Objective To discuss the key issues in the diagnosis and treatment of degenerative disc disease and thetherapeutic effect of transforaminal lumbar interbody fusion on it. Methods From September 2004 to August 2006, 15 cases of degenerative disc disease were treated by transforaminal lumbar interbody fusion, including 8 males and 7 females with the age of 33-46 years. All cases were single-level degenerative disc diseases, including 1 case of L3,4, 8 cases of L4,5 and 6 cases of L5, S1. The course of the disease was 2 -10 years. Preoperatively, the score of visual analogue scale (VAS) was 8.9 ± 1.8 and the score of Oswestry disabil ity index (ODI) was 51.4 ± 8.3. All patients had received normal conventional treatment for at least 3 months and had no therapeutic effect before operation. Results The operation time was 120-180 minutes (150 minutes on average) and the intra-operative blood loss was 200-500 mL (360 mL on average). There was no severe compl ication, except that the muscle tone of anterior tibia in one case decreased to the third level, which recovered to the 5- level 3 months after operation. A total of 15 cases were followed up for 12-24 months (18 months on average). All patients got interbody bony fusion 12 months after operation with the fusion rate of 100%. Postoperatively, the score of VAS was 2.8 ± 1.6 and the score of ODI was 19.1 ± 3.2, indicating there were significant difference in comparison with postoperative ones (P lt; 0.05). The improvement rates of postoperative VAS and ODI were 61.8% ± 7.3% and 64.3% ± 5.5%, respectively. For the therapeutic effect, 6 cases were regardedas excellent, 8 good, 1 fair, and the choiceness rate was 93.3%. All patients resumed their jobs and normal l ives. Conclusion Transforaminal lumbar interbody fusion is effective for the treatment of lumbar degenerative disc disease, but the indications for operation must be strictly defined.
ObjectiveTo evaluate the safety and efficacy of unconventional abdominal drainage after laparoscopic hepatectomy.MethodsThe clinicopathologic data of patients who underwent laparoscopic hepatectomy for liver tumors in the Mianyang Central Hospital from June to December 2019 and met the inclusion criteria were retrospectively collected. Based on whether drainage tube was placed in the abdominal cavity during operation, the patients were divided into non-catheterized group (without drainage tube) and catheterized group (with drainage tube). The intraoperative data and postoperative complications (e.g. intraabdominal hemorrhage, bile leakage, abdominal infection, and liver failure) were compared between the two groups. Then, the intraoperative data and postoperative conditions of liver cancer and non-liver cancer patients with or without abdominal drainage tube were compared and analyzed.ResultsA total of 117 eligible patients were included in the study. The non-catheterized group had 59 patients and the catheterized group had 58 patients. The patients with liver cancer had 84 patients (44 non-catheterized patients and 40 catheterized patients) and the patients without liver cancer had 33 patients (15 non-catheterized patients and 18 catheterized patients). ① On the whole, the groups were comparable in the baseline data between the non-catheterized group and the catheterized group, such as gender, age, HBV infection, body mass index, hepatic function index, liver stiffness value, disease category, etc. (P>0.05). Compared with the catheterized group, the non-catheterized group had earlier off-bed activities and earlier flatus time (P<0.001), and shorter postoperative hospital stay (P=0.030). However, no statistically significant differences were found in other indicators between the two groups (P>0.05). ② Whether the patients had liver cancer or not, the non-catheterized patients still had earlier off-bed activities and earlier flatus time as compared with the catheterized patients (P<0.001). Among the patients with liver cancer, no difference was found in postoperative hospital stay. However, among the patients without liver cancer, the non-catheterized patients had shorter postoperative hospital stay than the catheterized patients (P=0.042). No statistically significant differences were found in other indicators between the catheterized patients and non-catheterized patients (P>0.05).ConclusionFor technologically skilled laparoscopic hepatectomy center, selectively not placing peritoneal drainage tube after surgery might better promote the health of patients.
【Abstract】 Objective To investigate the effectiveness of surgical treatment for discogenic low back pain (DLBP) by minimally invasive transforaminal lumbar interbody fusion (TLIF) combined with unilateral pedicle screw fixation (UPSF). Methods Between March 2006 and July 2009, 57 patients with single-level DLBP were treated by minimally invasive TLIF combined with UPSF, including 27 males and 30 females with an average age of 45.6 years (range, 38-61 years) and a disease duration of 3.8 years (range, 9 months to 11 years). The involved segments included L2，3 in 2 cases, L3，4 in 5 cases, L4，5 in 29 cases, and L5, S1 in 21 cases. The operative time, incision length, intraoperative blood loss, postoperative drainage volume, hospitalization times, fusion rate, and complications were observed. The effectiveness were evaluated through Oswestry disability index (ODI) and visual analogue score (VAS), and the operative outcomes were compared in different groups classified according to various pressures of the contrast medium and sensitivities to discoblock after inducing consistent pain. Results The operation time, incision length, blood loss, postoperative drainage volume, and hospitalization times were (84.6 ± 37.4) minutes, (3.4 ± 0.6) cm, (132.5 ± 23.2) mL, (58.7 ± 21.4) mL, and (6.5 ± 0.8) days, respectively. All patients were followed up 2 years and 2 months to 5 years and 4 months (mean, 3.2 years). At last follow-up, ODI and VAS scores were significantly improved when compared with preoperative scores (P lt; 0.05). The effectiveness according to ODI were excellent in 27 cases, good in 22 cases, fair in 6 cases, and poor in 2 cases, with an excellent and good rate of 86.0%. All patients acquired b interbody fusion. At last follow-up according to ODI and VAS scores, better results were found in patients of low-pressure sensitive group and high-sensitive discoblock group (P lt; 0.05). Conclusion Minimally invasive TLIF combined with UPSF is reliable for DLBP with minimal surgical trauma, less paravertebral tissue injury, and fewer complications, but the indications for operation must be strictly followed. Patients being sensitive to low-pressure or high-sensitive to discoblock can achieve better surgical results.
