ObjectiveTo explore the risk factors of recurrence of incisional hernia following incisional hernia tension-free repair.
MethodsThe clinical data of 162 patients with incisional hernia underwent tension-free repair were retrospectively analyzed in this hospital from January 2005 to January 2011. The relationships of incisional hernia recur-rence to gender, age, body mass index, hernia size, abdominal wall defect site, preoperative chronic comorbidities, type of tension-free repair, operation time, and wound healing disorders were analyzed by univariate and multivariate analysis.
ResultsOne hundred and sixty-two patients were followed up 7-70 months with mean 34.5 months. The rate of recur-rence following incisional hernia tension-free repair was 9.26% (15/162). The results of univariate analysis showed that recurrence following incisional hernia tension-free repair was associated with the age (P < 0.05), body mass index (P < 0.05), type of tension-free repair (P < 0.05), hernia size (P < 0.05), and wound healing disorders (P < 0.05). The results of multivariate logistic regression revealed that the body mass index, type of tension-free repair, hernia size, and wound healing disorders were the independent risk factors associated with recurrence following incisional hernia tension-free repair. Fifteen recurrent patients were reperformed successfully. There was no recurrence following up with an average 23 months.
ConclusionsIt is necessary to become familiar with the risk factors for recurrence of incisional hernia in order to eliminate or decrease their effects on the positive outcome of incisional herniorrhaphy. The patients with fat, hernia ring bigger, incorrect opera-tion or wound healing disorders might be easy to relapse. Surgical approach should be individualized for recurrence.
ObjectiveTo analyze the risk factors of postoperative cognitive dysfunction (POCD) in elderly patients after abdominal surgery. MethodsThe clinical data of 2 286 patients over 60 years old after abdominal surgery were retrospectively analyzed, which were divided into non-POCD group with 2 248 patients and POCD group with 38 patients. The influencing factors of POCD in elderly patients after abdominal surgery, including the age, gender, anesthetic way, the premedication, cormobided with lung or heart disease, diabetes, jaundice, anemia or hypoproteinemia, the duration of surgery, and postoperative analgesia protocols, were analyzed between two groups. ResultsThe age, anesthetic way, cormobided with lung or heart disease, diabetes, jaundice, with or without continuous postoperative effective analgesia, and surgery duration over four hours were relevant with POCD (Plt;0.05), while gender, the premedication, and preexisted anemia or hypoproteinemia were not relevant with that (Pgt;0.05). ConclusionAge over 70 years, general anaesthesia, cormobided with lung or heart disease, diabetes, jaundice, surgery duration over four hours, and incomplete postoperative analgesia are the risk factors of POCD after abdominal surgery.
ObjectiveTo summarize the research progress of correlation between pancreatic cancer and diabetes mellitus.MethodsRecent studies on the association between pancreatic cancer and diabetes mellitus were extensively reviewed, and relevant research results on the association between pancreatic cancer and diabetes mellitus were reviewed.ResultsPancreatic cancer had a particular association with diabetes. Patients with pancreatic cancer may develop new diabetes or worsen existing diabetes mellitus. About 50% of patients with pancreatic cancer had diabetes mellitus before diagnosis, suggesting a “dual causal relationship” between pancreatic cancer and diabetes mellitus. Long-term type 2 diabetes mellitus (T2DM) was one of the high risk factors for the occurrence and development of pancreatic cancer. T2DM may also increase the risk of pancreatic cancer due to hyperinsulinemia, adipokine, and other factors. Pancreatic cancer was one of the cause of diabetes mellitus at the same time, but its mechanism was not yet known, also needed to get a lot of information to understand the impact of long-term diabetes mellitus on the development of pancreatic cancer, as well as the reason of pancreatic cancer related to diabetes mellitus mechanism.ConclusionThe clear relationship between pancreatic cancer and diabetes mellitus has not been proved, and further research is needed to clarify the relationship between them.

