ObjectiveTo discuss the current status and progress of delayed gastric emptying (DGE) after pancreaticoduodenectomy (PD).MethodThe related researches about DGE after PD in recent year were searched and reviewed.ResultsThe etiology and pathogenesis of DGE had not yet been fully elucidated. There were various risk factors, such as the surgical trauma, advanced age, diabetes, and with other abdominal complications. The pylorus preserving PD didn’t increase the risk of DGE. The pylorus ring resection, anterior colon, Braun anastomosis, and minimally invasive surgery were beneficial for reducing DGE. Although there was no obvious progress in the treatment of DGE at home and abroad, the majority of patients could be cured by the symptomatic conservative treatment.ConclusionsPrevention is a main strategy for DGE after PD. Application of enhanced recovery after surgery might be a key to solve problem in clinical, but further research is needed.
ObjectiveTo analyze the risk factors affecting delayed gastric emptying (DGE) after laparoscopic distal gastrectomy for gastric cancer. MethodsThe gastric cancer patients who underwent laparoscopic distal gastrectomy in the Jiaozuo People’s Hospital from January 1, 2013 to December 31, 2022 were retrospectively collected. The occurrence of DGE was recorded. Meanwhile, the multivariate binary logistic regression analysis was performed to screen the risk factors affecting the DGE. ResultsA total of 350 gastric cancer patients underwent laparoscopic distal gastrectomy and met the inclusion and exclusion criteria of this study were included, 17 (4.9%) of whom developed DGE. The multivariate binary logistic regression analysis results showed that the preoperative gastric outflow tract obstruction (OR=8.582, P=0.009), intraoperative jejunal nutrition tube indwelling (OR=14.317, P=0.010), more peritoneal drainage tube placement (OR=5.455, P=0.006), and intraoperative blood loss ≥140 mL (OR=4.912, P=0.018) increased the risk of DGE. ConclusionAccording to the results of this study, when patients undergoing laparoscopic distal radical gastrectomy for gastric cancer accompanied by preoperative gastric outflow tract obstruction, intraoperative jejunal nutrition tube indwelling, more peritoneal drainage tube placement, and more intraoperative blood loss, it should be paid more attention to prevention DGE, and early detection and treatment, so as to improve the prognosis of patients.
Forty-two patients with duodenal ulcer underwent highly selective vagotomy and mucosal antrectomy (HSV+MA) and were followed up for 3 years. Two weeks, 1 year and 3 year after operation, serum gastrim level and gastric emptying capacity were tested. The results show that he postoperative levels of serum gastrin were lower than the preoperative ones, but wih no significant difference (Ｐ＞0.05). Only a few patients had delayed gastric emptying 2 weeks and 1year after operation,but it returned to normal in 3 years .The authors conclude that HSV+MA is a better operative treatment for duodenal ulcer since it can abolish the factors of postoperative ulcer recurence and perserve the functions of the antrum and the pylorus.
ObjectiveTo analyze the risk factors for delayed gastric emptying (DGE) after pancreaticoduodenec-tomy (PD).
MethodsClinical data of 67 patients who underwent PD in our hospital from September 2012 to June 2014 were retrospectively analyzed.
ResultsTwenty-two patients were complicated with DGE of the 67 patients (32.8%) after PD operation. Univariate analysis showed that, diabetes mellitus, the anastomosis methods for stomach and jejunum, and diameter of circular stapler were risk factors for postoperative DGE, the patients who complicated with diabetes mellitus, treated with the traditional Child plus Braun anastomosis method, and treated with 25 mm circular stapler had higher incidence of DGE than patients who didn't complicate with diabetes mellitus, treated with Roux-en-Y anastomosis method, and treated with 28 mm circular stapler (P<0.05). Logistic regression identified 2 variables as independent risk factors which were associated with postoperative DGE, namely, anastomosis methods for stomach and jejunum (OR=0.062,95% CI:0.009-0.407,P=0.004) and diameter of circular stapler (OR=0.135,95% CI:0.034-0.538,P=0.005). The patients who treated with traditional Child plus Braun anastomosis method and 25 mm circular stapler had higher incidence of DGE.
