Introduction
The diaphragm may be injured by penetrating or blunt trauma. Diaphragmatic breach without visceral injury or herniation may be difficult to detect due to a paucity of clinical signs and herniation may be misdiagnosed following the erroneous interpretation of chest radiology. If not recognized there is a considerable risk of late morbidity and mortality. This prospective study reviews our experience with diaphragmatic injury in a busy general surgical service with a large trauma component.Methodology
A trauma database is maintained by the general surgical service of the Pietermaritzburg metropolitan complex. All patients who sustained a diaphragmatic injury between September 2006 and September 2007 were included in this study.Results
A total of 54 patients with diaphragmatic injury were treated in the period under review. There were three broad groups, namely those with simple breach of the diaphragm (37), acute diaphragmatic hernias (11) and chronic diaphragmatic hernias (6). Thirty-seven patients had a diaphragmatic breach confirmed at either laparotomy or laparoscopy. The mechanisms of injury were stab (24), gunshot wound (10), blunt trauma (2), and shotgun (1). There were seven (19%) deaths. In 19 asymptomatic patients laparoscopy was performed because of the presence of a stab wound to the left thoraco-abdominal region. Five (38%) of these patients were shown to have a diaphragmatic breach at laparoscopy. Eleven patients presented with an acute diaphragmatic hernia. The mechanisms of injury were stab (5), blunt trauma (5), and gunshot (1). The hernia contents were stomach (10), colon (1), and spleen (2). The operative approach was a laparotomy in 10 patients and a thoraco-laparotomy in one. Six patients presented with a chronic diaphragmatic hernia of longer than six months duration. The mechanisms of injury were stab (4), blunt trauma (1) and gunshot wound (1). The average delay from injury to presentation was 3.5 years. The contents were colon (3) and stomach (3). All were managed by laparotomy.Conclusion
If there is an established indication for laparotomy diaphragmatic breach is usually recognized and dealt with appropriately although failure to follow standard principles may result in the injury being overlooked. Isolated diaphragmatic injury without associated visceral damage cannot be diagnosed clinically or radiologically. Direct video-endoscopic inspection confirms or excludes the diagnosis and has a high pick up rate. Diaphragmatic herniation can present acutely after trauma or at a time remote from the original injury. Acute diaphragmatic injury may be confused with other pathologies and there is a risk of inappropriate intervention. Most diaphragmatic hernias can be repaired via laparotomy. 相似文献12.
IntroductionDiaphragmatic eventration, defined as permanent elevation of the diaphragm without defects, is a rare anomaly in adults. Trauma, neoplasms, infection, and degenerative disease are the most common causes of this condition, whereas idiopathic eventration of the diaphragm is relatively infrequent.Presentation of caseWe herein present the rare case of an 85-year-old female with idiopathic eventration of the bilateral diaphragm. The patient demonstrated a rapidly progressive course with dyspnea; therefore, thoracoscopic surgery of the unilateral diaphragm was performed. She subsequently withdrew from home oxygen therapy, which had introduced preoperatively, and exhibited a significant improvement in her pulmonary function for one year after the operation.DiscussionVarious approaches for diaphragmatic plication have been reported, including open (transthoracic or transabdominal) and minimally invasive methods, such as thoracoscopic or laparoscopic plication. We consider thoracoscopic plication to be an effective minimally invasive method, although single-lung ventilation is required.ConclusionWe experienced a case in which thoracoscopic plication of the unilateral diaphragm resulted in adequate objective improvements in the pulmonary function in a patient with idiopathic eventration of the bilateral diaphragm. 相似文献

OBJECTIVE: The use of laparoscopy in urology is increasing. Tumor of the kidney or adrenal gland and, in some cases, metastatic disease can involve the diaphragm. We describe the application of laparoscopic suturing techniques in the case of diaphragmatic involvement with a renal tumor. METHODS: After resection of the tumor and a small area of the diaphragm, a chest tube was placed under laparoscopic guidance. The tube was kept clamped until the end of the procedure. Decreasing intraabdominal pneumoperitoneum pressure made suturing easier with less tension on the edges of the diaphragmatic incision. Nonabsorbable interrupted horizontal mattress sutures were placed to close the diaphragmatic defect. RESULTS: The repair was uneventful; no intraoperative complications occurred. Extubation was done at the end of the procedure in the operating room. The chest tube was removed on postoperative day 2, and the patient was discharged on postoperative day 3. CONCLUSIONS: Laparoscopic repair of the diaphragm should be commensurate with traditional open surgical principles. In this regard, it is essential that surgeons interested in performing "advanced" laparoscopic oncologic surgery become facile in laparoscopic suturing. 相似文献

