[Bowel endometriosis. Eight cases of colorectal resection].

Colo-rectal endometriosis requiring colon resection are reported in 8 patients to illustrated the diagnostic and therapeutic problems encountered in the management of this uncommon localisation. Pericatamenial or catamenial bowel symptoms associated with pelvic genital involvement were encountered in all cases. Clinical examination, barium enema and colonoscopy are essential to guide surgical management looking for multiple localisations. However their diagnostic value is low as endometriosis rarely involves the mucosa. Endosonography appears to be very promising in evaluating the depth of infiltration of the bowel. The treatment of bowel endometriosis is controversial and varies greatly according to the patient's complaints and clinical data. The indications and limits of all treatment modalities including abstention, medical, and surgical treatment are discussed. From the cases reported we conclude that symptomatic bowel endometriosis should be fully excised whenever possible, and the surgical procedure should be adapted to the depth of infiltration. A full thickness excision or bowel resection is mandatory in patients with deep muscularis involvement. These procedures, which are often difficult due to extensive fibrosis and adhesions, may be achieved by laparoscopy in selected patients.

Laparoscopic staging of early ovarian cancer.

The relevance of staging in early ovarian carcinoma is reviewed in light of the advances in surgical laparoscopy. Data from the literature suggest that a lymphadenectomy should be performed instead of a sampling. We have realized the former through laparoscopy. In this paper we propose a detailed surgical technique, similar to the laparotomy approach, that ensures an adequate nodal evaluation. Ten patients underwent a completion of staging by laparoscopy, including peritoneal washings for cytology, peritoneal and ovarian biopsies, an infracolic omentectomy, and a lymph node dissection. The use of laparoscopy for staging of early ovarian carcinoma appears to be a valuable alternative to traditional surgical staging.

Laparoscopic radical hysterectomy for cervical cancer.

A laparoscopic approach for radical hysterectomy is described. The laparoscopic procedures are similar to those achieved previously by laparotomy, the extent of surgery being adapted to the volume of the tumour and to the associated treatments. From the results obtained in a preliminary study of 15 patients, this approach appears to be safe. This surgical treatment of cervical cancer which associates a radical procedure complying with oncological rules with a decreased morbidity seems very promising. However, laparoscopic radical hysterectomy should be considered investigational and reserved for oncology surgeons trained in extensive laparoscopic procedures. Large studies with long follow-up are necessary before this approach can be proposed as an alternative to conventional surgical approaches.

[Clinically occult invasive cancers of the breast. Apropos of 136 cases].

Between 1978 and 1991, one hundred and thirty-six surgical excision biopsies were performed in our institution for clinically occult breast cancers. A retrospective analysis of histopathologic characteristics was carried out in order to determine the prognostic factors of these cancers detected by mammography. Mammographic findings consisted of microcalcifications alone (49 cases), microcalcifications with opacity (20 cases), stellate opacity (52 cases) and well-circumscribed opacity (12 cases). Preoperative localization was achieved by mammography in 109 cases and ultrasonography in 27 cases. The size of malignant lesions ranged from 3 to 25 mm, 76 lesions were less than 10 mm in diameter. The histopathologic findings were as follows: invasive ductal cancer (IDC) 113 cases (83%), invasive lobular cancer (ILC) 11 cases (8%), ductal or lobular cancer in situ with microinvasion 12 cases (9%). Breast conserving treatment was performed in 106 cases (78%). A high proportion of well differentiated tumors was encountered-59 grade I (52%) were identified out of 113 IDC-and the incidence of axillary node metastases was less than 10%. Clinically occult breast cancers seem to exhibit favorable prognostic factors.

Cytoreductive surgery for advanced stages of ovarian cancer.

