Part Three of Three-Part Series: Colorectal Surgery Review for Primary Care Providers

Malignant colon and rectal disorders must be identified and treated. Timing and indication for diagnostic and screening colonoscopy are extremely important. A high index of suspicion to exclude malignancy is imperative. This paper will focus on the screening for and treatment of colorectal and anal cancers.

Colorectal Surgery Review for Primary Care Providers

Colon and rectal disorders can be functional and inflammatory. This is the second paper of a three-part series14 and will focus on the diagnosis and treatment of rectal prolapse, fecal incontinence and inflammatory bowel disease.

Colorectal Surgery Review for Primary Care Providers

Anorectal conditions are one of the most common problems evaluated by primary care physicians. Most patients present with rectal pain, rectal bleeding, or purulent drainage per rectum. Colorectal conditions have overlapping symptoms. Thorough history and careful anorectal examination can differentiate common anorectal conditions like hemorrhoids, anorectal abscesses, anal fistula, anal fissure, and anal condyloma. Most of these conditions can be diagnosed and treated without imaging.

Use of computed tomography findings and contrast extravasation in predicting the need for embolization with pelvic fractures

Transarterial embolization (AE) can be a lifesaving procedure for severe hemorrhage associated with pelvic fractures. The purpose of this study was to identify demographic and radiographic findings that predict the need for embolization. We performed a retrospective review of all patients with at least one pelvic fracture and admission to the intensive care unit over a 35-month period. Computed tomography (CT) and pelvic radiographs were reviewed. Patient demographics, outcomes, time to angiography, and whether or not embolization was performed were determined. Statistical analysis was used to determine factors associated with the need for AE. Of the 327 total patients with pelvic fractures, 317 underwent CT scanning. Forty-four patients (13.5%) underwent angiography and 25 (7.6%) required therapeutic embolization. There were 39 total deaths (11.6%) with five deaths related to pelvic hemorrhage (1.5%). Multivariate analysis revealed that age older than 55 years (odds ratio [OR], 1.06; P < 0.001), systolic blood pressure less than 90 mmHg in the emergency department (OR, 11.64; P = 0.0008), and CT extravasation (OR, 147.152; P < 0.0001) were significantly associated with the need for embolization. Contrast extravasation was not present in 25 per cent of patients requiring therapeutic AE. The presence of contrast extravasation is highly associated with the need for pelvic embolization in patients with pelvic fractures, but its absence does not exclude the need for pelvic angiography.

Gangrene therapy and antisepsis before lister: the civil war contributions of Middleton Goldsmith of Louisville

It is commonly accepted that Louis Pasteur is the father of microbiology and Joseph Lister is the father of antisepsis. Middleton Goldsmith, a surgeon in the Union Army during the American Civil War, meticulously studied hospital gangrene and developed a revolutionary treatment regimen. The cumulative Civil War hospital gangrene mortality was 45 per cent. Goldsmith's method, which he applied to over 330 cases, yielded a mortality under 3 per cent. His innovative work predated Pasteur and Lister, making his success truly remarkable and worthy of historical and surgical note.
