Meckel's Diverticulum��Revisited

Meckel''s diverticulum is a true intestinal diverticulum that results from the failure of the vitelline duct to obliterate during the fifth week of fetal development. In about 50% cases, it contains ectopic or heterotopic tissue which can be the cause of complications. A systematic review of literature was undertaken to study the history, incidence, embryoanatomy, clinical presentation, complication and management of Meckel''s diverticulum. Although Meckel''s diverticulum is the most common congenital abnormality of the gastrointestinal tract, it is often difficult to diagnose. It may remain asymptomatic or it may mimic disorders such as Crohn''s disease, appendicitis and peptic ulcer disease.     

Meckel＇s diverticulum manifested by a subcutaneous abscess

This case report describes an extremely rare complication of a Meckel's diverticulum: enterocutaneous fistula of the diverticulum. The presence of Meckel's diverticulum is a well known entity, but subcutaneous perforation of the diverticulum is very rare. Here we report the case of a patient with the complaint of a right lower quadrant abscess, preoperatively diagnosed as enterocutaneous fistula, which was determined intraoperatively to be a fistula resulting from Meckel's diverticulum.     

Perforation of Meckel’s diverticulum with enteroliths

Perforation of Meckel??s diverticulum with enteroliths is a rare complication. Here, we report a case of perforation of Meckel??s diverticulum with enteroliths, which could be accurately diagnosed by the preoperative computed tomography (CT). A 46-year-old man with acute onset of severe abdominal pain, and a localized muscle guarding in the right hypochondrium, had a solitary stone detected in the right abdomen by the radiography. The abdominal CT revealed a saclike outpouching of the small intestine, containing air/fluid levels and an enterolith, with surrounding free air and mesenteric inflammatory change in the right paraumbilical area. He was diagnosed as the perforation of Meckel's diverticulum with enterolith, and the emergency operation was indicated. The perforated Meckel??s diverticulum was identified approximately 90?cm proximal to the ileocecal valve. The diverticulum was transected at the base, and removed. The patient??s postoperative course was uneventful. This case strongly suggested the ability of CT enterography to accurately diagnose pathologies involving the small intestine, such as the perforation of Meckel??s diverticulum, which open premises for its use in the diagnosis of acute abdomen preoperatively.     

HETEROTOPIC GASTRIC MUCOSA IN MECKEL'S DIVERTICULUM INCIDENTALLY FOUND BY DOUBLE BALLOON ENTEROSCOPY

A 45‐year‐old Japanese man who had been suffering from intestinal‐type Behcet's disease was referred to Yamagata University Hospital for enteroscopic examination. Double balloon enteroscopy was performed via the anal route. We identified ulceration of the terminal ileum that was detected previously. In addition, we incidentally recognized a Meckel's diverticulum coexisting with a heterotopic mucosal island nearly 100 cm on the oral side from the ileocecal valve. Meckel's diverticulum did not accompany ulcers and there was no history of bleeding. The heterotopic mucosal island was confirmed as gastric mucosa from biopsy specimens. High‐resolution endoscopic features of heterotopic gastric mucosa in Meckel's diverticulum using a double balloon enteroscopy are considered informative images.     

Intususcepción ileocólica en un adulto causado por divertículo de Meckel invertido

Meckel's diverticulum is the most common congenital abnormality of the gastrointestinal tract. It is found in 2.00% of the population and is more frequent in children. Invagination is an unusual complication that can cause secondary intestinal intussusception. This event is extremely rare and only a few cases have been reported. We present the case of a 19-year-old male who presented with chronic abdominal pain and weight loss of 23 Kg 6 months prior to hospital admittance. The last episode manifested as intense abdominal pain, nausea, vomiting, and diarrhea with a 6-hour progression. Imaging studies established the diagnosis of bowel obstruction and ileocolic intussusception. Laparotomy with ileocolic resection was performed without reducing the intussusception. The histopathologic study reported inverted Meckel's diverticulum at the base of the ileocolic intussusception. Intestinal intussusception in adults, secondary to inverted Meckel's diverticulum is rare and should be considered in the differential diagnosis of patients presenting with abdominal pain and bowel obstruction.     

