Standardized ileal digestibility of amino acids in soybean meal fed to non-pregnant and pregnant sows

Background Two studies were designed to determine standard ileal crude protein(CP)and amino acid(AA)digestibility of soybean meal(SBM)from different origins fed to non-pregnant and pregnant sows.Seven solvent-extracted SBMs from soybeans produced in the USA,Brazil,and China were selected.In Exp.1,eight different diets were created:a nitrogen(N)-free diet and 7 experimental diets containing SBM from different origins as the only N source.Eight non-pregnant,multiparous sows were arranged in an 8×8 Latin square design(8 periods and 8 diets).In Exp.2,the diet formula was the same as in Exp.1.Eight gestating sows(parity 3)were assigned to 4 different diets in a replicated 4×3 Youden square design(three periods and four diets)in mid-gestation and again in late-gestation stages.Results When fed to non-pregnant and late-gestating sows,the standardized ileal digestibility(SID)of CP and most AAs from different SBM were not significantly different(P>0.05).When fed to mid-gestating sows,the SID values for Arg,His,Lys,Phe,Cys,Gly,Ser,and Tyr in SBM 1 were lower than in SBM 4 and 5(P<0.05),whereas SID for Leu from SBM 5 was higher than in SBM 1 and 4(P<0.05).SID values for Ile,Ala,and Asp from SBM 4 were lower than in SBM 1 and 5(P<0.05).Sows had significantly greater SID values for Lys,Ala,and Asp during mid-gestation when compared with late-gestation stages(P<0.05).Mid-gestating sows had greater SID value for Val and lower SID value for Tyr when compared with non-pregnant and late-gestating sows(P<0.01),whereas non-pregnant sows had significantly greater SID value for Met when compared with gestating sows(P<0.01).Conclusions When fed to mid-gestating sows,the SID values for most AAs varied among SBM samples.The SID values for Lys,Met,Val,Ala,Asp,and Tyr in SBM were affected by sow gestation stages.Our findings provide a cornerstone for accurate SBM use in sow diets.

Oils with different degree of saturation:effects on ileal digestibility of fat and corresponding additivity and bacterial community in growing pigs

Background Oils are important sources of energy in pig diets.The combination of oils with different degree of saturation contributes to improve the utilization efficiency of the mixed oils and may reduce the cost of oil supplemented.An experiment was conducted to evaluate the effects of oils with different degree of saturation on the fat digestibility and corresponding additivity and bacterial community in growing pigs.Methods Eighteen crossbred(Duroc×Landrace×Yorkshire)barrows(initial body weight:29.3±2.8 kg)were surgically fitted with a T-cannula in the distal ileum.The experimental diets included a fat-free basal diet and 5 oil-added diets.The 5 oil-added diets were formulated by adding 6%oil with different ratio of unsaturated to saturated fatty acids(U:S)to the basal diet.The 5 oils were palm oil(U:S=1.2),canola oil(U:S=12.0),and palm oil and canola oil were mixed in different proportions to prepare a combination of U:S of 2.5,3.5 and 4.5,respectively.Results The apparent and standardized ileal digestibility(AID and SID)of fat and fatty acids increased linearly(P<0.05)as the U:S of dietary oils increased except for SID of fat and C18:2.The AID and SID of fat and fatty acids differed among the dietary treatments(P<0.05)except for SID of unsaturated fatty acids(UFA)and C18:2.Fitted one-slope broken-line analyses for the SID of fat,saturated fatty acids(SFA)and UFA indicated that the breakpoint for U:S of oil was 4.14(R^(2)=0.89,P<0.01),2.91(R^(2)=0.98,P<0.01)and 3.84(R^(2)=0.85,P<0.01),respectively.The determined SID of fat,C18:1,C18:2 and UFA in the mixtures was not different from the calculated SID of fat,C18:1,C18:2 and UFA.However,the determined SID of C16:0,C18:0 and SFA in the mixtures were greater than the calculated SID values(P<0.05).The abundance of Romboutsia and Turicibacter in pigs fed diet containing palm oil was greater than that in rapeseed oil treatment group,and the two bacteria were negatively correlated with SID of C16:0,C18:0 and SFA(P<0.05).Conclusions The optimal U:S for improving the utilization efficiency of mixed oil was 4.14.The SID of fat and UFA for palm oil and canola oil were additive in growing pigs,whereas the SID of SFA in the mixture of two oils was greater than the sum of the values of pure oils.Differences in fat digestibility caused by oils differing in degree of saturation has a significant impact on bacterial community in the foregut.

