A rare surgical complication of Crohn's diseases: free peritoneal perforation.

BACKGROUND: Free peritoneal perforation is a rare complication of Crohn's disease. METHODS: We evaluated the incidence of free peritoneal perforation among 208 patients with Crohn's disease surgically treated in the period 1992-2000. RESULTS: Five patients (2.4%) suffered from free peritoneal perforation. In 1 patient free peritoneal perforation was the first symptom of Crohn's disease. In 3 cases the perforation was in the small bowel and in 2 in the large bowel. All patients underwent surgery: all cases had a resection of the involved bowel and in two cases an ileostomy was performed in order to prevent severe peritonitis. We did not observed mortality or major complications. CONCLUSIONS: Free peritoneal perforation is rare with about 100 cases reported in literature. No correlation seems to exist with previous corticosteroid treatment. The surgical treatment is mandatory. Simple suture should be avoided. The most appropriate treatment, whenever it is feasible, is resection of the involved bowel with immediate or, in case of severe sepsis, delayed anastomosis.

Secondary peritonitis: severity of disease and activation of peritoneal cells.

OBJECTIVE: To compare the degree of the inflammatory response of human peritoneum with the severity of peritonitis. DESIGN: Clinical laboratory study. SETTING: University hospital, Germany. SUBJECTS: 15 patients with diffuse secondary peritonitis and 5 having conventional cholecystectomy (controls) had peritoneal specimens taken from the site of incision. MAIN OUTCOME MEASURES: Correlation between presence of indicators of the inflammatory response: interleukin 1 (IL-1), interleukin 6 (IL-6), intercellular adhesion molecule-1 (ICAM-1), antibacterial protein (defensin 3 reflecting the activation of granulocytes), the antibody clone HAM 56 (for detection of local macrophages), and antibodies against macrophage migration inhibiting factor (MIF)-related proteins 8 and 14 (MRP 8 and 14), and clinical state evaluated by the Mannheim Peritonitis Index (MPI), the Peritonitis Index Altona II (PIA II) and the Acute Physiology Score (APS). C-reactive protein (CRP) concentrations were measured preoperatively in the serum. RESULTS: Expression of MRP 8 and 14, HAM 56, and defensin 3 was significantly higher in patients with peritonitis than in controls (p < 0.05). Expression of IL-1 and IL-6 was almost undetectable. ICAM-1 expression correlated significantly with phagocytic activation. There was no correlation between clinical scores, CRP, and immunohistochemically detectable variables. CONCLUSION: The pattern of peritoneal inflammatory reactions is relatively uniform and does not correlate with the clinical grading of severity.

Prevalence of gastroesophageal reflux disease in peritoneal dialysis and hemodialysis patients.

The prevalence of gastrointestinal reflux disease (GERD) in hemodialysis (HD) and peritoneal dialysis (PD) patients was assessed at a single center with a self-administered questionnaire previously used in a general population. It defines (GERD as the presence of heartburn or acid regurgitation, or both. Risk factors for GERD and GERD-associated symptoms were also evaluated. In the studied population, 29.7% of patients had frequent GERD (heartburn, acid regurgitation, or both symptoms weekly). Frequent GERD was reported by 44.7% of PD patients versus the 18.9% reported by HD patients and the 19.8% reported by the general population. PD and HD patients had similar GERD severity scores [2.3 +/- 0.7 vs 1.9 +/- 0.8, mean +/- standard deviation (SD)]. PD and HD patients reported atypical GERD symptoms at rates similar to those reported by the general population, but having GERD made some atypical GERD symptoms more likely (p < 0.05, Fisher's exact test). In a logistic model, age < 60 [odds ratio (OR) 5.6, confidence interval (CI) 1.5-21.3], smoking (OR 4.7, CI 1.3-16.9), and body mass index > or = 27 (OR 3.9, CI 1.2-13.0) predicted GERD. Sex, race, diabetes, PD, non steroidal anti-inflammatory drugs (NSAIDs), calcium channel blockers, and coffee and alcohol use did not. GERD is more common in PD patients than in HD patients or in the general population. It is not clear whether PD per se is a risk factor for GERD.

US of the peritoneum.

