Summary Obturator hernias comprise a rare group of abdominal hernias. They are often diagnosed when the small bowel has become obstructed
and the patients are operated on without the causes of the obstruction being known. Although many techniques for closure of
the defect are available, there is no agreement at the present time as to which is the procedure of choice. 相似文献

影响急性外份性硬脑膜外血肿疗效的相关因素分析(附484例报告) 总被引:2,自引:1,他引:1
目的探讨影响急性外伤性硬脑膜外血肿疗效的相关因素。方法对1994年5月至2004年5月收治的484例外伤性硬脑膜外血肿患者的临床资料进行回顾性分析。结果无脑疝症状者手术死亡率7.7%,有脑疝症状者死亡率21.3%。手术距脑疝发生时间<1h死亡率8.2%,1~2h死亡率40.0%,>2h死亡率72.2%。结论影响外伤性硬脑膜外血肿疗效的相关因素较多,除脑疝形成及手术距脑疝发生的时间外,创伤性低血压、合并脑损伤的程度、呼吸功能不全、大面积脑梗塞、血糖与血浆渗透压升高及肝功能异常等均对患者预后有重要影响。 相似文献

Parapubic hernia: case report and review of the literature 总被引:1,自引:0,他引:1
Parapubic hernia is considered rare, with 18 hernias described in five articles published since 1971. The hernia results
from iatrogenically or traumatically detached rectus abdominis muscles at the pubic bone and presents a therapeutic challenge
because there is no strong aponeurotic anchoring structure in the defect's caudal aspect. We describe a patient with a large
parapubic hernia repaired by a combined preperitoneal and onlay prosthetic method. This report adds another dimension to the
prosthetic repair options in parapubic hernias and illustrates the effectiveness of the tension-free repair principle in their
definitive management.

Before surgical intervention in the femoral area, doctors should be mindful of two situations in which surgery is not indicated
and, in fact, may cause harm.

A 78-year-old woman is described who presented with a diaphragmatic hernia through the foramen of Morgagni. A definitive
diagnosis was confirmed by a sagittal view on magnetic resonance imaging prior to surgery. The hernia was repaired laparoscopically
under an abdominal wall lifting technique without pneumoperitoneum, and her symptoms completely resolved postoperatively with
no evidence of recurrence. The laparoscopic repair was considered a suitable and safe procedure for the treatment of a Morgagni
hernia.

The role of endoscopic extraperitoneal herniorrhaphy (EEPH) in the management of giant scrotal hernias has not been well
defined, and the technical details relating to operations on such hernias have not been described. We present our experience
with 17 patients undergoing repair of giant scrotal hernias. Foley catheter bladder decompression was routinely employed.
The Retzius space was developed early in the procedure and hernia sac contents were reduced in all cases. The inferior epigastric
vessels were likewise divided in all patients. The average operative time was 76 min and all patients were discharged home
the same day. There have been no recurrences on follow-up. There was no mortality, and morbidity was limited to seroma formation
in two patients. We conclude that with certain technical modifications, EEPH can be safely employed for the treatment of giant
scrotal hernias.

Summary The authors report their experience of laparoscopic repair of large paraoesophageal hernias (POH). From February 1994 to January
1997, nine patients with a large POH containing at least 50% of the stomach have been treated laparoscopically. The surgical
procedure included reduction of the herniated stomach, closure of the hiatal orifice, and construction of a circular fundoplication.
There was no conversion into open surgery. One case of postoperative atelectasis was seen (morbidity: 12.5%). Postoperative
X-Ray demonstrated the restoration of a normal anatomical arrangements as well as an effective anti-reflux fundoplication.
Laparoscopy makes it possible to safely and efficiently repair large POHs with an acceptable morbidity. However, this type
of operation requires a good training in laparoscopic surgery. 相似文献

A patient developed a huge diaphragmatic hernia following laparoscopic gastric banding. Almost the entire stomach was incarcerated within the left chest. Segmental necrosis of the greater curvature of the stomach necessitated partial gastrectomy. The postoperative course was uneventful. The etiology, diagnosis and treatment of this previously undescribed complication of laparoscopic gastric banding are addressed in relation to the present case. 相似文献
