To validate the need for prescribing low-fat diet in the prevention or reduction of dyspeptic symptoms in the postoperative period in patients undergoing laparoscopic cholecystectomy.
We selected 40 patients, free of liver or pancreatic disease, biliary gallstones, gastritis, ulcer, diabetes and dyslipidemia, who were divided into two groups. We conducted dietary anamnesis, identification of dyspepsia before the onset of cholelithiasis and guidance on appropriate postoperatively feeding (normal or low-fat). We used the chi-square test and Pearson correlation for statistical assessment, considering p d" 0.05 as significant.
When comparing the two groups of patients without preoperative dyspepsia, it was observed that in group I seven patients (63.6%) were asymptomatic and in group II, four (66.7%). In group I, four (36.4%) had onset of symptoms and in group II, two (33.3%), p = 0.684. When correlating the two groups with preoperative dyspeptic symptoms, it was observed that there was permanence, appearance or disappearance of symptoms postoperatively, p = 0.114.
There was no significant effect of low-fat diet in the prevention of gastrointestinal symptoms, especially in preoperatively asymptomatic patients. Thus, there is no need of a low-fat diet. So, it is up to the surgeon to evaluate each patient individually and adjust the diet to his/her needs and clinical conditions.
验证在接受腹腔镜胆囊切除术的患者术后预防或减轻消化不良症状时开具低脂饮食的必要性。
我们选取了40例无肝脏或胰腺疾病、胆结石、胃炎、溃疡、糖尿病和血脂异常的患者,将其分为两组。我们进行了饮食问诊,确定胆石症发作前的消化不良情况,并就术后适当饮食(正常或低脂)给予指导。我们使用卡方检验和Pearson相关性进行统计评估,将p≤0.05视为有统计学意义。
比较两组术前无消化不良的患者时,观察到第一组有7例患者(63.6%)无症状,第二组有4例(66.7%)。第一组有4例(36.4%)出现症状,第二组有2例(33.3%),p = 0.684。将两组有术前消化不良症状的患者进行相关性分析时,观察到术后症状有持续、出现或消失的情况,p = 0.114。
低脂饮食对预防胃肠道症状无显著效果,尤其是对术前无症状的患者。因此,无需采用低脂饮食。所以,应由外科医生对每位患者进行个体化评估,并根据其需求和临床状况调整饮食。
