Objective To formulate an individualized evidence-based treatment for a patient with severe obesity. Methods According to the PICO (patient intervention comparison outcome) principle, the evidence was collected and critically assessed after the clinical issues were put forwarded. The patient’s preference was also taken into account in the decision making process. Results Nine clinical guidelines, eight systematic reviews or meta-analyses and three randomized controlled trials (RCTs) were included. According to the data from the included studies and patient’s special condition, a reasonable surgical treatment regime was made to reduce the weight, relieve all kinds of complications and improve the life quality which were all regarded as the expected target. After one year’s follow-up, the patient’s weight reduced by 20 kg, and some obesity-related co-morbidities such as sleep apnea syndrome and hyperlipoidemia were also improved significantly. Conclusion The laparoscopic adjustable gastric band is an effective operation for severely obese individuals. This procedure can not only achieve weight loss, but also improve some obesity-related co-morbidities.
ObjectiveTo explore the value of modified subcutaneous lumbar spine index (MSLSI) as a predictor for short-term effectiveness of transforaminal lumbar interbody fusion (TLIF) in treatment of lumbar degenerative disease (LDD).MethodsBetween February 2014 and October 2019, 450 patients who were diagnosed as LDD and received single-segment TLIF were included in the study. Based on the MSLSI measured by preoperative lumbar MRI, the patients were sorted from small to large and divided into three groups (n=150). The MSLSI of group A was 0.11-0.49, group B was 0.49-0.73, and group C was 0.73-1.88. There was no significance in gender, age, disease duration, diagnosis, surgical segment, and improved Charlson comorbidity index between groups (P>0.05). There were significant differences in the subcutaneous adipose depth of the L4 vertebral body and body mass index (BMI) between groups (P<0.05). The operation time, intra-operative blood loss, length of incision, drainage tube placement time, drainage volume on the 1st day after operation, drainage volume on the 2nd day after operation, total drainage volume, antibiotic use time after operation, walking exercise time after operation, hospital stay, the incidences of surgical or non-surgical complications in the three groups were compared. Pearson correlation analysis was used to analyze the correlation between MSLSI and BMI, and partial correlation analysis was used to study the relationship between MSLSI, BMI, improved Charlson comorbidity index, subcutaneous adipose depth of the L4 vertebral body and complications. The Receiver Operating Characteristic (ROC) curve was used to evaluate the value of SLSI and MSLSI in predicting the occurrence of complications after TLIF in treatment of LDD.ResultsThere was no significant difference in operation time, length of incision, antibiotic use time after operation, walking exercise time after operation, drainage tube placement time, drainage volume on the 1st day after operation, drainage volume on the 2nd day after operation, and total drainage volume between groups (P>0.05). The amount of intra-operative blood loss in group C was higher than that in groups A and B, and the hospital stay was longer than that in group B, with significant differences (P<0.05). Surgical complications occurred in 22 cases (14.7%), 25 cases (16.7%), and 39 cases (26.0%) of groups A, B, and C, respectively. There was no significant difference in the incidence between groups (χ2=0.826, P=0.662). The incidences of nerve root injury and wound aseptic complications in group C were higher than those in groups A and B, and the incidence of nerve root injury in group B was higher than that in group A, with significant differences (P<0.05). There were 13 cases (8.7%), 7 cases (4.7%), and 11 cases (7.3%) of non-surgical complications in groups A, B, and C, respectively, with no significant difference (χ2=2.128, P=0.345). There was no significant difference in the incidences of cardiovascular complications, urinary system complications, central system complications, and respiratory system complications between groups (P>0.05). There was a correlation between MSLSI and BMI in 450 patients (r=0.619, P=0.047). Partial correlation analysis showed that MSLSI was related to wound aseptic complications (r=0.172, P=0.032), but not related to other surgical and non-surgical complications (P>0.05). There was no correlation between BMI, improved Charlson comorbidity index, subcutaneous adipose depth of the L4 vertebral body and surgical and non-surgical complications (P>0.05). ROC curve analysis showed that the area under ROC curve (AUC) of MSLSI was 0.673 (95%CI 0.546-0.761, P=0.025), and the AUC of SLSI was 0.582 (95%CI 0.472-0.693, P=0.191). ConclusionMSLSI can predict the short-term effectiveness of TLIF in treatment of LDD. Patients with high MSLSI suffer more intra-operative blood loss, longer hospital stay, and higher incidence of nerve root injury and postoperative incision complications.
A lot of evidence-based medical evidence has shown that laparoscopic Roux-en-Y gastric bypass (LRYGB) is a durable and effective method for obesity and diabetes, and can significantly improve a series of obesity-related metabolic complications. This guideline provides a detailed description of the main operating steps and technical points of the symmetric three-port LRYGB, including posture layout, trocar position selection, liver suspension, gauze exposure, production of small gastric sacs, gastrojejunal anastomosis and production of biliary pancreatic branches, entero-enteric side to side anastomosis, closure of gastrointestinal anastomosis and mesenteric hiatus, greater omentum coverage, and closure of incisions. The purpose is to standardize the operating process of the symmetrical three hole method of LRYGB, providing standardized surgical operation references for clinical doctors in the field of obesity metabolic surgery.
