One-year follow-up of tension-free vaginal tape (TVT) and trans-obturator suburethral tape from inside to outside (TVT-O) for surgical treatment of female stress urinary incontinence: a prospective randomised trial.

OBJECTIVES: To compare tension-free vaginal tape (TVT) and trans-obturator suburethral tape from inside to outside (TVT-O) for surgical treatment of stress urinary incontinence (SUI) for complications (primary end point) and success rate (secondary end point). METHODS: Seventy-two consecutive patients, with a mean age of 53.2 yr (range: 38-69 yr) and affected by SUI, were included in this randomised controlled trial. After preoperative assessment, patients were randomly allocated to the TVT or TVT-O procedure. Operative time, perioperative complications, and hospital stay were prospectively recorded. Cure of SUI was defined as no leakage of urine during the stress test at urodynamic testing at the 12-mo evaluation. The Wilcoxon signed rank sum test, Mann-Whitney U test, McNemar test, and Fisher exact test were used to verify statistical significance, set at p<0.05. RESULTS: All patients were evaluable at the 12-mo follow-up. The characteristics of patients were well balanced between groups after randomisation. The mean operative time was significantly shorter in the TVT-O group. Perioperative complications were significantly more common after the retropubic approach (5% and 27% in TVT-O and TVT groups, respectively, p<0.04). The groups did not differ significantly in intraoperative blood loss, hospital stays, and time to return to normal activities. Sixty-five patients (90%) were successfully treated for SUI 12 mo after the operation (89% and 91% for TVT-O and TVT groups, respectively). CONCLUSIONS: Both techniques appear to be equally effective in the surgical treatment of SUI. However, TVT-O had a shorter operative time and lower overall perioperative complication rate.

An unusual case of secondary fibrosarcoma after treatment for breast cancer.

BACKGROUND: Post-irradiation breast sarcoma is a rare and highly aggressive tumor, associated with poor prognosis. However, the mean latent periods reported for postradiation sarcomas after treatment of breast cancer ranges from 5 to 10 years. CASE: We present a rare case of fibrosarcoma of the axilla, diagnosed 23 months after breast surgery and irradiation for medullary poorly differentiated carcinoma, treated with wide local excision with resection of the serratus anterior muscle until pleural wall. CONCLUSION: This case confirm a possible early appearance of sarcoma in the irradiation field after radiotherapy. Thus, when a nodule appears in the irradiation field even if within 2 years after radiotherapy, physician should be alert for a possible sarcoma and wide biopsy with histologic confirmation is auspicable.

Pelvic lymphadenectomy for cervical carcinoma: laparotomy extraperitoneal, transperitoneal or laparoscopic approach? A randomized study.

OBJECTIVE: To compare transperitoneal, extraperitoneal and laparoscopic pelvic lymphadenectomy in terms of feasibility and morbidity in patients affected by cervical cancer undergoing radical hysterectomy. METHODS: Consecutive patients affected by stage IB-IIB cervical carcinoma scheduled for radical surgery entered the study. Patients were randomly assigned to transperitoneal (TPL), extraperitoneal (EPL) or laparoscopic pelvic lymphadenectomy (LPL). All patients underwent classical radical hysterectomy. Perioperative data were recorded. Follow up examinations were performed at the 15th, 30th and 60th day after surgery. RESULTS: 168 patients entered the study. The mean operative times were: 63+/-7.6, 54+/-6.7 and 75+/-8.4 min (TPL vs EPL P<0.001; EPL vs LPL P<0.001; TPL vs LPL P<0.001) for TPL, EPL and LPL respectively. The feasibility of the procedures, analyzed on an intention-to-treat basis, was 96%, 93% and 95% for TPL, EPL and LPL group respectively (P=ns). The average hospitalizations were: 5.6+/-0.9, 3.2+/-0.4 and 3.1+/-0.3 days (TPL vs EPL P<0.001; TPL vs LPL P<0.001) for TPL, EPL and LPL respectively. CONCLUSIONS: EPL and LPL are as feasible and effective as TPL and can be adequately performed with a reasonable complication rate. LPL showed a statistically significant longer operative time. However, both EPL and LPL can minimize some postoperative complications reducing length of stay.

Mechanical bowel preparation before gynecologic laparoscopy: a randomized, single-blind, controlled trial.

