Large bowel volvulus in children. Review of a case material and the literature

Recurrent Sigmoid Volvulus in Children-Our Experience and Systematic Review of the Current Literature

Sigmoid volvulus (SV) occurs rarely in children. After encountering two cases of recurrent SV, we reviewed the literature to define the recurrence risk, identify outcome predictors and to give treatment recommendations. We found 256 cases reported in children (mean age 10.2 years, gender ratio (m:f) 2.3:1). Associations exist with Hirschsprung disease (HD) in 10%, neurodevelopmental disorders in 10.9% and chronic constipation in 10.2%. Common symptoms and clinical signs were abdominal pain (85%), distension (85%), tenderness (54%) and vomiting (59%). Signs of peritonitis were present in 14% and indicated a gangrenous sigmoid (X2 = 45.33; p < 0.001). A total of 183 had abdominal radiographs, and 65% showed a positive 'coffee-bean-sign'. Contrast enemas were positive in 90%. A total of 124 patients underwent laparotomy; in 41 cases, the sigmoid was gangrenous and associated with more complications (X2 = 15.68; p < 0.001). Non-operative treatment (NOT) like endoscopic, fluoroscopic or rectal tube decompression was performed in 135 patients and successful in 79% with a 38-57% recurrence rate. A total of 73 patients subjected to elective surgery: 50 underwent sigmoid resection; 17 had surgery for HD. Clinicians should consider SV in all children with abdominal pain, distension and vomiting. Gangrene carries a higher morbidity. After successful NOT we recommend counselling about the recurrence risk and definitive surgery should be advised. HD is frequent in newborns but sometimes found in older children.

Pediatric colonic volvulus: A single-institution experience and review

BACKGROUND/PURPOSE

Pediatric colonic volvulus is both rare and underreported. Existing literature consists only of case reports and small series. We present an analysis of cases (n=11) over 15 years at a single institution, focusing on workup and diagnosis.

METHODS

This was an institutional review board approved single-institution retrospective chart review of 11 cases of large bowel volvulus occurring over 15 years (2000-2015).

RESULTS

In our series, the most common presenting symptoms were abdominal pain and distention. Afflicted patients often had prior abdominal surgery, a neurodevelopmental disorder or chronic constipation. Of the imaging modalities utilized in the 11 patients studied, colonic volvulus was correctly diagnosed by barium enema in 100% of both cases, CT in 55.6% of cases and by plain radiography of the abdomen in only 22.2%of cases. Colonic volvulus was confirmed by laparotomy in all cases. The cecum (n=5) was the most often affected colonic segment, followed by the sigmoid (n=3). Operative treatment mainly consisted of resection (63.6%) and ostomy creation (36.4%). Colopexy was performed in 18.2% of cases.

CONCLUSIONS

Plain abdominal radiography may be performed as an initial diagnostic study, however, it should be followed CT or air or contrast enema in children where there is high clinical suspicion and who do not have indications for immediate laparotomy. CT may be the most specific and useful test in diagnosis of colonic volvulus and has the added advantage of detection of complications including bowel ischemia. We demonstrate a range of diagnostic and therapeutic modalities for pediatric colonic volvulus. This underscores the need for further study to draft standard best practices for this life-threatening condition.

LEVEL OF EVIDENCE

Prognosis Study: Level IV. Study of a Diagnostic Test: Level III.

Colonic volvulus detected by CT scan in a case with mental retardation and prune belly syndrome

Colonic volvulus is a rare disease in children. Delayed diagnosis of the condition can often be fatal, especially in pediatric patients with mental retardation. We herein present the case of a female pediatric patient with colonic volvulus, prune belly syndrome, and mental retardation. Preoperative CT scans showed the characteristic signs of this disease. The volvulus occurred in the proximal colon of the colostomy. The release of the colonic volvulus and reconstruction of the colostomy were performed without the resection of the ischemic colon. The postoperative clinical course was uneventful.

Colonic volvulus in children with intestinal motility disorders

BACKGROUND

Chronic intestinal pseudo-obstruction (CIP) is a condition characterized by symptoms of bowel obstruction in the absence of an anatomical cause. Patients with CIP and chronic intractable constipation (CIC) can also develop anatomical obstruction, and the presenting symptoms mimic those of underlying pseudo-obstruction.

OBJECTIVES

Our objectives were to evaluate the incidence, clinical presentation, and diagnostic investigations of colonic volvulus in children with intestinal motility disorders and to differentiate these episodes of colonic volvulus from the underlying motility disorder based on clinical presentation and imaging techniques.

MATERIALS AND METHODS

Patients records of children with colonic volvulus cared for at our institution over the previous 20 years were retrospectively reviewed. We identified 8 patients who were between 2 and 22 years of age at the time of diagnosis with colonic volvulus who also had CIP and CIC.

RESULTS

The mean age +/- SD at presentation with colonic volvulus was 13.2 +/- 5.05 years. All patients presented with worsening of abdominal distension and pain. The mean duration of symptoms of colonic volvulus before seeking medical help was 4.2 days (range 1-7 days). Water-soluble contrast enema was the single most useful investigation for confirming the diagnosis. All patients required surgery. There was no mortality associated with colonic volvulus.

CONCLUSIONS

Clinicians should be vigilant and include volvulus in the differential diagnosis of the acute onset of abdominal distension and pain in patients with CIP and CIC. Delay in diagnosis can result in bowel ischemia and perforation.

