INTRODUCTION: Postoperative small bowel obstruction (SBO) is a major complication following colorectal cancer surgery, yet evidence-based prevention strategies remain unclear. We aimed to clarify site-specific risk factors for SBO and evaluate the effectiveness of laparoscopic surgery and adhesion prevention materials (APMs) in preventing SBO after colorectal cancer surgery. METHODS: This retrospective cohort study analyzed 5458 patients who underwent colorectal cancer surgery at 32 Japanese institutions between 2012 and 2014. The primary endpoint was the 5-year risk of SBO. We evaluated the effects of laparoscopic surgery, APM use, and stoma creation on SBO risk. Clinical variables included demographics, tumor site, operative approach, operative details, and postoperative complications. Hospital-level clustering was addressed using mixed-effects logistic regression. RESULTS: Overall SBO incidence was 5.2% (n = 283). Rectal cancer had the highest risk, whereas all colonic sites except the descending colon showed significantly lower odds. Laparoscopic surgery was associated with a 42% reduction in odds (OR 0.58; 95% CI 0.45-0.74; p < 0.001), with significant reductions in ascending (NNT = 22.2, p = 0.001) and sigmoid colon surgery (NNT = 30.2, p = 0.003). APMs showed no protective effect (OR 1.01; 95% CI 0.78-1.32; p = 0.94). Stoma creation significantly increased SBO risk (OR 1.84; 95% CI 1.35-2.51; p < 0.001). Secondary analysis identified reoperation and postoperative ileus as additional independent risk factors. DISCUSSION: Laparoscopic surgery was associated with reduced long-term SBO risk, with significant benefits in ascending and sigmoid colon surgery. APMs showed no measurable benefit. Stoma creation increased SBO risk, with no observed difference between ileostomy and colostomy.
ObjectiveTo systematically analyze the efficacy of ultrasound-guided mammotome minimally invasive surgery and traditional open surgery in the therapy of benign breast tumors.MethodsA computerized search retrieved original literature on the therapeutic effects of ultrasound-guided mammotome minimally invasive surgery and traditional open surgery for benign breast tumors from authoritative databases, including CNKI, Wanfang, VIP, Web of Science, PubMed, ScienceDirect, Cochrane Library, and Embase. The search covered from database inception to January 2024, using a strategy of subject terms combined with free terms. The retrieved literature was screened, data were extracted, and quality was evaluated. Meta-analysis was performed using RevMan 5.4 software.ResultsA total of 8 literatures were included in the study, and a total of 1909 patients with benign breast tumors were found from 2018 to 2023. The results of meta-analysis showed that the operation time [MD = -12.79, 95%CI (-14.04, -11.55), P < 0.00001], intraoperative blood loss [MD = -11.55, 95%CI (-14.74, -8.36), P < 0.00001], healing time [MD = -2.73, 95%CI (-4.03, -1.43), P < 0.00001] and complication rate [MD = 0.17, 95%CI (0.12, 0.26), P < 0.00001] was apparently different from traditional open surgery (P < 0.05).ConclusionUltrasound-guided mammotome minimally invasive surgery can effectively shorten the operation time of patients with benign breast tumors, reduce intraoperative blood loss, promote healing, and reduce the risk of complications. The effect is better than that of traditional open surgery.
BACKGROUND: Bladder drainage is systematically used in rectal cancer surgery in male patients, even in the era of enhanced recovery after surgery (ERAS). However, little data is available on risk factors for urinary tract infection (UTI). Identifying the risk factors associated with UTI within 4 days of male rectal cancer surgery in an ERAS program could support more individualized decision-making. METHODS: We used data from the GRECCAR 10 randomized clinical trial, a comparison of outcomes of transurethral catheterization (TUC) or suprapubic catheterization (SPC). 240 patients were randomized, 209 retained in the study (TUC n = 99; SPC n = 109). Univariate and multivariate logistic regression post-hoc study analyses were performed to assess association between potential predictive factors and UTI within 30 days after surgery. RESULTS: Out of 208 patients (median age 64.5 years), 19 (9.1%) had UTI, 26 (12.5%) had bacteriuria and 145 (69.7%) had pyuria. Univariate analysis identified age ≥ 65 years (OR = 3.08 [1.07-8.89]; p = 0.038), hypertension (OR = 3.65 [1.23-10.84]; p = 0.020) and ASA score ≥ 3 (OR = 4.15 [1.53-11.2]; p = 0.005) as risk factors for UTI until POD4. Multivariate analysis identified ASA score ≥ 3 with a risk of UTI. CONCLUSION: Regarding male rectal cancer surgery, our study shows that nearly 1 in 10 patients had UTI within 4 days. An ASA score ≥ 3 is an independent risk factor linked to UTI. Identifying this risk factor for UTI is necessary to advise patients, support a tailored decision-making process, and prevent these complications.