We examined the effect of enflurane on diaphragmatic contractility in six anesthetized mechanically ventilated dogs. The diaphragmatic force was assessed from transdiaphragmatic pressure (Pdi) developed at functional residual capacity against an occluded airway during cervical phrenic nerve stimulation. Pdi-stimulus frequency relationship was compared at three levels of anesthesia, namely 1, 1.5, and 2 MAC (minimum alveolar concentration) of enflurane. The sequence of changing anesthetic concentration was randomized between animals. Pdi at 50 and 100Hz stimulation was significantly decreased with increasing MAC while Pdi at 10Hz stimulation was not affected by the depth of anesthesia. Pdi of 20Hz stimulation was significantly decreased at 2 MAC as compared to those at 1 and 1.5 MAC. We conclude that enflurane decreases contractility of the diaphragm mainly through impairment of the neuromuscular transmission and/or membrane excitability. Part of its effects is, however, probably related to the impairment of excitation-contraction coupling, as suggested by the depression of Pdi at 2 MAC in response to 20Hz stimulation.(Kochi T, Ide T, Isono S et al.: Enflurane impairs canine diaphragmatic contractility in vivo.

We report a case of the female patient who was admitted to the hospital because of syncope experienced while climbing stairs. Diagnostic workup raised the suspicion of a right diaphragmatic rupture that was eventually confirmed by surgery (right-sided thoracotomy). Surgery also revealed tissue protruding through the rupture site from within the retroperitoneum that was proven subsequently to be a dedifferentiated liposarcoma. Second surgery was performed to completely remove the liposarcoma tissue and repair a coincident old right lumbar region hernia. The patient recovered fully. Spontaneous rupture of the diaphragm is rare and this is especially true for the right hemidiaphragm. We report the first case of diaphragmatic rupture caused by local infiltration by a retroperitoneal liposarcoma. This and similar reports emphasise that in cases with high clinical suspicion of diaphragmatic rupture, diagnosis should be pursued even in the absence of a preceding traumatic event. 相似文献

Laparoscopic cholecystectomy has now become the gold standard for the treatment of gallstone disease. Parallel with the conversion from the open to the laparoscopic technique, some complications peculiar to the laparoscopic approach have been experienced. Such a technique-related complication, resulting in an injury to the diaphragm and its repair during laparoscopic cholecystectomy is presented. 相似文献

Background and Aim
Recent reports in literature have emphasized the clinical perception of reduced pain, postoperative morbidity, and dysfunction associated with thoracoscopic approach compared with standard thoracotomy.The authors describe a thoracoscopic approach and technical details for diaphragmatic eventration repair in children.Patients and Methods
Ten patients, 4 girls and 6 boys, 1 teenager (14 years old) and 9 children (age range, 6-41 months; average, 17 months), were operated for a diaphragmatic eventration in 3 different pediatric surgery teams, according to the same technique. Symptoms were recurrent infection (7 cases), dyspnea on exertion (2 cases), and a rib deformity (1 case). An elective thoracoscopy was performed, patient in a lateral decubitus. A low carbon dioxide insufflation allowed a lung collapse. Reduction of the eventration was made progressively when folding and plicating the diaphragm. Plication of the diaphragm was done with an interrupted suture (6 cases) or a running suture (4 cases). The procedure finished either with an exsufflation (4 cases) or a drain (6 cases).Results
A conversion was necessary in 2 cases: 1 insufflation was not tolerated and 1 diaphragm, higher than the fifth space, reduced too much the operative field. Patients recovered between 2 and 4 days. Dyspnea disappeared immediately. Mean follow-up of 16 months could assess the clinical improvement in every patient.Discussion
Thoracoscopic conditions are quite different between a diaphragmatic hernia repair previously reported and an eventration. Concerning diaphragmatic hernias, reduction is easy, giving a large operative space for suturing the diaphragm. Concerning diaphragmatic eventrations, the lack of space remains important at the beginning of the procedure despite the insufflation into the pleural cavity. The operative ports must be high enough in the chest to allow a good mobility of the instruments. Chest drainage seems to be unnecessary.Conclusion
Diaphragmatic eventration repair by thoracoscopy is feasible, safe, and efficient in children. Above all, it avoids a thoracotomy. It improves the immediate postoperative results with a good respiratory function. 相似文献20.
