Rajiv Iyer, Kaisorn L Chaichana
BACKGROUND AND STUDY AIMS/OBJECTIVE:  Deep-seated high-grade gliomas (HGGs) represent a unique surgical challenge because they reside deep to critical cortical and subcortical structures and infiltrate functional areas of the brain. Therefore, accessing and resecting these tumors can often be challenging and associated with significant morbidity. We describe the use of minimally invasive approaches to access deep-seated HGGs to achieve extensive resections while minimizing surgical morbidity...

BACKGROUND: Chiari I malformations are common in adults, and a frequent procedure in neurosurgical practice. Despite a number of studies, to date there is no consensus about the indications or surgical technique for this common condition. Growing emphasis on value-based care has emphasized reduction of readmissions and reoperations, and is particularly relevant in Chiari, which has traditionally been associated with a high complication rate. OBJECTIVE: To provide a contemporary surgical profile of risk factors and complications for Chiari I malformations in adults...

Postoperative peritoneal adhesions, fibrous bands formed in the peritoneal cavity following surgery, represent a common, challenging and costly problem faced by surgeons and patients, for which effective therapeutic options are lacking. Since aberrant inflammation is one of the key mechanisms underlying peritoneal adhesion formation, here we set out to study the role of developmental endothelial locus-1 (Del-1), which has been recently identified as an endogenous inhibitor of inflammation, in the formation of postoperative peritoneal adhesions using a mouse model of peritoneal adhesions induced by ischemic buttons...

BACKGROUND: The pure laparoscopic approach to donor hepatectomy is being taken more often. However, few centers perform pure laparoscopic donor right hepatectomy (PLDRH) because it requires a high level of surgical skill. Studies reporting initial outcomes of PLDRH may prompt further implementation of the technique and help reduce initial learning curves at other transplant centers. This study reports performance of PLDRH at a single center with extensive experience of adult living donor liver transplantation...

The goal of our study was to compare the impact of pancreaticogastrostomy (PG) versus pancreaticojejunostomy (PJ) on the incidence of complications after pancreaticoduodenectomy. A systematic search was performed using RevMan 5.3 software. A meta-analysis showed that PG was not superior to PJ in terms of postoperative pancreatic fistula (POPF). In multicenter randomized controlled trials, the incidence of POPF was lower in patients undergoing PG than in those undergoing PJ. However, PG was associated with an increased risk of postoperative intraluminal hemorrhage, but no significant difference was observed between 2-layer PG and PJ...
