RESUMO

As the population in the United States ages, an increasing number of elderly patients may be considered for pancreaticoduodenal resection. This high-volume, single-institution experience examines the morbidity, mortality, and long-term survival of 727 patients undergoing pancreaticoduodenectomy between December 1986 and June 1996. Outcomes of patients 80 years of age and older (n = 46) were compared to those of patients younger than 80 years. In these older patients, pancreaticoduodenectomy was performed for pancreatic adenocarcinoma (n = 25; 54%), ampullary adenocarcinoma (n = 9; 20%) distal bile duct adenocarcinoma (n = 5; 11%), duodenal adenocarcinoma (n = 2; 4%), cystadenocarcinoma; (n = 2; 4%), cystadenoma (n = 1; 2%), and chronic pancreatitis (n = 2; 4%). When compared to the 681 concurrent patients younger than 80 years who were undergoing pancreaticoduodenectomy, the two groups were statistically similar with respect to sex, race, intraoperative blood loss, and type of pancreaticoduodenectomy performed. Patients 80 years of age or older had a shorter median operative time (6.4 hours vs. 7.0 hours; P = 0.02) but a longer postoperative length of stay (median = 15 days vs. 13 days; P = 0.01) and a higher complication rate (57% vs. 41%; P = 0.05) when compared to their younger counterparts. Pancreaticoduodenectomy in the older group resulted in a 4.3% perioperative mortality rate compared to 1.6% in the younger group (P = NS). In the subset of patients undergoing pancreaticoduodenectomy for periampullary adenocarcinoma (n = 495), patients 80 years of age or older (n = 41) had a median survival of 32 months and a 5-year survival rate of 19%, compared to 20 months and 27%, respectively, in patients younger than 80 years (n = 454; P = 0.77). These data demonstrate that pancreaticoduodenectomy can be performed safely in selected patients 80 years of age or older, with morbidity and mortality rates approaching those observed in younger patients. Based on these data, age alone should not be a contraindication to pancreaticoduodenectomy.

RESUMO

OBJECTIVE: The authors reviewed the pathology, complications, and outcomes in a consecutive group of 650 patients undergoing pancreaticoduodenectomy in the 1990s. SUMMARY BACKGROUND DATA: Pancreaticoduodenectomy has been used increasingly in recent years to resect a variety of malignant and benign diseases of the pancreas and periampullary region. METHODS: Between January 1990 and July 1996, inclusive, 650 patients underwent pancreaticoduodenal resection at The Johns Hopkins Hospital. Data were recorded prospectively on all patients. All pathology specimens were reviewed and categorized. Statistical analyses were performed using both univariate and multivariate models. RESULTS: The patients had a mean age of 63 +/- 12.8 years, with 54% male and 91% white. The number of resections per year rose from 60 in 1990 to 161 in 1995. Pathologic examination results showed pancreatic cancer (n = 282; 43%), ampullary cancer (n = 70; 11%), distal common bile duct cancer (n = 65; 10%), duodenal cancer (n = 26; 4%), chronic pancreatitis (n = 71; 11%), neuroendocrine tumor (n = 31; 5%), periampullary adenoma (n = 21; 3%), cystadenocarcinoma (n = 14; 2%), cystadenoma (n = 25; 4%), and other (n = 45; 7%). The surgical procedure involved pylorus preservation in 82%, partial pancreatectomy in 95%, and portal or superior mesenteric venous resection in 4%. Pancreatic-enteric reconstruction, when appropriate, was via pancreaticojejunostomy in 71% and pancreaticogastrostomy in 29%. The median intraoperative blood loss was 625 mL, median units of red cells transfused was zero, and the median operative time was 7 hours. During this period, 190 consecutive pancreaticoduodenectomies were performed without a mortality. Nine deaths occurred in-hospital or within 30 days of operation (1.4% operative mortality). The postoperative complication rate was 41%, with the most common complications being early delayed gastric emptying (19%), pancreatic fistula (14%), and wound infection (10%). Twenty-three patients required reoperation in the immediate postoperative period (3.5%), most commonly for bleeding, abscess, or dehiscence. The median postoperative length of stay was 13 days. A multivariate analysis of the 443 patients with periampullary adenocarcinoma indicated that the most powerful independent predictors favoring long-term survival included a pathologic diagnosis of duodenal adenocarcinoma, tumor diameter <3 cm, negative resection margins, absence of lymph node metastases, well-differentiated histology, and no reoperation. CONCLUSIONS: This single institution, high-volume experience indicates that pancreaticoduodenectomy can be performed safely for a variety of malignant and benign disorders of the pancreas and periampullary region. Overall survival is determined largely by the pathology within the resection specimen.

