Endoscopic Lumbar Discectomy

Abstract Objective The paradigm of surgical therapy for spinal disease especially for lumbar disc herniation (LDH) has gradually shifted from the traditional open surgeries to minimal invasive spinal surgeries. Endoscopic discectomy has been performed widely using various devices and techniques. In this study we present our experience of endoscopic discectomy using a unique device with separate side-viewing channel. Methods Twenty-six patients with LDH treated between March 2015 and April 2018 using the unique conical working tube with separate side-viewing endoscopic channel have been retrospectively analyzed. Their preoperative and postoperative Oswestry Disability Index (ODI) and Macnab scores were used to evaluate the outcome with a mean follow-up of 37.04 months. Results There were 18 males and 8 females with age ranging from 19 to 72 years (mean, 38.4 years). The follow-up ranged from 25 to 60 months with mean of 37.04 months. The mean preoperative ODI score was 72.4, which decreased to a mean of 7.6 and the outcome evaluated by Macnab criteria was 65.3% excellent, 19.2% good, 11.5% fair, and 3.8% poor. One patient underwent second surgery. None of the patients had to change their occupation postoperatively. Complications that occurred were dural tear in one patient and transient foot paresis in one, which improved spontaneously. Conclusion Endoscopic discectomy using conical working tube is a safe and effective technique for lumbar disc prolapse. The long-term results are comparable to the conventional techniques.

Endoscopic Lumbar Discectomy

Background: Transforaminal endoscopic lumbar discectomy (TELD) is regarded as an effective treatment option for soft lumbar disc herniation (LDH). There have been few studies evaluating the long-term outcomes of endoscopic procedures compared with conventional surgery. Objectives: The objective of this study was to demonstrate the clinical outcomes of TELD compared with those of open lumbar microdiscectomy. Study Design: Between January 2009 and September 2011, 335 consecutive patients with symptomatic LDH were treated with decompressive discectomy, either TELD or open microdiscectomy. Patients were prospectively entered into the clinical database and their records were retrospectively reviewed. Setting: Hospital and outpatient surgical center. Methods: Data from 298 patients who were treated with decompressive discectomy, either TELD or open microdiscectomy, were evaluated with a minimum 5-year follow-up period. Among them, 146 patients were treated using TELD (TELD group), and the remaining 152 patients using open microdiscectomy (Open group). Perioperative data and clinical outcomes were evaluated using the visual analog scale (VAS), the Oswestry Disability Index (ODI), and the modified Macnab criteria. Results: The VAS and ODI significantly improved in both groups. The rate of excellent or good outcomes was 88.36% and 87.5% in the TELD and Open group, respectively. The reoperation rate was 4.2% and 3.3% in the TELD and Open group, respectively. There were no significant differences in the clinical outcomes; however, operative time, hospital stay, and time to return to work were significantly shorter in the TELD group (P < 0.01). Limitations: First, the patient selection was not randomized; therefore, the risk of bias might be increased. Second, this study lacks analysis of the radiographic changes related to the degenerative change over the long-term follow-up period. Conclusions: The long-term results of TELD for soft LDH are comparable to those of conventional open microdiscectomy. The selective endoscopic discectomy technique under local anesthesia provides the typical advantages of minimally invasive procedures such as a shorter operation time, hospital stay, and recovery time. Key words: Endoscopic, discectomy, hospital stay, lumbar disc, microscopic, operative time, return to work, transforaminal

Purpose: To evaluate a new self-expanding nitinol coil stent in stenotic or occluded peripheral arteries. Methods: Seventy-three symptomatic patients (58 men; mean age 67 years) were treated with nitinol stents for lesions in the iliac artery (9 stenoses); superficial femoral artery (SFA) (39 stenoses, 6 occlusions); popliteal artery and tibioperoneal trunk (9 stenoses, 7 occlusions); and 3 bypass grafts. Mean diameter stenosis was 84.4% ± 9.9% (range 75% to 100%), and mean lesion length was 45 ± 23 mm (range 20 to 120 mm). Results: Eighty-eight 40-mm-long stents with diameters between 5 and 8 mm were implanted percutaneously for suboptimal dilation (n = 45); dissection (n = 21); and restenosis (n = 7). All stents but one were implanted successfully; the malpositioned stent was removed, and another stent was successfully deployed. There were 3 (4.1%) failures due to thrombosis at 24 hours. During the mean 16-month follow-up (range to 44 months), 4 restenoses (3 femoral, 1 popliteal) have occurred; 2 were treated with repeat dilation and 2 underwent bypass. Primary and secondary patency rates at 18 months were 87% and 90%, respectively, for all lesions (iliac: 100% for both; femoral: 85% and 88%; popliteal: 87% and 100%). Conclusions: This new nitinol stent seems to be safe and effective with favorable long-term results, even in distal SFA lesions and popliteal arteries. Its flexibility and resistance to external compression allow its placement in tortuous arteries and near joints.

