In recent years, with the standardization and promotion of laparoscopic techniques, the use of laparoscopic radical total gastrectomy is increasing. The main difficult points of this technique focus on digestive tract reconstruction after total gastrectomy. Esophagojejunal Roux-en-Y anastomosis is the first choice in laparoscopic reconstruction. There are two main methods for totally laparoscopic total gastrectomy (TLTG). One is esophagojejunal end-to-side anastomosis using circular stapler, and the other is esophagojejunal side-to-side anastomosis using linear staplers. TLTG has its advantages in digestive tract reconstruction including better visualization high safety and less trauma, which makes it a safe, convenient and effective method for reconstruction.

Methods of digestive tract reconstruction after distal gastrectomy include Billroth I, Billroth II and Roux-en-Y. Each of them has advantages and disadvantages respectively. Alkaline reflux gastritis (ARG) is one of the complications after distal gastrectomy, which is common after Billroth II. In the past 100 years, the ways of digestive tract reconstruction have been continuously improved and developed to prevent the occurrence of alkaline reflux gastritis, and Roux-en-Y is one of them. Still, there is a high incidence of Roux stasis syndrome resulting from Roux-en-Y, with impact on quality of life. Therefore, the appropriate reconstruction is needed urgently. Braun anastomosis was proposed in 1892 to lower the incidence of afferent syndrome. Because of its effect of diverting some alkaline digestive juice, it was applied to pancreaticoduodenectomy and distal gastrectomy. Some studies have proved its effect of diverting some alkaline digestive juice, but the diverted quantity was rarely shown. Besides, compared with Roux-en-Y, Billroth II with Braun anastomosis is safer and more convenient. Meantime it is likely to have benefits in aspect of preventing anemia and malnutrition. In order to provide evidence to clinical practice, this article summarizes the history and research advance of Billroth II with Braun anastomosis by reviewing previous reports.

Compared to that with laparoscopic assisted approach, intracorporeal anastomosis with totally laparoscopic radical total gastrectomy has the advantages of smaller incision, and better vision for operation, and may also be fit for patients with large size lesion, high-located lesions, or obesity. It remains controversial though several surgeons have reported the safety and feasibility of intracorporeal anastomosis with totally laparoscopic total gastrectomy. This review describes the recent technical advances in intracorporeal anastomoses with totally laparoscopic total gastrectomy, focusing on the reconstruction skills and indications. Current data on totally laparoscopic total gastric resection for gastric carcinoma revealed that all digestive tract reconstructions were performed with esophagus-jejunum Roux-en-Y anastomosis, and different reconstruction techniques of such Roux-en-Y anastomosis have certain advantages and disadvantages. Surgeons should make choice based on tumor location, esophageal diameter and personal skills in order to achieve maximal benefit to patients.

Several reconstruction techniques are available after gastrectomy. Roux-en-Y reconstruction following distal gastrectomy is the reference in terms of long-term functional and endoscopic outcomes. It is the preferred reconstruction for benign lesions and early gastric cancer. In patients with advanced gastric cancer, BillrothII (reconstruction is an acceptable alternative. After total gastrectomy, Roux-en-Y reconstruction is the simplest solution, with satisfactory functional outcome. Addition of a jejunal reservoir seems to improve long-term outcome after total gastrectomy and could be of benefit to patients with good prognosis. After distal or total gastrectomy, hand-sewn anastomoses should be preferred because of lower costs. Mechanical sutures can facilitate transhiatal esophagojejunostomy. After proximal gastrectomy, esophago-gastric anastomosis is the basic reconstruction method. Gastric remnant is made into gastric tube in the operation. The effect of pyloroplasty remains controversial, and further study is needed to improve the quality of life after operation.

There are various types of digestive tract reconstruction techniques after distal gastrectomy. Among them, Billroth I and II are still the predominant option in China at present. In recent years, Roux-en-Y configuration, jejunal interposition, J-pouch interposition (JPI), double-tract reconstruction, pylorus-preserving method, and laparoscopic reconstruction and anastomosis techniques have gained more attention in recent years. Although there is no universal and explicit guideline, the current consensus is that the reconstruction style should be adopted by the principles of digestive tract reconstruction, based on patient's condition, socioeconomic status and surgeon's experience.

OBJECTIVETo compare the clinical effect of 3S-type and P-loops digestive reconstruction after total gastrectomy for gastric cancer.

