1/18. Incisional hernia and fascial defect following laparoscopic surgery.Complications involving the abdominal wall, particularly incisional hernias, were not expected when laparoscopic procedures were first introduced. With the increasing number of laparoscopies in abdominal surgery, more incisional hernias are observed. The authors report 13 cases of umbilical incisional hernia, which occurred late after laparoscopic cholecystectomy, and one case of omental procidentia through a lateral port, which occurred early after laparoscopic hernia repair with the transabdominal preperitoneal technique. There are 4 men and 10 women (mean age, 59.8 years; range, 40-74 years). Between March 1991 and December 1997, a total of 1,287 patients underwent laparoscopic operations at the Surgical Department of the Gradenigo Hospital in Turin, italy. Incisional hernia incidence is 1%. risk factors, such as chronic bronchitis or weight increase, which give rise to endoabdominal pressure, are present in some cases. malnutrition may have a major role in many cases. calculi larger than 15 mm are also seen frequently. Postlaparoscopy incisional hernia is generally a minor complication--only once did its occurrence cause a strangulated hernia. All precautions, including fascial suturing, must be taken to reduce the 1% incidence of postoperative incisional hernias.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
2/18. Silo reduction of giant omphalocele and gastroschisis utilizing continucous controlled pressure.A method is described utilizing continuous controlled pressure to achieve smooth, rapid, and safe silo reduction of an anterior abdominal-wall defect. A metal tube with larger wheels at each end is suspended by runners and counterweights to slowly roll the silo and squeeze the contents into the abdominal cavity.- - - - - - - - - - ranking = 5keywords = pressure (Clic here for more details about this article) |
3/18. Left-lung-collapse bronchial deformation in giant omphalocele.Five infants with giant omphalocele had persistent collapse of the left lung and required prolonged respiratory support. Narrowing of the left main bronchus, reversible with positive end-expiratory pressure, was identified radiographically in 3 infants, and we postulate that this relates to distortion of the bronchus within the constraints of the elongated, narrow thoracic cavity characteristic of these patients. The lung collapse may be precipitated by manipulation (reduction or attempted reduction) of the omphalocele.

4/18. Management of neglected giant omphalocele with Gore-tex in a child aged 8 years.Omphalocele is a disease of neonatal age and its present management is successful in almost all specialized centers of Pediatric Surgery. A case of an 8-year-old girl who was managed with conservative treatment during her neonatal period with mercurochrome (Grob method) is presented. Due to very serious congenital cardiopathy, a corrective operative procedure of the omphalocele was not feasible during neonatal age. However, following successful heart surgery the child grew up with her initial disorder. The child was first seen in our clinic at the age of 5 years, presenting with a very large omphalocele. Following a staged pressure of the abdomen with a special belt an attempt was made to close the ventral hernia successfully using a Gore-tex sheet.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
5/18. Umbilical and bilateral inguinal hernias in a veteran powerlifter: is it a pressure-overload syndrome?Umbilical, inguinal and hiatal hernias are all thought to occur from basically the same etiology, a malformation in the tissue leading to herniation. The mechanisms for these malformations range from congenital to degenerative. Earlier studies proposed that hiatal hernias result from age-related degenerative changes in the phrenoesophageal ligament leading to subsequent herniation. We found that hiatal hernias occur in young power athletes secondary to intra-abdominal pressure overload of the phrenoesophageal ligament. We present a case of umbilical and bilateral inguinal hernias occurring in a veteran powerlifter. The pathogenesis of multiple hernias and the physiological pressure systems involved in the development of multiple hernias in a power athlete are discussed.- - - - - - - - - - ranking = 6keywords = pressure (Clic here for more details about this article) |
6/18. adult umbilical hernia with vertical dislocation.We present a case of adult umbilical hernia with vertical dislocation along the abdominal wall. The hernial sac arose from the internal ring and connected to the umbilicus 20 mm below the internal ring. The postoperative course was uneventful. Two years and four months after the operation there was no evidence of recurrent hernia even when abdominal pressure was increased, and the umbilicus looked acceptable. An umbilical hernia is usually within the umbilicus. The hernial sac arose from the internal ring so should be called an umbilical hernia not an epigastric hernia. It is unusual that the umbilical hernia dislocates vertically along the abdominal wall, while the umbilicus stays depressed. This atypical form of umbilical hernia has not been described previously as far as we know.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
