Long-term outcome of consecutive case series of congenital isolated agenesis of corpus callosum.

OBJECTIVE: To describe the long-term outcome of children with prenatally diagnosed isolated complete agenesis of the corpus callosum (cACC). METHODS: In this single-center case series, we reviewed retrospectively the charts of fetuses referred to our fetal therapy unit from January 2004 to July 2020 for a suspected anomaly of the corpus callosum (CC). Cases with prenatally diagnosed isolated cACC were included. Fetal karyotype and comparative genomic hybridization microarray of amniotic fluid, in addition to fetal magnetic resonance imaging, were offered to all pregnant women with a diagnosis of fetal CC malformation. The surviving children were enrolled in the neurodevelopmental follow-up program at our institution, which included postnatal magnetic resonance imaging, serial neurological examinations and neurodevelopmental evaluations with standardized tests according to age. Families living in remote areas or far from our institution were offered a structured ad-hoc phone interview. RESULTS: A total of 128 pregnancies with fetal CC malformation were identified (mean gestational age at diagnosis, 24.5 (range, 21-34) weeks), of which 53 cases were diagnosed prenatally with apparently isolated cACC. Of these, 12 cases underwent termination of pregnancy, one resulted in intrauterine demise at 24 weeks of gestation and 13 cases were lost to follow-up. Of the remaining 27 children, one was excluded due to an associated chromosomal anomaly (8p21.3q11.21 mosaic duplication) diagnosed after birth, which could have been detected prenatally if the parents had consented to amniocentesis. In the 26 children included in the analysis, neurodevelopmental follow-up was available for a median of 3 (range, 1-16) years. Three (11.5%) infants had severe neurodevelopmental impairment, two of which were diagnosed postnatally with a genetic syndrome (Mowat-Wilson syndrome and Vici syndrome) that would not have been diagnosed prenatally. Seven (26.9%) children had mild neurodevelopmental impairment and 16 (61.5%) had normal neurodevelopmental outcome. The Full-Scale Intelligence Quotients of the three children with severe neurodevelopmental impairment were 50, 64 and 63, respectively, while that of the remaining children was in the normal range (median, 101; range, 89-119). CONCLUSIONS: In 88% of the children with cACC included in this study, neurodevelopment was not severely impaired. However, long-term follow-up is recommended in all cases of congenital isolated cACC to recognize subtle neurodevelopmental disorders as early as possible. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

Pattern of recurrence in patients with endometrial cancer: A retrospective study.

INTRODUCTION: Endometrial cancer (EC) known prognostic factors are not sufficient to predict either outcome or recurrence rate/site: to investigate EC recurrence patterns according to ESMO-ESGO-ESTRO risk classes, could be beneficial for a more tailored adjuvant treatment and follow-up schedule. METHODS: 758 women diagnosed with EC, and a 5-years follow-up, were enrolled: they were divided into the ESMO-ESGO-ESTRO risk classes (low LR, intermediate IR, intermediate-high I-HR, and highrisk HR) and surgically treated as recommended, followed by adjuvants therapies when appropriate. RESULTS: Higher recurrence rate (RR) was significantly detected (p < 0,001) in the HR group (40,3%) compared to LR (9,6%), IR (16,7%) and I-HR (17,1%). Recurrences were detected more frequently at distant sites (64%) compared to pelvic (25,3%) and lymph nodes (10,7%) recurrences (p < 0,0001): only in LR group, no differences were detected between local and distant recurrences. 5-Year distant-free (LR 99%, IR 94%,I-HR 86%, HR 88%) and local-free survivals (LR 99%, IR 100%,I-HR 98%, HR 95%) significantly differ between groups (p < 0,0001 and p = 0,003, respectively). Adjuvant therapy modifies RRs only in LR group (p = 0,01). CONCLUSION: To identify biological factors to stratify patients at higher risk of relapse is needed. Distant site relapse could be the main reason of endometrial cancer failure follow-up, independently or in addition to their risk class prognosis.

Surgical and oncological outcome of robotic surgery compared to laparoscopic and abdominal surgery in the management of endometrial cancer.

