Secondary cytoreductive surgery in patients with platinum-sensitive recurrent ovarian cancer.

BACKGROUND: Secondary surgical cytoreduction (SCR) represents a promising therapeutic strategy for patients affected by ovarian cancer disease recurrence. The aim of this prospective observational trial was to analyze the role of SCR in patients with platinum-sensitive ovarian cancer. METHODS: Patients with platinum-sensitive ovarian cancer underwent SCR by a single surgical team. Clinical and oncologic data were prospectively recorded. A total of 47 patients underwent SCR from 1999 to 2003. RESULTS: The mean operating time was 210 minutes, and mean blood loss was 500 mL. The most frequent surgical procedures carried out were splenectomy, lymphadenectomy, bowel resection, and extensive peritonectomy. Optimal cytoreduction was achieved in 41 patients. Thirty-seven patients had no visible tumor at the end of SCR. Overall median survival was 49 months. Patients who achieved optimal residual disease had a median survival of 61 months, whereas patients who had residual disease >1 cm had a median survival of 19 months. CONCLUSIONS: Positive CA-125 (cancer antigen 125) was identified as a negative prognostic factor at multivariate analysis. After careful selection, optimal cytoreduction can be achieved in most patients who are subjected to SCR with acceptable morbidity. Residual tumor and CA-125 represent the most important prognostic factors.

Histologic analysis of endometriomas: what the surgeon needs to know.

OBJECTIVE: To evaluate by thorough pathologic analysis the histologic features of the endometrioma wall excised at laparoscopy. DESIGN: Prospective series of consecutive patients. SETTING: Tertiary care, university hospital. PATIENT(S): Fifty-nine patients with ovarian endometriomas. A total of 70 cysts were examined. INTERVENTION(S): Patients underwent operative laparoscopy with the stripping technique for excision of the ovarian endometrioma. MAIN OUTCOME MEASURE(S): A thorough histologic examination was performed on the entire cyst wall specimen. RESULT(S): Histologic examination confirmed the endometriotic nature of the cyst in 100% of the cases. The inner wall of the endometrioma was covered by endometriotic tissue on 60% of the surface. The mean cyst wall thickness was 1.4 mm. The mean value of maximal depth of endometriosis penetration in the endometrioma wall was 0.6 mm. In 99% of the cases the maximal penetration of the endometriotic tissue was <1.5 mm. CONCLUSION(S): In the present study, we demonstrate that the endometrioma wall contains endometriotic tissue in 100% of the cases. However, the endometriotic tissue may cover the inner cyst wall for a surface that varies between 10% and 98% of the entire wall (median value 60%). This tissue may reach a depth of 2 mm, but for most of the surface it does not penetrate >1.5 mm. These histologic data may help the gynecologic laparoscopist select the surgical approach that maximally preserves healthy ovarian tissue.

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.

Distal phalange necrosis: a severe manifestation of palmar plantar erythrodysesthesia.

Palmar plantar erythrodysesthesia is a cutaneous drug reaction induced by chemotherapy. We present a case of a patient with neurosensorial deficit affected by ovarian cancer who experienced a painless necrosis of a distal phalange of the hand during treatment with pegylated liposomal doxorubicin. Palmar plantar erythrodysesthesia may be underestimated by physicians in paucisymptomatic patients.

Minilaparotomy versus laparoscopy in the treatment of benign adnexal cysts: a randomized clinical study.

OBJECTIVE: To determine advantages and disadvantages of minilaparotomy and laparoscopy in managing patients affected by benign adnexal masses. STUDY DESIGN: Prospective, randomized, clinical trial on 127 patients affected by adnexal cysts. Patients were submitted to adnexal surgery through a laparoscopic or minilaparotomy approach on a random basis. RESULTS: Hundred and twenty-seven patients were enrolled in the study and randomly assigned to laparoscopy (63 patients) or minilaparotomy (64 patients). Characteristics of the patients and of the cysts were homogeneous between the two groups. No significant differences between the two groups were recorded in terms of operative time, intraoperative complications, ileus, length of stay and recovery time. The intraoperative rupture rate of the cyst was significantly higher in the laparoscopy group only in a subgroup of patients affected by cysts greater than 7 cm in diameter (p=0.01). Three patients randomized to laparoscopy required conversion to laparotomy. Concerning postoperative outcomes, postoperative pain and minor complications were significantly less in patients undergoing laparoscopy (p=0.001 and 0.04). CONCLUSIONS: Operative laparoscopy appears to be the preferable approach for the management of adnexal cysts. Minilaparotomy can be considered a mini-invasive approach as well, with acceptable operative and postoperative outcomes, and is a suitable alternative in case of contraindications to laparoscopy.