“Keyboard sign”and“coffee bean sign”in the prenatal diagnosis of ileal atresia:A case report

BACKGROUND Ileal atresia is a congenital abnormality where there is significant stenosis or complete absence of a portion of the ileum.The overall diagnostic accuracy of prenatal ultrasound in detecting jejunal and ileal atresia is low.We report a case of ileal atresia diagnosed prenatally by ultrasound examination with the“keyboard sign”and“coffee bean sign”.CASE SUMMARY We report a case of ileal atresia diagnosed in utero at 31 weeks'of gestation.Prenatal ultrasound examination revealed two rows of intestines arranged in an‘S’shape in the middle abdomen.The inner diameters were 1.7 cm and 1.6 cm,respectively.A typical“keyboard sign”was observed.The intestine canal behind the“keyboard sign”showed an irregular strong echo.There was no normal intestinal wall structure,showing a typical“coffee bean sign”.Termination of the pregnancy and autopsy findings confirmed the diagnosis.CONCLUSION The prenatal diagnosis of ileal atresia is difficult.The sonographic features of the“keyboard sign”and“coffee bean sign”are helpful in diagnosing the location of congenital jejunal and ileal atresia.

Five Year Follow up after Surgical Treatment of Type 2 Diabetes with Laparoscopic Sleeve Gastrectomy Associated with a Duodenal Ileal Interposition

Introduction: Type 2 diabetes mellitus (T2D) is a chronic disease, primarily caused by a combination of defective insulin secretion and the inability of insulin-sensitive tissues to respond to insulin. Laparoscopic sleeve gastrectomy associated with duodenal ileal interposition (SGDII) has been shown to be a feasible treatment option for patients with T2D, as it provides improvement and control of glycemia, dyslipidemia and arterial hypertension. The aim of this study was to evaluate the mid and long-term results of SGDII for the treatment of diabetic patients, considering diabetic remission, weight loss and postoperative complications. Materials and Methods: Retrospective study with 96 patients with T2D submitted to SGDII, between 2010 and 2016. The glycated hemoglobin (HbA1c) value Results: Sixty-one patients (62.8%) were male, and 36 patients (37.2%) were female. The average age was 50.9 years. Median BMI was 33.43 kg/m2. The incidence of major postoperative complications in the first 30 days was 2.1%, with no mortality. Dyslipidemia control was sustained, after five years, in 62% of the patients. The five years follow-up demonstrated that 80% of patients had T2D remission at one year, 74.5% at three years and 61.8% at five years. Univariate analysis demonstrated that preoperative values of HbA1c and BMI, preoperative use of insulin, gender, and 30-day complication were not predictors of remission at all study intervals. The average duration of the disease was nine years and the mean glycated hemoglobin before surgery was 8.95%. Conclusion: SGDII resulted in good glycemic control at 5-years follow-up and represents a valid alternative for the treatment of T2D.

Effects of dietary oil sources and fat extraction methods on apparent and standardized ileal digestibility of fat and fatty acids in growing pigs

