Bipedicled skin flaps for reconstruction of the abdominal wall in newborn omphalocele.

Despite technical refinements in surgery and advances in postoperative intensive care, abdominal wall closure in giant omphalocele remains a difficult endeavor. In this respect, bipedicled skin flaps obtained with longitudinal incisions along the margins of the rectus abdominis muscle may represent a good alternative solution to achieve a complete, tension-free midline closure. Incisional areas can subsequently be easily covered with split-thickness thigh grafts. Two neonatal cases were treated with this technique with good results. This has enabled avoidance of palliative coverage as well as complex musculo-cutaneous reconstructions at a later age.

Endometriosis of the abdominal wall.

Endometriosis is ectopic endometrial tissue that responds to hormonal stimulation and is found 8-15 per cent of all menstruating women. Endometrioma in/or close to a surgical scar is rare and occurs in 0.1 per cent of women who underwent cesarean section. When localized at the abdominal wall, the disease presents as a painful swelling resembling other lesions, such as hernias, post-operative ventral hernias, hematomas, granulomas, abscesses, and tumors. Endometriosis of the abdominal wall may not be considered in the differential diagnosis of masses detected in/or close cesarean scar. Three cases are reported here. All of them underwent surgery and the error of the pre-operative diagnosis was revealed by histology in two cases. Actually, only one case was suspected pre-operatively.

Entero-colocutaneous fistula: a late consequence of polypropylene mesh abdominal wall repair: case report and review of the literature.

BACKGROUND: The underlying risk associated with visceral mesh erosion is the close opposition of adjacent intestines to the prosthetic graft. This highly morbid condition has been described with most types and techniques of abdominal wall mesh repair. PATIENT: We report the case of a 52-year-old man who presented with an entero-colocutaneous fistula 10 years after prosthetic mesh repair of an incisional hernia. The fistula was excised and the abdominal wall defect repaired with a tissue-impervious composite. CONCLUSIONS: The use of a tissue-impervious barrier avoids development of enteric fistula when a prosthesis is placed directly over the viscera.

Healing process induced by three composite prostheses in the repair of abdominal wall defects.

The present study compared the performance of three composite prostheses used to repair abdominal wall defects in rabbits. Two of them [Parietex Compositereg (PC) and Composixreg (CS)] are commonly used in clinical practice and one was designed by the present team (PL-PU99). At 14 and 90 days postimplant, specimens were obtained for morphological, macrophage response (RAM-11) and morphometric and biomechanical analysis. The prosthetic area covered by adhesions was significantly greater (p < 0.05) in the CS group (6.83 plus minus 2.31 cm(2)) than in PC (0.11 +/- 0.02 cm(2)) or PL-PU99 (0.10 +/- 0.07 cm(2)). At 14 days, it was observed a homogeneous, organized, well-vascularized neoperitoneum that was significantly thicker (p < 0.05) in PL-PU99. Except in the CS implants, this layer was covered by a continuous mesothelium. All three composites achieved good recipient tissue integration. Highest macrophage levels were recorded at 14 days with significantly higher values in the PL-PU99 prosthesis. Biomechanical strength was significantly greater (p < 0.05) in CS at two weeks postimplant, but it was similar at 90 days. These findings suggest that the three composites show ideal integration with host tissue, along with similar biomechanical strength at 90 days, and significantly higher adhesion formation is induced by the CS prosthesis, possibly due to incomplete mesothelialization of the lower prosthetic surface.

Anterior abdominal wall pathologies detected by high-frequency annular array.

AIM AND METHODS: In 1850 patients, high-frequency (HF: 7.5-10 MHz) annular array US examination was performed to evaluate the value of HF annular US in the detection of pathologies of the anterior abdominal wall. RESULTS: HF annular US revealed pathological lesions (metastasis, benign tumor, lymphoma, hematoma, fistula, hernia, abscess) in 37 patients. The lesions were detected by conventional medium-frequency (3.5-3.75 MHz) US in only 8 of 37 cases (21.6%). HF annular US added information that altered clinical management in 19 cases (51.4%), predominantly in cases with tumors and fistulas. CONCLUSION: The addition of HF annular US to a conventional US examination increases the detectability of small, but clinically important pathologies in the anterior abdominal wall.

