In particular, small bowel obstruction poses the most significant problem.[30] The use of surgical humidification therapy during laparoscopic surgery may minimise the incidence of adhesion formation.[32] Other techniques to reduce adhesion formation include the use of physical barriers such as films or gels, or broad-coverage fluid agents to separate tissues during healing following surgery.[30] Robotic laparoscopic surgery[edit] A laparoscopic robotic surgery machine.
