Carcinoma of the neovagina: case report and review of the literature.

BACKGROUND: Carcinoma of the vagina is a rare disease, and it is even more rare in the neovagina. Nevertheless, it has been well described. The aim of this report was to analyze the reported cases and to add observations concerning a risk profile for this rare occurrence of carcinoma. CASE REPORT: The 29-year-old patient's history included congenital absence of vagina as a result of Rokitansky-Kuster syndrome. In 1987, when the patient was 17 years old, a neovagina was constructed by dissection between the bladder and the rectum, according to the Warthon method, and the apex of the neovagina was covered with Dura-mater. In 1990 the patient underwent radiation treatment with brachytherapy three times in combination with surgical treatment, because of granulation tissue in the neovagina. In 1999 several specimens of the granulation tissue were removed and histological examination showed intermediate differentiated squamous cell carcinoma. Total exenteration with pelvic and lower paraaortic lymph node dissection was performed, and the patient received a continent neobladder (Mainz Pouch I), colostoma, and sigma neovagina. Two months later in January 2000 the patient showed local recurrence and after local excision the patient received radiotherapy. The follow-up to June 2001 showed no evidence of disease. CONCLUSION: All patients with vaginoplasty should undergo regular 1-year follow-ups, including smear analysis because of the possibility of the development of carcinoma. Granulation tissue arising in a neovagina should be biopsied and no prosthesis should be used until lesions have healed completely. Patients who have undergone radiation of the neovagina carry an additional risk.

Jejunal pouch interposition after pylorus-preserving gastrectomy.

BACKGROUND: To improve the quality of life of patients undergoing gastrectomy, a nerve-conserving jejunal pouch was interposed after pylorus-preserving gastrectomy (PPG) with vagal nerve preservation. We report the details of the operative technique and the outcome. METHODS: PPG with lymph node dissection was performed, preserving the hepatic, pyloric, and celiac branches of vagal nerve. The jejunum was cut approximately 20 cm distal to the ligament of Treitz. Marginal vessels were not divided in order to preserve the nerves in the jejunum that were used to construct the pouch. A linear stapler was used to perform a side-to-side jejunojejunostomy. A 12-cm-long pouch was formed by firing the stapler twice. The pouch was interposed between the residual parts of the stomach. Postoperatively, the patients were interviewed periodically. A dual-phase, dual-isotope radionucleid pouch-emptying study was performed 6 months after surgery. RESULTS: A total of 13 patients underwent the operation. No complication developed. During the first 6 months after surgery, the body weight of the patients was maintained at 91% of the preoperative level. The radioisotope retention rate for the combined pouch and residual stomach was 46% for liquid food and 76% for solid food 120 min after ingestion. The pattern of its emptying was similar to that in healthy individuals. CONCLUSIONS: The pouch-emptying test demonstrated a satisfactory retention capacity and acceptable emptying for the gastric substitute. A reasonably good quality of life has been obtained for patients undergoing PPG with interposition of a nerve-preserving jejunal pouch.

Fundus rotation gastroplasty: a modified gastric tube.

Anastomotic failure remains to be one of the main problems in esophageal surgery with leakage rates up to 30% being reported currently. We addressed that problem by modifying the gastric-tube formation in utilizing all of the gastric fundus and omitting the resection of the lesser gastric curvature and accompanying vessels. Experimentally, those fundus-rotation gastroplasties were significantly longer and better perfused than conventional gastroplasties. In a clinical series of 53 patients (45 male, eight female, range 42-83 years) undergoing esophageal resection (49 malignancies, four non-malignant esophageal disease), four anastomotic leakages were found (7.5%). Three patients died due to a bronchial leak and adult respiratory distress syndrome, one with a complete gastric-tube necrosis and one with a colon perforation, sepsis and multiorgan failure. Eight patients developed a significant anastomotic stricture requiring repeated endoscopic dilatations. From our experimental and clinical experience, we conclude that the favorable length and perfusion of fundus-rotation gastroplasties allow for safe anastomosis at either the cervical or thoracic level.

