Particular aspects of treating rectal cancer: The watch and wait approach.

Background: Rectal cancer is one of the most common malignant pathologies worldwide. Currently, the standard treatment of this pathology consists of radio-chemotherapy followed by low anterior resection with total mesorectal excision or abdominoperineal proctectomy for medium/low rectal cancer. Objectives: In recent years, another treatment strategy has been proposed, stemming from the finding that up to 40% of patients receiving neoadjuvant treatment had a complete pathological response. This method, also referred to as the watch and wait approach, implies delaying surgery and following a rigorous protocol for patients who have developed a complete response to neoadjuvant treatment with a good oncologic outcome. The objective of this study was to highlight the merits of this approach in selected patients. Case Reports: In this study, we present two patients with low-rectal tumors who developed complete response post neoadjuvant therapy and for whom the watch and wait protocol has been applied over the past 4 years. Conclusion: Although the watch and wait protocol appears to be a feasible option in the management of patients with a complete clinical and pathological response post neoadjuvant therapy, more prospective studies and randomized trials comparing this approach with standard surgical treatment are required before establishing it as the standard of care for distal rectal cancer. Therefore, establishing universal criteria for the selection and assessment of the patients with a complete clinical response following neoadjuvant treatment is required.

Posttraumatic Injury Polymorphism - The Experience of an Emergency Surgical Department During 5 Years.

Introduction: Traumatic injuries are a major public health problem, being one of the main causes of death, the subsequent decline in the quality of life of the patients involved, as well as the costs of hospitalization in the health system. Material and Method: We conducted a 5-year retrospective study on 798 hospitalized patients with traumatic injuries, by collecting a series of general, clinical, imaging and biological parameters. Results: The results showed a higher proportion of male patients, the main lesion mechanism being represented by road accidents, followed by falls from another level. The most common traumatic intraabdominal parenchymal lesions were splenic, followed by hepatic and renal lesions. In addition to intraabdominal trauma, the lesion balance also included thoracic, spinal cord, head and limb injuries. A total of 288 patients underwent emergency surgery, but there were also cases of delayed surgical procedures or reoperations. We had 67 deceased patients. Conclusions: Trauma is a major public health problem, both socially and economically, being responsible for a significant number of deaths, but also in terms of the significant number of hospitalizations and the subsequent impact on the quality of life of those involved.

Traumatic Diaphragmatic Lesions - Considerations Over a Series of 15 Consecutive Cases.

Introduction: Diaphragmatic injuries are produced by blunt or penetrating thoracoabdominal trauma. They are potentially life-threatening due to the herniation of abdominal organs into the pleural cavities and severe associated lesions. The aim of this retrospective study was to analyse the clinical presentation and management of patients admitted with diaphragmatic rupture in our institution. Material and Method: We performed a 5-year retrospective study of patients admitted with acute blunt or penetrating diaphragmatic rupture in the Department of General Surgery of "Bagdasar- Arseni" Emergency Hospital. We have studied sex, age, mechanism of trauma, side-location, timeto-diagnosis, concomitant injuries, surgical treatment and outcome. Results: Fifteen patients (8 males, 7 females, mean age: 42 years) with diaphragmatic rupture (left-side: 13, right-side: 2) following blunt (8 patients) or penetrating (7) trauma were included. Patients with blunt diaphragmatic injury had larger tears and abdominal viscera herniation was observed in 6of these cases. A direct suture was performed for all 15 patients. Laparotomy was the surgical approach preferred in most of the cases. Mortality rate was 20%, mainly caused by severe associated lesions. Conclusion: Although traumatic diaphragmatic lesions are frequently associated with severe cerebral and thoraco-abdominal trauma that is also the main cause of death, a prompt diagnosis and treatment can lead to good outcome.