Abcès cutanés aseptiques récidivants atypiques révélateurs d’une maladie de Crohn

Introduction

We report here a case of chronic inflammatory bowel disease revealed by multiple large cutaneous aseptic distal necrotic ulcers.

Case report

A 44-year-old male presented with high fever at 40 °C associated with multiple necrotic abcesses located on the distal part of his limbs. They were treated successfully by debridment and dressings associated with antibiotics allowing complete healing after 1 month. Six months later, the patient relapsed on his left hand with a short episode of diarrhoea. A total coloscopy revealed a Crohn's disease. Systemic corticotherapy and azathioprine were administered and complete remission was obtained with a 1-year follow-up.

Conclusion

Skin manifestations that this patient presented were atypical because of their number, size, and location, exclusively distally on the limbs. This report illustrates an unusual presentation of Crohn's disease with multiple necrotic ulcers only located on the patient extremities.     

Estrés oxidativo en la enfermedad de Crohn

Crohn's disease (CD) is characterized by transmural inflammation that is most frequently located in the region of the terminal ileum. Although the physiopathological mechanisms of the disease are not yet well defined, the unregulated immune response is associated with high production of reactive oxygen species (ROS). These elements are associated with complex systems known as antioxidant defenses, whose function is ROS regulation, thereby preventing the harmful effects of these elements. However, the presence of an imbalance between ROS production and ROS elimination by antioxidants has been widely described and leads to oxidative stress. In this article, we describe the most significant findings on oxidative stress in the intestinal mucosa and peripheral blood.     

Impacto del estreñimiento crónico en la calidad de vida: mucho más importante de lo que parece

Chronic constipation is highly frequent in the general population (a prevalence of 14%). An underlying organic cause is usually absent, this type of constipation being known as chronic idiopathic constipation (CIC). Although usually considered banal, this disorder has a substantial personal, social and healthcare impact. Several studies have associated CIC with high rates of absenteeism in the workplace and disruption of routine activities. All these factors lead to high direct and indirect healthcare expenditure. Physically, the impact on patients with CIC, who require specialized care, is higher than that of ulcerative colitis or stable Crohn's disease. The psychological impact exceeds that caused by rheumatoid arthritis or hemodialysis. Appropriate treatment can improve HRQL in affected individuals. Recently, prucalopride, a highly selective 5-HT4 receptor agonist has been shown to improve the symptoms of CIC and to have a beneficial effect on HRQL.     

Digestive complications of gallstones lost during laparoscopic cholecystectomy

IntroductionSerious complications can ensue if a gallstone is dropped into the peritoneal cavity during laparoscopic cholecystectomy and not retrieved.Case outlineA 75-year-old-man was admitted with intestinal obstruction 8 years after laparoscopic cholecystectomy. Ultrasound scan and a contrast x-ray of the small bowel showed a gallstone within the small bowel lumen that CT scan had failed to identify. Laparotomy showed a Meckel''s diverticulum plus a 4×6-cm gallstone in the terminal ileum. The gallstone had penetrated into the Meckel''s diverticulum before migrating into the ileum and obstructing it.DiscussionGallstones lost during laparoscopic cholecystectomy can cause an intraperitoneal abscess. In addition, they can migrate through the anterior or posterior abdominal wall or the diaphragm and into the urinary tract or bronchus. The resulting abscess can obstruct the digestive tract or drain into the digestive tract to cause a communicating abscess. It can also drain through the abdominal wall and the digestive tract to cause an enterocutaneous fistula. Lastly, the stone can migrate into the intestine and cause gallstone ileus. Following laparoscopic cholecystectomy, patients with a lost gallstone may suffer from abdominal pain and fever within days or months. Thus, all dropped gallstones should be removed during laparoscopy.     

Enteroliths Causing Intermittent Obstruction in a Patient with Crohn''s Disease

Calcified enteroliths as a cause of intermittent small bowel obstruction is an uncommon clinical entity. The pathophysiological mechanism involves stasis of intestinal contents and has been associated with Meckel's diverticulum, tuberculosis, and regional enteritis. This case describes prophylactic operative intervention in a symptomatic patient with enteroliths as a result of Crohn's disease.     

