Mini-Mental State Examination predicts mortality in patients on chronic hemodialysis.

BACKGROUND: No available and easy to administer cognitive test has been evaluated for the prediction of mortality in prevalent patients on chronic hemodialysis. The aim of the present study was to determine if the Mini-Mental State Examination (MMSE) was predictor of mortality in patients on chronic hemodialysis. METHODS: One hundred twenty-seven prevalent patients on chronic hemodialysis were studied. All patients underwent assessment of cognitive function through the MMSE. The MMSE was administered during a midweek hemodialysis session, avoiding the beginning and the end of each treatment to minimize the effects of fluctuations in uremic syndrome or blood pressure in accordance with a previous study. An MMSE score ≤23 was used as indicative of cognitive impairment. Demographic, clinical, and laboratory parameters were recorded for each patient. RESULTS: Mean (SD) MMSE was 23.2 ± 4.1. Median MMSE was 24 (min-max: 2-30). MMSE was ≤23 in 72 patients and >23 in 55. With data updated in March 2021, after a mean follow-up of 58.8 ± 41 months (range: 2-156 months), 75 patients died, and 17 were transplanted. None was lost to follow-up or was transferred to another unit. Dead participants, as compared with alive ones, were significantly older, had a higher Charlson Index score, had lower Activities daily living and Instrumental activities daily living, and had a lower MMSE score and lower serum albumin levels. Kaplan-Meier analysis showed that survival was significantly lower in patients with MMSE ≤23 than in those with MMSE >23 (log-rank χ2 : 8.825, p = 0.003). According to Cox regression analysis, mortality was associated with age and inversely associated with MMSE. CONCLUSION: We show that the MMSE predicts mortality in prevalent patients on chronic hemodialysis.

Empirical measurement of pressure in negative pressure wound therapy for infected wounds: How long can it really stay under pressure?

Surgical site infections represent one of the most common surgical complications. Negative pressure wound therapy is considered an effective wound management system, based on the principle that a negative pressure inside the wound can suction fluids and approximate wound edges. With the negative pressure wound therapy systems commercially available it is assumed that the pressure inside the wound is stable at the set values. We conducted a prospective experimental study to investigate this. The negative pressure level achieved inside the dressing was investigated at a standard distance from the pad of suction and at specific times in patients with surgical site infections. Pressure measurements were performed in 28 dressings in 14 patients admitted to the Emergency Surgery Department between April 2016 and June 2017. In general, the machine was set at a pressure of -100 mmHg. Negative pressure was measured with a portable pressure reader in the dressing sponge at a distance of 0, 1.5, and 3 cm from the suction pad at the time of dressing change at 24 and 48 hours. The data suggest that there is a significant decrease in negative pressure at both 1.5 and 3 cm from the suction pad at 48 hours from the dressing change (p = 0.0001 and p < 0.0001, respectively). This preliminary study shows with statistical significance that the pressure inside the sponge of a negative pressure wound therapy system decreases after 48 hours, confirming that the pressure inside the system is not the same as the pressure reported by the machine and, instead of being stable, changes overtime.

The Frustrating Attempt to Limit the Interdialytic Weight Gain in Patients on Chronic Hemodialysis: New Insights Into an Old Problem.

A significant percentage of patients on chronic hemodialysis have an interdialytic weight gain (IDWG) above the recommended values. High IDWG has detrimental effects on survival, cardiovascular outcomes, and quality of life. High IDWG is secondary to poor adherence to fluid restriction and to excessive intake of fluids, due to thirst and xerostomia. Various strategies have been proposed to limit IDWG such as the reduction of dietary salt intake, behavioral interventions aimed at improving the adherence to fluid restriction, the improvement of xerostomia, and the use of lower dialysate sodium concentration. The present narrative review aims to evaluate the efficacy of each of such strategies.

Health-related quality of life of patients on chronic dialysis: The need for a focused effort.

Health-related quality of life (HRQOL) in patients on chronic hemodialysis has not improved significantly in the last 20 years. This is largely due to their substantial symptom burden which is rarely assessed and treated in routine clinical practice. It also is a consequence of the lack of an appropriate armamentarium for the treatments of such symptoms. Adequate studies on the causes and pathogenesis of the symptoms of hemodialysis patients are needed followed by high quality studies on possible therapeutic pharmacological and nonpharmacological interventions.

Fatigue in kidney transplant recipients.

