  • Influence of Pancreatoduodenectomy on CD4+CD25+ T Cells in Patients with Pancreatic Head Carcinoma and Its Clinical Significance

    ObjectiveTo investigate the proportion of peripheral blood CD4+CD25+ regulatory T cells (Tregs) in patients with pancreatic head carcinoma, the dynamic changes of these cells before and after pancreatoduodenectomy were also analyzed. MethodsThe proportions of peripheral blood CD4+CD25+ Tregs in patients with pancreatic head carcinoma and normal individuals were examined by using flow cytometric analysis. The CD4+/CD8+ ratio was also studied before and after operation. ResultsThe patients with pancreatic head carcinoma showed higher ratio of CD4+CD25+ and CD4+CD25high Tregs compared with normal control before operation (Plt;0.05). However, the percentage of these T cells reduced significantly after pancreatoduodenectomy, which was most obviously on the 3rd day after operation (Plt;0.01, Plt;0.05). After operation, CA199 level began to decrease, which was obvious on the fourteen day after operation. This tendency of CD4+CD25high Tregs changes was similar to that of CA199. The patients showed an decreased ratios of CD4+/CD8+ compared with normal controls, which further declined after operation, and reached the lowest point on the seventh day after operation (Plt;0.05). ConclusionsPancreatoduodenectomy may be helpful for the recovery of antitumor immunity. The perioperative period of patients with pancreatic head carcinoma may be a beneficial windowphase for immune intervention and Tregs may be served as target cells.

  • Management of Hemorrage Related to Pancreatic Fistula after Pancreaticoduodenectomy (Report of 2 Cases )

    目的 探讨胰十二指肠切除术后胰瘘引起腹腔大出血行外科治疗的可行性。方法 在343例行胰十二指肠切除术的患者中,2例术后发生严重的胰瘘伴有腹腔大出血,均再次手术行胰肠分离式桥式内引流术。结果 经术后支持治疗、持续腹腔冲洗、抑制胰酶分泌,治疗成功,顺利出院。术后随访18个月,没有胰管梗阻和脱落的迹象。患者没有发生糖尿病。结论 胰十二指肠切除术后胰瘘导致的腹腔大出血治疗非常困难,通过外科再手术行胰肠分离式桥式内引流术,取得成功,避免了复杂的全胰切除,挽救了胰腺功能,提高了患者的成功救治机会,改善了患者术后的生活质量。

  • Application of Purse-String Invaginated Double-Layer Anastomosis of Pancreaticojejunal in Pancreaticoduodenectomy

    Objective To evaluate the application of a surgical method in pancreaticoduodenectomy. Methods All the 211 cases of purse-string invaginated pancreaticojejunostomy performed from Dec.1985 to Dec.2007 were reviewed. Firstly, an accordant plastic tube was put and fastened in main pancreatic duct, and pancreas was ligated at 2-3 cm apart from the pancreatic stump to let secretin flow far away. Furthermore, invaginated pancreaticojejunostomy was performed to get closer between pancreas and jejunum. Results Pancreatic fistula and perioperative death didn’t occur among these 211 cases. The complications included 2 cases of incision dehiscence, 4 cases of biliary fistula and 1 case of scission of superior mesentric artery. Conclusion Purse-string invaginated double-layer anastomosis of pancreaticojejunal would be feasible for pancreaticoduodenectomy preventing pancreatic fistula.

  • Application of Growth Hormone in Senile Patients after Pancreaticoduodenectomy

    Objective To explore the effects of recombinant human growth hormone (rhGH) on senile patients after pancreaticoduodenectomy. MethodsFortysix patients were divided into the therapeutic group (rhGH, n=17) and control group (n=29). Both were treated with parenteral nutrition. In the therapeutic group, rhGH (8 u/d) was given hypodermically for 7 days. After operation the levels of albumin, prealbumin, transferrin, and immunoglobulin were measured. Postoperative fatigue syndrome and the average length of stay in hospital were observed too. ResultsAfter operation the levels of albumin, prealbumin, transferrin, and immunoglobulin in the therapeutic group were significantly higher than those of control group. The degree of postoperative fatigue syndrome in the therapeutic group was less than that of control group. The average length of stay in hospital was significantly shortened. Conclusion The early application of rhGH in senile patients after pancreaticoduodenectomy can enhance immune function, reduce the incidence of infection, promote the postoperative recovery, shorten the average length of stay in hospital,decrease the mortality, increase the safety of operation and improve the postoperative life quality of senile patients.

  • Clinical Analysis of Patients with Benign Diseases Undergoing Pancreaticoduodenectomy

    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。

  • Clinical Analysis of 39 Cases with Hemorrhage after Pancreatoduodenectomy

    目的 探讨胰十二指肠切除术后出血的原因及其预防和治疗措施。方法 对我院1977~2002年期间210例胰十二指肠切除术病例进行回顾性分析。结果 发生术后出血39例(18.6%),其中上消化道出血33例次(15.7%),腹腔内出血10例次(4.8%)。术后死亡的18例中14例合并术后出血; 出血合并其他并发症患者的死亡率(57.1%,12/21)明显高于单纯出血病例(11.1%,2/18),与出血并存的并发症中以吻合口漏、腹腔内感染和肝、肾功能衰竭最为常见。近两年来术后出血率(10.5%)较90年代(19.8%)和90年代前(26.2%)减少。术后出血患者术前总胆红素≥342 μmol/L者的比例及术中出血和输血量均明显高于未出血病例。结论 精细熟练的操作、严密吻合、彻底止血及有效预防其他并发症的发生是减少术后出血及死亡的关键,术前重度黄疸、术中大量出血和输血将增加患者术后出血的危险性。

  • Modified Method of Binding Pancreaticoenterostomy ( Report of 8 Cases)

    目的 探讨捆绑式胰肠吻合术的改良方法。方法 对8例胰十二指肠切除术患者行捆绑式胰肠吻合术时采用带血管蒂的大网膜包绕空肠浆肌鞘,以达捆绑之目的。8例中行桥袢空肠造瘘5例,胆总管造口T管引流3例,并观察其术后5 d内每天平均引流液量。结果 8例患者均治愈出院,无胰瘘、胆瘘发生; 5 d内每天平均引流液量除第1天胆总管造口低于空肠造瘘外,其余4 d每天平均引流液量均明显高于空肠造瘘; 1例空肠造瘘者术后第8天继发胰腺残端出血,经电灼后止血。结论 带血管蒂的大网膜包绕空肠浆肌鞘完全可以代替粗线环绕空肠结扎,并使整个空肠浆肌鞘与胰腺紧贴,更利于胰肠间愈合; 空肠造瘘或胆总管造口对桥袢空肠均有减压引流的作用,但T管引流更简单、有效、省时。
