Abstract
We have seen substantial changes in minimally invasive surgery since its development in the early 1900s. Over the past 10 years, the addition of natural orifice transluminal endoscopic surgery and robotics has turned our attention to improved cosmesis and advancements in instrumentation. We have developed a new technique-single port access (SPA) surgery-and have applied it to the cholecystectomy. In this paper, we present and review the application of this access technique to the first 5 consecutive patients that underwent an SPA cholecystectomy. All 5 patients were female, with an average age of 45 years and an average weight of 172 pounds. Indications included biliary dyskinesia and symptomatic cholelithiasis. Average operative time was 121 minutes in these initial 5 cases. All but 1 patient was discharged in 24 hours. At 6 months, no umbilical hernias were observed. This new technique allows for a complete cholecystectomy to be performed entirely through the umbilicus without the need for additional retraction sites or transabdominal sutures. This procedure utilizes the same basic technique of the laparoscopic cholecystectomy already employed by general surgeons. Therefore, the SPA cholecystectomy can be readily learned and performed by many surgeons without the need for expensive or experimental equipment. Using a single portal of entry to the abdominal cavity, the umbilicus, cosmesis, and scar reduction is achieved.