Familiarity with the pathophysiology of peritoneal disease is the basis of successful ultrasound (US) study of the peritoneum. The pouch of Douglas, diaphragmatic surfaces, the paracolic gutters, and the regions of the mesentery and omentum should receive careful scrutiny in the patient at risk for a peritoneal disease process. An optimal US technique requires assessment of the entire peritoneum with a transducer selected to reflect the depth of the region of interest. US may demonstrate minute quantities of free intraperitoneal fluid and is therefore capable of providing sensitive quantitative information about ascites. Qualitative information may also be inferred, as blood, pus, and neoplastic cells demonstrate correlation with particulate ascites on gray-scale US scans. Peritoneal nodules, plaques, and thickening may be detected on the visceral or parietal peritoneal surfaces, especially when high-frequency probes are used. Transvaginal study in women increases the sensitivity of US for detection of peritoneal disease. In women who have unexplained sepsis or are at risk for carcinomatosis, transvaginal scanning should routinely be added to the regular abdominal and pelvic studies regardless of the findings of those studies. Peritoneal carcinomatosis, primary peritoneal neoplasms, pseudomyxoma peritonei, and peritonitis have characteristic appearances at US.

[Prognostic factors and treatment for advanced-stage borderline ovarian tumors].

OBJECTIVE: The aim of this review is to study the incidence, the prognostic factors and the treatment of patients with advanced stage borderline ovarian tumor (BOT) associated with extra-ovarian disease (peritoneal implants and/or nodal disorders). METHODS: Review of literature data. RESULTS: BOT were associated with peritoneal implants in 15% to 40%. The strongest prognostic factors are the histologic subtype of peritoneal implants and the presence of residual disease. The surgical treatment is the gold standard with resection of all peritoneal disease. This surgery could be conservative in selected cases in order to preserve fertility. Noninvasive peritoneal implants do not seem to be chemosensitive lesions. CONCLUSION: Histologic subtype of peritoneal implants is the most important prognostic factors in patients with serous BOT and extra-ovarian spread. The prognosis of patients with noninvasive implants is good. Treatment is based on surgery. The (only) indication of adjuvant therapy is BOT associated with invasive implants.

Peritoneal carcinomatosis: role of (18)F-FDG PET.

UNLABELLED: Peritoneal carcinomatosis can be difficult to diagnose, as CT is insensitive, with peritoneal biopsy and lavage often subject to problems of sampling error. The aim of our study was to evaluate the role of (18)F-FDG PET in detecting peritoneal carcinomatosis in patients with stomach, ovarian, and adrenal cancer and mesothelioma and to compare the results with CT scans in the same patient group. Our secondary aim was to identify characteristic patterns of abdominal (18)F-FDG uptake in biopsy-proven peritoneal disease and to correlate these patterns with available histologic and anatomic findings after surgery and structural imaging. METHODS: The medical records of 88 patients with stomach (n = 48), ovarian (n = 13), and adrenal cancer (n = 6) and mesothelioma (n = 21) were reviewed for the presence of peritoneal tumor on (18)F-FDG PET and CT scans. The results were correlated with either contemporaneous peritoneal biopsy or ascitic aspirate or with radiographic or clinical follow-up if histology was negative or unavailable. Of 24 patients with suspected peritoneal tumor, 17 had biopsy-proven findings of peritoneal disease. RESULTS: Of the 24 patients with suspected peritoneal tumor, (18)F-FDG PET was positive in 14 patients, with 1 of these scans being false-positive, CT was positive in 10 patients, and either PET or CT was positive in 18 patients. This yielded sensitivities of 57% (13/23), 42% (10/23), and 78% (18/23), with uniformly high positive predictive values of 93% (13/14), 100% (10/10), and 95% (18/19), respectively. We identified 2 distinctly abnormal scintigraphic patterns of focal and uniform (18)F-FDG uptake corresponding to nodular and diffuse peritoneal disease on pathologic examination. CONCLUSION: (18)F-FDG PET adds to conventional imaging in the staging of peritoneal carcinomatosis. It is also a useful diagnostic tool when peritoneal biopsy is either unavailable or inappropriate. We have identified 2 distinct scintigraphic patterns that appear to predict the presence of either nodular or diffuse peritoneal pathology.