Pseudoneotesticle formation using indigenous scrotal structures.

We report on our experience with a new surgical procedure of forming a pseudoneotesticle from indigenous tissues obtained from the existing scrotal contents. This procedure has been performed in 32 patients with a diagnosis of hormone dependent cancer of the prostate as a therapeutic manoeuvre, and in 3 children who had diminution of their testicle down to a peanut size secondary to neglected testicular torsion on the ipsilateral side. The follow-up examination revealed a small decrease in the size of the pseudotesticles that remained stable in further evaluation. This new surgical technique is proposed as a viable alternative to the placement of various artificial scrotal prostheses.

Quality of micturition in male patients with orthotopic neobladder replacement.

We evaluated the quality of micturition in patients with orthotopic neobladder replacement. In the present study, 58 patients who had undergone orthotopic neobladder replacement following cystectomy were enrolled. The quality of micturition was evaluated by means of uroflowmetry, a self-administered questionnaire and a 24-h frequency-volume chart. The questionnaire consisted of 26 questions concerning storage (9 questions), evacuation of urine (9), patient's satisfaction with neobladder (3), limitations in daily life (3) and pain (2). In addition, 11 of the questions were followed immediately by a question concerning inconvenience to the patients. The mean follow-up period was 35 months (range 6-80). On uroflowmetry, the mean peak flow rate was 13.5 ml/s with a low average flow rate (mean: 5.7 ml/s), and the voiding time was considerably prolonged (mean: 70.2 s). According to the frequency-volume chart and questionnaire responses, although the frequency and tidal volume of micturition were normal, the majority of patients were conscious of retarded, intermittent, prolonged, and weak stream and of straining during voiding. Diurnal or nocturnal incontinence was noticed subjectively in as many as 69% of the patients. However, the degree of urine leakage was minimal. In spite of the fact that 66% of the patients replied that their micturition status was worse than before surgery and that 69% of the patients felt dissatisfied, the degree of inconvenience was low in every item and the limitations in daily life were minimal. Although micturition in patients with neobladder replacement appeared to be of lower quality than that in normal subjects and was considered by many to be unsatisfactory, most patients were able to adjust themselves to it without significant inconvenience.

Laparoscopic-assisted formation of a colon neovagina.

We report the laparoscopic formation of a colon neovagina following radical hysterectomy with subtotal colpectomy and radiotherapy in a 43-year-old woman who wished to resume normal vaginal sexual intercourse. The rectum was transected by a laparoscopic stapling device, preserving the inferior mesenteric and the superior rectal artery. By suprapubic mini-laparotomy, the rectosigmoid colon was eventerated and transected 8 cm above the staple line. Following colorectal anastomosis, the isolated bowel segment was rotated 180 degrees and placed on the right side of the anastomosis. A 12-mm trocar was introduced, transvaginally, and the isolated bowel segment was sutured to the vaginal resection margin. There were no peri- or postoperative complications. Six months after surgery, a stenotic area at the entrance to the neovagina was incised. At 12 months after primary surgery, the neovagina allowed normal sexual activity. Laparoscopically assisted formation of a colon neovagina is a surgical alternative for vaginal reconstruction that can be performed successfully even in irradiated patients.

Laparoscopically assisted abdominoperineal resection and simultaneous total anorectal reconstruction with electrostimulated static-dynamic graciloplasty.

