Introduction

The main objective of our study is to analyze the results in our hospital after launching a treatment protocol without antibiotic therapy for patients diagnosed with acute uncomplicated diverticulitis.

Methods

Our observational, prospective, single-center study was developed after launching a treatment protocol without antibiotic therapy for patients diagnosed with acute uncomplicated diverticulitis (AUD) in January 2021. The follow-up period was from January 1, 2021 to September 30, 2023. Variables evaluated by the study have included demographic and analytical variables, as well as those related to diagnosis and whether the patients needed to start antibiotic treatment, inpatient treatment, or surgical procedures.

Results

In total, 199 patients were diagnosed with AUD, 75 of whom were treated without antibiotic therapy as outpatients. Seven of these patients needed to start antibiotic treatment because of adverse evolution; none of these patients required surgical procedures. The need for inpatient treatment, urgent care, or surgical procedures is similar to the group of patients treated with antibiotics.

The main risk factor of failure of outpatient treatment without antibiotic therapy identified by the study was the presence of bacteriuria at diagnosis.

Conclusions

Our results confirm previous reports, observing that treatment without antibiotic therapy in selected patients with AUD is safe.

Introduction

The objective of the study is to compare 2 techniques for histological handling of rectal cancer specimens, namely whole-mount in a large block vs conventional sampling using small blocks, for mesorectal pathological assessment of circumferential resection margin status and depth of tumor invasion into the mesorectal fat.

Methods

This is a prospective study including 27 total mesorectal excision specimens of rectal cancer from patients treated for primary rectal carcinoma between 2020 and 2022 in a specialized multidisciplinary Colorectal Unit. For each total mesorectal excision specimen, 2 contiguous representative tumoral slices were selected and comparatively analyzed with whole-mount and small blocks macroscopic dissection techniques, enabling comparison between them in the same surgical specimen. The agreement between the 2 techniques to assess the distance of the tumor from the circumferential resection margin as well as the depth of tumor invasion was evaluated with the Student’s t-test for paired samples, Pearson’s correlation coefficient, and the Bland-Altman method comparison analysis.

Results

Complete mesorectal excision was observed in 8% of cases. Circumferential resection margin involvement was observed in only one case (4 %). The whole-mount and small block techniques obtained similar results when we assessed the distance to the circumferential resection margin (t-test P = 0.8, r = 0.92) and the depth of mesorectal infiltration (t-test P = 0.6, r = 0.95).

Conclusions

Both gross dissection techniques (whole-mount vs multiple small cassettes) are equivalent and reliable to assess the distance to circumferential resection margin and the depth of mesorectal infiltration in the mesorectal fat in rectal cancer staging.

In recent years, prehabilitation has generated high expectations as an innovative preoperative strategy to enhance clinical outcomes following surgery. Several studies have demonstrated that multimodal programs are effective in improving patients’ health status and cardiopulmonary reserve, allowing them to undergo surgery in better conditions and, consequently, reducing the incidence of postoperative complications.

Most publications describe proof-of-concept studies, and literature about their implementation is more limited. The implementation of these programs requires new resources and significant organizational effort.

In this paper, we share our experience implementing a multimodal prehabilitation program as a mainstream service at a tertiary hospital. Although there are still many unknowns regarding the optimal selection of patients, as well as the duration and components of the program, this article describes our journey in this field, aiming to provide insight for teams interested in developing a similar project.
