Bundles reduce anastomosis leak in patients undergoing elective colorectal surgery. A propensity score-matched study.

Background: anastomosis leak still being a handicap in colorectal surgery. Bowel mechanical preparation and oral antibiotics are not a practice recommended in many clinical practice guides. The aim is to analyse the decrease in frequency and severity of postoperative complications, mainly related to anastomotic leak, after the establishment of a bundle. Methods: Single-center, before-after study. A bundle was implemented to reduce anastomotic leaks and their consequences. The Bundle group were matched to Pre-bundle group by propensity score matching. Mechanical bowel preparation, oral and intravenous antibiotics, inflammatory markers measure and early diagnosis algorithm were included at the bundle. Results: The bundle group shown fewer complications, especially in Clavien Dindós Grade IV complications (2.3% vs. 6.2% p < 0.01), as well as a lower rate of anastomotic leakage (15.5% vs. 2.2% p < 0.01). A significant decrease in reinterventions, less intensive unit care admissions, a shorter hospital stay and fewer readmissions were also observed. In multivariate analysis, the application of a bundle was an anastomotic leakage protective factor (OR 0.121, p > 0.05). Conclusions: The implementation of our bundle in colorectal surgery which include oral antibiotics, mechanical bowel preparation and inflammatory markers, significantly reduces morbidity adjusted to severity of complications, the anastomotic leakage rate, hospital stay and readmissions. Register study: The study has been registered at clinicaltrials.gov Code: nct04632446.

Monitoring intraoperative neuromuscular blockade and blood pressure with one device (TOF-Cuff): A comparative study with mechanomyography and invasive blood pressure. / Monitorización intraoperatoria del bloqueo neuromuscular y la presión arterial con un solo dispositivo (TOF-Cuff): estudio comparativo con la mecanomiografía y la presión arterial invasiva.

OBJECTIVE: The overall objective of the study is to determine the ability of TOF-Cuff device (blood-pressure modified cuff, including stimulation electrodes) to monitor with the same device the non-invasive blood pressure (NIBP) and the depth of a neuromuscular blockade (NMB) induced pharmacologically, by stimulation of the brachial plexus at the humeral level and recording evoked changes in arterial pressure. MATERIAL AND METHOD: Clinical, single-centre, open-controlled study with 32 adult patients ASA I-III for scheduled elective surgery under general anaesthesia in supine position, for the validation of neuromuscular monitoring, comparing the values obtained from neuromuscular relaxation TOF-Cuff with those obtained by mechanomyography (MMG) (control method) during the recovery phase of NMB, when a TOF ratio>0.7 and>0.9 (primary endpoint) were reached respectively. And an additional consecutive study of 17 patients for validation of NIBP monitoring with TOF-Cuff device vs invasive blood pressure measured by an intra-arterial catheter. All data were analyzed using the Bland-Altman method. RESULTS: Recovery from NMB measured with the TOF-Cuff was earlier compared to MMG. Comparing TOF-ratio>0.9 measured with TOF-Cuff vs TOF-ratio>0.7 with MMG, a specificity of 91% and a positive predictive value of 84% were obtained. In NIBP measurement, the mean error and standard deviation of both systolic blood pressure (1.6±7mmHg) and diastolic blood pressure (-3.4±6.3) were within the European accuracy requirements for medical devices. CONCLUSIONS: The TOF-Cuff device has been shown to be valid and safe in the monitoring of NMB and in the measurement of NIBP, with no patient presenting any adverse events, skin-level lesions or residual pain. It is not interchangeable with MMG, having a TOF-ratio>0.9 quantified by the TOF-Cuff device, a good correlation with a TOF-ratio>0.7 on MMG.

Carcinoma metaplásico condrosarcomatoide de mama, una entidad inusual / Chondrosarcomatous metaplastic carcinoma of the breast, a rare tumor

El carcinoma metaplásico de mama es una entidad infrecuente (menos del 0,2% de todos los cánceres de mama), que se caracteriza por presentar un componente mixto epitelial y mesenquimal. Este último componente es el que establece su clasificación histológica. Así, su diagnóstico es puramente histológico, pues clínica y radiológicamente no se diferencia de un carcinoma ductal típico. Presentamos un caso de carcinoma metaplásico de mama tipo condrosarcomatoide, cuyo diagnóstico definitivo requirió un estudio mediante técnicas de inmunohistoquímica para confirmar el componente epitelial maligno del tumor. Diagnosticarlo es importante porque su comportamiento es diferente, suelen diseminarse por vía hematógena (el carcinoma epitelial típico lo hace por vía linfática), las metástasis no se presentan en el momento del diagnóstico, sino durante el seguimiento, y su supervivencia a los 5 años es del 35% (AU)

