Surgical options include open, laparoscopic and robotic approaches. However, Heller's myotomy remains the treatment of choice. This report describes our experience with robot-assisted Heller's myotomy in children and presents a review of the literature. Methods: Included in this study are children who underwent robot-assisted Heller's myotomy for esophageal achalasia via the Da Vinci surgical system between 2004 and 2015 at King Saud University Medical City, Riyadh, Saudi Arabia. The medical records of these patients were reviewed for demographic data, presenting symptoms, diagnostic modalities, operative procedures, complications, outcomes and follow-ups. Results: Six patients were identified. The age of the patients at surgery ranged between 2 and 12 years (mean 7.1 years). The most common presenting symptoms were dysphagia, vomiting and nocturnal cough. Contrast swallow and upper gastrointestinal endoscopy established a diagnosis of esophageal achalasia in all of the patients. Four patients underwent esophageal dilatation 2-5 times before the definitive procedure. All patients underwent successful robot-assisted Heller's myotomy with concomitant partial posterior fundoplication. The postoperative course was uneventful. Five patients had a complete resolution of the symptoms and one patient improved. The follow-up assessments have been consistent and have ranged from 0.5 to 11 years (mean 4.4 years). Conclusion: Robotic-assisted Heller's myotomy for esophageal achalasia in children is safe and effective and is a suitable alternative to open and laparoscopic approaches.

The majority of EFBs pass harmlessly through the gastrointestinal tract; however, some EFBs can cause significant morbidities. This study was conducted to review our experience in managing esophageal foreign bodies in pediatric patients, with an emphasis on the management and outcomes of complicated cases. Methods: Between March 1995 and March 2013, the records of all children up to the age of 12 years who were admitted to King Khalid University Hospital, Riyadh, Saudi Arabia, with a final diagnosis of EFBs were reviewed. The medical records were analyzed with respect to demographic data, presenting symptoms, workup investigation, management, complications, and outcomes. Results: Seventy patients were identified (38 boys and 32 girls). The ages ranged from 5 days to 12 years (mean: 4.4 years). Fifty-three (75.7%) patients presented within 24 hours. Thirteen (18.6%) patients had underlying predisposing factors. The most common EFB, found in 30 (42.8%) patients, was a coin. Witnessed ingestion of a FB was documented in 52 (74.2%) patients. The most common symptoms were drooling of saliva in 42 (60%) patients, followed by vomiting in 36 (51.4%) patients. Four (5.7%) patients presented with complications secondary to FB impaction, including hypopharyngeal wall perforation, acquired esophageobronchial fistula, localized esophageal perforation with inflammation, and perforation with stricture formation. The follow-up period ranged from 2 to 12 months, and all patients had complete recovery without any sequelae.

These are generally benign tumors, which in rare cases have been identified to be associ-ated with multiple para-neoplastic syndromes. Case Report: This is a case of a solitary fibrous tumor of the pleura in a 49 year old female which was found to be associ-ated with elevated levels of serum beta human chorionic gonadotropin (b-hCG). Due to the lack of plausible causes for elevated b-hCG in the patient, immune-histochemical staining of the tumor specimen for b-hCG was obtained. This confirmed the patient’s solitary fibrous tumor as the source of the b-hCG. The patient was also found to have a possible paraneoplastic syndrome with irregular menstruation and hot flushes from the secreted b-hCG. Conclusions: This is the first reported case of solitary fibrous tumors of the pleura producing b-hCG. Multiple types of lung tumors have been associated ...
