Adult intestinal malrotation: imaging findings.

Intestinal malrotation is the most common congenital anomaly of the small intestine. However, it is associated with delayed diagnosis due to the lack of specificity of its symptoms, which can lead to devastating consequences such as intestinal volvulus or massive intestinal necrosis. We present a clinical case in which we highlight the importance of abdominal computed tomography and the detection of its characteristic signs for the early identification of this pathology.

Resident training in colorectal laparoscopic surgery: A retrospective morbidity, mortality and survival analysis of 408 cases in our environment.

INTRODUCTION: Colorectal cancer has a growing incidence in our society. However, the performance of laparoscopic interventions in this field is still not included in the National Training Program. Given the lack of references, our objective was to analyze the resident's participation in laparoscopic colorectal surgery and its possible effect on morbidity and mortality and oncological prognosis. METHODS: A retrospective longitudinal single-center study that included all laparoscopic colorectal surgical procedures performed by residents (R group) and by attending surgeons (A group) between 01/01/2009 and 12/31/2017, maintaining follow-up until 12/31/2018. Postoperative morbidity and mortality, overall survival (OS) and disease- free survival (DFS), as well as their relationship with the resident involvement as first surgeon were analyzed. RESULTS: 408 patients were analyzed, of which 138 (33.8%) were operated by a supervised resident and 270 (66.2%) by the attending surgeon. No differences were detected in the rate of postoperative complications between both groups (OR: 1.536; 95% CI: 0.947-2.409; p = 0.081). Furthermore, resident participation had no influence on tumor recurrence rate (R Group: 14.2% vs. A Group: 16.9%; p = 0.588) or on overall (p = 0.562) or disease-free survival (p = 0.305). CONCLUSION: Resident involvement in laparoscopic colorectal surgery had no influence on morbidity and mortality or oncological prognosis in our center. Conducting prospective studies in this regard will provide greater knowledge, enabling a progressive improvement of the training program.

Upper gastrointestinal bleeding due to hepatic artery aneurysm: Case report and literature review.

INTRODUCTION: Aneurysm of the hepatic artery is most of the time a rare and asymptomatic pathology, but in case of complication it shows high morbidity and mortality requiring in many cases an urgent treatment. PRESENTATION OF CASE: A 92-year-old male presented at the emergency department with high gastrointestinal bleeding and abdominal pain. Gastroscopy showed a submucosal lesion with active bleeding that was controlled through this approach. The study was expanded with a CT angiogram and a complicated hepatic aneurysm with duodenal fistulization was observed. DISCUSSION: After reviewing the case, surgical treatment is proposed as the first option but it is rejected by the patient. Thus, aneurysm embolization with coils and thrombin is performed, without further complications. CONCLUSION: Selective embolization of the hepatic artery aneurysm is a therapeutic alternative in cases that implies large comorbidities, being an increasingly used technique.

[Use of pneumoperitoneum in the repair of giant abdominal hernias]. / Neumoperitoneo en el tratamiento de hernias gigantes.

The preoperative use of progressive pneumoperitoneum has been demonstrated to be safe and effective in the treatment of large hernias. The indications for this technique include massive hernias, hernias in patients with high surgical risk, and large recurrent hernias. We describe four patients in whom progressive pneumoperitoneum was carried out under local anesthesia and sedation between 1 and 3 weeks before surgery. All four hernias were closed with a preperitoneal mesh. Insufflation was performed on an inpatient basis in two patients and in the ambulatory setting in one. No postoperative complications were detected. No evidence of recurrence was found during follow-up (10 months-11 years).
