ObjectiveTo explore a surgery of effective weight loss concentrating on gut hormone release. MethodsWistar rats were fed with high-fat diet for inducing obesity and which randomly divided into sleeve gastrectomy plus decent jejunoileal bypass (SJB) group (n=12), sleeve gastrectomy (SG) group (n=12), and sham operation (SO) group (n=11), the body weight reduction, food intake, plasma ghrelin level, and glucagon like peptide-1 (GLP-1) level were compared among three groups. ResultsThere were no differences of the body weight and food intake before operation among three groups (Pgt;0.05). Compared with the SO group, the body weight descended and the food intake decreased obviously on 1-8 weeks after operation in the SJB group (Plt;0.05), the body weight of rats on 1-8 weeks after operation in the SJB group significantly descended as compared with the SG group (Plt;0.05), and the food intake of rats on week 3, 6, 7, and 8 in the SJB group signicantly decreased as compared with the SG group (Plt;0.05). There were no differences of the levels of the plasma ghrelin and GLP-1 before operation among three groups (Pgt;0.05). Compared with SO group, the plasma ghrelin level decreased and the GLP-1 level increased in the SJB group and the SG group, meanwhile the SJB group significantly decreased level of plasma ghrelin and elevated level of plasma GLP-1 as compared with the SG group on week 8 after operation(Plt;0.05). ConclusionThe data demonstrate that SJB could represent an effective way of losing weight by interfering with food intake and obesity related hormone levels.
Laparoscopic sleeve gastrectomy (LSG) is an effective and lasting method for treating obesity, type 2 diabetes and other obesity related metabolic diseases. The symmetrical three-port LSG has been proven to be a simple, safe, and effective surgical procedure. However, China still lacks standardized surgical operation guidelines for this method. This guideline provides a detailed description of the various steps and key details of the symmetrical three-port LSG, aiming to standardize and normalize the symmetrical three-port LSG in the bariatric and metabolic field in China, and to provide standardized surgical procedures for clinical surgeons in this field.
Motor function was investigated by constant perfusion manometry in the Roux limb of ten patients who had undergone total gastrectomy and Roux-en-Y anastomosis. Results showed that in the fasting state, the migrating motor complex (MMC) was comletely absent, retrograde in direction or bursts of nonphasic pressure activity. Reduced motor activity patterns occurred after the meal in some patients. Four patients failed to convert fasting state into the feeding state. Total gastrectomy with Roux-en-Y anastomoses provakes a relatively severe distubance in motor function, which could contribute to postoperative upper abdominal distress.
Objective To summarize and analyze the application value of triple stomach shaping technique in laparoscopic sleeve gastrectomy (LSG). Methods The clinical data of patients undergoing simple LSG with triple stomach shaping technique carried out by the General Surgery Obesity and Metabolic Diseases Center of Chengdu Third People’s Hospital from January to December 2021 were retrospectively collected, recording the operative time and the occurrence of recent complications such as postoperative nausea/vomiting, gastric leakage, bleeding, obstruction/torsion within 30 days after operation. Results A total of 966 patients were collected, including 294 males and 672 females. The age was 16–65 years, average age was (32.8±8.6) years. Body mass index was 27.5–47.2 kg/m2, average was (34.2±3.5) kg/m2. All operations were successfully completed without conversion to laparotomy. The operative time was 45–170 min, average was (100.2+33.4) minutes. Postoperative nausea/vomiting occurred in 484 cases (50.10%), bleeding in 2 cases (0.21%, intraperitoneal bleeding in 1 case, intragastric bleeding in 1 case), gastric leakage in 1 case (0.10%, grade B leakage), and no perioperative death occurred. Hospitalization time was 4–24 d, average was (7.55±2.47) d. Two patients (0.21%) were hospitalized again due to nausea and vomiting within 30 days after operation, they were relieved and discharged after conservative medical treatment. Conclusion Triple gastric shaping technology is more physiological, safe and suitable for promotion.
In perioperation period, the dynamic changes of solubla interleulcin-2 receptor (sIL-2R) in serum were determined by ELISA in 60 patients with gastric cancer (GC), and then was compared with those of 30 normal individuals and 40 selective patients who necieved common abdominal surgery. Results: At the day before and ten days after operation, the sIL-2R of patients with GC was higher than that of normal individual. But twenty days after operation, the sIL-2R reduced to as normal level. Conclusion: As a immunodepressive index, the sIL-2R of patients with GC was increased obviously, and after radical gastrectomy, it decreased gradually. So by determining sIL-2R, we can evaluate the immunologic function of patientswith GC.
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.
