Project description:The most common long-term complication post esophagectomy implicating the esophagogastric anastomosis is stricture-induced stenosis leading to late postoperative dysphagia. Herein, we present a case of a male patient readmitted to our Upper Gastrointestinal Department due to a food bolus obstruction through an anastomotic epithelial band arisen from a prior esophagogastric anastomosis performed 5 months earlier. A band transection in between two hemostatic clips placed on both sides of the band, followed by a release and fragmentation of the foreign body into several pieces led to its final transoral removal endoscopically. The patient experienced a direct resolution of his dysphagia and discharged on the same day. At 6 months follow-up, he remains symptom-free. In conclusion, endoscopic state-of-the-art techniques when combined with standard hemostatic surgical principles in a minimally invasive manner are excellent tools for the management of post-esophagectomy syndromes.

Project description:Background Recently, endoscopic vacuum therapy (EVT) was introduced as treatment for anastomotic leakage after upper gastrointestinal (GI) surgery. The aim of this study was to describe the initial experience with EVT for anastomotic leakage after upper GI surgery in a tertiary referral center.Methods Patients treated with EVT for anastomotic leakage after upper GI surgery were included retrospectively (January 2018-June 2021) and prospectively (June 2021-October 2021). The primary end point was the EVT success rate. Secondary end points included mortality and adverse events.Results 38 patients were included (31 men; mean age 66 years): 27 had undergone an esophagectomy with gastric conduit reconstruction and 11 a total gastrectomy with esophagojejunal anastomosis. EVT was successful in 28 patients (74 %, 95 %CI 57 %-87 %). In 10 patients, EVT failed: deceased owing to radiation pneumonitis (n = 1), EVT-associated complications (n = 2), and defect closure not achieved (n = 7). Mean duration of successful EVT was 33 days, with a median of six EVT-related endoscopies. Median hospital stay was 45 days.Conclusion This initial experience with EVT for anastomotic leakage after upper GI surgery demonstrated a success rate of 74 %. EVT is a promising therapy that could prevent further major surgery. More experience with the technique and its indications will likely improve success rates in the future.

Project description:BackgroundThe optimal target of endoscopic dilation of postsurgical esophageal strictures is unknown. Our aim was to compare the dilation-free period of patients who underwent dilation up to 16 mm with patients who were dilated up to 17 or 18 mm.MethodsWe retrospectively analyzed adult patients who received bougie/balloon dilation for a benign anastomotic stricture after esophagectomy. An anastomotic stricture was defined as dysphagia in combination with a luminal diameter of ≤13 mm at endoscopy. We analyzed the dilation-free period using Kaplan-Meier and multivariable Cox regression analysis.ResultsEighty-eight patients were dilated up to a maximum diameter of 16 mm and 91 patients to a diameter >16 mm. The stricture recurrence rate was 79.5 % in the 16 mm group and 68.1 % in the >16 mm group (p = 0.083). The overall dilation-free period had a median of 41.5 (range 8-3233) days and 92 (range 17-1745) days, respectively (p < 0.001). For patients who developed a stricture recurrence, the median dilation-free period was 28 (range 8-487) days and 63 (range 17-1013) days, respectively (p = 0.001). Cox regression analysis showed a reduced risk of stricture recurrence for patients who were dilated up to >16 mm: crude hazard ratio (HR) 0.57 (95 % confidence interval (CI) 0.41-0.81) and adjusted HR 0.48 (95 % CI 0.33-0.70).ConclusionsEndoscopic dilation over 16 mm resulted in a significant prolongation of the dilation-free period in comparison with dilation up to 16 mm in patients with benign anastomotic strictures after esophagectomy.

Project description:BackgroundRadiation-induced colorectal fibrosis (RICF) is a common pathological alteration among patients with rectal cancer undergoing neoadjuvant chemoradiotherapy (nCRT). Anastomotic stenosis (AS) causes symptoms and negatively impacts patients' quality of life and long-term survival. In this study, we aimed to evaluate the fibrosis signature of RICF and develop a nomogram to predict the risk of AS in patients with rectal cancer undergoing nCRT.MethodsOverall, 335 pairs of proximal and distal margins were collected and randomly assigned at a 7:3 ratio to the training and testing cohorts. The RICF score was established to evaluate the fibrosis signature in the anastomotic margins. A nomogram based on the RICF score for AS was developed and evaluated by using the area under the curve, decision curve analysis, and the DeLong test.ResultsThe training cohort included 235 patients (161 males [68.51%]; mean age, 59.61 years) with an occurrence rate of AS of 17.4%, whereas the testing cohort included 100 patients (72 males [72.00%]; mean age, 57.17 years) with an occurrence rate of AS of 11%. The RICF total score of proximal and distal margins was significantly associated with AS (odds ratio, 3.064; 95% confidence interval [CI], 2.200-4.268; P < 0.001). Multivariable analysis revealed that the RICF total score, neoadjuvant radiotherapy, and surgical approach were independent predictors for AS. The nomogram demonstrated good discrimination in the training cohort (area under the receiver-operating characteristic curve, 0.876; 95% CI, 0.816-0.937), with a sensitivity of 68.3% (95% CI, 51.9%-81.9%) and a specificity of 85.5% (95% CI, 78.7%-89.3%). Similar results were observed in the testing cohort.ConclusionsThis study results suggest that the RICF total score of anastomotic margins is an independent predictor for AS. The prediction model developed based on the RICF total score may be useful for individualized AS risk prediction in patients with rectal cancer undergoing nCRT and sphincter-preserving surgery.

