A recent systematic review showed patients with hidradenitis suppurativa (HS) who underwent partial excision experienced higher rates of recurrence rates compared those who underwent wide excision.
While surgery is considered the best treatment for recurrent HS, there are varying reports of recurrence rates following surgery in the literature, the researchers noted. In the systemic review, they analyzed 125 articles that described partial excisions (n=33) and wide excisions (n=97).

The researchers found that the average estimated recurrence rates for partial excision and wide excision were 26% (95% CI 16% to 37%) and 5% (95% CI 3% to 9%), respectively. They also observed that the overall recurrence rate was significantly associated with female sex and HS caudal of the umbilicus.
“This systematic review showed higher recurrence rates when it was not intended to resect affected HS tissue with a radical margin,” the researchers concluded.
However, the quality of evidence was poor and reporting of results was mostly heterogeneous, they noted. “There is a need for more randomized controlled trials and uniformly reported treatment outcomes,” they added.
