Long-term outcomes of transanal total mesorectal excision for rectal cancer: what could we do to improve them?

BACKGROUND: Long-term outcomes of transanal mesorectal excision are still controversial. The aim of this study was to analyze long-term oncological and functional results of TaTME. METHODS: Fifty patients with mid-low rectal cancer were included: 20 underwent TaTME and 30 laparoscopic total mesorectal excision. Clinical characteristics of patients and tumors and quality indicators for rectal surgery were described. Long-term functional outcomes were compared in two groups (TaTME vs. laTME). Local recurrence rate was calculated. Kaplan-Meier curves were performed for disease-free and overall survival and log-rank test was used to compare two groups. RESULTS: There were not significant differences between two groups in sex, age ASA Score, neoadjuvant therapy, tumor stage and quality indicators of rectal surgery. After a median follow-up of 46 (41-51) months functional outcomes were significantly worse in TaTME group in terms of rates of maior low anterior resection syndrome score (10% vs. 0%, P=0.009), faucal incontinence (15% vs. 3%, P=0.017), urinary disfunction (10% vs. 0%, P=0.009) and sexual disfunction (15% vs. 13%, P=0.047). Only one patient presented local recurrence (TaTME group, ypT3N0). Overall survival at 1 and 3 years were 92.6% and 90% respectively and disease-free survival at 1 and 3 years were 96% and 90% respectively. There were not significant differences in overall survival and disease-free survival between two groups. CONCLUSIONS: Overall survival and disease-free survival after TaTME for rectal cancer were similar to laparoscopic total mesorectal excision. However functional outcomes were worse after TaTME.

Mechanical triangular esophagogastrostomy: Technical aspects and initial results.

INTRODUCTION: Esophageal cancer represents the eighth neoplasm worldwide. The therapeutic approach is interdisciplinary, with surgery being the most effective option. Several techniques have been proposed to perform esophagogastrostomy after esophagectomy, among them mechanical triangular esophagogastrostomy (MT), with a little experience published in the Western literature on the latter. The objective of this study is to describe the technical aspects and initial results of MT anastomosis. METHODS: A retrospective review of the patients who underwent esophagectomy according to the McKeown technique was performed, those in which MT anastomosis was implemented, between October 2017 and March 2020 in our hospital. RESULTS: 14 patients were included, with a mean age of 63 years. The mean operative time was 436 min (360-581), being diagnosed of anastomotic leak (AL) 3 of the 14 patients (21.4%), as well as 3 patients presented anastomotic stenosis (AS). The median stay was 20 days, without any death in the series. DISCUSSION: Multiple publications suggest the superiority in terms of AL and AS of the mechanical triangular anastomosis, which was also observed in our series, in which despite the small sample, a rapid improvement was observed in the indicators after the first cases. Therefore, this type of anastomosis may be a safe option for performing esophagogastric anastomosis after esophagectomy, being necessary more definitive conclusive studies.

Esofagogastrostomía triangular mecánica: aspectos técnicos y resultados iniciales / Mechanical triangular esophagogastrostomy: Technical aspects and initial results

IntroducciónEl cáncer de esófago representa la octava neoplasia a nivel mundial. El abordaje terapéutico es interdisciplinar y la cirugía es la opción más eficaz. Se han planteado varias técnicas para la realización de la esofagogastrostomía posterior a la esofagectomía, entre ellas, la esofagogastrostomía triangular mecánica, con muy poca experiencia publicada en la literatura occidental. El objetivo de este estudio es describir los aspectos técnicos y los resultados iniciales de la instauración de anastomosis triangular mecánica.MétodosSe realizó una revisión retrospectiva de los pacientes tratados mediante esofaguectomía según la técnica de McKeown, en los cuales se realizó anastomosis triangular mecánica entre octubre de 2017 y marzo de 2020 en nuestro hospital.ResultadosFueron incluidos 14 pacientes, con una media de edad de 63 años. El tiempo operatorio promedio fue de 436 min (360-581); fueron diagnosticados de fuga anastomótica 3 de los 14 pacientes (21,4%) y otros 3 pacientes presentaron estenosis anastomótica. La mediana de estancia fue de 20 días, sin ningún fallecimiento en la serie.ConclusionesMúltiples publicaciones señalan la superioridad en términos de fuga anastomótica y estenosis anastomótica de la anastomosis triangular mecánica. Esto también se observa en nuestra serie, en la cual, a pesar de lo reducido de la muestra, se observó una rápida mejoría en los indicadores posterior a los primeros casos, por lo que este tipo de anastomosis puede ser una opción segura para la confección de la anastomosis esofagogástrica posterior a la esofaguectomía. Son necesarios más estudios para alcanzar conclusiones definitivas (AU)