Meckel's diverticulum masked by a long period of intermittent recurrent subocclusive episodes

Meckel＇s diverticulum （MD） is the most frequent congenital abnormality of the small bowel and it is often difficult to diagnose. It is usually asymptomatic but approximately 4% are symptomatic with complications such as bleeding, intestinal obstruction, and inflammation. The authors report a case of a 7-year-old boy with a one-year history of recurrent periumbilical colicky pain with associated alimentary vomiting, symptoms erroneously related to a cyclic vomiting syndrome but not to MD. The clinical features and the differential diagnostic methods employed for diagnosis of MD are discussed.     

Enterolithiasis Associated with Heal Perforation in Crohn''s Disease

Calcified enteroliths are an uncommon sign of stasis of intestinal contents in the distal small intestine, usually caused by Meckel's diverticulum, Crohn's disease or other stenosing lesion. Although enteroliths are occasionally associated with intestinal obstruction the clinical picture in this case was dominated by perforation of the ileum by a small enterolith. The relevant literature is discussed.     

Outcome of restorative proctocolectomy when the diagnosis is suggestive of Crohn's disease.

Twenty of 81 patients treated by restorative proctocolectomy for presumed ulcerative colitis had some features of Crohn''s disease: 10 were classified as definite Crohn''s disease and 10 as indeterminate colitis. These pathological features were first apparent during synchronous colectomy and pouch construction in 10 of 11 cases. In the remainder, histological features of possible Crohn''s disease were first identified during rectal excision (n = 6), preliminary subtotal colectomy (n = 2), and after pouch excision (= 2). Complications were marginally more common in patients with features of possible Crohn''s disease: pelvic sepsis 30% (Crohn''s disease 30%, indeterminate colitis 30%) v 20%, fistulas 45% (Crohn''s disease 30%, indeterminate colitis 60%) v 16%; ileal stenosis 40% (Crohn''s disease 40%, indeterminate colitis 40%) v 21%, pouchitis 50% (Crohn''s disease 50%, indeterminate colitis 50%) v 26%, and small bowel obstruction 25% (Crohn''s disease 30%, indeterminate colitis 30%) v 13%. Pouch excision or a persistent proximal stoma has been necessary in six patients with possible Crohn''s disease (30%) (Crohn''s disease 3 cases 30%, indeterminate colitis 3 cases 30%) compared with nine (15%) of the remainder. Median hospital stay, however, was the same and stool frequency in those with a functioning pouch were comparable. These results show that there is a higher complication rate if there are features of Crohn''s disease but that the medium term functional results are acceptable if the pouch can be retained.     

The Obligate Anaerobic Faecal Flora of Patients with Crohn's Disease and Their First-Degree Relatives

The obligate anaerobic faecal floras of patients with Crohn's disease, their first-degree relatives, and healthy control subjects were compared. The flora of Crohn's patients contained more anaerobic gram-positive coccoid rods and gram-negative rods than that of healthy subjects; on this basis patients and healthy subjects formed two clusters with minor overlap. Nine of 26 children of Crohn's patients were also included within the Crohn's disease cluster. During 5 to 7 years of follow-up study 3 of them presented with remitting abdominal pain, diarrhoea, or weight loss, and in 1 of them Crohn's disease was diagnosed; none of the 17 children with a normal flora showed symptoms possibly due to Crohn's disease. It is concluded that the abnormal flora may be indigenous to subjects predisposed to Crohn's disease, suggesting a direct or indirect relationship between the abnormal faecal flora and Crohn's disease.     

Maladie de Behçet de l’enfant

Behçet's disease is a chronic multisystem vasculitis of unknown etiology. The disease is commonly described in young adults but can occur in childhood. Diagnosis is based on clinical manifestations since there are no pathognomonic laboratory findings. Early diagnosis in children is challenging due to the insidious nature of the disease and the low sensitivity of adult criteria in the pediatric population. The purpose of this review is to describe the demographic and clinical features of Behçet's disease in childhood, its complications and recent advances in therapeutics highlighting differences with the adult onset disease.     

