Objective To explore the clinical effects of ileus tube in treatment of colonic obstruction caused by colorectal carcinoma. Methods Thirtytwo colorectal carcinoma patients with colonic obstruction admitted to our hospital from December 2005 to December 2008 were given onestage radical excision and anastomosis after transnasal or transanal placement of ileus tube for colonic decompression and drainage. Results Combined placement of transnasal and transanal ileus tube was successfully carried out in 19 cases, while the other 13 cases were treated only with transnasal ileus tube. Abdominal pain and distention of all cases were relieved 12-36 h after tube placement, while those of 26 cases disappeared 48-96 h later. Compared with before tube placement, abdominal circumferences of all cases were significantly reduced after tube placement, the mean reduction rate was (81.3±19.6)% vs. 100% (t=3.586, P=0.02). All cases were successfully treated by onestage radical excision and anastomosis 5-7 d after placement, and no serious complications such as peritoneal infection, anastomotic leakage etc. were found. Conclusion Preoperative intubation of ileus tube can enhance the therapeutic effects of onestage radical excision and anastomosis in patients with colorectal carcinoma combined with colonic obstruction.
Objective To investigate the treatment methods and the cl inical therapeutic effects of symptomatic cervical vertebral hemangioma associated with cervical spondylotic myelopathy. Methods A retrospective analysis was performed in 18 patients (10 males and 8 females, aged 30-62 years with an average age of 45.3 years) with cervical vertebral hemangioma associated with cervical spondylotic myelopathy between January 2006 and September 2008. The disease duration was 10-26 months (mean, 15.6 months). All patients had single vertebral hemangioma, including 2 cases at C3, 3 cases at C4, 5 cases at C5, 5 cases at C6, and 3 cases at C7. The X-ray films showed a typical “pal isade” change. According to the cl inical and imaging features, there were 13 cases of type II and 5 cases of type IV of cervical hemangioma. The standard anterior cervical decompression and fusion with internal fixation were performed and then percutaneous vertebroplasty (PVP) was used. The cervical X-ray films were taken to observe bone cement distribution and the internal fixation after operation. The recovery of neurological function and the neck pain rel ief were measured by Japanese Orthopaedic Association (JOA) score and visual analogue scale (VAS) score. Results All operations were successful with no spinal cord and nerves injury, and the incisions healed well. Anterior bone cement leakage occurred in 2 cases without any symptoms. All cases were followed up 24-28 months (mean, 26 months) and the symptoms were improved at different degrees without fracture and collapse of vertebra or recurrence of hemangioma. During the follow-up, there was no implant loosening, breakage and displacement, and the mean fusion time was 4 months (range, 3-4.5 months). The JOA score and VAS score had a significant recovery at 3 months and at last follow-up when compared with preoperative values (P lt; 0.05). Based on JOA score at last follow-up, the results were excellent in 9 cases, good in 6 cases, fair in 2 cases, and poor in 1 case. Conclusion The anterior cervical decompression and fusion with internalfixation combined with PVP treatment is one of the ideal ways to treat symptomatic cervical vertebral hemangioma associated with cervical spondylotic myelopathy, which could completely decompress the spinal cord and effectively alleviate the cl inical symptoms caused by vertebral hemangioma.
