AIMTo identify which technique is better for avoiding biliary reflux and gastritis between uncut Roux-en-Y and Billroth II reconstruction.METHODSA total of 158 patients who underwent laparoscopy-assisted distal gastrectomy for gastric cancer at the First Hospital of Jilin University (Changchun, China) between February 2015 and February 2016 were randomized into two groups: uncut Roux-en-Y (group U) and Billroth II group (group B). Postoperative complications and relevant clinical data were compared between the two groups.RESULTSAccording to the randomization table, each group included 79 patients. There was no significant difference in postoperative complications between groups U and B (7.6% vs 10.1%, P = 0.576). During the postoperative period, group U stomach pH values were lower than 7 and group B pH values were higher than 7. After 1 year of follow-up, group B presented a higher incidence of biliary reflux and alkaline gastritis. However, histopathology did not show a significant difference in gastritis diagnosis (P = 0.278), and the amount of residual food and gain of weight between the groups were also not significantly different. At 3 mo there was no evidence of partial recanalization of uncut staple line, but at 1 year the incidence was 13%.CONCLUSIONCompared with Billroth II reconstruction, uncut Roux-en-Y reconstruction is secure and feasible, and can effectively reduce the incidence of alkaline reflux, residual gastritis, and heartburn. Despite the incidence of recanalization, uncut Roux-en-Y should be widely applied.
Background: Adult intussusception is less common than paediatric intussusception. The aim of this study was to explore the clinical presentation, aetiology, diagnosis and treatment of adult intussusception. Methods: Adults (>18 years) with intussusception treated by surgical or conservative measures were included from January 2005 to January 2018, and the manifestation, types, diagnosis and treatment of adult intussusception in our centre were reviewed. Results: A total of 150 patients with adult intussusception were included in this study. The clinical manifestations included 111 cases (74%) of abdominal pain, 38 cases (25.3%) of bloody stool, 37 cases (24.7%) of bowel obstructions, 33 cases (22%) of abdominal distension, 29 cases (19.3%) of nausea and vomiting, 19 cases (12.7%) of an abdominal mass, and 12 cases (8.0%) of diarrhoea. The types of intussusception were classified into 36 cases (24%) of enteric intussusception, 87 cases (58%) of intestine-colon intussusception and 27 cases (18%) of colonic intussusception. Surgical intervention was applied in 139 cases (92.7%), including 115 patients who underwent open surgery, and laparoscopy-assisted surgery was performed in 24 patients. The main pathogenesis of intussusception was malignant tumors in 51 cases (36.7%) and benign tumors and polyps in 49 cases (35.3%). Conclusion: Malignant and benign tumors are the main causes of adult intussusception. Abdominal CT is the preferred evaluation method for the preoperative diagnosis of this condition. The choice of surgical procedure depends on the location and type of intussusception.
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.