OBJECTIVE: To evaluate the use of mechanical bowel preparation (MBP) before gynecologic laparoscopy, using as the primary endpoint the appropriateness of the surgical field as judged by the surgeon. DESIGN: Prospective, randomized, single-blind clinical trial. SETTING: Academic department specializing in gynecologic surgery. PATIENT(S): One-hundred sixty-two patients scheduled for laparoscopy. INTERVENTION(S): The evening before laparoscopy, patients were randomized to either MBP with 90 mL of oral sodium phosphate (NaP) or no bowel preparation. MAIN OUTCOME MEASURE(S): Patient discomfort was evaluated with a visual analogue scale. Bowel preparation was evaluated by a surgeon (blind to bowel-preparation status) using a 5-point scale. Surgical difficulty, operating times, and postoperative complications were recorded. RESULT(S): Preoperative discomfort was significantly greater in the MBP group. No significant difference in the evaluation of the surgical field, operative difficulty, operative time, and postoperative complications was present between the two groups. CONCLUSION(S): Bowel preparation with oral NaP does not offer any significant advantage in patients undergoing laparoscopy for benign gynecologic conditions. In addition, MBP significantly increases preoperative discomfort.

Diagnostic open laparoscopy in the management of advanced ovarian cancer.

OBJECTIVE: Optimal primary cytoreductive surgery (OPCS) plus adjuvant chemotherapy (AC) represents the standard management for patients with advanced ovarian cancer (AOC). Recently, some authors have suggested the use of neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS) in patients with unresectable AOC. This study has been started to evaluate the role of diagnostic open laparoscopy (DOL) in predicting who are the best candidates to OPCS. METHODS: All patients newly diagnosed as affected by AOC were submitted to DOL in order to establish the possibility of OPCS considered as no residual tumor left after operation. Patients considered not susceptible of OPCS were submitted to three cycles of NACT, administered every 3 weeks (Carboplatin, targeted AUC = 6, plus paclitaxel 175 mg/mq), followed by IDS and adjuvant chemotherapy. RESULTS: From January 2000 to March 2004, 87 patients with AOC underwent DOL. Fifty-three patients (61%) were judged operable and therefore submitted to primary cytoreductive surgery (Group A). Optimal debulking rate in this group of patients was 96%. Thirty-four patients were judged affected by disease not cytoriducible to absent residual tumor and therefore scheduled for NACT-IDS-AC (Group B). Twenty-five patients were judged with partial clinical response and were therefore scheduled for IDS and AC. Optimal debulking rate (no residual tumor ) in Group B patients was 80%. No major perioperative complications, due to laparoscopy, occurred. All Group B patients received the first cycle of chemotherapy the day after DOL. In 34 patients (39%), an explorative laparotomy was avoided. With a median follow-up of 22 months (range 2-49 months), the proportions surviving were 87% and 60% in Group A and Group B patients, respectively. CONCLUSION: DOL could be considered a valid diagnostic tool in evaluating the extent of disease in AOC. Our data suggest that the use of DOL leads to decrease the rate of primary cytoreductive surgery for AOC; on the other hand, a higher optimal debulking rate (no residual tumor) at primary surgery is achieved.

Successful pregnancy after conservative surgery for stage IC ovarian cancer with serous borderline tumor on controlateral ovary: a case report.

BACKGROUND: In invasive ovarian cancer, fertility saving surgery is confined to early-stage and low-grade disease, and only few study reported sparing fertility up to FIGO stage IC ovarian cancer. CASE: We present a rare case of a 30-year-old woman affected by IC ovarian cancer with borderline tumor on controlateral ovary who underwent "conservative" debulking surgery followed by adjuvant chemotherapy. A spontaneous planned pregnancy occurred 5 years postsurgery. At 60-month follow-up, patients have no evidence of disease. CONCLUSIONS: Nowadays, preservation of ovarian function in women with tumors in early stage should be evaluated for conservative surgery. It is important to emphasize that patients selected for conservative surgery should have complete surgical staging. Careful follow-up is mandatory to ensure safety of this procedure.

Vaginal estrogen therapy and overactive bladder symptoms in postmenopausal patients after a tension-free vaginal tape procedure: a randomized clinical trial.