OBJECTIVE: To compare different techniques of minimally invasive surgery (laparoscopy and robotics) to abdominal surgery in order to identify the optimal surgical technique in the treatment of endometrial cancer. METHODS AND MATERIALS: A single-institutional, matched, retrospective, cohort study was performed. All patients with clinical stage I or occult stage II endometrial cancer who underwent robotic hysterectomy, bilateral salpingo-oophorectomy ± lymphadenectomy from August 2010 and December 2013 were identified. Surgical and oncological outcomes were compared with patients matched by age, body mass index, tumor histology, and grade, who underwent abdominal or laparoscopic surgery between January 2001 and December 2013. RESULTS: Three groups were identified: 177 laparotomies (group A), 277 laparoscopies (group B) and 72 robotics (group C). There were no statistically significant differences between the three groups in terms of age, BMI and FIGO stage. The operative time was shortest in group B (p = 0.0001). Blood loss and transfusions were equivalent in group B and C, while they were greater in group A (p = 0.0001). The intra-operative, early and late postoperative complications, rate of conversion, the re-intervention and median hospital stay were lower in group C. The rate of recurrence and death from disease was similar in all three groups. CONCLUSIONS: Minimally invasive surgery was superior to abdominal surgery in terms of surgical outcomes. Robotic surgery was superior to laparoscopy in terms of intra- and post-operative complications, conversion rates, length of hospital stay and re-interventions. In terms of oncological outcomes the three groups were equivalent.

Laparoscopic versus robotic radical hysterectomy after neoadjuvant chemotherapy in locally advanced cervical cancer: a case control study.

OBJECTIVE: To compare the surgical outcome of robotic radical hysterectomy (RRH) versus laparoscopic radical hysterectomy (LRH) for the treatment of locally advanced cervical cancer (LACC) after neoadjuvant chemotherapy (NACT). MATERIALS AND METHODS: From August 1st 2010 to July 1st 2012 a prospective data collection of women undergoing RRH for cervical cancer stage FIGO IB2 to IIB, after neoadjuvant chemotherapy, was conducted at National Cancer Institute "Regina Elena" of Rome. All patients deemed operable underwent class C1 RRH with pelvic lymphadenectomy within 4 weeks from the last chemotherapy cycle. RESULTS: A total of 25 RRH were analyzed, and compared with 25 historic LRH cases. The groups did not differ significantly in body mass index, stage, histology, number of pelvic lymph nodes removed. The median operative time was the same in the two groups with 190 min respectively. The median estimated blood loss (EBL) was statistically significant in favor of RRH group. Median length of stay was shorter, for the RRH group (4 versus 6 days, P = 0.28). There was no significant difference in terms of intraoperative and postoperative complications between groups but in the RRH group we observed a greater number of total complications compared to the control group. CONCLUSION: This study shows that RRH is safe and feasible in LACC after NACT compare to LRH. However, a comparison of oncologic outcomes and cost-benefit analysis is still needed and it has to be carefully evaluated in the future.

Endometrial biopsy by means of the hysteroscopic resectoscope for the evaluation of tumor differentiation in endometrial cancer: a pilot study.

AIMS: To assess the diagnostic accuracy of endometrial biopsy by means of the hysteroscopic resectoscope (EBHR) in evaluating tumor differentiation in patients with endometrial cancer. METHODS: Between January and December 2005, all the women with a diagnosis of endometrioid adenocarcinoma of the uterus, when admitted to hospital, were enrolled for this study. Patients eligible for surgical treatment underwent a preoperative work-up consisting in pelvic magnetic resonance imaging (MRI) and EBHR. In all patients submitted to a hysterectomy, a comparison between pre- and postoperative tumor grade was carried out. RESULTS: 42 women were enrolled in the study. Hysteroscopic biopsy was carried out in 39 patients (mean age 62.5 years, range 33-79; FIGO stage I: 34, stage II-IV: 5). No complication related to hysteroscopy was observed. The preoperative tumor grade by hysteroscopy correlated with the final grade in 97.1% of cases. No patient had positive peritoneal washing and after a median follow-up of ten months no intraperitoneal tumor relapse was observed. CONCLUSION: EBHR is a very accurate diagnostic procedure for assessing the preoperative tumor grade in patients with endometrial cancer.

