Laparoscopic surgery contributes to a decrease in short-term complications in surgical ulcerative colitis patients during 2008–2017: a multicenter retrospective study in China

Background/Aims@#The aim of this study was to analyze the chronological changes in postoperative complications in surgical ulcerative colitis patients over the past decade in China and to investigate the potential parameters that contributed to the changes. @*Methods@#Ulcerative colitis patients who underwent surgery during 2008–2017 were retrospectively enrolled from 13 hospitals in China. Postoperative complications were compared among different operation years. Risk factors for complications were identified by logistic regression analysis. @*Results@#A total of 446 surgical ulcerative colitis patients were analyzed. Fewer short-term complications (24.8% vs. 41.0%, P=0.001) and more laparoscopic surgeries (66.4% vs. 25.0%, P<0.001) were found among patients who received surgery during 2014–2017 than 2008–2013. Logistic regression suggested that independent protective factors against short-term complications were a higher preoperative body mass index (odds ratio [OR], 0.870; 95% confidence interval [CI], 0.785–0.964; P=0.008), laparoscopic surgery (OR, 0.391; 95% CI, 0.217–0.705; P=0.002) and elective surgery (OR, 0.213; 95% CI, 0.067–0.675; P=0.009). The chronological decrease in short-term complications was associated with an increase in laparoscopic surgery. @*Conclusions@#Our data revealed a downward trend of short-term postoperative complications among surgical ulcerative colitis patients in China during the past decade, which may be due to the promotion of minimally invasive techniques among Chinese surgeons.

Surgical treatment for right colon cancer directly invading the duodenum.

Right colon carcinoma with duodenal invasion is rare, and optimal management remains controversial. Twenty patients demonstrating right-colon carcinoma directly invading the duodenum presented at the Second Xiangya Hospital between 1990 and 2006. Different surgical management strategies were selected based on duodenal involvement, and patient outcomes were evaluated. There was no perioperative death in this series, but three major complications presented during the perioperative period: one case of duodenal stenosis and two duodenal leaks due to gastric or duodenal drainage. Eight of 13 patients treated by en bloc resection survived more than 3 years, including one 10-year survivor and four 5-year survivors. Of the seven patients treated with palliative resection, no patients survived more than 18 months. In conclusion, duodenal invasion by a right-sided colon carcinoma does not necessarily represent incurable disease. If carefully applied based on the extent of duodenal invasion, active surgical management is very useful for improving patient prognosis without increasing the risks associated with surgery.

Study on the expressions of chemotactic proteins and their significance in pancreatic carcinoma and chronic pancreatitis / 中国普通外科杂志

Objective To investigate the expressions of IL-8,MCP-1 and MIP-1? and their biological significance in pancreatic carcinoma and chronic pancreatitis, and investigate the relationships of their expressions in pancreatic cancer tissues.Methods Immunohistochemical method of avidin-biotin complex was used to examine surgically removed specimens from 51 cases of pancreatic carcinoma and 10 cases of chronic pancreatitis. Results The positive rates of expression and the scorings of IL-8,MCP-1,MIP-1? were significantly higher in pancreatic carcinoma than that in chronic pancreatitis(P