Pneumoperitoneum impairs blood flow and augments tumor growth in the abdominal wall.

BACKGROUND: Despite several clinical and experimental studies, the mechanisms behind the development of port site metastases in laparoscopic surgery have remained largely unknown. The current study was designed to investigate the effect of pneumoperitoneum on blood flow in the abdominal wall and its possible effects on tumor growth at this site. METHODS: A total of 40 Wistar Fu rats had a laser Doppler probe placed on their left rectus muscle and a suspension of 50,000 adenocarcinoma cells was injected into their right rectus muscle. The experimental group (n = 20) was insufflated with air at 10 mmHg for 45 min while abdominal blood flow was registered before and during insufflation and after exsufflation. The control group (n = 20) was not insufflated but the blood flow was recorded in the same manner. After 9 days, all animals were killed and the occurrence of tumor was observed. The tumors were analyzed with respect to weight and volume. RESULTS: The insufflation caused an 82% reduction in blood flow in the experimental group (p < 0.001). No reduction in blood flow was registered in the control group. Tumor nodules developed significantly more often in the insufflated group (20/20) compared to the controls (14/20) (p = 0.016). Tumor weight (p = 0.003) and volume (p < 0.001) were significantly increased in the insufflated group. CONCLUSIONS: Pneumoperitoneum seems to enhance tumor growth. It also causes a significant reduction in blood flow in the abdominal wall, which may contribute to the increased susceptibility of tumor take.

Abdominal wall massage: effect on colonic function in healthy volunteers and in patients with chronic constipation.

Colonic massage has been claimed to be an efficacious treatment for chronic constipation, though there are no studies to prove this. We therefore investigated the effect of abdominal wall massage on stool frequency and colonic transit time of radiopaque markers in 9 constipated patients (68 +/- 5 years, 5 female, colonic transit greater than 60 h) and in 7 healthy male volunteers (27 +/- 1.2 years) in a control phase and during a three week treatment phase with 9 sessions. Massage was performed as propulsive abdominal wall massage along the presumed course of the colon in an aboral direction (each session 20 min). Stool frequency did not change significantly from control to massage, neither in patients [0.59 +/- 0.08 to 0.68 +/- 0.09 defaecations per day, 95% CI control-massage (-0.23; 0.04)] nor in healthy volunteers 1.11 +/- 0.11 to 0.86 +/- 0.13, 95% CI (-0.01; 0.53)]. Total colonic transit times remained similar during the control and massage phase in patients (126 +/- 19 and 111 +/- 17 h, 95% CI (-11; 41)] and in healthy volunteers (40 +/- 7 and 38 +/- 6 h, 95% CI (-8; 13)]. Even when patients and healthy volunteers were statistically evaluated together, control and massage did not differ significantly. In patients, scores of well-being and stool consistency did not differ significantly during control and massage periods. So colonic massage does not change parameters of colonic function to a clinically relevant degree in healthy volunteers and constipated patients of the investigated age-groups.

Management of abdominal wall defects resulting from complications of surgical procedures.

This article presents the author's personal philosophy for treatment of various abdominal wall defects resulting from surgical complications and unfavorable results of previous abdominal interventions. The purpose is not to discuss and analyze care and management of all soft tissue complications encountered after abdominal surgery, but to present the ones for which the plastic surgeon most likely will be asked to manage.

[Voluminous hemorrhagic cyst of the abdominal wall].

A case of great bleeding cyst formation in the abdominal wall is presented. Some aspects of differential diagnosis are discussed and the technique used to close the resultant hole in the intestinal wall after removing the cyst. The particular technical method they used permitted the reconstruction without using artificial materials.

[Influence of abdominal wall composition and thickness on ultrasound B scan].