Methods We retrospectively analyzed the clinical data of 2 559 patients who underwent non-gastroduodenal abdominal surgeries in our hospital between September 2004 and March 2010. We divided them into the PGS group with 23 patients and the non-PGS group with 2 536 patients. Results By comparing the age, the gender, the starting time of eating after surgery, the duration of surgery, whether the patients had advanced cancer, whether anemia or hypoproteinemia existed, whether the patients had a history of previous abdominal surgery, and whether nutritional support was provided early after operation between the PGS group and the non-PGS group, we found that the chi-square value was 19.687, 0.018, 0.346, 48.243, 21.801, 16.803, 24.679, 0.870 and the P value waslt;0.01, gt;0.05, gt;0.05, lt;0.01, lt;0.01, lt;0.01, lt;0.01, gt;0.05 respectively. Conclusion Over 65 years of age, the duration of surgery over four hours, advanced cancer, the history of previous abdominal surgery and anemia or hypoproteinemia are the risk factors of PGS after non-gastroduodenal abdominal surgery.
Objective To investigate the correlated risk factors of deep venous thrombosis (DVT) after the laparoscopic surgery. Methods Clinical records of 16 patients with DVT and 148 patients without DVT after laparoscopic surgery in Huashan hospital from Mar.2007 to Jan.2008 were analyzed retrospectively. Results There were several factors which could induce DVT after the laparoscopic surgery, including operation time ＞1 h 〔OR=4.15 （95% CI： 1.36-12.68）〕, operative site located in hypogastrium 〔OR=2.94 （95% CI： 1.07-8.08）〕 and the number of high risk factors ≥3 〔OR=3.94 （95% CI： 1.38-11.23）〕. Conclusions The long time of operation， hypogastric operation of laparoscopic surgery and high risk factors could induce DVT. Prevention measures should be made in preoperative period.

Objective To investigate the risk factors for early progression in patients with acute respiratory distress syndrome (ARDS), and to provide a reference for early detection and intervention of high-risk patients with ARDS progression. Methods Data from multicenter mechanically ventilated patients with mild to moderate ARDS were retrospectively analyzed. According to the severity grade of 72 h ARDS, the patients were divided into an early progressive group and a non-progressive group. Chi-square test was used to compare the risk factors of ARDS patients and the prognosis of the two groups were analyzed by Logistic regression. Results A total of 355 patients with mild to moderate ARDS were included in invasive mechanical ventilation, of which 97 patients (27.3%) progressed after 72 hours. 78.4% were female in the progressive group and 64.0% were female in the non-progressive group. Compared with the non-progressive group, the patients with ARDS in the progressive group had shorter 28-day no mechanical ventilation, higher ICU mortality, and lower survival rate at 30 days and 60 days（P<0.05）, but there was no significant difference in the length of ICU stay between the two groups (P>0.05). Univariate and multivariate regression analysis showed that the patients with ARDS in the progressive group had lower baseline oxygenation index (OR=0.979, 95%CI 0.961 - 0.986, P<0.01), higher peak airway pressure (OR=1.068, 95%CI 1.017 - 1.121, P<0.01), higher lactate level (OR=1.224, 95%CI 1.057 - 1.417, P<0.01), higher tidal volume (OR=1.159, 95%CI 1.002 - 1.341, P<0.05), higher age (OR=1.373, 95%CI 1.051 - 1.082, P<0.01), and more male patients (OR=2.583, 95%CI 1.336 - 4.995, P<0.05). Conclusions Early progression is common in mild to moderate ARDS patients with mechanical ventilation. The progressive group has shorter duration of 28 days without mechanical ventilation, higher ICU mortality and lower 30-day and 60-day survival rate than the non-progressive group. Male, low baseline oxygenation index levels, high peak airway pressure, tidal volume, lactate levels, and higher age are risk factors for early progression in patients with mild to moderate ARDS.
Clinical scientists have paid more and more attention to the acute respiratory distress syndrome(ARDS), a severe complication after thoracotomy, for its high mortality rate. Compared with other surgical patients, patients who received thoracotomy often have a worse cardiopulmonary function and are prone to suffering from ARDS. Surgical treatment or injury, massive blood transfusion, respiratory tract infection, improper fluid replacement and ventilation are probable reasons to cause ARDS. Mechanical ventilation is an important treatment for ARDS，but ventilation with lungprotective strategies was proved to be the only therapy which can improve the prognosis of patients with ARDS. At present, thinking highly of and promoting the perioperative management, lessening surgical injury and active prevention are still very important measures to reduce the mortality after thoracotomy. This article is aimed to review the high risk factors of ARDS after thoracotomy as well as its treatment.