Pelvic and aortic lymphadenectomy.

Pelvic and aortic lymphadenectomy for gynecologic malignancies has changed from a random "picking" of some pelvic and aortic lymph nodes to a well-established technique based on adequate knowledge of the patterns of spread of the primary tumor. The identification of the node groups to remove, the number of nodes to count, and the border of dissection in the different clinical situations make pelvic and aortic lymphadenectomy a reproducible surgical intervention. The large experience accumulated over the years has greatly improved the technique and perioperative and complication management. The improved knowledge of the natural history of gynecologic tumors has refined the indications for lymph node dissection. Today, pelvic and aortic lymphadenectomy is primarily a staging procedure. The therapeutic value of lymphadenectomy is recognized in the surgical treatment of cervical cancer, but it is still under evaluation in ovarian and endometrial tumors.

Early cervical carcinoma: the natural history of lymph node involvement redefined on the basis of thorough parametrectomy and giant section study.

BACKGROUND: Although parametrectomy is the most difficult step in the surgical treatment of cervical carcinoma and is the main cause of postoperative complications, little attention has been given to the patterns of parametrial spread. METHODS: Sixty-nine patients with previously untreated cervical carcinoma (Fédération Internationale de Gynécologie et d'Obstétrique [FIGO] Stage IB1, 49 patients [71%]; Stage IB2, 8 patients [12%]; and Stage IIA, 12 patients [17%]; squamous, 59 patients [86%]; and adenocarcinoma, 10 patients [14%]) underwent radical hysterectomy and pelvic +/- aortic lymphadenectomy. Hysterectomy specimens were processed with the giant section technique. To obtain a thorough three-dimensional assessment of the paracervical tissue, both the superficial and deep layers of the cervicovesical ligament (anterior parametrium) and the uterosacral ligament (posterior parametrium) were separated from the uterus and submitted for pathologic evaluation. After resection of the lateral parametrium with hemoclips, the lympho-fatty tissue remaining around the pudendal vessels was removed carefully and referred to as "the distal part of the lateral parametrium." RESULTS: When analyzing all the parametria, lymph nodes were present in 64 patients (93%). Clinically undetected parametrial involvement was found by pathologic examination in 15 Stage IB1 patients (31%), 5 Stage IB2 patients (63%), and 7 Stage IIA patients (58%). Metastases were found in the cardinal, cervicovesical, and sacrouterine ligaments and principally were comprised of lymph node and vascular space invasion. Twenty-five patients (36%) had pelvic lymph node metastases whereas concomitant parametrial involvement was observed in all patients. The overall 5-year survival was 91%, being higher for parametria and lymph node negative patients (100%) than for those with lymph node and/or parametrial metastases (78%). CONCLUSIONS: A three-dimensional pathologic assessment showed that subclinical parametrial spreading of the so-called "early" tumors (Stage IB-IIA) occurred in approximately 30-60% of these patients, and metastasis to the pelvic lymph nodes always was associated with parametrial disease. A better understanding of the patterns of parametrial diffusion will improve knowledge of the natural history of cervical carcinoma and in the future may influence the treatment of these patients. Furthermore, pathologic assessment of cervical carcinoma should be modified to evaluate correctly the parametrial status of each patient. The current routine pathologic evaluation of the parametria makes it very difficult to detect lymph node metastases and tumor emboli.

Early feeding compared with nasogastric decompression after major oncologic gynecologic surgery: a randomized study.

OBJECTIVE: To evaluate the feasibility, safety, and tolerance of early feeding in patients undergoing surgery for gynecologic malignancies. METHODS: Patients were stratified according to operative time and type of tumor and were randomized into two arms: A) early oral feeding and B) nasogastric decompression followed by feeding at the first passage of flatus. Variables assessed included nausea, vomiting, time to first passage of flatus and stool, time elapsed before adequate tolerance of a regular diet, postoperative stay, and complications. RESULTS: Sixty-one patients were randomized into each arm. The types of tumor, the surgical procedures performed, and the operative times were similar in both groups. Early oral feeding in patients in arm A was associated with a significantly faster resolution of postoperative ileus (P < .01), with a more rapid return to a regular diet (P < .01), with an earlier first passage of stool (P < .01), and with a shorter postoperative stay (P < .05) than patients in arm B. Rates of nausea and vomiting were similar in both arms. Hindered deglutition and nasal soreness caused by the nasogastric tube were observed in 88% of patients in arm B. Insertion of a nasogastric tube was necessary in six patients in arm A (10%), and three of these had postoperative complications. Thus, early feeding was feasible in 95% of patients and did not seem to be related to preoperative chemotherapy, tumor type, or lymphadenectomy. CONCLUSION: Early feeding is feasible and well tolerated and is associated with reduced postoperative discomfort and a more rapid recovery in patients undergoing major surgery for gynecologic malignancies.

