OBJECTIVETo analyze occurrence, prevention and treatment of the complications of thoracoscopic assisted spine surgery.

METHODSRetrospective review of 182 patients who underwent standard thoracoscopic technique or video-assisted thoracic surgical procedure from October 1998 to August 2004. The treatment of thoracic diseases included debridement, decompression with (or) reconstruction. The total number of complications were recorded, and its mechanism, prevention and treatment were analyzed.

RESULTSComplications occurred in 16 patients, 12 cases of perioperative complications included 3 patients suffered from pneumonia, 3 pulmonary atelectasis, 2 patients' lung injured by trocar, 1 patient obtained transient monoplegia, 2 suffered from transient intercostal nerve pain and 1 had superficial incision infection. Long-term complications occurred in 4 cases: spinal tuberculosis relapsed 2 cases (one who had diabetes obtained relapse in 8 months of post-operation and another relapsed with complex spinal tuberculosis in 4 weeks postoperation), 2 patients suffered from kyphosis deformity and pain.

CONCLUSIONSThe type and incidence of complications with thoracoscopic spine surgery mainly depend on indication, operation procedures and anesthesia, only by limit surgical indication, ameliorate technique, obey surgical principle and consummate perioperative treatment can we obtain mini-invasive effect by thoracoscopic assisted spine surgery.

BACKGROUND: A systematic literature review of interspinous dynamic stabilization, including DIAM, Wallis, Coflex, and X-STOP, was conducted to assess its safety and efficacy. METHODS: The search was done in Korean and English, by using eight domestic databases which included KoreaMed and international databases, such as Ovid Medline, Embase, and the Cochrane Library. A total of 306 articles were identified, but the animal studies, preclinical studies, and studies that reported the same results were excluded. As a result, a total of 286 articles were excluded and the remaining 20 were included in the final assessment. Two assessors independently extracted data from these articles using predetermined selection criteria. Qualities of the articles included were assessed using Scottish Intercollegiate Guidelines Network (SIGN). RESULTS: The complication rate of interspinous dynamic stabilization has been reported to be 0% to 32.3% in 3- to 41-month follow-up studies. The complication rate of combined interspinous dynamic stabilization and decompression treatment (32.3%) was greater than that of decompression alone (6.5%), but no complication that significantly affected treatment results was found. Interspinous dynamic stabilization produced slightly better clinical outcomes than conservative treatments for spinal stenosis. Good outcomes were also obtained in single-group studies. No significant difference in treatment outcomes was found, and the studies compared interspinous dynamic stabilization with decompression or fusion alone. CONCLUSIONS: No particular problem was found regarding the safety of the technique. Its clinical outcomes were similar to those of conventional techniques, and no additional clinical advantage could be attributed to interspinous dynamic stabilization. However, few studies have been conducted on the long-term efficacy of interspinous dynamic stabilization. Thus, the authors suggest further clinical studies be conducted to validate the theoretical advantages and clinical efficacy of this technique.

OBJECTIVEThe objective of this study is to review cerebrospinal fluid leakage (CSFL) after thoracic decompression and describe its regular and special features.

DATA SOURCESLiterature cited in this review was retrieved from PubMed and Medline and was primarily published during the last 10 years. "Cerebrospinal fluid", "leakage", "dural tears", and "thoracic decompression" were the indexed terms. Relevant citations in the retrieved articles were also screened to include more data.

STUDY SELECTIONAll retrieved literature was scrutinized, and four categories were recorded: incidence and risk factors, complications, treatment modalities, and prognosis.

RESULTSCSFL is much more frequent after thoracic decompression than after cervical and lumbar spinal surgeries. Its occurrence is related to many clinical factors, especially the presence of ossified ligaments and the adhesion of the dural sac. While its impact on the late neurological recovery is currently controversial, CSFL increases the risk of other perioperative complications, such as low intracranial pressure symptoms, infection, and vascular events. The combined use of primary repairs during the operation and conservative treatment postoperatively is generally effective for most CSFL cases, whereas lumbar drains and reoperations should be implemented as rescue options for refractory cases only.

