RESUMO
Objective:To compare the safety and effectiveness of endoscopic full-thickness resection (EFR) and cap-assisted endoscopic full-thickness resection (EFR-C) in the treatment of small gastric stromal tumors (≤1.5 cm) in the elderly (≥60 years old).Methods:Data of elderly patients with small gastric stromal tumors who received EFR (41 cases) or EFR-C (25 cases) at Nanjing Drum Tower Hospital from May 2012 to August 2020 were analyzed retrospectively. The clinicopathological characteristics, the procedures, intraoperative and postoperative complications, postoperative efficacy and economic benefits were compared between the two groups.Results:The R0 resection rates of the EFR group and the EFR-C group were 95.1% (39/41) and 100% (25/25), respectively. The operation time [45.0 (32.5, 66.5) min VS 30.0 (20.0, 42.5) min, U=259.500, P=0.001] and resection time [30.0 (20.0, 50.5) min VS 9.0 (6.5, 16.5) min, U=127.000, P<0.001] of the EFR group were significantly longer than those of the EFR-C group. The rate of hot clamp use in the EFR group was higher than that in the EFR-C group [75.6% (31/41) VS 12.0% (3/25), χ ２=25.159, P<0.001]. The postoperative white blood cell count [8.3 (6.6,10.4)×10 9/L VS 6.3 (5.0,7.7) ×10 9/L, U=271.000, P=0.001] and postoperative neutrophil percentage (77.6%±8.8% VS 73.0%±6.8%, t=2.256, P=0.027) in the EFR group were higher than those in the EFR-C group. The postoperative antibiotic day in the EFR group was longer than that in the EFR-C group (2.8±2.0 days VS 1.0±2.0 days, t=3.625, P=0.001). The hospitalization costs in the EFR group were significantly higher than those in the EFR-C group (20 595.0±3 653.3 yuan VS 13 209.0±4 458.9 yuan, t=7.323, P<0.001). There was no recurrence or metastasis during the follow-up period. Conclusion:EFR and EFR-C are safe and effective for the treatment of small gastric stromal tumors in the elderly. Compared with EFR, EFR-C needs shorter operation time and lower medical costs, yields less postoperative inflammation, and is more suitable for the treatment of small gastric stromal tumors in the elderly.
RESUMO
Objective:To compare the efficacy and safety of cap-assisted endoscopic sclerotherapy (CAES) and procedure for prolapse and hemorrhoids (PPH) for internal hemorrhoids.Methods:This study was a prospective double-blind controlled clinical one. A total of 80 patients with internal hemorrhoids who visited Baoding No.1 Central Hospital from March 2018 to March 2020 and met the inclusion and did not meet exclusion criteria, were randomly divided into CAES group ( n=40) and PPH group ( n=40) by random number table method, and received corresponding treatment respectively. The perioperative indices of the two groups were compared, including intraoperative blood loss, operation time, visual analogue scale (VAS) score at 24 and 48 hours after operation, length of hospital stay, treatment costs, time to return to normal life, and curative rates. The complications within 3 months after operation and the 1-year recurrence after operation were also compared between the two groups. Results:The operation was successfully completed in all patients. The intraoperative blood loss (0.54±0.15 mL VS 7.32±2.17 mL) and treatment cost (6 249.53±435.67 yuan VS 7 832.96±526.74 yuan) in CAES group were significantly lower than those in PPH group ( t=19.714, P<0.05; t=14.650, P<0.05). The length of hospital stay (3.53±0.94 d VS 5.18±1.36 d) and time to return to normal life (5.26±1.28 d VS 7.17±2.09 d) in CAES group were significantly lower than those in PPH group ( t=6.312, P<0.05; t=4.929, P<0.05). There was no significant difference in operation time between the two groups ( t=0.977, P>0.05). The VAS scores at 24 h (2.64±0.70 points VS 3.59±0.93 points) and 48 h (1.28±0.31 points VS 2.16±0.57 points) after operation in CAES group were significantly lower than those in PPH group ( t=5.162, P<0.05; t=8.578, P<0.05). There was no significant difference in the curative rate [90.0% (36/40) VS 97.5% (39/40)] between CAES group and PPH group ( χ2=0.853, P=0.356). During the follow-up period within 3 months after the operation, the incidence of urinary retention [0.0% (0/40) VS 15.0% (6/40)] and pain [2.5% (1/40) VS 22.5% (9/40)] in CAES group was significantly lower than those in PPH group ( χ2=4.504, P<0.05; χ2=7.314, P<0.05). No other complications occurred in the 80 patients. After 1 year of follow-up, the recurrence rate of CAES group was 7.5% (3/40), which was not statistically different from that in PPH group [5.0% (2/40), χ2=0.180, P>0.05]. Conclusion:As a new minimally invasive technique for the treatment of internal hemorrhoids, CAES has similar curative rate and 1-year recurrence rate to PPH. Compared with PPH, CAES shows the advantages of less trauma, less pain, faster recovery and lower cost.
RESUMO
BACKGROUND/AIMS: Food bolus impaction is the most common form of esophageal foreign body impaction observed in adults. Clinical guidelines recommend using the push technique or retrieval methods in such cases. The push technique can cause injuries in certain clinical situations. Notably, conventional retrieval methods are time and effort consuming. Cap-assisted endoscopic extraction of an impacted food bolus is an easy and effective technique; however, more data are needed for its validation. This study compared the capassisted extraction technique with conventional methods. METHODS: This prospective observational multicenter study compared the success and en bloc removal rates, total procedure time, and adverse events in both techniques.. RESULTS: The study included 303 patients who underwent food bolus extraction. The push technique was used in 87 patients (28.7%) and a retrieval procedure in 216 patients (71.3%). Cap-assisted extraction was performed in 106 patients and retrieval using conventional methods in 110 patients. The cap-assisted technique was associated with a higher rate of en bloc removal (80.2% vs. 15%, p<0.01), shorter procedure time (6.9±3.5 min vs. 15.7±4.1 min, p<0.001), and fewer adverse events (0/106 vs. 9/110, p<0.001). CONCLUSIONS: Cap-assisted extraction showed no adverse events, higher efficacy, and a shorter procedure time compared with conventional retrieval procedures.