Laparoscopic abdominal staging in locally advanced cervical cancer.

In order to determine patterns of peritoneal spread in locally advanced cervical cancer, 59 patients with previously untreated stages IB and IIA tumor size > 4 cm, IIB, III and IVA cervical cancer were considered for laparoscopic abdominal staging. Fifty-six patients (95%) were considered suitable and underwent laparoscopy. Peritoneal spread was found in 15 (27%) patients. The location was pelvic in nine (17%), extra-pelvic in one (2%), both pelvic and extra-pelvic in four (8%). Peritoneal washing was positive in five (9%) patients, being the unique site of peritoneal spread in one. Overall, 16 (29%) patients had evidence of abdominal disease. The median number of positive sites was one (range 1-4); uterine serosa was positive in nine (17%) patients, pre-vesical peritoneum in seven (13%), Douglas peritoneum in five (10%), paracolic gutter in three (6%), adnexa and omentum in two (4%), and sigmoid serosa in one (2%) patient. One operative complication occurred and all patients were discharged the day after the procedure. To date, with a median follow-up of 27 months (range 7-38), no metastasis has been detected at the trocar insertion sites. To summarize, laparoscopic staging in locally advanced cervical cancer is a safe, feasible and simple technique which is able to accurately detect abdominal disease.

Long-term survival following neoadjuvant chemotherapy and radical surgery in locally advanced cervical cancer.

The aim of this study was to analyse the long-term survival and the relationships between prognostic factors at presentation, chemoresponsiveness and disease outcome in patients with locally advanced cervical cancer treated by neoadjuvant chemotherapy and radical surgery (RS). Two consecutive studies of neoadjuvant chemotherapy containing cisplatin, bleomycin plus/minus methotrexate followed by radical hysterectomy and systematic aortic and pelvic lymphadenectomy were carried out between January 1986 and September 1990 on 130 patients with > or = 4 cm stage IB2-III cervical cancer. Survival analysis was performed using the Kaplan and Meier test and Cox's multivariate regression analysis. 128 (98%) of the patients enrolled were evaluable for clinical response and survival, 83% (106) of the patients responded to chemotherapy, with a 15% complete response rate. Logistic regression analysis demonstrated that International Federation of Gynecology and Obstetrics (FIGO) stage, cervical tumour size, parametrial involvement and histotype are highly predictive of response. Responding patients underwent laparotomy, but 8% were not amenable for radical surgery. The 10-year survival estimates were 91%, 80% and 34.5% for stage IB2-IIA bulky, IIB and III, respectively (P < 0.001). After Cox's regression analysis, the parameters significantly associated with survival were the same factors predicting response to neoadjuvant chemotherapy. No stage IB2-IIA bulky patient has so far relapsed, while 12% stage IIB and 56% stage III patients recurred. The 10-year disease-free survival estimates are 91% and 44% for stage IB2-IIB and III, respectively (P < 0.001). Metastatic nodes and persistent tumour in the parametria were the only two independent factors for disease-free survival after multiple regression analysis. After a long-term follow-up (median follow-up 98 months (20-129+)), our results give new evidence of the prognostic value of response to neoadjuvant chemotherapy and of a possible therapeutic benefit of the sequential treatment adopted which, however, must be verified in a randomised setting.

A randomized study comparing retroperitoneal drainage with no drainage after lymphadenectomy in gynecologic malignancies.

