ObjectiveTo systematically review the effectiveness and safety of laparoendoscopic single-site surgery (LESS) for varicocele. MethodsSuch databases as The Cochrane Library, MEDLINE, EMbase, CBM, CNKI, and WanFang Data were electronically searched for studies about LESS and traditional laparoscopy for varicocele till March 1st, 2013. According to the inclusion and exclusion criteria, literature was screened, data were extracted, and the methodological quality of included studies was also assessed. Then, meta-analysis was performed using RevMan 5.1 software. ResultsSeven RCTs involving 452 cases were included. The results of meta-analysis showed that, there was no significant difference between LESS and traditional laparoscopy for varicocele on post-operational complications (RR=0.57, 95%CI 0.26 to 1.27, P=0.17), duration of hospital stay (MD=-0.30, 95%CI-0.87 to 0.26, P=0.30), improvement of semen parameters, and blood loss. However, LESS had longer duration of operation (MD=11.26, 95%CI 3.62 to 18.90, P=0.004). ConclusionThe effectiveness and safety of LESS and traditional laparoscopy for varicocele are similar, and LESS could achieve more beautiful and natural effects which has longer surgery time on account of non-proficiency in surgery and equipment. Due to the limited quantity and quality of the included studies, the above conclusion requires to be proved by more high quality randomized controlled trials.
Objective To investigate therapeutic effect of endoscopic sphincterotomy with small incision (SES) combined with endoscopic papillary balloon dilation (EPBD) in treatment of larger common bile duct stones. Methods The clinical data of 80 patients with common bile duct stones treated in our hospital from February 2014 to October 2015 were retrospectively analyzed. These patients were divided into endoscopic sphincterotomy (EST) group (n = 40) and SES+EPBD group (n = 40) according to the therapeutic methods. The diameter of common bile duct stone was 10–20 mm. The operation status, recurrence rate and residual rate of common bile duct stone, and complications rate within 3 months after operation were compared between these two groups. Results The age and gender had no significant differences between these two groups (P>0.05). The operation time was shorter (P<0.05) and the intraoperative bleeding was less (P<0.05) in the SES+EPBD group as compared with the EST group. There were no significant differences in the hospital stay and recovery time of gastrointestinal function between these two groups (P>0.05). The levels of ALT, AST, DBIL, and TBIL in these two groups before treatment had no significant differences (P>0.05); after treatment, the above indicators of liver function in the SES+EPBD group were significantly lower than those in the EST group (P<0.05), and which were significantly decreased more in the same group (P<0.05). The residual stone, stone recurrence, and complications such as acute pancreatitis, acute cholangitis, bile leakage and postoperative hemorrhage were not found in the SES+EPBD group, the rates of these indicators in the SES+EPBD group were significantly lower than those in the EST group (P<0.05). Conclusion SES combined with EPBD has a good therapeutic effect on larger common bile duct stones (diameter of common bile duct stone is 10–20 mm) and recurrence rate is low.
