Hérnia traumática da parede abdominal

A rare case of blunt traumatic abdominal hernia is presented in which jejunal loops herniated through the abdominal wall. The patient had a serious motor vehicle accident seven years ago, while wearing the seat belt. He developed a traumatic hernia in the anterior lateral abdominal wall, which was operated, and relapsed after some months. The patient was reoperated and we observed the unattachment of the anterior lateral abdominal musculature from the ilium crest. After the hernial sac treatment, the defect was solved with the use of a polypropylene mesh. The postoperative evolution was good and four months later there were no signs of recurrence. Traumatic abdominal hernia remains a rare clinical entity, despite the increase in blunt abdominal trauma. Traumatic abdominal wall hernia falls into two general categories: small lower quadrant abdominal defects, typically the result of blunt trauma with bicycle handlebars, and larger abdominal wall defects related to motor vehicle accidents. The diagnosis may be often established by the physical examination alone. Conventional radiology and computerized tomography usefulness have been proved. In the vast majority of cases, early repair is recommended. The appropriate treatment is the reduction of the herniated bowel into the abdomen, the debridment of nonviable tissues, and a primary tension free closure of the detect.

Hérnia perineal após disjunçao da sínfise púbica: apresentação de caso e técnica para correção

Traunatic perineal hernia remains a rare clinical entity despite an overall increase in blunt trauma. Because of the incidence of other associated injuries, the mortality is high. Most of the perineal defects are repaired during the orthopaedics surgery to reconstitute the pelvis and few patients develop a true perineal hernia without pelvic instability. A 80-year-old woman was involved in a running over accident with disjunction of pubic symphysis, dislocation of sacrum-iliac junction and fracture of pubis and ischium. The patient was submitted to an orthopaedic surgery and latter development an perineal hernia through the genitalia. The diagnosis could be established with physical examination alone. Conventional radiology, computadorized tomography, and ultrasound should also be done to progran the surgery. The repair approach was performed using a marlex mesh, fixed in the pelvic bones, Cooper ligament, and the abdominal wall. The mesh was stood in a retro- peritoneal position, rebuilding the pelvic floor without reconstruction the pelvic bones. We conclude that this is an efficient approach to repair of traumatic postoperative perineal hernia, mainly in patients with high operative risk, when the osseous repair is not necessary.

Correção laparoscópica de hérnia diafragmática traumática crônica

Diaphragmatic hernia secondary to blunt or penetrating trauma is rarely by itself a fatal event. However, if unpercieved, it may lead to severe complications caused by herniation of abdominal contents to the ethorax. Blunt trauma related to car accidents is the most frequent cause of diaphragmatic hernias. Associated injuries are frequently observed, provoked by severe traumas of great impact. These blunt trauma hernias occur mainly on the left side due to abdominal anatomy, since the liver is usually located on the right side. When injuries are observed on the right they tend to be more severe, generally related to major trauma of solid organs. Less frequently diaphragmatic hernias may be bilateral. The management of diaphragmatic injury would appear to be a simple matter of suturing the defect. However, peroperative diagnosis can be difficult and even at the time of surgery some diaphragmatic injuries can be overlooked if carefull exploration is not done. Associated injuries tend to divert attention from the diaphragmatic injury. Laparoscopic diagnosis and repair have been described with successfull. Laparotomy or thoracotomy can be employed for surgical repair of traumatic diaphragmatic hernias. Standard (laboratory/imaging) examinations may fail to make the diagnosis. Recently, the laparoscopic approach has proved useful for more precise evaluation of such injuries, very often allowing immediate repair of these lesions.

Hérnia diafragmática traumática crônica e fístula gastropleurocutânea

Traumatic diaphragmatic hernia is defined as a laceration of the diaphragm with an abdominal viscera herniation into the thorax. It is usually asymptomatic, with the exception of the cases with obstruction, strangulation, necrosis or perforation of the herniaded viscera. It is classified as acute, latent or chronic, in accordance with the evolutive period. At the latent phase, symptoms are indefinite and the radiological signals, which are suggestive of thoracic affections, are frequent and can induce a diagnosis error, leading to inadequate treatment.This article presents a case of chronic traumatic diaphragmatic hernia which was complicated by a gastricpleuralcutaneous fistula, due to an inadequate thoracic drainage. Considering that this is a chronic affection with an unquestionable surgical indication, due to the complications risk, it is essential to have a detailed diagnostic investigation, which aims at both avoiding an intempestive or inadequate therapeutics behaviour and reducing the affection morbimortality. Recently, the videolaparoscopic approach has proved to be more precise when compared to the other diagnostic methods, by direct visualization of the diaphragmatic laceration, allowing its correction by an immediate suture.

Hérnia diafragmática traumática

Traumatic diaphragmatic hernia is an uncommon but important problem in the patient with multiple injuries. Since diaphragmatic injuries are difficult to diagnose, those that are missed may present with latent symptoms of bowel obstruction and strangulation. The same may occur in the patients with stab wounds to the lower chest. Traumatic diaphragmatic hernia should be suspected on the basis of an abnormal chest radiograph in the trauma victim with multiple injuries. This article discuss about history, epidemiology, clinical signs and symptoms, diagnostic modalities, treatment and complications.

