ABSTRACT
Background: Anastomotic leak (AL) after minimally invasive esophagectomy (MIE) is a well-described source of morbidity for patients undergoing surgical treatment of esophageal neoplasm. With improved early recognition and endoscopic management techniques, the long-term impact remains unclear. Method(s): A retrospective review was conducted of patients who underwent MIE for esophageal neoplasm between January 2015 and June 2021 at a single institution. Cohorts were stratified by development of AL and subsequent management. Baseline demographics, perioperative data, and post-operative outcomes were examined. Result(s): During this period, 172 MIEs were performed, with 35 of 172 (20.3%) complicated by an AL. Perioperative factors independently associated with AL were post-operative blood transfusion (leak rate 52.9% versus 16.8%;p = 0.0017), incompleteness of anastomotic rings (75.0% vs 19.1%;p = 0.027), and receiving neoadjuvant therapy (18.5% vs 30.8%;p < 0.0001). Inferior short-term outcomes associated with AL included number of esophageal dilations in the first post-operative year (1.40 vs 0.46, p = 0.0397), discharge disposition to a location other than home (22.9% vs 8.8%, p = 0.012), length of hospital stay (17.7 days vs 9.6 days;p = 0.002), and time until jejunostomy tube removal (134 days vs 79 days;p = 0.0023). There was no significant difference in overall survival between patients with or without an AL at 1 year (79% vs 83%) or 5 years (50% vs 47%) (overall log rank p = 0.758). Conclusion(s): In this large single-center series of MIEs, AL was associated with inferior short-term outcomes including hospital length of stay, discharge disposition other than to home, and need for additional endoscopic procedures, without an accompanying impact on 1-year or 5-year survival. Key message: In this large, single-center series of minimally invasive esophagectomies, anastomotic leak was associated with worse short-term outcomes including hospital length of stay, discharge disposition other than to home, and need for additional endoscopic procedures, but was not associated with worse long-term survival. The significant association between neoadjuvant therapy and decreased leak rates is difficult to interpret, given the potential for confounding factors, thus careful attention to modifiable pre- and peri-operative patient factors associated with anastomotic leak is warranted.Copyright © 2022 The Authors
ABSTRACT
OBJECTIVE OF THE STUDY: In esophageal surgery, anastomotic leak (AL) remains one of the most severe and critical adverse events after oncological esophagectomy. Endoscopic vacuum therapy (EVT) can be used to treat AL; however, in the current literature, treatment outcomes and reports on how to use this novel technique are scarce. The aim of this study was to evaluate the outcomes of patients with an AL after IL RAMIE and to determine whether using EVT as an treatment option is safe and feasible. MATERIAL AND METHODS: This study includes all patients who developed an Esophagectomy Complications Consensus Group (ECCG) type II AL after IL RAMIE at our center between April 2017 and December 2021. The analysis focuses on time to EVT, duration of EVT, and follow up treatments for these patients. RESULTS: A total of 157 patients underwent an IL RAMIE at our hospital. 21 patients of these (13.4%) developed an ECCG type II AL. One patient died of unrelated Covid-19 pneumonia and was excluded from the study cohort. The mean duration of EVT was 12 days (range 4-28 days), with a mean of two sponge changes (range 0-5 changes). AL was diagnosed at a mean of 8 days post-surgery (range 2-16 days). Closure of the AL with EVT was successful in 15 out of 20 patients (75%). Placement of a SEMS (Self-expandlable metallic stent) after EVT was performed in four patients due to persisting AL. Overall success rate of anastomotic sealing independently of the treatment modality was achieved in 19 out of 20 Patients (95%). No severe EVT-related adverse events occurred. CONCLUSION: This study shows that EVT can be a safe and effective endoscopic treatment option for ECCG type II AL.
ABSTRACT
Background: The 2019 novel coronavirus (COVID-19) global pandemic has greatly changed the mode of hospital admissions. This study summarized and analyzed the incidence of severe diarrhea and anastomotic leakage during different periods for colorectal cancer surgery. Methods: From January 2017 to September 2020, 2,619 colorectal operations were performed in Peking Union Medical College Hospital. In contrast with previous years, enhanced hand hygiene training, more frequent ventilation of the wards, and separate bed treatments for patients were implemented in 2020. Data on incidence of severe diarrhea and anastomotic leakage were retrieved and collected. Results: The number of cases of severe diarrhea after colorectal surgery was 32 (4.60%), 24 (3.33%), 32 (3.83%), and 11 (2.99%) in 2017, 2018, 2019, and 2020 respectively, while the incidence of anastomotic leakage was 3.30% (23/696), 3.75% (27/720), 2.87% (24/835), and 2.17% (8/368), respectively. There was no significant difference in the incidence of postoperative severe diarrhea or anastomotic leakage across the various years. Conclusions: The number of colorectal surgeries in 2020 was significantly decreased due to the COVID-19 pandemic. Among the different years, no difference was observed regarding the incidence of postoperative flora disorder or anastomosis leakage. Enhanced hygiene measures during the COVID-19 epidemic partially contributed to the decrease of severe diarrhea and anastomotic leakage.
ABSTRACT
Cecal volvulus is an uncommon cause of acute intestinal obstruction accounting for around 10% of intestinal volvuli. There are three main variants of cecal volvuli including the axial, loop, and bascule types. Diagnosis is confirmed via a computed tomography scan and surgery is the mainstay treatment due to a high risk of morbidity and mortality. Here we report a rare presentation of cecal volvulus in a COVID-19 positive patient that was complicated by an anastomotic leak.
ABSTRACT
AIM: The objective of this systematic review was to investigate the outcomes of ileorectal anastomosis (IRA) in Crohn's disease and to clarify whether there are any time-related trends in outcome measures. The primary outcomes are risk of anastomotic leakage, death, clinical recurrence and subsequent diverting or permanent stoma and/or proctectomy. Secondary end-points are quality of life and functional outcome. METHODS: Systematic searches were conducted using the Cochrane Library, Embase and MEDLINE. The complete search strategy is uploaded online at http://www.crd.york.ac.uk/prospero/. Human studies in English with over five subjects were included and no limit was set regarding the date of publication. All relevant studies were screened by two reviewers. The web-based software platform www.covidence.org was used for primary screening of the title, abstract, full-text review and data extraction. RESULTS: The search identified 2231 unique articles. After the screening process, 37 remained. Key results were an overall anastomotic leak rate of 6.4%; cumulative rates of clinical recurrence of 43% and 67% at 5 and 10 years, respectively; an overall rate of proctectomy of 18.9%; and subsequent ileostomy required in 18.8%. Only one study presented useful data on quality of life. Recurrence rates remained stable over time. A small decline in the anastomotic leak rate was found. CONCLUSIONS: Only minor improvements in the outcomes of IRA in patients with Crohn´s disease have occurred during the past 50 years regarding anastomotic leakage and recurrence, except for a slight increase in the rate of a functioning IRA. These results call for implementation guidelines in patient selection for IRA and postoperative medical treatment and follow-up.
