- Background/Aim: A number of patients continue to suffer from chronic abdominal pain of unknown origin, which may also lead to a prolonged use of opioid analgesics. Symptoms of abdominal pain, nausea and vomiting in this patient group resemble the characteristics of the Roux stasis Syndrome. The aim was to elucidate relationships between chronic abdominal pain, Roux limb motor activity and opioid analgesics. Methods: Roux limb high-resolution manometry and ratings of abdominal pain and quality of life were analysed in 15 gastric bypass patients reporting abdominal pain of unknown origin. Effect of acute opiate administration (morphine i.v.) on fasting Roux limb motor activity was assessed in asymptomatic and morphine-naïve gastric bypass patients (n = 9) and compared with an untreated control group (n = 11). Results: In the symptomatic patient group, we found disturbed Roux limb motor patterns in 10 out of 15 examinations, but no signs of Roux stasis syndrome. A high prevalence of prescribed opioid analgesics as well as a high number of reoperations in this group. The worst quality of life and the highest number of pain-killing medications were observed among the patients with distal pacemaker activity in Roux limb. In the morphine-naïve and asymptomatic patients, morphine increased the muscular tone in the Roux limb during phase III-like motor activity. Summary and Conclusions: A majority of the RYGBP patients with chronic abdominal pain had a disturbed Roux limb fasting motility, and there was a high prevalence of prescribed opioid analgesics. In opiate-naïve RYGBP patients, acute morphine intravenously increased the muscular tone of the Roux limb. © 2019, The Author(s).

- Angiotensin II (AngII) elicits smooth muscle contractions via activation of AngII type 1 receptor (AT1R) in the intestinal wall and in sphincter regions in several species. Achalasia is a rare swallowing disorder and is characterized by a loss of the wave-like contraction that forces food through the oesophagus and a failure of the lower oesophageal sphincter to relax during swallowing.Aims and methods:The present study was undertaken to elucidate expression and distribution of a local renin-angiotensin system (RAS) in the muscular layer of distal normal human oesophagus as well as in patients with achalasia using western blot analysis, immunohistochemistry and polymerase chain reaction (PCR).

- Physiological and psychosocial factors might contribute to differences in weight loss, eating behaviour and health-related quality of life (HRQoL) after bariatric surgery. The aim of this study was to investigate how perceived control over eating changes after bariatric surgery and whether it affects outcome in super-obese patients.In a retrospective analysis of a prospective study (n = 60), 49 patients were divided into two groups based on eating control 2 years after surgery, as assessed by the Three-Factor Eating Questionnaire-R21 (TFEQ-R21): 29 with good eating control (GC) and 20 patients with poor eating control (group PC). Eating behaviour and generic and condition-specific HRQoL was assessed by questionnaires.There were significant differences in all TFEQ-R21 domains 2 years after surgery in favour of group GC; uncontrolled eating p < 0.001, emotional eating p < 0.001 and for cognitive restraint p = 0.04. The improvement in HRQoL 2 years after surgery was significantly less in group PC compared to group GC in 7 of 8 SF-36 domains (p < 0.05). Mean (SD) percentage of excess body mass index lost was similar between groups, 71.2 (17.8) in group GC versus 65.4 (17.4) in group PC 2 years after surgery (p = 0.27). However, group GC had a significant weight loss between first and second year after surgery (p < 0.001) compared to group PC (p = 0.15). In super-obese patients, perceived poor control over eating 2 years after bariatric surgery was associated with lower HRQoL and more emotional and cognitive restraint eating, than good control overeating.

- Disasters and major incidents demand a multidisciplinary management. Recent experiences from terrorist attacks worldwide have resulted in a search for better assessment of the needs, resources, and knowledge in the medical and non-medical management of these incidents and also actualized the need for collaboration between civilian and military healthcare. The aim of this study was to evaluate the impact of the civilian-military collaboration in a Swedish context with the main focus on its non-medical management.An exercise, simulating a foreign military attack centrally on Swedish soil, was designed, initiated, and conducted by a team consisting of civilian and military staff. Data were collected prospectively and evaluated by an expert team.Specific practical and technical issues were presented in collaboration between civilian and military staffs. In addition, shortcomings in decision-making, follow-up, communication, and collaboration due to prominent lack of training and exercising the tasks and positions in all managerial levels of the hospital were identified.Current social and political unrests and terror attacks worldwide necessitate civilian-military collaboration. Such collaboration, however, needs to be synchronized and adjusted to avoid preventable medical and non-medical consequences. Simulation exercises might be one important source to improve such collaboration.

- The prevalence of diabetes is increasing worldwide, and most of the cases are type 2 diabetes mellitus. The relationship between type 2 diabetes mellitus and obesity is well established, and surgical treatment is widely used for obese patients with type 2 diabetes mellitus. The aim was to present current knowledge about the possible mechanisms responsible for glucose control after surgical procedures and to review the surgical treatment results.

- Background: Small bowel obstruction due to internal hernia is a common and potentially serious complication after laparoscopic gastric bypass surgery. Whether closure of surgically created mesenteric defects might reduce the incidence is unknown, so we did a large randomised trial to investigate.Method: This study was a multicentre, randomised trial with a two-arm, parallel design done at 12 centres for bariatric surgery in Sweden. Patients planned for laparoscopic gastric bypass surgery at any of the participating centres were off ered inclusion. During the operation, a concealed envelope was opened and the patient was randomly assigned to either closure of mesenteric defects beneath the jejunojejunostomy and at Petersen's space or non-closure. After surgery, assignment was open label. The main outcomes were reoperation for small bowel obstruction and severe postoperative complications. Outcome data and safety were analysed in the intention-to-treat population. This trial is registered with ClinicalTrials. gov, number NCT01137201.Findings: Between May 1, 2010, and Nov 14, 2011, 2507 patients were recruited to the study and randomly assigned to closure of the mesenteric defects (n= 1259) or non-closure (n= 1248). 2503 (99.8%) patients had follow-up for severe postoperative complications at day 30 and 2482 (99.0%) patients had follow-up for reoperation due to small bowel obstruction at 25 months. At 3 years after surgery, the cumulative incidence of reoperation because of small bowel obstruction was signifi cantly reduced in the closure group (cumulative probability 0.055 for closure vs 0.102 for non-closure, hazard ratio 0.56, 95% CI 0.41-0.76, p= 0.0002). Closure of mesenteric defects increased the risk for severe postoperative complications (54 [4.3%] for closure vs 35 [2.8%] for non-closure, odds ratio 1.55, 95% CI 1.01-2.39, p= 0.044), mainly because of kinking of the jejunojejunostomy.Interpretation: The results of our study support the routine closure of the mesenteric defects in laparoscopic gastric bypass surgery. However, closure of the mesenteric defects might be associated with increased risk of early small bowel obstruction caused by kinking of the jejunojejunostomy.