Endoscopic retrograde cholangiopancreatography (ERCP) is an advanced therapeutic procedure to manage choledocholithiasis and pancreatobiliary malignancy. On occasion, ERCP failure is encountered due to difficulties in cannulation. We assessed the safety and feasibility of cap-assisted ERCP via analyzing cases in which cannulation was complicated by periampullary diverticulum. Between November 2013 and March 2014, ERCP procedures were performed in 346 patients in our tertiary medical center. Among the 73 patients who had a periampullary diverticulum, conventional ERCP failed in 5 patients due to hidden papilla (n=3) or use of tangential approach (n=2). As a rescue method, needle knife fistulotomy and selective biliary cannulation using cap-fitted forward-viewing endoscopy were successfully used in 4 patients without major complications. Based on our experience, cap-fitted forward-viewing endoscopy was relatively easy to measure the exact position of papilla and to perform biliary cannulation properly. Therefore, we recommend using cap-assisted ERCP by forward-viewing endoscopy as a useful and safe alternative to manage patients in whom cannulation is complicated by periampullary diverticulum.

Objective To evaluate the methodology, feasibility, safety and efficacy of cap-assisted endoscopic sclerotherapy(CAES)for hemorrhoids. Methods Patients with grade Ⅰ to Ⅲ internal hemorrhoids underwent CAES from September 2014 to May 2016. According to the methodology of CAES, reasons for blooding were identified and polypectomy and excision of anal papilla fibroma was performed. Efficacy,intraoperative and postoperative complications and patient satisfaction were evaluated during and after CAES. The follow-up was more than three months. Results A total of 48 patients with gradeⅠ toⅢinternal hemorrhoids underwent CAES,including 25(52.1%)patients with grade Ⅰ,21(43.8%)patients with grade Ⅱ,and 2(4.2%)grade Ⅲ. During the whole procedure of CAES, colon and terminal ileum examination was performed in 48(100.0%)patients, polypectomy was performed in 14(29.2%)patients, excision of anal papilla fibroma was performed in 1(2.1%)patient, excision of external hemorrhoids was performed in 1(2.1%)patient,biopsy for the polyps on dentate line was performed in 2(4.2%)patients, and sclerotherapy for rectal mucosal prolapse was performed in 2(4.2%)patients. No bleeding was observed during and after CAES. Infection occurred in one(2.1%)patient, who recovered with a one-week anti-infective therapy. One(2.1%)patient claimed mild tenesmus within four days after CAES.No complications were observed within the three-month follow-up. All patients(100.0%)were satisfied with this novel procedure. Conclusion CAES, as a novel endoscopic sclerotherapy, is a safe and effective endoscopic therapy with high patient satisfaction for internal hemorrhoids.
RESUMO
A 73-year-old woman presented with intermittent abdominal pain and weight loss of 15 kg for 2 years. Colonoscopy revealed an erythematous polypoid tumor with a long and wide stalk in the cecum, but with air inflation, it abruptly went away through the ileocecal valve (ICV). An abdominal computed tomography showed a well-demarcated pedunculated subepithelial mass of 2.6x2.7 cm size with fat attenuation in the terminal ileum. It was an intussusceptum of the ileal lipoma through the ICV. This ileal lipoma was causing her symptoms because repeated ileocolic intussusceptions resulted in intermittent intestinal obstructions. In order to avoid surgical sequelae of ileal resection, snare polypectomy using cap-assisted colonoscopy technique was performed within the ileum without complications. The histopathology report confirmed it as a subepithelial lipoma. After endoscopic resection of the ileal lipoma, the patient has been free of symptoms and was restored to the original weight.

BACKGROUND/AIMS: Endoscopic retrograde cholangiopancreatography (ERCP) is a difficult procedure to perform on patients who have undergone a Billroth II gastrectomy, Whipple's operation or Roux-en-Y gastrobypass surgery. Our study was designed to evaluate the clinical usefulness of cap-assisted ERCP for beginner endoscopists in cases of surgically altered anatomy. METHODS: From April 2008 to March 2010, 16 patients with biliary diseases and who had previously undergone abdominal surgery such as Billroth II gastrectomy or Roux-en-Y operation were analyzed. A single endoscopist performed all the procedures using a cap-assisted gastroscope, after ERCP training. RESULTS: Cap-assisted ERCP was attempted in 24 sessions of 16 patients. Afferent loop intubation and selective bile duct cannulation was successfully achieved in 19 sessions (79.1%). Among the patients who had undergone a Billroth II gastrectomy, 19 out of 20 sessions were successfully conducted. Only 4 patients who had undergone a previous Roux-en-Y operation failed afferent loop intubation. Duodenal free wall perforation developed in one case. There were no cases of mortality. CONCLUSIONS: Therapeutic cap-assisted ERCP was useful in patients who had previously undergone a Billroth II gastrectomy and this may be helpful for inexperienced endoscopists.
