RESUMEN
OBJECTIVES: Constipation is the infrequent or difficult emission of hard, dry faeces and is a common digestive condition in cats. Psyllium is a low-fermentable fibre, with soluble and insoluble components and water-holding properties. It forms a mucilaginous gel with water and is used for the symptomatic treatment of constipation in various species. This study evaluated the effect of dietary psyllium on faecal characteristics in cats. METHODS: Healthy neutered adult cats (six female and three male, aged 3.3-4.4 years) were consecutively fed a dry extruded diet containing either 6% psyllium (test) or 6% cellulose (control) for 10 days each. During the last 3 days (the collection days) of both feeding periods, bowel movements and faecal scores were recorded, and faeces were collected to measure wet weight and moisture. The statistical analysis used linear mixed models with diet, day and their interaction as fixed effects and animal as a random term. RESULTS: The test diet was associated with significantly more bowel movements per day over 3 days (P = 0.0052) and on collection day 2 (P = 0.0229) than the control diet. The mean faecal score was higher (softer faeces) over all three collection days (P <0.0001) and on collection days 1, 2 and 3 (P = 0.0011, P = 0.0349, P = 0.0003, respectively) for the test diet vs the control diet; the total faecal wet weight (P = 0.0003) and faecal moisture (%) were also higher (P = 0.0426) for the test diet. Faeces associated with the test diet often had a dry shell and soft interior, which increased the faecal score. CONCLUSIONS AND RELEVANCE: Psyllium promoted more bowel movements and higher faecal moisture and faecal score in healthy cats, consistent with a previous uncontrolled clinical trial in constipated cats. Together, the studies support the use of dietary psyllium for managing cats with constipation.

Constipation is directly related to the intestinal microenvironment, in which the promotion of gastrointestinal (GI) motility and improvement of gut microbiota distribution are important for alleviating symptoms. Herein, after the intervention of probiotic fermented milk (FMMIX) containing Lacticaseibacillus paracasei JY062 and Lactobacillus gasseri JM1 for 14 d in Kunming mice with loperamide-induced constipation, the results indicated that FMMIX significantly increased the secretion of serum motilin, gastrin and 5-hydroxytryptamine, as well as decreased the secretion of peptide YY, vasoactive intestinal peptide, and nitric oxide in mice. As determined by immunohistochemical analysis, FMMIX promoted an augmentation in the quantity of Cajal interstitial cells. In addition, the mRNA and protein expression of c-kit and stem cell factor (SCF) were upregulated to facilitate intestinal motility. High-throughput sequencing and gas chromatography techniques revealed that FMMIX led to an increase in the relative abundance of beneficial bacteria (Lactobacillus, Oscillospira, Ruminococcus, Coprococcus, and Akkermansia), reduced the presence of harmful bacteria (Prevotella), and resulted in elevated levels of short-chain fatty acids (SCFA) with a superior improvement compared with unfermented milk. Untargeted metabolomics revealed significant upregulation of functional metabolites such as l-pipecolinic acid, dl-phenylalanine, and naringenin in FMMIX, presumably playing a potential role in constipation relief. Overall, our results showed that FMMIX had the potential to alleviate constipation symptoms in mice by improving the secretion of serum GI regulatory peptides and neurotransmitters, increasing the expression of c-kit and SCF proteins, and modulating the gut microbiota structure and SCFA levels, and may be associated with an increase in these functional metabolites. This suggested that FMMIX could be a promising adjunctive strategy for managing constipation symptoms and could contribute to the development of functional foods aimed at improving gut health.

