A 61-year-old gentleman was admitted with progressive symptoms of cervical myelopathy. An MRI performed showed severe compression from C3-6 with cord signal changes. He was offered surgical intervention but the operation had to be delayed because of worsening abdominal distension. X-rays performed showed a severely dilated colon measuring >12 cm. A CT did not show any obstructive cause. He was managed conservatively for more than 2 weeks but did not improve. As his symptoms continued to worsen, a decision was made to proceed with a C3-6 posterior decompression and fusion, despite the theoretical risk of bacterial translocation predisposing him to infection...

The main therapeutic basis for a case of organophosphate poisoning is a combination therapy which includes atropine as an anticholinergic drug and pralidoxime. If the poisoning is severe, a high dose of this combination of medicines may be needed, but this may cause serious side effects: paralytic ileus or even megacolon; however, these gastrointestinal events are very rare. Here, we report a case of organophosphate poisoning where atropine therapy was given and led to drug-associated toxic megacolon.

Clostridium difficile infection (CDI) is the main cause of nosocomial diarrhea in industrialized countries and the source of a growing number of cases of diarrhea in the community. The outbreak of the hypervirulent strain belonging to ribotype 027 has increased the incidence and severity of CDI in some countries. Although CDI usually courses as a mild diarrhea it can lead to severe forms such as toxic megacolon or septic shock. One of every 2 episodes of CDI is not diagnosed in Spanish hospitals due to a lack of clinical suspicion or the use of insensitive diagnostic methods...

Ulcerative Colitis (UC) is a chronic inflammatory disease involving the colon, with alternating periods of remission and activity. Exacerbations can be severe and associated with complications and mortality. Diagnosis of severe UC is based on clinical, biochemical and endoscopic variables. Patients with severe UC must be hospitalized. First line therapy is the use of intravenous corticoids which achieve clinical remission in most patients. However, 25% of patients will be refractory to corticoids, situation that should be evaluated at the third day of therapy...

Patients suffering from chagasic megacolon must have an intact mucosal barrier as they survive this chronic disease for decades. A key structure of the mucosal barrier are epithelial cells. Vasoactive-intestinal-peptide (VIP)-positive nerve fibres are involved in influencing, e.g., epithelial cell proliferation, mucus secretion (e.g., mucin 2 and trefoil factor 3 of goblet cells) and inflammation or autoimmunity, all putative and/or known factors altered in chagasic megacolon. We analyzed qualitatively and quantitatively goblet cells, their specific markers, such as mucin 2 (MUC2) and trefoil factor 3 (TFF3) and enterocytes, the relation of VIP-immunoreactive nerve fibres to the epithelia, the distribution of gelsolin, a protein involved in chronic inflammation processes in the epithelia, and the proliferation rate of epithelial cells by combined 4',6-diamidino-2-phenylindole (DAPI) and phosphohistone-H3 (PHH3) staining...

To study the effect of intra-abdominal hypertension (IAH) on the frequency of pneumonia with an experimental study, thirteen Sprague-Dawley rats were included. Eight out of thirteen animals were randomly assigned to receive 10 ml of benzalkonium chloride 0.2% (megacolon group) and five animals received 10 ml NaCl 0.9% (controls). Animals were anaesthetized by intramuscular delivery of ketamine. The incidence of positivity for bacteria lung tissue cultures and mesenteric lymph node cultures was assessed at the 21st day after animals' sacrification, or before in case of death...

The clinical spectrum of Clostridium difficile infection can range from benign gastrointestinal colonization to mild diarrhea and life threatening conditions such as pseudomembranous colitis and toxic megacolon. Extraintestinal manifestations of C. difficile are rare. Here, we report a patient with a history of an endovascular aortic aneurysm repair (EVAR) presenting with an endovascular leak complicated by C. difficile bacteremia and a mycotic aneurysm. He was successfully treated with an explant of the EVAR, an aorto-left renal bypass, and aorto-bi-iliac bypass graft placement along with a six-week duration of intravenous vancomycin and oral metronidazole...

BACKGROUND & AIM: Hirschsprung disease is caused by failure of enteric neural crest cells (ENCCs) to fully colonize the bowel, leading to bowel obstruction and megacolon. Heterozygous mutations in the coding region of the RET gene cause a severe form of Hirschsprung disease (total colonic aganglionosis). However, 80% of HSCR patients have short-segment Hirschsprung disease (S-HSCR), which has not been associated with genetic factors. We sought to identify mutations associated S-HSCR, and used the CRISPR/Cas9 gene editing system to determine how mutations affect ENCC function...