Objective To investigate the effectiveness of surgical treatment for single-level degenerative lumbar instabil ity (DLI) by comparing traditional open transforaminal lumbar interbody fusion (TLIF) with minimally invasive TLIF. Methods Between March 2007 and May 2009，87 patients with single-level DLI were treated by traditional open TLIF (group A, n=45) and by minimally invasive TLIF (group B, n=42), respectively. There was no significant difference in gender, age, disease duration, segment level, combined diseases of lumbar spine, or the proportion of uni- and bilateral symptom between 2groups (P gt; 0.05). The indexes of surgical trauma，systemic inflammatory response, cl inical outcomes, and aravertebral muscle injury were compared between 2 groups. Results Operation was performed successfully in all patients. The patients were followed up 2.9 years on average in group A and 2.8 years on average in group B. The incision, blood loss, and postoperative drainage in group B were significantly less than those in group A (P lt; 0.05), but the operation time in group B was significantly longer than that in group A (P lt; 0.05). There were significant differences (P lt; 0.05) in C-reactive protein, leucocyte count, and creatine kinase MM between 2 groups at 24 hours postoperatively as well as in C-reactive protein at 6 days postoperatively; group B was superior to group A. At last follow-up, the Oswestry disabil ity index (ODI) and visual analogue score (VAS) were significantly improved when compared with the preoperative scores in 2 groups (P lt; 0.05). There were significant differences in ODI and back pain VAS score (P lt; 0.05), but no significant difference in leg pain VAS score (P gt; 0.05) between 2 groups. At last follow-up, no low back pain occurred in 8 and 18 cases, mild in 25 and 18 cases, moderate in 9 and 6 cases, and severe in 3 and 0 cases in groups A and B, respectively, showing that low back pain was significantly l ighter in group B than in group A (Z= —2.574, P=0.010). At last follow-up, the atrophy ratio of multifidus muscle was 37% ± 13% in group A and was 15% ± 7% in group B, showing significant difference (t=12.674, P=0.000). The multifidus muscle atrophy was rated as grade I in 18 and 44 sides, as grade II in 42 and 32 sides, and as grade III in 30 and 8 sides in groups A and B, respectively, showing significant difference (Z= — 4.947, P=0.000). Conclusion Both traditional open TLIF and minimally invasive TLIF are the effective treatments for single-level DLI. Minimally invasive TLIF has less surgical trauma, sl ighter postoperative systemic inflammatory response, less paravertebral muscle injury, and lower incidence of postoperative back pain, but it has longer operation time.
Objective To evaluate the cl inical outcomes and values of anterior segmental decompression and double-plate fixation (ASDDF) for treatment of ski p cervical spondylotic myelopathy (SCSM). Methods Between June 2005 and June 2008, 17 patients with SCSM were treated with ASDDF. There were 10 males and 7 females with an average age of 58.8 years (range, 41-74 years) and an average disease duration of 9.7 months (range, 6-39 months). According to JapaneseOrthopaedic Association (JOA) score system, 2 patients were rated as extreme severe condition, 7 as severe, 7 as moderate, and 1 as mild. MRI images showed 42 affected cervical disc levels, including 26 disc levels with high-intensity intramedullary lesions on T2, 4 with low-intensity intramedullary lesions on T1, and 12 with significant cord compression but no signal change; according to Nagata classification scale, there were 5 abnormal segments at class I, 21 at class II, and 16 at class III. The rate of fusion, the Cobb angle, and the range of motion (ROM) of the cervical spine were measured preoperatively and postoperatively by the X-ray examinations. The improvement of the neurological function was evaluated by the JOA score. Results The average time of follow-up was 28.6 months (range, 24-58 months). After operation, dysphagia occurred in 2 cases (symptom rel ief after 1 month), hoarseness in 1 case (symptom rel ief after 3 months of methylcobalamin treatment), and degeneration of adjacent segments without symptom in 3 cases. The X-ray films showed the fusion rate of 100% at 12 months after operation without displacement, resorption or collapse of bone graft, and without breakage or loosening of plate and screw. The Cobb angles were (13.3 ± 10.4)° preoperatively, (15.8 ± 10.8)° immediately postoperatively, and (15.4 ± 11.4)° at last follow-up; the ROM of the cervical spine were (41.3 ± 17.4)° preoperatively and (23.8 ± 18.8)° at last follow-up; and the JOA scores were 8.2 ± 2.9 preoperatively, 13.7 ± 3.0 at 12 months postoperatively, and 13.9 ± 2.8 at last follow-up. All indexes showed significant differences between before operation and after operation (P lt; 0.05). The results of JOA scores were excellent in 8 cases, good in 6, fair in 2, and poor in 1 with an average improvement rate of 66.8% (range, 14%-88%) for the neurological function. Conclusion Adequate decompression, high rate of fusion, sol id mechanical stabil ity, improvement of total cervical lordosis,and the neurological function can be achieved through ASDDF for treatment of SCSM.