METHODSFrom February 2005 to February 2009, 85 cases underwent total gastrectomy in The First Affiliated Hospital of Henan University of Science and Technology. Two types of digestive reconstruction were performed with 3S-type jejunum(n=46) and P-loops Roux-en-Y esophagojejunostomy(n=39). The postoperative complications, nutrition index and the quality of life at half a year after surgery were comparatively analyzed.

RESULTSTwo types of digestive reconstruction had no statistical differences in operative time, postoperative complications and mortality(P>0.05). Compared with P-loops Roux-en-Y esophagojejunostomy at 6 months after operation, 3S-type jejunum had a lower incidence in dumping syndrome[4.3% (2/46) vs. 10.3% (4/39), P<0.05] and reflux esophagitis [10.8% (5/46) vs. 33.3% (13/39), P<0.05]. 3S-type jejunum was superior to P-loops Roux-en-Y esophagojejunostomy in serum total protein(55.7±3.1 g/L vs 50.3±5.1 g/L, P<0.05), albumin(36.5±3.6 g/L vs. 31.6±4.4 g/L, P<0.05), hemoglobin(120.2±13.4 g/L vs. 110.4±23.0 g/L, P<0.05), and nutritional assessment index(73.2±4.8 vs. 56.0±6.3, P<0.05).

CONCLUSIONReconstruction of stomach with 3S-type jejunum may be an effective way to prevent reflux esophagitis and dumping syndrome, and to improve the nutritional status and the quality of life.

OBJECTIVE: To explore the safety, feasibility and short-term efficacy of intracavitary uncut Roux-en-Y (URY) anastomosis in digestive tract reconstruction following laparoscopic total gastrectomy (LTG). METHODS: From November 2015 to January 2018, 67 gastric cancer patients underwent intracavitary URY following LTG to reconstruct the digestive tract at Oncological Surgery Department of Fujian Provincial Hospital. There were 41 males and 26 females with age of 50 to 81 (61.9±7.4) years and body mass index (BMI) of (23.4±3.2) kg/m². Among 67 patients, 19 were gastric cardia carcinomas, 33 were gastric body carcinomas, and 15 were gastric fundus carcinomas; tumor size was (3.4±2.3) cm; 22 were Borrmann type I, 15 were type II, 21 were type III, and 19 were type IV; 29 were highly or moderately differentiated adenocarcinoma, 23 were lowly differentiated adenocarcinoma, and 15 were signet-ring cell carcinoma. After conventional laparoscopic D2 radical gastrectomy, the duodenum was closed and dissociated at 2 cm below the pyloric ring using the Echelon-flex endoscopic articulated linear Endo-GIA stapler, and the esophagus was dissociated above the esophagogastric junction (EGJ).URY and digestive tract reconstruction were performed under the direct vision of laparoscope: (1) Side-to-side esophagojejunostomy: An incision of 0.5 cm was made in the left lower edge of the esophageal closed end; jejunum about 25 cm distal away from the Treitz ligament was elevated to the lower end of esophagus; another incision of 0.5 cm was made in the contralateral of mesenteric side; both arms of the linear Endo-GIA stapler were inserted into the windows opened through esophagus and jejunum respectively to complete side-to-side anastomosis. The common opening of esophagus and jejunum was closed to complete esophagojejunostomy, forming the chyme outflow tract. (2) Side-to-side Braun jejunojejunostomy: Incisions of 0.5 cm were made in the proximal jejunum about 10 cm away from the esophagojejunal anastomosis and 35-40 cm away from the contralateral of mesenteric side of distal jejunum respectively for proximal-distal side-to-side jejunojejunostomy. The common opening was closed to form the biliopancreatic duodenal juice outflow tract. (3) Closure of the input loop jejunum in the esophagojejunal anastomosis: The input loop jejunum 2-3 cm away from the esophagojejunal anastomosis was closed using the non-blade linear stapler (ATS45NK), and the biliopancreatic duodenal juice reflux was blocked. Clinical data of these patients were collected for retrospective case series study. Surgical and digestive tract functional recovery, perioperative complications, as well as postoperative nutritional status were observed. Moreover, related indexes, such as anastomosis function and tumor recurrence were evaluated through endoscopic and imaging examinations during postoperative follows-up. RESULTS: All the 67 patients completed the surgery successfully. The mean operative time was (259.4±38.5) minutes, digestive tract reconstruction time was (38.2±13.2) minutes, intraoperative blood loss was (73.4±38.4) ml, and number of harvested lymph node was 36.2±14.2. The mean distance from upper resection margin to upper tumor edge was (3.3±1.2) cm, distance from upper resection margin to dentate line was (1.2±0.7) cm, and 1 case had positive upper incisal margin, which became negative after the second resection. Moreover, the average length of the auxiliary incision was (3.2±0.4) cm. The mean postoperative intestinal exhaust time was (52.8±26.4) hours, time to liquid diet was (64.8±28.8) hours, and postoperative hospital stay was (8.4±2.5) days. The morbidity of postoperative complication was 10.4%(7/67). Among these 7 cases, 4 cases were grade IIIa of Clavien-Dindo classification, including 2 with esophagojejunal anastomosis leakage, 1 with duodenal stump leakage, and 1 with abdominal infection, and all these patients were recovered after conservative treatment. All the 67 patients were followed up. The mean nutrition index 12 months after surgery was 53.4±4.2, diameter of esophagojejunal anastomosis was (3.9±0.6) cm, the incidence of Roux-en-Y stasis syndrome was 3.0% (2/67), and the incidence of reflux esophagitis was 4.5% (3/67). No patient had recanalization of the closed input loop of esophagojejunal anastomosis, anastomotic stenosis, obstruction, or tumor recurrence at anastomosis. CONCLUSION Intracavitary URY anastomosis following LTG for digestive tract reconstruction is safe and feasible, leading to fast postoperative recovery of digestive tract function and favorable short-term efficacy.

