Following endoscopic transsphenoidal pituitary adenoma resection and tumor removal, patients are discharged home for recuperation. This recovery period may seem straightforward, yet it carries many critical precautions. Proper self-care enables smooth rehabilitation, while careless behavior may trigger severe complications.

1. Rest Arrangements

During the first month after discharge, the body gradually heals from surgical trauma, and physicians generally recommend one full month of rest. This does not mean strict bed rest without any movement; instead, patients must avoid heavy manual labor and strenuous exercise. As physical strength recovers, resume work gradually at a moderate pace, and refrain from immediately returning to pre-operative high-intensity workloads.

2. Exercise & Restricted Movements

Within one month postoperatively, patients must deliberately avoid the following actions: lifting heavy objects, forceful coughing, sneezing hard, straining during defecation, and forceful nose blowing. All these maneuvers cause abrupt spikes in intracranial pressure (ICP). The pituitary gland sits in a unique anatomical location, and the surgical site remains fragile during healing. Severe pressure fluctuations may tear incompletely healed tissue and even induce cerebrospinal fluid (CSF) rhinorrhea.

Maintaining unobstructed bowel movements is therefore vital during this phase. Increase dietary fiber intake, and use stool softeners if necessary.

3. Nasal Care — The Top Priority After Transsphenoidal Surgery

Blood-stained nasal discharge is normal within the first two weeks post-discharge, consisting of oozing from the surgical wound flowing through the nasal cavity, and requires no alarm. However, patients must seek urgent medical attention if clear watery fluid drips from the nose, with increased flow when bending forward and relief upon raising the head — this highly suggests CSF rhinorrhea.

CSF leakage elevates the risk of intracranial ascending infection and indicates incomplete skull base healing; prompt hospital revisit is mandatory without delay.

For patients without CSF leakage, nasal debridement under otorhinolaryngological endoscopy is recommended around postoperative week 2. Surgeons use endoscopes to clear intranasal hematoma and crusts, significantly accelerating olfactory recovery and improving overall comfort. Do not delay this procedure, as retained clots and crusts hinder wound healing.

No strict dietary restrictions apply, and most foods are permitted. One key rule must be observed: limit total daily fluid intake to 1,500–2,000 mL within the first two weeks after surgery. Pituitary manipulation inevitably disrupts antidiuretic hormone secretion. Excessive fluid intake unbalanced by hormone levels disturbs electrolyte homeostasis, resulting in hyponatremia.

Mild hyponatremia manifests as fatigue and poor appetite; severe cases progress to confusion and seizures. Seek emergency electrolyte testing immediately once these symptoms emerge.

4. Central Diabetes Insipidus (DI)

This is one of the most concerning postoperative complications, though its actual incidence remains low. Classic clinical manifestations include unrelenting thirst, excessive fluid intake, and marked polyuria: frequent daytime urination (over ten times daily), multiple nighttime awakenings to void, and total 24-hour urine output easily exceeding 3,000 mL.

Do not panic if this occurs. Oral desmopressin (DDAVP) prescribed by clinicians effectively reduces urine volume. Postoperative DI is mostly transient for pituitary adenoma patients, resolving spontaneously within 1–3 weeks for the majority; only a tiny minority develop chronic DI requiring long-term management.

Summary of Key Postoperative Guidelines

• Adequate rest for one month, maintain smooth bowel movements, and avoid all ICP-raising maneuvers;

• Closely monitor nasal discharge for clear watery CSF leakage;

• Schedule endoscopic nasal debridement two weeks after surgery;

• Avoid unrestricted fluid consumption;

• Do not endure persistent polyuria and polydipsia — seek medical care promptly.

• Strict adherence to the above measures ensures a smooth recovery phase, laying a solid foundation for subsequent scheduled follow-up imaging and adjuvant therapy.
