RRC may ensure limited improvements in post-operative outcome, thus increasing procedural costs and without a proved enhanced oncological accuracy to date, if compared to the LRC.
HighlightsUrachal remnant anomalies are uncommon in adulthood.Surgical removal of urachal remnants is indicated to prevent recurrent infection.Urachal carcinoma is a rare but aggressive cancer.Laparoscopic approach represents the safest approach to remove urachal remnant.
LRYGB resulted associated with higher post-operative morbidity rate and increased 1-year EWL than LSG. Prospective studies are needed to assess the impact of these two surgical procedures on the long-term weigh loss.
Internal hernia (IH) is a severe complication after laparoscopic Roux-en-Y gastric bypass. The orientation of the alimentary limb has advocated to affect IH. Available data regarding the incidence of IH, gastro-jejunostomy leakage, obstructive symptoms, anastomotic obstruction, adhesion, incisional hernia, total complications, and recurrent IH were meta-analyzed according to the orientation of the alimentary limb. Fourteen studies (13,660 patients) were included. Antecolic orientation resulted associated with a lower incidence of IH and obstructive symptoms, while the route of the alimentary limb did not show to affect the other outcomes. Antecolic orientation decreases the IH. However, the role and the technique of the closure of mesenteric defects cannot be stated due to the lack of adequate data to date. Well-designed randomized controlled trials (RCTs) are needed.
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.
