Introduction: We conducted this study to identify the risk factors responsible for conversion from laparoscopic (L) to open (O) in our patients.
Methods and Procedures: We retrospectively analyzed the medical record files of all the patients who presented to our hospital with the diagnosis of colon carcinoma from Jan 2006 to Dec 2015 and underwent laparoscopic resection. Demographics, operative findings and histopathological reports were all recorded on a preformed data sheet. Risk factors responsible for conversion were identified and compared. All the analysis was performed on SPSS 20.
Results: In total 127 patients were operated laparoscopically. There were 19 conversions (15%). Increase BMI (21.7 for Lap Vs 25.3 for Open), male sex and tumor size (6cm for Lap Vs 7cm for Open) are significant risk factors that contributed to laparoscopic conversion rates. Age, pre-operative ASA and CEA levels were not significant risk factors. T4 disease was a significant risk factor for conversion (14.8% in lap and 31.6% in open group). Intra-operatively there was not much difference in two procedures in terms of blood loss (mean 50 mls for Lap Vs 100 mls for Open), duration of surgery (mean 227 minutes for Lap Vs 235 minutes for Open). Proximal, distal and mesenteric resection margins were comparable. Median number of lymph nodes retrieved were more in open group (average 22 for open Vs 16.5 for lap).
Conclusion: Tumor stage, tumor size, male sex and increased BMI were significant risk factors for conversion from laparoscopic to open colonic resections. Age, ASA status and CEA levels were not significant risk factors.
