RESUMEN
Fecal ostomy creation is a commonly performed procedure with many indications. Better outcomes occur when preoperative patient education and stoma site marking are provided. Despite a seemingly simple operation, ostomy creation is often difficult and complications are common. Certain risk factors, particularly obesity, are strongly associated with stoma-related complications. The ability to optimize the ostomy and stoma in the operating room and to troubleshoot frequently encountered post-operative stoma-related issues are critical skills for surgeons and ostomy nurses alike.

Colonic diverticulosis is pervasive in Western society, with over half of individuals over the age of 60 carrying the diagnosis. A Giant Colonic Diverticulum (GCD) is a rare presentation of diverticulosis, involving one or more colonic diverticula that measure 4 cm or greater. Less than 200 reports of GCD have been published in the literature. Almost all GCD patients present with symptoms, with abdominal pain being the most common. Diagnosis is usually made with CT imaging and recommended treatment is segmental colectomy. We present an atypical case of GCD with an asymptomatic presentation, initial diagnosis made during endoscopy and a minimally invasive resection of multiple GCD within the same patient.
RESUMEN
BACKGROUND: Current guidelines recommend considering adjuvant chemotherapy (AC) for stage II colon cancer (CC) with poor prognostic clinicopathologic and molecular features. However, the relative impact of individual or constellations of high-risk features remains undefined. We developed an individualized point-of-care tool to predict survival benefit attained from the addition of AC. METHODS: The National Cancer Database was queried for all patients with resected stage II CC from 2004 to 2015. A prognostic risk score and nomogram were constructed using twelve clinicopathologic and molecular prognostic factors associated with outcomes for CC. Overall survival (OS) was compared between surgery alone and AC groups. The nomogram was validated for discrimination and calibration using bootstrap-adjusted Harrell's concordance index (C-index). For population-level estimation, OS was compared based on quartiles. RESULTS: Of 132,666 patients with stage II CC, 16.8% received AC. The calibration curve of the constructed nomogram showed a good agreement between predicted and observed median and 3-, 5-, and 10-year survival (bootstrap-adjusted C-index 0.699, CI: 0.698-0.703). Population-level risk score analysis (median [Q1, Q3]; 4.9 [4.6, 5.5]) demonstrated that patients with scores > 3.34 had significantly decreased risk of death with the addition of AC (all p < 0.001). No survival advantage was associated with AC among patients with low risk scores (risk score < 3.34: HR: 0.94, 95% CI: 0.80-1.11, p = 0.47). DISCUSSION: A composite weighted risk score is critical to individualizing AC in select high-risk patients. Our nomogram provides individualized prognostication and estimation of benefit attained from AC. This may better inform treatment decisions and aid future trial design.

A patient presented to the emergency department with undifferentiated shock 4 days after discharge from a hospitalization for a lower gastrointestinal bleed. The patient fulfilled 4/4 of the Systemic Inflammatory Response Syndrome criteria and 3/3 of the quick Sequential Organ Failure Assessment criteria on presentation to the emergency department, notably, without a localized source of infection and no localizing symptoms. After admission, the patient's hemoglobin was found to have dropped more than expected after intravenous (IV) fluid administration, suggesting a potential alternative or concurrent etiology of the patient's shock state. A digital rectal and focused assessment with sonography in trauma exam were performed and negative. The patient was then diagnosed with a ruptured infrarenal abdominal aortic aneurysm contained in the retroperitoneum by repeat point-of-care ultrasound. The patient was hemodynamically stabilized and taken for emergent grafting without confirmatory imaging. The patient was later found to also have 4/4 blood cultures positive with methicillin-sensitive Staphylococcus aureus associated with an aortic valvular vegetation and a mycotic aneurysm which contributed to the abdominal aortic aneurysm rupture. This case supports the use of comprehensive point-of-care ultrasound imaging to more rapidly and more definitively differentiate types of shock and etiologies of a shock state which can lead to more timely changes in management and improvement in outcomes.

BACKGROUND: Despite a lack of supporting data, routine splenic flexure mobilization (SFM) during colectomy has been thought to reduce anastomotic leak (AL). We evaluated the impact of SFM on outcomes in distal colectomy. STUDY DESIGN: The 2005-2016 NSQIP database identified 66,068 patients undergoing distal colectomy with anastomosis. Cohorts were stratified by addition of SFM. Postoperative outcomes were compared between groups. Regression analysis identified factors affecting odds of developing AL. RESULTS: SFM was performed in 27,475 patients (41.6%). There was no difference in overall complications between cases with SFM and those without (pâ¯=â¯0.55). SFM had longer operative times (220â¯min vs. 184 min; pâ¯<â¯0.0001). SFM was not associated with any difference in AL rate (3.6% vs. 3.7%; pâ¯=â¯0.86). Factors most associated with AL were lack of oral antibiotic preparation (OR 1.93; pâ¯<â¯0.001), chemotherapy (OR 1.91; pâ¯<â¯0.001), and weight loss (OR 1.68; pâ¯=â¯0.0005). Operative indication and approach did not affect leak. CONCLUSIONS: SFM in distal colectomy increased operative time without decreasing overall complications or AL. Routine splenic flexure mobilization may add risk without significant benefit.
