RESUMEN

BACKGROUND The spring-and-loop with clip (S-O clip) consists of a spring and a nylon loop located on one side of the claws of the clip, and is used in gastric endoscopic submucosal dissection (ESD) to allow countertraction. This retrospective study included 290 patients with early gastric neoplasms (eGNs) and aimed to compare postoperative outcomes of ESD with and without the use of the S-O clip. MATERIAL AND METHODS We retrospectively reviewed the data of 347 patients with eGN who underwent ESD, with or without an S-O clip, at our institution between April 1, 2017 and March 31, 2023. Overall, 290 patients were analyzed after excluding ineligible participants. The control group (n=149; adenoma: 1, carcinoma: 148) underwent ESD without an S-O clip between April 2017 and March 2020, while the S-O group (n=141; adenoma: 4, carcinoma: 137) used the clip between April 2020 and March 2023. Primary outcomes included procedure time, en bloc resection rate, and complete resection rate. Subgroup analysis for examined procedure time concerning endoscopist expertise, submucosal fibrosis, and neoplasm locations. RESULTS The S-O group had a shorter procedure time (44.4±23.9 vs 61.1±40.9 min, P<0.001) and a higher complete resection rate (97.9% vs 92.6%, P<0.05) than the control group. Subgroup analysis revealed that the S-O clip significantly reduced procedure time for trainees compared to the control group (40.8±18.3 vs 61.1±35.6 min, P<0.05). CONCLUSIONS The scheduled use of S-O clips in gastric ESD is effective in improving procedural time and complete resection rates, benefiting endoscopists across all experience levels.

RESUMEN

BACKGROUND Parkinson's disease (PD) is a neurodegenerative disorder that often requires long-term management of motor symptoms. Continuous infusion of levodopa-carbidopa intestinal gel (LCIG) has shown promising results in alleviating motor fluctuations and improving quality of life. This study aimed to evaluate the efficacy and safety of transgastric jejunostomy (PEG-J) as a delivery method for LCIG in a cohort of 43 PD patients. MATERIAL AND METHODS Forty-three PD patients who were candidates for LCIG therapy underwent transgastric jejunostomy to facilitate continuous infusion of LCIG. The primary outcomes assessed were motor symptom improvement, reduction in motor fluctuations, and medication-related adverse events. Secondary outcomes included changes in quality of life, dyskinesia severity, and healthcare resource utilization. RESULTS The results of this study demonstrated significant improvements in motor symptoms, reduction in motor fluctuations, and enhanced quality of life following PEG-J for LCIG infusion. The treatment was generally well-tolerated, with a low incidence of procedure-related complications. Notably, the use of PEG-J allowed for precise and continuous delivery of LCIG, minimizing variations in drug absorption and ensuring consistent therapeutic levels. CONCLUSIONS Transgastric jejunostomy (PEG-J) offers an effective approach for the continuous infusion of LCIG in Parkinson's disease treatment. This method provides a stable and reliable delivery system, leading to improved symptom control and enhanced quality of life for PD patients.

RESUMEN

Juvenile polyps (JPs) are common, developing mostly as solitary, hamartomatous lesions in the colorectum, and principally affect pediatric patients. Solitary JPs are recognized as benign, with a negligible malignant transformation rate. Primary signet ring cell carcinoma is a rare type of colorectal cancer (0.1%-2.6%) that presents mostly at an advanced stage in younger patients and affects the right-sided colon, with extensive lymphatic invasion and peritoneal dissemination, resulting in a poorer prognosis compared with conventional colorectal cancer. We report a rare case of signet ring cell carcinoma in a solitary JP treated with endoscopic mucosal resection.
