Study Design: Retrospective cohort study. Objective: To investigate radiological differences in lumbar disc herniations (herniated nucleus pulposus [HNP]) between patients receiving microscopic lumbar discectomy (MLD) and nonoperative patients. Methods: Patients with primary treatment for an HNP at a single academic institution between November 2012 to March 2017 were divided into MLD and nonoperative treatment groups. Using magnetic resonance imaging (MRI), axial HNP area; axial canal area; HNP canal compromise; HNP cephalad/caudal migration and HNP MRI signal (black, gray, or mixed) were measured. T test and chi-square analyses compared differences in the groups, binary logistic regression analysis determined odds ratios (ORs), and decision tree analysis compared the cutoff values for risk factors. Results: A total of 285 patients (78 MLD, 207 nonoperative) were included. Risk factors for MLD treatment included larger axial HNP area ( P < .01, OR = 1.01), caudal migration, and migration magnitude ( P < .05, OR = 1.90; P < .01, OR = 1.14), and gray HNP MRI signal ( P < .01, OR = 5.42). Cutoff values for risks included axial HNP area (70.52 mm2, OR = 2.66, P < .01), HNP canal compromise (20.0%, OR = 3.29, P < .01), and cephalad/caudal migration (6.8 mm, OR = 2.43, P < .01). MLD risk for those with gray HNP MRI signal (67.6% alone) increased when combined with axial HNP area >70.52 mm2 (75.5%, P = .01) and HNP canal compromise >20.0% (71.1%, P = .05) cutoffs. MLD risk in patients with cephalad/caudal migration >6.8 mm (40.5% alone) increased when combined with axial HNP area and HNP canal compromise (52.4%, 50%; P < .01). Conclusion: Patients who underwent MLD treatment had significantly different axial HNP area, frequency of caudal migration, magnitude of cephalad/caudal migration, and disc herniation MRI signal compared to patients with nonoperative treatment.

Endoscopic Lumbar Discectomy

Background: Percutaneous endoscopic lumbar discectomy (PELD) is a minimally invasive surgery for the treatment of lumbar disc herniation (LDH) with a smaller incision, decreased damage to soft tissues, faster recovery, and fewer postoperative complications. However, the exactly epidemiological prevalence of recurrent herniation after PELD remains unclear. Objectives: To investigate the epidemiological prevalence of recurrent herniation in patients following PELD and to analyze the potentially related risk factors. Study Design: Meta-analysis and systematic review of prospective and retrospective studies. Methods: We conducted a comprehensive search in MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials that mentioned the incidence of recurrent herniation after PELD. The overall prevalence estimate was calculated by an appropriate meta-analysis. Subgroup analysis, sensitivity analysis, and publication bias assessment were also performed in our study, respectively. Results: Our results showed the overall prevalence of recurrent herniation after PELD was 3.6% (95% CI 3.0-4.3%). The prevalence estimates after percutaneous endoscopic interlaminar discectomy (PEID) and percutaneous endoscopic transforaminal discectomy (PETD) were 4.2% and 3.4%, respectively. Individuals with older age (≥ 50 years) and higher BMI (≥ 25) had increased recurrence rates after PELD than those with younger age (4.3% vs. 2.7%) and normal body mass index (BMI) (4.8% vs. 1.5%). The prevalence was significantly higher at upper discs (5.4%) than that at L4-5 (2.7%) and L5-S1 (3.1%) level. The incidence of recurrent herniation at lateral disc was 4.7%, and the recurrence rate of migrated herniation was 3.8%. In most cases, the recurrent herniation occurred within 6 months postoperatively (accounting for 61.7%). Limitations: A majority of the included articles were relatively low quality retrospective studies with significant heterogeneity among them. Furthermore, owing to the paucity of data focused on recurrence, many potentially predictive factors related to subgroup analyses could not be conducted, which might have influenced the accuracy and comprehensiveness of our meta-analysis. Conclusions: PELD is associated with a certain rate of recurrence (3.6%), which usually occurred within 6 months postoperatively. Older age (≥ 50 years), obesity (BMI ≥ 25), upper lumbar disc and central disc herniation might be independent risk factors for recurrence after PELD; however, different surgical approaches (PETD or PEID), lateral discs, migrated discs and foraminoplasty did not affect the incidence. These factors could be useful in preoperative evaluation, appropriate patient selection and informed consent before PELD.

