CONTEXT: Laparoscopic techniques present a particular challenge to the academic surgeon in maintaining control and patient safety. The authors explored the use of verbal and physical control strategies including deixis, language used to locate subject in spatio-temporal, social and discoursal contexts, in this setting. METHODS: Forty cases of laparoscopic cholecystectomy at an academic centre were video and audio-recorded. Surgeon and trainee discourses and physical gestures during the crucial anatomical steps of the operation were qualitatively analysed using a hybrid inductive and deductive technique with explicit attention to the use of deixis...

BACKGROUND: Suturing with intracorporeal knot-tying is one of the five tasks of the Fundamentals of Laparoscopic Surgery (FLS), which is a pre-requisite for board certification in general surgery. This task involves placing a short suture through two marks in a penrose drain and then tying a double-throw knot followed by two single-throw knots using two needle graspers operated by both hands. A virtual basic laparoscopic skill trainer (VBLaST(©)) is being developed to represent the virtual versions of the FLS tasks, including automated, real time performance measurement and feedback...

While laparoscopic surgery has become increasingly widely used, many laparoscopic procedures are time-consuming and difficult to accomplish compared to open surgery. One such procedure is the ligation of endless organs. In this paper, the development and prototyping of a laparoscopic instrument that could significantly increase the efficiency of laparoscopic ligation is outlined. The mechanism is based on a snake-like flexible structure which is actuated by control wires. A simple simulation was carried out by both experienced surgical staff as well as non-surgical persons to confirm the effectiveness of the proposed mechanism...

REVIEW
Wesley W Ludwig, Michael A Gorin, Phillip M Pierorazio, Mohamad E Allaf
Robot assistance has been rapidly adopted by urological surgeons and has become particularly popular for oncological procedures involving the retroperitoneal space. The wide dissemination of robot assistance probably reflects the limited amount of operating space available within the retroperitoneum and the advantages provided by robot-assisted approaches, including 3D imaging, wristed instrumentation and the shorter learning curve compared with that associated with the equivalent laparoscopic techniques. Surgical procedures that have traditionally been performed using an open or laparoscopic approach, such as partial nephrectomy, radical nephrectomy, retroperitoneal lymph node dissection, nephroureterectomy and adrenalectomy, are now often being performed using robot assistance...
