P-OGC68 Prophylactic Endoluminal Vacuum Therapy (EVT) following oesophagectomy

Background Endoluminal vacuum therapy (EVT) is an emerging treatment strategy for the management of anastomotic leaks following oesophagectomy. However, patients are often critically unwell with mediastinitis and established sepsis by the time the leak is diagnosed. This results in a protracted recovery period regardless of the effectiveness of EVT in treating the leak. Prophylactic EVT to protect the anastomosis following oesophagectomy may reduce the incidence of anastomotic leak, and/or mediastinitis and sepsis if the anastomosis does fail. We report the outcomes of two patients considered high risk for anastomotic leak who were managed with prophylactic EVT following esophagectomy for cancer. Methods Two patients received prophylactic EVT following oesophagectomy between May and July 2021. The patients were considered high risk for anastomotic leak due to technical concerns with, or complications during, the operation. In both cases the oesophagogastric anastomosis (OGA) was fashioned with a circular stapler. The endoluminal vacuum device (EVD) was constructed using an 18F nasogastric tube and a piece of open cell foam, and placed intraluminally across the anastomosis under endoscopic guidance at the time of surgery. Continuous negative pressure (125mmHg) was applied. Information relating to treatment and outcome was recorded prospectively. Results Patient-1, a 72-year-old female, ASA 2, underwent minimally invasive oesophgectomy for an adenocarcinoma at the gastro-oesophageal junction. After creating the stapled OGA, inspection revealed the proximal (oesophageal) tissue doughnut was complete but attenuated. Patient 2, a 67-year-old male, ASA 3, underwent a hybrid Ivor Lewis oesophgectomy for a lower 1/3 oesophageal adenocarcinoma. Surgery was complicated by significant intra-abdominal bleeding requiring blood transfusion and pressor support. In both cases, endoscopic assessment of the anastomosis following removal of the prophylactic EVD was performed day seven post-operatively. The anastomoses were healthy with no evidence of a leak, dehiscence, or early stricture formation. Conclusions In this limited case series, prophylactic EVT of the OGA following oesophagectomy was delivered safely with no complications related to insertion of the EVD or delivery of EVT. This intervention should be considered in cases where the risk of anastomotic leak is high. An intraluminal EVD situated across the OGA may minimise the extent of extraluminal contamination, and the systemic consequences of sepsis associated with this, should an anastomotic breakdown occur. Further studies are required to determine the safety of prophylactic EVT following oesophagectomy, and whether this improves surgical outcomes by reducing the incidence and impact of anastomotic leaks.

Risk Factors for Reoperation Following Radical Gastrectomy in Gastric Cancer Patients

Background Reoperation due to elective surgery complications is very mentally, physically, and economically detrimental to patients. This study investigated the potential risk factors associated with early reoperation after radical gastrectomy in gastric cancer patients and included an in-depth analysis of these risk factors. Methods This retrospective study reviewed 1568 patients with gastric cancer. Grade 3 or greater complications were defined as severe. Any factors related to reoperation after radical gastrectomy were analyzed in patients with severe local complications. Results Among 1537 patients undergoing radical gastrectomy, 115 (7.5%) patients had severe postoperative complications, 98 (6.38%) of whom experienced severe local complications. The most common local complication was anastomotic leakage (31, 2.02%), followed by intra-abdominal abscess (30, 1.95%), pancreatic leakage (22, 1.43%), duodenal stump leakage (18, 1.17%), intra-abdominal bleeding (12, .78%), intraluminal bleeding (8, .52%), small bowel obstruction (5, .32%), and chyle leakage (3, .19%). Of these patients, 26 (1.69%) underwent reoperation, and 6 (.39%) died. In the univariate analysis of clinical factors related to reoperation, intra-abdominal bleeding and small bowel obstruction were risk factors for reoperation, and intra-abdominal bleeding (odds ratio [OR] = 9.57, confidence interval [CI] = 2.65-40.20, P < .001) and small bowel obstruction (OR = 19.14, CI = 2.60-390.13, P = .011) were independent risk factors associated with reoperation in the multivariate analysis. Conclusion Intra-abdominal bleeding and small bowel obstruction are independent risk factors for reoperation following radical gastrectomy. Patients with postoperative intra-abdominal bleeding and small bowel obstruction need to be warned about reoperation.

