Transanal total mesorectal excision for rectal cancer has been suspended in Norway.

BACKGROUND: Transanal total mesorectal excision (TaTME) for rectal cancer has emerged as an alternative to the traditional abdominal approach. However, concerns have been raised about local recurrence. The aim of this study was to evaluate local recurrence after TaTME. Secondary aims included postoperative mortality, anastomotic leak and stoma rates. METHODS: Data on all patients who underwent TaTME were recorded and compared with those from national cohorts in the Norwegian Colorectal Cancer Registry (NCCR) and the Norwegian Registry for Gastrointestinal Surgery (NoRGast). Kaplan-Meier estimates were used to compare local recurrence. RESULTS: In Norway, 157 patients underwent TaTME for rectal cancer between October 2014 and October 2018. Three of seven hospitals abandoned TaTME after a total of five procedures. The local recurrence rate was 12 of 157 (7·6 per cent); eight local recurrences were multifocal or extensive. The estimated local recurrence rate at 2·4 years was 11·6 (95 per cent c.i. 6·6 to 19·9) per cent after TaTME compared with 2·4 (1·4 to 4·3) per cent in the NCCR (P < 0·001). The adjusted hazard ratio was 6·71 (95 per cent c.i. 2·94 to 15·32). Anastomotic leaks resulting in reoperation occurred in 8·4 per cent of patients in the TaTME cohort compared with 4·5 per cent in NoRGast (P = 0·047). Fifty-six patients (35·7 per cent) had a stoma at latest follow-up; 39 (24·8 per cent) were permanent. CONCLUSION: Anastomotic leak rates after TaTME were higher than national rates; local recurrence rates and growth patterns were unfavourable.

ANTECEDENTES: La resección total del mesorrecto transanal (transanal total mesorectal excision, TaTME) para el cáncer de recto se ha propuesto como una alternativa al abordaje abdominal tradicional. Sin embargo, la recidiva local (local recurrence, LR) después de este procedimiento es motivo de preocupación. El objetivo de este estudio fue evaluar la LR en pacientes operados mediante TaTME. Los objetivos secundarios incluyeron la mortalidad postoperatoria, las fugas anastomóticas y el porcentaje de estomas. MÉTODOS: Se registraron los datos de todos los pacientes operados mediante TaTME y se compararon con las cohortes nacionales del Registro Noruego de Cáncer Colorrectal (Norwegian Colorectal Cancer Registry, NCCR) y del Registro Noruego de Cirugía Gastrointestinal (Norwegian Registry for Gastrointestinal Surgery, NoRGast) utilizando estimaciones de Kaplan-Meier y la prueba de log-rank para comparar curvas de LR. RESULTADOS: En Noruega, 157 pacientes se sometieron a TaTME por cáncer de recto entre octubre de 2014 y octubre de 2018. Tres de siete hospitales abandonaron el TaTME después de un total de cinco procedimientos. La LR observada fue 12/157 (7,6%), siendo ocho de ellas multifocales o extensas. La tasa estimada de LR a 2,4 años fue de 11,6 % (i.c. del 95% 6,6 a 19,9) versus 2,4 % (1,4 a 4,3) en el NCCR (log rank P < 0,001). El cociente de riesgos instantáneos (hazard ratio, HR) ajustado fue 6,7 (i.c. del 95% 2,9 a 15,3). Las fugas anastomóticas que precisaron una reintervención después de TaTME ocurrieron en un 8,4% versus 4,5% en el registro NoRGast (P = 0,047). Cincuenta y seis pacientes (35,7%) tenían un estoma en el último seguimiento; 39 (24,8%) eran permanentes. CONCLUSIÓN: Las tasas de fuga anastomótica tras una TaTME fueron más altas que los datos nacionales con tasas de LR y patrones de crecimiento desfavorables.

Risk Factors for Complications following Introduction of Radical Surgery for Colon Cancer: A Consecutive Patient Series.

BACKGROUND: Rectal cancer surgery is standardized, resulting in improved survival. Colon cancer has fallen behind and therefore more radical surgical techniques have been introduced. One technique is complete mesocolic excision. The aim of this article was to study the complications after the introduction of standardized complete mesocolic excision in a single center. METHODS: Complete mesocolic excision was introduced in 2007, and data were collected from 286 patients prior to surgery (2007-2010). The surgeon decided on open or laparoscopic surgery. Follow-up information was recorded until 31 December 2015. Complications were classified according to a modified Clavien-Dindo classification. RESULTS: Complications occurred in 47%, severe complications (grade III and IV) in 15%. In-hospital mortality was 3.5%. A total of 142 patients (49.7%) were operated by open surgery. Logistic regression revealed anemia (p = 0.001), open surgery (p < 0.001), and long operating time (p < 0.001) as significant factors for complications in general. Multinomial logistic regression revealed that severe complications occurred more often in males (odds ratio: 2.56; 95% confidence interval: 0.98-6.68), patients with anemia (odds ratio: 3.49; 95% confidence interval: 1.27-9.60), elevated body mass index (odds ratio: 1.14; 95% confidence interval: 1.02-1.28), and in open surgery (odds ratio: 9.95; 95% confidence interval: 2.58-38.35). Age was not associated with severe complications. Survival was not significantly influenced by complications. Overall survival (5 years) was 90% among patients with complications and 92% among those without complications. CONCLUSION: Severe complications following the introduction of complete mesocolic excision are patient dependent and related to open surgery. Patients selected for laparoscopy had less number of complications; therefore, introducing complete mesocolic excision by laparoscopy is justified. Identification of these factors can improve selection of appropriate surgical approach and postoperative patient safety.

