RESUMO

A 61-year-old woman developed neorectal prolapse after laparoscopic low anterior resection, total mesorectal excision with partial intersphincteric resection and handsewn coloanal anastomosis for rectal cancer. She presented with a 3 cm full thickness reducible prolapse, with associated anal pain and bleeding. A perineal stapled prolapse resection was performed to address the rectal prolapse, with satisfactory results.

RESUMO

BACKGROUND/AIM: This study aimed to determine the effectiveness of surgical site infection (SSI) prevention approaches in rectal cancer surgery. PATIENTS AND METHODS: A total of 1,408 patients who underwent elective rectal cancer surgery between 1995 and 2017 were reviewed. Patients were divided into three groups: control group (group A, n=245), SSI prevention intervention group (group B, n=516), and laparoscopic or robotic surgery group (group C, n=647). The groups were compared in terms of SSI and anastomotic leakage (AL) incidences, and risk factors for SSI were investigated. RESULTS: The overall SSI and AL rates were 19.4% and 3.6%, respectively. These rates were significantly lower in Group C (9.3%, 1.7%), compared to Groups A (40.0%, 6.1%) and B (22.5%, 3.5%). Abdominoperineal resection, open surgery, operation time, intraoperative bleeding, lack of absorbable sutures, lack of mechanical bowel preparation, and lack of oral antibiotics were independently associated with SSI. CONCLUSION: SSI reduction after rectal cancer surgery was achieved through various intervention strategies.

RESUMO

BACKGROUND: To explore the correlation between preoperative serum albumin-globulin ratio (AGR) and the prognosis of patients undergoing low rectal cancer surgery. METHODS: A total of 152 patients treated from June 2013 to June 2015 were selected. They were divided into survival group (n = 128) and death group (n = 24). Their general clinical data and preoperative and postoperative serum albumin (ALB), globulin (GLB) levels, and AGR were compared. Multivariate logistic regression analysis was performed for influencing factors for postoperative death. A nomogram prediction model was established based on independent risk factors. The predictive value of AGR for clinical outcomes was analyzed by receiver operating characteristic (ROC) curve, and the optimal cut-off value was obtained. The correlation between AGR and postoperative clinical outcomes was analyzed. The patients were divided into group A and B according to cut-off value, survival curves were plotted by Kaplan-Meier method, and 5-year survival rates were compared. RESULTS: There were significant differences in tumor stage, cell differentiation, depth of tumor invasion, lymph node metastasis, chemotherapy, preoperative ALB, GLB, and AGR between the two groups, which were all independent risk factors for death. After operation, ALB and AGR significantly declined and were significantly lower in the death group than those in the survival group. The death group had significantly higher GLB level than that of the survival group. The optimal cut-off value of AGR for predicting death was 1.73. AGR was significantly correlated with postoperative clinical outcomes. The survival rate of patients with AGR > 1.73 significantly exceeded that of cases with AGR ≤ 1.73. CONCLUSIONS: The preoperative serum AGR is an independent risk factor for the postoperative clinical outcomes of patients with low rectal cancer and has a high predictive value. Lower AGR indicates higher risk of postoperative death.

RESUMO

We observed a case of long-term survival without recurrence following hepatectomy and lung resection in a patient with hepatopulmonary metastases, which appeared 7 months after rectal cancer surgery. We report the case of a 68-year-old man whose chief complaint was anal pain. The patient was referred to our hospital because of a suspected rectal cancer. He was diagnosed with rectal cancer without distant metastasis, and abdominoperineal excision was then performed. Histopathological findings revealed Rb, type 2, 85×60 mm, tub 2, ly1, v1, pPM0, pDM0, pRM0, pT3(A), pN0(0/27), cM0, and pStage Ⅱa. Seven months after the surgery, abdominal computed tomography(CT)revealed a 3 cm nodule in segment 7 of the liver. In addition, chest CT detected a 2 mm nodule in segment 3 of the upper lobe of the left lung. Hepatectomy was immediately performed, whereas lung nodules were to be followed up. Three months later, chest CT showed that the lung nodules had increased in size(approximately 5 mm); therefore, the patient was diagnosed with lung metastasis, and thoracoscopic partial lung resection was performed. The histopathological findings of the hepatic tumor and lung tumor were similar to those of rectal cancer. The postoperative course was good, and the patient has been alive without recurrence for 8 years since the final surgery(lung resection)without postoperative adjuvant chemotherapy.

