ObjectiveTo explore the effect of exogenous ghrelin on early recovery of rats after subtotal gastrectomy. MethodsTwelve rats undergoing subtotal gastrectomy (B-Ⅰtype) were randomly divided into two groups, and saline or ghrelin was intraperitoneally injected in two groups, respectively. The body weight and daily food intake were measured before operation and on 1-7 d after operation. Rats were killed on day 7 after operation and the expressions of ghrelin mRNA in the fundus of stomach and anastomotic stoma was determined by realtime fluorescent quantitative PCR assay. The anastomotic bursting pressure and hydroxyproline content of anastomotic stoma tissues were also detected. ResultsThere was no significant difference (P＞0.05) in pre and postoperative body weight between two groups. Gradual decrease in postoperative body weight among the rats of saline group was observed which was significantly lower than that before operation (Plt;0.01). Body weight reached it’s lowest on day 1 after operation (Plt;0.01), after which it gradually increased but was still lower than that before operation (Plt;0.01). The postoperative body weight of rats in ghrelin group gradually decreased too, and was also significantly lower than preoperative body weight (Plt;0.01), except for the day 1 after operation (P=0.693). It reached the lowest on day 4 after operation (Plt;0.01), then it gradually increased but was still lower than that before operation (Plt;0.05 or Plt;0.01). The cumulative food intake of rats in ghrelin group was （52.50±6.77） g, which was significantly higher than that in saline group 〔(45.67±7.47) g〕, Plt;0.05. On day 7 after operation, relative expression of ghrelin mRNA in the fundus of stomach of rats in ghrelin group was 0.08±0.04, which was significantly lower than that in saline group (0.22±0.07), Plt;0.01. Compared with saline group, ghrelin-treated rats displayed significantly higher bursting pressure 〔（155.83±6.62） mm Hg vs. （172.33±10.44） mm Hg, Plt;0.05〕 higher hydroxyproline content 〔 (0.43±0.05) μg/mg wet tissue vs. （0.50±0.29） μg/mg wet tissue, Plt;0.01〕 at the anastomotic stoma. ConclusionGhrelin may effectively promote the early recovery of rats after subtotal gastrectomy.
ObjectiveTo compare clinical outcome between single-incision laparoscopic subtotal gastrectomy (SILSG) versus laparoscopy-assisted subtotal gastrectomy (LASG) in treatment of benign gastric ulcer and duodenal ulcer. MethodsClinical data of 37 patients with benign gastric ulcer or duodenal ulcer who underwent laparoscopic subtotal gastrectomy between Jan. 2008 and Feb. 2015 at Shengjing Hospital of China Medical University was collected retrospectively. Among them, 15 patients underwent SILSG and 22 patients underwent LASG. Demographic, intraoperative, and postoperative data was analyzed and compared between the 2 groups. ResultsThe operative time of SILSG group was significantly longer than that of LASG group (P < 0.050). However, the postoperative hospital stay was significantly shorter (P < 0.050), and the total patient scar assesment scale (PSAS) score was significantly lower (P < 0.050) in the SILSG group than those of LASG group. There was no significant difference between the 2 groups with respect to other variables (P > 0.050), such as conversion rate, intraoperative blood loss, postoperative exhaust time, incidence of complication, and visual analog scale score of pain. All patients received postoperative follow up, and the period ranged from 6 months to 25 months, with a median of 11 months. During the follow up period, no one suffered from incision hernia and recurrence of ulcer. ConclusionCompared with LASG, SILSG is a technically feasible procedure with better cosmesis and equivalent curability.
The conectration of cholecystokinin infasting serum was determined by radioimmunoessay in 30 patients with gastric antrum cancer before and after radical sbutotal gastrectomy.It was 119.6±142.2pmol/L before the operation and 78.5±149.2pmol/L after the operation,which was significantly lower than that before the operation,P=0.022. The result suggests that the reduction of cholecytokinin secretion after gastrectomy was one of the important causes in the bile stasis,the disturbance of gallbladder emptying funcion and the formation of gallstone.