INTRODUCTION: The implementation of robotic surgery in public hospitals presents multiple logistical, educational, and organizational challenges. In the absence of unified guidelines, a national consensus is required to optimize its safe and efficient adoption. This study aimed to establish a set of consensus-based and measurable recommendations for the implementation of robotic surgery programs in hospitals within the Spanish National Health System, based on the experience of centres with established robotic programs and intended to serve as guidance for hospitals that are initiating or planning their implementation. METHODS: A national Delphi study was conducted with the participation of robotic surgery experts from 26 public hospitals. The expert panel was composed exclusively of digestive surgeons with experience in robotic surgery. Three iterative rounds of expert panel evaluation were conducted between March 2024 and March 2025. The questions were grouped into five thematic blocks. Consensus was defined as an agreement level of ≥66.7%. Kendall's W coefficient was used to assess concordance. RESULTS: High levels of consensus were achieved on key aspects related to infrastructure, structured training, cost evaluation, and quality assurance mechanisms. Areas of disagreement were also identified, such as the need for a dedicated anaesthesiologist, purchase of accessory instruments during the initial phase, and official accreditation pathways. CONCLUSIONS: This study provides a guideline for developing a national robotic surgery strategy focused on patient safety, program sustainability, and standardized training of surgical teams. These recommendations can guide hospitals at different stages of robotic technology adoption. Given that the consensus was reached from an exclusively surgical perspective, the recommendations focus on patient safety, program sustainability, and standardized training of the surgical team, and should be interpreted in an adaptable manner according to each centre's context, case volume, and available resources.
The supply of surgical services--a function of both the number of surgeons and the amount of surgery each performs--was extensively studied as a basis for new public policies in medical practice. The Report concludes that there is a surplus of physicians performing surgery and recommends restricting their number through more rigorous board certification and reducing the number of new entrants to specialized training. But the technological criteria advanced to assure "quality" are not based on adequate empirical evidence; and control by surgeons over their own numbers is likely to have uneven--and unfavorable--consequences for the public. The causes of surplus surgical capacity must be explained, and impediments to self-correction through competition in the "medical market" addressed in future policy.
There is considerable uncertainty about the effects of bypass surgery on the longevity of patients with coronary-artery disease and angina. The Cleveland Clinic has reported improved survival after surgical treatment; the Duke University study indicated improvement in a high-risk subgroup only. The Veterans Administration (V.A.) randomised study initially reported improved survival only for patients with significant left main artery (L.M.) disease. Further analysis of the V.A. study shows that survival in the high-risk subgroup was 87% for the surgically treated patients and 74% for those treated medically--a highly significant difference after four years of follow-up. However, exclusion of the L.M. group reduced the difference to a non-significant one of 84% versus 79%. For patients not in the high-risk subgroup, survival at four years (with L.M. excluded) was 93% for those treated surgically and 96% for those treated medically. For all patients the rates were 85% and 86%, respectively. These findings indicate that in the evaluation of the effects of bypass surgery on longevity the characteristics of the coronary-artery disease are critical.
A surgical technique to establish wide zones of attached mucosa was performed in 28 patients presenting with inadequate amounts of attached gingiva. The clinical results of the procedure were monitored over a period of 2 years. Biometric assessment of 112 mucogingival units immediately before and at 1, 3, 6, and 24 months after surgery revealed that the mean width of attached gingiva changed from 1.1 mm to 5.3 mm of attached tissue (gingiva plus vestibular mucosa). A surgically produced increase of 4.9 mm in width (P less than 0.001) and subsequent shrinkage of 0.7 mm or 14% (P less than 0.001) resulted in a total average gain of 4.2 mm of attached mucosa 2 years after surgery (P less than 0.001). A begin/end analysis of the coronal level of clinical periodontal attachment and the extent of gingival recession showed no clinically significant changes. The mean width of keratinized gingiva increased 0.8 mm during the 2-year postoperative period. The subperiosteal vestibule extension is recommended as an alternative to the free autogenous mucosa graft for establishing wide bands of attached mucosa in areas where loss of attached gingiva is associated with mechanical or microbial irritation of the marginal periodontium.
