“…CT results because tests were not conducted on a routine basis. Accordingly, diagnostic differences between our study and previous studies that used CT and PFT may have resulted in a higher reported incidence of atelectasis (45.2% vs. 37.84% and 13.49%) [4,25].…”

Purpose: To compare the prophylactic effects of postoperative continuous positive airway pressure (CPAP) therapy plus conventional postoperatively pulmonary physiotherapy (CPP) and postoperative CPP alone on the development of pulmonary atelectasis after laparoscopic Roux-en-Y gastric bypass (LGBP) in obese patients. Materials and Methods: Patients with BMIs＞27.5 kg/m 2 aged between 20 and 65 years were enrolled in the present study. All subjects received LGBP and were divided into 2 groups. Patients in the CPAP group received both CPAP and CPP therapy postoperatively, and patients in the conventional group received CPP alone. The primary outcome was the incidence of postoperative pulmonary atelectasis as determined by chest X-ray after LGBP, and the secondary outcome was duration of postoperative hospital stay (HS). Results: Seventy-three patients were enrolled in this study. Fifty-seven patients received CPAP plus CPP, and 16 patients received CPP. The CPAP group had an atelectasis incidence of 40.4% (23/57) and the conventional group an incidence of 62.5% (10/16). Multivariate analysis showed the incidence of atelectasis after LGBP was significantly lower in the CPAP group (OR 0.198, 95% CI 0.045-0.874; P=0.033) and that HS was significantly correlated with the developments of atelectasis, pneumonia, and complications (partial correlation coefficients 0.271, 0.444 and 0.382; P-values 0.025, ＜0.05 and ＜0.05, respectively). Conclusion: Patients that received continuous positive airway pressure therapy plus conventional pulmonary physiotherapy postoperatively were at significantly less risk of developing pulmonary atelectasis after LGBP than patients that received conventional pulmonary physiotherapy postoperatively.

“…We acknowledge that the cost of this extra imaging increases the cost of our stapleless technique; however, we felt that it was warranted in our initial series to be skeptical. Although our patients were closely monitored for clinical signs of early leak such as tachycardia, fever, and unequal inspiration [ 7 ], we note that these signs are not specific to leakage and could indicate atelectasis, which is recognized as the most common complication in bariatric patients [ 32 ]. Dehydration also causes low-grade pyrexia and tachycardia and could have confounded the diagnosis of an early leak.…”

Stapleless Laparoscopic Sleeve Gastrectomy: Reasoning and Technical Insights

BackgroundLaparoscopic sleeve gastrectomy (LSG) with staple line reinforcement (SLR) is a popular and safe treatment option for morbid obesity. We have developed, devised, and described our own method of stapleless laparoscopic sleeve gastrectomy, which in our limited study appeared safe, efficacious, and potentially cost-effective.MethodsWe analyzed the outcome of our modified LSG in a case series of three middle-aged women (median age 42 years old). Our main modification was sutured closure of the stomach rather than the commonly utilized technique of stapled closure. Our primary measure of success was the occurrence of post-operative leak. Secondary measures were (a) length of operation, (b) duration of inpatient stay, and (c) percentage of weight loss at 6 and 12 months post operation.ResultsMedian operative time = 132 min (120–195 min), and median inpatient stays were 2 days. No post-operative leaks were recorded. The median excess weight loss at 6 months was 39% of initial weight loss and 57.7% at 12 months.ConclusionsStapleless LSG has the potential to be an affordable alternative to the traditional LSG. High-powered studies and a formal cost analysis are required.

“…[4–6] It has been estimated that the incidence of atelectasis is 90% in patients receiving general anesthesia. [7–10] This condition consists of obstructive, nonobstructive, postoperative, and rounded atelectasis. [11] Several factors are responsible for this disorder, including compressive atelectasis, resorptive atelectasis, and impaired lung surfactant production or function.…”

View full text Add to dashboard Cite

Background:This study aims to assess the efficacy and safety of ventilator for the treatment of atelectasis.Methods:We will search Cochrane Library, MEDLINE, EMBASE, CINAHL, EBSCO, Chinese database Chinese Biomedical Literature Database, China National Knowledge Infrastructure, and Wanfang data from inceptions to June 30, 2019 without language limitations. We will include randomized controlled trials (RCTs) of ventilator on evaluating the efficacy and safety of ventilator for atelectasis. We will use Cochrane risk of bias tool to assess the methodological quality for all included RCTs. RevMan 5.3 software will be used for statistical analysis.Results:The primary outcome is lung function. The secondary outcomes comprise of airway pressure, mean arterial pressure, arterial blood gas, heart rate, respiratory rate, oxygen saturation, and adverse events.Conclusion:The findings of this study will provide most recent evidence of ventilator for the treatment of atelectasis.Systematic review registration:PROSPERO CRD42019139329.
