        • Efficacy analysis of primary closure with two or three endoscopes through cystic duct for treatment of gallbladder stone with secondary common bile duct stones

          ObjectiveTo investigate clinical efficacy and advantages and disadvantages of primary closure with two endoscopes (1aparoscope+choledochoscope) or three endoscopes (laparoscope+choledochoscope+duodenoscope) through the cystic duct for treatment of gallbladder stone with secondary common bile duct (CBD) stones.MethodsThe clinical data of 83 patients with gallbladder stones with secondary CBD stones treated by two or three endoscopes combined with CBD exploration and lithotomy and primary closure through cystic duct from January 2017 to December 2018 in the Chengdu Second People’s Hospital were collected retrospectively. Among them, 41 patients were treated by two endoscopes mode (two endoscopes group), 42 cases were treated by three endoscopes mode (three endoscopes group).ResultsThere were no significant differences in the general conditions such as the gender, age, preoperative diameter of CBD, chronic diseases, etc. between the two and three endoscopes group (P>0.05). All 83 cases underwent the operations successfully and recovered well. The success rate of operation, stone clearance rate, drainage volume of abdominal drainage tube on day 1 after the operation, time of abdominal drainage tube removal after the operation, and hospitalization time had no significant differences between these two groups (P>0.05). The time of operation, intraoperative bleeding volume, and the postoperative pancreatitis rate in the three endoscopes group were significantly more (or higher) than those in the two endoscopes group (P<0.05), but the condition of liver function recovered after the operation was better than that in the two endoscopes group (P<0.05).ConclusionsWith the strict control of the operation indications, it is safe and feasible to use two or three endoscopes through the cystic duct pathway and primary closure of CBD for treatment of gallbladder stone with secondary CBD stones. However, the choice of operative methods of two or three endoscopes should be based on the general situation of the patients before and during the operation.

          ObjectiveTo investigate the effectiveness of percutaneous endoscopic posterior cervical Key-Hole fenestration decompression and nucleus pulposus extirpation in the treatment of paracentral cervical disc herniation.MethodsBetween December 2015 and October 2018, 29 cases of paracentral cervical disc herniation were treated with percutaneous endoscopic posterior cervical Key-Hole fenestration decompression and nucleus pulposus extirpation. There were 16 males and 13 females, with an average age of 49.7 years (range, 39-78 years). The disease duration was 3.5-15.0 months (mean, 6.2 months). The herniated disc located at C3, 4 in 2 cases, C4, 5 in 5 cases, C5, 6 in 9 cases, C6, 7 in 12 cases, and C7, T1 in 1 case. The main symptoms were radiculopathy symptom. The operation time, intraoperative blood loss, hospital stay, and complications were observed and recorded. Visual analogue scale (VAS) score, Japanese Orthopaedic Association (JOA) score, cervical range of motion (ROM), Macnab standard, and cervical segment stability were used to evaluate the efficacy and safety of the operation.ResultsAll patients were followed up 11-43 months, with an average of 19.4 months. The operation time was 67-89 minutes (mean, 73.3 minutes); the intraoperative blood loss was 18-30 mL (mean, 22.9 mL); the hospital stay was 5-10 days (mean, 7.3 days). All the incisions healed by first intention. There was 1 case of hypodynia and hyperalgesia in the affected limb after operation,1 case of decreased limb muscle strength. The VAS scores and JOA scores at each time point after operation were superior to those before operation (P<0.05). There was no significant difference between the time points after operation (P>0.05). At last follow-up, the effectiveness was rated according to the Macnab standard as excellent in 11 cases, good in 15 cases, fair in 2 cases, and bad in 1 case, with an excellent and good rate of 89.7%. The CT and MRI showed the decompression of spinal canal and nerve canal. There was no significant difference in cervical ROM between pre- and post-operation (t=1.427, P=0.165), and no surgical segment instability occurred by X-ray films of flexion and extension of cervical vertebrae.ConclusionFor the paracentral cervical disc herniation with simultaneous compression of nerve roots and spinal cord, percutaneous endoscopic posterior cervical Key-Hole fenestration decompression and nucleus pulposus extirpation has the advantages of small trauma, quick recovery, and satisfactory effectiveness, and can be used as a safe and effective minimally invasive procedure.