Background:There is a lack of data for the standardized ileal digestibility(SID) of fat and fatty acids in national feed databases.In addition,it is important to specify the procedures used for fat analyses.Therefore,an experiment was conducted to 1) determine the apparent ileal digestibility(AID) and SID of fat and fatty acids in ten different oil sources for growing pigs and to develop prediction equations for SID of fat based on fatty acid composition;and 2) compare the effect of the fat extraction methods on the calculated values for endogenous loss and digestibility of fat.Methods:Twenty-two barrows(initial body weight:32.1 ± 2.3 kg) were surgically fitted with a T-cannula in the distal ileum,and allotted to 1 of 11 experimental diets in a 4-period Youden Square design.A fat-free diet was formulated using cornstarch,soy protein isolate and sucrose.Ten oil-added diets were formulated by adding 6% of dietary oil sources to the fat-free diet at the expense of cornstarch.All diets contained 26% sugar beet pulp and 0.40% chromic oxide.Results:The endogenous loss of ether extract(EE) was lower than that of acid-hydrolyzed fat(AEE;P < 0.01).There were significant differences in the AID and SID of fat and saturated fatty acids across the dietary oil sources(P < 0.05).The SID of AEE for palm oil was lower than that of sunflower oil,corn oil,canola oil,rice oil and flaxseed oil(P < 0.01).The AID and SID of fat ranged from 79.65% to 86.97% and from 91.14% to 99.18%.Although the AID of EE was greater than that of AEE(P < 0.01),there was no significant difference in SID of EE and AEE except for palm oil.The ratio of unsaturated to saturated fatty acids(U/S) had a positive correlation with SID of fat(P < 0.05),whereas C16:0 and long chain saturated fatty acids(LSFA) were significant negatively correlated with SID of fat(P < 0.01).The best-fit equation to predict SID of fat was SID AEE = 102.75-0.15 × LSFA-0.74 × C18:0-0.03 × C18:1(Adjusted coefficient of determination = 0.88,P < 0.01).Conclusions:When calculating the SID of fat,the EE content of the samples can be analyzed using the direct extraction method,whereas the acid hydrolysis procedure should be used to determine the AID of fat.Fat digestibility of dietary oils was affected by their fatty acid composition,especially by the contents of C16:0,LSFA and U/S.

Contemporary outcomes of patients undergoing robotic-assisted radical cystectomy:A comparative analysis between intracorporeal ileal conduit and neobladder urinary diversions

Objective We aimed to compare perioperative and oncologic outcomes for patients undergoing robotic-assisted radical cystectomy(RARC)with intracorporeal ileal conduit(IC)and neobladder(NB)urinary diversion.Methods Patients undergoing RARC with intracorporeal urinary diversion between January 2017 and January 2022 at the Icahn School of Medicine at Mount Sinai,New York,NY,USA were indexed.Baseline demographics,clinical characteristics,perioperative,and oncologic outcomes were analyzed.Survival was estimated with Kaplan-Meier plots.Results Of 261 patients(206[78.9%]male),190(72.8%)received IC while 71(27.2%)received NB diversion.Median age was greater in the IC group(71[interquartile range,IQR 65-78]years vs.64[IQR 59-67]years,p<0.001)and BMI was 26.6(IQR 23.2-30.4)kg/m^(2).IC group was more likely to have prior abdominal or pelvic radiation(15.8%vs.2.8%,p=0.014).American Association of Anesthesiologists scores were comparable between groups.The IC group had a higher proportion of patients with pathological tumor stage 2(pT2)tumors(34[17.9%]vs.10[14.1%],p=0.008)and pathological node stages pN2-N3(28[14.7%]vs.3[4.2%],p<0.001).The IC group had less median operative time(272[IQR 246-306]min vs.341[IQR 303-378]min,p<0.001)and estimated blood loss(250[150-500]mL vs.325[200-575]mL,p=0.002).Thirty-and 90-day complication rates were 44.4%and 50.2%,respectively,and comparable between groups.Clavien-Dindo grades 3-5 complications occurred in 27(10.3%)and 34(13.0%)patients within 30 and 90 days,respectively,with comparable rates between groups.Median follow-up was 324(IQR 167-552)days,and comparable between groups.Kaplan-Meier estimate for overall survival at 24 months was 89%for the IC cohort and 93%for the NB cohort(hazard ratio 1.23,95%confidence interval 1.05-2.42,p=0.02).Kaplan-Meier estimate for recurrence-free survival at 24 months was 74%for IC and 87%for NB(hazard ratio 1.81,95%confidence interval 0.82-4.04,p=0.10).Conclusion Patients undergoing intracorporeal IC urinary diversion had higher postoperative cancer stage,increased nodal involvement,similar complications outcomes,decreased overall survival,and similar recurrence-free survival compared to patients undergoing RARC with intracorporeal NB urinary diversion.

