Risk factors for local recurrence of rectal cancer after curative surgery: A single-center retrospective study.

Purpose: Approximately 7% of patients with rectal cancer experience local recurrence within 5 years of curative surgery. A positive circumferential resection margin (CRM) is among the most significant risk factors. Other reported risk factors include histopathologic type, anastomotic leakage, positive distal margins, and more recently, the anterior localization of the tumor.

Performance of a predictive weight loss model in terms of rapid detection of inadequate weight loss after Roux-en-Y gastric bypass.

Background: Predictive weight loss models can help patients meet their expectations after bariatric surgery and assist physicians in responding to deviations from the predicted weight. A model published by Seyssel et al. appears to accurately predict postoperative body mass index.

A 56-Year-Old Woman with Acute Cholecystitis and a Moynihan's Hump, or Caterpillar Configuration, of the Right Hepatic Artery Identified During Laparoscopic Cholecystectomy.

BACKGROUND When performing a cholecystectomy, several variations can be encountered by the surgeon. The "Moynihan's hump" or "caterpillar configuration" of the right hepatic artery are the terms used to describe a tortuous right hepatic artery running proximal or parallel to the cystic duct, resulting in a small or short cystic artery and occupying most of Calot's triangle. This report is of a 56-year-old woman with acute cholecystitis and a Moynihan's hump or caterpillar configuration identified at laparoscopic cholecystectomy.

Antiangiogenic Therapy as a New Strategy in the Treatment of Endometriosis? The First Case Report.

Angiogenesis plays a pivotal role in implantation and development of ectopic endometrial lesions. Thus, the potential usefulness of anti-angiogenic therapies has been speculated. Several reports describe their usefulness in animal models.

An effect of the COVID-19 pandemic: Significantly more complicated appendicitis due to delayed presentation of patients!

Aims Of The Study: The novel coronavirus pandemic has affected emergency department consultations for surgical pathologies. The aim of our study was to compare the number of acute appendicitis cases and the proportion of complicated appendicitis before and during the COVID-19 pandemic.

Methods: We retrospectively analyzed all data collected from a multi-center database of patients presenting to the emergency department for acute appendicitis during the COVID-19 pandemic from March 12 to June 6, 2020, and compared these data with those from the same periods in 2017, 2018, and 2019.

Perforated Meckel's Diverticulitis in a Patient with Unknown Intestinal Malrotation: Clinical Pitfall.

Symptomatic Meckel's diverticulum is rare in adults. The most frequent complications are intestinal obstruction and diverticulitis. Diagnosis of Meckel's diverticulitis can be challenging due to nonspecific clinical manifestation of pain in the right lower abdominal quadrant, mimicking acute appendicitis.

Giant gluteal lipoma surgical management.

Surgical treatment of lipomas is typically only considered when they are painful or unsightly. We present the case of a massive hip lipoma; with this extreme case, we show that the global prolongation of life expectancy can lead to other indications of removal.

Infrarenal Infected Aortic Aneurysm Caused by .

Infectious aneurysm is a rare entity associated with significant morbidity and mortality. Current knowledge on pathogenesis, outcome, diagnosis, management, and follow-up remains debatable. We report the case of a patient with aneurysm who was successfully treated with a homograft implant and discuss microbiological characteristics, diagnostic methods, and treatment options currently available for this serious disease.

A Rare Type of Colorectal Cancer: Mixed Adeno-Neuroendocrine Carcinoma (MANEC).

The aim of this paper is to report the clinicopathological data of one case of mixed metastatic adenoneuroendocrine carcinoma (MANEC) in the caecum; less than ten cases of which have been described in the English literature. A 57-year-old male patient presented with a mixed adenoneuroendocrine carcinoma (MANEC) of the caecum with liver metastasis and peritoneal carcinomatosis. An emergency right hemicolectomy and omentectomy were performed, followed by several cycles of unsuccessful palliative chemotherapy.

Contained rupture of a mycotic infrarenal aortic aneurysm infected with Campylobacter fetus.

Mycotic abdominal aortic aneurysms (MAAAs) are rare entities accounting for 0.65-2% of aortic aneurysms. Campylobacter fetus has a tropism for vascular tissue and is a rare cause of mycotic aneurysm.

Anterior Rectal Resection in a Patient with Aortoiliac Occlusive Disease and Coexisting Collateral Pathways: Management and Pitfalls.

Chronic aortoiliac occlusive disease most often affects the common iliac arteries and distal aorta but can progress all the way to the renal arteries, occluding the inferior mesenteric artery. A compensatory collateral network typically develops to preserve lower body perfusion. Inadvertent compression or ligation of such collaterals during surgery can have catastrophic consequences.

A Case of Gastro-Duodenal Artery Aneurism: Treatment and Complications.

We present the case of a 75-year-old patient with asymptomatic gastro-duodenal artery aneurism (GAA) that was coiled through the left femoral artery. The gastro-duodenal artery (GDA) was then embolized. Following the intervention, the patient'™s left foot became cold.

Urothelial Carcinoma Recurrence in an Ileal Neobladder Nine Years after Primary Surgery with Muir-Torre Syndrome.

We report a patient who presented with a urothelial carcinoma recurrence developed nine years after radical cystoprostatectomy, related to Muir-Torre syndrome.
