ObjectiveTo explore the clinical effect of keeping the pancreatic capsule in radical gastrectomy for early stage of gastric cancer. MethodsTwo hundreds and seven patients with early stage of gastric cancer who were treated in our hospital from Jan 2011 to December 2011 were enrolled prospectively, and were divided into experimental group (n=95) and control group (n=112). Patients in experimental group kept the pancreatic capsule in radical gastrec-tomy, but patients in control group didn't keep the pancreatic capsule. Comparison of the clinical effect between the 2 groups was performed. ResultsThe blood loss[(134.1±5.3) mL vs. (150.3±3.7) mL] and operation time[(76.4±5.7) min vs. (87.5±9.1) min]of experimental group were all lower or shorter than those of control group (P<0.05), but there were no significant difference between the 2 groups in incidence of total complication[7.37% (7/95) vs. 10.71% (12/112)], stomal leak[3.16% (3/95) vs. 4.46% (5/112)], and anastomotic stenosis[4.21% (4/95) vs. 6.25% (7/112)], P>0.05. All of the 207 patients were followed-up for 1-36 months, with the median time of 17.5 months. During the follow-up period, in experimental group, there were 30 patients suffered from recurrence, 23 patients suffered from metastasis, and 44 patients died, and the 1-and 3-year survival rates was 84.21% (80/95) and 53.68% (51/95) respectively, 1- and 3-year disease free survival rates was 80.00% (76/95) and 48.42% (46/95) respectively; in control group, there were 37 patients suffered from recurrence, 23 patients suffered from metastasis, and 49 patients died, and the 1-and 3-year survival rates was 85.71% (96/112) and 56.25% (63/112) respectively, 1-and 3-year disease free survival rates was 81.25% (91/112) and 49.11% (55/112) respectively. There were no significant difference in the 1-and 3-year survival rate, 1-and 3-year disease free survival rate (P>0.05). In addition, there were no significant difference in the survival and disease free survival situation (P>0.05). ConclusionsSurvival and disease free survival situation of keeping the pancreatic capsule in radical gastrectomy is similar with traditionally radical gastrectomy, but surgery of keeping the pancreatic capsule in radical gastrectomy has the advantages of less bleeding and shorter operation time, which is worthy of further study.
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 investigate the risk factors affecting the occurrence of infectious complications after radical gastrectomy for gastric cancer, and to establish a risk prediction Nomogram model. MethodsThe clinicopathologic data of 429 primary gastric cancer patients who underwent radical resection for gastric cancer at the Second Department of General Surgery of Shaanxi Provincial People’s Hospital between January 2018 and December 2020 were retrospectively collected to explore the influencing factors of infectious complications using multivariate logistic regression analyses, and to construct a prediction model based on the results of the multivariate analysis, and then to further validate the differentiation, consistency, and clinical utility of the model. ResultsOf the 429 patients, infectious complications occurred in 86 cases (20.05%), including 53 cases (12.35%) of pulmonary infections, 16 cases (3.73%) of abdominal infections, 7 cases (1.63%) of incision infections, and 10 cases (2.33%) of urinary tract infections. The results of multivariate logistic analysis showed that low prognostic nutritional index [OR=0.951, 95%CI (0.905, 0.999), P=0.044], long surgery time [OR=1.274, 95%CI (1.069, 1.518), P=0.007], American Society of Anesthesiologists physical status classification (ASA) grade Ⅲ–Ⅳ [OR=9.607, 95%CI (4.484, 20.584), P＜0.001] and alcohol use [OR=3.116, 95%CI (1.696, 5.726), P＜0.001] were independent risk factors for the occurrence of infectious complications, and a Nomogram model was established based on these factors, with an area under the ROC of 0.802 [95%CI (0.746, 0.858)]; the calibration curves showed that the probability of occurrence of infectious complications after radical gastrectomy predicted by the Nomogram was in good agreement with the actual results; the decision curve analysis showed that the Nomogram model could obtain clinical benefits in a wide range of thresholds and had good practicality.ConclusionsClinicians need to pay attention to the perioperative management of gastric cancer patients, fully assess the patients’ own conditions through the prediction model established by prognostic nutritional index, surgery time, ASA grade and alcohol use, and take targeted interventions for the patients with higher risks, in order to reduce the risk of postoperative infectious complications.
ObjectiveTo study and analyse the correlation between biologic behavior and clinical factors in gastric cancer.MethodsClinical and pathological study of carcinoma of stomach were retrospectively made in 1034 patients. ResultsIn this series,148 of 1034 patients (14.3%) were early gastric cancer.The frequency of lymph nodes metastasis was higher in proximal gastric cancer than distal (P＜0.0001).Similar frequency can also be seen in the tumor of larger diameter (P＜0.01),deeper invasion (P＜0.0001) and poor differentiation (P=0.004).Some difference in ages and sex of patients may be found on the invasion (P=0.003),differentiation (P＜0.0001),site (P＜0.001) and frequency of lymph nodes metastasis of the tumor (P=0.01).In multifactorial multivariate linear regression analysis,the site of tumor (P=0.003),diameter of tumor (P＜0.0001),depth of tumor infiltration (P＜0.0001) and the cell differentiation showed significant association with lymph node metastasis,in which the female patient had more lymph node metastasis than male (P＜0.001).Depth of tumor infiltration was the most important factor in lymph node metastasis.Numbers of lymph nodes resected were much more in total and distal gastrectomies than that in proximal gastrectomy (P＜0.0001). ConclusionThe results of this study suggest that radical gastrectomy with lymphadenectomy is necessary even in all stages of gastric cancer.