768 men aged under 65 with angina pectoris, at least 50% obstruction in two or more major vessels, and a left-ventricular ejection fraction greater than or equal to 0.5 took part in a prospective randomised trial of the effect of coronary-artery bypass on prognosis. 373 patients were alloted to medical and 395 to surgical treatment. There was no significant difference between the two groups in the distribution of variables recorded at the time of randomisation. 1. "surgical" patient was lost to follow-up. 26 "surgical" patients did not undergo surgery and 50 "medical" patients were operated on. All these 76 patients were retained in their original treatment groups for the analysis. At 2 years there was no significant difference in mortality between the two groups. A significant difference was, however, found in the subset of patients with three-vessel disease, survival being significantly better for surgical patients. Operative (in-hospital) mortality was 3.6% in all operated patients and 1.5% in the last third. On average, 1.9 grafts per patient were inserted in the two-vessel-disease subgroup and 2.4 grafts per patient in the three-vessel-disease subgroup. Graft-patency rate was 90% within 9 months and 77% between 9 and 18 months after surgery. Symptomatic improvement was significantly better and deterioration less in the surgical group.
BACKGROUND: While dexamethasone is proven to enhance single-shot erector spinae plane block (ESPB), its role as an adjuvant in continuous ESPB catheters is unclear. This randomised controlled trial evaluated whether adding dexamethasone to ropivacaine improves analgesia after video-assisted thoracoscopic surgery (VATS). METHODS: 85 patients undergoing VATS with continuous ESPB were randomised to receive postoperative infusion of either 0.2% ropivacaine(C-ESPB group) or ropivacaine with 10 mg dexamethasone(D + C-ESPB group). The primary outcome was resting pain visual analog scale (VAS)at 12 h postoperatively, while secondary outcomes included QoR-15 scores, tramadol consumption, time to first analgesic requirement, postoperative adverse events, 3-month incidence of chronic pain, catheter-related complications, pain intensity at other times, and hospital stay. RESULTS: The D + C-ESPB group had significantly lower resting pain at 12 h [2.56 (1.03) vs 3.24 (1.21), mean difference -0.680, p = 0.006]; and lower coughing pain at 12 h [4.60 (1.48) vs 5.69 (1.35), mean difference 1.086, p < 0.001], with analgesic superiority sustained through 72 h. Quality of Recovery-15 scores were higher at 12 h [124.70 (12.48) vs 117.26 (12.24); mean difference -7.436, p = 0.007] and 48 h [141.60 (5.51) vs 138.98 (6.64); mean difference -2.628, p = 0.050]; Total tramadol consumption over 72 h was markedly reduce [0 (0,100) vs 100 (75,100), z = -3.807, p < 0.001], and hospital stay was shorter [Mean (SD) 6.09 (1.34) d vs 6.93 (1.55)d, p < 0.001]. The intervention did not, however, alter the 3-month incidence of chronic postsurgical pain (31% vs 34%, p = 0.756). CONCLUSION: Dexamethasone significantly enhances the analgesic efficacy of continuous ESPB, improving early pain control, recovery quality, and opioid-sparing after VATS, but does not reduce the incidence of chronic persistent surgical pain.
Indications for the use of glucocorticoids in surgical stomatology are: 1. emergencies, 2. bullous and allergic diseases of the oral mucosa and therapy-resistant cases of chronic recurrent aphthae, erosive lichen planus and sialoses (for systemic therapy), 3. therapy-resistant temporomandibular complaints and hyperplastic tissue responses and, in combination with an antibiotic, diseases of the maxillary sinus (for local therapy). Preliminary clinical examination, case controls at short intervals, and circadian or alternating prescription will help to reduce undesirable side-effects. In patients receiving sustained glucocorticoid therapy, dental-surgical procedures require special consideration of the change in reactivity.
