ABSTRACT

Introducción: El sangrado digestivo intraluminal postoperatorio es una entidad poco frecuente y su manifestación clínica no difiere de la hemorragia digestiva baja de otra etiología. A pesar de que su presentación más habitual es la hematoquecia autolimitada en la primera deposición, en un discreto porcentaje puede requerir transfusiones, tratamiento endoscópico, hemodinámico, o incluso cirugía. Objetivo: Analizar los pacientes con sangrado digestivo intraluminal postoperatorio tratados en un centro de alta complejidad y realizar una revisión bibliográfica del tema. Diseño: Estudio retrospectivo, descriptivo. Material y métodos: Pacientes con sangrado anastomótico durante el post operatorio inmediato de una colectomía izquierda, operados en el Servicio de Cirugía General y Coloproctología desde enero del 2017 a diciembre del 2021. Las variables estudiadas fueron edad, sexo, anticoagulación y su causa, descenso de hemoglobina, cirugía realizada y su indicación, vía de abordaje, configuración de la anastomosis, electividad de la cirugía, complicaciones, días de internación y manejo terapéutico. Resultados: Se incluyeron 4 pacientes con una edad media de 72 (rango 54-87) años y una distribución por sexo de 1:1. En todos la colectomía izquierda fue programada y en 3 el abordaje fue laparoscópico. La anastomosis fue termino-terminal con sutura mecánica circular. Todos los pacientes presentaron sangrado en las primeras 24 horas postoperatorias. El tratamiento fue decidido de acuerdo a la condición hemodinámica: en los 2 pacientes con estabilidad hemodinámica fue suficiente el tratamiento conservador con reanimación y transfusiones. Los otros 2 que presentaron inestabilidad hemodinámica requirieron manejo intervencionista con endoscopía rígida, videocolonoscopía y cirugía. Conclusión: El sangrado intraluminal es una complicación poco frecuente de la anastomosis colorrectal que requiere manejo intervencionista solo en los pacientes que presentan inestabilidad hemodinámica.

Introduction: Postoperative intraluminal gastrointestinal bleeding is a rare entity and its clinical manifestation does not differ from lower gastro-intestinal bleeding of another etiology. Despite the fact that its most common presentation is self-limited hematochezia at the first stool, in a small percentage it may require transfusions, endoscopic or hemodynamic management, or even surgery. Aim: To analyze the patients with postoperative intraluminal gastrointestinal bleeding treated in a tertiary center and to carry out a bibliographic review of the subject. Design: Retrospective descriptive study. Material and methods: Patients with immediate postoperative anastomotic bleeding from a left colectomy, operated on at the General Surgery and Coloproctology Service from January 2017 to December 2021 were included. The variables recorded were age, sex, anticoagulation and its cause, decrease in hemoglobin, procedure performed and its indication, surgical approach, type of anastomosis, electiveness of surgery, complications, hospital stay and management. Results: Four patients with a mean age of 72 (range 54-87) years and a 1:1 gender distribution were included. All procedures were elective and 3 laparoscopic. All anastomoses were performed end-to-end with a circular stapler. All patients presented bleeding in the first 24 postoperative hours. The treatment was decided according to the hemodynamic condition; patients with hemodynamic stability (2) received medical treatment while those with hemodynamic instability (2) required interventional management with rigid endoscopy, colonoscopy and surgery. Conclusion: Intraluminal bleeding is a rare complication of colorectal anastomosis that requires interventional management only in patients with hemodynamic instability. (AU)

ABSTRACT

Intersphincteric resection (ISR) surgery increases the rate of anal sphincter preservation in patients with ultra-low rectal cancers. However, the anastomotic site of ISR surgery is at risk for structural healing complications such as anastomotic leakage, anastomotic dehiscence, secondary anastomotic stenosis, chronic presacral sinus, rectovaginal fistula, and rectourethral fistula, which can lead to a persistent defunctioning ostomy or a secondary permanent colostomy. This article systematically describes the preoperative high-risk factors and characteristics of anastomotic site structural healing complications after ISR surgery, as well as the management of the anastomotic site during various stages including hospitalization, from discharge to one month after surgery, from one month after surgery to before stoma reversal, and after stoma reversal. This is to provide a clearer understanding of the risks associated with the anastomotic site at different stages of the healing process and to timely detect and actively manage related complications, thereby reducing the rate of permanent colostomy and truly achieving the dual goals of "survival benefit" and "quality of life improvement" in ISR surgery.

