Perforation of the gallbladder with cholecystohepatic communication is a rare cause of liver abscess. Because it is a rare entity, the treatment modality has not been fully established. We report for the first time a patient with an intrahepatic abscess due to gallbladder perforation successfully treated by endoscopic stent placement into the gallbladder who had a poor response to continuous percutaneous drainage.

Duodenal perforations caused by biliary prostheses are not uncommon, and they are potentially life threatening and require immediate treatment. We describe an unusual case of aortic aneurysm and rupture which occurred after retroperitoneal aortoduodenal fistula formation as a rare complication caused by biliary metallic stent-related duodenal perforation. To our knowledge, this is the first report describing a lethal complication of a bleeding, aortoduodenal fistula and caused by biliary metallic stent-induced perforation.

A Killian-Jamieson diverticulum （KID） is an unfamiliar and rare cervical esophageal diverticulum. This diverticulum originates on the anterolateral wall of the proximal cervical esophagus through a muscular gap （the Killian-Jamieson space） below the cricopharyngeal muscle and lateral to the longitudinal muscle of the esophagus. To date, only surgical treatment has been recommended for a symptomatic KJD due to its close proximity to the recurrent laryngeal nerve and the concern of possible nerve injury. Recently, traditional open surgery for a symptomatic KJD is being challenged by the development of new endoscopic techniques and devices. We present here a case of a symptomatic KID that was successfully treated with the flexible endoscopic diverticulotomy using two new devices. An isolated-tip needle-knife papillotome （Iso-Tome） was used for the dissection of the tissue bridge of the diverticulum. And a flexible overtube with a modified distal end （a fitted overtube） was used for adequate visualization of the tissue bridge of the diverticulum and protection of the surrounding tissue during dissection of the tissue bridge. Our successful experience suggests that the flexible endoscopic diverticulotomy with the use of appropriate endoscopicdevices can be a safe and effective method for the treatment of a symptomatic KJD.

AIM： To investigate the relationship between postendoscopic resection （ER） scars on magnifying endoscopy （ME） and the pathological diagnosis in order to validate the clinical significance of ME. METHODS： From January, 2007 to June, 2008, 124 patients with 129 post-ER scar lesions were enrolled. Mucosal pit patterns on ME were compared with conventional endoscopy （CE） findings and histological results obtained from targeted biopsies. RESULTS： CE findings showed nodular scars （53/129）, erythematous scars （85/129）, and ulcerative scars （4/129）. The post-ER scars were classified into four pit patterns of sulci and ridges on ME：（ Ⅰ ） 47 round; （Ⅱ） 54 short rod or tubular; （Ⅲ） 19 branched or gyrus-like;and （Ⅳ） 9 destroyed pits. Sensitivity and specificity were 88.9% and 62.5%, respectively, by the presence of nodularity on CE. Erythematous lesions were high sensitivity （100%）, but specificity was as low as 36.7%. The range of the positive predictive va ue （PPV） on CE was as low as 10.6%-25%. Nine type N pit patterns were diagnosed as tumor lesions, and 120 cases of type Ⅰ-Ⅲ pit patterns revealed non-neoplastic lesions. Thus, the sensitivity, specificity, and the PPV of ME were 100%. CONCLUSION： ME findings can detect the presence of tumor in post-ER scar lesions, and make evident the biopsy target site in short-term follow-up. Further large-scale and long-term studies are needed to determine whether ME can replace endoscopic biopsy.

Adenomyoma is a term generally applied to nodular lesions showing proliferation of both epithelial and smooth muscle components. Despite its benign nature,ampullary adenomyoma is usually presented as biliary obstruction. Most cases are misdiagnosed as carcinoma or adenoma by preoperative endoscopic or radiologic procedure. Therefore,it is frequently treated with extensive surgery. To our knowledge,this is the first reported case in English literature of adenomyoma located in the peripancreatic orifice resulting in intermittent pancreatic duct obstruction and recurrent pancreatitis diagnosed by the endoscopic piecemeal resection.

Rice is the staple food for more than half of the world’s population,and the demand for rice is expected to increase by 28%by 2050(Jiang et al.,2017).However,rice production is one of the largest anthropogenic sources of the potent greenhouse gas methane(CH4),accounting for 22%of total agricultural CH4 emissions(Qian et al.,2023).Therefore,to achieve sustainable intensification of rice cultivation,it is necessary to increase yields while reducing CH4 *** management techniques to reduce CH4 emissions while maintaining high yields have been studied extensively over the past few decades,but crop breeding to reduce CH4 emissions without compromising yields has received less attention(Kwon et al.,2023).