Right Diaphragmatic Rupture with Passage of an Intrathoracic Ileal Segment Apropos of a Case and Review of the Literature at the Kankan Regional Hospital

Traumatic rupture of the right diaphragmatic dome with herniation of a segment of the hail into the thorax is a rare lesion. It is often the result of a thoraco-abdominal trauma. It can generally lead to early or late cardiopulmonary complications due to compression. The objective of this clinical case is to study the physiopathological mechanisms, the diagnostic and therapeutic modalities of this complication. The diagnosis is often difficult in front of a diaphragmatic rupture since there are no specific clinical signs. In our case, the clinical picture on arrival was that of a high occlusion in an immediate postoperative context. The X-ray which makes it possible to visualize the ascended organs but more difficultly the rupture itself could not be carried out. Treatment is essentially surgical. Although the thoracic approach is preferred by several surgeons because of the difficulties of exposing the diaphragm in the presence of the liver, we chose the abdominal approach instead. The postoperative course is made up of parietal suppuration.

Ileal pouch surgery for ulcerative colitis

Ulcerative colitis (UC) is a relapsing and remitting disease characterised by chronic mucosal and submucosal inflammation of the colon and rectum. Treatment may vary depending upon the extent and severity of inflammation. Broadly speaking medical treatments aim to induce and then maintain remission. Surgery is indicated for inflammatory disease that is refractory to medical treatment or in cases of neoplastic transformation. Approximately 25% of patients with UC ultimately require colectomy. Ileal pouch-anal anastomosis (IPAA) has become the standard of care for patients with ulcerative colitis who ultimately require colectomy. This review will examine indications for IPAA, patient selection, technical aspects of surgery, management of complications and long term outcome following this procedure.

Enteral nutrition combined with glutamine promotes recovery after ileal pouch-anal anastomosis in rats

AIM To assess the effect of enteral nutrition(EN) supplemented with glutamine on recovery after ileal pouch-anal anastomosis(IPAA) in rats, to provide an experimental basis for nutritional support in patients with ulcerative colitis(UC) after IPAA. METHODS Male Sprague-Dawley(SD) rats were randomly divided into three groups(n = 8) after IPAA operation using a microsurgical technique. From the third postoperative day, rats in the control group, EN group, and immune nutrition(IN) group were fed standard rat chow, short peptide EN, and short peptide EN combined with glutamine ad libitum, respectively. The rats' general condition was observed throughout the study. Serum levels of total protein(TP), albumin(ALB), prealbumin(PA), and transferrin(TF) were detected on the 30 th postoperative day, using an automatic biochemical analyzer. The ileal pouch mucosa was stained with hematoxylin and eosin(HE), and occludin protein levels were detected by immunohistochemistry.RESULTS The body weight of rats in the EN group(359.20 ± 10.06 g) was significantly higher than that in the control group(344.00 ± 9.66 g)(P < 0.05) and lower than that in the IN group(373.60 ± 9.86 g)(P < 0.05) on the 30 th postoperative day. The levels of serum TP, ALB, PA, and TF in the EN group were significantly higher than those in the control group(P < 0.01 for all) and lower than those in the IN group(P < 0.05 for all). Histopathological score(EN: 0.80 ± 0.37; IN: 0.60 ± 0.40; control group: 2.29 ± 0.18) and expression level of occludin protein(EN: 0.182 ± 0.054; IN: 0.188 ± 0.048; control group: 0.127 ± 0.032) were significantly lower in the control group compared with the EN and IN groups(P < 0.05 for all), but there were no significant differences between the latter two groups(P > 0.05 for all). CONCLUSION EN combined with glutamine may effectively improve nutritional status after IPAA. Our results suggest a benefit of glutamine supplementation in EN for UC patients undergoing IPAA, although human studies are required to confirm this finding.

Risk of ileal pouch neoplasms in patients with familial adenomatous polyposis

Restorative proctocolectomy is the most common surgical option for patients with familial adenomatous polyposis(FAP). However,adenomas may develop in the ileal pouch mucosa over time,and even carcinoma in the pouch has been reported. We therefore reviewed the prevalence,nature,and treatment of adenomas and carcinoma that develop after proctocolectomy in the ileal pouch mucosa in patients with FAP. In 25 reports that were reviewed,the incidence of adenomas in the ileal pouch varied from 6.7% to 73.9%. Several potential factors that favor the development of pouch polyposis have been investigated,but many remain controversial. Nevertheless,it seems certain that the age of the pouch is important. The risk appears to be 7%to 16% after 5 years,35% to 42% after 10 years,and75% after 15 years. On the other hand,only 21 cases of ileal pouch carcinoma have been recorded in the literature to date. The diagnosis of pouch carcinoma was made between 3 to 20 years(median,10 years) after pouch construction. Although the risk of malignant transformation in ileal pouches is probably low,it is not negligible,and the long-term risk cannot presently be well quantified. Regular endoscopic surveillance,especially using chromoendoscopy,is recommended.

