Rectus abdominis myocutaneous flaps for neovaginal reconstruction after radical pelvic surgery.

The objective of this article is to compare the flap-specific complications associated with vertical (VRAM) and transverse (TRAM) rectus abdominis myocutaneous flap vaginal reconstructions performed during radical pelvic procedures. A retrospective chart review was performed to identify all patients who underwent VRAM and TRAM neovaginal reconstructions performed on the Gynecologic Oncology Service at Duke University Medical Center. Flap-specific complications were compared between the two techniques. From 1988 to 2003, 14 VRAM and 18 TRAM flap neovaginal reconstructions were performed on 32 women during the course of 22 (68%) total pelvic exenterations, 8 (25%) partial exenterations, and 2 (6%) radical vulvovaginectomies. Twenty-eight (88%) patients had been previously treated with radiation therapy or concurrent chemoradiation. Associated procedures included continent urinary conduit in 21 (66%), rectosigmoid reanastomosis in 8 (25%), and intraoperative or postoperative sidewall radiation therapy in 7 (22%) of patients. Overall median survival was 14 months (range: 2-week postoperative death to 65 months), with two (6%) acute postoperative mortalities. Fifteen flap-specific complications occurred in 12 (38%) patients, with no significant differences in flap type. Abdominal wound complications included four (12%) superficial wound separations, while one (3%) patient had a fascial dehiscence associated with complex fistulas that contributed to her death, but no patient developed incisional hernia. One patient each developed > 50% flap loss after TRAM and < 50% flap loss after VRAM flap, respectively. Four (12%) patients developed vaginal stricture or stenosis, two (6%) required percutaneous drainage of pelvic abscess or hematoma, and two (6%) developed rectovaginal fistula. Univariate analysis revealed a trend for increasing flap loss with body mass index > 35 (P = 0.056, Fisher exact two-tailed test), but there were no significant associations with other patient characteristics or flap-specific complications. Thirteen (62%) of 21 patients who survived >12 months reported coitus. Both VRAM and TRAM are reliable techniques for neovaginal reconstructions after radical pelvic surgery and have a similar distribution of flap-specific complications involving the donor and recipient sites.

Aggressive surgical treatment for patients with T4 rectal cancer.

OBJECTIVE: To investigate the outcome of surgical treatment for patients with T4 rectal cancer and to evaluate prognostic factors influencing 5-year disease-free survival. PATIENTS: Of 1600 rectal cancers seen between 1985 and 1998, there were 197 patients with T4 of whom 128 were treated with curative intent. In this retrospective study organ invaded, the type of treatment and outcome were analysed. RESULTS: Of the 128 patients, 89% had visceral involvement and 11% had pelvic wall involvement. The most frequently involved organ was bladder, followed by prostate and vagina. Low anterior resection was performed in 52, abdomino-perineal resection in 35 and total pelvic exenteration in 41 patients. Of 81 with urinary tract invasion, 50% were treated with bladder-sparing surgery. Pathological examinations showed bladder involvement in only 44 of these and overall 5-year disease-free survival was 57%. Multivariate analysis revealed that body mass index, lymph node metastasis and inflammatory reaction were significant predictors of survival. CONCLUSION: Completeness of resection is the essential factor influencing oncological outcome.

Pudendal thigh fasciocutaneous flaps for vaginal reconstruction in gynecologic oncology.