Fatigue is still present in approximately 40%-50% of kidney transplant recipients (KTR), rates comparable to that of the hemodialysis population. Correlates of fatigue include inflammation, symptoms of depression, sleep disorders, and obesity. Fatigue in KTR determines a significant severe functional impairment, either when globally considered or when analyzed at the level of the single domains such as sleep and rest, homemaking, mobility, social interaction, ambulation, leisure activities, alertness behavior, and work limitations. In addition, fatigue in KTR is significantly associated with a severe deterioration of quality of life. Fatigue is very common among KTR poorly adherent to immunosuppressive therapy. Unfortunately, there is no evidence of studies about the treatments of this symptom in KTR. Efforts to detect and treat fatigue should be a priority in order to improve quality of life of KTR.

Serum Endotoxin Activity Measured with Endotoxin Activity Assay Is Associated with Serum Interleukin-6 Levels in Patients on Chronic Hemodialysis.

BACKGROUND: This study aims to evaluate, in patients on chronic hemodialysis (PHD), the levels of endotoxin through a chemiluminescent bioassay based on the oxidative burst reaction of activated neutrophils to complement coated LPS-IgM immune complexes and define the variables possibly correlated. METHODS: In 61 PHD, we measured serum endotoxin activity (EA) with the Endotoxin Activity Assay (EAA™) and we defined the possible association with demographic, clinical and laboratory variables. RESULTS: Mean serum EA was 0.43 ± 0.26 UI. EA was low (<0.40) in 29 patients (47.5%), intermediate (0.40-0.60) in 14 (23%) and high (>0.60) in 18 (29.5%). A significant exponential relationship was detected between EA and serum interleukin-6 (IL-6) levels (r = 0.871). At the multiple regression analysis, intermediate-high EA was directly associated only with serum IL-6 levels. In a second model of multiple regression analysis without the variable serum IL-6 levels, intermediate-high EA was directly associated with constipation and serum troponin levels and inversely associated with serum albumin and the monthly number of sevelamer tablets. CONCLUSIONS: A high percentage of PHD has intermediate or high EA. Intermediate-high EA is significantly associated with serum IL-6 levels.

Functional impairment is associated with an increased risk of mortality in patients on chronic hemodialysis.

BACKGROUND: Functional impairment is associated with adverse outcomes in older people, as well as in patients on chronic hemodialysis. The aim of the present study was to determine the characteristics associated with functional impairment in chronic hemodialysis, and to evaluate if functional impairment represents a risk factor for reduced survival in chronic hemodialysis. METHODS: All 132 chronic hemodialysis referring to the Hemodialysis Service of the Catholic University, Rome, Italy between November 2007 and May 2015 were included. All patients underwent comprehensive geriatric assessment; functional ability was estimated using two questionnaires exploring independency in bathing, dressing, toileting, transferring, continence, feeding (ADLs), and independency in using the telephone, shopping, food preparation, housekeeping, laundering, traveling, taking medications, and handling finances (IADLs). Functional impairment was diagnosed in presence of dependence in one or more ADLs/IADLs. Mood was assessed using the 30-item Geriatric Depression Scale. Logistic regression was used to evaluate factors associated with functional impairment. The association between functional impairment and survival was assessed by Cox regression. RESULTS: ADLs impairment was present in 34 (26 %) participants, while IADLs impairment was detected in 64 (48 %) subjects. After a follow up of 90 months, 55 (42 %) patients died. In logistic regression, depressive symptoms were associated with ADLs and IADLs impairment (OR 1.12; 95 % CI = 1.02-1.23; OR 1.16; 95 % CI = 1.02-1.33; respectively). In Cox regression, ADLs impairment was associated with mortality (HR 2.47; 95 % CI-1.07-5.67) while IADLs impairment was not associated with reduced survival (HR .80; 95 % CI-.36-1.76). CONCLUSIONS: Functional impairment is associated with depressive symptoms; also, impairment in the ADLs represents a risk factor of reduced survival in chronic hemodialysis. These associations and their potential implication should be assessed in dedicated studies.

Interdialytic weight gain and low-salt diet in patients on chronic hemodialysis: A systematic review and meta-analysis.

