RESUMO
INTRODUCTION: Cholinesterase is a classical marker that reflects nutritional and inflammatory status. The aim of the present study was to evaluate the association between serum cholinesterase levels and postoperative infectious complications in patients undergoing gastrectomy for gastric cancer. MATERIALS AND METHODS: This retrospective study comprised 108 patients who underwent gastrectomy for gastric cancer. We comprehensively investigated the association between clinicopathological variables and postoperative infectious complications after gastrectomy. Then patients were divided into the cholinesterase-high and -low groups to analyze their clinicopathological variables. Finally, we analyzed the types of infectious complications that were most associated with preoperative serum cholinesterase levels. RESULTS: Twenty-six patients (24%) developed postoperative infectious complications. Multivariate analysis revealed that serum cholinesterase levels (P = 0.026) and N stage (P = 0.009) were independent risk factors for postoperative infectious complications. In particular, the incidence of pneumonia (P = 0.001) was significantly higher in the cholinesterase-low group. Age (P = 0.023), cerebrovascular comorbidities (P = 0.006), serum cholinesterase levels (P = 0.013), and total gastrectomy (P = 0.017) were identified as independent risk factors for postoperative pneumonia. CONCLUSIONS: Preoperative serum cholinesterase levels were associated with postoperative pneumonia after gastrectomy for gastric cancer, suggesting the importance of preoperative nutritional assessment in gastric cancer surgery.

BACKGROUND: Cholinesterase is a classical nutritional and inflammatory marker. The aim of the present study was to evaluate the value of cholinesterase as a predictive marker for postoperative skeletal muscle loss after gastrectomy for gastric cancer. METHODS: The study comprised 68 patients who had undergone gastrectomy for gastric cancer. Skeletal muscle mass was evaluated using skeletal mass index, and major skeletal muscle loss was defined as less than or equal to the median change rate (1-year postoperative/preoperative) of skeletal mass index in all patients. We explored the relationship between postoperative major skeletal muscle loss and disease-free survival and overall survival. Then we investigated the relationship between change rate of skeletal muscle index and serum cholinesterase levels after gastrectomy. RESULTS: The median value of change rate of skeletal mass index was 0.93. Postoperative major skeletal muscle loss was significantly associated with disease-free survival after gastrectomy (P = 0.003). Although major skeletal muscle loss had worse overall survival, it was not significant (P = 0.058). The change rate of skeletal mass index and cholinesterase had a stronger positive correlation compared with other nutritional indices according to Spearman's rank correlation coefficient (r = 0.438, P ≤ 0.001). CONCLUSION: Evaluation of serum cholinesterase levels may be valuable for predicting postoperative skeletal muscle loss after gastrectomy, suggesting the importance of cholinesterase in postoperative nutritional management of patients with gastric cancer.
RESUMO
BACKGROUND: The geriatric nutritional risk index (GNRI) is a simple nutritional and inflammatory marker for older adults. The aim of the present study was to investigate the usefulness of the GNRI in older adults who underwent emergency gastrointestinal surgery. METHODS: This study included 206 older adults who had undergone emergency gastrointestinal surgery. We retrospectively investigated the relationship between the GNRI and postoperative complications. Univariate and multivariate analyses were performed to evaluate risk factors for postoperative complications. We then evaluated the association between GNRI and clinical variables among older adults undergoing emergency gastrointestinal surgery. RESULTS: Postoperatively, all complications occurred in 89 (43%) older adults, infectious in 53 (26%), and non-infectious in 36 (17%). In the multivariate analysis, age (p = 0.016), GNRI (p = 0.012), operative severity (p = 0.003), and operation time (p = 0.003) were independent risk factors for all postoperative complications. While the GNRI (p = 0.049) was an independent risk factor for infectious complications, age (p = 0.035) and bleeding volume (p = 0.035) were independent risk factors for postoperative non-infectious complications. In the low GNRI group, age (p = 0.029), serum C-reactive protein levels (p < 0.001), and proportion of sarcopenia (p < 0.001) were significantly higher, and the length of hospital stay (p < 0.001) was significantly longer than that in the high GNRI group. In Spearman's rank correlation coefficient, the skeletal mass index and the GNRI had a positive correlation (r = 0.415 and p < 0.001). CONCLUSION: The GNRI may be a predictor of postoperative infectious complications in older adults after emergency gastrointestinal surgery, suggesting the usefulness of the GNRI as a nutritional marker and sarcopenia-related parameter.

