Is excision of a choledochal cyst in the neonatal period necessary?

Purpose

Although the incidence of choledochal cyst (CC) diagnosed in the prenatal or neonatal period is increasing, excision of CC in early infancy is not universally recommended. To validate the rationale of excision of CC in the neonatal period, operative complications and the histologic grade of liver fibrosis at the time of excision of CC were compared in three age groups.

Methods

198 patients who underwent excision of CC, were divided into three age groups, i.e., within 30 days old (group 1, n = 11), 1 to 12 month-old (group 2, n = 40) and over 12 month-old (group 2, n = 147). Retrospective review of their medical records was performed.

Results

The overall operative complications were 12 (7 cholangitis, 4 bleeding, 1 ileus). No complication occurred in the group 1. The grade of liver fibrosis had statistically significant positive correlation among groups.

Conclusion

Excision of CC in the neonatal period is a safe procedure. The grade of liver fibrosis increased with age. These results support the rationale of early excision of CC.     

Intrahepatic cholangiocarcinoma arising 28 years after excision of a type IV-A congenital choledochal cyst: report of a case

This report presents a rare case of intrahepatic cholangiocarcinoma (IHCC) arising 28 years after excision of a type IV-A congenital choledochal cyst. The patient underwent excision of a congenital choledochal cyst (Todani’s type IV-A) at 12 years of age, with Roux-en-Y hepaticojejunostomy reconstruction. She received a pancreaticoduodenectomy (PD) using the modified Child method for an infection of a residual congenital choledochal cyst in the pancreatic head at the age of 18. She was referred to this department with a liver tumor 22 years later. Left hemihepatectomy with left-side caudate lobectomy was performed and the tumor was pathologically diagnosed to be IHCC. The cause of the current carcinogenesis was presumed to be reflux of pancreatic juice into the residual intrahepatic bile duct during surgery. This case suggests that a careful long-term follow-up is important for patients with congenital choledochal cysts, even if a separation-operation was performed at a young age, and especially after PD.     

An uncommon presentation of hydatid cyst in submandibular salivary gland—a case report

Hydatid disease is a parasitosis known as hydatidosis or echinococcosis. It affects both animals and humans. Hydatid cyst of the head and neck region is uncommon and the involvement of salivary glands, especially the submandibular gland is very rare. A case of submandibular gland hydatid cyst is reported in this article. A patient presented with a swelling of submandibular region since 8 months. On examination, swelling revealed a soft, non-tender, mobile mass with fluctuation positive when done bimanually measuring 8 × 6 cm. Chest X-ray and abdominal ultrasonography were normal. Excision of the submandibular gland with the mass was performed and pathological examination confirmed the swelling to be a hydatid cyst of the right submandibular gland.     

Castleman’s disease of the mesorectum: Report of a case

Castleman’s disease is a benign lymphoid proliferative disorder, which most commonly presents as a solitary mass in the mediastinum, although extrathoracic sites have been reported in the neck, axilla, pelvis, mesentery, pancreas, and retroperitoneum. We report a case of asymptomatic, isolated Castleman’s disease in the mesorectum, which is extremely rare. The patient was a 34-year-old woman who underwent investigations for vaginal spotting. A presacral mass was located on the left side of the rectum, 10 cm from the anal verge. Contrast-enhanced computed tomography showed a large, well-demarcated, strongly enhancing mass with internal radiating septa in the mesorectum. The mass was well circumscribed and isointense to muscle on T1-weighted magnetic resonance imaging, appearing as a slightly hyperintense mass on T2-weighted imaging. We performed laparoscopic mesorectal mass excision, and histological examination revealed features typical of the hyaline-vascular type of Castleman’s disease. Thus, when a mesorectal mass is being investigated, Castleman’s disease should be considered in the differential diagnosis.

Detection of Mirizzi syndrome with magnetic resonance cholangiopancreatography: laparoscopic or open approach?