Hérnia traumática do pulmão

Traumatic lung herniation is an unusual clinical problem. We present a case of a large left post-traumatic lung hernia on the left, anterior, second intercostal space following blunt chest trauma. An important factor in the etiology of these lesions is the relative lack of muscular support of the anterior part of the chest. This report describes the diagnosis and management of a post-traumatic lung hernia.

Immunohistochemical evaluation of fibrillar components of the extracellular matrix of transversalis fascia and anterior abdominal rectus sheath in men with inguinal hernia

OBJECTIVE: to evaluate the role of fibrillar extracellular matrix components in the pathogenesis of inguinal hernias. METHODS: samples of the transverse fascia and of the anterior sheath of the rectus abdominis muscle were collected from 40 men aged between 20 and 60 years with type II and IIIA Nyhus inguinal hernia and from 10 fresh male cadavers (controls) without hernia in the same age range. The staining technique was immunohistochemistry for collagen I, collagen III and elastic fibers; quantification of fibrillar components was performed with an image analysis processing software. RESULTS: no statistically significant differences were found in the amount of elastic fibers, collagen I and collagen III, and the ratio of collagen I / III among patients with inguinal hernia when compared with subjects without hernia. CONCLUSION: the amount of fibrillar extracellular matrix components did not change in patients with and without inguinal hernia.

Acute renal failure due to abdominal compartment syndrome: report on four cases and literature review

We report on 4 cases of abdominal compartment syndrome complicated by acute renal failure that were promptly reversed by different abdominal decompression methods. Case 1: A 57-year-old obese woman in the post-operative period after giant incisional hernia correction with an intra-abdominal pressure of 24 mm Hg. She was sedated and curarized, and the intra-abdominal pressure fell to 15 mm Hg. Case 2: A 73-year-old woman with acute inflammatory abdomen was undergoing exploratory laparotomy when a hypertensive pneumoperitoneum was noticed. During the surgery, enhancement of urinary output was observed. Case 3: An 18-year-old man who underwent hepatectomy and developed coagulopathy and hepatic bleeding that required abdominal packing, developed oliguria with a transvesical intra-abdominal pressure of 22 mm Hg. During reoperation, the compresses were removed with a prompt improvement in urinary flow. Case 4: A 46-year-old man with hepatic cirrhosis was admitted after incisional hernia repair with intra-abdominal pressure of 16 mm Hg. After paracentesis, the intra-abdominal pressure fell to 11 mm Hg.

The Stoppa procedure in inguinal hernia repair: to drain or not to drain

OBJECTIVE: The objective of this study is to evaluate the benefits of drainage in the Stoppa procedure for inguinal repair. PATIENTS AND METHODS: The use of a suction drain was randomized at the end of the surgical intervention in 26 male patients undergoing inguinal hernia repair, divided into 2 groups: Group A, 12 patients undergoing drainage, and group B, 14 patients not undergoing drainage. On the second postoperative day, all patients underwent abdominal pelvic computed tomography scan examination to detect the presence of abdominal fluid collection. RESULTS: In group A, no patient developed fluid collection in the preperitoneal space, and 1 patient presented with an abscess in the preperitoneal space on the 15th postoperative day. In group B, 12 patients presented with fluid collections in the preperitoneal space on computed tomography scan evaluation. However, only 3 patients presented minor complications. None of the patients developed a major complication. CONCLUSION: The use of suction drainage with the Stoppa procedure does not provide any benefit.

Arma branca retida em aorta abdominal superior

Abdominal aorta wounds carries a high immediate mortality. Few patients reach hospital care alive. There are no reports on Medline (1969-2002) about aortic wounds of foreign body with retention. A case with upper abdominal aortic wound with an inlaid blade is reported. The retained blade fixed the stomach to the surgical field, difficulting the vascular control, leading to an unconventional approach and allowing extensive contamination. The patient developed multiple organ dysfunction and died at fifth postoperative day. Singularities of an inlaid knife in upper abdominal aorta and changes in traditional approach are discussed. The authors assumed that the inlaid knife decreased the bleeding, allowing the patient arrival to the hospital, but worsened the approach to the aorta wound.

Colecistite aguda decorrente de hemorragia intraluminar da vesícula biliar após trauma abdominal fechado

Isolated gallbladder injury following abdominal blunt trauma is rare and early diagnosis is difficult to make, particularly when no other organ is injured. However, ultrasonography is valuable for investigating gallbladder injuries. We report a case of isolated gallbladder blunt trauma presented as acute cholecystitis with hemobilia. In isolated blunt traumatic injury to the gallbladder, treatment options vary depending on the specific injury. The characteristics of blunt trauma injuries to the gallbladder and their appropriate management are discussed.

