“…Wegen dieser technischen Herausforderungen wurde vorgeschlagen, dass sowohl patientenbezogene Kurzzeitvorteile sowie Kriterien einer adä quaten onkologischen Resektion (ausreichende adäquate Lymphadenektomie sowie distale und radiale Ränder) beeinträchtigt sein können, wenn wegen eines Rektumkarzinoms eine minimal-invasive Technik angewandt wird. Die Ergebnisse unserer Studie tragen zur wachsenden Literaturmenge bei, die aufzeigt, dass -in erfahrenen Händen -die MIS bei Rektumkarzinomen in der Tat die Kurzzeitergebnisse verbessern kann und im Vergleich mit der offenen Operation [13,14,15,16,17,18,19] vergleichbare onkologische Ergebnisse aufweist.…”

“…However, it has proven to be technically feasible and safe with no more or perhaps fewer complications than after open rectal surgery [35,36] . Low anterior resection (LAR) technically performed as laparoscopic TME or PME has the same oncological outcome when compared to traditional open rectal surgery [37][38][39][40] . For patients, laparoscopic surgery gives benefits regarding reduced postoperative pain, shortened postoperative ileus with faster bowel recovery after surgery, improved abdominal cosmesis, fewer wound infections, less postoperative small bowel obstruction and ventral hernias [41,42] .…”

Rectal cancer accounts for one third of all colorectal cancers. The age adjusted death rates from colorectal cancer have declined over recent decades due to a combination of colorectal cancer screening, improved diagnostic tests, improved standardized surgical technique, improved medical support, neoadjuvant chemotherapies and radiation treatment or combinations of these. Because of complex treatment algorithms, use of multidisciplinary teams in the management of rectal cancer patients has also been popularized. Medical gastroenterologists performing colonoscopies are frequently the first health care provider to raise the suspicion of a rectal cancer. Although the diagnosis depends on histological confirmation, the endoscopic presentation is almost diagnostic in many cases. In order to meet the patient's immediate needs for information, it is important that the endoscopist has knowledge about the investigations and treatment options that will be required for their patient. The aim of this paper is to describe the modern preoperative investigations and operative procedures commonly offered to rectal cancer patients taking into account perspectives of three colorectal surgeons, practicing in the USA, Europe and Asia.

“…Therefore, substantial experience and skill are required to perform laparoscopic surgery. [9][10][11] Surgical simulators are generally used to train surgeons in specific types of procedures without using animals or cadavers before working on live patients. [12][13][14] Although such surgical training systems enable surgeons to simulate surgery on the virtual organs of virtual or generic patients, it is impossible to perform patient-specific simulation, which needs to reproduce anatomical variations.…”

Abstract. Laparoscopic surgery, which is one minimally invasive surgical technique that is now widely performed, is done by making a working space (pneumoperitoneum) by infusing carbon dioxide (CO 2 ) gas into the abdominal cavity. A virtual pneumoperitoneum method that simulates the abdominal wall and viscera motion by the pneumoperitoneum based on mass-spring-damper models (MSDMs) with mechanical properties is proposed. Our proposed method simulates the pneumoperitoneum based on MSDMs and Newton's equations of motion. The parameters of MSDMs are determined by the anatomical knowledge of the mechanical properties of human tissues. Virtual CO 2 gas pressure is applied to the boundary surface of the abdominal cavity. The abdominal shapes after creation of the pneumoperitoneum are computed by solving the equations of motion. The mean position errors of our proposed method using 10 mmHg virtual gas pressure were 26.9 AE 5.9 mm, and the position error of the previous method proposed by Kitasaka et al. was 35.6 mm. The differences in the errors were statistically significant (p < 0.001, Student's t -test). The position error of the proposed method was reduced from 26.9 AE 5.9 to 23.4 AE 4.5 mm using 30 mmHg virtual gas pressure. The proposed method simulated abdominal wall motion by infused gas pressure and generated deformed volumetric images from a preoperative volumetric image. Our method predicted abdominal wall deformation by just giving the CO 2 gas pressure and the tissue properties. Measurement of the visceral displacement will be required to validate the visceral motion.
