RESUMO
PURPOSE: Defunctioning loop ileostomy has been reported to reduce symptomatic anastomotic leakage after rectal cancer surgery; however, stoma outlet obstruction (SOO) is a serious postileostomy complication. We, therefore, explored novel risk factors for SOO in defunctioning loop ileostomy after rectal cancer surgery. METHODS: This is a retrospective study that included 92 patients who underwent defunctioning loop ileostomy with rectal cancer surgery at our institution. Among them, 77 and 15 ileostomies were created at the right lower abdominal and umbilical sites, respectively. We defined the output volumeMAX as the maximum output volume the day before the onset of SOO or-for those without SOO-that was observed during hospitalization. Univariate and multivariate analyses were performed to evaluate risk factors for SOO. RESULTS: SOO was observed in 24 cases, and the median onset was 6 days postoperatively. The stoma output volume in the SOO group was consistently higher than that in the non-SOO group. In the multivariate analysis, the rectus abdominis thickness (p < 0.01) and output volumeMAX (p < 0.01) were independent risk factors for SOO. CONCLUSION: A high-output stoma may predict SOO in patients with defunctioning loop ileostomy for rectal cancer. Considering that SOO occurs even at umbilical sites with no rectus abdominis, a high-output stoma may trigger SOO primarily.

PURPOSE: Stoma construction and closure are common surgical strategies in patients with colorectal cancer. The present study evaluated the influence of multiple incisional sites resulting from stoma closure on incisional hernia after colorectal cancer surgery. METHODS: The study included 1681 patients who underwent colorectal cancer surgery. Multiple incisional sites were defined as the coexistence of incisions at the midline and stoma closure sites. We retrospectively investigated the relationship between the presence of multiple incisional sites and incisional hernia development in patients with colorectal cancer. RESULTS: Among the 1681 patients, 420 (25%) underwent stoma construction, with a stoma closure-to-construction ratio of 33% (139/420), and 155 (9.2%) developed incisional hernias after colorectal cancer surgery. In the multivariate analysis, female sex (p < 0.001), body mass index (p < 0.001), multiple incisional sites (p = 0.001), wound infection (p = 0.003), and postoperative chemotherapy (p = 0.030) were independent predictors of incisional hernia. In the multiple incisional sites group, the age (p < 0.001), surgical approach (laparoscopic) (p = 0.013), wound infection rate (p = 0.046), small bowel obstruction rate (p < 0.001), and anastomotic leakage rate (p = 0.008) were higher in those in the single incisional site group. CONCLUSIONS: Multiple incisional sites resulting from stoma closure are associated with the development of incisional hernia following colorectal cancer surgery.
RESUMO
PURPOSE: Systemic inflammatory response has been reported to be associated with prognosis in cancer patients. The aim of this study is to investigate the association between Systemic Immune-Inflammation Index (SII), a novel inflammation-based prognostic score and long-term outcomes among patients with colorectal cancer (CRC) after resection. METHODS: We retrospectively investigated 733 patients who underwent resection for CRC between January 2010 and December 2014 at the Jikei University Hospital and explored the relationship between SII, calculated by multiplying the peripheral platelet count by neutrophil count and divided by lymphocyte count, and overall survival. In survival analyses, we conducted Cox proportional hazards models, adjusting potential confounders including TNM stage, serum CEA, serum CA 19-9, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, and platelet count. RESULTS: In multivariate analysis, age ≥ 65 years (p = 0.003), tumor location (p = 0.043), advanced TNM stage (p < 0.001), serum CA 19-9 > 37 mU/ml (p < 0.001), and SII (P for trend = 0.017) were independent and significant predictors of poor patient survival. Compared to patients with low SII, those with high and intermediate SII patients had poorer survival (Hazard ratio 2.48; 95% CI 1.31-4.69, Hazard ratio 1.65; 95% CI 0.83-3.27, respectively). CONCLUSION: The Systemic Immune-Inflammation Index might be an independent and significant indicator of poor long-term outcomes in patients with CRC after resection.

