Congenital defects of the gastrointestinal tract and abdominal wall. A three-year review.

One hundred forty-four infants with anomalies of the gastrointestinal tract and abdominal wall were treated at Children's Memorial Hospital between July 1970 and July 1973. The overall mortality, including unoperated infants and those dying from other causes up to six months later, was 17%. Associated defects, particularly of the heart and CNS, were the most common causes for death. Many infants were premature; however, this factor alone did not contribute to mortality. Differences in surgical technique did not affect mortality in patients with esophageal atresia, but one baby with total aganglionosis of his colon and two with gastroschisis may have survived with different modes of therapy. Although previous advances in pediatric surgery contributed to the overall good results in these infants, parenteral alimentation emerged as the single most important factor in improved survival during this study period.

[Abdominal wall abscess as a sequela of intraabdominal inflammation].

The author presents the case-histories of four abscesses of the abdominal wall, with a different cause in every patient. It is essential in the event of such purulent processes to seek their cause because only its elimination ensures a final solution of the case.

[Studies on the measurement of uterine contraction by the impedance-variance of maternal abdominal wall (author's transl)].

An electronic system for the detection of uterine contractions by impedance measurement of the maternal abdominal wall, where the placenta attached to the anterior uterine wall confirmed by using B-mode ultrasonic method, was evaluated in 74 subjects. Simultaneous recordings of uterine contractive activity with conventional external recording system were made. Impedance recordings were evaluated and compared with the external recordings. The available evidence from this study indicated that 88.31% of uterine contractions were accurately detected and the onset, peak and end of each uterine contractions was reliable parameters of impedance measurement. The uterine contractions which seemed to be weaker in second trimester and difficult to record by the usage of external method were clearly detectable by the method. However on the place of the maternal abdomen where the placenta was not attached, impedance recordings did not show corresponding response with each uterine contractions. It was indicated that impedance recordings on the localization of the placenta mainly represented the change of intraplacental blood volume following by uterine contractions. The advantages of this method consisted in the patients comfort and easy application of the recording electrodes, but the usefulness of the method was limited to the cases of anterior localization of the placenta, namely 50% of the whole pregnant women.

Transplantation of a segment of ileum to the external abdominal wall: an animal model of intestinal mucosal hyperplasia.

When a segment of small intestine is transplanted to the external abdominal wall in rats adaptive changes occur in the exposed mucosa. These probably represent an extreme example of a physiological response to one type of trophic influence--the effect of mechanical trauma. The nature of the changes has been studied at 7 weeks after externalization using simple morphometry and a number of cytokinetic techniques (thymidine labelling, vincristine-induced metaphase arrest and the fraction-of-labelled-mitoses method), and comparisons drawn with the normal ileum. The exteriorized mucosa showed marked villus atrophy and hyperplasia of the crypts to three times normal size as a result of increases both in crypt length and crypt circumference. Neither metaplastic nor dysplastic epithelial abnormalities were observed. Crypt-cell production rate doubled in the hyperplastic crypts due to an increase in the size of the proliferation zone within the crypt, and the distribution of proliferating cells within the crypt changed. But cell cycle times were prolonged and more maturing cells were retained in the hyperplastic crypts. The potential usefulness of this model, particularly in carcinogenicity studies is considered.

Subumbilical midline vascularity of the abdominal wall in portal hypertension observed at laparoscopy.

BACKGROUND: Large volume paracentesis is a common treatment of ascites. Injury to abdominal wall collateral veins during this procedure can lead to hemoperitoneum. Because of this concern, the midline below the umbilicus is often recommended as a site for paracentesis because of its presumed avascularity. METHODS: We examined the subumbilical peritoneal surface in 20 consecutive patients with liver disease undergoing diagnostic laparoscopy. This area was visualized by table tilting and confirmed by external finger compression. Nineteen patients had cirrhosis of various etiologies, and one had advanced fibrosis with evidence of portal hypertension. RESULTS: In these 20 patients, only 7 had avascular midlines below the umbilicus. Seven had small but definite veins running along the path of the urachus (median umbilical fold), and 6 had more prominent veins in this region. The internal landmarks in this region (median and medial folds) were frequently asymmetric with regard to the external appearance of the midline. CONCLUSION: The subumbilical midline in patients with portal hypertension is commonly vascular. When using this site for paracentesis, care should be exercised to identify venous structures with the narrow-gauge needle used to inject local anesthetic agent before placement of larger paracentesis needles.

Anterior abdominal wall--an unusual site for ectopic testis.

Testicular descent can be described in two phases, the transabdominal and the inguinoscrotal. During the inguinoscrotal phase, the testis may deviate from the normal path of descent and "migrate" to an abnormal location; this is called ectopic testis and is a relatively uncommon condition. The common sites for ectopic testes include the superficial inguinal pouch, the perineum, the opposite side of the scrotum, the femoral canal, and the pubopenile region. In addition to these well-recognized sites, preperitoneal and extracorporeal ectopic testes, which are extremely rare, have been reported. We report yet another rare site for ectopic testis, the anterior abdominal wall, probably the first of its nature to be reported in the English literature.

The effect of ultrasound-assisted liposuction and conventional liposuction on the perforator vessels in the lower abdominal wall.

