ABSTRACT

Abstract Background Colorectal resection anastomosis is the commonest cause of rectal strictures. Anastomotic site ischemia, incomplete doughnuts from stapled anastomosis and pelvic infection, are some of the risk factors that play a role in the development of postoperative rectal strictures. However, the role of diverting stoma in the development of rectal strictures has not been studied extensively. Objectives To study the difference in the occurrence of anastomotic strictures (AS) in patients submitted to low anterior resection (LAR) with covering ileostomy (CI), and to LAR without CI for carcinoma rectum. Methods This was a prospective, comparative case control study carried out at a tertiary care referral center. Low anterior resection with covering ileostomy was performed in patients with rectum carcinoma in the study group, while LAR without covering ileostomy was performed in the control group. The study group had 29 patients, while the control group had 33 patients with rectum carcinoma. Results During themean follow-up period of 9.1months, 8 (28%) patients in the study group and 2 (6%) patients in the control group developed AS (p =0.019). Out of these 8 patients with AS in the study group, 50% had Grade-I AS, 25% had Grade-II AS, while 25% of the patients had Grade-III (severe) AS. However, both patients who developed AS in the control group had a mild type (Grade I) of AS. Conclusion Covering ileostomy increases the chances of AS formation after LAR for rectum carcinoma. Also, the SKIMS Clinical Grading of Rectal Strictures is a simple and


Resumo Introdução A anastomose de ressecção colorretal é a causa mais comum de estenoses retais. A isquemia do local da anastomose, donuts (anéis) incompletos de anastomose grampeada e infecção pélvica são alguns dos fatores de risco que desempenham um papel no desenvolvimento de estenoses retais pós-operatórias. No entanto, o papel do estoma de desvio no desenvolvimento de estenoses retais não foi estudado extensivamente. Objetivos Estudar a diferença na ocorrência de estenoses anastomóticas (EA) em pacientes submetidos à ressecção anterior baixa (LAR) com ileostomia de proteção e a LAR sem ileostomia de proteção para carcinoma de reto. Métodos Este foi um estudo prospectivo e comparativo de caso-controle realizado em um centro de referência de atenção terciária. A ressecção anterior baixa com ileostomia de proteção foi realizada em pacientes com carcinoma de reto no grupo de estudo, enquanto LAR sem ileostomia de proteção foi realizada no grupo controle. O grupo de estudo tinha 29 pacientes, enquanto o grupo controle tinha 33 pacientes com carcinoma de reto. Resultados Durante o período de acompanhamento médio de 9, 1 meses, 8 (28%) pacientes no grupo de estudo e 2 (6%) pacientes no grupo controle desenvolveram EA (p=0,019). Destes 8 pacientes com EA no grupo de estudo, 50% tinham EA de Grau I, 25% tinhamEA de Grau II, enquanto 25% dos pacientes tinham EA de Grau III (grave). No entanto, ambos os pacientes que desenvolveram EA no grupo de controle tinham um tipo leve (Grau I) de EA. Conclusão A ileostomia de proteção aumenta as chances de formação de AS após LAR para carcinoma de reto. Além disso, o SKIMS Clinical Grading of Rectal Strictures é uma ferramenta simples e útil disponível para cada cirurgião para graduar, classificar e monitorar as estenoses retais pós-operatórias.

ABSTRACT

The preservation of left colonic artery (LCA) has been accepted by more and more surgeons in the radical resection of rectal cancer, but whether it can reduce anastomotic complications and affect the oncology efficacy remains controversial. This consensus elaborates the significance, anatomical structure, key points of operation techniques, indications and contraindications, and surgical approaches of LCA preservation. Each statement and recommendation was recognized by most experts in the field of colorectal surgery. The purpose of this consensus is to improve the cognitive level of Chinese colorectal surgeons on LCA preservation, so as to standardize the surgical strategies and methods of LCA preservation and furthermore practice, and promote it. The pending issues in this consensus need further high-quality clinical studies.