Objective To systematically review perioperative safety and middle-term and long-term complications of Roux-en-Y anastomosis and Billroth-Ⅰ anastomosis after distal subtotal gastrectomy by a meta-analysis. Methods Literatures about Roux-en-Y and Billroth-Ⅰ anastomoses after distal subtotal gastrectomy in Embase, PubMed, MedLine, and the Cochrane Library databases were searched. Retrieval time was from December 1, 2015 to March 1, 2016. According to the inclusion and exclusion criteria, two reviewers independently screened literatures, extracted data, and evaluated the qualities of the included studies. Then meta-analysis was performed using Review Manager Version 5.1 software. Results Five randomized controlled trials (RCTs) were finally included involving 600 patients, of which 302 patients were underwent Roux-en-Y anasomosis, 298 patients were underwent Billroth-Ⅰ anasomosis. The results of meta-analysis showed that the Billroth-Ⅰ anastomosis operation had more advantages in the operative time 〔WMD: 38.95; 95%CI: (19.86, 58.04);P<0.000 1〕 and the intraoperative bleeding 〔WMD: 34.85; 95%CI: (2.13, 67.56);P=0.04〕. However, the Roux-en-Y anastomosis had more significant effects in the prevention of bile reflux 〔OR: 0.03; 95%CI: (0.01, 0.11);P<0.000 01〕 and the residual gastritis 〔OR: 0.37; 95%CI: (0.25, 0.54);P<0.000 01〕. There were no differences in the hospital stay 〔WMD: 2.96; 95%CI: (–0.00, 5.93);P=0.05〕, anastomotic leakage 〔OR: 0.43; 95%CI: (0.11, 1.68);P=0.23〕, anastomotic stricture 〔OR: 1.84; 95%CI: (0.61, 5.53);P=0.27〕, reflux esophagitis〔OR: 0.63; 95%CI: (0.28, 1.44);P=0.27〕, and delayed gastric emptying 〔OR: 1.24; 95%CI: (0.46, 3.30);P=0.67〕 between the Roux-en-Y anastomosis and Billroth-Ⅰ anastomosis. Conclusions Billroth- I anastomosis and Roux-en-Y anastomosis have their own advantages and disadvantages, in term of safety of Billroth- I anastomosis is better, but it’s quality of life is worse as compared with Roux-en-Y anastomosis. However, more high-quality, well-designed, adequate RCTs data are needed to validate.
Objective To explore the pain after discharged in patients with radical total gastrectomy under painless ward management, and to analyze the causes of pain in order to guide the treatment strategy after discharge. Methods Retrospective analysis was performed on the pain data of 82 patients who underwent radical total gastrectomy in The First Affiliated Hospital of Air Force Military Medical University from December 2015 to April 2017, and the situation of pain was followed-up at 2 weeks, 1 month, 2 months, and 3 months after discharged. Results Mild pain occurred in 25 patients at the 2 weeks after discharged; mild pain occurred in 38 patients and moderate pain occurred in7 patients at the first month after discharged; mild pain occurred in 31 patients and moderate pain occurred in 4 patients at the second month after discharged; 19 patients had mild pain at the third month after discharged. There was no significant difference in pain scores between male patients and female patients, <60 years old patients and ≥60 years old patients, patients’ operative time<180 min and patients’ operative time ≥180 min, patients’ intraoperative blood loss<200 mL and patients’ intraoperative blood loss ≥200 mL at the all time points, including the second week, the first, the second, and the third month after discharge ( P>0.05). Conclusion Painless ward management can effectively control the degree of pain in discharged patients who underwent radical total gastrectomy.
