单蒂横行腹直肌肌皮瓣乳房再造中Ⅳ区皮瓣的取舍

目的探讨单蒂横行腹直肌肌皮瓣乳房再造术中Ⅳ区皮瓣的取舍。方法通过16例实施单蒂横行腹直肌肌皮瓣乳房再造术，术中观察皮瓣的皮色、断面出血颜色，并利用近红外血氧监测仪测定皮瓣各区的组织血氧饱和度，决定Ⅳ区皮瓣的取舍。术后观察指标包括术后并发症及美学效果。结果16例中5例Ⅳ皮瓣的肤色正常、断面出血呈鲜红色而非暗红色、组织血氧饱和度不低于Ⅲ区组织血氧饱和度的95％。在接受了保留Ⅳ区皮瓣的单蒂横行腹直肌肌皮瓣乳房再造术后，再造乳房全部成活，无严重术后并发症，患者对再造乳房均很满意。结论近红外血氧无创检测有助于决定Ⅳ区皮瓣的取舍。有选择地实施保留Ⅳ区皮瓣的单蒂横行腹直肌肌皮瓣乳房再造术，可用于大面积胸壁缺损或乳腺尾叶的修复重建。     

Rectus “wrap around” flap for salvage of an infected ascending aortic graft

An application of the rectus abdominis muscle flap to salvage an infected prosthetic graft of the ascending thoracic aorta is presented. The length of this flap along with its width and thickness allows it to be wrapped around prosthetic grafts of the ascending aorta in a spiral fashion. This rectus muscle wrap around flap method is straightforward involving the use of one muscle rather than multiple muscles. The abdominal cavity is not opened as with the use of omentum. The procedure can be accomplished in a short time which is important in the critically ill patient.     

Neuroblastoma-like epidural localization in non-Hodgkin's lymphoma

Summary We report a case of non-Hodgkin's lymphoma with CNS involvement confined to the epidural space causing cranial suture diastasis. Cerebrospinal fluid and bone marrow were normal. Two cases only of cranial epidural lymphoma have been reported in the literature; in both cases, the leptomeninges were also involved but without suture diastasis.

Functional combination of tapering profiles and overlapping arrangements in nonspanning skeletal muscle fibers terminating intrafascicularly

Using digital image analysis and several anatomical methods, morphometric analysis of nonspanning fibers which had tapering profiles at their intrafascicular termination sites and represented overlapping arrangements within the fiber fascicles was performed in the rat rectus abdominis. Special emphasis was focused on dimensional relationships occurring between overlapping portions and tapering segments and sarcomere lengths in non- and overlapping portions. Nonspanning fibers were found to overlap each other for more than 40% of their length. In length, their overlapping portions generally corresponded to their tapering segments, which were also greater than 40% of the fiber length. In addition, despite the presence of overlapping linkages, nonspanning fibers maintained a fairly uniform length irrespective of their overlapping and non-overlapping portions. Overlapping linkages in fibers without tapering profiles have a larger cross-sectional area in the overlapping portion than in the non-overlapping one, resulting in a phenomenon which will cause different sarcomere lengths between the two portions during fiber stretching. The present results suggest that tapering profiles in the overlapping portion ensure uniform sarcomere lengths within nonspanning fibers, thereby providing mechanical stability in each fiber. © 1993 Wiley-Liss, Inc.     

内镜下全腹膜外Sublay修补在腹壁疝中的应用

目的评价腹壁疝内镜下全腹膜外Sublay(TES)手术的效果并总结经验。方法回顾性总结国内10所医院自2016年3月至2019年7月115例腹壁疝内镜下TES手术的患者资料。分析患者情况、疝的特点、手术经过和结果。结果115例计划实施TES的患者中,因严重腹膜破损中转为IPOM修补患者1例,其余均成功手术。可以缝合缺损患者108例(94.74%),需要永久补片固定患者15例(13.16%)。放置引流患者76例(66.67%),中位手术时间为144 min,术中无严重并发症发生。随访时间3~45个月,总并发症发生率为20例(17.54%),其中出现血清肿患者5例(4.38%)。绝大多数患者术后仅出现轻微疼痛,未出现慢性疼痛。结论在腹壁疝的治疗中,对熟悉腹壁解剖的外科医师而言,TES是一种有效、安全的修复手段。在熟悉手术的基础上适应症可逐步拓展。     

An anterior extraperitoneal incision for donor nephrectomy that spares the rectus abdominis muscle and anterior abdominal wall nerves

PURPOSE: To perform open donor nephrectomy with the least amount of body alteration and complication, a short extraperitoneal incision was developed that preserves the ipsilateral rectus abdominis muscle and abdominal branches of the intercostal nerves. MATERIALS AND METHODS: Donor nephrectomy using the new incision was performed in 11 consecutive patients. RESULTS: Morphine was required for pain relief for 1 to 3 days (mean 1.8), patients tolerated diet at 1 to 4 days (mean 2.2) and postoperative stay was 2 to 5 days (mean 3.5). Complications were minimal, consisting of postoperative fever 1 day in duration. A viable kidney was provided for transplantation in each case. CONCLUSIONS: The extraperitoneal, rectus abdominis muscle and nerve sparing incision resulted in a short course of pain medication, early diet toleration and a short hospital stay.     

Rectus abdominis myocutaneous flap in radical oncopelvic surgery: A safe and useful procedure

AIMS: The aim of this retrospective study was to evaluate the usefulness of rectus abdominis myocutaneous (RAM) flaps to treat locally advanced pelvic gynaecological or digestive tumours. METHODS: We reviewed 46 patients, who received RAM flaps after radical oncopelvic surgery, including: (a) total vaginal reconstruction (TVR); (b) partial vaginal reconstruction (PVR); (c) perineal reconstruction (PR). RESULTS: Between 1989 and 1998, 46 patients underwent pelvi-perineal reconstruction with RAM flaps after radical pelvic surgery for carcinoma of the cervix (n=22), anal carcinoma (n=11), rectal carcinoma (n=7), or other pelvic tumours types (n=6). There were two post-operative deaths. Overall surgical morbidity was 45, 6% (n=21). Specific morbidity of the RAM flap was 21, 7% (n=10). Global re-intervention rate was 13% (n=6). CONCLUSION: Rectus abdominis myocutaneous flap in radical oncopelvic surgery is useful for vaginal or perineal reconstruction and prevention of pelvic collections after extended resections with a low rate of associated morbidity.
