Locally advanced tumor with involvement of surrounding tissues and organs is a common situation in pelvic malignancies. Up to 10% of newly diagnosed rectal cancer cases infiltrate to adjacent tissues and organs. Satisfactory resection margins obtained by pelvic exenteration can achieve a 5-year survival rate similar to cases that without adjacent tissue invasion. The 5-year survival rate of patients with locally recurrent pelvic malignancies is almost zero if they are treated only with radiotherapy and chemotherapy. To obtain negative margins through pelvic exenteration is the only chance for a long-term survival of these patients. However, pelvic exenteration is a complicated procedure with higher morbidity and mortality. The development of fascia anatomy enables surgeons to have a deeper understanding and comprehensive application of pelvic fasciae. Meanwhile, the improvement of laparoscopic technology provides a clearer view for surgeons and enables the application of minimally invasive techniques in complex pelvic exenteration. The fascial space priority approach is based on the fascia anatomy of pelvis and giving priority to the separation of the pelvic avascular fascial spaces, which provides a reproducible surgical approach for complex pelvic exenteration.

OBJECTIVESTo review the patients with malignant pelvic tumors involving sacrum treated surgically and to discuss the methods of resection of tumors and reconstruction of defects.

METHODSNineteen patients with malignant pelvic tumors involving the sacrum were treated surgically in People's Hospital between July 1999 and July 2007. The series comprised 12 males and 7 females. Five patients were diagnosed with chondrosarcoma, 4 with Ewing sarcoma, 4 with osteosarcoma, 1 with malignant fibrohistiocytoma (MFH), 1 with giant cell tumor (GCT), and 4 with metastatic bone tumors. Acetabulum was preserved after resection of the iliac and sacral tumor and reconstructed with screw and rod system in 10 patients. Among this 10 patients, 5 of them were also done bone graft. Acetabulum was not preserved after resection of the iliac and sacral tumor and the defect was reconstructed with modular hemipelvic prosthesis in 9 patients.

RESULTSOncology result: 7 patients (7/19, 36.9%) had local relapse, including of 2 osteosarcoma, 2 chondrosarcoma, 2 Ewing sarcoma and 1 metastatic tumor. Two of 4 osteosarcoma, 2 of 4 Ewing sarcoma, 1 of 5 chondrosarcoma and 1 MFH patients died of lung metastasis. Two patients with metastatic lung cancer died of the disease 1 year after surgery. One patient with kidney carcinoma and 1 with thyroid carcinoma alive without of disease. Functional result: 8 patients with acetabular reconstruction after resection of pelvic and sacral tumors could walk with a cane 2 months after surgery. Average ISOLS function score was 20, including good in 3, fair in 5 and poor in 1 patient. One of the patient with modular hemipelvic prosthetic reconstruction occurred dislocation treated with 1 month after surgery and experienced open reduction. Hemipelvic prosthesis was took out in 1 patient because of the deep infection.

CONCLUSIONSFor patients with acetabulum preserved after resection of the iliac and sacral tumor, reconstructed with screw and rod system combining with bone graft is an ideal method for restoration. Bone graft with resected femoral head and neck on residual sacrum and modular hemipelvic prosthetic reconstruction after resection of the pelvic tumor involving of the secrum is a good choose.

OBJECTIVE: The aim of this paper was to describe the operative details for en bloc removal of the adnexal tumor, uterus, pelvic peritoneum, and rectosigmoid colon with colorectal anastomosis in advanced epithelial ovarian cancer patients with widespread pelvic involvement. METHODS: The patient presented with good performance status and huge pelvic tumor extensively infiltrating into adjacent pelvic organs and obliterating the cul-de-sac. The patient underwent en bloc pelvic resection as primary cytoreductive surgery. En bloc pelvic resection procedure is initiated by carrying a circumscribing peritoneal incision to include all pan-pelvic disease within this incision. After retroperitoneal pelvic dissection, the round ligaments and infundibulopelvic ligaments are divided. The ureters are dissected and mobilized from the peritoneum. After dissecting off the anterior pelvic peritoneum overlying the bladder with its tumor nodules, the bladder is mobilized caudally and the vesicovaginal space is developed. The uterine vessels are divided at the level of the ureters, and the paracervical tissues (or parametria) are divided. The proximal sigmoid colon is divided above the most proximal extent of gross tumor using a ligating and dividing stapling device. The sigmoid mesentery is ligated and divided including the superior rectal vessels. The pararectal and retrorectal spaces are further developed and dissected down to the level of the pelvic floor. The posterior dissection is progressed and moves to the right and then to the left of the rectum. The rectal pillars including the middle rectal vessels are ligated and divided. Hysterectomy is completed in a retrograde fashion. The distal rectum is divided using a linear stapler. The specimen is removed en bloc with the uterus, adnexa, pelvic peritoneum, rectosigmoid colon, and tumor masses leaving a macroscopically tumor-free pelvis. Colorectal anastomosis was completed using stapling device. RESULTS: En bloc pelvic resection was performed by total abdominal hysterectomy, bilateral salpingo-oophorectomy, pelvic peritonectomy, and rectosigmoid colectomy with colorectal anastomosis using a stapling device. Complete clearance of pelvic disease leaving no gross residual disease was possible using en bloc pelvic resection. CONCLUSION: En bloc pelvic resection is effective for achieving maximal cytoreduction with the elimination of the pelvic disease in advanced primary ovarian cancer patients with extensive pelvic organ involvement.