RESUMO

PURPOSE: Pathological extramural venous invasion (EMVI) is defined as the active invasion of malignant cells into veins beyond the muscularis propria in colorectal cancer. It is associated with poor prognosis and increases the risk of disease recurrence. Specific findings on MRI (termed MRI-EMVI) are reportedly associated with pathological EMVI. In this study, we aimed to identify risk factors for lateral lymph node (LLN) metastasis related to rectal cancer and to evaluate whether MRI-EMVI could be a new and useful imaging biomarker to help LLN metastasis diagnosis besides LLN size. METHODS: We investigated 67 patients who underwent rectal resection and LLN dissection for rectal cancer. We evaluated MRI-EMVI grading score and examined the relationship between MRI-EMVI and LLN metastasis. RESULTS: Pathological LLN metastasis was detected in 18 cases (26.9%), and MRI-EMVI was observed in 32 cases (47.8%). Patients were divided into two cohorts, according to LLN metastasis. Multivariate analyses demonstrated that higher risk of LLN metastasis was significantly associated with MRI-EMVI (P = 0.0112) and a short lateral lymph node axis (≥ 5 mm) (P = 0.0002). The positive likelihood ratios of MRI-EMVI alone, LLN size alone, and the combination of both factors were 2.12, 4.84, and 16.33, respectively. Patients negative for both showed better 2-year relapse-free survival compared to other patients (84.4% vs. 62.1%, P = 0.0374). CONCLUSIONS: MRI-EMVI was a useful imaging biomarker for identifying LLN metastasis in patients with rectal cancer. The combination of MRI-EMVI and LLN size can improve diagnostic accuracy.

RESUMO

AIM: Anastomotic leakage represents the most fearful complication in colorectal surgery. Important risk factors for leakage are low anastomoses and preoperative radiotherapy. Many surgeons often unnecessarily perform a protective ileostomy, increasing costs and necessitating a second operation for recanalization. The aim of this study was to evaluate the role of indocyanine green in assessing bowel perfusion, even in cases of a low anastomosis on tissue treated with radiotherapy. PATIENTS AND METHODS: Two groups of patients were selected: Group A (risky group) with only low extraperitoneal rectal tumors (<8 cm) previously treated with neoadjuvant chemo-radiotherapy; group B (no risk group) with only intraperitoneal rectal tumors (>8 cm), not previously treated with neoadjuvant therapy. Clinical postoperative outcome, morbidity, mortality and anastomotic leakage were compared between these two groups. RESULTS: In group A, comprised of 35 patients, the overall complication rate was 8.6%, with two patients developing anastomotic leakage (5.7%). In group B, comprised of 53 patients, the overall complication rate was 17% with four cases with anastomotic leakage (7.5%). No statistical difference was observed for conversion rate, general complications, or anastomotic leakage. No statistical differences were observed in clinical variables except for American Society of Anesthesiologist score (p=0.04). Patients who developed complications during radiotherapy had no significant differences in postoperative outcomes compared with other patients. CONCLUSION: Indocyanine green appears to be safe and effective in assessing the perfusion of colorectal anastomoses, even in the highest-risk cases, potentially reducing the rate of ileostomy. The main limitation remains the lack of a universally replicable standard assessment.

RESUMO

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.