ABSTRACT

ABSTRACT Introduction: Anastomotic leakage is a complication of intestinal anastomosis, with an incidence of 2%-7% in centers of experience. To be able to achieve an early detection, serological markers such as Procalcitonin were included. Methods: Descriptive retrospective cohort study of patients taken to colorectal surgery with intestinal anastomosis, the objective is to estimate association between procalcitonin (≥2 ng/dl) as an early inflammatory marker and anastomotic leakage in a Coloproctological Service of a highest level of health care hospital, between September 2017 and January 2019. Results: Cohort of 237 patients, 51% women (18-89 years), with multiple comorbidities in 81% of patients, colon cancer was the most operated pathology (53.1%). Laparoscopic approach was the most applied 60.34%, colorectal anastomosis was the most frequently performed (47.26%). Ileocolic anastomosis presented a higher frequency (43.75%-n:7) of dehiscence. Anastomotic leakage was associated with a serum procalcitonin positive 3 days postoperatively (p-value <0.05). Patients with a positive result had 4.28 times higher risk of presenting an anastomotic leak, compared to this risk in those patients with negative results 3 days postoperatively, this association was statistically significant 95% CI (1.34-14.16); p value <0.05. Conclusion: Anastomotic leakage is a source of morbidity in patients taken to intestinal anastomosis. It's necessary to guarantee an early diagnosis of this complication, prevent abscesses and secondary peritonitis, providing adequate treatment and even reducing the associated mortality. We recommend including the procalcitonin in the assessment protocol on the third day of postoperative follow-up.


RESUMO Introdução: O vazamento anastomótico é uma complicação da anastomose intestinal, com uma incidência de 2% a 7% em centros com experiência. Para conseguir uma detecção precoce, foram incluídos marcadores sorológicos como a Procalcitonina. Métodos: Estudo de coorte descritivo e retrospectivo de pacientes submetidos à cirurgia colorretal com anastomose intestinal, cujo objetivo é estimar a associação entre os níveis de procalcitonina (≥ 2 ng/dL) como marcador inflamatório precoce e vazamento anastomótico em um Serviço de Coloproctologia de alto nível de atenção à saúde hospitalar, entre setembro de 2017 a janeiro de 2019. Resultados: Coorte de 237 pacientes, 51% mulheres (18−9 anos), com múltiplas comorbidades em 81% dos pacientes, sendo o câncer de cólon a patologia mais operada (53,1%). A abordagem laparoscópica foi a mais utilizada, em 60,34%, e a anastomose colorretal foi a mais frequentemente realizada (47,26%). A anastomose ileocólica apresentou a maior frequência (43,75%, n = 7) de deiscências. O vazamento anastomótico foi associado a procalcitonina sérica positiva 3 dias após a cirurgia (p < 0,05). Pacientes com resultado positivo tinham um risco 4,28 vezes maior de apresentar vazamento anastomótico, em comparação com esse mesmo risco nos pacientes com resultado negativo 3 dias após a cirurgia, sendo essa associação estatisticamente significativa, (IC95%:1,34−14,16); p < 0,05. Conclusão: O vazamento anastomótico é fonte de morbidade em pacientes encaminhados para anastomose intestinal. É necessário garantir o diagnóstico precoce desta complicação, prevenir abscessos e peritonites secundárias, proporcionando tratamento adequado e até mesmo reduzindo a mortalidade associada. Recomendamos incluir a procalcitonina no protocolo de avaliação no terceiro dia de seguimento pós-operatório.