ABSTRACT

Objective: To assess the effectiveness of transanal drainage tube (TDT) in reducing the incidence of anastomotic leak following anterior resection in patients with rectal cancer. Methods: We conducted a systematic search for relevant studies published from inception to October 2022 across multiple databases, including PubMed, Embase, Web of Science, Cochrane Library, CNKI, Wanfang, and VIP. Meta-analysis was performed using Review Manager 5.4 software. The primary outcomes included total incidence of anastomotic leak, grade B and C anastomotic leak rates, reoperation rate, anastomotic bleeding rate, and overall complication rate. Results: Three randomized controlled trials involving 1115 patients (559 patients in the TDT group and 556 in the non-TDT group) were included. Meta-analysis showed that the total incidences of anastomotic leak and of grade B anastomotic leak were 5.5% (31/559) and 4.5% (25/559), respectively, in the TDT group and 7.9% (44/556) and 3.8% (21/556), respectively, in the non-TDT group. These differences are not statistically significant (P=0.120, P=0.560, respectively). Compared with the non-TDT group, the TDT group had a lower incidence of grade C anastomotic leak (1.6% [7/559] vs. 4.5% [25/556]) and reoperation rate (0.9% [5/559] vs. 4.3% [24/556]), but a higher incidence of anastomotic bleeding (8.2% [23/279] vs. 3.6% [10/276]). These differences were statistically significant (P=0.003, P=0.001, P=0.030, respectively). The overall complication rate was 26.5%(74/279) in the TDT group and 27.2% (75/276) in the non-TDT group. These differences are not statistically significant (P=0.860). Conclusions: TDT did not significantly reduce the total incidence of anastomotic leak but may have potential clinical benefits in preventing grade C anastomotic leak. Notably, placement of TDT may increase the anastomotic bleeding rate.

ABSTRACT

Objective: To retrospectively analyze the risk factors of anastomotic leakage in the neck after esophageal cancer and establish a nomogram prediction model that can accurately predict the occurrence of anastomotic leakage in the neck of the patient. Methods: The study retrospectively analyzed 702 patients who underwent radical esophageal cancer surgery between January 2010 and May 2015 at Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. A multivariate logistic regression model was used to determine the risk factors for neck anastomotic leak, and a nomogram model was constructed, internal validation methods were used to evaluate and verify the predictive effectiveness of the nomogram. Results: There were 702 patients in the whole group, 492 in the training group and 210 in the validation group. The incidence of postoperative cervical anastomotic leak was 16.1% (79/492) in 492 patients with esophageal cancer in the training group. Multifactorial analysis revealed calcification of the descending aorta (OR=2.12, 95% CI: 1.14, 3.94, P=0.018), calcification of the celiac artery (OR=2.29, 95% CI: 1.13, 4.64, P=0.022), peripheral vascular disease (OR=5.50, 95% CI: 1.64, 18.40, P=0.006), postoperative ventilator-assisted breathing (OR=5.33, 95% CI: 1.83, 15.56, P=0.002), pleural effusion or septic chest (OR=3.08, 95% CI: 1.11, 8.55, P=0.031), incisional fat liquefaction and infection (OR=3.49, 95% CI: 1.68, 7.27, P=0.001) were independent risk factors for the development of cervical anastomotic leak after esophageal cancer surgery. The results of the nomogram prediction model showed that the consistency indices of the training and external validation groups were 0.73 and 0.74, respectively (P<0.001), suggesting that the prediction model has good predictive efficacy. Conclusion: The nomogram prediction model can intuitively predict the incidence of postoperative cervical anastomotic leakage in patients with high prediction accuracy, which can help provide a clinical basis for preventing cervical anastomotic leak and individualized treatment of patients.

ABSTRACT

Pancreaticojejunostomy is the most common anastomosis following pancreaticoduodenectomy and middle pancreatectomy. The detailed surgical technics of pancreaticojejunostomy vary dramatically, but none of them can achieve zero fistula rate. In recent years,with the development of new surgical concept,application of new surgical technology, high-tech materials and instruments,the incidence of pancreatic fistula has decreased. At the same time,researches on investigating the risk factors of pancreaticojejunostomy are gradually deepening. Based on years of surgical experience on pancreaticojejunostomy and current literatures, this paper analyzes the factors affecting the effect of pancreaticojejunostomy, such as the patient's basic physical state,pancreatic texture and diameter of the pancreatic duct,pathology and course of the disease,surgical technology and perioperative management,and summarizes six technical principles for pancreaticojejunostomy to be shared with surgical comrades:appropriate tension,protection of blood supply,hermetic closure of pancreatic section,accurate connection of pancreatic duct and intestinal mucosa,individualization,learning and accumulation of experience.

