ObjectiveTo summary the standard treatment for early gastric cancer.
MethodsThe current early gastric cancer treatment guidelines around the world were analyzed and the standardized treatment patterns for early gastric cancer were concluded.
ResultsThe accurate preoperative evaluation for early gastric cancer is the basis of standardized treatment which can be divided into staging evaluation and histological evaluation.The staging evaluation is focused on the gastric wall invasion and lymph node involvement of the tumor while the histologic evaluation emphasize the histological type and grading of the tumor.According to the precise evaluation for early gastric cancer, endoscopic surgery, laparoscopic surgery, open surgery, and multimodal therapy can be applied individually to the patients.Different treatment methods have their indications, but the indications of the therapies in different guidelines are suggested with slight differences.
ConclusionIn clinical practice, the choice of treatment should be made with comprehensive consideration of diagnosis and individual characteristics of patients to achieve the most benefit on prognosis.
Objective To study the clinical diagnosis and treatment of juxtapapillary duodenal diverticula with biliary deseases.Methods Eighteen duodenal diverticulum treated in our department in recent 5 years were retrospectivly analyzed, especially investigated the postcholecystectomy cases whose symptoms were continuing existence after operatoins. Articles about the surgical treatment were reviewed. Results The total of 18 duodenal diverticulum with 17 cases of juxtapapillary duodenal diverticulum were included in this study. The ages of 12 cases were over 50 years old. Sixteen cases(88.89%) presented biliary stones. Seven cases once had performed cholecystectomy or cholecystectomy plus choledochotomy,but symptoms persisted after operations. The duodenal diverticulum were found by endoscopic retrograde cholangiopancreatography (ERCP) and hypotonic duodenography. Sixteen patients underwent surgical treatment with good effect. Conclusion The juxtapapillary duodenal diveticula has the close relationship with biliary stones. ERCP and hypotonic duodenogrphy are the most reliable methods to get the correct diagnosis. In case of recurrent common bile duct stones after operations or persisting billiary symptoms after cholecystectomy, the coexistence of juxtapapillary duodenal diverticulum should be ruled out. The surgical treatment is only considered for the duodenal diverticulum with complication.
Objective To summarize the clinical significance of endoscopic treatment for obstructive jaundice. Methods The recently published literatures in domestic and abroad about endoscopic treatment for obstructive jaundice were reviewed. Results The results of endoscopic treatment for bile duct stones and bile duct surgery for biliary stricture had the same outcome. The endoscopic treatment could identify bile duct and duodenal periampullary tumors and lesions. Conclusion Endoscopic treatment for obstructive jaundice is a safe and effective method.
ObjectiveTo evaluate the application of dexmedetomidine for moderate sedation in patients undergoing endoscopic ultrasonography.MethodsPatients who were planned to undergo endoscopic ultrasonography in West China Hospital of Sichuan University from February to June 2019 were randomly divided into dexmedetomidine group (trial group) and propofol group (control group). The basic conditions, success rate of endoscopic ultrasound diagnosis and treatment, sedation-related adverse events, implementation of airway management, postoperative comfort evaluation and endoscopic physician satisfaction score of the two groups were compared.ResultsA total of 120 patients were eventually enrolled, 60 in each group. There was no significant difference in the basic conditions of the two groups (P>0.05). The success rate of endoscopic ultrasound diagnosis and treatment in two groups were 100%. There was no significant difference in the incidence of bucking, apnea and bradycardia between the two groups (P>0.05). The incidence of hypotension (15.0% vs. 31.7%), hypoxemia (6.7% vs.20.0%) in the trial group was lower than those in the control group, the differences were statistically significant (P<0.05). The proportion of patients in the trial group who performed airway management was lower than that in the control group (1.7% vs. 28.3%), and the difference was statistically significant (P<0.05). There was no significant difference in postoperative pain score, the first time to get out of bed and postoperative 15-item quality of recovery questionnaire score between the two groups (P>0.05). The incidence of nausea and vomiting at 6 hours after operation (48.3% vs. 3.3%) and 24 hours after operation (10.0% vs. 0.0%) and the time required for recovery of gastrointestinal function ［(201.4±178.4) vs. (148.5±75.7) min］ in the trial group were higher than those in the control group (P<0.05). The median (the lower and upper quartile) of comfort score of patients and satisfaction score of endoscopic physicians were 8 (6, 10) and 8 (7, 9) in the trial group, respectively, and were 10 (9, 10) and 9 (8, 10) in the control group, with statistically significant differences (P<0.05).ConclusionModerate sedation with dexmedetomidine could provide good sedative and analgesic effects in endoscopic ultrasonography. It has little effect on respiration and blood pressure, but the incidence of postoperative nausea and vomiting were higher than deep sedation with propofol. And patient comfort and endoscopic physician satisfaction also need to be improved.