Background. Pelvic organ prolapse (POP) is a condition in which one or more pelvic organs (consisting of the uterus, vaginal cuff, bladder, intestines, and rectum) or more are still in or out of the vagina. Risk factors that influence the incidence of POP consist of obstetric risk factors (number of parity and birth method) and non-obstetric risk factors (age, menopause, BMI, comorbid disease, and hypertension). The purpose of this study was to analyze the risk factors associated with the degree of POP. Methods. This study is an observational study with a cross-sectional approach to 111 patients examined at the Department of Obstetrics and Gynecology, Dr. Mohammad Hoesin general hospital Palembang on January 2017 to December 2019, who was diagnosed with pelvic organ prolapse. Results. The results showed the effect of variables with the degree of POP using the chi-square test, consisting of parity (p=0.007), birth method (p=<0.001), age (p=0.016), menopause (p=0.001), BMI (p =0.005), indicates that there is a significant effect on the degree of POP. Meanwhile, comorbid factors (p=0.481) and hypertension (p=0.415) did not show a significant relationship with the degree of POP. The results of the binary logistic regression analysis of all risk factors, the number of parity >4, overweight, and age 40 years, will have a 99.85% chance of experiencing grade 3 or 4 prolapse. Conclusion. Age is the most dominant risk factor affecting the degree of pelvic organ prolapse, with 19 times the chance of developing POP 3 or 4 degrees.

Abstract Background Robot-assisted laparoscopic radical prostatectomy ( RALRP) has better effects than conventional laparoscopic radical prostatectomy (LRP). However, limited data is available regarding the incidence and risk factors for developing postoperative delirium in patients undergoing these two procedures. This study aimed to assess the incidence of postoperative delirium in patients undergoing RALRP and LRP, and evaluated the risk factors for developing postoperative delirium Methods From June 2013 to December 2019, 81 cases of RALRP patients and 71 cases of LRP patients were included in this study. The unpaired Student t tests, repetitive measure analysis of variance and chi-square test were used to compare several different parameters. The binary logistic regression analysis was used to explore the independent risk factors of postoperative delirium . Results The incidences of postoperative delirium in group RALRP and LRP were (17.3% VS 32.4%, P = 0.03), IAP was (12.72 ± 1.87 VS 13.37 ± 1.12 mmHg; P = 0.01), PaCO2 at post-pneumoperitoneum and after loosening pneumoperitoneum were (47.89 ± 10.89 VS 38.65 ± 16.32 mmHg; P < 0.001; 40.77 ± 5.34 VS 43.57 ± 4.54 mmHg; P = 0.001), the overall cost was (8.29 ± 5.55 VS 5.18 ± 1.51 Ten thousand RMB, P < 0.001). The incidence of postoperative delirium increased 1.17 times, 1.13 times, and 1.66 times for each unit increase recovery time (Tr), post-pneumoperitoneum PaCO2 and IAP. Conclusion The RALRP group had a lower IAP, lower incidence of postoperative delirium and shorter recovery time compared with the LRP group, but the overall cost was higher. IAP was the main factor affecting the incidence of postoperative delirium.

