捆绑式胰肠吻合术100例报告

目的探讨捆绑式胰肠吻合术在胰十二指肠切除术后预防胰肠吻合口漏的临床价值.方法1996年1月～2000年1月间共施行100例捆绑式胰肠吻合术,并与同期94例用传统方法吻合的病例进行对比.捆绑式胰肠吻合手术方法为先将空肠断端向外反摺3cm,将外翻的粘膜用石炭酸破坏3 cm;游离胰断端3 cm,将其断端与距离空肠断端3 cm的空肠粘膜缝合一圈,注意缝针不穿透浆肌层.将反摺的空肠复位后,胰断端就自然进入肠腔之中(长约3 cm),其表面被缺失粘膜的空肠所覆盖,距离断端1 cm用可吸收缝线环绕空肠进行捆绑,令空肠与其腔内的胰残端紧密相贴,然后结扎完成手术,术后观察总体恢复情况,B超定期检查残端有无积液等.结果全组100例,无一例发生胰漏,残端没有积液.结论捆绑式胰肠吻合术十分安全,能够防止胰肠吻合口漏的发生,且操作简单,不论胰腺质地软硬或胰管有无扩张均可使用,值得进一步推广.

Endoscopic transpapillary pancreatic stenting for internal pancreatic fistula with the disruption of the pancreatic ductal system

BackgroundInternal pancreatic fistula (IPF) is a well-recognized complication of pancreatic diseases. Although there have been many reports concerning IPF, the therapy for IPF still remains controversial. We herein report our experiences with endoscopic transpapillary pancreatic stent therapy for IPF and evaluate its validity.MethodSix patients with IPF who presented at our department and received endoscopic transpapillary pancreatic stent therapy were investigated, focusing on the clinical and imaging features as well as treatment strategies, the response to therapy and the outcome.ResultsAll patients were complicated with stenosis or obstruction of the main pancreatic duct, and in these cases the pancreatic ductal disruption developed distal to the areas of pancreatic stricture. The sites of pancreatic ductal disruption were the pancreatic body in five patients and the pancreatic tail in one patient. All patients received endoscopic stent placement over the stenosis site of the pancreatic duct. Three patients improved completely and one patient improved temporarily. Finally, three patients underwent surgical treatment for IPF. All patients have maintained a good course without a recurrence of IPF.ConclusionEndoscopic transpapillary pancreatic stent therapy may be an appropriate first-line treatment to be considered before surgical treatment. The point of stenting for IPF is to place a stent over the stenosis site of the pancreatic duct to reduce the pancreatic ductal pressure and the pseudocyst's pressure.     

Neoadjuvant therapy for pancreatic cancer changes the composition of the pancreatic parenchyma

BackgroundPostoperative pancreatic fistula (POPF) remains a prominent complication following pancreatic cancer resections. The primary aim of this study was to evaluate the histological changes that occur in the pancreas due to neoadjuvant therapy (NAT) by comparing the acinar, collagen and fat scores in resected PDAC specimens of patients who did and did not receive NAT. Secondary aims included (1) the difference in rates of POPF in PDAC patients who received NAT versus upfront resection; and (2) the association between acinar/collagen/fat scores and the development of POPF.MethodsConsecutive patients who underwent pancreaticoduodenectomy for PDAC, with and without NAT were included for analysis. Acinar, collagen and fat scores were determined from histology slides of the pancreatic resection margin.ResultsOne hundred and thirty-four patients were included. There was a significant decrease in the median acinar score (48 vs 23, p = 0.003) and increase in the collagen score (28 vs 50, p = 0.011) for patients who received NAT and a significant correlation with the number of cycles of NAT. This study found no statistical difference between NAT and the development of POPF.ConclusionThe use of NAT in the treatment of PDAC changes the composition of the pancreas.     

Analysis of closure of the pancreatic remnant after distal pancreatic resection

Background. The appropriate management of the pancreatic remnant following distal pancreatic resection remains a clinically relevant problem. We carried out a retrospective analysis which focused on this issue and compared the two favored techniques of suture and staple closure. Patients and methods. Forty-six patients underwent distal pancreatectomy between October 1999 and January 2006. The patients were retrospectively analysed based on the management of the remaining pancreatic gland. Thirty-seven patients had suture and nine patients had staple closure. The morbidity, mortality, incidence of pancreatic fistula, necessity of secondary surgical intervention, and the duration of hospital stay for the two groups were compared. Pancreatic fistula was considered according to the novel international standard definition (ISGPF). In addition, subgroup analysis of patients receiving octreotide was carried out. Results. Overall, postoperative morbidity due to pancreatic fistula occurred in seven patients (19%) after suture and in one patient (11%) after staple closure (p = 0.54), with no deaths. The number of patients with surgical revision related to pancreatic leakage was two (5%) after suture closure vs no revision after staple closure (p = 0.65). The median number of total hospital days for the suture group was 19 (range 7–78 days) vs 21 (range 12–96 days) for the stapler group (p = 0.21). No significant benefit for the octreotide application could be determined. Conclusion. According to the data, no significant difference for either suture or stapler closure was observed, with the tendency for staple closure to be superior.     

Identification of immunoreactive pancreatic stone protein in pancreatic stone, pancreatic tissue, and pancreatic juice

We first examined whether pancreatic stone protein (PSP) was present in pancreatic stone and normal pancreatic tissue. By using HPLC and Western blotting, a protein of Mr 13.5 kDa that reacted with monoclonal antibody against PSP was detected as a major component in EDTA-soluble fractions of pancreatic stone. In an in vitro experiment, this protein dose-dependently suppressed CaCO3 precipitation. PSP was immunohistochemically stained in the acinar cells of normal pancreatic tissue. Based on these findings, it seemed that PSP in pancreatic stone is probably a physiological secretory protein of the pancreas. We subsequently examined immunoreactive PSP in normal pancreatic juice by the Western blotting method. In all of the specimens, the band for immunoreactive PSP in pancreatic juice was found to correspond to 13.5 kDa, which thus agreed with that of purified PSP from a stone.