Objective To evaluate the efficacy and safety of endoscopic variceal ligation (EVL) versus endoscopic variceal sclerotherapy (EVS) for acute esophageal variceal bleeding in patients with liver cirrhosis.Methods We searched CBMdisc (1979 to 2006), CNKI (1994 to 2006) and VIP for randomized controlled trials (RCTs) and quasi-RCTs comparing EVL and EVS for acute esophageal variceal bleeding patients with liver cirrhosis. The methodogical quality of included trials was critically assessed and the data were extracted by two reviewers, working independently. The Cochrane Collaboration’s RevMan 4.2.7 software was used for meta-analysis. Results Nine RCTs involving a total of 1371 patients were included: 688 in EVL group and 683 in EVS. The meta-analyses showed a significant reduction for mortality [RR 0.60, 95%CI (0.36, 0.98)], and non-significant reductions in complications, rebleeding and emergency hemostasis in the EVL group compared to the EVS group. EVS was non-significantly better than EVL for the rate of eradication varices and recurrent varices. Conclusions For acute esophageal variceal bleeding in patients with liver cirrhosis, EVL has better effect and fewer complications than EVS. However, because the quality of included RCTs was poor, the strength of our conclusions was limited. Further high-quality RCTs are required.
ObjectiveTo compare postoperatively clinical effect of endoscopic total thyroidectomy via breast approach versus traditional total thyroidectomy via neck in treatment of thyroid papillary carcinoma on postoperative function of parathyroid gland.
MethodsRetrospective study performed on 124 thyroid papillary carcinoma patients who were hospitalized between June 2014 and December 2015 in Department of General Surgery of The First Affiliated Hospital of General Hospital of PLA. All patients underwent total thyroidectomy plus central Ⅵ lymphadenectomy. Endoscopic total thyroidectomy via breast were applied on 48 patients and traditional total thyroidectomy via neck were applied on 76 patients. Serum intact parathyroid hormone (iPTH) and calcium on postoperative day 1 were monitored for all patients. Then comparison of the serum iPTH and calcium between the 2 groups was performed.
ResultsSerum iPTH and calcium for all 124 patients were within the normal range before surgery, and there was no significant difference between the endoscopic total thyroidectomy via breast group and traditional total thyroidectomy via neck group in the serum iPTH and calcium (P > 0.05). On 1 day after surgery, the level of iPTH in endoscopic total thyroidectomy via breast group was lower than that of traditional total thyroidectomy via neck group[(20.8±5.7) pg/mL vs. (28.3±4.9) pg/mL], and ratio of lower iPTH than normal of endoscopic total thyroidectomy via breast group was higher[43.8% (21/48) vs. 22.4% (17/76)], P < 0.05; but there was no significant difference in serum calcium between 2 groups[(2.1±0.3) mmol/L vs. (2.0±0.5) mmol/L], P > 0.05. In addition, the incidence of perioral, chiral and pedal numbness was higher in endoscopic total thyroidectomy via breast group than that of traditional total thyroidectomy via neck group[47.9% (23/48) vs. 27.6% (21/76)], P < 0.05.
ConclusionsComparably, endoscopic total thyroidectomy via breast approach is more prone to lowly postoperative serum iPTH and calcium. Patients are more prone to exhibit clinical symptom such as perioral numbness, chiral and pedal numbness.