RESUMO
PURPOSE: In rectal cancer surgery, an insufficient distal margin (DM) is associated with a high risk of local recurrence, whereas an excessive DM will cause low anterior resection syndrome, impairing quality of life. This study aimed to identify the factors that affect the distance between the colorectal resection site and the tumor to optimize achieving the correct DM. METHODS: The subjects of this study were 219 patients who underwent resection for primary rectal cancer in our department between January 2006 and July 2014. According to Japanese guidelines, DM (rDM) was based on the tumor location, but the pathological DM (pDM) was measured from surgical specimens. The patients were divided into two groups: the pDM-less-than-rDM group (pDM < rDM) and the pDM-greater-or-equal-to-rDM group (pDM ≥ DM). The factors associated with the DM in the two groups were compared. RESULTS: In the pDM < rDM group, the tumor distance from the anal verge was shorter (p = 0.001) and significantly more patients underwent laparotomy (p = 0.047). CONCLUSION: The DM tended to be shorter than that planned by the surgeon in patients with lower rectal cancers and those treated by laparotomy,; therefore, when performing rectal resection, care must be taken to ensure that the pDM is not shorter than the rDM.

PURPOSE: Anastomotic leakage (AL) and surgical site infection (SSI) are prevalent complications of colorectal surgery. To lower this risk, we standardized our surgical procedures in 2012, with a preferential use of laparoscopic approach (LS) for both colon and rectal surgery, combined with triangulating anastomosis (TA) for colon surgery and defunctioning ileostomy (DI) for low anterior resection. Our aim was to evaluate the outcomes of our standardized procedures. METHODS: The incidence rate of AL (primary outcome) and of reoperation and SSI (secondary outcome) was compared before (early period, n = 648) and after (late period, n = 541) standardization, through a retrospective analysis. RESULTS: The incidence rate of AL (6.6 versus 1.8%; P = 0.001), reoperation (3.5 versus 0.7%; P = 0.0012), and SSI (7.7 versus 4.6%; P = 0.029) was lower in late than in the early period. For colon cancer, TA and LS reduced the risk of AL (2.1 versus 0.3%, P = 0.020, for TA, and 3.2 versus 0.4%, P = 0.0027, for LS) and reoperation (2.9 versus 0.3%, P = 0.003, for TA, and 2.5 versus 0.2%, P = 0.0040, for LS). For rectal cancer, the incidence of all adverse outcomes (AL, reoperation, and SSI) was lower in cases treated by LS. However, the incidence of AL was lower in the late than in early period (P = 0.002) and with LS (P = 0.002). On multivariate analysis, late period and LS were independent factors of a lower risk of adverse outcomes. CONCLUSIONS: Our surgical standardization seems to be effective in lowering the risks of AL, reoperation, and SSI after colorectal cancer surgery.

BACKGROUND: The C-reactive protein (CRP)-albumin-lymphocyte (CALLY) index is a novel immuno-nutritional biomarker based on the levels of CRP, serum albumin, and lymphocyte count. This study examined the prognostic value of the CALLY index in patients with colorectal cancer undergoing curative surgery. METHODS: Between 2010 and 2017, 578 patients with stage II-III colorectal cancer who underwent curative resection were enrolled. The CALLY index was defined as (albumin × lymphocyte)/(CRP × 104). We investigated the association of the CALLY index with disease-free survival (DFS) and overall survival (OS). RESULTS: The cutoff value of the CALLY index was determined to be 2. Of the 578 patients, 175 (30%) had a preoperative CALLY index <2. In multivariate analysis, the pre-operative carcinoembryonic antigen (CEA) level (p = 0.003), cell differentiation (p = 0.045), venous invasion (p = 0.036), Tumor-Node-Metastasis stage (p < 0.001), and CALLY index score <2 (p = 0.006) were independent predictors of DFS. Meanwhile, preoperative carbohydrate antigen (CA)19-9 levels (p = 0.019), lymphatic invasion (p = 0.018), preoperative platelet (p = 0.037), and CALLY index score <2 (p = 0.007) were independent predictors of OS. CONCLUSION: The CALLY index may be an independent prognostic biomarker for long-term outcomes in patients with colorectal cancer.

