Prevention of parastomal hernia with a preperitoneal polypropelene mesh.

OBJECTIVE: To show our results with the use of a polypropylene mesh at the stoma site, as prophylaxis of parastomal hernias in patients with rectal cancer when a terminal colostomy is performed. METHODS: From January 2010 until March 2014, 45 consecutive patients with rectal cancer, underwent surgical treatment with the need of a terminal colostomy. A prophylactic mesh was placed in a sublay position at the stoma site in all cases. We analyze Demographics, technical issues and effectiveness of the procedure, as well as subsequent complications. RESULTS: A prophylactic mesh was placed in 45 patients, 35 male and 10 females, mean age of 66.2 (47-88) and Body Mass Index 29.19 (20.4-40.6). A total of 7 middle rectal carcinoma, 36 low rectal carcinoma, one rectal melanoma and one squamous cell anal carcinoma were electively treated with identical protocol. Abdominoperineal resection was performed in 38 patients, and low anterior resection with terminal colostomy in 7. An open approach was elected in 39 patients and laparoscopy in 6, with 2 conversions to open surgery. Medium follow up was 22 months (2.1-53). Overall, 3 parastomal hernias (6.66%) were found, one of which was a radiological finding with no clinical significance. No complications related to the mesh or the colostomy were found. CONCLUSIONS: The use of a prophylactic polypropylene mesh placed in a sublay position at the stoma site is a safe and feasible technique. It lowers the incidence of parastomal hernias with no increased morbidity.

Gallbladder leiomyoma in absence of immune system disorders: an unusual diagnosis.

Mesenchymal neoplasms of the gallbladder are rare and in particular leiomyomas of the gallbladder have been rarely reported, all of them in patients with immune system disorders.This is the first report in Spanish of a 23-year-old female patient with a gallbladder leiomyoma without associated immunodeficiency. The patient lacks a previous history of uterine leiomyoma or any other form of neoplasm. She refers several episodes of epygastralgia. A hydatic cyst led to an initial diagnosis and the gallbladder was removed by means of simple cholecystectomy. The abnormal macroscopic aspect of the sample prompted intraoperative biopsy which revealed a benign gallbladder angiomyoma. Subsequent immunohistochemical analysis of the resected sample yielded the diagnosis of intramural endocavitary leiomyoma negative for EBV and C-kit / CD-117. The patient has good general condition and remains asymptomatic 15 months after surgery.

[Diverticulectomy and cricopharyngeal myotomy for the treatment of Zenker's diverticulum. a presentation of 33 cases]. / Diverticulectomía y miotomía del cricofarígeo para el tratamiento del divertículo de Zenker. Presentación de una serie de 33 casos.

INTRODUCTION: The classic treatment of Zenker's diverticulum (ZD) has been cricopharyngeal myotomy (CPM), with the need or not to resect it being argued (diverticulectomy versus diverticulopexy). However, the advance of endoscopic techniques requires new treatment strategies to be established. We analyse the complications and clinical results of our series with cricopharyngeal myotomy and diverticulectomy in patients with ZD. METHOD: A retrospective, observational and descriptive study was conducted on 33 patients who, between January 1998 and December 2010, had a diverticulectomy and CPM performed in the university hospitals Virgen del Rocío in Seville and Carlos Haya in Malaga. Demographic and operative variables that might be associated with morbidity were analyzed. RESULTS: Seventeen patients were treated in the Carlos Haya Hospital, Málaga and sixteen in the Virgen del Rocío Hospital, Seville. Although there were no deaths, the morbidity rate of the series was 27% (9 cases), all associated with an oesophageal-cutaneous fistula. None of the variables studied were significantly associated with the appearance of morbidity. None of the patients had a clinical or radiological recurrence of ZD after a mean follow up of 44 months (range, 6 -192). CONCLUSIONS: Diverticulectomy combined with CPM is a good technique for the treatment of ZD, with excellent clinical and functional results in the medium to long term, despite the high morbidity in the form of an oesophageal-cutaneous fistula.

Influence of surgical site infection on oncological prognosis after curative resection for colorectal cancer: An observational single-institution study.

BACKGROUND: An exacerbated inflammatory response to post-operative infection could favor an environment in which residual viable tumor cells present in the surgical bed, bloodstream, or occult micrometastases can survive and progress to produce local or distant recurrence. In this regard, a surgical site infection (SSI) could be an important risk factor for disease progression. This study aimed to investigate the impact of SSI on long-term survival and recurrence of colorectal cancer. METHODS: Patients who underwent curative-intent resection for colorectal carcinoma between 2011 and 2013 were retrospectively analyzed. Overall and disease-free survival (DFS) and local recurrence rate for patients with and without SSI were analyzed. RESULTS: One hundred and thirty-eight patients were included in the study. Fifty-one (37%) patients showed SSI but revealed no differences in recurrence rate and overall survival compared with non-infected patients. However, the stratified analysis revealed that patients with an intra-abdominal abscess or an organ-space-infection showed a higher recurrence rate and a decreased 5-year overall and DFS. CONCLUSIONS: SSI may have an influence on the oncological prognosis and, therefore, could be considered a recurrence factor. Further multi-institutional studies are necessary to conclude a causal association.

