[An autopsy case of prostatic neuroendocrine cell carcinoma and adenocarcinoma initially found by brain and abdominal wall metastasis].

A 62 year-old man had been suffered from headache and left shoulder pain since March 1997. In November 1997, he visited our hospital complaining of work incapability, slow-moving and somnolence. Multiple nodular lesions were found in his brain and abdominal wall. Biopsy of the abdominal wall mass revealed small cell carcinoma/neuroendocrine cell carcinoma. Radiation therapy on brain and abdominal wall was done and these tumor nodules became decreased. However, recurrence and metastasis occurred later and died at March 1998. The autopsy revealed the origin of these tumors was the prostate. The prostatic tumors revealed neuroendocrine cell carcinoma mainly, combining a portion of adenocarcinoma. Most parts of the metastatic tumors were neuroendocrine cell carcinoma. Only the seventh thoracic vertebral metastasis was bone-sclerosing metastasis of adenocarcinoma.

One-stage repair of the anterior abdominal wall using bilateral rectus femoris myocutaneous flaps.

Total lower abdominal wall resection was required to remove a recurrent exophytic bladder carcinoma in a 36-year-old woman. The resulting 25 x 30-cm fascial defect was repaired with Marlex mesh. Bilateral rectus femoris myocutaneous flaps were rotated to close the 25 x 18-cm area of skin deficiency. These provided the advantages of robust cover of the lower abdominal wall in a single-stage procedure and primary closure of the donor sites.

Reconstruction of sternal and abdominal wall defects in a case of desmoid tumor.

A case of desmoid tumor of the anterior chest and abdominal wall is presented. The entire body of the sternum along with the upper abdominal wall and inner parts of both breasts was resected. The resulting defect over the pericardium and abdomen was reconstructed by the omentum and Marlex mesh. The large skin defect was covered by bilateral thoracoabdominal tube pedicles. The patient had a stable chest wall with uncompromised respiratory function 1 week after the operation. Prevention of local recurrences of desmoid tumors requires wide excision of the involved soft tissues and bony structures. The principles of wide resection of soft tissue tumors, reconstruction of the anterior chest and abdominal wall defects, and planning the skin coverage over the resulting defect are discussed.

Laparoscopy without pneumoperitoneum. Effects of abdominal wall retraction versus carbon dioxide insufflation on hemodynamics and gas exchange in pigs.

Laparoscopic surgery with CO2 insufflation is associated with adverse effects on hemodynamics and gas exchange. The abdominal wall retractor (AWR) is an alternative for pneumoperitoneum. Hemodynamics and gas exchange during the use of an AWR were compared to those of CO2 pneumoperitoneum. In eight pigs subjected to 1 h of CO2 pneumoperitoneum or abdominal wall retraction, hemodynamics, gas exchange, and oxygen transport were studied in a randomized cross-over study design. The only change observed during abdominal wall retraction was mild respiratory alkalosis. In contrast, during CO2 pneumoperitoneum mean arterial blood pressure increased 13%, central filling pressures doubled, and a small increase in cardiac output was observed. Peak airway pressures increased 50%, end-tidal CO2 increased 20%, and respiratory acidosis was induced (arterial pH from 7.46 +/- 0.07 to 7.31 +/- 0.06 and pCO2 from 33 +/- 3 mmHg to 53 +/- 4 mmHg). Arterial PO2 decreased but mixed venous oxygen saturation and oxygen consumption were unaffected. In contrast with CO2 pneumoperitoneum, laparoscopy using abdominal wall retraction was not associated with adverse effects on hemodynamics or gas exchange.

Abdominal wall expansion in congenital defects.

A method for expanding the skin, fascia, muscle, and peritoneal layers of the abdominal wall is described, and clinical application is demonstrated in two children with cloacal exstrophy and congenital absence of the lower half of the abdominal wall. This technique provides an innervated composite reconstruction of defects in excess of 50 percent of the abdominal surface and is recommended in large secondary defects where peritonealization has been achieved and in congenital defects that do not lend themselves to standard methods of closure. Cadaver dissection confirms that tissue expanders may be placed with preservation of innervation and blood supply to the abdominal wall.

Double-layer prostheses for repair of abdominal wall defects in a rabbit model.