ABSTRACT

Objective: To examine the clinical value of routine contrast esophagram (RCE) for the diagnosis of anastomotic leakage (AL) after three-incision esophagectomy with cervical anastomosis. Methods: Clinical data of 1 022 patients with esophageal cancer who underwent McKeown three-incision esophagectomy with cervical anastomosis from January 2015 to December 2019 at Department of Minimally Invasive Esophageal Surgery, Tianjin Medical University Cancer Hospital and Institute were analyzed retrospectively. There were 876 males and 146 females, aging(M(IQR)) 48(16) years (range: 36 to 84 years). There were 253 patients (24.8%) with neoadjuvant therapy, and 817 patients (79.9%) with minimally invasive esophagectomy. According to the diagnosis and treatment habits of the attending surgeons, 333 patients were included in the RCE group, and RCE was performed on the 7th day postoperative, while 689 patients were included in the non-RCE group, and RCE was performed when the patients had suspicious symptoms. Taking clinical symptoms, RCE, CT, endoscopy and other methods as reference to the diagnosis of AL, the sensitivity and specificity were used to analyze and evaluate the efficacy of RCE for the diagnosis of AL. The data were compared by U test or χ² test between groups. Results: The incidence rate of AL after three-incision esophagectomy was 7.34% (75/1 022), including 30 cases in the RCE group and 45 cases in the non-RCE group (9.0%(30/333) vs. 6.5%(45/689), χ²=2.027, P=0.155). The diagnostic time of AL was 9(5) days postoperative (range: 4 to 30 days). Among them, 23 cases showed cervical leakages, 50 cases showed intro-thoracic leakages, and 2 cases both cervical and intro-thoracic leakages. The diagnostic time of patients with intro-thoracic leakages was longer than that of cervical leakages (10(4) days vs. 6(3) days, Z=-2.517, P=0.012). Among the 333 patients in the RCE group, 16 cases of RCE indicated leakages including 11 cases of true positive and 5 cases determined to be false positive, while 317 cases indicated no abnormalities including 19 cases developed leakages. The sensitivity and specificity of RCE to detect AL were 36.7%(11/30) and 98.3%(298/333), respectively. The Youden-index was 0.35, and the diagnostic accuracy was 92.8%(309/333). The positive and negative predictive value were 11/16 and 94.0%(298/317), respectively. Conclusions: Routine contrast esophagram after three-incision esophagectomy with cervical anastomosis has low sensitivity and high specificity in the diagnosis of AL. The diagnostic time of AL is the 9th day after surgery. It is necessary to prolong the observation time clinically, and combine RCE with CT, endoscopy and other inspection methods for diagnosis.

