From the Research
The optimal treatment of proctalgia fugax is typically salbutamol inhaler (option B). Proctalgia fugax is characterized by sudden, severe rectal pain that usually resolves spontaneously within minutes. Salbutamol, a beta-2 adrenergic agonist, works by relaxing the smooth muscle of the anal sphincter and pelvic floor, providing rapid relief during acute episodes, as supported by a study published in 1996 1. Patients can use 2 puffs of the inhaler when an attack occurs. This approach is preferred because it addresses the underlying mechanism of the condition, which involves spasm of the rectal muscles.
Other treatment options, such as amitriptyline, may be used for chronic pain conditions but are not first-line for the acute nature of proctalgia fugax. Puborectalis release is a surgical intervention that would be excessive for this self-limiting condition, while biofeedback therapy is more appropriate for chronic pelvic floor dysfunction rather than the acute episodes characteristic of proctalgia fugax. For patients with frequent episodes, preventive measures such as avoiding constipation and stress management techniques may also be beneficial. A more recent review from 2020 2 highlights the challenges in managing proctalgia fugax and the need for further investigation into treatment approaches, but it does not provide evidence to support a change from the recommended use of salbutamol inhaler for acute episodes.
Key points to consider in the management of proctalgia fugax include:
- The condition is self-limiting and often resolves without treatment.
- Salbutamol inhaler is the preferred treatment for acute episodes due to its ability to relax the anal sphincter and pelvic floor muscles.
- Other treatments, such as amitriptyline and biofeedback, may be considered for chronic pain or pelvic floor dysfunction but are not first-line for proctalgia fugax.
- Preventive measures, including avoiding constipation and managing stress, can help reduce the frequency of episodes.