Imaging of the gallbladder and biliary tract has changed dramatically in the past 20 years. Magnetic resonancecholangiopancreatography provides a noninvasive alternative to endoscopic retrograde cholangiopancreatography and percutaneous transhepatic cholangiography in the diagnosis of Mirizzi syndrome. In this laparoscopic era, when diagnosis is certain, surgeons must choose between a laparoscopic and a traditional open approach. The authors review their cases of hepatobiliary surgery during the period 1993-2000. Three cases of Mirizzi syndrome (0.4%) were observed among 712 surgical hepatobiliary patients (two type 1 cases and one type 2 case). The authors suggest that with Mirizzi syndrome type 1, laparoscopy together with peroperative cholangiography should be used to resolve anatomic doubts. If clipping of the cystic duct is possible and certain, then laparoscopy may be continued and finished. In the case of cholecystocholedochal fistula (Mirizzi syndrome type 2), when the diagnosis is determined before surgery, the authors believe that laparoscopy is dangerous. Adhesions, inflammation, and anatomy changes may cause injuries to the main bile duct, so an open traditional approach is suggested.     

An unusual case of exclusive liver metastases from adenoid cystic carcinoma of the submandibular gland: a role for surgery? Report of a case

Adenoid cystic carcinoma (ACC) is a relatively rare tumor of the salivary glands, accounting for approximately 5%–10% of all salivary gland tumors. An important feature of ACCs is the long clinical course with a high rate of distant metastases, with an incidence of more than 40% for ACC of submandibular glands. The preferential sites of metastases are the lung and bone, followed by the brain and liver. Most liver metastases are derived from nonparotid ACCs, and the presentation is often related to local recurrence or metastases to other organs. We herein report the case of a patient with liver metastases treated by a hepatectomy, which occurred 18 months after the primary resection of an ACC of the submandibular gland. We furthermore review the literature concerning the management of these tumors.     

Giant sublingual epidermoid cyst — An unusual case report

Epidermoid cysts of the floor of the mouth represent <0.01% of all oral cysts. Only few cases have been reported so far. We report a case of a 24 years man with a large sublingual swelling for 17 years, unable to take solid meals. The swelling was approximately 13 × 13 cm, non-tender, non-transilluminant, with doughy consistency and with patent visible Wharton’s duct openings on both the sides. Initial decompression of the lesion was done to facilitate nasotracheal intubation followed by partial excision of the cyst with marsupialization. Histopathological examination revealed a thick wall cyst lined with pseudostratified squamous epithelium without any evidence of dermal appendages suggestive of epidermoid cyst. Postoperative care included extraction of the loose infected dentures and physiotherapy of the ankylosed temporomandibular joints. Clinical progress was uneventful and cosmetic appearance was acceptable on 6 month and 2 years follow up with normal mastication function.     

Unintentional ileostomy: a complication of the videolaparoscopic method? Report of the first case

Jejunostomy is widely acknowledged in the literature as a means for enteral nutrition. Complication rates range from 16% to 46% for the classical open technique and from 11% to 70% for the several mini-invasive techniques currently in use, including the laparoscopic techniques. The most probable complications are abscess, intestinal obstruction, abdominal wall infection, intraperitoneal leakage, enterocutaneous fistula, and loss, elbowing, or even rupture of the enteral probe. The authors report the case of a patient with severe malnutrition concomitant with advanced gastric cancer who underwent jejunostomy because of an incapacity for normal oral feeding. Previous attempts to pass a nasal enteral probe were not successful, even with the aid of endoscopy. Videolaparoscopy was indicated for adequate staging of the neoplasm and for performance of video-assisted jejunostomy. During the procedure, an extensive carcinomatous process was observed that rendered comprehension of the abdominal anatomy extremely difficult. Consequently, while attempting jejunal catheterization, unintentional catheterization of the terminal ileum took place. The authors discuss this first reported case of unintentional ileostomy and review the literature.     

Anomalous union of the pancreaticobiliary duct without choledochal cyst: is cholecystectomy alone sufficient?

Purpose

Anomalous union of the pancreaticobiliary duct (AUPBD) is frequently associated with choledochal cyst and biliary tract cancers. Management of AUPBD with choledochal cyst consists of extrahepatic bile duct excision and cholecystectomy. In cases of AUPBD without choledochal cyst, cholecystectomy alone is usually recommended. This study aimed to evaluate the occurrence of biliary tract cancer in AUPBD patients in order to assess the validity of the currently recommended operative management.

Methods

Of a total of 10,255 endoscopic retrograde cholangiopancreatography cases performed at two Korea University hospitals from 2001 to 2010, 55 (0.54 %) cases of AUPBD were identified. Patients with AUPBD were divided according to its subtype (P-C union and C-P union) and the presence of choledochal cyst for analysis. The occurrence of benign and malignant disease was evaluated and compared between the groups.