OBJECTIVE: The present systematic review and meta-analysis aims to determine the difference in the interdialytic weight gain (IDWG) between low salt intake diet and normal/high salt intake diet or between nutritional counseling aimed at reducing diet salt intake and no nutritional counseling in patients on chronic hemodialysis. METHODS: Medline, PubMed, Web of Science, and the Cochrane Library were searched. Randomized, crossover or parallel studies and observational studies were considered for inclusion and: 1) included adult patients on chronic hemodialysis since at least 6 months; 2) compared normal salt intake diet with low salt intake diet on IDWG; 3) compared nutritional counseling aimed at reducing diet salt intake with no intervention on IDWG; 4) reported on IDWG. RESULTS: Eight articles (783 patients) were fully assessed for eligibility and included in the investigation. Meta-analysis showed frequencies of patients that increased their weight after dialysis more than 2.5 Kg (events) over total enrolled subjects for each group (control and experimental). As no significant heterogeneity was observed (I2 = 8%; p = 0.36), the pooled analysis was performed using a fixed-effect model. Funnel plot was generated and no obvious asymmetry was observed. The Overall Odds Ratio to get an event in the experimental group, in respect to controls, is 0.57 (0.33-0.97) (p = 0.04] with single studies OR ranging between 0.11 and 1.08. CONCLUSION: The present systematic review and meta-analysis suggest that the use of a low salt diet sodium or a nutritional counseling aimed at reducing diet salt intake is associated with a statistically significant reduction of the IDWG in patients on chronic hemodialysis.

Interdialytic weight gain and low dialysate sodium concentration in patients on chronic hemodialysis: a systematic review and meta-analysis.

PURPOSE: The present systematic review and meta-analysis aimed at evaluating the effect of low dialysate sodium concentration on interdialytic weight gain (IDWG) in chronic hemodialysis patients. METHODS: Studies were eligible for inclusion if they were English language papers published in a peer-reviewed journal and met the following inclusion criteria: (1) studies in adult patients (over 18 years of age), (2) included patients on chronic hemodialysis since at least 6 months; (3) compared standard (138-140 mmol/l) or high (> 140 mmol/l) dialysate sodium concentration with low (< 138 mmol/l) dialysate sodium concentration; (4) Included one outcome of interest: interdialytic weight gain. Medline, PubMed, Web of Science, and the Cochrane Library were searched for the quality of reporting for each study was performed using the Quality Assessment Tool of Controlled Intervention Studies of the National Institutes of Health. The quality of reporting of each cross-over study was performed using the Revised Cochrane Risk of Bias (RoB) tool for cross-over trials as proposed by Ding et al. RESULTS: Nineteen studies (710 patients) were included in the analysis: 15 were cross-over and 4 parallel randomized controlled studies. In cross-over studies, pooled analysis revealed that dialysate sodium concentration reduced IDWG with a pooled MD of - 0.40 kg (95% CI - 0.50 to - 0.30; p < 0.001). The systematic review of four parallel, randomized, studies revealed that the use of a low dialysate sodium concentration was associated with a significant reduction of the IDWG in two studies, sustained and almost significant (p = 0.05) reduction in one study, and not significant reduction in one study. CONCLUSION: Low dialysate sodium concentration reduces the IDWG in prevalent patients on chronic hemodialysis.

Selective Serotonin Reuptake Inhibitors and Symptoms of Depression in Patients on Chronic Hemodialysis: A Systematic Review.

Objective: The use of selective serotonin reuptake inhibitors (SSRIs) is common among hemodialysis patients who receive treatment for depression. However, studies on the efficacy of SSRIs in patients on chronic hemodialysis are few and have led to conflicting results. The present systematic review aims to evaluate, in randomized, controlled studies (RCSs), the efficacy of SSRI administration in reducing symptoms of depression in patients on chronic hemodialysis when compared with placebo or psychological interventions. Method: Research was run on December 2023 in the following databases: Ovid MEDLINE (1985 to present); Ovid EMBASE (1985 to present); Cochrane Library (Wiley); and PubMed (1985 to present). The primary outcome was the frequency and severity of the symptoms of depression assessed through the Beck Depression Inventory (BDI) or the Hamilton Depression Rating Scale (HAMD). The secondary outcome was the prevalence of adverse events. Results: Seven studies totaling 433 patients were included. The number of patients in each individual study ranged from 13 to 120. The length of studies ranged from 8 weeks to 6 months. Heterogeneous data precluded informative meta-analysis. Three studies compared sertraline with a placebo. Of these, two demonstrated that sertraline was better than the placebo in reducing the symptoms of depression while one showed no statistically significant differences between sertraline and the placebo. One study, comparing fluoxetine with a placebo showed that the symptoms of depression did not differ significantly at 8 weeks. In another study, escitalopram administration led to a significantly greater reduction in the Hamilton Depression Rating Scale score compared to a placebo, as well as in the Hamilton Anxiety Rating Scale score. In one study, citalopram and psychological interventions were both effective in reducing the symptoms of depression and anxiety and, in another study, sertraline was modestly more effective than CBT at 12 weeks in reducing the symptoms of depression. Conclusions: SSRIs may be effective in reducing the symptoms of depression in patients on chronic hemodialysis. SSRI administration, at the dosage used in the studies included in the present systematic review, seems safe in most hemodialysis patients. However, the paucity of studies and the limited number of patients included in the trials may suggest that further randomized, controlled studies are needed to determine if SSRIs may be used routinely in daily clinical practice in such a population.

