Hilar cysts are infrequent post-transplant biliary tract complications. Thirteen cases were discovered among 493 consecutive
liver transplants (2.6 %). Three (0.60 %) were symptomatic (obstructive jaundice) while the other ten were found by systematically
searching in the hilum in a series of 129 consecutive, resected grafts at retransplantation or autopsy (n = 54). Two types of cysts were detected: in eight grafts (1.6 %), these were blind unilocular cavities with viscid mucous
content, located adjacent to the biliary tract anastomoses. These had been inadvertently created as a result of the sequestered
remnant cystic duct after cholecystectomies and biliary tract reconstructions, where a double-barreled common duct and long
cystic duct had been present in the donor liver. These mucoceles ranged from 0.5 to 5.5 cm in diameter (median 1.7 cm). The
three symptomatic cases were diagnosed by imaging techniques 3.5 years after transplantation; however, this type of cyst was
found as early as the 2nd month post-transplantation when detected in lost liver grafts. Five livers (1 %), lost between 5
months and 2.8 years post-transplantation, showed cystically dilated peribiliary glands, sometimes with multilocular, and
occasionally multiple, cavities ranging from 0.5 to 2 cm in diameter (median 0.8 cm). This type of cyst was asymptomatic and
located adjacent to the left, right, or common hepatic ducts. Threads were found near four cysts, suggesting that surgical
injury may have been responsible for obstructing the neck of the glands. With the increasing number of long-term survivors
of liver transplantation, unless preventive surgical methods are implemented, the number of symptomatic cysts of these origins
can be expected to grow. Transplantation teams should, therefore, be aware of these potential causes of biliary tract complications.

Bone islands and juxta-articular bone cysts are relatively common incidental findings when X-rays are taken for other purposes. We have identified that the incidence of bone islands in the hands of asymptomatic children between the ages of 5 and 13 years is 3.8% and the incidence of cysts in the same population is 2.8%. Bone islands were most common in the scaphoid, whilst juxta-articular bone cysts were most common in the capitate. The age at which they appear has not been reported previously. This study first identifies their presence in the hands of children of age 10 years and 2 months (bone islands) and 10 years 0 months (juxta-articular bone cysts). Most of the lesions were already present on the first radiograph taken. New bone islands appeared in five cases between the ages of 13 years and 1 month and 15 years and 3 months. New juxta-articular bone cysts were observed to appear in five cases between the ages of 10 years 10 months and 15 years 0 months. No island or cyst changed in size during the review period. 相似文献

Oral cysticercosis: a collaborative study of 16 cases. 总被引:1,自引:0,他引:1
Wilson A Delgado-Aza?ero Adalberto Mosqueda-Taylor Roman Carlos-Bregni Ruben Del Muro-Delgado Marco Antonio Díaz-Franco Elisa Contreras-Vidaurre 《Oral surgery, oral medicine, oral pathology, oral radiology, and endodontics》2007,103(4):528-533
Cysticercosis is a potentially fatal parasitic disease that rarely involves the oral region in humans. This study includes 21 lesions seen in 16 Latin American patients. There were 8 men and 8 women, with an age range from 6 to 67 years (mean 33.6 years). Most cases appeared as asymptomatic submucosal nodules that resembled mucous cysts or benign mesenchymal neoplasms. Most were found in the tongue (11 cases), followed by buccal mucosa and the lower lip (4 cases each) and upper lip (2 cases). These were well circumscribed, and ranged in size from 1 to 2.5 cm in diameter. Typical histologic features of viable cysticerci were observed in 15 cases, and the presence of colloid degeneration and granular mineralization were detected in only 1 case. In all cases, simple surgical excision was sufficient to ensure complete removal of the lesions without postoperative complications. It is important to carry out a detailed study in every case, in order to exclude the presence of the parasite in other sites. 相似文献