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
Dual-specificity tyrosine-regulated kinase 2 (DYRK2) is a protein kinase that phosphorylates p53-Ser46 and induces apoptosis in response to DNA damage. However, the relationship between DYRK2 expression and chemosensitivity after DNA damage in colorectal cancer has not been well investigated. The aim of the present study was to examine whether DYRK2 could be a novel marker for predicting chemosensitivity after 5-fluorouracil- and oxaliplatin-induced DNA damage in colorectal cancer. Here we showed that DYRK2 knockout decreased the chemosensitivity to 5-fluorouracil and oxaliplatin in p53 wild-type colorectal cancer cells, whereas the chemosensitivity remained unchanged in p53-deficient/mutated colorectal cancer cells. In addition, no significant differences in chemosensitivity to 5-fluorouracil and oxaliplatin between scramble and siDYRK2 p53(-/-) colorectal cancer cells were observed. Conversely, the combination of adenovirus-mediated overexpression of DYRK2 with 5-fluorouracil or oxaliplatin enhanced apoptosis and chemosensitivity through p53-Ser46 phosphorylation in p53 wild-type colorectal cancer cells. Furthermore, DYRK2 knockout decreased chemosensitivity to 5-fluorouracil and oxaliplatin in p53 wild-type xenograft mouse models. Taken together, these findings demonstrated that DYRK2 expression was associated with chemosensitivity to 5-fluorouracil and oxaliplatin in p53 wild-type colorectal cancer, suggesting the importance of evaluating the p53 status and DYRK2 expression as a novel marker in therapeutic strategies for colorectal cancer.

PURPOSE: Incisional hernia is a common complication after abdominal surgery, especially in obese patients. The aim of the present study was to evaluate the relationship between sarcobesity and incisional hernia development after laparoscopic colorectal cancer surgery. METHODS: In total, 262 patients who underwent laparoscopic colorectal cancer surgery were included in the present study. Univariate and multivariate analyses were performed to evaluate the independent risk factors for the development of incisional hernia. We then performed subgroup analyses to assess the impact of visceral obesity according to clinical variables on the development of incisional hernia in laparoscopic surgery for colorectal cancer surgery. RESULTS: Forty-four patients (16.8%) developed incisional hernias after laparoscopic colorectal cancer surgery. In the univariate analysis, the development of incisional hernia was significantly associated with female sex (P = 0.046), subcutaneous obesity (P = 0.002), visceral obesity (P = 0.002), sarcobesity (P < 0.001), and wound infection (P < 0.001). In the multivariate analysis, sarcobesity (P < 0.001) and wound infection (P < 0.001) were independent predictors of incisional hernia. In subgroup analysis, the odds ratio of visceral obesity was the highest (13.1; 95% confidence interval [CI], 4.51-37.8, P < 0.001) in the subgroup of sarcopenia. CONCLUSION: Sarcobesity may be a strong predictor of the development of incisional hernia after laparoscopic surgery for colorectal cancer, suggesting the importance of body composition in the development of incisional hernia.