OBJECTIVETo explore a better operative approach to resect complicated pelvic retroperitoneal tumors.

METHODSA total of 28 patients with complicated pelvic retroperitoneal tumors who received surgical resection in our hospital from 2006 to 2010 were included in this study. The surgical operation was assisted with an arc-shaped transperineal incision in front of the apex of coccyx. The operation time, intraoperative blood loss, death toll and length of hospital stay of the patients were retrospectively analyzed.

RESULTSThe median operation time was 122.5 minutes. The median blood loss was 420 ml, and the median length of hospital stay of the patients was 17.5 days. There was no postoperative death in this group of patients.

CONCLUSIONWith the assistance of this arc-shaped transperineal incision in front of the apex of coccyx, the resection of pelvic retroperitoneal tumors can be effectively improved and the surgery risk is reduced.

OBJECTIVETo evaluate the methods of surgery for extraperitoneal pelvic neoplasms.

METHODSClinical data related to surgery of 84 cases of extraperitoneal pelvic neoplasms were extracted and retrospectively analyzed.

RESULTSAll 84 patients underwent operations, including one of them who received 4 operations within 6 months for resection of a single tumor. 58 abdominal, 16 buttock and 10 combined incisions were made in the series. Pelvic organs and structures were co-resected in 35 cases, including total pelvic exenteration in 2 cases and anterior pelvic exenteration in 2 cases. Common and/or external iliac vessels were resected and transplantations of artificial vessel were carried in 5 cases. Internal iliac arteries were ligated in 10 cases. The mean blood lose was 2 385 ml in our series and the largest was 15 000 ml. The complete resection rate of tumor was 81% for 84 operations and the largest resected tumor was 30 cm x 30 cm x 25 cm. There was no hospitalized death, and postoperative complication rate was 7% (6/84) in our series. Only 1 death were seen during the mean period of postoperative follow-up of 54 months, 22 operations were carried for 21 cases of recurrence, including 7 operations for 7 recurrences in a case within 12 years.

CONCLUSIONSMaking adequate abdominal or/and buttock incisions, exenterations of involved pelvic organs and structures, total pelvic exenteration if necessary, appropriate management of iliac vessels, planned re-operation for one tumor, and re-operation for recurrences are important methods for the treatment of extraperitoneal pelvic neoplasms.

OBJECTIVETo compare the clinicopathological characters and operative prognosis of gastric cancer complicated with Krukenberg tumor and with pelvic peritoneal dissemination.

METHODSThirty-nine female cases of gastric carcinoma with pelvic metastasis were treated operated on between August 1994 and March 2006. Among them, 18 cases were complicated with Krukenberg tumor and 21 cases with pelvic peritoneal dissemination. The clinicopathological characters in the two groups were recorded and compared and the operative prognosis were analyzed.

RESULTSThere was no significant difference in age, tumor location and size, hepatic metastasis, organic encroachment, infiltration degree, positive lymph nodes, differentiated degree, tissue typing, Borrmann typing, value of carcinoembryonic antigen between the two groups (P > 0.05). The rate of P3 (peritoneal dissemination) in the cases of Krukenberg tumor (44.4%) was significantly lower than that in pelvic peritoneal dissemination group (85.7%) (P < 0.01), whereas the focal resection rate (77.8%) and multi-organ dissection rate (55.6%) were significantly higher than in pelvic peritoneal dissemination (38.0%, 23.8%) (P < 0.05). The mean survival of all cases was 12.6 months. The mean survival in the patients with Krukenberg tumor and pelvic peritoneal dissemination was 20.5, 15.0 months, respectively (P < 0.05). The mean survival of total focal resection, palliative focal resection, non-focal resection was 19.9, 12.5 and 5.7 months, respectively (P < 0.01). Non-focal resection, pelvic peritoneal dissemination, P3 of peritoneal implantation, hepatic metastasis, organic encroachment, total gastric cancer were unfavorable prognosis factors for all cases.

CONCLUSIONSCompared with pelvic peritoneal dissemination, the gastric cancer with Krukenberg tumor is associated with more limited peritoneal dissemination, higher resection rate and better prognosis. Focal resection can improve the prognosis.
