Nonhypertrophic Pyloric Stenosis in a Neonate: A Rare Presentation

Gastric outlet obstruction in neonates due to nonhypertrophic pyloric stenosis (NHPS) is a rare cause. We report the case of a 37-day-old baby boy who presented with complaints of vomiting for the last 2 weeks and an inconsolable cry over the last 2 days. He has been vomiting seven to eight times a day, a few hours after breastfeeding. On ultrasonography, the stomach was distended, while the pylorus was not hypertrophied. An upper gastrointestinal (GI) contrast study was done, which was suggestive of gastric volvulus. We performed a laparoscopy for the same. Intraoperatively, the volvulus was already resolved. We performed gastropexy. Postoperatively, he had persistent symptoms, for which an upper GI endoscopy was performed. It demonstrated a narrow pylorus, consistent with the NHPS. We performed a laparoscopic Heineke-Mikulicz pyloroplasty. The patient's symptoms had improved postoperatively. He was discharged after 5 days.

Endoscopic Treatment for Nonhypertrophic Idiopathic Pyloric Stenosis in an Adolescent Patient

Nonhypertrophic idiopathic pyloric stenosis (NHIPS) is a rare occurrence in children. It could be related to peptic ulcers, but a definitive cause is yet to be found. Treatment is a matter of debate, ranging from medical to surgical. We report the case of a 15-year-old boy suffering postprandial vomiting and weight loss in the previous 3 months. NHIPS was diagnosed and successfully treated with several sessions of endoscopic pyloric dilation and jejunal feeding. In association with a multidisciplinary approach, endoscopic dilation should be considered as a first-line treatment to avoid surgery.

Uncommon Cause of Chronic Vomiting in Children

Gastric outlet obstruction (GOO) is unusual and must be suspected in children with chronic vomiting and abnormal weight status. The treatment depends on etiology, and surgery is not always the first remedy. Diagnosis is easily confirmed by upper gastrointestinal fibroscopy.We report the case of an 11-year-old girl, who was presented with non-bilious emesis and weight loss. Abdominal computed tomography, ultrasound, and upper gastrointestinal fibroscopy showed dilated stomach with pyloric stenosis, which was confirmed by abdominal laparoscopic exploration and cured by Heineke-Mikulicz pyloroplasty. We also compare our study to previously reported cases.

Hypertrophic pyloric stenosis in an older child: a rare presentation with successful standard surgical management

Infantile hypertrophic pyloric stenosis is a disease of neonatal period usually manifest between the third and fourth weeks of life. Metabolic alkalosis and paradoxical aciduria are two common sequel of this entity. We report an unusual case of an 8-year-old boy who presented with recurrent, long-standing episodes of non-bilious vomiting and poor weight gain without any other metabolic derangement.

Gastric outlet obstruction in children: an overview with report of Jodhpur disease and Sharma's classification

BACKGROUND/PURPOSE

Gastric outlet obstruction (GOO) is overwhelmingly described as infantile hypertrophic pyloric stenosis that overshadows other causes; thereby, there is a need to develop an elaborate and comprehensive classification. We present the same and establish a new disease called primary acquired gastric outlet obstruction during infancy and childhood that was reported for the first time by us in 1997, reviewing the literature published since then, with report of our new cases.

METHODS

Eight patients of this disease presented at our center from 1996 to May 2008, and these were analyzed epidemiologically and clinically. Other reports published in literature were compared, and all reported patients were compiled.

RESULTS

All 8 cases presented at age ranging from 1 month to 6 years, with mean age of 2.9 years; there was predilection for male sex (male, 7; female, 1). Presenting symptoms and signs were nonbilious vomiting, weight loss, dehydration, dyselectrolytemia, abdominal pain, and visible gastric peristalsis. Upper gastrointestinal contrast study showed large stomach and increased gastric emptying time. Endoscopy displayed normal stomach without intraluminal lesion. Exploration revealed a dilated stomach, without any pyloric muscular hypertrophy, scarring, inflammation, or obstruction externally or intraluminally. Result of histopathologic examination was normal. All patients except 1 (died of unrelated cause) were cured by Heineke-Mikulicz pyloroplasty.

CONCLUSIONS

These patients represent a new disease entity designated as primary acquired gastric outlet obstruction during infancy and childhood. Author's classification is complete and scientific, encompassing all rare causes of GOO. We nickname this idiopathic variety of GOO the Jodhpur disease, the place of the first cases.
