Effects of Postdischarge High-Protein Oral Nutritional Supplements and Resistance Training in Malnourished Surgical Patients: A Pilot Randomized Controlled Trial.

The presence of malnutrition is increasingly becoming a postdischarge problem in surgical patients. We aimed to investigate whether oral nutritional supplements combined with resistance training could minimize skeletal muscle atrophy in surgical patients after discharge. This randomized controlled study was conducted at the Department of Surgery, National Hospital of Faroe Islands from 2018 to 2020. A total of 45 patients aged 37−74 years participated and were allocated to one of three groups: diet (DI; n = 13), exercise and diet (EX + DI; n = 16), or control (CON; n = 16). The intervention period lasted 8 weeks. The intervention groups received individual dietary counselling and a protein-rich oral nutritional supplement twice a day containing 22 g of protein/day. Patients in the EX + DI group were assigned to resistance training sessions. Patients in the CON group received standard care. The primary outcome was change in lean body mass (LBM). Secondary outcomes were change in body weight, handgrip strength, quality of life, surgery-related side effects, energy and protein intake, length of stay and one-year mortality. To estimate within-group changes, linear mixed models including group−time interactions as fixed effects and patients as random effects were fitted. Within-group change in LBM was 233, 813 and 78 g in the DI, EX + DI and CON groups, respectively, with no significant between-group difference (p > 0.05). Pain score declined more (p = 0.04) in the EX + DI group compared with the CON group. Body weight, handgrip strength, quality of life and surgery-related side effects did not differ between groups. At the end of study, mean cumulative weight change in the DI and EX + DI groups was 0.4% and 1.6%, respectively, whereas the CON group experienced a weight loss of −0.6%. No significant difference in primary outcome between groups was noted. However, our results indicate some benefits from exercise and nutrition for malnourished surgical patients.

[Self-expanding metal stents as palliative treatment of a malign obstruction in the distal part of the ventricle or duodenum]. / Selvekspanderende metalstents ved palliativ behandling af malign obstruktion i distale del af ventriklen eller duodenum.

INTRODUCTION: Self-expanding metal stents (SEMS) have emerged as a simple therapeutic option for the palliation of patients with non-resectable malignant gastric outlet obstruction. We present our results from a three-year period. MATERIALS AND METHODS: Twenty-nine patients with obstruction from tumors in the pancreas (15), bile ducts (3), stomach (9) or transverse colon (2) underwent palliative stenting with a 9-cm-long, 22 mm Wallstent under general anaesthesia. Insertion of the SEMS was done under endoscopic and fluoroscopic control. Biliary stents were implanted prior to or simultaneously with the duodenal stent in eight patients. Seven were covered 6-cm-long, 10 mm Wallstents. Two patients had biliary stents implanted 12 and 262 days, respectively, after the duodenal stent by "rendezvous" technique. RESULTS: The stent deployment was successful in all patients. There were no procedure-related complications, but one patient died of cardiac arrest 12 hours after the operation. Obstruction was relieved in all patients, and an exclusively oral diet was possible for 23 of them. Seven patients with rapid progression of the disease stayed in hospital and died 0-16 days after the procedure. The median length of stay in hospital after the procedure was 2 days (1-32 days), after which the patients stayed at home for 40 days (2-270 days). The overall median survival time was 47 days (median, 0-274 days). There were no late complications (stent migration or perforation), but two patients needed an overlapping stent due to tumor overgrowth. DISCUSSION: Duodenal stents effectively resolve the obstructive symptoms of gastric outlet obstruction. There are few procedure-related complications, and the vast majority of patients can leave hospital and spend the short time left to them at home.