ABSTRACT

RESUMEN Antecedentes: la fístula anastomótica (FA) es una de las complicaciones más severas de la cirugía colo rrectal. Su desarrollo obedece a múltiples factores dependientes del paciente y la técnica operatoria; entre estos últimos podemos mencionar la vascularización de los cabos como uno de los principales. La angiografía fluorescente (AF) permite la evaluación de ese factor en tiempo real durante la cirugía. Objetivo: describir la experiencia en el uso de la AF durante la cirugía colorrectal en un Hospital Uni versitario de la ciudad de Buenos Aires, registrar el cambio de conducta quirúrgica inducido por el uso de la AF y la incidencia de FA. Material y métodos: entre enero de 2016 y junio de 2018 se incluyeron 37 pacientes sometidos a resecciones colónicas programadas y con evaluación de la perfusión con AF. Resultados: la AF pudo realizarse en todos los pacientes con un tiempo operatorio extra de 3 a 9 mi nutos, registrando un cambio de conducta en 4 (10,81%) pacientes. Se registraron 2 (5,41%) fístulas anastomóticas. Conclusiones: la AF con verde de indocianina durante la cirugía colorrectal fue factible, sumó mínima complejidad y tiempo a la operación tradicional, y permitió cambiar la conducta en la sección intestinal en el 11% de los casos, con baja tasa de fístulas anastomóticas.

ABSTRACT

PURPOSE: Hyperthermic intraperitoneal chemotherapy (HIPEC) is a novel treatment option for peritoneal surface malignancies. Due to cytotoxic effects of chemotherapeutic agents, anastomosis healing can be impaired and lead to leakage rates higher than conventional intestinal surgery. In this experimental study, we aimed to investigate the effects of platelet-rich plasma (PRP) on colonic anastomosis in rats that received HIPEC with oxaliplatin.METHODS: Thirty rats were divided into 3 groups. Group 1 was determined as control group and hyperthermic saline perfusion was performed after colon anastomosis. In group 2, colon anastomosis then hyperthermic oxaliplatin perfusion was performed. In the last group, the colonic anastomosis was enhanced by PRP gel and then hyperthermic oxaliplatin perfusion was performed. All the rats were reoperated on postoperative day 7 and anastomotic bursting pressure values were recorded. Tissue samples were taken for hydroxyproline assay and histopathological examination.RESULTS: Control group had higher anastomotic bursting pressure value than group 2 and group 3 (P < 0.001). There were significant differences in anastomotic bursting pressure between groups 2 and 3 (P < 0.001). Group 2 had significantly lower hydroxyproline levels than group 3 and control group (P < 0.001). Histopathological examination revealed that PRP application reduced inflammatory response.CONCLUSION: PRP application on colonic anastomosis improves anastomotic healing and can reduce anastomosis related complications and stoma creation; though further clinical studies are needed.

ABSTRACT

The presence of bowel contents during colorectal surgery has been related to surgical site infections (SSI), anastomotic leakage (AL) and postoperative complications theologically. Mechanical bowel preparation (MBP) for elective colorectal surgery aims to reduce fecal materials and bacterial count with the objective to decrease SSI rate, including AL. Based on many observational data, meta-analysis and multicenter randomized control trials (RTC), non-MBP did not increase AL rates or SSI and other complications in colon and even rectal surgery. In 2011 Cochrane review, there is no significant benefit MBP compared with non-MBP in colon surgery and also no better benefit MBP compared with rectal enemas in rectal surgery. However, in surgeon's perspectives, MBP is still in widespread surgical practice, despite the discomfort caused in patients, and general targeting of the colon microflora with antibiotics continues to gain popularity despite the lack of understanding of the role of the microbiome in anastomotic healing. Recently, there are many evidence suggesting that MBP+oral antibiotics (OA) should be the growing gold standard for colorectal surgery. However, there are rare RCT studies and still no solid evidences in OA preparation, so further studies need results in both MBP and OA and only OA for colorectal surgery. Also, MBP studies in patients with having minimally invasive surgery (MIS; laparoscopic or robotics) colorectal surgery are still warranted. Further RCT on patients having elective left side colon and rectal surgery with primary anastomosis in whom sphincter saving surgery without MBP in these MIS and microbiome era.

