Giant omphaloceles with a small abdominal defect: prenatal diagnosis and neonatal management. (25/153)

A giant omphalocele is a liver-containing protrusion through an abdominal defect wider than 5 cm in diameter. The giant form with a small abdominal wall defect is a rare condition which, to our knowledge, has not been described previously. We describe three cases with the typical features of elongated vascular liver pedicle and angiomatosis of the hepatic portal system. The abnormal liver organogenesis, due to extra-abdominal development, represented a significant risk factor for hepatic thrombosis after visceral reduction and liver rotation. All the neonates underwent surgery on the first day of postnatal life. One died because of a postoperative liver infarction, and the survivors needed prolonged respiratory support. Prenatal sonographic features, timing, delivery, type of surgical repair, and postnatal outcome are reviewed. A prenatal sonographic diagnosis could be useful to evaluate the abdominal ring and serial ultrasound examinations are recommended to detect promptly ominous signs of hepatic and bowel damage. Color Doppler may be useful to assess the anatomy of the abdominal vessels and their relationships with the herniated organs, although it was not used in any of the cases reported here. This congenital malformation might be considered as a pathological entity separate from giant omphalocele with large abdominal defect, with a severe prognosis due possibly to its different embryological development.  (+info)

Heated, humidified CO2 gas is unsatisfactory for awake laparoscopy. (26/153)

BACKGROUND: The necessity for general anesthesia represents an impediment to using a laparoscopic approach for some procedures that are otherwise performed with the patient under local anesthesia using a conventional open technique. Heating and humidifying the insufflation gas reportedly reduces perioperative pain associated with a CO2 pneumoperitoneum, thus enabling awake laparoscopy. METHODS: Two cases are reported herein of laparoscopy performed with the patient under local anesthesia using heated, humidified CO2 gas for the pneumoperitoneum. RESULTS: Both patients experienced pain with insufflation of heated, humidified CO2 gas of sufficient magnitude that the procedure could not be performed. The CO2 gas was washed out and replaced with helium gas insufflation with complete resolution of pain. The laparoscopic procedures were accomplished without further discomfort with local anesthesia and using a helium gas pneumoperitoneum. CONCLUSIONS: Heated, humidified CO2 gas insufflation does not reduce pain sufficiently to permit satisfactory performance of laparoscopy with local anesthesia, especially when full volume insufflation is required. Cold, dry helium gas produces no pain. The theory that cold, dry insufflation gas is a source of peritoneal pain during laparoscopy needs to be reassessed.  (+info)

An unusual abdominal wall hernia. (27/153)

An unusual hernia is described involving a defect in the right rectus sheath at the junction of its middle and lower third. This was associated with an extension of the sac anteriorly between the right rectus muscle and its overlying sheath.  (+info)

Negative pressure wound therapy to treat peri-prosthetic methicillin-resistant Staphylococcus aureus infection after incisional herniorrhaphy. A case study and literature review. (28/153)

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.  (+info)

Topical applications of chlorhexidine to the umbilical cord for prevention of omphalitis and neonatal mortality in southern Nepal: a community-based, cluster-randomised trial. (29/153)

BACKGROUND: Omphalitis contributes to neonatal morbidity and mortality in developing countries. Umbilical cord cleansing with antiseptics might reduce infection and mortality risk, but has not been rigorously investigated. METHODS: In our community-based, cluster-randomised trial, 413 communities in Sarlahi, Nepal, were randomly assigned to one of three cord-care regimens. 4934 infants were assigned to 4.0% chlorhexidine, 5107 to cleansing with soap and water, and 5082 to dry cord care. In intervention clusters, the newborn cord was cleansed in the home on days 1-4, 6, 8, and 10. In all clusters, the cord was examined for signs of infection (pus, redness, or swelling) on these visits and in follow-up visits on days 12, 14, 21, and 28. Incidence of omphalitis was defined under three sign-based algorithms, with increasing severity. Infant vital status was recorded for 28 completed days. The primary outcomes were incidence of neonatal omphalitis and neonatal mortality. Analysis was by intention-to-treat. This trial is registered with , number NCT00109616. FINDINGS: Frequency of omphalitis by all three definitions was reduced significantly in the chlorhexidine group. Severe omphalitis in chlorhexidine clusters was reduced by 75% (incidence rate ratio 0.25, 95% CI 0.12-0.53; 13 infections/4839 neonatal periods) compared with dry cord-care clusters (52/4930). Neonatal mortality was 24% lower in the chlorhexidine group (relative risk 0.76 [95% CI 0.55-1.04]) than in the dry cord care group. In infants enrolled within the first 24 h, mortality was significantly reduced by 34% in the chlorhexidine group (0.66 [0.46-0.95]). Soap and water did not reduce infection or mortality risk. INTERPRETATION: Recommendations for dry cord care should be reconsidered on the basis of these findings that early antisepsis with chlorhexidine of the umbilical cord reduces local cord infections and overall neonatal mortality.  (+info)

Walking with continuous positive airway pressure. (30/153)

A ventilator-dependent child had been in the paediatric intensive care unit (PICU) ever since birth. As a result, she had fallen behind considerably in her development. After 18 months, continuous positive airway pressure was successfully administered via a tracheostomy tube with a novel lightweight device. This enabled her to walk in the PICU. With this device, the child was discharged home where she could walk with an action range of 10 m. Subsequently, her psychomotor development improved remarkably. To the authors' knowledge, this is the first case report of a patient, adult or paediatric, who could actually walk with a sufficient radius of action while receiving long-term respiratory support.  (+info)

Laparoscopic repair of umbilical hernias in conjunction with other laparoscopic procedures. (31/153)

BACKGROUND: This study evaluates the feasibility of laparoscopic transfascial suture repair of umbilical hernias when combined with another laparoscopic procedure that potentially contaminates the peritoneal cavity. METHOD: From August 1997 to November 2001, 32 patients underwent laparoscopic umbilical suture repair in association with another laparoscopic procedure. The repair was performed with the Carter-Thomason suture passer. RESULTS: Of the 32, 26 patients with more than 1-year follow-up were included in the study. The mean diameter of the umbilical hernia defect was 1.67 cm (range, 0.5 to 3). At a mean follow-up of 34 months (range, 12 to 60), there were only 2 recurrences (7.7%) both of which happened in patients with hernia defects larger than 2 cm in diameter. Apart from 2 wound infections, no other complications occurred. CONCLUSION: Laparoscopic suture repair of umbilical hernias with the suture passer method is effective and durable even when combined with other laparoscopic procedures that potentially contaminate the peritoneal cavity with bile or enteric contents.  (+info)

Umbilical varix presenting as an incarcerated umbilical hernia--a costly mistake if not recognised. (32/153)

Incarcerated umbilical hernias commonly present as emergencies. Often they are diagnosed clinically and repaired surgically. In the case reported here, surgery could have been complicated by a major haemorrhage. An accurate history, high index of suspicion and attention to detail are paramount.  (+info)
