Is the patient's reported loss of spontaneous libido, altered sense of identity, and changes in anal sensation and pressure after undergoing hemorrhoidectomy, fissurectomy, and sphincterotomy related to the surgeries or a separate condition?

Sexual Dysfunction and Altered Sensation Following Anorectal Surgery

The patient's loss of spontaneous libido, altered sense of identity, and changes in anal sensation after hemorrhoidectomy, fissurectomy, and sphincterotomy are likely directly related to the surgeries, particularly the sphincterotomy, which causes permanent changes in anal sphincter function and sensation that can profoundly impact sexual function and psychological well-being.

Direct Surgical Impact on Sensation and Function

The procedures performed—particularly lateral internal sphincterotomy—cause measurable and permanent alterations in anal sphincter function:

• Sphincterotomy permanently reduces internal anal sphincter tone, with resting anal pressure dropping from baseline (mean 138 mm Hg) to significantly lower levels (110 mm Hg at 12 months), though some recovery occurs over the first year 1
• This reduction in sphincter tone persists indefinitely, as the pressure remains significantly lower than preoperative baseline even after one year of healing 1
• The loss of pressure, tightness, and sensation the patient describes is an expected consequence of internal sphincter division, as the sphincter contributes to the anal "corpus cavernosum" function that is recognized as significant for continence and sensation 2
• Approximately 8.9-17.8% of patients develop de novo incontinence after these procedures, indicating substantial functional changes 3

Sexual Dysfunction as a Direct Consequence

The connection between anorectal surgery and sexual dysfunction is well-established in colorectal surgery literature:

• Sexual dysfunction occurs in 5-88% of men and approximately 50% of women following anorectal procedures, with wide variation depending on the extent of surgery 4
• The presence of a stoma independently predicts lower sexual function (β=-0.37, P=0.035), and while this patient doesn't have a stoma, the principle demonstrates how anorectal surgical changes directly impact sexuality 5
• Depressive symptoms (β=-0.09, P=0.001) and body image concerns significantly contribute to reduced quality of sexual life following colorectal procedures 5
• Fatigue (β=-0.02, P=0.034) independently predicts lower sexual function in patients after anorectal surgery 5

Loss of Spontaneous Libido: Biopsychosocial Mechanism

The patient's specific complaint about loss of spontaneous libido requiring forced rather than natural erotic thoughts represents a recognized pattern:

• Sexual desire disorder/decreased libido affects 23-64% of patients following procedures affecting the pelvic region, representing a spectrum from mild to severe 6
• The altered sense of identity and constant guarding the patient describes reflects body image disturbance, which is a documented predictor of reduced quality of sexual life (β coefficient significant at P<0.05) 5
• Psychological distress from altered bodily function creates a feedback loop where anxiety about sensation changes leads to hypervigilance ("constant guarding"), which further suppresses spontaneous sexual thoughts 5

Clinical Approach to This Patient

Assessment of Contributing Factors

Evaluate for reversible contributors to sexual dysfunction:

• Screen for depression and anxiety using validated instruments, as depressive symptoms are the strongest predictor of reduced quality of sexual life after anorectal procedures 5
• Assess for ongoing pain or discomfort during daily activities, as chronic pain suppresses libido through multiple mechanisms 6
• Evaluate the degree of functional impairment with validated incontinence scores (Vaizey score), as even minor incontinence profoundly affects self-image 3
• Determine if the patient has complete fissure healing, as persistent symptoms may indicate incomplete healing (fissurectomy has a 24.2% non-healing rate versus 2.2% for sphincterotomy alone) 3

Pharmacologic Interventions

For hypoactive sexual desire disorder in this context:

• Consider off-label bupropion 150-300 mg daily or buspirone 15-60 mg daily, which have shown benefit for low libido in non-cancer populations and may help restore spontaneous sexual thoughts 6
• Avoid phosphodiesterase-5 inhibitors as the primary issue is desire/libido rather than erectile function, and PDE5i do not address the central psychological component 6
• If depression screening is positive, prioritize antidepressant therapy with agents that have favorable sexual side effect profiles (bupropion, mirtazapine) rather than SSRIs which worsen sexual dysfunction 6

Psychological and Counseling Interventions

Refer for specialized psychosexual therapy or sexual counseling that specifically addresses:

• Body image concerns related to altered anal sensation and function 6
• Cognitive restructuring around the "altered sense of identity" the patient describes 5
• Techniques to reduce hypervigilance and "constant guarding" that prevents relaxation necessary for spontaneous libido 5
• This referral should be immediate and emphasized as primary treatment, as psychological factors are often more amenable to intervention than the permanent anatomical changes 6

Timeline and Expectations

Set realistic expectations about recovery:

• Sensation changes from sphincterotomy are permanent, with the internal sphincter showing gradual tone recovery over 12 months but never returning to baseline 1
• Sexual function and quality of sexual life follow different trajectories, with quality of sexual life often declining more than objective sexual function measures 5
• Maximum psychological adaptation typically requires 6-12 months with active intervention, though some patients continue to struggle with identity issues long-term 5

Critical Pitfalls to Avoid

• Do not dismiss the patient's concerns as purely psychological when there is clear anatomical basis for altered sensation—validation of the physical changes is essential before addressing psychological adaptation 2, 1
• Do not assume sexual function will spontaneously improve with time alone—active intervention is required, as quality of sexual life often worsens without treatment 5
• Do not overlook partner involvement—partner sexual function and quality of sexual life are predictive of patient outcomes (β=0.24 and β=0.30 respectively, P<0.001), suggesting couple-based interventions may be beneficial 5
• Recognize that "loss of spontaneous libido" is distinct from erectile dysfunction—treatments targeting arousal or performance will not address the central desire issue the patient describes 6