ABSTRACT

Objective: To compare the clinical efficacy and quality of life between uncut Roux-en-Y and Billroth II with Braun anastomosis in laparoscopic distal gastrectomy for gastric cancer patients. Methods: A retrospective cohort study was performed. Inclusion criteria: (1) 18 to 75 years old; (2) gastric cancer proved by preoperative gastroscopy, CT and pathological results and tumor was suitable for D2 radical distal gastrectomy; (3) postoperative pathological diagnosis stage was T1-4aN0-3M0 (according to the AJCC-7th TNM tumor stage), and the margin was negative; (4) Eastern Cooperative Oncology Group (ECOG) physical status score <2 points, and American Association of Anesthesiologists (ASA) grade 1 to 3; (5) no mental illness; (6) able to answer questionnaires independently; (7) patients agreed to undergo laparoscopic distal gastrectomy and signed an informed consent. Exclusion criteria: (1) patients with severe chronic diseases and American Association of Anesthesiologists (ASA) grade >3; (2) patients with other malignant tumors; (3) patients suffered from serious mental diseases; (4) patients received neoadjuvant chemotherapy or immunotherapy. According to the above criteria, clinical data of 200 patients who underwent laparoscopic distal gastrectomy at the Department of General Surgery of the First Affiliated Hospital of Army Medical University from January 2016 to December 2019 were collected. Of the 200 patients, 108 underwent uncut Roux-en-Y anastomosis and 92 underwent Billroth II with Braun anastomosis. The general data, intraoperative and postoperative conditions, complications, and endoscopic evaluation 1 year after the surgery were compared. Besides, the quality of life of two groups was also compared using the Chinese version of the European Organization For Research and Treatment of Cancer (EORTC) quality of life questionnaire-Core 30 (QLQ-C30) and quality of life questionnaire-stomach 22 (QLQ-STO22). Results: There were no significant differences in baseline data between the two groups (all P>0.05). All the 200 patients successfully underwent laparoscopic distal gastrectomy without intraoperative complications, conversion to open surgery or perioperative death. There were no significant differences between two groups in operative time, intraoperative blood loss, postoperative complications, time to flatus, time to removal of gastric tube, time to liquid diet, time to removal of drainage tube or length of postoperative hospital stay (all P>0.05). Endoscopic evaluation was conducted 1 year after surgery. Compared to Billroth II with Braun group, the uncut Roux-en-Y group had a significantly lower incidences of gastric stasis [19.8% (17/86) vs. 37.0% (27/73), χ(2)=11.199, P=0.024], gastritis [11.6% (10/86) vs. 34.2% (25/73), χ(2)=20.892, P<0.001] and bile reflux [1.2% (1/86) vs. 28.8% (21/73), χ(2)=25.237, P<0.001], and the differences were statistically significant. The EORTC questionnaire was performed 1 year after surgery, there were no significant differences in the scores of QLQ-C30 scale between the two groups (all P>0.05), while the scores of QLQ-STO22 showed that, compared to the Billroth II with Braun group, the uncut Roux-en-Y group had a lower pain score (median: 8.3 vs. 16.7, Z=-2.342, P=0.019) and reflux score (median: 0 vs 5.6, Z=-2.284, P=0.022), and the differences were statistically significant (all P<0.05), indicating milder symptoms. Conclusion: The uncut Roux-en-Y anastomosis is safe and reliable in laparoscopic distal gastrectomy, which can reduce the incidences of gastric stasis, gastritis and bile reflux, and improve the quality of life of patients after surgery.

ABSTRACT

The rate of sphincter-preserving surgery for mid-low rectal cancer is increasing, but anastomotic leakage remains to be one of the common serious complications after operation. How to reduce the morbility and mortality of anastomotic leakage is always a hot and difficult point in colorectal surgery. Protective ostomy is a common method to deal with the above problems in clinical practice. However, some problems such as inappropriate stoma and stoma-related complications etc. become the current clinical challenges. The purpose of this consensus focusing on indication of ostomy, clinical value, ostomy skills, prevention of stoma complications, reversion of stoma and stoma nursing aims to provide guidance for the clinical practice of protective ostomy in the operation of mid-low rectal cancer in China.

ABSTRACT

Advances in surgical techniques and treatment concept have allowed more patients with low rectal cancer to preserve sphincter without sacrificing survival benefit. However, postoperative dysfunctions such as fecal incontinence, frequency, urgency, and clustering often occur in patients with low rectal cancer. The main surgical procedures for low rectal cancer include low anterior rectum resection (LAR), intersphincteric resection (ISR), coloanal anastomosis (Parks) and so on. The incidence of major LARS after LAR is up to 84.6%. The postoperative function of ISR is even worse than LAR. Moreover, the greater the extent of resection ISR surgery, the worse the postoperative function. There are few studies on the function of Parks procedure. Current evidence suggests that the short-term function of Parks procedure is inferior to LAR, but function can gradually recovered over time. Colorectal surgeons have attempted to improve postoperative defecation by modifying bowel reconstructions. Current evidence suggests that J pouch or end-to-side anastomosis during LAR does not reduce the incidence of defecation disorders. Pouch reconstruction during ISR cannot reduce the incidence of severe LARS either. In general, the protection of postoperative defecation function in patients with low rectal cancer still has a long way to go.