RESULTADOS FUNCIONALES Y CALIDAD DE VIDA DE LOS PACIENTES DESPUS DE LA ESCISIN MESORRECTAL TOTAL TRANSANAL PARA CNCER DE RECTO UN ESTUDIO PROSPECTIVO OBSERVACIONAL: ANTECEDENTES:Pocos estudios han abordado el impacto funcional después de la escisión mesorrectal total transanal.OBJETIVO:Evaluar la función y la calidad de vida relacionada con la salud en pacientes con cáncer de recto tratados con escisión mesorrectal total transanal.DISEÑO:Se seleccionaron pacientes consecutivos tratados entre 2016 y 2018. Se estudió su función y calidad de vida, en la etapa preoperatoria, a los tres y doce meses postoperatorios.METODO:Serie de casos prospectivos.PACIENTES:Los pacientes eran incluidos en presencia de anastomosis primaria, cierre del estoma de derivación y en ausencia de fuga anastomótica. Finalmente se incluyeron cuarenta y cinco pacientes. Un total de 31 (68,8%) y 32 pacientes (71,1%) completaron las encuestas de tres y doce meses, respectivamente.INTERVENCIONES:Escisión mesorrectal total transanal estándar.PRINCIPALES MEDIDAS DE RESULTADO:Los criterio de evaluación principal fueron los resultados funcionales y de calidad de vida mediante cuestionarios previamente validados. Los criterios de evaluación secundarios incluyeron los valores obtenidos con ecografía endoanal, manometría anorrectal y prueba de sensibilidad rectal.RESULTADOS:La escala de Wexner y el síndrome de resección anterior baja aumentaron significativamente tres meses después de la cirugía, pero volvieron a los valores iniciales a los doce meses. La tasa de "síndrome de resección anterior inferior grave" al final del seguimiento fue del 25,0% (+ 11,7% en comparación con el valor inicial, p = 0,314). La función sexual y urinaria se mantuvo estable durante todo el estudio, aunque se detectó una mejora clínica significativa en la libido masculina. Entre los criterios que evalúan la calidad de vida, todas las alteraciones en la misma volvieron a los valores iniciales, doce meses después de la cirugía, excepto el aumento de flatulencia, la mejoría del insomnio y el estreñimiento. A los doce meses, se encontró una disminución esperada en el grosor medio del esfínter interno, la presión anal en reposo y el volumen umbral para la presencia de tenesmo.LIMITACIONES:Tamaño de muestra limitado, ausencia de un grupo comparativo, falta significativa de datos para identificar la dificultad para la actividad sexual femenina y el efectuar ecografía y manometría a los tres meses.CONCLUSIONES:Los pacientes sometidos a escisión mesorrectal total transanal refieren una calidad de vida y resultados funcionales aceptables a los doce meses después de la cirugía.

