BACKGROUND: A more extensive resection is often required in locally advanced rectal cancer, depending on preoperative neoadjuvant treatment response. OBJECTIVE: Circumferential margin involvement and postoperative outcomes after total mesorectal excision and multivisceral resection were assessed in patients with clinical locally advanced (cT4) rectal cancer at a national level. DESIGN: This is a population-based study. SETTINGS: Data were retrieved from the Dutch Colorectal Audit. PATIENTS: A total of 2242 of 2881 patients with cT4 rectal cancer between January 2009 and December 2017 were selected. MAIN OUTCOME MEASURES: Main outcomes were resection margins, postoperative complications, and mortality. RESULTS: Multivisceral resection was performed in 936 of 2242 patients, of whom 629 underwent extended multivisceral resection. Positive circumferential margin rate was higher after multivisceral resection than after total mesorectal excision: 21.2% vs 13.9% (p < 0.001). More postoperative complications occurred after limited and extended multivisceral resections than after total mesorectal excision (44.1% and 53.8% vs 37.6%, p < 0.001). Incidence of 30-day mortality was similarly low in both groups (1.5% vs 2.2%, p = 0.20). Independent predictors of postoperative complications were age ≥70 years (OR, 1.28 [95% CI, 1.04–1.56]; p = 0.02), male sex (OR, 1.68 [95% CI, 1.38–2.04]; p< 0.001), mucinous tumors (OR, 1.55 [95% CI, 1.06–2.27]; p = 0.02), extended multivisceral resection (OR, 1.98 [95% CI, 1.56–2.52]; p< 0.001), Hartmann procedure (OR, 1.42 [95% CI, 1.07–1.90]; p = 0.02), and abdominoperineal resection (OR, 1.56 [95% CI, 1.25–1.96]; p < 0.001). LIMITATIONS: Data specifying the extent of multivisceral resections and Clavien Dindo I to II complications were not available. CONCLUSIONS: This population-based study revealed relatively high circumferential margin positivity and postoperative complication rates in patients with cT4 rectal cancer, especially after multivisceral resections, but low mortality rates.

ALTA TASA PERSISTENTE DE MÁRGENES POSITIVOS Y COMPLICACIONES POSTOPERATORIAS DESPUÉS DE LA CIRUGÍA DE CÁNCER RECTAL CT4A NIVEL NACIONAL ANTECEDENTES: A menudo se requiere una resección más extensa en el cáncer de recto localmente avanzado, según la respuesta al tratamiento neoadyuvante preoperatorio. OBJETIVO: Se evaluó la afectación del margen circunferencial y los resultados postoperatorios después de la escisión mesorrectal total y la resección multivisceral en pacientes con cáncer rectal clínico localmente avanzado (cT4) a nivel nacional. DISEÑO: Este es un estudio poblacional. ENTORNO CLINICO: Los datos se recuperaron de la Auditoría colorrectal holandesa. PACIENTES: Se seleccionaron un total de 2242 de 2881 pacientes con cáncer de recto cT4 entre enero de 2009 y diciembre de 2017. PRINCIPALES MEDIDAS DE VALORACION: Los principales resultados fueron los márgenes de resección, las complicaciones postoperatorias y la mortalidad. RESULTADOS: Se realizó resección multivisceral en 936 de 2242 pacientes, de los cuales 629 fueron sometidos a resección multivisceral extendida. La tasa de margen circunferencial positivo fue mayor después de la resección multivisceral que después de la escisión mesorrectal total: 21,2% versus a 13,9% (p <0,001). Se produjeron más complicaciones postoperatorias después de resecciones multiviscerales limitadas y extendidas en comparación con la escisión mesorrectal total (44,1% y 53,8% versus a 37,6%, p <0,001). La incidencia de mortalidad a 30 días fue igualmente baja en ambos grupos (1,5% versus a 2,2%, p = 0,20). Los predictores independientes de complicaciones posoperatorias fueron la edad ≥70 años (OR = 1,28, IC del 95% [1,04 a 1,56], p = 0,02), hombres (OR = 1,68, IC del 95% [1,38 a 2,04], p <0,001), tumores mucinosos (OR = 1,55, IC del 95% [1,06 a 2,27], p = 0,02), resección multivisceral extendida (OR = 1,98, IC del 95% [1,56 a 2,52], p <0,001), Hartmann (OR = 1,42, 95% Cl [1,07 a 1,90], p = 0,02) y resección abdominoperineal (OR 1,56, Cl 95% [1,25 a 1,96], p <0,001). LIMITACIONES: No se disponía de datos que especificaran el alcance de las resecciones multiviscerales y las complicaciones de Clavien Dindo I-II. CONCLUSIONES: Este estudio poblacional reveló tasas de complicaciones postoperatorias y positividad del margen circunferencial relativamente altas en pacientes con cáncer de recto cT4, especialmente después de resecciones multiviscerales, pero tasas de mortalidad bajas.

ObjectivesTo examine general practitioners’ (GP) management of cholecystolithiasis and to evaluate persisting abdominal complaints in the years after the diagnosis.DesignRetrospective analysis of registry data and a subset of individual medical records.SettingSeventeen primary care practices affiliated with the Radboudumc Practice Based Research Network in the Netherlands.Participants633 patients with cholecystolithiasis diagnosed between 2012 and 2016.Primary and secondary outcome measuresThe primary outcome of this study was the healthcare utilisation of patients with cholecystolithiasis diagnosed by the GP in terms of referrals to secondary care, laboratory diagnostics, prescribed medication and the prevalence of concomitant abdominal-related diagnoses in a time interval of 3 years before and 3 years after diagnosis of cholecystolithiasis. For secondary outcomes, electronic medical records were studied from seven practices to assess emergency department visits, operation rates and repeat visits for persistent abdominal symptoms. We compared the non-referred group with the referred group.ResultsIn 57% of patients, concomitant abdominal-related diagnoses were recorded besides the diagnosis cholecystolithiasis. In-depth analyses of 294 patients showed a referral rate of 79.3% (n=233); 62.9% (n=185) underwent cholecystectomy. After referral, 55.4% (129/233) returned to the GP for persistent abdominal symptoms. Patients returning after referral were more often treated for another abdominal-related diagnosis before cholecystolithiasis was recorded (51.9% vs 28.8%, p<0.001).ConclusionsThe majority of patients in general practice with gallstones are referred and undergo cholecystectomy. Patients with concomitant abdominal-related diagnoses are likely to return to their physician. GPs should inform patients about these outcomes to improve the shared decision-making process before gallbladder surgery.

Multimodal prehabilitation programs to improve physical fitness before surgery often include nutritional interventions. This study evaluates the efficacy of and adherence to a nutritional intervention among colorectal and esophageal cancer patients undergoing the multimodal Fit4Surgery prehabilitation program. The intervention aims to achieve an intake of ≥1.5 g of protein/kg body weight (BW) per day through dietary advice and daily nutritional supplementation (30 g whey protein). This study shows 56.3% of patients met this goal after prehabilitation. Mean daily protein intake significantly increased from 1.20 ± 0.39 g/kg BW at baseline to 1.61 ± 0.41 g/kg BW after prehabilitation (p < 0.001), with the main increase during the evening snack. BW, BMI, 5-CST, and protein intake at baseline were associated with adherence to the nutritional intervention. These outcomes suggest that dietary counseling and protein supplementation can significantly improve protein intake in different patient groups undergoing a multimodal prehabilitation program.
