- Laparoscopic Total Mesorectal Excision for Rectal Cancer after Neoadjuvant Treatment: Targeting Sphincter-Preserving Surgery(2011) ARAUJO, Sergio Eduardo Alonso; SEID, Victor Edmond; BERTONCINI, Alexandre; CAMPOS, Fabio Guilherme; SOUSA JUNIOR, Afonso; NAHAS, Sergio Carlos; CECCONELLO, IvanBackground/Aims: Laparoscopic total mesorectal excision for rectal cancer is under scrutiny. This study aimed at analyzing feasibility, adequacy of resection, impact on early outcomes after neoadjuvant chemoradiation therapy, and to investigate trend towards indication of laparoscopy for sphincter-preservation in a single university medical center. Methodology: Patients with distal rectal cancer submitted to neoadjuvant treatment followed by laparoscopic total mesorectal excision were prospectively enrolled. The studied parameters were: demographics, previous surgery, BMI, type of operation, rate of sphincter-preserving surgery, duration of surgery, conversion, specimen retrieval, lymphadenectomy, distal and radial margins, intra and postoperative morbidity, reoperations, hospital stay, and mortality. Results: From January 2000 to July 2010, 68 patients were enrolled. Mean age was 60 (30-87) years. There were 27 anterior and 41 abdominoperineal resections. Six patients underwent a totally laparoscopic resection and coloanal anastomosis. There was a trend (p=0.003) towards more sphincter-preserving surgery. Conversion was 4.5%. Intraoperative complication was 7.4%. Postoperative complications occurred in 15%. Mortality was 3%. Lymph-node harvest was 11 (0-33). Mean distal margin was 2.5cm (1-4). Radial margins were positive in 3 (10%) cases. Conclusions: Laparoscopic total mesorectal excision after neoadjuvant treatment is feasible and safe. Sphincter-preserving laparoscopic oncologic rectal surgery has been accomplished more frequently.

- Single-Session Baseline Virtual Reality Simulator Scores Predict Technical Performance for Laparoscopic Colectomy: A Study in the Swine Model(2014) ARAUJO, Sergio Eduardo Alonso; SEID, Victor E.; BERTONCINI, Alexandre B.; HORCEL, Lucas A.; NAHAS, Sergio C.; CECCONELLO, IvanOBJECTIVE: Virtual reality (VR) simulation helps reducing the learning curve of laparoscopic colectomy. Moreover, it may be used to ascertain surgeons' pretraining skills. It was aimed to establish predictive validity of specific parameters gathered during VR simulation training on sigmoid colectomy- and whether simulator parameters correlate with technical performance during the same operation in a swine model. DESIGN: Surgeons novice to laparoscopic colectomy underwent a single VR simulation session on sigmoid colectomy. Next, all participants performed a laparoscopic sigmoidectomy in the swine. Operations were recorded. Performance evaluation was conducted by 2 board-certified colorectal surgeons blinded to surgeons' simulator scores using an instrument specific to laparoscopic colectomy. For each participant, a mean score of specific skills was calculated. Linear regression analysis was used to identify simulator parameters that were best related to the score. The stepwise method was used to select parameters. The magnitude of the regression model was measured by the coefficient of determination (R-2) value. SETTING: The University of Sao Paulo Medical Center is a high-volume, public practice, university-affiliated hospital. PARTICIPANTS: A total of 14 first-year residents in digestive tract surgery were included. RESULTS: Analysis of variance demonstrated that the regression model was significant (p = 0.0001), and an association between simulation scores and specific skills was confirmed. The R2 value was 99%. The VR simulator parameters that strongly correlated with specific skills during laparoscopic colectomy in the swine were safe use of electrosurgery/energy device and safety of medial-to-lateral dissection. CONCLUSIONS: A single VR simulation session for novice surgeons in the sigmoid colectomy module generates baseline scores that highly correlated with performance of specific skills during a laparoscopic colectomy in the swine. This information may be useful in an attempt to tailor VR simulator practice according to a surgeon's needs.