The pudendal thigh is a sensate fasciocutaneous flap supplied by the posterior labial artery. We report on the results of pudendal thigh flaps used for vaginal reconstruction in eight patients at the time of pelvic exenteration (6) and radical vaginectomy (2). Patients were interviewed and results were assessed 5 to 19 months after surgery. The flaps were raised in the thigh creases just lateral to the hair bearing area of the labia majora and included skin, subcutaneous tissues, deep fascia of the thigh, and the epimysium of the adductor muscles. Flap sizes varied from 9 x 4 cm to 15 x 6 cm. Bilateral flaps were used in seven patients. The flaps were technically easy to perform. Partial (apical) flap necrosis occurred in four patients. One patient developed complete necrosis of bilateral flaps, followed by an enterovaginal fistula. One patient whose flaps did not necrose developed a rectovaginal fistula at the site of rectal reanastomosis. The functional results are disappointing. The only patient having successful vaginal intercourse had a unilateral flap reconstruction following lower vaginectomy in a nonirradiated pelvis. No patient with bilateral flaps or prior pelvic irradiation has had successful coitus. Other long-term sequelae include vulvar pain (2), chronic vaginal discharge (2), hair growth (4), and protrusion of the flaps (2). These vulvovaginal symptoms discourage patients and their partners from genital contact. Breaching the integrity of the vulva to construct a neovagina that is likely to be unsuitable for sexual intercourse may deprive women of their only potential for normal genital sexual responsiveness. Techniques of vaginoplasty require continued assessment.

Cancer of the vulva: a review.

Localized carcinoma of the vulva in situ can be treated by wide local excision and continued close observation. Skinning vulvectomy, with or without subsequent skin grafting, is now well accepted as a treatment of Multifocal preinvasive disease. Microinvasive carcinoma of the vulva, on the other hand, is not treated with vulvectomy alone since the regional lymph nodes must be accurately assessed. The currently accepted treatment of invasive carcinoma of the vulva is radical vulvectomy and bilateral groin lymph node dissection. No longer is pelvic lymph node dissection to be considered a routine part of this therapy but is included only under specific circumstances. On rare occasion a more radical procedure such as anterior or posterior pelvic exenteration is considered appropriate therapy when the geographic location of the tumor requires this approach. The treatment of recurrent disease is influenced by its extent and location and must be tailored for the individual patient. Palliative vulvectomy is still used as a treatment of the far advanced disease in an attempt to improve personal and social hygiene, as well as to control serious infection and to prevent localized hemorrhage. The role of x-ray therapy in the treatment of carcinoma of the vulva is discussed.

Multiorgan resections for advanced colorectal cancer.

BACKGROUND: A retrospective review is presented of a single institution's experience with multivisceral resections for locally-advanced colorectal cancer. MATERIALS AND METHODS: Twenty-eight patients, who had undergone RO multiorgan resection, were identified from the database of a total of 1150 patients operated on for colorectal carcinoma in the years 1995-2005 at a single center. There were twelve total pelvic exenterations and 16 patients had undergone en bloc primary tumor resection with adherent organs, such as the spleen, diaphragm, pancreas, stomach, kidney, etc. The patients were followed-up according to a standard protocol. RESULTS: The post-operative mortality was 7%, the average follow-up 21.6 months and the 5-year survival 45%. CONCLUSION: Our results confirmed that, in the case of invasion of colorectal cancer to the adjacent intra-abdominal organs or structures, multiorgan resection 'offers the only chance of potentially-curative treatment.

Rectus abdominis myocutaneous and myoperitoneal flaps for neovaginal reconstruction after radical pelvic surgery: comparison of flap-related morbidity.

PURPOSE: To compare flap-specific complications of rectus abdominis myocutaneous (RAM) and myoperitoneal (RAMP) flap neovagina reconstructions performed concurrently with radical pelvic procedures. MATERIALS AND METHODS: Retrospective single institution chart review of all patients with RAM or RAMP flap neovaginal reconstructions performed on a Gynecologic Oncology service, 1988-2003. Analysis for associations with flap-specific morbidity was performed. RESULTS: Neovaginal reconstructions comprised 32 RAM and 7 RAMP flaps. Twenty-two (69%) RAM patients underwent total pelvic exenteration compared to 1 (14%) RAMP patient (P < 0.013). Overall, 33 (85%) of the patient population had previously been treated with radiation. Flap-specific complications developed in 12 (32%) RAM versus 4 (57%) of the RAMP patients (P > 0.1). Donor site complications and incisional hernias were increased in RAMP patients (both P < 0.03), with trends for increasing risk of vaginal stricture/stenosis and superficial wound separations (both P < 0.1). Complete vaginal stenosis developed in only 1 (3%) RAM versus 3 (43%) RAMP patients. Furthermore, 3 RAMP patients developed complete stenosis when the vaginal defect was circumferential and involved >65% of the vagina while this did not occur in 22 similar RAM patients (P < 0.0005). Only patients with partial longitudinal defects maintained vaginal patency after RAMP flap. Fifteen (58%) of 26 patients surviving >12 months reported coitus, with no significant difference between the groups. CONCLUSIONS: When there is circumferential loss of the upper 2/3 of the vagina. RAMP flaps are not suitable for neovaginal reconstruction after radical pelvic surgery because of an increased risk of vaginal stenosis compared to RAM flaps. Patients with partial longitudinal vaginal defects, however, may have successful neovaginal reconstruction with RAMP flaps.