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.

Splenectomy during secondary cytoreduction for ovarian cancer disease recurrence: surgical and survival data.

BACKGROUND: Ovarian cancer disease recurs predominantly in the abdomen, with the spleen usually involved as part of a vast spread of upper-abdominal disease or, less frequently, as an isolated site of disease recurrence. Very few reports are available in the literature on the outcome of patients subjected to splenectomy during secondary cytoreduction. The aim of this study was to identify prognostic factors and to review surgical and clinical data in order to identify those patients who would benefit the most from splenectomy during secondary cytoreduction. METHODS: This was a retrospective review of platinum-sensitive recurrent epithelial ovarian cancer patients who underwent splenectomy as part of secondary cytoreduction. Surgical and survival data were recorded. RESULTS: Twenty-four patients were identified. Multiple site disease recurrence was observed in 15 patients. The spleen was involved at the hilus in 12 patients; surface and intraparenchymal metastases were equally present. Optimal cytoreduction was achieved in all patients. At a median follow-up of 30 months, median progression-free and overall survival from the time of secondary surgery were 34 and 56 months, respectively. Overall survival was significantly correlated to residual disease at secondary surgery, disease-free survival, consolidation chemotherapy, and type of adjuvant therapy. CONCLUSIONS: Splenectomy as part of secondary cytoreduction is a feasible and safe procedure. Secondary cytoreduction in selected groups of patients is confirmed to be associated with high long-term survival rates even when aggressive surgery of the upper abdomen is required.

Ovarian cancer, diagnosed with PET, with bilateral inguinal lymphadenopathy as primary presenting sign.

BACKGROUND: Ovarian cancer groin lymph nodes metastases are rare. Only one case of disease spread isolated to the groins has been reported in the English literature. We report the case of a patient with bilateral inguinal lymphadenopathy due to tumor metastases and in which tumor origin was diagnosed using [(18)F]fluorodeoxyglucose positron emission tomography (PET). CASE REPORT: This is the first case of bilateral groin lymph nodes as sole site of metastases from ovarian cancer. Primary origin was identified using PET. CONCLUSIONS: In rare cases, the ovaries can directly metastasis to the groin even in a relatively initial tumor growth phase. PET may play a role in the diagnosis of occult ovarian tumors.

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.

Ringer's lactate solution remains in the peritoneal cavity after laparoscopy longer than expected.

OBJECTIVE: To evaluate by serial ultrasound scans how long a Ringer's lactate instillation remains in the peritoneal cavity after laparoscopy. DESIGN: Prospective, randomized, double blind, clinical trial. SETTING: Tertiary care, university hospital. PATIENT(S): Thirty-six patients undergoing diagnostic or minor operative laparoscopy. INTERVENTION(S): At the end of laparoscopy, the patients were tilted to an anti-Trendelenburg position and all fluid was aspirated. The patients were then randomized to receive an instillation of 300 mL of Ringer's lactate or no fluid instillation. Serial transvaginal ultrasound scans were performed at the end of surgery and at 24, 48, and 96 hours after the surgery. MAIN OUTCOME MEASURE(S): Through direct measurements of scalar fluid volumes instilled in the operating room and real-time ultrasound comparisons, an empiric formula was calculated to correlate actual intraperitoneal volumes to ultrasonically derived measurements of fluid pockets. With this formula, the volume of intraperitoneal fluid at 24, 48, and 96 hours after surgery was calculated. RESULT(S): Twenty-four hours after surgery, a mean volume of 184 mL was present in the Ringer's lactate group versus 46 mL in the control group. At 48 hours after surgery, the mean volumes were 78 mL versus 30 mL, respectively. No statistically significant differences were found after 96 hours. CONCLUSION(S): Peritoneal absorption of instilled crystalloids is traditionally reported to be 30 to 60 mL/hour. We report detecting statistically significant amounts of fluid at 24 and 48 hours after surgery, after infusion of 300 mL of Ringer's lactate. This suggests that fluid remains in the peritoneal cavity longer than traditionally believed.

