Robotic and laparoscopic colectomy: propensity score-matched outcomes from a national cancer database.

BACKGROUND: Laparoscopic and robotic approaches to colonic cancer surgery appear to provide similar outcomes. The present study aimed to compare short-term and survival outcomes of laparoscopic and robotic colectomy for colonic cancer. METHODS: This retrospective review of patients with stage I-III colonic cancer who underwent laparoscopic or robotic colonic resection was undertaken using data from the National Cancer Database (2013-2019). Patients were matched using the propensity score matching method. The primary outcome was 5-year overall survival. Secondary outcomes included conversion to open surgery, duration of hospital stay, 30- and 90-day mortality, unplanned readmission, and positive resection margins. RESULTS: The original cohort included 40 457 patients with stage I-III colonic adenocarcinoma, with a mean(s.d.) age of 67.4(12.9) years. Some 33 860 (83.7 per cent) and 6597 (17.3 per cent) patients underwent laparoscopic and robotic colectomy respectively. After matching, 6210 patients were included in each group. Robotic colectomy was associated with marginally longer overall survival for women, and patients with a Charlson score of 0, stage II-III disease or left-sided tumours. The robotic group had a significantly lower rate of conversion (6.6 versus 11 per cent; P < 0.001) and shorter hospital stay (median 3 versus 4 days) than the laparoscopic group. The two groups had similar rates of 30-day mortality (1.3 versus 1 per cent for laparoscopic and robotic procedures respectively), 90-day mortality (2.1 versus 1.8 per cent), 30-day unplanned readmission (3.7 versus 3.8 per cent), and positive resection margins (2.8 versus 2.5 per cent). CONCLUSION: In this study population, robotic colectomy was associated with less conversion to open surgery and a shorter hospital stay compared with laparoscopic colectomy.

Apendicectomia videolaparoscopica com auxilio de grampeador linear cortante / Laparoscopic appendectomy with linear stappler

Apresenta-se a experiencia obtida com 126 doentes submetidos a apendicectomia videolaparoscopica com o uso de grampeador linear cortante. Utilizou-se canula de 12 mm na cicatriz umbilical e 2 canulas de 5 mm, uma no flanco esquerdo e outra na fossa iliaca esquerda, distantes ao redor de 8 cm uma da outra. Em tres casos foi necessaria a conversao por dificuldades de disseccao, mormente em casos de apendices muito friaveis com necrose em estado avancado. Especimes eram retirados da cavidade abdominal dentro de embalagem plastica, evitando o contato com a parede abdominal. Concluiu-se que a apendicectomia videolaparoscopica e procedimento seguro. Permite a limpeza de toda a cavidade abdominal sob visao direta e evita incisoes de maior porte quando o apendice encontra-se em localizacao nao habitual...