RESUMO

OBJECTIVE: This study was designed to evaluate prospectively survival after pancreaticoduodenectomy for pancreatic adenocarcinoma, comparing two different postoperative adjuvant chemoradiation protocol to those of no adjuvant therapy. SUMMARY BACKGROUND DATA: Based on limited data from the Gastrointestinal Tumor Study Group, adjuvant chemoradiation therapy has been recommended after pancreaticoduodenectomy for adenocarcinoma of the head, neck, or uncinate process of the pancrease. However, many patients continue to receive no such therapy. METHODS: From October 1991 through September 1995, all patients with resected, pathologically confirmed adenocarcinoma of the head, neck, or uncinate process of the pancreas were reviewed by a multidisciplinary group (surgery, radiation oncology, medical oncology, and pathology) and were offered three options for postoperative treatment after pancreaticoduodenectomy: 1) standard therapy: external beam radiation therapy to the pancreatic bed (4000-4500 cGy) given with two 3-day fluorouracil (5-FU) courses and followed by weekly bolus 5-FU (500 mg/m2 per day) for 4 months; 2) intensive therapy: external beam radiation therapy to the pancreatic bed (5040-5760 cGy) with prophylactic hepatic irradiation (2340-2700 cGy) given with and followed by infusional 5-FU (200 mg/m2 per day) plus leucovorin (5 mg/m2 per day) for 5 of 7 days for 4 months; or 3) no therapy: no postoperative radiation therapy or chemotherapy. RESULTS: Pancreaticoduodenectomy was performed in 174 patients, with 1 in-hospital death (0.6%). Ninety-nine patients elected standard therapy, 21 elected intensive therapy, and 53 patients declined therapy. The three groups were comparable with respect to race, gender, intraoperative blood loss, tumor differentiation, lymph node status, tumor diameter, and resection margin status. Univariate analyses indicated that tumor diameter < 3 cm, intraoperative blood loss < 700 mL, absence of intraoperative blood transfusions, and use of adjuvant chemoradiation therapy were associated with significantly longer survival (p < 0.05). By Cox proportional hazards survival analysis, the most powerful predictors of outcome were tumor diameter, intraoperative blood loss, status of resection margins, and use of postoperative adjuvant therapy. The use of postoperative adjuvant chemoradiation therapy was a predictor of improved survival (median survival, 19.5 months compared to 13.5 months without therapy; p = 0.003). The intensive therapy group had no survival advantage when compared to that of the standard therapy group (median survival, 17.5 months vs. 21 months, p = not significant). CONCLUSIONS: Adjuvant chemoradiation therapy significantly improves survival after pancreaticoduodenectomy for adenocarcinoma of the head, neck, or uncinate process of the pancreas. Based on these survival data, standard adjuvant chemoradiation therapy appears to be indicated for patients treated by pancreaticoduodenectomy for adenocarcinoma of the head, neck, or uncinate process of the pancreas. Intensive therapy conferred no survival advantage over standard therapy in this analysis.

RESUMO

The clinical effectiveness of flecainide acetate was evaluated in 36 patients (29 male and 7 female, average age 56 years) in whom therapy with previous antiarrhythmic agents had failed. All patients had documented ventricular tachycardia on Holter electrocardiographic recording and 31 of 36 (86%) had had syncope or required cardiopulmonary resuscitation, or both. Angiographic findings demonstrated significant coronary artery disease in 22 (61%) and primary left ventricular dysfunction in 14 (39%), with a left ventricular ejection of 0.39 +/- 0.4. Patients were treated with an average flecainide dose of 302 +/- 76 mg/day. The follow-up time was 101 +/- 156 days. Thirty-two of 36 patients (89%) had complete elimination of ventricular tachycardia from Holter monitoring and only 2 patients had flecainide discontinued because of noncardiac side effects (numbness, blurred vision and ataxia). However, the drug was subsequently discontinued in 5 patients because of cardiac side effects (proarrhythmic effect in 2, sinus bradycardia in 1, complete atrioventricular block in 1 and new left bundle branch block in 1) and 10 patients died during flecainide therapy (1 with cerebral stroke, 3 with congestive heart failure and 6 with incessant ventricular tachycardia). A comparison of the general cardiac features of those who died with those who did not revealed a significantly lower ejection fraction (0.24 +/- 0.1 vs 0.45 +/- 0.1, p less than 0.05) and a significantly higher flecainide dose (350 +/- 85 versus 276 +/- 59 mg/day, p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