PURPOSE: This systematic review and meta-analysis aimed to evaluate the effect of dialysis-dependent chronic kidney disease (CKD) on postoperative complications in colorectal cancer surgery. METHODS: In April 2023, we systematically searched PubMed, the Cochrane library, and Ovid for relevant studies on short-term outcomes of colorectal cancer surgery in patients with dialysis and analyzed the findings from these studies for meta-analysis. RESULTS: Our systematic and meta-analysis review identified seven studies involving 50713 patients. We showed that the dialysis group had higher rates of mortality (OR = 4.12, 95%CI: 2.75-6.20, P < 0.001), cardiac complications (OR = 2.45, 95%CI: 1.88-3.21, P < 0.001), and pneumonia (OR = 2.68, 95%CI: 1.83-3.93, P < 0.001). On the other hand, there were no differences in superficial/deep surgical site infection (SSI) (odds ratio [OR] = 1.17, 95%CI: 0.90-1.53, P = 0.230) and organ/space SSI (OR = 1.35, 95%CI: 1.00-1.82, P = 0.053) between the dialysis group and non-dialysis group. CONCLUSION: Our meta-analysis showed that dialysis-dependent CKD was associated with higher rates of mortality, cardiac complications, and pneumonia after colorectal cancer surgery. However, the limitations of this meta-analysis should be taken into consideration when interpreting the results.

PURPOSE: Cancer cachexia, a complex multifactorial syndrome associated with sarcopenia, negatively affects the quality of life and survival in patients with several cancers. We aimed to develop a new score for cachexia assessment and evaluate its effectiveness in the classification of patients undergoing radical resection for colorectal cancer. METHODS: This study included 396 patients who underwent radical resection for Stage I-III colorectal cancer. To develop the Cancer Cachexia Score (CCS), we analyzed predictive factors of cachexia status related to the development of sarcopenia and incorporated significant factors into the score. We then evaluated the relationship between CCS and survival after radical resection for colorectal cancer. RESULTS: As body mass index (P < 0.001), prognostic nutritional index (P = 0.005), and tumor volume (P < 0.001) were significantly associated with the development of sarcopenia, these factors were included in CCS. Using CCS, 221 (56%), 98 (25%), and 77 (19%) patients were diagnosed with mild, moderate, and severe cancer cachexia, respectively. In multivariate analysis, severe CCS (P < 0.001), N stage 1-2 (P < 0.001), and occurrence of postoperative complications (P = 0.007) were independent predictors of disease-free survival. Age ≥ 65 years (P = 0.009), severe CCS (P < 0.001), and N stage 1-2 (P < 0.001) were independent predictors of overall survival. CONCLUSIONS: CCS may be a useful prognostic factor for predicting poor survival after radical resection in patients with Stage I-III colorectal cancer.

PURPOSE: Cholinesterase is a nutritional marker associated with sarcopenia. The present study evaluated the relationship between cholinesterase and postoperative infectious complications in patients undergoing colorectal resection for colorectal cancer. METHODS: The study involved 231 patients who had undergone colorectal resection for colorectal cancer. We retrospectively investigated the relationship between preoperative serum cholinesterase levels and postoperative infectious complications. Univariate and multivariate analyses were performed to identify independent risk factors for postoperative infectious complications. We then performed stratified analyses to assess the interaction between cholinesterase and clinical variables to predict postoperative infectious complications. RESULTS: In the multivariate analysis, the body mass index (P = 0.010), serum cholinesterase levels (P = 0.005), sarcopenia (P = 0.003) and blood loss (P < 0.001) were independent risk factors for postoperative infectious complications. In stratified analyses, the association between serum cholinesterase levels and postoperative infectious complications differed by the sarcopenia status (Pinteraction = 0.006). CONCLUSION: Preoperative serum cholinesterase levels may be useful for predicting postoperative infectious complications in colorectal cancer surgery. The association differs by the sarcopenia status, suggesting a potential interaction between nutritional markers and sarcopenia.

