Idiopathic Myointimal Hyperplasia of the Mesenteric Veins: A Rare Imitator of Inflammatory Bowel Disease.

Idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) is a rare cause of chronic colonic ischemia characterized by intimal smooth muscle proliferation and luminal narrowing of the small to medium sized mesenteric veins. It predominantly affects the rectosigmoid colon in otherwise healthy, middle-aged males. Definitive diagnosis and treatment are surgical; however, patients are frequently misdiagnosed, which often results in a protracted clinical course. We describe a case of IMHMV presenting as left hemicolitis in a 53-year-old male, as well as the endoscopic, histopathologic, and radiographic findings that established the diagnosis.

Collection and Utilization of Patient-Reported Outcome Measures in a Colorectal Surgery Clinic.

INTRODUCTION: The routine collection of patient-reported outcome measures (PROMs) promises to improve patient care. However, in colorectal surgery, PROMs are uncommonly collected outside of clinical research studies and rarely used in clinical care. We designed and implemented a quality improvement project with the goals of routinely collecting PROMs and increasing the frequency that PROMs are utilized by colorectal surgeons in clinical practice. METHODS: This mixed-methods, quality improvement project was conducted in the colorectal surgery clinic of a tertiary academic medical center. Patients were administered up to five PROMs before each appointment. PROM completion rates were measured. Additionally, we performed two educational interventions to increase utilization of our electronic health record's PROM dashboard by colorectal surgeons. Utilization rates and attitudes toward the PROM dashboard were measured. RESULTS: Overall, patients completed 3600 of 3977 (90.9%) administered PROMs during the study period. At baseline, colorectal surgeons reviewed 6.7% of completed PROMs. After two educational interventions, this increased to 39.3% (P = 0.004). Colorectal surgeons also felt that the PROM dashboard was easier to use. Barriers to greater PROM dashboard utilization included poor user interface/user experience and a perceived lack of knowledge, time, and relevance. CONCLUSIONS: The collection of PROMs in colorectal surgery clinics is feasible and can result in high PROM completion rates. Educational interventions can improve the utilization of PROMs by colorectal surgeons in clinical practice. Our experience collecting PROMs through this quality improvement initiative can serve as a template for other colorectal surgery clinics interested in collecting and utilizing data from PROMs.

What's the magic number? Impact of time to initiation of treatment for rectal cancer.

BACKGROUND: National guidelines, including the National Accreditation Program for Rectal Cancer, recommend initiation of rectal cancer treatment within 60 days of diagnosis; however, the effect of timely treatment initiation on oncologic outcomes is unclear. The purpose of this study was to evaluate the impact on oncologic outcomes of initiation of rectal cancer treatment within 60 days of diagnosis. METHODS: This was a retrospective review of stage II/III rectal cancer patients performed using the United States Rectal Cancer Consortium, a collaboration of 6 academic medical centers. Patients with clinical stage II/III rectal cancer who underwent radical resection between January 1, 2010 and December 31, 2018 were included. The primary exposure was treatment initiation, defined as either resection or initiation of chemotherapy or chemoradiotherapy, within 60 days of diagnosis. The primary outcome was disease recurrence, and the secondary outcome was all-cause mortality. RESULTS: A total of 1,031 patients meeting inclusion criteria were included in the analysis. Treatment was initiated within 60 days of diagnosis in 830 patients (80.5%) and after 60 days in 201 patients (20.3%). In multivariable logistic regression, older age, non-White race, and residence greater than 100 miles from the treatment center were significantly associated with delay in treatment beyond 60 days. In survival analysis, 167 patients (16.2%) experienced recurrent disease, and 127 patients (12.3%) died of any cause. In an adjusted model accounting for pathologic staging, treatment sequence, distance to care, age, comorbidities, treatment center, and receipt of adjuvant chemotherapy, neither progression-free survival nor all-cause mortality was significantly associated with timely initiation of therapy with hazard ratios of 1.09 (0.70, 1.69) and 1.03 (0.63, 1.66), respectively. CONCLUSION: This study found no difference in oncologic outcomes with initiation of treatment beyond 60 days.

Surgical resection and survival outcomes in metastatic young adult colorectal cancer patients.

BACKGROUND: The incidence of colorectal cancer in adults younger than age 50 has increased with rates expected to continue to increase over the next decade. The objective of this study is to examine the survival benefit of surgical resection (primary and/or metastatic) versus palliative therapy in this patient population. METHODS: We identified 6708 young adults aged 18-45 years diagnosed with metastatic colorectal cancer (mCRC) from 2004 to 2015 from the SEER database. Overall survival (OS) was analyzed using Kaplan-Meier estimation, log rank test, and multivariate Cox proportional hazards model. RESULTS: Sixty-three percent of patients in our study underwent primary tumor resection (PTR), with 40% undergoing PTR alone and 23% undergoing both resection of primary disease and metastasectomy. The median OS for patients who underwent both PTR and metastasectomy was 36 months, compared to 13 months for those who did not receive any surgical intervention. The multivariate analysis showed significant OS benefit of receiving both PTR and metastasectomy (HR 0.34, 95% CI: 0.31-0.37, p < 0.001) compared to palliative therapy. Undergoing PTR only and metastasectomy only were also associated with improved OS (HR 0.46, 95% CI: 0.43-0.49, p < 0.001 and HR 0.64, 95% CI: 0.55-0.76, p < 0.001, respectively). CONCLUSION: This is the largest observational study to evaluate survival outcomes in young-onset mCRC patients and the role of surgical intervention of the primary and/or metastatic site. Our study provides evidence of statistically significant increase in OS for young mCRC patients who undergo surgical intervention of the primary and/or metastatic site.

A review of laparoscopy for non-obstetric-related surgery during pregnancy.

PURPOSE: Similar to the general population, parturients (and their fetuses) could benefit from the reduced manipulation associated with laparoscopy. The purpose of this article is to review the current state of knowledge (both clinical and experimental) with respect to the fetal effects of maternal laparoscopy for non-obstetric-related surgery during pregnancy. METHODS: Human and experimental animal results are examined, and we present preliminary data from our own laboratory. CONCLUSIONS: Future experiments are proposed to further develop and refine standards of care for general surgeons and obstetricians who are presented with gravid females in abdominal distress.