The laparoscopic sacrocolpopexy is the treatment of choice of pelvic organ prolapses since more than twenty years. The laparoscopic lateral suspension with mesh is an alternative technique. Its originality is the subperitoneal passing of the lateral arm of the mesh in the lateral abdominal wall, leaving the skin above the iliac crest, in a place without risks of vascular, nerve, bowel injuries. We report in this article the results of the three main publications on the subject. The indications are cystocele and apical descent...

AIM: To evaluate the contribution of CT scanning to the management of patients with severe acute exacerbation of colitis (SAC) complicating inflammatory bowel disease (IBD), in particular, its contribution to surgical decision making. METHOD: All patients who were admitted to our institution for SAC complicating IBD, were divided into Group A (surgical treatment) and B (medical treatment). Admission CT scan results were compared between the 2 groups. RESULTS: From 2006 to 2015, 54 patients (26 males, median age= 39 (17-71) years) presented with SAC were divided into Group A (n=41, 76%) and B (n=13, 24%)...

Hirschsprung disease (HD) in late childhood is uncommon and often undiagnosed or misdiagnosed. However, in a patient with Hirschsprung disease, of greater significance is the occurrence of life threatening enterocolitis. In its more severe form, this is associated with gross dilatation of the colon and profound toxaemia, the combination being termed toxic megacolon. Because of its relative rarity, we report a case of 10-year-old child who had a history of chronic constipation for nine years. He later developed complications and presented to the emergency department with toxic megacolon, a rare occurrence due to neglected constipation...

Although most children with Hirschsprung disease ultimately do well, many experience a variety of ongoing problems after pull-through surgery. The most common include obstructive symptoms, soiling, enterocolitis and failure to thrive. The purpose of this guideline is to present a rational approach to the management of postoperative obstructive symptoms in children with Hirschsprung disease. The American Pediatric Surgical Association Board of Governors established a Hirschsprung Disease Interest Group. Group discussions, literature review and expert consensus were then used to summarize the current state of knowledge regarding causes, methods of diagnosis, and treatment approaches to children with obstructive symptoms following pull-through for Hirschsprung disease...

Congenital hypothyroidism (CH) may present with nonspecific signs and symptoms, though, majority of infants can be asymptomatic. Therefore, understimation and delay in diagnosis may result in severe complications. A 5-month-old female admitted to our clinic with the history of repeated surgical operations due to the diagnosis of congenital aganglionic megacolon. Investigations performed in our clinic revealed the diagnosis of congenital (primary) hypothyroidism due to thyroid agenesis. Histopathologic evaluation of previously resected colon sample revealed normal ganglionic cell included colon...

BACKGROUND AND OBJECTIVE: The cardinal diagnostic sign of congenital aganglionic megacolon, or Hirschsprung's disease (HD), is an aganglionic segment of the distal colon or rectum. To determine the surgical planning of a radiological transition zone (TZ) in HD, this study investigated the association between a radiological TZ and the bowel resection length. METHODS: A prospective observational study was conducted in children (n = 192) with suspected HD determined by radiological TZ on contrast barium enema, and who underwent pull-through operations...

BACKGROUND: Hirschsprung's disease (HSCR) is a type of megacolon induced by deficiency or dysfunction of ganglion cells in the distal intestine and is associated with developmental disorders of the enteric nervous system. To explore the mechanisms of HSCR, we analyzed the RNA-sequencing data of the expansion and the narrow segments of colon tissues separated from children with HSCR. METHODS: RNA-sequencing of the expansion segments and the narrow segments of colon tissues isolated from children with HSCR was performed...

Chagas' disease still reaching about 10 million people in the world. In South America, one of the most severe forms of this disease is the megacolon, characterized by severe constipation, dilated sigmoid colon and rectum and severe malnutrition. Previous data suggested that mast cells and serotonin (5-HT) expression could be involved in intestinal homeostasis control, avoiding the chagasic megacolon development. The aim at this study was to characterize the presence of mast cells and expression of serotonin in chagasic patients with and without megacolon and evaluate the relation between mast cells, serotonin and megacolon development...

It is widely accepted that Clostridium difficile exploits dysbiosis and leverages inflammation to thrive in the gut environment, where it can asymptomatically colonize humans or cause a toxin-mediated disease ranging in severity from frequent watery diarrhea to pseudomembranous colitis or toxic megacolon. Here, we synthesize recent findings from the gut microbiota and enteric pathogenesis fields to inform the next steps toward a better understanding of C. difficile infection (CDI). In this review, we present a model in which the lifestyle of C...