ObjectiveTo investigate the prevention and control measures and procedures for surgical operation safety during the outbreak of new coronavirus pneumonia.MethodsAfter interpreting the diagnosis and treatment plan of new coronavirus pneumonia, the prevention and control plan of new coronavirus pneumonia, and the technical guidelines for prevention and control of new coronavirus pneumonia infection in medical institutions, we formulated and improved the prevention and control measures and procedures for surgical safety in our hospital.ResultsA total of 567 patients were operated in our hospital from January 22, 2020 to February 10, 2020, including 501 were operated in the surgical center and 66 were operated in the interventional center. Among all the cases, there were 303 emergency operation and 264 scheduled or limited operation. In the emergency operation, the top three were 130 cases of caesarean section (42.9%), 63 cases of abdominal digestive system operation (20.8%) and 31 cases of skull operation (10.2%). In the scheduled or limited operation, the top four were 65 cases of benign diseases of the eye (24.6%), 57 cases of tumor (21.6%), 53 cases of orthopedic surgery (20.1%), and 25 cases of coronary angiography (9.4%). All the patients were successfully completed the operation and recovered well after the operation. No serious surgical complications or infection-related complications occurred.ConclusionDuring the outbreak of new coronavirus pneumonia, surgery and epidemic prevention and control can be carried out by adjusting and optimizing measures and procedures.
Objective To compare the therapeutic effect of conventional discectomy, posterior lumbar interbody fusion (PLIF), and transforaminal lumbar interbody fusion (TLIF) on the recurrent lumbar disc protrusion (RLDP). Methods From January 2000 to January 2008, 65 patients with RLDP underwent different surgical procedures, namely conventional discectomy (group A, 25 cases), PLIF (group B, 22 cases), and TLIF (group C, 18 cases). There were 44 males and 21 females aged 26-65 years old (average 41 years old). All the patients were single-level protrusion, including 33 cases at the L4, 5 level and 32 cases at the L5, S1 level. The primary procedure included laminectomy discectomy in 39 patients, unilateral hemilaminectomy discectomy in 15 patients, and bilateral laminectomy and total laminectomy discectomy in 11patients. The recurrent time to the primary operation was 13-110 months (average 64 months). The location of recurrent disc protrusion was at the ipsilateral side in 47 cases and the contralateral side in 18 cases. No significant differences among three groups were evident in terms of basel ine data (P gt; 0.05). Results The incision all healed by first intention. The incidence of perioperative compl ication in group A (24.0%) and group B (22.3%) was significantly higher than that of group C (5.6%) (P lt; 0.05), and there was no significant difference between group A and group B (P gt; 0.05). The operation time and bleed loss during operation of group B were obviously higher than that of group A and group C (P lt; 0.05), and there was no significant difference between group A and group C (P gt; 0.05). There were no significant differences among three groups in terms of the length of hospital ization (P gt; 0.05). Six-one patients were followed up for 12-36 months (average 20 months). At 1 week after operation, the satisfied rate of patients was 84.0% in group A, 81.8% in group B, and 88.9% in group C (P gt; 0.05). All the patients in group B and group C achieved fusion uneventfully. There were no significant differences among three groups in terms of visual analogue scale (VAS) and Oswestry disabil ity index (ODI) when compared the preoperative value with the final follow-up value (P gt; 0.05). There was significant difference within group A, B, and C in terms of VAS and ODI when compared the preoperative value with the final follow-up value (P lt; 0.05), but there were no significant differences among three groups in the improvement rate (P gt; 0.05). The intervertebral space grading method proposed by Roberts et al. was adopted to evaluate the intervertebral space height (ISH), the preoperative value was 2.04 ± 0.93 in group A, 2.18 ± 0.91 in group B, and 2.11 ± 0.90 in group C, andat the final follow-up, the value was 2.64 ± 0.58 in group A, 1.05 ± 0.59 in group B, and 1.06 ± 0.42 in group C. There were significant differences among three groups in the ISH when compared the properative value with the final follow-up value (P lt; 0.05). Conclusion All of the three surgical procedures are effective for RLDP, but conventional discectomy and PLIF have more compl ications than TLIF. Conventional discectomy may result in the further narrow of the intervertebral space and the occurrence of segment instabil ity, whereas TLIF is safer, more effective, and one of the ideal methods to treat RLDP.