BACKGROUND/AIM: The prognostic outcome of the controlling nutritional status (CONUT) score in patients with colorectal liver metastases (CRLM) who underwent hepatectomy has not been investigated. The aim of this study was to investigate the prognostic value of preoperative CONUT score and other systemic inflammation-related biomarkers in patients who underwent hepatectomy for CRLM. PATIENTS AND METHODS: The subjects included 145 patients with CRLM who underwent hepatectomy and retrospectively investigated the association of preoperative CONUT score with disease-free survival (DFS), surgical failure-free survival (SFS), and overall survival (OS) using univariate and multivariate analyses. RESULTS: In this study, the cut-off of the CONUT score was 4. In the univariate analysis, the high CONUT score was associated with worse SFS and OS (p=0.01, 0.01). The multivariate analysis showed significant and independent predictors of OS were lymph node metastases (p=0.03) and a high CONUT score (p=0.04). In patients with a high CONUT score, postoperative complications due to infections were significantly more than in those with a low CONUT score (27% vs. 9%, p=0.04). CONCLUSION: The CONUT score can be useful for predicting not only short-term but also long-term outcomes in patients with CRLM after hepatectomy.

BACKGROUND/AIM: Surgery for dialysis patients requires special attention because of their physical characteristics. This study aimed to investigate the short-term postoperative outcomes of colorectal cancer patients with chronic renal failure (CRF) on dialysis and aimed to investigate safer treatment options for these patients. PATIENTS AND METHODS: A total of 1,504 colorectal cancer patients who underwent primary resection between January 2008 and December 2018 were included. A retrospective analysis of clinical data, preoperative tumor markers (carcinoembryonic antigen and carbohydrate antigen 19-9), and the Clavien-Dindo (CD) classification was performed. Patients were stratified into Groups A and B based on their need for dialysis or not, respectively. RESULTS: There were 20 and 1,484 patients in Groups A and B, respectively. No differences were observed regarding age, body mass index, and preoperative tumor markers. The rate of laparoscopic surgery was significantly lower in Group A than in Group B. There was one mortality in Group A due to pulmonary disease. Group A had a significantly higher rate of complications. CONCLUSION: CRF patients on dialysis who underwent colorectal cancer surgery tended to be ruled out of laparoscopic surgery, and their rates of postoperative complications were higher.

We reviewed the results of local surgical treatment of stoma prolapse, a long-term complication of stoma construction. Fifteen patients treated for stomal prolapse between 2009 and 2020 at the authors' and affiliated hospitals were included in this study. The treatment comprised local laparotomic stomal reconstruction (LLSR) in nine patients and stapling repair (SR) in six. We compared and evaluated the clinical and surgical information and postoperative complications. Operation time was significantly shorter in the SR group than in the LLSR group: 20 and 53 min, respectively (p = 0.036). The duration of postoperative hospitalization was shorter in the SR group than in the LLSR group: 5.5 and 8 days, respectively; the difference was not significant (p = 0.088). No short-term complications were found in either group. Regarding long-term, postoperative complications, parastomal hernias developed after 2.5 years in one patient in the LLSR group and after 6 months in one patient in the SR group; both patients had histories of parastomal hernia surgery and had relatively high body mass indices. Local surgery for stomal prolapse was minimally invasive and performed safely. In patients with a history of surgery for parastomal hernia, attention must be paid to the potential of parastomal hernia developing as a postoperative complication.
RESUMO
BACKGROUND/AIM: Umbilical defunctioning ileostomy (UDI) spares one incision, which may reduce the overall incidence of incisional hernia. Our aim was to evaluate the occurrence and risk factors of incisional hernias between UDI and conventional defunctioning ileostomy (CDI) after ileostomy closure. PATIENTS AND METHODS: Incidence of incisional hernia after ileostomy closure was compared between UDI (n=51) and CDI (n=86) groups. Risk factors for incisional hernia were also considered through a retrospective analysis. RESULTS: The overall incidence of incisional hernia was 5.9% in the UDI group, which was significantly lower than the 22.1% (7.0% at the midline incision and 15.1% at the stoma site) in the CDI group (p=0.012). Multivariate analysis showed higher BMI (p=0.035) and CDI (p=0.031) as risk factors for developing incisional hernias overall. CONCLUSION: UDI results in fewer incisional hernias than CDI and seems to be superior to CDI from the standpoint of overall incidence of incisional hernias.