OBJECTIVE: To evaluate the clinical effectiveness of retroperitoneal drainage following lymphadenectomy in gynecologic surgery. METHODS: One hundred thirty-seven consecutive patients undergoing systematic lymphadenectomy for gynecologic malignancies were randomized to receive (Group A, 68) or not (Group B, 69) retroperitoneal drainage. The pelvic peritoneum and the paracolic gutters were not sutured after node dissection. Perioperative data and complications were recorded. RESULTS: Clinical and surgical parameters were comparable in the two groups. Postoperative hospital stay was significantly shorter in Group B (P < 0.001), whereas the complication rate was significantly higher in Group A (P = 0.01). This was mainly due to a significant increase in lymphocyst and lymphocyst-related morbidity. Sonographic monitoring for lymphocyst showed free abdominal fluid in 18% of drained and 36% of not-drained patients (P = 0.03). Symptomatic ascites developed in 2 drained (3%) and 3 not-drained (4%) patients (NS), respectively. CONCLUSIONS: Prophylactic drainage of the retroperitoneum seems to increase lymphadenectomy-related morbidity and postoperative stay. Therefore, routine drainage following lymphadenectomy seems to be no longer indicated when the retroperitoneum is left open.

Modified type IV-V radical hysterectomy with systematic pelvic and aortic lymphadenectomy in the treatment of patients with stage III cervical carcinoma. Feasibility, technique, and clinical results.

BACKGROUND: Due to the high prevalence of perioperative major morbidity and the difficulties in achieving surgical disease free margins, surgery has had no role in the treatment of patients with Stage III cervical carcinoma. METHODS: Forty-two women with International Federation of Gynecology and Obstetrics (FIGO) Stage III cervical carcinoma responding to platinum-based neoadjuvant chemotherapy underwent the maximum surgical effort, comprised of a modified type IV-V radical hysterectomy (37 patients) or anterior pelvectomy (5 patients) with systematic pelvic and aortic lymphadenectomy. Feasibility, modifications of surgical technique, and pathologic and clinical data were analyzed. RESULTS: Surgery was feasible in all 42 patients intraoperatively selected. Disease free margins were achieved in all but one patient. The median operating time was 390 minutes, and the median estimated blood loss was 800 mL. In the last series of patients, these figures declined to 320 minutes and 600 mL, respectively. Major morbidity consisted of severe intraoperative hemorrhage in two patients, pulmonary embolism in four, ureteral fistula in three, and laparocele in three. The number of lymph nodes removed ranged from 30 to 117 with a median of 56. The mean lengths of vagina and lateral parametrium resected were 55 and 48 mm, respectively. Despite perioperative chemotherapy, lymph node metastasis was present in 36% of patients, parametrial disease in 38%, and vaginal disease in 45%. After a median follow-up of 53 months, the 5-year overall and disease-free survival rates of radically operated patients were 70% and 58%, respectively. CONCLUSIONS: Thanks to improved surgical technique and perioperative care, extended radical surgery appears to be feasible with acceptable morbidity in chemosensitive women with Stage III cervical carcinoma and may constitute a valid alternative to radiotherapy in these patients.

Lymphatic spread of cervical cancer: an anatomical and pathological study based on 225 radical hysterectomies with systematic pelvic and aortic lymphadenectomy.

To assess the patterns of lymphatic spread in cervical carcinoma, radical hysterectomy with systematic lymphadenectomy was performed in 66 patients FIGO stage IB-IIA <4 cm, and 159 patients stage IB-IIA >4 cm to stage IV. The latter patients were treated with neoadjuvant chemotherapy (NACT). Parametria were evaluated by the giant section technique in 109 patients. In 40 of these, the superficial and deep layers of the vesicouterine ligament, the sacrouterine ligament, and the distal part of the cardinal ligament were separately evaluated. The median number of nodes removed was 48 pelvic (range 20-107) and 22 aortic (range 7-64). Positive nodes were found in 14 (21%) stage IB-IIA <4 cm and in 38 (23%) NACT-treated patients, all having pelvic node metastasis. Aortic nodes were involved in 2 (3%) and 5 (3%) patients, respectively. Solitary metastases were found in the superficial obturator (21% of stage IB-IIA <4 cm and 31% of NACT-treated positive node patients, respectively), external iliac (7 and 3%, respectively), and common iliac nodes (7 and 3%, respectively). Parametrial nodes were found in 59% of giant sections (8% metastatic). The superficial and deep layers of the vesicouterine ligament, the uterosacral ligament, and the distal part of the lateral parametrium revealed the presence of nodes in 33% (no metastatic nodes), 26% (3% metastatic), 5% (no metastatic nodes), and 70% (5% metastatic) of patients, respectively. Overall, parametrial nodes were positive in 12% of stage IB-IIA <4 cm and 7% of NACT-treated patients. The diameter of node metastasis was <10 mm in more than 80% of positive nodes. In conclusion, parametrial nodes were mainly located in the cardinal and vesicouterine ligaments, both being a potential site of metastasis. The superficial obturator, external iliac, common iliac, paracaval, intercavoaortic, and paraaortic nodes were the groups more frequently involved. These data may be useful for tailoring radical hysterectomy and lymphadenectomy according to the primary tumor and the surgeon's intent.