The outcome of surgically treated mucous cysts of the foot is poorly documented in the orthopaedic literature. This study reports on the treatment of mucous cysts of the toes by simple excision and joint debridement. This is in contrast to treatment of similar lesions in the fingers which is often treated by excision of the cyst, joint debridement, and rotational flap. Following this procedure on 15 patients (15 cysts), at a minimum of 2 years postoperatively, only one cyst had recurred at 9 months. All patients were satisfied by the cosmetic appearance of their toe. The authors reviewed the available literature on this condition and suggest that this method of treatment provides good functional and cosmetic results with a minimal rate of recurrence. 相似文献

A study of 28 patients with mucoid cysts of the penile skin is reported. The lesions were seldom diagnosed correctly, either clinically or pathologically. The distinctive histologic features of the cysts include a lining of stratified columnar epithelium, often associated with intra-epithelial mucous cells and/or mucous glands. These cysts most likely arise from ectopic urethral mucosa sequestered in the penile skin during embryologic development. 相似文献

HYPOTHESIS: Clinical presentation of appendiceal mucocele is related to malignancy and can influence surgical approach. DESIGN: Retrospective study. SETTING: Tertiary referral center. PATIENTS: All cases of primary appendiceal mucoceles (simple mucocele, cystadenoma, cystadenocarcinoma) diagnosed between 1976 and 2000 were reviewed. There were 135 patients, 74 of whom were female. Mean age at diagnosis was 59 years. Mean follow-up was more than 6 years. INTERVENTIONS: A total of 129 patients underwent surgery, consisting of appendectomy (22 patients), right hemicolectomy (25 patients), or more extensive procedures (82 patients). MAIN OUTCOME MEASURES: Clinical, diagnostic, and surgical variables were statistically compared with postoperative morbidity and mortality and the presence of malignancy. P<.05 was considered significant. RESULTS: The presence of symptoms was associated with malignancy (58% vs 15%, P<.001), particularly abdominal pain (56% vs 29%, P =.005) and weight loss (77% vs 31%, P =.002). Abdominal mass was also associated with malignancy (86% vs 25%, P<.001). Moreover, pseudomyxoma peritonei and mucocele extravasation were associated with malignancy (95% vs 13%, P<.001, and 83% vs 15%, P<.001, respectively). The lesion size was not associated with malignancy; however, cystadenomas were significantly larger than simple mucoceles (8.1 cm vs 4.1 cm, P<.001), and no cystadenoma was less than 2 cm in largest diameter. CONCLUSIONS: A number of clinical, diagnostic, and intraoperative findings are associated with malignant mucoceles. All mucoceles greater than 2 cm should be excised to remove premalignant lesions. 相似文献

Mucous cysts formation following a rhinoplasty is a rare complication. Only 16 cases have been reported. The cysts seem to arise from mucosal remnants left in the subcutaneous layer and must be distinguished from other complications causing postoperative swelling of the nose, such as foreign body, paraffinoma and bony or cartilagineous fragments. We describe two cases of dorsal mucous cysts following rhinoplasty, provide a review of the concerning literature and discuss the removal of the lesions by nasal endoscopy. Nasal endoscopy allows excellent exposure of the operative field, without the need of open rhinoplasty technique, allowing fast healing, minor swelling and no external scar. 相似文献

The medium- and long-term results of conservative and surgical treatment of ACL lesions were evaluated by analysis of the current literature. Only reports with a minimum follow-up of 4 years were taken into account. Concerning conservative treatment, the literature search revealed only 7 papers with a total of 636 cases. Reports on the results of surgical treatment were separated into four categories: primary repair, with 13 papers (1205 cases), extraarticular tenodesis, with 4 papers (232 cases), ACL reconstruction, with 26 papers (2693 cases) and ACL prosthetic replacement (reconstruction using synthetics) with 5 papers (370 cases). The mean functional scores show about 70% good and excellent results for all treatment regimens. Clinical laxity persists in almost all conservatively treated cases, in almost half of the cases with primary repair, extra-articular tenodesis, and synthetic substitution, and in almost one-third of the cases with ACL reconstruction. The incidence of secondary ACL surgery was lowest in the conservative group (4.6%), whereas secondary meniscus surgery was lowest in the ACL reconstruction group (3.5%). Compared with the conservative group (12%), surgical treatment evolved to a higher osteoarthritic morbidity. Sports participation was higher in the ACL reconstruction group. This analysis may provide a more realistic view on the outcome of treatment of ACL lesions, and on the relationship between treatment, activity level and osteoarthritis. 相似文献