[Vaccination against experimental peritoneal hydatid disease of BALB/C mice with hydatid fluids and their fractions (author's transl)].

The Authors studied the protective action of some vaccine (pool of hydatid fluids from bovine and ovine origin and their fractions) on the experimental peritoneal hydatid disease of BALB/C mice. It has been demonstrated that some pool of concentrated ovine hydatid fluids and the chromatographic "heavy" fraction of one of them, had some protective action. The results are briefly discussed.

Focal glomerulosclerosis in Hodgkin's disease necessitating peritoneal dialysis.

A 16-year-old white boy had nephrotic syndrome due to focal segmental glomerulosclerosis six months before the diagnosis of Hodgkin's disease was established. Peritoneal dialysis was necessary for volume control after one month of unsuccessful therapy with high doses of corticosteroids. Nephrosis remitted after two courses of chemotherapy.

Colon cancer with metastasis to the ovary at time of initial diagnosis.

Colon cancer with a synchronous ovarian metastasis is occasionally diagnosed at the time of laparotomy for a pelvic mass. The purpose of this retrospective study is to evaluate the clinical presentation as well as the impact of the type of metastatic spread and surgical intervention on overall survival. We reviewed charts of 23 patients treated between 1980 and 1995. Pain was the initial symptom in 14 patients (61%), with only four patients (17%) complaining of rectal bleeding, but with five patients (22%) complaining of uterine bleeding. At the time of laparotomy, the ovarian capsule was intact in 12 patients. Metastatic disease to the peritoneum was seen in seven patients and to the liver in six patients. On pathological evaluation, the median ovarian tumor size was 10 cm, significantly larger than the median colon tumor size of 4.5 cm. Surgical treatment consisted of colon resection in all but one patient, bilateral or unilateral salpingo-oophorectomy in 22 patients, and hysterectomy in nine patients. Only one patient survived 5 years. Sixteen patients died of colon cancer. The median survival time was 17.8 months, ranging from 1 to 86 months. Tumor size was of no prognostic importance. Median survival time of patients with peritoneal disease (10.8 months) was significantly shorter compared to patients without peritoneal disease (25.2 months). In the presence of liver metastasis, the median survival time was, likewise, significantly reduced from 20.1 months to 8.1 months. In conclusion, macroscopic metastatic disease to the ovary is a poor prognostic factor in colon cancer. In selected patients who can be rendered disease-free by surgery, prolonged survival is possible and an aggressive approach is recommended. Survival of patients with peritoneal disease or liver metastasis is short and a mainly palliative approach is recommended.

C-reactive protein and cardiovascular disease in peritoneal dialysis patients.

BACKGROUND: Elevated plasma concentrations of C-reactive protein (CRP) is a risk factor for cardiovascular disease (CVD) in the general population and in hemodialysis patients. The prognostic value of CRP is less well known in peritoneal dialysis (PD) patients. We examined the association between CRP and cardiovascular event (CVE) in a large population of PD patients. METHODS: Two hundred and forty patients starting PD were enrolled in this prospective study. The role of CRP was analyzed with respect to other known cardiovascular risk factors. RESULTS: The patients were followed for a mean duration of 41 +/- 21 months; the median value of CRP was 7 mg/L. Eighty-nine cardiovascular events (CVE; 37.1%) occurred in 84 patients and the CRP levels were higher in patients who experienced CVE (27 +/- 14 vs. 6 +/- 8 mg/L; P < 0.0001). In the Cox model, patients in the three lower quartiles of the CRP levels had a decreased risk of CVE compared with those in the highest quartile. Cox regression analysis also revealed that age, a previous history of cardiovascular disease, hyperhomocysteinemia and hypoalbuminemia were risk factors for CVE. CRP levels were higher in patients who died during the study period (25 +/- 12 vs. 5 +/- 8 mg/L; P = 0.003). In the Cox model, patients with CRP levels above the median had an increased risk of death compared with those in the lowest quartile. CONCLUSIONS: Chronic inflammation, as reflected by elevated CRP levels, is frequent in patients starting PD and independently contributes to an increased incidence of CVE in this population.

