Although seroma is a frequent minor morbidity after TEP, it has no impact on postoperative recovery. Because all seromas invariably resolve, expectant treatment with observation is recommended. Inguinoscrotal hernia carries a four-fold increased risk of developing seroma after TEP.
The learning curve for unilateral TEP by a general surgeon peaked after performing 80 procedures. In most cases, unilateral TEP can be accomplished safely within 1 h. Even during the learning process, TEP carries a low morbidity and conversion rate.
Iliopubic vein and artery are universal findings in every patient. Both aberrant obturator artery and vein cross the superior pubic rami, and are therefore susceptible to injuries during dissection of the Bogros space and stapling of the mesh onto Cooper's ligament. Awareness of these aberrant vessels will help to reduce bleeding and subsequent morbidity. Tracing along the aberrant vessel can easily identify the obturator foramen, which is an anatomic landmark that indicates an adequate inferior dissection of the preperitoneal space.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
