Peutz-Jeghers syndrome with intermittent upper intestinal obstruction: A case report and review of the literature.

RATIONALE: Peutz-Jeghers syndrome (PJS) is an autosomal dominant genetic syndrome characterized by a unique type of gastrointestinal hamartomatous polyp associated with oral and anal mucocutaneous pigmentations. Peutz-Jeghers polyps occur most numerously in the small intestine but frequently in the colon and stomach, only a few cases have been reported in the duodenum. PATIENT CONCERN: A further family history survey discovered 10 out of 14 members of the family (in 4 generations) had mucocutaneous pigmentations, but many of them were living in rural areas where they had no access to specialized medical services, so none were checked with endoscopy for polyps of hamartoma. DIAGNOSES: We report the case of a boy patient with mucocutaneous pigmentations over the lips, and a history of recurrent bouts of vomit and anemia over the preceding two years, no abdominal pain and mass. An upper gastrointestinal endoscopy revealed some small polyps in the stomach and multiple sessile polyps in the second part of the duodenum, but colonoscopy exam did not reveal any lesion. INTERVENTIONS: A double polypectomy and duodenum segmentary resection with end-to-end anastomosis was performed. Histopathology of the resected duodenum polyps indicated it to be a typical hamartomatous polyp. OUTCOMES: The child was under regular follow-up and recovered well. LESSONS: In this case, the patient was characteristic with pigmentations on his lips and intermittent upper intestinal obstruction (due to mass duodenal polyps), there are no definitive guidelines for the treatment to duodenal PJS hamartomatous polyp, each case requires tailor-made management.

Diagnosis and treatment of pediatric benign pneumoperitoneum: A case report series of 9 patients.

INTRODUCTION: Benign pneumoperitoneum (BPPT) is defined as asymptomatic free intraabdominal air or as pneumoperitoneum without peritonitis. Symptomatic free air requires surgical anagement, but management of asymptomatic pneumoperitoneum is controversial. In this study, we investigate the diagnosis and treatment of BPPT in children. CLINICAL FINDINGS: The clinical data of 9 pediatric patients with BPPT who were admitted to our hospital from January 2000 to January 2015 were retrospectively analyzed to summarize the diagnosis and treatment. Overall, 9 cases were included with 8 males and 1 female, aged from 4 days to 4 years. Among them there were 6 newborns (including 1 premature infant). Patients were all admitted to hospital with the major clinical symptom of abdominal distension, including 2 cases accompanied by tachypnea, 2 cases with vomiting, 1 case with diarrhea, and 2 cases with fever. No previous constipation or obstructive defecation existed. Six newborns had meconium defecation within 24 hours after birth. Physical examination revealed all patients with relaxed abdominal wall except 1 patient with abdominal distension had slight muscle stiffness and hyperactive bowel sounds. Abdominal X-ray suggested free air under the diaphragm in all cases. INTERVENTIONS/OUTCOMES: All patients except for one case of laparotomy were conservatively treated and cured with fasting, infection prevention, rehydration, abdominocentesis, and close observation. Nine cases of patients were all discharged with no death occurrence. After discharge follow-up of 7 months to 6 years was conducted. There was no recurrence of similar symptoms, and children were in good growth and development. CONCLUSION: The diagnosis of BPPT mainly relies on clinical symptoms in patient, careful abdominal examination, abdominal X-ray combined with abdominocentesis, and the exclusion of gastrointestinal perforation for confirmation. Conservative treatment can cure the disease. Attention should be paid to distinguish with surgical pneumoperitoneum to avoid unnecessary surgical exploration.
