- Background: There are indications that some features of gastric carcinoma are changing, with a possible impact on prognosis. The aim of this study was to examine any changes in type, location, stage, resection rate, postoperative mortality rate or prognosis for patients with gastric carcinoma in a well defined population. Methods: During 1974-1991, 1161 new cases of gastric adenocarcinoma were diagnosed in Ostergotland County, Sweden. Tumour location, Lauren histological type, tumour node metastasis (TNM) stage, radicality of tumour resection and postoperative complications were recorded after histological re-evaluation of tissue specimens and examination of all patient records. Dates of death were obtained from the Swedish Central Bureau of Statistics. Time trends were studied by comparing the intervals 1974-1982 (period 1) and 1983-1991 (period 2). Results: The proportion of diffuse type of adenocarcinoma increased (from 27 to 35 per cent), while that of mixed type decreased (from 16 to 9 per cent) and that of intestinal type was unchanged. The proportion of tumours located in the proximal two-thirds of the stomach increased (from 32 to 42 per cent) and the proportion of patients with tumours in TNM stage IV decreased (from 32 to 25 per cent). Overall tumour resection rates were unchanged, although the proportion of radical total gastrectomies increased (from 36 to 50 per cent). Excluding tumours of the cardia or gastric remnant after previous ulcer surgery, the 5-year relative survival rate after radical resection increased from 25 to 36 per cent and the postoperative mortality rate decreased for both radical (from 11 to 4 per cent) and palliative (from 18 to 6 per cent) resection. Conclusion: The patterns of tumour histology, location and stage of gastric carcinoma have changed in the authors' region. These changes were paralleled by a significant improvement in survival and postoperative mortality rates.

- Background: Laparoscopic appendectomy (LA) has been associated with a faster recovery and less postoperative pain than the open technique. However, few data are available on the clinical outcome of LA in overweight patients. Methods: A group of 106 patients with a body mass index (BMI) > 26.4, representing the upper quintile of 500 prospectively randomized patients, were included in the study. They were randomized to undergo either laparoscopic or open appendectomy (OA). Operating and anesthesia times, postoperative pain, complications, hospital stay, functional index (1 week postoperatively), sick leave, and time to full recovery were documented. Results: In OA, the operating time for overweight patients was significantly longer than that for patients in the normal weight range (40 vs 35 min, p < 0.05). In LA, there was no difference in operating time between the normal and overweight patients. Overweight patients who underwent LA had longer operating and anesthesia times than their OA counterparts (55 vs 40 min, p < 0.001, and 125 vs 100 min, p < 0.001, respectively). Postoperative pain was significantly greater in overweight patients who underwent OA than in those treated with the laparoscopic technique. Postoperative pain was also significantly greater in overweight patients subjected to OA than in patients of normal weight after 4 weeks, the clinical significance may, however, be of less importance since the values are low (0.26 vs 0.09, p < 0.05). There were no significant differences between the two operating techniques in terms of complications. Hospital stay was longer for overweight patients than for normal-weight patients undergoing OA (3.0 vs 2.0, p < 0.01). The functional index did not differ between any group of patients. Sick leave was longer for overweight patients who underwent OA than for normal-weight patients treated with the same technique (17 vs 13 days, p < 0.01). In the laparoscopic group, however, there were no differences between the overweight and normal-weight patients. Time to full recovery was greater in overweight patients subjected to OA than in the overweight patients in the LA group (22 vs 15 days, p < 0.001). Conclusion: In this study, overweight patients who were submitted to LA had less postoperative pain and a faster postoperative recovery than overweight patients who had OA. LA also abolished some of the negative effects that overweight had on operating time, hospital stay, and sick leave with the open technique. However, anesthesia and operating times were significantly longer in LA for both overweight patients and those with a normal BMI.

