The benefits of laparoscopic ("minimally invasive" or "keyhole") surgery for gallbladder removal (cholecystectomy) over open surgical procedures in terms of significant reductions in pain, scarring and recovery time are well accepted. In a conventional laparoscopic cholecystectomy however, the excised gallbladder still has to be extracted through the abdominal wall skin via a laparoscopic port site using an incision of 10mm or greater. Despite being much smaller than that required for open surgery, this incision is painful, leaves a scar and can result in a port site hernia to follow requiring further surgery to repair it. Recent attempts to further reduce the invasiveness of the surgical procedure have suggested performing the operation via an endoscope passed through the mouth and through an incision in the stomach wall - so called Natural Orifice Translumenal Endoscopic Surgery (NOTES). Unlike a skin incision, an incision in the wall of the stomach (gastrotomy) should give no pain, visible scar or herniation risk yet still allow access to the peritoneal cavity for surgical procedures such as cholecystectomy. Against this, it has the potential risks of contamination and leakage of gastric contents into the peritoneal cavity. Whilst the limitations of present technology make it very difficult to perform an entire cholecystectomy through the stomach wall in patients, endoscopic methods for closing a gastrotomy are available that are approved for use in patients (CE marked) and it is hypothesised that removing the excised gallbladder through the stomach in this way would avoid the problems of extracting it through the abdominal wall described above. Data are required to determine whether the extraction of the gallbladder via a gastrotomy rather than through the skin is safe, producing smaller scars and a better cosmetic result. A secondary endpoint would be to assess possible reductions in pain and recovery from this less invasive approach.

Condition Intervention
Procedure: Recovery of gallbladder via gastrotomy instead of via the skin

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Safety and Feasibility Trial of Laparoscopic Small Port Cholecystectomy With Transgastric Gallbladder Recovery

Further study details as provided by Colchester Hospital University NHS Foundation Trust:

Primary Outcome Measures:
  • This is a pilot study aimed at examining the outcomes of gallbladder recovery through a gastrotomy, concentrating on safety. The main outcome is presence of surgical complications. [ Time Frame: 6 months ]

Secondary Outcome Measures:
  • Secondary outcomes include pain levels and cosmetic satisfaction [ Time Frame: 6 months ]

Enrollment: 0
Study Start Date: December 2009
Estimated Study Completion Date: March 2014
Estimated Primary Completion Date: March 2014 (Final data collection date for primary outcome measure)
Intervention Details:
    Procedure: Recovery of gallbladder via gastrotomy instead of via the skin
    The gallbladder is dissected as for a standard laparoscopic cholecystectomy but is then recovered via a hole in the stomach created and closed endoscopically rather than through the skin as in the standard fashion