Epidermoid cysts are malformations that are rarely observed in the oral cavity. Histologically, these cysts may be further classified as epidermoid, dermoid, or teratoid depending on the stratified epithelium. We report the case of an 11-year-old girl who had developed an epidermoid cyst over a period of 4 years, which presented as a soft, painless left-sided sublingual swelling without mucosal lesions. Imaging revealed a cystic formation with a central concrement. The lesion was surgically excised via an intraoral approach and after histological examination was diagnosed as an epidermoid cyst. Differential diagnoses for epidermoid cysts include infections, tumors, mucous extravasation, and sialolithiasis or sialoadenitis of the sublingual gland. If tumors are excised completely recurrence is very rare. In cases of postoperative saliva retention with recurrent inflammation of the salivary gland, submandibulectomy is indicated. 相似文献

The aim of the study was to define the influence of age on the surgical treatment of cancer of the gall bladder. From a population of 731 patients: 104 were over 80 years (14%) and 230 were between 70 ant 80 years (32%). The histological stages T1, T2, T3, T4 were also distributed throughout the various age groups. There were however significantly more in situ lesions before the age of 70 years than after. The incidence of resection was similar in the various age groups but extended right hepatectomy was only carried out in patients under 70 years. The mortality rate was low for patients who underwent surgery for lesions graded Tis, T1 and T2. High survival rates were only obtained in the Tis and T1 patient groups. T2 grade cancers had a significantly improved prognosis when resection was carried out. Duration of survival after bilio-intestinal anastomosis was very short regardless of the age of the patient. In summary, age did not appear to constitute a contraindication to resection for early lesions, but it did have an effect for the lesions graded T1, T2, on the degree of hepatic resection around the gall bladder. Lesions graded Tis were all treated by simple cholecystectomy regardless of age. Patients with T3 or T4 lesions did not benefit from resection, regardless of age, and in these cases the value of bilio-intestinal anastomosis is debatable. 相似文献

Discal cysts are rare lesions that can result in refractory sciatica. Because they are so rare, their exact origin and details of the clinical manifestations are still unknown. The authors report on five men treated for discal cysts. The mean age of the patients at the time of the surgery was 32 years (range 25-38 years). All patients suffered from lower-extremity pain and the results of the straight leg-raising test were positive in all cases. Three patients reported motor weakness and four had sensory disturbance--symptoms similar to those found in patients with lumbar disc herniation. Magnetic resonance imaging demonstrated spherically shaped extradural lesions of various sizes with low and high signal intensities on T1- and T2-weighted images, respectively. Discography revealed obvious communication between the cyst and the intervertebral disc with reproducible leg pain in all patients. All patients underwent posterior decompression and excision of the cysts either with or without additional discectomy. The radicular symptoms were remarkably improved in all patients immediately after surgery, and no recurrent lesions were noted during follow up. 相似文献

Seventy-three laparoscopic procedures were performed for the treatment of focal lesions of the liver. Fifty-four patients had operations for non-parasitic cysts of the liver and cystic disease. Polycystic disease of the liver was in 8 patients. Multiple cysts were in 19 patients, solitary - in 27. A total of 139 cysts were treated. Surgery was performed with the standard technique. Atypical marginal resection of the liver was performed in 16 patients for hemangioma (n=8), nodular hyperplasia (n=2), hepatic metastases (n=5), hamartoma (n=1). Atypical marginal resection by type of peritumor resection was conducted in 5 cases, and it was similar to segmentectomy in 11 cases. Laparoscopic cryodestruction of benign tumors and hepatic metastases was performed in 3 patients including in combination with atypical marginal resection in 2 cases. There were no intrasurgical complications which required laparotomies. There were no hemotransfusions. Long-term results were followed-up from 1 to 3 years in 25 patients with hepatic cysts and from 3 months to 3 years in 7 patients after marginal resection for hemangiomas and fibronodular hyperplasia. Ultrasonic examination revealed no recurrences of the disease. 相似文献

