RESUMO
INTRODUCTION: submucosal tunneling endoscopic resection (STER) can be an effective treatment for submucosal tumors (SMTs) in the esophagus and cardia. However, STER may be more difficult to perform in the stomach than in the esophagus due to special anatomical and physiological features. The feasibility of STER to remove gastric STMs has not been systematically investigated. Therefore, this meta-analysis aimed to evaluate the safety and efficacy of STER for gastric SMTs. MATERIAL AND METHODS: a comprehensive literature search of the Medline, Embase, PubMed, and Cochrane Library databases was conducted. Complete resection and en-bloc resection rates were considered as the primary outcome measures. The secondary outcome measure was the pooled estimate of complications. RESULTS: nine studies including 301 patients with 305 lesions were finally included. The pooled estimate of en-bloc resections was 95.1 % (95 % CI: 88.9-97.9 %), Cochran's Q-test, p = 0.151, and the weighted pooled rate (WPR) for complete resection was 97.9 % (95 % CI: 93.6-99.3 %), Cochran's Q-test, p = 0.778. In addition, the pooled estimate of gas-related complications was 8.7 % (95 % CI: 4.6-15.9 %), Cochran's Q-test, p = 0.057. The pooled estimate for mucosal laceration was 4.2 % (95 % CI: 2.2-7.9 %), Cochran's Q-test, p = 0.572. The pooled estimate for delayed bleeding was 2.1 % (95 % CI: 0.9-4.8 %), Cochran's Q-test, p = 0.985. The pooled estimate of inflammation-related complications was 8.6 % (95 % CI: 5.2-13.9 %), Cochran's Q-test, p = 0.308. CONCLUSION: STER is an effective and safe technique for removing gastric SMTs with low complications, and complications, when encountered, can be treated conservatively.

Co-existence of achalasia and SMT is rare. Herein, we presented a case with coexisted achalasia and submucosal tumor, who treated with simultaneous peroral endoscopic myotomy and submucosal endoscopic tunneling resection in the same tunnel.

Background and Aims: Hepatic arterioportal fistulas (HAPFs) are abnormal shunts or aberrant functional connections between the portal venous and the hepatic arterial systems. Detection of HAPFs has increased with the advances in diagnostic techniques. Presence of HAPFs over a prolonged period can aggravate liver cirrhosis and further deteriorate liver function. However, the underlying causes of HAPFs and the treatment outcomes are now well characterized. This study aimed to summarize the clinical characteristics of patients with HAPFs, and to compare the outcomes of different treatment modalities. Methods: Data of 97 patients with HAPFs who were admitted to the Second Xiangya Hospital between January 2010 and January 2020 were retrospectively reviewed. Demographic information, clinical manifestations, underlying causes, treatment options, and short-term outcomes were analyzed. Results: The main cause of HAPF in our cohort was hepatocellular carcinoma (78/97, 80.41%), followed by cirrhosis (10/97, 10.31%). The main clinical manifestations were abdominal distention and abdominal pain. Treatment methods included transcatheter arterial embolization (n=63, 64.9%), surgery (n=13, 13.4%), and liver transplantation (n=2, 2.1%); nineteen (19.6%) patients received conservative treatment. Among patients who underwent transcatheter arterial embolization, polyvinyl alcohol, lipiodol combined with gelatin sponge, and spring steel ring showed comparable efficacy. Conclusions: Hepatocellular carcinoma and cirrhosis are common causes of HAPFs. Transcatheter arterial embolization is a safe and effective method for the treatment of HAPFs, and polyvinyl alcohol, lipiodol combined with gelatin sponge, and spring steel ring showed comparable efficacy in our cohort.
