Abstract: Due to complicated procedures and severe trauma, esophagectomy still remains an operation with high mortality and morbidity. With the advancement of anesthetic and surgical technique, as well as perioperative management, the mortality and morbidity after esophagectomy decreased significantly in recent years. The optimal perioperative management, normalized and individualized treatment was of importance in preventing postoperative complications and decreasing mortality after esophagectomy. This review summarizes the current state of perioperative management for esophagectomy.

Purpose To investigate the pattern of subretinal neovascular membrane(SRNVM)in central exudative chorioretinitis(CEC). Methods With the help of a PC microcomputer,we performed a quantitative measurement of SRNVM in 32 eyes of 32 patients with Rieger is CEC. Results SRNVM-optic disc area ratio were 0.1151plusmn;0.0842．The foveola was on the top of SRNVM in 7 cases．The other 25 of SRNVMs were scattered in macular area around foveola,and 2 of them were nasal to it．The distance between the edge of SRNVM and foveola was less than 175mu;m in 13 cases,175～300mu;m in 4 cases and more than 300mu;m in 15 cases． Conclusion To be compared with the previous data,the present results suggested that laser photocoagulation might be one of the most important therapies for SRNVM in Rieger is CEC． (Chin J Ocul Fundus Dis,1998,14:114-115)
ObjectiveTo investigate the occurrence and treatment of postoperative complications after laparoscopic laparoscopic pylorus-preserving pancreaticoduodenectomy (LPPPD) or pancreaticoduodenectomy (LPD). MethodThe clinical data of 130 patients undergoing LPD from October 2010 to December 2015 in West China Hospital of Sichuan University were analyzed retrospectively. ResultsOf 130 patients, postoperative complications occurred in 55 cases, including 24 cases of pancreatic fistula, 14 cases of gastric emptying disorder, 3 cases of anastomotic bleeding, 6 cases of peritoneal infection, 1 case of bile leakage, 1 case of venous thrombosis, 1 case of chylous leakage, 5 cases of peritoneal effusion, without the occurrence of stress ulcer and incision complications. There were significant difference in the incidence of pancreatic fistula (P=0.025), gastric emptying disorder (P=0.034), anastomotic bleeding (P=0.020), and peritoneal infection (P=0.016) among prophase group, metaphase group, and the later stage group. ConclusionsThe most common complication after LPD is pancreatic fistula. With the improvement of surgical techniques and procedures, incidences of some postoperative complications decreases gradually.
ObjectivesTo explore the mechanisms by which ischmic preconditioning (IPC), ischemic postconditioning (IPO) and IPCIPO exert influence on ischemic reperfusion injury (IRI) of the graft of SD rat after pancreas transplantation. MethodsAfter the establishment of diabetic SD rats model by using streptozotocin, 24 rats suffered from pancreas transplantation and were randomly averagely divided into four groups: I/R group, IPC group, IPO group, and IPC-IPO group. Six diabetic SD rats suffered with sham operation were served as SO group. The blood glucose level of rats in each group was detected before and after reperfusion, the contents of malonaldehyde (MDA) and super oxide dismutase (SOD) of pancreas allograft were tested at 2 h after reperfusion, and the apoptosis index (AI) of pancreas allograft was monitored by using TUNEL method. ResultsThe blood glucose level of rats in each group was not significantly different (Pgt;0.05). In SO group, the blood glucose level of rats was significantly higher than other groups (Plt;0.01). The blood glucose levels of rats after reperfusion decreased from the levels before reperfusion in I/R group, IPC group, IPO group, and IPC-IPO group (Plt;0.05 or Plt;0.01), furthermore the blood glucose level of rats in I/R group was significantly higher than that in abovementioned three groups (Plt;0.01), although among which the difference was not markedly (Pgt;0.05). When compared with I/R group, the MDA contents of rats after reperfusion in IPC group, IPO group， and IPC-IPO group decreased (Plt;0.01), while the SOD contents of rats after reperfusion increased (Plt;0.01). In rats of SO group, the MDA and SOD contents were significantly higher and lower than other groups, respectively (Plt;0.01). The MDA and SOD contents in IPC group, IPO group, and IPC-IPO group were not different (Pgt;0.05). The AI of pancreas allograft at 2 h after reperfusion in I/R group 〔(47.31±4.52)%〕, IPC group 〔(26.25±3.17)%〕, IPO group 〔(24.73±3.62)%〕, and IPC-IPO group 〔(25.5±4.15)%〕 were higher than that in SO group 〔(3.16±0.53)%〕, Plt;0.01. The AI of pancreas allograft in IPC group, IPO group, and IPC-IPO group were not different (Pgt;0.05), but they were lower than that in I/R group (Plt;0.01). Pathological results showed that injury of pancreas allograft in I/R group was most severe. ConclusionsIPO and IPC are associated with comparable effectiveness to protect graft from IRI during pancreas transplantation. The combined protective effects of IPC and IPO do not appear to be additive, which is equal to IPC or IPO alone.

Methods: Seventyone cases above 60 years with Obstructive Colorectal Cancer were analysed retrospectively on their individual accompanied diseases and perioperative treatments, from 2003 to 2008.Results: Fortythree cases of them had suffered from other diseases. Midoperative complications occurred in 19 cases. Postoperative complications occurred in 37 cases. Except 5 cases of death, complications occurring in others cases were well controlled. The death causes mainly were correlated with accompanied chronic diseases. Conclusion: Strengthen care, active management of other chronic diseases are important significantly for senile patients with colorectal carcinoma to get satisfied outcome.
