Surgery of the spleen

The spleen is a solid organ located beneath the left hemidiaphragm. Indications for surgical resection include trauma (blunt or penetrating), haematological diseases, abscesses, hydatid disease, oncological resection or immunosuppression. Surgical approaches include open, laparoscopic and, more recently, robotic; the complications of operative intervention will also be discussed. In patients with an absent spleen there is a significant increased risk of developing overwhelming post-splenectomy infection (OPSI). It is therefore essential to protect patients from infection due to encapsulated organisms through vaccination. This requires a combination of vaccinations, antibiotic prophylaxis and good education.     

脾大部切除加断流术治疗小儿门静脉高压症(附16例临床分析)

目的探讨脾大部切除加断流术治疗小儿门静脉高压症的临床疗效。方法对16例确诊为门静脉高压症的患儿行脾大部切除加断流术。随访患儿恢复情况。结果16例患儿手术顺利,恢复良好,无死亡病例。无再发消化道出血、脾功能亢进表现,无脾切除术后凶险感染出现。结论保留脾脏的脾大部切除加断流术是治疗小儿门静脉高压症一种较好的手术方法。     

外伤性延迟性脾破裂的诊断和治疗（附21例报告）

目的探讨外伤性延迟性脾破裂的发病规律、临床特点、诊断和治疗方法。方法结合国内外资料及本组病例进行回顾性分析。结果明确诊断16例，误诊为肝破裂2例，宫外孕破裂2例，脾肿瘤1例。21例均手术治疗，行脾切除14例，其中保留副脾2例；脾切除加自体脾组织网膜内移植术3例；脾缝合修补术3例；脾部分切除术1例。死亡1例，原因有就诊晚、失血性休克。结论本病由于腹腔内出血与受伤时间间隔长，容易误诊。诊断除依靠病史、临床表现外，应及时进行腹腔穿刺、B超及CT检查。治疗以脾切除为主，可根据病情、脾破裂的程度以及是否有合并伤等情况采取保脾手术。     

原发性脾脏恶性淋巴瘤21例的临床分析

目的 研究原发性脾脏恶性淋巴瘤（SPL）的临床和病理特征与治疗方法。方法 对1975-2000年收治的21例原发性脾脏恶性淋巴瘤患者的临床资料进行回顾性分析。结果 21例均行手术治疗，14例行COP或CHOP方案化疗，7例未行化疗，术后5年生存率分别为35．7％和28．6％。21例均为术后病理确诊，其中B细胞源性20例，T细胞源性1例。按Ahman脾恶性淋巴瘤临床分期，Ⅰ期9例，Ⅱ期7例，Ⅲ期5例，5年生存率分别为55．6％、42．9％、20％。结论 原发性脾脏恶性淋巴瘤的诊断主要依靠B超和CT，病期的早晚影响其预后，手术治疗联合化疗是本病的主要治疗方法。     

脾脏切除后暴发性感染6例临床分析

目的探讨脾切除术后暴发性感染的临床的特点。方法对6例OPSI患者的原发疾病、临床特点及其病原学进行分析。结果4例原发疾病属于造血系统疾病,1例脾功能亢进,1例外伤性脾破裂;所有病例均起病急促而凶猛、病情迅速恶化,于短期内出现休克及DIC;所有病例血细菌培养均阳性,3例为G 球菌,2例为G-杆菌,1例为G-杆菌合并霉菌感染;经强有力地抗感染治疗5例痊愈,1例死亡。结论OPSI病情凶险,死亡率高,尤其是血液病患者OPSI发生率较高,医生在行脾脏切除时应慎重。     

Laparoscopic splenectomy for isolated parenchymal splenic metastasis of ovarian cancer

Metastatic carcinoma of the spleen occurs in a setting of widespread malignant disease. Solitary parenchymal splenic metastasis of ovarian carcinoma is rare. We report a case of a 59-year-old woman who presented with an elevated serum CA125 level due to a solitary splenic metastasis after a long disease-free period. She was treated with laparoscopic splenectomy followed by chemotherapy. The literature contains 16 cases of solitary parenchymal splenic metastasis of ovarian carcinoma. Our case is the third case that was treated with laparoscopic splenectomy. We review the literature, and we focus on the laparoscopic approach in managing these cases.     