Objective To evaluate the effectiveness and safety of orbital decompression for compressive optic-neuropathy. Methods Fourteen eyes of twelve cases with Graves opthalmopathy and compressive optic-neuropathy undergone two orbital walls decompression with the follow-up period of more than 3 months were analyzed. Results The effect of complete closure of palpebral fissure was attained in all of the postoperative eyes and the visual acuity was increased in eleven eyes, remained no change in two eyes and decreased in one eye. The mean value of the recession of exophth almic eyes after operation was mean 4.0 mm. Conclusion Two or bital walls decompression is an effective method for compressive optic-neuropathy in Gaves ophthalmopathy. (Chin J Ocul Fundus Dis, 2001,17:303-304)
ObjectiveTo investigate the effect of non-heated silver needle decompression under the guidance of pathogenic principle of muscle shortening on patients with cervical vertebra disease of the nerve root type. MethodsSixty patients diagnosed with cervical vertebra disease of the nerve root type between April 2007 and June 2009 were divided randomly into therapy group (n=30), treated with non-heated silver needle decompression, and control group (n=30), treated with physical therapy. Then, we observed the total effective rate, positive physical signs and electrophysiological indexes of the patients 3, 6, 12, and 24 months after treatment. ResultsThe total effective rate was 96.7%, 93.3%, 93.3% and 86.7% in the therapy group 3, 6, 12, and 24 months after treatment, while it was 80.0%, 63.3%, 60.0%, and 50.0% in the control group, and the diTherence between the two groups in each time point was significant (P<0.05). The rate of positive sign in the top pressure test and Brachial plexus traction test lowered significantly 3, 6, and 12 months after treatment in both the two groups (P<0.05), while the rate lowered significantly only in the therapy group 2 years after treatment (P<0.05). Paraspinal tenderness lowered significantly at each time point in the therapy group after treatment (P<0.05), while the decrease in the control group had no significance (P<0.05). The interpeak latency of somatosensory evoked potential N9-N13 got significantly shorter at each time point after treatment in the therapy group (P<0.05), while this only happened at the time points of 3 and 6 months after treatment in the control group (P<0.05). The latency of wave F got significantly shorter at each time point after treatment in the therapy group (P<0.05), while the shortening only occurred 6 months after treatment in the control group (P<0.05). ConclusionNon-heated silver needle decompression under the guidance of pathogenic principle of muscle shortening is an effective treatment for patients with cervical vertebra disease of the nerve root type.
Objective To evaluate and compare the efficacy of anterior subcutaneous and submuscular transposition of the ulnar nerve in treating cubital tunnel syndrome. Methods From August 2006 to August 2008, 66 patients with cubital tunnel syndrome were treated with anterior subcutaneous transposition (subcutaneous group, 24 cases) and with anterior submuscular transposition (submuscular group, 42 cases). According to McGowan stages, all patients were at Stage2 or 3 entrapment neuropathy with paresthesia in the ring and small fingers. Respectively, 3 cases and 8 cases compl icated by interosseous muscle atrophy in subcutaneous group and in submuscular group. No significant difference was found in gender, age, duration of the disease, and compl ication between two groups (P lt; 0.05). The surgical features, distribution of Bishop rates, two-point discrimination test, muscular strength, and compl ications were recorded. Results The operation time was (28.4 ± 5.2) minutes in subcutaneous group and (43.8 ± 5.6) minutes in submuscular group, showing significant difference (P lt; 0.01). The incision length was (12.2 ± 2.5) cm in subcutaneous group and (13.6 ± 2.8) cm in submuscular group, showing significant difference (P lt; 0.05). All patients were followed up 1-3 years. According to Bishop scoring system, the results were excellent in 18 cases, good in 4 cases, and poor in 2 cases in subcutaneous group; excellent in 36 cases, good in 3 cases, and poor in 3 cases in submuscular group; and showing no significant difference between two groups (P gt; 0.05). At 6 months postoperatively, twopoint discrimination and grip strength were improved when compared with that of preoperation (P lt; 0.05), but there was no significant difference between two groups (P gt; 0.05). Pain and dysesthesia of the scar were noted in 1 patient of the subcutaneous group and 3 patients of the submuscular group. No infection or hematoma was found and no patient needed reoperation. Conclusion Both operative methods are effective alternative for treating cubital tunnel syndrome. The anterior ubcutaneous anterior transposition of the ulnar nerve has fewer traumas, and it is a better choice for some old patients.
Objective To assess the effectiveness of large-calibre (7.5#) transanal tube drainage and decompression on prevention from anastomotic leakage following anterior resection for rectal cancer. Methods Clinical data of 346 consecutive patients (M/F=1.39, age range 32-84 years, median age 58.5 years) undergone anterior resection for rectal cancer in this institute from January 2006 to December 2008 were analyzed retrospectively. Results The anastomotic leakage rate was 0 (0/185) and 5.59%(9/161) in patients with or without receiving large-calibre transanal tube drainage respectively. The anastomotic leakage rate was significantly decreased by large-calibre transanal tube drainage after anterior resection for rectal cancer (χ2=8.526, P=0.004). Eight cases of anastomotic leakage were treated conservatively and the other one required further surgical interventions. No perioperative death occurred in this series. Conclusion In this study, the large-calibre transanal tube drainage and decompression is effective in protecting rectal anastomosis and decreasing the rate of anastomotic leakage.