ABSTRACT

PURPOSE: Anastomotic leakage (AL) is a type of intra-abdominal infection (IAI) which requires appropriate antibiotics with proper intervention. This study aimed to improve the appropriateness of antibiotic treatment by assessing the patterns of antibiotic treatment and resistance of pathogen profiles in patients who had AL after colorectal cancer surgery.METHODS: From June 2006 through December 2017, the medical records of the patients who had AL after elective abdominal surgery for colorectal cancer in Kyung Hee University Hospital at Gangdong, Seoul, Korea were reviewed retrospectively. Baseline characteristics and consistence of antibiotics with culture study results were analyzed to evaluate the appropriateness of treatment.RESULTS: Among 982 patients who underwent primary surgery for colorectal cancer, 41 (4.2%) had AL. Mean time of diagnosis of AL from surgery was 6.3 days. The most commonly used prophylactic antibiotics for the primary surgery was 2nd generation cephalosporin (66.6%). Mean duration of prophylactic antibiotics usage was 2.8 days. The most commonly used empirical antibiotics after AL occurred was piperacillin and tazobactam (32.6%). Mean duration of empirical antibiotics usage was 8.2 days. The most commonly identified pathogens were Escherichia coli and Enterococci spp. (26.8% each), and 12.2% of the “ESKAPE” pathogens were identified. Resistance to empirical antibiotics was 45.5% (10/22).CONCLUSION: Penetration of culture study for AL after colorectal cancer surgery appeared relatively low, although the profile of pathogens isolated from the AL patients can give important clues and evidence for appropriate antibiotics use. Surgeons should pay attention in performing culture studies for IAI including AL for proper patient treatment.

ABSTRACT

PURPOSE: Whether subtotal or total colectomy with primary anastomosis (PA) is safer than Hartmann procedure (HP) for left-sided colon cancer obstruction or perforation remains controversial. The purpose of this study was to compare postoperative morbidity, mortality, and defecation frequency between PA and HP for left-sided colon cancer obstruction or perforation.METHODS: This retrospective study enrolled 54 patients from January 2014 to February 2018 who underwent emergency surgery due to left-sided colon cancer obstruction or perforation.RESULTS: PA was carried out in 20 patients while HP was performed for 34 patients. Thirty-day mortality did not show significant difference between the two groups (15.0% vs. 14.7%, P=1.000). No anastomotic leakage occurred in PA group while three (8.8%) cases of stump leakage occurred in HP group. Stoma repair was performed for 13 cases (44.8%) and stoma reformation was performed for one case in HP group (7.7%). Stoma related complications occurred in five cases (17.24%). For patients after stoma repair, defecation frequency at 3 months after operation was 2.91±2.88 times per day in PA group and 2.86±2.63 times per day in HP group. At 1 year after operation, defecation frequency was changed to 1.40±1.12 times per day in PA group and 1.17±0.39 times per day in HP group.CONCLUSION: Primary ileosigmoid or ileorectal anastomosis for left-sided colon cancer obstruction or perforation is safe, and shows similar outcome of defecation frequency compared to HP.

ABSTRACT

PURPOSE: The laparoscopic transhiatal approach (LA) for adenocarcinoma of the esophagogastric junction (AEJ) is advantageous since it allows better visualization of the surgical field than the open approach (OA). We compared the surgical outcomes of the 2 approaches. MATERIALS AND METHODS: We analyzed 108 patients with AEJ who underwent transhiatal distal esophagectomy and gastrectomy with curative intent between 2003 and 2015. Surgical outcomes were reviewed using electronic medical records. RESULTS: The LA and OA were performed in 37 and 71 patients, respectively. Compared to the OA, the LA was associated with significantly shorter duration of postoperative hospital stay (9 vs. 11 days, P=0.001), shorter proximal resection margins (3 vs. 7 mm, P=0.004), and extended operative times (240 vs. 191 min, P=0.001). No significant difference was observed between the LA and OA for intraoperative blood loss (100 vs. 100 mL, P=0.392) or surgical morbidity rate (grade≥II) for complications (8.1% vs. 23.9%, P=0.080). Two cases of anastomotic leakage occurred in the OA group. The number of harvested lymph nodes was not significantly different between the LA and OA groups (54 vs. 51, P=0.889). The 5-year overall and 3-year relapse-free survival rates were 81.8% and 50.7% (P=0.024) and 77.3% and 46.4% (P=0.009) for the LA and OA groups, respectively. Multivariable analyses revealed no independent factors associated with overall survival. CONCLUSIONS: The LA is feasible and safe with short- and long-term oncologic outcomes similar to those of the OA.

