Introduction: In an attempt to further enhance the benefits of cosmesis and reduced morbidity of minimally invasive surgery, single‐port (incision) laparoscopic surgery (SPS) has emerged as a bridge between conventional laparoscopy and natural orifice transluminal endoscopic surgery. As the expertise and instrumentation required are an extension of standard laparoscopic techniques, SPS has been adapted for a variety of procedures and specialties in a short span of time. Discussion: In this article, we discuss the various SPS techniques, as well as the new devices and instrumentation available for facilitating SPS. We also review current applications reported for SPS in various surgical specialties. We present a comprehensive review of the potential benefits, limitations and risks of these novel techniques. Conclusion: Initial reports have demonstrated the technical feasibility and safety of SPS for a wide range of surgical applications. With specialized instrumentation and refinement of technique, its role will increase in coming years. Future work is necessary to improve existing instrumentation, to increase clinical experience and to assess the benefits of this surgical approach.  相似文献

Background  

The genetic basis of tropical calcific pancreatitis (TCP) is different and is explained by mutations in the pancreatic secretory trypsin inhibitor (SPINK1) gene. However, mutated SPINK1 does not account for the disease in all the patients, neither does it explain the phenotypic heterogeneity between TCP and fibro-calculous pancreatic diabetes (FCPD). Recent studies suggest a crucial role for pancreatic renin-angiotensin system during chronic hypoxia in acute pancreatitis and for angiotensin converting enzyme (ACE) inhibitors in reducing pancreatic fibrosis in experimental models. We investigated the association of ACE gene insertion/deletion (I/D) polymorphism in TCP patients using a case-control approach. Since SPINK1 mutations are proposed a modifier role, we also investigated its interaction with the ACE gene variant.  相似文献

It is well established that weight loss in general and bariatric surgery in particular can improve glycaemic control in diabetics. Current NICE guidelines recommend that those patients with type 2 diabetes mellitus and a BMI of 35 kg/m2 or more should be considered for bariatric surgery in order to optimise their glycaemic control and minimise their risk of long-term complications. The commonest bariatric procedure in the UK is the Roux-en-Y gastric bypass that has been shown to result in long-standing type 2 diabetes resolution in 83 % of patients. Since such surgery carries a small but significant risk of mortality, as well as posing considerable lifestyle implications for the patient, numerous studies have been performed with a view to identifying which patients and which procedures are most likely to result in these desired benefits. This paper summarises the existing literature on this topic.  相似文献