Objective To evaluate the clinical effectiveness of ERCP/S+LC and LC+LCBDE in cholecystolithiasis and choledocholithiasis. Methods A fully recursive literature search was conducted in MEDLINE, EMbase, Cochrane Central Register of Controlled Trials in any language. By using a defined search strategy, both the randomized controlled trials (RCTs) and controlled clinical trials on comparing ERCP/ S+LC with LC+LCBDE in cholecystolithiasis and choledocholithiasis were identified. Data were extracted and evaluated by two reviewers independently. The quality of the included trials was evaluated. Meta-analyses were conducted using the Cochrane Collaboration’s RevMan 5.0.2 software. Results Fourteen controlled clinical trials (1 544 patients) were included. The results of meta-analyses showed that: a) There were no significant difference in the stone clearance rate between the two groups (RR=0.96, 95%CI 0.92 to 1.01, P=0.14); b) There were no significant difference in the residual stone rate between the two groups (OR=1.05, 95%CI 0.65 to 1.72, P=0.83); c) There were no significant difference in the complications morbidity between the two groups (OR=1.12, 95%CI 0.85 to 1.55, P=0.48); d) There were no significant difference in the mortality during follow-up visit between the two groups (RD= 0.00, 95%CI –0.03 to 0.03, P=0.84); e) The length of hospital stay in the LC+LCBDE group was shorter than that of the ERCP/S+LC group with significant difference (WMD= 1.78, 95%CI 0.94 to 2.62, Plt;0.000 1); and f) The LC+LCBDE group was superior to the ERCP/S+LC group in the aspects of procedure time and total hospital charges. Conclusion Although there aren’t differences in the effectiveness and safety between the ERCP/S+LC group and the LC+LCBDE group, the latter is superior to the former in procedure time, length of hospital stay and total hospital charges. For the influencing factors of lower quality and astable statistical outcomes of the included studies, this conclusion has to be verified with more strictly designed large scale RCTs.
Objective To summarize the recent minimally invasive approach for cervical spondylotic radiculopathy (CSR). Methods The recent l iterature at home and abroad concerning minimally invasive approach for CSR was reviewed and summarized. Results There were two techniques of minimally invasive approach for CSR at peresent: percutaneous puncture techniques and endoscopic techniques. The degenerate intervertebral disc was resected or nucleolysis by percutaneouspuncture technique if CSR was caused by mild or moderate intervertebral disc herniations. The cervical microendoscopicdiscectomy and foraminotomy was an effective minimally invasive approach which could provide a clear view. The endoscopy techniques were suitable to treat CSR caused by foraminal osteophytes, lateral disc herniations, local l igamentum flavum thickening and spondylotic foraminal stenosis. Conclusion The minimally invasive procedure has the advantages of simple handl ing, minimally invasive and low incidence of compl ications. But the scope of indications is relatively narrow at present.
Radiation proctopathy, which can be categorized as acute and chronic, is defined as the radiation damage to the rectum caused by radiation therapy in patients with pelvic malignancies. Chronic radiation proctopathy can cause complications such as rectal bleeding, which severely affects patients’ quality of life. At present, endoscopic therapy has become the primary method for diagnosis and treatment of bleeding from chronic radiation proctopathy. In October 2019, the American Society for Gastrointestinal Endoscopy (ASGE) published "ASGE guideline on the role of endoscopy for bleeding from chronic radiation". The guideline described the effectiveness and safety of different endoscopic therapies such as argon plasma coagulation, bipolar electrocoagulation, heater probe, radiofrequency ablation, cryoablation, etc. in the treatment of bleeding from chronic radiation. This paper interprets it to provide references for clinicians in the treatment of bleeding from chronic radiation.
Objective To investigate the feasibility and operation effect of endoscopic sentinel lymph node biopsy （SLNB） in breast cancer. Methods The data of 410 breast cancer patients who underwent SLNB （including 107 patients with endoscopy and 303 with open operation） were analyzed in our hospital from January 2009 to March 2012. SLNB was performed by using methylene blue staining or the combination of methylene blue and 99Tcm-sulfur colloid tracing. Results The successful rate of SLN detection with methylene blue and 99Tcm-sulfur colloid tracing was 94.56% （139/147） in open operation group and 94.25% （82/87） in endoscopy group. The successful rate of SLN detection with methylene blue was 88.46% （138/156）in open operation group and 85.00% （17/20） in endoscopy group. The mean of detected SLN number with combined method or methylene blue was 1.90/1.98 in open operation group and 1.91/1.82 in endoscopy group respectively. SLN-positive rate was 22.30% （31/139） and 25.36% （35/138） in open operation group， and 19.51% （16/82） and 23.53% （4/17） in endoscopy group， respectively. The rate of subcutaneous effusion in endoscopy group was higher than that in open operation group （P=0.001）, but other postoperative complications presented no significant difference. Conclusions Endoscopic SLNB can obtain the similar safety and the clinical efficacy with traditional SLNB， but superior cosmetic effect. So it is worthy of clinical application in breast cancer.