ABSTRACT

Objective: To evaluate the influence of duodenal stump reinforcing on the short-term complications after laparoscopic radical gastrectomy. Methods: A retrospective cohort study with propensity score matching (PSM) was conducted. Clinical data of 1204 patients with gastric cancer who underwent laparoscopic radical gastrectomy at the First Affiliated Hospital of Army Medical University from April 2009 to December 2018 were collected. The digestive tract reconstruction methods included Billroth II anastomosis, Roux-en-Y anastomosis and un-cut-Roux- en-Y anastomosis. A linear stapler was used to transected the stomach and the duodenum. Among 1204 patients, 838 were males and 366 were females with mean age of (57.0±16.0) years. Duodenal stump was reinforced in 792 cases (reinforcement group) and unreinforced in 412 cases (non-reinforcement group). There were significant differences in resection range and anastomotic methods between the two groups (both P<0.001). The two groups were matched by propensity score according to the ratio of 1∶1, and the reinforcement group was further divided into purse string group and non-purse string group. The primary outcome was short-term postoperative complications (within one month after operation). Complications with Clavien-Dindo grade ≥ III a were defined as severe complications, and the morbidity of complication between the reinforcement group and the non-reinforcement group, as well as between the purse string group and the non-purse string group was compared. Results: After PSM, 411 pairs were included in the reinforcement group and the non-reinforcement group, and there were no significant differences in baseline data between the two groups (all P>0.05). No perioperative death occurred in any patient.The short-term morbidity of postoperative complication was 7.4% (61/822), including 14 cases of anastomotic leakage (23.0%), 11 cases of abdominal hemorrhage (18.0%), 8 cases of duodenal stump leakage (13.1%), 2 cases of incision dehiscence (3.3%), 6 cases of incision infection (9.8%) and 20 cases of abdominal infection (32.8%). Short-term postoperative complications were found in 25 patients (6.1%) and 36 patients (8.8%) in the reinforcement group and the non-reinforcement group, respectively, without significant difference (χ2=2.142, P=0.143). Nineteen patients (2.3%) developed short-term severe complications (Clavien-Dindo grade ≥IIIa), while no significant difference in severe complications was found between the two groups (1.7% vs. 2.9%, χ2=1.347, P=0.246). Sub-group analysis showed that the morbidity of short-term postoperative complication of the purse string group was 2.6% (9/345), which was lower than 24.2% (16/66) of the non-purse string group (χ2=45.388, P<0.001). Conclusion: Conventional reinforcement of duodenal stump does not significantly reduce the incidence of duodenal stump leakage, so it is necessary to choose whether to reinforce the duodenal stump individually, and purse string suture should be the first choice when decided to reinforce.

ABSTRACT

ABSTRACT Objective: To assess the functional outcomes and complications of modified Hautmann neobladder with Wallace ureteroileal anastomosis on a 6-8 cm long isoperistaltic chimney, following radical cystectomy. Materials and Methods: Between January 2015 and October 2019, 22 patients (18 men and 4 women) underwent radical cystectomy and Hautmann neobladder reconstruction with chimney modification and Wallace I ureteroileal anastomosis. The mean age of patients was 61 years (45-74 years). All procedures were performed by the same surgeon and the mean follow-up was 29.4 months. Complications were registered as early (occurring within 3 months) or late (occurring after 3 months), with particular attention addressed to the ureteroileal anastomotic stricture and anastomotic leakage rate. Patient evaluation also included symptom analysis for daytime continence and voiding frequency. Results: Ureteroileal anastomotic stricture was not detected as a cause of hydronephrosis. Hovewer, the anastomotic leakage occurred in one patient during the early postoperative period. Early complications occurred in 9 patients and the most common was bilateral hydronephrosis, detected in 5 examinees. Late complications occurred in 4 patients. Complete daytime and nighttime continence achieved in 18 and 16 patients respectively, with two patients (9%) still required intermittent catheterization three months after surgery. Conclusions: The functional results with modified Hautmann neobladder, incorporating short afferent limb in Wallace I uretero-enteric anastomosis, were efficient. This technique is an effective way to minimize potential uretero-enteric stricture, anastomotic leakage and incidence of vesicoureteral reflux.