ObjectiveTo evaluate the short-term effectiveness of percutaneous endoscopic lumbar discectomy (PELD) in treatment of buttock pain associated with lumbar disc herniation.MethodsBetween June 2015 and May 2016, 36 patients with buttock pain associated with lumbar disc herniation were treated with PELD. Of 36 cases, 26 were male and 10 were female, aged from 18 to 76 years (mean, 35.6 years). The disease duration ranged from 3 months to 10 years (mean, 14 months). The location of the pain was buttock in 2 cases, buttock and thigh in 6 cases, buttock and the ipsilateral lower extremity in 28 cases. Thirty-four patients had single-level lumbar disc herniation, and the involved segments were L4, 5 in 15 cases and L5, S1 in 19 cases; 2 cases had lumbar disc herniation at both L4, 5 and L5, S1. The preoperative visual analogue scale (VAS) score of buttock pain was 6.1±1.3. VAS score was used to evaluate the degree of buttock pain at 1 month, 3 months, 6 months, and last follow-up postoperatively. The clinical outcome was assessed by the modified MacNab criteria at last follow-up.ResultsAll patients were successfully operated and the operation time was 27-91 minutes (mean, 51 minutes). There was no nerve root injury, dural tear, hematoma formation, or other serious complications. The hospitalization time was 3-8 days (mean, 5.3 days). All incisions healed well and no infection occurred. Patients were followed up 12-24 months (median, 16 months). MRI examination results showed that the dural sac and nerve root compression were sufficiently relieved at 3 months after operation. Patients obtained pain relief after operation. The postoperative VAS scores of buttock pain at 1 month, 3 months, 6 months, and last follow-up were 1.1±0.6, 0.9±0.3, 1.0±0.3, and 0.9±0.4 respectively, showing significant differences when compared with preoperative VAS scores (P<0.05); there was no significant difference in VAS score between the different time points after operation (P>0.05). At last follow-up, according to the modifed MacNab criteria, the results were excellent in 27 cases, good in 9 cases, and fair in 2 cases, and the excellent and good rate was 94.4%.ConclusionPELD can achieve satisfactory short-term results in the treatment of buttock pain associated with lumbar disc herniation and it is a safe and effective minimally invasive surgical technique.
ObjectiveTo summarize the current common clinical laparoscopic gastrointestinal tumor surgical localization methods, and to provide reference for clinicians to choose reasonable localization methods. MethodThe domestic and foreign literatures related to laparoscopic gastrointestinal tumor surgical localization methods were searched and reviewed. ResultsThe common localization methods for laparoscopic gastrointestinal tumor surgery were imaging localization, preoperative endoscopic localization, intraoperative endoscopic localization and intraoperative fluorescence localization, among which abdominal enhanced CT and endoscopic-related localization methods were the most commonly used localization methods in clinical practice at present. ConclusionA variety of methods are available for surgeons to choose from, and the precise localization of tumors is better facilitated by combining multiple methods.

MethodLiteratures on AI in the field of gastrointestinal tumors in recent years were reviewed and summarized.ResultsAI had developed rapidly in the medical field. The gastrointestinal endoscopy, imaging examination, and pathological diagnosis assisted by AI technology could assist doctors to make more accurate diagnosis opinions, and make the diagnosis and treatment of gastrointestinal tumors develop towards a more accurate and efficient direction. However, the application of AI in the medical field had just begun, and it still needed to be popularized for a long time.ConclusionThe gastrointestinal endoscopy system, imaging examination system, and pathological diagnosis assisted by AI technology all show high specificity and sensitivity, which obviously reflects its high efficiency and accuracy.
ObjectiveTo evaluate the clinical experiences and treatment effectiveness of chronic venous insufficiency with venous ulcer in lower limb. MethodsSeventy-eight patients (88 limbs) suffering lower limb chronic venous insufficiency with venous ulcer from May 2004 to April 2011 in this hospital were analyzed retrospectively. All the patients had undergone high ligation for great saphenous vein plus endovenous laser treatment plus subfascial endoscopic perforator vein surgery (SEPS). ResultsPostoperative complications included 3 cases of subfascial haematoma; 2 cases of pneumohypoderma; 3 cases of numbness in anterior tibial and ankle areas. All the ulcers healed between 4 to 6 weeks. Follow up period was between 6 months to 5 years. There was only one recurrence due to residual varicose from ankle area. The mean operation time was 20 min (15－30 min) in SEPS, the average blood loss was 2 ml (1－5 ml), and the mean duration of postoperative hospitalization was 5 d (2－8 d). ConclusionsSEPS is a first treatment choice for CVI with venous ulcer. It has less invasiveness, lower chances for bleeding, shorter operation time, quicker recovery, and fewer complications.