Surgical treatment of ulcerative colitis:Ileorectal vs ileal pouch-anal anastomosis

Total proctocolectomy with ileal pouch-anal anastomosis(IPAA) is the current gold standard in the surgical treatment of ulcerative colitis(UC) refractory to medical management. A procedure of significant magnitude carries its own risks including anastomotic failure, pelvic sepsis and a low rate of neoplastic degeneration overtime. Recent studies have shown that total colectomy with ileorectal anastomosis(IRA) has been associated with good long-term functional results in a selected group of UC patients amenable to undergo a strict surveillance for the relatively high risk of cancer in the rectum. This manuscript will review and compare the most recent literature on IRA and IPAA as it pertains to postoperative morbidity and mortality, failure rates, functional outcomes and cancer risk.

Ileal-anal pouches: A review of its history, indications, and complications

The ileal pouch anal anastomosis(IPAA)has revolutionised the surgical management of ulcerative colitis(UC)and familial adenomatous polyposis(FAP).Despite refinement in surgical technique(s)and patient selection,IPAA can be associated with significant morbidity.As the IPAA celebrated its 40th anniversary in 2018,this review provides a timely outline of its history,indications,and complications.IPAA has undergone significant modification since 1978.For both UC and FAP,IPAA surgery aims to definitively cure disease and prevent malignant degeneration,while providing adequate continence and avoiding a permanent stoma.The majority of patients experience long-term success,but“early”and“late”complications are recognised.Pelvic sepsis is a common early complication with far-reaching consequences of long-term pouch dysfunction,but prompt intervention(either radiological or surgical)reduces the risk of pouch failure.Even in the absence of sepsis,pouch dysfunction is a longterm complication that may have a myriad of causes.Pouchitis is a common cause that remains incompletely understood and difficult to manage at times.10%of patients succumb to the diagnosis of pouch failure,which is traditionally associated with the need for pouch excision.This review provides a timely outline of the history,indications,and complications associated with IPAA.Patient selection remains key,and contraindications exist for this surgery.A structured management plan is vital to the successful management of complications following pouch surgery.

Inhibition of ileal bile acid transporter:An emerging therapeutic strategy for chronic idiopathic constipation

Chronic idiopathic constipation is a common disorder of the gastrointestinal tract that encompasses a wide profile of symptoms. Current treatment options for chronic idiopathic constipation are of limited value; therefore, a novel strategy is necessary with an increased effectiveness and safety. Recently, the inhibition of the ileal bile acid transporter has become a promising target for constipation-associated diseases. Enhanced delivery of bile acids into the colon achieves an accelerated colonic transit, increased stool frequency, and relief of constipationrelated symptoms. This article provides insight into the mechanism of action of ileal bile acid transporter inhibitors and discusses their potential clinical use for pharmacotherapy of constipation in chronic idiopathic constipation.

Restorative proctocolectomy with ileal pouch-anal anastomosis for ulcerative colitis:A narrative review

Restorative proctocolectomy with ileal pouch-anal anastomosis(RP-IPAA) is the gold standard surgical treatment for ulcerative colitis.However,despite the widespread use of RP-IPAA,many aspects of this treatment still remain controversial,such as the approach(open or laparoscopic),number of stages in the surgery,type of pouch,and construction type(hand-sewn or stapled ileal pouch-anal anastomosis).The present narrative review aims to discuss current evidence on the short-,mid-,and long-term results of each of these technical alternatives as well as their benefits and disadvantages.A review of the MEDLINE,EMBASE,and Ovid databases was performed to identify studies published through March 2016.Few large,randomized,controlled studies have been conducted,which limits the conclusions that can be drawn regarding controversial issues.The available data from retrospective studies suggest that laparoscopic surgery has no clear advantages compared with open surgery and that one-stage RP-IPAA may be indicated in selected cases.Regarding 2- and 3-stage RP-IPAA,patients who underwent these surgeries differed significantly with respect to clinical and laboratory variables,making any comparisons extremely difficult.The long-term results regarding the pouch type show that the W- and J-reservoirs do not differ significantly,although the J pouch is generally preferred by surgeons.Hand-sewn and stapled ileal pouch-anal anastomoses have their own advantages,and there is no clear benefit of one technique over the other.