The primary objective of this study was to compare the effectiveness of expanded polytetrafluoroethylene (e-PTFE) and polypropylene (PPM) in a rabbit abdominal wall defect model using a double-layer repair technique. Fifty-four New Zealand white rabbits had full thickness resection of a 5 x 5-cm segment of the mid portion of at the abdominal wall. The defect was repaired with two 6 x 6-cm layers of prosthesis in an underlay/overlay fashion incorporating a 1-cm edge of abdominal wall and grouped accordingly. Group I: inner and outer layer of PPM; Group II: inner layer e-PTFE, outer layer PPM; Group III: inner and outer layer e-PTFE. Animals from each group were sacrificed at 3, 6, and 12 months. The abdominal wall was assessed for herniations and bowel adhesions to the inner layer of the prosthesis. Adhesions were graded according to an adhesion scoring system (grade 0-3). No herniations were observed. Intestinal adhesions to PPM were quite dense at 3 months with a mean adhesion score of 2.5; at 12 months, adhesions were more dense and extensive, having a mean score of 3. Adhesions to e-PTFE were thin and filmy with a mean score of 0.4 at 3 months and 0.6 at 12 months (P < 0.001, 95% CI for each time period). Histologically, PPM fibers were consistently surrounded by dense fibrous connective tissue; foreign body giant cells were present. A thin connective tissue capsule covered the inner e-PTFE layer; its pores were progressively infiltrated by fibroblasts. The double-layer technique prevented hernias in all groups.(ABSTRACT TRUNCATED AT 250 WORDS)

Gasless laparoscopy-assisted colon surgery utilizing mini-laparotomy and a subcutaneous abdominal wall lift system.

BACKGROUND/AIMS: This study was performed to investigate the technical aspects and perioperative results of using a subcutaneous abdominal wall lift system for laparoscopy-assisted colectomy. METHODOLOGY: We attempted a laparoscopy-assisted colectomy for 19 patients and completed 16 cases using mini-laparotomy and a subcutaneous abdominal wall lift system, observing monitor images via laparoscopy or direct views through mini-laparotomy. All 5 surgeons had no experience of laparoscopy-assisted colectomy but considerable experience of laparoscopic cholecystectomy. RESULTS: The operating time ranged from 120 to 360 minutes with an average of 188. Intraoperative blood loss ranged from 20 to 300 mL with an average of 116 mL. No postoperative major complications occurred, but 5 cases suffered wound infection. CONCLUSIONS: Laparoscopy-assisted colon surgery utilizing a subcutaneous abdominal wall system and mini-laparotomy was feasible as minimally invasive surgery for colorectal diseases, even for surgeons with little previous experience.

Early reconstruction of the abdominal wall in giant omphalocele.

Omphalocele is the most common congenital defect of the abdominal wall. Mortality rate is between 20 and 70% and early closure of the abdominal wall, within 10 days of life, is vital to the successful outcome of the surgical treatment. The authors describe the use of two bipedicled flaps of abdominal skin to correct the defect of the midline as soon as the reduction of all viscera has been accomplished.

Anterior abdominal wall defects and biliary obstruction.

Three infants with anterior abdominal wall defects (gastroschisis and exomphalos) who presented with obstructive jaundice secondary to biliary obstruction, are described. All three infants had abnormal biliary systems, with mechanical distortion of the biliary tree. Biliary obstruction secondary to structural biliary anomalies should be considered in patients with abdominal wall defects and cholestasis, as prolonged unrelieved biliary obstruction may lead to biliary cirrhosis and portal hypertension.

Transdiaphragmatic pressure gradients and the lower esophageal sphincter after tight abdominal wall plication in the rat.

BACKGROUND: Gastroesophageal reflux (GER) is increasingly recognized as a complication of surgical closure of gastroschisis and omphalocele. AIM: This study tests the hypothesis that forceful abdominal wall closure reinforces the transdiaphragmatic pressure gradients that constitute the main GER-driving force and challenges the antireflux barrier. MATERIALS AND METHODS: Abdominal and esophageal pressures as well as lower esophageal sphincter pressures (LESP) and length (LESL) were measured in 17 adult rats before tight abdominal wall plication, after it, and 1 week later. RESULTS: This maneuver increased the transdiaphragmatic expiratory gradient from 0.67 +/- 1.31 to 6.97 +/- 2.68 mm Hg (P < .01) and the inspiratory gradient from 4.36 +/- 1.13 to 10.79 +/- 2.31 mm Hg (P < .01) by markedly increasing both the expiratory (from 1.47 +/- 0.74 to 9.44 +/- 1.85 mm Hg; P < .01) and inspiratory (from 0.98 +/- 0.69 to 6.83 +/- 1.55 mm Hg; P < .01) intraabdominal pressures. These changes were transient, and all pressures became normal after 1 week. The antireflux barrier functioned properly under these new conditions because both LESP and the diaphragmatic pinch-cock pressure (DPP) increased, from 20.3 +/- 3.63 to 26.5 +/- 4.31 mm Hg (P < .01) and from 16.4 +/- 7.25 to 22.5 +/- 4.36 mm Hg (P < .01), respectively, while LESL remained unchanged. CONCLUSION: Tight abdominal wall plication in the rat generates high intraabdominal pressures and thus reinforces the transdiaphragmatic pressure gradients, but these conditions elicit a healthy barrier response with sphincteric reinforcement. In addition, these changes are transient and fade out some time after operation. These facts should be taken into account for understanding the pathogenesis of GER after repair of abdominal wall defects in human babies.

