Perioperative and oncologic outcomes of interval colectomy performed by acute care surgeons after stenting as a bridge to surgery for left-sided malignant colonic obstruction are non-inferior to the outcomes of colorectal surgeons in the elective setting: single center experience.

PURPOSE: To analyze if perioperative and oncologic outcomes with stenting as a bridge to surgery (SEMS-BS) and interval colectomy performed by acute care surgeons for left-sided occlusive colonic neoplasms (LSCON) are non-inferior to those obtained by colorectal surgeons for non-occlusive tumors of the same location in the full-elective context. METHODS: From January 2011 to January 2021, patients with LSCON at University Regional Hospital in Málaga (Spain) were directed to a SEMS-BS strategy with an interval colectomy performed by acute care surgeons and included in the study group (SEMS-BS). The control group was formed with patients from the Colorectal Division elective surgical activity dataset, matching by ASA, stage, location and year of surgery on a ratio 1:2. Stages IV or palliative stenting were excluded. Software SPSS 23.0 was used to analyze perioperative and oncologic (defined by overall -OS- and disease free -DFS-survival) outcomes. RESULTS: SEMS-BS and control group included 56 and 98 patients, respectively. In SEMS-BS group, rates of technical/clinical failure and perforation were 5.35% (3/56), 3.57% (2/56) and 3.57% (2/56). Surgery was performed with a median interval time of 11 days (9-16). No differences between groups were observed in perioperative outcomes (laparoscopic approach, primary anastomosis rate, morbidity or mortality). As well, no statistically significant differences were observed in OS and DFS between groups, both compared globally (OS:p < 0.94; DFS:p < 0.67, respectively) or by stages I-II (OS:p < 0.78; DFS:p < 0.17) and III (OS:p < 0.86; DFS:p < 0.70). CONCLUSION: Perioperative and oncologic outcomes of a strategy with SEMS-BS for LSCON are non-inferior to those obtained in the elective setting for non-occlusive neoplasms in the same location. Technical and oncologic safety of interval colectomy performed on a semi-scheduled situation by acute care surgeons is absolutely warranted.

[Characteristics of motor behaviour in premature infants during the first months of postnatal life. A literature review]. / Rasgos característicos del comportamiento motor del niño con prematurez durante los primeros meses de vida posnatal: una revisión de la literatura.

OBJECTIVE: To describe the characteristics of motor behaviour in premature infants during the first months of postnatal life, according to the available evidence. MATERIALS AND METHODS: A systematic literature review was carried out; this method forms part of secondary studies under investigation and describes a phenomenon in detail based on primary sources of information. RESULTS: The literature search in the databases consulted yielded 7,228 articles; of these, 15 more were identified through "snowball" search strategies. At the start of the screening process, 63 eligible records were chosen based on their title and summary, and 14 were excluded because they were duplicates. A total of 49 articles were selected for a full text revision and, of these, 37 were excluded because they did not meet all the inclusion criteria. Finally, 12 articles were selected to prepare the qualitative synthesis of the present research work. CONCLUSIONS: In comparison with neonates born at term, premature infants demonstrate a particular motor repertoire, due to the immaturity of their systems; their motor behaviour follows a line of development mainly characterised by deficits in muscle tone, postural control, muscle balance, and antigravity muscle activation.

Liver transplant results for hepatocellular carcinoma applying strict preoperative selection criteria.

INTRODUCTION: Liver transplantation is currently the best therapeutic option for small hepatocellular carcinoma (HC) in selected cirrhotic patients. The main aim of this study was to analyze the results of a recent series of liver transplant cirrhotic patients with small HC applying strict preoperative selection criteria. PATIENTS AND METHODS: During a period of 6 years we performed 53 liver transplants with a final diagnosis of HC on cirrhosis. The selection criteria for liver transplantation (LT) by modern imaging techniques were the Milan criteria (TNM I and II of the modified classification). RESULTS: Of the 53 patients, 44 (83%) were transplanted with preoperatively known HC, and 9 (17%) with incidental HC. The mean time on the waiting list was 74 +/- 62 days. Despite using strict selection criteria, 23 patients (43%) exceeded the Milan criteria in the specimen and 17 (32%) even exceeded the extended criteria of the UCSF. With a mean follow-up of 2 years, only two patients have developed recurrences. The overall survival at 1, 3, and 5 years was 80%, 70%, and 70%, respectively. The survival of patients that exceeded the Milan or USF criteria at 1, 3, and 5 years was 72% and 76%; 67% and 69%; 67% and 69%, respectively. CONCLUSIONS: The results of liver transplantation for HC are excellent when applying strict preoperative selection criteria. The current imaging methods lead to a considerable infrastaging percentage (30% to 40%), extending the indications for liver transplant due to HC beyond the scope that clinical reports would justify.

