Do height and weight affect the feasibility of XXXX ?

@entity1 @entity9834
BACKGROUND: Laparoscopic cholecystectomy is the gold standard for gallbladder removal and the most common laparoscopic procedure worldwide. Single-incision laparoscopic surgery has recently emerged as a less invasive potential alternative to conventional three- or four-port laparoscopy. However, the feasibility of @entity9834 ( @entity9834 ) remains unclear, and there are no rigorous criteria in the literature. Identifying @entity1 at risk of failure of this new technique is essential. The aim of our study was to determine risk factors that may predict failure of the procedure. METHODS: From May 2010 to March 2012, 110 consecutive @entity1 underwent @entity9834 and were reviewed retrospectively. The main feasibility criterion was the procedure failure rate, defined as addition of supplementary port(s) and prolonged (>60  min) operative time. The factors evaluated were age, gender, height, weight, body mass index, previous abdominal surgery, indication for surgery and gallbladder suspension. RESULTS: There was conversion in 16 @entity1 (14.5  %), and the operative time exceeded 60  min for 20 @entity1 (30.9  %). Univariate analysis showed a significant independent association between additional port requirement and each of weight as a continuous value, weight >= 80  kg, BMI >26.5  kg/m(2) and height >172  cm. Univariate analysis also showed a significant independent association between prolonged operative duration (>60  min) and each of height and weight as continuous values, height >172  cm and previous abdominal surgery. In the multivariate analysis, only weight remained independently associated with additional port requirement, and height remained independently associated with prolonged operative duration. CONCLUSION: Preoperative identification of the factors increasing the risk of conversion may assist surgeons in making decisions concerning the management of @entity1 , including appropriate use of @entity9834 .