PURPOSE: Nutritional and inflammatory status have been associated with postoperative recurrence and poor survival in patients with colorectal cancer. The aim of the present study is to investigate the relationship between serum cholinesterase levels and postoperative outcomes among patients who underwent curative resection for colorectal cancer. METHODS: The study comprised 174 patients who had undergone curative resection for colorectal cancer. We explored the relationship between preoperative serum cholinesterase levels and disease-free survival and overall survival after curative resection. Then patients were divided into the high-cholinesterase group (n = 102) and the low-cholinesterase group (n = 72) to analyze their clinicopathological variables including other nutritional markers and systemic inflammatory responses. RESULTS: In multivariate analysis, lymph node metastasis (P = 0.011) and serum cholinesterase levels (P < 0.01) were independent predictors of disease-free survival, while lymph node metastasis (P = 0.013), serum cholinesterase levels (P < 0.01), and carbohydrate antigen19-9 (P = 0.022) were independent predictors of overall survival. In the low-cholinesterase group, neutrophil to lymphocyte ratio, (P = 0.021), C-reactive protein to albumin ratio (P < 0.01), and distant metastasis (P < 0.01) were higher, and prognostic nutritional index (P < 0.01) was lower compared with the high-cholinesterase group. CONCLUSION: Preoperative low serum cholinesterase levels can be a prognostic factor for postoperative recurrence and poor prognosis in patients after curative resection for colorectal cancer, suggesting an important role of cholinesterase in the assessment of nutritional and inflammatory status in cancer patients.

PURPOSES: An accurate assessment of preoperative malnutrition in the elderly is critically important to predicting postoperative complications. The aim of this study is to evaluate the predictive value of the preoperative serum cholinesterase levels as a risk factor for postoperative complications in the elderly who have undergone emergency surgery. METHODS: The study comprised 60 elderly patients who had undergone emergency major gastroenterological surgery. We retrospectively investigated the relationship between the preoperative serum cholinesterase levels and postoperative complications (Clavien-Dindo classification ≥ II). Univariate and multivariate analyses were performed to evaluate the risk factors for postoperative complications. RESULTS: Thirty-three patients (55%) developed postoperative complications. According to the univariate analysis, hemoglobin (P = 0.018), albumin (P = 0.0036), cholinesterase (P < 0.001), C-reactive protein (P = 0.043), prognostic nutritional index (P = 0.0050), the Physiologic and Operative Severity Score for the enUmeration of Mortality and Morbidity (P < 0.001) and operation time (P = 0.042) were identified to be risk factors for postoperative complications. According to the multivariate analysis, low preoperative serum cholinesterase levels were found to be an independent risk factor for postoperative complications (P = 0.029). In the extremely elderly (80-95 years), the cholinesterase-low group had a higher complication rate compared to the cholinesterase-high group (77.8 vs 43.8%, P = 0.028). CONCLUSION: The preoperative serum cholinesterase levels may be a risk factor for postoperative complications in elderly patients after emergency surgery, thus suggesting the significance of cholinesterase in evaluating the nutritional status.

PURPOSE: The cachexia index is a novel biomarker of cancer cachexia. This systematic review and meta-analysis aimed to evaluate the prognostic impact of cachexia index on prognosis after surgery for gastrointestinal cancer. METHODS: In August 2023, we systematically searched PubMed, the Cochrane Library, and Ovid for relevant studies on the oncological outcome after gastrointestinal cancer surgery and analyzed the findings from these studies for meta-analysis. RESULTS: Our systematic and meta-analysis review identified eight studies involving 1876 patients. The number of patients with low cachexia index accounted for 813 patients (43.3%). We found that low cachexia index was associated with worse overall survival (pooled HR, 2.30; 95% CI, 1.85-2.87; z = 7.49; P < 0.001) and disease/relapse/progression-free survival (pooled HR, 1.77; 95% CI, 1.45-2.18; z = 5.50; P < 0.001). CONCLUSION: Our meta-analysis showed that cachexia index was associated with oncological outcome after gastrointestinal cancer surgery. However, the limitations of this meta-analysis should be taken into consideration when interpreting the results.

