Comparative study using propensity score matching analysis in patients undergoing surgery for colorectal cancer with or without multimodal prehabilitation.

Introduction: The complication rate after major abdominal surgery is from 35 to 50%. The multimodal prehabilitation covers all the pre-operative problems to guarantee a faster recovery and reduce the rate of morbidity and mortality after a colorectal procedure.

Methods: Observational study, in patients with CRC who underwent surgical treatment between November 2020 and September 2022.

Polyp detection in the cecum and ascending colon by dye based chromoendoscopy - Is its routine use justified?

Introduction: colonoscopy is the best method for detecting polyps, with a reduction in colorectal cancer mortality of 29% and reaching 47% for distal tumors. However, it fails to demonstrate a significant reduction in proximal colon cancer mortality, and is the most common segment with interval neoplasm. The present study aimed to evaluate the impact on detection of polyps of a second sequential evaluation of cecum and ascending colon, with or without the use of indigo carmine chromoendoscopy.

Surgical treatment of rectal cancer: prospective cohort study about good oncologic results and low rates of abdominoperineal excision.

Objectives: the purpose of this study was to evaluate the outcome of rectal cancer surgery, in a unit adopting the principles of total mesorectal excision (TME) with a high restorative procedure rate and with a low rate of abdominoperineal excision (APE).

Methods: we enrolles patients with extraperitoneal rectal cancer undergoing TME or TME+APE. Patients with mid rectal tumors underwent TME, and patients with tumors of the lower rectum and no criteria for APE underwent TME and intersphincteric resection.

Conditions associated with worse acceptance of a simplified accelerated recovery after surgery protocol in laparoscopic colorectal surgery.

Background: Enhanced Recovery Surgical Programs were initially applied to colorectal procedures and used as multimodal approach to relieve the response to surgical stress. An important factor that negatively impacts the success of these programs is the poor tolerance of these patients to certain items in the adopted protocol, especially with regard to post-operative measures. The identification of these factors may help to increase the success rate of such programs, ensuring that benefits reach a greater number of patients and that resources are better allocated.

The applicability of POSSUM and P-POSSUM scores as predictors of morbidity and mortality in colorectal surgery.

Objective: to apply the POSSUM and P-POSSUM scores as a tool to predict morbidity and mortality in colorectal surgery.

Methods: we conducted a prospective cohort study of 551 patients submitted to colorectal surgery in a colorectal surgery tertiary referral hospital in Brazil. We grouped patients into pre-established risk categories for comparison between expected and observed morbidity and mortality rates by the POSSUM and P-POSSUM scores.

Male sexual function after total mesorectal excision: a comparison between laparoscopic and open surgery during the learning curve period.

Introduction: This study assessed male sexual function using a specific and validated questionnaire, the International Index of Erectile Function (IIEF), in patients subjected to open total mesorectal excision (OTME) and laparoscopic total mesorectal excision (LTME) and compared it with a control group.

Patients And Methods: The inclusion criteria consisted of male patients with an active sexual life before surgery subjected to OTME or LTME at the Coloproctological Unit of the Clinics Hospital, Minas Gerais Federal University, between January 2005 and September 2009. The IIEF questionnaire was used.

Assessment of postoperative pain and hospital discharge after inguinal and iliohypogastric nerve block for inguinal hernia repair under spinal anesthesia: a prospective study.

Objective: This study was designed to evaluate analgesia (pain intensity and analgesic consumption) and the time of discharge of patients who underwent ilioinguinal (II) and iliohypogastric (IH) nerve block associated with wound infiltration with 0.75% ropivacaine, or not, after inguinal hernia repair surgery under spinal anesthesia.

Methods: This was a prospective, randomized, double-blind study with 34 patients undergoing inguinal hernia repair.