ObjectiveTo evaluate the effect of glutamineenhanced enteral nutritional support on elder patients after total gastrectomy. MethodsA total of eightyfour cases of elder patients receiving total gastrectomy were included in this study from February 2008 to August 2010. The patients were randomly divided into three groups: glutamineenhanced enteral nutrition (Gln) group, enteral nutrition (EN) group and parenteral nutrition (PN) group. The complications and hospital stay after operation were compared, and the levels of serum total protein, albumin, proalbumin， and transferrin of patients were measured before operation, on 2 d and 10 d after operation, respectively. Furthermore, the percentage of CD4 and CD8 T cells, CD4/CD8 ratio， and the levels of serum IgM and IgG of patients in peripheral blood before and after operation were detected. ResultsNutritional therapy was successfully performed in patients of three groups. The anal exhaust time and hospital stay after operation of patients in Gln group and EN group were significantly lower than those in PN group (Plt;0.05). The difference of postoperative complications and digestive tract symptoms of patients in three groups was not obvious (Plt;0.05). Anastomotic fistula occurred in one patient of PN group on 6 d after operation and was cured by conservative treatment for 54 d. The difference of total protein, albumin, proalbumin, and transferrin levels of patients in three groups before operation was not significant (Pgt;0.05), and these indexes fell dramatically on 2 d after operation and lower than before operation (Plt;0.05), although the intergroup difference was not statistically significant (Pgt;0.05). On 10 d after operation, all indexes recovered in different extent, while those data in Gln group and EN group were significantly higher than those on 2 d after operation (Plt;0.05). The levels of total protein, albumin, and proalbumin of patients in Gln group and EN group were markedly higher than those in PN group (Plt;0.05), although there was no difference between the former groups (Pgt;0.05). The difference of several immunological parameters of patients in three groups before operation was not significant (Pgt;0.05). On 10 d after operation, the percentage of CD4 and CD8 T cells, CD4/CD8 ratio, and the levels of serum IgM and IgG of patients in Gln group returned and even exceeded the preoperative results, which were significantly higher than those in EN group and PN group other than IgM (Plt;0.05). The postoperative results of all parameters except IgG in EN group were significantly lower than preoperative results in patients of EN group and PN group (Plt;0.05). ConclusionsIt is safe and feasible to elder patients who had received total gastrectomy and perioperative glutamine-enhanced nutritional support, which can improve nutrition and immune status, promote the recovery and reduce the duration of hospital stay, and nutritiional support after total gastrectomy is one of the optimal choices for these patients.
ObjectiveTo investigate the clinical value of the C-reactive protein (CRP) ratio (CRP value on postoperative day 3/day 1) as an early predictor of postoperative severe complication after laparoscopic gastrectomy (LG) for gastric cancer.MethodsThis retrospective study examined the relationship between the occurrence of severe complication and the CRP ratio of 259 gastric cancer patients, who underwent LG in the Department of General Surgery of General Hospital of Fuxin Mining Industry Group of Liaoning Health Industry Group from January 2015 to January 2020. According to Clavien-Dindo (CD) grading system, gastric cancer patients were divided into the severe postoperative complication group (n=41, 15.8%) and the non-severe postoperative complication group (n=218, 84.2%). The relationship between CRP ratio and clinicopathologic characteristics of patients and the predictive value of CRP ratio for severe complication were analyzed.ResultsThe optimal cutoff value of CRP ratio of 2.2 offered 63.2% sensitivity, 91.0% specificity, 70.7% positive predictive value, and 85.8% negative predictive value for severe postoperative complication. The area under the receiver operating characteristic curve was 0.766. There had distinct differences (P<0.05) on body mass index, preoperative comorbidity, type of surgery, T stage, and TNM stage between the high CRP ratio group (CRP ratio >2.2, n=60) and the low CRP ratio group (CRP ratio ≤2.2, n=199). Logistic regression showed that preoperative comorbidity [OR=3.624, 95%CI (1.191, 11.206), P=0.023], later of TNM stage [OR=9.037, 95% CI (1.729, 47.226), P=0.009], and CRP ratio >2.2 [OR=20.473, 95%CI (7.948, 52.737), P<0.001] were independent risk factors for postoperative severe complication after LG.ConclusionThere must to be paid enough attention to the CRP ratio >2.2 on the day 1 and 3 after LG, it suggests that there might be a risk of severe postoperative complications.