Project description:Complete prolapse of rectum (procedentia) is said to occur when the full circumference of the rectal wall is everted through the anus. Numerous techniques have been developed in order to treat procedentia, an uncommon pathology that is managed occasionally by the general surgeon. A simple, safe and effective procedure is recommended for surgeons who treat procedentia recti once in a while. We describe a simple rectopexy procedure which has been used effectively in 38 patients in the last 10 years. In this prospective study we evaluated the results which are comparable to other standard operative techniques in terms of morbidity, anatomic correction and bowel function. This technique is based on sound scientific principles in the aetiopathogenesis of rectal prolapse. This procedure obliterates the abnormally deep cul de sac of rectovesical pouch and supports the anterior rectal wall by suturing it to the bladder base to prevent initiation of sliding herniation of anterior rectal wall, which causes procedentia recti. Posterior dissection fibrosis fixes the posterior rectal wall to the sacrum after healing and restores the normal posterior curve of rectal canal and corrects the pathogenic straightening of rectum which promotes prolapse. Minimal mobilization of rectum is done and lateral ligaments are not dissected hence all attendant complications e.g. impotence, urinary incontinence, constipation etc are avoided. Simplicity, effectiveness, safety and non requirement of prosthetic material makes it an ideal operation suitable for a general surgeon working in the periphery.

Project description:BackgroundAnastomotic leakage (AL) and small bowel obstruction (SBO) are common complications after rectal cancer radical surgery (Dixon). Although the commonly used defunctioning stoma (DS) can reduce the incidence and harm of AL, it increases the probability of other adverse consequences, including SBO. Therefore, a safe and effective method for preventing the complications related to the radical surgery of rectal cancer is urgently needed. Previous studies have found that transanal drainage tube (TDT) can have a positive impact on the incidence of these two complications by draining gas and feces from the intestinal lumen, without causing other serious consequences. Therefore, this article further explores the clinical benefits that TDT can bring by analyzing the clinical data of postoperative patients with rectal cancer.MethodsThis study included 221 patients who underwent radical surgery (Dixon) for rectal cancer in Hubei Cancer Hospital from September 2020 to February 2023, determine whether it meets the inclusion criteria of this study based on preoperative examination, intraoperative exploration results, and treatment methods. DS was used in 70 patients and TDT in 88 patients during the surgery; meanwhile, no protective anastomotic measures were applied in 63 patients. Seventy patients subjected to DS were categorized as group 1, 88 patients subjected to TDT as group 2, and 63 patients with no protective measures for anastomosis as group 3. Through postoperative clinical manifestations, imaging examinations, and laboratory tests, a total of 18 cases of AL and 30 cases of SBO were identified in the three groups. The effectiveness of TDT and that of other surgical procedures in preventing complications, accelerating postoperative recovery, and reducing surgical costs were compared through univariate and multivariate analyses.ResultsThe clinical features of the three groups have baseline comparability. No statistically difference was noted in baseline characteristics between three groups (all P>0.05). The incidence of AL and SBO in group 1 are 7.1% and 27.1%, in group 2 are 3.4% and 4.5%, and in group 3 are 15.9% and 11.1%. Compared to patients in no protective anastomotic measures with TDT and DS, TDT has a lower incidence of postoperative AL (P<0.05) and SBO (P>0.05), and faster postoperative recovery (P<0.05). The cost of inpatient surgery is not significantly different (P>0.05). Although DS can reduce the incidence of AL to a certain extent (P>0.05), it significantly increased the incidence of SBO (P<0.05), delayed postoperative defecation time (P<0.05) and caused higher cost (P<0.001). Compared to DS, the incidence of AL in TDT is not significantly different (P>0.05), but the incidence of SBO is noticeably lower (P<0.001), with faster postoperative recovery and less cost (P<0.05).ConclusionsTDT is a safer, more effective, and more economical surgery for preventing postoperative complications.