CONCLUSIONSCSFL after thoracic decompression has not been specifically investigated, so the present study provides a systematic and comprehensive review of the issue. CSFL is a multi-factor-related complication, and pathological factors play a decisive role. The importance of CSFL is in its impact on the increased risk of other complications during the postoperative period. Methods to prevent these complications are in need. In addition, though the required treatment resources are not special for CSFL after thoracic decompression, most CSFL cases are conservatively curable, and surgeons should be aware of it.

OBJECTIVETo explore the surgical method and its effects of adjacent spinal segment degeneration after anterior cervical fusion.

METHODSFrom March 2000 to March 2011, 27 patients with spinal segment degeneration who had accepted the operation of anterior cervical fusion were treated with surgical treatment. There were 16 males and 11 females with an average age of 55.3 years (ranged from 48 to 72 years). JOA scores and image examination were used to evaluate the clinical effects.

RESULTSAll patients were followed up for 1.8 to 7.2 years with an average of 3.6 years. All pathological segments obtained fully decompression with good spinal bombe, no internal fixation loosening and cervical spine instability were found. Nerve root pain had disappeared and nerve function had significantly improved. Before operation, 3 days after operation and at last follow-up, JOA scores were 9.15 +/- 3.46, 13.96 +/- 2.79 and 13.52 +/- 2.91, respectively, and there was significant difference between preoperation and postoperation (P < 0.05). Intervertebral height and physiological curvature improved obviously than preoperation (P < 0.05).

CONCLUSIONIn order to relief spinal compression and rebuild spinal stability, a surgical treatment will be recommend to adjacent spinal segment degeneration combining spinal nerve symptoms and physical sign as soon as possible. Selecting an appropriate surgery to treat different compressed segment would receive satisfactory results.

OBJECTIVETo clinically characterize the divers who suffer from decompression sickness in group after diving, optimize therapeutic treatment settings for grouped patients where the conventional individualized treatment cannot be implemented.

METHODSClinical parameters of patients such as age, professional seniority in dive, labor intensity, diving depth and their symptoms were statistically categorized to identify the factors that correlate with treatment efficacy and recurrence rate. In accordance with the symptoms and the reactions to pressure, 4 treatment programs were applied: Program A, Program B, Program C, Program D.

RESULTS(1) age, professional seniority, diving depth, length of service, dive frequency were positively correlated with the treatment efficacy (P<0.05, P<0.01), and these parameters together with pain intensity were also positively correlated with recurrence risk (P<0.05, P<0.01), while long latency time of the disease often related with poor therapeutic outcome and high recurrence rate (P<0.01), (2) pain intensity were positively affected by age, diving depth and dive frequency (P<0.05, P<0.01), whereas negatively affected by disease latency time (P<0.01), (3) Four elements in this clinic project, selection of treatment program, length of service, diving depth and disease latency time of patient, were responsible for (or: could account for) 48.0% change of treatment efficacy, (4) Among Programs using different therapeutic pressure, Program D, C and B had better outcomes than Program A (P<0.01, P<0.05). Also, less patients in Program D, C and B suffered from recurrence with relative to Program A (P<0.01, P<0.05), (5) Between Programs adopting same hyperbaric pressure and treatment duration time, Program D was more efficient and fewer recurrent cases were found in it if compared to Program B (P<0.05), (6) In programs with same pressure and duration time settings, Program D was remarkably superior to program C in regard of its treatment efficacy.

CONCLUSIONSIn condition with only limited clinic supplies, Program D could be the first choice to provide the hyperbaric oxygen as an ideal group treatment, and it is not very necessary for the clinician to provide individualized therapy. An appropriate extension of stay in hyperbaric chamber may apply to some patients but depending on the clinical symptoms, however, no longer time than 120 min is recommended.

OBJECTIVETo analyze and summarize the characteristics and treatment of acute spinal cord decompression sickness. To explore the factors that influence the treatment effect.

METHODS77 cases of acute spinal cord decompression sickness patients should be divided into 4 groups according to the pressurized treatment and drug treatment options. They were group I, group II, group III and group IV. At the same time they were get hyperbaric oxygen therapy and other treatment. The evaluation index, were Frankel function classification and paraplegia index. There were 17 factors that affected the treatment effect.

