303. Orientierungshilfen in der diagnostischen und operativen Schulterarthroskopie

Zusammenfassung Zu Beginn des Videofilms wird die Problematik der Rectumcarcinomdiagnostik mit genauer Bestimmung der Wandinfiltration dargestellt. Als zusätzliches diagnostisches Verfahren wird sodann die endorectale Sonographie und deren Prinzip erläutert. An einer Falldarstellung (Patient mit ulcerierendem Rectumcarcinom und Rectumpolypen) wird die sonographische Methode im Vergleich mit der Rectoskopie und weiteren bildgebenden Verfahren sowie dem Operationspräparat und dem histologischen Schnitt verglichen. Eine weitere Anwendungsmöglichkeit der endorectalen Sonographie liegt in der Verlaufskontrolle operierter Patienten mit Rectumcarcinom. Dies wird an einer weiteren Falldarstellune erläutert.     

胰腺囊腺瘤和囊腺癌的诊断及外科治疗

目的探讨胰腺囊腺瘤和囊腺癌的诊断和治疗方法。方法对2000年6月～2005年6月复旦大学附属中山医院收治的24例胰腺囊腺瘤和囊腺癌的临床资料进行回顾性分析。结果胰腺囊腺瘤和囊腺癌无特征性临床表现。B超和CT对胰腺囊性肿瘤的诊断正确率分别达到88%(21/24)和92%(22/24),但不能准确区分其类型。3例浆液性囊腺瘤未行手术治疗;21例手术者中,行胰十二指肠切除术9例,远端胰腺切除术8例,胰腺节段切除术1例,肿瘤摘除术3例,胰瘘是主要的并发症。本组患者均获随访,3例未手术者肿瘤无增大,1例囊腺癌因复发转移于术后11个月死亡,其余均健在,术后无复发。结论B超和CT是胰腺囊性肿瘤主要的影像学检查方法。黏液性囊性肿瘤以及伴有症状的浆液性囊腺瘤需手术治疗。胰腺囊腺瘤手术切除后可获治愈,囊腺癌术后疗效也较满意。     

36例胰腺浆液性囊腺瘤的临床分析

目的：探讨胰腺浆液性囊腺瘤的诊断和治疗。方法：对1998年6月至2006年9月瑞金医院收治的36例病理诊断为胰腺浆液性囊腺瘤的临床资料进行回顾性分析。结果：胰腺浆液性囊腺瘤好发于中老年女性,多见于胰腺头颈部,无特征性临床表现。B超和CT诊断囊性肿瘤的正确率分别为69%（25/36）和94%（34/36）。CT对于囊腺瘤的诊断正确率为80%（29/36）,对浆液性囊腺瘤的诊断正确率为61%（22/36）。在不能排除或考虑实性假乳头状瘤的病人中MRI对于囊腺瘤的诊断正确率80%（4/5）。本组35例行手术治疗,其中7例行胰十二指肠切除;11例行胰腺节段切除;12例行胰体尾切除;5例行局部切除,1例行剖腹探查活组织检查。10例术后出现并发症,包括胰瘘、内出血、幽门梗阻、胰腺假性囊肿合并肠瘘病人及不同程度的胸腔积液。1例因内出血死亡。本组3例失访,32例获随访,除2例因其它疾病死亡,其余均健在,术后无复发。结论：CT和MRI,结合肿瘤学指标和临床病理特征可大大提高浆液性囊腺瘤的术前诊断率。浆液性囊腺瘤是一种良性的肿瘤,但手术治疗并发症较多。大多数浆液性囊腺瘤可考虑随访;有症状的胰腺浆液性囊腺瘤,或与黏液性囊性肿瘤不能鉴别者,应手术治疗。     

107例胃肠间质瘤的病理学分析及临床诊治

目的总结胃肠间质瘤(GIST)的临床病理和免疫组织化学(免疫组化)特征,并评价预后。方法对1996年4月至2005年10月收治的107例GIST患者的临床资料进行回顾性分析。结果107例GIST病例中,73例(68.2%)为胃间质瘤,其他为小肠、结肠和系膜、网膜及后腹膜间质瘤;肿瘤直径0.7～20cm。CD117和vimentin阳性率100%,CD34阳性率83.2%。107例患者均接受手术治疗,联合脏器切除14例次。总随访率83.2%,平均随访24.5个月。14例(13.1%)发现复发或转移,其中4例为GIST中度恶性风险者。10例为高度恶性风险者;死亡4例。结论GIST的确诊主要依靠病理及免疫组化,CD117是诊断GIST的重要标记物,手术完整切除肿瘤效果满意,恶性GIST宜行较大范围的切除术。必要时须行联合脏器切除。

Elective laparoscopic-assisted colectomy for sigmoid diverticulitis.