ObjectiveTo systematically evaluate the efficacy and safety of proximal gastrectomy (PG) versus total gastrectomy (TG) for the treatment of Siewert type Ⅱ/Ⅲ adenocarcinoma of the esophagogastric junction (AEG). MethodsPubMed, The Cochrane Library, Web of Science, EMbase, CNKI, Wanfang, and VIP databases were searched for literature comparing the efficacy and safety of PG and TG for the treatment of Siewert type Ⅱ/Ⅲ AEG. The search period was from database inception to March 2023. Meta-analysis was performed using Review Manager 5.4 software. ResultsA total of 23 articles were included, including 16 retrospective cohort studies, 5 prospective cohort studies, and 2 randomized controlled trials. The total sample size was 2 826 patients, with 1 389 patients undergoing PG and 1 437 patients undergoing TG. Meta-analysis results showed that compared with TG, PG had less intraoperative blood loss [MD=−19.85, 95%CI (−37.20, −2.51), P=0.02] and shorter postoperative hospital stay [MD=−1.23, 95%CI (−2.38, −0.08), P=0.04]. TG had a greater number of lymph nodes dissected [MD=−6.20, 95%CI (−7.68, −4.71), P<0.001] and a lower incidence of reflux esophagitis [MD=3.02, 95%CI (1.24, 7.34), P=0.01]. There were no statistically significant differences between the two surgical approaches in terms of operative time, postoperative survival rate (1-year, 3-year, 5-year), and postoperative overall complications (P>0.05). ConclusionPG has advantages in terms of intraoperative blood loss and postoperative hospital stay, while TG has advantages in terms of the number of lymph nodes dissected and the incidence of reflux esophagitis. There is no significant difference in long-term survival between the two surgical approaches.
Objective To compare short-term effects of totally laparoscopic total gastrectomy (TLTG) and laparoscopic assisted total gastrectomy (TATG) in treatment of resectable gastric cancer. Methods The EMbase, PubMed, The Cochrane Library, Web of Science, CBM, CNKI, and WanFang Data databases were searched by computer. According to the inclusion and exclusion criteria of the literatures, the comparative research literatures were selected. The relevant data were extracted and the literature evaluation was applied. The Revman 5.3 software was applied for the meta-analysis. Results A total of 11 articles (6 Chinese literatures, 5 English literatures) were included, including 1 491 patients clinically diagnosed with the gastric cancer. The results of meta-analysis showed: compared with the LATG group, the TLTG group had the less intraoperative blood loss ［MD=–17.59, 95% CI (–30.81, –4.37), P=0.009］, shorter incision length ［MD=–4.50, 95% CI (–4.92, –4.09), P<0.000 01］, and earlier first anal exhaust time ［MD=–0.16, 95% CI (–0.28, –0.04), P=0.007］in the treatment of gastric cancer; Besides, the first time of postoperative fluid intake of the TLTG group was earlier ［MD=–0.47, 95% CI (–0.86, –0.08), P=0.02］ and the postoperative hospital stay of the TLTG group was shorter ［MD=–0.59, 95% CI (–0.94, –0.24), P=0.000 9］; In the TLTG group, the VAS score was lower on the first postoperative day ［MD=–3.10, 95% CI (–3.48, –2.72), P<0.000 01］ and on the third postoperative day ［MD=–2.30, 95% CI (–2.57, –2.03), P<0.000 01］. There were no significant differences in the operation time, proximal margin distance, distal margin distance, lymph node dissection, and postoperative adverse reactions between the two groups (P>0.05). The subgroup analysis of the postoperative adverse reactions showed that there were no significant differences in the anastomotic stricture, anastomotic leakage, and anastomotic bleeding (P>0.05). Conclusions TLTG has some advantages of less bleeding, shorter incision, earlier ventilation and feeding, shorter postoperative hospital stay, and light postoperative pain in treatment of resectable gastric cancer. However, due to quantitative and qualitative limitations of included studies, above conclusions still need to be carried out more and high quality researches are validated.