Objective To analyze the clinical characteristics of patients treated with esophagectomy following endoscopic submucosal dissection (ESD) for early stage esophageal cancer or precancerosis and the reasons for esophagectomy. Methods We retrospectively analyzed the clinical data of 57 patients who were treated with esophagectomy following ESD in West China Hospital and Shanxian Hygeia Hospital from January 2012 through October 2016. There were 42 males and 15 females at age of 65.4 (52–77) years. There were 15 patients of upper thoracic lesions, the middle thoracic lesions in 34 patients, and the lower thoracic lesions in 8 patients. Results The reasons for esophagectomy included 3 patients with residual tumor, 8 patients with local recurrence, 37 patients with esophageal stricture, and 9 patients with dysphagia, although the diameter was larger than 1.0 cm. The pathology after esophagectomy revealed that tumor was found in 16 patients, including 3 patients with residual tumor and 8 with recurrent tumor confirmed before esophagectomy, and 5 patients with new-found recurrent tumor. Conclusion In the treatment of early stage esophageal cancer or precancerosis, the major reasons for esophagectomy following ESD include esophageal stricture, abnormal esophageal dynamics, local residual or recurrence.
Objective To evaluate the feasibility and safety of percutaneous endoscopic technique in the treatment of intraspinal cement leakage after percutaneous vertebroplasty (PVP). Methods Between May 2014 and March 2016, 5 patients with lower limb pain and spinal cord injury caused by intraspinal cement leakage after PVP, were treated with percutaneous endoscopic spinal decompression. Of 5 cases, 3 were male and 2 were female, aged from 65 to 83 years (mean, 74.4 years). The course of disease was 10-30 days (mean, 16.2 days). Imageological examinations confirmed the levels of cement leakage at T 12, L 1 in 3 cases, and at L 1, 2 in 2 cases; bilateral sides were involved in 1 case and unilateral side in 4 cases. Two patients had lower limb pain, whose visual analogue scale (VAS) were 8 and 7; 3 patients had lower extremities weakness, whose Japanese Orthopedic Association (JOA) 29 scores were 18, 20, and 19. According to American Spinal Injury Association (ASIA) impairment scale, neural function was rated as grade E in 2 cases and grade D in 3 cases. Results The operation time was 55-119 minutes (mean, 85.6 minutes), and the blood loss was 30-80 mL (mean, 48 mL). CT scan and three-dimensional (3D) reconstruction at 1 day after operation showed that cement leakage was removed in all patients. Five cases were followed up 6-21 months (mean, 12 months). In 2 patients with lower limb pain, and VAS score was significantly decreased to 2 at last follow-up. In 3 patients with lower extremities weakness, the muscle strength was improved progressively, and the JOA29 scores at last follow-up were 21, 23, and 22. Conclusion Percutaneous endoscopic technique for intraspinal cement leakage after PVP is safe, effective, and feasible.
ObjectiveTo systematically evaluate the reliability and stability of transoral endoscopic thyroidectomy vestibular approach (TOETVA) and conventional open thyroidectomy (COT) in the treatment of differentiated thyroid cancer.MethodsThe clinical studies of TOETVA and COT in the treatment of differentiated thyroid cancer were retrieved from major databases including PubMed, Embase, Cochrane Library, Wanfang, and CNKI by computer. The search date ended on March 1, 2020. Two investigators screened the literatures strictly and extracted the data following the pre-defined inclusion and exclusion criteria, and then used RevMan 5.3 software for meta-analysis.ResultsA total of 7 studies including 1 465 patients were included in this meta-analysis. The results showed: compared with the COT group, the operation time of the TOETVA group was longer [WMD=35.18, P=0.000 1], and the number of lymph node dissections in the central area was larger [WMD=1.42, P=0.000 5]. But the intraoperative blood loss [WMD=–5.32, P=0.39], the length of hospital stay after operation [WMD=0.05, P=0.94], the incidences of transient recurrent laryngeal nerve palsy [OR=0.81, P=0.43], transient hypocalcemia [OR=0.55, P=0.35], permanent hypocalcemia [OR=0.39, P=0.22], permanent recurrent laryngeal nerve palsy [OR=1.34, P=0.73], and hematoma [OR=1.29, P=0.69] were not statistically significant between the two groups.ConclusionsTOETVA has a higher stability. Although the COT has a shorter operation time, the former has a higher central lymph node dissection rate, and there is no scar on the neck after surgery and no significant difference in the incidence of postoperative complications.
