Objective
To explore the feasibility and safety of non-gastrointestinal decompression after esophagectomy and the necessity of gastric tube or the time to remove gastric tube.
Methods
Thirty patients with esophageal cancer who underwent surgical treatment in the Department of Thoracic and Cardiovascular Surgery, Nanjing Drum Tower Hospital, were included in the trial from June to October 2017. The patients were randomly and equally assigned to a trial group (non-gastrointestinal decompression) or a control group (gastrointestinal decompression). There was no significant difference in age (P=1.000), sex (P=1.000), tumor location (P=0.732), pathological type (P=1.000), pathological stage (P=0.507), and operation time (P=0.674) between the two groups. The clinical effect between the two groups were compared.
Results
There was no statistical difference in incidences of anastomotic leakage (P=1.000), anastomotic bleeding (P=1.000), gastroesophageal reflux (P=1.000) between the two groups. And there was no statistical difference in time of the first flatus (P=0.629) and the first bowel movement (P=0.599) after operation between the two groups.
Conclusion
Without gastrointestinal decompression after Ivor Lewis esophagectomy does not increase the incidences of anastomotic leakage, anastomotic bleeding and gastroesophageal reflux, and has no significant effect on the recovery of gastrointestinal function. Without gastrointestinal decompression after Ivor Lewis esophagectomy is safe and feasible. Removing gastric tube on the second day after operation is reasonable and feasible.
Objective
To observe and measure the approach next to the erector spinae in the thoracic and lumbar segments of the spine and adjacent anatomical structures by the topographic method, to clarify the positioning method and safe range so as to provide the anatomical basis of the approach for spinal canal decompression.
Methods
Twelve formaldehyde-treated adult cadaver specimens were selected, including 6 males and 6 females with an average age of 43 years (range, 27-52 years) and with an average height of 166 cm (range, 154-177 cm). The related data of the approach at T1-S1 levels were respectively measured: the distance between the lateral edge of the erector spinae and the spinous process, the length of the approach, the angle between the approach and the horizontal plane, the size of intervertebral foramen, and the vertical distance between the segmental artery and the upper edge of the vertebrae.
Results
The distance between the lateral edge of the erector spinae and the spinous process ranged from (41.75 ± 3.29) mm to (74.54 ± 7.08) mm. The length of the approach ranged from (66.75 ± 10.81) mm to (97.13 ± 13.35) mm. The angle between the approach and the horizontal plane ranged from (38.38 ± 6.16)° to (53.67 ± 4.40)°. The vertical distance between the segmental artery and the upper edge of the vertebrae ranged from (9.50 ± 0.60) mm to (18.30 ± 1.56) mm. The size of foraminal was also measured. The spinal canal could reach when iliocostalis lateral edge was used as the starting point in the lumbar segments, and longissimus lateral edge as the starting point in the thoracic segments. It was confirmed that there was enough safe space for the spinal decompression without the resection of the articular process.
Conclusion
The approach next to the erector spinae can reach spinal canal to achieve the purpose of decompression through the intervertebral foramen. The minimally invasive approach is feasible and safe. It has the value of the operative application.
ObjectiveTo evaluate the effectiveness of comprehensive management for early stage avascular necrosis of the femoral head (ANFH) by arthroscopic minimally invasive surgery by comparing with closed core decompression. MethodsBetween January 2007 and March 2010, 28 patients (33 hips) with early stage ANFH were treated with the procedure of arthroscopic core decompression combined with autogenous cancellous bone graft and bone morphogenetic protein (BMP) in 18 cases (21 hips, trial group) or with simple closed core decompression in 10 cases (12 hips, control group). No significant difference was found in gender, age, disease duration, etiology, and staging between 2 groups (P gt; 0.05). ResultsIncision healed primarily in all patients, and no infection occurred. All patients were followed up 2.5 years on average (range, 1-3 years). Pain relief and improvement of hip function were obtained in all patients at 6 months after operation. At last follow-up, the Harris scores were 85.67 ± 4.78 in trial group and 81.33 ± 7.03 in control group, showing significant difference between 2 groups (t= —2.10, P=0.04). Collapse of the femoral head was observed in 1 hip (Ficat stage II) of trial group, and in 2 hips (Ficat stage I ) and 2 hips (Ficat stage II) of control group; hip arthroplasty was performed. Significant difference in total effective rate was found between trial group and control group (95.24% vs. 66.67%; χ2=4.85, P=0.03). ConclusionArthroscopic core decompression combined with autogenous cancellous bone graft and BMP is more effective than traditional closed core decompression for treatment of early stage ANFH in pain relief, improvement of hip function, slowing-down the process of femoral head necrosis, reduction of hip joint replacement by accurate location of the lesions, and thoroughly debridement of necrotic bone.