ABSTRACT

The incidence of anastomotic leak after right hemicolectomy for cancer is relatively low, but it may be misjudged. In recent years, the results of some multi-center or nationwide registration studies in Europe have shown that the incidence of anastomotic leak is significantly higher than that of eastern countries. The reasons of these differences may be the different nature of the studies, the lack of rigor in diagnostic criteria or diagnostic methods, the difference in the level of specialization of hospitals or surgeons, and so on. Timely treatment of preoperative comorbidities, reasonable selection of preoperative bowel preparation and anastomotic technique/method might reduce the occurrence of anastomotic leak. The current evidence shows complete mesocolic excision (CME) does not increase the risk of anastomotic leak. The clinical features of ileo-colic anastomotic leak are different from those of rectal surgery. The mild cases can be treated conservatively, and the severe cases are suggested to receive timely diverting ileostomy.

ABSTRACT

Anastomotic leak is one of the most severe complications following right hemicolectomy but rarely happens, which should be diagnosed based on clinical manifestations, laboratory and radiographic examinations. Influencing factors of anastomotic leak after right hemicolectomy include bowel preparation, emergency surgery, anastomotic procedure (side-to-side anastomosis vs. end-to-side anastomosis, instrument anastomosis vs. manual technigue and intracorporeal vs. extracorporeal anastomosis), surgical resection range and patient's characteristics. The occurrence of anastomotic leak might be avoided by standardized operations and indocyanine green fluorescence imaging. Active treatment is recommended once anastomotic leak is diagnosed. Most patients can be cured by non-surgical treatments such as adequate drainage and anti-infection therapy. When severe sepsis happens or non-surgical treatment fails, surgical treatment should be carried out in time.

ABSTRACT

Resumen Introducción: Una complicación importante de la cirugía colorrectal es la dehiscencia de anastomosis (DA). El estado nutricional es uno de los factores importantes en la DA. Una forma objetiva para evaluar nutricionalmente a los pacientes es medir la sarcopenia, definida como disminución de masa muscular esquelética, que puede ser objetivada por análisis de Unidades Hounsfield (UH) y área muscular (AM) por medio de Tomografía Computarizada de Abdomen y Pelvis (TCAP). Objetivo: Evaluar si existe relación entre la DA y la presencia de sarcopenia detectada por medición de UH y AM en TCAP en pacientes sometidos a colectomía por cáncer. Materiales y Método: Estudio de casos y controles con estadística analítica. Se eligen de manera aleatoria 21 pacientes con DA y 40 sin DA. Se incluyen > 18 años, con colectomía por cáncer y anastomosis primaria. Fueron excluidos pacientes ostomizados, que no tuvieran TCAP preoperatoria o que éste no permitiera medir UH y AM. La evaluación imagenológica fue realizada por radiólogo experto. Resultados: La comparación entre grupos evidencia que son homogéneos con respecto al sexo (predomino hombres), edad (promedio 60 años) y localización. Se evidencia signos imagenológicos sugerentes de sarcopenia en el grupo de DA, puesto que existe disminución en UH con valores estadísticamente significativos y tendencia a presentar valores menores en el AM. Conclusiones: La presencia de sarcopenia evaluada por alteración de UH en estudio radiológico se correlaciona con DA, pudiendo ser un predictor de riesgo. La importancia de este hallazgo es que es un factor de riesgo potencialmente corregible.


Introduction: An important complication of colorectal surgery is anastomotic dehiscence (AD). Nutritional status is one of the important factors in AD. An objective way to evaluate the patients' nutritional status is to measure sarcopenia, which is the reduction of skeletal muscle mass. It is possible to standardize Sarcopenia using the analysis of the Hounsfield Units (HU) and the muscular area (MA) which consider Computed Tomography of Abdomen and Pelvis (CTAP). Aim: To evaluate whether there is a relationship between AD and the presence of sarcopenia detected by the measurement of HU and MA using CTAP. The situation considers patients undergoing colectomy for cancer. Materials and Method: Cases and controls were studied with analytical statistics. 21 patients with AD and 40 without AD were chosen randomly. They include > 18 years, with colectomy for cancer and primary anastomosis. Ostomized patients, who previous the surgery do not have CTAP or if it was not available to measure HU and MA, were excluded. The imaging evaluation was performed by an expert radiologist. Results: The comparison between groups shows that they are homogeneous with respect the sex (predominant men), age (average 60 years) and location. There are signs of imaging which suggest the presence of sarcopenia in the AD group. This is explained because there is an important statistical decrease in the HU values and a tendency to present lower MA values. Conclusions: The presence of sarcopenia due to alteration of HU in a radiological study is correlated with AD, and could be a predictor of risk. The importance of this finding is that this risk factor is potentially correctable.