Entero-Cutaneous and Entero-Atmospheric Fistulas: Insights into Management Using Negative Pressure Wound Therapy.

Enteric fistulas are a common problem in gastrointestinal tract surgery and remain associated with significant mortality rates, due to complications such as sepsis, malnutrition, and electrolyte imbalance. The increasingly widespread use of open abdomen techniques for the initial treatment of abdominal sepsis and trauma has led to the observation of so-called entero-atmospheric fistulas. Because of their clinical complexity, the proper management of enteric fistula requires a multidisciplinary team. The main goal of the treatment is the closure of enteric fistula, but also mortality reduction and improvement of patients' quality of life are fundamental. Successful management of patients with enteric fistula requires the establishment of controlled drainage, management of sepsis, prevention of fluid and electrolyte depletion, protection of the skin, and provision of adequate nutrition. Many of these fistulas will heal spontaneously within 4 to 6 weeks of conservative management. If closure is not accomplished after this time point, surgery is indicated. Despite advances in perioperative care and nutritional support, the mortality remains in the range of 15 to 30%. In more recent years, the use of negative pressure wound therapy for the resolution of enteric fistulas improved the outcomes, so patients can be successfully treated with a non-operative approach. In this review, our intent is to highlight the most important aspects of negative pressure wound therapy in the treatment of patients with enterocutaneous or entero-atmospheric fistulas.

The pediatric DAV-expert algorithm: A GAVeCeLT/GAVePed consensus for the choice of the most appropriate venous access device in children.

In pediatric patients, the choice of the venous access device currently relies upon the operator's experience and preference and on the local availability of specific resources and technologies. Though, considering the limited options for venous access in children if compared to adults, such clinical choice has a great critical relevance and should preferably be based on the best available evidence. Though some algorithms have been published over the last 5 years, none of them seems fully satisfactory and useful in clinical practice. Thus, the GAVePed-which is the pediatric interest group of the most important Italian group on venous access, GAVeCeLT-has developed a national consensus about the choice of the venous access device in children. After a systematic review of the available evidence, the panel of the consensus (which included Italian experts with documented competence in this area) has provided structured recommendations answering 10 key questions regarding the choice of venous access both in emergency and in elective situations, both in the hospitalized and in the non-hospitalized child. Only statements reaching a complete agreement were included in the final recommendations. All recommendations were also structured as a simple visual algorithm, so as to be easily translated into clinical practice.

Geriatric Depression Scale predicts mortality in elderly patients on chronic hemodialysis.

INTRODUCTION: The aim of this study was to determine if the Geriatric Depression Scale (GDS) was predictor of mortality in elderly patients on chronic hemodialysis (HD). METHODS: A total of 140 HD patients ≥65 years were studied. Symptoms of depression were assessed through GDS and cognitive function through the Mini Mental State Examination (MMSE). GDS scores 0-9 are considered normal (Group 1); scores of 10-20 (Group 2) and 21-30 (Group 3) indicate mild and severe depression. RESULTS: Median GDS was 13 (11-15): 54 patients in Group 1, 49 in Group 2, and 37 in Group 3. After a follow-up of 58.85 ± 38.8 months, 94 patients died and 46 were alive. Kaplan-Meier survival was significantly lower in patients of Groups 2 and 3 than in Group 1 (log-rank χ2 : 101.9; DF: 2; p < 0.0001). According to Cox regression analysis, mortality was associated with age and GDS, and inversely associated with MMSE and Kt/V. CONCLUSION: GDS predicts mortality in elderly HD patients.

Splenic abscess with spontaneous gastrosplenic fistula: case report and review of the literature.