Quality indicators of transanal total mesorectal excision (TaTME) for rectal cancer

Introduction: Transanal total mesorectal excision (TaTME) has revolutionized the surgical techniques for lower-third rectal cancer. The aim of the present study was to analyze the outcomes of quality indicators of TaTME for rectal cancer compared with laparoscopic TME (LaTME). Methods: A cohort prospective study with 50 (14 female and 36male) patients, with a mean age of 67 (range: 55.75 to 75.25) years, who underwent surgery for rectal cancer. In total, 20 patients underwent TaTME, and 30, LaTME. Every TaTME procedure was performed by experienced colorectal surgeons. The sample was divided into two groups (TaTME and LaTME), and the quality indicators of the surgery for rectal cancer were analyzed. Results: There were no statistically significant differences regarding the patients and the main characteristics of the tumor (age, gender, American Society of Anesthesiologists [ASA] score, body mass index [BMI], tumoral stage, neoadjuvant therapy, and distance from the tumor to the external anal margin) between the two groups. The rates of: postoperativemorbidity (TaTME: 35%; LaTME: 30%; p=0.763);mortality (0%); anastomotic leak (TaTME: 10%; LaTME: 13%; p=0.722); wound infection (TaTME: 0%; LaTME: 3.3%; p=0.409); reoperation (TaTME: 5%; LaTME: 6.6%; p=0.808); and readmission (TaTME: 5%; LaTME: 0%; p=0.400), as well as the length of the hospital stay (TaTME: 13.5 days; LaTME: 11 days; p=0.538), were similar in both groups. There were no statistically significant differences in the rates of positive circumferential resection margin (TaTME: 5%; LaTME: 3.3%; p=0.989) and positive distal resection margin (TaTME: 0%; LaTME: 3.3%; p=0.400), the completeness of the TME (TaTME: 100%; LaTME: 100%), and the number of lymph nodes harvested (TaTME: 15; LaTME: 15.5; p=0.882) between two groups. Conclusion: Transanal total mesorectal excision is a safe and feasible surgical procedure for middle/lower-third rectal cancer. (AU)

Impact of the Covid-19 pandemic on colorectal cancer surgery in Madrid

Introduction: The Covid-19 pandemic has had an important impact on colorectal cancer surgery, for hospital resources had to be redistributed in favour of Covid-19 patients. The aim of the present study is to analyze our results in colorectal oncologic surgery during the Covid-19 pandemic in patients with and without perioperative SARSCoV- 2 infection. Methods: In total, 32 patients (19 male and 13 female patients), with a mean age of 64 years (range: 57.2 to 69.5 years) with colorectal cancer underwent surgery under the recommendations of surgical societies included in a protocol. Data collection included clinical characteristics (gender, age, body mass index, American Society of Anesthesiologists score, tumor location, preoperative staging, lymphopenia), data related to SARS-CoV-2 infection (postoperative symptoms, diagnostic tests), operative details (surgical procedure, approach, duration, stoma), pathological outcomes (tumor stage, number of lymph nodes harvested, distal and circumferential radial margins, quality of the total mesorectal excision), and surgical outcomes (morbidity, mortality, hospital stay, and the rates of reoperation and readmission). Results: A total of 3 (9.4%) patients who underwent colorectal surgery during the Covid-19 pandemic were infected by SARS-CoV-2 in the postoperative period. Chronic obstructive pulmonary disease was associated with Covid-19 (6.2% versus 33.3%; p=0.042), and surgical morbidity was higher among Covid-19 patients (100% versus 37.9%; p=0.039). There were not significant differences between COVID-19 patients and non-COVID-19 patients in relation to the rest of the analyzed outcomes. Conclusion: During the Covid-19 pandemic, colorectal cancer surgery should be performed according to the recommendations of surgical societies. However, Covid- 19 patients could present a higher morbidity rate. (AU)

Liver transplant in a receptor with ABO incompatibility: a viable option.

We present the case of a 41-year-old male with type A blood group and a diagnosis of fulminant liver failure of an unknown cause, who was admitted to the Intensive Care Unit (ICU) with severe coagulopathy (INR 6), hyperammonemia (250 umol/l) and grade IV encephalopathy (four King's criteria and both Clichy's criteria). He also had GCS 8/15, despite TDE-MARS, dialysis and ventilator support via endotracheal tube due to encephalopathy. He was registered as status 0 for liver transplant. In the absence of a compatible donor, the patient received an ABO incompatible liver transplant (LT), group O, using the piggyback technique, without any complications. He required transfusion of five units of plasma but did not require a blood transfusion.
