22. Colorectal Anastomotic Stenosis After Elective Laparoscopic Sigmoidectomy for Diverticular Disease: A Prospective Evaluation of 68 Patients

Author

Ambrosetti, Patrick, Francis, Karim, De Peyer, Reymond, and Frossard, Jean-Louis

Abstract

Abstract: Purpose: This prospective study was designed to find the incidence of symptomatic anastomotic stenosis after elective laparoscopic sigmoidectomy for diverticular disease. Methods: Sixty-eight patients who underwent elective laparoscopic sigmoidectomy with double-stapling colorectal anastomosis between November 1998 and June 2007 were included. Follow-up after hospitalization was performed by using sequential rectoscopy for all patients. Symptomatic patients with anastomotic stricture were treated. Results: No patient died postoperatively and no patient had anastomotic leak or abdominal septic complication. Twenty-two patients (32 percent) had postoperative symptoms that suggested anastomotic stenosis; 12 of them (17.6 percent) eventually needed dilatation of their anastomosis (median diameter of the stenosis: 7 mm) a mean time of 176 days postoperatively. Eight patients had only one session, three patients had two sessions, and one patient had three sessions. There were no complications and all patients were symptom-free after dilatation. Age, sex, obesity, hypertension, diabetes, and vascular preservation had no influence on the risk of anastomotic stenosis. Conclusions: Incidence of symptomatic anastomotic stenosis after elective laparoscopic sigmoidectomy is high (17.6 percent). No risk factor could be identified. Endoscopic dilatations were successful without complication in all cases. Regular rigid rectoscopy definitely should be part of the postoperative follow-up in symptomatic patients.

Abstract

Wilson’s disease is a rare hereditary disorder of copper metabolism leading to progressive accumulation of copper in several organs including the brain and the liver. Acute liver failure is a relatively rare hepatic manifestation of WD which may require urgent liver transplantation if medical treatment fails. We report here the case of a young woman who presented with classic acute Wilsonian hepatitis complicated by liver and renal failure and a severe hemolysis related to massive nonceruloplasmin bound copper accumulation requiring repeated blood transfusions. The early initiation of a combined treatment including conventional chelation therapy and repeated MARS dialysis sessions allowed a rapid control of hemolysis, a progressive decrease of free copper overload, and clinical recompensation without liver transplantation.

Abstract

Bile holds biomarkers of malignant biliary strictures (MBS) but is unsuited for automated analyzers used in routine diagnostic laboratories. Selected reaction monitoring (SRM) is a flexible high-throughput analytical approach based on targeted mass spectrometry (MS) already implemented in clinical settings. We tested the hypothesis that SRM could be used to quantify cancer biomarkers in human bile. An SRM-based assay was developed to simultaneously quantify up to 37 peptides from 13 bile proteins in a developmental cohort of 15 patients (MBS, n = 8; benign biliary stricture or obstruction (BBS), n = 7). The most reliable biomarkers were then absolutely quantified by SRM in a verification cohort of 67 patients (MBS, n = 37; BBS, n = 30). The diagnostic performances of single and combined biomarkers were assessed. In the developmental cohort, SRM-based analysis revealed six protein biomarkers with significantly higher peptide ratios (endogenous vs. standard) in bile from MBS vs. BBS. In the verification cohort, five of these biomarkers proved good diagnostic ability (individual receiver operating characteristic-area under the receiver operating characteristic curve (ROC-AUC) up to 0.889, accuracies from 67.8% to 83.1%). Combining bile biomarkers and serum CA19-9 in 2 panels allowed differentiating MBS from BBS with up to 0.929 ROC-AUC and 89.8% accuracy. In this study, a newly developed SRM-based assay proved able to simultaneously quantify multiple biomarkers in bile samples. The combination of bile biomarkers with serum CA19-9 was highly accurate for the diagnosis of MBS. Liquid biopsy of bile based on targeted MS is eligible to support MBS diagnosis in clinical practice.

Abstract

Acute alcoholic microvesicular steatosis (MIC) may complicate heavy alcohol intake and present as alcoholic hepatitis (AH) syndrome. However, detailed clinical, biological, and histologic data associated with MIC are scarce. We compared the clinical presentation, histologic features, and hepatic transcriptomic of patients presenting with AH due to either MIC or severe alcoholic steatohepatitis (ASH). In this case-control study, patients who drank heavily (>100 g/day) with the AH syndrome were included either in the MIC group (>50% severe microvesicular steatosis, no inflammation) or in the severe ASH group (polynuclear neutrophil infiltration, macrosteatosis, ballooned hepatocytes). All patients received standard supportive care plus steroids for those with severe ASH and were followed up for 3 months. Whole-liver transcriptome profiling was performed on liver snap-frozen biopsies. Compared to ASH (n = 24, mean age 49.3 years), patients in the MIC group (n = 12, mean age 49.1 years) had a higher reported alcohol intake (P < 0.01), lower Model for End-Stage Liver Disease score (P < 0.05), lower hepatic venous pressure gradient (P < 0.01), higher alanine aminotransferase (P < 0.02) and gamma-glutamyltransferase (P < 0.001), higher triglycerides (P < 0.001) and total cholesterol (P < 0.002), but similar bilirubin levels (P = 0.54). At histology, patients with MIC had a lower fibrotic stage compared to those with ASH (P < 0.001). A higher density of megamitochondria was seen in MIC compared to ASH (P < 0.05). During follow-up, death or transplantation occurred in 4/12 (33%) patients with MIC and 7/24 (29%) patients with severe ASH. Differential hepatic gene expression in MIC compared to ASH included down-regulation of genes related to inflammation and fibrosis and up-regulation of genes involved in lipid metabolism and mitochondrial function. Conclusion: MIC is an acute, noninflammatory, potentially severe alcoholic liver injury mimicking ASH, is associated with a lower
