Full-text for Emory users.

Results: After randomization, 12 patients were excluded. Accordingly, 240 patients were included in the analysis; 118 were in the study group, and 122 in the control group. ICG angiography showed insufficient perfusion of the colic stump, which led to extended bowel resection in 13 cases (11%). An anastomotic leak developed in 11 patients (9%) in the control group and in 6 patients (5%) in the study group (p = n.s.).

Conclusions: Intraoperative ICG fluorescent angiography can effectively assess vascularization of the colic stump and anastomosis in patients undergoing colorectal resection. This method led to further proximal bowel resection in 13 cases, however, there was no statistically significant reduction of anastomotic leak rate in the ICG arm.

ASCRS Clinical Practice Guidelines for the Treatment of Left-Sided Colonic Diverticulitis

Hall J, Hardiman K, Lee S, et al. The American Society of Colon and Rectal Surgeons Clinical Practice Guidelines for the Treatment of Left-Sided Colonic Diverticulitis. Dis Colon Rectum. 2020 Jun;63(6):728-747.

Full-text for Emory users.

“This publication summarizes the changing treatment paradigm for patients with left-sided diverticulitis. Although diverticular disease can affect any segment of the large intestine, we will focus on left-sided disease. Bowel preparation, enhanced recovery pathways, and prevention of thromboembolic disease, while relevant to the management of patients with diverticulitis, are beyond the scope of these guidelines and are addressed in other ASCRS clinical practice guidelines.”

The surgical management of purulent peritonitis from perforated diverticulitis

Oberkofler CE, et al. A multicenter randomized clinical trial of primary anastomosis or Hartmann’s procedure for perforated left colonic diverticulitis with purulent or fecal peritonitis. Ann Surg. 2012 Nov; 256(5):819-26; discussion 826-7.

Full-text for Emory users.

Results: Patient demographics were equally distributed in both groups (Hinchey III: 76% vs 75% and Hinchey IV: 24% vs 25%, for HP vs PA, respectively). The overall complication rate for both resection and stoma reversal operations was comparable (80% vs 84%, P = 0.813). Although the outcome after the initial colon resection did not show any significant differences (mortality 13% vs 9% and morbidity 67% vs 75% in HP vs PA), the stoma reversal rate after PA with diverting ileostomy was higher (90% vs 57%, P = 0.005) and serious complications (Grades IIIb-IV: 0% vs 20%, P = 0.046), operating time (73 minutes vs 183 minutes, P < 0.001), hospital stay (6 days vs 9 days, P = 0.016), and lower in-hospital costs (US $16,717 vs US $24,014) were significantly reduced in the PA group.

Conclusions: This is the first randomized clinical trial favoring PA with diverting ileostomy over HP in patients with perforated diverticulitis.

Full-text for Emory users.

Objective: To assess potentially modifiable perioperative risk factors for anastomotic leakage in adult patients undergoing colorectal surgery.

Summary background data: Colorectal anastomotic leakage (CAL) is the single most important denominator of postoperative outcome after colorectal surgery. To lower the risk of CAL, the current research focused on the association of potentially modifiable risk factors, both surgical and anesthesiological.

Ureteral catheters and injury during colectomy: A NSQIP study

One discussion this week included ureteral injuries during colectomy.

Reference: Coakley KM, et al. Prophylactic ureteral catheters for colectomy: A National Surgical Quality Improvement Program-based analysis. Diseases of the Colon and Rectum. 2018 Jan;61(1):84-88. doi:10.1097/DCR.0000000000000976.

Summary: Despite improvement in technique and technology, using prophylactic ureteral catheters to avoid iatrogenic ureteral injury during colectomy remains controversial. The aim of this retrospective study was to evaluate outcomes and costs attributable to prophylactic ureteral catheters with colectomy. Conducted at a signle tertiary care center, the authors pulled clinical data, 2012-2014, from ACS NSQIP database.

A total of 51,125 patients were identified with a mean age of 60.9 ± 14.9 years and a BMI of 28.4 ± 6.7 k/m; 4.90% (n = 2486) of colectomies were performed with prophylactic catheters, and 333 ureteral injuries (0.65%) were identified.

  • Prophylactic ureteral catheters were most commonly used for diverticular disease (42.2%; n = 1048), with injury occurring most often during colectomy for diverticular disease (36.0%; n = 120).
  • Univariate analysis of outcomes demonstrated higher rates of ileus, wound infection, urinary tract infection, urinary tract infection as reason for readmission, superficial site infection, and 30-day readmission in patients with prophylactic ureteral catheter placement.
  • On multivariate analysis, prophylactic ureteral catheter placement was associated with a lower rate of ureteral injury (OR = 0.45 (95% CI, 0.25-0.81)).
  • Additional research is needed to delineate patient populations most likely to benefit from prophylactic ureteral stent placement.

Simultaneous vs staged colorectal and hepatic resections

One discussion this week involved the comparison of simultaneous and staged resections of colorectal cancer and synchronous colorectal liver metastases (SCRLM).

Summary: In a retrospective study of 610 patients at three institutions between 1985 and 2006, the authors compared postoperative morbidity and mortality after simultaneous and staged resections of colorectal cancer and SCRLM.