RESULTSThe rate of early cure was 57.14% (44/77). The rate of late cure was 74.03% (57/77). Their difference was statistically significant (P<0.05). In 3 months and 1 year the cure rate of group IV and group B were the highest. But there was no difference between them(P>0.05). They were higher than group ii and group I (P<0.05). The Frankel function classification in 3months and 1 year in each group was higher than before treatment (P<0.05). The paraplegia index in 3 months and 1 year in each group was lower than before treatment (P<0.05). In 3 months and 1 year the Frankel function classification was increased gradually and the paraplegia index was decreased gradually in group I , group II, group III (P<0.05). In group IV and group III the Frankel function and the paraplegia index had not significant difference (P>0.05). Among the 17 factors that affect the treatment effect there are 9 factors that affect the proportion of the large.

CONCLUSIONSThe first choice of treatment method for the patients with acute spinal cord decompression sickness would be group III. Drug therapy was also imporpant. At the same time the hyperbaric oxygen therapy and other treatments were taken. Although the cure rate was not high in this article. But most of the cure is within 3 months. Within 1 year.the cure rate still could be improved. 9 factors that affect the efficacy of acute spinal cord decompression sickness was more noteworthy.

Pulmonary barotrauma is a kind of disease caused by the injury of lung tissue or blood vessel when the gas pressure of lung is too high or too lower than the external pressure of the body, which causes the air to enter the blood vessel and adjacent tissue. It could be happened in the escape of the divers with the light diving equipment or the sailors from submarine. Generally, the decompression chamber was used to treating the disease, and the minimum air pressure of 0.5 MPa recompression therapeutic schedule was used to selecting. In November 2019, a patient with pulmonary barotrauma combined with cerebral arterial gas embolism caused by improper underwater escape with light diving equipment was admitted to the General Hospital of Eastern War Zone. He was treated with 0.12 MPa oxygen inhalation recompression scheme in the oxygen chamber pressurized with air. 7 days later, the patient recovered and discharged.

Acute neurologic deterioration is not a rare event in the surgical decompression for thoracic spinal stenosis. We report a case of transient paraparesis after decompressive laminectomy in a 50-yr-old male patient with multi-level thoracic ossification of the ligamentum flavum and cervical ossification of the posterior longitudinal ligament. Decompressive laminectomy from T9 to T11 was performed without gross neurological improvement. Two weeks after the first operation, laminoplasty from C4 to C6 and additional decompressive laminectomies of T3, T4, T6, and T8 were performed. Paraparesis developed 3 hr after the second operation, which recovered spontaneously 5 hr thereafter. CT and MRI were immediately performed, but there were no corresponding lesions. Vascular compromise of the borderlines of the arterial supply by microthrombi might be responsible for the paraparesis.

OBJECTIVETo investigate the role of large decompressive craniectomy (LDC) in the management of severe and very severe traumatic brain injury (TBI) and compare it with routine decompressive craniectomy (RDC).

METHODSThe clinical data of 263 patients with severe TBI (GCS < or = 8) treated by either LDC or RDC in our department were studied retrospectively in this article. One hundred and thirty-five patients with severe TBI, including 54 patients with very severe TBI (GCS < or = 5), underwent LDC (LDC group). The other 128 patients with severe TBI, including 49 patients with very severe TBI, underwent RDC (RDC group). The treatment outcome and postoperative complications of the two treatment methods were compared and analyzed in a 6-month follow-up period.

RESULTSNinety-six patients (71.7 %) obtained satisfactory treatment outcome in the LDC group, while only 75 cases (58.6 %) obtained satisfactory outcome in the RDC group (P < 0.05). Moreover, the efficacy of LDC in treating very severe TBI was higher than that of RDC (63.0 % vs. 36.7 %, P < 0.01). The chance of reoperation due to refractory intracranial pressure (ICP) in the LDC group was significantly lower than that of the RDC group (P < 0.05), while the incidences of delayed intracranial hematoma and subdural effusion were significantly higher than those of the RDC group ( P < 0.05).

CONCLUSIONSLDC is superior to RDC in improving the treatment outcome of severe TBI, especially the very severe ones. LDC can also efficiently reduce the chances of reoperation due to refractory ICP. However, it increases the incidences of delayed intracranial hematoma and contralateral subdural effusion.
