Objective To investigate the etiology, pathogenesis, clinical manifestations, diagnosis and treatment of acute obstructive suppurative pancreatic ductitis (AOSPD). Method The literature reports on AOSPD at home and abroad were reviewed and analyzed comprehensively based on clinical experience. Results AOSPD was a rare clinically infectious disease of purulent pancreatic duct. Chronic pancreatitis and ampullary operations were the main pathogenesis factors. The clinical symptoms were non-specific, and the imaging manifestations were pancreatic duct dilatation and pancreatic duct calculi. The clinical diagnosis was mainly determined by epigastrium CT or endoscopic retrograde cholangiopancreatography, which was easy to be misdiagnosed and missed. Conclusion The clinical diagnosis of AOSPD is difficult, early pancreatic duct drainage is the key to the treatment, and attention should be paid to its diagnosis and treatment.
OBJECTIVE: To investigate the therapeutic effect of subfascial endoscopic perforator vein surgery (SEPS) in treatment of varicose of the lower limb. METHODS: From 1999. 11 to 2000. 12, 108 patients with varicose of the lower limb underwent venous surgery and 34 of them were treated by SEPS. There were 16 males and 18 females aged 20-79(averaged 51.4 years). Thirty limbs (26 cases) had open ulcers and the diameter of ulcer was 1.5-12.0 cm. Eleven limbs (8 cases) had severe pigmentation and the skin changes had been presented for 1 month to 15 years. According to the severity of illness, flush saphenofemoral ligation, great saphenous vein stripping, percutaneous continuous venous circum suture, external femoral vein valve repair and SEPS were performed separately or simultaneously. RESULTS: Active ulcers healed in 19 limbs after 1 month, in 7 limbs after 3 months, and in the other 4 ulcers after skin transplantation. There was no ulcer recurrence during follow-up (ranged 9-22 months). CONCLUSION: SEPS can accelerate the healing of venous ulcers, and it is one of important methods in the treatment of chronic venous insufficiency.
ObjectiveTo compare the effectiveness and safety of laparoscopic cholecystectomy (LC) plus laparoscopic common bile duct exploration (LCBDE) with LC plus endoscopic retrograde cholangiopancreatography (ERCP) for patients with concomitant cholelithiasis and choledocholithiasis by using meta-analysis.MethodsWe searched PubMed, Cochrane Library、EMBASE, Chinese Biomedical Literature Database, Chinese Science and Technology Academic Journal, Chinese Journal Full-text Database and Wanfang database to identify relevant articles from their inception to 31 October 2018. A meta-analysis was carried out using the RevMan 5.3 software.ResultsA total of 13 RCTs were included in this meta-analysis, 747 cases received LC+LCBDE and 761 cases underwent LC+ERCP. The meta-analysis results showed that no significant difference between the LC+LCBDE group and the LC+ERCP group in terms of common bile duct (CBD) stone clearance rate [RR=0.99, 95%CI (0.95, 1.02), P=0.87] and overall complications [RR=0.94, 95%CI (0.72, 1.22), P=0.64]. The LC+LCBDE group had higher rate of postoperative bile leakage rate [RR=3.87, 95%CI (2.01, 7.42), P<0.000 1] than that LC+ERCP group. However, the LC+LCBDE group had lower rate of postoperative pancreatitis [RR=0.28, 95%CI (0.14, 0.55), P=0.002] than that LC+ERCP group.ConclusionsBoth LC+LCBDE and LC+ERCP are equivalent in CBD stone clearance rate and overall complications, LC+LCBDE is associated with a higher postoperative bile leakage rate and lower rate of postoperative pancreatitis, appropriate treatment should be selected according to the individual patient’s condition.