Gastrosplenic fistula (GSF) is an unusual event that might occur in patients with various gastric or splenic diseases. While GSF related to gastric and splenic malignancies is well-documented in the literature, cases of GSF due to a splenic abscess are extremely rare. We experienced the case of a 49-year-old man with a medical history of tricuspid cardiac valve replacement for infective endocarditis who presented with a sudden onset of anemia and melena. With the assistance of imaging and endoscopy, a primary splenic abscess complicated by spontaneous GSF was diagnosed. A prompt splenectomy with partial gastrectomy was performed. GSF is a serious occurrence associated with a high risk of morbidity and mortality. The early recognition of GSF related to a splenic abscess is crucial to prevent major complications. Surgical resection with splenectomy and partial gastrectomy is frequently preferred for the treatment of large abscesses with GSF.

Post-dialysis fatigue and serum S100B protein in patients on chronic hemodialysis. A pilot study.

BACKGROUND: Aim of the present study was to assess whether post-dialysis fatigue (PDF) may be related to pre- or post-dialysis levels of serum S100B protein. Hemodialysis patients (HD) who answered to be fatigued after their hemodialysis sessions when asked: "Do you feel worse after dialysis? if they answered yes" were considered to suffer from PDF. Serum Interleukins (IL-1ß, IL-6, IL-10), TNF-α and S100B were assessed by ELISA kit. RESULTS: Thirty HD patients were studied: 22 (73.4%) reported to suffer from PDF. Serum S100B post-dialysis levels (median [IQR] = 17.4 µg [7.1 to 30.9]) were significantly higher than serum S100B pre-dialysis levels (median [IQR] = 5 µg [1.4 to 22.1]; p = 0.0001). S100B post-dialysis was significantly higher than S100B pre-dialysis either in patients with PDF or without PDF. CONCLUSIONS: Pre- and post-dialysis values of serum S100B and its delta did not differ significantly between patients with and without PDF and were not associated with the length of the TIRD in patients on chronic hemodialysis.

Surgical complications of oncological treatments: A narrative review.

Gastrointestinal complications are common in patients undergoing various forms of cancer treatments, including chemotherapy, radiation therapy, and molecular-targeted therapies. Surgical complications of oncologic therapies can occur in the upper gastrointestinal tract, small bowel, colon, and rectum. The mechanisms of action of these therapies are different. Chemotherapy includes cytotoxic drugs, which block the activity of cancer cells by targeting intracellular DNA, RNA, or proteins. Gastrointestinal symptoms are very common during chemotherapy, due to a direct effect on the intestinal mucosa resulting in edema, inflammation, ulceration, and stricture. Serious adverse events have been described as complications of molecular targeted therapies, including bowel perforation, bleeding, and pneumatosis intestinalis, which may require surgical evaluation. Radiotherapy is a local anti-cancer therapy, which uses ionizing radiation to cause inhibition of cell division and ultimately lead to cell death. Complications related to radiotherapy can be both acute and chronic. Ablative therapies, including radiofrequency, laser, microwave, cryoablation, and chemical ablation with acetic acid or ethanol, can cause thermal or chemical injuries to the nearby structures. Treatment of the different gastrointestinal complications should be tailored to the individual patient and based on the underlying pathophysiology of the complication. Furthermore, it is important to know the stage and prognosis of the disease, and a multidisciplinary approach is necessary to personalize the surgical treatment. The purpose of this narrative review is to describe complications related to different oncologic therapies that may require surgical interventions.

The spectrum of pneumatosis intestinalis in the adult. A surgical dilemma.

Pneumatosis intestinalis (PI) is a striking radiological diagnosis. Formerly a rare diagnostic finding, it is becoming more frequently diagnosed due to the wider availability and improvement of computed tomography scan imaging. Once associated only with poor outcome, its clinical and prognostic significance nowadays has to be cross-referenced to the nature of the underlying condition. Multiple mechanisms of pathogenesis have been debated and multiple causes have been detected during the years. All this contributes to creating a broad range of clinical and radiological presentations. The management of patients presenting PI is related to the determining cause if it is identified. Otherwise, in particular if an association with portal venous gas and/or pneumoperitoneum is present, the eventual decision between surgery and non-operative management is challenging, even for stable patients, since this clinical condition is traditionally associated to intestinal ischemia and consequently to pending clinical collapse if not treated. Considering the wide variety of origin and outcomes, PI still remains for surgeons a demanding clinical entity. The manuscript is an updated narrative review and gives some suggestions that may help make the decisional process easier, identifying patients who can benefit from surgical intervention and those who can benefit from non-operative management avoiding unnecessary procedures.