7/18. Management of ventral hernia after giant exomphalos with external pressure compression using helmet device.PURPOSE: The aim of this study was to evaluate an alternative technique of reducing a ventral hernia that follows the primary conservative treatment of a giant omphalocoele. methods: The patient is a full-term male neonate with a giant exomphalos. Initially triple dye was applied as an eschar-inducing agent. This resulted in a ventral hernia after 1 month. It was decided to achieve expansion of the abdominal cavity based on the principle of external pressure compression using a sphygmomanometer cuff over the hernia. The cuff was worn continuously, and manual pressure was applied daily. Care was taken to avoid intraabdominal hypertension using the reading of the manometer that was attached. The external pressure was corroborated with observations of respiration and circulation. RESULTS: The child did not show any ill effects of raised intraabdominal pressure. Throughout the treatment, the child was on full oral feedings and did not require any ventilator support. Reduction of the ventral hernia was achieved in 9 months. Surgical repair of the residual hernia defect was carried out by double breasting of the fascia. CONCLUSIONS: The application of controlled external pressure using a specially constructed device is a safe, noninvasive, and effective method of achieving reduction of a ventral hernia after primary conservative treatment of a giant omphalocoele.- - - - - - - - - - ranking = 9keywords = pressure (Clic here for more details about this article) |
8/18. Use of Teflon mesh for repair of abdominal wall defects in neonates.Since 1975, we have employed Teflon mesh sutured to the fascial rim in four newborns with giant omphaloceles, with approximation of skin flaps over the mesh. By stabilizing the anterior abdominal wall, the Teflon mesh has prevented formation of large ventral hernias. The mesh has been retained in place for a year or longer, until the growth of the child permits excision of the prosthesis and fascial approximation without difficulty. A similar technique has been successfully employed in a fifth neonate following transabdominal correction of congenital bilateral eventration of the diaphragm to avoid unacceptable increase in intra-abdominal pressure with primary closure of the abdominal wall. The Teflon mesh appears ideally suited for this technique. It is well incorporated into the fascial rim with minimal foreign body reaction. At the time of secondary repair, the mesh can easily excised from the smooth underlying pseudomembrane covering the bowel. All infants achieved stable abdominal walls by this technique. Three patients have undergone excision of the Teflon mesh and fascial repair at 12, 15, and 36 mo of age without difficulty.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
9/18. vacuum-assisted closure: a new method for treating patients with giant omphalocele.INTRODUCTION: Closure of giant omphalocele can present a surgical challenge. Neither silo, skin flap, nor primary closure has been successful in treating all patients. We present a novel application of the vacuum-assisted closure (VAC) device, which allows for improved results in these difficult cases. methods: The VAC device (KCI, San Antonio, Tex) consisted of a sponge applied directly to the bowel and liver, covered with impermeable transparent dressing, and attached to a low negative pressure system. The sponge was changed every 3 to 5 days under local sedation. patients: All 3 patients had giant omphaloceles. The first infant, a 34 week gestational age (WGA) male, was initially treated with silo reduction, which disrupted after 21 days. The large mass of bowel and liver made primary closure impossible. The VAC was applied for 45 days. The viscera was easily reduced and subsequently covered with acellular dermal matrix (AlloDerm). The VAC was reapplied, and the small remaining defect was skin-grafted. The second male infant was a 34 WGA male infant who became septic after failure of prosthetic mesh closure. The VAC was applied for 22 days after removal of the mesh. The infection resolved, and the defect size was reduced, allowing for skin flap closure. Mesh infection and development of an enterocutaneous fistula in the last patient, a 37 WGA female child, were treated by mesh removal and application of the VAC for 36 days. The VAC allowed for control of the fistula output and development of a healthy granulation bed. RESULTS: vacuum-assisted closure was associated with (1) rapid shrinkage and reduction of the viscera (22-45 days); (2) cleansing of the wound; (3) excellent granulation; (4) maintenance of a sterile environment; and (5) ease of use, with changes possible at the bedside. CONCLUSION: The VAC device should be considered a safe and effective alternative in treating complicated cases of giant omphalocele until a more definitive closure method can be used.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
10/18. Negative pressure wound therapy to treat peri-prosthetic methicillin-resistant staphylococcus aureus infection after incisional herniorrhaphy. A case study and literature review.The preferred treatment for incisional hernias occurring post laparotomy involves use of prosthetic mesh. If this mesh becomes infected, it may have to be removed to achieve wound healing. A patient with a methicillin-resistant staphylococcus aureus-infected prosthetic mesh received negative pressure wound therapy to help facilitate healing without removing the prosthetic mesh applied to manage his hernia. After almost 4 weeks of treatment, the wound was closed secondarily. The literature contains many case studies about the use of NPWT for a variety of wounds but information about its safety and effectiveness for managing methicillin-resistant staphylococcus aureus-infected prosthetic mesh is limited. The results of this case study add to the evidence that controlled clinical studies are warranted.- - - - - - - - - - ranking = 5keywords = pressure (Clic here for more details about this article) |
