[The posterior interparietoperitoneal spaces or retroperitoneal spaces. 1: Normal topographic anatomy].

The posterior spaces between the wall and peritoneum or extraperitoneal spaces are located between the visceral retrocolic and retro-duodenopancreatic fascias anteriorly and the parietalis fascia posteriorly. They were studied using an anatomic and computed tomographic comparison. The propria fascia (lateroconal fascia) divided into the anterior and posterior layers of the perirenal fascia. The fascias delimitate two anterior and posterior pararenal spaces around the kidney compartment and two anterior and posterior perirenal spaces in the compartment itself. These spaces extended above and below the renal compartment from the diaphragm to the pelvis. These large spaces composed of fat and organs can assume the guided migration of pathologic processes or their spread according to the importance of the fascias barriers. They below to the genito-urinary region. The extraperitoneal spaces are related anteriorly to the retroperitoneal alimentary organs: duodenum, pancreas, ascending and descending colon depending of the alimentary region. They are related posteriorly with the abdominal wall and its own fat. The individuality and the interdependance of these three territories (alimentary, genito-urinary and abdominal wall) and their consequences for pathologic CT scan imaging will be discussed in the second part of this paper.

Indications for exploring the retroperitoneal space.

The retroperitoneal space is an area that deserves consideration in patients with serious bleeding problems. This area should be explored in all patients with a history of previous reconstructive vascular surgery of the abdominal aorta and iliac vessels and who subsequently present with gastrointestinal hemorrhage. It should also be considered for exploration in patients presenting with serious bleeding problems when the bleeding site cannot be identified and the area in which blood is accumulating cannot be detected. We present three cases in which early adequate exploration of the retroperitoneal space would have been beneficial to the patients.

[A case of gas gangrene caused by colon diverticulitis with perforation into the retroperitoneal space].

We report a case of retroperitoneal gas gangrene, which was caused by cecal diverticulitis with perforation. A-57-year-old male was admitted to the Sado General Hospital with the chief complaint of right lateral abdominal pain. Roentogenogram and Computelized Tomography (CT) showed gas accumulation in the retroperitoneal space behind the ascending colon. Based on the clinical, labolatory, and instrumental examination findings gas gangrene was diagnosed. Since urolithiasis or urinary tract infection was suspected to be the cause of the lesion at that time, the patient was transferred to our department immediately. CT scan done on day 3 at our inpatient department provided data suspicious for the cecal perforation into retroperitoneal space due to appendicitis or diverticulitis. We performed an acute drainage of the abscess and intensive care including continuous hemodiafiltration (CHDF), oxygen under high pressure (OHP), and chemotherapy with antibiotics was carried out. However, in spite of the above mentioned measures, the patient's condition deteriorated and he died due to progression of gangrene and multiple organ failure in 23 days. The autopsy revealed that the cause of perforation was cecal diverticulitis. Retroperitoneal gas gangrene is an uncommon entity and has been rarely reported. It is supposed that laparotomy with diagnostic and therapeutic purpose should have been performed in this case.

[Computed tomographic anatomy of the kidneys and the retroperitoneal space].

The authors described the anatomy of the kidneys and retroperitoneal space in health on the basis of CT of 90 patients. Five typical levels in CT (ensuring all necessary data on roentgenomorphological traits of the kidneys and retroperitoneal space in the kidney area) were singled out. Some roentgenometric data on kidney cross-sections as well as the quantitative densitometric characterization of the parenchyma of the kidneys, renal sinus and adjacent tissues were presented. X-ray anatomy of the renal fascia, pararenal space and perirenal fatty space of the kidney with different parts of the retroperitoneal space was described.

[A case of hamartoma of the retroperitoneal space].

A case of hamartoma of the retroperitoneal space in a 59-year-old woman is reported. Excretory urography, computed tomography and adrenal angiography revealed a tumor with multiple calcification in the left retroperitoneal space. The tumor measuring 6.5 by 3.5 cm, and weighing 30 gm, was removed operatively. Removed specimen consisted of many cysts of various sizes containing mucous fluid and multiple small stones. Microscopically, the tumor was composed of a tubular structure lined by ciliated, epithelium-like tissue of the respiratory system or that of Fallopian tube. These tubules were occasionally dilated cystically. No atypical cells were found. The postoperative course was uneventful.