Results

Gallbladder stones were more frequently found in AUPBD patients without choledochal cyst (p?=?0.032). Biliary tract cancer occurred more frequently in P-C union (p?=?0.050), especially the common bile duct cancer (p?=?0.023). When analyzed according to the presence of choledochal cyst, biliary tract cancer occurred more frequently in AUPBD patients without choledochal cyst (p?=?0.005), with bile duct cancer being significantly more common (p?=?0.015). However, there was no difference in the presence of gallbladder cancer between the two groups (p?=?0.318).

Conclusions

Since cancers of the biliary tract occur more frequently in the AUPBD group without choledochal cyst, cholecystectomy alone may not be protective of the future occurrence of bile duct cancers, and thus, vigilant surveillance is necessary in this population group.     

Contralateral fracture of the penis with concomitant urethral injury — Report of a rare case

Penile refracture is a rare urological emergency, more so on the side contralateral to the previous fracture. A 55-year-old male was referred 70 hours after sudden detumescence during sexual intercourse, with a history of blood at the urethral meatus. The patient had had a fracture of the penis four years previously. Examination revealed ecchymosis and swelling of the proximal shaft and purulent discharge from a laceration in the penile skin over the proximal corpora. Ultrasonography revealed laceration of the right tunica albuginea and corpus cavernosum. Exploration revealed scar tissue at the site of the previous operation on the left side and a fresh laceration, 1cm in size, in the right corpus cavernosum in the mid shaft, and a urethral defect of 0.5 cm. The patient had normal erections post-operatively and no complications at 6 months follow-up. On literature review, anecdotal cases of contralateral refracture of the penis were found. High suspicion, prompt diagnosis and expedient surgical management are essential for a good outcome with minimal complications.     

Enlarging lymphoepithelial cyst of the pancreas during 12 months of observation: report of a case

Pancreatic lymphoepithelial cysts (LECs) are rare benign pancreatic cystic lesions, the etiology of which is unknown. We report a case of a pancreatic LEC, discovered incidentally in a 63-year-old man during a follow-up clinic visit for an abdominal aneurysm. Computed tomography showed a multilocular cyst, 60-mm diameter in the body of the pancreas. This cyst increased from 6.0 to 6.5 cm during 12 months of observation. Part of the cyst was also visualized on positron emission tomography imaging. Since a pancreatic cystic neoplasm could not be ruled out, we performed distal pancreatectomy and postoperative pathological examination confirmed that the lesion was an LEC of the pancreas. Despite the conclusive postoperative findings, resection is unavoidable when a true pancreatic neoplasm cannot be excluded.

Ectopic hamartomatous thymoma — A truly rare neoplasm: Report of a case

An ectopic hamartomatous thymoma is an extremely rare benign neoplasm that commonly occurs in the lower neck region. It has distinctive pathological features that include haphazardly arranged spindle cells, epithelial cells, and mature fat tissue. Its histogenesis is still controversial. This report presents a case of a 26-year-old man with ectopic hamartomatous thymoma in the left supraclavicular region, and discusses the current knowledge regarding this type of lesion. Clinicians as well as pathologists should be aware of the existence of this disease so that it can be identified correctly.     

Spontaneous resolution of symptoms associated with a facet synovial cyst in an adult female – a case report

Background:

Facet cysts are implicated in neural compression in the lumbar spine. Surgery is the definitive treatment for symptomatic facet cysts since the failure rate for conservative treatment is quite high; however, the role of physical/manual medicine practitioners in the management of symptomatic facet cysts has not been well explored. This case report will add to the body of evidence of spontaneous resolution of symptoms associated with facet cysts in the chiropractic literature.

Case:

A 58 year old female presented with acute low back and right leg pain which she attributed to a series of exercise classes that involved frequent foot stomping. Physical examination did not elicit any objective evidence of radiculopathy but MRI and CT scans revealed a facet cyst impinging on the right L5 nerve root. Injections and surgery were recommended; however, the patient’s radicular symptoms completely resolved after three months without surgical intervention.