Preoperative factors and models predicting mortality in liver transplantation.

We analyzed preoperative factors related to postoperative mortality after liver transplantation among a cohort of 268 consecutive liver transplant patients over 6 years. We studied the impact of 10 recipient variables, 14 donor features, and three operative aspects. We also studied the correlation with death and survival using various predictive scores (Child, Cordoba Score, MELD, and UCLA). Univariate analysis showed that the factors with a significant association with postoperative mortality were the use of noradrenaline in the donor, total ischemia time (>12 hours), and transplant indication (hepatitis C virus versus the rest). Multivariate analysis of mortality showed the impact of female donor sex, recipients over >60 years, recipient albumin less than 2.8, and total graft ischemia time more than 12 hours. Univariate analysis of 1-year survival showed a statistically significant relation with D/R gender similarity, as well as donor GOT (>170) and GPT (>140) values. Multivariate analysis of 1-year survival showed donor GOT (>170) and donor/recipient gender similarity to be significant. Concerning the prediction models, Child-Pugh (AB versus C) best determined postoperative mortality (P < .006), MELD was predictive of 1-year survival (P < .03). The most important variables related to postoperative mortality were total ischemia time over 12 hours, recipient albumin less than 2.8, and age above 60 years. The variable with most impact on 1-year survival was the degree of graft hepatocyte lesion as determined by GOT. The Child-Pugh system is still the best indicator of postoperative mortality, although MELD may also be a good predictor of survival.

[Laparoscopic bariatric surgery: proximal gastric bypass]. / Cirugía bariátrica laparoscópica: bypass gástrico proximal.

The spectacular increase in the prevalence of obesity in our society and the significant complications and comorbidities that it gives rise to have stimulated the interest of scientists and public in this pathology. Surgical treatment is at present the only efficient and lasting treatment for morbid obesity and in many cases it appreciably improves, and even definitively cures, associated complications such as the case of diabetes or hypertension. Amongst the different techniques of bariatric surgery, the gastric bypass (GBP) seems to be definitively establishing itself, since it offers an excellent balance between loss of weight (>70% of the excess), surgical risk and subsequent quality of life. The possibility of carrying out this technique employing a laparoscopic approach has improved its acceptance by doctors and patients while it has made it possible to reduce morbidity and mortality, length of hospital stay and costs. Proximal GBP is carried on those patients with an BMI <60 Kg/m2; for BMI >60 Kg/m2 the GBP employed is denominated distal. Between October 2003 and November 2005, our centre performed 55 laparoscopic proximal Roux-en-Y gastric bypasses via laparoscopy. These involved 42 women and 13 males with an average age of 44 years. The average BMI was 43.5 (35-55.8). The average basal weight was 116.15 Kg. There was no peroperative mortality, nor reinterventions. The BMI after 12 months was 28.4. The average basal weight was 74.2 Kg. Laparoscopic Roux-en-Y proximal gastric bypass is a safe and efficient technique for the treatment of morbid obesity.

[Hepatic and pancreatic laparoscopic surgery]. / Cirugía laparoscópica hepática y pancreática.

The development of laparoscopic surgery also includes the more complex procedures of abdominal surgery such as those that affect the liver and the pancreas. From diagnostic laparoscopy, accompanied by laparoscopic echography, to major hepatic or pancreatic resections, the laparoscopic approach has spread and today encompasses practically all of the surgical procedures in hepatopancreatic pathology. Without forgetting that the aim of minimally invasive surgery is not a better aesthetic result but the reduction of postoperative complications, it is undeniable that the laparoscopic approach has brought great benefits for the patient in every type of surgery except, for the time being, in the case of big resections such as left or right hepatectomy or resections of segments VII and VIII. Pancreatic surgery has undergone a great development with laparoscopy, especially in the field of distal pancreatectomy due to cystic and neuroendocrine tumours where the approach of choice is laparoscopic. Laparoscopy similarly plays an important role, together with echolaparoscopy, in staging pancreatic tumours, prior to open surgery or for indicating suitable treatment. In coming years, it is to be hoped that it will continue to undergo an exponential development and, together with the advances in robotics, it will be possible to witness a greater impact of the laparoscopic approach on the field of hepatic and pancreatic surgery.

[Laparoscopic biliary surgery]. / Cirugía laparoscópica biliar.

The following article briefly sets out the possible new protocols that can be applied in biliary pathology, arising from the changes brought about by the appearance of new techniques of laparoscopic biliary surgery. It offers a synthesis of the latest and most novel articles on surgical technique and management in different biliary pathologies such as choledocholithiasis and cholecystitis. It can be concluded that management will differ greatly, depending on the technical capacities of the centre that is called upon to deal with one of these pathologies. A standard protocol for everybody cannot thus be established at present. The differences between endoscopic retrograde cholangiopancreatography and intraoperative laparoscopic cholangiography have still to be demonstrated, it is not possible to make generalisations about whether one technique is more useful than the other. The same could be said about whether access to the main biliary path should be achieved through the cystic conduct or whether, on the contrary, a choledochotomy should be performed.

