RESUMO
A best evidence topic in surgery was written according to a structured protocol. The question addressed how subintimal angioplasty (SIA) compares to transluminal angioplasty (TA) for the treatment of femoral occlusive disease. One hundred and thirty two papers were found using the reported search; the 5 which represented the best evidence to answer the question are discussed. The evidence on this subject is limited; there are no randomised controlled trials (RCTs) comparing SIA to TA for pathologically equivalent lesions. However SIA remains a safe and effective alternative to surgical bypass grafting when TA cannot be performed.

A best evidence topic in surgery was written according to a structured protocol. The question addressed whether there is any benefit in treating infected laparotomy wounds with negative pressure wound therapy (NPWT). Forty-five papers were found using the reported search; of which 4 represented the best evidence to answer the question. The evidence on this subject is limited; there is a single non-randomised controlled trial, 2 prospective cohort studies, and 1 retrospective cohort study discussed in this paper. From the available literature, the use of NPWT in infected laparotomy wounds does reduce the length of hospital stay, the number of dressing changes required and promote faster wound healing.

A best evidence topic in vascular surgery was written according to a structured protocol. The question addressed whether endovascular treatment improved peri-operative outcomes when compared to an open approach to restore arterial perfusion in acute mesenteric occlusive disease. Four hundred and ninety seven papers were identified using the reported search; of which 4 represented the best evidence to answer the question and are discussed. The evidence on this subject is limited, comprising largely of non-randomised retrospective cohort studies. The evidence suggests that endovascular treatment is associated with reduced mortality and has better short-term peri-operative outcomes, as well as longer-term survival - however many endovascular cases require subsequent open surgery. There is also conflicting evidence to suggest endovascular therapy is associated with longer ICU stays. Aside from procedural complications, factors such as patient status, time delay to diagnosis and treatment may play a greater role in determining mortality rates. In summary, endovascular therapy appears to be a feasible treatment option with post-operative complications and inpatient mortality rates lower than those seen in open surgery.
