RESUMO
BACKGROUND/AIMS: Treating Helicobacter pylori infection in young people is effective for preventing gastric cancer. This study compares the efficacy of triple therapies in adolescents and young adults in Japan. METHODS: This multicenter, randomized trial was conducted between February 2012 and March 2015. Infected participants were stratified into adolescents (13-19 years) and young adults (20-39 years). They were randomly assigned to a clarithromycin based (PAC) or metronidazole based (PAM) triple therapy for 1 week. RESULTS: Overall, 137 and 169 participants received the PAC and PAM treatments, respectively. In adolescents, the H. pylori eradication rates were 60.5% and 63.4% for PAC, and 98.3% and 100% for PAM in the intention-to-treat (ITT) and per-protocol (PP) analyses, respectively. In young adults, the eradication rates were 67.0% and 66.7% for PAC, and 95.5% and 96.3% for PAM in ITT and PP analyses, respectively. The eradication rate of PAM was significantly higher than that of PAC in both strata. No severe adverse events were observed. CONCLUSION: In Japan, PAM may be selected as a first-line treatment for young people with H. pylori if antibiotic susceptibility tests cannot be performed.

Transvaginal organ prolapse, such as small bowel evisceration, is a rare complication after radical cystectomy (RC) in female patients with invasive bladder cancer, However, it often requires emergency surgical repair. Here, we describe our experience with such a case and a review of similar previously reported cases, along with evaluation of the risk factors. We also propose a vaginal reconstruction technique to prevent this complication during robot-assisted laparoscopic radical cystectomy (RARC). A total of 178 patients who underwent laparoscopic radical cystectomy (LRC) or RARC were enrolled, 34 of whom (19%) were female. One of the 34 female patients had transvaginal small bowel evisceration after RARC. We evaluated our case and six such previously reported cases, to determine vaginal reconstruction techniques during RARC to prevent this complication postoperatively. Median age of these cases was 73 (51-80) years, and all patients were postmenopausal. The median time to small bowel evisceration was 14 (6-120) weeks postoperatively. In addition, we changed the methods of the vaginal reconstruction technique during RARC from the conventional side-to-side closure technique to the improved caudal-to-cephalad closure technique. Since implementing this change, we have not experienced any cases of vaginal vault dehiscence or organ prolapse. Transvaginal small bowel evisceration after RC can easily become severe. Therefore, all possible preventive measures should be taken during RARC. We believe that our vaginal reconstruction techniques might reduce the risk of developing this complication.

Introduction: We performed autologous rectus abdominis fascia sling surgery using Advantage™ following an unsuccessful synthetic midurethral sling. Case presentation: At the age of 76 years, the patient experienced stress urinary incontinence recurrence. A 1-h pad test resulted in 259 g of leakage. A pressure flow study verified urine leakage while coughing and straining without detrusor overactivity. Abdominal leak point pressure was 10 cmH2O. Autologous rectus abdominis fascia sling surgery was performed using Advantage™. One month postoperatively, a 1-h pad test resulted in 0 g of leakage. Conclusion: We believe that this method will allow the fascia sling procedure to be performed reliably even if one is unfamiliar with conventional autologous rectus abdominis fascia sling surgery.
RESUMO
BACKGROUND: The cancer risk for each length of Barrett's esophagus (BE) in Japanese is unknown. This nationwide, multi-institutional study aims to clarify the cancer risk by length of BE in the general Japanese population. METHODS: Consecutive subjects who underwent upper endoscopic screening at 17 centers between 2013 and 2017 and had at least one follow-up endoscopy by December 2022 were included. The presence/absence of BE and, if present, its length were retrospectively assessed using the retrieved endoscopic images recorded at baseline. Information on the subsequent occurrence of esophageal adenocarcinoma and other upper gastrointestinal cancers was also collected. Cancer incidence was calculated and expressed as %/year. RESULTS: A total of 33,478 subjects were enrolled, and 17,884 (53.4%), 10,641 (31.8%), 4889 (14.6%), and 64 (0.2%) were diagnosed as absent BE, BE < 1 cm, 1-3 cm, and ≥ 3 cm, respectively. During a median follow-up of 80 months, 11 cases of esophageal adenocarcinoma developed. The annual incidence of esophageal adenocarcinoma is 0%/year for absent BE, 0.0032 (0.00066-0.013)%/year for BE < 1 cm, 0.026 (0.011-0.054)%/year for 1-3 cm, and 0.58 (0.042-2.11)%/year for ≥ 3 cm, respectively. Meanwhile, the incidence of esophageal squamous cell carcinoma and gastric cancer were 0.039 (0.031-0.049)%/year and 0.16 (0.14-0.18)%/year, respectively. CONCLUSIONS: By enrolling a large number of subjects with long-term follow-up, this study demonstrated that the risk of cancer increased steadily with increasing length of BE in the Japanese population. Therefore, it is important to consider the length of BE when determining the management strategy for BE.
RESUMO
The ClearPetra (Well Lead Medical, Guangzhou, China) has recently entered the market, enabling continuous stone fragmentation and removal while maintaining a continuous perfusion field of view. The efficacy and safety of the ClearPetra renal access sheath (RAS) in percutaneous nephrolithotomy (PCNL) and endoscopic combined intrarenal surgery (ECIRS) have been reported. However, no reports have described the use of the ClearPetra ureteral access sheath (UAS). Here, we report a case of successful ureteroscopic lithotripsy (URSL) for a giant ureteral stone by effectively utilizing the ClearPetra UAS.
RESUMO
A man in his fifties had a medical checkup. Mucosal papillomatosis in his oral cavity and palmoplantar keratosis were observed. Esophagogastroduodenoscopy revealed multiple polypoid lesions both in the esophagus and stomach. In addition, colonoscopy showed schwannoma in the rectum. He underwent an operation for adenomatous goiter. At first his typical esophageal multiple polypoid lesion was a diagnostic cue to Cowden disease (CD). Other clinical findings convinced us that he was suffering from CD. He was, then, diagnosed as CD according to the criteria of International Cowden Consortium although he had no family medical history suspicious of CD. Interestingly, genetic testing revealed that the patient had a germline mutation in exon5 of PTEN on chromosome 10. It was a point mutation of C to T transition at codon130, resulting in nonsense mutation (CGAâTGA). A close follow-up, especially cancer surveillance, is necessary for him since CD is associated with a high risk of developing malignant disease. It is noted that the typical esophageal features can be a diagnostic cue to CD, as shown in the present case.