Surgical procedure in patients with ovarian cancer diagnosed at the time of prophylactic oophorectomy. Analysis of two cases, literature review and surgical implications.

The aim of this study was to discuss the surgical management for ovarian or tubal cancers diagnosed at the time of prophylactic oophorectomy. Two patients with BRCA1 & BRCA2 mutations carriers had ovarian cancer diagnosed during laparoscopic oophorectomy. Conversion to laparotomy was performed in order to complete surgery (hysterectomy, multiple peritoneal biopsies, omentectomy, pelvic and para-aortic lymphadenectomy). These two patients were upstaged on the basis of para-aortic lymphadenectomy and had massive nodal spread into para-aortic area. One of them had no intra-peritoneal disease and the other one had minor peritoneal disease (only one positive pelvic biopsy in the Douglas pouch). These two patients are alive, one of them with 3.5 years of follow-up after the end of adjuvant treatment. In order to ensure the exact spread of the disease. Lymphadenectomy should be performed in patients with ovarian cancer diagnosed at the time of prophylactic surgery.

Surgical resection and intraperitoneal chemotherapy for recurrent abdominal sarcomas.

BACKGROUND: Recurrent abdominal sarcomas have an extremely high rate of recurrence and poor overall survival. A prospective study was initiated to assess the feasibility, toxicity, and benefit of surgical resection and intraperitoneal chemotherapy for improving local control of disease and overall survival. METHODS: Fifty-four patients underwent surgical excision of all gross disease and postoperative intraperitoneal chemotherapy with mitoxantrone. Thirty-five patients had peritoneal disease only (stage II), and 19 patients had peritoneal disease with hepatic metastases (stage III). RESULTS: Nine (17%) patients remain free of disease with a mean follow-up of 37 months. The remaining 45 patients (83%) have had recurrence, with a mean interval to recurrence of 11 months. Stage (P = .001) and grade (P = .005) were the only two variables found to significantly affect recurrence. There was an overall peritoneal recurrence rate of 48% and an overall hepatic failure rate of 69%. Nineteen (35%) of the patients are alive, with a mean follow-up of 46 months. The overall 5-year survival was 31%. The 5-year survival for stage II patients was 46%; for stage III patients, it was only 5%. Stage (P = .001) and grade (P = .056) were the only two variables found to significantly affect survival. There were no treatment-related deaths, and only 5 patients (9%) developed local complications. CONCLUSIONS: Aggressive surgical resection and intraperitoneal chemotherapy for recurrent abdominal sarcomas is a feasible treatment approach with minimal toxicity. Although this treatment had little effect on the hepatic spread of this disease and thus overall survival, it appears to have significantly lowered the rate of peritoneal recurrence and may provide a survival benefit for patients with disease limited to the peritoneum.

Cytohistologic correlation of peritoneal washing cytology in gynecologic disease.

The peritoneal washings and cul de sac aspirates from 204 patients undergoing 217 procedures for the evaluation of gynecologic disease were examined retrospectively and correlated with the histologic diagnoses. Of the 73 washings from patients with histologically benign genital disease, cytology diagnosed 64 (87.7%) as negative, 6 (8.2%) as inconclusive and 3 as malignant. One malignant washing was a true positive from a nongenital primary. False positives thus occurred in 2.7% of the benign cases on blind review. Of 144 cytologic examinations of washings from patients with histologically confirmed malignant disease of the female genital tract, 38 (26.4%) were considered positive after cytohistologic correlation. Four malignant cases (2.1%) were undercalled on blind review while 3 (2.0%) were considered overcalls. Eleven of 47 cases (23.4%) with biopsy-proven peritoneal disease had negative cytology after histologic correlation. Recurring problems in interpreting peritoneal washings included: (1) the differential diagnosis of the spectrum encompassed by reactive mesothelium, endosalpingiosis, borderline serous tumors and well-differentiated serous cystadenocarcinoma; (2) morphologic similarities between some tumor cells and mesothelial cells associated with treatment effects; and (3) a paucity of malignant cells in some washings, resulting in false-negative interpretations. Ineffective cytopreparation, particularly of bloody specimens, hampered interpretation of some specimens. Correlation with previous histology and cytology enhanced the accuracy of peritoneal washing cytology in this study.