OBJECTIVES: The aim of this study was to evaluate the safety and effectiveness of laparoscopic-assisted sigmoid colectomy for diverticulitis and to assess its postoperative advantages. METHODS: From 1999 to 2001, 5 patients were selectively operated on with a laparoscopic-assisted procedure for uncomplicated sigmoid diverticulitis. In the preceding period (September 1997 through December 1998), 4 patients underwent open procedures for the same pathology. The surgical indication with the same criteria was restrictive: at least 2 acute episodes had occurred that were treated with hospital admission and that were separated by an adequate period (2 months) of medical therapy. RESULTS: No conversions of laparoscopy to an open procedure were necessary. Age, sex, weight, morbidity, and mortality were similar between the 2 groups. Operative time was 180 minutes for laparoscopy and 120 minutes for laparotomy. Postoperative resumption of peristalsis was 24 hours versus 4 days, resumption of alimentation was on the second postoperative day versus the fifth postoperative day, and hospital stay was 7 days versus 12 days for laparoscopy and laparotomy, respectively. CONCLUSION: This study shows the feasibility and the advantages of elective laparoscopic-assisted colonic resection for uncomplicated sigmoid diverticulitis. The advantages of the laparoscopic approach are the lower need for analgesics and the more precocious ambulation, canalization, resumption of alimentation, and the shorter hospital stay.     

踝关节骨折54例手术治疗分析

Greater curve approach for laparoscopic gastric bypass: total stapler gastrojejunostomy

BACKGROUND: Gastric bypass is an established bariatric procedure that has undergone multiple modifications to improve its effectiveness. The side-to-side stapled technique is well recognized, but closure of the gastrotomy/enterotomy by the stapler can potentially narrow the Roux limb. Because of this, many surgeons will hand suture the closure of the gastrotomy/enterotomy. To obviate this difficulty, we inserted the linear stapler from the stomach's greater curvature, using a double-stapled anastomosis that minimized the need for hand suturing. METHODS: We performed a retrospective analysis of 307 patients undergoing this technique for laparoscopic gastric bypass. The weight loss and 30-day morbidity and mortality were tabulated and compared with those in other published series. RESULTS: Of the 307 patients, none died postoperatively. The overall 30-day morbidity rate was 15%. Two leaks from the gastrojejunostomy and 2 from the jejunojejunostomy (1.2%) developed. The mean percentage of excess weight loss was 34% at 3 months, 52% at 6 months, 73% at 1 year, 71% at 2 years, and 69% at 3 years. CONCLUSION: The greater curve approach avoids Roux limb obstruction, minimizes the need for hand suturing, and uses standard trocar incisions. Our short-term follow-up results are similar to those of series of other techniques.     

用颈长肌重建预防颈前路植骨块滑脱的临床应用

目的:探讨颈长肌重建对颈椎前路手术并发症的预防作用。方法:将颈椎病确诊病例分为实验组126例和对照组128例。对照组病例采用颈椎前路减压、植骨和/或钢板内固定术。实验组病例在完成上述手术之后,利用两种方法使颈长肌瓣重建植骨块或钢板表面。两组病例术后均获得随访,并将两组术后疗效及手术并发症的随访结果进行统计学分析。结果:两组术后随访0.5~6年,平均3.5年。根据Odom评分标准,对两组术后临床疗效进行评价,经统计学分析,P>0.05,说明两组术后疗效无明显差异。而对两组病例术后并发症的统计学分析,P<0.05,两组有统计学意义,表明颈长肌重建可以减少术后并发症的发生。结论:颈长肌重建是预防颈椎前路手术并发症的一种有效方法。     

Laparoscopic Medial-to-lateral Colon Dissection: How and Why

Laparoscopic colectomy is a difficult procedure with a long learning curve. We describe in this study our technique for right- and left-sided laparoscopic medial-to-lateral colectomy. The medial approach involves division of the vascular pedicle first, followed by mobilization of the mesentery toward the abdominal wall, and finally freeing of the colon along the white line of Toldt. This approach allows immediate identification of the plane between the mesocolon and the retroperitoneum and renders the dissection fast and safe. Our series of 50 consecutive laparoscopic colectomies supports this concept. We believe that surgeons familiar with this technique will have an important tool in their armamentarium to circumvent some of the challenges of laparoscopic colectomy.