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.

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.

Ultrasonographic evaluation of postoperative ovarian cyst formation after laparoscopic excision of endometriomas.

STUDY OBJECTIVE: To evaluate, by means of serial transvaginal ultrasound (US) examinations, the ovary after laparoscopic excision of endometriomas with the stripping technique. DESIGN: Prospective, controlled, single-blind clinical trial (Canadian Task Force classification II-1). SETTING: Tertiary care university hospital. PATIENTS: Forty-seven patients, from 21- to 35-years old, undergoing laparoscopic excision of a monolateral ovarian endometrioma. INTERVENTION: The patients underwent serial US scans performed by a blinded observer during the first, third, and sixth menstrual cycle after surgery. MEASUREMENTS AND MAIN RESULTS: At the first follow-up US examination, an abnormal finding, namely the presence of an ovarian cyst on the operated ovary, was diagnosed in five of 47 patients (10.6%; p = .03 when compared with the nonoperated ovary). In the remaining 42 patients (89.4%), no gross abnormalities were evident. No differences were present between the two ovaries as to ovarian volume or follicular development pattern. During the third follow-up US, in 47 patients (100%) no gross abnormalities were present. CONCLUSION: The US follow-up of ovaries operated on for endometriomas by laparoscopy demonstrates that the evidence of an ovarian cyst in the early postoperative period is not an uncommon event. This finding, occurring in approximately 10% of cases, seems to be a transient one occurring during ovarian healing after surgery, since no evidence of such anomaly was present on subsequent US scans. Therefore, treatment for US evidence of recurrence of an ovarian endometrioma should be deferred for at least 3 to 6 months if the diagnosis of recurrence is made in the early postoperative period. Apart from this finding, the operated ovary is indistinguishable from the contralateral one, even 1 month after surgery.

Guidelines of how to manage vesicovaginal fistula.

Vesicovaginal fistulas are among the most distressing complications of gynecologic and obstetric procedures. The risk of developing vesicovaginal fistula is more than 1% after radical surgery and radiotherapy for gynecologic malignancies. Management of these fistulas has been better defined and standardized over the last decade. We describe in this paper the success rate reported in the literature by treatment modality and the guidelines used at our teaching hospitals, University of Rome Campus Biomedico and University of Miami School of Medicine. In general, our preferred approach is a trans-vaginal repair. To the performance of the surgical treatment, we recommend a minimum of a 4-6 week's wait from the onset of the fistula. The vaginal repair techniques can be categorized as to those that are modifications of the Latzko procedure or a layered closure with or without a Martius flap. The most frequently used abdominal approaches are the bivalve technique or the fistula excision. Radiated fistulas usually require a more individualized management and complex surgical procedures. The rate of successful fistula repair reported in the literature varies between 70 and 100% in non-radiated patients, with similar results when a vaginal or abdominal approach is performed, the mean success rates being 91 and 97%, respectively. Fistulas in radiated patients are less frequently repaired and the success rate varies between 40 and 100%. In this setting many institutions prefer to perform a urinary diversion. In conclusion, the vaginal approach of vesicovaginal fistulas repair should be the preferred one. Transvaginal repairs achieve comparable success rates, while minimizing operative complications, hospital stay, blood loss, and post surgical pain. We recommend waiting at least 4-6 weeks prior to attempting repair of a vesicovaginal fistula. It is acceptable to repeat the repair through a vaginal approach even after a first vaginal approach failure. In the more individualized management of fistulas associated with radiation, the vaginal approach should still be considered.