Prostatic carcinosarcoma 15 years after combined external beam radiation and brachytherapy for prostatic adenocarcinoma: a case report.

A 65-year-old man with a history of combined pelvic external beam radiation therapy (EBRT) and brachytherapy for prostatic adenocarcinoma 15 years prior underwent total pelvic exenteration for presumed rectal sarcoma with prostatic invasion. Pathology revealed carcinosarcoma of prostatic origin. This patient exhibited the longest reported interval between initial presentation with prostatic adenocarcinoma and development of carcinosarcoma. This case is also the first reported case of prostatic carcinosarcoma occurring after combined EBRT and brachytherapy. The increasing use of such combination high-dose radiation therapy may potentially lead to an increased incidence of secondary malignancies such as prostatic carcinosarcoma in the future.

Sigmoid impaction secondary to urinary stones: case report and review of literature.

BACKGROUND: This is the first case report of a Miami pouch sigmoid fistula developing passage of urinary stones resulting in the presentation of constipation secondary to impaction. CASE REPORT: A 49-year-old woman who developed a recurrence of invasive squamous cell cervical carcinoma 1 year after pelvis radiation. She then underwent anterior pelvic exenteration and creation of a Miami pouch. Approximately 14 years after the primary radiation therapy and 13 years after the creation of the exenterative procedure, the patient developed a Miami pouch sigmoid fistula. The decision was made at this time to repair the fistula and remove the urinary stones from the sigmoid colon. Postoperatively, the patient remained continent using intermittent catheterization of the pouch and there was no evidence of recurrence of the cancer. CONCLUSION: Conservative management of urinary reservoir complications should always be considered before surgical intervention is attempted. When indicated, surgical management should not be delayed.

Improved technique of tubeless cutaneous ureterostomy and results of permanent urinary diversion.

An improved technique of tubeless cutaneous ureterostomy through a single stoma was devised by modifing the traditional cutaneous ureterostomy. Using this method, urinary diversions were performed on 12 cases with malignancies: 6 had radical cystectomy and the other 6 had pelvic exenteration. Normal bilateral ureters were observed in 11 cases in preoperative intravenous pyelography. Stomal stenosis was found in 1 case (8.3%) requiring operative stomal revision. Generally satisfactory results were obtained. This method could lower the incidence of complications. A long-term follow-up is needed, but 2 cases who have survived for more than 4 years since the operation have shown excellent results. It was thought that it would be difficult to perform tubeless cutaneous ureterostomy on normal-sized ureters, but our clinical results indicate that this method may be able to provide permanent urinary diversion.

Vaginal reconstruction with rectus abdominis myocutaneous flap: CT findings.

The distally based rectus abdominis myocutaneous flap is used in a new technique for vaginal reconstruction after pelvic exenteration for malignant disease. We identified 27 patients who underwent this procedure, of whom eight had a total of 14 postoperative CT scans and two CT-directed biopsies. The myocutaneous flap appeared as a unilateral arcuate band of soft tissue extending from the linea alba to the rectal fascia or sacrum. Additional CT findings included asymmetric thinning of the ventral abdominal wall (7/8), fluid collections (2/8), vaginal breakdown (1/8), presacral soft-tissue thickening (6/8), and tumor recurrence (3/8). The postoperative CT scan reflects the altered anatomy produced by the surgery. Complications and recurrent disease can be recognized as deviations from the normal postoperative appearance.

