Graft dilatation and Barrett’s esophagus in adults after gastric pullup and jejunal interposition for long-gap esophageal atresia

BACKGROUND Esophageal replacement(ER)with gastric pull-up(GPU)or jejunal interposition(JI)used to be the standard treatment for long-gap esophageal atresia(LGEA).Changes of the ER grafts on a macro-and microscopic level however,are unknown.AIM To evaluate long-term clinical symptoms and anatomical and mucosal changes in adolescents and adults after ER for LGEA.METHODS A cohort study was conducted including all LGEA patients≥16 years who had undergone GPU or JI between 1985-2003 at two tertiary referral centers in the Netherlands.Patients underwent clinical assessment,contrast study and endoscopy with biopsy.Data was collected prospectively.Group differences between JI and GPU patients,and associations between different outcome measures were assessed using the Fisher’s exact test for bivariate variables and the Mann-Whitney U-test for continuous variables.Differences with a P-value<0.05 were considered statistically significant.RESULTS Nine GPU patients and eleven JI patients were included.Median age at follow-up was 21.5 years and 24.4 years,respectively.Reflux was reported in six GPU patients(67%)vs four JI patients(36%)(P=0.37).Dysphagia symptoms were reported in 64%of JI patients,compared to 22%of GPU patients(P=0.09).Contrast studies showed dilatation of the jejunal graft in six patients(55%)and graft lengthening in four of these six patients.Endoscopy revealed columnar-lined esophagus in three GPU patients(33%)and intestinal metaplasia was histologically confirmed in two patients(22%).No association was found between reflux symptoms and macroscopic anomalies or intestinal metaplasia.Three GPU patients(33%)experienced severe feeding problems vs none in the JI group.The median body mass index of JI patients was 20.9 kg/m^(2) vs 19.5 kg/m^(2) in GPU patients(P=0.08).CONCLUSION The majority of GPU patients had reflux and intestinal metaplasia in 22%.The majority of JI patients had dysphagia and a dilated graft.Follow-up after ER for LGEA is essential.

Proximal gastrectomy with jejunal interposition and TGRY anastomosis for proximal gastric cancer

AIM: To compare the short-term outcomes of patients who underwent proximal gastrectomy with jejunal interposition (PGJI) with those undergoing total gastrectomy with Roux-en-Y anastomosis (TGRY).

Beneficial effects of continual jejunal interposition after subtotal gastrectomy

Background The ideal post-gastrectomy reconstruction procedure should maintain the normal digestive function and restore intestinal transit to improve the patient quality of life. The aim of this study was to evaluate the effects of integral continual jejunal interposition after subtotal gastrectomy on the nutritional status, glucose levels, and gastric-intestinal motility. Methods The study investigated the effects of the integral continual jejunal interposition, the Billroth I and Billroth II operations, and the isolated jejunal interposition following subtotal distal gastrectomy on the blood glucose, insulin, routine blood parameters, liver function, and myoelectrical activity in Beagle dogs. Results The weights of the dogs decreased during the first post-operative weeks. Dogs in the integral continual jejunal interposition, Billroth I, and Billroth II groups gained significantly more weight by 8 weeks. The prognosis nutrition index of the dogs decreased in the first 2 post-operative weeks and increased significantly by 4 weeks in the integral continual jejunal interposition and Billroth I groups. The group with duodenal exclusion （Billroth II） had significantly higher glucose levels compared to the normal control group. The insulin curve was much higher in dogs that underwent the Billroth I, continual jejunal interposition, and isolated jejunal interposition than the Billroth II and normal groups. The frequencies of fasting and postprandial jejunal pacesetter potentials （PPs） were greater in the continual jejunal interposition and Billroth I groups than that in the isolated jejunal interposition and Billroth II groups. The percentage of aboral propagation of PPs was greater in the continual jejunal interposition group than the Billroth I, isolated jejunal interposition, and Billroth II groups. Conclusion Continual jejunal interposition after subtotal gastrectomy avoids jejunal transection, maintains the duodenal Dassaqe and food storaae baas, and reduces the influence of blood qlucose and insulin.