RESUMO

BACKGROUND: A permanent stoma is an unintended consequence that cannot be avoided completely after intersphincteric resection for ultralow rectal cancer. Unfortunately, its incidence and risk factors have been poorly defined. OBJECTIVE: The objective was to determine the cumulative incidence and risk factors of permanent stoma after intersphincteric resection for ultralow rectal cancer. DESIGN: This study was a retrospective analysis of prospectively collected data. SETTINGS: This study was conducted at a colorectal surgery referral center. PATIENTS: A total of 185 consecutive patients who underwent intersphincteric resection with diverting ileostomy from 2011 to 2019 were included. MAIN OUTCOME MEASURES: The primary outcome was the incidence of and risk factors for the permanent stoma. The secondary outcome included differences in stoma formation between patients with partial, subtotal, and total intersphincteric resection. RESULTS: After a median follow-up of 40 months (range, 6-107 months), 26 of 185 patients eventually required a permanent stoma, accounting for a 5-year cumulative incidence of 17.4%. The causes of permanent stoma were anastomotic morbidity (46.2%, 12/26), local recurrence (19.2%, 5/26), distant metastasis (19.2%, 5/26), fecal incontinence (3.8%, 1/26), perioperative mortality (3.8%, 1/26), patients' refusal (3.8%, 1/26), and poor general condition (3.8%, 1/26). Although the incidence of permanent stoma was significantly different between the intersphincteric resection groups (partial vs subtotal vs total: 8.3% vs 20% vs 25.8%, p = 0.02), it was not an independent predictor of stoma formation. Multivariate analysis demonstrated that anastomotic leakage (OR = 5.29; p = 0.001) and anastomotic stricture (OR = 5.13; p = 0.002) were independently predictive of permanent stoma. LIMITATIONS: This study was limited by its retrospective nature and single-center data. CONCLUSIONS: The 5-year cumulative incidence of permanent stoma was 17.4%. Anastomotic complications were identified as risk factors. Patients should be informed of the risks and benefits when contemplating the ultimate sphincter-sparing surgery. It might be preferable to decrease the probability of permanent stoma by further minimizing anastomotic complications. See Video Abstract at http://links.lww.com/DCR/B704. INCIDENCIA ACUMULADA Y FACTORES DE RIESGO DE ESTOMA PERMANENTE DESPUS DE UNA RESECCIN INTERESFNTRICA EN CNCER RECTAL ULTRA BAJO: ANTECEDENTES:La necesidad de efectuar un estoma permanente es la consecuencia no intencional e inevitable por completo después de una resección interesfintérica en presencia de un cáncer rectal ultra bajo. Desafortunadamente, la incidencia y los factores de riesgo se han definido en una forma limitada.OBJETIVO:El objetivo fue determinar la incidencia acumulada y los factores de riesgo para la necesidad de efectuar un estoma permanente después de la resección intersfintérica de un cáncer rectal ultra bajo.DISEÑO:El presente estudio es un análisis retrospectivo de la información obtenida.ESCENARIO:Centro de referencia de cirugía colo-rectal.PACIENTES:Se incluyeron un total de 185 pacientes consecutivos que se sometieron a resección intersfintérica de un cáncer rectal ultra bajo con ileostomía de derivación de 2011 a 2019.MEDICION DE RESULTADOS:El resultado principal fue la identificación de la incidencia y los factores de riesgo para la presencia de un estoma permanente. En forma secundaria se describieron los resultados de las diferentes técnicas de la formación de un estoma entre los pacientes con resección interesfintérica parcial, subtotal o total.RESULTADOS:Posterior a una media de seguimiento de cuarenta meses (rango de 6 a 107), 26 de 185 pacientes requirieron en forma eventual un estoma permanente, lo que equivale a una incidencia acumulada a cinco años de 17.4 %. Las causas para dejar un estoma permanente fueron morbilidad de la anastomosis (46.2%, 12/26), recurrencia local (19.2%, 5/26), metástasis a distancia (19.2%, 5/26), incontinencia fecal (3.8%, 1/26), mortalidad perioperatoria (3.8%, 1/26), rechazo del paciente (3.8%, 1/26), y malas condiciones generales (3.8%, 1/26). Aunque la incidencia de un estoma permanente fue significativamente diferente entre los grupos de resección interesfintérica (parcial vs subtotal vs total: 8.3% vs 20% vs 25.8%, p = 0.02), no se consideró un factor predictor independiente para la formación de estoma. En el análisis multivariado se demostró que la fuga anatomótica (OR = 5.29; p = 0.001) y la estenosis anastomótica (OR = 5.13; p = 0.002) fueron factores independientes para predecir la necesidad de un estoma permanente.LIMITACIONES:La naturaleza retrospectiva del estudio y la información proveniente de un solo centro.CONCLUSIONES:La incidencia acumulada a cinco años de estoma permantente fue de 17.4%. Se consideran a las complicaciones anastomóticas como factores de riesgo. Los pacientes deberán ser informados de los riesgos y beneficios cuando se considere la posibilidad de efectuar una cirugía preservadora de esfínteres finalmente. Puede ser preferible disminuir la probabilidad de dejar un estoma permanente tratando de minimizar la posibilidad de complicaciones de la anastomosis.