In the modern swine industry, inflammation and pain in sows after farrowing represent a crucial animal welfare concern. Cannabis sativa, a medicinal plant, has analgesic, anti-inflammatory and antipyretic properties and is rich in fibre. The objective of this study is to examine the impacts of supplementing sows with Cannabis sativa byproducts during transition periods (7 days before and after farrowing) on various aspects including postpartum behaviour, feed intake, constipation, farrowing duration, colostrum yield and piglet performance. The experiment involved a total of 100 Landrace × Yorkshire sows. The sows were distributed according to parity numbers into two groups, i.e., control (n = 54) and treatment (n = 46). The control group was provided with a lactation diet at 3.0-3.5 kg per day for a period of 7 days before and after farrowing. The treatment groups received the same quantity of the diet but with an additional supplementation of 150 g/d of Cannabis sativa byproduct. The byproduct was analysed and contained 0.24 % (w/w) cannabidiol (CBD), resulting in a daily intake of 360 mg of CBD per sow. The conventional lactational diet had a dietary fibre content of 4.3 %, whereas the diet supplemented with Cannabis sativa byproduct had a higher dietary fibre content of 16.9 %. Video cameras were used to observe and document the behaviour of sows within the initial 24 h after farrowing. The duration in which sows engaged in activities such as sleeping, sitting, standing, feeding and nursing their piglets was quantified. Additionally, the rectal temperature of the sows was measured, and a temperature equal to or exceeding 39.5 °C was considered indicative of fever. The faecal score of the sows was assessed, and a faecal score of ≤2 was classified as constipation. On the third day postpartum, the proportion of sows with fever in the treatment group was lower than that in the control group (20.0 % and 38.9 % respectively, P = 0.051). Sows receiving supplementation with Cannabis sativa byproducts exhibited increased durations of standing and feeding compared to those in the control group (P < 0.05). Notably, overall, sows without constipation issues spent more time consuming feed than those experiencing constipation (P = 0.006). The prevalence of constipation was significantly lower in the treatment group compared to the control group (17.4 % and 81.5 %, respectively, P < 0.001). Furthermore, the postpartum sows demonstrated increased feed intake following supplementation with Cannabis sativa byproducts (P < 0.05). Sow colostrum yield, piglet colostrum intake, piglet mortality and other piglet traits did not differ between the control and treatment groups (P > 0.05). In conclusion, supplementing Cannabis sativa byproducts during the transition periods in peri-parturient sows under tropical conditions resulted in a reduction in constipation issues and improved sow activities, such as increased time spent standing and consuming feed within the first 24 h postpartum.

Constipation and systemic inflammation are common in late pregnant and lactating sows, which cause health problems like uteritis, mastitis, dystocia, or even stillbirth, further influencing piglets' survival and growth. Probiotic supplementation can improve such issues, but the beneficial mechanism of relieving constipation and enhancing gut motility remains underexplored. This study aimed to investigate the effects and mechanism of probiotic supplementation in drinking water to late pregnant sows on constipation, inflammation, and piglets' growth performance. Seventy-four sows were randomly allocated to probiotic (n = 36) and control (n = 38) groups. Probiotic treatment significantly relieved sow constipation, enhanced serum IL-4 and IL-10 levels while reducing serum IL-1ß, IL-12p40, and TNF-α levels, and increased piglet daily gain and weaning weight. Furthermore, probiotic administration reshaped the sow gut bacteriome and phageome structure/diversity, accompanied by increases in some potentially beneficial bacteria. At 113 days of gestation, the probiotic group was enriched in several gut microbial bioactive metabolites, multiple carbohydrate-active enzymes that degrade pectin and starch, fecal butyrate and acetate, and some serum metabolites involved in vitamin and amino acid metabolism. Our integrated correlation network analysis revealed that the alleviation of constipation and inflammation was associated with changes in the sow gut bacteriome, phageome, bioactive metabolic potential, and metabolism.