We analyze the experience in laparoscopic liver surgery in the Department of General Surgery and Liver Transplantation of Fundeni Clinical Institute between september 1998 and march 2003. This study includes 36 patients, 24 females (66.7%) and 12 males (33.3%) with ages between 25 and 67 and a mean age of 46 years. From the group of 36 patients with liver pathology considered for laparoscopic treatment 6 cases had multiple hepatic lesions with no preop diagnosis. The postoperative diagnosis was neoplasia in 4 cases, noncellular necrosis with chronic inflammation in one case and focal nodular hyperplasia in another case. The fenestration and drainage were used as laparoscopic treatment in case of 7 patients with nonparasitic liver cysts. Nine patients from our group had hydatid cysts. In 7 patients the treatment consisted in partial pericystectomy after inactivation and parasite evacuation. In 2 patients an ideal pericystectomy was performed for cysts located in segments II and III. The solid lesions selected for laparoscopic treatment were in 3 cases benign symptomatic tumors with no preoperative diagnosis, in 9 cases symptomatic hemangioma and in 2 cases malignant lesions. From these 14 patients in only 2 cases the lesions were located in the right antero lateral segments. Only in the case of metastasis a left lateral sectorectomy was performed, in all other cases a nonanatomical resection being performed. Conversion to open surgery was necessary in 11.11% of cases (2 hemangioma, 2 partial pericystectomies) for bleeding control. In our study we had no mortality and 11.11% morbidity. The follow-up was available in all patients for a mean time of 18 months (10 to 36). A CT scan was made in all patients with solid lesions 6 months after surgery and an ultrasound examination in all other cases. All patients were nonsymptomatic at repeated reevaluations. We are now at the beginning of laparoscopic liver surgery and these results need to be confirmed. The benefits seem to be those of any miniinvasive surgery: reduced trauma to the abdominal wall, early mobilization, shorter hospital stay, better aesthetics. 相似文献

Juxtaphyseal aneurysmal bone cysts. 总被引:1,自引:0,他引:1
M Rizzo D T Dellaero J M Harrelson S P Scully 《Clinical orthopaedics and related research》1999,(364):205-212
Aneurysmal bone cysts are benign primary or secondary lesions that commonly arise in long bones and often before skeletal maturity. Little has been written about aneurysmal bone cysts that abut the physeal plate. The records of 15 patients with juxtaphyseal aneurysmal bone cysts were reviewed. Fourteen of the patients were referred with abnormal radiographs after evaluation for pain in the affected limb. One patient presented with abnormal radiographs after fracture about the aneurysmal bone cyst. None of the patients had evidence of growth plate disruption. The children's ages ranged from 2 to 14 years, with a mean of 9.8 years. There were 10 boys and five girls. Lesion locations included: six in the proximal tibia, three in the distal fibula, two in the distal tibia, two in the proximal femur, one in the distal femur, and one in the distal radius. All of the lesions abutted the physeal plate and fell into one of the types in Campanacci's classification of juxtaphyseal aneurysmal bone cysts. Three lesions were classified as Type 1, eight were Type 2, and four were Type 3. This study included no cases of Type 4 or 5 lesions. Treatment of all lesions consisted of excision, curettage, and bone grafting with care taken to preserve the growth plate. Adjunctive cauterization was performed in two cases. There were no incidences of postoperative physeal plate arrest. Overgrowth of the fibula occurred in one patient. Three patients experienced recurrent lesions. One of the children underwent repeat curettage and bone grafting with no additional recurrence. In the other two children with recurrence, the lesion had grown away from the physeal plate while remaining static in size and asymptomatic. Based on this study, juxtaphyseal aneurysmal bone cysts may be treated satisfactorily with intralesional surgery and bone grafting with expectation of normal physeal growth. 相似文献
