Long-term results of a prospective randomized trial of midline laparotomy closure with onlay mesh.

PURPOSE: Incisional hernia (IH) continues to be one of the most common complications of laparotomy. The short-term protective effect of the use of mesh has been demonstrated in several studies. At present, there is little evidence on the long-term results of the prophylactic use of mesh. The aim of the present study is to analyze the long-term prevention of IH 5 years after a midline laparotomy during elective surgery. METHODS: A prospective study was performed including all of the 160 patients that had been previously included in the prospective, randomized, controlled trial performed between May 2009 and November 2012. The protocol and results at 1 year have been previously published in 2014. The patients in group A (mesh) were fitted with a polypropylene mesh to reinforce the standard abdominal wall closure. The patients in group B (non-mesh) underwent a standard abdominal wall closure and were not fitted with the mesh. All patients were followed for 5 years or until the diagnosis of incisional hernia was made, further surgery was performed, or the patient died. Cases lost to follow-up were also registered. RESULTS: Five years after surgery, in group A (mesh) we have found 4/80 (5.1%) incisional hernias, while in group B (no mesh) 37/80 patients were diagnosed with an incisional hernia (46.8%). The Kaplan-Meier survival curves for these results show statistically significant differences (p > 0.001). CONCLUSION: The protective effect of the use of an onlay mesh in abdominal wall closure is significantly maintained in the long-term, up to 5 years after surgery.

Malrotación-vólvulo intestinal: hallazgos radiológicos / Intestinal malrotation - volvulus: imaging findings

El radiólogo debe ser capaz de reconocer los signos de la malrotación intestinal en la imagen al tratarse de una entidad patológica con complicaciones potencialmente letales, como el vólvulo de intestino medio. Para diagnosticarla correctamente, es tan importante que exista un índice de sospecha clínica elevado como que el radiólogo sepa reconocer los signos específicos de malrotación y las variantes de la normalidad que pueden conducir a un diagnóstico erróneo. Aunque la posición no retroperitoneal de la tercera porción duodenal en ecografía, TC o RM parece ser un signo fiable para el diagnóstico, el tránsito gastrointestinal continúa siendo el estándar de referencia para ver la unión duodeno-yeyunal en una posición anómala. Nuestro objetivo es revisar los principales signos radiológicos de esta enfermedad y hacer hincapié en el papel de la ecografía para diagnosticar el vólvulo de intestino medio (AU)

Radiologists must be able to recognize the imaging signs of intestinal malrotation because this condition can lead to potentially lethal complications such as midgut volvulus. The correct diagnosis depends on both high clinical suspicion and the radiologist's ability to recognize the specific signs of malrotation and the normal variants that can lead to the wrong diagnosis. Although the location of the third portion of the duodenum outside the retroperitoneal area on ultrasonography, CT, or MRI seems to be a reliable sign of malrotation, the gold standard for determining whether the duodenojejunal flexure is in an abnormal location continues to be the upper gastrointestinal series. In this article, we review the most important imaging signs of malrotation and emphasize the role of ultrasonography in diagnosing midgut volvulus (AU)

Prevention of incisional hernia in midline laparotomy with an onlay mesh: a randomized clinical trial.

OBJECTIVE: Our objective was to evaluate the prevention of incisional hernia (IH) during the postoperative period of a midline laparotomy during elective surgery. MATERIAL AND METHODS: A controlled, prospective, randomized, and blind study was carried out. The patients in group A (mesh) were fitted with a polypropylene mesh, to reinforce the standard abdominal wall closure. The patients in group B (non-mesh) underwent a standard abdominal wall closure and were not fitted with the mesh. RESULTS: In group A, 2/80 his were diagnosed, whereas in group B the number was 30/80. The Kaplan-Meier survival curves show that the likelihood of IH at 12 months is 1.5 % in group A compared with 35.9 % in group B (p < 0.0001), which means that the differences are statistically significant. CONCLUSION: Fitting a prophylactic supra-aponeurotic mesh prevents IH independently of other factors.
