Functional Outcomes and Quality of Life After Transanal Total Mesorectal Excision for Rectal Cancer: A Prospective Observational Study.

BACKGROUND: Few studies have addressed the functional impact after transanal total mesorectal excision. OBJECTIVE: This study aimed to evaluate function and health-related quality of life among patients with rectal cancer treated with transanal total mesorectal excision. DESIGN: Consecutive patients treated between 2016 and 2018 were selected. Their function and quality of life were studied preoperatively and at 3 and 12 months after surgery. SETTING: This is a prospective case series. PATIENTS: Patients were eligible if they had primary anastomosis, their diverting stoma had been reversed, and they did not have anastomotic leakage. Forty-five patients were finally included. A total of 31 (68.8%) and 32 patients (71.1%) completed the 3- and 12-month surveys. INTERVENTIONS: Standard transanal total mesorectal excision was performed. MAIN OUTCOME MEASURES: The primary end point was functional and quality-of-life outcomes using validated questionnaires. Secondary end points included values obtained with endoanal ultrasounds, anorectal manometries, and rectal sensation testing. RESULTS: Wexner and Low Anterior Resection Syndrome scores significantly increased 3 months after surgery but returned to baseline values at 12 months. The rate of "major low anterior resection syndrome" at the end of follow-up was 25.0% (+11.7% compared with baseline, p = 0.314). Sexual and urinary functions remained stable throughout the study, although a meaningful clinical improvement was detected in male sexual interest. Among quality-of-life domains, all deteriorations returned to baseline values 12 months after surgery, except worsening of flatulence symptoms, and improvement in insomnia and constipation. At 12 months, an expected decrease in the mean width of the internal sphincter, the anal resting pressure, and the tenesmus threshold volume was found. LIMITATIONS: This study was limited by its small sample size, the absence of a comparative group, and significant missing data in female sexual difficulty and in ultrasounds and manometries at 3 months. CONCLUSIONS: Patients undergoing transanal total mesorectal excision report acceptable quality-of-life and functional outcomes 12 months after surgery.

Performance of Indocyanine-Green Imaging for Sentinel Lymph Node Mapping and Lymph Node Metastasis in Esophageal Cancer: Systematic Review and Meta-Analysis.

BACKGROUND AND OBJECTIVES: Lymphatic mapping with indocyanine-green (ICG) and near-infrared light fluorescent imaging is widely used for sentinel lymph node staging in different types of cancer but is not fully accepted for all procedures because studies have reported heterogeneous results. This study aimed to assess the detection rate (DR) of ICG imaging for sentinel lymph node mapping (SLNM) and lymph node metastases (LNMs) in esophageal cancer. METHODS: A systematic search was performed to identify relevant studies examining the use of ICG imaging for SLNM in patients with esophageal cancer. Extracted results were pooled in a single-proportion meta-analysis, with a random-effects model, presented as forest plots. RESULTS: Six studies were included in the analysis. The ICG DR for SLNM was 89% [95% confidence interval (CI) 71%-96%]. The pooled sensitivity and specificity values for the detection of LNMs were 84% (95% CI 64%-94%) and 15% (95% CI 3%-45%), respectively. A trend towards a lower DR was found with increasing mean latency time between ICG injection and SLNM. CONCLUSIONS: ICG imaging is a technique that potentially could improve lymph node yield excision and, as a consequence, improve the detection of lymph node metastases.

Clinical, Anatomical, and Pathological Grading Score to Predict Technical Difficulty in Laparoscopic Splenectomy for Non-traumatic Diseases.

BACKGROUND: We aimed to develop a grading system based on preoperative parameters that would predict surgical difficulty and morbidity in elective laparoscopic splenectomy. STUDY DESIGN: We retrospectively assessed morbidity in 439 patients who underwent laparoscopic splenectomy for benign and malignant disorders between 1993 and 2013. Medical and surgical records were reviewed and analyzed. We compared preoperative data concerning demographic, clinical, pathological, anatomical, laboratory, and radiological factors with three surgical outcomes: operative time, intraoperative bleeding, and surgical conversion. Univariate and multivariate analyses were performed to identify statistically significant variables. A logistic regression model was used to identify determinant variables and to compose a predictive score. External validation of the score was performed using an independent cohort of 353 patients. RESULTS: Four preoperative parameters (age, male sex, type of pathology, and spleen size based on final spleen weight) were significantly related with operative time, operative bleeding, and conversion to open surgery. Using these results, we developed a classification system with three levels of difficulty: low (≤4 points), medium (4.5-5.5 points), and high (≥6 points), based on the four preoperative parameters. The correlation was highly significant (p = <0.001) according to Spearman's correlation. The area under the ROC curve was 0.671 (95 % CI 0.596-0.745). The external validation showed significant correlations with the present model. CONCLUSIONS: The grading score described here is simple to calculate from the physical examination, laboratory tests, and US or CT images, and we believe it could be useful to preoperatively assess the technical complexity of laparoscopic splenectomy.

