During the introduction of laparoscopic surgery, the rates of cholecystectomy increased and remained stable at a higher level during the later years of the study. The rate of completed laparoscopic operations increased from 8% in 1992 to 99% in 2011.

BackgroundThe relationship between different lifestyle factors and the risk of needing cholecystectomy for gallstone disease is not clear. This study aimed to assess the association between anthropometric, lifestyle and sociodemographic risk factors and the subsequent risk of requiring cholecystectomy for gallstone disease during long‐term follow‐up in a defined population cohort.MethodsData from a large population‐based cohort study performed from 1995 to 1997 were used (the second Norwegian Nord‐Trøndelag health study, HUNT2). Following HUNT2, from 1998 to 2011, all patients operated on for gallstone disease with cholecystectomy at the two hospitals in the county, Levanger Hospital and Namsos Hospital, were identified. A Cox proportional hazards model was used for multivariable risk analysis.ResultsThe HUNT2 cohort included 65 237 individuals (69·5 per cent response rate), aged 20–99 years. During a median follow‐up of 15·3 (range 0·6–16·4) years, 1162 cholecystectomies were performed. In multivariable analysis, overweight individuals (body mass index (BMI) 25·0–29·9 kg/m2) had a 58 per cent increased risk of cholecystectomy compared with individuals with normal weight (BMI less than 25·0 kg/m2). Obese individuals (BMI 30 kg/m2 or above) had a twofold increased risk. Increasing waist circumference independently increased the risk of cholecystectomy. In women, current hormone replacement therapy (HRT) increased the risk, whereas hard physical activity and higher educational level were associated with reduced risk of cholecystectomy.ConclusionHigh BMI and waist circumference increased the risk of having cholecystectomy for both sexes. In women, the risk was increased by HRT, and decreased by hard physical activity and higher educational level.

ObjectiveThe study aims to examine gastrointestinal symptoms, quality of life and the risk of psychological symptoms after cholecystectomy.DesignThis is a prospective population-based cohort study based on the Nord-Trøndelag Health Study (HUNT) Norway. HUNT is a repeated health survey of the county population and includes a wide range of health-related items. In the present study, all 3 HUNT surveys were included, performed between 1984 and 2008. Selected items were scores on quality of life, the Hospital Anxiety and Depression Scale (HADS) and selected gastrointestinal symptoms. Participants who underwent cholecystectomy for gallstone disease between 1 January 1990 and until 1 year before attending HUNT3 were compared with the remaining non-operated cohort. Associations between cholecystectomy and the postoperative scores and symptoms were assessed by multivariable regression models.ResultsParticipants in HUNT1, HUNT2 and HUNT3 were 77 212 (89.4% of those invited), 65 237 (69.5%) and 50 807 (54.1%), respectively. In the study period, 931 participants were operated with cholecystectomy. Cholecystectomy was associated with an increased risk of diarrhoea and stomach pain postoperatively. In addition, cholecystectomy was associated with an increased risk of nausea postoperatively in men. We found no associations between cholecystectomy and quality of life, symptoms of anxiety and depression, constipation, heartburn, or acid regurgitation following surgery.ConclusionsIn this large population-based cohort study, cholecystectomy was associated with postoperative diarrhoea and stomach pain. Cholecystectomy for gallstone colic was associated with nausea in men. There were no associations between quality of life, symptoms of anxiety and depression, constipation, heartburn, or acid regurgitation.

Minneord | Tidsskrift for Den norske legeforening Eivind Jullumstrø døde 20. desember 2010, bare 36 år gammel. Med ham har et stort og varmt menneske gått bort; en sjeldent flink lege, en god venn og far. Han etterlater seg Cecilie og barna Alexander, August og Cathrine Aurora.Eivind var født 28. januar 1974 og vokste opp på Tjøtta på Helgelandskysten. Han kom til Levanger som femteårsstudent, og vi forsto raskt at han var uvanlig kunnskapsrik og hadde en sjeldent stor interesse for faget. Han hadde i tillegg et fantastisk lag med alle han møtte, enten det var pasienter, pårørende eller personalet. Vi ble glade da han senere valgte Levanger som turnussted og ønsket å utdanne seg videre innen gastrokirurgi. Han arbeidet på Levanger helt til han ble syk sist sommer, de siste to år som konstituert overlege.
