Decompressing Stoma as Bridge to Elective Surgery is an Effective Strategy for Left-sided Obstructive Colon Cancer:A National, Propensity-score Matched Study
OBJECTIVE: The purpose of this population-based study was to compare decompressing stoma (DS) as bridge to surgery (BTS) with emergency resection (ER) for left-sided obstructive colon cancer (LSOCC) using propensity-score matching. SUMMARY BACKGROUND DATA: Recently, an increased use of DS as BTS for LSOCC has been observed in the Netherlands. Unfortunately, good quality comparative analyses with ER are scarce. METHODS: Patients diagnosed with nonlocally advanced LSOCC between 2009 and 2016 in 75 Dutch hospitals, who underwent DS or ER in the curative setting, were propensity-score matched in a 1:2 ratio. The primary outcome measure was 90-day mortality, and main secondary outcomes were 3-year overall survival and permanent stoma rate. RESULTS: Of 2048 eligible patients, 236 patients who underwent DS were matched with 472 patients undergoing ER. After DS, more laparoscopic resections were performed (56.8% vs 9.2%, P < 0.001) and more primary anastomoses were constructed (88.5% vs 40.7%, P < 0.001). DS resulted in significantly lower 90-day mortality compared to ER (1.7% vs 7.2%, P = 0.006), and this effect could be mainly attributed to the subgroup of patients over 70 years (3.5% vs 13.7%, P = 0.027). Patients treated with DS as BTS had better 3-year overall survival (79.4% vs 73.3%, hazard ratio 0.36, 95% confidence interval 0.20-0.65) and fewer permanent stomas (23.4% vs 42.4%, P < 0.001). CONCLUSIONS: In this nationwide propensity-score matched study, DS as a BTS for LSOCC was associated with lower 90-day mortality and better 3-year overall survival compared to ER, especially in patients over 70 years of age
Late outcomes comparison of nonelderly patients with stented bioprosthetic and mechanical valves in the aortic position: A propensity-matched analysis
ObjectiveOur study compares late mortality and valve-related morbidities between nonelderly patients (aged <65 years) undergoing stented bioprosthetic or mechanical valve replacement in the aortic position.MethodsWe identified 1701 consecutive patients aged <65 years who underwent aortic valve replacement between 1992 and 2011. A stented bioprosthetic valve was used in 769 patients (45%) and a mechanical valve was used in 932 patients (55%). A stepwise logistic regression propensity score identified a subset of 361 evenly matched patient-pairs. Late outcomes of death, reoperation, major bleeding, and stroke were assessed.ResultsFollow-up was 99% complete. The mean age in the matched cohort was 53.9 years (bioprosthetic valve) and 53.2 years (mechanical valve) (PÂ =Â .30). Fifteen additional measurable variables were statistically similar for the matched cohort. Thirty-day mortality was 1.9% (bioprosthetic valve) and 1.4% (mechanical valve) (PÂ =Â .77). Survival at 5, 10, 15, and 18 years was 89%, 78%, 65%, and 60% for patients with bioprosthetic valves versus 88%, 79%, 75%, and 51% for patients with mechanical valves (PÂ =Â .75). At 18 years, freedom from reoperation was 95% for patients with mechanical valves and 55% for patients with bioprosthetic valves (PÂ =Â .002), whereas freedom from a major bleeding event favored patients with bioprosthetic valves (98%) versus mechanical valves (78%; PÂ =Â .002). There was no difference in stroke between the 2 matched groups.ConclusionsIn patients aged <65 years, despite an increase in the rate of reoperation with stented bioprosthetic valves and an increase in major bleeding events with mechanical valves, there is no significant difference in mortality at late follow-up
Panorametry: suggestion of a method for mandibular measurements on panoramic radiographs
<p>Abstract</p> <p>Background</p> <p>Orthopantomography (panoramic radiography) has been used for the study of measurements involving particularly the prediction of the eruption of impacted lower third molars and analyses of measurements of the ramus and head of mandible. The discrepancies involved with the projection of this radiographic image has stimulated the search for further ways to use it, particularly in orthodontic treatments and oral and maxillofacial surgeries. The author proposes a graphimetric method for the mandible, based on panoramic radiography. The results are expressed in linear and angular measurements, aiming at bilateral comparisons as well as the determination of the proportion of skeletal and dental structures, individually and among themselves as a whole. The method has been named Panorametry, and allows measurement of the mandible (Mandibular Panorametry) or the posterior mandibular teeth (Dental Panorametry). When combining mandible and maxilla, it should be referred to as Total Panorametry. It may also be used, in the future, with Cone Beam computed tomography (CT) images, and in this case it may be mentioned as CT Panorametry.</p