A 6-year-old, intact female, domestic short-hair cat had a 3-month history of obstipation. On physical examination and diagnostic imaging, megacolon secondary to a large, intrapelvic vaginal mass was diagnosed. An ovariohysterectomy and a complete vaginectomy via a ventral midline celiotomy and bilateral pubic and ischial osteotomies were performed. This approach allowed excellent exposure of the entire genital tract necessary to excise the large vaginal mass. The mass was histologically diagnosed as a vaginal fibrous stromal polyp. Obstipation resolved 12 h after surgery. On radiographic recheck 11 d after surgery, the colon had returned to normal size. No major surgical complications were observed. This is the first case report of a complete vaginectomy via the ventral approach with a pelvic osteotomy in a cat. Furthermore, this report describes the different surgical techniques used in animals affected by a large vaginal mass and provides evidence that an aggressive surgical approach and en-bloc excision can be considered for the management of extensive intrapelvic vaginal masses in cats.
Vaginectomie complète par voie ventrale avec ostéotomie pelvienne chez une chatte. Une chatte domestique à poils courts, intacte, âgée de 6 ans, présentait des antécédents d'obstipation depuis 3 mois. À l'examen physique et à l'imagerie diagnostique, un mégacôlon secondaire à une grosse masse vaginale intra-pelvienne a été diagnostiqué. Une ovario-hystérectomie et une vaginectomie complète via une céliotomie médiane ventrale et des ostéotomies pubiennes et ischiatiques bilatérales ont été réalisées. Cette approche a permis une excellente exposition de l'ensemble du tractus génital nécessaire pour exciser la grosse masse vaginale. La masse a été histologiquement diagnostiquée comme étant un polype stromal fibreux vaginal. L'obstipation a été résolue 12 h après la chirurgie. Lors d'une nouvelle vérification radiographique 11 jours après la chirurgie, le côlon avait retrouvé sa taille normale. Aucune complication chirurgicale majeure n'a été observée. Il s'agit du premier rapport de cas d'une vaginectomie complète par voie ventrale avec ostéotomie pelvienne chez une chatte. En outre, ce rapport décrit les différentes techniques chirurgicales utilisées chez les animaux atteints d'un gros polype vaginal et fournit des preuves qu'une approche chirurgicale agressive et une excision en bloc peuvent être envisagées pour la prise en charge des masses vaginales intra-pelviennes étendues chez les chats.(Traduit par Dr Serge Messier).

OBJECTIVE: To evaluate outcomes in cats undergoing subtotal colectomy for the treatment of idiopathic megacolon and to determine whether removal versus nonremoval of the ileocecocolic junction (ICJ) was associated with differences in outcome. ANIMALS: 166 client-owned cats. PROCEDURES: For this retrospective cohort study, medical records databases of 18 participating veterinary hospitals were searched to identify records of cats with idiopathic megacolon treated by subtotal colectomy from January 2000 to December 2018. Data collection included perioperative and surgical variables, complications, outcome, and owner perception of the procedure. Data were analyzed for associations with outcomes of interest, and Kaplan-Meier survival time analysis was performed. RESULTS: Major perioperative complications occurred in 9.9% (15/151) of cats, and 14% (12/87) of cats died as a direct result of treatment or complications of megacolon. The median survival time was not reached. Cats with (vs without) a body condition score < 4/9 (hazard ratio [HR], 5.97), preexisting heart disease (HR, 3.21), major perioperative complications (HR, 27.8), or long-term postoperative liquid feces (HR, 10.4) had greater hazard of shorter survival time. Constipation recurrence occurred in 32% (24/74) of cats at a median time of 344 days and was not associated with retention versus removal of the ICJ; however, ICJ removal was associated with long-term liquid feces (OR, 3.45), and a fair or poor outcome on owner assessment (OR, 3.6). CONCLUSIONS AND CLINICAL RELEVANCE: Results indicated that subtotal colectomy was associated with long survival times and a high rate of owner satisfaction. Removal of the ICJ was associated with less favorable outcomes in cats of the present study.

