Efficacy of routine post-operative head computed tomography on cranial surgery patients outcome.

OBJECTIVE: To identify the role of routine postoperative head CT in changing postoperative management after elective craniotomies. METHODS: We conducted a retrospective study on adult patients who underwent cranial surgery. Exclusion criteria includes cranial CTs done postoperatively for urgent clinical indications, pediatric patients, CSF diversion procedures and sedated patients. Patients were placed into "positive" group if the physical assessment changed from the baseline in the form of clinical deterioration, and the "negative" group if the exam did not change. The data then were analyzed to identify which patients needed further medical or surgical management based on CT findings only with "negative" physical examination. RESULTS: Total of 222 were included in the study. 151 patients had negative physical examination. Only 8 out of 151 patients had positive CT findings. Two patients out of 222 (0.9%) had a negative physical exam and positive CT findings that required additional action that wouldn`t be done urgently without routine postoperative brain CT. Only one patient out of 222 (0.4%) who was re-operated urgently based CT findings only and negative physical examination. CONCLUSION: Routine postoperative routine brain CT did not alter the course of medical management, even in the presence of significant radiological findings.

Supratentorial Craniotomies with or without Dural Closure-A Comparison.

BACKGROUND: Dural closure is a routine surgical step in neurosurgery. The benefit of suturing the dura to achieve watertight closure-with or without the use of dural substitutes-has been questioned in supratentorial craniotomy. We performed a retrospective study to examine the possible benefits and harms of suturing the dura compared with no dural closure and the occurrence of postoperative infection, cerebrospinal fluid (CSF) leak, and postcraniotomy headaches. METHODS: We performed a retrospective study to compare the incidence of CSF leak, infection, surgical site swelling, and postcraniotomy headaches between patients with watertight dural closure (closed group) and patients without watertight dural closure (open group). Any method used to close the dura and to achieve watertight closure was included, whether primary or secondary closure (with or without using suturable dural substitute). RESULTS: Overall, 216 patients were included in the present study, with 112 patients in the open group and 114 in the closed group. The open group experienced a greater incidence of infection and CSF leak (6 in the open group vs. 2 in the closed group), but without statistical significance (P = 0.15). We found no difference in surgical site swelling (P = 0.29). However, the closed group showed a greater association with the development of postcraniotomy headaches (P = 0.001). CONCLUSION: We found no difference in the occurrence of CSF leak, infection, or surgical site swelling between the closed and open groups. The incidence of postcraniotomy headaches was greater in the closed group, and the difference was statistically significant.
