Although the optimal treatment of AL is unknown, surgical resection with negative margins is the mainstay of management. We describe the case of a 72-year-old woman with metastatic rectal leiomyosarcoma, who initially presented with blood per rectum and worsening constipation. She was found to have a 7 × 7.3 cm mass prolapsing through the anal canal into the perineum without extraluminal extension or pathologic lymph nodes on MRI, with pathology consistent with sarcomatoid carcinoma. Transanal R0 resection was performed. Pathology showed a 6 cm high grade sarcoma consistent with leiomyosarcoma and negative margins. Two years post-resection, the patient was found to have a metastatic flank lesion, for which she underwent surgery. If accessible transanally, radical resection of AL is a valuable approach to treatment. Evidence regarding the best adjuvant treatment strategy is lacking and should be evaluated on a case-by-case basis.

The objective of this study is to evaluate two different operative interventions for short-term outcomes. The short-term outcomes include the conversion rate to open operation, intraoperative bleeding, operation time, length of hospital stay, number of lymph nodes harvested, peri-operative complications, and clear pathological resection margins. A search of MEDLINE at EBSCOhost, EMBASE, and Cochrane Library for articles from 1991 to 2020 was performed to identify randomized controlled trial studies that compared the clinical or oncologic outcomes of RAS and LAS. A meta-analysis was performed using the Review Manager (RevMan5.3) software. The data used were mean differences and odds ratios for continuous and dichotomous variables, respectively. Fixed-effects or random-effects models were adopted according to heterogeneity. Ten randomized controlled trial studies were included in the meta-analysis; 687 patients underwent RAS and 794 patients underwent LAS. The results revealed that conversion rates [relative risk (RR) =0.36, 95% confidence index (CI) =0.23–0.55, P < 0.00001], estimated blood losses [mean deviation (MD) = -15.01, 95% CI = -23.93–6.08, P = 0.0010], length of hospital stay (MD = -0.78, 95% CI = -1.11–0.46, P < 0.00001), and complications [odds ratio (OR) =1.04, 95% CI = 0.73–1.48, P = 0.97] were significantly reduced following RAS compared to that with LAS. There were no significant differences in operation time (MD = 0.61, 95% CI = -3.48–4.71, P = 0.77), number of lymph nodes harvested (MD = -0.08, 95% CI = -1.03–0.88, P = 0.87), and circumferential resection margin non-involvement (OR = 1.40, 95% CI = 0.88–2.25, P = 0.16) between the two techniques. The meta-analysis favored the robot-assisted technique. RAS is a promising technique and is a safe and effective alternative to LAS for colorectal surgery. The advantages of RAS include lower conversion rates, shorter hospital stay, and less intraoperative bleeding and complications. Further studies are required to define the effects of RAS on quality of life and long-term oncologic outcomes.","PeriodicalId":90396,"journal":{"name":"World journal of colorectal surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46515740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effects on surgical complications and outcomes are not well understood. Objectives: We aimed to assess the impact of pre-operative Ustekinumab on post-operative complications in patients with Crohn's disease undergoing abdominal surgery and compare to anti-tumor necrosis factor inhibitors (Anti-TNFs). Design: Systematic review and meta-analysis. Patient and Methods: We searched Medline (Ovid), The Cochrane Library (Wiley), EMBASE (Elsevier), Web of Science (Thomson Reuters), and Scopus (Elsevier), and CINAHL Plus with Full Text (Ebsco) for studies reporting rates of post-operative complications in Ustekinumab treated patients with Crohn's disease. Main Outcome Measure: Surgical site complications (SSI) and overall infectious complications between patients exposed to Ustekinumab pre-operatively in comparison to patients exposed to anti-TNFs pre-operatively. Sample Size: 6 studies including 650 patients. Results: Four out of six studies reported data for post-operative infectious complications between Ustekinumab and anti-TNFs. Among a total of 107 patients who received Ustekinumab and 543 patients who received anti-TNFs, there was no significant difference between the two groups in terms of total infectious complications (RR 1.30, 95% CI 00.54-3.12; P = 0.55). Three studies, including 102 patients in the Ustekinumab group and 481 patients in the anti-TNF alpha group, reported surgical site infections. No significant difference was observed between the two groups (RR 0.75, 95% CI 0.36-1.58; P=0.45). Conclusion: Pre-operative Ustekinumab use was not associated with reduced post-operative complication rates as compared to anti-TNFs in patients with Crohn's disease undergoing abdominal surgery, but there was substantial heterogeneity between trials.

The effects of delaying endoscopies on IBD outcomes are currently unknown. Objectives: This study aimed to evaluate effects of delayed endoscopies on IBD patients. Design: Retrospective study. Patient and Methods: review of all IBD patients scheduled for routine endoscopy at Northwestern Memorial Hospital March 13, 2020 through May 31, 2020, during which all endoscopies were canceled due to COVID-19. Patients were divided between rescheduled on-time after delayed. Patient outcomes one year after cancellation were examined. Main Outcome Measure: hospital and emergency room admissions, surgery, and medication changes. Sample Size: 250 patients. Results: 100 patients were included in the delayed group and 150 in the on-time group, with mean ages of 47.5 and 42.8 years respectively. 59.2% had Crohn's disease (CD), 39.2% had Ulcerative Colitis (UC) and 1.2% had indeterminate colitis. Both groups had similar severity scores during the delay and 1 year post-endoscopy. There was no difference in the number of emergency room or hospital admissions during the delay or at one-year post-endoscopy. One-year post-endoscopy there were significantly more hospitalizations in the on-time group (n=14, 9.3%) compared to the delayed group (n=3, 3%), P=0.03.

All four peoples developed FG, and an emergency debridement was performed, resulting in exposure of the rectum.

However, the impact body mass index (BMI) has on surgical staging through nodal harvest is not entirely understood. Objective: To identify the association between BMI and nodal harvest during elective colon cancer surgeries Design: Retrospective cohort review from 2015 to 2019. Setting: The National Surgical Quality Improvement Program-targeted colectomy database. Materials and Methods: The cohort was selected based on the codes corresponding to elective colectomies for colon cancer. BMI was grouped into the five clinically relevant categories and dichotomized. Nodal harvest was dichotomized into <12 and ≥12 lymph nodes. Univariate and multivariate regression analysis. Sample Size: A total of 35,039 patients. Main Outcomes Measures: The main outcome was adequate lymph node harvest for each BMI group. Secondary outcomes included analysis in laterality of tumors, approach, extent of resection, and identification of risk factors for adequate harvest. Results: The median BMI was 29.02 kg/m2 (interquartile range = 24.37–32.44) with a median of 22 (15–27) lymph nodes harvested. The BMI groups with the highest adequate lymph nodes harvested were those ≤25 with 93.7% compared to 92.8% in BMI >25 (P = 0.002). Right colon cancers had a higher rate of achieving adequate harvest than left colon cancers (94.8% vs. 90.8%, respectively; P < 0.001). Right tumors had a higher rate of adequate harvest in the ≤25 group, this frequency decreases as BMI increases and is the opposite for left tumors (P < 0.001). Inadequate harvest was higher for the open approach (9.82%) than that for laparoscopic (6.12%) or robotic (6.6%) procedures (P ≤ 0.001). BMI of ≤25 was associated with a 13% increase in the likelihood of an adequate nodal harvest (odds ratio = 1.13, 95% confidence index = 1.02–1.26). Conclusion: This study found that lower BMI was associated with a higher probability of achieving adequate nodal harvest. This can increase awareness about the risk of incomplete harvest in overweight and obese patients.