Project description:BackgroundAnastomotic leakage remains one of the most common serious complications after rectal cancer surgery. How to predict its occurrence and prevent it remains largely elusive.ObjectiveThis study aimed to identify the risk factors of anastomotic leakage and construct a nomogram for predicting postoperative anastomotic leakage in patients with rectal cancer.MethodsThe data of 406 patients with rectal cancer after gastrointestinal surgery in the Third Affiliated Hospital of Sun Yat-sen University from January 2011 to May 2020 were collected (243 in the training set and 163 in the testing set). Logistic regression was applied to determine the risk factors of postoperative anastomotic leakage of rectal cancer, and a nomogram prediction model was thus established. Predictive performance of the nomogram was evaluated by C-index and area under the receiver-operating characteristic (ROC) curve.ResultsLogistic regression analysis showed that preoperative bowel obstruction (odds ratio [OR] = 12.846, 95% confidence interval CI [1.441-114.54], p = 0.022) and early first defecation after surgery (OR = 0.501, 95% CI [0.31-0.812], p = 0.005) were independent risk factors, which could be used to develop a nomogram to predict the occurrence of anastomotic leakage accurately. The evaluation of the prediction model shows that the C-index value of the model was 0.955, the area under the ROC curve (AUC) of the training set was 0.820, and the testing set was 0.747, whereas the optimal cut-off point based on the nomogram score was 174.6.ConclusionThis nomogram had a good prediction ability for postoperative anastomotic leakage in patients with rectal cancer. It can provide a reference for perioperative treatment and the selection of surgical methods to promote individualized and accurate treatment.

Project description:BackgroundLeakage of rectal anastomoses is one of the most important and feared complications in colorectal surgery. Apart from patient-specific risk factors, technical aspects may influence the occurrence of anastomotic complications. This study investigated whether using single-stapling techniques (SST) instead of the double-stapling technique (DST) for minimal-invasive rectal anastomosis is associated with a lower rate of anastomotic complications.MethodsA retrospective review of 272 patients who received a minimally invasive stapled rectal anastomosis (3-16 cm from the anal verge) at our institution from 2015 to 2020 was performed. In 131 patients, rectal anastomosis was created by SST (SST group), while 141 patients received a rectal anastomosis with crossing stapler lines (DST group). The impact of the anastomotic technique on patient outcomes was determined by uni- and multivariate analyses.ResultsOverall anastomotic leakage rate was 6%. Patients with SST anastomoses had a lower leakage rate than patients with DST anastomoses (3% vs. 9% in the DST group, p = 0.045). The rate of anastomotic stenosis was lower in the SST group than in the DST group (1% vs. 6%, p = 0.037). Overall morbidity and mortality did not differ between the two groups. Multivariate analysis showed that single-stapling techniques significantly reduce the risk of anastomotic leakage (OR 3.5 [1.0-11.5], p = 0.043).ConclusionThe use of SST for rectal anastomosis may help to reduce anastomotic complications. This finding should be confirmed by a randomized controlled trial.

Project description:BackgroundComplications after surgery for esophageal cancer are associated with significant resource utilization. The aim of this study was to analyze the economic burden of two frequently used endoscopic treatments for anastomotic leak management after esophageal surgery: Treatment with a Self-expanding Metal Stent (SEMS) and Endoscopic Vacuum Therapy (EVT).Materials and methodsBetween January 2012 and December 2016, we identified 60 German-Diagnosis Related Group (G-DRG) cases of patients who received a SEMS and / or EVT for esophageal anastomotic leaks. Direct costs per case were analyzed according to the Institute for Remuneration System in Hospitals (InEK) cost-accounting approach by comparing DRG payments on the case level, including all extra fees per DRG catalogue.ResultsIn total, 60 DRG cases were identified. Of these, 15 patients were excluded because they received a combination of SEMS and EVT. Another 6 cases could not be included due to incomplete DRG data. Finally, N = 39 DRG cases were analyzed from a profit-center perspective. A further analysis of the most frequent DRG code -G03- including InEK cost accounting, revealed almost twice the deficit for the EVT group (N = 13 cases, € - 9.282 per average case) compared to that for the SEMS group (N = 9 cases, € - 5.156 per average case).ConclusionEndoscopic treatments with SEMS and EVT for anastomotic leaks following oncological Ivor Lewis esophagectomies are not cost-efficient for German hospitals. Due to longer hospitalization and insufficient reimbursements, EVT is twice as costly as SEMS treatment. An adequate DRG cost compensation is needed for SEMS and EVT.
