Trans-Sylvian Resection of Giant Left Insular Glioma: Operative Technique and Nuances.

BACKGROUND: Insular glioma was considered a nonsurgical entity due to resection-associated morbidities. The advancement in neurosurgical techniques and adjuncts used in the last two decades made the resection of insular gliomas simpler for neurosurgeons with the maximum extent of resection and acceptable morbidity rates. The complex anatomy of this region remains a challenge for neurosurgeons and requires expertise. The key factors to achieve complete resection in the insular region are the thorough knowledge of surgical anatomy and meticulous microsurgical techniques. Intraoperative adjuncts such as image guidance along with cortical and subcortical mapping assist in excellent outcomes. OBJECTIVE: In this study, we describe the operative technique and application of trans-Sylvian approach to do the compartmental dissection done by the senior author, along with challenges faced, with the hope to highlight the efficacy of the approach to achieve maximal resection of this entity without compromising patient's safety. MATERIALS AND METHODS: A 32-year-old right-handed gentleman presented with episodes of excessive salivation, tingling sensation on the right side of the body along with nausea that lasted for 15-20 s for the last 8 months and one episode of speech arrest without any loss of consciousness and motor or sensory deficit. CEMRI of the brain was suggestive of left insular glioma. The patient underwent left pterional craniotomy, and gross total resection of the tumor was done using compartmental dissection. RESULTS: At follow-up after 1 month, the patient is seizure-free without any speech difficulty and motor or sensory deficit. CONCLUSION: Compartmental dissection of insular glioma is a safe and efficacious technique to achieve gross total resection of the tumor in this complex region without morbidity.

Prospective Nonrandomized Analytical Comparative Study of Clinicoradiological Relationship and Quality of Life between Lumbar Interbody Fusion and Posterolateral Lumbar Fusion.

STUDY DESIGN: This prospective, nonrandomized, analytic comparative study analyzed the outcome of 100 patients who underwent spinal fusion surgeries (Posterolateral fusion (PLF) and posterior lumbar interbody fusion [PLIF]) with 6 months of follow-up. OBJECTIVE: The aim of our study was to compare clinicoradiological outcome of the lumbar spinal fusion surgeries (PLF vs. PLIF/transforaminal lumbar interbody fusion [TLIF]), to assess the quality of life pre- and post-operatively in all patients, and to compare the results within the groups. SUMMARY OF BACKGROUND DATA: We retrieved the articles related to posterolateral fusion (PLF) and PLIF/TLIF through computer-assisted PubMed and Cochrane database search. Most of the studies in previous literature did not show any significant difference in the success of fusion between the two groups. However, the global outcome in terms of clinical and radiological parameters was good in all the studies. MATERIALS AND METHODS: Senior neurosurgeons who are part of the study treated 100 patients presented with degenerative disc disease (DDD). Patients underwent two types of spinal fusion surgeries: Posterolateral fusion (PLF) and PLIF/TLIF, and those two groups were compared for clinicoradiological outcome, successful fusion, and quality of life at 6 months of follow-up. Results were analyzed statistically using SPSS version 21.0 and presented in terms of frequency, percentage, mean, and standard deviation. Measurements were compared between groups using the Student's t-test (independent and paired) for normally distributed variables. Percentage was compared with Chi-square test in various parameters. Statistical significance was determined with P values; P < 0.05 was considered statistically significant. RESULTS: Patients aged between 30and 65 years with lumbar DDD who met the inclusion criteria were included in the study. Patients were operated for 1-3 vertebral levels and showed clinical satisfactory outcome on visual analog scale (P = 0.004) and modified-Oswestry low back pain disability questionnaire (Oswestry disability index) (P = 0.000) at 6 months as compared to the preoperative data, which was statistically significant. Radiological outcome in terms of lumbar lordotic angle (LLA, P = 0.000) and ratio of disc space height (DSH) and height of immediate superior vertebral body (P = 0.000) at 3 months of follow-up was also statistically significant. All of our patients showed a well-placed implant (screws and cage) in the follow-up period. Our patients showed successful fusion more in the PLIF group (81.25%) as compared to the PLF group (67.30%), but those results are not statistically significant (P = 0.112), and all of our patients showed statistically significant difference (P = 0.000) in quality of life score at 6 months of follow-up when compared with the preoperative score. CONCLUSIONS: We concluded from our study and after the review of literature that the patients with lumbar DDD should undergo spinal instrumentation surgery either PLF or PLIF as per the requirement as these surgeries provide good clinical and radiological outcomes in terms of pain, disability index, LLA, and maintenance of DSH. Although both the groups have few degrees of risks and complications, these are not major one and can be managed easily. The fusion rates are similar in both the groups (PLF and PLIF). Quality of life index showed significant difference within 1 week, after 3 months, and after 6 months of surgery in all of our patients.

Intracranial Chondroma of the Falx Cerebri: A Rare Case Report with Review of Literature.

Intracranial chondromas are extremely rare, benign slow-growing cartilaginous tumors mostly originating from embryonic rests at sphenoethmoidal region and sometimes can originate from the falx, convexity dura, the tentorium, the choroid plexus, or the brain parenchyma. In this article, we present a 22-year-old woman with a chondroma of dural origin. The clinical, radiological, and histopathological findings along with the operative findings and postoperative course are described as well as the pertinent literature regarding intracranial chondromas is reviewed.

Evaluation of Early versus Delayed Laparoscopic Cholecystectomy in Acute Cholecystitis.

Background. The role of early laparoscopic cholecystectomy for acute cholecystitis with cholelithiasis is not yet established. The aim of our prospective randomized study was to evaluate the safety and feasibility of early LC for acute cholecystitis and to compare the results with delayed LC. Methods. Between March 2007 to December 2008, 50 patients with diagnosis of acute cholecystitis were assigned randomly to early group, n = 25 (LC within 24 hrs of admission), and delayed group, n = 25 (initial conservative treatment followed by delayed LC, 6-8 weeks later). Results. We found in our study that the conversion rate in early LC and delayed LC was 16% and 8%, respectively, Operation time for early LC was 69.4 min versus 66.4 min for delayed LC, postoperative complications for early LC were 24% versus 8% for delayed LC, and blood loss was 159.6 mL early group versus 146.8 mL for delayed group. However early LC had significantly shorter hospital stay (4.1 days versus 8.6 days). Conclusions. Early LC for acute cholecystitis with cholelithiasis is safe and feasible, offering the additional benefit of shorter hospital stay. It should be offered to the patients with acute cholecystitis, provided that the surgery is performed within 96 hrs of acute symptoms by an experienced surgeon.
