorate short-term outcomes.

Methods: A frequentist, random-effects network meta-analysis (NMA) was performed to clarify which type of preoperative physical activity among aerobic exercise (AE), inspiratory muscle training (IMT), and resistance training produces benefits in patients who underwent major abdominal surgery. The surface under the P-score, odds ratio (OR), or mean difference (MD) with a 95% confidence interval (CI) were reported.

Immunonutrition in patients who underwent major abdominal surgery: A comprehensive systematic review and component network metanalysis using GRADE and CINeMA approaches.

Background: The benefits of immunonutrition in patients who underwent major abdominal surgery have been recently established, but the optimal combination of immunonutrients has remained unclear. The aim is to clarify this point.

Methods: A systematic search of randomized clinical trials about immunonutrition in major abdominal surgery was made.

Value of immunonutrition in patients undergoing pancreatic resection: a trial sequential meta-analysis.

Background: The benefits of immunonutrition (IM) in patients who underwent pancreatic surgery are unclear.

Methods: A meta-analysis of randomized clinical trials (RCTs) comparing IM with standard nutrition (SN) in pancreatic surgery was carried out. A random-effects trial sequential meta-analysis was made, reporting Risk Ratio (RR), mean difference (MD), and required information size (RIS).

Trial sequential meta-analysis of laparoscopic versus open pancreaticoduodenectomy: is it the time to stop the randomization?

Background: The advantages of LPD compared with OPD remain debatable. The study aimed to compare the laparoscopic (LPD) versus open (OPD) for pancreaticoduodenectomy.

Methods: A meta-analysis of randomized studies (RCTs) comparing LPD and OPD was made.

Effect of malnutrition on postoperative results after pancreatic resection: An entropy balancing analysis.

Background & Aims: Malnutrition is a well-recognized risk factor for major surgery-related complications, but the impact of preoperative nutritional therapy is still debated due to a lack of high-level evidence. The study aims to evaluate the role of preoperative malnutrition in the postoperative course of patients who underwent pancreatic resection.

Methods: This is a retrospective study involving 488 patients who underwent pancreatic resection.

Preoperative carbohydrate loading before elective abdominal surgery: A systematic review and network meta-analysis of phase II/III randomized controlled trials.

Background & Aims: The preoperative use of carbohydrate loading (CHO) is recommended in patients undergoing abdominal surgery, even if the advantages remain debatable. The aim was to evaluate the CHO benefits in patients undergoing abdominal surgery.

Methods: A systematic search of randomized clinical trials was made.