ObjectiveTo explore feasibility and safety of π-shaped esophagojejunal anastomosis in totally laparoscopic total gastrectomy (TLTG).MethodThe clinical data of 20 patients who underwent TLTG, admitted in the Affiliated Hospital of Xuzhou Medical University from January 2018 to December 2018 were retrospectively analyzed.ResultsTLTG with π-shaped esophagojejunal anastomosis was successfully carried out in all 20 patients. The operative time was (236.0±55.5) min, the π-shaped esophagojejunal anastomosis time was (25.7±4.8) min, the intraoperative blood loss was (192.0±148.9) mL, the operative incision length was (3.7±0.8) cm. The postoperative pain score was 2.4±1.1, the first flatus time was (3.1±0.9) d, the first postoperative ambulation time was (1.8±0.7) d, the removal time of nasoenteral nutrution tube was (7.4±2.4) d, the liquid diet time was (6.2±1.4) d, the removal time of intraoabdominal drainage tube was (7.8±2.8) d, the postoperative hospital stay was (10.8±3.0) d. There was no death related to the anastomosis in all patients. Two patients developed a little pleural effusion and 1 patient developed lymphatic leakage were cured with conservative treatment. One patient with intraabdominal encapsulated effusion was cured by puncture and drainage treating. There was no postive incisal margin. The length of upper segment of resection form gastric cancer was (2.3±1.7) cm, the maximum tumor diameter was (4.9±2.8) cm, the number of dissected lymph nodes was 27.9±5.6. All patients were followed up 3–15 months. Eight patients underwent endoscopic examination had no obvious anastomosis stenosis and esophageal reflux. Two patients died of tumor recurrence and metastasis witnin one year after operation, and the rest had disease-free survival until the end of follow-up.ConclusionFrom preliminary results of limited cases in this study, π-shaped esophagojejunal anastomosis in TLTG is a technically safe and feasible surgical procedure in treatment of gastric cancer.
ObjectiveTo analyze the risk factors affecting the postoperative ileus after total gastrectomy in elderly patients with gastric cancer. MethodsThe elderly patients with gastric cancer after total gastrectomy admitted to the Second Department of General Surgery of Shaanxi Provincial People’s Hospital from January 2015 to December 2020 were retrospectively collected and the postoperative ileus was analyzed. Meanwhile the risk factors affecting the postoperative ileus after total gastrectomy in the elderly patients with gastric cancer were analyzed using univariate and multivariate logtistic regression analyses. ResultsA total of 306 elderly patients with gastric cancer who met the inclusion and exclusion criteria of this study were collected, 33 (10.8%) of whom suffered the postoperative ileus after surgery. The results of multivariate logtistic regression analysis showed that the preoperative anemia [OR (95%CI)=2.740 (1.181, 6.356), P=0.019], preoperative complicated intestinal obstruction [OR (95%CI)=3.286 (1.208, 8.935), P=0.020], open operation [OR (95%CI)=3.753 (1.298, 10.848), P=0.015], and operative time ≥400 min [OR (95%CI)=3.902 (1.705, 8.925), P=0.001] increased the risk probability of postoperative ileus after total gastrectomy in the elderly patients with gastric cancer. ConclusionsAccording to the analysis results of this study, the preoperative anemia and complicated intestinal obstruction, as well as the adopted open surgery and operation time ≥400 min are the risk factors of postoperative ileus in elderly patients with gastric cancer after total gastrectomy. When total gastrectomy is chosen for elderly patients with gastric cancer, preoperative physical status needs to be adjusted, such as correcting anemia and removing preoperative intestinal obstruction. During operation, the operation modus should be prior to the minimally invasive surgery according to the individual conditions of elderly patients and the operation skills of surgeons should be improved so as to reduce postoperative ileus.
ObjectiveTo evaluate the safety and efficacy of transorally inserted anvil (OrVilTM) for laparoscopic total gastrectomy compared with open total gastrectomy.MethodsRetrospectively summarized the 285 gastric cancer patients from the Affiliated Hospital of Xuzhou Medical University between December 2012 and April 2018, of them 156 patients underwent laparoscopic total gastrectomy (being reconstructed by OrVilTM) via 129 patients underwent open total gastrectomy. Operation-associated parameters and postoperative complications were compared between the two groups.ResultsThe intraoperative blood loss was significantly less, proximal resection margin was significantly longer, and first ambulatory time, time to first flatus, time to fluid diet were significantly shorter in the laparoscopic total gastrectomy group (P<0.05). Whereas the total operative time, esophagojejunostomy time, numbers of dissected lymph nodes, time to remove drainage tube, length of postoperative hospital stay, and morbidity of postoperative complication (including anastomotic leakage, anastomotic stenosis, anastomotic bleeding, celiac and pleural effusion or infection) were not significantly different between the two groups (P>0.05).ConclusionOrVilTM is a technically safe and feasible surgical procedure for esophagojejunostomy in laparoscopic total gastrectomy.