Operative Findings

Pulmonary artery sarcoma (PAS) is a rare and devastating disease. The diagnosis is often delayed, and optimal treatment remains unclear. The aim of this study is to report our experience in the surgical management of this disease. Between 2000 and 2018, 17 patients underwent operations for PAS at our center. The medical records were retrospectively reviewed to evaluate the clinical characteristics, operative findings, the postoperative outcomes, and the long-term results. The mean age at operation was 46.0 ± 12.4 years (range, 26–79 years), and eight (47.1%) patients were male. Six patients underwent tumor resection alone, whereas the other 11 patients received pulmonary endarterectomy (PEA). There were two perioperative deaths. Follow-up was completed for all patients with a mean duration of 23.5 ± 17.6 months (1–52 months). For all 17 patients, the median postoperative survival was 36 months, and estimated cumulative survival rates at 1, 2, 3, and 4 years were 60.0%, 51.4%, 42.9%, and 21.4%, respectively. The mean survival was 37.0 months after PEA and 14.6 months after tumor resection only ( p = 0.046). Patients who had no pulmonary hypertension (PH) postoperatively were associated with improved median survival (48 vs. 5 months, p = 0.023). In conclusion, PAS is often mistaken for chronic pulmonary thromboembolism. The prognosis of this very infrequent disease remains poor. Early detection is essential for prompt and best surgical approach, superior to tumor resection alone, and PEA surgery with PH relieved can provide better chance of survival.

Short Stems

In recent years, various uncemented proximal metaphyseal hip stems were introduced for younger patients as a bone preserving strategy. Initial osteodensitometric analyses of the surrounding bone of short stems indicate an increase of bone mass with secondary bone ingrowth fixation as a predictor of long-term survival of these types of implants. We report the outcome of 151 modular Metha short hip stem implants in 148 patients between March 2005 and October 2007. The mean follow-up was 5.8±0.7 years and the mean age of the patients was 55.7±9.8 years. Along with demographic data and co-morbidities, the Harris Hip Score (HHS), the Hip dysfunction and Osteoarthritis Outcome Score (HOOS), and also the results of a patient-administered questionnaire were recorded pre-operatively and at follow-up. The mean HHS increased from 46±17 pre-operatively to 90±5 the HOOS improved from 55±16 pre-operatively to 89±10 at the final follow-up. A total of three patients have been revised, two for subsidence with femoral revision and one for infection without femoral revision (Kaplan Meier survival estimate 98%). The radiological findings showed no radiolucent lines in any of the patients. The modular Metha short hip stem was implanted in younger patients, who reported an overall high level of satisfaction. The clinical and radiographic results give support to the principle of using short stems with metaphyseal anchorage. However, long-term results are necessary to confirm the success of this concept in the years to come.

The aim of our study was to review the long term clinical and radiological (MRI) outcomes of adult patients who underwent ACL reconstruction as children or adolescent with emphasize to the features of growth disturbance, angular deformity, meniscal and cartilage damage and revision rate We retrospectively evaluated patient who underwent ACL reconstruction in our clinic with arthroscopic transepiphyseal technique using hamstrings graft in childhood or adolescence between the years 1997 and 2009. A total of 43 Patients were assessed. 25 male and 18 female. The average age at time of surgery was 13,5 years (8 - 16 y.), at time of assessement 22,4 years (18 - 30 y.) . The mean follow up was 10 years (4 - 16 years). The physical development of the patients was assessed with the Lysholm score and the Cincinnati Knee score scale, their satisfaction was recorded on the basis of the IKDC subjective knee evaluation form and the Tegner activity score . Leg deformity or leg length discrepancy was evaluated clinically by the observers. The instrumented Lachman test using KT1000 and manual Pivot shift test was performed to assess knee stability. MRI was used to detect graft integrity, cartilage and meniscal damages. No significant leg deformities or leg length discrepancy had been detected. The average Lysholm score was 91 points (83 - 100), the Cincinnati Knee Score was 90,4 (79 - 100) points on average . The mean IKDC score was 92 points (82 -100). The Tegner-Activity-Score changed from preop 6,8 (2-10) to post op 5,8 (2-9). 2 Patient underwent revision ACL reconstruction due to rerupture (3 and 9 years post op). 2 Patients underwent meniscal surgery during follow up (1 resection and one refixation). KT1000 evaluation showed 67% excellent, 21% good and in 12% bad results. The MRI scan showed 42 intact grafts and one unverifiable graft. One patient with cartilage damage up to 3° (ICRS), 3 patients with meniscal degeneration up to grade 2. Each patient showed a free range of motion Our data underlines that transepiphyseal ACL reconstruction in children and adolescent with hamstrings is a save procedure leading to good long term results without causing angular deformity or growth disturbance