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 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.
With the swift evolution of bariatric and metabolic surgery, additional procedures building upon sleeve gastrectomy have consistently surfaced. Recent studies suggest that sleeve gastrectomy with jejunojejunal bypass (SG-JJB) yields superior short-term weight reduction outcomes compared to sleeve gastrectomy alone, with weight loss and glycemic control effects akin to Roux-en-Y gastric bypass, and without significant complications. As a result, SG-JJB is regarded as a safe and efficacious bariatric procedure, noted for its technical simplicity and reversibility, presenting substantial clinical utility. Nonetheless, high-quality, multicenter, large-sample, long-term follow-up randomized controlled trials are essential to further ascertain its long-term efficacy and safety, and to facilitate its standardized implementation. This article seeks to review the advancements in SG-JJB research, evaluate its effectiveness and safety in managing obesity and associated comorbidities, and explore its future developmental trajectory.
Objective To investigate the clinical application value of unsymmetrical four-port laparoscopic sleeve gastrectomy (LSG). Methods The clinical data of 114 patients with obesity who were admitted to Mianyang Central Hospital from June 2021 to May 2022 were retrospective analyzed. All the 114 patients underwent unsymme-trical four-port LSG, and were observed their surgical and postoperative conditions, complications and follow-up the patient’s esthetic satisfaction of wounds at 3 months after surgery. Results All 114 patients underwent unsymmetrical four-port LSG successfully, without conversion to open surgery. The operative time was 68–160 min, average (104.2±26.1) minutes; volume of intraoperative blood loss was 2–50 mL, average (10.7±7.6) mL; the duration of postoperative hospital stay was 3–6 d, average (4.0±0.7) days. Of the 114 patients, 8 patients (7.0%) had fat liquefaction of wounds, 68 patients (59.6%) had postoperative nausea and vomiting in the 24 hours after operation, and all patients had no serious complications such as gastrointestinal bleeding, intraperitoneal hemorrhage, or gastric leakage. One hundred and fourteen patients were followed-up for 3–14 months, with a median follow-up of 6 months. Forty patients (35.1%) had hair loss, 3 patients (2.6%) had mild anemia. Of the 114 patients, 2 (1.8%) were dissatisfied with the cosmetic effects of wounds, 64 (56.1%) were satisfied, and 48 (42.1%) were very satisfied. The satisfaction rate was 98.2% (112/114). Conclusion The unsymmetrical four-port LSG is safe and feasible, it does not affect esthetic satisfaction of wounds.
Objective To explore method of jejunum nutrition tube implantation in total laparoscopic radical gastrectomy for distal gastric cancer (GC). Methods The clinical data of 30 patients with distal GC underwent the total laparoscopic radical gastrectomy from October 2017 to March 2018 in the Departmeng of Tumor Surgery, Lanzhou University Second Hospital were retrospectively analyzed, the total laparoscopic radical distal gastrectomy were performed in all the patients and the jejunum nutrition tube were implanted during the operation. Results Thirty patients with distal GC were successfully treated with the total laparoscopic radical gastrectomy and the jejunum nutrition tubes were implanted into under the total laparoscopy through the intraoperative guidance by the gastric tube, firstly fastening the nutrition tube to the gastric tube in vitro, and then separating them in vivo, finally the nutrition tube was smoothly implanted into the jejunum under the direct vision. The implantation time was 10 to 15 min with an average of 13.5 min. The jejunal nutrition tube retention time was 5 to 7 d with an average of 6 d. There were no complications such as the bleeding, anastomotic leakage, anastomotic obstruction, stenosis, intestinal leakage, intestinal obstruction, and other complications after the operation in the 30 patients. Conclusions Method of jejunum nutrition tube implantation in total laparoscopic radical gastrectomy for distal GC is easy to be performed. Intraoperative and postoperative complications are few. It provides a favorable guarantee for improving postoperative nutritional status of patient with distal GC.
ObjectiveTo explore the evaluation value of preoperative multislice spiral computed tomography angiography (MSCTA) for normative radical gastrectomy. MethodsThe anatomic distributions of celiac trunk and its three branches and their tributaries (common hepatic artery, right hepatic artery, left hepatic artery, splenic artery, and left gastric artery) of 86 patients with gastric cancer were comprehended by preoperative MSCTA, which were verified during the surgery. Simultaneously preoperative TNM staging was evaluated by MSCTA, which compared with postoperative pathological results. ResultsThe accuracy rate of preoperative MSCTA evaluating the distribution of celiac trunk and its three branches and their tributaries was 100%. Abnormal hepatic arteries were found in 22 cases by MSCTA, the mutation rate was 25.58%. Abnormal right hepatic arteries were found in 11 cases (12.79%), abnormal left hepatic arteries in 7 cases (8.14%), both abnormal right and left hepatic arteries in 1 case (1.16%), and abnormal common hepatic arteries in 3 cases (3.49%). Straight splenic arteries were found in 24 cases (27.91%), slightly curved splenic arteries in 44 cases (51.16%), and significantly curved splenic arteries in 18 cases (20.93%). Compared with postoperative pathological results, the accuracy rates of preoperative MSCTA evaluating gastric cancer T, N, and M staging were 75.58%（65/86）, 74.42%(64/86), and 91.86%(79/86), respectively. ConclusionsPreoperative MSCTA is an objective way to assess the distributions of celiac artery trunk and related tributaries of patients with gastric cancer. Also, it is an accurate method to evaluate the preoperative TNM stage of gastric cancer, which can help to make an individual operative plan and avoid the intraoperative injury of the artery.