        • Effect and effectiveness analysis of different approaches of transforaminal endoscope on extirpation amount of nuclues pulposus

          ObjectiveTo investigate the effect and effectiveness analysis of different approaches of transforaminal endoscope on extirpation amount of nuclues pulposus.MethodsBetween August 2011 and December 2014, a total of 165 patients with lumbar disc herniation were retrospectively enrolled and were treated with nucleus pulposus discectomy through transforaminal endoscope. The patients were randomly divided into 4 groups according to different approach of transforaminal endoscope. The posterolateral approach (Yeung’s technology) was used in group A (42 cases), transforaminal endoscopic spine system (TESSYS) technology was used in group B (40 cases), improved transforaminal endoscopic access (ITEA) technology was used in group C (43 cases), and interlaminar approach (40 cases) was used in group D (40 cases). There was no significant difference in gender, age, disease duration, symptomatic side, and segments among 4 groups (P>0.05). The extirpation amount of nuclues pulposus was calculated and compared among 4 groups; the effectiveness was evaluated by pre- and post-operative visual analogue scale (VAS) score, Oswestry disability index (ODI), lumbar curvature index (LCI), and intervertebral height.ResultsThe discectomy amount of nucleus pulposus was (3.7±0.8), (3.6±0.7), (4.5±1.1), and (3.0±0.8) cm3 in groups A, B, C, and D, respectively. The amount of group C was significantly larger than that of the other 3 groups (P<0.05), and the amount of group D was significantly smaller than that of the other 3 groups (P<0.05); no significant difference was found between groups A and B (P>0.05). Cerebrospinal fluid leakage was found in 1 case; no other postoperative complications including intervertebral space infection and epidural hematoma was found. All the incisions healed by first intension. All the patients were followed up 12-24 months (mean, 18 months), and no typical symptoms of recurrence was found during the follow-up period. There was no significant difference in preoperative lower back pain VAS score, lower extremities VAS score, and ODI scores among 4 groups (P>0.05). The above scores at last follow-up were significantly improved when compared with preoperative ones in each group (P<0.05), but no significant difference of above scores and recovery values was found among 4 groups (P>0.05). The difference in LCI and intervertebral height at preoperation and at last follow-up were not significant between 4 groups (P>0.05). The difference in LCI and intervertebral height of each group between at preoperation and last follow-up were not significant (P>0.05). And the recovery value of LCI and the lost of height at last follow-up also showed no significant differences between 4 groups (P>0.05).ConclusionThe ITEA technology can give a wider field of view than other technologies. It is more convenient to find and remove the nucleus pulposus. However, the appropriate operative approaches should be chosen according to the symptoms and characteristics of lumbar disc herniation.

        • Diagnosis and treatment of esophageal foreign body: Operation or endoscopy?

          ObjectiveTo summarize our experience in the treatment of esophageal foreign bodies.MethodsA retrospective analysis of 149 patients of esophageal foreign bodies in the Second Affiliated Hospital of Air Force Military Medical University from December 2011 to May 2019 was carried out, including 75 (50.3%) females and 74 (49.7%) males with an average age of 57 (2-85) years.ResultsThere were 146 patients confirmed by endoscopy, and 3 patients were not found foreign body. Among the confirmed patients, 127 patients were removed by gastroscope and 19 patients were treated by operation. Esophageal foreign bodies are mainly related to the types of food. Jujube seed is the most common food foreign body in the northwest China. The injury rate of mucosal was 47.54% within 48 hours. The complication rate of taking out the foreign body after 48 hours was 100.0%. The success rate by endoscopy decreased (P=0.005), if the foreign body combined perforation. There was no statistical difference between the neck and other parts when using ultra-fine gastroscope (P=0.157).ConclusionThe sharper the foreign body is, the easier the perforation is. The earlier the foreign body is removed, the less complications are. The size of the foreign body determines the difficulty of endoscopic removal. Gastroscopy is the first choice for diagnosis and treatment, especially ultra-fine gastroscopy, and the foreign bodies that cannot be removed by endoscopy need surgical treatment.

