示例:
parenteral nutrition is being used with increasing frequency as a prima
ry source of caloric support in adult and pediatric patients with gastr
ointestinal problems. numerous complications have been associated with
the administration of tpn, including a significantly increased incidenc
e of gallbladder disease [3-5,7]. the data here suggest that cholecyste
ctomy is often required for the management of symptomatic gallbladder d
isease in this group of patients, and is associated with significant ri
sks.[说明研究背景,包括意义]
of the 35 patients who required cholecystectomy for tpn-induced gallbla
dder disease, operative morbidity and mortality were 54 percent and 11
percent, respectively. maingot [8] has stated that cholecystectomy “is
one of the simplest and safest of the abdominal operations, and is ass
ociated with a low operative mortality rate (about 0.5 percent). a revi
ew of the pediatric literature suggests that when cholecystectomy is pe
rformed in children, the operative morbidity is less than 10 percent, a
nd the mortality is less than 1 percent. [8,9] glenn [11] has reported
a mortality rate of less than 0.1 percent in over 5,000 patients under
the age of 50 years who underwent cholecystectomy. the morbidity and mo
rtality observed in our group of receiving long-term tpn, therefore, we
re far in excess of what would be expected for a population of patients
whose mean age was 29 years. [提出本研究主要发现并将其与其他研究发现相

our data suggest that are specific factors unique to patients who requi
re long-term tpn that contribute to the increased mortality and morbidi
ty associated with cholecystectomy in this select group.[以下,作者用较12

based on the results of our studies, we believe that early cholecystect
omy is indicated in patients with tpn-induced gallbladder disease. obvi
ously, all patients with symptomatic disease should undergo cholecystec
tomy unless there specific medical contraindications. these operations
should be performed in a timely, elective fashion because delay may res
ult in the need for urgent surgery and thereby, increase an already hig
h risk. although recent studies have suggested that cholecystectomy may
not be warranted in otherwise healthy patients with asymptomatic gallb
ladder disease [20], we believe that this axiom does not apply to patie
nts with tpn-induced gallbladder disease. out data suggest that the nat
ural history of gallbladder disease in patients receiving tpn is consid
erably different from that of their counterparts not receiving tpn. bas
ed on our findings, we recommend elective cholecystectomy in patients r
eceiving tpn when gallstones first appear. furthermore, cholecystectomy
should be considered, especially in children without stones who are un
dergoing laparotomy for other reasons. [从对结果的分析及与其他研究的比较
