Subcapital callus resection for slipped capital femoral epiphysis

Surgical Principles The lateral approach is routinely combined with an osteotomy of the greater trochanter. We resect the newly formed callus located at the anterior, posterior and caudal aspect of the femoral neck distal to the epiphysis. No shortening of the femoral neck results from this procedure. One can safely avoid a vascular injury by performing a careful dissection, since the posteriorly reflected articular capsule containing the nutrient vessels to the head is detached from the femoral neck like a banana peel. The resection manoeuvre is performed next to the physeal plate of the slipped epiphysis. After callus resection, reduction of the femoral head by longitudinal traction and internal rotation of the limb is easy. The aim is complete correction of the slippage. When there is excess physeal cartilage, we resect it with a curette and then the head is fixed using 2 screws. Revised Version from: Operat. Orthop. Traumatol. 4 (1992), 77–85 (German Edition).     

Is the circumferential resection margin a predictor of local recurrence after preoperative radiotherapy and optimal surgery for rectal carcinoma?

OBJECTIVE: Circumferential resection margin (CRM) involvement has been correlated with a high risk of developing local recurrence. The aim of this study was to examine the prognostic significance of the CRM involvement after curative resection of rectal cancer in patients treated with preoperative radiotherapy and postoperative chemotherapy where indicated. METHOD: All patients with rectal cancer treated in a regional central unit from 1996 to 2004 were identified. A surgical resection was performed on 257 patients, and in 229 of these this was assessed as potentially curative. The CRM was examined in all patients. A CRM of < or = 1 mm was considered positive. RESULTS: A positive margin was seen in 19 (8%) patients. At a median follow up of 40 months, only four (1.7%) patients had developed local recurrence, one of whom had a positive CRM. In the four patients the tumour was 5 cm or less from the anal verge. There were no significant differences regarding local recurrence and survival between CRM positive and negative tumours. CONCLUSION: Rectal cancer managed by combined radiochemotherapy and surgery resulted in a low positive CRM rate and a low local recurrence rate. An involved CRM was not a predictor of local recurrence.     

Liver resection without hilus preparation and with selective intrahepatic hilus stapling for benign tumors and liver metastasis

Background Nowadays, liver resection is a routine operative procedure in surgical centers, and strategies must be aimed at avoiding additional risk factors. Extrahepatic isolation of portal vein, hepatic artery and hepatic duct, as well as lymphadenectomy of the liver hilum are generally accepted steps of liver resection, even for metastatic and benign indications. Our primary aim was to analyze the feasibility, blood loss, blood transfusion requirements, incidence of complications, and outcome using the approach for intrahepatic devascularization leaving the extrahepatic hilus untouched. Materials and methods Thirty-eight consecutive patients with resection for metastases and benign liver tumors were selected. After hilar examination, the extrahepatic structures remain intact, and during parenchyma dissection, the whole right or left or the appropriate bi-segmental pedicle is isolated intrahepatically and then transected using a stapler device. Results The used technique was feasible in all cases, and no intra- or postoperative surgical complications were observed. To date, no tumor recurrence was found in the hilum during the follow-up period. Conclusion The intrahepatic pedicle stapling technique appears to be feasible and safe in liver resection. Hilar dissection can, thus, be avoided in liver metastasis and benign liver tumors.

腹腔镜微创技术施行直肠癌腹会阴联合切除手术的体会

目的:总结腹腔镜微创技术施行腹会阴联合切除术(abdom inal pelvic resection,APR)治疗低位直肠癌的手术体会。方法:2003年1月至2006年12月,我院为17例低位直肠癌患者行腹腔镜微创APR根治术。其中男10例,女7例,45~82岁,平均72岁。腹部手术在腹腔镜下完成,会阴部手术按常规手术进行。结果:17例中14例(82.4%)采用完全腹腔镜术式,3例(17.6%)采用腹腔镜辅助术式。手术中均未行盆底腹膜关闭和结肠造口旁间隙关闭。平均手术时间为(166.2±42.7)m in,全组无手术死亡病例。术后早期并发症有会阴部切口感染2例(11.8%),不全性肠梗阻1例(5.9%)。术后随访2~48个月,平均26个月,最长无瘤生存期48个月,造口旁疝1例(5.9%),远处转移1例(5.9%),无局部复发,无戳口和切口肿瘤种植以及肠梗阻发生。结论:腹腔镜微创技术用于APR手术具有患者创伤小的优势;术中造成的系膜裂孔和盆底腹膜均无缝合关闭的必要,但结肠造口必须严密缝合腹膜防止造口旁疝形成;会阴部手术必须严格无菌操作预防感染。腹腔镜微创技术是APR手术的较好方式。     