BACKGROUND: The aim of this study was to investigate the prognostic value of systematic inflammatory response in patients with lymph node-negative colorectal cancer. METHODS: We retrospectively investigated 245 patients with lymph node-negative colorectal cancer who underwent curative resection and evaluated the prognostic impact of systematic inflammatory response, which was represented by neutrophil-to-lymphocyte ratio (NLR), prognostic nutritional index (PNI), and C-reactive protein-to-albumin ratio (CAR). Then, the prognostic significance of the systematic inflammatory response on survival was analyzed using the Kaplan-Meier method in patients selected by propensity score matching (PSM) analysis. RESULTS: In the multivariate analysis, CAR ≥ .081 (P = .004) was independent predictors of disease-free survival, while American Society of Anesthesiologists physical status ≥3 (P = .049) and CAR ≥ .081 (P < .001) were independent predictors of overall survival. By PSM analysis, PSM-high-CAR was significantly associated with worse disease-free survival (P = .043) and overall survival (P = .041) in patients with lymph node-negative colorectal cancer. CONCLUSIONS: C-reactive protein-to-albumin ratio may be a significant indicator of poor long-term outcomes in patients with lymph node-negative colorectal cancer.
RESUMO
Aim: Osteopenia and sarcopenia, features of the aging process, are recognized as major health problems in an aging society. This study investigated the prognostic impact of osteosarcopenia, the coexistence of osteopenia and sarcopenia, in older adults undergoing curative resection for colorectal cancer. Methods: We retrospectively reviewed data of older adults aged 65-98 y who had undergone curative resection for colorectal cancer. Osteopenia was evaluated by bone mineral density measurement in the midvertebral core of the 11th thoracic vertebra on preoperative computed tomography images. Sarcopenia was evaluated by measuring the skeletal muscle cross-sectional area at the third lumbar vertebra level. Osteosarcopenia was defined as the coexistence of osteopenia and sarcopenia. We explored the relationship of preoperative osteosarcopenia with the disease-free and overall survival after curative resection. Results: Among the 325 patients included, those with osteosarcopenia had significantly lower overall survival rates than those with osteopenia or sarcopenia alone (P < 0.01). In the multivariate analysis, male sex (P = 0.045), C-reactive protein-to-albumin ratio (P < 0.01), osteosarcopenia (P < 0.01), pathological T4 stage (P = 0.023), and pathological N1/N2 stage (P < 0.01) were independent predictors of disease-free survival, while age (P < 0.01), male sex (P = 0.049), C-reactive protein-to-albumin ratio (P < 0.01), osteosarcopenia (P < 0.01), pathological T4 stage (P = 0.036), pathological N1/N2 stage (P < 0.01), and carbohydrate antigen 19-9 (P = 0.041) were independent predictors of overall survival. Conclusion: Osteosarcopenia was a strong predictor of poor outcomes in older adults undergoing curative resection for colorectal cancer, suggesting an important role of osteosarcopenia in an aging society.
RESUMO
BACKGROUND AND PURPOSE: Poor bowel preparation increases the difficulty of colonoscopy and affects lesion detection. In this study, we investigated the usefulness of a new bowel preparation method using polyethylene glycol electrolyte formulation containing ascorbic acid (PEG plus ascorbic acid: PEG-Asc, MOVIPREP) to improve bowel cleansing and shorten preparation time. METHODS: This was a single-center, retrospective study. In the new method, patients were instructed to take a laxative the day before the examination and PEG1L on the day of the examination. In addition, we instructed the patients to walk, which we designed. The primary endpoints were the degree of bowel cleansing (assessed by the Boston bowel preparation scale, BBPS) and time to the cecum. RESULTS: The conventional group reached the cecum in 606.5±225.8 seconds (mean±SD), whereas the introduced group reached the cecum in 500±217.1 seconds, a significantly shorter time ( P <0.05). In the BBPS, the score in the introduced group was significantly higher ( P <0.01): 6.8±2.14 points in the conventional group and 8.6±0.74 points in the introduction group. CONCLUSION: Pretreatment combining the 1L weight loss method and walking improves bowel cleansing and shortens the time to reach the cecum.