Bilateral electrostimulated graciloplasty, performed in a "static-dynamic" configuration around a perineal colostomy (total anorectal reconstruction-TAR), has been proven a reliable way to restore continence in patients who undergo to abdomino perineal resection (A.Pe.R.) of the anorectum for lower rectal cancer. In selected cases, laparoscopically assisted TAR can significantly improve body-image preservation and aesthetic results. A 33-year-old woman affected by lower rectal cancer was submitted to laparoscopic-assisted A.Pe.R and TAR with simultaneous bilateral graciloplasty; a suprapubic median mini-access was adopted to fully mobilize the mesorectum in absence of pneumoperitoneum. A subcutaneous pulse generator and special electrodes were also implanted to chronically electrostimulate the graciloplasty. In spite of postoperative bleeding which required a blood transfusion, postoperative outcome was satisfactory; electrostimulation was started on the 10th postoperative (p.o.) day and the patient was discharged on the 17th p.o. day. Two months after TAR, level II continence (N.S. Williams Scale) was achieved. In selected cases, laparoscopically assisted A.Pe.R. and TAR can be safely adopted to preserve body image and quality of life, avoiding at the same time a large abdominal approach and a "permanent" abdominal colostomy.

Autogenous valve reconstruction technique for post-thrombotic reflux.

Post-thrombotic reflux in deep veins of the lower extremities cannot be treated by in situ valvuloplasty because of valve degeneration. The outcome of transplantation and transposition of segments with valves is controversial. From feasibility tests in animals and fresh human cadavers we have developed an autogenous valve reconstruction technique. The valve is fashioned from the proximal end of the greater saphenous vein that is left attached to the femoral vein, invaginated, and fixed to the venous wall. This technique provides a competent bicuspid valve. In a series of 19 patients operated on in 1995 we performed 20 valve reconstruction procedures at the level of the femorosaphenous junction by invagination of a fragment from the proximal end of the greater saphenous vein in the common femoral vein. Mean follow-up time was 10 months. No complications were observed. All femoral veins were patent and competent except one in which mild reflux was observed because of insufficient valve size. Further follow-up is needed to confirm the efficacy of this simple, new technique.

Additional microvascular anastomosis in reconstruction after total esophagectomy for cervical esophageal carcinoma.

BACKGROUND: Maintaining sufficient blood flow to the substitute organ after total esophagectomy is essential for decreasing the risk of anastomotic leakage. Additional venous, or arterial and venous, anastomoses between the vessels of the gastric tube and the vessels in the neck after total esophagectomy are described for 11 patients with cervical esophageal carcinoma. METHODS: The tissue blood flow was measured by laser Doppler flowmetry before and after anastomosis. Venous anastomosis was performed for all 11 patients, and arterial anastomosis was added for 7 patients. RESULTS: A significant increase in tissue blood flow was observed after venous anastomosis alone (mean, 19%; P < 0.05) and after arterial and venous anastomoses (mean 43%; P < 0.01). There was no anastomotic leakage or hospital death. CONCLUSIONS: This procedure may reduce the risk of anastomotic leakage especially in the case of pharyngogastrostomy following total esophagectomy.

Laparoscopic creation of a neovagina in patients with Rokitansky syndrome: analysis of 52 cases.

OBJECTIVE: To evaluate the surgical feasibility and the long-term anatomic and functional results of a new procedure that uses the endoscopic approach to treat uterovaginal agenesis, known as Rokintansky syndrome. DESIGN: Evaluation of surgical feasibility and recording of clinical data over a 12-month follow-up. SETTING: Tertiary referral center for the treatment of female genital malformations. PATIENT(S): Fifty-two patients with vaginal agenesis. INTERVENTION(S): The laparoscopic version of the Vecchietti method was used to create a neovagina. MAIN OUTCOME MEASURE(S): Anatomic success was defined as a neovagina >/=6 cm long, allowing easy introduction of two fingers, within 6 months after corrective surgery. Functional success was considered achieved if the patient reported satisfactory sexual intercourse starting from 6 months after surgery. RESULT(S): The surgical procedure was performed with no major complications and with 100% anatomic success; functional success was obtained in 98.1% of the study population. CONCLUSION(S): In patients with Rokitansky syndrome, the laparoscopic approach for creating a neovagina by the Vecchietti method is simple, safe, and effective.

Creation of a neovagina following Williams vaginoplasty and the Creatsas modification in 111 patients with Mayer-Rokitansky-Küster-Hauser syndrome.