RESUMO

BACKGROUND: There is limited evidence on the efficacy of acupuncture in bowel dysfunction treatment. OBJECTIVE: The aim of this pilot study was to investigate the potential value of acupuncture in the treatment of low anterior resection syndrome. DESIGN: This was an open-design pilot study. SETTINGS: This was a single-center study. PATIENTS: Nine (5 female) patients with major low anterior resection syndrome were included. INTERVENTIONS: All patients underwent acupuncture by a trained specialist once a week for 10 weeks. MAIN OUTCOME MEASURES: Bowel function was assessed by using the low anterior resection syndrome score and the Memorial Sloan-Kettering Cancer Center bowel function instrument before the procedure, just after finishing the course of acupuncture, and 6 months after the treatment. RESULTS: The average age was 56.44 (50-65; SD ±5.4). Median age was 56 years. At the end of the procedure, all patients reported significant improvement in low anterior resection syndrome symptoms: the average low anterior resection syndrome score before acupuncture was 39 (±2.7), after acupuncture it was 30.3 (±10.6), and 6 months after acupuncture it was 7.22 (±10.244; p < 0.000). The average Memorial Sloan-Kettering Cancer Center bowel function instrument score before acupuncture was 55.33 (±11.55), after the procedure it was 60 (±14.97), and 6 months later it was 70.22 (±12.2; p < 0.000). LIMITATIONS: The small sample size and the fact that this is a single-center nonblinded study are limitations of this work. CONCLUSIONS: Acupuncture may be effective in low anterior resection syndrome treatment and needs further evaluation. The procedure is safe and feasible.

RESUMO

BACKGROUND/AIM: Impact of neoadjuvant chemoradiotherapy (CRT) in locally advanced upper rectal adenocarcinoma (LAURC) is debated. The aim of this study was to compare outcomes between LAURC and locally advanced sigmoid and recto-sigmoid junction cancer (LASC). PATIENTS AND METHODS: This retrospective study included 149 consecutive patients [42 CRT/LAURC, 16 upfront surgery (US/LAURC) and 91 LASC]. Partial mesorectum excision (PME) was performed for all LAURC. Pathology results as well as short-and-long-term outcomes were compared between the three groups. RESULTS: Overall mortality was nil. Morbidity was comparable (CRT/LAURC 23.8% vs. LASC: 20.8% vs. US/LAURC: 37.5%, p=0.2354). CRT was associated with a reduced risk of positive circumferential margin (CRT/LAURC: 9.5% vs. US/LAURC: 18.7%, p<0.0001). Recurrence rate, 5-year disease-free survival and overall survival were similar between the three groups. CONCLUSION: CRT and PME did not improve LAURC oncological outcomes but were associated with improved margins. CRT for LAURC was not associated with increased morbidity.

RESUMO

A 72-year-old man had a chief complaint of anal pain and difficulty in defecation. He was diagnosed with adenocarcinoma by biopsy from a tumor of the anal canal. A computed tomography scan revealed neither regional lymph node metastasis nor distant metastasis. Hence, he was diagnosed with cT3N0M0, cStage Ⅱa anal canal cancer. Preoperative capecitabine- based chemoradiotherapy(CRT)(50.4 Gy in 28 fractions of 1.8 Gy each)was implemented. Digital rectal examination and imaging evaluation 8 weeks after preoperative CRT revealed that the tumor had shrunk. Fifteen weeks after preoperative CRT, laparoscopic abdominoperineal resection was performed. The pathological findings showed mucinous adenocarcinoma associated with anal fistula. At present, 12 months after the operation, no local recurrence and distant metastasis has been detected under follow-up evaluations.

RESUMO

AIM: We aimed to compare the outcomes of different therapeutic modalities in rectal carcinoid tumors. METHOD: We retrospectively collected 145 patients with rectal carcinoid tumors which were pathologically diagnosed from 2005/01/01 to 2016/12/31. We compared tumor size, complete resection rate and recurrent rate between different therapeutic modalities. Then, prospectively compared the treatment outcomes of 28 patients treated with ligation assisted endoscopic mucosal resection (LEMR) and 25 patients treated with endoscopic mucosal resection with cap (EMRC). RESULT: The mean size of tumors was 6.5 mm (1-25 mm), and the mean follow-up duration was 26 months (6-118 months). The therapeutic modalities included ligation-assisted endoscopic mucosal resection (LEMR) (25 tumors, 17%), endoscopic mucosal resection (EMR) (31 tumors, 21%), snare polypectomy (30 tumors, 21%), biopsy forceps removal (46 tumors, 32%) and surgical resection (13 tumors, 11%), including 6 tumors treated with transanal endoscopic microsurgery (TEM) method. In view of pathologically complete resection rate, LEMR was highest (100%), followed by surgical resection (85%). However, EMR only had 42% pathologically complete resection rate. Besides, LEMR and surgical resection had no local recurrence and significantly higher clinically complete resection rate, compared to other treatments. For the further prospective study, complete resection was noted in 28 (100%) patients in LEMR group and 13 (52%) patients in EMRC group. CONCLUSION: In the treatment of rectal carcinoid tumors, LEMR is safe and effective compared with traditional endoscopic treatments.

