Randomized Controlled Trial
Effects of preoperative carbohydrates drinks on immediate postoperative outcome after day care laparoscopic cholecystectomy.
Postoperative nausea and vomiting is the most common cause for unexpected hospital admission of patients undergoing day care surgery. Overnight fasting changes patient metabolic state and influences their perioperative stress response. Preoperative carbohydrate loading may have accelerated recovery and better overall outcome after major abdominal surgery. The aim of the study was to investigate the effects of preoperative carbohydrate-rich drinks on postoperative nausea and vomiting and pain after day care laparoscopic cholecystectomy. ⋯ Perioperative consumption of a carbohydrate-rich drink can minimize postoperative nausea, vomiting and pain in patients undergoing outpatient cholecystectomy. Consumption of carbohydrate drinks up to 2 h prior to surgery is not associated with additional complications.

Minimally invasive surgery (MIS) has emerged as a treatment of choice for early-stage gastric cancer. However, applying MIS to gastric patients with high body mass index (BMI) is technically challenging, especially when performing D2 lymphadenectomy. Recently, robotic systems have been adopted to overcome the technical limitations of conventional laparoscopic surgery. Nevertheless, studies on the impact of the use of robotic systems to perform D2 lymphadenectomy in high BMI patients are lacking. Accordingly, this study was designed to compare the quality of lymphadenectomy, together with surgical outcomes, by robotic distal subtotal gastrectomy with D2 lymphadenectomy (RDGD2) to those by laparoscopic distal subtotal gastrectomy with D2 lymphadenectomy (LDGD2) in patients of different BMI status. ⋯ The benefits of a robotic approach were more evident in high BMI patients than in normal BMI patients when performing distal subtotal gastrectomy with D2 lymphadenectomy, particularly in terms of blood loss and consistent quality of lymphadenectomy. Robotic surgery could be an effective alternative to conventional laparoscopic surgery in treating gastric cancer patients with high BMI.

Considering the low incidence of colon cancer after an initial episode of colonic diverticulitis in some categories of patients, some authors suggested to exempt them from colonoscopy. However, this incidence has never been compared to that of a reference population, and predictors of cancer are still poorly investigated. We aimed to determine the 1-year incidence of colon cancer at the site of diverticulitis in patients diagnosed with left colonic or sigmoid acute diverticulitis, to compare this incidence to a reference population to state whether endoscopy is required or not, and to identify predicting factors of cancer to better target subpopulations needing that examination. ⋯ Colonoscopy should be continued after an initial diagnosis of left colonic or sigmoid acute diverticulitis, irrespective of the clinical or radiological presentations.

Review Comparative Study
Comprehensive complication index for NOTES procedures: results from a randomized controlled trial and comparison to published NOTES complication data.
This investigation uses the comprehensive complication index (CCI) to compare complications after natural orifice transluminal endoscopic surgery (NOTES) procedures. ⋯ The CCI results in a single, easily comparable complication index for surgical procedures whereas the CSC yields tabular results. A significant difference in interpretation occurs with variation in definition of complications. Average CCIs below a value of 10 describe low complication rates. Authors need to describe their definition of complications if using the CSC and the CCI. More emphasis should be given to reporting of minor complications. The use of the CCI for NOTES procedures will enable international comparison.

Laparoscopic versus open liver resection for hepatocellular carcinoma in posterosuperior segments.
Traditional open liver resection remains the classic procedure for hepatocellular carcinoma (HCC) located in the posterosuperior segments of the liver (segments I, IVa, VII, and VIII). This study compared the perioperative and oncologic results for laparoscopic versus open liver resection of HCC located in the posterosuperior segments, especially in patients with cirrhosis. ⋯ LLR for selected patients with HCC in the posterosuperior segments may offer the same oncologic outcomes as conventional procedures, while being associated with such advantages as lower blood loss, fewer postoperative complications, and shorter hospital stay.
