Multicenter Study
"Fast track surgery" in the north-west of Italy: influence on the orientation of surgical practice.
Fast track surgery is a peri-operative management model, including different strategies to improve patients' convalescence, avoid metabolic alterations, reduce complications, and shorten hospital stay. Prerequisite is coordination between different practitioners (surgeon, anaesthetist, nurse, nutritionist, physiotherapist). The purpose of our investigation is to understand the level of fast track surgery application in Piedmont and to evidence analogies and differences among departments. ⋯ Influence of fast track surgery is significantly present in our territory, even though it is not fully concretized in protocols. The choice of fast track depends on the instruction, the environment and the sensibility of each surgeon. Knowledge of geographic distribution of departments applying this model can be useful to organize common protocols, starting from more experienced hospitals.

Many surgeons have attempted to reduce the number and the size of ports in laparoscopic cholecystectomy to decrease parietal trauma and pain, and to improve cosmetic results. We report a series of laparoscopic cholecystectomies using a single-port technique (SILS) through an umbilical incision in a pilot group of 21 cases. Our goal was to validate and develop the single-port access as a viable option. ⋯ We report our early difficulties and concerns about the procedure and propose solutions to the problems. Patients' request for improved cosmesis impels surgeons toward the application of SILS, but the true advantage of the technique should be assessed by more evidences. For this reason, we are planning a single-institution, prospective randomized controlled trial to compare postoperative pain, operating time and cosmetic result between one port and standard laparoscopic surgery.

Comparative Study
Comparison of ventilation and cardiovascular parameters between prone thoracoscopic and Ivor Lewis esophagectomy.
Thoracoscopic esophagectomy in the prone position is associated with better surgical ergonomics compared to the left lateral decubitus position due to the effects of gravity pooling blood outside the operative field and the reduced need for lung retraction. The aim of this study was to evaluate the physiological effects of prone thoracoscopic esophagectomy with single-lumen intubation on ventilation, respiratory gas exchange, and cardiovascular parameters. Thirty-two consecutive patients underwent esophagectomy either through a prone thoracoscopic approach or through a right thoracotomic approach. ⋯ Patients undergoing prone thoracoscopic esophagectomy showed higher oxygenation levels (p < 0.001), and a significantly lower mean pulmonary shunt fraction (p = 0.001). Perioperative hemodynamics remained stable throughout the surgical procedures. Thoracoscopic esophagectomy in the prone position with two-lung ventilation was associated with a significant improvement of global oxygen delivery and a significant reduction of the pulmonary shunt when compared to the Ivor Lewis operation.