RESUMO

Objective: To determine the effect of peritoneum reconstruction on postoperative complications after laparoscopic low anterior resection (LAR) for rectal cancer. Methods: Retrospective cohort study and propensity score matching were conducted. Case inclusion criteria: (1) pathologically confirmed rectal adenocarcinoma; (2) 18 to 80 years; (3) patients with middle to low rectal cancer undergoing laparoscopic LAR; (4) patients staging cT1-4aN0-2M0 or ycT1-4aN0-2M0 after neoadjuvant therapy; (5) the distance of 4-10 cm from tumor low margin to anal verge. Exclusion criteria: (1) abdominal surgery history (except appendicitis, cholecystitis, ectopic pregnancy); (2) anastomosis above the peritoneal reflection; (3) tumor distant metastasis or clinical staging of T4b during surgery; (4) conversion to open surgery; (5) severe incapacitating disease (American Society of Anesthesiologists classification IV or V, ASA). A total of 666 patients with middle to low rectal cancer undergoing laparoscopic LAR in The First Affiliated Hospital of Army Medical University from January 2017 to June 2020 were enrolled. There were 473 males and 193 females with the median age of 59 (18-80) years. Laparoscopic LAR with peritoneum reconstruction was performed in 188 cases (PR group), and laparoscopic LAR without peritoneum reconstruction was performed in 478 cases (NPR group). After 1:1 propensity score matching according to 1:1 based on age, gender, body mass index, TNM staging, ASA classification, intraoperative blood loss, distance from tumor low margin to anal edge, 153 cases were included in each group. Postoperative complications were classified according to Clavien-Dindo classification. Anastomotic leakage was defined and graded according to the International Study Group of Rectal Cancer (ISGRC) criteria. Results: After propensity score matching, there were no significant differences in baseline demographic characteristics between the 2 groups (all P>0.05), indicating that these two groups were comparable. (1) Operative conditions: All the patients in both groups completed operation successfully. Compared with the NPR group, the PR group had longer operation time [(181.3±60.3) minutes vs. (168.9±51.5) minutes, t=2.185, P=0.029], shorter postoperative median hospital stay [8 (7, 10) days vs. 9 (7, 11) days, Z=-2.282, P=0.022], and the differences were statistically significant (P<0.05). (2) Postoperative complications: The overall morbidity of postoperative complication in PR group and NPR group was 20.3% (31/153) and 24.2% (37/153) respectively, and the incidence of anastomotic leakage was 9.8% (15/153) and 11.1%(17/153) respectively, whose differences were not statistically significant (both P>0.05). Compared with NPR group, PR group had lower morbidity of grade III to IV complications [3.9% (6/153) vs. 11.1% (17/153), χ(2)=5.688, P=0.017] and lower secondary operation rate [1.3% (2/153) vs. 5.9% (9/153), χ(2)=4.621, P=0.032], the differences were statistically significant (both P<0.05). Though PR group had lower incidence of grade C anastomoic leakage [1.3% (2/153) vs. 3.9% (6/153), χ(2)=2.054, P=0.152], but the differences were not statistically significant. (3) Postoperative inflammation: The difference of the procalcitonin level of both PR and NPR groups at postoperative 1-d, 3-d, and 5-d was statistically significant (F=5.222, P=0.010) in time-dependent manner, while the difference was not significant in the interaction effect (P>0.05). No statistically significant differences in the C-reactive protein level between two groups at postoperative 1-d, 3-d, and 5-d were found (all P>0.05). Conclusion: Peritoneum reconstruction in laparoscopic LAR can decrease the morbidity of postoperative complication of grade III to IV and the reoperation rate, and plays an important role in controlling the inflammatory reaction, which has great clinical value.