Objective To investigate the feasibility, effectiveness, and security of percutaneous endoscopic spine surgery for treatment of lumbar spine disorders with intraspinal ossification. Methods Between July 2008 and June 2016, 96 patients with lumbar spine disorders (lumbar disc herniation or lumbar spinal stenosis) with intraspinal ossification were treated with percutaneous endoscopic spine surgery. There were 59 males and 37 females, aged from 13 to 57 years (mean, 29.5 years). The disease duration was 3-51 months (mean, 18.2 months). Fifty-one cases had trauma history. Ninety-two cases were single segmental unilateral symptom, 4 cases were bilateral symptom. The ossification property was posterior ring apophysis separation in 89 cases, and ossification of the fibrous ring or posterior longitudinal ligament in 7 cases. There were 32 cases of lateral type, 13 cases of central type, and 51 cases of mixed type. The pressure factors, such as nucleus pulposus, hyperplasia of the yellow ligament, joint capsule, or articular osteophyma, were removed under the microscope. Local anesthesia or continuous epidural anesthesia was performed in the transforaminal approach with 50 cases, and continuous epidural anesthesia or general anesthesia was performed in the interlaminar approach with 46 cases. The visual analogue scale (VAS) score was used to evaluate the degree of leg pain preoperatively and at last follow-up. The effectiveness was evaluated at last follow-up according to the modified Macnab criteria. Results All patients were successfully operated. Via transforaminal approach, the mean operation time was 53 minutes and the mean intraoperative fluoroscopy times was 8 times; and via interlaminar approach was 58 minutes and 3 times, respectively. The mean bed rest time after operation was 6.5 hours and the mean hospitalization time was 4.7 days. All patients were followed up 6-18 months (median, 11 months). Postoperative lumbar CT scan and three-dimensional reconstruction after 3 days of operation showed that ossification tissues of 26 cases were not resected, 12 cases were resected partly, and 49 cases were resected completely. Postoperative lumbar MRI after 3 months of operation showed that spinal cord and nerve root were not compressed. At last follow-up, VAS score of leg pain was 0.7±1.1, which was significantly lower than preoperative score (5.8±1.1) (t=1.987, P=0.025). At last follow-up, according to modified Macnab criteria, the results were excellent in 87 cases, good in 5 cases, and fair in 4 cases, and the excellent and good rate was 95.8%. Conclusion Percutaneous endoscopic spine surgery for treatment of lumbar spine disorders with intraspinal ossification is an effective, safe, and minimal invasive alternative, and the short-term effectiveness is reliable. Accounting for the treatment of intraspinal ossification, comprehensive analysis should be made by combining clinical symptoms, imaging characteristics, and risk assessment.
ObjectiveTo explore the clinical efficacy of percutaneous endoscopic interlaminar discectomy (PEID) and interlaminar fenestration discectomy in the treatment of lumbar (L) 5-Sacral (S) 1 lumbar disc herniation (LDH).MethodsLDH patients were retrospectively included from January 2016 to Januray 2018. And the patients were divided into the PEID group and the fenestration group according to their choice of different surgical methods. The operation time, intra-operative blood loss, and bed rest time in the two groups were recorded. The preoperative and postoperative [1 week, 1 month, 3 months, and last follow-up (>12 months)] Visual Analogue Score (VAS) of the lumbago and leg pain between the two groups were compared; the preoperative and postoperative [1 week, and last follow-up (>12 months)] Oswestry Disability Index (ODI) and also the postoperative [(>12 months)] therapeutic effect (modified MacNab) between the two groups were compared.ResultsA total of 66 patients were included, with 31 in the PEID group and 35 in the fenestration group. There was no significant difference in age, gender and course of disease between the two groups (P>0.05). There were leakage of cerebrospinal fluid and transient lumbago, leg pain and numbness, which were worse than those before operation in the PEID group (1 and 1 patient, respectively) and the fenestration group (2 and 3 patients, respectively). There were statistically significant differences between the PEID group and the fenestration group, in the operative time [(90.65±9.98) vs. (66.23±16.50) minutes], intra-operative blood loss [(51.77±18.64) vs. (184.29±78.38) mL], and bed time [(2.87±0.92) vs. (7.49±1.20) d] (t=?7.365, t’=?9.697, t=?17.374, P<0.001). There was no significant difference in the preoperative VAS score (lumbar-leg pain) and ODI index, and the ODI index at each postoperative time point, between the two groups (P>0.05). VAS score (lumbago) and VAS score (leg pain) in the PEID group at each postoperative time point were lower than those in the fenestration group (P<0.05); VAS scores (leg pain) at other time points were not statistically significant between the two groups (P > 0.05). VAS (lumbar-leg pain) score and ODI index at each postoperative time point were lower than those before the surgery. The was no statistically significant difference in the PEID group (90.32%) and fenestration group (85.71%) in the excellent rate (χ2=0.328, P=0.713).ConclusionsPEID has less surgical trauma, less bleeding, short bed rest, fast recovery, and better relief of postoperative lumbago symptoms. It is worthy of further promotion in clinical work.
Objective To compare the difference in efficacy of early precut of pancreatic duct sphincter and pancreatic duct stent placement in the prevention of pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP) during high-risk patients. Methods A prospective study was conducted on 61 eligible patients who underwent ERCP treatment in Department of Hepatobiliary Surgery of The First Affiliated Hospital of Xi’an Jiaotong University and Xianyang Hospital of Yan’an University, from November 2016 to November 2017. All cases were randomly divided into early pancreatic sphincterotomy group (n=30) and pancreatic duct stenting group (n=31) . The success rate of intubation, intubation, and incidence of complication were compared. Results There was no significant difference in the success rate of the first intubation between the 2 groups (P=0.580), but the intubation time of the early pancreatic sphincterotomy group was shorter than that of the pancreatic duct stenting group (P=0.007). In the early pancreatic sphincterotomy group, there was 1 case of post-ERCP pancreatitis, 1 case of biliary tract infection, and 1 case of postoperative bleeding. In the pancreatic duct stenting group, there was 1 case of post-ERCP pancreatitis, and 2 cases of biliary tract infection. No severe complications such as perforation or severe acute pancreatitis occurred in both 2 groups. There was no significant difference in the incidence of total complications and specified complication (included post-ERCP pancreatitis, biliary tract infection, and postoperative bleeding) between the 2 groups (P>0.05). Conclusions Thereis no significant difference in the incidence of postoperative pancreatitis after early precut of pancreatic duct sphincter and pancreatic duct stenting placement in patients with high-risk, but intubation time of early precut of pancreatic duct sphincter method is shorter than the pancreatic duct stenting placement method.
