Cyanoacrylate in Colorectal Surgery: Is It Safe?

Anastomotic leakage (AL) of a gastrointestinal (GI) anastomosis continues to be an important complication in GI surgery. Since its introduction more than 60 years ago, Cyanoacrylate (CA) has gained popularity in colorectal surgery to provide "prophylaxis" against AL. However, although in surgical practice it is increasingly used, evidence on humans is still lacking. The aim of this study is to analyze in humans the safety of CA to seal colorectal anastomosis. All consecutive patients from Jannuary 2022 through December 2022 who underwent minimally invasive colorectal surgery were retrospectively analyzed from a prospectively maintained database. Inclusion criteria were a histological diagnosis of cancer, a totally minimally invasive procedure, and the absence of intraoperative complications. 103 patients were included in the study; N-butyl cyanoacrylate with metacryloxisulfolane (Glubran 2®) was used to seal colorectal anastomosis, no adverse reactions to CA or postoperative complications related to inflammation and adhesions occurred; and only one case of AL (0.9%) was recorded. We can consider this study an important proof of concept on the safety of CA to seal colorectal anastomosis. It opens the possibility of starting prospective and comparative studies in humans to evaluate the effectiveness of CA in preventing colorectal AL.

Redo laparoscopic colorectal resection: a retrospective analysis with propensity score matching

PURPOSE

Reports of redo laparoscopic colorectal resection (Re-LCRR) are scarce. In order to evaluate the safety and short-term outcomes of Re-LCRR, we performed a matched case-control analysis of patients who underwent this procedure for colorectal cancer.

METHOD

This was a retrospective, monocentric study that included patients who underwent Re-LCRR for colorectal cancer between January 2011 and December 2019 at our institution. The patients were compared to a 2:1 matched sample. Matching was conducted based on age, sex, BMI, surgical procedure, and clinical stage.

RESULT

Twenty-nine patients underwent Re-LCRR (RCRR group) and were compared to 58 patients selected by matching who underwent LCRR as primary resection (PCRR group). The median of age of the 29 patients of RCRR group was 75 (IQR 56-81) years and the RCRR group included 14 males. The median operative time of the RCRR group was 167 (IQR 126-232) minutes, and the median intraoperative blood loss was 5 (IQR 2-35) ml. In the RCRR group, there were no cases that required conversion to laparotomy. The short-term outcomes of the two groups did not differ to a statistical extent with respect to operative time (p = 0.415), intraoperative blood loss (p = 0.971), rate of conversion to laparotomy (p = 0.477), comorbidity (p = 0.215), and postoperative hospital stay (p = 0.809). No patients in either group experienced postoperative anastomotic leakage or required re-operation due to postoperative complications, and there was no procedure-related death. However, in terms of oncological factors, although there was no difference in the number of cases with a positive radical margin between the two groups (p = 1.000), the number of harvested lymph nodes in the RCRR group was significantly lower than that in the PCRR group (p = 0.015) and the RCRR group included 10 cases with less than 12 harvested lymph nodes.

CONCLUSION

Re-LCRR is associated with good short-term results and can be safely performed; however, the number of harvested lymph nodes is significantly reduced in comparison to primary resection cases, and further studies are needed to evaluate its long-term prognosis.

Perioperative intravenous dexamethasone for patients undergoing colorectal surgery: a systematic review and meta-analysis

PURPOSE

Dexamethasone is a glucocorticoid that is often administered intraoperatively as prophylaxis for postoperative nausea and vomiting (PONV). Several randomized controlled trials (RCTs) have examined its use in colorectal surgery. This systematic review aims to assess the postoperative impacts of dexamethasone use in colorectal surgery.

METHODS

MEDLINE, Embase, and CENTRAL were searched from database inception to January 2023. Articles were included if they compared perioperative intravenous dexamethasone to a control group in patients undergoing elective colorectal surgery in terms of postoperative morbidity. The primary outcomes were prolonged postoperative ileus (PPOI) and PONV. Secondary outcomes included postoperative infectious morbidity and return of bowel function. A pair-wise meta-analysis and GRADE assessment of the quality of evidence were performed.