Impacto del recuento plaquetario preoperatorio en la evolución perioperatoria tras la esplenectomía laparoscópica por púrpura trombocitopénica idiopática / Impact of preoperative platelet count on perioperative outcome after laparoscopic splenectomy for idiopathic thrombocytopenic purpura

INTRODUCCIÓN: La esplenectomía laparoscópica (EL) es el tratamiento de elección de la púrpura trombocitopénica idiopática (PTI) cuando fracasa el tratamiento médico. El objetivo de este estudio ha sido evaluar la factibilidad y seguridad de la EL según el recuento preoperatorio de plaquetas. MÉTODOS: Análisis retrospectivo de una serie de 199 pacientes a los que se les realizó una EL por PTI durante el periodo 1993-2015. Los pacientes se dividieron en 3 grupos según las cifras de plaquetas: grupo I (< 10 × 109 /L), grupo II (10-50 × 109/L) y grupo III(>50 × 109/L). RESULTADOS: El tiempo operatorio fue significativamente menor en el grupo III respecto a los grupos I y II(100 ± 53 y 105 ± 61min; p < 0,025). La pérdida hemática intraoperatoria fue estadísticamente superior en el grupo I (263 ± 551 ml) respecto a los otros 2: grupo II (128 ± 352ml) y grupo III (24 ± 62 ml) (p < 0,003). La estancia hospitalaria de 6,4±5,8 días en el grupo I fue significativamente superior a la de los grupos II y III (3,8±2,3 y 3,2±1,8 días, respectivamente; p < 0,003). CONCLUSIONES: La realización de una EL en pacientes con PTI con recuentos bajos es efectiva y segura

INTRODUCTION: Laparoscopic splenectomy (LS) is the preferred treatment of idiopathic thrombocytopenic purpura (ITP) when medical treatment fails. The objective was to evaluate the feasibility and safety of LS according to the preoperative platelet count. METHODS: This study is a retrospective analysis of a series of 199 patients who underwent LS for ITP from 1993 to 2015. The patients were divided into 3 groups according to platelet count: group I(< 10 × 109/L), group II (10-50 × 109/L) and group III (> 50 × 109/L). RESULTS: Operative time was significantly lower in Group III compared to Group I and II (100 ± 53 and 105 ± 61min, P < .025)). Intraoperative blood loss was statistically higher in group I (263 ± 551ml) with respect to the other 2: group II (128 ± 352 ml) and group III (24 ± 62 ml) (P < .003). Hospital stay was 6.4 ± 5.8 days in group I, significantly higher compared to groups II and III(3.8 ± 2.3 and 3.2 ± 1.8 days, respectively (P < .003)). CONCLUSION: Conducting a LS in ITP patients with low platelet counts is effective and safe

Are there differences between right and left colectomies when performed by laparoscopy?

BACKGROUND: There is an extended belief that the laparoscopic approach to left colectomy (LC) is technically more demanding and associated with more postoperative complications than to right colectomy (RC). However, there is no consensus in the literature about whether the short-term outcomes of RC differ from those of LC. The aim of this paper was to compare the postoperative course of patients undergoing RC and LC. METHODS: We retrospectively analyzed 1000 consecutive patients who underwent a laparoscopic RC or LC between 1998 and 2012. Factors analyzed were intraoperative complications, surgical time, postoperative complications, and length of stay. The two groups were divided into four subgroups (neoplasia, diverticular disease, polyps, and others). RESULTS: LC was associated with more postoperative complications than RC and longer operative time both in the two main groups (postoperative complications 30 vs. 19%; operative time 139 vs. 118 min) and in the neoplasia subgroups (27 vs. 18%; 137 vs. 118 min). No differences between groups were found for rates of reintervention or death. Comparison between LC subgroups showed that the operative time was longer and the conversion rate was higher in the diverticular disease subgroup than in the neoplasia subgroup (155 vs. 137 min; 21 vs. 8%). CONCLUSIONS: In this large cohort of patients undergoing laparoscopic colectomy, LC carried a higher risk than RC of postoperative complications. These findings provide new data on the differences between the two surgeries. Our findings strengthen the notion that right and left colectomies have a different intraoperative and postoperative course and should be analyzed as two separate entities.

