Thoracoabdominal foregut duplication cyst with respiratory epithelium and alimentary epithelium

Thoracoabdominal foregut duplication is a rare congenital abnormality. The authors report a case of thoracoabdominal foregut duplication cyst in a 13-year-old male patient. The pathologic report revealed that a thoracic mass with a pseudostratified, ciliated, columnar epithelial lining (respiratory tract epithelium), an abdominal mass with gastric mucosa (alimentary tract epithelium), and the cyst originated from the foregut.     

A rare case of completely isolated duplication cyst of the alimentary tract.

A rare case of a gastrointestinal cystic duplication in a 7-day-old infant is described. The duplication diagnosed antenataly at 25 weeks of gestation was found during surgery to be separated from the gastrointestinal tract, hanging on a vascular pedicle, with no connection to the mesentery. The duplication was excised, and postoperative follow-up of 14 months was uneventful. The possible pathogenesis of this malformation is discussed.

微创法重睑成形术

传统的切开法重睑术中多将重睑设计线下的皮肤、皮下及眼轮匝肌等组织一并切开,切口下垂直切口方向的皮下静脉血管不可避免的将被损伤,术中出血多,组织损伤大,是术后上睑肿胀的主要原因。术者在行切开法重睑术中,用显微外科手术器械及显微外科手术操作技术,术中保留垂直切口方向的皮下较粗的静脉血管,保护切口下缘皮肤真皮下血管网的完整,较好地弥补了传统切开法重睑术的上述缺点。     

Prophylactic intraperitoneal povidone-iodine in alimentary tract surgery

In controlled experiments intraperitoneal povidone-iodine significantly reduced the mortality of mice (p < 0.01) and rats (p < 0.01) with induced peritonitis. Povidone-iodine irrigation of the rat colon before and after anastomosis did not interfere with healing or inhibit peritoneal adhesion formation. However, a newly formulated povidone-iodine solution containing increased PVP significantly reduced adhesion formation in a controlled study in rats.     

Renal teratoma with duplication of cecum and appendix

Renal teratoma is a very rare condition. We report a case of mature renal teratoma in a 1-month-old male infant. The patient was admitted with a right-sided abdominal mass. The mass was found to arise from the right kidney. The tumor was removed successfully, and the patient had an uneventful recovery. The tumor mass also had an appendix and cecum within the tumor, along with a normal appendix and cecum with a separate blood supply.

A rare presentation of Y-duplication of the pancreatic tail with enteric duplication cyst as intussusception in a child: A case report

We report a case of a 2-year-old girl who presented to us with complaints of pain abdomen and non-bilious vomiting. USG was suggestive of intussusception with necrotic bowel and free fluid in the left lumbar region. Operative findings were of enteric duplication cyst of the pancreas which was later confirmed on histopathology. Enteric duplication cysts can occur anywhere in the gastrointestinal tract but duplication cyst within the pancreas is rare. The most common presentation in other reported cases is pain abdomen due to pancreatitis but in our case, we had findings of intussusception. Children usually present with a severe complication like perforation of duplication cyst as in our case. Excision of the cyst and the duplicated pancreatic tail is the mainstay of treatment.     

Direct duplication of the Y chromosome with normal phenotype – incidental finding in two cases

Structural rearrangement in the Y chromosome is closely involved in spermatogenesis. However, several Y chromosome variants may have no deleterious effects on male reproduction. Here, we report two cases of Y chromosomal duplication from incidental findings. Their FISH analysis revealed direct duplication of large segments of short and long arms of the Y chromosome. Nearly two intact Y chromosomes were carried in these two cases with normal phenotype.     

Pancreatitis because of foregut duplication cyst of the pancreas treated by laparoscopic resection

We report a rare case of a foregut duplication cyst of the pancreas containing respiratory epithelium in a healthy adolescent male who presented with recurrent abdominal pain secondary to pancreatitis. The abnormality was revealed on computed tomography performed to evaluate severe abdominal pain radiating to the back. Further imaging (ultrasound and magnetic resonance imaging) confirmed that the lesion was a cyst with no apparent pancreatic ductal communication. Elective laparoscopic resection of the cyst was performed with complete resolution of the patient's symptoms.     

