Retroperitoneal and iliopsoas abscess as Crohn's disease onset mimicking a common lumbosciatic pain.

Crohn's Disease (CD) refers to a chronic transmural bowel inflammation affecting a range between 5 and 15 per 100,000 person-years worldwide 1. In patients with stricturing CD, the transmural pattern of inflammation may trigger the development of sinus tracts able to connect to other tissues, leading to the formation of fistulas or abscesses 2. Intra-psoas abscesses are rare, affecting between 0.

Rivaroxaban vs placebo for extended antithrombotic prophylaxis after laparoscopic surgery for colorectal cancer.

The clinical benefit of extended prophylaxis for venous thromboembolism (VTE) after laparoscopic surgery for cancer is unclear. The efficacy and safety of direct oral anticoagulants for this indication are unexplored. PROphylaxis of venous thromboembolism after LAParoscopic Surgery for colorectal cancer Study II (PROLAPS II) was a randomized, double-blind, placebo-controlled, investigator-initiated, superiority study aimed at assessing the efficacy and safety of extended prophylaxis with rivaroxaban after laparoscopic surgery for colorectal cancer.

A rare finding of Actinomyces odontolyticus abdominal actinomycosis presenting as abdominal wall and pericolic pseudotumoral mass.

Abdominal actinomycosis refers to a rare chronic suppurative infectious occurrence, caused by filamentous Gram-positive microaerophilic and anaerobic bacteria Actinomyces, that may appear as an abdominal mass and/or abscess, feasibly mimicking a malignancy 1,2. Due to its rarity and unspecific clinical evidence, the majority of cases are diagnosed after tissue specimen. We hereby report a case of a 69-year-old patient with a one week worsening abdominal pain and swelling.

An extremely rare finding of goblet cell carcinoid of the appendix. A case report.

Goblet cell carcinoid or carcinoma (GCC) refers to an extremely rare appendiceal tumor usually diagnosed on post-operative histology as an incidental finding. Primary cancers of the vermiform appendix are quite rare, representing less than 1% of all gastrointestinal malignancies. GCCs are considered as a distinct entity of appendiceal tumors, consisting of both epithelial (glandular) and neuroendocrine elements containing goblet cells.

Rivaroxaban for extended antithrombotic prophylaxis after laparoscopic surgery for colorectal cancer. Design of the PRO-LAPS II STUDY.

Background: The clinical benefit of extending prophylaxis for venous thromboembolism (VTE) beyond hospital discharge after laparoscopic surgery for cancer is undefined. Extended prophylaxis with rivaroxaban is effective in reducing post-operative VTE after major orthopedic surgery without safety concern.

Methods: PROLAPS II is an investigator-initiated, randomized, double-blind study aimed at assessing the efficacy and safety of extended antithrombotic prophylaxis with rivaroxaban compared with placebo after laparoscopic surgery for colorectal cancer in patients who had received antithrombotic prophylaxis with low molecular-weight heparin for 7 ± 2 days (NCT03055026).

A randomized study on 1-week versus 4-week prophylaxis for venous thromboembolism after laparoscopic surgery for colorectal cancer.

Objective: To compare the efficacy and safety of antithrombotic prophylaxis given for 1 week or 4 weeks in patients undergoing laparoscopic surgery for colorectal cancer.

Background: Extending antithrombotic prophylaxis beyond 1 week reduces the incidence of venous thromboembolism (VTE) after open abdominal surgery for cancer.

Methods: In consecutive patients who underwent laparoscopic surgery for colorectal cancer, complete compression ultrasonography of the lower limbs was performed after 8 ± 2 days of antithrombotic prophylaxis.
