[Granulosa cell tumor: implantation metastasis to the abdominal wall].

We report on the rare localization of a metastasis in the abdominal wall of an ovarian Granulosa Cell Tumor, manifested as a haematoma in the abdominal wall nine years after the primary operation of the Granulosa Cell Tumor. The therapy consisted of a wide excision of the tumor, hysterectomy with a partial excision of the remaining ovary and resection of the omentum majus. Our case report illustrates the clinical problems of these kind of tumors.

Abdominal wall endometriomas.

OBJECTIVE: To investigate the clinical characteristics, treatment, and factors of recurrence of abdominal wall endometriomas (AWE). METHOD: Sixty-four cases of AWE diagnosed at Peking Union Medical College Hospital (PUMCH) from 1983 to 2003 were reviewed retrospectively. RESULT: There was an AWE incidence of 0.044% among the parturients undergoing cesarean section at PUMCH, of whom 87.5% had the typical complaint of an enlarging mass and pain during menstruation. Among these women, 62 underwent low abdominal surgery for endometrioma (2 for primary umbilicus endometrioma); 2 women with small endometriomas opted for a temporary medical solution and had relief after menopause. The latent period of AWE positively correlated to the women's age at onset of symptoms (P<0.001). Of the 62 women who underwent local excision, 19 had an unsatisfactory experience with medical management. There were 5 recurrences and 1 evolution to malignancy during a mean follow-up of 83.7 months. Recurrence was closely related to the size and depth of lesions. CONCLUSION: Because of its typical clinical manifestations, abdominal wall endometriomas could be diagnosed before pregnancy. Surgical excision is the only effective treatment and wide local excision with clear margins is the key point to prevent recurrence.

Quantitative evaluation of abdominal wall perfusion after different types of laparotomy closure using laser-fluorescence videography.

Laparotomy closure relies on the incisional edges as anchor for the suture material. The results of these techniques are not satisfying, with failure rates of up to 20%. To investigate the effect of different conventional closure techniques and a novel "bridging technique" on abdominal wall perfusion an animal study was performed in rabbits. Abdominal wall perfusion was measured using the method of dynamic laser-fluorescence videography in the first 72 h of incisional wound healing in 25 animals. Suture tension was controlled with a water-filled polyurethane balloon connected to a pressure detector. The effect of laparotomy closure on abdominal wall tissue perfusion depends significantly on the applied technique and suture tension. Avoiding direct sutures in the incisional edges during laparotomy closure leads to a better tissue perfusion of the incisional region than conventional suture techniques. Suture tension can be controlled and adjusted using a water-filled polyurethane balloon as a pressure sensor.

Improved surgical mesh integration into the rat abdominal wall with arginine administration.

Prosthetic meshes are used as the standard of care in abdominal wall hernia repair. However, hernia recurrences and side effects remain unsolved problems. The demand by health care providers for increasingly efficient and cost-effective surgery encourages the development of newer strategies to improve devices and outcomes. Here, we evaluated whether l-arginine administration was able to ameliorate long-term polypropylene prostheses incorporation into the abdominal wall of Sprague-Dawley rats. Meshes were placed on-lay and continuous l-arginine was administered. In vivo biocompatibility was studied at 7, 25 and 30 days post-implantation. Effectively, l-arginine administration in combination with mesh triggered subtle changes in ECM composition that impinged on critical biochemical and structural features. Lastly, tensile strength augmented and stiffness decreased over the control condition. This could help to restructure the mechanical load transfer from the implant to the brittle surrounding tissues, i.e., impact load and fatigue load associated with mechanical tensions could be distributed between the mesh and the restored tissue in a more balanced manner, and ultimately help to reduce the incidence of loosening, recurrences, and local wound complications. Since the newly formed tissue is more mechanically stable, this approach could eventually be introduced to human hernia repair.

Fresh autologous transplantation of ovarian cortical strips to the anterior abdominal wall at the pfannenstiel incision site.

