Risk Factors for Rectal Cancer Recurrence after Local Excision of T1 Lesions from a Decade-Long Multicenter Retrospective Study.

Local surgical excision of T1 rectal adenocarcinoma is a well-established approach. Yet, there are still open questions regarding the recurrence rates and its risk factors. A retrospective multicenter study including all patients who underwent local excision of early rectal cancer with an open or MIS approach and had a T1 lesion from 2010 to 2020 in six academic centers.

Rectal Cancer following Local Excision of Rectal Adenomas with Low-Grade Dysplasia-A Multicenter Study.

: Rectal polyps with low-grade dysplasia (LGD) can be removed by local excision surgery (LE). It is unclear whether these lesions pose a higher risk for recurrence and cancer development and might warrant an early repeat rectal endoscopy. This study aims to assess the rectal cancer rate following local excision of LGD rectal lesions.

Initial Experience with Transition from Open to Robotic-assisted Proctectomy for Patients with Rectal Cancer.

Background: The learning curve for transition from open to laparoscopic proctectomies is difficult. Most surgeons have considerable laparoscopic experience prior to performing robotic-assisted procedures. There are data regarding the transition from open to robotic proctectomies.

Intratumoral HLA-DR/CD33/CD11b Myeloid-Derived Suppressor Cells Predict Response to Neoadjuvant Chemoradiotherapy in Locally Advanced Rectal Cancer.

Capecitabine-based neoadjuvant chemoradiation therapy (nCRT) is currently the mainstay of treatment for locally advanced rectal cancer (LARC), prior to surgical tumor removal. While response to this treatment is partial, it carries significant risk of side effects. As of today, there is no accepted model to predict tumor response, and allow for patient stratification.

[EDUCATION OF RESIDENTS AND SURGICAL SKILLS ASSESSMENT IN THE OPERATING THEATRE].

Competence based surgical education is gaining acceptance in many residency programs around the world. Changing and fluctuating working hours for residents, the need for vast knowledge acquisition during residency, as well as the application of new emerging technologies in surgical practices, call for the modification of educational platforms and domains in surgical teaching. Milestones of cognitive knowledge, as well as surgical and other essential skills needed for the "formation" of a competent resident are judiciously laid during the residency process.

Transanal Endoscopic Microsurgery Implementation in Ultra-Low Anterior Resection.

Background: Distal rectal cancer resection is an ongoing challenge for the colorectal surgeon. In recent years new technical approaches, especially with implementation of transanal platforms were developed to help in the visualization and resection of these tumors. Nevertheless, the use of these platforms is demanding with significant complications during the onset phase.

Laparoscopic diagnostic peritoneal lavage (L-DPL): A method for evaluation of penetrating abdominal stab wounds.

Background: The management of penetrating abdominal stab wounds has been the subject of continued reappraisal and controversy. In the present study a novel method which combines the use of diagnostic laparoscopy and DPL, termed laparoscopic diagnostic peritoneal lavage (L-DPL) is described

Method: Five trauma patients with penetrating injuries to the lower chest or abdomen were included. Standard videoscopic equipment is utilized for the laparoscopic trauma evaluation of the injured patient.