UNLABELLED: The aim of this retrospective study was to determine clinicopathological factors pertinent to the prognosis of perforated colorectal cancer (PCRC). PATIENTS AND METHODS: A retrospective review of clinical records of 17 cases of emergency primary resection for PCRC (stage IIIa in 2, stage IIIb in 6 and stage IV in 9) was performed. RESULT: The 5-year survival rate was 31% (31% for stage III and 12% for stage IV). When compared with non-PCRC (533 cases) in stage III (78.8%) or stage IV (14.8%), the 5-year survival rate of stage III perforated colorectal cancer was clearly worse (p<0.01) than the non-perforated counterpart. For stage IV, however, the two groups had a similar prognosis. MST of the PCRC was 31 months for stage III and 12 months for stage IV. Approximately half of the recurrence pattern of stage III (75%), or stage IV (44%) PCRC was peritoneal carcinomatosis. As for the type of operations performed, Hartmann's procedure was the preferred technique (71%), for which mortality and morbidity rate were both low. CONCLUSION: Because of the high incidence of peritoneal carcinomatosis and low 5-year survival rate, stage III PCRC should be regarded as a stage IV disease, for which postoperative chemotherapy seems essential.

BACKGROUND/AIM: This study aimed to identify risk factors for recurrence of patients with stage III colorectal cancer by assessing clinicopathological features. PATIENTS AND METHODS: The study included 231 patients with stage III colorectal cancer who underwent curative resection between 2006 and 2012 at the Department of Surgery of the Jikei University Hospital, Tokyo, Japan. Clinicopathological data of the patients were retrospectively evaluated. RESULTS: The recurrence rate was 27.7% (64/231) in the study group. The univariate analysis for recurrence identified five risk factors: site of primary tumor (rectal cancer), surgical procedure (open surgery), preoperative serum CEA level (>5 ng/ml), preoperative serum CA19-9 level (>37 U/ml), and number of metastatic lymph nodes (over three metastases). The multivariate analysis for recurrence identified three risk factors: rectal cancer, preoperative serum CEA level >5.0 ng/ml 95%, and more than three metastatic lymph nodes. CONCLUSION: The risk factors for stage III colorectal cancer recurrence seem to be rectal cancer, preoperative serum CEA level >5.0 ng/ml, and more than three metastatic lymph nodes.

BACKGROUND/AIMS: The aims of this study were to assess the prognosis and histopathological factors of poorly differentiated colorectal adenocarcinoma, and the clinical relevance of the proposed histopathological sub classifications. METHODOLOGY: Fifty eight patients with poorly differentiated adenocarcinoma were enrolled in this study. According to the lymphatic canal spread in tumor tissue, they were classified into lymphangitic type (tumor spread beyond the intra mucosal tumor space through the lymphatic canal widely) and non-lymphangitic type (tumor spread within that space). Next, they were sub classified into medullary, intermediate and scirrhous types according to the amount of fibrous stroma. In addition, immunohistological examinations were performed on the expression of an intercellular adhesion molecule (E-cadherin). RESULTS: In 33 cases (57%) Lymphangitic type was present and in 25 cases non-lymphangitic type (43%) was present. In the lymphangitic types, 5 cases were medullary type (15%), 17 cases were intermediate type (52%) and 11 cases were scirrhous type (33%) that included 2 cases of signet ring cell carcinoma. In the non-lymphangitic types, medullary type was dominant (20 cases, 80%) while intermediate type and scirrhous type were 3 cases (12%) and 2 cases (8%), respectively. The survival rates were calculated for both types and a large difference was found in terms of 5-year survival rate; 0% for lymphangitic type and 72% for non-lymphangitic type (p<0.05). There was no correlation found between the expression of cadherin and the subclassification. CONCLUSIONS: In conclusion, a wide tumor infiltration and growth in lymphatic vessels appears to be an important prognostic factor for poorly differentiated adenocarcinoma compared to the metastasis patterns.

