Multicenter Study Comparative Study
Perioperative outcomes of laparoscopic and robot-assisted major hepatectomies: an Italian multi-institutional comparative study.
Laparoscopic major hepatectomy (LMH), although safely feasible in experienced hands and in selected patients, is a formidable challenge because of the technical demands of controlling hemorrhage, sealing bile ducts, avoiding gas embolism, and maintaining oncologic surgical principles. The enhanced surgical dexterity offered by robotic assistance could improve feasibility and/or safety of minimally invasive major hepatectomy. The aim of this study was to compare perioperative outcomes of LMH and robotic-assisted major hepatectomy (RMH). ⋯ This retrospective multi-institution study confirms that selected patients can safely undergo minimally invasive major hepatectomy, either LMH or RMH. The fact that intermittent pedicle occlusion could be avoided in RMH suggests improved surgical ability to deal with bleeding during liver transection, but further studies are needed before any final conclusion can be drawn.

The influence of fluorescence imaging on the location of bowel transection during robotic left-sided colorectal surgery.
Hypoperfusion is an important risk factor for anastomotic leakage in colorectal surgery. This study was designed to evaluate the impact of fluorescence imaging on visualization of perfusion and subsequent change of transection line during left-sided robotic colorectal resections. ⋯ Fluorescence imaging provides additional information during determination of transection location in left-sided colorectal procedures. This results in a significant change of transection location, particularly at the proximal transection site. Further research needs to be conducted with larger patient cohorts and in comparative design to determine actual effect on anastomotic leak rate.

Cost savings for elective laparoscopic resection compared with open resection for colorectal cancer in a region of high uptake.
Previous cost analyses of laparoscopic resection for colorectal cancer (CRC) reported slightly higher or similar costs to those of open resection. These analyses were based on randomised controlled trials when the laparoscopic approach was newly adopted. This study compared costs for laparoscopic versus open resection in a region of high uptake where adoption is mature. ⋯ This non-randomised study in a region of high uptake found a similar operating time and lower cost for laparoscopic resection for CRC compared with those of open resection due to a shorter length-of-stay and shorter time in ICU. Laparoscopic resection for CRC saves money when the procedure is widely adopted and surgeons are experienced in the technique.

Elective antireflux surgery in the US: an analysis of national trends in utilization and inpatient outcomes from 2005 to 2010.
Previous research suggested that antireflux surgery reached its peak volume in the US more than a decade ago. Factors such as changes in population demographics and improvements in surgical outcomes may have reversed this decline. We sought to examine national trends in the management of antireflux surgery patients and identify patient and hospital characteristics associated with postoperative complications. ⋯ Today's antireflux surgery patient population is a higher-risk cohort, but complication rates have remained stable and inpatient mortality has declined more than 50 % over the past decade. Given these findings, additional research is needed to understand why antireflux surgery is underutilized, with a decline of more than two-thirds since its peak in 1999.

Approximately 175,000 umbilical hernia repairs are performed annually in the US. Controversy exists regarding the optimal approach for the elective repair of primary umbilical hernias. ⋯ This study identified potential decreased total and wound morbidity associated with LHR for elective primary umbilical hernia repairs at the expense of increased operative time, LOS, and respiratory and cardiac complications. These results should be considered within the context of a retrospective study with its inherent risks of bias and limitations.
