The endoscopic sumucosal disection (ESD) is an advanced endoscopic technique that achieves the curative resection of superficial neoplasms of the gastrointestinal tract, getting block exeresis with margins free of neoplasia avoiding surgery. However, tumors located in the esophagogastric junction, or pylorus, are technically more complex to resect by ESD. When a neoplasm settles in the pylorus, the anatomical characteristics of this region can affect the adequate assessment of the margins and the performance of the procedure...

BACKGROUND: Its relatively low incidence and its surgical complexity mean that a standardized technique for left colectomy has not yet been established for splenic flexure and descending colon cancer (SF-DCC). METHODS: Seventy-three patients (robot-assisted left colectomy with complete mesocolectomy [R-LCCM], n = 20; laparoscopic left colectomy with complete mesocolectomy [L-LCCM], n = 53) with SF-DCC were enrolled at the Asan Medical Center (Seoul, Korea). RESULTS: R-LCCM conveniently enables dexterous dissection for the multi-directional approaches during left mesocolic mobilization...

Introduction: Given the ubiquity of robot-assisted laparoscopic prostatectomy (RALP) for treatment of localized prostate cancer, more surgeons are encountering challenging cases, either secondary to difficult anatomy, prior abdominal surgery, or prior radiation therapy. Our case is of RALP in a patient after prior suprapubic prostatectomy. Case Presentation: A 61-year-old otherwise healthy Hispanic gentleman presented for consultation after being found to have Gleason 4 + 4 = 8 prostate cancer on transrectal ultrasound-guided biopsy by an outside provider in July 2017...

BACKGROUND: Positive surgical margins (PSMs) at radical prostatectomy (RP) are generally recognized as a surrogate of poor or difficult dissection of the prostatic gland. In open RP cohorts, obesity seems to be associated to an increased risk of PSMs, probably due to the technical challenge that obese men pose to surgical access. Minimally invasive RP has been claimed to possibly reduce PSM rate. Aim of the study was to explore the impact of obesity and body habitus on PSM risk and their localisation during laparoscopic and robotic-assisted RP...

BACKGROUND: Reoperation after breast-conserving surgery (BCS) is common and has been partially associated with the lack of consensus on margin definition. We sought to investigate factors associated with reoperations and variation in reoperation rates across breast surgeons at our cancer center. METHODS: Retrospective analyses of patients with clinical stage I-II breast cancer who underwent BCS between January and December 2014 were conducted prior to the recommendation of 'no ink on tumor' margin...

Background and aim: The purpose of breast-conserving surgery (BCS) for women with cancer is to perform an oncological radical procedure with disease-free margins at the final histological assessment and with the best aesthetic result possible. Intraoperative resected specimen ultrasound and intraoperative resected specimen mammography may reduce the rates of positive margins and reexcision among patients undergoing conserving therapy. Our objective is to compare the two methods with the histopathological results for a preset cut off and asses which parameters can influence the positive margin status...

INTRODUCTION: Tracheal adenoid cystic carcinoma (ACC) is rare and accounts for <1% of all lung cancers. Although ACC is classified as a low-grade tumor, metastases are frequently identified in the late period. Extrapulmonary metastases are rare, and their resection has rarely been reported. PRESENTATION OF CASE: Case 1: A 77-year-old man underwent tracheal resection for ACC with postoperative radiation (60 Gy) 14 years before (at the age of 63). He underwent two subsequent pulmonary resections for metastases...