RESULTS

After reviewing 3476 relevant citations, seven articles (five RCTs, two retrospective cohorts) met the inclusion criteria. Overall, 1568 patients received perioperative dexamethasone and 1459 patients received a control. Patients receiving perioperative dexamethasone experienced significantly less PPOI based on moderate-quality evidence (three studies, OR 0.46, 95%CI 0.28-0.74, p < 0.01). Time to first flatus was significantly reduced with intravenous dexamethasone. There was no difference between groups in terms of PONV (four studies, OR 0.90, 95%CI 0.64-1.27, p = 0.55), postoperative morbidity (OR 0.93, 95%CI 0.63-1.39, p = 0.74), or rate of postoperative infectious complications (seven studies, OR 0.74, 95%CI 0.55-1.01, p = 0.06).

CONCLUSION

This review presents moderate-quality evidence that perioperative intravenous dexamethasone may reduce PPOI and enhance the return of bowel function following elective colorectal surgery. There was no significant observed effect on PONV or postoperative infectious complications.

The Effects of Preoperative Steroid Therapy on Perioperative Morbidity and Mortality After Adult Spinal Deformity Surgery

STUDY DESIGN

Retrospective cohort analysis.

OBJECTIVES

To identify the effects of preoperative steroid therapy on 30-day perioperative complications after adult spinal deformity (ASD) surgery.

SUMMARY OF BACKGROUND DATA

Chronic steroid therapy has demonstrated therapeutic effects in the treatment of various medical conditions but is also known to be associated with surgical complications. There remains a gap in the literature regarding the impact of chronic steroid therapy in predisposing patients to perioperative complications after elective surgery for ASD.

METHODS

We performed a retrospective analysis of data from the 2008-2015 American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. Patients were divided into two groups based on preoperative steroid therapy. Differences in baseline patient characteristics, comorbidities, and operative variables were assessed. Univariate analysis was performed to compare the incidence of perioperative complications. Multivariate stepwise logistic regression models were then used to adjust for baseline patient and operative variables in order to identify perioperative complications that were associated with preoperative steroid therapy.

RESULTS

We identified 7,936 patients who underwent surgery for ASD, of which 418 (5.3%) were on preoperative steroid therapy. Preoperative steroid therapy was an independent risk factor for four perioperative complications, including mortality (odds ratio [OR] 2.42, 95% confidence interval [CI] 1.30, 4.51; p = .005), wound dehiscence (OR 3.12, 95% CI 1.45, 6.70; p = .004), deep vein thrombosis (DVT) (OR 2.10, 95% CI 1.24, 3.55; p = .006), and blood transfusion (OR 1.34, 95% CI 1.08, 1.66; p < .007).

CONCLUSIONS

Patients on preoperative steroid therapy are at increased risk of 30-day mortality, wound dehiscence, DVT, and blood transfusion after surgery for ASD. An interdisciplinary approach to the perioperative management of steroid regimens is critical.

LEVEL OF EVIDENCE

Level III.

The Role of Temporary Fecal Diversion

The use of temporary fecal diversion is of great importance to tenuous anastomosis, immunosuppressed patient, or actively infected patient. Its use protects newly constructed intestinal anastomoses from being the culprit of pelvic sepsis or systemic illness. Thus, potential morbidity and mortality can be averted. However, its appropriate or optimal use is often debated. We herein discuss the evidence for when to best use a diverting stoma for colorectal, coloanal, and ileoanal anastomoses. We also discuss the importance of considering a temporary diverting stoma in the setting of high-dose immunosuppression (e.g., transplant patients or inflammatory bowel disease), active infection, or upon creation of ileal pouch-anal anastomosis. Lastly, we discuss the advantages and disadvantages of a loop ileostomy versus colostomy for temporary diversion of fecal contents.

Preadmission glucocorticoid use and anastomotic leakage after colon and rectal cancer resections: a Danish cohort study

OBJECTIVE

To examine whether preadmission glucocorticoid use increases the risk of anastomotic leakage after colon and rectal cancer resections.

DESIGN

A population-based cohort study.

SETTING

Denmark (2001-2011).

