OBJECTIVETo improve the understanding of recognizing and diagnosis of neonatal necrotizing enterocolitis (NEC), imaging assessment of neonates with NEC was analyzed retrospectively.

METHODData of 211 cases of NEC were retrospectively collected from the Department of Neonatology, Children's Hospital of Chongqing Medical University between Jan.1(st) 2006-Dec.31(st) 2011.

RESULTAnalysis of abdominal X-ray of 211 cases showed that there were 40 cases (19.0%) who had no changes on each X-ray, 47 cases (22.3%) had improvement and 23 cases (10.9%) became worse. In the group of no changes, positive rate with good prognosis was 97.5% and with poor prognosis, it was 2.5%. In the group of improvement, positive rate with good prognosis was 97.9%, and the contrary was 2.1%. Positive rate with good prognosis was 56.5%, and the contrary was 43.5% in worse group. Chi-square analysis of the three groups showed χ(2) = 31.742, P < 0.01. Comparison of detection rate of pneumoperitoneum on abdominal X-ray (16.0%, 12/75) and Doppler US (1.3%, 1/75), χ(2) = 10.191, P < 0.05, portal pneumatosis on abdominal X-ray(1.3%, 1/75) versus Doppler US (12.0%,9/75), χ(2) = 6.857, P < 0.05. Surgical timing mostly corresponded to pneumoperitoneum (OR = 19.543) and intestinal obstruction (OR = 19.527) of abdominal X-ray. The logistic regression equation is y = -2.915-1.588x1+2.972x4+2.973x7 + 1.711x9 (χ(2) = 101.705, P < 0.01).

CONCLUSIONAbdominal X-ray is the most important method of diagnosis of NEC, the group of deterioration of abdominal X-ray has obvious bad prognosis differ from no change group and better group. Comparison with abdominal X-ray and Doppler US, the former in pneumoperitoneum positive rate was higher than the latter, at the same time, portal pneumatosis on Doppler US is more sensitive to abdominal X-ray, the value of two imaging assessments both supplement each other. Surgical timing mostly corresponds to pneumoperitoneum and intestinal obstruction.

Intestinal malrotation is a congenital disorder that results from the failure of normal bowel rotation and fixation during the 5th gestational week. The incidence of intestinal malrotation is <0.2%, but prompt diagnosis is important because this anomaly can cause midgut volvulus and lead to fatalities. Compared to infants presenting with acute symptoms, such as abdominal pain, vomiting, or diarrhea, adult patients complain of intermittent self-limited abdominal pain. We present a case of intestinal malrotation complicated by midgut volvulus improved with conservative care in a 70-year-old man. The diagnosis was suggested on the basis of imaging findings.

Self-expandable stents are widely available for the treatment of perforation of the gastrointestinal tract. Because of the risk of migration, there has been no report of the use of self-expandable stents for the treatment of perforation of the colon or rectum. This is a report of successful treatment of iatrogenic colonic perforation during balloon dilatation of anastomotic stricture with a fully covered stent. Fully covered, self-expandable metallic stents can be considered useful tools for management of this condition.

Arterio-enteric fistula is a very rare cause of massive lower gastrointestinal hemorrhage. We report here on a case of massive hematochezia caused by iliac arterio-colic fistula in a 60-year-old woman who had a recent history of spinal surgery for herniated nucleus pulposus. Abdomen computed tomography showed the extravasation of radiocontrast media from right iliac artery encased by an intraabdominal abscess into the adjacent dilatated colon. Also, diagnostic angiography revealed the active extravasation of radiocontrast media via a fistula between right iliac artery and colon. Although successful endovascular exclusion of the fistula with stent graft and coils was performed, disseminated intravascular coagulation and multi-organ failure were developed.