        • Effectiveness analysis of posterolateral approach lumbar interbody fusion assisted by one-hole split endoscope for L4, 5 degenerative lumbar spondylolisthesis

          Objective To compare the effectiveness of posterolateral approach lumbar interbody fusion assisted by one-hole split endoscope (OSE) and traditional posterior lumbar interbody fusion (PLIF) in the treatment of L4, 5 degenerative lumbar spondylolisthesis (DLS). Methods The clinical data of 58 patients with DLS who met the selection criteria admitted between February 2020 and March 2022 were retrospectively analyzed, of which 26 were treated with OSE-assisted posterolateral approach lumbar interbody fusion (OSE group) and 32 were treated with PLIF (PLIF group). There was no significant difference between the two groups in terms of gender, age, body mass index, Meyerding grade, lower limb symptom side, decompression side, stenosis type, and preoperative low back pain visual analogue scale (VAS) score, leg pain VAS score, Oswestry disability index (ODI), and the height of the anterior and posterior margins of the intervertebral space (P>0.05). The operation time, intraoperative blood loss, postoperative hospital stay, and complications were compared between the two groups. The low back pain and leg pain VAS scores and ODI before operation, at 1 month, 6 months after operation, and last follow-up, the height of anterior and posterior margins of the intervertebral space before operation, at 6 months after operation, and last follow-up, the modified MacNab criteria at last follow-up after operation were used to evaluate the effectiveness; and the Bridwell method at last follow-up was used to evaluate the interbody fusion. Results Both groups successfully completed the operation. Compared with the PLIF group, the OSE group showed a decrease in intraoperative blood loss and postoperative hospital stay, but an increase in operation time, with significant differences (P<0.05). In the OSE group, no complication such as nerve root injury and thecal sac tear occurred; in the PLIF group, there were 1 case of thecal sac tear and 1 case of epidural hematoma, which were cured after conservative management. Both groups of patients were followed up 13-20 months with an average of 15.5 months. There was no complication such as loosening, sinking, or displacement of the fusion cage. The low back pain and leg pain VAS scores, ODI, and the height of anterior and posterior margins of the intervertebral space at each time point after operation in both groups were significantly improved when compared with those before operation (P<0.05). Except for the VAS score of lower back pain in the OSE group being significantly better than that in the PLIF group at 1 month after operation (P<0.05), there was no significant difference in all indicators between the two groups at all other time points (P>0.05). At last follow-up, both groups achieved bone fusion, and there was no significant difference in Bridwell interbody fusion and modified MacNab standard evaluation between the two groups (P>0.05). Conclusion OSE-assisted posterolateral approach lumbar interbody fusion for L4, 5 DLS, although the operation time is relatively long, but the postoperative hospitalization stay is short, the complications are few, the operation is safe and effective, and the early effectiveness is satisfactory.

        • Efficacy and prognostic factors of neuroendoscopic intracerebral hematoma evacuation in the treatment of hypertension-related intracerebral hemorrhage