Cecal volvulus: a rare cause of bowel obstruction in a pediatric patient diagnosed pre-operatively by conventional imaging studies

Cecal volvulus is an acute surgical condition that is extremely rare in children, with a mortality rate of up to 40%. The clinical symptoms are often non-specific, and pediatric patients frequently have neurological deficits with associated communication difficulties, making the clinical diagnosis extremely challenging. Conventional radiographic imaging studies play a key role in the prospective diagnosis in children. We report a rare case of cecal volvulus in a 12-year-old boy who was diagnosed pre-operatively by abdominal radiographs and a contrast enema.

Recurrent sigmoid volvulus in a sixteen-year-old boy: case report and review of the literature

The authors describe a 16-year-old boy in whom 3 episodes of sigmoid volvulus (SV) occurred over a period of 7 weeks, each time reduced by endoscopy. The child subsequently underwent a successful sigmoid resection with primary anastamosis. Several months after surgery, he remains free of symptoms and is doing well. A review of the literature illustrates the approach to this problem from ancient times until now.

Sigmoid volvulus and unexpected death in the elderly

An 84-year-old female who was found unexpectedly dead at her home was shown at autopsy to have a massively dilated sigmoid colon with twisting of the lower colon on an unusually long mesentery. The volvulus had caused mechanical obstruction of the bowel with critical reduction of the blood supply resulting in intestinal infarction. Death was due to ischaemic necrosis of the lower large intestine with significant fluid and electrolyte sequestration within the bowel lumen, associated with disseminated sepsis. Gastrointestinal disorders that may result in unexpected death are uncommon in adults and may present atypically in the elderly. The diagnosis of unexpected death due to an infarcted sigmoid volvulus may not be established until an autopsy has been undertaken.

Sudden infant death, large intestinal volvulus, and a duplication cyst of the terminal ileum

A previously well 7-week-old boy was found unresponsive and cyanotic in his cot in the morning. Resuscitative attempts achieved only partial response with subsequent terminal cardiac arrest occurring later in the day. At autopsy a large intestinal volvulus was found associated with disseminated Clostridium perfringens sepsis. In addition, a duplication cyst of the terminal ileum was present. Although rare, right-sided colonic volvulus may be a cause of unexpected death in infancy. While predisposing factors to volvulus may include intestinal duplication cysts, the anatomic relation of the duplication to the volvulus must be carefully determined before a causal relation can be accepted; the cyst in this case was most likely incidental to the terminal event.

Volvulus of the transverse colon in children

Volvulus of the transverse colon is extremely rare in children. A case report of this unusual condition in a 9-year-old girl is presented together with a review of the literature. The transverse colon volvulus was managed operatively by detorsion. Four and half months later, she had a similar attack. Colonoscopic detorsion was performed with elective resection of the transverse colon and primary anastomosis. Recovery was uneventful. Possible factors of pathogenesis are discussed, and an outline of diagnostic and therapeutic measures are included.

Recurrent colonic volvulus in children

Recurrent intestinal obstruction caused by colonic volvulus is a rare cause of intestinal obstruction in children. Because the condition is self rectifying at times, the diagnosis can be missed or delayed. The authors present two patients, one with sigmoid volvulus and the other with sigmoid and cecal volvulus, and discuss the diagnosis and management of this condition in children. In view of the recurring nature of this condition, the authors believe that nonoperative treatment of this condition in children has no place beyond the emergency situation and that the definitive treatment should always be surgical.

Sigmoid volvulus in a young patient

The case of an 18-year-old man with sigmoid volvulus and recurrent abdominal pain is presented. He was seen in the emergency department three times in a 4-month period, each time complaining of cramping left lower quadrant pain of one to two hours duration without vomiting or diarrhea. Physical examination on each occasion revealed left lower quadrant tenderness without mass, guarding, or rebound. Radiologic evaluation on the first visit revealed sigmoid volvulus, which was reduced by barium enema. Despite identical clinical presentation on two subsequent occasions, radiologic studies showed no evidence of recurrent volvulus. During the ensuing two years, the patient has had no further symptoms.

Conventional abdominal radiography as a means to rule out ileo-caecal intussusception

The experiences gained with conventional radiographic examinations as a means of excluding childhood ileo-caecal intussusception are presented. According to these, a supplementary barium enema is indicated a) in patients under 6 months of age, b) in patients presenting with scant intestinal gas, c) in patients where the caecum cannot be outlined, d) in patients with a possible mass lesion of the colon, e) in patients with obstruction presumably due to intussusception, and f) in patients with discrepancy between the clinical and radiologic findings (1, 4). In all other patients the barium examination is not used. The key to a successful application of this protocol is a thorough familiarity with the limitations and potentials of the conventional abdominal examination.

Barium peritonitis. Experience of five pediatric cases

Barium peritonitis secondary to perforation of the gut is an infrequent complication of radiological G-I tract examinations. It is thought to imply a high mortality rate. However, this conception seems to be based on data obtained during the early 1950's. More recent case reports and small series indicate a more favourable prognosis depending on effective antibiotics and successful maintenance of severely ill patients. The scant information concerning the fate of pediatric cases warranted presentation of the experience of 5 patients, who all survived. Our approach to treatment and the suggested use of barium studies, in particular barium enema, in obscure abdominal emergency cases are offered.