PARTICIPANTS

We identified patients who had undergone a primary anastomosis after a colorectal cancer resection by linking medical registries. Participants who filled their most recent glucocorticoid prescription ≤90, 91-365 and >365 days before their surgery date were categorised as current, recent and former users, respectively.

MAIN OUTCOME MEASURES

We calculated 30-day absolute risk of anastomotic leakage and computed ORs using logistic regression models with adjustment for potential confounders.

RESULTS

Of the 18,190 patients with colon cancer, anastomotic leakage occurred in 1184 (6.5%). Glucocorticoid use overall was not associated with an increased risk of leakage (6.4% vs 6.9% among never-users; OR 1.05; 95% CI 0.89 to 1.23). Categories of oral, inhaled or intestinal-acting glucocorticoids did not greatly affect risk of leakage. Anastomotic leakage occurred in 695 (13.2%) of 5284 patients with rectal cancer. Glucocorticoid use overall slightly increased risk of leakage (14.6% vs 12.8% among never-users; OR 1.36, 95% CI 1.08 to 1.72). Results did not differ significantly within glucocorticoid categories.

CONCLUSIONS

Preadmission glucocorticoids modestly increased the risk of anastomotic leakage mainly after rectal cancer resection. However, absolute risk differences were small and the clinical impact of glucocorticoid use may therefore be limited.

Systematic review of preoperative, intraoperative and postoperative risk factors for colorectal anastomotic leaks

BACKGROUND

Anastomotic leak (AL) represents a dreaded complication following colorectal surgery, with a prevalence of 1-19 per cent. There remains a lack of consensus regarding factors that may predispose to AL and the relative risks associated with them. The objective was to perform a systematic review of the literature, focusing on the role of preoperative, intraoperative and postoperative factors in the development of colorectal ALs.

METHODS

A systematic review was performed to identify adjustable and non-adjustable preoperative, intraoperative and postoperative factors in the pathogenesis of AL. Additionally, a severity grading system was proposed to guide treatment.

RESULTS

Of 1707 papers screened, 451 fulfilled the criteria for inclusion in the review. Significant preoperative risk factors were: male sex, American Society of Anesthesiologists fitness grade above II, renal disease, co-morbidity and history of radiotherapy. Tumour-related factors were: distal site, size larger than 3 cm, advanced stage, emergency surgery and metastatic disease. Adjustable risk factors were: smoking, obesity, poor nutrition, alcohol excess, immunosuppressants and bevacizumab. Intraoperative risk factors were: blood loss/transfusion and duration of surgery more than 4 h. Stomas lessen the consequences but not the prevalence of AL. In the postoperative period, CT is the most commonly used imaging tool, with or without rectal contrast, and a C-reactive protein level exceeding 150 mg/l on day 3-5 is the most sensitive biochemical marker. A five-level classification system for AL severity and appropriate management is presented.

CONCLUSION

Specific risk factors and their potential correction or indications for stoma were identified. An AL severity score is proposed to aid clinical decision-making.

Treatment with corticosteroids and the risk of anastomotic leakage following lower gastrointestinal surgery: a literature survey

AIM

Background Anastomotic leakage is a serious complication in colorectal surgery. Treatment with corticosteroids is known to impair wound healing but their effect on the healing of a colorectal anastomosis remains unclear, and studies have reported conflicting results. Objective The aim of this study was to evaluate the current evidence regarding the effect of corticosteroids on the risk of anastomotic leakage following colorectal surgery.

METHOD

Search strategy A systematic review was conducted following a search of PubMed and Embase. Selection criteria Inclusion criteria were studies published in English and involving humans. A minimum cohort of 50 patients was required and anastomoses involving the ileum, colon and rectum were included. Studies that investigated corticosteroids as a risk factor for anastomotic leakage were included regardless of the duration and the dose of corticosteroids. Data Collection and analysis A comparison was conducted between anastomotic leakage in noncorticosteroid- and corticosteroid-treated patients. The main outcome measure was the risk of anastomotic leakage.

RESULTS

Twelve studies with a total of 9564 patients were included in the review. In total, 1034 patients received corticosteroids in the preoperative period, and 344 patients were diagnosed with anastomotic leakage, 70 of whom had received corticosteroids. Six of the 12 studies showed an increased risk for anastomotic leakage in the corticosteroid group. Overall, the anastomotic leakage rate was 6.77% (95% CI: 5.48-9.06) in the corticosteroid group and 3.26% (95% CI: 2.94-3.58) in the noncorticosteroid group.