Scientific reports of clinical in vivo research into the effects and side-effects of ultrasonic-assisted liposuction (UAL) are scarce. Advocates of UAL claim that the damage to vascular and nervous structures is limited and even less than with conventional and/or tumescent liposuction (CL). The effect of tumescent infiltration alone and combined with either CL or UAL was assessed by performing injection studies of the panniculus adiposus of the lower abdominal wall of 20 fresh cadavers and five abdominoplasty specimens. Besides the control and infiltration groups (n=5 in each), there was an additional group of ten cadaver flaps and five abdominoplasty flaps that underwent infiltration followed by UAL in the right half of the flap and infiltration followed by CL in the left half of the flap. Radiographs of these flaps were shown to a blinded panel of ten plastic surgeons, who were asked to evaluate and compare the damage on the basis of the number and magnitude of contrast-medium extravasations in the flap. Vascular damage to the perforating vessels was seen even after infiltration alone, although it was very limited. A variable amount of damage (ranging from little to extensive) was observed in the CL and UAL groups. Statistical analysis of the judgments of the observers could not show that either technique was less damaging than the other. UAL is, therefore, probably more beneficial to the surgeon than to the patient. The financial investment in the device is justified for surgeons with large liposuction practices, mainly, and probably solely, because of the reduced physical strain for the surgeon.

Abdominal-wall pseudohernia secondary to herpes zoster.

We present a case of a 78-year-old woman with abdominal-wall muscle paralysis following cutaneous herpes zoster in the T12-L1 dermatomes. An EMG confirmed paralysis, and a CT scan ruled out fascial defect. The paralysis had completely resolved 1 year later. A review of the literature regarding these unusual sequelae of herpes zoster is presented.

Porcine dermal collagen graft in abdominal-wall reconstruction.

We describe the use of a porcine dermal collagen graft in the reconstruction of a large abdominal-wall defect in a woman. The graft was not rejected and, after 1 year, was not associated with incisional hernia. This graft may become an alternative to synthetic-mesh and flap reconstructions because, despite being of a similar tensile strength, it promotes less adhesion, is incorporated into the host tissue and is less prone to infection.

Atrophy of the abdominal wall muscles after extraperitoneal approach to the aorta.

OBJECTIVE: We retrospectively assessed computed tomography (CT) scans to determine degree of anterolateral abdominal muscle atrophy in patients who underwent infrarenal aortic repair with 2 kinds of incisions for the extraperitoneal approach. METHODS: CT scans obtained before surgery and final scans obtained 2 to 100 months after surgery were assessed in 12 patients with paramedian incision (PM group) and 27 patients with flank incision (F group) who could be followed up at our hospital. We considered muscle thickness before surgery on the incision side to be 100% thickness (baseline value), and we calculated, by measuring the incision side after surgery, the corrected percent thickness (CPT%), which represents percentage of remaining muscle thickness that has escaped incision-induced atrophy. CT scans obtained at the level of the third (L3) and fifth (L5) lumbar vertebrae and the center of the sacrum (S) were selected for CPT% measurement. RESULTS: Duration from surgery to final CT scan was 2 to 65 months (mean +/- SD, 34.33 +/- 21.38 months) in PM group and 3 to 96 months (27.85 +/- 20.74 months) in F group. In PM group, mean CPT% values of the rectus abdominis muscle were 55.83 +/- 21.65% at L3, 35.50 +/- 10.79% at L5, and 31.92 +/- 11.00% at S; these values were statistically much smaller than baseline (P <.01). Mean CPT% values of the lateral abdominal muscles were not statistically different from baseline. In F group, mean CPT% values of the rectus abdominis muscle were 82.19 +/- 23.15% at L5 and 64.41 +/- 31.34% at S; these values were statistically smaller than baseline (P <.01). Mean CPT% values of the lateral abdominal muscles were 87.59 +/- 22.30% at L3 and 84.59 +/- 26.90% at L5; these values were statistically smaller than baseline (P <.05). CONCLUSIONS: Paramedian incision induced severe rectus abdominis muscle atrophy. Although flank incision induced various degrees of atrophy in both muscles, some patients had no muscle atrophy. These data indicate that further anatomic investigation into the relation between flank incision and abdominal wall innervation may contribute to prevention of muscle atrophy after flank incision.

Effects of basic fibroblast growth factor and phenytoin on healing of abdominal wall fascia and colonic anastomoses.

The aim of this study was to investigate the effects of basic fibroblast growth factor (bFGF) and phenytoin on wound healing in rats compromised by methylprednisone. This study was conducted in four groups consisting of 20 male Wistar rats. Rats in groups 2, 3, and 4 had a daily injection of methylprednisolone 5 mg/kg/day for 15 days. Laparotomy and sigmoid transsection were performed on day 15. In the postoperative period, rats in group 1 received no medication, group 2 received methylprednisolone 5 mg/kg/day intramuscularly, group 3 received bFGF 5 microg/kg on days 1-3 subcutaneously, and group 4 received phenytoin 40 mg/kg/day intraperitoneally. bFGF and phenytoin had a positive effect on tensile strength, hydroxyproline content, and wound healing parameters in abdominal wall fascia. In colonic anastomosis, phenytoin corrected all parameters, but bFGF had no effect.

[The bovine pericardium for closing abdominal wall defects].

A preparation procedure by making of biologic implants in their biologic texture was investigated in using closures of abdominal wall defects. Defects of the ventral trunk wall of 10 to 20 cm dimension were closed with a collagen implant of the equal size. The morphologic investigation was carried out after 12 respectively 24 months. The kind of the immigrated cells, the revascularisation, and the integration of the implants were criteria for the reutilization. Exclusive fibrocytes with regular cell density in the whole implant were provable after 12 months. The revascularization was demonstrable by numerous vessels and capillaries. The light-histologic findings were unchanged after 24 months, a distinction between implant and surrounding tissue was possible only in an electro-optical way.
