Aggressive management of nonocclusive ischemic colitis following aortic reconstruction.

HYPOTHESIS: Under standard conditions following aortic reconstruction, nonocclusive ischemic colitis (IC) type 1 (mucosal ischemia) and type 2 (mucosal and muscularis ischemia) can be managed nonoperatively, whereas type 3 (transmural ischemia) requires emergency surgery. Our objective was to standardize the surgical approach for IC complicating aortic reconstruction. DESIGN: Retrospective cohort study. SETTING: General surgery, vascular surgery, anesthesiology, and critical care units in a university-affiliated hospital. METHODS: From January 5, 1997, to December 15, 2003, 49 cases of IC complicating aortic reconstruction were diagnosed (rate, 2.7%). Nonoperative management was used for patients with type 1 or type 2 without multiple organ failure (MOF). All patients with type 3 or with type 2 with MOF underwent urgent resection of the ischemic colon without anastomosis. RESULTS: Immediate surgery was performed on 24 patients (49.0%). Nineteen (76.0%) of 25 patients without MOF and with transient endoscopic findings underwent secondary surgery for progression to final IC type 3 (16 patients) or to final IC type 2 with MOF (3 patients). Twenty-three (53.5%) of 43 patients died after colorectal resection (overall mortality, 46.9%). Factors causing significant risk of death were surgery, MOF, final IC type, and amount of perioperative transfusion. The mortality was 57.1% for final IC type 3, 37.5% for final IC type 2 with MOF, and 0% for final IC type 1 or type 2 without MOF. CONCLUSIONS: Selective management of postoperative IC, based on MOF and the degree of ischemia, is the suggested course of action. For patients with mild ischemia and MOF, an aggressive approach is recommended.

Diagnosis of bowel and mesenteric injuries in blunt abdominal trauma: a prospective study.

PURPOSE: Currently, nonoperative management is the procedure of choice for solid organ injury in patients with a blunt abdominal trauma. Missed blunt bowel and mesenteric injuries (BBMIs) are possible because diagnosis is difficult. The aim of our study was to test a new algorithm for BBMI diagnosis using abdominal ultrasonography (AUS), computed tomography (CT), and diagnostic peritoneal lavage (DPL). METHODS: We reviewed cases of blunt abdominal injuries over a 10-year period, then we designed an algorithm that was prospectively tested in hemodynamically stable patients over a 2-year period. An abnormal AUS led to helical CT. When the CT showed more than 2 findings suggestive of BBMI, laparotomy was performed. In case of 1 or 2 abnormal CT findings, we performed a DPL and calculated the ratio of white blood cells (WBCs) to red blood cells (RBCs) (WBC/RBC ratio) in the lavage fluid and divided this by the WBC/RBC ratio in peripheral blood. A ratio of 1 or higher was considered positive for BBMI, and a laparotomy was immediately performed. Patients with a ratio of less than 1 were managed nonoperatively. RESULTS: In the retrospective study, 26 (1%) of 2126 patients admitted to our trauma center for blunt trauma had a BBMI, including 15 (58%) diagnosed after a median delay of 24 hours. In the prospective study, 531 patients were admitted for blunt trauma with multiple injuries, including 131 with abdominal trauma. Computed tomography was performed in 40 patients. There were 2 criteria or more of BBMI in 1 patient, 0 criteria in 27 patients (with an uneventful follow-up), and 1 or 2 criteria in 12 patients who had DPL with a median ratio of 0.82 (ranges, 0.03-9). Five patients had a ratio of 1 or higher. They underwent immediate laparotomy. In all 5 cases, BBMI was found. The 7 patients who had a ratio of less than 1 were observed in ICU and treated for extra-abdominal injuries. No BBMI injury was missed in these patients. The accuracy of the algorithm was 100% (95% confidence interval, 0.99-1.00). CONCLUSION: The proposed algorithm (based on AUS, CT, and DPL) had a high accuracy to diagnose BBMI while requiring the performance of DPL in only a few (2%) patients.

Extensive thyroidectomy in Graves' disease.

