Laparoscopic versus open colonic resection for complicated diverticular disease in the emergency setting: a safe choice? A retrospective comparative cohort study

Background

We conducted a retrospective cohort study to compare the outcomes of laparoscopic colon resection (LCR) with open colon resection (OCR) for complicated diverticular disease (CDD) during emergent hospital admission.

Methods

Charts from all patients undergoing colon resection for CDD during emergent hospital admission at a single academic institution were reviewed. The primary outcomes were overall 30-day postoperative morbidity and mortality.

Results

From 2000 to 2010, 125 cases were retrieved (49 LCR and 86 OCR). Conversion rate was 5.1%. Overall morbidity significantly decreased with laparoscopic surgery compared with OCR. No mortality occurred with LCR. Prolonged ileus was less frequent (12.8% vs 32.6%; P = .02), time to oral intake shorter (3 vs 6 days; P < .01), and LOS shorter (5 vs 8 days; P = .05) for LCR.

Conclusions

In our series, in the patients selected, LCR for CDD during emergent hospital admission appears to be a safe procedure associated with decreased morbidity, time to oral intake, and LOS compared with OCR.     

Refractory hypoxemia in inferior myocardial infarction from right-to-left shunting through a patent foramen ovale: A case report and review of the literature

Right ventricular (RV) infarction is a well-recognized complication of some acute inferior myocardial infarctions. Recently, there have been numerous case reports of RV infarctions complicated by severe refractory hypoxemia secondary to right-to-left shunting through a patent foramen ovale. An additional case missed by transthoracic echocardiography and cardiac catheterization is reported and the English literature on the subject is reviewed.     

Longterm course of mixed cryoglobulinemia in patients infected with hepatitis C virus

OBJECTIVE: To describe epidemiological, clinical, and immunological characteristics and the longterm course of persistent mixed cryoglobulinemia (MC) in patients infected with hepatitis C virus (HCV). METHODS: Retrospective study of HCV infected patients (HCV RNA positive) who had persistent positive MC, with 2 immunochemical typings of MC carried out after 24-month minimum interval. RESULTS: In total, 125 patients were studied, aged 52 +/- 13 years at diagnosis of MC, with duration of HCV infection of 18 +/- 10 years. At entry, 60 patients had type II MC, 53 patients had type III, and 12 patients had the oligoclonal type. At the second immunochemical typing, after a mean interval of 45 +/- 20 months, MC was type II in 72 patients, type III in 39 patients, and the oligoclonal type in 14 patients. The proportion of cases of MC with the same immunochemical type was higher among patients with type II (78%) than type III (59%) or oligoclonal MC (17%) (p < 0.01). The MC that changed turned more to type II (55.5%) than type III (29%) or the oligoclonal type (15.5%) (p = 0.0002). MC vasculitis (purpura, arthralgia, peripheral neuropathy, renal involvement) and other extrahepatic manifestations (polyarteritis nodosa, lymphoma) in 60/125 patients was associated with advanced age (p < 0.01), a longer duration of infection (p < 0.05), type II MC (odds ratio = 5, p < 0.01), and a higher MC serum level (p < 0.01). CONCLUSION: During chronic active HCV infection, type II MC is more stable over time than type III and oligoclonal MC. The oligoclonal type appears to be an intermediate stage in the course of type III changing to type II MC. Symptomatic persistent HCV MC was associated with advanced age, longer duration of HCV infection, type II MC, and a higher MC serum level.