O uso da prótese na correção das hérnias da parede abdominal é um avanço, mas o seu uso indiscriminado, um abuso

The objective is to alert the surgeon about the indiscriminate use of synthetic prosthesis in the correction of inguinal and incisional hernias. The authors provide a brief history of surgery on hernias and a review of the literature, showing the importance of classifying inguinal hernias to fit the type of surgical correction with the defect found, abstaining from treating all hernias, with the same type of surgical procedure. In our opinion, small indirect inguinal hernias (type 1 and 2 of Gilbert) and hernias in women must not, in general, be treated with prostheses. The synthetic material should be reserved for direct and large indirect hernias. Even so, this attitude, besides determining a higher cost for the procedure, can lead to important complications such as infection, rejection, fistula formation, chronic pain, alterations in spermatogenesis and the possibility of carcinogenesis, according to more recent reports. The physiology and anatomy of the abdominal wall should be considered when dealing with incisional hernia corrections, where the surgeon can choose among many techniques to correct those defects, and in selected cases, utilize synthetic material. We conclude that although the use of biomaterials has constituted a great advance in surgery for abdominal wall hernia corrections because they decrease recurrences, and permit treatment of large abdominal hernias, the indiscriminate prosthesis usage is an abuse, and it can determine many serious complications, certainly avoidable with a well indicated non mesh technique .

Nova técnica para o fechamento dinâmico da parede abdominal

Os avanços nos cuidados com o paciente traumatizado e com infecções abdominais graves são responsáveis por um número crescente de peritoneostomias. O manejo desta entidade é complexo e várias técnicas foram descritas para seu tratamento. Recentemente foi introduzido na literatura o conceito de fechamento dinâmico da parede abdominal, com elevadas taxas de sucesso. O objetivo deste trabalho é de servir como nota prévia de uma nova abordagem para o tratamento das peritoneostomias, desenvolvida no Hospital Universitário da Universidade de São Paulo. Trata-se de um procedimento simples e de baixo custo, facilmente realizado por cirurgião geral. O procedimento também foi utilizado como reforço em fechamentos abdominais tensos, de maneira profilática. O procedimento é descrito em detalhes, assim como os resultados nos primeiros pacientes. Apesar de promissora, refinamentos técnicos e estudos complementares são necessários para a validação da técnica.

Temporary abdominal closure with zipper-mesh device for management of intra-abdominal sepsis

OBJECTIVE: to present our experience with scheduled reoperations in 15 patients with intra-abdominal sepsis. METHODS: we have applied a more effective technique consisting of temporary abdominal closure with a nylon mesh sheet containing a zipper. We performed reoperations in the operating room under general anesthesia at an average interval of 84 hours. The revision consisted of debridement of necrotic material and vigorous lavage of the involved peritoneal area. The mean age of patients was 38.7 years (range, 15 to 72 years); 11 patients were male, and four were female. RESULTS: forty percent of infections were due to necrotizing pancreatitis. Sixty percent were due to perforation of the intestinal viscus secondary to inflammation, vascular occlusion or trauma. We performed a total of 48 reoperations, an average of 3.2 surgeries per patient. The mesh-zipper device was left in place for an average of 13 days. An intestinal ostomy was present adjacent to the zipper in four patients and did not present a problem for patient management. Mortality was 26.6%. No fistulas resulted from this technique. When intra-abdominal disease was under control, the mesh-zipper device was removed, and the fascia was closed in all patients. In three patients, the wound was closed primarily, and in 12 it was allowed to close by secondary intent. Two patients developed hernia; one was incisional and one was in the drain incision. CONCLUSION: the planned reoperation for manual lavage and debridement of the abdomen through a nylon mesh-zipper combination was rapid, simple, and well-tolerated. It permitted effective management of severe septic peritonitis, easy wound care and primary closure of the abdominal wall.

Use of surgical mesh of different compositions in the correction of the abdominal wall defect in rats

Objective: To analyze the performance of two surgical meshes of different compositions during the defect healing process of the abdominal wall of rats. Methods: thirty-three adult Wistar rats were anesthetized and subjected to removal of an area of 1.5 cm x 2 cm of the anterior abdominal wall, except for the skin; 17 animals had the defect corrected by edge-to-edge surgical suture of a mesh made of polypropylene + poliglecaprone (Group U - UltraproTM); 16 animals had the defect corrected with a surgical mesh made of polypropylene + polidioxanone + cellulose (Group P - ProceedTM). Each group was divided into two subgroups, according to the euthanasia moment (seven days or 28 days after the operation). Parameters analyzed were macroscopic (adherence), microscopic (quantification of mature and immature collagen) and tensiometric (maximum tension and maximum rupture strength). Results : there was an increase in collagen type I in the ProceedTM group from seven to 28 days, p = 0.047. Also, there was an increase in the rupture tension on both groups when comparing the two periods. There was a lower rupture tension and tissue deformity with ProceedTM mesh in seven days, becoming equal at day 28. Conclusion : the meshes retain similarities in the final result and more studies with larger numbers of animals must be carried for better assessment.