CONCLUSION

Caution should be shown in patients scheduled for lower gastrointestinal surgery with anastomosis.

Pre-admission use of glucocorticoids and 30-day mortality following colorectal cancer surgery: a population-based Danish cohort study

BACKGROUND

Previous studies indicate that pre-admission glucocorticoids increase the risk of perioperative complications.

AIM

To examine whether pre-admission use of glucocorticoids affects 30-day mortality after colorectal cancer (CRC) surgery.

METHODS

We conducted a nationwide population-based cohort study by linking Danish medical registries. All residents in Denmark who underwent CRC surgery from 2001 to 2011 were included. We characterised subjects who filled their most recent glucocorticoid prescription ≤90, 91-365 and >365 days before their surgery date as prevalent, recent and former users, respectively. Prevalent users were subgrouped into new (first-ever prescription ≤90 days before surgery date) and continuing users. We estimated 30-day cumulative mortality by the Kaplan-Meier method and corresponding mortality rate ratios (MRRs) using Cox proportional hazard regression, adjusting for potential confounders.

RESULTS

Of the 34 641 CRC patients included, 3966 (11.5%) had filled one or more prescriptions of glucocorticoids within the year before the surgery date. Thirty-day mortality among prevalent users of oral glucocorticoids was 15.0% vs. 7.3% among non-users [MRR = 1.28; 95% confidence interval (CI): 1.03, 1.58]. Among new users, the 30-day mortality was 17.8% (MRR = 1.92; 95% CI: 1.30, 2.83) while it was 14.2% among continuing users (MRR = 1.13; 95% CI: 0.88, 1.44). No associations were found for recent or former use of oral glucocorticoids nor for use of inhaled, intestinal-acting, and mixed glucocorticoids.

CONCLUSIONS

Prevalent use, particulary new use, of oral glucocorticoids was associated with markedly increased 30-day mortality after colorectal cancer surgery compared to patients not exposed to any glucocorticoids.

Conservative treatment of early postoperative small bowel obstruction with obliterative peritonitis

AIM: To investigate the effect of somatostatin and dexamethasone on early postoperative small bowel obstruction with obliterative peritonitis (EPSBO-OP).

METHODS: This prospective randomized study included 70 patients diagnosed with EPSBO-OP from June 2002 to January 2009. Patients were randomized into two groups: a control group received total parenteral nutrition and nasogastric (NG) tube feeding; and an intervention group received, in addition, somatostatin and dexamethasone treatment. The primary endpoints were time to resolution of bowel obstruction and length of hospital stay, and the secondary endpoints were daily NG output and NG feeding duration, treatment-related complications, postoperative obstruction relapse, and patient satisfaction.

RESULTS: Thirty-six patients were allocated to the intervention group and 34 to the control group. No patient needed to undergo surgery. Patients in the intervention group had an earlier resolution of bowel obstruction (22.4 ± 9.1 vs 29.9 ± 10.1 d, P = 0.002). Lower daily NG output (583 ± 208 vs 922 ± 399 mL/d, P < 0.001), shorter duration of NG tube use (16.7 ± 8.8 vs 27.7 ± 9.9 d, P < 0.001), and shorter length of hospital stay (25.8 vs 34.9 d, P = 0.001) were observed in the intervention group. The rate of treatment-related complications (P = 0.770) and relapse of obstruction (P = 0.357) were comparable between the two groups. There were no significant differences in postoperative satisfaction at 1, 2 and 3 years between the two groups.

CONCLUSION: Somatostatin and dexamethasone for EPSBO-OP promote resolution of obstruction and shorten hospital stay, and are safe for symptom control without increasing obstruction relapse.

Identification of risk factors for esophagojejunal anastomotic leakage after gastric surgery

BACKGROUND

Despite the development of the surgical technique and improvements in perioperative management, anastomotic leakage still occurs at esophagojejunal anastomoses after total or proximal gastrectomy. Anastomotic leakage is one of the major complications of concern, chiefly because it can lead to death. The objective of the present study was to identify the risk factors for esophagojejunal anastomotic leakage.