During the past two decades, maximum cytoreductive surgery (also called debulking surgery) has been the recommended surgical approach for advanced stages of ovarian carcinoma. The residual tumor volume after surgery is one of the strongest prognostic factors, and only patients who undergo complete or optimal surgery are likely to be long-term survivors (i.e., 50% after five years). A well-trained surgeon in the field of gynecologic oncology can achieve an optimal tumor reduction in up to 75% of patients with advanced stage ovarian cancer. During the procedure, bowel resection, especially rectosigmoid, must be undertaken in 30% to 40% of cases, and para-aortic and pelvic lymphadenectomy should be performed after adequate tumor reduction in the abdominal cavity. The experienced surgeon can perform these surgeries with an acceptable morbidity, allowing chemotherapy to be undertaken within the month following surgery. However, very advanced cancer with massive peritoneal carcinomatosis and/or Stage IV disease requires a very aggressive surgical procedure but yields a poor prognosis and a higher risk of unacceptable complications. For these worst cases, the concept of cytoreductive surgery is moving toward the alternative strategy of chemosurgical cytoreduction, in which interval cytoreductive surgery is undertaken after three cycles of front-line chemotherapy. The goal of this experimental strategy is to achieve a complete tumor response after front-line chemosurgical therapy, and a better quality of life.

[Prognosis and fertility after conservative treatment for ovarian tumors of limited malignity: review of 68 cases].

UNLABELLED: The aim of this retrospective study was to evaluate the rate of recurrence and the reproductive outcome after surgical conservative treatment of low malignant ovarian tumors (LMOT). MATERIAL AND METHODS: Sixty-eight patients with 50 Stage I LMOT and 18 LMOT with peritoneal implants treated conservatively at institut Gustave-Roussy, between January 1969 and December 2000. Fifty-nine patients had an unilateral adnexectomy (associated twelve times with a contralateral cystectomy), Seven had a bilateral cystectomy and two an unilateral cystectomy. Five patients received adjuvant therapy. RESULTS: With a median follow-up of 71.5 months, 16 patients recurred and one had evolutive peritoneal disease. The histologic pattern of ovarian recurrences was always of borderline type. The histologic patterns of peritoneal recurrence was similar to those initially diagnosed except in one case. Peritoneal implants, exophytic tumor and serous type tumor were significatively associated with a higher 5-year recurrence rate. Recurrence was more frequent after cystectomy than unilateral adnexectomy (p = 0.13). None of patients treated conservatively recurred under the form of ovarian carcinoma. None patient died of tumor. Nineteen patients experienced 26 pregnancies: 24 were spontaneous in a median delay of 19 months. Seven infertile patients underwent ovarian stimulation. None recurred after infertility treatments. The 2-year and 5-year cumulative pregnancy rate were respectively 41.9% and 59.8%. Four patients experienced a pregnancy after a conservative treatment of their recurrence. CONCLUSION: Despite a high recurrence rate, especially in stage II and III serous LMOT, conservative treatment of LMOT does not affect survival and should be considered in young patients. Such treatment is not advised in case of invasive peritoneal implants. Spontaneous pregnancy rate is good but the frequent infertility associated with these tumors can afterwards require ovarian stimulation. Limited number of stimulation cycles is acceptable in such patients.

Role of laparoscopy to evaluate candidates for complete cytoreduction in advanced stages of epithelial ovarian cancer.

The objective of this study was to evaluate the role of laparoscopy in selecting candidates for complete cytoreduction surgery in epithelial ovarian carcinoma. We performed an explorative laparoscopy in 15 women presenting with advanced ovarian carcinoma, and for whom the preoperative evaluation was considered unsatisfactory, to define the possibility of achieving a complete cytoreduction. We focused on three sites of carcinomatosis: bowel, liver pedicle, and right diaphragmatic dome. Laparoscopic evaluation was successful in all 15 patients. Four patients were considered to have unresectable carcinomatosis because of extensive involvement of the small bowel and therefore had no laparotomy. These women underwent neoadjuvant chemotherapy in the following 2 weeks. Eleven patients were considered to have resectable peritoneal carcinomatosis (PC). Ten women had no macroscopic residual tumor after surgery. A modified posterior exenteration was performed in five patients. The laparoscopic exploration had underestimated the liver pedicle involvement in two patients, but only one had an infracentimetric residual tumor after surgery. Laparoscopy is a reliable method of exploring PC in advanced-stage ovarian cancer. Laparoscopy may obviate the need for unnecessary laparotomy in many cases and may, therefore, contribute to a better quality of life for patients found to have unresectable disease.