Constipation in gestating and lactating sows is common and the inclusion of dietary fiber may help to alleviate this problem. We investigated the effects of inulin (INU) and isomalto-oligosaccharide (IMO), two sources of soluble dietary fiber, on gastrointestinal motility-related hormones, short-chain fatty acids (SCFA), fecal microflora, and reproductive performance in pregnant sows. On day 64 of gestation, 30 sows were randomly divided into three groups and fed as follows: a basal diet, a basal diet with 0.5% INU, and a basal diet with 0.5% IMO. We found that INU and IMO significantly modulated the levels of gastrointestinal motility-related hormones, as evidenced by an increase in substance P (P < 0.05), and a decrease in the vasoactive intestinal peptide concentrations (P < 0.05), indicating the capacity of INU and IMO to alleviate constipation. Furthermore, IMO enhanced the concentrations of acetic, propionic, isobutyric, butyric, isovaleric, and valeric acids in the feces (P < 0.05). High-throughput sequencing showed that IMO and INU increased the fecal microflora α- and ß-diversity (P < 0.05). Methanobrevibacter was more abundant (P < 0.05), whereas the richness of Turicibacter was lower in the INU and IMO groups than in the control group (P < 0.05). In addition, IMO significantly increased litter size (P < 0.05). Overall, our findings indicate that INU and IMO can relieve constipation, optimize intestinal flora, and promote reproductive performance in pregnant sows.

Synbiotic dietary supplements, as an effective means of regulating the gut microbiota, may have a beneficial effect on constipation. This study evaluated the effects of synbiotic yogurt containing konjac mannan oligosaccharides (KMOS) and Bifidobacterium animalis ssp. lactis BB12 (BB12) on constipated Kunming mice (the model group). Following administration of yogurt containing 2.0% KMOS and BB12 (YBK2.0), black fecal weight and number and gastrointestinal transit rate increased by 97.5, 106.3, and 55.7%, respectively, compared with the model group. Serum levels of excitability neurotransmitters (motilin, substance P, and acetylcholine) in the YBK2.0 group were increased by 139.7, 120.4, and 91.8%, respectively, and serum levels of inhibitory neurotransmitters (vasoactive intestinal peptide, nitric oxide, and acetylcholine) were decreased. Moreover, synbiotic yogurt supplementation significantly downregulated the expression of vasoactive intestinal peptide receptor 1 (VIPR1) and upregulated the expression of serotonin receptor 4 (5-HT4) in the colon, and enhanced the expression of the stem cell factor (SCF)/c-Kit pathway. Additionally, YBK2.0 treatment significantly regulated the community composition and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways of gut microbiota, which were positively correlated with physiological parameters of constipation. Thus, supplementation with synbiotic yogurt composed of KMOS and BB12 could facilitate fecal excretion by regulating related pathways and the gut microbiota. These findings demonstrated that the synbiotic yogurt can be considered a functional food for alleviating constipation.

Direct analysis in real time (DART) coupled to high-resolution mass spectrometry (HRMS) was applied for the first time to veterinary forensic toxicology to investigate the presence of toxic compounds in hay after an episode of acute intoxication in a dairy cattle farm. In addition to gross field necropsy and histological examination, microbial cultures, and heavy metals analysis, the molecular fingerprinting of the suspected hay batch was investigated by DART-HRMS. DART-HRMS revealed a distinct signal of m/z 507.2289 in the hay batch thought to be associated with the digestive complications. A search on chemical structure databases matched the ion with asperphenamate, a toxin produced by Penicillium spp. and Aspergillus spp. Liquid Chromatography-HMRS analysis and electrospray-HRMS-MS/MS of the hay extracts further characterized the structure and confirmed the identification of the compound as asperphenamate. Asperphenamate is fungal metabolite which can have cytotoxic and antitumor activity in humans, and it is classified as acute toxicant and harmful if swallowed.