OBJECTIVE: To evaluate whether the frequency of overactive bladder (OAB) symptoms increases in menopause patients after a tension-free vaginal tape (TVT) procedure, and to determine if topical estrogen therapy can help prevent these symptoms. DESIGN: After undergoing a preoperative assessment, enrolled patients were randomly allocated to receive TVT plus postoperative vaginal estrogen therapy (ET group) or TVT without adjunctive medical treatment (No ET group). The pre- and postoperative assessments included: acquisition of a urogynecologic history with standardized questions regarding urinary function (including a 10-grade visual analogue scale score), urogynecologic clinical examination, and urodynamic assessment. Follow-up assessments were performed at 1, 3, and 6 months after surgery. RESULTS: Fifty-six of 59 patients were evaluable; 28 received topic vaginal estrogen after surgery (ET group) and 28 did not receive adjunctive medical treatment (No ET group). The overall OAB syndrome rate in menopause patients (No ET group) was 7% (2 of 28 patients) at baseline and 32% (9 of 28 patients) 6 months after surgery (P = 0.04). At the 6-month follow-up assessment, the incidence of urinary urgency was 4% (1 of 28 patients) and 29% (8 of 28 patients) in the ET and No ET groups, respectively (P = 0.01). Differences in frequency and nocturia were not statistically significant. Analysis of the visual analogue scale scores revealed that at the 6-month follow-up assessment, urgency significantly improved in the ET group compared with the No ET group (0.23 +/- 1.0 vs 2.30 +/- 3.7, respectively; P = 0.02). CONCLUSIONS: The TVT procedure seems to increase the frequency of OAB syndrome in menopause patients. Vaginal estriol therapy significantly reduces symptoms of urinary urgency, has a high rate of patient satisfaction, and can be used to treat postmenopausal women for at least 6 months after a TVT procedure.

Laparoscopic stripping of endometriomas: a randomized trial on different surgical techniques. Part II: pathological results.

BACKGROUND: The stripping technique for endometriomas excision has been reported to be associated with follicular loss. The objective of this trial was to evaluate the presence and nature of ovarian tissue adjacent to the endometrioma cyst wall obtained by stripping with different techniques. METHODS: Forty-eight patients with ovarian endometrioma were enrolled in two consecutive independent randomized trials. Two different techniques were analysed at the initial adhesion site (circular excision and subsequent stripping versus immediate stripping). Two different techniques were analysed at the ovarian hilus (stripping versus coagulation and cutting). Histology analysis was performed in three portions of the cyst wall (initial adhesion site, intermediate part of the specimen, ovarian hilus). RESULTS: Recognizable ovarian tissue was inadvertently excised together with the endometrioma cyst wall in most cases. At initial adhesion sites more ovarian tissue was removed with the circular excision technique (< 0.001). No significant difference in quality of ovarian tissue (number and type of follicles) was found between specimens obtained with different surgical techniques at the initial or at the final part of the procedure. At the initial adhesion site and at the intermediate part of the cyst wall, the ovarian tissue removed along with the endometrioma wall was mainly constituted by tissue with no follicles or only primordial follicles (60% and 48% of the specimens from the initial part with both techniques, and from the intermediate part, respectively, had no follicles or only primordial follicles). Close to the ovarian hilus the ovarian tissue removed along with the endometrioma wall mostly consisted of tissue which contained primary and secondary follicles (69% of the cases, combining the two groups). CONCLUSIONS: Ovarian tissue is inadvertently excised together with the endometrioma wall in most cases. The excised tissue is at normal functional development stages only near the ovarian hilus. The different techniques used do not influence significantly the quality of the resected tissue.

Laparoscopic stripping of endometriomas: a randomized trial on different surgical techniques. Part I: clinical results.

BACKGROUND: Laparoscopic surgery has become the gold-standard treatment for ovarian endometriomas. The objective of this trial was to evaluate different procedures for the laparoscopic excision of ovarian endometriomas with the stripping technique. METHODS: Forty-eight patients with ovarian endometrioma were enrolled in two consecutive independent randomized trials. Two different techniques were analysed at the initial adhesion site (circular excision and subsequent stripping versus immediate stripping). Two different techniques were analysed at the ovarian hilus (stripping versus coagulation and cutting). Operative time and technical difficulties were prospectively evaluated. Histological analysis was performed in three portions of the cyst wall and the results of the histologic study are reported separately. RESULTS: At the initial part of the stripping procedure, the technique of circular excision and subsequent stripping appeared to be more easily performed than the technique of direct stripping (P < 0.01), although operative times were comparable between the two techniques. At the hilus, the two techniques utilized appeared to be comparable both for easiness of procedure and operating times. CONCLUSIONS: In this prospective, randomized study, different techniques used during the stripping procedure appeared to be comparable in terms of operative times and complications. One technique used at the beginning of the procedure (circular excision followed by stripping) was easier to perform.

Single agent cisplatin chemotherapy in surgically resected vulvar cancer patients with multiple inguinal lymph node metastases.