ObjectiveTo compared weight loss and metabolic improvement effects of laparoscopic sleeve gastrectomy (LSG) in treatment of obese males and females. MethodsAccording to the inclusion and exclusion criteria, the obese patients were retrospectively collected, who underwent LSG from January 2020 to June 2021 in the Affiliated Hospital of Xuzhou Medical University, and there were complete preoperative data and postoperative follow-up data at month 1, 3, 6, and 12. The weight loss and metabolic improvement effects of obese males and females were compared, as well as the remissions of diabetes and hyperlipidemia at the 12th month after surgery were observed. ResultsA total of 129 eligible obese patients were included, including 44 obese males and 85 obese females. The preoperative body mass index (BMI), fasting blood glucose (FBG) level, and insulin level of the obese males were higher than those of the obese females (P<0.05). ① Weight loss effect after LSG: For both obese males and females, the change value (Δ) of BMI (all change values of the indexes were the difference between preoperative and postoperative value in this study), the percentage of excess body weight loss (EWL%), and percentage of total body weight loss showed continuous upward trends within the observation time range (P<0.05). And it was found that the obese males’ ΔBMI was higher than that of the obese females at the 1st and 3rd month after surgery (P<0.05), and the EWL% of the obese males was lower than that of the obese females at the 3rd, 6th, and 12th month after operation (P<0.05). ② Metabolic improvement effect after LSG: Blood glucose and lipid metabolism indicators in both male and female patients（ΔFBG, ΔINS, ΔHbA1c, ΔTC and ΔTG) changed the fastest at 1 month after operation, and the change became flat after 3 months, except for males ΔTC index (P>0.05), the overall difference between male and female patients at each time point after operation was statistically significant (P<0.05). After operation, the ΔFBG (at the 1st, 3rd, 6th, and 12th month) and Δinsulin (at the 3rd, 6th, and 12th month) in the obese males were higher than those in the obese females (P<0.05). The remission rates of diabetes and hyperlipidemia in the obese males and females at the 12th month after surgery were both higher, but there was no significant difference between the two groups [64.7% (11/17) versus 81.0% (17/21), χ2=0.578, P=0.447; 73.9% (17/23) versus 84.4% (27/32), χ2=0.378, P=0.539]. ConclusionsFrom the results of this study, LSG is an effective method in treatment of obesity and its complications for both males and females. Bariatric surgery should be suggested to perform as soon as possible for obese males with poor metabolic status.
Objective To explore the effect and mechanism of sleeve gastrectomy （SG） for type 2 diabetes mellitus （T2DM） in Goto-Kakizaki （GK） rats. Methods Thirteen male GK rats at 12 weeks of age were randomly divided into SG group （n=7） and sham operation group （SO group， n=6）， receiving SG surgery and sham operation respectively.Body weight， food intake in 24hours， fasting plasma glucose， plasma glucagon-like peptide-1 （GLP-1）， and plasma Ghrelin of rats in 2 groups were measured or tested before operation， 1， 4， 10， and 26 weeks after operation. In 10 weeks after operation， fecal energy content of rats in 2 groups was tested， in addition， oral glucose tolerance test （OGTT） and insulin tolerance test （ITT） were performed to investigate the glucose tolerance and insulin sensitivity. Results ①Body weight：there were no significant difference on body weight between the 2 groups （P＞0.05）. Compared with time point of before operation， the body weight of both 2 groups decreased in 1 week after operation （P＜0.01）， but increased in 10 weeks and 26 weeks （P＜0.01）. ②Food intake in 24 hours：compared with SO group， the food intake of SG group were lower in 4 weeks and 10 weeks after operation （P＜0.05）. Compared with time point of before operation， the food intake of SG group were lower in 1， 4， and 10 weeks after operation （P＜0.05）， but lower only in 1 week in SO group （P＜0.05）. ③Value of fasting glucose：compared with SO group， the value of fasting glucose in SG group were lower after operation （P＜0.01）. Compared with time point of before operation， the value of fasting glucose of SG group were lower after operation （P＜0.01）， but decreased in 1 week only in SO group （P＜0.01）. ④Level of serum GLP-1：compared with SO group， the levels of serum GLP-1 in SG group were higher in 4， 10， and 26 weeks after operation （P＜0.05）. Compared with time point of before operation， the levels of serum GLP-1 in SG group were higher in 4， 10， and 26 weeks after operation （P＜0.05）， but levels of serum GLP-1 in SO group didn’t change significantly （P＞0.05）. ⑤Level of serum Ghrelin：compared with SO group， the levels of serum Ghrelin in SG group were lower at alltime points after operation （P＜0.01）. Compared with time point of before operation， the levels of serum Ghrelin in SGgroup were lower at all time points after operation （P＜0.001）， but levels of serum Ghrelin in SO group didn’t change significantly （P＞0.05）. ⑥Areas under curves （AUC）：the AUC of OGTT and ITT test in SG group were both lower than those of SO group （P＜0.01）. Conclusion SG surgery can induce the level of fasting plasma glucose， and canimprove glucose tolerance and insulin sensitivity with significant changes of levels of plasma GLP-1 and Ghrelin， sugg-esting that SG surgery may be a potential strategy to treat patient with T2DM but without obesity or insulin resistance.