OBJECTIVE: To describe an open surgical technique for transplanting fresh ovarion tissue to the anterior abdominal wall at the incision site and to determine whether ovarian function would be restored after transplantation. DESIGN: Case study. SETTING: Academic medical center. PATIENT(S): A 44-year-old patient who underwent an operation for uterine fibroids. INTERVENTION(S): Microsurgical reconstruction of ovarian cortex and its transplantation to the anterior abdominal wall at incision site of Pfannenstiel. MAIN OUTCOME MEASURE(S): Follicular development evident by ultrasound examination; restoration of serum FSH and LH levels to nonmenopausal range; and disappearance of menopausal symptoms. RESULT(S): Early postoperative FSH, LH, and E(2) levels showed that menopause was confirmed. Postoperative hormone levels at months 2, 3, and 6 were as follows: FSH: 77.86, 79.50, and 13.70 mIU/mL; LH: 34.60, 33.92, and 8.78 mIU/mL; E(2): 29, 46, and 48 pg/mL. The patient is still followed-up for postmenopausal status. CONCLUSION(S): Autotransplantation of cortical strips to the anterior abdominal wall at the incision site without further incision can be a logical solution for the patients at early climacteric age.

Brachytherapy technique for abdominal wall metastases of colorectal cancer: ultrasound-guided insertion of applicator needle and a skin preservation method.

PURPOSE: To report a technique of interstitial brachytherapy for the treatment of subcutaneous metastatic abdominal wall tumors. MATERIAL AND METHODS: We developed a brachytherapy technique consisting of ultrasound-guided insertion of applicator needles to avoid the organs at risk, such as intestines, and saline injection into the subcutaneous tissue between the tumor and the skin to decrease the skin dose. We encountered three patients with painful metastases from rectal carcinoma in the abdominal wall refractory to external radiotherapy. They were subjected to this brachytherapy with a single dose of 20 Gy. RESULTS: The procedure was safely achieved in all three patients. Long-lasting pain reduction and tumor shrinkage was obtained without early or late complications. CONCLUSION: This interstitial brachytherapy technique seems to be feasible in the treatment of metastatic abdominal wall tumors.

Congenital anterior abdominal wall defects in England and Wales 1987-93: retrospective analysis of OPCS data.

OBJECTIVES: Analysis of incidence and characteristics of congenital abdominal wall defects, with special reference to the differences between the incidence of gastroschisis and exomphalos (omphalocele). DESIGN: Retrospective analysis using data from the Office of Population Censuses and Surveys (recoded to differentiate exomphalos and gastroschisis) and the National Congenital Malformation Notification Scheme. SETTING: England and Wales, 1987 to 1993. RESULTS: 1043 congenital anterior abdominal wall defects were notified within the seven year study period. Of these, 539 were classified as gastroschisis, 448 as exomphalos, 19 as "prune belly syndrome," and 37 as "unclassified." Gastroschisis doubled in incidence from 0.65 in 1987 to 1.35 per 10,000 total births in 1991, with little further change; the incidence of exomphalos decreased from 1.13 to 0.77 per 10000 births. The overall incidence of notified congenital abdominal wall defects was 2.15 per 10000 total births. Gastroschisis was associated with a lower overall maternal age than exomphalos and with a significantly lower proportion of additional reported congenital malformations (5.0%) than in the cohort with exomphalos (27.4%) (odds ratio 0.14, 95% confidence interval 0.09 to 0.22; P < 0.001). The sex ratio of the two cohorts was the same. The incidence of gastroschisis and exomphalos was higher in the northern regions of England than in the south east of the country. CONCLUSIONS: The national congenital malformation notification system showed an increasing trend in the incidence of fetuses born with gastroschisis and a progressive decreasing incidence of exomphalos in England and Wales between 1987 and 1993. Although the reasons for this are likely to be multifactorial, a true differential change seems likely. The observed increase in incidence of gastroschisis relative to exomphalos and the differentiation in maternal age have implications for resource management within the NHS and warrant further epidemiological monitoring. Regional differences may be due to a dietary or environmental factor, which requires further study.

