Short- and long-term outcomes of Roux-en-Y and Billroth II with Braun reconstruction in total laparoscopic distal gastrectomy: a retrospective analysis.

BACKGROUND: The controversy surrounding Roux-en-Y (R-Y) and Billroth II with Braun (BII + B) reconstruction as an anti-bile reflux procedure after distal gastrectomy has persisted. Recent studies have demonstrated their efficacy, but the long-term outcomes and postoperative quality of life (QoL) among patients have yet to be evaluated. Therefore, we compared the short-term and long-term outcomes of the two procedures as well as QoL. METHODS: The clinical data of 151 patients who underwent total laparoscopic distal gastrectomy (TLDG) at the Gastrointestinal Surgery Department of the Second Hospital of Fujian Medical University from January 2016 to December 2019 were retrospectively analyzed. Of these, 57 cases with Roux-en-Y procedure (R-Y group) and 94 cases with Billroth II with Braun procedure were included (BII + B group). Operative and postoperative conditions, early and late complications, endoscopic outcomes at year 1 and year 3 after surgery, nutritional indicators, and quality of life scores at year 3 postoperatively were compared between the two groups. RESULTS: The R-Y group recorded a significantly longer operative time (194.65 ± 21.52 vs. 183.88 ± 18.02 min) and anastomotic time (36.96 ± 2.43 vs. 27.97 ± 3.74 min) compared to the BII + B group (p < 0.05). However, no other significant differences were observed in terms of perioperative variables, including blood loss (p > 0.05). Both groups showed comparable rates of early and late complications. Endoscopic findings indicated similar food residuals at years 1 and 3 post-surgery for both groups. The R-Y group had a lower occurrence of residual gastritis and bile reflux at year 1 and year 3 after surgery, with a statistically significant difference (p < 0.001). Reflux esophagitis was not significantly different between the R-Y and BII + B groups in year 1 after surgery (p = 0.820), but the R-Y group had a lower incidence than the BII + B group in year 3 after surgery (p = 0.023). Nutritional outcomes at 3 years after surgery did not differ significantly between the two groups (p > 0.05). Quality of life scores measured by the QLQ-C30 scale were not significantly different between the two groups. However, on the QLQ-STO22 scale, the reflux score was significantly lower in the R-Y group than in the BII + B group (0 [0, 0] vs. 5.56 [0, 11.11]) (p = 0.003). The rest of the scores were not significantly different (p > 0.05). CONCLUSION: Both R-Y and B II + B reconstructions are equally safe and efficient for TLDG. Nevertheless, the R-Y reconstruction reduces the incidence of residual gastritis, bile reflux, and reflux esophagitis, as well as postoperative reflux symptoms, and provides a better quality of life for patients. R-Y reconstruction is superior to BII + B reconstruction for TLDG.

Comparison of short-term and long-term clinical effects of modified overlap anastomosis and conventional incision-assisted anastomosis in laparoscopic total gastrectomy.

BACKGROUND: To compare short-term and long-term clinical effects of modified overlap anastomosis and conventional incision-assisted anastomosis for laparoscopic total gastrectomy. METHODS: This retrospective cohort study included patients with gastric cancer admitted to the Second Affiliated Hospital of Fujian Medical University from January 2016 to March 2020. Quality of life, intraoperative and postoperative conditions were analyzed. RESULTS: Compared with the conventional assisted group, the modified overlap group showed a shorter auxiliary incision, milder postoperative pain, shorter time to the first postoperative anal exhaust, shorter time to the first postoperative liquid food intake, and shorter postoperative stay. There were no differences between the two groups regarding operation time, esophagus-jejunum anastomosis time, intraoperative blood loss, number of lymph nodes dissected, and length of the upper incision margin. There were no differences between the two groups regarding postoperative early and late complications. There were no differences between the two groups regarding the QLQ-C30 scale three years after the operation. The scores of the QLQ-STO22 scale 3 years after the operation showed significantly lower scores for dysphagia and feeding limit in the modified overlap group than those in the conventional assisted anastomosis group. There was no recurrence in the modified overlap group but one patient in the conventional assisted group. CONCLUSIONS: Patients undergoing totally laparoscopic total gastrectomy with modified overlap anastomosis have better minimal invasiveness and faster post-operative recovery than conventional incision-assisted anastomosis.

Comparison of clinical efficacy between modified Kamikawa anastomosis in laparoscopic proximal gastrectomy and Roux-en-Y anastomosis in laparoscopic total gastrectomy.