A case of completely isolated advanced enteric duplication cyst cancer performed partial pancreatectomy

IntroductionEnteric duplication cysts are rare and, in addition, isolated enteric duplication cysts are lower morbidity prevalence rate. These cysts lack a connection to the gastrointestinal tract or the adjacent mesenteric vasculature and have only been reported in 10 case reports. In these reports, only two reports were cases with malignant transformation. Our case was a report for the advanced cancer of the isolated enteric duplication cyst.Case presentationThe patient was a 43 year-old woman with slightly abdominal pain and mass formation. The abdominal contrast-enhanced computed tomography showed 130 × 100 × 90 mm huge cystic mass existed in right upper peritoneal cavity. The cystic mass had thickened wall and many enhanced nodules. As these imaging findings suggested a tumor originated from pancreas and the preoperative diagnose was suspect of mucinous cystic neoplasm. In operative findings, the tumor originated from pancreatic head and did not attach to gastrointestinal tract. Final pathology indicated the cyst was an isolated advanced enteric duplication cyst cancer and not originated from pancreas.ConclusionWe experienced an extremely rare case of completely isolated advanced enteric duplication cyst cancer. Unique to this case, the preoperative diagnosis was suspect of mucinous cystic neoplasm arising from pancreas head and partial pancreatectomy was performed. However, in the pathological findings, this cyst diagnosed advanced enteric duplication cyst cancer.     

Laparoscopic treatment of an adult gastric duplication cyst

We hereby report the case of a 24 years old woman with an adult gastric duplication cyst, a very rare congenital disease. Diagnosis was established on preoperative imaging tests. Complete resection of the duplication cyst was undertaken laparoscopically. To the best of our knowledge, this is the first report of laparoscopic resection of an adult gastric duplication cyst.     

Cystic Duplication of the Cecum with Segmental Dilatation of the Ileum: Report of a Case

Duplication cyst and segmental dilatation are rare congenital anomalies of the gastrointestinal tract, both of which are known to result in intestinal obstruction. We describe herein a case of intestinal obstruction in a neonate, caused by a duplication cyst in the cecum. A small dilated segment of ileum was also present at the site where Meckel's diverticulum would be expected, which was not causing obstruction to the luminal contents. Although it is well known that either of these conditions may coexist with a number of congenital malformations, their concurrent occurrence has never been reported before.

Excision of esophageal duplication cysts with robotic-assisted thoracoscopic surgery

Esophageal duplication cysts are infrequent anomalies of the gastrointestinal tract that are predominantly found in children. The conventional surgical approach for removal of these cysts is an open surgery one with a posterolateral thoracotomy incision. However, more recently, these cysts have been excised via video-assisted thoracoscopic surgery (VATS). In this article, we present 2 pediatric patients treated with successful excision of an esophageal duplication cyst via robotic-assisted thoracoscopic surgery (RATS) using the da Vinci surgical system. With robotic technology, precise dissection and complete resection of the thoracic mass was achieved without violating the esophageal mucosa. There were no complications, and the patients did not require placement of a postoperative chest tube. Pathological examination of the mass was consistent with an esophageal (foregut) duplication cyst in both cases.     

Enteric duplication cyst of the pancreas with duplicated pancreatic duct

Enteric duplication cyst is one of the rarest forms of cystic lesion of the pancreas. We report a unique case of an enteric duplication cyst of the pancreas that was communicating with a duplicated pancreatic duct. A 7-year-old girl with severe acute abdominal pain was found to have a large cyst that was smoothly communicating with the dilated pancreatic duct in the pancreatic tail. Analysis of cyst fluid showed elevated levels of amylase, carcinoembryonic antigen (CEA) and CA 19-9, and no epithelial cells. Intraoperative cyst pancreatography revealed that the pancreatic duct was duplicated in the tail: 1 duct was communicating with the cyst, and the other was dilated within the pancreatic tail. The patient underwent spleen-preserving distal pancreatectomy and complete cyst excision without complication. Because preoperative diagnosis of duplication cyst of the pancreas is difficult, this condition should be considered during differential diagnosis of atypical cystic lesions of the pancreas. Complete excision is desirable for the management of duplication cyst of the pancreas.     

Rare craniofacial clefts with duplication of alveolar arch

Summary A 16 year old girl presented with Tessier's No. 4 cleft on the right side coupled with No. 7 and No. 3 cleft on the left. Associated with this she had 6 molars in the left maxillary segment and a 7th unerupted one lying horizontally. Such a unique congenital anomaly has not been reported in literature until now.