[Body image in gynecologic patients before and after radical surgery].

After radical gynecologic surgery women are faced with therapy-induced changes of their body. Since 1995, the body images of women who undergo pelvic exenteration, Wertheim-Meigs-operation or hysterectomy are assessed preoperatively and four and twelve months postoperatively. The aim of this multidimensional prospective study is to get basic information for effective counselling and support. One year after hysterectomy women state to have a normal body image. Cancer patients feel less attractive, less self-confident and more discontented in sexuality depending on therapy-induced changes of their bodies. These women could profit from problem-related preoperative counselling. Postoperative counselling offers will be helpful to support women in the process of acceptance of bodily changes and in the reorganisation of their sexual life.

[A case of liver metastases of rectal carcinoid successfully treated with hepatic arterial infusion of methotrexate and 5-fluorouracil].

Standard therapy for liver metastasis from colorectal carcinoid remains controversial because of the rarity of the disease. We report herein a case of rectal carcinoid with multiple liver metastasis successfully treated with hepatic arterial infusion of methotrexate (MTX) and 5-fluorouracil (5-FU). A 65-year-old woman underwent posterior pelvic exenteration and hepatic arterial catheterization for rectal carcinoid involving the vagina associated with multiple liver metastases. Hepatic arterial infusion of MTX (50 mg/body) and 5-FU (500 mg/body) was started and repeated with a frequency of twice a week postoperatively. After 40 cycles of this chemotherapy, all but the largest metastatic lesion disappeared, and the largest decreased in size by 53%. The partial response was maintained for 7 months. Her performance status did not deteriorate throughout the period of the chemotherapy. These results suggest that hepatic arterial MTX/5-FU is safe and worth trying in patients with liver metastases from colorectal carcinoid.

[Results of resection of locally recurrent rectal cancer].

AIMS OF THE STUDY: The treatment of locally recurrent rectal cancer (LRRC) remains a difficult and controversial issue. The aim of this study was to retrospectively assess the results of an univocal attitude associating resection of a priori resectable lesions using visceral excisions as required, without sacral excision, but including intra-operative radiotherapy (IORT). PATIENTS AND METHODS: Between 1989 and 1999, 32 patients underwent resection for LRRC. Twelve had previously undergone abdomino-perineal excision and 22 had received radiotherapy. Twenty-three patients underwent pelvic exenteration (total in 17, with rectus myocutaneous flap in 18). Twenty-five patients underwent IORT. RESULTS: Three patients (9.3%) died in the early postoperative period and 11 experienced complications (37%). Resections were considered R0 in 6 patients, R1 in 21 patients and R2 in 5 patients. Five-year survival rates, overall and without disability, were respectively 12%, 12% and 5%. Median survivals, overall and without disability, were respectively 22 and 12 months. CONCLUSION: Resection of LRRC remains a surgical challenge. It may achieve an average of one-year survival without disability, and hope for a few cures. Improvement of oncologic results might come from a more accurate patient selection.

Predictors for long-term survival after interdisciplinary salvage surgery for advanced or recurrent gynecologic cancers.

