OBJECTIVES: The aim of this study was to assess the results of laparoscopic surgery for @entity189 (LSRC) during the learning curve throughout the introduction of this technique at our medical center. MATERIALS AND METHODS: From January 2003 to April 2004, 40 @entity1 undergoing surgery were assigned to laparoscopic surgery group (LSG) (n=20) or conventional surgery group (CSG) (n=20). Data were prospectively collected to statistically analyze clinical, anatomopathological, and economic variables. RESULTS: Groups were comparable in age, sex, body mass index, American Society of Anesthesiologists score, surgical technique performed, @entity5 size and distance, Dukes' stage, and proportion of @entity1 with previous abdominal surgery and radiotherapy. There was no difference in operative time. LSG @entity190 was lower (p<.0001). LSG peristalsis and oral intake began earlier (p<.0001). LSG hospital stay was shorter (p<.0001). @entity3816 (10% LSG vs 15% CSG) and overall morbidity (35% LSG vs 45% CSG) were no different. LSG did not record any @entity834 . Two @entity1 (10%) were converted to open surgery. Regarding oncologic adequacy of resection, specimen length and number of nodes harvested were no different. LSG distal and radial resection margins were greater (p<.0001; p=.03). LSG operative costs were greater (p<.0001). However, CSG hospitalization costs were higher (p<.001). There was no overall difference (p=0.1). CONCLUSIONS: LSRC has been a reliable and efficient technique during the learning curve at our hospital.

A comparative clinical study of short-term results of laparoscopic surgery for XXXX during the learning curve.
