Backgroud : Endoscopic cholecystectomy of patient with gall stone is a well known operative technique, which is performed by one surgeon, 1-2 operative assistants and 1 scrub nurse. Since the lacking of operative assistants, the new adjustable telescopic holder was invented to solve that problem.
Objective : To evaluate the efficacy of this new instrument by comparing the operating times and complication of the conventional endoscopic cholecystectomy with the endoscopic cholecystectomy using the new instrument .
Study design : Non – randomized clinical trial.
Setting : Department of Surgery, Chaiyaphum Provincial Hospital.
Subjects : Sixty patients with symptomatic gall stone, who were admitted at this hospital during November 2001 to may 2002. These patients were divided into two groups equally. Group I of patients were operated by the conventional endoscopic cholecystectomy, by a team of one surgeon, one operative assisitant, and one scrub nurse. Group II were operated similarly but susing the new adjustable telescopic holder in place of the assistant. Both groups were operated by the same surgeon. The operating time and complication were recorded.
Results : Thirty patients in group I were 6 males and 24 females, 15-78 years of age (average 52.8 years). Their body weights were 44-87 kilograms (average 67.5 kilograms). There were 2 patients who had diabetes mellitus and two had hypertension, and one patient with both diseases. Group II consisted of 5 males and 25 females, 17-76 years of age (average 52.5 years). Their body weights were 42 – 89 kilograms (average 65.8 kilograms). There were two cases with DM, one case with hypertension and one case with both diseases. The operating times of the group I and II were 24.6 ± 7.5 and 25.7 ± 8.9 minutes respectively (p> 0.05). There was no complication during and after operations. The price of the invented instrument was 50 times cheaper than imported instrument.
Conclusion : This new adjustable telescopic holder was effective and could replace the operating assistant in the endoscope cholecystectomy of patient with gall stone.