OBJECTIVE: The aim of this study was to evaluate acute and long-term morbidity, recurrence rate, and overall survival in patients with multiple groin lymph node metastases treated with postoperative chemotherapy. METHODS: Patients affected by FIGO stages III, IVA, and IVB (pelvic lymph nodes only) submitted to surgery were then treated with four cycles of cisplatin 100 mg/m(2) given 21 days apart. Toxicity, overall, and disease-free survival were evaluated. RESULTS: Fourteen patients were evaluated. Median patients age was 58 (range 48-82). Median performance status was 0 (0-2). All patients completed the treatment. No treatment-related deaths occurred. Only two patients suffered from grade 4 neutropenia during chemotherapy. Three patients suffered from long-term severe lymphedema. Four patients suffered a disease recurrence. Three of these patients were subjected to surgery with no severe postoperative complications. Two of the latter patients are still alive. At a median follow-up of 57.5 months (range 23-79 months) actuarial 3-year overall survival and progression-free survival are 86% and 71%, respectively. CONCLUSIONS: In patients affected by vulvar cancer with multiple lymph node metastases, radical surgery followed by chemotherapy is a feasible strategy, with an acceptable short- and long-term complication rate. Results in terms of overall survival and disease-free survival are promising. Furthermore, due to absence of local long-term tissue toxicity, this strategy allows physicians to surgically treat regional lymph node recurrence safely.

Tailoring the parametrectomy in stages IA2-IB1 cervical carcinoma: is it feasible and safe?

OBJECTIVE: Several authors have proposed the use of a less aggressive surgery (i.e., modified or type 2 radical hysterectomy) for patients affected by early stages cervical carcinoma. However, little attention has been given to the evaluation of adverse prognostic factors before selecting the surgical approach. The aim of this study is to evaluate the feasibility and safety of tailoring parametrectomy on the basis of specific prognostic factors preoperatively assessed. METHODS: Patients with cervical carcinoma FIGO IA2-IB1 entered the study. Eligibility criteria were: age < 75 years, no contraindications for surgery, informed consent, expected cooperation for follow-up. Tumor size was preoperatively assessed by pelvic examination under anesthesia and pelvic MRI. Patients were submitted to systematic lymphadenectomy of superficial obturator, external iliac, and interiliac nodes by laparotomy or laparoscopy. Lymph nodes were sent for frozen section. Node-negative patients were submitted to modified radical hysterectomy (type 2). Patients with nodal metastases underwent classical radical hysterectomy (types 3-4) and systematic pelvic and aortic node dissection up to the inferior mesenteric artery. Survival rates were calculated using the Kaplan-Meier product-limit method. RESULTS: Eighty-three patients were enrolled in the study. Among these, 63 patients were node-negative at frozen section, and therefore submitted to modified radical hysterectomy (Group A); 20 patients were found having nodal metastases intra-operatively, and therefore submitted to classical radical hysterectomy (Group B). Median follow up was 30 months. Five years overall survival was 95% for Group A, and 74% for Group B. CONCLUSIONS: Pre-treatment evaluation of adverse prognostic factors in patients affected by cervical cancer FIGO stages IA2-IB1 is feasible and mandatory to determine if a less radical surgery is applicable and safe.

Transurethral polydimethylsiloxane implantation: a valid option for the treatment of stress urinary incontinence due to intrinsic sphincter deficiency without urethral hypermobility.

PURPOSE: In this study we evaluated the 5-year followup results of periurethral polydimethylsiloxane (PDMS) injection for female stress urinary incontinence (SUI) secondary to intrinsic sphincter deficiency (ISD) without hypermobility of the vesicourethral junction. MATERIALS AND METHODS: A total of 61 female patients with ISD were enrolled in this prospective, observational study. Preoperative and postoperative assessment included a standardized urogynecologic history with questions regarding urinary function, urogynecologic and neurological physical examination, and urodynamic assessment. All patients underwent periurethral PDMS injection. Patient followup was performed 1, 6, 12, 24, 36, 48 and 60 months after surgery. RESULTS: At 60 months after injection the SUI cure rate was 18%, the improvement rate was 39% and the failure rate was 43%. The success rate was 57%. Of the patients 45 (74%) subjectively improved with respect to the severity of urinary incontinence. No postoperative early complications were found. At 60 months of followup only minor complications were reported (11%). CONCLUSIONS: Careful patient selection by optimal diagnostic tools are essential for maximizing the results of urethral bulking agent therapy. PDMS injection in women with SUI due to ISD with limited urethral mobility is a valid, minimally invasive procedure.

Long-term bladder function in patients with locally advanced cervical carcinoma treated with neoadjuvant chemotherapy and type 3-4 radical hysterectomy.

