Pancreatoduodenectomy using a no-touch isolation technique.
ABSTRACT Pancreatoduodenectomy is the only effective treatment for cancers of the periampullary region. Because surgeons usually grasp tumors during pancreatoduodenectomy, this procedure may increase the risk of squeezing and shedding the cancer cells into the portal vein, retroperitoneum, and/or peritoneal cavity. In an effort to overcome these problems, we have developed a surgical technique for no-touch pancreatoduodenectomy.
From March 2005 through May 2008, 42 patients have been operated on following this technique. Resected margins were microscopically analyzed.
We describe a technique for pancreatoduodenectomy using a no-touch isolation technique. We resect cancers with wrapping them within Gerota's fascia and transect the retroperitoneal margin along the right surface of the superior mesenteric artery and abdominal aorta without grasping tumors.
No-touch pancreatoduodenectomy has many potential advantages that merit further investigation in future randomized controlled trials.

ABSTRACT: Eighteen patients are reported who have had a regional pancreatectomy. The pancreatic segment of portal vein was excised with en bloc total pancreatectomy and regional lymph node dissection in all 18. Venous repair was by end-to-end anastomosis without a graft. Five of the 18 also had various arterial resections and reconstructions. Sixteen of the 18 had been explored and deemed nonresectable elsewhere. This operation has doubled the resectability rate in this institution. The 30-day operative mortality rate was 16.6%. Acurarial survival is 62% at one year compared with 36% one year survival rate for patients undergoing pancreaticoduodenectomy for less advanced cancer in previous years. A more valid comparison would be between those who had a palliative procedure since most patients in the present series were initially considered unresectable. One year survival for these patients was 22%. The quality of life was good for most patients.Annals of Surgery 08/1977; 186(1):42-50. · 6.33 Impact Factor

ABSTRACT: Postoperative pancreatic fistula (POPF) is still regarded as a major complication. The incidence of POPF varies greatly in different reports, depending on the definition applied at each surgical center. Our aim was to agree upon an objective and internationally accepted definition to allow comparison of different surgical experiences. An international panel of pancreatic surgeons, working in well-known, high-volume centers, reviewed the literature on the topic and worked together to develop a simple, objective, reliable, and easy-to-apply definition of POPF, graded primarily on clinical impact. A POPF represents a failure of healing/sealing of a pancreatic-enteric anastomosis or a parenchymal leak not directly related to an anastomosis. An all-inclusive definition is a drain output of any measurable volume of fluid on or after postoperative day 3 with an amylase content greater than 3 times the serum amylase activity. Three different grades of POPF (grades A, B, C) are defined according to the clinical impact on the patient's hospital course. The present definition and clinical grading of POPF should allow realistic comparisons of surgical experiences in the future when new techniques, new operations, or new pharmacologic agents that may impact surgical treatment of pancreatic disorders are addressed.Surgery 08/2005; 138(1):8-13. · 3.37 Impact Factor

ABSTRACT: Mortality rates associated with pancreatic resection for cancer have steadily decreased with time, but improvements in long-term survival are less clear. This prospective study evaluated risk factors for survival after resection for pancreatic adenocarcinoma. Data from 366 consecutive patients recorded prospectively between November 1993 and September 2001 were analysed using univariate and multivariate models. Fifty-eight patients (15.8 per cent) underwent surgical exploration only, 97 patients (26.5 per cent) underwent palliative bypass surgery and 211 patients (57.7 per cent) resection for pancreatic adenocarcinoma. Stage I disease was present in 9.0 per cent, stage II in 18.0 per cent, stage III in 68.7 per cent and stage IV in 4.3 per cent of patients who underwent resection. Resection was curative (R0) in 75.8 per cent of patients. Procedures included pylorus-preserving Whipple resection (41.2 per cent), classical Whipple resection (37.0 per cent), left pancreatic resection (13.7 per cent) and total pancreatectomy (8.1 per cent). The in-hospital mortality and cumulative morbidity rates were 2.8 and 44.1 per cent respectively. The overall actuarial 5-year survival rate was 19.8 per cent after resection. Survival was better after curative resection (R0) (24.2 per cent) and in lymph-node negative patients (31.6 per cent). A Cox proportional hazards survival analysis indicated that curative resection was the most powerful independent predictor of long-term survival. Resection for pancreatic adenocarcinoma can be performed safely. The overall survival rate is determined by the radicality of resection. Patients deemed fit for surgery who have no radiological signs of distant metastasis should undergo surgical exploration. Resection should follow if there is a reasonable likelihood that an R0 resection can be obtained.British Journal of Surgery 06/2004; 91(5):586-94. · 4.84 Impact Factor
