Randomized Controlled Trial
Short-term outcomes of single-site robotic cholecystectomy versus four-port laparoscopic cholecystectomy: a prospective, randomized, double-blind trial.
Randomized studies could not demonstrate significant outcome benefit after single-incision laparoscopic cholecystectomy compared to classic four-port laparoscopic cholecystectomy (CLC). The new robotic single-site platform might offer potential benefits on local inflammation and postoperative pain due to its technological advantages. This prospective randomized double-blind trial compared the short-term outcomes between single-incision robotic cholecystectomy (SIRC) and CLC. ⋯ SIRC does not offer any significant reduction of postoperative pain compared to CLC. SIRC patients unaware of their type of operation still report pain in extra-umbilical sites like after CLC. The cosmetic advantage of SIRC should be balanced against an increased risk of incisional hernias and higher costs.

Anastomotic leakage after colorectal surgery is a severe complication. One possible cause of anastomotic leakage is insufficient vascular supply. The aim of this study was to evaluate the feasibility and the usefulness of intraoperative assessment of vascular anastomotic perfusion in colorectal surgery using indocyanine green (ICG)-enhanced fluorescence. ⋯ ICG-enhanced fluorescent angiography provides useful intraoperative information about the vascular perfusion during colorectal surgery and may lead to change the site of resection and/or anastomosis, possibly affecting the anastomotic leak rate. Larger further randomized prospective trials are needed to validate this new technique.

Comparative Study
Comparison of open, laparoscopic, and robotic approaches for total abdominal colectomy.
The utilization of minimally invasive surgery is increasing in colorectal surgery. We sought to compare the outcomes of patients who underwent elective open, laparoscopic, and robotic total abdominal colectomy. ⋯ Minimally invasive approaches to total colectomy are safe, with the advantage of lower mortality and morbidity compared to an open approach. Although there was no significant difference in the morbidity between minimally invasive approaches, robotic surgery had a significantly lower conversion rate compared to laparoscopic approach. Total hospital charges are significantly higher in robotic surgery compared to laparoscopic approach.

Observational Study
Neonatal brain oxygenation during thoracoscopic correction of esophageal atresia.
Little is known about the effects of carbon dioxide (CO2) insufflation on cerebral oxygenation during thoracoscopy in neonates. Near-infrared spectroscopy can measure perioperative brain oxygenation [regional cerebral oxygen saturation (rScO2)]. ⋯ The impact of neonatal thoracoscopic repair of EA with insufflation of CO2 at 5 mmHg was studied. Intrathoracic CO2 insufflation caused a reversible decrease in SaO2 and pH and an increase in paCO2. The rScO2 was higher at anesthesia induction but remained stable and within normal limits during and after the CO2 pneumothorax, which suggest no hampering of cerebral oxygenation by the thoracoscopic intervention. Future studies will focus on the long-term effects of this surgery on the developing brain.

LSG is widely accepted as a definitive treatment for obesity. Due to lack of large series with long-term follow-up, disagreement remains regarding its safety and efficacy. We present a series of 1020 consecutive LSGs performed with long-term follow-up. ⋯ This study confirms that LSG is safe and has very low rates of early and long-term complications when compared to other well-established procedures. Additionally, LSG that appears results in significant improvement of obesity-related comorbid conditions.
