METHODS: A 37-item questionnaire-based survey was conducted to capture the perioperative practices of the global community of bariatric surgeons. Data were analyzed using descriptive statistics.
RESULTS: Response of 863 bariatric surgeons from 67 countries with a cumulative experience of 520,230 SGs were recorded. A total of 689 (80%) and 764 (89%) surgeons listed 13 absolute and relative contraindications, respectively. 65% (n = 559) surgeons perform routine preoperative endoscopy and 97% (n = 835) routinely use intraoperative orogastric tube for sizing the resection. A wide variation is observed in the diameter of the tube used. 73% (n = 627) surgeons start dividing the stomach at a distance of 3-5 cm from the pylorus, and 54% (n = 467) routinely use staple line reinforcement. Majority (65%, n = 565) of surgeons perform routine intraoperative leak test at the end of the procedure, while 25% (n = 218) surgeons perform a routine contrast study in the early postoperative period. Lifelong multivitamin/mineral, iron, vitamin D, calcium, and vitamin B12 supplementation is advocated by 66%, 29%, 40%, 38% and 44% surgeons, respectively.
CONCLUSION: There is a considerable variation in the perioperative practices concerning SG. Data can help in identifying areas for future consensus building and more focussed studies.
METHODS: Patients included had the diagnosis of significant back pain caused by osteoporotic vertebral compression fracture secondary to trivial injury. All the patients underwent routine preoperative sitting lateral spine radiograph, supine stress lateral spine radiograph, and supine anteroposterior spine radiograph. The radiological parameters recorded were anterior vertebral height (AVH), middle vertebral height (MVH), posterior vertebral height (PVH), MVH level below, wedge endplate angle (WEPA), and regional kyphotic angle (RKA). The supine stress versus sitting difference (SSD) for all the above parameters were calculated.
RESULTS: A total of 28 patients (4 males; 24 females) with the mean age of 75.6 ± 7.7 years were recruited into this study. The mean cement volume injected was 5.5 ± 1.8 ml. There was no difference between supine stress and postoperative radiographs for AVH ( p = 0.507), PVH ( p = 0.913) and WEPA ( p = 0.379). The MVH ( p = 0.026) and RKA ( p = 0.005) were significantly less in the supine stress radiographs compared to postoperative radiographs. There was significant correlation ( p < 0.05) between supine stress and postoperative AVH, MVH, PVH, WEPA, and RKA. The SSD for AVH, PVH, WEPA, and RKA did not have significant correlation with the cement volume ( p > 0.05). Only the SSD-MVH had significant correlation with cement volume, but the correlation was weak ( r = 0.39, p = 0.04).
CONCLUSIONS: Dynamic mobility stress radiographs can predict the postoperative vertebral height restoration and kyphosis correction after vertebroplasty for thoracolumbar osteoporotic fracture with intravertebral clefts. However, it did not reliably predict the amount of cement volume injected as it was affected by other factors.
MATERIALS AND METHODS: A prospective cohort study, 139 women, underwent transvaginal surgery for anterior and/or apical POP > stage 2, 69 patients had SIM A and 70 patients had SSF. The objective cure was defined as POP ≤ stage 1 anterior, apical according to POP-Q. Subjective cure is patient's negative feedback to question 2 and 3 of pelvic organ prolapse distress inventory 6 (POPDI-6). Patient's satisfaction was reported using validated quality of life questionnaires. Multi-channel urodynamic study was used to report any voiding problems related to the prolapse surgery 6 months after surgery.
RESULTS: 119 patients completed a minimum of 3 years follow-up. 89.8% is the overall prolapse correction success rate for SIM A and 73.3% for SSF group (p = 0.020), and 96.6% versus 73.4% at the anterior vaginal compartment respectively (p ≤ 0.001). Statistically significant difference was noticed in apical compartment with 98.3% with SIM A and 85.0% with SSF (p = 0.009). The subjective success rate, 86.4% in the SIM A and 70.0% in the SSF arm (p = 0.030) was significantly noted. Only, Pelvic Organ Prolapse Distress Inventory-6 (POPDI-6) showed significant improvement. Operation time and intra-operative blood loss tend to be more with SIM A.
