Background: Acute mesenteric ischemia (AMI) is a life-threatening medical condition that occurs when a sudden decreased perfusion to the intestines which leads to bowel infarction, and acute superior mesenteric artery embolism (ASMAE) is the main cause of AMI. Unfortunately, with the improvement of diagnosis and treatment technology, the mortality remains high due to less frequent clinical suspicion resulted from the unclear clinical manifestation and non-specific laboratory findings. Methods: Relevant studies published were identified by searching the PubMed, Embase and Cochrane Library databases. This review presented the literatures to introduce the research progress of ASMAE in recent years. Results: Patients with the history of atrial fibrillation, heart valve disease and atherosclerosis should be considered as ASMAE. Laboratory findings are insensitive and unspecific, however, angiography and Computed tomography angiography (CTA) can provide a clear diagnosis sensitively and specifically. Endovascular approaches have been increasingly reported in multiple case series. The key to successful treatment of AMI involves early clinical recognition and early intervention to move the embolus, which can reduce the rate of misdiagnosis and save the precious time and lives of patients. Conclusions: Loss of time eventually leads to progression of ischemia to transmural bowel necrosis with peritonitis and septicemia, which may further worsen patients’ outcomes. It is important for physicians to make a timely and accurate diagnosis, which can save precious time and reduce the mortality.

BackgroundThe purpose of this study is to compare and evaluate the security and efficacy of 3D vs 2D laparoscopy in rectal cancer treatment.MethodsForty-six patients who suffered from rectal cancer and went on laparoscopic radical resection of rectal carcinoma in Peking University Shougang Hospital from Feb. 2015 to Mar. 2016 were included in the study. They were randomly divided into two groups. The 23 patients operated with the 3D system were compared with 23 patients operated with the 2D system by perioperative data.ResultsThere were no significant differences in age, sex, pathological type, tumor differentiation, TNM staging, and surgical procedures (P > 0.05). The average operating time of 3D laparoscopic surgery group (172.2 ± 27.5 min) was shorter than that of 2D group (192.6 ± 22.3) (P < 0.05); the rate of transfer to laparotomy is lower in 2D group (72.7%) than in 3D group (86.4%), but they have no significant difference; and the intraoperative blood loss (247.0 ± 173.6 ml vs 282.6 ± 195.6 ml), postoperative passage of flatus (2.8 ± 0.8 days vs 3.1 ± 1.0 days), and indwelling catheter time (5.6 ± 1.9 days vs 6.3 ± 2.0 days) in 3D group and 2D group (P > 0.05) were not significantly different. There were no differences in other complications between the two groups. No significantly different recrudescence and death rates were found between the two groups (P > 0.05).ConclusionThe 3D laparoscopy shortens the operation time of rectum cancer. 3D laparoscopic surgery is more efficient in treatment of rectal cancer than 2D laparoscopy and is worth of being generalized.

Adult intussusception during the perioperative period is defined as an extremely rare condition, especially when it emerges within short intervals of laparotomy, which may be explained as an unphysiological peristaltic function of the bowel without any lead points. Accurate diagnosis and therapeutic schedule predict a satisfactory outcome. Here, we introduce the case of a 32-year-old man who had symptoms of abdominal pain, no gas emission, and defecation shortly after liver transplantation. Intussusception was definitely diagnosed by abdominal CT, and then reduction was operated successfully by three-dimensional laparoscopy-assisted operation. There were no other complaints, and no secondary lesions were detected during the postoperative rehabilitation process in the hospital and over a follow-up period of 6 months. Relevant literature has been summarized subsequently. A promising minimally invasive surgery along with minimal secondary trauma was presented by laparoscopy in this rare case, providing the potential remedy for perioperative intussusception in the adult.
