Characteristics and Outcomes of Patients Undergoing Surgical Management of Hidradenitis Suppurativa: An ACS-NSQIP Data Analysis.

Objective: Hidradenitis suppurativa (HS) is a painful inflammatory skin disease. Management is largely medical, with surgery reserved for severe refractory cases. In this study, we sought to conduct a retrospective analysis of a multi-institutional surgical database to investigate the surgical management of patients with HS and identify trends in the postoperative outcomes. Approach: The 2011-2019 American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was reviewed to identify patients who underwent surgery for management of HS. Postoperative outcomes were assessed, including surgical and medical complications, length of hospital stay, reoperation, readmission, and nonhome discharge. This article was reported according to the STROBE criteria. Results: We identified 1,030 patients, of which 62% were female and 50% were black. The most common comorbidity was obesity (61%). Surgery was mainly performed by general surgeons (62%) and plastic surgeons (31%). Complications were overall low, with readmission being the most common (7.1%, unplanned 6.0%), followed by reoperation (5.8%). The most common surgical complication was superficial incisional infection (5.1%) and most common medical complication was sepsis (3.8%). Obesity is seen to affect surgical complication rates, with patients with obesity having higher rates of dehiscence (obese: 3.1% and nonobese: 1.0%; p  = 0.03) but lower rates of organ space infection (obese: 0.5% and nonobese: 2.0%; p  = 0.03) and transfusion (obese: 2.5% and nonobese: 5.2%; p  = 0.04). A focus on complications in patients undergoing flap reconstruction ( n  = 293; 23%), identified higher rates of surgical complications, with superficial incisional infection being the most common (flap reconstruction: 7.5% and incision and drainage, debridement, skin graft: 4.1%; p  = 0.04). Innovation: The surgical management of HS is analyzed at the national level, with postoperative complications seen to depend on race and obesity-status. Conclusions: Surgical management for HS is associated with low postoperative complications, making surgery a viable treatment option for this debilitating disease.