RESUMO

AIM: It is still controversial whether the addition of lateral pelvic lymph node (LPN) dissection (LPND) to total mesorectal excision (TME) can provide a survival benefit after neoadjuvant chemoradiotherapy (nCRT) in rectal cancer patients with pathological lateral lymph node metastasis (LPNM). METHODS: Patients with clinically suspected LPNM who underwent nCRT followed by TME + LPND were systematically reviewed and divided into the positive LPN group (n = 15) and the negative LPN group (n = 58). Baseline characteristics, clinicopathological data and survival outcomes were collected and analysed. RESULTS: Of the 73 patients undergoing TME + LPND after nCRT, the pathological LPNM rate was 20.5% (15/73). Multivariate analysis showed that a post-nCRT LPN short diameter ≥ 7 mm (OR 49.65; 95% CI 3.98-619.1; P = 0.002) and lymphatic invasion (OR 9.23; 95% CI 1.28-66.35; P = 0.027) were independent risk factors for pathological LPNM. The overall recurrence rate of patients with LPNM was significantly higher than that of patients without LPNM (60.0% vs 27.6%, P = 0.018). Multivariate regression analysis identified that LPNM was an independent risk factor not only for overall survival (OS) (HR 3.82; 95% CI 1.19-12.25; P = 0.024) but also for disease-free survival (DFS) (HR 2.33; 95% CI 1.02-5.14; P = 0.044). Moreover, N1-N2 stage was another independent risk factor for OS (HR 7.41; 95% CI 1.63-33.75; P = 0.010). CONCLUSIONS: Post-nCRT LPN short diameter ≥ 7 mm and lymphatic invasion were risk factors for pathological LPNM after nCRT. Furthermore, patients with pathological LPNM still show an elevated overall recurrence rate and poor prognosis after TME + LPND. Strict patient selection and intensive perioperative chemotherapy are crucial factors to ensure the efficacy of LPND.

RESUMO

OBJECTIVE: Anastomotic leakage (AL) is the most serious postoperative complication following anterior resection for rectal cancer. We aimed to investigate the efficacy of active drainage for the management of AL. METHODS: This was a retrospective study using information from a database of patients who underwent colorectal resection without a defunctioning ileostomy at our center between September 2013 and January 2021. We identified 122 cases with definitive AL who did not require revision emergent laparotomy. Among these patients, we evaluated those who received active drainage to replace the original passive drainage. RESULTS: There were 62 cases in the active drainage group and 60 cases in the passive drainage group. The active drainage group had a shorter mean AL spontaneous resolution time (26.9 ± 3.3 vs. 32.2 ± 4.8 days) and lower average hospitalization costs (82,680.6 vs. 92,299.3 renminbi (RMB)) compared with the passive drainage group, respectively. Moreover, seven patients in the passive drainage group subsequently underwent diverting stoma to resolve the Al, while all ALs resolved spontaneously after replacing the passive drainage with active drainage. CONCLUSIONS: Our study suggests that active drainage may accelerate the spontaneous resolution of AL.