【Abstract】Objective To discuss the clinical significance of postoperative application of gastrointestinal decompression after anastomosis of lower digestive tract. Methods Three hundred and sixty-eight patients undergoing excision and anastomosis of lower digestive tract were divided into two groups: the group with postoperative gastrointestinal decompression and the group without it. The clinical therapeutic outcomes and incidences of complications were compared between the two groups. Results The volume of gastric juice in the decompression group was about 200 ml every day after operation. Both groups had a smaller abdomenal circumference before operation than after operation （P＜0.001）. No difference in the time of first passage of gas from anus and defecation after operation was found between the two groups. The incidence of complications in the decompression group was obviously higher than that of non-decompression group (28.0% vs. 8.2%, P＜0.001); the incidence of pharyngolaryngitis of the former was up to 23.1%. There was also no difference found between these two groups regarding the hospital stay after operation.Conclusion The present study shows that application of gastrointestinal decompression after excision and anastomosis of lower digestive tract cannot effectively reduce the gastrointestinal tract pressure and has no obvious effect on prevention from postoperative complications. On the contrary, it may increase the incidence of pharyngolaryngitis and other complications. Therefore, it is more beneficial for the recovery of patients without gastrointestinal decompression.
Objective To compare the effectiveness of percutaneous endoscopic transforaminal lumbar interbody fusion (PE-TLIF) and Wiltse-approach TLIF (W-TLIF) in the treatment of lumbar spondylolisthesis. MethodsThe clinical data of 47 patients with lumbar spondylolisthesis who met the selection criteria between July 2018 and June 2019 were retrospectively analyzed, in which 21 patients were treated with PE-TLIF (PE-TLIF group) and 26 patients were treated with W-TLIF (W-TLIF group). There was no significant difference between the two groups in age, gender, disease duration, level of spondylolisthesis vertebrae, spondylolisthesis degree, spondylolisthesis type, and preoperative visual analogue scale (VAS) score of low back pain and leg pain, lumbar Japanese Orthopaedic Association (JOA) score, and the disc height (DH), segmental lordosis (SL), and Taillard index (TI) of the operated vertebrae (P>0.05). The operation time, intraoperative blood loss, postoperative drainage, postoperative bedridden time, and complications were compared between the two groups. The VAS score and JOA score were used to evaluate the improvement of pain and function. At last follow-up, DH, SL, and TI of operated vertebrae were measured by X-ray films, and lumbar CT was performed to evaluate the interbody fusion. Results Compared with W-TLIF group, the operation time in PE-TLIF group was significantly longer, but the intraoperative blood loss and postoperative drainage were significantly less, and the postoperative bedridden time was significantly shorter (P<0.05). There were 2 cases of transient lower limb radiating pain in PE-TLIF group and 1 case of superficial incision infection in W-TLIF group. There was no significant difference in the incidence of complications (9.5% vs. 3.8%) between the two groups (χ2=0.037, P=0.848). The patients in both groups were followed up 12-24 months, with an average of 17.3 months in PE-TLIF group and 17.7 months in W-TLIF group. The VAS scores of low back pain and leg pain, and the JOA scores of the two groups significantly improved at each time point after operation when compared with those before operation (P<0.05). Compared with W-TLIF group, the VAS scores of low back pain in PE-TLIF group significantly lower at 3 days and 3 months after operation (P<0.05), and the JOA score of PE-TLIF group was significantly higher at 3 months after operation (P<0.05), and there was no significant difference in each score at any other time point between the two groups (P>0.05). At last follow-up, the DH, SL, and TI of operated vertebrae of the two groups significantly improved when compared with those before operation (P<0.05), and there was no significant difference in the differences of each parameter between the two groups (P>0.05). According to Suk’s standard, the fusion rates of PE-TLIF group and W-TLIF group were 90.5% (19/21) and 92.3% (24/26), respectively, with no significant difference (χ2=0.000, P=1.000). At last follow-up, there was no case of Cage sunk into the adjacent vertebral body, or dislodgement of Cage anteriorly or posteriorly in both groups. Conclusion PE-TLIF and W-TLIF are both effective in the treatment of grade Ⅰ and Ⅱ lumbar spondylolisthesis. Although the operation time is prolonged, PE-TLIF has less intraoperative blood loss and postoperative drainage, shorter postoperative bedridden time, and can get more obvious short-term improvement of low back pain and function.
