[Manually assisted laparoscopic surgery--realistic evolution of the minimally invasive therapy concept? Initial experiences with the "Endohand"].

The essential limitations of laparoscopic procedures--lack of palpation, problematic retrieval of specimen and anastomosis, etc.--are abolished by the hand of the surgeon, which is inserted into the peritoneal cavity through a mini-laparotomy. While holding the pneumoperitoneum, the hand acts as an intelligent instrument performing surgical exploration, exposition of the field of operation, blunt dissection or intracorporal knot-tying. The mini-laparotomy is used to insert conventional instruments and suture material, as well as for specimen retrieval and anastomosis. Our preliminary experience (3x splenectomy, 2x sigmoid colectomy, 1x anterior resection of rectum, 1x proctocolectomy with J-pouch) shows that even extensive laparoscopic operations are accomplished much more simply. The time spent for such procedures is markedly reduced.
