Single port transanal excision for local treatment of rectal lesionsBackground: Since 2009, transanal minimally invasive surgery (TAMIS) is increasingly used as an alternative to local excision and transanal microscopic excision (TEM) for rectal lesions located in the mid and superior third. The clinical benefits of the technique are being evaluated. Aim: To establish the feasibility, quality of excision and short term results of single port transanal excision for rectal lesions. Patients and Methods: Analysis of a prospective series of patients subjected to single port transanal excision. Patients had benign or malignant lesions located in the mid or superior third of the rectum. Those with a diagnosis of adenocarcinoma were excluded. Results: The transanal resection using the SILS Port ® was completed in 11 patients aged 21 to 86 years (eight women). The American Society of Anesthesiologists (ASA) classification of patients was two and their body mass index was 24 ± 3.1 kg/m 2 . The lesion distance from the anal margin ranged from 5 to 10 cm. The surgical time was 47 min and hospital stay was 2.8 days. One patient was converted to conventional transanal surgery and two patients had self-limited episode of hematochezia. Conclusions: TAMIS is a feasible technique and with promising results in selected patients.
Two stage hepatectomy and colectomy among patients with bilateral liver metastases. Report of eight cases Background: Two stage hepatectomy takes advantage of the compensatory regeneration of the liver after a fi rst non curative hepatectomy, to achieve a curative excision in a second intervention. Aim: To report an initial experience with two stage hepatectomy. Material and Methods: Out of sixty four patients who underwent hepatectomy in our institution in the presented period, eight met criteria for colorectal primary and bilateral liver metastatic disease, which we report. Results: Eight patients were subjected to a right portal ligation. In four, a simultaneous metastasis excision in the left lobe was performed. Four to eight weeks later, fi ve were subjected to a right hepatectomy. One patient, that had a relapse of a previous hepatectomy and colectomy, was explored, ligated and afterwards subjected to surgery plus radiofrequency. The six patients that were subjected to excisions were followed for 3 to 39 months. One patient died due to massive pulmonary relapse at 18 months, two were operated again and subjected to radiofrequency, without evidence of residual disease. Two patients have no evidence of relapse and one had a relapse in a rib. Conclusions: In our series, two stage hepatectomy among patients with colorectal cancer and liver metastasis, but its long term results must be evaluated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