BACKGROUND: The best surgical treatment for hyperthyroidism caused by Graves' disease remains a controversial subject. METHODS: Seven hundred fourteen consecutive patients underwent total or near-total thyroidectomy for Graves' disease in a 13-year period. In a first analysis, postoperative rates of suffocating hematoma, wound infection, recurrent laryngeal nerve (RLN) palsy, hypoparathyroidism, and persistence or recurrence of hyperthyroidism, were studied and compared with the same parameters in 4,426 patients who underwent bilateral thyroid gland resection for other conditions. A second analysis identified factors associated with postoperative complications among Graves' disease patients. RESULTS: Comparing Graves' disease patients with patients who had bilateral thyroid resection for other conditions, the transient morbidity rate was 13.3% versus 8.2% (p < 0.0001), with 10.2% versus 5.0% (p < 0.0001) hypoparathyroidism, 2.2% versus 1.7% (p = 0.35) RLN palsy, 1.7% versus 0.9% (p < 0.05) suffocating hematoma, and 0.3% versus 0.4% (p = 0.67) wound infection, respectively. Permanent morbidity rate was 2% versus 2.2% (p = 0.72), including 0.4% versus 0.6% RLN palsy and 1.5% versus 1.7% hypoparathyroidism. Among the Graves' disease patients, univariate analysis revealed that those who experienced postoperative complications had a higher weight resected thyroid gland (odds ratio = 1.5; 95% CI, 1.0-2.3) and a higher rate of total thyroidectomy (24.4% versus 19.5%, odds ratio = 2.2; 95% CI, 1.4-3.4) than patients without complications. In the multivariable model, these two factors remained independent. There was no recurrence of hyperthyroidism with a median followup of 6.7 years (interquartile range 4.1 to 10.1 years). Persistent hyperthyroidism developed in three patients. CONCLUSIONS: Total or near-total thyroidectomy is an effective and safe treatment for Graves' disease when performed by an experienced surgeon.

[Spontaneous splenic rupture during intrasplenic Kaposi's sarcoma in an HIV-positive patient].

Spontaneous splenic rupture is a rare cause of peritoneal bleeding. Etiology is usually infections (viral, bacterial or parasitic) and blood diseases (leukemia, lymphoma, dysglobulinemia). We report the first case of spontaneous splenic rupture secondary to hilar Kaposi's sarcoma in an HIV positive patient. Emergency splenectomy was performed to achieve hemostasis, and the etiological diagnosis of this spontaneous splenic rupture was based on the histological analysis.

Small-bowel infarction from disseminated aspergillosis.

INTRODUCTION: Despite the use of new, effective drugs, the disseminated invasive aspergillosis often remains lethal in neutropenic patients. Diagnosis is difficult because early symptoms are nonspecific. New tools could help in diagnosis and lead to early surgery when needed. METHODS: A neutropenic patient developed an acute abdomen. CT findings were a diffuse, small-bowel distention with a thickened, distal, ileum wall. Emergency surgery was performed with resection and immediate anastomosis of the distal ileum. Pathology of the small bowel showed a wall necrosis and invasion by Aspergillus fumigatus. RESULTS: The postoperative course was uneventful except for persisting diarrhea secondary to a coexistent infection with Clostridium difficile. Aspergillus antigene in serum was positive, whereas neither pulmonary nor central nervous system aspergillosis was observed on CT scan. CONCLUSIONS: This diagnosis should be considered when neutropenic patients show abdominal pain and distention with fever. Repetition of Aspergillus antigenemia, search for others aspergillosis localizations, CT scan, and colonoscopy with biopsies should be performed until diagnosis allows the administration of early antifungal therapy.

[Cystadenoma of the liver with high levels of ACE and CA 19-9 in the cyst].

The development of a cystadenocarcinoma from previously benign cystadenoma is controversial. Neither clinical nor biological factors have been described to explain this transformation. High levels of serum and cystic CEA and CA 19-9 seem to help in the diagnosis of cystadenoma but not cystadenocarcinoma. Definitive histological evaluation is the only means to discriminate malignant from benign cysts. We report a case of cystadenoma of the liver with very high cystic levels and normal serum levels of CEA and CA 19-9.
