Abstract
The objective of this thesis was to determine occurrence frequency and risk factors of laparoscopic entry-related complications with three different entry techniques. Medical records were reviewed for all dogs and cats that had carbon dioxide (CO2) insufflated laparoscopic surgery occurring between 2006 and 2018. Data including entry site, entry technique, signalment, body conformation, complications and operating surgeon/resident were analyzed by univariate regression analysis. Factors with p-values less than 0.25 were included in multivariate regression analysis. Complications occurred in 33/159 (21%) with 30/33 (91%) considered minor (CO2 leaks, omental insufflation, repeated entry). The Ternamian visual entry, modified Hasson, and Veress needle entry techniques had 7 (9%), 17 (26%), and 9 (60%) complications respectively. Major complications occurred in 3/159 (2%) where entry-related hemorrhage prompted conversion to an open technique (2 entries with Veress needle (13%), and 1 with the Ternamian visual (1%)). No mortality occurred. Univariate analysis identified species, entry technique, entry location, and time cohort as significant risk factors for entry-related complications. Entry location and entry technique remained significant in the final multivariate model. A Ternamian visual entry technique was associated with fewer complications than either the modified Hasson or Veress technique. In this single institution cohort, a Ternamian visual entry technique and midline entry site appeared associated with fewer complications than 2 other techniques. The findings in this study are preliminary and a possible superiority to any entry technique needs to be re-evaluated in a prospective randomized controlled study.