Objective To investigate the cl inical appl ication and efficacy of lumbar vertebral canal expansion withpreservation of posterior l igaments complex, and to study its biomechanical properties. Methods Eight fresh lumbosacralcadaveric samples were divided into 3 groups. In group A, 8 intact lumbosacral cadaveric samples were used for biomechanical test. In group B, L3-5 laminectomy were, after the test in group A, performed and the posterior l igaments complex was preserved. In group C, the posterior l iagments complex was excised after the test in group B. In all 3 groups, the axial compression test, three-point bending test and torsional test were conducted. From June 2000 to June 2006, 309 patients (152 males and 157 females, aged 20-80 years with the average of 57.2 ) with lumbar canal stenosis received operation of the lumbar vertebral canal expansion with preservation of posterior l igaments complex. The course of disease was 3 months to 41 years. There were 55 patients suffering from pure lumbar canal stenosis, and 254 from lumbar canal stenosis combined with lumbar disc herniation, among which 105 were at L4, 5 level, 56 at L4-S1 level, 86 at L5, S1 level, and 7 at L2, 3 level. The therapeutic effect was assessed based on the JOA low back pain scoring system, the satisfaction degree of patient and radiographical observation. Results The axial compression test was performed. In the position of forward bending, stress, strain and axial displacement were smaller in groups A, B than those in group C, and axial stiffness in groups A, B was higher than those in group C, and the difference was significant(P lt; 0.01). In the position of backward extension, there was no significant difference among 3 groups (P gt; 0.05). Concerning the three-point bending test, under the same bending moment, there was a significant difference in deflection, dip and bending rigidity between group A and group C, and also between group B and group C (P lt; 0.01), but no significant difference between group A and group B (P gt; 0.05). In the torsional test, under the same torsional angle, the torque in group B was bigger than that in group C (P lt; 0.01). Under the same torque, the torsional angle in group B was smaller than that in group C (P lt; 0.01), and the torsional stiffness in group B was higher than that in group C (P lt; 0.01). The compl ications included 7 cases of distraction of nerve root, 5 leakage of cerebrospinal fluid and 4 wound infection. All compl ications were treated and restored completely. All patients were followed up for 1-7 years. According to the JOA low back pain scoring system, the improvement rate averaged 86.0%. Of all the 309 cases, 163 were excellent, 112 good, 34 fair, and the choiceness rate was 89%. The satisfaction rate of patient was 87%. There was no radiographic vertebral instabil ity postoperatively. Conclusion The lumbar vertebral canal expansion with preservation of posterior l igaments complex is conducive to maintaining the stabil ity of lumbar spine and have good cl inical outcomes.