BACKGROUND: The results of studies comparing Billroth-I (B-I) with Roux-en-Y (R-Y) reconstruction on the quality of life (QoL) are still inconsistent. The aim of this trial was to compare the long-term QoL of B-I with R-Y anastomosis after curative distal gastrectomy for gastric cancer. METHODS: A total of 140 patients undergoing curative distal gastrectomy with D2 lymphadenectomy in West China Hospital, Sichuan University from May 2011 to May 2014 were randomly assigned to the B-I group ( N  = 70) and R-Y group ( N  = 70). The follow-up time points were 1, 3, 6, 9, 12, 24, 36, 48, and 60 months after the operation. The final follow-up time was May 2019. The clinicopathological features, operative safety, postoperative recovery, long-term survival as well as QoL were compared, among which QoL score was the primary outcome. An intention-to-treat analysis was applied. RESULTS: The baseline characteristics were comparable between the two groups. There were no statistically significant differences in terms of postoperative morbidity and mortality rates, and postoperative recovery between the two groups. Less estimated blood loss and shorter surgical duration were found in the B-I group. There were no statistically significant differences in 5-year overall survival (79% [55/70] of the B-I group vs. 80% [56/70] of the R-Y group, P  = 0.966) and recurrence-free survival rates (79% [55/70] of the B-I group vs. 78% [55/70] of the R-Y group, P  = 0.979) between the two groups. The scores of the global health status of the R-Y group were higher than those of the B-I group with statistically significant differences (postoperative 1 year: 85.4 ± 13.1 vs . 88.8 ± 16.1, P  = 0.033; postoperative 3 year: 87.3 ± 15.2 vs . 92.8 ± 11.3, P  = 0.028; postoperative 5 year: 90.9 ± 13.7 vs . 96.4 ± 5.6, P  = 0.010), and the reflux (postoperative 3 year: 8.8 ± 12.9 vs . 2.8 ± 5.3, P  = 0.001; postoperative 5 year: 5.1 ± 9.8 vs . 1.8 ± 4.7, P  = 0.033) and epigastric pain (postoperative 1 year: 11.8 ± 12.7 vs. 6.1 ± 8.8, P  = 0.008; postoperative 3 year: 9.4 ± 10.6 vs. 4.6 ± 7.9, P  = 0.006; postoperative 5 year: 6.0 ± 8.9 vs . 2.7 ± 4.6, P  = 0.022) were milder in the R-Y group than those of the B-I group at the postoperative 1, 3, and 5-year time points. CONCLUSIONS: Compared with B-I group, R-Y reconstruction was associated with better long-term QoL by reducing reflux and epigastric pain, without changing survival outcomes.

Selection of the ideal technique for alimentary tract reconstruction after gastrointestinal surgery has been a major concern for surgeons. Although various reconstruction methods are available after gastrectomy, there are obvious differences between proximal gastrectomy and other procedures because of its characteristics in anatomy and physiology. It is an important way to make an individualized and feasible scheme for reconstruction in order to improve patient's quality of life.
