Laparoscopic surgery involves the creation of a carbon dioxide (CO2) pneumoperitoneum to facilitate a clear surgical view, which may result in an elevated intracranial pressure (ICP). Depending on the surgical area, steep Trendelenburg positioning may be used as well, further increasing the ICP. The objective of this study was to assess the effects of laparoscopic surgery on changes in ICP assessed by ultrasonographic measurement of optic nerve sheath diameter (ONSD), which is a generally accepted simple, reliable, and non-invasive ICP measurement technique. ⋯ The current meta-analysis revealed that ICP elevation during laparoscopy could be anticipated through a significant increase in the ONSD in the early (0-30 min) and late (30-120 min) periods during CO2 pneumoperitoneum.

Review Meta Analysis
Incidence of incisional hernia in the specimen extraction site for laparoscopic colorectal surgery: systematic review and meta-analysis.
The incidence of incisional hernia(IH) may be affected by the choice of specimen extraction incision. The objective of this study was to perform a systematic review and meta-analysis comparing the incidence of IH after midline and off-midline incisions in patients undergoing laparoscopic colorectal surgery. ⋯ Midline incisions for specimen extraction in laparoscopic colorectal surgery are at significantly higher risk of IH compared to off-midline (transverse or Pfannenstiel) incisions, but these data are of poor quality and heterogeneous.

Several studies have been investigated to find the long-term effect of bariatric surgery on weight loss; nevertheless, a meta-analysis can detailedly demonstrate the effect of bariatric surgery on weight in morbidly obese patients. This study aimed to assess the long- and very long-term effects of laparoscopic adjustable gastric banding (LAGB), laparoscopic Roux-en-Y gastric bypass (LRYGB), and laparoscopic sleeve gastrectomy (LSG) on weight loss in adults. ⋯ These findings suggest that LRYGB is an effective procedure in morbidly obese patients that leads to sustainable weight loss over the long- and very long-term periods in compared with LAGB and LSG.

Review Meta Analysis Comparative Study
Systematic review and meta-analysis of robotic versus open pancreaticoduodenectomy.
Although robotic pancreaticoduodenectomy (RPD) has been successfully performed since 2003, its advantages over open pancreaticoduodenectomy (OPD) are still uncertain. The aim of this systematic review and meta-analysis was to compare the clinical outcomes of RPD to those of OPD. ⋯ According to the results of this meta-analysis, RPD is as safe and efficient as OPD and is even favourable in terms of margin-negative resection, overall complication and wound infection rates and length of hospital stay. Given that there have not yet been any high-quality randomized controlled trials (RCTs), the evidence is still limited. Additional prospective, multi-centre RCTs are needed to further define the role of the robotic technique in PD.

Review Meta Analysis
LINX® magnetic esophageal sphincter augmentation versus Nissen fundoplication for gastroesophageal reflux disease: a systematic review and meta-analysis.
The LINX® magnetic sphincter augmentation system (MSA) is a surgical technique with short-term evidence demonstrating efficacy in the treatment of medically refractory or chronic gastroesophageal reflux disease (GERD). Currently, the Nissen fundoplication is the gold-standard surgical treatment for GERD. We are the first to systematically review the literature and perform a meta-analysis comparing MSA to the Nissen fundoplication. ⋯ Magnetic sphincter augmentation appears to be an effective treatment for GERD with short-term outcomes comparable to the more technically challenging and time-consuming Nissen fundoplication. Long-term comparative outcome data past 1 year are needed in order to further understand the efficacy of magnetic sphincter augmentation.