Cases of swine flu in kidney transplant recipients in our hospital.

In late March 2009, an outbreak of influenza A virus infection was detected in Mexico with subsequent cases observed in many other countries. The pandemic was caused by an H1N1 virus that represents a quadruple reassortment of 2 swine strains, 1 human strain, and 1 avian strain of influenza. Until February 1, 2010, a total of 47 cases of influenza A (Inf A) were recorded by the Spanish Society of Nephrology in kidney transplant recipients. Herein we have reported our 3 cases (6.4%) in this registry. A 17-year-old girl with hepatorenal polycystosis received a liver and kidney transplant at 37 months previously. She displayed high fever and mild respiratory symptoms that resolved without treatment. A 38-year-old woman with chronic renal failure (CRF) of undetermined etiology received a kidney transplant 9 months previously. She was admitted with a 5-day history of febrile syndrome and respiratory symptoms, with extensive bilateral pneumonia and acute severe respiratory failure that required admission to the intensive care unit. Her evolution was satisfactory. A 38-year-old woman with CRF of undetermined etiology received a kidney transplant 2.5 months previously. She was admitted in November 2009 with a 2-week history of fever, myalgia, general malaise, cough, and expectoration. Her course was satisfactory. In these cases we determined H1N1 Inf A pandemic variant by detection of Inf A Matrix Protein 2 gene M2 and the specific H1 gene for influenza pandemic H1N1 2009 with reverse transcriptase polymerase chain reaction Inf A/H1N1 (Roche). The 3 cases of Inf A in kidney transplant recipients recorded in the province of Almeria occurred in young women shortly after kidney transplantation, and with no other risk factors apart from those associated with the transplantation itself. From the consideration of respiratory and renal situations, their courses were satisfactory.

Cirugía laparoscópica biliar / Laparoscopic biliary surgery

El siguiente artículo trata de exponer brevemente los posibles nuevos protocolos que se pueden aplicar en la patología biliar, a raíz de los cambios acaecidos con la aparición de las nuevas técnicas de cirugía biliar laparoscópica. Pretende realizar una síntesis de los últimos y más novedosos artículos sobre técnica quirúrgica y manejo en distintas patología biliares tales como coledocolitiasis o colecistitis.Se puede concluir que el manejo diferirá mucho según las capacidades técnicas de un centro sobre el que recaiga una de estas patologías. Por tanto, actualmente no se puede imponer un protocolo estándar para todo el mundo.Las diferencias entre colangiopancreatografía retrógrada endoscópica y colangiografía intraoperatoria laparoscópica, todavía están por demostrar, no pudiéndose generalizar sobre si una técnica tiene más indicación que la otra. Lo mismo se podría decir sobre si el acceso a la vía biliar principal debe hacerse desde el conducto cístico o por el contrario debe realizarse una coledocotomía

Cirugía bariátrica laparoscópica: bypass gástrico proximal / Laparoscopic bariatric surgery: proximal gastric bypass

El espectacular aumento en la prevalencia de la obesidad en nuestra sociedad y las importantes complicaciones y comorbilidades que origina ha despertado el interés de científicos y público en esta patología. El tratamiento quirúrgico es en la actualidad el único tratamiento eficaz y duradero para la obesidad mórbida y en muchos casos, mejora sensiblemente e incluso cura definitivamente complicaciones asociadas como es el caso de la diabetes o la hipertensión. De entre las diversas técnicas de cirugía bariátrica, parece imponerse definitvamente el by-pass gástrico (BPG), al ofrecer un excelente balance entre pérdida de peso (>70% del exceso) y riesgo quirúrgico y calidad de vida posterior. La posiblidad de realizar esta técnica mediante un abordaje laparoscópico ha mejorado su aceptación por parte de médicos y pacientes al tiempo que ha permitido disminuir morbimortalidad, estancia y costes. El BPG proximal se realiza en aquellos pacientes con un IMC <60 Kg/m2; para mayores se realiza uno denominado como distal. Entre octubre de 2003 y noviembre de 2005 se han realizado en nuestro centro 55 BPG proximales en Y de Roux vía laparoscópica. Se trata de 42 mujeres y 13 varones de edad media de 44 años. El IMC medio es de 43,5 (35-55,8). La media de peso basal es de 116,15 Kg. No hubo mortalidad peroperatoria ni reintervenciones. El IMC medio a los 12 meses es de 28,4. La media de peso basal es de 74,2 Kg. El BPG proximal en Y de Roux vía laparoscópica es una técnica segura y eficaz para el tratamiento de la obesidad mórbida