Aim: Frailty assessment in elderly patients is crucial to predict the postoperative course, considering that frailty is highly associated with postoperative complications and mortality. The aim of this study was to evaluate the value of osteopenia as a risk factor for severe postoperative complications in elderly patients who underwent emergency gastrointestinal surgery. Methods: This study comprised 103 elderly patients who underwent emergency gastrointestinal surgery. Osteopenia was diagnosed by measuring bone mineral density, which was calculated as the average pixel density in the midvertebral core at the 11th thoracic vertebra on the preoperative plain computed tomography image. We retrospectively investigated the relationship between preoperative osteopenia and severe postoperative complications (Clavien-Dindo classification ≥III). Univariate and multivariate analyses were performed to evaluate the risk factors for severe postoperative complications. Results: Twenty-three patients (22.3%) developed severe postoperative complications. The optimal cutoff value of bone mineral density for severe postoperative complications was 119.5 Hounsfield unit (HU) and 39 patients (37.9%) were diagnosed with osteopenia. The univariate analysis revealed that the American Society of Anesthesiologists Physical Status of ≥3 (P = .0084), hemoglobin levels (P = .0026), albumin levels (P < .001), sarcopenia (P = .015), and osteopenia (P < .001) were significantly associated with severe postoperative complications. The multivariate analysis showed that osteopenia (P = .014) was an independent risk factor for severe postoperative complications. Conclusion: Osteopenia may be a risk factor for severe postoperative complications in elderly patients after emergency gastrointestinal surgery.
RESUMO
The patient was an 81-year-old man who had received subtotal esophagectomy for esophageal cancer reconstructed by a gastric tube via a posterior mediastinal route. He presented to our emergency room with a complaint of epigastric pain and a small amount of hematemesis. Thoracoabdominal computed tomography showed that the reconstructed gastric tube was filled fluid and had irregular wall thickening. We suspected upper gastrointestinal bleeding, and we started to treat with administration of proton pump inhibitors (PPIs) since the anemia was mild and his vitals were stable. However, his anemia was rapidly progressed to Hb 6.0 with a large amount of old blood melena. The emergency gastroscopy showed an A2 stage ulcer with active oozing at middle esophagus reconstructed by a gastric tube. Therefore, we applied thrombin spray to treat the bleeding. Fortunately, his recovery was progressing nicely with medical treatments for a week. In this study, we experienced a case in which early administration of PPIs might be a key player to prevent his medical condition worsened further.
RESUMO
BACKGROUND: Suture granuloma with hydronephrosis after abdominal surgery is extremely rare. We herein report a successfully treated case of suture granuloma with hydronephrosis caused by ileostomy closure after rectal cancer surgery. CASE PRESENTATION: A 63-year-old male underwent laparoscopic low anterior resection with covering ileostomy. Two months after primary operation, ileostomy closure was performed with two layered hand-sewn suture (Albert-Lembert method) using absorbable suture. In that operation, marginal blood vessels in the mesentery were ligated with silk suture. The patient had remained in remission with no evidence of tumor recurrence, however, 2 years and 5 months after primary surgery, a contrast-enhanced computed tomography (CT) scan showed a mass-forming lesion on the right external iliac artery (43 × 26 mm) and hydronephrosis. Positron emission tomography/computed tomography (PET/CT) showed a mass-forming lesion without high accumulation, which obstructed the right ureter. Recurrence could not be ruled out due to the rapid appearance of tumor and hydronephrosis in the short-term period. Thus, the patient underwent laparotomy. The tumor located in the mesentery near the anastomosis of ileostomy closure and it was strongly adherent to the retroperitoneum, which obstructed the right ureter. The adhesion between the tumor and ureter was carefully dissected and tumor resection with partial small bowel resection was then performed with preservation of the ureter using ureteral stents. Pathological examination of the tumor revealed fibrous proliferation of foreign body granuloma. In the resected tumor, sutures with foreign giant cells were found. Therefore, we diagnosed the tumor as silk suture granuloma, which was caused by the silk suture used to ligate blood vessels of the mesentery at the ileostomy closure. The patient remained well with no evidence of tumor recurrence as 5 years after the primary operation of rectal cancer. CONCLUSIONS: Suture granuloma is a rare surgery-related complication in the postoperative surveillance of patients with colorectal cancer. If suture granuloma mimicking local recurrence is a differential diagnosis, it would be important to consider to avoid unnecessary extended resection.
RESUMO
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.