ABSTRACT

PURPOSE: Transient loop ileostomies in rectal cancer surgery are generally closed after 2 or more months to allow adequate time for anastomotic healing. Maintaining the ileostomy may cause medical, surgical, or psychological complications; it also reduces the quality of life, and increase treatment costs. We performed this study to evaluate the safety and feasibility of early ileostomy closure 2 weeks postoperatively. METHODS: If a patient who underwent total mesorectal excision had 2 or more risk factors for anastomotic leakage, a loop ileostomy was created. After confirmation of intact anastomosis via sigmoidoscopy and proctography 1 week postoperatively, the patient was enrolled and ileostomy was closed 2 weeks postoperatively. The primary endpoint was the frequency of complication after ileostomy repair. RESULTS: Thirty patients were enrolled in the study and 6 were excluded due to anastomotic leakage. Except for 1 case of wound infection (4.2%), no patient experienced any complication including newly developed leakage after the ileostomy closure. The mean duration to repair was 13.1 days (range, 8–16 days) and mean duration to the start of adjuvant treatment after radical surgery was 5.37 weeks (range, 3.0–8.1 weeks). CONCLUSION: Transient loop ileostomy, which is confirmed to be intact endoscopically and radiologically, can be safely closed 2 weeks postoperatively without requiring a significant delay in adjuvant chemotherapy.

ABSTRACT

BACKGROUND: Neoadjuvant chemoradiation therapy (nCRT) has become the standard of care for esophageal cancer patients prior to esophagectomy. However, the optimal timing for surgery after completion of nCRT remains unclear. METHODS: A retrospective review was performed of patients who underwent esophagectomy with cervical anastomosis for esophageal cancer at a single institution between January 2000 and June 2015. Patients were categorized into 3 cohorts: those who did not receive nCRT prior to esophagectomy (no nCRT), those who underwent esophagectomy within 35 days after nCRT (≤35d), and those who underwent esophagectomy more than 35 days after nCRT (>35d). RESULTS: A total of 366 esophagectomies were performed during the study period, and 348 patients met the inclusion criteria. Anastomotic leaks occurred in 11.8% of all patients included in the study (41 of 348). Within each cohort, anastomotic leaks were detected in 14.7% of patients (17 of 116) in the no nCRT cohort, 7.3% (13 of 177) in the ≤35d cohort, and 20.0% (11 of 55) in the >35d cohort (p=0.020). Significant differences in the occurrence of anastomotic leaks were observed between the no nCRT and ≤35d cohorts (p=0.044), and between the ≤35d and >35d cohorts (p=0.007). CONCLUSION: Esophagectomy with cervical anastomosis within 35 days of nCRT resulted in a lower percentage of anastomotic leaks.