ObjectiveTo investigate the early effctiveness of oblique lateral interbody fusion (OLIF) combined with pedicle screw fixation via small incision Wiltse approach for the treatment of lumbar spondylolisthesis.MethodsBetween January 2016 and December 2016, 21 patients with lumbar spondylolisthesis were treated with OLIF and pedicle screw fixation via small incision Wiltse approach. There were 9 males and 12 females, aged 57-73 years, with an average age of 64.5 years. The disease duration was 24-60 months, with an average of 34.6 months. All cases were spondylolisthesis at L4 (15 cases of degreeⅠ, 6 cases of degreeⅡ); 1 case had vertebral arch isthmus, and 20 cases had spinal stenosis. Japanese Orthopaedic Association (JOA) scoring system was used to evaluate the effectiveness before operation and at last follow-up. Before operation and at 2 days after operation, anteroposterior and lateral X-ray films and CT were taken to measure the sagittal diameter and cross-sectional area of the spinal canal, and calculate the intervertebral height and degree of spondylolisthesis. At 6 months after operation, the intervertebral fusion was evaluated by CT.ResultsThe operation time was 120-180 minutes, with an average of 155 minutes; the intraoperative blood loss was 100-340 mL, with an average of 225.5 mL. One patient had slight injury of lower endplate, 1 patient had numbness of thigh and weakness of hip flexion after operation, 1 patient had sympathetic nerve trunk injury. All the cases were followed up 12-18 months, with an average of 14.3 months. The symptoms of low back pain, leg pain, and numbness of lower limbs significantly relieved after operation, and there was no complication such as protrusion of fusion cage, screw breakage, and endplate collapse. At 2 days after operation, the intervertebral height, degree of spondylolisthesis, sagittal diameter of spinal canal, and cross-sectional area of spinal canal significantly improved compared with preoperative ones (P<0.05). At 6 months after operation, CT showed that 1 patient had poor interbody fusion (grade Ⅲ), the other 20 patients had good interbody fusion (grade Ⅰ and Ⅱ), and the interbody fusion rate was 95.2%. At last follow-up, JOA score of lumbar spine significantly increased compared with that before operation (t=24.980, P=0.000).ConclusionOLIF combined with pedicle screw fixation via small incision Wiltse approach for the lumbar spondylolisthesis has minimally invasive features, such as less trauma, fewer complications, and higher intervertebral fusion rate. It is a safe and effective method.
Objective To review the application and progress of different minimally invasive spinal decompression in the treatment of lumbar spinal stenosis (LSS). Methods The domestic and foreign literature on the application of different minimally invasive spinal decompression in the treatment of LSS was extensively reviewed, and the advantages, disadvantages, and complications of different surgical methods were summarized. ResultsAt present, minimally invasive spinal decompression mainly includes microscopic bilateral decompression, microendoscopic decompression, percutaneous endoscopic lumbar decompression, unilateral biportal endoscopy, and so on. Compared with traditional open surgery, different minimally invasive spinal decompression techniques can reduce the operation time, intraoperative blood loss, and postoperative pain of patients, thereby reducing hospital stay and saving treatment costs. Conclusion The indications of different minimally invasive spinal decompression are different, but there are certain advantages and disadvantages. When patients have clear surgical indications, individualized treatment plans should be formulated according to the symptoms and signs of patients, combined with imaging manifestations.
