Objective To analyze the clinical features， common etiologies， prevention measurements of recurrent acute pancreatitis （AP）. Methods The clinical characteristics and imaging examination data of 43 patients with recurrent AP were analyzed retrospectively， which was compared with the results of 258 patients with primary AP. The recurrence etiologies were analyzed. Results There were no significant differences on the fever， jaundice， abdominal pain relief time， pancreatic local complications， and ratio of severe AP between two groups （P＞0.05）. Comparion of etiologies between recurrent AP and primary AP， cholecystitis and diet factor （alcoholic） had priority in patients with primary AP （P=0.038， P=0.006， respectively）， but the hyperlipidemic， duodenal nipple disease， and small stone in the common bile duct were the major etiologies in patients with recurrent AP （P=0.007， P=0.008， respectively）. No relapse was found within the follow up for 3 months to 2 years （the average time was 14.2 months）. Conclusion Find out the exact etiology and performe correct therapy are the key to the treatment and prevention of recurrent AP.
Objective To explore the important role of preperitoneal space in laparoscopic transabdominal preperitoneal （TAPP） and totally extraperitoneal （TEP） hernia repair. Methods The clinical data of 66 patients （78 sides） performed laparoscopic TAPP and TEP hernia repair from January 2008 to April 2011 in this hospital were analyzed retrospectively. Results TAPP hernia repair were performed in 16 cases （20 sides），TEP hernia repair were performed in 50 cases （58 sides）. Three cases of TEP hernia repair transferred to TAPP hernia repair. The unilateral operation time was （86.92±36.38） min，intraoperative bleeding was （6.08±3.43） ml. Postoperative complication rate was 16.7% （11/66），including 3 cases of postoperative serum swelling，3 cases of temporary paraesthesia of nerve feeling in the repair area，2 cases of scrotum emphysema，2 cases of urinary retention，and 1 case of intestinal obstruction. There were 2 cases of recurrence. The hospital stay was （4.52±0.99） d. The return to activities and working time was （10.32±1.86） d after discharge. Sixty-six cases were followed up for （18.56±1.96） months （range 1-38 months），the patch infection，chronic pain，and testicular atrophy complications were not been observed. Conclusions Acquainting and mastering laparoscopic preperitoneal space and its important structure are the key to avoid intraoperative and postoperative complications of laparoscopic inguinal hernia repair.
【Abstract】ObjectiveTo establish the stable model of orthtopic liver transplantation in rats.MethodsIn the light of Kamada’s method, the donor’s liver was perfused through portal vein before it was harvested,and the anastomosis was modified as continous suture with one suture for the suprahepatic inferior vena cava. Two hundred and ten orthotopic liver transplantations were performed in Wistar male rats according to this method. ResultsThe mean time of donor operation was 35 min, and that of recipient operation was 51 min. The mean cold preserving time of graft was 60 min.The anhepatic phase was about 17 min 〔(17.6±4.5) min〕. Nineteen rats died during operation. The causes of death included: bleeding of suprahepatic inferior vena cava, infrahepatic vena cava thrombosis, biliary obstruction, portal vein constriction and thrombosis, liver injury, bleeding of left subphrenic vein, infection, excessively deep anesthesia and respiratory failure. The 24hour survival was 91.0%(191/210),and the oneweek survival was 85.2%（179/210）.ConclusionThrough the modification of the anastomosis of suprahepatic inferior vena cava, the nonhepatic time of the recipients could be shortened,and the complications could be decreased. In this way, the survival of recipient rats after liver transplantation could be increased.