One-year results of the SCANDIV randomized clinical trial of laparoscopic lavage versus primary resection for acute perforated diverticulitis.

BACKGROUND: Recent randomized trials demonstrated that laparoscopic lavage compared with resection for Hinchey III perforated diverticulitis was associated with similar mortality, less stoma formation but a higher rate of early reintervention. The aim of this study was to compare 1-year outcomes in patients who participated in the randomized Scandinavian Diverticulitis (SCANDIV) trial. METHODS: Between February 2010 and June 2014, patients from 21 hospitals in Norway and Sweden presenting with suspected perforated diverticulitis were enrolled in a multicentre RCT comparing laparoscopic lavage and sigmoid resection. All patients with perforated diverticulitis confirmed during surgery were included in a modified intention-to-treat analysis of 1-year results. RESULTS: Of 199 enrolled patients, 101 were assigned randomly to laparoscopic lavage and 98 to colonic resection. Perforated diverticulitis was confirmed at the time of surgery in 89 and 83 patients respectively. Within 1 year after surgery, neither severe complications (34 versus 27 per cent; P = 0·323) nor disease-related mortality (12 versus 11 per cent) differed significantly between the lavage and surgery groups. Among the 144 patients with purulent peritonitis, the rate of severe complications (27 per cent (20 of 74) versus 21 per cent (15 of 70) respectively; P = 0·445) and disease-related mortality (8 versus 9 per cent) were similar. Laparoscopic lavage was associated with more deep surgical-site infections (32 versus 13 per cent; P = 0·006) but fewer superficial surgical-site infections (1 versus 17 per cent; P = 0·001). More patients in the lavage group underwent unplanned reoperations (27 versus 10 per cent; P = 0·010). Including stoma reversals, a similar proportion of patients required a secondary operation (28 versus 29 per cent). The stoma rate at 1 year was lower in the lavage group (14 versus 42 per cent in the resection group; P < 0·001); however, the Cleveland Global Quality of Life score did not differ between groups. CONCLUSION: The advantages of laparoscopic lavage should be weighed against the risk of secondary intervention (if sepsis is unresolved). Assessment to exclude malignancy (although uncommon) is advised. Registration number: NCT01047462 ( http://www.clinicaltrials.gov).

Pre- and postoperative stoma education and guidance within an enhanced recovery after surgery (ERAS) programme reduces length of hospital stay in colorectal surgery.

INTRODUCTION: Stoma formation delays discharge after colorectal surgery. Stoma education is widely recommended, but little data are available regarding whether educational interventions are effective. The aim of this prospective study was to investigate whether an enhanced recovery after surgery (ERAS) programme with dedicated ERAS and stoma nurse specialists focusing on counselling and stoma education can reduce the length of hospital stay, re-admission, and stoma-related complications and improve health-related quality of life (HRQoL) compared to current stoma education in a traditional standard care pathway. METHODS: In a single-center study 122 adult patients eligible for laparoscopic or open colorectal resection who received a planned stoma were treated in either the ERAS program with extended stoma education (n = 61) or standard care with current stoma education (n = 61). The primary endpoint was total postoperative hospital stay. Secondary endpoints were postoperative hospital stay, major or minor morbidity, early stoma-related complications, health-related quality of life, re-admission rate, and mortality. HRQoL was measured by the generic 15D instrument. RESULTS: Total hospital stay was significantly shorter in the ERAS group with education than the standard care group (median [range], 6 days [2-21 days] vs. 9 days [5-45 days]; p < 0.001). Regarding overall major and minor morbidity, re-admission rate, HRQoL, stoma-related complications and 30-day mortality, the two treatment groups exhibited similar outcomes. CONCLUSION: Patients receiving a planned stoma can be included in an ERAS program. Pre-operative and postoperative stoma education in an enhanced recovery programme is associated with a significantly shorter hospital stay without any difference in re-admission rate or early stoma-related complications.

Compliance with enhanced recovery after surgery criteria and preoperative and postoperative counselling reduces length of hospital stay in colorectal surgery: results of a randomized controlled trial.

AIM: The aim of this randomized clinical trial was to compare patients treated using a multimodal approach [enhanced recovery after surgery (ERAS)], with a special focus on counselling, to patients treated in a standard conventional care pathway, who underwent elective colorectal resection. METHOD: In a single-centre trial, adult patients eligible for open or laparoscopic colorectal resection were randomized to an ERAS programme or standard care. The primary end-point was postoperative total hospital stay. Identical discharge criteria were defined for both treatment groups. Secondary end-points included postoperative complications, postoperative C-reactive protein levels, postoperative hospital stay, readmission rate and mortality. All parameters were recorded before operation, on the day of surgery and daily thereafter until discharge. RESULTS: Total hospital stay was significantly shorter among patients randomized to ERAS than among the standard group [median 5 days (range 2-50 days) vs median 8 days (range 2-48 days); P = 0.001]. The two treatment groups exhibited similar outcomes regarding overall major and minor morbidity, reoperation rate, readmission rate and 30-day mortality. There were also no differences in tolerance of enteral nutrition or in the inflammatory response, as reflected by postoperative C-reactive protein levels. CONCLUSION: ERAS care was associated with a significantly shorter length of hospital stay. Without any difference in surgical or general complications, tolerance of enteral nutrition or postoperative C-reactive protein levels, peri-operative information and guidance for ensuring that patients comply with the ERAS approach appear to be important factors to reduce the length of hospital stay.