OBJECTIVE: Review long-term results of the modified cautery-assisted palatoplasty (mod CAPSO)/anterior palatoplasty for the treatment of mild-moderate obstructive sleep apnea (OSA). STUDY DESIGN: Prospective series of 77 patients. All patients were >18 years old, type I Fujita, body mass index (BMI) < 33, Friedman clinical stage II, with apnea-hypopnea index (AHI) from 1.0 to 30.0. The mean follow-up time was 33.5 months. The procedure involved an anterior soft palatal advancement technique with or without removal of the tonsils. The procedure was done under general or local anesthesia. RESULTS: There were 69 men and eight women; the mean age was 39.3 years old; and mean BMI was 24.9 (range 20.7–26.8). There were 38 snorers and 39 OSA patients. The AHI improved in patients with OSA, 25.3 ± 12.6 to 11.0 ± 9.9 ( P < 0.05). The overall success rate for this OSA group was 71.8 percent (at mean 33.5 months). The mean snore scores (visual analog score) improved from 8.4 to 2.5 (for all 77 patients). Lowest oxygen saturation also improved in all OSA patients. Subjectively, all patients felt less tired. CONCLUSION: This technique has been shown to be effective in the management of patients with snoring and mild-moderate OSA.

Object. Brachycephaly is a characteristic feature of Apert syndrome. Traditional techniques of cranioplasty often fail to produce an acceptable morphological outcome in patients with this condition. In 1996 a new surgical procedure called “dynamic cranioplasty for brachycephaly” (DCB) was reported. The purpose of the present study was to analyze perioperative data and morphological long-term results in patients with the cranial vault deformity of Apert syndrome who were treated with DCB. Methods. Twelve patients have undergone surgery performed using this technique since its introduction in 1991 (mean duration of follow-up review 60.2 months). Eleven patients had bicoronal synostosis and one had a combined bicoronal—bilambdoid synostosis. Perioperative data and long-term evolution of skull shape visualized on serial cephalometric radiographs were analyzed and compared with normative data. Changes in mean skull proportions were evaluated using a two-tailed paired-samples t-test, with differences being considered significant for probability values less than 0.01. The mean operative blood transfusion was 136% of estimated red cell mass (ERCM) and the mean postoperative transfusion was 48% of ERCM. The mean operative time was 218 minutes. The duration of stay in the intensive care unit averaged 1.7 days and the mean hospital stay was 11.8 days. There were no incidences of mortality and few complications. An improvement in skull shape was achieved in all cases, with a change in the mean cephalic index from a preoperative value of 90 to a postoperative value of 78 (p = 0.000254). Conclusions. Dynamic cranioplasty for brachycephaly is a safe procedure, yielding high-quality morphological results in the treatment of brachycephaly in patients with Apert syndrome.

Abstract BACKGROUND Glomus Jugulare tumors are benign but locally aggressive ones that represent a therapeutic challenge. Previous studies about the use of Gamma Knife Radiosurgery (GRS) in those tumors have documented good results that needed larger number of patients and longer follow up periods to be confirmed. MATERIAL AND METHODS Between August 2001 and December 2017, 70 patients with glomus jugulare tumors were treated at the Gamma Knife Center, Cairo. They were 46 females and 24 males. The mean age was 48 years (16–71 years). Nineteen of these patients were previously operated, 5 were partially embolized, 3 underwent embolization and subsequent surgery and 43 had gamma knife as their primary treatment. Volume-staged gamma knife radiosurgery was used in 10 patients and single-session in 60 patients, with a total of 86 sessions. The mean target volume was 12.7 cm3 (range 0.2 to 34.5 cm3). The mean tumor volume was 15.5 cm3 (range 0.2 to 105 cm3). The mean prescription dose was 14.5 Gy (range 12 to 18 Gy). RESULTS The mean follow up period was 60 months (range 18 to 206 months), and by the time of the data analysis, two of the patients were dead (66 and 24 months after GK treatment). The tumor control was 98.6% (69/70). Thirty-two tumors became smaller and 37 were unchanged. The symptoms improved in 36 patients, were stable in 32 patients, and worsened in 2 patients who developed a transient facial palsy and worsened hearing. Symptomatic improvement began before any reduction in tumor volume could be detected, where the mean time to clinical improvement was 7 months whereas the mean time to tumor shrinkage was 18 months. CONCLUSION This study about the long term follow up of the GKR for the intracranial glomus jugulare tumors confirmed that this is a highly effective and safe treatment. This data shows that the clinical improvement is not correlated with the radiological volume reduction.