RESULTS OF ENDOSCOPIC DIAGNOSIS OF BLEEDING AFTER ABDOMINAL SURGICAL OPERATIONS

The aim of the study is to conduct a comparative analysis of the effectiveness of endovidiosurgical diagnosis techniques to detect gastrointestinal and intra-abdominal bleeding, which may occur after abdominal operations. Materials and methods. The main group included patients (n=408), whose condition was controlled by the endovideosurgical techniques. The control group included patients (n=102) who were controlled by using conventional surgical methods to correct bleeding that may occurred after similar surgical interventions. Gastrointestinal bleeding was observed in 323 patients, and intra-abdominal bleeding was observed in 85 patients. In all cases, endoscopic haemostasis was performed by clipping (n=57), submucosal infiltration (n=32), electrocoagulation (n=29), argon-plasma coagulation (n=74), and combined techniques (n=54). Results and discussion. 408 patients with clinical signs of bleeding in the early postoperative period were examined by endoscopic techniques. Patients with alarming clinical and laboratory findings underwent ultrasound examination, which revealed the presence of free fluid in one or more parts of the abdominal cavity. Laparoscopy was performed in the first hours of the postoperative period in 17 cases (n=17); on the first day of the postoperative period (n=36), on the second day (n=19), on the third (n=8), on the fifth (n=3), and on the sixth day (n=2). Complications were excluded in 7 (16.0%) patients, despite a decrease in blood pressure and haemoglobin levels. The volume of blood found in the abdominal cavity, including clots, ranged from 30 ml to 2000 ml. Signs of ongoing bleeding (the predominance of a large amount of liquid blood with a small number of clots) were found in 49 (57.6%) cases, and signs of arrested bleeding (the presence of a large number of clots with a small amount of liquid blood) was detected in 29 (34.1%) cases. Haemostasis was provided by electrocoagulation (n=35), clipping (n=15), suturing (n=12) and tamponade from a mini-laporatomic incision (n=9). Gastrointestinal bleeding was observed in 323 patients, and intra-abdominal bleeding in 85 patients. In 8.4% (n=27) of cases, the suspicious cases of postoperative complication were excluded by endoscopic examinations. In 91.6% (n=296) of clinical cases, early postoperative bleeding or signs of unstable haemostasis with the risk of repeated bleeding were confirmed. In cases of alarming clinical and laboratory findings indicating intra-abdominal bleeding, diagnostic laparoscopy enables to exclude complications in 16.0% of patients, despite a decrease in blood pressure and haemoglobin levels.

Bilateral ovarian apoplexy

If unilateral ovarian apoplexy is quite rare and accounts for 0.5-2% among intra-abdominal bleeding of genital origin (M. S. Malinovsky, I. S. Breido, O. I. Topchieva, D. A. Lemberg, A. A. Vasiliev and others), then bilateral ovarian bleeding from the ovary is extremely rare.

Effects of Different Recovery Positions on the Postpercutaneous Liver Biopsy Complications: A Metaanalysis

Objective: We aim to evaluate the effects of different recovery positions on the adverse events and the patient acceptability in those who underwent percutaneous liver biopsy (PLB).Methods: A literature search was conducted in the Cochrane Library, Embase, Scopus, PubMed, CNKI, Sinomed, and Wanfang databases. The time for the article extraction was until July 2020. The articles were screened by two independent researchers, together with the bias risk evaluation and data extraction. The RevMan 5.4 software was utilized for the metaanalysis.Results: Finally, two articles involving 180 subjects were eligible for this study. Metaanalysis showed that at T0, the alternation between right-side and combined position (CRP) would induce an elevation of post-PLB pain compared with the dorsal/supine position (SRP) [WMD = −2.00, 95% CI (−3.54, −0.47), p = 0.01]. There were no statistical differences in the postoperative pain among the CRP, SRP, and right-side position (RRP). The patient acceptability of SRP and RRP was higher than that of the CRP. Finally, two eligible studies were included, which showed no incidence of pneumothorax and abdominal bleeding.Conclusions: CRP would induce post-PLB pain at T0. SRP was the most acceptable position for the cases that underwent PLB. There were no statistical differences in the incidence of pneumothorax and abdominal bleeding.Systematic Review Registration:https://www.crd.york.ac.uk/PROSPERO, identifier: CRD42020196633.

