REVIEW
Yongbo An, Kai Shen, Yingjiang Ye
Postoperative acute kidney injury in patients undergoing abdominal surgery is not rare and often results in bad outcomes for patients. The incidence of postoperative acute kidney injury is hard to evaluate reliably due to its non-unified definitions in different studies. Risk factors for acute kidney injury specific to abdominal surgery include preoperative renal insufficiency, intraabdominal hypertension, blood transfusion, bowel preparation, perioperative dehydration, contrast agent and nephrotoxic drug use...

Lymph node dissection is a critical part of surgery for colorectal cancer. Japanese D3 and complete mesocolic excision are two unique principles for lymph node dissection in colorectal cancer. Laparoscopic surgery magnifies the targets and provides insight about the micro-anatomy through high-quality, high-definition imaging, which benefits the surgeon. Although laparoscopic colorectal resection is feasible, there is no universal procedure. We describe in detail the anatomy viewed during lymph node dissection around the inferior mesenteric artery...