European recommendations on the proper indication and use of peripheral venous access devices (the ERPIUP consensus): A WoCoVA project.

Since several innovations have recently changed the criteria of choice and management of peripheral venous access (new devices, new techniques of insertion, new recommendations for maintenance), the WoCoVA Foundation (WoCoVA = World Conference on Vascular Access) has developed an international Consensus with the following objectives: to propose a clear and useful classification of the currently available peripheral venous access devices; to clarify the proper indication of central versus peripheral venous access; discuss the indications of the different peripheral venous access devices (short peripheral cannulas vs long peripheral cannulas vs midline catheters); to define the proper techniques of insertion and maintenance that should be recommended today. To achieve these purposes, WoCoVA have decided to adopt a European point of view, considering some relevant differences of terminology between North America and Europe in this area of venous access and the need for a common basis of understanding among the experts recruited for this project. The ERPIUP Consensus (ERPIUP = European Recommendations for Proper Indication and Use of Peripheral venous access) was designed to offer systematic recommendations for clinical practice, covering every aspect of management of peripheral venous access devices in the adult patient: indication, insertion, maintenance, prevention and treatment of complications, removal. Also, our purpose was to improve the standardization of the terminology, bringing clarity of definition, and classification.

Tube feeding in patients with head and neck cancer undergoing chemoradiotherapy: A systematic review.

Patients with head and neck cancer (HNC) are frequently malnourished at the time of diagnosis and before beginning treatment. In addition, chemoradiotherapy causes or exacerbates symptoms such as alteration or loss of taste, mucositis, xerostomia, fatigue, nausea, and vomiting, with consequent worsening of malnutrition. If obstructing cancer and/or mucositis interferes with swallowing, enteral nutrition should be delivered by a nasogastric tube (NGT) or percutaneous endoscopic gastrostomy (PEG). To review studies comparing NGT's and PEG's nutrition outcomes, survival, hospitalizations, radiotherapy interruptions, quality of life, and swallowing function. Two hundred fifty publications were identified via electronic databases. 26 manuscripts that met the inclusion criteria were included for analysis. We divided the analysis in two sections: (1) comparison of enteral nutrition through NGT or PEG and (2) comparison of reactive PEG (R-PEG) and prophylactic PEG (P-PEG). They have comparable nutrition outcomes, number of radiotherapy interruptions, survival, and quality of life, whereas swallow function seems better with NGT. PEG may be associated with major complications such as exit-site infection, malfunction, leakage, pain, pulmonary infection, and higher costs. Nevertheless, NGTs dislodged more often; patients find NGTs more inconvenient; NGTs may cause aspiration pneumonia; P-PEG and R-PEG have similar nutrition outcomes, number of radiotherapy interruptions, and survival. PEG does not have better nutrition, oncologic, and quality-of-life outcomes than NGT. Prophylactic feeding through NGT or PEG, compared with reactive feeding, does not offer significant advantages in nutrition outcomes, radiotherapy interruptions, and survival. However, the number of prospective randomized studies on this topic is limited; consequently, definitive conclusions cannot be drawn. Further adequate, prospective randomized studies are needed.

Bowel perforation due to chronic idiopathic megacolon: Case report and literature review.

INTRODUCTION AND IMPORTANCE: Chronic idiopathic megacolon is a rare condition characterized by an irreversible distension of the colon in the absence of organic disease. The pathogenesis of this condition is still unclear and the data in literatures are not consistent. CASE PRESENTATION: We report a case of an 87-years-old woman affected by bowel perforation in chronic idiopathic megacolon. The patient underwent an emergency subtotal colectomy with terminal ileostomy. The postoperative was uneventful. At the histopathological examination, no organic cause of megacolon was found, so a diagnosis of idiopathic megacolon was done. CLINICAL DISCUSSION: Idiopathic megacolon is difficult to diagnose due to the lack of specific clinical manifestations and pathological features. If not carefully investigated, can lead to severe complications such as perforation of the dilated bowel and subsequent peritonitis and sepsis, metabolic and electrolyte abnormalities. The protocols for management of IMC remains controversial. To achieve a good long-term outcome, early intervention is recommended. CONCLUSION: Early diagnosis of idiopathic megacolon is needed to perform the best therapeutic strategy and prevent complications, but further studies are needed.