OBJECTIVES: Constipation is a common complaint in cats presenting to the emergency room and can become a frustrating recurrent condition. Despite widespread anecdotal reports of risk factors for constipation, at the time of writing there have been no studies supporting these associations or assessing treatment outcomes. The aim of this study was to identify risk factors in the signalment, history, physical examination and clinicopathologic findings of cats presenting to the emergency room for constipation. In addition, we aimed to assess factors contributing to the success or failure of enemas administered to these cats. METHODS: A medical record search identified 189 cats with a diagnosis of constipation/obstipation that were treated and discharged by the emergency service at an academic veterinary hospital. Data regarding signalment, medical history, physical examination and clinicopathologic findings, as well as treatments performed, were recorded. Ninety-nine cats presenting to the emergency room for other reasons were identified as controls. Statistical analysis was performed to assess risk factors for constipation, as well as success/failure of enema treatments. RESULTS: Older, overweight cats and cats with chronic kidney disease or previous episodes of constipation were found to be at increased risk of constipation (P <0.0001, P = 0.0004, P = 0.0046 and P <0.0001, respectively). Ionized calcium levels were significantly higher in constipated cats, though varied significantly within the cohort (P = 0.0133). Cats noted to be painful on abdominal palpation were less likely to defecate following an enema. Adjunctive treatments (fluids, laxatives) increased the likelihood of a successful enema but were not statistically significant. CONCLUSIONS AND RELEVANCE: Older, overweight cats with a history of constipation or chronic kidney disease are more likely to present for constipation. Further studies are needed to determine the most appropriate treatment protocol in an urgent care setting.

A perineal fluid-filled structure was discovered in a 6-year-old intact female Irish water spaniel suffering from intermittent constipation. Diagnostic tests revealed the structure was immediately caudal to the vagina and compatible with a cyst. Surgical excision was required for resolution of clinical signs. Histology confirmed the structure was a cyst. The exact origin is unknown; however, the variety of lining epithelia, including sections with mucin production, and a well-differentiated smooth muscle layer, were most consistent with development from the lower hindgut or urogenital sinus during embryonic growth. The histologic and anatomical similarities with human retrorectal cystic hamartomas were key in establishing the diagnosis of a perineal cystic hamartoma. Following removal, constipation resolved, and the cyst did not recur.
Hamartome kystique périnéal causant de la constipation chez une femelle intacte de race épagneul d'eau irlandais. Une structure périnéale remplie de liquide fut découverte chez une chienne intacte de race épagneul d'eau irlandais âgée de 6 ans souffrant de constipation intermittente. Les tests diagnostiques ont révélé que la structure était immédiatement caudale au vagin et était compatible avec un kyste. L'excision chirurgicale était requise pour la résolution des signes cliniques. L'histologie confirma que la structure était un kyste. L'origine exacte est inconnue; toutefois, la diversité de l'épithélium de couverture, incluant des sections avec production de mucine, et une couche bien différenciée de muscle lisse, étaient plus cohérentes avec un développement à partir du tractus digestif postérieur ou du sinus urogénital lors de la croissance embryonnaire. Les similarités histologique et anatomique avec l'hamartome rétro-rectal humain étaient critiques pour établir le diagnostic d'hamartome kystique périnéal. À la suite du retrait, la constipation s'est résolue, et il n'y a pas eu de récurrence du kyste.(Traduit par Dr Serge Messier).

OBJECTIVE: To investigate the pharmacological profile and side effects of buprenorphine administered as a sustained-release formulation in horses. STUDY DESIGN: Pilot trial. ANIMALS: A total of four experimental horses, aged 18-27 years and weighing 508-578 kg. METHODS: Buprenorphine (0.1 mg kg-1) was mixed as a freshly prepared sterile solution with a sustained-release drug carrier. It was administered by the subcutaneous (n = 2) or intramuscular (n = 2) route. During the experiment, the horses were closely monitored, equipped with a step counter and blood samples were collected for quantification of buprenorphine in plasma. RESULTS: All four horses developed colon constipation requiring medical therapy, together with increased locomotor activity. One horse, requiring surgical treatment of colon constipation, was euthanized during recovery from anaesthesia for weakness and severe lower airway obstruction. The three other horses recovered fully within 5-7 days. Plasma buprenorphine concentrations were between 1 and 8 ng mL-1 for approximately 48 hours. No local reaction was observed at the injection sites. CONCLUSIONS AND CLINICAL RELEVANCE: Administration of the sustained-release formulation of buprenorphine at a dose of 0.1 mg kg-1 resulted in plasma concentrations compatible with antinociceptive activity for at least 48 hours. The observed severe and undesirable effects of colon constipation and increased locomotor activity definitely preclude clinical use of sustained-release buprenorphine at this dose.