Objective To compare microendoscopic discectomy (MED) with open discectomy (OD) for degenerative lumbar spinal stenosis in terms of cl inical outcomes, and provide experience and therapeutic evidence for cl inical appl ication.Methods From May 2002 to October 2007, 215 patients with lumbar spinal stenosis were randomized into two groups, and underwent either MED or OD. In group A, 105 patients underwent MED, including 56 males and 49 females aged 34 to 83 years old (average 45 years old); the duration of the disease ranged from 9 months to 26 years (average 50 months); the spinal stenosis involved one segment in 76 cases, two segments in 27 cases, and three segments in 2 cases. In group B, 110 patients received OD, including 57 males and 53 females aged 35 to 85 years old (average 47 years old); the duration of the disease ranged from 8 months to 25 years (average 48 months); the spinal stenosis involved one segment in 78 cases, two segments in 29 cases, and three segments in 3 cases. No significant difference was evident between two groups in terms of the general information(P gt; 0.05). Results Operation was successfully performed in all cases. Volume of intraoperative blood loss was (82.14 ± 6.18) mL in group A and (149.24 ± 11.17) mL in group B. Length of hospital stay was (7.0 ± 2.1) days in group A and (12.0 ± 2.6) days in group B. Significant difference was noted between two groups in terms of the above parameters (P lt; 0.01). All the wounds healed by first intention. The patients were followed up for 13-54 months (average 27 months) in group A and 12-55 months (average29 months) in group B. Four patients in each group suffered from spinal dural rupture during operation and recovered after corresponding treatment. Three patients in group B had lumbar instabil ity 3 years after operation and recovered using lumbar interbody fusion combined with general spine system internal fixation. No such compl ications as wrong orientation, nerve root injury, cauda equina injury and infection occurred in each group, and radiology exam showed no relapse. Therapeutic effect was evaluated by Nakai standard, 52 cases in group A were graded as excellent, 45 as good, 7 as fair, 1 as poor, and the excellent and good rate was 92.4%; 53 cases in group B were graded as excellent, 48 as good, 8 as fair, 1 as poor, and the excellent and good rate was 91.8%; there was no significant difference between two groups (P gt; 0.05). Conclusion Two methods have the similar therapeutic effect, but MED el iminates the shortcomings of traditional OD, so it is one of ideal minimally invasive operative approaches for degenerative lumbar spinal stenosis.

Two months later, choledochoscopy revealed multiple choledocholithiasis, then the holmium laser lithotripsy and bile duct stent placement was performed at the secondary admission, the postoperative recovery was good, it had been more than 2 months after the surgery, no stone recurrence occurred.ConclusionEndoscopic reverse biliary tract stent placement via choledochus is feasible, which can be used as an option for treatment of patient with situs inversus totalis complicated with choledocholithiasis.
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 systematically evaluate the reliability and stability of transoral endoscopic thyroidectomy vestibular approach (TOETVA) and conventional open thyroidectomy (COT) in the treatment of differentiated thyroid cancer.MethodsThe clinical studies of TOETVA and COT in the treatment of differentiated thyroid cancer were retrieved from major databases including PubMed, Embase, Cochrane Library, Wanfang, and CNKI by computer. The search date ended on March 1, 2020. Two investigators screened the literatures strictly and extracted the data following the pre-defined inclusion and exclusion criteria, and then used RevMan 5.3 software for meta-analysis.ResultsA total of 7 studies including 1 465 patients were included in this meta-analysis. The results showed: compared with the COT group, the operation time of the TOETVA group was longer [WMD=35.18, P=0.000 1], and the number of lymph node dissections in the central area was larger [WMD=1.42, P=0.000 5]. But the intraoperative blood loss [WMD=–5.32, P=0.39], the length of hospital stay after operation [WMD=0.05, P=0.94], the incidences of transient recurrent laryngeal nerve palsy [OR=0.81, P=0.43], transient hypocalcemia [OR=0.55, P=0.35], permanent hypocalcemia [OR=0.39, P=0.22], permanent recurrent laryngeal nerve palsy [OR=1.34, P=0.73], and hematoma [OR=1.29, P=0.69] were not statistically significant between the two groups.ConclusionsTOETVA has a higher stability. Although the COT has a shorter operation time, the former has a higher central lymph node dissection rate, and there is no scar on the neck after surgery and no significant difference in the incidence of postoperative complications.
