Comparative effectiveness of simultaneous and staged operations in patients with atherosclerotic lesions of carotid and coronary arteries

Objective: comparative systematic analysis of clinical trials of staged and simultaneous approaches in the surgical treatment of combined carotid and coronary stenosis based on the literature search.Material and methods. A systematic literature search was performed in PubMed/MEDLINE, Google Scholar and Scopus using predefined acceptance criteria. To compare data of simultaneous and staged surgery cumulative indicators of heart attack, stroke and mortality, expressed as percentages and absolute numbers, were analyzed; the Mantel–Hensel formula and the χ2 method were used to assess the relative risk of major adverse cardio-cerebral events development and mortality.Results. The analysis included 7 studies containing one intervention (4 simultaneous and 3 stage methods). The risk of developing myocardial infarction was RR 0.13 (95% CI 0.02–0.67) for simultaneous tactics, and RR 7.79 (95% CI 1.5–40.43) for staged tactics (p˂0.005). The risk of stroke developing was RR 1.29 (95% CI 0.56–2.99) for a simultaneous approach, and RR 0.78 (95% CI 0.33–1.8) for stage approach (p˃0.05). The risk of mortality was RR 0.77 (95% CI 0.31–1.88) for simultaneous procedures, and RR 1.3 (95% CI 0.53–3.18) for staged procedures (p˃0.05).Conclusion. Staged tactics for combined carotid and coronary stenosis may be accompanied by a significantly higher risk of myocardial infarction. There was no statistically significant difference between the groups in terms of the risk of stroke and mortality, but there was a trend towards a higher risk of stroke in the simultaneous group and a higher risk of death from all causes in the staged group.

The safety and feasibility of the simultaneous use of 180-W GreenLight laser for prostate vaporization during concomitant surgery

Objectives: To explore the safety and feasibility of photo-selective vaporization of the prostate (PVP) with GreenLight XPS 180 Watt laser (GL-180- W XPS) combined with other surgical procedures. Material and methods: Data on patients in whom GL-180-W XPS was performed to relieve lower urinary tract symptoms/ benign prostatic hyperplasia (LUTS/BPH) symptoms were extracted from a multi-institutional database (2011-2016). Patients were stratified into two groups. In the first all patients who had GL-180-W XPS with a concomitant procedure during the same surgical session were included as cases while those who underwent GL-180-W XPS PVP only were included as control. Results: A total of 487 patients were included. Fifty-eight (11.9%) patients underwent concomitant procedures. Multivariable linear regression models failed to find an association between concomitant procedures and longer laser time (p = 0.4). Similarly, multivariable linear regression models failed to find an association between concomitant procedures and laser time even when the analyses were repeated and stratified into endoscopic (p = 0.6) and open/laparoscopic (p = 0.4) procedures. Multivariable logistic regression models failed to demonstrate any association between concomitant procedures and early complications (OR:1.39, CI: 0.379-2.44, p = 0.2), late complications (OR:1.84, CI:0.78-3.98; p = 0.1) and acute urinary retention (OR:1.84, CI:0.78-3.98; p = 0.1). When the analyses were repeated and the concomitant procedures stratified into endoscopic and open/laparoscopic ones, they yielded virtually the same results. Conclusions: GL-180-W XPS PVP could be safely performed in concomitant endoscopic or open/laparoscopic surgery. These results should be taken into consideration in the counseling of the patient who might choose to undergo simultaneous procedures.

However, it is not clear whether this is due to increased recognition of isolated SLAP tears or increased SLAP repair performed secondarily during arthroscopy for other purposes. Hypothesis/Purpose. We hypothesized that both isolated SLAP repair and secondary SLAP repair increased with time and that patient age influenced the pathway to SLAP diagnosis and surgery—such that younger patients were more likely to have isolated SLAP repair surgery after being diagnosed in clinic. Study Design. Descriptive epidemiology study. Methods. Data were obtained from the MarketScan database from 2003 to 2013. CPT and ICD-9 codes were used to identify SLAP surgery patients and concomitant procedures. The timing of SLAP diagnosis relative to surgery was used to determine whether the injury was recognized preoperatively. Results. 64,497 SLAP surgery patients were included. Preoperative SLAP diagnosis increased from 17.1% in 2003 to 44.6% in 2013. Patients diagnosed preoperatively were younger and had fewer concomitant procedures. Increasing age and concomitant rotator cuff tear (RCT) repair corresponded to lower odds of preoperative SLAP diagnosis. Discussion. Younger patients were more likely to have their SLAP tear diagnosed prior to surgery. Those diagnosed before surgery had fewer simultaneous procedures during their operations, suggesting that SLAP repair was more likely the primary operation. From 2003 to 2013, SLAP tears were increasingly recognized in the preoperative setting.

