Multicenter Study
The 90-day mortality and the subsequent renal recovery in critically ill surgical patients requiring acute renal replacement therapy.
Particular attention should be paid to postoperative patients that suffer from severe acute kidney injury (AKI) requiring renal replacement therapy (RRT). ⋯ The development of AKI requiring RRT in postoperative critical patients represents a substantial risk for mortality and morbidity.

This study examined the methodologic quality of medical education research published in The American Journal of Surgery (AJS) relative to other journals and in AJS itself over time. ⋯ Education studies published in AJS compared favorably with those published in other journals, and this quality was maintained over time. Nonetheless, there is room for improvement with respect to study designs and outcome assessment.

There is no conclusive evidence which size of suture stitches and suture distance should be used to prevent burst abdomen and incisional hernia. ⋯ Small stitches with small suture distances achieve higher tensile forces than large stitches with large suture distances. Therefore, small stitches may be useful to prevent the development of a burst abdomen or an incisional hernia after midline incisions.

Comparative Study
Comparison of laparoscopy-assisted and open pylorus-preserving pancreaticoduodenectomy for periampullary disease.
Although many reports have described laparoscopic pancreatic surgery, pancreaticoduodenectomy (PD) has not been widely accepted. The present study aimed to compare laparoscopy-assisted and open pylorus-preserving pancreaticoduodenectomy (PPPD) to investigate the feasibility, safety, and tumor clearance. ⋯ Laparoscopy-assisted PPPD is on the same level with conventional open surgery in terms of perioperative outcomes or treatment efficacy.

Recently, studies have been conducted examining the efficacy of 3% hypertonic saline solution (HS) for the treatment of traumatic brain injury; however, few studies have analyzed the effects of 3% hemorrhagic shock during hemorrhagic shock. The aim of this study was to test the potential immunomodulatory benefits of 3% hemorrhagic shock resuscitation over standard fluid resuscitation. ⋯ A small-volume resuscitation strategy modulates the inflammatory response and decreases end-organ damage after HS. Three percent HS provides immunomodulatory and metabolic effects similar to those observed with conventional concentrations of HS.
