Review Meta Analysis Comparative Study
Fibrin glue versus staple for mesh fixation in laparoscopic transabdominal preperitoneal repair of inguinal hernia: a meta-analysis and systematic review.
The aim of this study was to compare outcomes of mesh fixation using fibrin glue versus staple in laparoscopic transabdominal preperitoneal (TAPP) repair of inguinal hernia. ⋯ Our meta-analysis and systematic review shows that the use of fibrin glue fixation may provide an alternative approach to staple fixation in TAPP inguinal hernia repair without increasing the postoperative morbidity. Large-scale RCTs with long-term follow-up are still needed to further assess postoperative outcomes such as chronic pain and disease recurrence.

Observational Study
The impact of a standardized program on short and long-term outcomes in bariatric surgery.
The purpose of this study was to determine whether there has been an improvement in short- and long-term clinical outcomes since 2010, when the Ontario Bariatric Network led a province-wide initiative to establish a standardized system of care for bariatric patients. The system includes nine bariatric centers, a centralized referral system, and a research registry. Standardization of procedures has progressed yearly, including guidelines for preoperative assessment and perioperative care.

Observational Study
Pneumoperitoneum deteriorates intratidal respiratory system mechanics: an observational study in lung-healthy patients.
Pneumoperitoneum during laparoscopic surgery leads to atelectasis and impairment of oxygenation. Positive end-expiratory pressure (PEEP) is supposed to counteract atelectasis. We hypothesized that the derecruiting effects of pneumoperitoneum would deteriorate the intratidal compliance profile in patients undergoing laparoscopic surgery. ⋯ Analyses of the intratidal compliance profiles reveal that pneumoperitoneum during laparoscopic surgery causes intratidal recruitment/derecruitment which partly persists after its removal. The analysis of the intratidal volume-dependent C RS profiles could be used to guide intraoperative PEEP adjustments during elevated intraabdominal pressure.

Laparoscopic ventral hernia repair (LVHR) with intraperitoneal mesh placement is well established; however, the fate of patients requiring future abdominal operations is not well understood. This study identifies the characteristics of LVHR patients undergoing reoperation and the sequelae of reoperation. ⋯ In a large consecutive series of LVHR, the rate of abdominal reoperation was 17 %. Generally, these reoperations can be performed safely. A reoperation for bowel obstruction, however, may carry an increased risk of EBR as a direct result of mesh-bowel adhesions. Secondary mesh infection after reoperation, although rare, may also occur. Surgeons should discuss with their patients the potential long-term implications of having an intraperitoneal mesh and how it may impact future abdominal surgery.

There is a trend toward shorter-stay bariatric surgery. However, reducing LOS may increase complications and post-discharge resource utilization. Our goal was to compare outcomes before and after implementation of short-stay bariatric surgery. ⋯ This study suggests that short-stay bariatric surgery is feasible and safe. Reducing the LOS from 2 to 1 day did not significantly increase the rate of hospital readmissions, ED visits or patient calls to our office. Further research is necessary to determine whether LOS can be further abbreviated to allow outpatient LSG and LRYGB.