OBJECTIVE: Evaluation of the Creatsas modification of Williams vaginoplasty for the creation of neovagina in patients with Mayer-Rokitansky-Küster-Hauser syndrome (MRKH syndrome). DESIGN: Record of perioperative and postoperative results and complications. Follow-up evaluations of patients yearly after the operation. SETTING: Division of Pediatric-Adolescent Gynecology and Gynecologic Corrective Surgery, University of Athens (tertiary referral center). PATIENT(S): One hundred eleven patients with MRKH syndrome. INTERVENTION(S): Surgical creation of neovagina using the Williams vaginoplasty technique (group A: 10 patients) or the Creatsas modification of the previous method (group B: 101 patients). MAIN OUTCOME MEASURE(S): Length and width of the neovagina, and the quality of sexual life postoperatively. RESULT(S): A functioning vagina of 10 to 12 cm depth and 5 cm width was created in eight of the patients in group A (80%) and in 98 of those in group B (97.02%). A vagina of 7 to 9 cm depth and 2 to 3 cm width was created in the rest of the patients in both groups. In group A, two wound openings were reported (20%); in two of the patients hemorrhage occurred during the first intercourse, compared to none in group B. A satisfactory sexual life was reported from 94.4% of the patients and an adequate one from 4.16% of them. CONCLUSION(S): The Creatsas modification of Williams vaginoplasty is a simple and effective technique for the creation of a functioning neovagina in young women with vaginal aplasia.

Laparoscopy-assisted Ruge procedure for the creation of a neovagina in a patient with Mayer-Rokitansky-Küster-Hauser syndrome.

OBJECTIVE: To describe the successful use of a laparoscopy-assisted Ruge procedure for the reconstruction of a vagina in a patient with Mayer-Rokitansky-Küster-Hauser syndrome. DESIGN: Case report. SETTING: A university hospital. PATIENT(S): A 19-year-old Japanese woman with Mayer-Rokitansky-Küster-Hauser syndrome. INTERVENTION(S): Creation of a neovagina by a laparoscopy-assisted Ruge technique. MAIN OUTCOME MEASURE(S): Clinical examinations were performed during the follow-up period. The depth and diameter of the neovagina were measured by vaginography. Patient satisfaction also was determined. RESULT(S): The neovagina was 12 cm in length and 4 cm in diameter. The mucosa of the neovagina was pinkish and had a moist surface. No intraoperative or postoperative complications were observed. CONCLUSION(S): The use of an isolated segment of the sigmoid colon for vaginal construction has the advantages of providing a sufficient length of neovagina and not requiring immediate postoperative self-dilatation. We believe that our procedure has various advantages in addition to those of the original Ruge method, including its minimally invasive nature and excellent cosmetic results. Further, a laparoscopy-assisted operation allows for the diagnosis of uterine defects and the creation of a neovagina at the same time.

The relationship between Helicobacter pylori infection and acid-hematuria syndrome in pediatric patients with gastric augmentation-II.

BACKGROUND/PURPOSE: The acid-hematuria syndrome, which presents with dysuria, hematuria, and perineal pain still remains a problem in those patients who have undergone bladder augmentation using the gastrocystoplasty technique. Additionally, there is still a question regarding the explanation for postoperative metabolic problems such as metabolic alkalosis, hypocholoremia, hypergastrinemia, and various complications related to gastritis and peptic ulcer disease. The aim of this study was to investigate the relation of Helicobacter pylori (HP) infection in this patient group and the relationship between HP infection and the above-mentioned clinical problems and complications. METHODS: In this study, 10 children with a history of previous gastrocystoplasty (five girls, five boys; mean age, 6.75+/-2.53 years; range, 2.5 to 12 years) were evaluated. Blood samples for HP detection were analyzed by serological testing (ELISA technique). Histopathologic studies were performed for gastric tissue specimens, obtained by endoscopic procedures from the stomach and augmented bladder. Urine pH and serum gastrin levels were measured in all patients. RESULTS: Regarding the serological studies, four of ten patients had a positive ELISA test result (40%). The four patients with HP-positive serological test results, were the patients who had acid-hematuria syndrome. These patients also had low urine pH levels (mean, 4.5) when compared with those of HP-negative patients. HP-positive patients also had high serum gastrin levels in comparison with those of HP-negative patients. CONCLUSIONS: The relation between HP infection and problems such as hypergastrinemia, acid output, and ulcer disease is well known. Our study demonstrates a correlation between the HP-positive gastrocystoplasty patients and the above-mentioned symptoms and complications. Because of the potential risk of HP infection, we suggest that HP infection be investigated in patients with gastrocystoplasty or in candidates for a gastrocystoplasty operation. HP-positive patients should be treated, to reduce the risks of postoperative complications.