ObjectiveTo understand the present situation and effect of da Vinci robot in the treatment of obesity.MethodThe literatures about the application of da Vinci surgical robot in metabolic surgery for weight loss were reviewed.Resultsda Vinci surgical robot was a minimally invasive surgical system in recent years. Because of its unique structure, it broke through the limitations of traditional laparoscopic surgery, such as lack of field of vision, two-dimensional imaging, unstable lens, limited range of movement, and so on. It provided a solution way for metabolic surgery for weight loss with narrow operation space and high technical difficulty. At present, there were differences in operation time and postoperative complications between da Vinci surgical robot and laparoscopic weight loss.ConclusionsIn recent years, da Vinci surgical robot has been widely used in metabolic surgery for weight loss. It not only overcomes many limitations of laparoscopic assisted weight loss surgery, but also it is safe, feasible, and has a similar clinical effect. It provides a new choice for metabolic surgery for weight loss.
ObjectiveTo compare the curative effect of biliopancreatic diversion with duodenal switch (BPD/DS) with different gastrointestinal anastomotic position in the rat with obese diabetes. MethodsThe obese diabetic rat models were induced by high-fat feeding for 1 month combined with intraperitoneal injection of low-dose streptozotocin (35 mg/kg), then which were divided into modified BPD/DS (M-BPD/DS), BPD/DS, sleeve gastrectomy (SG), and sham operation (SO) groups according to the operation performed. Eight rats in each group were randomly selected for following experimental observation. The situation of weight loss, glucose reduction, nutrition, and esophagitis were compared among 4 groups, especially between the M-BPD/DS and BPD/DS groups. Results① The body mass and food intake of rats in the M-BPD/DS and BPD/DS groups at 1–4 month(s) after operation (except food intake at the 4th month) were lower than those in the SO group (P<0.05), but it was found that the food intake of the M-BPD/DS group was higher than that of the BPD/DS group at the first month after operation (P<0.05). ② The fasting blood glucose levels of the M-BPD/DS and BPD/DS groups were lower than those of the SO group (P<0.05) and were lower than those before the operation (P<0.05), but which had no statistical difference between the M-BPD/DS and BPD/DS groups (P>0.05). ③ The area under receiver operating characteristic curve (AUC) of blood glucose level by oral glucose tolerance test, insulin tolerancetest (ITT), and the homeostasis model assessment-insulin resistance index at the 1st and 4th month after operation of the M-BPD/DS and BPD/DS groups were lower of the SO group (P<0.05) and before operation (P<0.05), but which had no statistical difference between the M-BPD/DS and BPD/DS groups (P>0.05). It was also found that the AUCs of ITT values at the 4th month after operation of the M-BPD/DS and BPD/DS groups were higher than those of the 1st month after operation (P<0.05). ④ The AUCs of the glucagon like peptide-1 (GLP-1) levels at the 1st and 4th month after operation of the M-BPD/DS and BPD/DS groups were higher than those of the SO group (P<0.05), while the AUCs of the insulin index were lower than those of the SO group (P<0.05) at 1 and 4 months after operation. At the 1st and 4th month after operation, the AUCs of the GLP-1 were higher and the insulin were lower than those before operation (P<0.05) in the M-BPD/DS and BPD/DS groups, which had no statistical difference between the M-BPD/DS and BPD/DS groups (P>0.05). ⑤ The albumin, calcium, and ferrum at the 1st and 4th month after operation of the M-BPD/DS and BPD/DS groups were statistically lower than those of the SO group (P<0.05) and lower than those before operation (P<0.05). ⑥ The thickness of esophageal squamous epithelium and rate of nipple elongation of the M-BPD/DS group were lower than those of the BPD/DS group (P<0.05). ConclusionThe results of this experiment suggest that moving the gastrointestinal anastomosis above the pylorus simplifies the operationof BPD/DS without affecting its weight loss and glucose lowering effect , and may have a protective effect on the esophagus.
ObjectiveTo compare and analyze the therapeutic effect of robotic and laparoscopic radical resection of rectal cancer for obese patients with rectal adenocarcinoma. MethodsThe retrospective cohort study was conducted. The clinicopathologic data of 217 obese patients with rectal adenocarcinoma who were treated in the First Affiliated Hospital of Zhengzhou University from October 2017 to January 2020 were collected, 104 patients received radical resection of rectal cancer assisted by Da Vinci robotic surgical system and were assigned to the robot group, 113 patients underwent laparoscopic-assisted radical resection of rectal cancer and were assigned to the laparoscope group. The perioperative indexes, pathological examination, and postoperative recovery of urogenital function were compared. ResultsThere were no significant differences between the two groups in the gender, age, body mass index, distance from lower edge of tumor to anal edge, tumor diameter, American Association of Anesthesiologists classification, preoperative complications, preoperative carcinoembryonic antigen level, tumor differentiation, and TNM stage (P>0.05). The operations were successfully completed in all patients and there was no conversion to laparotomy and perioperative death. There were no significant differences between the two groups in the operation time, first exhaust time, first eating liquid food time, first getting out of bed activity time, drainage tube placement time, prophylactic stoma rate, and postoperative complications (P>0.05). The intraoperative blood loss and total hospital stay in the robot group were less than those of the laparoscope group (P<0.05). The International Prostate Symptom Score of the robot group was lower than that of the laparoscope group at 3, 6, and 12 months after operation (P<0.05). The International Index of Erectile Function-15 score of male patients and Female Sexual Function Index-19 score of female patients in the robot group were higher than those in the laparoscope group at 3, 6, and 12 months after operation (P<0.05). ConclusionsRobotic surgery is safe and effective in treatment of obese patients with rectal adenocarcinoma. Compared with laparoscopic surgery, robotic surgery could benefit patients more in protecting postoperative genitourinary function.