Chronic constipation (CC) and idiopathic megacolon (IMC) occur frequently in cats. The aim of the study was to investigate the effects of a multi-strain probiotic (SLAB51™) in constipated cats (n=7) and in patients with megacolon and constipation (n=3). Ten pet cats with a diagnosis of chronic constipation, non-responsive to medical management received orally 2×1011 bacteria daily for 90 days. For microbiota analysis, selected bacterial groups were analysed by qPCR. Histological samples in megacolons were evaluated for interstitial cells of Cajal (ICC), enteric neurons, and neuronal apoptosis. Biopsies were compared at baseline (T0) and after the end of treatment (T1), and with those obtained from healthy control tissues (archived material from five healthy cats). Constipated cats displayed significantly lower ICC, and cats with idiopathic megacolon had significantly more apoptotic enteric neurons than controls. After treatment with SLAB51™, significant decreases were observed for feline chronic enteropathy activity index (FCEAI) (P=0.006), faecal consistency score, and mucosal histology scores (P<0.001). In contrast, a significant increase of ICC was observed after probiotic therapy. Lactobacillus spp. and Bacteroidetes were increased significantly after treatment (comparing constipated cats before and after treatment, and control healthy cats to constipated cats after treatment), but no other differences in microbiota were found between healthy controls and constipated cats. Treatment with SLAB51™ in cats with chronic constipation and idiopathic megacolon showed significant clinical improvement after treatment, and histological parameters suggest a potential anti-inflammatory effect of SLAB51™, associated with a reduction of mucosal infiltration, and restoration of the number of interstitial cells of Cajal.

Multiple pelvic fractures can lead to narrowing of the pelvic canal and loss of life quality. Hemipelvectomy, characterized by removal of bone fragments from the pelvis, is considered a rescue therapy. This report describes the technique of caudal partial hemipelvectomy in four cases of obstipation secondary to traumatic pelvic canal narrowing in four dogs, with promising results. All patients had tenesmus and fecal retention. After the procedure, the patients presented immediate normochezia and support of the ipsilateral limb after 10 to 20 days, showing the feasibility of the technique in small animals, providing clinical improvement without walking alterations.(AU)

Objectives The aim of the study was to evaluate the management and long-term outcome of cats with pelvic fractures. Methods Cats with pelvic fractures had their records and radiographs reviewed. Radiographs were reviewed for fracture configuration, implants and pelvic canal narrowing. Owners were contacted for long-term follow-up. Results Forty-three cats met the criteria (mean follow-up 24 months [range 6-45 months]). The majority (93%) had more than one orthopaedic pelvic injury, with sacroiliac fracture luxations seen most commonly; 23% had presurgical neurological deficits. Most cats (74%) were managed surgically; 60% of sacroiliac fracture luxations, 82% of ilial fractures and 50% of acetabular fractures received surgery. The complication rate was 22%, most commonly sciatic neurapraxia (13%). Seventy-nine percent of all neurological deficits resolved and the remainder improved. Mean pelvic canal narrowing after trauma was -15% in surgical and -16% in conservatively managed cats. Canal width was improved postoperatively (-8%) but mildly narrowed further by follow-up (-12%); however, these changes were not significant. Nineteen percent of cats had constipation postsurgery; none developed megacolon. There was no clear correlation between the degree of narrowing of the pelvic canal up to -50%, or whether conservative treatment was opted for, and the development of constipation. Long-term mobility was not impaired in 86% of cats, and 84% did not have any lameness detectable. Conclusions and relevance The majority of cats were managed surgically, with a 22% complication rate; the most common being transient sciatic neurapraxia. Long-term outcome was generally excellent and most had a full recovery. Constipation/obstipation was very uncommon and no clear relationship with pelvic canal narrowing could be found when considering narrowing of up to -50% in both surgical and conservative groups. As no cats in this cohort had narrowing greater than -50%, the current recommendation of surgery to improve the canal width if narrowing is greater than -45% to -50% should remain.