BACKGROUND/AIMS: A stercoral perforation of the colon (SPC) is a rare, life-threatening disease. The aim of this study was to represent the definition of SPC and help the diagnosis and treatment of this condition. METHODS: We reviewed 92 medical records of patients who underwent operation due to colonic perforation from January 2000 to February 2009 retrospectively. Maurer's diagnostic criteria were used for the diagnosis of SPC. RESULTS: Eight patients (8.7%) were diagnosed as SPC. The age of the patients ranged from 59 to 85 years old. All of the patients were female and had a history of long-standing constipation. Only two patients (25%) were diagnosed as SPC preoperatively. The site of perforation of all patients was sigmoid colon. The methods of operation were Hartmann's procedure (7 cases), and primary repair with sigmoid loop colostomy (1 case). There were one recurrence and two deaths (25%) due to sepsis and multiple organ failure. CONCLUSIONS: SPC should be considered in chronically constipated, and bedridden patients who present with acute abdomen. Hartmann's procedure is the treatment of choice in most situations. Mortality is high but can be minimized with early definitive surgery.

Mesenteric lymphangiomas are rare abdominal masses that are seldom associated with small bowel volvulus, and especially in adult patients. We report here on an unusual case of small bowel volvulus that was induced by a mesenteric lymphangioma in a 43-year-old man who suffered from repeated bouts of abdominal pain. At multidetector CT, we noticed whirling of the cystic mesenteric mass and the adjacent small bowel around the superior mesenteric artery. Small bowel volvulus induced by the rotation of the mesenteric lymphangioma was found on exploratory laparotomy. Lymphangioma should be considered as a rare cause of small bowel volvulus in adult patients.

Intestinal obstruction is a common surgical emergency. Transmesenteric hernia is an unusual cause of bowel obstruction that may result in irreversible damage of the bowel and a fatal outcome. Once incarceration of the bowel occurs, strangulation and gangrene follow immediately. The mortality rate associated with this condition is about 15%, but in the presence of gangrene of the bowel, the mortality rate is more than 50%. An accurate preoperative diagnosis of a transmesenteric hernia is very difficult and rarely made. Therefore, in patients with small bowel obstruction, in the absence of a history of previous surgery to suggest adhesions or an external hernia, the possibility of a transmesenteric hernia must be considered. We describe a case with gangrene of a long segment of the small bowel caused by a transmesenteric hernia through a large defect of small bowel mesentery in a child.

Intestinal neuronal dysplasia (IND) type B is a disease of the submucosal plexus of intestine manifesting chronic intestinal obstruction or severe chronic constipation. IND is one of intestinal dysganglionoses and clinically closely associated with Hirschsprung's disease. Until recently, it is not fully clear whether IND is a congenital malformation or an acquired secondary condition related to some gastrointestinal problems. However, recently published data and consensus reports have enhanced our understanding of the pathogenesis and management of IND. The aim of this paper was to review the current state of knowledge regarding the controversial issues of IND including the etiology, classification, diagnostic criteria, and available therapeutic intervention.

BACKGROUND/AIMS: The role of double balloon enteroscopy (DBE) is still evolving. The aim of this study was to compare the diagnostic yield of DBE with that of small bowel series (SBS). METHODS: We enrolled patients with suspected small bowel disease consecutively, and performed both DBE and SBS in all patients. RESULTS: Eighteen patients (M:F=12:6, 14-82 years) were included. Indications for small bowel evaluation were obscure gastrointestinal bleeding (10), abdominal pain (5), diarrhea (2) and abnormal CT finding (1). Of 10 obscure gastrointestinal bleeding patients, 6 showed the same findings in both studies. However, 4 showed negative findings in SBS while DBE detected erosions or ulcerations. Of 5 abdominal pain patients, 3 showed the same results in both studies. However, 2 demonstrated different results. One was suspected of early Crohn's disease in SBS, but proved to be normal in DBE, and the other was suspected of malignancy in SBS but was suspected of benign ulcers in DBE. Of 2 chronic diarrhea patients, one was diagnosed as Crohn's disease in both studies. The other was suspected of tuberculosis in SBS but diagnosed as lymphangiectasia by DBE with biopsy. One patient with jejunal wall thickening in CT proved to be normal in both DBE and SBS. There were no serious complications associated with DBE and SBS. CONCLUSIONS: DBE is better than SBS in terms of diagnostic accuracy. DBE may become an important method for the evaluation of small bowel diseases.