[Antibiotic transfer into tissue after total hysterectomy with special reference to the cefmetazole concentration of the retroperitoneal space exudate].

The intent of the study was to investigate the transfer of CMZ to the retroperitoneal space exudate after hysterectomy (11 cases of simple abdominal hysterectomy and 6 cases of radical hysterectomy). Concentration of CMZ in the lymphnode was also measured in 2 cases. The results were as follows. Concentration in the retroperitoneal space exudate of CMZ after administration (intravenous drip infusion 1 or 2 g/hour) reached its peak 2 hours after administration (approximately 1 hour later than its peak in the blood). The peak level in the exudate was 1/3 to 2/3 of the peak level in the blood. After 2 hours, the concentration of CMZ in the exudate decreased gradually. The concentration of CMZ in the retroperitoneal space exudate in cases of simple abdominal hysterectomy was higher than in those of radical hysterectomy. After 1 to 3 days of radical hysterectomy, the transfer of CMZ into the exudate was as good as the transfer of that in the period immediately after operation. CMZ concentration in the lymphnode in the cases of radical hysterectomy reached 9 to 13 micrograms/mg approximately 1 hour after the start of CMZ administration (d.i. 2 g in 1 hour). Research results suggest that lymph circulation, in addition to blood stream, plays an important role in the transfer of antibiotics toward the pelvic dead space.

[Study on the TIL and NK of IL-2 injected via pelvic retroperitoneal space in gynecological cancer patient].

OBJECTIVE: To verify the feasibility and effect of biotherapy instituted via pelvic retroperitoneal space on gynecological cancer. METHODS: Injecting IL-2 (and/or) 5-Fu through a tube installed in the pelvic retroperitoneal space. Counting the subpopulation of T cell and NK of lymph-nodes of pelvis after the drugs being by FCM. RESULTS: The numbers of CD3+, CD4+, CD8+, CD25+ and NK cells in treatment group were significantly higher than those in the control group. And the numbers of these cells in the IL-2 + 5-Fu group were significantly higher than those in the 5-Fu group. The CD25+ and NK cell numbers in the IL-2 group were significantly higher than those in the 5-Fu group (P < 0.05). CONCLUSION: The IL-2 injected via pelvic retroperitoneal space can promote the activity, development and infiltrating of T cell and NK cell in the tumor tissue.

[Effect of vaginal antibiotics suppository on retroperitoneal-space infection after hysterectomy and lymphadenectomy for uterine cancer].

Effects of vaginal antibiotics suppository on the retroperitoneal-space infection were studied in 42 patients who had hysterectomy and lymphadenectomy with diagnosis of uterine cancer stage I or II. All patients received intravenous administration of 1 g LMOX (3 times/day) for 7 days after operation. One group of patients (21 cases) received 0.5 g of ABPC vaginal suppository (twice/day) for 10 days immediately after operation. Another group of 21 patients did not received vaginal suppository. The LMOX concentrations in the exudate decreased rapidly from the 3rd day to the 7th day. The frequencies of bacterial appearance in the retroperitoneal-space in the vaginal suppository group were 33% on 5th day, 33% on 7th day and 20% on 9th day, while those in the control group were 100%, 100% and 76%, respectively. It was concluded that the administration of vaginal antibiotics suppository was easy to handle and effective for preventing the retroperitoneal-space infection after hysterectomy and lymphadenectomy.

A new approach for accessing retroperitoneal space using a 5-mm [corrected] visual access cannula.

Retroperitoneal lymph node evaluation is a very important step in planning cancer therapy. Traditional staging laparotomy is too invasive and causes considerable morbidity. However, laparoscopic access of the retroperitoneal space offers the onco-endoscopist a unique, noninvasive, and less dangerous method for assessing and managing women with gynecologic malignancies. The retroperitoneal approach is noninvasive and less dangerous way of accessing the paraaortic space. A new minimally invasive approach of accessing the retroperitoneal space using a 5-mm visual access cannula is introduced. A complete paraaortic and pelvic lymphadenectomy was possible for 60 patients with varied gynecologic malignancies using our retroperitoneal laparoscopic approach. Less blood loss and rapid recovery was observed, and no bowel complication was encountered. The use of the 5-mm visual access cannula offers a less invasive surgical procedure and provides cosmetic advantages.

Chronic expanding hematoma in the retroperitoneal space: a case report.

