Predictive factors of surgery in metastatic colorectal cancer: a retrospective cohort study.

INTRODUCTION: Current management of metastatic colorectal cancer is based on neoadjuvant chemotherapy. Few studies have reported on surgery procedures in patients with metastatic colorectal cancer. The objective of this study was to describe our institutional experience with emergency surgery performed in patients with metastatic colorectal cancer during chemotherapy. PATIENTS AND METHODS: This was a retrospective cohort study including adult patients of ≤80 years with a metastatic colorectal cancer between 2017 and 2020 and undergoing surgery during chemotherapy. Statistical analyses were based on Kaplan-Meier's curve and Cox proportional hazard model. The surgery statistical risk during chemotherapy was studied through all tumor and patient's characteristics. Multivariable logistic regression models were used to identify predictive factors of emergency surgery in these patients. RESULTS: Seventy-two cases were identified and 60% patients undergone an emergency surgery. By Kaplan-Meier's analyses, intestinal surgery was much more frequent and early in patients who have severe stenosis (either blocking or only permeable using a gastroscope) at the time of diagnosis. Patients with severe malignant stenosis presented a 6.28 time higher surgery risk (p < .0001). The median time between admission and surgery was 54 days in patients with severe stenosis who were operated. CONCLUSION: The degree of colorectal tumor stenosis measured by endoscopy was a risk factor for emergency surgery in patients with metastatic colorectal cancer during neoadjuvant chemotherapy. In this group of patients presenting low survival outcomes, further studies are needed to define the place of preventive surgery, avoiding emergency surgery and morbidity in such fragile patients.

Perineal aggressive angiomyxoma in a menopausal woman.

Aggressive angiomyxoma (AA) is an uncommon mesenchymal tumour that is principally located in the soft tissues of the pelvis and perineum of young women. The primary features of this benign tumour are a local invasion, a high local recurrence rate and non-specific local clinical signs. We describe the case of a 58-year-old woman, initially treated for a Bartholin's cyst. Histological examination indicated the presence of an AA. The MRI showed a 7 cm soft tissue mass extending from the lateral wall of the vagina, into the left buttock and down into the subcutaneous tissue. We performed a radical excision with wide resection, which is considered the standard gold treatment.

Decision-making algorithm for the STARR procedure in obstructed defecation syndrome: position statement of the group of STARR Pioneers.

Internal rectal prolapse (rectal intussusception) and rectocele are frequent clinical findings in patients suffering from refractory constipation that may be best characterized as obstructive defecation syndrome. However, there is still no clear evidence whether the stapled transanal rectal resection (STARR) procedure provides a safe and effective surgical option for symptom resolution in patients with obstructive defecation syndrome, as evidence-based guidelines and functional long-term results are still missing. On the basis of the need for objective evaluation, a European group of experts was founded (Stapled Transanal Rectal Resection Pioneers). Derived from 2 meetings (October 26-28, 2006, Gouvieux, France and November 28-29, 2007, St Gallen, Switzerland) a concept for treatment options in patients suffering from obstructive defecation syndrome was developed, including a clear decision-making algorithm specifically focusing on the role of the stapled transanal rectal resection procedure based on clinical symptoms and dynamic imaging and inclusion and exclusion criteria for the stapled transanal rectal resection procedure.