BACKGROUND: The objective of the current study was to evaluate the incidence of long-term bladder dysfunction after type 3-4 radical hysterectomy in patients with locally advanced cervical carcinoma treated with neoadjuvant chemotherapy (NACT). METHODS: A case-control study was conducted to evaluate the occurrence of long-term bladder dysfunction in 76 patients with International Federation of Gynecology and Obstetrics Stage IB-IIA (> 4 cm), Stage IIB, and Stage III cervical carcinoma who underwent type 3-4 radical hysterectomy after NACT. Preoperative assessment included acquisition of a standardized urogynecologic history, evaluation of severity of urinary incontinence symptoms, maintenance of a 3-day voiding diary, pelvic examination, urogynecologic physical examination, urodynamic assessment, and estimation of hydronephrosis. Follow-up was carried out at least 12 months after surgery. RESULTS: Urinary symptoms (sensory loss, difficult micturition, severe urinary incontinence) were reported by 20 patients (26%). Eighteen patients (24%) had a normal urodynamic profile, 16 patients (21%) had detrusor overactivity, 22 patients (29%) had urodynamic stress incontinence, 2 patients (2%) had aconctractile detrusor, and 18 patients (24%) had mixed urinary incontinence. The length of vagina removed was significantly greater among patients who had detrusor overactivity and mixed urinary incontinence compared with patients who had a normal diagnosis. CONCLUSIONS: The observed rate of bladder dysfunction was higher than the corresponding rate reported in the literature (76%). Three main disturbances were found: detrusor overactivity (21%), mixed urinary incontinence (24%), and de novo stress incontinence (21%). Detrusor overactivity was related to a prevalence of hypertonic bladder. Among patients who underwent type 4 radical hysterectomy, the extent of caudal resection of rectovaginal ligaments and vaginal tissue was found to be more strongly associated with bladder dysfunction than was the extent of lateral parametrial resection. Despite the fact that 76% of patients had abnormal urodynamic parameters, most patients were satisfied with their voiding condition.

Vesical dysfunctions after radical hysterectomy for cervical cancer: a critical review.

Functional disorders of the lower urinary tract are the most common long-term complications following radical surgery for cancer of the uterine cervix (8-80%). These disturbances were associated to the partial interruption of the autonomic fibers innervating the bladder during the resection of anterior, lateral and posterior parametrium and vaginal cuff. The pathophysiology of these changes is actually debated. The nature of the surgical damage appears to be a decentralization rather than a complete denervation and bladder dysfunctions may be either the unmasking of intrinsic detrusor activity, characterized by a loss of beta-adrenergic innervation and a consequent alfa-adrenergic hyperinnervation or the influence of remaining sympathetic innervation. No data on long-term bladder function in patients who underwent class 4 radical hysterectomy have been reported. In our experience on long-term vesical function in 38 patients with locally advanced cervical cancer treated with neoadjuvant chemotherapy and 4 Piver type radical hysterectomy, urinary symptoms were reported in 11 patients (29%), while a normal urodynamic finding was recorded in only nine patients (24%). The most common bladder dysfunction was the storage dysfunction (47%). The voiding dysfunction was present in one patient (3%) and stress urinary incontinence in 20 patients (53%). The parametrial and vaginal resections were compared among the urodynamic diagnosis The size of lateral parametria measured on the giant sections did not differ among the groups of urodynamic diagnosis, while the length of vagina removed was significantly longer in patients with detrusor dysfunctions (storage and voiding dysfunctions) than in patients with normal diagnosis or genuine stress incontinence.

Subcutaneous drainage versus no drainage after minilaparotomy in gynecologic benign conditions: a randomized study.

OBJECTIVE: The purpose of this study was to determine the outcomes of subcutaneous drainage in patients who are affected by benign gynecologic diseases that are treated by a Kustner's minilaparotomy incision. STUDY DESIGN: We performed a randomized controlled study with 72 patients who underwent operation for benign gynecologic disease. Patients were assigned intraoperatively to two groups: group A (36 patients) had a closed drainage system and group B (36 patients) had no drainage. Historic data, clinical and surgical characteristics, and perioperative complications were recorded prospectively. Postoperative care data, surgical incision complications, and hospital stay were analyzed. Patients were to be seen 4 weeks after the operation to assess wound healing. RESULTS: No patients had intraoperative complications or blood transfusions. A significant difference was observed between the drainage versus no-drainage groups regarding postoperative complications and hospital stay (P =.001, both groups). No patients had surgical complications at 4 weeks after the last operation. CONCLUSION: Our data suggest that routine prophylactic subcutaneous drainage is indicated in patients who undergo Kustner's minilaparotomy incision for benign gynecologic operation. Drains significantly prevent wound complications and reduce hospital stay.