A case of retroperitoneal chronic expanding hematoma complicated with hydronephrosis, which was difficult to diagnose preoperatively, is reported. The patient was a 70-year-old man. An 18 cm mass was detected in the right retroperitoneal space on abdominal CT screening. There were small calcifications in the periphery of the mass that were strongly enhanced in the delayed phase of dynamic CT. The mass involved the right ureter and iliopsoas muscle, resulting in severe hydronephrosis. The histological diagnosis was chronic expanding hematoma.

Computed tomography of the retroperitoneal space.

Computed body tomography is an easily accomplished method that precisely displays the normal and pathologic anatomy of the retroperitoneal space. Suspected retroperitoneal disorders, which are often clinically confusing or obscure, can now be detected or excluded with remarkable accuracy. Few innovations in radiology have more effectively fulfilled such a conspicuous need.

[Cases of carcinoid tumor in stomach and retroperitoneal space].

Authors present two cases of carcinoid localized in stomach and retroperitoneal space. Diagnosis was based on clinical examination, endoscopy, CT and histopathological evaluation. The case of gastric carcinoid was an early lesion (penetrated only mucose and submucose layer of gastric wall). In opposition, second patient had inoperable large tumor localized in retroperitoneal space with multiple metastases to the liver.

[Mini-invasive surgery of the retroperitoneal space in children].

UNLABELLED: Although laparoscopic surgery now represents today an essential surgical technique, its use remains limited in urology and especially in pediatric urology for many reasons, main because of the lack of indications. After a large experience acquired in abdominal laparoscopic surgery, and because we were convinced of the advantages offered by this new mini-invasive approach, we have tried to develop it for the retroperitoneal space. METHODS: Over a five-year period we performed 88 retroperitoneal procedures in children:--50 nephrectomies (44 total, 10 partial) for the following indications: 15 polycystic dysplastic kidney, 13 kidney destroyed by reflux, 18 by obstruction, hypertensive uropathy 3, pyonephrosis 1.--5 renal cystectomies, 3 pyelolithotomies, 2 pyeloureteral obstructions, 2 adrenalectomies, 1 retrocaval ureter, 25 varicoceles. The age range was 2 months to 16 years (mean: 3.7 years, 25 children under 1 year). The patients were placed in the lateral debubitus. The retroperitoneal space was created by dissection under direct vision, then insufflation was performed directly in the retroperitoneal space without balloon. Three or four ports were used except for varicocelectomy which was performed with only one port and an operating channel telescope. RESULTS: Follow-up range was 6 months to 5 years. The mean operating time was 96 minutes (35 to 210 min.). Average postoperative stay was 2 days. Conversion was needed in 7 cases (8%). Operative incidents consisted of one duodenal perforation, one ureteral burn, 21 peritoneal perforations (24%). There were 5 postoperative complications (2 urinomas after partial nephrectomy, 1 hydrocele, 1 varicocele recurrence, 1 recurrent stones) not related to the technique. 3 cases needed reoperation (ureteral injury, varicocele recurrence, recurrence of cystine stones) with good result. CONCLUSION: Like other laparoscopic techniques, retroperitoneoscopy requires a training: it remains delicate in children because of the reduced working space and the fragility of the peritoneum. However the advantages seem sufficiently obvious for us to recommend and promote this procedure.

[Benign non-organ-related diseases of the retroperitoneal space].

Because of the anatomic localisation of the retroperitoneal space, the detection and elucidation of pathology in the retroperitoneum calls for clinical acumen and the utilisation of imaging techniques. During the past two decades, efforts spearheaded by the work of M. A. Meyers led to an enhanced understanding of retroperitoneal anatomy and pathology. Conventional radiographic techniques are often incapable of detecting and/or characterising retroperitoneal abnormalities. Sonography may be limited by patient-dependent-factors. CT is unaffected by bowel gas and provides discrete cross-sectional images of the organs, fascial planes and retroperitoneal compartments, making it an ideal tool for assessment of retroperitoneal disease. In clinically stable patients MRT may be a useful modality for providing helpful and additional information in characterising retroperitoneal abnormalities. In this review article the diagnostic possibilities of benign not organ-related diseases of the retroperitoneum are described. This is intended to give the reader an insight into the etiology and distribution patterns of retroperitoneal fluid and gas collections as well as into diagnosis and differential diagnosis of benign retroperitoneal diseases. The diagnostic impact of the different imaging modalities is discussed.