To investigate the short-term clinical efficacy of laparoscopic proximal gastrectomy with modified Kamikawa anastomosis and laparoscopic total gastrectomy with Roux-en-Y anastomosis. Retrospective cohort study was conducted. The clinicopathological data of 268 patients who underwent laparoscopic proximal gastrectomy for adenocarcinoma of esophagogastric junction and upper gastric adenocarcinoma from January 2016 to October 2022 were collected. Among 268 patients, 26 underwent laparoscopic proximal gastrectomy with modified Kamikawa anastomosis were assigned to Kamikawa group and 242 underwent laparoscopic total gastrectomy with Roux-en-Y anastomosis were assigned to Roux-en-Y group. The sex, age, BMI, preoperative albumin, maximum tumor diameter, histological grade, and pathological stage of patients in the Kamikawa group and the Roux-en-Y group were subjected to 1:1 propensity score matching. After matching, 16 patients in Kamikawa group and Roux-en-Y group were respectively included in this study. Outcome measures: (1) Intraoperative condition. (2) Postoperative recovery. (3) Follow-up information. The patients' nutritional status, reflux esophagitis and anastomotic stoma were investigated by outpatient and telephone follow-up. Nutritional status assessment comprising body mass index and Nutritional Risk Screening 2002 score. (1) Intraoperative condition. All patients successfully underwent laparoscopic proximal gastrectomy and total gastrectomy. Compared with Roux-en-Y group, the digestive tract reconstruction time in Kamikawa group was longer 93.0(74.0-111.0)min vs. 39.7(35.1-46.2)min, t = -2.001, P = 0.055., and the difference was statistically significant (P < 0.05). There was no statistically significant difference in total operation time and intraoperative blood loss (P > 0.05). (2) Postoperative recovery. There was no statistically significant difference between Kamikawa group and Roux-en-Y group in first anal exhaust time, first postoperative liquid intake time, postoperative hospitalization time, and postoperative complications (P > 0.05). (3) Follow-up information. All patients were followed up. BMI and NRS 2002 scores in Kamikawa group were better than those in Roux-en-Y group at 6 and 12 months after surgery 22.9 ± 3.0 kg/m2 vs. 20.8 ± 2.2 kg/m2, t = 2.165, P = 0.038; 23.1 ± 3.0 kg/m2 vs. 20.3 ± 2.2 kg/m2, t = 3.022, P = 0.005 and 2 (1-2) vs. 2 (1-3), Z = -2.585, P = 0.010; 2 (1-2) vs. 2 (1-3), Z = -2.273, P = 0.023., the difference was statistically significant (P < 0.05). There was no significant difference in GERD scale score and occurrence of ≥ Grade B reflux esophagitis at 6 and 12 months after surgery between Kamikawa group and Roux-en-Y group (P > 0.05). Anastomotic stenosis was not found in all patients by postoperative upper gastrointestinal angiography. Laparoscopic proximal gastrectomy with modified Kamikawa anastomosis is safe and feasible for the treatment of esophagogastric junction and upper gastric adenocarcinoma, and can achieve good anti-reflux effect. Besides, compared with traditional laparoscopic total gastrectomy, its postoperative nutritional status is better.

Comparison of proximal gastrectomy with double-flap technique and double-tract reconstruction for proximal early gastric cancer: a meta-analysis.

Surgical resection is the main treatment for proximal gastric cancer, but there is no consensus on its reconstruction. We carried out a meta-analysis to evaluate the effects of double-tract reconstruction (DTR) and double-flap technique (DFT) on postoperative quality of life in patients with proximal gastric cancer. Systematic searches of PubMed, Web of Science, EBSCO, and the Cochrane Library were performed. Literature for the last 5 years was searched without language restrictions. The cutoff date for the search was 12 April 2023. Literature and research searches were conducted independently by two researchers and data were extracted. Statistical analyses were performed using Review Manager (Revman) 5.4 software. Fixed models were used when heterogeneity was small and random-effects models were used for meta-analysis when heterogeneity was large. The study was registered with PROSPERO, CRD 42023418520. Surgical time was significantly shorter in the DTR group than in the DFT group (P = 0.03). There were no significant differences between DFT and DTR in terms of age, gender, pathological stage, preoperative body mass index, surgical bleeding, and perioperative complications. There was no statistically significant difference between the two groups in terms of reflux esophagitis and PPI intake, but DFT was superior to DTR in weight improvement at 1 year after surgery (P < 0.0001). Compared with DTR, DFT reconstruction is more demanding and time-consuming, but its postoperative nutritional status is better, so it should be the first choice for GI reconstruction in most patients with early proximal gastric cancer. However, DTR should be the best choice for patients who have difficulty operating.