METHODS

The study was based on retrospective analysis of the data of a total of 1,640 consecutive patients who underwent total, proximal, or completion gastrectomy, including esophagojejunal anastomosis, between 1999 and 2008.

RESULTS

Thirty-five patients (2.1 %) developed anastomotic leakage. Univariate analysis revealed patient age, pulmonary insufficiency, lymph node dissection, combined resection of other organs, omental resection, operative time, blood loss, intraoperative blood transfusion, and postoperative creatinine level were the significant factors influencing anastomotic leakage. Multivariate analysis identified pulmonary insufficiency and the duration of the operation as the predictors of anastomotic leakage.

CONCLUSIONS

To avoid leakage, surgeons should take care in creating the anastomosis in gastrectomy patients, particularly in cases of poor pulmonary function or when the procedure requires a longer operation.

Human fibrinogen patches application reduces intra-abdominal infectious complications in pancreas transplant with enteric drainage

PURPOSE

The purpose of the study was to analyze the incidence of intra-abdominal infectious complications after the application of a fibrinogen sealant to the duodenojejunal anastomosis in simultaneous pancreas-kidney transplants (SPK) with enteric drainage.

METHODS

Results of 68 SPKs with enteric drainage were prospectively assessed. A fibrinogen and thrombin sheet was applied to the duodenojejunal anastomosis in 34 patients, who were compared to a control group of 34 patients. The incidence and severity of intra-abdominal infectious complications and the 1-year patient and grafts survival were analyzed.

RESULTS

Eighteen patients experienced intra-abdominal infectious complications. Grade 1a complications occurred in the study group, whereas surgery was required only in patients from the control group: complications grade 3a (15%) and complications grade 3b (18%) (p = 0.003 vs. study group, respectively). The overall rate of anastomotic leakage (complications grade 2b and 3b) was 10%, all of which occurred in the control group. The length of hospital stay was higher in the control group was 34.6 ± 11.3 days vs. 22.8 ± 11.1 days (p = 0.03). There were no significant differences in 1-year patient and graft survival between groups.

CONCLUSIONS

In our study, the application of fibrinogen and thrombin sheets was associated to a decrease in the number and severity of intra-abdominal infectious complications.

[Colectomy in paediatric patients with ulcerative colitis]

INTRODUCTION

There are not many studies published in the literature on failure of medical treatment in Ulcerative Colitis (UC) that leads to colectomy.

PATIENTS AND METHODS

Retrospective study of patients under 14 years diagnosed with UC from 1984 to 2009, who underwent colectomy due to lack of response to medical treatment. They are divided into urgent or elective surgery.

RESULTS

Colectomy performed in 14 paediatric patients (26.9% of total UC patients). Age at diagnosis 7.8±4.0 years, 8 of them younger than 10 years and 5 younger than 5 years. All cases diagnosed on patients less than 5 years of age required colectomy in the first 6 months after diagnosis. Elective colectomy was performed on 5/14 and urgent surgery in 9/14. The reported complications were divided into early (first 30 days after colectomy) and late. Pharmacological treatment in cases with urgent colectomy included methylprednisolone (100%), oral tacrolimus (55.5%), oral/intravenous cyclosporine (33.3%) and infliximab (33.3%). Cases of elective colectomy were all in the 1985-1998 period.

CONCLUSIONS

The influence of age is a key factor for prognosis. All patients less than 5 year-old ended up with colectomy. The main indication for urgent surgery was lack of response to treatment with intravenous steroids combined with a potent immunomodulator (tacrolimus, cyclosporine, infliximab). All cases of elective colectomy were performed before 1999, when second line medical treatment was very uncommon, making remission unlikely.

Predicting the risk of anastomotic leakage in left-sided colorectal surgery using a colon leakage score

BACKGROUND

Anastomotic leakage following colorectal surgery still occurs all too frequently, and this complication is difficult to predict. A nonfunctional stoma may reduce the risk of clinically relevant leaks but is overtreatment for most patients. More accurate assessments of the risk of anastomotic leakage would be very helpful in tailoring treatment in colorectal surgery. Therefore, a Colon Leakage Score (CLS) was developed and tested.