CONCLUSION: SIM A has better 3 years objective and subjective cure rate than SSF in the anterior and/or apical compartment prolapse.
METHODS: Patients aged 75 years and older who underwent bariatric procedures in two academic centers between 2006 and 2015 were studied.
RESULTS: A total of 19 patients aged 75 years and above were identified. Eleven (58%) were male, the median age was 76 years old (range 75-81), and the median preoperative body mass index (BMI) was 41.4 kg/m2 (range 35.8-57.5). All of the bariatric procedures were primary procedures and performed laparoscopically: sleeve gastrectomy (SG) (n = 11, 58%), adjustable gastric band (AGB) (n = 4, 21%), Roux-en-Y gastric bypass (RYGB) (n = 2, 11%), banded gastric plication (n = 1, 5%), and gastric plication (n = 1, 5%). The median operative time was 120 min (range 75-240), and the median length of stay was 2 days (range 1-7). Three patients (16%) developed postoperative atrial fibrillation which completely resolved at discharge. At 1 year, the median percentage of total weight loss (%TWL) was 18.4% (range 7.4-22.0). The 1-year %TWL varied among the bariatric procedures performed: SG (21%), RYGB (22%), AGB (7%), and gastric plication (8%). There were no 30-day readmissions, reoperations, or mortalities.
CONCLUSION: Our experience suggests that bariatric surgery in selected patients aged 75 years and older would be safe and effective despite being higher risk. Age alone should not be the limiting factor for selecting patients for bariatric surgery.
METHODS: Planned analysis of data was collected during an international 7-day cohort study of adults undergoing elective in-patient surgery. AKI was defined using Kidney Disease Improving Global Outcomes criteria. Patients missing preoperative creatinine data were excluded. We used multivariable logistic regression to examine the relationships among preoperative creatinine-based estimated glomerular filtration rate (eGFR), postoperative AKI, and hospital mortality, accounting for the effects of age, major comorbid diseases, and nature and severity of surgical intervention on outcomes. We similarly modeled preoperative associations of AKI. Data are presented as n (%) or odds ratios (ORs) with 95% confidence intervals.
RESULTS: A total of 36,357 patients were included, 743 (2.0%) of whom developed AKI with 73 (9.8%) deaths in hospital. AKI affected 73 of 196 (37.2%) of all patients who died. Mortality was strongly associated with the severity of AKI (stage 1: OR, 2.57 [1.3-5.0]; stage 2: OR, 8.6 [5.0-15.1]; stage 3: OR, 30.1 [18.5-49.0]). Low preoperative eGFR was strongly associated with AKI. However, in our model, lower eGFR was not associated with increasing mortality in patients who did not develop AKI. Conversely, in older patients, high preoperative eGFR (>90 mL·minute·1.73 m) was associated with an increasing risk of death, potentially reflecting poor muscle mass.
CONCLUSIONS: The occurrence and severity of AKI are strongly associated with risk of death after surgery. However, the relationship between preoperative renal function as assessed by serum creatinine-based eGFR and risk of death dependent on patient age and whether AKI develops postoperatively.
METHOD: This international multi-center prospective study across 137 hospitals in 41 countries included patients who underwent an esophagectomy for esophageal cancer, with 90-day follow-up. The main explanatory variable was country income, defined according to the World Bank Data classification. The primary outcome was 90-day postoperative mortality, and secondary outcomes were composite leaks (anastomotic leak or conduit necrosis) and major complications (Clavien-Dindo Grade III - V). Multivariable generalized estimating equation models were used to produce adjusted odds ratios (ORs) and 95% confidence intervals (CI95%).
RESULTS: Between April 2018 to December 2018, 2247 patients were included. Patients from HIC were more significantly older, with higher ASA grade, and more advanced tumors. Patients from LMIC had almost three-fold increase in 90-day mortality, compared to HIC (9.4% vs 3.7%, p