Complications after ileal pouch-anal anastomosis in Korean patients with ulcerative colitis

AIM: To investigate the outcomes of treatments for complications after ileal pouch-anal anastomosis (IPAA) in Korean patients with ulcerative colitis.

Total colorectal and terminal ileal duplication presenting as intussusception and intestinal obstruction

Colonic intussusception and gastrointestinal duplication are diseases that arise in young children. The clinical presentation of adult cases of intussusception and enteric duplication is non-specific and thus poses a diagnostic challenge. A computed tomography (CT) scan is recommended in adult cases as the most sensitive diagnostic tool and the pathognomonic finding of outer intussuscepiens and central intussusceptum is diagnostic. A septum of a duplicated colon in a non-intussuscepted segment has been rarely reported in the literature. With advancements in radiological imaging technology and the increased availability of CT scanners, the capacity for a correct pre-operative diagnosis has been significantly enhanced. Our current case report illustrates the importance of considering an uncommon etiology for enteric intussusception and duplication as a differential diagnosis of acute abdomen in an adult patient. Our analyses of this patient also highlight the successful use of CT scanning to make this diagnosis.

Ileal inflammatory fibroid polyp causing chronic ileocolic intussusception and mimicking cecal carcinoma

Inflammatory fibroid polyp(IFP) is a rare,idiopathic pseudotumorous lesion of the gastrointestinal tract.While mostly reported as solitary gastric lesions,multiple cases of small bowel IFPs are also reported.It is a documented cause of intussusception in adults.In the case reports of ileal inflammatory fibroid polyps with intussusception,an emergent presentation with small bowel obstruction has been most often described.Here we depict a case of ileal inflammatory fibroid polyp presenting with chronic intermittent ileocolic intussusception,anemia and weight loss with an endoscopic appearance mimicking necrotic cecal carcinoma.

Alterations in intestinal microbiota composition coincide with impaired intestinal morphology and dysfunctional ileal immune response in growing-finishing pigs under constant chronic heat stress

Background:Previous studies had shown that short-term acute heat stress(HS)affected the host’s metabolism and intestinal microbiota independent of feed intake(FI)reduction,and long-term calorie restriction caused intestinal morphological injuries and gut microbial alterations.However,research on the effects of constant chronic HS on intestinal microbial composition and the roles of FI reduction played in is limited.This study aimed to investigate the effects of 7-day constant chronic HS on the composition of intestinal microbes in growing-finishing pigs,and its relationship with pigs’performance,intestinal morphology,and ileal immune response.Twenty-four growingfinishing pigs(Duroc×Large White×Landrace,30±1 kg body weight)were randomly assigned to three treatments(n=8),1)thermal neutral(TN)conditions(25±1℃)with ad libitum FI,2)HS conditions(35±1℃)with ad libitum FI,3)pair-fed(PF)with HS under TN conditions to discriminate the confounding effects of dissimilar FI,and the FI was the previous day’s average FI of HS.The small intestinal segments(duodenum,jejunum,and ileum)and feces were collected on d 8.Results:Results indicated that HS drastically declined(P<0.05)average daily gain(ADG)and average daily feed intake(ADFI)(about 61%)in comparison with TN,and caused hyperpyrexia,meanwhile PF caused hypothermia.Morphological observation by light and electron microscopes showed that both HS and PF treatment decreased(P<0.05)the villus and microvillus height compared with TN.Additionally,HS increased(P<0.05)protein expression of heat shock protein 70 in the duodenum,jejunum,and ileum.Furthermore,the expression of tight junction protein zonula occluden-1(ZO-1)in the duodenum and ileum,and Occludin in the ileum were enhanced(P<0.05)compared with TN and PF.Moreover,HS significantly enhanced(P<0.05)the mRNA relative expression of inflammatory cytokines(TLR-2,TLR-4,and tumor necrosis factor-α(TNF-α),IL-6,IL-8,PG1–5,β-defensin 2(pBD-2)),mucins(mucin-1 and mucin-2)and P65 protein level in the ileal mucosa tissue.Intestinal microbiota analysis by 16S rRNA sequencing showed lower(P<0.10)αdiversity in both HS and PF,and a separated cluster ofβdiversity among groups.Compared with TN,HS but not PF mainly reduced(FDR<0.05)Bacteroidetes(phylum),Bacteroidia(class)and elevated the proportions of Proteobacteria(phylum,FDR<0.05),Bacillales(order,FDR<0.05),Planococcaceae(family,FDR<0.05),Kurthia(genus,FDR<0.05),Streptococcaceae(family,FDR<0.10)and Streptococcus(genus,FDR<0.10).Notably,Lactobacillales(order)was decreased(FDR<0.05)by PF alone.Furthermore,the Spearman correlation analysis indicated that the microbes prevalent in HS were positively(P<0.05)associated with intestinal morphological injuries indicators and ileal immune response parameters,and the microbes reduced in HS were negatively(P<0.05)with the performance data.Conclusions:Intestinal morphological injuries and ileal immune response caused by constant chronic HS independent of FI showed close connections with alterations in intestinal microbiota in growing-finishing pigs.