RESUMO

BACKGROUND: Postoperative chylous ascites is an infrequent condition after colorectal surgery and is easily treatable. However, its effect on the long-term oncological prognosis is not well established. This study aimed to investigate the short-term and long-term impact of chylous ascites treated with neoadjuvant therapy followed by rectal cancer surgery and to evaluate the incidence of chylous ascites after different surgical approaches. METHODS: A total of 898 locally advanced rectal cancer patients treated with neoadjuvant chemoradiotherapy followed by surgery between January 2010 and December 2018 were included. The clinicopathological data and outcomes of the patients with chylous ascites were compared with those of the patients without chylous ascites. The primary endpoint was recurrence-free survival (RFS). To balance baseline confounders between groups, propensity score matching (PSM) was performed for each patient with a logistic regression model. RESULTS: Chylous ascites was detected in 3.8% (34/898) of the patients. The incidence of chylous ascites was highest after robotic surgery (6.9%, 6/86), followed by laparoscopic surgery (4.2%, 26/618) and open surgery (1.0%, 2/192, P = 0.021). The patients with chylous ascites had a significantly higher number of lymph nodes harvested (15.6 vs. 12.8, P = 0.009) and a 3-day longer postoperative hospital stay (P = 0.017). The 5-year RFS rate was 64.5% in the chylous ascites group, which was significantly lower than the rate in the no chylous ascites group (79.9%; P = 0.007). The results remained unchanged after PSM was performed. The chylous ascites group showed a nonsignificant trend towards a higher peritoneal metastasis risk (5.9% vs. 1.6%, P = 0.120). Univariate analysis and multivariate analysis confirmed chylous ascites (hazard ratio= 3.038, P < 0.001) as an independent negative prognostic factor for RFS. CONCLUSIONS: Considering the higher incidence of chylous ascites after laparoscopic and robotic surgery and its adverse prognosis, we recommend sufficient coagulation of the lymphatic tissue near the vessel origins, especially during minimally invasive surgery.

RESUMO

BACKGROUND: Anastomotic leak is a serious complication of rectal cancer surgery that leads to increased morbidity and mortality. Its incidence is 3-21%, usually appearing 5-7 days after surgery, although there are cases of late presentation as chronic anastomotic fistulas or sinuses. CASE REPORT: We present three cases of patients who underwent anterior resection for rectal cancer and developed necrotizing fasciitis due to late anastomotic leaks. CONCLUSIONS: We believe that early and resolutive surgical treatment is recommended for chronic anastomotic fistulas or sinuses, even when asymptomatic, because of the associated risk of necrotizing fasciitis.


ANTECEDENTES: La dehiscencia anastomótica es una complicación grave de la cirugía del cáncer de recto que conlleva un aumento de la morbimortalidad. Su incidencia se sitúa en un 3-21%, manifestándose habitualmente alrededor del quinto a séptimo días de posoperatorio, si bien existen casos de presentación tardía en forma de fístulas o sinus anastomóticos crónicos. CASOS CLÍNICOS: Presentamos tres casos de pacientes intervenidos mediante resección anterior por cáncer de recto que desarrollaron fascitis necrotizante secundaria a dehiscencia anastomótica tardía. CONCLUSIONES: Creemos recomendable el tratamiento quirúrgico resolutivo y precoz de las fístulas y sinus anastomóticos crónicos, incluso asintomáticos, por el potencial riesgo de fascitis necrotizante que suponen.

RESUMO

OBJECTIVES: The present study compares abdominoperineal resection (APR) performed by minimally invasive and open approach, regarding preoperative selection criteria, intraoperative and early postoperative aspects, in choosing the suitable technique performed by surgical teams with experience in both open and minimally invasive surgery (MIS). Methods: This is a retrospective study, conducted between 2008-2020. Two hundred thirty-three patients with APR performed for low rectal or anal cancer were included. The cohort was divided into two groups, depending on the surgical approach used: Minimally Invasive Surgery (laparoscopic and robotic procedures) and Open Surgery (OS). The perioperative characteristics were analyzed in order to identify the optimal approach and a possible selection criteria. Results: We identified a high percentage of patients with a history of abdominal surgery in the open group (p = .0002). Intraoperative blood loss was significantly higher in the open group (p= .02), with an increased number of simultaneous resections (p = .041). The early postoperative outcome was marked by significantly lower morbidity in the MIS group (p = .005), with mortality recorded only in the open group (3 cases), in patients that associated severe comorbidities. The hystopathological results identified a significant number of patients with stage T2 in the MIS group (p= .037). Conclusions: Minimally invasive surgery provides a major advantage to APR, by avoiding an additional incision, the specimen being extracted through the perineal wound. The success of MIS APR seems to be assured by a good preoperative selection of the patients, alongside with experienced surgical teams in both open and minimally invasive rectal resections. The lack of conversion identified in robotic APR confirm the technical superiority over laparoscopic approach.
