Aim: The aims of this study were to investigate outcomes of abdominal trauma in patients with hemorrhagic shock requiring emergency laparotomy and clarify the beneficial effects of intra-aortic balloon occlusion (IABO) for intra-abdominal hemorrhage in patients with critically uncontrollable hemorrhagic shock (CUHS).Methods: We reviewed 44 hemorrhagic shock patients who underwent emergency laparotomy for intra-abdominal hemorrhage over a 6-year period. Of these patients, we examined data for 19 subjects who underwent IABO during initial resuscitation to control massive intra-abdominal bleeding leading to CUHS. Results:The average Injury Severity Score and probability of survival (Ps) of the 44 patients were 27.6 AE 15.4 and 0.735 AE 0.304, respectively, and the overall survival rate was 77.3%. The differences in the Glasgow Coma Scale, lactate level, prothrombin time -international normalized ratio, and Ps between the two groups (21 responders and 23 non-responders) were statistically significant (P < 0.05). Intra-aortic balloon occlusion was attempted in 19 of 23 patients (82.6%) with CUHS, and there were no statistically significant differences in presenting Glasgow Coma Scale, body temperature, lactate, prothrombin timeinternational normalized ratio, or Revised Trauma Score between the survivors (n = 12) and non-survivors (n = 7). The only significant differences between these two groups were observed in Injury Severity Score (P = 0.047) and Ps (P = 0.007). In all patients, the balloons were successfully placed in 8.1 AE 3.3 min in the thoracic aorta, and a significant increase in systolic blood pressure was observed immediately after IABO. Conclusion:The IABO procedure can be life-saving in the management of patients with CUHS arising from intra-abdominal hemorrhage, permitting transport to surgery.

We report the case of a patient for whom surgical hemostasis of gastrointestinal bleeding due to a splenic artery pseudoaneurysm, which developed due to gastric ulcer penetration, was achieved with resuscitative endovascular balloon occlusion of the aorta without ischemia of organs including the spleen.

Goals: We examined whether synbiotics enhance improvement by probiotics.Background: Probiotics, which are beneficial microbacteria, are a nutritional intervention for treatment of functional constipation or its tendency. Prebiotics, meanwhile, can promote the proliferation of probiotics in the gastrointestinal tract and enhance their beneficial effects. Synbiotics, a combination of probiotics and prebiotics, may be superior to probiotics in the treatment of defecationrelated symptoms, but this requires elucidation.Study: This randomized, double-blind, placebo-controlled study enrolled 69 healthy adults with constipation tendency. Participants were allocated to either control, probiotics, or synbiotics groups and they recorded details of their defecations and their condition. The first 2 weeks were the observation period and the latter 2 weeks were the intervention period, in which participants took test foods. Probiotic foods included Bifidobacterium longum NT strain (10 10 CFU/day), synbiotic foods included the NT strain (10 10 CFU/ day) and galactooligosaccharide (1 g/day). Placebo foods contained the vehicle only. Participants answered questionnaires (Patient Assessment on Constipation Symptoms [PAC-SYM], and one on dietary history) on the last day of each period.Results: Nine participants withdrew consent, and 2 of the remaining 60 had missing data. Age, body mass index, and sex were not significantly different between the 3 groups. Frequency of bowel movements in the fourth week, the primary endpoint, was not increased in the probiotics or synbiotics groups compared with the control group, and the frequency of bowel movements and days with defecation were not changed by probiotics or synbiotics during the intervention period. Probiotics and synbiotics did not improve stool conditions, although incomplete defecation was improved by probiotics but not by synbiotics compared with placebo. PAC-SYM indicated that stool condition and total scores were improved by probiotics but not by synbiotics during the intervention compared with placebo. Conclusion:The probiotic strain Bifidobacterium longum NT can improve constipation symptoms, especially stool condition, but it does not increase bowel movement frequency in healthy adults with constipation tendency. Synbiotics treatment seemed to diminish this improvement of constipation induced by probiotics. This study indicates the possibility of attenuation of beneficial effects from probiotics by the use of synbiotics, contrary to synbiotics theory.