The effect of mode of delivery on the perinatal outcome in fetuses with abdominal wall defects.

A descriptive study of 125 infants with abdominal wall defects was undertaken to determine the effect of mode of delivery on outcome. Fifty-six infants had gastroschisis and 69 had omphalocele. Overall, there were no differences between the omphalocele and the gastroschisis groups in either cesarean section rate (22% vs 26%) or prematurity rate (26% vs 30%). However, the omphalocele group had a significantly higher infant death rate (22% vs 7%, p less than 0.001), a significantly higher incidence of associated major congenital anomalies (29% vs 5%, p less than 0.001), and a higher incidence of long-term infant morbidity (14.5% vs 8.9%). Within either group there was no significant difference between vaginal and cesarean delivery regarding either infant mortality, acute or long-term infant outcome, or frequency of associated major anomalies. We conclude that vaginal delivery of infants with abdominal wall defects does not adversely affect infant outcome.

[Endometriosis of the abdominal wall after cesarean section].

The finding of endometriosis of the abdominal wall is a rare event; we describe three cases observed after cesarean section. The first case is an endometriosis of the rectus abdominis, first occurrence in literature. The second case describes a localization limited to the subcutaneous tissue. The third case describes the involvement of the entire abdominal wall. Only two patients complained about excruciating abdominal pain during menstrual bleeding. In one case pain was only an occasional event.

Primary actinomycosis of the anterior abdominal wall: case report and review of the literature.

Actinomycosis of the anterior abdominal wall is a rare infection caused by different Actinomyces species. We report a case of primary actinomycosis localized on the anterior abdominal wall, diagnosed by computed tomography (CT) scan, postoperatively confirmed by histopathological examination and treated by surgical resection combined with postoperative antibiotic therapy. The patient has been free of recurrence after 1 year. A review of the available literature is also presented.

Effects of inhalatory abdominal wall movement on vertical laryngeal position during phonation.

The configuration of the body resulting from inhalatory behavior is sometimes considered a factor of relevance to voice production in singing and speaking pedagogy and in clinical voice therapy. The present investigation compares two different inhalatory behaviors: (1) with a "paradoxical" inward movement of the abdominal wall, and (2) with an expansion of the abdominal wall, both with regard to the effect on vertical laryngeal position during the subsequent phonation. Seventeen male and 17 female healthy, vocally untrained subjects participated. No instructions were given regarding movements of the rib cage. Inhaled air volume as measured by respiratory inductive plethysmography, was controlled to reach 70% inspiratory capacity. Vertical laryngeal position was recorded by two-channel electroglottography during the subsequent vowel production. A significant effect was found; the abdomen-out condition was associated with a higher laryngeal position than the abdomen-in condition. This result apparently contradicted a hypothesis that an expansion of the abdominal wall would allow the diaphragm to descend deeper in the torso, thereby increasing the tracheal pull, which would result in a lower laryngeal position. In a post-hoc experiment including 6 of the subjects, body posture was studied by digital video recordings, revealing that the two inhalatory modes were clearly associated with postural changes affecting laryngeal position. The "paradoxical" inward movement of the abdominal wall was associated with a recession of the chin toward the neck, such that the larynx appeared in a lower position in the neck, for reasons of a postural change. The results suggest that the laryngeal position can be affected by the inhalatory behavior if no attention is paid to posture, implying that instructions from clinicians and pedagogues regarding breathing behavior must be carefully formulated and adjusted in order to ensure that the intended goals are reached.

[Abdominal wall closure techniques--the results of the Polish surgeons' survey].