Sentinel Bleeding After Pancreaticoduodenectomy: A Disregarded Sign

Introduction Delayed massive hemorrhage induced by pancreatic fistula after pancreaticoduodenectomy is a rare but life-threatening complication. The purpose of this study was to analyze the clinical course of patients with late hemorrhage, with or without sentinel bleeding, to better define treatment options in the future. Material and Methods From April 1998 to December 2006, 189 pancreaticoduodenectomies were performed. Eleven patients, including two patients referred from other hospitals, were treated with delayed massive hemorrhage occurring 5 days or more after pancreaticoduodenectomy. Sentinel bleeding was defined as minor blood loss via surgical drains or the gastrointestinal tract with an asymptomatic interval until development of hemorrhagic shock. The clinical data of patients with bleeding episodes were analyzed retrospectively. Results Eight of the 11 patients had sentinel bleeding, and seven of them had it at least 6 h before acute deterioration. Seven out of 11 patients died, five out of eight with sentinel bleeding. No differences could be detected between patients with or without sentinel bleeding before delayed massive hemorrhage. The only difference found was that non-surviving patients were significantly older than surviving patients. Delayed massive hemorrhage is a common cause of death after pancreaticoduodenostomy complicated by pancreatic fistula formation. The observation of sentinel bleeding should lead to emergency angiography and dependent from the result to emergency relaparotomy to increase the likelihood of survival.     

ENDOSCOPIC MUCOSAL RESECTION AND SUBMUCOSAL DISSECTION METHOD FOR LARGE COLORECTAL TUMORS

The goal of endoscopic mucosal resection (EMR) is to allow the endoscopist to obtain tissue or resect lesions not previously amenable to standard biopsy or excisional techniques and to remove malignant lesions without open surgery. In this article, we describe the results of conventional EMR and EMR using an insulation‐tipped (IT) electrosurgical knife (submucosal dissection method) for large colorectal mucosal neoplasms and discuss the problems and future prospects of these procedures. At present, conventional EMR is much more feasible than EMR using IT‐knife from the perspectives of time, money, complication, and organ preservation. However, larger lesions tend to be resected in a piecemeal fashion; and it is difficult to confirm whether EMR has been complete. For accurate histopathological assessment of the resected specimen en bloc EMR is desirable although further experience is needed to establish its safety and efficacy. Further improvements of in EMR with special knife techniques are required to simply and safely remove large colorectal neoplasms.     

结直肠癌肝转移的外科手术治疗

目的评价手术治疗对结直肠癌肝转移病人生存率的影响。方法回顾分析2000年1月1日至2004年12月31日复旦大学附属中山医院收治的363例结直肠癌肝转移病人，其中91例为手术病例，评价手术治疗对生存率的影响。结果160例同时性肝转移病人中手术切除肝转移灶22例（13．8％），203例延时性肝转移病人中手术切除肝转移灶69例（34．0％），两者相比差异具有统计学意义（P〈0．000）。同时性肝转移组手术死亡率（4．5％，1／22）高于延时性肝转移组（2．8％，2／69），两者相比差异有统计学意义（P〈0．05）。以2005年6月31日为随访终点，91例病人随访率100％，手术病人中同时性肝转移组1、3、5年生存率和中位生存时间与延时性肝转移组相似（P〉0．05），但术后复发率较高（36．4％vs21．7％，P=0．03）。363例病人中有36例具有手术指征而未手术病例，其1、3、5年生存率分别为47．9％、5．34％和0，明显低于91例手术病例（80．5％、33．0％和22．7％），（P=0．0034）。应用COX比例风险模型，对所有91例手术病人影响生存的因素进行多因素风险分析，得出手术切缘达1cm（β=-0．8351，P=0．0363）和复发后再次手术（β=-0．9428，P=0．0411）是生存的保护性因素，而术后复发（β=0．6471，P=0．0226）是生存的危险因素。结论手术治疗是结直肠癌肝转移的首选治疗措施，可以明显提高病人的术后生存。