Objective To investigate the cl inical outcomes of lumbar spondylol isthesis associated with lumbar spinal stenosis through decompressive laminectomy, spondylol ithesis reduction system (SRS) internal fixation, single posteriolateralVigor Spacer threaded fusion cages and intertransverse process arthrodesis bone grafting. Methods From June 2002 to June 2006, 58 cases of lumbar spondylol isthesis were treated with decompressive laminectomy, fixed by SRS instrumentation, posterior installed with interbody Vigor Spacer Cage and bone grafted between intertransverse process arthrodesis. There were 47 males and 11 females, aged 32-66 years old (45.8 on average). The course of disease was 3 months to 7 years, with an medium course of 25 months. Accoding to the Meyerding standard, 38 cases were classified as degree I and 20 as degree II. Spondylol isthesis between L4 and L5 covered 21 cases and between L5 and S1 covered 37 cases. There were 44 cases of lumbar spondylol isthesis and 14 of degenerative lumbar spondylol isthesis. The intervertebral height was 1.5-10.5 mm with the average of 5.1 mm. Results All patients’ incisions obtained heal ing by first intension after operation. The operation time was 50-90 minutes with an average of 65 minutes. The blood loss was 200-500 mL with an average of 250 mL. The patients were followed up for 10-38 months with an average of 23.6 months. According to the Macrab criteria, 54 cases were excellent, 3 good, 1 fair and the choiceness rate was 98.3%. According to the Meyerding classification, 38 cases of degree I and 19 out of 20 cases of degree II obtained complete reduction, and the rate of complete reduction was 98.3%. There were 57 (98.3%) cases which fused well 3-6 months after operation. The intervertebral height resumed to 9.6-12.5 mm with an average of 11.6 mm, and no intervertebral height loss was found. Conclusion The treatment of lumbar spondylol isthesis with decompressive laminectomy, SRS internal fixation, single posteriorolateral Vigor Spacer threaded fusion cage and bone grafting has excellent cl inical results and stable reduction.
Objectives To systematically review the preventive effects of different pressure relief devices. Methods Databases including PubMed, The Cochrane Library, Web of Science, EMbase, CBM, CNKI, VIP and WanFang Data were searched to collect randomized control trials (RCTs) on the preventive effects of pressure relief devices for the surgical pressure sore from inception to December 2017. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Network meta-analysis was then performed using gemtc package of R 3.5.0 software, Stata 13.0 and JAGS 3.4.0 software. Results A total of 20 RCTs involving 4 183 patients were included. The network meta-analysis showed that micropulse dynamic pad was superior to standard pad. The gel pad was superior to sponge pad. The standard pad and cotton gauze pad. The foam dressing was superior to gel pad. All of the differences were statistically significant. The results of the ranking probability plot suggested foam dressing as an optimal resolution for preventing surgical pressure sore. Conclusions According to the network meta-analysis and rankings, foam dressing is superior to other decompression devices in preventing surgical pressure sores.
Objictive To evaluate the efficacy of decompression with and without fusion in the treatment of degenerative lumbar disease. Methods We searched the Cochrane Library (Issue 1, 2006), MEDLINE (1966 to April, 2006), EMBASE (1984 to April, 2006), the China Biological Medicine Database (to Dec., 2005), VIP (1989 to April, 2006) and hand-searched several related journals for randomized controlled trials (RCTs) and quasi-randomized controlled trials (quasi-RCTs) involving the comparison of the outcomes between decompression with and without fusion in the treatment of degenerative lumbar disease. The quality of the included trials was assessed. RevMan 4.2.8 software was used for statistical analysis. Results Seven studies involving 412 patients were included. The results of meta-analysis indicated that no statistically significant differences were observed between the two operative procedures in the cumulative clinical outcome (OR1.83, 95%CI 0.92, 3.41), incidence of postoperative leg pain (OR 1.04, 95%CI 0.48, 2.25), incidence of perioperative complications (OR 1.15, 95%CI 0.51, 2.60), incidence of re-operation (OR 0.68, 95%CI 0.30, 1.56) or pre and postoperative pain scores [Pre-op WMD 0.12, 95%CI (-0.44,0.68); Post-op WMD 0.08, 95%CI (-1.08,1.25)]. The only statistical significance was observed in the incidence of postoperative back pain (OR 0.25, 95%CI 0.14, 0.46). Four studies described the length of operation, the intraoperative blood loss, the duration of external fixation postoperative and the total cost in hospital, which revealed that decompression alone was superior to decompression plus fusion. Three studies described the relationships between the clinical outcome and the changes in segmental range of motion/disc height pre- and post-operatively, as well as the flexion-extension radiographs, which revealed that decompression plus fusion was superior to decompression alone. Conclusions There are no significant differences between the two procedures in clinical outcomes, incidences of postoperative leg pain, re-operation and complications. Decompression with fusion leads to fewer patients suffering from postoperative lumbago than that of decompression alone. There is insufficient evidence to demonstrate that the radiographs may predict the clinical outcomes. More high quality, large-scale randomized controlled trials are required.