Abdominal wall hernia complicating continuous ambulatory peritoneal dialysis.

Continuous ambulatory peritoneal dialysis (CAPD) is a well-established treatment modality for end-stage renal disease. Abdominal wall hernia is not uncommon in patients on CAPD. Two factors are responsible for the occurrence of these hernias: anatomically weak sites and increased intraperitoneal pressure by the dialysate. Abdominal wall hernia was reviewed in 44 patients on CAPD from 1987 through 1991. Eight abdominal hernias (5 inguinal, 2 incisional and 1 umbilical) were found during CAPD treatment (18.18%). Surgical treatment was applied in 6 symptomatic hernias (5 inguinal and 1 incisional). After surgery, 5 patients returned to CAPD without recurrence and the remaining one died of strangulated incisional hernia. Our series shows that: (1) a detailed examination of the preexisting hernia and repair prior to CAPD treatment are suggested. (2) symptomatic abdominal wall hernia should be evaluated carefully and treated promptly. (3) awareness of the complication of these hernias can reduce the morbidity and mortality.

Fine-needle aspiration cytology of abdominal wall scar lesions for diagnosing recurrent colorectal cancer.

Nodules in the abdominal wall scar after resection of colorectal cancer may represent nonmalignant or malignant lesions. We report clinical and fine-needle aspiration (FNA) cytologic findings in five patients with nodules suspected of being malignant. All patients had had adenocarcinoma, four of the colon and one of the rectum. Postoperative abdominal wall irradiation had been administered to three patients. The median time from surgical removal of the cancer to FNA of scar nodules was 27 months. Three patients had malignant and two patients had nonmalignant FNA cytology, histologically confirmed at surgical biopsy of scar nodules. The malignant histologic cell type demonstrated by FNA cytology of the scar lesions was identical to that exhibited by histology. The survival of patients with positive cytology and histology ranged between 9 and 43 months; survival of patients with negative cytology and histology was between 53 and 138 months. We conclude that FNA cytology is a simple, sensitive, and specific procedure to evaluate patients with scar nodules appearing after resection of colorectal cancer. This procedure may safely replace surgical biopsy in the initial evaluation of scar nodules.

Congenital cranioventral abdominal wall, caudal sternal, diaphragmatic, pericardial, and intracardiac defects in cocker spaniel littermates.

Five littermate Cocker Spaniels were born with concomitant pericardial, diaphragmatic, caudal sternal, and cranioventral abdominal wall defects. Three of the 5 pups had ventricular septal defects. A sixth pup with a cranioventral abdominal wall defect died 4 days after birth. No history of teratogen exposure was reported, and none of the pups from previous litters of the dam was affected. Each pup underwent successful surgical correction (without median sternotomy) of the diaphragmatic and cranial abdominal wall defects when they were 10 to 12 weeks old. The ventricular septal defects were not corrected. In 2 of 3 pups with ventricular septal defects, thoracic radiography 6 months after surgery revealed moderate generalized cardiomegaly. All pups were healthy one year after surgery.

Abdominal wall lift. Low-pressure pneumoperitoneum laparoscopic surgery.

A method of abdominal wall lift has been developed and evaluated clinically in this unit during the past 18 months. It permits the conduct of laparoscopic procedures at an intraabdominal pressure of 6-8 mm Hg. The technique was introduced for laparoscopic surgery in patients with preexisting cardiac disease and chronic bronchitis. The procedure, by lifting both the abdominal wall and the falciform ligament together, also elevates the central portion of the liver (segments 3-5), thereby improving the surgical exposure. For this reason it is now also used in fit patients with ptotic livers or hypertrophied quadrate lobes undergoing laparoscopic cholecystectomy and common bile duct exploration, and to facilitate left subhepatic exposure in patients during laparoscopic antireflux surgery and vagotomy.