Système nerveux entérique et maladie de Parkinson

It has become increasingly evident over the last years that Parkinson's disease is a multicentric neurodegenerative disease that affects several neuronal structures outside the substantia nigra, among which is the enteric nervous system. The aims of the present article are to discuss the role of the enteric nervous system lesions in pathology spreading (Braak's hypothesis) and in the gastrointestinal dysfunction encountered in Parkinson's disease. Owing to its accessibility to biopsies, we further discuss the use of the enteric nervous system as an original source of biomarker in Parkinson's disease.     

7 Controversies in Crohn's disease

Despite recent advances in the medical therapy of Crohn's disease, surgery continues to play a central role in the treatment of the disease. The strategy for surgical management of Crohn's disease continues to evolve. This chapter reviews many of the controversies surrounding surgical palliation of complications of Crohn's disease. Included is a discussion of indications for strictureplasty in treatment of intractable intestinal obstruction. Factors influencing long-term outcome with sphincter-saving resection in the treatment of Crohn's colitis are reviewed. Experience with definitive treatment of anal Crohn's disease and repair of rectovaginal fistulas is examined. Finally, recent experience supporting ileocolic resection when acute Crohn's ileitis is identified during laparotomy for right lower quadrant pain is critically evaluated. These controversial aspects of the surgical treatment of Crohn's disease reflect an improved understanding of the natural history of the disease as well as refinement in surgical techniques and better definition of criteria for surgical intervention.     

CROHN'S DISEASE AND SECONDARY AMYLOIDOSIS: EARLY COMPLICATION? A CASE REPORT AND REVIEW OF THE LITERATURE

Secondary amyloidosis is a rare but serious complication of inflammatory bowel disease (IBD), generally seen in Crohn's disease. At least 1% of patients with Crohn's disease develop amyloidosis. In the literature, the time lapse between the onset of Crohn's disease and the diagnosis of amyloidosis has been reported to range from one to 21 years. In most patients, protein‐uria heralded the onset of renal involvement from amyloid and occurred from three to 15 years after Crohn's disease diagnosis. In this case, we estimate secondary amyloidosis occurred before Crohn's disease or early Crohn's disease complication, based on the fact that hypoalbuminaemia and proteinuria was detected approximately one year after the start of gastrointestinal complaints.     

Gastrointestinal stromal tumor causing small bowel intussusception in a patient with Crohn＇s disease

We report a case of jejunoileal intussusception in a 42-year-old patient with Crohn's disease caused by a gastrointestinal stromal tumor. The patient complained of vague diffuse abdominal pain for a period of 4 mo. Intussusception was suspected at computer tomography and magnetic resonance imaging scans. Segmental resection of the small intestine was performed. Pathological examination of the surgical specimen revealed a gastrointestinal stromal tumor as well as aphthous ulcerations and areas of inflammation, which were characteristic of Crohn's disease. This is the first report of small bowel intussusception due to a gastrointestinal stromal tumor coexisting with Crohn's disease.     

Ulcerative Colitis in Infancy

Ulcerative colitis (UC) is a chronic idiopathic inflammatory disorder of colon. Frequency of UC is gradually increasing over few years worldwide. Prevalence is 35 to 100/100 000 people in USA, 1% of them are infants. UC develops in a genetically predisposed individual with altered intestinal immune response. An eight-month-old girl presented with loose bloody stool, growth failure, and moderate pallor. The girl was diagnosed as a case of UC by colonoscopy and biopsy. Treatment was thereafter started with immunosuppressive drugs. After initial induction therapy with parenteral steroid and infliximab, the patient is now on remission with azathioprine and mesalamine. UC is rare in Bangladesh, especially in children, and it is rarer during infancy. Several conditions like infective colitis, allergic colitis, Meckel''s diverticulitis, Crohn''s disease, etc. may mimic the features of UC. So, if a child presents with recurrent bloody diarrhea, UC should be considered as differential diagnosis.