Cholangio-duodenal interposition of an isolated jejunal segment after central resection

BACKGROUND: Bilio-intestinal drainage is routinely per- formed by Roux-en-Y reconstruction after resection of the central bile duct. Alternatively reconstruction can be achieved by cholangio-duodenal interposition of an isolated jejunal segment (CDJI). This method offers the benefit of potential endoscopic control and intervention during fol- low-up. Critics of CDJI assume a higher rate of postopera- tive cholangitis compared to the Roux-en-Y construction. METHODS: Seventy-six patients with malignant tumors (n = 56) or benign strictures and choledochal cysts (n =20) were treated between 1989 and 2002 by cholangio-duodenal interposition of an isolated jejunal segment (measuring 15- 25 cm) after central bile duct resection. In 22 patients endoscopic control was first performed postoperatively dur- ing hospitalization. In 12 patients bilio-intestinal anastomo- sis could be inspected endoscopically. In the remaining patients the anastomosis could not be visualized endoscopi- cally because of kinking of the jejunal segment, but in all patients it could be evaluated by endoscopic retrograde cholangiography (ERC). RESULTS: During follow-up, 25 (33%) patients died from extrahepatic tumor recurrence. Three patients receiving CDJI after severe iatrogenic bile duct injury developed anas- tomotic strictures. Two of these patients were treated by endoscopic pigtail drainage, and one was treated by percu- taneous drainage. Two patients who had received CDJI af- ter choledochal cyst resection developed cholestasis post- operatively because of sludge formation (1 patient) and an intrahepatic concrement (1), which could be solved endo- scopically. One patient after resection of a Klatskin tumor developed an anastomotic stricture which could not be vi- sualized endoscopically, making percutaneous drainage necessary. The rate of postoperative cholangitis after CDJI in our patients was comparable to that after the Roux-en-Y reconstruction.CONCLUSION: Interposition of an isolated jejunal seg- ment for reconstruction after bile duct resection should be performed in patients with a high risk of postoperative ste- nosis. To benefit endoscopic follow-up the jejunal segment should be shorter than 20 cm.

Comparative analysis of two digestive tract reconstruction methods in total laparoscopic radical total gastrectomy

BACKGROUND The incidence of gastric cancer has significantly increased in recent years.Surgical resection is the main treatment,but the method of digestive tract reconstruction after gastric cancer surgery remains controversial.In the current study,we sought to explore a reasonable method of digestive tract reconstruction and improve the quality of life and nutritional status of patients after surgery.To this end,we statistically analyzed the clinical results of patients with gastric cancer who underwent jejunal interposition double-tract reconstruction(DTR)and esophageal jejunum Roux-en-Y reconstruction(RY).AIM To explore the application effect of DTR in total laparoscopic radical total gastrectomy(TLTG)and evaluate its safety and efficacy.METHODS We collected the relevant data of 77 patients who underwent TLTG at the Fourth Hospital of Hebei Medical University from October 2021 to January 2023.Among them,35 cases were treated with DTR,and the remaining 42 cases were treated with traditional RY.After 1:1 propensity score matching,the cases were grouped into 31 cases per group,with evenly distributed data.The clinical characteristics and short-and long-term clinical outcomes of the two groups were statistically analyzed.RESULTS The two groups showed no significant differences in basic data,intraoperative blood loss,number of lymph node dissections,first defecation time after operation,postoperative hospital stay,postoperative complications,and laboratory examination results on the 1st,3rd,and 5th days after operation.The operation time of the DTR group was longer than that of the RY group[(307.58±65.14)min vs(272.45±62.09)min,P=0.016],but the first intake of liquid food in the DTR group was shorter than that in the RY group[(4.45±1.18)d vs(6.0±5.18)d,P=0.028].The incidence of reflux heartburn(Visick grade)and postoperative gallbladder disease in the DTR group was lower than that in the RY group(P=0.033 and P=0.038).Although there was no significant difference in body weight,hemoglobin,prealbumin,and albumin between the two groups at 1,3 and 6 months after surgery,the diet of patients in the DTR group was better than that in the RY group(P=0.031).CONCLUSION The clinical effect of DTR in TLTG is better than that of RY,indicating that it is a more valuable digestive tract reconstruction method in laparoscopic gastric cancer surgery.

Vagus-preserving Merendino-Procedure for Early Carcinoma ofthe Gastroesophageal Junction

Optimal therapy for early carcinoma of the gastroesophageal junction remains uncertain. Treat- ment alternatives discussed today reach from endoluminal techniques to radical esophagectomy with 2- or 3-?eld lymphadenectomy. In this context, the Merendino procedure with preservation of the vagal innerva- tion to the stomach appears as an interesting therapeutic alternative. This paper summarizes indications, operative technique, and functional results with respect to postoperative quality of life, based upon 2 cases operated in our department.