ObjectiveTo systematically review the efficacy of auricular pressure therapy for simple obesity in adult. MethodsWe electronically searched databases including The Cochrane Library (Issue 4, 2015), PubMed, Web of Science, MEDⅡNE (Ovid), CNKI, VIP, CBM and WanFang Data databases to collect randomized controlled trials (RCTs) of auricular pressure therapy for simple obesity from inception to March 2015. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.3 software. ResultsA total of 17 RCTs involving 1 246 patients were included. The results of meta-analysis showed that:(1) Compared with the blank control group, the auricular pressure therapy group was superior in weight reduction (MD=-2.50, 95%CI -3.53 to -1.47, P<0.01), BMI reduction (MD=-1.50, 95%CI -2.52 to -0.48, P=0.004), and waist circumference reduction (MD=-3.20, 95%CI -4.38 to -2.02, P<0.01); (2) Compared with the placebo control group, the auricular pressure therapy group was superior in weight reduction (MD=-1.39, 95%CI -1.46 to -1.31, P<0.01), BMI reduction (MD=-0.65, 95%CI -0.91 to -0.38, P<0.01), body fat percentage reduction (MD=-0.58, 95%CI -0.67 to -0.49, P<0.01), and waist circumference reduction (MD=-2.34, 95%CI -4.23 to -0.46, P=0.01); (3) There were no significant differences between the auricular pressure therapy group and the body acupuncture group in weight reduction, BMI reduction, and waist circumference reduction (all P values >0.05); (4) Compared with the body acupuncture group, the auricular pressure combined with body acupuncture group was superior in BMI reduction (MD=-1.67, 95%CI -2.48 to -0.85, P<0.01); (5) Three RCTs reported adverse reactions including cyanotic skin, erythema near auricular pressure etc., and all adverse reactions were mostly mild and recovered after treatment. ConclusionCurrent evidence indicates that auricular pressure therapy for simple obesity is superior to placebo and blank control, but similar to body acupuncture; the auricular pressure combined with body acupuncture is superior to body acupuncture alone in BMI reduction. Due to the limited quantity and quality of included studies, more high quality studies are needed to verify the above conclusion.
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.
ObjectiveTo systematically review the clinical effects of green tea extracts on simple obesity. MethodsSystematic retrieval were conducted in PubMed, The Cochrane Library (Issue 8, 2012), CNKI, VIP, CBM, and WanFang Data to collect the randomized controlled trials (RCTs) on green tea extracts in treating patients with simple obesity. According to the inclusion and exclusion criteria, two reviewers independently screened literature, extracted data, and assessed the methodological quality of the included studies. Meta-analysis was then performed using RevMan 5.0. ResultsA total of 11 RCTs involving 693 patients were included. Results of meta-analysis displayed that compared with the control group, patients in the green tea extracts group significantly had a obvious decrease of body mass (WMD=-0.32, 95%CI-0.46 to-0.17, P < 0.000 1) as well as body mass index (BMI) (WMD=-0.07, 90%CI-0.09 to-0.05, P < 0.000 01) with significant differences. ConclusionCurrent evidence shows that, green tea extracts could effectively treat simple obesity.
ObjectiveTo summarize the mechanism of effects of laparoscopic sleeve gastrectomy (LSG) on gastroesophageal reflux disease (GERD) and the research progress of LSG in combination with fundoplication on obesity with GERD. MethodThe literatures of studies relevant to relation between LSG and GERD and effect of LSG combined with fundoplication on obesity accompanying GERD at home and abroad were searched and reviewed. ResultsAlthough there was considerable disagreement over the effect of LSG on GERD, the evidence showed that the LSG alone might worsen the existing GERD or promote new GERD, which mainly due to the destruction of the lower esophageal sphincter, deactivation of His angle, elevated intragastric pressure, and shape of sleeve stomach. Currently, the LSG in combination with fundoplication had been gradually applied in the clinical treatment of obese patients with GERD. And the short-term results of follow-up showed that the effects of weight loss and anti-reflux could be obtained, which needed to be evaluated by more studies and longer follow-up. ConclusionsThere is a risk of worsening existing GERD or promoting new GERD after LSG surgery. The LSG in combination with fundoplication is safe and feasible, which not only makes up for the adverse effects of LSG only on GERD after surgery, but also achieves the same similar effect of weight loss as LSG, providing a new choice for obese patients with GERD.