ABSTRACT

Endoscopic ultrasound (EUS)-guided transgastric drainage has been performed as a less invasive procedure for pancreatic fistulas and intra-abdominal abscesses occurring after surgery in recent years. However, there are no reports of EUS-guided transgastric drainage of intra-abdominal abscesses following gastrectomy. This case report describes 2 patients who developed an intra-abdominal abscess following gastrectomy and underwent EUS-guided transgastric drainage. Both patients underwent laparoscopy-assisted distal gastrectomy with Billroth-I reconstruction for gastric cancer. The intra-abdominal abscesses were caused by postoperative pancreatic fistula that developed following gastrectomy. One patient underwent naso-cystic drainage and the other underwent only a needle puncture of the abscess cavity. EUS-guided drainage was performed safely and effectively, although 1 patient developed gastroduodenal anastomotic leakage related to this procedure. In summary, EUS-guided transgastric drainage is safe and technically feasible even in post-gastrectomy patients. However, it is necessary to be careful if this procedure is performed in the early period following gastrectomy.

ABSTRACT

BACKGROUND/AIMS: Bile leak is one of the most common complications of liver transplantation. The treatment options for bile leaks include conservative management, surgical re-intervention, percutaneous drainage and endoscopic drainage. We aimed to perform a systematic review to identify the efficacy of endoscopic treatment in the resolution of post-transplant bile leaks. METHODS: Two independent reviewers performed systematic literature search in PubMed, ISI Web of Science, grey literature and relevant references in May 2017. Human studies in English with documented post-liver transplant bile leaks were included. RESULTS: Thirty-four studies were included in the final analysis. The pooled efficacy of biliary stents for the resolution of post-transplant bile leaks was 82.43% compared with 87.15% efficacy of nasobiliary tubes. The efficacy of biliary stents was lower for anastomotic leaks (69.23%) compared to T-tube (90.9%) or cut-surface/ cystic duct stump related leaks (92.8%). Similarly, the efficacy of nasobiliary tube was also lower for anastomotic leaks (58.33%) compared to T-tube or cut-surface related leaks (100%). CONCLUSIONS: In this systematic review, the overall efficacy was 82.43% in biliary stent group, and 87.15% in nasobiliary tube group. Both biliary stent and nasobiliary tube were more effective in managing non-anastomotic leaks compared to anastomotic leaks.

