Lymphatic Drainage of the Peritoneal Space: A Pattern Dependent on Bowel Lymphatics

Background Understanding lymph drainage patterns of the peritoneum could assist in staging and treatment of gastrointestinal and ovarian malignancies. Sentinel lymph nodes (SLNs) have been identified for solid organs and the pleural space. Our purpose was to determine whether the peritoneal space has a predictable lymph node drainage pattern. Methods Rats received intraperitoneal injections of near-infrared (NIR) fluorescent tracers: namely, quantum dots (designed for retention in SLNs) or human serum albumin conjugated with IRDye800 (HSA800; designed for lymphatic flow beyond the SLN). A custom imaging system detected NIR fluorescence at 10 and 20 minutes and 1, 4, and 24 hours after injection. To determine the contribution of viscera to peritoneal lymphatic flow, additional cohorts received bowel resection before NIR tracer injection. Associations with appropriate controls were assessed with the χ² test. Results Quantum dots drained to the celiac, superior mesenteric, and periportal lymph node groups. HSA800 drained to these same groups at early time points but continued flowing to the mediastinal lymph nodes via the thoracic duct. After bowel resection, both tracers were found in the thoracic, not abdominal, lymph node groups. Additionally, HSA800 was no longer found in the thoracic duct but in the anterior chest wall and diaphragmatic lymphatics. Conclusions The peritoneal space drains to the celiac, superior mesenteric, and periportal lymph node groups first. Lymph continues via the thoracic duct to the mediastinal lymph nodes. Bowel lymphatics are a key determinant of peritoneal lymph flow, because bowel resection shifts lymph flow directly to the intrathoracic lymph nodes via chest wall lymphatics.

Retrorectal epidermoid cyst in an elderly woman: Report of a case

An epidermoid cyst is a common occurrence in the skin. Such a cyst occurring in the retrorectal space, however, is extremely rare. We herein present a case of retrorectal epidermal cyst in a 67-year-old Japanese woman. She reported no symptoms and a perirectal mass behind the lower rectum was accidentally detected by computed tomography (CT). Contrast CT and magnetic resonance imaging revealed a cystic mass (76 x 70 x 63 mm) with a slightly enhanced thin wall which was attached to the lower rectum. The patient underwent surgery via a posterior approach. The mass was exposed after an excision of subcutaneous fat and was firmly adhered to the anal sphincter muscle. The cystic mass was completely removed without a proctectomy. Histologically, the cyst was diagnosed to be an epidermoid cyst. The postoperative course was uneventful, and the patient was discharged on postoperative day 9. A diagnosis of retrorectal cystic tumor is difficult, and a complete resection is necessary for the treatment of such tumors.

腹膜后间隙出血的诊治

目的总结腹膜后间隙出血的诊治经验。方法回顾性分析1995年至2005年收治109例腹膜后出血患者资料。男70例,女39例,年龄6～69岁,平均33岁。外伤性89例,自发性20例。患者均因外伤后或自发性突然腰腹痛、血尿或休克表现就诊。109例经B超检查,104例行CT检查,7例急诊腹膜后探查术。109例患者中肾脏破裂出血101例（92．7％）、肾外病变破裂出血8例（7．3％）。外伤性89例中肾脏破裂84（94．4％）、腹膜后肾外病变破裂出血5例（5．6％）,自发性20例中肾脏破裂出血17例（85．0％）、肾外病变出血3例（15．0％）。肾外病变主要有嗜铬细胞瘤、平滑肌瘤、平滑肌肉瘤、神经鞘瘤、淋巴肉瘤等。结果109例患者中腹膜后手术26例,肾切除术8例、肾癌根治术8例、腹膜后肿瘤切除7例、肾切除加平滑肌瘤切除1例、肾包膜切开引液术2例。保守治疗83例,采取卧床休息、补液、止血、抗感染、输血、镇静治疗。10例恶性肿瘤患者中1例淋巴肉瘤患者术后10个月死亡,1例平滑肌肉瘤患者9个月死亡,8例肾癌患者中2例于术后18、20个月死于全身衰竭,余6例2年内未复发。其他99例患者痊愈出院后随访6个月,B超、CT检查未发现腹膜后病变复发。结论腹膜后出血可由肾脏或肾外病变破裂所致,B超能准确检查出腹膜后血肿,CT对辨别出血部位、范围、程度、原因及检出肿瘤有重要价值。对危及生命的腹膜后大出血应急诊手术,病情稳定者可先保守治疗,明确诊断后采取相应的治疗方式。