To the diagnosis of intra-abdominal bleeding

K. Lange (Zentrlbl. F. Chir. 1929, No. 36) with unclear and severe cases of abdominal bleeding attaches great importance to the Klenkampff symptom: a pronounced sensitivity of the abdominal wall to percussion with almost or complete absence of tension of the abdominal wall.

Trauma-Induced Rupture of Liver Hydatid Cyst: A Rare Cause of Anaphylactic Shock

Hydatid disease is rare; nevertheless, several areas of the world are endemic. Lebanon is one of the endemic countries. This disease requires careful management, as its diagnosis is tough, and its complications are severe and can lead to sudden death. These complications include fistulas, infection, and rupture. Rupture of a hydatid cyst can mimic acute abdomen and show an array of nonspecific symptoms. It could be mistaken for hemorrhagic shock, trauma, or injury to an intra-abdominal organ. The diagnosis of ruptured hydatid cyst should be kept in mind in cattle-raising countries. We report the case of a polytrauma patient who was suspected to have severe intra-abdominal bleeding and hemorrhagic shock, but imaging and laparotomy showed the rupture of a liver hydatid cyst that drove the patient into anaphylactic shock. This article reviews similar cases in the literature and discusses the diagnostic tools, appropriate management, and expected complications.

Comparison of Different Surgical Methods for Necrotizing Pancreatitis: A Meta-Analysis

Purpose: To compare the effectiveness and safety of three methods of open necrosectomy, minimally invasive surgery and endoscopic step-up approach for necrotizing pancreatitis.Methods: We searched Pubmed, Embase, ScienceDirect, and CNKI full text database (CNKI) (to December 25, 2019). RCT, prospective cohort study (PCS), and retrospective cohort study (RCS) comparing the effectiveness and safety of any two of above-mentioned three methods were included.Results: There was no significant difference in major complications or death, and mortality between the minimally invasive surgery treatment group and the endoscopic step-up approach treatment group (RR = 1.66, 95%CI: 0.83–3.33, P = 0.15; RR = 1.05, 95%CI: 0.59–1.86, P = 0.87); the incidence rate of new-onset multiple organ failure, enterocutaneous fistula, pancreatic-cutaneous fistula, intra-abdominal bleeding, and endocrine pancreatic insufficiency in the endoscopic step-up approach treatment group was significantly lower than minimally invasive surgery group (RR = 2.65, 95%CI: 1.10–6.36, P = 0.03; RR = 6.63, 95%CI: 1.59–27.60, P = 0.009; RR = 7.73, 95%CI: 3.00–19.89, P &lt; 0.0001; RR = 1.91, 95%CI: 1.13–3.24, P = 0.02; RR = 1.83, 95%CI: 1.9–3.16, P = 0.02); hospital stay in the endoscopic step-up approach group was significantly shorter than minimally invasive surgical treatment group (MD = 11.26, 95%CI: 5.46–17.05, P = 0.0001). The incidence of pancreatic-cutaneous fistula in the endoscopic escalation step therapy group was significantly lower than that in the open necrosectomy group (RR = 0.11, 95%CI: 0.02–0.58, P = 0.009).Conclusion: Compared with minimally invasive surgery and open necrosectomy, although endoscopic step-up approach cannot reduce the main complications or death and mortality of patients, it can significantly reduce the incidence of some serious complications, such as pancreatic-cutaneous fistula, enterocutaneous fistula, intra-abdominal bleeding, endocrine pancreatic insufficiency, and can significantly shorten the patient's hospital stay.