Locally advanced cervical adenocarcinoma: is there a place for chemo-surgical treatment?

The increased frequency and poor prognosis of cervical adenocarcinoma call for new therapeutic strategies, especially in locally advanced disease. Combined neoadjuvant chemotherapy (NACT)-radical surgery (RS) has been investigated to assess its feasibility and the possible impact on disease outcome. Data were pooled from three consecutive trials on a total of 42 patients with FIGO Stage IB-IIA >4 cm (9), IIB (19), and IIIB (14) cervical adenocarcinomas. NACT regimens consisted of cisplatin (P), bleomycin (B) and methotrexate, high-dose PB, and P and doxorubicin combinations for one to three cycles. Responding patients underwent RS while those still ineligible for RS underwent radiotherapy. Fisher and chi squared tests were used to detect significant factors affecting response to NACT. Cox multivariate regression analysis was used to evaluate parameters affecting response and survival. Medians and life tables were computed by the method of Kaplan and Meier. Median follow-up times were 56 (17-95) and 54 months (15-92) from enrollment and RS, respectively. NACT-induced toxicity was generally mild and did not compromise RS when indicated. The 33 (79%) responders underwent laparotomy, while the 9 nonresponders received radiotherapy. RS was feasible in 29 (69%) patients. Macroscopic intraperitoneal tumor (IPT) excluded abandoning RS in 4 cases. Mild to moderate RS-related complications were seen in 41% of cases with the same pattern as in the absence of any prior treatment. In patients undergoing RS, node metastasis and microscopic IPT were detected in 2 (7%) and 3 (10%) patients, respectively. The 5-year overall and disease-free survivals were 71% (100% IB-IIA and 84% IIB vs 36% IIIB; P = 0.001) and 88%, respectively. None of the nonresponders survived (median 10 months, 6-25), compared with an 84% 5-year survival of responders (P < 0.001). FIGO stage and parametrial involvement significantly predicted response to NACT which was the only independent variable affecting survival (P = 0.006). This retrospective study provided evidence of the chemosensitivity of locally advanced cervical adenocarcinoma and that chemoresponsiveness is the most potent predictor of cure, as demonstrated in squamous cell cervical cancer. Combined NACT and RS is a feasible treatment which seems to be able to improve the outcome of Stage IB-IIB cervical adenocarcinoma. Randomized trials comparing this new strategy with conventional treatments seem to be warranted.

The pelvic retroperitoneal approach in the treatment of advanced ovarian carcinoma.