BACKGROUND AND OBJECTIVES: We wanted to identify factors which allow predicting long-term survival after pelvic exenteration (PE) for locally advanced or recurrent gynecologic malignancies. METHODS: All patients undergoing PE at our institution from 1983 to 2002 were screened. In 203 cases data were obtainable and analyzed with respect to factors predicting outcome considering morbidity, mortality, and survival. Follow-up data and data concerning late complications not documented in our records were obtained by telephone interviews. RESULTS: Mean age was 55 (22-77) years. PE was performed for locally advanced (36%) or recurrent (64%) cervical (n = 133), endometrial (n = 26), vaginal (n = 23), vulvar (n = 10), and ovarian cancer (n = 11, cases with rectum and/or bladder resections). In 13.4% (n = 26) the intent of the procedure was palliation in the remaining cure. Procedures performed were anterior (n = 91), posterior (45), or total (n = 67) PE. 53% of patients underwent preoperative radio-chemotherapy, 11.8% as a neoadjuvant treatment. Mean OR time was 8.1 hr, an average of 5.6 units of packed red blood cells were perioperatively transfused. Microscopically complete resection was achievable in n = 69 patients. Perioperative mortality was 1% (n = 2). Seventy-one percent (n = 144) of patients were available for follow-up. Five-year overall survival in patients treated with a curative intent was 21%, 5-year survival in those patients with complete resection was 32%. Forty-two percent of patients with a complete resection without lymph node involvement, age 30-50, curative intention, and the absence of a pelvic sidewall infiltration survived 5 years or longer. CONCLUSION: In our series a 5-year survival rate of over 40% could be achieved for nodal-negative patients without pelvic sidewall infiltration when treated with curative intent and after complete resection.

Clinical impact of FDG-PET imaging in post-therapy surveillance of uterine cervical cancer: from diagnosis to prognosis.

OBJECTIVES: To evaluate the ability of whole-body 2-[(18)F]-fluoro-2-deoxy-d-glucose (FDG) positron emission tomography (PET) scan to detect recurrent cervical cancer in women during follow-up after definitive treatment. METHODS: We retrospectively reviewed the whole-body FDG-PET scan of the women who had reached complete response after primary treatment for detection of recurrent cervical cancer between September 1, 2001 and October 31, 2004. RESULTS: One hundred twenty-one consecutive patients were registered for the current study and seventy-six women were diagnosed as recurrence, twenty of which were asymptomatic. The FDG-PET scan detected 73 (96.1%) patients among 76 patients with recurrent disease and discriminated 38 (84.4%) patients among 45 patients without recurrence. The sensitivity, specificity and accuracy of the FDG-PET scan in assessment of recurrence among patients with cervical cancer were 96.1%, 84.4% and 91.7% respectively. Sixteen patients with no evidence of distant metastasis on FDG-PET scan received pelvic exenteration; complete response was achieved in 6 (37.5%) patients, and all are alive with no evidence of disease. The FDG-PET scan detected FDG-avid lesions in 17 (85.0%) of the 20 asymptomatic patients with recurrent disease, and 8 (40.0%) patients received therapy with curative intent; complete response was achieved in five (25.0%) patients and all are alive with no evidence of disease. Three-year overall survival of this study was 85.6%. CONCLUSIONS: The whole-body FDG-PET scan is a sensitive post-therapy surveillance modality for detection of recurrent cervical cancer even in asymptomatic patients and aids in deciding treatment plans and, eventually, may have favorable impact on prognosis and survival.

Reconstruction with myocutaneous flaps following resection of locally recurrent rectal cancer.

Local or regional recurrence is frequent in patients treated for rectal cancer. Many will die with regional disease in the absence of distant metastases. To achieve cure or palliation, radical surgery resulting in large pelvic defects may be warranted. Myocutaneous flap reconstruction may be used to achieve satisfactory closure. From 1988 to 1993, nine patients (5 female, 4 male) underwent 10 myocutaneous flap reconstructions for large perineal or pelvic defects following surgical extirpation of recurrent rectal cancer at Fox Chase Cancer Center. All nine patients had been previously treated with radiation therapy. Their clinical course was reviewed and quality of life assessed. The mean age at diagnosis of recurrence was 56 years. In six, this was a first, and in three patients a second recurrence. Clinical presentation was most often bleeding, abscess, or perineal pain. Resection was determined by extent of recurrence and included perineal resection, pelvic exenteration, cystectomy, sacrectomy, or coccygectomy. Extent of disease necessitated intraoperative radiation therapy in one case and placement of brachytherapy catheters in four. Bilateral gracilis flaps were used in four, unilateral in three, gluteus maximus in two, and combined gluteal and gracilis flaps in one patient. Six perineal and four combined perineal and vaginal defects were reconstructed. The mean length of surgery was 9.1 hours, and the length of hospitalization averaged 17.5 days. In nine of 10 cases, patients had prehospital level of function at discharge. Acute surgical flap-related complications included three cases of minor wound infection or separation, two of minimal but persistent drainage, and one of vaginal colonization.(ABSTRACT TRUNCATED AT 250 WORDS)

