Worldwide, primates, and humans increasingly share habitats and often enter in conflict when primates thrive in human-dominated environments, calling for special management measures. Reproductive control is increasingly used to manage population growth but very few monitoring data are available. Therefore, the efficiency and implications of such programs require a careful examination.

The LAPMAN (Medsys, Gembloux, BELGIUM) is a dynamic laparoscope holder guided by a joystick clipped onto the laparoscopic instruments under the index finger of the operator. It confers optimal control of the visual field while operating, ensures stable and smooth displacement of the laparoscope, and allows the operator to work in conditions of restricted surgical assistance, due to either unavailability of staff or economic constraints. It has been tested successfully in pilot studies in laparoscopic gynecologic surgery.

During laparoscopic surgery, the operator relies on the skills of an assistant, particularly during laparoscope manipulation. If possible, the surgeon would prefer to hold the scope while at the same time operating with both hands similar to open surgery conditions. A palm electronic interface (Lapman) was developed to allow remote control of a laparoscope manipulator and to make laparoscope displacement and instrument manipulation synchronous for the surgeon.