          ObjectivesTo explore the efficacy and prognostic factors of neuroendoscopic intracerebral hematoma evacuation in the treatment of hypertension-related intracerebral hemorrhage.MethodsA total of 122 patients with hypertension-related intracerebral hemorrhage treated in our hospital from October 2015 to May 2019 were categorized into experimental group (n=62) and control group (n=60). The experimental group was treated with endoscopic intracerebral hematoma removal, while the control group was treated with traditional craniotomy. The operative indexes, postoperative recovery, serum endothelin, IL-6, CRP levels and the incidence of postoperative complications were observed and compared between the two groups, and the relevant factors affecting the prognosis of patients undergoing neuroendoscopic intracerebral hematoma evacuation were analyzed.ResultsThe operation time, intraoperative blood loss, hematoma clearance rate, ICU treatment time, the volume of brain edema 7 days after operation, the postoperative intracranial pressure, NIHSS score and ADL score in experimental group were significantly superior to those in control group. The levels of serum endothelin, IL-6 and CRP in the experimental group were significantly lower than those in the control group after operation. The incidence of complications in the experimental group was lower than that in control group. Univariate analysis showed that the prognosis of patients undergoing neuroendoscopic evacuation of intracerebral hematoma was significantly correlated with the history of hypertension, preoperative GCS score, the amount of bleeding and whether been broken into the ventricle (P<0.05), but not with age, sex and location of hemorrhage (P>0.05). Multivariate logistic regression analysis showed that the history of hypertension above 10 years, blood loss above 50 mL, intraventricular rupture and preoperative GCS score were the risk factors affecting the prognosis of patients undergoing neuroendoscopic intracerebral hematoma evacuation.ConclusionsCompared with traditional craniotomy, neuroendoscopic evacuation of intracerebral hematoma has the advantages of better curative effect and lower incidence of postoperative complications in the treatment of hypertension-related intracerebral hemorrhage. The history of hypertension above 10 years, bleeding volume above 50 mL, breaking into the ventricle and preoperative GCS score are the risk factors affecting the prognosis of patients undergoing neuroendoscopic intracerebral hematoma evacuation.

        • SPINAL CANAL DECOMPRESSION WITH MICROENDOSCOPIC DISECTOMY AND PILLAR VERTEBRAL SPACE INSERTION FOR THORACOLUMBAR NEGLECTED FRACTURE

          Objective To investigate the effectiveness of spinal canal decompression with microendoscopic disectomy (MED) and pillar vertebral space insertion through pedicle of vertebral arch for thoracolumbar neglected fracture. Methods Between February 2006 and November 2009, 30 patients with thoracolumbar neglected fracture were treated by spinal canal decompression with MED and pillar vertebral space insertion through pedicle of vertebral arch. There were 22 males and 8 females with an average age of 36.2 years (range, 17-58 years). The disease duration was 6 weeks to 14 months with an average of 5.3 months. All patients had single vertebral compression fracture, including T9 in 1 case, T11 in 2 cases, T12 in 5 cases, L1 in 11 cases, L2 in 5 cases, L3 in 5 cases, and L4 in 1 case. The preoperative Cobb angle was (27.5 ± 7.5) ° . The preoperative height of vertebrae was (26.67 ± 5.34) mm. The visual analogue score (VAS) was 5.8 ± 1.4. According to Wolter classification for spinal canal stenosis, there were 17 cases of grade 1, 10 cases of grade 2, and 3 cases of grade 3. According to Frankel grade, 3 cases were in grade A, 8 cases in grade B, 13 cases in grade C, and 6 cases in grade D. Results The average operation time was 70 minutes (range, 40-120 minutes) and the average blood loss was 180 mL (range, 100-400 mL). The hematoma occurred in 1 case, and other incisions healed by first intension. No deep vein thrombosis of the lower extremity occurred. All patients were followed up 26 months on average (range, 24-46 months). The Cobb angle and vertebral height at 3 days and last follow-up were significantly improved when compared with ones before operation (P lt; 0.01). At last follow-up, the spinal canal stenosis was grade 0 in 27 cases and grade 1 in 3 cases according to Wolter classification. At 24 months after operation, the spinal function was obviously improved; 1 case was in grade A, 1 case in grade B, 3 cases in grade C, 9 cases in grade D, and 16 cases in grade E according to Frankle grade, showing significant differences when compared with preoperative ones (P lt; 0.05). The VAS score at 1 month after operation was significantly higher than that before operation (P lt; 0.01), then the score showed downtrend along with time, and it was significantly lower at 24 months after operation than before operation (P lt; 0.01). Conclusion Spinal canal decompression with MED and pillar vertebral space insertion for thoracolumbar neglected fracture has short surgical time, less blood loss, and satisfactory reduction, but higher technical requirement is necessary for MED.