Ileal duplication mimicking intestinal intussusception:A congenital condition rarely reported in adult

Intestinal duplication is an uncommon congenital condition in young adults.A 25-year-old man complained of chronic,intermittent abdominal pain for 3 years following previous appendectomy for the treatment of suspected appendicitis.Abdominal discomfort and pain,suggestive of intestinal obstruction,recurred after operation.A tubular mass was palpable in the right lower quadrant.Computed tomography enterography scan identified suspicious intestinal intussusception,while Tc-99m pertechnetate scintigraphy revealed a cluster of strip-like abnormal radioactivity in the right lower quadrant.On exploratory laparotomy,a tubular-shaped ileal duplication cyst was found arising from the mesenteric margin of the native ileal segment located 15 cm proximal to the ileocecal valve.Ileectomy was performed along with the removal of the duplication disease,and the end-to-end anastomosis was done to restore the gastrointestinal tract continuity.Pathological examination showed ileal duplication with ectopic gastric mucosa.The patient experienced an eventless postoperative recovery and remained asymptomatic within 2 years of postoperative follow-up.

Eviendep~ reduces number and size of duodenal polyps in familial adenomatous polyposis patients with ileal pouchanal anastomosis

AIM:To evaluate if 3 mo oral supplementation with Eviendep was able to reduce the number of duodenal polyps in familial adenomatous polyposis(FAP)patients with ileal pouch-anal anastomosis(IPAA).METHODS:Eleven FAP patients with IPAA and duodenal polyps were enrolled.They underwent upper gastrointestinal(GI)endoscopy at the baseline and after 3 mo of treatment.Each patient received 5 mg Eviendep twice a day,at breakfast and dinner time,for3 mo.Two endoscopists evaluated in a blinded manner the number and size of duodenal polyps.Upper GI endoscopies with biopsies were performed at the baseline(T0)with the assessment of the Spigelman score.Polyps>10 mm were removed during endoscopy and at the end of the procedure a new Spigelman score was determined(T1).The procedure was repeated 3 mo after the baseline(T2).Four photograms were examined for each patient,at T1 and T2.The examined area was divided into 3 segments:duodenal bulb,second and third portion duodenum.Biopsy specimens were taken from all polyps>10 mm and from all suspicious ones,defined by the presence of a central depression,irregular surface,or irregular vascular pattern.Histology was classified according to the updated Vienna criteria.RESULTS:At baseline the mean number of duodenal detected polyps was 27.7 and mean sizes were 15.8mm;the mean Spigelman score was 7.1.After polypectomy the mean number of duodenal detected polyps was 25.7 and mean sizes were 7.6 mm;the mean Spigelman score was 6.4.After 3 mo of Eviendep bid,all patients showed a reduction of number and size of duodenal polyps.The mean number of duodenal polyps was 8(P=0.021)and mean size was 4.4 mm;the mean Spigelman score was 6.6.Interrater agreement was measured.Lesions>1 cm found a very good degree of concordance(kappa 0.851)and a good concordance was as well encountered for smaller lesions(kappa 0.641).CONCLUSION:Our study demonstrated that shortterm(90 d)supplementation with Eviendep in FAP patients with IPAA and with recurrent adenomas in the duodenal mucosa,resulted effective in reducing polyps number of 32%and size of 51%.
