An unusual cause of intestinal obstruction in an adolescent: a case report and management review.

A 15-year-old boy presented with intestinal obstruction two weeks following a blunt abdominal trauma. He had progressive bilious vomiting without abdominal distension or peritonitis. The contrast computed tomography (CT) scan of the abdomen provided the definitive diagnosis: there was an obstructing duodenal hematoma, which might have been slowly progressing or have arisen from secondary hemorrhage after the initial injury. The boy remained stable over a ten-day period of conservative treatment, and his obstructive symptoms and signs were resolved completely. A follow-up CT scan of the abdomen (16 days after admission) showed an almost complete resolution of the hematoma. Delayed duodenal hematoma causing intestinal obstruction has been reported rarely in previous literature. Occasionally a significant secondary hemorrhage resulting in intestinal obstruction can become life threatening. Clinical follow-up is paramount after initial recovery. Although conservative treatment suffices in most cases, the surgeon should be wary of the need for definitive surgical intervention if there is evidence of ongoing acute hemorrhage or of the obstructing hematoma failing to resolve. Laparoscopic drainage of the hematoma provides optimistic results for patients failing conservative management.

Electrogastrography in the management of pediatric functional dyspepsia and motility disorder.

PURPOSE: Electrogastrography (EGG) is a noninvasive investigation for recording gastric myoelectrical activity. We hypothesize that children with functional dyspepsia (FD) and gastrointestinal (GI) motility disorder have abnormal gastric myoelectrical activity. We aim to study the dyspepsia symptom scores and EGG of these children and compare them with those of the normal population. METHODS: Seventeen children aged 6 to 18 years with persistent dyspepsia symptoms but with normal investigations were recruited as the FD group. Nine children with same age as the FD group with known upper GI motility disorder were recruited as the GI group. Eight normal healthy children were recruited as controls (CL). Dyspepsia symptom score (0-18) was charted, and all had EGG performed. Gastric slow wave frequency of 2 to 4 cycles per minute is defined as normogastria. Electrogastrography is regarded as abnormal when normogastria occurs in less than 70% of recorded time. Wilcoxon rank sum test and Fisher's Exact test were performed with statistical significance at P value equal to .05. RESULTS: Mean dyspepsia symptom score was significantly different in comparing FD and GI with CL groups (FD, 6.71; GI, 5.54; CL, 0.25; P < .001). Abnormal EGG patterns occur more often in FD than in CL (FD, 58.9%; CL, 12.5%; P = .042). Abnormal EGG patterns were found in 55.6% of GI and 12.5% of CL (P = .131). CONCLUSIONS: Electrogastrography is a useful and noninvasive armamentarium for evaluating the abnormal myoelectrical activity in children with FD and GI motility disorder.

Complications of peptic ulcer disease in children and adolescents: minimally invasive treatments offer feasible surgical options.

PURPOSE: Surgery for complications of peptic ulcer disease (PUD) carries a significant morbidity and even mortality. The aim of this study was to determine the efficacy, safety, and outcome of children and adolescents undergoing minimally invasive treatment of bleeding and perforation complicating PUD. METHODS: One hundred thirty-two consecutive patients aged 6 to 17 years managed endoscopically for bleeding and laparoscopically for perforation from January 1999 to February 2006 were reviewed. RESULTS: Thirty children had significant endoscopic stigma of recent hemorrhage. Primary endoscopic hemostasis was achieved in most cases except one requiring further endoscopic hemostasis. Seventeen patients with perforation underwent laparoscopic patch repair. Four patients were converted to open repair because of technical difficulty and the large size of the ulcer. All patients had a course of proton pump inhibitors postoperatively. Ninety percent of patients had Helicobacter pylori infestation. Triple therapy was given. Two patients defaulted triple therapy and presented later with recurrent ulcer bleeding. All others remained asymptomatic on follow-up (average, 32.6 months). CONCLUSIONS: Endoscopic hemostasis of bleeding peptic ulcer is effective and safe in children. With stringent criteria, laparoscopic patch repair of perforation can be applied safely to most pediatric patients. Eradication of H pylori and subsequent antiulcer medication are integral in the management of complicated PUD.