Objectives The aim of the study was to describe faecal consistency, prevalence and risk factors for diarrhoea and constipation in a rescue cat population. Methods Faecal samples in litter trays from a stratified random sample of cats in pens at 25 UK rehoming centres were scored for consistency in two discrete time periods, summer and winter. A six-point scale was used, with diarrhoea ⩽3, severe diarrhoea ⩽2 and constipation as 6. The effect on faecal consistency of age, number of cats per pen and season was investigated using multivariable hierarchical logistic regression with centre and pen as random effects. Intraclass correlation coefficients were used to estimate the effect of pen and centre. Results Overall, 11.9% (95% confidence interval [CI]:10.4-13.7) of cats had diarrhoea, 2.4% (95% CI 1.6-3.7) had severe diarrhoea and 5.6% (95% CI 4.2-7.5) were constipated. The prevalence of diarrhoea (median 11.0%, interquartile range [IQR] 5.0-14.5%) and constipation (median 4.2%, IQR 1.8-5.9) varied at the centre level. Diarrhoea was associated with being a kitten (odds ratio [OR] 2.54, 95% CI 1.45-4.46; P = 0.001) and being in a multi-cat pen (OR 1.24, 95% CI 1.04-1.48; P = 0.02) but not with season (OR 0.99, 95% CI 0.55-1.77; P = 0.96). Severe diarrhoea was associated with senior cats (OR 4.66, 95% CI 1.25-17.44; P = 0.02). Constipation was associated with increasing age (OR 1.01; 95% CI 1.00-1.01; P = 0.02) and winter (OR 0.43, 95% CI 0.21-0.89; P = 0.02). Both diarrhoea and constipation showed moderate correlation with pens within a centre. Conclusions and relevance From IQRs, we suggest acceptable levels for diarrhoea and constipation of 11% and 4%, respectively, targets of 5% and 2%, and intervention at 15% and 6%. Increasing age was associated with decreased risk of diarrhoea and increased risk of constipation. However, severe diarrhoea was associated with being a senior cat. Season (winter) was a risk factor for constipation; multi-cat pens were a risk factor for diarrhoea. Describing the prevalence and risk factors for diarrhoea and constipation in cats will assist their management in this population. Understanding and managing constipation may be more important than interventions to reduce severe diarrhoea.

Pelvic fractures are a common injury in cats, and both surgical and conservative management approaches have been described. One of the major complications of pelvic fractures managed conservatively is narrowing of the pelvic canal. Severe pelvic canal narrowing can result in constipation and subsequent megacolon. The purpose of this case series is to describe the long-term outcome for 3 cats with obstipation treated with internal hemipelvectomy because of megacolon secondary to pelvic canal narrowing after conservative management. All cats had a good functional outcome of the affected limb. Two cats required ongoing medical management for recurrent constipation. Overall, internal hemipelvectomy offers good long-term limb function; however, its success in relieving clinical signs of constipation requires additional research.
Hémipelvectomie interne pour le traitement de la constipation opiniâtre secondaire à un cal vicieux pelvien chez 3 chats. Les fractures pelviennes sont une blessure commune chez les chats et les approches chirurgicales et prudentes ont toutes deux été décrites. L'une des complications majeures des fractures pelviennes gérées de manière prudente consiste à raccourcir le canal pelvien. Un rétrécissement sévère du canal pelvien peut se traduire par la constipation et un mégacôlon subséquent. Le but de cette série de cas consiste à décrire le résultat à long terme pour 3 chats souffrant de constipation opiniâtre traitée par une hémipelvectomie interne en raison d'un mégacôlon secondaire au rétrécissement du canal pelvien après une gestion prudente. Tous les chats ont obtenu de bons résultats fonctionnels du membre affecté. Deux chats ont nécessité une gestion médicale permanente pour une constipation opiniâtre. En général, l'hémipelvectomie interne offre une bonne fonction du membre, mais son succès dans le soulagement des signes cliniques de la constipation exige de la recherche additionnelle.(Traduit par Isabelle Vallières).