Laparoscopic management of a ruptured giant epidermoid splenic cyst.

BACKGROUND: Epidermoid splenic cysts are uncommon lesions of the spleen. They are known to become symptomatic as a consequence of enlargement, infection, or rupture, the latter being an exceedingly rare complication traditionally treated with open splenectomy. We herein report a unique case of a giant epidermoid splenic cyst that ruptured spontaneously and was successfully treated with the laparoscopic approach. CONCLUSION: Laparoscopic surgery may be considered an initial treatment option in cases of very large epidermoid cysts even when rupture occurs.     

外伤性脾切除术后中医证候及免疫功能的研究

目的:研究外伤性脾切除术后中医辨证与免疫功能变化的关系.方法:选择15例脾切除和15例非脾切除患者作为观察对象,以其症状、舌苔、脉象及免疫功能的测定作为观察指标,观察其中医辨证与免疫功能变化.结果:脾切除组在术后早期可出现脾胃虚弱的证候群,同时免疫功能测定补体C3、免疫球蛋白IgG、免疫球蛋白IgM的水平明显降低,与非脾切除组有显著性差异.结论:脾切除容易造成患者术后出现的脾胃虚弱症候群,并降低患者的免疫功能.     

Treatment options for primary splenic low‐grade non‐Hodgkin's lymphomas

The purpose of this comparative study was to evaluate the response of primary splenic low‐grade non‐Hodgkin's lymphomas (NHL) to chemotherapy, splenectomy, and chemotherapy combined with splenectomy in order to elaborate the optimum treatment modality. A total of 104 patients (age range: 15–82 years) with primary low‐grade B‐cell NHL of the spleen were comprised by our study. Stage IV disease was determined in 102 (98.1%) cases. Regarding the treatment modality, splenectomy was performed in 14 patients, early splenectomy and single‐agent chemotherapy in 15, early splenectomy and combined chemotherapy in 19, single‐agent chemotherapy in 23, and combined chemotherapy in 33. In the above‐mentioned order, complete remission rate was following: none, 40.0, 31.6, 21.8, and 18.2%. Partial remissions were achieved in 85.7, 46.7, 57.9, 30.4, and 69.7% of cases, respectively. The median remission duration turned out to be longer (74.5 months) in the group of patients with complete remissions attained by means of splenectomy and combined chemotherapy. Local relapses in the spleen developed in 19 (72.7%) patients treated with combined chemotherapy and in 9 (90.0%), who had undergone single‐agent chemotherapy. The 5‐year overall survival was 54.4% after splenectomy, 39.4% after single‐agent chemotherapy, and 37.1% after combined chemotherapy, being significantly higher (P < 0.05) after splenectomy and single‐agent chemotherapy (67.2%), and splenectomy followed by combined chemotherapy (64.7%). Early splenectomy combined with chemotherapy is the optimum treatment option for primary low‐grade NHL of the spleen because of the superiority in complete remission rate, remission duration, and in overall survival rate. Splenectomy leads to somatic compensation of patients, makes impossible local relapsing in the spleen, prevents continuous dissemination from the primary tumor site, and mostly corrects cytopenias, creating better conditions for chemotherapy.     

脾肾分流加联合断流术治疗门静脉高压症

目的：探讨提高肝硬化门静脉高压症疗效的术式。方法：采用脾肾分流加联合断流术即脾切除。脾肾分流,胃底、贲门周围血管离断,食道下段离断吻合术治疗门脉高压症患者20例。术中连续监测自由门静脉压力（FPP）的动态变化。术后随访12例。随访时间6-30个月。结果：术后死亡1例,随随例患者无1例再出血及发生肝性脑病。术后2个月行食道钡餐检查,食道静脉曲张消失或基本消失10例,明显好转2例。11例术前有腹水,其中2例术前大量腹水,10例术后2个月左右腹水消失,1例术前大量腹水者术后6个月腹水基本消失,术后6个月内彩色多普勒检查9例,均显示门静脉向肝血流,脾肾吻合通畅,无血栓形成,结论：脾肾分流加联合断流术治疗门脉高压症既保留了分流术和断流术二者的优点,又克服了二者的缺点,而且联合断流术使断流更加彻底。
