Thoracic aortic cannulation with antegrade perfusion for the procurement of abdominal organs.

The definitive acceptance of an organ as valid for transplant depends on the surgical team performing the multiorgan recovery; and unexpected difficulties can occur. The demographic characteristics of donors has changed, and some accepted donors can present difficulties in surgical technique and risky decisions on the validity of the retrieved organ or organs. An alternative method to the cannulation of the abdominal aorta is proposed when there is evidence of disease in the infrarenal aorta during the multiorgan procurement. The retrocardiac descending thoracic aorta is cannulated using an antegrade perfusion; this technique allows an increase in organ recovery.

Pharmacological intestinal obstruction because of calcium polystyrene sulfonate administration.

Cation exchange resins are commonly used as treatment for hyperkalaemia in patients with chronic renal disease. There is a relation between cation exchange resins and the development of gastrointestinal adverse effects. A case of an intestinal obstruction at the terminal ileum is presented that underwent an ileocolic resection because of a critical stenosis of the intestine. The pathologist revealed abundant inflammatory cells together with deposits of calcium polystyrene crystals responsible of the intestinal obstruction. A rare cause of intestinal obstruction to bear in mind in chronically medicated patients with cation exchange resins.

[Adenocarcinoma arising in Meckel's diverticulum: a case report and literature review]. / Adenocarcinoma sobre divertículo de Meckel: presentación de un caso y revisión de la literatura.

Meckel's diverticulum is the most common congenital anomaly of the gastrointestinal tract. The presence of malignant lesions arising in the diverticulum is very rare, the most common malignant lesion being sarcoma, followed by carcinoid tumors, and less frequently by adenocarcinomas. We present the case of an 86-year-old man who developed acute abdomen. Surgery revealed a perforated Meckel's diverticulum. Histology identified a poorly-differentiated adenocarcinoma arising in Meckel's diverticulum. We provide a review of the literature.

[Role of laparoscopic surgery in the treatment of achalasia: an analysis of 50 cases]. / Papel del tratamiento quirúrgico por vía laparoscópica de la achalasia de cardias: análisis de 50 casos.

UNLABELLED: Achalasia is an uncommon oesophageal motor disorder, with a controversial therapeutic management. AIM: The aim of our study was to analyse our experience in the management of achalasia, assessing the impact of minimally invasive surgery, its complications and its outcomes in the short and medium term. METHODS: A retrospective and descriptive study was designed, including all patients operated on between 1999 and 2010 with the diagnosis of achalasia. Previous diagnostic tests, duration of symptoms, previous non-surgical treatment, surgical approach, associated antireflux intervention, surgical time and perioperative complications were analysed. RESULTS: A total of 50 patients, 24 males and 26 females, with a mean age of 47 years underwent laparoscopic surgery. The mean duration of the disease was 2 years. Eleven (22%) patients had received endoscopic treatment (1-4 sessions) prior to the surgery, with 100% of symptomatic recurrence. The surgery was accompanied by a Dor fundoplication in 48 patients, and Toupet fundoplication in the remaining two. The mean surgical time was 123 minutes. There were 9 intraoperative complications (5 gastric mucosal perforations, 2 bleeding, 1 liver injury and 1 aspiration); 4 postoperative complications (3 scapular pain and 1 sub-phrenic collection) were reported. The long-term subjective symptomatic response was excellent/good in 84% of patients, intermediate in 12% and a poor response in 4%. The mean follow-up was 28 months. CONCLUSIONS: Heller cardiomyotomy should be the treatment of choice in selected Achalasia patients, because of its short and long term outcomes, and its low morbidity.

Evaluation of the effect of triclosan coated sutures in the prevention of surgical site infections in a Spanish hospital setting: A prospective, observational study.

BACKGROUND: Surgical site infections (SSIs) are one of the most frequently reported types of hospital-acquired infection and are associated with substantial clinical and economic burden. AIM: To assess the incidence of SSIs and analyze contributing risk factors in a real-world Spanish hospital setting before and after the implementation of triclosan-coated sutures (TCS). METHODS: A prospective, observational study was conducted at Hospital Clínico Universitario de Santiago de Compostela, Spain. Enrolled patients underwent surgery in the following specialties: general surgery, urology, neurosurgery, gynaecology, and traumatology. The primary outcome of the study was SSI incidence, assessed at a 30-day follow-up. Secondary outcomes were length of hospital stay, and readmission, reintervention, and mortality rates, also at 30 days. FINDINGS: 5,081 patients were included in the study, of which 2,591 were treated using non-coated sutures (NCS) and 2,490 using TCS. After adjusting for potential confounders, TCS significantly reduced SSI rate by 36%, compared with NCS (odds ratio [OR]: 0.64; 95% confidence interval [CI]: 0.48-0.85; P<0.003). When stratified by wound classification, a statistically significant reduction in SSI incidence, in favour of TCS use, was observed for Class IV (dirty) wounds (35.6% versus 22.7% for NCS and TCS, respectively; OR: 0.53; 95% CI: 0.31-0.90). CONCLUSION: The use of TCS reduced SSI risk when compared with NCS. This reduction was significant for Class IV wounds, providing evidence that supports the use of TCS for this type of wound.