Dysregulation of normal kidney functions in chronic kidney disease (CKD) leads to several pathophysiologic abnormalities that have the potential to significantly clinically affect the CKD patient. This article discusses the clinical impact of hypertension, hypokalemia, anemia, dysrexia, nausea/vomiting, and constipation in the CKD patient and therapies for these conditions. These clinical manifestations of disease may not occur in every patient and may also develop later during the progression of disease. Therefore, monitoring for, identifying, and addressing these factors is considered an important part of the medical management of CKD.

OBJECTIVES: Colonic electrical stimulation (CES) may have a therapeutic potential for slow transit constipation (STC). This study aimed to evaluate the effects of implantable CES on gastrointestinal transit and defecation, and explore its mechanisms in a canine STC model. METHODS: Two pairs of electrodes were implanted in each of the proximal colon and rectosigmoid junction (RSJ). Parameters were individualized according to the symptoms of the stimulated dogs. In the STC model, gastrointestinal transit and defecation were assessed to evaluate the effects of double-site CES, and of double-site CES combined with atropine or N-nitro-L-arginine (L-NNA) in a crossover design. RESULTS: Individualized parameters varied among the animals. The CES significantly shortened gastrointestinal transit time (GITT) and colonic transit time (CTT) compared with sham CES (p = 0.001 and p < 0.001, respectively). Compared with sham CES, the CES also exhibited significantly higher stool frequency and stool consistency score (p = 0.018 and p = 0.001, respectively). Co-treatment with atropine or L-NNA blocked the effects of CES on GITT, CTT, and stool consistency. The stool frequency increased by CES, however, only reduced by co-treatment with L-NNA. CONCLUSIONS: This double-site implantable CES can improve the gastrointestinal transit and defecation in a canine STC model, possibly by activating the cholinergic and nitrergic pathways. The CES mode used in this study may be proven feasible in treating STC.

The present study aimed to investigate the prevalence of constipation and its influence on farrowing duration and the evidence of post-parturient disorders in tropical sows and to evaluate the efficacy of a laxative supplementation during gestation and around farrowing on the incidence of constipation. Two experiments were performed in a commercial swine herd in Thailand. In experiment 1, the prevalence of constipation was determined in 96 gestating sows. Subsequently, 62 of them (64.6 %), with a severe to moderate degree of constipation, received 20 ml of a laxative for 3 days during gestation. In experiment 2, constipation score was determined in sows before, during, and after farrowing. A total of 98 sows were randomly allocated to one of two groups: the treatment group (n = 48) received 20 ml of a laxative for 3 days before farrowing, and the control group (n = 50) did not receive any laxative. Rectal temperature, appetite score, incidence of postpartum dysgalactia syndrome (PDS), and vaginal discharge score was determined for 4 days. In experiment 1, supplementation of laxative reduced the proportion of sows with moderate to severe constipation (P < 0.05). In experiment 2, sows with moderate to very severe constipation had a 28-min longer duration of farrowing than sows with normal faeces. Constipation in sows on the day of farrowing resulted in reduced appetite on day 1 postpartum (P = 0.008). The incidence of sows with fever on day 1 postpartum was two times higher in sows with constipation than in sows with normal faeces (36.2 and 16.7 %, respectively; P = 0.041).
