Trans-umbilical Single port appendectomy is a virtually scar-less newer technique of appendectomy. This study retrospectively compares it with the traditional multiport appendectomy in terms of the operative length, costs, complications, length of stay and post-operative pain.
Methods & Procedures:
Single port and multiport laparoscopic appendectomies done at our teaching institute were retrospectively analyzed for the time period of April 2009- September 2010. Institutional Review Board approved the study. Analysis of variance (ANOVA) was applied to measure the differences.
There were 45 single port appendectomies and 65 multiport laparoscopic appendectomies. Ruptured appendectomies had statistically significant higher costs, complications, operative length and length of stay than non-ruptured appendectomies as expected but there was no statistically significant difference in single vs. multiport ruptured cases. There were total 97 non-ruptured cases-39 single port and 58 multiport. The two techniques had comparable results in terms of the operative length, costs, complications, length of stay and post-operative pain in these groups. Single port appendectomies had less length of stay, less use of pain medications.
This study reports the largest adult single port appendectomy series in US. Single port appendectomy has the significant advantage of being the virtually scar-less appendectomy but this study also finds it comparable to the traditional multiport laparoscopic technique in terms of the operative length, costs, complications, length of stay and post-operative use of pain medication. BMI (Body Mass Index) was similar in two groups- indicating that higher BMI may not be a contraindication for single port cases. There was a trend towards less length of stay and less use of pain medications in the non-ruptured single port cases. Larger series is needed to support this trend.