Resección de GIST rectal mediante cirugía transanal mínimamente invasiva (TAMIS) tras neoadyuvancia con imatinib / Resection of a rectal gastrointestinal stromal tumour by transanal minimally invasive surgery (TAMIS) after neoadjuvant treatment with Imatinib

Resumen El tratamiento primario de elección para los pacientes con una tumoración GIST localizada es la extirpación quirúrgica completa con márgenes microscópicos negativos. Sin embargo, en un espacio tan reducido como el de la pelvis, la resección completa de una tumo-ración rectal grande es difícil y necesita en ocasiones una amputación abdomino-perienal. En nuestro caso, con la finalidad de reducir el tamaño del tumor y la morbilidad asociada a procedimientos quirúrgicos más agresivos se introdujo el tratamiento con imatinib, con intención neoadyuvante monitorizando la respuesta mediante ecoendoscopia. La respuesta obtenida, rediciendo el volumen tumoral, modificó la estrategia quirúrgica inicial y fue posible conseguir una resección satisfactoria mediante cirugía transanal mínimamente invasiva (TAMIS), preservando los esfínteres anales y soslayando la morbilidad genitourinaria asociada a la excisión mesorectal.

Abstract The primary treatment of choice for patients with a localised gastro-intestinal stromal tumour (GIST) is complete surgical excision with negative microscopic margins. However, in a space as small as that of the pelvis, complete resection of a large rectal tumour is difficult, and sometimes requires an abdominoperineal amputation. In order to reduce the size of the tumour, as well as the morbidity associated with more aggressive surgical procedures, neoadjuvant treatment with Imatinib was introduced in this case, with the response being monitored by of endoscopic ultrasound. The response obtained by reducing the tumour volume modified the strategy, making it possible to obtain a satisfactory resection using transanal minimally invasive surgery (TAMIS), preserving the anal sphincters and avoiding the genitourinary morbidity associated with the mesorectal excision.

Cáncer de recto localmente avanzado. La necesidad de la superespecialización / Locally advanced rectal cancer. The need for further specialization

Presentamos un caso que por sus connotaciones diagnósticas y terapéuticas resulta especialmente didáctico e ilustrativo, pues aborda el cómo, el quién y dónde debe realizarse la cirugía de cáncer de recto localmente avanzado. Ilustra el manejo diagnóstico y la estadificación del cáncer de recto en el momento actual. Este caso se aborda en el comité de forma multidisciplinar, y reúne los distintos avances en la cirugía de cáncer de recto de los últimos años (escisión total mesorrectal, abordaje laparoscópico, radioterapia intraoperatoria, resección perineal extendida, reparación del suelo pélvico con material protésico). Todo ello aunado a la opinión de que deben ser instituciones y grupos muy especializados y dedicados al tratamiento de esta patología los que deberían centralizar su atención médica.

We present a case, which due to its diagnostic and therapeutic connotations makes it especially educational, as it addresses the how, the who and where should the surgery be performed for locally advanced rectal cancer. It illustrates the diagnostic management and staging of rectal cancer at the present time. The case is approached in a multidisciplinary committee manner, and binds the various advances in surgery of rectal cancer in recent years (total meso-rectal excision, laparoscopy, intraoperative radiotherapy, extended perineal resection, pelvic floor repair with prosthetic material). This serves to underline the view that there must be highly specialized institutions and groups dedicated to the treatment of this condition in order to centralize its health care.

[Management of patients with iatrogenic bile duct injury]. / Tratamiento de pacientes con lesiones graves de la vía biliar.

OBJECTIVES: The aim of this study is to present an analysis of 30 patients with major bile duct injuries in a single hospital centre. MATERIAL AND METHOD: From January 2001 to December 2006, a prospective database was kept of all patients with a bile duct injury (BDI) following laparoscopic cholecystectomy (LC). Patients' charts were reviewed to analyse perioperative surgical management. RESULTS: Over 6 years, 30 patients were treated for a major BDI. Patient demographics were not notable for 16 women (53%) and 14 men (47%) with a mean age of 58.9 years. Twenty of them sustained their BDI at another hospital. The mean interval from the time of BDI to referral was 17.4 days. A total of 30 patients underwent definitive biliary reconstruction, including 17 hepaticojejunostomies (56.7%), 8 end-to-end repairs (20%), 2 choledochoduodenostomies (6.7%), 3 liver transplantations (10%), 1 hepatectomy and 1 Whipple (3.3%). There were 2 deaths in the postoperative period (6.7%). Thirteen (43.3%) sustained at least 1 postoperative complication. The most common complications were cholangitis (20%), and intra-abdominal abscess/biloma (23.3%). The mean postoperative length of stay was 17.46 days. CONCLUSIONS: Bile duct injury is a serious complication that affects mostly individuals with benign disease. Various subsequent procedures (surgical and/or endoscopic) are almost always necessary for its correction, with a high socioeconomic cost that imposes great suffering on the patients and their relatives. Clearly, all efforts should be made to prevent such accidents.