AIM OF THE STUDY: The results of a survey designed to investigate abdominal wall closure techniques have been analyzed in this report. MATERIAL AND METHODS: The participants were asked to choose a method of abdominal wall closure in groups of patients with progressively increasing risk of wound healing complications. RESULTS: Sixty-nine surgeons responded (median age 41 years), with a median professional life of 15 years. In low and moderate-risk patients, abdominal wall closure plan was similar; the peritoneum and fascia would be closed separately. Continuous absorbable sutures were most frequently picked. Treatment option choices were more diversified in the high-risk group. No dominant surgical method could be found; different suturing materials were proposed, mainly in the form of interrupted sutures. In almost every third patient antieventration sutures were taken as a option. CONCLUSION: A correlation was found between the risk group and surgical technique, the use of interrupted/continuous sutures and anti-eventration sutures. Dexon, Vicryl and PDS were most frequently selected sutures by surgeons who responded to the survey.

[Desmoid tumor of the abdominal wall preoperatively suspected as urachal tumor: a case report].

A case of desmoid tumor of the abdominal wall which was preoperatively suspected as urachal tumor is presented. The patient was a 56-year-old man, who was referred to our clinic for further examination of the mass detected incidentally in the ventral region of the urinary bladder by computed tomography. Ultrasonography showed that the mass had a heterogenous and hypoechogenic content. An urachal tumor was suspected and surgery was performed to remove the tumor. During the operation we found that the tumor was completely separated from the urinary bladder and that it had originated from the left rectus abdominal muscle. The pathological diagnosis was desmoid tumor of the abdominal wall. Since urachal tumor has no characteristic findings on the imaging examinations, it is difficult to differentiate desmoid tumor of the lower abdominal wall from urachal tumor, preoperatively.

[Effects of tenoxicam on abdominal wall healing: experimental study in rats].

PURPOSE: To analyse the effect of tenoxicam, a nonsteroidal anti-inflammatory, on the abdominal wall healing in rats. METHODS: It was used 40 rats, submitted to longitudinal laparotomies, and allocated, randomly, in one control group (C), consisted of 20 rats treated with saline solution; and one test group (T), consisted of 20 rats treated with tenoxicam. The animals of each group were divided, according to their sacrifice day, into subgroups of 10 animals, named as C7, C14, T7 and T14. The numbers 7 and 14 indicated that the animal would be sacrificed on the 7th and 14th postoperative day, respectively. The tenoxicam (1 mg/ml) and saline solution (NaCl 0.9%) were administrated by intramuscular injections, at the dose of 0.6 ml/kg/day, immediately after surgery and continued for 4 days. In the sacrifice day, two segments of the abdominal wall (1 cm x 3 cm) were prepared and submitted to breaking strength measurement and hydroxyproline determination. RESULTS: No complications were observed in the four subgroups, including infection or dehiscence. There were no significant differences in the breaking strength measurement (p=0.262) and the hydroxyproline levels (p=0.392) among the four subgroups. CONCLUSION: The tenoxicam, administered intramuscularly, does not interfere on the abdominal wall healing of rats.

Management of the abdominal wall defect in the prune belly syndrome by muscle transposition: an 18-year follow-up.

Prune belly syndrome (PBS), an uncommon anomaly, consists of genito-urinary abnormalities and a partial or complete absence of abdominal wall musculature. Although the patient's genito-urinary problems are addressed, the attention currently directed toward the abdominal wall deficiency has been mostly aimed at improving the cosmetic appearance of patients and does little to replace the important functions of the musculature. These functions are the support of the viscera and their compression as well as the movement of the trunk. A case report with an 18-year follow-up is presented where thigh muscles were transposed to act as substitutes for the missing musculature. Although this presentation is based on a single case, it is intended to alert patients and physicians to a method of improving the lot of patients with PBS. In this patient, the result was very satisfactory. From being unable to move his trunk as a schoolboy before the surgical procedure, postoperatively he was able to participate in all school activities. As an adult, he is fully active and is a lead guitarist in a band. His excretory functions are normal and the scoliosis, present when first seen, has not progressed. It is suggested that consideration be given to the management of the abdominal wall deficiency in PBS by the transposition of muscle(s), because no alternative effective treatment directed to restoring absent muscle function appears to exist. Because the operative procedure is well tested and successful in adult patients who lose their abdominal wall musculature, the dissemination of this data appears to be necessary.
