Background: Ambulatory surgery for anorectal procedures has become widely accepted. Recent reviews recommend a multimodal approach to pain management. However, these recommendations are largely based on single intervention studies. ⋯ Especially patients undergoing surgery for hemorrhoids or an anal fissure should receive adequate analgesia. Pain during defecation is problematic and finding a solution for this problem remains challenging. Further research into the combined use of different analgesic modalities is recommended.

Objective: Subcutaneous emphysema can be an alarming sign of a necrotizing soft tissue infection. However, non-infectious etiologies exist that can be treated conservatively. This case report describes a subcutaneous emphysema of unknown origin and highlights the importance of distinguishing these clinical entities. ⋯ Conclusion: The lack of apparent causes, the unexplained puncture marks and psychiatric comorbidity suggests the possibility of subcutaneous emphysema due to factitious manipulations. Patients with subcutaneous emphysema who remain clinically stable, have minimal pain and no significant inflammatory changes could be treated conservatively. Close clinical monitoring is essential to avoid delayed intervention in case of a necrotizing soft tissue infection.