Trends and current clinical aspects of complicated gallstone disease - with special reference to endoscopic treatment
- 1993

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Time trends regarding incidence, management, and outcome of acute (AC) and elective cholecystectomy (EC), as well as symptomatic (cholangitis, pancreatitis, jaundice) and asymptomatic (detected accidentally during cholecystectomy) common bile duct (CBD) stones were studied during the time period 1970-1986 in a welldefined Swedish population. From period I (1970-1978) to period II (1979-1986) there was a four-fold increase in the ratio of AC (period I: mean 10/100,000/year, period II: mean 30/100,000/year) to EC (period 1: mean 190/100,000/year, period II: mean 120/100,000/year). For both AC and EC the fraction of patients older than 70 years increased significantly with time. For AC, the female to male ratio decreased significantly from 2.6 to 1.0. The duration of history and frequency of previous hospital stay for gallstone disease decreased significantly for both groups. The postoperative morbidity did not change, whereas the postoperative mortality after AC decreased significantly. Postoperative mortality was significantly higher after AC than EC in both periods. Complications occurred less frequently among patients with a short history of gallstone symptoms than among those with a long history.During the same time periods, there was a significant increase in the incidence of symptomatic CBD stones (8 - 20 cases/100,000 inhabitants/year), and a slight decrease in the incidence of asymptomatic CBD stones (12- 10 cases/lOO cholecystectomies/year). The fraction of patients older than 70 years increased from 31% to 60% for patients with symptomatic CBD stones and from 17% to 27% for patients with asymptomatic CBD stones. In period 11 endoscopic sphincterotomy (EST) accounted for 81 % of all primary procedures performed in patients with symptomatic CBD stones. Type of treatment disregarded, the frequency of clinically overt retained CBD stones increased from 7 % to 22 %. Overall, the frequency of general complications decreased significantly,mainly due to a decrease in the group with symptomatic CBD stones. The frequency of procedure related complications also decreased in the symptomatic group, whereas it increased in the asymptomatic group. Theoverall mortality rate decreased significantly. The total time of stay in hospital decreased by 48 % for patients with symptomatic CBD stones and 23 %for those with asymptomatic stones.EST for retained or recurrent CBD stones after cholecystectomy was performed in 128 patients with an overall success rate of 92 %. Late bile duct complications (recurrent stones and/or stenosis) occurred in seven patients at a median time of 20 months after EST and were best treated with repeat EST. To minimize short-term complications, efforts to extract all stones and confirmation of CBD clearance is mandatory at the initialprocedure. EST is safe and efficient as the first procedure of choice in patients with retained and recurrent CBD stones.EST was performed in 148 patients with CBD stones and the gallbladder left in situ with an overall success rate of 88 %. The median observation time in 118 patients discharged with the gallbladder in situ was 42 months. Complications necessitating acute surgery arose from the remaining gallbladder in seven patients (6 %) at a median of 14 months after EST. Another six patients (5 %) underwent elective cholecystectomy at a median of 21 months after EST. A stone bearing gallbladder left in situ after EST does not appear to be an additional risk factor for future complications compared to the natural history in patients with verified cholelithiasis. Leaving the gallbladder in situ after EST is justified in elderly and frail patients. Surgery should be restricted to patients in whom symptoms develop.The occurrence of bacteremia in association with diagnostic or therapeutic ERCP were studied in 180 patients undergoing 194 examinations, and it occurred in 15 % and 27 %, respectively. There was no correlation between the occurrence of bacteremia and the duration of the procedure. The frequency of complications in patients with bacteremia did not diffef from that in patients without bacteremia, whether the procedure was diagnostic or therapeutic. Routine antibiotic prophylaxis is not indicated in patients undergoing diagnostic or therapeutic ERCP.Extracorporeal shock wave lithotripsy (ESWL) was performed in 28 patients with problematic CBD stones and 9 patients with intrahepatic duct (IHD) stones. The overall fraction of successfully treated patients was 89 %, with no major complications or mortality. It is concluded that ESWL is a safe and efficient treatment modality for CBD and IHD stones after failed endoscopic treatment. It further extends the number of patients with bile duct stones who can be treated by non-surgical means.