Common Procedure

Summary Lumbar disc herniation (LDH) is the most common pathology in young people, as well as people of active age. Despite sophisticated and new minimally invasive surgical techniques and approaches, reoperations for recurrent lumbar disc herniation (rLDH) could not be avoided. LDH recurrence rates, reported in different studies, range from 5 to 25%. The purpose of this study was to estimate the recurrence rates of LDH after standard discectomy (SD) and microdiscectomy (MD), and compare them to those reported in the literature. Retrospectively, operative reports for the period 2012-2017 were reviewed on LDH surgeries performed at the Neurosurgery Clinic of Dr Georgi Stranski University Hospital in Pleven. Five hundred eighty-nine single-level lumbar discectomies were performed by one neurosurgeon. The diagnoses of recurrent disc herniation were based on the development of new symptoms and magnetic resonance/computed tomography (MRI/CT) images showing compatible lesions in the same lumbar level as the primary lumbar discectomies. The recurrence rate was determined by using chi-square tests and directional measures. SD was the most common procedure (498 patients) followed by MD (91 patients). The cumulative reoperation rate for rLDH was 7.5%. From a total number of reoperations, 26 were males (59.1%) and 18 were females (40.9%). Reoperation rates were 7.6% and 6.6% after SD and MD respectively. The recurrence rate was not significantly higher for SD. Our recurrence rate was 7.5%, which makes it comparable with the rates of 5-25% reported in the literature.

Objective: This study aimed to evaluate whether neutrophil/lymphocyte (N/L) ratio assists in the diagnosis of coronary artery disease (CAD) in patients with suspected diaphragmatic attenuation artifact (DAA) on myocardial perfusion SPECT (MP-SPECT). Material and Methods: A total of 255 patients undergoing coronary angiography between 2015-2020 due to unclear DAA of the inferior wall on MP-SPECT were included in this retrospective study. Patients were divided into two groups (CAD and non-CAD) according to angiographic images. Significant CAD was defined as ≥50% stenosis of coronary arteries feeding the inferior wall. White blood cell count, biochemical parameters, and risk factors for CAD were compared between the two groups. Results: There was no statistically significant difference between the two groups in terms of age (p = 0.055), gender (p = 0.482), and body mass index (p = 0.305). N/L ratio (OR = 1.397 p = 0.002 95% Cl = 1.128-1.732) and left ventricle ejection fraction (OR = 0.896 p = 0.023 95% Cl = 0.815-0.985) were independent risk factors for CAD in multivariate binary logistic regression analysis. Receiver Operating Characteristic (ROC) curve analysis showed that a cut-off value of ≥2 for N/L ratio predicted the presence of CAD (sensitivity=63.5%, specificity=60.7%, AUC=0.668, 95% CI=0.596 – 0.740, p<0.001). Conclusion: N/L ratio is a simple and accessible test and may increase the diagnostic accuracy of MP-SPECT for CAD in patients with suspicious diaphragmatic attenuation on MP-SPECT.

Abstract Background and aim Post-polypectomy bleeding (PPB) remains an uncommon although serious complication of colonoscopy. The aim of this study is to determine the PPB-prevalence in a secondary care hospital and its associated risk factors. Patients and methods We collected data from 581 patients, with the removal of 1593 polyps between August 2017 and August 2019. A univariate binary logistic regression analysis was conducted retrospectively. Results PPB occurred in only 10 cases, representing 1.7% of patients: immediate in 1.2% and delayed in 0.5%. The number of removed polyps per patient [4.5 (SD 2.59) for hemorrhagic vs. 2.74 (SD 1.98) for non-hemorrhagic group] and the propofol dose [232 mg (SD 93.07) for hemorrhagic vs. 133 mg (SD 57.28) for non-hemorrhagic group] were relevant patient-related risk factors. The polyp-based analysis showed the polyp size [18.4 mm (SD 10.44) for hemorrhagic vs. 4.42 mm (SD 4.29) for non-hemorrhagic group], the morphology [wide-based: OR 24.83 (95 % CI 2.76 – 223.44), pedunculated: OR 56.67 (95 % CI 5.03 – 638.29)], the location at ileocecal valve [OR 20.48, 95 % CI 1.81 – 231.97)], and the polypectomy method [hot snare piecemeal with epinephrine injection: OR 75.38 (95 % CI 7.67 – 741.21)] as significant risk factors for PPB, too. Conclusions The low rate of PPB confirms the safety of the procedure in non-tertiary, high-volume colonoscopy centers. The number of polyps removed per patient, the polyp size, morphology and location, as well as the sedation dose and the method of polypectomy were shown as relevant risk factors.
