Recurrent intestinal intussusception in an adult due to intestinal pseudopolyps not associated with inflammatory bowel disease: a case report.

INTRODUCTION: Intestinal intussusception is very rare in adults and, unlike in children, it is due to an organic cause, mainly benign or malignant tumors, in 90 % of cases. Recurrent intussusception in an adult is even more exceptional, and in the case reported it was due to repeated occurrence of intestinal pseudopolyps, which is exceptional according to the literature. Preoperative diagnosis is difficult, and surgery is always indicated because a tumor is usually present. The surgical procedure may be controversial, as some would prefer desintussusception before resection, while others would advocate initial resection because of the risk of dissemination if a malignant lesion exists. CASE PRESENTATION: We report the case of a 34-year-old Caucasian man who underwent emergency laparoscopic surgery for intestinal obstruction and was found to have a jejunal intussusception. Polyps or pseudopolyps, some of them large and causing the intussusception, were seen in the surgical specimen. Our patient had also undergone surgery for intussusception 10 years before, after which the pathological report also noted the presence of these formations. CONCLUSIONS: Recurrent intussusception in adults due to the presence of intestinal pseudopolyps is exceptional and, to the best of our knowledge, this is the first such case reported.

[Acute abdomen caused by eosinophilic enteritis: six observations]. / Abdomen agudo causado por enteritis eosinofílica: a propósito de seis observaciones.

BACKGROUND: Eosinophilic enteritis is a rather rare condition characterized by infiltration of the gastrointestinal tract by eosinophils; as a casue of acute abdomen it is really exceptional. The etiology is unclear and its description in the literature is sparse, but associations have been made with collagen vascular disease, inflammatory bowel disease, food allergy and parasitic infections as it was confirmed in one of our pathologic studies. CLINICAL CASES: From 1997 to 2011 six cases of eosinophilic enteritis that involved a small bowel segment were diagnosed. A partial resection by an irreversible necrosis was necessary in three of them; in the other three only a biopsy was necessary due to the inflammatory aspect of the affected loop causing the acute abdomen. CONCLUSIONS: Eosinophilic enteritis can originate acute abdomen processes where an urgent surgical treatment is necessary. The intraoperative aspect can be from a segment of small bowel with inflammatory signs up to a completely irrecoverable loop, where removing of the affected segment is the correct treatment, which can be done laparoscopically.

Antecedentes: la enteritis eosinofílica es un padecimiento raro y los casos de abdomen agudo que origina suponen un mínimo porcentaje. Su etiología aún no está aclarada pero se asocia con enfermedades del colágeno, intolerancias alimentarias e infestaciones por parásitos, como anisakis, descubierto en una de las histologías de nuestros casos. Casos clínicos: de 1997 a 2011 se diagnosticaron seis casos de abdomen agudo; en tres de ellos la enteritis eosinofílica causó necrosis irreversible de un segmento intestinal y hubo que practicar una resección intestinal segmentaria. En dos de ellos había un segmento intestinal con aspecto inflamatorio, que fue el único hallazgo causante del cuadro agudo y en los que sólo se practicó biopsia y otro caso donde fue un hallazgo sin relación con el proceso agudo. Conclusiones: la enteritis eosinofílica puede ocasionar cuadros de abdomen agudo que requieren intervención quirúrgica urgente. El aspecto intraoperatorio es el de un segmento con aspecto inflamatorio que puede llegar a ser macroscópicamente irreversible y donde sólo la resección parcial es el tratamiento correcto, que puede hacerse por vía laparoscópica.

Estudio de casos y controles entre anastomosis intra y extracorpórea en pacientes intervenidos de hemicolectomía derecha laparoscópica / A case-control study of extracorporeal versus intracorporeal anastomosis in patients subjected to right laparoscopic hemicolectomy

IntroducciónEn la actualidad no existe suficiente evidencia científica sobre cuál es la mejor técnica para realizar la anastomosis -intracorpórea (IC) o extracorpórea (EC)- en la hemicolectomía derecha laparoscópica. El objetivo del presente estudio es determinar si existen diferencias al comparar ambas técnicas.Material y métodosSe realiza un estudio sobre una serie prospectiva de pacientes intervenidos en nuestro Centro mediante hemicolectomía derecha laparoscópica. Se comparan las variables preoperatorias, intraoperatorias y relacionadas con complicaciones recogidas en función del tipo de anastomosis.ResultadosDesde junio de 2004 hasta junio de 2010 se intervinieron 60 pacientes (35 IC; 25 EC). No existieron diferencias significativas entre ambos grupos en cuanto a características basales preoperatorias ni comorbilidades asociadas. La mediana de tiempo operatorio fue de 212 minutos (142-305min), sin diferencias significativas entre ambas técnicas. El número de ganglios extraídos resultó mayor en el grupo IC (21 versus 14; p=0,03). Tanto el inicio de la tolerancia oral como la primera deposición resultaron significativamente más precoces en el grupo IC. La tasa de complicaciones postoperatorias fue similar para ambos grupos (14% IC; 16% EC; p=0,89). Tres pacientes presentaron dehiscencia de anastomosis en las IC. La tasa de mortalidad fue del 2,8% (un paciente en cada grupo).ConclusiónLa anastomosis intracorpórea frente a la extracorpórea en la hemicolectomía derecha laparoscópica permite obtener un mayor número de ganglios resecados y un inicio más precoz de la tolerancia oral y del tránsito intestinal (AU)

IntroductionThere is still insufficient scientific evidence on which is the best technique to perform the anastomosis -intracorporeal (IC) or extracorporeal (EC)- in right laparoscopic hemicolectomy. The objective of the present study is to determine whether there are differences to compare in both techniques.Material and methodsA study was performed on a prospective patient series subjected to right laparoscopic hemicolectomy in our Hospital. The preoperative and the postoperative variables associated with complications recorded depending on the type of anastomosis.ResultsA total of 60 patients were intervened form June 2004 to June 2010 (35 IC; 25 EC). There were no significant differences between both groups as regards baseline preoperative characteristics or associated comorbidities. The median operation time was 212minutes (142-305min), with no significant difference between both techniques. The number of lymph nodes removed was higher in the IC group (21 versus 14; p=0.03). The beginning of oral tolerance and the first bowel movement were significantly earlier in the IC group. The complications rate was similar for both groups (14% IC; 16% EC; p=0.89). Three patients in the IC group had anastomosis dehiscence. The mortality rate was 2.8% (one patient in each group).ConclusionIntracorporeal versus extracorporeal anastomosis in right laparoscopic hemicolectomy can obtain a higher number of resected lymph nodes and an earlier oral tolerance and intestinal transit (AU)
