mon and potentially lethal disorder. 1 In the United States alone, more than 50 000 patients are admitted with acute pancreatitis each year. 2 One of the most dreaded complications in these patients is infected necrotizing pancreatitis that leads to sepsis and is often followed by multiple organ failure. 3 In these patients interventions are necessary to debride the infected necrosis, but the interventions themselves cause substantial morbidity. 4-6 The treatment of infected necrotizing pancreatitis has undergone fundamental changes in recent years. Whenever possible, intervention is postponed until the collections with necrosis are demarcated. 7,8 Demarcation facilitates necrosectomy and reduces complications related to the drainage and debride-ment procedures. 9 A recent randomized trial demonstrated that a step-up approach of percutaneous catheter For editorial comment see p 1084.
Objectives To determine the best approach for live donor nephrectomy to minimise discomfort to the donor and to provide good graft function. Design Single blind, randomised controlled trial. Setting Two university medical centres, the Netherlands. Participants 100 living kidney donors. Interventions Participants were randomly assigned to either laparoscopic donor nephrectomy or to mini incision muscle splitting open donor nephrectomy. Main outcome measures The primary outcome was physical fatigue using the multidimensional fatigue inventory 20 (MFI-20). Secondary outcomes were physical function using the SF-36, hospital stay after surgery, pain, operating times, recipient graft function, and graft survival. Results Conversions did not occur. Compared with mini incision open donor nephrectomy, laparoscopic donor nephrectomy resulted in longer skin to skin time (median 221 v 164 minutes, P < 0.001), longer warm ischaemia time (6 v 3 minutes, P < 0.001), less blood loss (100 v 240 ml, P < 0.001), and a similar number of complications (intraoperatively 12% v 6%, P = 0.49, postoperatively both 6%). After laparoscopic nephrectomy, donors required less morphine (16 v 25 mg, P = 0.005) and shorter hospital stay (3 v 4 days, P = 0.003). During one year's follow-up mean physical fatigue was less (difference − 1.3, 95% confidence interval − 2.4 to − 0.1) and physical function was better (difference 6.2, 2.0 to 10.3) after laparoscopic nephrectomy. Function of the graft and graft survival rate of the recipient at one year censored for death did not differ (100% after laparoscopic nephrectomy and 98% after open nephrectomy). Conclusions Laparoscopic donor nephrectomy results in a better quality of life compared with mini incision open donor nephrectomy but equal safety and graft function.
LTF reduces postoperative dysphagia and dilatation for dysphagia compared with LNF. Reoperation rate and prevalence of gas-related symptoms were lower after LTF, with similar reflux control. These results provide level 1a support for the use of LTF as the posterior fundoplication of choice for GORD.
Hiatal hernia (HH) is an infrequent yet potentially life-threatening complication after esophagectomy. Several studies have reported the incidence of this complication after both open and minimally invasive esophagectomy (MIE). This meta-analysis aimed to determine the pooled incidence of HH after both types of esophagectomy and, importantly, to provide insight in the outcome of subsequent HH repair. A systematic search was performed of the PubMed, Embase, CINAHL, and Cochrane databases. Article selection was performed using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria. Articles describing the incidence of HH after different open and minimally invasive techniques were included. Only when five or more comparable studies reported on the same outcome were data pooled. The incidence of postoperative HH and the outcome of HH repair were analyzed. Twenty-six studies published between 1985 and 2015 were included, describing a total of 6058 patients who underwent esophagectomy, of whom 240 were diagnosed with a postoperative HH. The pooled incidence of symptomatic HH after MIE was 4.5 %, compared to a pooled incidence of 1.0 % after open esophagectomy. 11 studies reported on the outcome of HH repair in 125 patients. A pooled morbidity rate after HH repair of 25 % was found. During follow-up, a pooled recurrence rate of 14 % was reported in 11 of the included studies. The pooled incidence of HH after MIE is higher compared to open esophagectomy. Most importantly, surgical repair of these HHs is associated with a high morbidity rate. Both radiologists and surgeons should be aware of this rare yet potentially life-threatening complication.
This study shows that cefazolin tissue distribution is lower in morbidly obese patients and reduces with increasing body weight, and that dose adjustments are required in this patient group.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
