OBJECTIVE Early discharge following uncomplicated endonasal resection of pituitary adenoma has been described as safe and feasible. Discharge on postoperative day (POD) 1 is not a widely implemented practice in the United States. This study aimed to evaluate the safety of routine POD1 discharges by assessing postoperative unplanned medical care rates compared with those of patients discharged on POD 2 or later (POD2+). The secondary endpoint was to identify predictors of delayed discharge in the POD2+ cohort. METHODS A retrospective database review of the medical records of 534 patients who underwent endonasal resection of pituitary adenoma at the Mayo Clinic was performed. Relevant demographics, tumor characteristics, and perioperative metrics were abstracted from the medical record, including intraoperative CSF leakage, postoperative complications, emergency department visits, or inpatient readmissions within 30 days. Descriptive, univariate, and multivariate analyses were performed. RESULTS In comparison to 422 (79%) patients discharged on POD1, 112 (21%) patients discharged on POD2+ had a higher unplanned medical care rate (13% vs 5.5%, p = 0.019). There were significantly more men in the POD1 group (48%) than in the POD2+ group (37%) (p < 0.04). The most common reasons for POD1 unplanned care were endocrine dysfunction (2.4%), split evenly between syndrome of inappropriate antidiuretic hormone and adrenal insufficiency, whereas the most frequent reason in the POD2+ cohort was medical (0.06%). Univariate analyses indicated that female sex, higher BMI, intensive care unit (ICU) admission, obstructive sleep apnea, continuous positive airway pressure dependence, intraoperative CSF leakage, and diabetes insipidus (DI) increased the likelihood of POD2+ discharge. The reduced logistic regression model demonstrated a higher likelihood of POD2+ discharge with older age, ICU admission, intraoperative CSF leakage, and DI (p < 0.001). Common factors contributing to discharge after POD1 included endocrine (n = 66, 35%) and/or medical (n = 65, 34%) reasons. CONCLUSIONS Routine patient discharge on POD1 following uncomplicated endonasal resection of pituitary adenoma is a safe practice, as evidenced by the significantly lower rates of unplanned medical care and complications compared with those of patients discharged on POD2 or later. Delayed discharge was associated with older age, ICU admission, intraoperative CSF leakage, and DI. The most frequent reasons for POD1 readmission were endocrine versus medical reasons for POD2+. Preoperative identification of risk factors for delayed discharge and preemptive management of endocrine and medical complications may reduce the length of stay and return to medical care.

OBJECTIVE Petroclival meningiomas (PCMs) are challenging lesions to treat because of their deep location and proximity to critical neurovascular structures. Patients with these lesions commonly present because of local mass effect. A symptom that proves challenging to definitively manage is trigeminal neuralgia (TN), which occurs in approximately 5% of PCM cases. To date, there is no consensus on whether microsurgical resection or stereotactic radiosurgery (SRS) leads to better outcomes in the treatment of TN secondary to PCM. In this systematic review and meta-analysis, the authors aimed to evaluate the available literature on the efficacy of microsurgical resection versus SRS for controlling TN secondary to PCM. METHODS The Embase, MEDLINE, Scopus, and Cochrane databases were queried from database inception to May 17, 2022, using the search terms “(petroclival AND meningioma) AND (trigeminal AND neuralgia).” Study inclusion criteria were as follows: 1) reports on patients aged ≥ 18 years and diagnosed with TN secondary to PCM, 2) cases treated with microsurgical resection or SRS, 3) cases with at least one posttreatment follow-up report of TN pain, 4) cases with at least one outcome of tumor control, and 5) publications describing randomized controlled trials, comparative or single-arm observational studies, case reports, or case series. Exclusion criteria were 1) literature reviews, technical notes, conference abstracts, or autopsy reports; 2) publications that did not clearly differentiate data on patients with PCMs from data on patients with different tumors or with meningiomas in different locations (other intracranial or spinal meningiomas); 3) publications that contained insufficient data on treatments and outcomes; and 4) publications not written in the English language. References of eligible studies were screened to retrieve additional relevant studies. Data on pain and tumor outcomes were compared between the microsurgical resection and SRS treatment groups. The DerSimonian-Laird random-effects model with Hartung-Knapp-Sidik-Jonkman variance correction was used to pool estimates from the included studies. RESULTS Two comparative observational studies and 6 single-arm observational studies describing outcomes after primary intervention were included in the analyses (138 patients). Fifty-seven patients underwent microsurgical resection and 81 underwent SRS for the management of TN secondary to PCM. By the last follow-up (mean 71 months, range 24–149 months), the resection group had significantly higher rates of pain resolution than the SRS group (82%, 95% CI 50%–100% vs 31%, 95% CI 18%–45%, respectively; p = 0.004). There was also a significantly longer median time to tumor recurrence following resection (43.75 vs 16.7 months, p < 0.01). The resection group showed lower rates of pain persistence (0%, 95% CI 0%–6% vs 25%, 95% CI 13%–39%, p = 0.001) and pain exacerbation (0% vs 12%, 95% CI 3%–23%, p = 0.001). The most common postintervention Barrow Neurological Institute pain score in the surgical group was I (66.7%) compared with III (27.2%) in the SRS group. Surgical reintervention was less frequently required following primary resection (1.8%, 95% CI 0%–37% vs 19%, 95% CI 1%–48%, p < 0.01). CONCLUSIONS Microsurgical resection is associated with higher rates of TN pain resolution and lower rates of pain persistence and exacerbation than SRS in the treatment of PCM. SRS with further TN management is a viable alternative in patients who are not good candidates for microsurgical resection.