Comparison of Direct Surgical Costs for Proximal Row Carpectomy and Four-Corner Arthrodesis

Background Proximal row carpectomy (PRC) and four-corner arthrodesis (FCA) are common treatments for stage II scapholunate advanced collapse (SLAC) and scaphoid nonunion advanced collapse (SNAC) wrists, with similar functional and patient-reported outcomes reported in the peer-reviewed literature. Questions Study questions included (1) whether surgical encounter total direct costs (SETDCs) differ between PRC and FCA, and (2) whether SETDC differs by method of fixation for FCA. Patients and Methods Consecutive adult patients (≥ 18 years) undergoing PRC and FCA between July 2011 and May 2017 at a single tertiary care academic institution were identified. Patients undergoing additional simultaneous procedures were excluded. Using our institution's information technology value tools, we extracted prospectively collected cost data for each surgical encounter. SETDCs were compared between PRC and FCA, and between FCA subgroups (screws, plating, or staples). Results Of 42 included patients, mean age was similar between the 23 PRC and 19 FCA patients (51.2 vs. 54.5 years, respectively). SETDCs were significantly greater for FCA than PRC by 425%. FCA involved significantly greater facility costs (2.3-fold), supply costs (10-fold), and operative time (121 vs. 57 minutes). Implant costs were absent for PRC, which were responsible for 55% of the SETDC for FCA. Compared with compression screws, plating and staple fixation were significantly more costly (70% and 240% greater, respectively). Conclusion SETDCs were 425% greater for FCA than PRC. Implant costs for FCA alone were 130% greater than the entire surgical encounter for PRC. For FCA, SETDC varied depending on the method of fixation. Level of Evidence This is a level III, cost analysis study.

Absence of Complications after Endoscopic Mucosal Biopsy

Background: There is no clarity with regard to the occurrence of serious complications from EGD-driven mucosal biopsy. This is important for considering both clinically indicated procedures and mucosal sampling for research. Methods: We sought to quantify rates of serious complications from esophagogastroduodenoscopy (EGD) with biopsy. We studied 13,233 patients undergoing outpatient EGD with biopsy over 5 years in 2 North Dakota community hospitals, based on the reasoning that serious complications would cause hospitalization within 30 days. We reviewed the records of all patients with a diagnostic or procedure code or admission within 30 days after the outpatient EGD with biopsy. Results: Of the 13,233 patients who underwent outpatient EGD with biopsy, 411 were admitted within 30 days, most of them because of their underlying diagnosis. Two patients were admitted due to complications that resulted because of additional simultaneous procedures. No patient was admitted because of complications that could be ascribed to conscious sedation, upper GI endoscopic access, or mucosal biopsy. Conclusions: These data confirm that EGD biopsy is safe within community settings and suggest that the risk/benefit ratio for performing EGD biopsy for research is likely to be favorable if the research has scientific merit. Serious complications or perforation following EGD biopsy did not occur in 13,233 patients in community hospitals in North Dakota.

Full Robotic Colorectal Resections for Cancer Combined With Other Major Surgical Procedures: Early Experience With the da Vinci Xi

Background. The da Vinci Xi has been developed to overcome some of the limitations of the previous platform, thereby increasing the acceptance of its use in robotic multiorgan surgery. Methods. Between January 2015 and October 2015, 10 patients with synchronous tumors of the colorectum and others abdominal organs underwent robotic combined resections with the da Vinci Xi. Trocar positions respected the Universal Port Placement Guidelines provided by Intuitive Surgical for “left lower quadrant,” with trocars centered on the umbilical area, or shifted 2 to 3 cm to the right or to the left, depending on the type of combined surgical procedure. Results. All procedures were completed with the full robotic technique. Simultaneous procedures in same quadrant or left quadrant and pelvis, or left/right and upper, were performed with a single docking/single targeting approach; in cases of left/right quadrant or right quadrant/pelvis, we performed a dual-targeting operation. No external collisions or problems related to trocar positions were noted. No patient experienced postoperative surgical complications and the mean hospital stay was 6 days. Conclusions. The high success rate of full robotic colorectal resection combined with other surgical interventions for synchronous tumors, suggest the efficacy of the da Vinci Xi in this setting.

Mass Balance Reconciliation for Bilinear Systems: A Case Study of a Raw Mill Separator in a Typical Moroccan Cement Plant

Stream flow rates and their several compositions are measured in a typical cement raw mill separator. In order to simultaneously reconcile flow and composition measurements in this circuit, the component mass balances was included as constraints which contain the products of flow rate and composition variables in the data reconciliation problem. In this paper, the effectiveness of simultaneous procedures for bilinear data reconciliation is established, the numerical problem constraints were coded in MATLAB and a mass balance model is built. Moreover, based on the difference between the measured and reconciled data it was found that it performs optimally.
