Recent studies showed that chronic administration of losartan, an angiotensin II type I receptor antagonist, improved skeletal muscle function in dystrophin-deficient mdx mice. In this study, C57BL/10ScSn-Dmd^mdx/J female mice were either untreated or treated with losartan (n = 15) in the drinking water at a dose of 600 mg/L over a 6-month period. Cardiac function was assessed via in vivo high frequency echocardiography and skeletal muscle function was assessed using grip strength testing, Digiscan monitoring, Rotarod timing, and in vitro force testing. Fibrosis was assessed using picrosirius red staining and Image J analysis. Gene expression was evaluated using real-time polymerized chain reaction (RT-PCR). Percentage shortening fraction was significantly decreased in untreated (26.9% ± 3.5%) mice compared to losartan-treated (32.2% ± 4.2%; P < .01) mice. Systolic blood pressure was significantly reduced in losartan-treated mice (56 ± 6 vs 69 ± 7 mm Hg; P < .0005). Percentage cardiac fibrosis was significantly reduced in losartan-treated hearts (P < .05) along with diaphragm (P < .01), extensor digitorum longus (P < .05), and gastrocnemius (P < .05) muscles compared to untreated mdx mice. There were no significant differences in skeletal muscle function between treated and untreated groups. Chronic treatment with losartan decreases cardiac and skeletal muscle fibrosis and improves cardiac systolic function in dystrophin-deficient mdx mice.

The introduction of robotics in living donor liver transplantation has been revolutionary. We aimed to examine the safety of robotic living donor right hepatectomy (RLDRH) compared to open (ODRH) and laparoscopic (LADRH) approaches. A systematic review was carried out in Medline and six additional databases following PRISMA guidelines. Data on morbidity, postoperative liver function, and pain in donors and recipients were extracted from studies comparing RLDRH, ODRH, and LADRH published up to September 2020; PROSPERO (CRD42020214313). Dichotomous variables were pooled as risk ratios and continuous variables as weighted mean differences. Four studies with a total of 517 patients were included. In living donors, the postoperative total bilirubin level (MD: −0.7 95%CI −1.0, −0.4), length of hospital stay (MD: −0.8 95%CI −1.4, −0.3), Clavien–Dindo complications I–II (RR: 0.5 95%CI 0.2, 0.9), and pain score at day > 3 (MD: −0.6 95%CI −1.6, 0.4) were lower following RLDRH compared to ODRH. Furthermore, the pain score at day > 3 (MD: −0.4 95%CI −0.8, −0.09) was lower after RLDRH when compared to LADRH. In recipients, the postoperative AST level was lower (MD: −0.5 95%CI −0.9, −0.1) following RLDRH compared to ODRH. Moreover, the length of stay (MD: −6.4 95%CI −11.3, −1.5) was lower after RLDRH when compared to LADRH. In summary, we identified low- to unclear-quality evidence that RLDRH seems to be safe and feasible for adult living donor liver transplantation compared to the conventional approaches. No postoperative deaths were reported.

Background: Postoperative leaks develop in a low percentage of patients undergoing laparoscopic sleeve gastrectomy (LSG), representing a rare yet devastating postoperative complication increasing morbidity and hospital stay. Leaks can become collections and may be very difficult to manage. Several therapeutic options with variable results, including surgical and nonsurgical methods have been described. Endoscopic abscess septotomy is an alternative method recently performed by a few centers reporting efficacy and safety outcomes. The purpose of this report is to present our successful experience with endoscopic abscess septotomy for the treatment of postsleeve gastrectomy leaks. Methods: Two female patients with post-LSG leaks and abscess formation diagnosed 4 weeks postprocedure, initially managed with diagnostic laparoscopy, peritoneal washout, and drain placement with poor improvement, were chosen for endoscopic abscess septotomy with concomitant lumen dilation and sleeve axis rectification. Results: Endoscopic abscess septotomy was successfully performed in both patients with no complications. Clinical and radiological resolutions were accomplished at 10 and 12 weeks, respectively, postseptotomy. Conclusion: This endoscopic approach is a feasible and effective method for the treatment of leaks and collections after LSG. Concomitant balloon dilation of the gastric sleeve improves gastric emptying and reduces intraluminal pressure, hence favoring tissue healing and leak resolution.