MATERIAL AND METHODS

The CLS was developed based on information from the literature and expert opinions. It was tested in a retrospective cohort of consecutive patients undergoing left-sided colorectal surgery with primary anastomosis in a teaching hospital in The Netherlands.

RESULTS

In the test cohort, 10 of 121 patients who were not treated with a nonfunctional stoma experienced anastomotic leakage. The mean CLS in the leakage group was 16 versus eight in the group that did not have a leak (P < 0.01). Using receiver-operating characteristics, the area under the curve (AUC) showed that the CLS was a good predictor (AUC = 0.95, CI 0.89-1.00) of anastomotic leakage. Furthermore, logistic regression analysis with CLS as a predictor for anastomotic leakage showed an odds ratio of 1.74 (95% CI 1.32-2.28, P < 0.01).

CONCLUSIONS

The CLS can predict the risk of anastomotic leakage following left-sided colorectal surgery. After further validation, this score may help the surgeon make a more individualized, safer decision regarding whether to perform an anastomosis or make a (nonfunctional) stoma.

Postoperative outcome of colectomy for pediatric patients with ulcerative colitis

BACKGROUND

Few studies have reported on the surgical outcomes of colectomy in pediatric patients with ulcerative colitis (UC).

PATIENTS AND METHODS

We conducted a retrospective chart review of all pediatric patients diagnosed with UC who underwent colectomy at UCSF between 1980 and 2005 to identify early (within 30 days) and later complications of surgery.

RESULTS

Complete medical records were available for 31 patients [12.4 +/- 3.3 (range 6-19) years] with UC who underwent colectomy at UCSF Children's Hospital. Total colectomy with ileal pouch anal anastomosis (IPAA) was performed in 21 of the 31 patients (12 without diverting ileostomy). Five of the 31 patients had an initial colectomy with IPAA and J-pouch performed later; 4 had an initial subtotal colectomy for urgent indications. Only one of 31 had IPAA with S-pouch. The median number of early postoperative complications was 1.0; 4 required additional surgery to treat complications. The most common early complications were small intestinal obstruction in 6 (19%) and wound infection in 4 (13%). Preoperative medications included corticosteroids in 25 (81%), 6-mercaptopurine/azathioprine in 10 (32%), and 5-aminosalicylates in 19 (61%). Medication exposure was not related to postoperative complications. Late complications included pouchitis in 12 (39%), anastomotic, anal, or rectal strictures in 5 (16%), and fistulas in 5 (16%); 1 (3%) was subsequently diagnosed as having Crohn disease.

CONCLUSIONS

Postcolectomy morbidity is common among pediatric patients with UC. Preoperative medications were not associated with postoperative complications. Investigations to determine preoperative factors affecting surgical outcomes and long-term satisfaction following this surgery in a large pediatric cohort are needed.

After-hours colorectal surgery: a risk factor for anastomotic leakage

PURPOSE

This study aims to increase knowledge of colorectal anastomotic leakage by performing an incidence study and risk factor analysis with new potential risk factors in a Dutch tertiary referral center.

METHODS

All patients whom received a primary colorectal anastomosis between 1997 and 2007 were selected by means of operation codes. Patient records were studied for population description and risk factor analysis.

RESULTS

In total 739 patients were included. Anastomotic leakage (AL) occurred in 64 (8.7%) patients of whom nine (14.1%) died. Median interval between operation and diagnosis was 8 days. The risk for AL was higher as the anastomoses were constructed more distally (p = 0.019). Univariate analysis showed duration of surgery (p = 0.038), BMI (p = 0.001), time of surgery (p = 0.029), prophylactic drainage (p = 0.006) and time under anesthesia (p = 0.012) to be associated to AL. Multivariate analysis showed BMI greater than 30 kg/m(2) (p = 0.006; OR 2.6 CI 1.3-5.2) and "after hours" construction of an anastomosis (p = 0.030; OR 2.2 CI 1.1-4.5) to be independent risk factors.

CONCLUSION

BMI greater than 30 kg/m(2) and "after hours" construction of an anastomosis were independent risk factors for colorectal anastomotic leakage.
