RESUMO
BACKGROUND: Solitary hamartomatous polyps (SHPs) are rare lesions. Endoscopic full-thickness resection (EFTR) is a highly efficient and minimally invasive endoscopic procedure that benefits from complete lesion removal and high safety. CASE SUMMARY: A 47-year-old man was admitted to our hospital after experiencing hypogastric pain and constipation for over fifteen days. Computed tomography and endoscopy revealed a giant pedunculated polyp (approximately 18 cm long) in the descending and sigmoid colon. This is the largest SHP reported to date. Having considered the condition of the patient and mass growth, the polyp was removed using EFTR. CONCLUSION: On the basis of clinical and pathological evaluations, the mass was considered an SHP.
RESUMO
BACKGROUND: Though robot-assisted minimally invasive esophagectomy (RAMIE) is demonstrated to offer a better visualization and provide a fine dissection of the mediastinal structures to facilitate the complex thoracoscopic operation, the superiorities of RAMIE over MIE have not been well verified. The aim of this study was to explore the actual superiorities through comparing short-term results of RAMIE with that of MIE. METHODS: PubMed, EMBASE and web of science databases were systematically searched up to September 1, 2020 for case-controlled studies that compared RAMIE with TLMIE. RESULTS: Fourteen studies were identified, with a total of 2,887 patients diagnosed with esophageal cancer, including 1,435 patients subjected to RAMIE group and 1,452 patients subjected to MIE group. The operative time in RAMIE was still significantly longer than that in MIE group (OR =0.785; 95% CI, 0.618-0.952; P<0.001). The incidence of pneumonia was significantly lower in RAMIE group compared with MIE group (OR =0.677; 95% CI, 0.468-0.979; P=0.038). CONCLUSIONS: RAMIE has the superiorities over MIE in short-term outcomes in terms of pneumonia and vocal cord palsy. Therefore, RAMIE could be considered as a standard treatment for patients with esophageal cancer.