Metaplastic carcinomas of the breast are uncommon, accounting for less than 0.2% of all breast cancers. Clinically and radiologically, metaplastic carcinomas are indistinguishable from typical ductal carcinomas, and the diagnosis is made histologically by the finding of a mesenchymal component. We present a case of chondrosarcomatous metaplastic breast carcinoma whose definitive diagnosis required immunohistochemical techniques to confirm the malignant epithelial component of the tumor. Accurate diagnosis is important because this tumor behaves differently: it usually spreads through the blood (whereas typical epithelial carcinomas spread through the lymph vessels), metastases present during follow-up rather than before diagnosis, and the five-year survival rate is 35% (AU)

Reduction in diabetic amputations over 15 years in a defined Spain population. Benefits of a critical pathway approach and multidisciplinary team work.

OBJECTIVE: To assess changes in diabetic lower-extremity amputations (LEA) rates in a defined population over a 15-year period, following a multidisciplinary approach including a critical pathway in an inpatient setting with standardized preoperative and postoperative care, as well as in an outpatient setting through the establishment of a diabetic foot clinic. METHODS: This is a study of the incidence and types of LEAs performed in patients with diabetic foot disease complicated admitted to Morales Meseguer Hospital (Murcia, Spain), a large district general hospital, before (1998-2000) and after (2001-2012) of the introduction of better organized diabetes foot care. Hospital and clinic characteristics to the success of the programme are described. All cases of LEA in diabetic patients (1998-2012) within the area were identified by ICD-9-Clinical modification (CM) diagnostic codes. A chi square test was used to compare the frequency and level of amputations. RESULTS: Over all inpatients with diabetes admitted with foot infections and gangrene, there was a significant decrease in the proportion of total major amputations (47%) and elective major amputations (66%) (p<0.001). The incidence of total major amputations rates per 100.000 of the general population fell with statistical significance (p=0.009). The biggest improvement in LEA incidence was seen in the reduction of major elective amputation with fell 60%, from 7.6 to 3.1 per 100,000 (p<0.001). CONCLUSIONS: Significant reductions in total and major amputations rates occurred over the 15-year period following improvements in foot care services included multidisciplinary teamwork (critical pathway and diabetic foot clinic).

Type II intrapancreatic choledochal malignant cyst in adults: duodenopancreatectomy.

A 62-year-old female patient was admitted for abdominal pain and vomiting. Imaging tests revealed a solid-cystic lesion at the head of the pancreas communicating with the distal bile duct. A Todani type II choledochal cyst was diagnosed with neoplastic degeneration after cytological diagnosis with endoscopic ultrasound-guided puncture. The patient was treated with a cephalic duodenopancreatectomy with curative intention.

Bariatric surgery, a risk factor for rhabdomyolysis

La rabdomiolisis tras cirugía bariatrica es una complicación rara pero posible. Presentamos un caso de rabdomiolisis y fallo renal agudo tras by-pass gástrico laparoscópico en paciente con obesidad mórbida. Su conocimiento puede ayudar a predecir y manejar esta complicación infradiagnosticada cuyo diagnostico precoz mejora el tratamiento de estos pacientes y previene las complicaciones posteriores (AU)

Rhabdomyolysis has been increasingly recognized as a complication of bariatric surgery. We report a case of this complication and its consequences, in a patient who had undergone bariatric surgery, with a very high creatine kinase (CK) concentration, and whose renal function failed. Obesity causes a range of effects on all major organ systems. Knowledge of these effects and issues specific to the intensive care unit care of bariatric patients can help to predict and manage this underestimated complication in this population in which early diagnosis can alter the outcome (AU)

Is the outcome of laparoscopic incisional hernia repair affected by defect size? A prospective study.

BACKGROUND: This study was performed to determine if defect size after laparoscopic incisional hernia repair is predictive of recurrence during the long-term follow-up evaluation. METHODS: We performed a prospective clinical study on 310 patients who underwent laparoscopic incisional hernia repair to identify predictable risk factors for hernia recurrence. Univariate and multivariate Cox regression analysis were used. The defect size was analyzed with curve receiver operating characteristic curve. RESULTS: The overall recurrence rate was 6% after an average follow-up period of 60 months. On univariate analysis of the defect size (categories: <10 cm, 10-12 cm, and >15 cm), obesity, previous repairs, hernia location, surgical time, hospital stay, morbidity, and recurrences were significantly different (P < .001). By multivariate analysis, only obesity and defect size were independent prognostic factors (P < .001). CONCLUSIONS: The predictive value of defect size is shown. Patients with large defects have a higher risk of recurrence. Our study recommends reserving the laparoscopic technique for hernias not exceeding 10 cm in size, where it can be put to better use.