Summary:

There is currently a paucity of data in the literature regarding the chiropractor’s role in the management of symptomatic facet cysts. The case presented here has added to this literature and possible areas for future research have been explored.     

Meckel’s diverticulum perforation: Report of a case and review of the literature

Meckel’s diverticulum is the most common congenital anomaly of the small bowel. The majority of patients with this anomaly will remain asymptomatic; however, several complications can occur, including diverticulitis, haemorrhage, obstruction, intussusception, and perforation. A 39-year-old man was admitted to the emergency department after complaining of abdominal pain for the past few days. Upon worsening of his clinical status and after completing the diagnostic workup, he was taken to the operating theatre where he was found to have faecal peritonitis due to perforated Meckel’s diverticulum. Although it might be difficult to diagnose Meckel’s diverticulum pathology preoperatively, it should always be sought and identified during a laparotomy for acute abdomen in order to exclude the increased morbidities resulting from its complications.     

Urothelial carcinoma arising within bladder diverticulum—Report of a case and review of the literature

Bladder diverticulum is an outpouching of bladder mucosa through the musculature of the bladder wall. The incidence of bladder diverticulum in Taiwan is about 1.7% in children and 23.4% in adults. Intradiverticular carcinoma of urinary bladder is uncommon. It ranges from 0.8% to 14.3%. Here we report a case of urothelial carcinoma within a bladder diverticulum. A 60-year-old male patient had history of BPH under medical treatment and right ureteral stone treated with extracorporeal shock wave lithotripsy (ESWL). He presented with painless gross hematuria about 3 months after ESWL. Intravenous pyelography showed a filling defect within the bladder diverticulum. Histopathological diagnosis of low grade urothelial carcinoma arising from the bladder diverticulum was made following cystoscopic biopsy. Laparoscopic partial cystectomy was performed with subsequent intravesical chemotherapy. Tumor recurrence was found not from the previous diverticulum but from another area during regular cystoscopy at the 6-month postoperative follow up. He underwent transurethral resection of bladder tumor. Pathology revealed a noninvasive, high grade urothelial carcinoma. There was no further bladder tumor recurrence during the 1-year follow-up period. Bladder-sparing surgery with close cystoscopy follow up for intradiverticular urothelial carcinoma can be applied as an alternative treatment modality.     

Adenocarcinoma arising from an anal gland—Report of a case

INTRODUCTIONAdenocarcinoma arising from an anal gland is extremely rare. Most anal canal cancers are squamous cell carcinoma, and adenocarcinoma is infrequently diagnosed. Diagnostic criteria and the standard treatment for adenocarcinoma of the anal canal have not been clearly defined, in part because of the rarity of this lesion.PRESENTATION OF CASEAn 84-year-old man who presented with a piece of tissue prolapsing from the anus. An incisional biopsy showed adenocarcinoma, and an abdomino-perineal resection was then performed. Cytokeratin 7 (CK7), cytokeratin 19 (CK19) stained positive in the specimen, suggesting that the tumor developed from an anal gland. The patient was discharged after surgery without any complications.DISCUSSIONExact diagnostic criteria for adenocarcinoma of the anal canal have not been previously described. In the present case, CK7 and CK19 were stained, and the tumor showed positivity for both of these markers, which is compatible with the staining patterns of anal gland origin cancer. Radical resection is recommended rather than local resection, because of the tumor's high recurrence rate. Some authors recommend combined modality treatment with preoperative or postoperative chemoradiotherapy because of the high rate of distant recurrence.CONCLUSIONThe preoperative diagnosis of adenocarcinoma arising from an anal gland is not easily established. However, it may be possible to suspect an anal glandular adenocarcinoma based on a meticulous physical examination, appropriate diagnostic studies and pathological findings on biopsy.     

Giant arteriovenous malformation located on the chest wall — Diagnosis and endovascular treatment: Report of a case

Congenital arteriovenous malformations are usually found in the lower extremities, but a chest wall location is extremely rare. Extensive vascular malformations present difficulties for patients because of severe unsightliness and life-threatening bleeding. Surgical planning and therapeutic indications in vascular malformations are still a difficult problem. This report describes the case of a 27-year-old woman with a congenital giant arteriovenous malformation of the left chest wall. Preoperative embolization was planned prior to surgical intervention because of the increased risk of massive bleeding, and the malformation was completely embolized with absolute alcohol.