ABSTRACT

OBJECTIVE@#To investigate the risk factors of postoperative pulmonary infection (PPI) in patients over 60 years of age with gastric cancer after radical gastrectomy.@*METHODS@#Clinicopathological data of 373 patients over 60 years of age who underwent radical gastrectomy at Department IV of Gastrointestinal Cancer Center, Peking University Cancer Hospital, from April 2009 to December 2016 were retrospectively collected in this case-control study. The clinicopathological characteristics of patients with postoperative pulmonary infection (including postoperative atelectasis) and those without pulmonary infection were compared. A Student t-test (reported as Mean±SD if data matching normal distribution) or Mann-Whitney U test [reported as median (quartile) if data did not conform to normal distribution] was used to analyze continuous variables. A χ² test or Fisher exact tests (reported as number and percentage) was used for categorical variables. Multivariable logistic regression was used to analyze the risk factors for pulmonary infection after operation of gastric cancer.PPI was defined as postoperative patients with elevated body temperature (>38.0 degrees centigrade) for more than 24 hours; cough and expectoration; positive sputum bacteria culture;recent infiltration, consolidation or atelectasis confirmed by chest imaging examination.@*RESULTS@#Among 373 patients, 50 cases had PPI(13.4%, PPI group), 323 cases had no PPI(86.6%, non-PPI group). There were 39 (78.0%) and 178(55.1%) patients with comorbidities (including hypertension, diabetes and cardiopulmonary disease) preoperatively in PPI and non-PPI group, respectively. The difference between two groups was statistically significant (χ²=9.325,P=0.002). The incidence of preoperative hypoalbuminemia in PPI group was also significantly higher than that in non-PPI group [10.0%(5/50) vs. 3.1% (10/323),χ²=4.098, P=0.048]. Compared to non-PPI group, the rate of total gastrectomy [54.0%(27/50) vs. 34.4% (111/323), χ²=12.501, P=0.002], postoperative wound pain [34.0%(17/50) vs. 11.8% (38/323),χ²=16.928, P<0.001], secondary operation [6.0%(3/50) vs. 0.6% (2/323), χ²=6.032, P=0.014] and the rate of gastric tube removal later than 7 days postoperatively [96.0%(48/50) vs. 84.5%(273/323),χ²=4.811, P=0.028] were significantly higher in PPI group, respectively. The postoperative hospital stay was also prolonged in PPI group [16.0(9.5) days vs. 12.0(5.0) days, U=4 275.0, P<0.001]. Multivariate logistic regression analysis showed that preoperative comorbidities (OR=4.008, 95%CI:1.768-9.086, P=0.001), abdominal infection (OR=3.164, 95%CI:1.075-9.313, P=0.037), and wound pain (OR=3.428, 95%CI:1.557-7.548, P=0.002) were independent risk factors for PPI in patients over 60 years of age with gastric cancer. Furthermore, 50 patients with pulmonary infection were classified according to the length of latency and the type of infection. The patients with PPI latency ≤ 3 days were classified as early onset (34 cases, 68.0%), and those with latency ≥ 4 days as delayed onset (16 cases, 32.0%); PPI combined with surgical infection (including anastomotic leakage, abdominal infection, duodenal stump leakage, wound infection, etc.) was classified into mixed infection group (13 cases, 26.0%), with non-surgical infection as simple infection group (37 cases, 74.0%). The results showed that the pulmonary infection occurred 0 to 12 days (median 3 days) before surgical infection in mix infection group. The incidence of previous chronic obstructive pulmonary disease (COPD) in patients with early onset was significantly higher than that in patients with delayed onset [17.6%(6/34) vs. 0, χ²=5.005, P=0.025], and the incidence of mixed infection in patients with delayed onset was significantly higher than that in patients with early onset [50%(8/16) vs. 14.7%(5/34), χ²=6.730, P=0.009],but there was no significant difference in postoperative hospital stay between the two groups[17.0(9.8) days vs. 14.0(9.5) days, U=224.0, P=0.317].@*CONCLUSIONS@#Postoperative pulmonary infection is common in gastric cancer patients over 60 years of age. Preoperative comorbidities, abdominal infection and wound pain are independent risk factors for postoperative pulmonary infection. Pulmonary infection within 3 days after operation is associated with preoperative COPD. For patients suffering from PPI after the 4th day,attentions should be paid to abdominal infection and anastomotic leakage.

ABSTRACT

PURPOSE: To compare high and low inferior mesenteric artery (IMA) ligation in a large number of patients, and investigate the short-term and long-term outcomes. METHODS: This retrospective study compared outcomes between high IMA ligation and low IMA ligation with dissection of lymph nodes (LNs) around the IMA origin. A total of 1,213 patients underwent elective low anterior resection with double-stapling anastomosis for stage I–III rectal cancer located ≥6 cm from the anal verge (835 patients underwent IMA ligation at the IMA origin; 378 patients underwent IMA ligation directly distal to the root of the left colic artery along with dissection of LNs around the IMA origin). RESULTS: There was no difference in anastomotic leakage rate between groups. The 2 groups did not significantly differ in intraoperative blood loss, perioperative complications, total number of harvested LNs, and metastatic IMA LNs. However, more metastatic LNs were harvested in the high-tie than in the low-tie group (1.3 ± 2.9 vs. 0.8 ± 1.9, P = 0.002), and the incidence of positive pathologic nodal status was higher in the high-tie group (37.9% vs. 28.6%, P = 0.001). The 5-year local recurrence-free and metastasis-free survival rates were similar between groups, as were the 5-year overall and cancer-specific survival rates. CONCLUSION: Low IMA ligation with dissection of LNs around the IMA origin showed no differences in anastomotic leakage rate compared with high IMA ligation, without affecting oncologic outcomes. High IMA ligation did not seem to increase the number of total harvested LNs, whereas the ratio of metastatic apical LNs were similar between groups.