¿Qué operan los residentes españoles durante la residencia?: análisis de la aplicabilidad del programa de la especialidad de Cirugía General y Digestiva al finalizar el periodo de residencia / The surgical experience of general surgery residents: An analysis of the applicability of the specialty program in General and Digestive Surgery

El entrenamiento quirúrgico siguiendo un periodo de residencia ha conseguido que los residentes en nuestro país posean una formación homogénea y satisfactoria para el desarrollo de su actividad profesional. Ello se debe a la existencia de planes de formación específicos para cada especialidad. El plan vigente promulgado en 2007 detallaba el número mínimo de intervenciones quirúrgicas y procedimientos que un cirujano debía haber efectuado para completar su periodo de formación. El objetivo de este estudio es conocer la aplicación del programa de la especialidad en cuanto al número de intervenciones practicadas durante el periodo de residencia. MATERIAL Y MÉTODOS: Se diseñó una hoja de recogida de datos que incluía la relación de intervenciones enunciada en el programa de la especialidad, que fue remitida en abril de 2014 a todos los hospitales que disponen de unidades acreditadas para la formación de residentes. En septiembre de 2014 se tabularon las respuestas remitidas y se efectuó un estudio estadístico descriptivo general, y un subanálisis en función del sexo del residente y de la comunidad autónoma. A la vez se analizó la actividad efectuada en función del número de residentes que existiera en cada unidad docente acreditada. RESULTADOS: La encuesta se remitió a los 117 hospitales con unidades acreditadas, que incluyen un total de 190 plazas ofertadas. De ellas se obtuvieron 91 respuestas (53%). La formación ofrecida se adapta en líneas generales a la propuesta por el plan de la especialidad. El número global de intervenciones practicadas de acuerdo a las diferentes subáreas, en cirugía laparoscópica y de urgencias, cumple o supera las cifras previstas, excepto en cirugía esofagástrica y HPB. El subanálisis de la actividad quirúrgica según la comunidad autónoma no evidencia diferencias significativas en el número total de intervenciones, sin embargo, sí se objetivan diferencias en cirugía endocrina (p = 0,001) y de la mama (p = 0,042). Un 55% de los residentes eran mujeres, sin diferencias significativas en cuanto a su distribución en las comunidades autónomas. Sin embargo, las cirujanas operan más que los cirujanos durante la residencia (625 ± 244 vs 527 ± 209; p < 0,01). También se observa que el número de residentes adscrito a cada unidad docente se correlaciona con el número de intervenciones realizadas: han efectuado más intervenciones los cirujanos que están solos en su unidad que aquellos que tienen compañeros de su mismo año (669 ± 237 vs. 527 ± 209; p = 0,004). CONCLUSIÓN: La actividad quirúrgica efectuada por los cirujanos españoles se adecua a la propuesta por el plan actual de la especialidad, excepto en cirugía HPB y esofagogástrica. La distribución es homogénea de acuerdo a las comunidades autónomas, aunque existen diferencias en función del número de residentes por hospital y el sexo del residente. Esta información es esencial para evaluar la idoneidad del plan de formación y el diseño de nuevos planes formativos

Residents in our country have achieved a homogenous surgical training by following a structured residency program. This is due to the existence of specific training programs for each specialty. The current program, approved in 2007, has a detailed list of procedures that a surgeon should have performed in order to complete training. The aim of this study is to analyze the applicability of the program with regard to the number of procedures performed during the residency period. MATERIAL AND METHODS: A data collection form was designed that included the list of procedures from the program of the specialty; it was sent in April 2014 to all hospitals with accredited residency programs. In September 2014 the forms were analysed, and a general descriptive study was performed; a subanalysis according to the resident's sex and Autonomous region was also performed. The number of procedures performed according to the number of residents in the different centers was also analyzed. RESULTS: The survey was sent to 117 hospitals with accredited programs, which included 190 resident places. A total of 91 hospitals responded (53%). The training offered adapts in general to the specialty program. The total number of procedures performed in the different sub-areas, in laparoscopic and emergency surgery is correct or above the number recommended by the program, with the exception of esophageal-gastric and hepatobiliary surgery. The sub-analysis according to Autonomous region did not show any significant differences in the total number of procedures, however, there were significant differences in endocrine surgery (P = .001) and breast surgery (P = .042). A total of 55% of residents are female, with no significant differences in distribution in Autonomous regions. However, female surgeons operate more than their male counterparts during the residency period (512 ± 226 vs. 625 ± 244; P < .01). The number of residents in the hospital correlates with the number of procedures performed; the residents with more procedures trained in hospitals where there were less residents (669 ± 237 vs. 527 ±2 09; P = .004). CONCLUSION: The surgical activity performed by spanish surgeons is adequate to the specialty program, except in hepatobiliary and esophageal-gastric surgery. The distribution is homogeneous in the different autonomous regions, although there are differences that depend on the number and sex the of residents in each hospital. This information is essential to evaluate the quality of the specialty program and to design new training programs