ANTECEDENTES: Una respuesta inflamatoria exacerbada por una infección postoperatoria podría favorecer un entorno en el que células tumorales residuales viables presentes en el lecho quirúrgico, torrente sanguíneo o micrometástasis ocultas puedan sobrevivir y progresar para producir una recurrencia local o a distancia. En este sentido, una infección del sitio quirúrgico (ISQ) podría ser un factor de riesgo de progresión de la enfermedad. Este estudio tuvo como objetivo investigar el impacto de la ISQ en la supervivencia y recurrencia del cáncer colorrectal. MÉTODO: Todos los pacientes con carcinoma colorrectal sometidos a resección con intención curativa entre 2011 y 2013 fueron analizados retrospectivamente. Se analizó supervivencia global y libre de enfermedad y la tasa de recurrencia local en pacientes con cáncer colorrectal con y sin ISQ. RESULTADOS: Se incluyeron 138 pacientes. 51 (37%) sufrieron ISQ pero no mostraron diferencias en la tasa de recurrencia y supervivencia global respecto a los pacientes no infectados. Sin embargo, el análisis estratificado reveló que los pacientes con un absceso intraabdominal o una infección órgano-espacio mostraron una tasa de recurrencia más alta y una disminución en la supervivencia global y libre de enfermedad. CONCLUSIONES: La ISQ, en función de la gravedad y la respuesta inflamatoria que genera, puede influir en el pronóstico oncológico y, por lo tanto, podría considerarse un factor de recurrencia. Futuros estudios multicéntricos son necesarios para demostrar una posible asociación.

Laparoendoscopic Single-Site Cholecystectomy: First Experiences with a New Standardized Technique Replicating the Four-Port Technique.

BACKGROUND: After reports on laparoendoscopic single-site (LESS) cholecystectomy, concerns have been raised over the level of difficulty and a potential increase in complications when moving away from conventional gold standard multiport laparoscopy due to incomplete exposure and larger umbilical incisions. With continued development of technique and technology, it has now become possible to fully replicate this gold standard procedure through an LESS approach. First experiences with the newly developed technique and instrument are reported. METHODS: Fifteen patients presenting with cholelithiasis without signs of inflammation were operated using all surgical steps considered appropriate for the conventional four-port laparoscopic approach, but applied through a single access device. Operation-centered outcomes are presented. RESULTS: There were no peri- or postoperative complications. Mean operating time was 32.3 minutes. No conversion to regular laparoscopy was required. The critical view of safety was achieved in all cases. Mean skin incision length was 2.2 cm. CONCLUSION: The application of a standardized technique combined with the use of a four-port LESS device allows us to perform LESS cholecystectomy, giving us a correct exposure of the structures and without increasing the mean operating time combining previously reported advantages of LESS. A universal trait of any new technique should be safety and reproducibility. This will enhance its applicability by large number of surgeons and to large number of patients requiring cholecystectomy.

Unnoticed biloma due to liver puncture after Veress needle insertion.

Laparoscopic surgery has become more widespread in the last years. Creating the pneumoperitoneum is the first surgical procedure but it is still responsible for many of the adverse events described in this field. Until now, liver puncture producing a delayed biloma has not been described. We present a case where a biloma was developed after liver puncture by the Veress needle, during a laparoscopic procedure, and detected on the 3rd day. It was detected by CT scan and treated by laparoscopy. Biloma due to Veress needle is a new entity in the context of adverse events related to Veress needle insertion, which needs a high suspicious index. We recommend to do Palmer's test and to check the insertion and to look for possible lesions below with the camera in order to minimize incidence of such injuries. Should this happen, laparoscopic or percutaneous drainage are both suitable alternatives to solve this complication.

[Spleen-preserving surgery after blunt abdominal trauma with splenic hilum involvement]. / Cirugía preservadora de órgano tras traumatismo esplénico cerrado con implicación hiliar.

BACKGROUND: Splenic involvement secondary to blunt abdominal trauma is often treated by performing a splenectomy. The severity of the post-splenectomy syndrome is currently well known (blood loss, sepsis), so there is an increasing tendency to preserve the spleen. The case is presented of splenic preservation after blunt abdominal trauma with hilum involvement, emphasising the role of Floseal as a haemostatic agent, as well as the use of resorbable meshes to preserve the spleen. CLINICAL CASE: A 22-year-old woman presenting with a grade IV splenic lesion secondary to a blunt abdominal trauma after a traffic accident. Partial splenic resection was performed and bleeding was controlled with Floseal and use of a reinforcing polyglycolic acid mesh. No postoperative complications occurred, being discharged on day 5. The long-term follow-up has been uneventful. CONCLUSION: The use of haemostatic agents such as thrombin and the gelatine gel (FloSeal) and the use of polyglycolic acid meshes enable spleen-preserving surgery, making it a feasible and reproducible procedure and an alternative to classical splenectomy.