Immediate reconstruction of the perineal wound with gracilis muscle flaps following abdominoperineal resection and intraoperative radiation therapy for recurrent carcinoma of the rectum.

BACKGROUND: Morbidity associated with a nonhealing perineal wound is the most common complication following proctectomy, particularly in the setting of recurrent carcinoma of the rectum and radiation therapy. Immediate reconstruction using the gracilis myocutaneous and muscle flaps significantly reduces the incidence of major infection associated with perineal wound closure. The purpose of this study was to assess the value of immediate reconstruction of the perineal wound using a gracilis flap in patients undergoing abdominoperineal resection and intraoperative radiation therapy. METHODS: This study retrospectively reviewed our experience with immediate pelvic reconstruction using gracilis muscle flaps for patients undergoing rectal extirpation and irradiation for recurrent carcinoma of the rectum. From 1990 to 1995, 16 patients underwent abdominoperineal resection (APR) or pelvic exenteration accompanied by immediate wound closure with unilateral or bilateral gracilis muscle flaps. Morbidity and mortality outcomes were compared to those of 24 patients from our institution who, between 1988 and 1992, underwent proctectomy and irradiation for recurrent rectal carcinoma with primary closure of the perineal wound. RESULTS: Major complications (i.e., major infection requiring hospitalization and/or operation) occurred in 2 (12%) of the patients with gracilis flaps versus 11 (46%) of the patients with primary closure (P = .028 by chi2 analysis for flap vs. primary closure). Minor complications (i.e., persistent sinus and subcutaneous abscess) occurred in 4 (25%) of the patients with gracilis flaps versus 5 (21%) of those with primary closure. CONCLUSION: Immediate perineal reconstruction using the gracilis myocutaneous flap following proctectomy and irradiation for recurrent rectal carcinoma significantly reduces the incidence of major infection associated with perineal wound closure.

[From urostoma to bladder replacement: current possibilities in urinary diversion].

OBJECTIVE: To analyse 48 urinary diversions in an oncological patient population. DESIGN: Retrospective study. SETTING: The Dutch cancer institute 'Nederlands Kanker Instituut/Antoni van Leeuwenhoek Ziekenhuis' in Amsterdam, the Netherlands. METHOD: The medical records of all patients who had a urinary diversion in the period 1989-1993 were analysed for type of diversion, indication for this specific type and postoperative complications. RESULTS: In 48 patients (24 women and 24 men with a mean age of 62.1 years) a urinary diversion was constructed because of cystectomy for bladder cancer (n = 27), cystectomy in total pelvic exenteration (13), total urinary incontinence following radiotherapy (5), urethral cancer (1) or local palliation (2). Twenty-one diversions according to Bricker, 25 continent reservoirs according to Rowland and (or) neo-bladders, I ureterosigmoidostomy and I continent access to the bladder (Mitrofanoff procedure) were done. The standard diversion according to Bricker was preferred in the following circumstances: extensive intestinal resections (also previous ones), older age, fear of incontinence or no need for continent diversion. Specific problems of the new diversion techniques were difficulties of patients with catheterising the reservoir and folic acid deficiency. All other postoperative problems were related to the extensiveness of the primary oncological procedure rather than to the diversion technique. CONCLUSION: Apart from a few contraindications such as shortage of intestine, tumour growth into the urethra and patients' inability or unwillingness to catheterize themselves, there are no objections to the new diversion techniques (continent reservoir/neo-bladder). Patients being considered for urinary diversion ought to be informed about these new techniques.
