目的 了解胰十二指肠切除术中良性病例所占比例,分析其病变类型,探讨术前、术中诊断及其它治疗方式的可行性。方法 回顾性分析我院1996～2001年期间206例术前诊断为胰头或壶腹周围恶性肿瘤而作胰十二指肠切除术病例中，术后病理诊断为良性病变者23例的临床、病理资料。结果 术后病理检查发现慢性胰腺炎14例，胰头囊腺瘤2例，十二指肠乳头异位胰腺1例，十二指肠乳头良性腺瘤4例，胆总管下段炎性狭窄2例。良性病变占整个胰十二指肠切除术病例的11.2%。结论 在作胰十二指肠切除术的良性病变中慢性胰腺炎占大多数。术中取活检作冰冻切片病理检查是鉴别良、恶性病变的最有效方法。对这些良性病变可选择保守治疗或行较小的局部切除术。
目的探讨皮瓣鱼网式打孔在乳腺癌根治术后创面覆盖中的应用。方法对80例女性乳腺癌患者行乳腺癌根治术或改良根治术，而后在皮瓣上、下缘予以鱼网式打孔，常规缝合创面。结果全部病例均未植皮，有15例在术后2～5天内有皮瓣血供不良，其余65例均无皮瓣坏死，创面愈合良好。结论皮瓣鱼网式打孔可有效地减小皮瓣缝合张力，减少皮瓣坏死的并发症，可应用于乳腺癌根治术的创面覆盖。
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.
Objective To find a simple, practical and cheap way in suturation to prevent incision complications after celoscope surgery. Methods Using the elastic snell needle to stitch small incision under laparoscopy. Chosed 3 120 cases using the elastic snell needle to stitch stratified suturation as research group, and 3 120 cases by using trditional arc shaped needle in celoscope surgery as control group. The incident rate of incisional hernia and incision bleeding among groups were compared. Results In research group, the incident rate of incision bleeding was 0.16%, among which was 0.15% in epigastrium group, 0.18% in hypogastrium group, while in control group, the incident rate of incision bleeding was 0.68%, among which was 0.64% in epigastrium group, 0.70% in hypogastrium group. The incident rate of incision bleeding was obviously decreased (P＜0.05), and the incident rate of incision bleeding in hypogastrium group was obviously decreased as well (P＜0.05), compared research group and control group. In research group, the incident rate of incisional hernia was 0.07%, among which was 0 in epigastrium group, 0.12% in hypogastrium group, 0.15% in gerontism group, while in control group, the incident rate of incisional hernia was 0.44%, among which was 0.24% in epigastrium group, 0.59% in hypogastrium group, 0.99% in gerontism group, and the incident rate of incisional hernia after surgery was obviously decreased (P＜0.05), the incident rate of incisional hernia after surgery in hypogastrium group was obviously decreased as well (P＜0.05), comparing research group and control group. Conclusions Using the elastic snell needle to stitch small incision under laparoscopy, the peritoneal layer and muscular layer can be apposition sutured in the case without prolonging incision and costing more, hidden hernia and abdominal wall defects located at the incision can be found, ligation and stitched, thereby the incident rate of incisional hernia and incisional bleeding after celoscope surgery are significantly reduced.