Using a tissue-mimicking phantom and a computerised sonography system an ultrasound b scan analysis was performed. The images were acquired with different fat-muscle combinations as ultrasound wave path. These are simulations of a different composition or thickness of the abdominal wall. The analysis of the ultrasound images was performed using mathematical statistical parameters for ultrasound tissue characterisation. We examined the influence of the thickness or composition of the abdominal wall on ultrasound image brightness, microtexture and macrotexture. A dependence of ultrasound image brightness and microtexture on the thickness of the fat path was observed. Muscle tissue shows only a weak influence on the microtexture of the ultrasound image. These data demonstrate that a thick fat layer leads to a darker and diffuse image. This disturbs the evaluation e.g. of the liver parenchyma by analysis of the echo structure and may lead to false diagnoses especially in adiposity.

Treatment of the abdominal wall defects in an ambulatory surgical setting: our experience.

Introduction: The creation of Outpatient Surgery (OPS) units has allowed to reduce the costs and the waiting lists in an efficient fashion. We describe our series of patients operated on for abdominal wall defects, a pathology suitable for ambulatory surgery. Patients and methods: Between May 1994 and March 1998, 206 inguinal hernias, 23 femoral hernias, 47 umbilical-epigastric hernias and nine incisional hernias were operated on in an ambulatory surgical setting. The patients were selected following the selection criteria previously established (related to the patient, the environment and the surgical procedure). The average age was 45 years, and the distribution by sex, 210 men and 75 women. Spinal anesthesia was preferently performed. The surgical techniques employed were Lichtenstein's hernioplasty and Shouldice and Bassini procedures for inguinal hernias; Lichtenstein's plug technique for femoral hernias and simple closure or preperitoneal mesh for the middle line defects. Results: 44 patients needed readmitttance to hospital (failure of OPS), the most important causes being excessive pain, urinary retention and nausea/vomiting. There was no severe morbidity nor mortality. Conclusion: Surgery for abdominal wall defects constitutes a group of procedures suitable for efficient and low risk OPS programs.

A novel technique for gynecologic oncology surgery in the presence of abdominal wall mesh prosthesis.

Incisional herniae are relatively frequent complications of abdominal incisions. Hernia repair techniques have taken advantage of the strength provided by prosthetic mesh grafts. Subsequent surgery in these patients must incorporate a strategy for managing the mesh material. The goals are adequate exposure for surgery and a closure that restores wound strength. The current technique describes lateral dissection of the mesh prosthesis allowing for retraction of the mesh and adherent bowel, providing excellent surgical exposure. The mesh is reattached to the abdominal wall during closure. This technique allowed for staging procedures in a case of endometrial cancer and a case of ovarian cancer.

A simplified method of open laparoscopic entry and abdominal wall adhesiolysis.

We have developed a method of open laparoscopic abdominal entry and abdominal wall adhesiolysis. Key to this approach is the employment of digital pressure to effect intraumbilical peritoneal entry and local adhesiolysis before introducing any laparoscopic instruments. The technique is safe, rapid, and effective, and is easily reproduced. It is well suited to cases in which extensive abdominal adhesions are anticipated.

Transverse disruption of the abdominal wall--a tell-tale sign of seat belt related hollow viscus injury.

A pattern of injuries has been observed in five (5) female front seat passengers wearing seat belts. All were involved in high speed frontal impact motor vehicle accidents on country roads. Varying degrees of abdominal wall disruption involving fat, fascia or muscle, were universally associated with hollow viscus injury and right-sided rib fractures. Most patients had mesenteric or omental tears, flail chests and left clavicular injuries. Intimal tears of the distal aorta, right breast injuries and spinal injuries were also observed. The hollow viscus and mesenteric injuries may result from direct crushing, sudden rises of intraluminal pressure, or shearing forces acting at points of mesenteric attachments. At laparotomy it is recommended that necrotic or contused fascia and muscle be excised with primary abdominal closure and contused fat be excised or curetted and suction drainage applied to the subcutaneous tract. Abdominal wall disruption from seat belt trauma reflects the forces involved on impact and should alert the surgeon to the observed pattern of internal injuries.