In recent years, enhanced recovery after surgery (ERAS) has been widely used in spine surgery and achieved satisfactory results. In order to standardize the ERAS implementation process and application in percutaneous endoscopic interlaminar lumbar decompression/discectomy (PEID), we reviewed the literatures and cited evidence-based medicine data, and had a national comprehensive discussion among experts of the Group of Minimally Invasive Spinal Surgery and Enhanced Recovery, Professional Committee of Orthopedic Surgery and Enhanced Recovery, Association of China Rehabilitation Technology Transformation and Promotion. Altogether, the up-to-date expert consensus have been achieved. The consensus may provide the reference for clinical treatment in aspect of the standardization of surgical operations, the reduction of surgical trauma and complications, the optimization of perioperative pain and sleep management, the prevention of venous thrombosis, and the guidance of patients’ functional training and perioperative education.
Anterior cervical decompression and fusion (ACDF) treatment for cervical spondylosis has been more than half a century, and achieved good clinical results. However, with the continuous extension of follow-up time, the fusion segment-associated postoperative complications emerged gradually. Reserved cervical stability and activity, the concept of non-fusion was born. As a non-fusion technique, cervical artificial disc replacement (CADR) developed rapidly. With the continuous development of artificial prosthesis materials and design concepts, and specification and proficiency of surgical procedures, CADR has achieved better short- and mid-term clinical efficacy than ACDF. Compared with ACDF, the main advantages of CADR are that the postoperative recovery is quick, the activity and stability of cervical vertebra are maintained, the height of cervical intervertebral space is restored, and the stress of adjacent segments and the rate of surgical renovation are reduced. In clinical work, as an emerging technology, CADR requires spine surgeons to control the surgical indications, contraindications, and patients’ conditions strictly. This article reviews the research progress of CADR in order to provide new ideas for clinical treatment of cervical spondylosis.
Objective
To evaluate the long-term effectiveness of treating early-middle stage avascular necrosis of the femoral head (ANFH) with core decompression and bone grafting.
Methods
Between January 2000 and December 2006, 87 ANFH patients (114 hips) were treated with core decompression and bone grafting, including 54 cases (62.1%) of alcohol-induced ANFH, 26 cases (29.9%) of steroid-induced ANFH, and 7 cases (8.0%) of idiopathic ANFH. There were 74 males (97 hips) and 13 females (17 hips), aged 20-56 years (mean, 38 years). The disease duration was 3-46 months (mean, 18 months). According to Ficat staging, 16 hips were at stage I, 68 hips at stage II, and 30 hips at stage III. The Harris score and Ficat stage were compared between pre- and post-operation to assess the outcomes clinically and radiologically. The hip survival was analyzed by the Kaplan-Meier method.
Results
Eighty-seven patients were followed up 5 years to 11 years and 10 months (mean, 8 years and 9 months). The Harris hip score was significantly increased from 73.13 ± 7.17 at preoperation to 81.59 ± 13.23 at postoperation (t=
—
9.318, P=0.000). The clinical success rate was 69.3% (79/114) and the radiological success rate was 54.4% (62/114). Kaplan-Meier survival analysis showed that the overall survival rate was 84.2% (96/114); the survival rates of Ficat stage I [100% (16/16)] and stage II [91.2% (62/68)] were higher than that of stage III [60.0%(18/30)] (P lt; 0.01); there was no significant difference between Ficat stage I and II (χ2=1.520, P=0.218).
Conclusion
Core decompression with bone grafting is a safe and effective procedure for the treatment of Ficat stages I-II (early stage) ANFH, and the long-term effectiveness is satisfactory. But the long-term effectiveness is unsatisfactory for the patients at the Ficat stage III (middle stage).
