Background: Postperitoneal tumors are diseases that are difficult diagnosis, vague and unspecific clinical signs. Objective: To take out experience for clinical practice based on clinical, imaging diagnosis, pathological characteristics and management for postperitoneal tumors. Subjects and method: A retrospective study included 93 cases that diagnosed and treated for postperitoneal tumors at Cho Ray Hospital from January 2000 to November 2006. Clinical, subclinical characteristics and theirs related factors; diagnosis, operation and prognosis for postperitoneal tumors were analysed. Results: The patients\ufffd?average age was 49.98\xb116.37 years (ranged 1-85 years); the ratio of male to female was 0.86. The average time from having pain symptom to admitting hospital was 4.49\xb110.01 months (ranged from 3 days to 60 months). Clinical symptoms were fatigue (51.5%), fever (15%), jaundice (45%), anemia (23.5%), weight loss (58%), abdominal pain (75%), abdominal distention (39%), digestive disorders (31%), touching tumor (50.5%)\ufffd?The diagnosis at admitting were right (32%), wrong (60%) and unclear (8%); the preoperative diagnosis were 70%, 22% and 8%, respectively. Pathologically, 39 of 93 cases (42%) were benign tumors, and 58% were malignant tumors. 61.3% of cases removed completely tumors, 2.15% removed partially tumors. The postoperative outcomes were good (62.6%), unimproved (28.57%), and bad (3.29%). There were some complications, included perioperative bleeding (2 cases - 2.19%), postoperative complication (3 cases - 3.29%), cracked colonic junction (1 case), renal bleeding (1 case) and peritonitis (1 case). Conclusions: The surgical treatment was main method for postperitoneal tumors. The complete tumor removing based on tumor\u2019s nature, stage and related structures.

Primary mucinous cystic cystadenomas of the retroperitoneum are very rarely encountered, and there have been only about 30 cases reported in the literature. The histogenesis of primary mucinous cystadenomas is unclear. Most authors suggested that it develops through mucinous metaplasia in a pre-existing mesothelium-lined cyst. Complete surgical excision is the only treatment and it is required for the final diagnosis and cure. We present here a case report of a 38-year-old Korean woman with primary retroperitoneal cystadenoma. It was a thin-walled, multilocular cyst with a dominant loculus that measured 10.0 X 7.5 X 5.5 cm3 in size, and to the best of our knowledge, this is the first such case to be reported in in Korea.

Primary retroperitoneal mucinous cystadenocarcinoma is a rare tumor. Only about 30 such cases have been reported in the worldwide literature, and a few Korean cases have been reported. The pathogenesis is not clear, and coelomic metaplasia of the retroperitoneal mesothelium has gained wide support. There is no consensus on the appropriate treatment, but surgical exploration is needed for the diagnosis and treatment, and adjuvant chemotherapy may be recommended following complete surgical excision. The long-term prognosis has not been established. We report here on a 32-year-old woman who was diagnosed as having a retroperitoneal mucinous cystadenocarcinoma with mural nodules of sarcomatoid change. Tumor excision and adjuvant chemotherapy were done and the patient is doing well without any evidence of recurrence at 42 months postoperatively.

OBJECTIVETo search the etiologic factor, clinical diagnosis points and treatment of postoperative intussusception (PI).

METHODSTo retrospectively review the clinical materials of 14 cases with PI including the cause of disease and treatment.

RESULTSPI occurred within 10 days (average 4 days) after the primary operation. Bowel obstructive symptoms gradually emerged. One case was diagnosed with intussusception by sonography and received enema reduction of intussusception by hydrostatic pressure. Thirteen cases were performed secondary operation. Small intestine was main site of intussusception. Manual reduction of the lesion was performed in 12 cases and bowel resection and anastomosis was done in 1 case with bowel necrosis.

CONCLUSIONPI should be suspected if child presents with the symptoms of ileus in early postoperative period. Abdominal sonography may have some value on diagnosis of PI. Operation is the first choice for the treatment of PI.

OBJECTIVETo compare the safety, feasibility and efficacy of transperitoneal and retroperitoneal laparoscopic partial nephrectomy (LPN) in the treatment of renal tumors with R. E. N. A. L score more than 7.

METHODSThe clinical data were collected from 62 patients undergoing transperitoneal LPN (32 cases) and retroperitoneal LPN (30 cases) for a complex renal mass (R.E.N.A.L. score≥7) between January 2012 and March 2014. The surgical and early postoperative outcomes and complications were analyzed to evaluate the efficacy of the treatments. The mean operative time, estimated blood loss, warm ischemia time, surgical complications, blood transfusion rate, tolerating regular diet time, postoperative hospital stay and surgical margin were compared between the two groups.

RESULTSThe operations were completed successfully in all cases except for 1 case in transperitoneal group and 3 in retroperitoneal group that required conversion to open surgery. No significant differences were found in age, body mass index, ASA score, Charlson comorbidity index, tumor size or R.E.N.A.L. nephrometry score (P>0.05), nor in estimated blood loss, warm ischemia time, intraoperative complication, blood transfusion rate or surgical margin between the two groups (P>0.05, respectively). The transperitoneal LPN group had a shorter mean operative time than retroperitoneal LPN group (210.4∓59.2 vs 252∓58.3 min, P<0.05) but showed longer tolerating regular diet time (47∓10 h vs 23∓6 h, P<0.05) and postoperative hospital stay time (8.4∓1.9 days vs 6.5∓1.6 days, P<0.05).

CONCLUSIONBoth transperitoneal LPN and retroperitoneal LPN are safe, feasible and effective for surgical management of complex localized tumors, but the transperitoneal procedure offers larger operative space with better exposure; the retroperitoneal procedure better promotes postoperative recovery of the patients.

Schwannoma is a benign neoplasm of the Schwann cells of the neural sheath. Most schwannomas occur in the head and neck, and extremities and rarely in the retroperitoneal space. The differentiation of a schwannoma from other malignant tumor or benign tumor is very difficult on a preoperative examination with ultrasonography, computed tomography or magnetic resonance imaging. Furthermore, the lesion with increased fluorodeoxyglucose uptake in PET-CT cannot exclude malignant tumor. Therefore, this lesion needs surgical excision and a histological examination with immunohistochemical staining. We report a case of schwannoma occuring in the retroperitoneal space that incidentally discovered by PET-CT for health-check up. Pathologic confirmation by laparoscopic excision was done.

Retroperitoneal cystic lymphangioma is a rare congenital malformation. The majority of lymphangiomas are present at birth and nearly all present before the age of two years. We report a case of giant cystic retroperitoneal lymphangioma in a patient who first presented with symptoms at the age of 7, underwent surgery, and who then suffered a recurrent mass 11 years later.

Haemangioma of the retroperitoneal space is a rare benign capillary malformation, which can grow significantly in pregnancy due to the multiple associated cardiovascular changes. We herein describe the case of a pregnant woman with an extensive right retroperitoneal haemangioma extending from the level of the renal hilum, across the lateral anterior abdominal wall and into the thigh. We also highlight the challenges faced in the management of the patient's delivery process. To the best of our knowledge, this is the first case of such nature and severity described in the English literature.