BACKGROUND/AIMS: It is important to appropriately manage patients with procedure-related artificial mucosal ulcers or procedure-related complications. Many endoscopic closure techniques have been reported; however, they often require the use of special devices. We developed a single-channel endoscopic closure technique (SCCT) that can be performed with conventional devices. In the present study, we describe the technique and evaluate its efficacy. METHODS: Twenty-five consecutive patients who underwent endoscopic treatment and whose artificial ulcer was closed using the SCCT were enrolled in this study. The technical success rate, number of clips for closure, procedure time, complication rate on the day of the procedure, clinical success rates on days 1 and 5, and incidence of severe stenosis of the gastrointestinal (GI) tract at 2 months after the procedure were evaluated. RESULTS: The median ulcer diameter was 20 mm. The tumor locations were the stomach (n = 19), jejunum (n = 1), and colon (n = 5). The technical success rate was 100% (25/25), and the rate of incomplete closure was 0% (0/25). Eight clips were needed on average. The median procedure time was 18 min (range 5-49 min). The complication rate was 0% (25/25). The clinical success rates on days 1 and 5 were 100% (19/19) and 100% (9/9), respectively. No patients presented stenosis as a late complication at 2 months after the procedure (0/25). CONCLUSION: The SCCT could be applied in the treatment of artificial ulcers in several parts of the GI tract with a high clinical success rate and no complications. The SCCT appears to be a good option for closing artificial mucosal ulcers.
RESUMO
BACKGROUND: Impairment of gastric emptying is well recognized in patients with diabetes mellitus (DM), especially long-standing insulin-dependent diabetes mellitus (IDDM). The aim of this study was to evaluate the cause of delayed gastric emptying in DM patients. METHODS: In 16 controls, 16 non-insulin-dependent diabetes mellitus (NIDDM) patients and 23 IDDM patients, gastric emptying was studied using the (13)C octanoic acid breath test. Breath samples were taken before a test meal labeled with 100 mg of (13)C octanoic acid, and at 15-min intervals over a 300-min period postprandially. RESULTS: In all DM patients, the gastric emptying coefficient was lower than that in the controls (P < 0.05), and lag time and half-emptying time were significantly longer (P < 0.05). Both NIDDM and IDDM patients showed delayed (13)CO(2) excretion compared with the controls, but IDDM patients showed more delayed gastric emptying than NIDDM patients (P < 0.05). There were no significant differences in sex, HbA1c level, or the rate of neuropathy between the two groups. CONCLUSIONS: IDDM patients showed delayed gastric emptying compared with NIDDM patients, and the (13)C octanoic acid breath test is useful for evaluating DM patients with delayed gastric emptying.

This report describes an extremely rare adult case of an omphalomesenteric cyst resected by laparoscopic-assisted surgery. A 29-years-old Japanese man was referred and admitted to Kyushu University Hospital because of an abdominal mass and an elevated serum CEA (carcinoembryonic antigen) level (21.3 ng/mL) in August 2001. Abdominal CT and US demonstrated a cystic mass with septum and calcification. Laparoscopy showed a large mass to be attached to his abdominal wall, measuring 110 mm x 70 mm x 50 mm and filled with mucus. The mass was resected by laparoscopic-assisted surgery. The histological findings of its wall showed fibromuscular tissue, adipose tissue, calcification, and an intestinal structure. It was finally diagnosed to be an omphalomesenteric cyst.

We report a novel germline mutation of the PTEN gene in a Japanese family with Cowden disease. A 46-year-old Japanese man and his mother were diagnosed as having Cowden disease. Their physical examinations revealed multiple facial trichilemmoma, oral mucosal papillomatosis, palmoplantar keratosis, and gastrointestinal polyposis. The single-strand conformation polymorphism (SSCP) analysis showed an abnormal band on exon 7 of their PTEN gene. Direct sequence analysis of exon 7 detected a TAAA insertion to codon 221, producing a stop codon (c.663ins TAAA).
