Stapled hemorrhoidopexy was originally defined as a rectal mucosectomy. The aims of our retrospective, single-center study were to demonstrate if the excised specimen comprises only the mucosa or more wall rectal layers and if the latter excision should be considered a technical mistake with an increase in complications.   Materials and Methods:  We histopathologically analyzed surgical samples from patients who underwent stapled hemorrhoidopexy performed between 2014 and 2019. Patients were divided into three groups, according to the stapler used: Group A (single PPH®), Group B (double PPH®), and Group C (CPH34 HV™). We evaluated the actual wall layers included in the stapled rectal ring. For every specimen, we reconstructed the history of the corresponding patient and the incidence of complications.   Results:  Of the 137 histological slides available, 13 were only mucosectomies (9.5%), and 124 presented also the submucosa and muscularis propria (90.5%)−50/58 patients in Group A, 28/28 in Group B, and 46/51 in Group C. No statistically significant difference in the rate of complications was found when stratifying patients according to the thickness of the resection [mucosectomy (M) or “full thickness” (FT)].   Discussion:  Stapled hemorrhoidopexy is not a simple mucosectomy but a resection of the rectal wall with almost all its layers. This concept defines the entity of the surgical procedure and excludes a direct correlation with an increased rate of complications.
