急诊显微修复15例手部皮肤逆行撕脱伤

目的报道采用显微外科修复方法急诊处理手部皮肤逆行撕脱伤。方法2003年9月--2006年7月,我们应用显微外科吻合技术及其相关方法处理15例手部皮肤逆行撕脱伤。结果15例全部成活,术后3～28个月随访,外形与感觉等功能恢复较为满意。结论采用显微外科修复方法处理手部皮肤逆行撕脱伤,可最大限度的恢复手部功能和外形,是目前较为理想的治疗方法。     

骨髓间充质干细胞分化为皮肤附属器细胞的初步实验研究

目的探讨骨髓间充质干细胞(marrowmesenchymalstemcells,MSCs)分化为创面皮肤附属器细胞的可能性,及其参与创面修复的可能机制。方法无菌条件下取Wistar大鼠股骨骨髓细胞,密度梯度离心分离、纯化MSCs,体外培养扩增后,用BrdU标记细胞。另于同种雄性Wistar大鼠背部正中,制备1cm×1cm全厚皮肤缺损创面模型,将BrdU标记的1×106/mlMSCs从阴茎静脉输注,术后第3天与第7天切取创面组织,行BrdU免疫组织化学单染色,以及BrdU和广谱角蛋白免疫组织化学双染色。结果BrdU阳性细胞出现在创面皮下组织、皮脂腺、毛囊和骨髓腔中。免疫组织化学双染色结果显示,皮脂腺和毛囊有BrdU阳性细胞,同时表达广谱角蛋白。结论创面愈合过程中,MSCs归巢并参与创面修复;在实验性全身皮肤缺损创面微环境下,MSCs可分化为皮肤附属器细胞。     

Is herniography useful?

Herniography has been used for 25 years in the diagnosis of occult herniation but has not gained widespread acceptance in the UK, despite studies confirming its high sensitivity and specificity for occult hernias and an excellent record of safety and patient acceptability. The traditional approach in the UK to suspected occult groin herniation has been surgical exploration. This study examined the use of herniography in a single district general hospital to assess its impact in limiting unnecessary groin explorations and allowing discharge of patients without hernias. The case notes of 90 successive patients referred for herniography by the department of general surgery in a single UK district general hospital over an 18-month period were reviewed. Eighty-seven completed examinations were analysed in which 23 hernias were diagnosed in 20 patients. Thirteen patients have undergone hernia repair with resolution of symptoms. There were no false positive examinations, although two inguinal hernias were incorrectly diagnosed radiologically as femoral hernias; there were two false negative examinations where additional hernias were found at laparoscopic repair. There were no reported complications. Twenty-four patients were discharged directly from the surgical clinic after a negative herniogram. Thirty patients were referred to other specialities. No patient had undergone groin exploration after a negative herniogram. Herniography is a useful tool in assessing obscure groin pain and potential occult herniation. It can reliably rule out the presence of a hernia and avoid the need for surgical exploration. Many patients with a negative herniogram can be reassured and discharged, whilst others may be referred on to other specialities safe in the knowledge that an occult hernia has been excluded.     

腹腔镜下切口疝补片修补术的临床应用

目的 探讨腹腔镜下腹壁切口疝修补术的手术方法、安全性等问题。方法对2004年3月至2006年5月79例行腹腔镜下补片修补术治疗腹壁切口疝病人的临床资料进行分析。结果 78例（98．7％）手术成功，1例因腹腔内广泛粘连而中转开放修补。平均手术时间为88min，平均术后住院4．6d，18例（22．8％）病人术中发现有1个以上的隐匿性缺损。术后并发症：术后短期内修补区腹壁明显疼痛58例（73．4％）。腹壁缝合点较长时间疼痛6例（7．6％），浆液肿14例（17．7％），无手术死亡，1例术后出现肠瘘，经保守治疗好转，1例腰部切口疝的病人术后复发。结论 多数病人腹壁切口疝可以经腹腔镜行粘连松解及补片修补术，并可在术中发现其他隐性缺损，手术安全性较高。对腹腔内广泛粘连而影响操作器械进入及粘连分离者，应及时中转开腹手术。     

Acute Leukemia in an Infant with Marfan's Syndrome: A Case Report

We describe a familial case of Marfan's syndrome with associated intrathoracic stomach detected during the neonatal period. The patient developed a primitive leukemia at 3 months of age. Acute leukemia in a patient with Marfan's syndrome has not previously been reported.     

Day surgery for laparoscopic repair of abdominal wall hernias

Laparoscopic repair of abdominal wall hernias is still a controversial and nongeneralized therapeutic option. The aim of this paper is to evaluate the results of laparoscopic surgery on abdominal wall hernias at a day-surgery unit and to describe our procedure protocol. Prospective analysis of 300 patients undergoing laparoscopic surgery for abdominal wall hernias was conducted: 260 preperitoneal and 40 intraperitoneal. The patients' clinical features, hernia type, intraoperative and postoperative complications, and follow-up are studied for both types of surgery. All the patients receiving surgery with extraperitoneal laparoscopy were completed as a day-surgical procedure with a rate of conversion to open surgery of 2.3%. Twelve (30%) of the 40 patients operated on for ventral hernias using intraperitoneal laparoscopy required hospitalization: five for perioperative complications and seven for pain (16%). There was no case of infection or mesh rejection. The recurrence rates were 0.78% (two cases) for the inguinal hernias and 2.5% (one case) for the ventral hernias. In conclusion, laparoscopic repair of abdominal wall hernias in a day-surgery setting is an efficient alternative to open surgery. Electronic Publication
