Introduction

Virtual reality (VR) provides a firsthand active learning experience through varying degrees of immersion. The aim of this study is to evaluate the use of VR as a potential tool for training operating room nurses to perform thoracic surgery procedures.

Methods

This is an open parallel-group randomized clinical trial. One group received basic formation followed by an assessment module. The experimental group received the same basic formation, followed by thoracic surgery training and an assessment module.

Results

Fifty-six nurses participated in the study (51 females), with a mean age of 41.6 years. Participants achieved a median evaluation mode score of 480 points (IQR = 32 points). The experimental group (520 points) achieved an overall higher score than the control group (440 points; P = .04). Regarding age, women in the second quartile of age among the participants (35–41 years) achieved significantly better results than the rest (P = .04). When we evaluated the results based on the moment of practice, exercises performed in the last 10 min obtained better results than those performed in the first 10 min (1064 points versus 554 points; P < .001). Regarding adverse effects blurred vision was the most frequent. The overall satisfaction rating with the experience was 8.5 out of 10.

Conclusion

Virtual reality is a useful tool for training operating room nurses. Clinical trial with ISRCTN16864726 registered number.

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.

There is no international consensus on the definition of the type of oncological resection that corresponds to each of the colectomies existing in the current literature.

The objective is to define for each colectomy described in the literature: embryological dissection plane, vascular pedicles in which to perform central ligation, the extent of the colectomy, and the need for resection of the greater momentum.

A consensus of experts is carried out through the Delphi methodology through two rounds from the Coloproctology Section of the Spanish Association of Surgeons. Study period: November 2021-January 2023. 120 experts were surveyed.

Degrees of consensus: Very strong: >90%, Strong: 80%–90%, Moderate: 50%–80%, No consensus: <50%.

The definition for each oncological colectomy was established by very strong, and strong recommendations.

Each oncological colectomy was established as Right hemicolectomy (RHC), RHC with D3 lymphadenectomy, Extended-RHC, transverse colon segmental colectomy, splenic flexure segmental colectomy, subtotal colectomy, total colectomy, left hemicolectomy (LHC), extended-LHC, sigmoidectomy.

Introduction

Local resection (LR) is an alternative to total mesorectal excision (TME) that avoids its associated morbidity to the detriment of oncological radicality in early stages of rectal cancer. There are several conditioning factors for the success of this strategy, such as poor prognosis histological factors (PPHF), involvement of resection margins, clinical under staging, or complications that may lead to the indication for radical surgery with TME.

Patients and method

An international multicenter prospective observational open-label study has been designed. Consecutive patients diagnosed with early rectal cancer (cT1N0 on MRI +/− endorectal ultrasound) whose lower limit is a maximum of 2 cm proximal to the ano-rectal junction will be included. The primary objective of the study is to determine the overall prevalence of PPHF after LR and requiring TME or postoperative radio-chemotherapy.

Discussion

The prevalence of PPHF conditioning the success of LR in early distal rectal cancer has been scarcely studied in the literature, and there are very few prospective data. Considering the increasing interest in the watch and wait strategy in rectal cancer and its possible application in early-stage tumors, it seems necessary to know this information.

The results of this study will help guide clinical practice in patients with early distal rectal cancer. It will also provide quality information for the design of future comparative studies to improve organ preservation success in these patients.