BACKGROUND/AIM: Early postoperative small bowel obstruction (EPSBO) prolongs hospital stays after surgery. This study aimed to evaluate the risk factors for EPSBO associated with colorectal cancer resection. PATIENTS AND METHODS: We retrospectively compared the clinical variables of patients with EPSBO (n=37) and those without (n=812) after primary tumor resection for colorectal cancer at our hospital between January 2010 and December 2015. RESULTS: In multivariate analysis, significant differences between the two groups was found in male sex, open surgery, and defunctioning ileostomy (DI) placement (p=0.024, p<0.0001, and p=0.023, respectively), but not for colostomy placement. Of 16 patients with DI who developed EPSBO, 13 (81.3%) cases resulted from obstruction of the stomal outlet. CONCLUSION: Male sex, open surgery, and DI placement are risk factors for EPSBO after colorectal cancer resection. For patients with placement of DI, obstruction of the stomal outlet should be carefully considered.

BACKGROUND/AIM: In colon surgery, the anastomotic method is generally selected by surgeon's preferences or by local conditions. In this study, we retrospectively analyzed anastomotic complications to assess safe methods of anastomosis in colonic resection. PATIENTS AND METHODS: We retrospectively analyzed a total of 684 cases, performed between July 2003 and June 2013 in our Hospital. Anastomosis complications, such as leakage, stricture and bleeding, were analyzed in relation to the three methods of anastomosis, hand-sewn (HS), functional end-to-end (FEEA) and triangulating anastomosis (TRI). RESULTS: Univariate analysis indicated that the incidence of leakage was significantly lower in laparoscopic surgeries (p=0.034) and TRI (p=0.047). The results of the multivariable analysis indicated that anastomotic leakage was significantly less with TRI (p=0.029). CONCLUSION: In colon surgery, TRI seems to be associated with a low risk of anastomotic leakage compared to HS and FEEA.

BACKGROUND/AIM: The aim of this study was to evaluate the necessity of thoracic epidural analgesia (TEA) as enhanced recovery after surgery (ERAS) programs for laparoscopic colorectal surgery (LC). PATIENTS AND METHODS: We retrospectively compared between perioperative outcomes of patients who underwent LC with TEA (n=31) and with multimodal analgesia (MMA) (n=31). Furthermore, we also evaluated the patients' satisfaction by a questionnaire survey to the nurses. RESULTS: The only numeric rating scale (NRS) score on post-operative day (POD) 1 of the MMA group was significantly higher than that in the TEA group (p=0.002). In multivariate analysis, the factors that demonstrated significant correlation with hospital stay did not include analgesia. The 74% of the nurses felt equal or higher analgesic effect in the MMA group and interestingly, 84% of them answered that they would choose MMA if they were to undergo LC. CONCLUSION: TEA may not be necessary for ERAS in LC.

BACKGROUND/AIM: To determine the superiority of the laparoscopic vs. open technique for colorectal cancer surgery. PATIENTS AND METHODS: We performed a retrospective analysis of consecutive patients who underwent curative surgery by laparoscopic colectomy (LC) or open colectomy (OC) for colon cancer. The patients were classified into two groups: as LC group and OC group. We retrospectively assessed clinical characteristics, intraoperative and postoperative outcomes and long-term outcomes between the two groups by univariate analysis. RESULTS: The LC group had significantly less intraoperative blood loss, complications, and shorter post-operative hospital stay than the OC group. The overall survival of Stage II in the LC group is significantly longer than the OC group. DFS of Stage III in the LC group was significantly longer than the OC group. CONCLUSION: LC showed more favorable results in both short-term and long-term outcomes than OC.

We treated a patient with multiple liver metastases arising from colon cancer in whom the metastatic tumors were responsive to treatment with the combination of TS-1 and CPT-11. The patient was a 71-year-old woman with cancer of the ascending colon and metastatic hepatic tumors. She had undergone surgery on July 28, 2004, and abdominal contrast CT scans obtained after discharge from hospital revealed numerous LDA (low-density areas) in both lobes of the liver. The patient was given ambulatory chemotherapy with TS-1 (120 mg/day on days 1-14) and CPT-11 (100 mg/day on days 1 and 8). After completion of 2 courses of chemotherapy, abdominal contrast CT scans revealed that most of the LDAs in both lobes of the liver had disappeared, and the patient was judged to have achieved PR. No adverse reactions were observed except for a slight decrease of WBC, and her chemotherapy is being continued at present. This case suggests that the combination of TS-1 and CPT-11 may be an effective form of chemotherapy for the treatment of colon cancer with multiple hepatic metastases.
