Between 1969 and 1986, 88 patients had a Whipple resection for adenocarcinoma of the pancreas (N = 50), ampulla (N = 19), distal bile duct (N = 10), and duodenum (N = 9). Forty-nine patients were men, 39 were women, and the mean age was 58 years (range: 34-84 years). The patients were divided into two groups on the basis of two different time periods: those operated on from 1969 to 1980 (N = 41) and those operated on from 1981 to 1986 (N = 47). There were no significant differences between the two groups in terms of mean age, sex distribution, duration of symptoms before presentation, or mean weight loss. Likewise, preoperative laboratory data were similar for both groups of patients. In addition, mean tumor size for patients with pancreatic cancer (3.5 cm vs. 3.2 cm) and patients with nonpancreatic periampullary cancer (1.9 cm vs. 2.2 cm) was similar in both groups, as was the incidence of positive lymph nodes. Among the 41 patients operated on during the first period, hospital morbidity and mortality rates were 59% and 24%, respectively. In contrast, hospital morbidity and mortality rates were 36% and 2%, respectively, among the 47 patients operated on during the recent period. During the recent period, more Whipple procedures were performed each year (7.8 vs. 3.4) and by fewer surgeons (3.4 operations/surgeon vs. 1.9 operations/surgeon). In addition, between 1981 and 1986, there were fewer total pancreatectomies (9% vs. 39%), fewer vagotomies (26% vs. 76%), and more pyloric-preserving procedures (30% vs. 0) performed compared with the earlier period. During the recent period, mean operative time (7.8 vs. 9.0 hours), mean estimated blood loss (1694 vs. 3271 mL), and mean intraoperative blood replacement (3.6 vs. 6.3 units) were all significantly less than in the earlier period. These findings suggest that the recent decline in operative morbidity and mortality may be due to fewer surgeons performing more Whipple resections in less time and with less blood loss. The actuarial 5-year survival rate for the 38 patients with nonpancreatic periampullary cancer was 34%. Surprisingly, the actuarial 5-year survival rate among the 50 patients with pancreatic cancer was 18%. Moreover, in the absence of positive lymph node involvement, the 5-year actuarial survival rate among patients with pancreatic cancer was 48%. No explanation is obvious for the improvement in survival among patients with pancreatic cancer.
1969年至1986年间,88例患者因胰腺癌(n = 50)、壶腹癌(n = 19)、远端胆管癌(n = 10)和十二指肠癌(n = 9)接受了惠普尔手术。49例为男性,39例为女性,平均年龄为58岁(范围:34 - 84岁)。根据两个不同时间段,将患者分为两组:1969年至1980年接受手术的患者(n = 41)和1981年至1986年接受手术的患者(n = 47)。两组在平均年龄、性别分布、就诊前症状持续时间或平均体重减轻方面无显著差异。同样,两组患者的术前实验室数据相似。此外,两组中胰腺癌患者(3.5 cm对3.2 cm)和非胰腺壶腹周围癌患者(1.9 cm对2.2 cm)的平均肿瘤大小相似,阳性淋巴结发生率也相似。在第一阶段接受手术的41例患者中,医院发病率和死亡率分别为59%和24%。相比之下,近期接受手术的47例患者中,医院发病率和死亡率分别为36%和2%。在近期,每年进行的惠普尔手术更多(7.8对3.4),而手术医生更少(每位医生3.4例手术对1.9例手术)。此外,与早期相比,1981年至1986年间,全胰切除术更少(9%对39%),迷走神经切断术更少(26%对76%),保留幽门的手术更多(30%对0)。在近期,平均手术时间(7.8对9.0小时)、平均估计失血量(1694对3271 mL)和平均术中输血量(3.6对6.3单位)均显著低于早期。这些发现表明,近期手术发病率和死亡率的下降可能是由于更少的外科医生在更短时间内进行了更多的惠普尔手术,且失血量更少。38例非胰腺壶腹周围癌患者的5年精算生存率为34%。令人惊讶的是,50例胰腺癌患者的5年精算生存率为18%。此外,在无阳性淋巴结受累的情况下,胰腺癌患者的5年精算生存率为48%。目前尚不清楚胰腺癌患者生存率提高的原因。
