Emergency Presentations of Colorectal Cancer.

Many colorectal carcinomas will present emergently with issues such as obstruction, perforation, and bleeding. Emergency surgery is associated with poor short- and long-term outcomes. For abnormality localizing to the colon proximal to the splenic flexure, surgical management with hemicolectomy is often a safe and appropriate approach. Obstructions are more common in the distal colon, however, where there is an evolving spectrum of surgical and nonsurgical options, most notably by the development of endoluminal stents. Perforation and bleeding are managed similarly to benign causes, as malignancy may be only part of a differential diagnosis at the time of an operation.

Stoma creation: does onset of ostomy care education delay hospital length of stay?

BACKGROUND: Balancing patient safety with hospital length of stay (LOS) and associated cost is critically important. Subjectively, we have observed that patients undergoing ostomy creation early in the week have a shorter LOS. METHODS: We retrospectively reviewed LOS based on day of the week the operation was performed. RESULTS: We reviewed 180 patients undergoing minimally invasive surgery with planned ostomy. Group 1 underwent surgery on Monday to Wednesday (n = 77), Group 2 on Thursday (n = 49), and Group 3 on Friday (n = 54). The average LOS for Group 1, 2, and 3 was 6.2, 4.9, and 7.2 days, respectively. The average number of visits with ostomy nursing for Group 1, 2, and 3 was 2.7, 1.8, and 2.3, respectively. Day of initial ostomy nursing visit was significantly correlated between the delay to initial visit and LOS with Group 3 delayed most. CONCLUSIONS: Patients with the longest delay to initial nurse visit had the longest LOS, with Friday operations being most delayed. A contributing factor may be absence of ostomy teaching over the weekend.

Alvimopan Use, Outcomes, and Costs: A Report from the Surgical Care and Outcomes Assessment Program Comparative Effectiveness Research Translation Network Collaborative.

BACKGROUND: Randomized trials have found that alvimopan hastens return of bowel function and reduces length of stay (LOS) by 1 day among patients undergoing colorectal surgery. However, its effectiveness in routine clinical practice and its impact on hospital costs remain uncertain. STUDY DESIGN: We performed a retrospective cohort study of patients undergoing elective colorectal surgery in Washington state (2009 to 2013) using data from a clinical registry (Surgical Care and Outcomes Assessment Program) linked to a statewide hospital discharge database (Comprehensive Hospital Abstract Reporting System). We used generalized estimating equations to evaluate the relationship between alvimopan and outcomes, and adjusted for patient, operative, and management characteristics. Hospital charges were converted to costs using hospital-specific charge to cost ratios, and were adjusted for inflation to 2013 US dollars. RESULTS: Among 14,781 patients undergoing elective colorectal surgery at 51 hospitals, 1,615 (11%) received alvimopan. Patients who received alvimopan had a LOS that was 1.8 days shorter (p < 0.01) and costs that were $2,017 lower (p < 0.01) compared with those who did not receive alvimopan. After adjustment, LOS was 0.9 days shorter (p < 0.01), and hospital costs were $636 lower (p = 0.02) among those receiving alvimopan compared with those who did not. CONCLUSIONS: When used in routine clinical practice, alvimopan was associated with a shorter LOS and limited but significant hospital cost savings. Both efficacy and effectiveness data support the use of alvimopan in routine clinical practice, and its use could be measured as a marker of higher quality care.

Screening, Surveillance, and Treatment of Anal Intraepithelial Neoplasia.

The prevalence of anal intraepithelial neoplasia has been increasing, especially in high-risk patients, including men who have sex with men, human immunodeficiency virus positive patients, and those who are immunosuppressed. Several studies with long-term follow-up have suggested that rate of progression from high-grade squamous intraepithelial lesions to invasive anal cancer is ∼ 5%. This number is considerably higher for those at high risk. Anal cytology has been used to attempt to screen high-risk patients for disease; however, it has been shown to have very little correlation to actual histology. Patients with lesions should undergo history and physical exam including digital rectal exam and standard anoscopy. High-resolution anoscopy can be considered as well, although it is of questionable time and cost-effectiveness. Nonoperative treatments include expectant surveillance and topical imiquimod or 5-fluorouracil. Operative therapies include wide local excision and targeted ablation with electrocautery, infrared coagulation, or cryotherapy. Recurrence rates remain high regardless of treatment delivered and surveillance is paramount, although optimal surveillance regimens have yet to be established.

Results from a novel modification to the ligation intersphincteric fistula tract.

BACKGROUND: The ligation of intersphincteric fistula tract (LIFT) procedure for trans-sphincteric fistula-in-ano has been studied with variable success rates compared with initial reports. Failures occur mostly in the intersphincteric wound. Recently, we proposed a modification to LIFT, unroofing the fistula from internal opening to intersphincteric groove, ligating the fistula tract, but preserving the external sphincter. METHODS: This retrospective review assesses outcomes of patients undergoing the modified LIFT for trans-sphincteric fistulae. RESULTS: Sixty-six modified LIFT procedures were performed. The main cohort consisted of 56 patients, predominantly men (76.7%). Median operative time was 16 minutes. Median follow-up was 20.98 weeks. Overall cure rate was 71.42%, with a recurrence rate of 5.35% and fistula persistence in 16.07%. There was no persistent fecal incontinence. CONCLUSION: Modified LIFT is a safe procedure that is easily performed, has short operative time, eliminates the intersphincteric space, and has cure rates equal to or better than the original LIFT.

Current treatment of lower gastrointestinal hemorrhage.

Massive lower gastrointestinal bleeding is a significant and expensive problem that requires methodical evaluation, management, and treatment. After initial resuscitation, care should be taken to localize the site of bleeding. Once localized, lesions can then be treated with endoscopic or angiographic interventions, reserving surgery for ongoing or recurrent bleeding.

Recent experience with abdominal perineal resection with vertical rectus abdominis myocutaneous flap reconstruction after preoperative pelvic radiation.

Abdominoperineal resection (APR) after pelvic radiation can be complicated by an increased rate of difficult to treat perineal wound complications. In an effort to improve postoperative morbidity after APR, myocutaneous flap reconstructions have been used. We review our recent experience with APR with vertical rectus abdominis myocutaneous flap reconstruction (VRAM) after preoperative pelvic radiation. A retrospective review of patients who underwent APR with VRAM reconstruction after pelvic radiation from December 2004 to July 2008 was conducted. Outcome measures included demographics, comorbidities, length of stay, wound complications, and morbidity and mortality. Fifteen patients with a mean age of 61 +/- 9 years underwent APR with VRAM reconstruction. Five patients also required posterior vaginectomy with the APR. Indications for APR were rectal cancer (n = 14, 93%) and anal canal cancer (n = 1, 7%). There were no intraoperative complications. Mean estimated blood loss was 635 +/- 446 mL and mean intraoperative blood transfusion requirements were 1 +/- 2 units. Mean length of hospital stay was 11 +/- 4 days. Six (40%) patients had minor perineal wound complications. One (7%) patient had a perineal wound infection requiring reoperation with washout and reapproximation. There was no 30-day or in-hospital mortality. All VRAM flaps remained viable through follow-up. APR with VRAM flap reconstruction after preoperative pelvic radiation can be performed safely with limited wound complications and no mortality.