OBJECTIVE: To evaluate the feasibility, complications, and clinical role of pelvic cytoreduction using the retroperitoneal approach in the treatment of advanced ovarian cancer. METHODS: We studied 66 women with previously untreated advanced ovarian cancer who underwent pelvic retroperitoneal surgery. The possibility of achieving extrapelvic cytoreduction (residual disease less than 2 cm), involvement of the Douglas cul-de-sac or vesicouterine fold, or the presence of a frozen pelvis were indications for the retroperitoneal approach. Operative time, blood loss and transfusions, perioperative complications, and postoperative stay were analyzed prospectively. The performance status of each patient was assessed preoperatively and postoperatively. RESULTS: The pelvic retroperitoneal approach was used in 66 of 147 (45%) consecutive patients who underwent primary surgery with intent of cytoreduction. This approach was necessary in 60 of 94 (64%) patients with residual tumor less than 0.5 cm and contributed to achieving such a minimal residual disease in 36 of 38 (95%) stage IIB-IIIB and 58 of 109 (53%) IIIC-IV patients. Severe morbidity, but with no long-term sequelae, occurred in six (9%) patients. Before surgery, only ten (15%) of these patients had a performance status grade 0-1, 21 (32%) had grade 2, and 35 (53%) grade 3-4. After surgery, these figures were 52 (79%), 14 (21%), and 0, respectively. The 5-year survival rate was 37%, with a median survival and follow up time of 27 months (range 4-98) and 43 months, respectively. CONCLUSION: If the proper technique is used, complete pelvic cytoreduction is always feasible and morbidity is acceptable. In our series, it was necessary to approach the pelvis retroperitoneally in 64% of optimally cytoreduced patients, which suggests that this technique has an important clinical role in the treatment of patients with advanced ovarian cancer.

Surgery by minilaparotomy in benign gynecologic disease.

A new, minimally invasive technique for the management of benign gynecologic disease is proposed. With the patient in a steep Trendelenburg position, access to the pelvis is gained through a minimal suprapubic incision (4-9 cm) beneath the pubic hair line. The subcutaneous fat is incised in a cranial direction and the abdominal fascia is opened 2-3 cm above the skin incision. The peritoneum is opened manually and two or three Deaver retractors replace the traditional self-retaining retractor. Continuous repositioning of the retractors permits the operative window to be focused always on the surgical field. This technique can be performed only if the following criteria are met: use of narrow and light instruments; exteriorization of the affected organs; combined, unidirectional maneuvering of all the retractors; and prompt hemostasis by electrocoagulating forceps. Among 78 inpatients with benign gynecologic diseases who underwent surgical treatment with this approach, the feasibility rate was 96% and no intraoperative complications or severe postoperative morbidity were observed. Pelvic surgery by minilaparotomy is a feasible and safe approach in the treatment of benign gynecologic disease.

Long-term naltrexone treatment normalizes the pituitary response to gonadotropin-releasing hormone in polycystic ovarian syndrome.

OBJECTIVE: To investigate the influence of opioid system on the exaggerated LH response to GnRH test in the polycystic ovarian syndrome (PCOS). DESIGN: Pituitary stimulation (GnRH 100 micrograms) in a group of PCOS patients under basal condition and after 4 weeks of treatment with naltrexone. RESULTS: In the PCOS group, the naltrexone treatment determines a significant reduction of the LH response (calculated as the area under curve) to GnRH test, with a similar significant decrease of the LH:FSH. CONCLUSION: Naltrexone normalizes in the PCOS group the pituitary response to GnRH test, abolishing every statistical differences with the control group.

Effect of opiate receptor blockade on the insulin response to oral glucose load in polycystic ovarian disease.

In order to test the hypothesis that endogenous opiates are at least partially responsible for hyperinsulinaemia in patients with polycystic ovarian disease (PCOD), the effect of naloxone (an opiate receptor blocker) on the insulin response to oral glucose load (OGTT) was studied in 20 women with PCOD and 17 control subjects at days 5-8 of their follicular phase. After fasting overnight for 10-12 h, each woman received an i.v. bolus injection (2 mg) of naloxone or an equal volume of saline infusion followed by a constant infusion of naloxone or saline solution at a rate of 8 ml/h (1 mg/h of naloxone) for 5 h. OGTT (75 g) was performed 1 h after the bolus injection. The naloxone study was performed 48 h after the saline study. Naloxone did not modify the insulin response to OGTT in either group. When the data were related to the insulin response, in PCOD hyperinsulinaemic patients, naloxone significantly reduced (P less than 0.02) the insulin response to OGTT without any change in glycaemic response curves. In control and PCOD normoinsulinaemic patients, naloxone did not change significantly either the glycaemia or the insulin levels after OGTT. No change of gonadotrophin and steroid secretion was found in any patient receiving naloxone. In conclusion, endogenous opiates may play a significant role in hyperinsulinaemia in PCOD.