Revascularization using the short gastric vessels of the gastric tube after subtotal esophagectomy for intrathoracic esophageal carcinoma.

BACKGROUND: Maintaining sufficient blood flow to the substitutive organ after esophagectomy is essential to decrease the risk of anastomotic leakage. STUDY DESIGN: Forty-one patients underwent subtotal esophagectomy for intrathoracic esophageal carcinoma and reconstruction using the gastric tube. Additional vascular anastomosis between the short gastric vessels and the vessels in the neck was performed in 15 patients. Tissue blood flow was measured by laser Doppler flowmetry before and after vascular anastomosis. The incidence of anastomotic leakage in the revascularization group was compared with that in the remaining 26 patients. RESULTS: Venous anastomosis was performed in 14 patients and arterial anastomosis in 9. There was a significant increase in tissue blood flow after venous anastomosis alone (mean percent increase: 36%; p < 0.01), and after arterial and venous anastomoses (mean percent increase: 108%; p < 0.01). No anastomotic leakage was observed in the revascularization group; six patients (23.1%) in the control group had leakage (p < 0.05). Patients in the revascularization group started taking a meal 10.0 +/- 0.4 days postoperatively, compared with 15.1 +/- 1.8 days in the control group (p < 0.05). CONCLUSIONS: Additional vascular anastomosis in esophageal reconstruction after subtotal esophagectomy achieved good results. This procedure can reduce the risk of anastomotic leakage and may be useful for esophageal reconstruction.

Clinical outcome and long-term survival rates after esophagectomy are not determined by age over 70 years.

Esophagectomy is considered a high-risk procedure in patients aged 70 years or older. This study evaluates the impact of two age groups (younger than 70 and 70 years or older) on clinical outcome and long-term survival rates following this procedure. This prospective study included survival analysis and clinical evaluations at 3, 6, and 12 months after esophagectomy. All esophagectomy patients undergoing gastric (n = 125), jejunal (n = 10), or colonic (n = 4) reconstructions at our institution from 1984 to 1996 were included. Fifty patients were older than 70 years, 89 were younger, and 120 of these 139 patients had tumors. The overall hospital mortality rate was 1.4% (2 of 139), both in the younger age group. All leaks from anastomoses and grafts were nonfatal, and these problems occurred in seven patients in the younger age group and two in the older group. The mean preoperative weight was 70 kg, and there was a mean weight loss of 5 kg during the first three postoperative months only but none thereafter (P <0.001). This was the same for patients with benign and malignant disorders, and for those aged over or under 70 years. Between 71% and 77% of the patients experienced no dysphagia at the three evaluations during the first postoperative year. The distribution of the different grades of dysphagia was equal in the two age groups at 3-month (P = 0.339) and 12-month (P = 0.669) follow-up. The 12-year survival rate was 28% and the 5-year rate was 31%, and this was correlated to tumor stage (P = 0.002) but not to age over or under 70 years (P = 0.299). The clinical outcome was the same regardless of whether patients were over or under 70 years of age. Tumor stage but not age over 70 years was the major predictive factor for long-term survival.