ConclusionsThe incidence of DGE after PD is still high. The incidence of DGE could be reduced by using Roux-en-Y method to reconstruct digestive tract and 28 mm circular stapler during PD operation.
ObjectiveTo compare the effectiveness of antecolic duodenojejunostomy (ADJ) and retrocolic duodenojejunostomy (RDJ) after pylorus-preserving pancreaticoduodenectomy (PPPD).
MethodsRandomized controlled trials (RCTs) of ADJ versus RDJ after PPPD were searched in Cochrane Library, PubMed database, Embase database, Web of Science, Chinese biomedicine database, CNKI database, VIP database, and Wanfang database from inception to April 2014, as well as Google. After quality assessment of RCTs according to the Cochrane Handbook for Systematic Reviews of Interventions Version, Meta analysis was performed by RevMan 5.1 software.
ResultsFour RCTs of 462 patients in total were included in this Meta-analysis. The results of Meta-analysis showed that, there were no significant differences in the operation time (MD=14.02, 95% CI:-41.42-69.46, P=0.62), incidence of postoperative complications (RR=1.09, 95% CI:0.81-1.48, P=0.56), incidence of delayed gastric emptying (RR=0.63, 95% CI:0.31-1.28, P=0.20), incidence of pancreatic fistula (RR=1.13, 95% CI:0.72-1.75, P=0.60), incidence of abdominal abscess (RR=0.92, 95% CI:0.54-1.58, P=0.77), and mortality (RR=0.61, 95% CI:0.24-1.60, P=0.32) between ADJ group and RDJ group.
ConclusionsThe effectiveness of ADJ is similar with RDJ after PPPD, so the reconstruction way after PPPD can be routed according to the surgeon's preference.
ObjectiveTo analyze risk factors of gastric paralysis following pancreaticoduodenectomy so as to offer help for prevention and treatment of gastric paralysis.
MethodDomestic and international literatures about gastric paralysis following pancreaticoduodenectomy were collected, diagnostic criteria, risk factors, and the latest progress of gastric paralysis were summarized.
ResultsGastric paralysis is one of the most common postoperative complications following pancreaticoduodenectomy. It might be caused by many risk factors, such as operation method, gastrointestinal anastomosis, abdominal complications, chronic hyperglycemia, and excess infusion, etc.
ConclusionsAlthough definition of gastric paralysis by ISGPS is widely adopted, it fails to distinguish gastric paralysis from impaired gastric function related to other postoperative complications and it might result in an overestimation of its true morbidity. The risk factors of occurrence of gastric paralysis are still in controversy and results of research in different centers are not same, more prospective randomized controlled trials are needed.
ObjectiveTo assess the clinical efficacy of sonography guided Freka Trelumina placement by stylet displacement in patients with severely impaired gastric emptying.
MethodsTwenty-two patients with severely impaired gastric emptying monitored in the Intensive Care Unit from January 8 to May 18, 2016 were chosen to be our study subjects. Freka Trelumina was placed under ultrasonic guidance, and the guide wire displacement was used to determine the location of the catheter. We recorded whether the patient had an intra-gastric injection of warm water, the manual pushing times before the catheter passed through the pylorus, whether the operation succeeded, the time spent on guiding the placement, and the catheter depth. The pros and cons of the method in clinical use, and whether fasting state helped reduce the operating time were analyzed.
ResultsAmong the 22 patients, 20 had a successful Freka Trelumina placement, and the success rate was 91%. The number of manual pushing before the catheter passed through the pylorus was 1 in 4 cases (20%), 2 in 5 (25%), and equal to or more than 3 in 11 cases (55%). The catheter could be seen in the third part of duodenum only in 9 cases (45%). The mean placement procedure lasted (20.35±12.93) minutes for the successful cases. The time spent in the 11 patients with empty stomach was (15.00±9.87) minutes, less than (26.89±14.45) minutes in those 9 post prandial patients (P＜0.05).
ConclusionsWith stylet displacement to determine the location of the catheter, sonography guided Freka Trelumina placement has a high success rate. Ultrasonic guidance facilitates the insertion of the tubes in critically ill patients. For patients with empty stomach, it may help reduce the operating time.
