ABSTRACT
Background and Objectives: Though widely used, only limited data is available that shows the superiority of hybrid minimally-invasive esophagectomy (HMIE) compared to open esophagectomy (OE). The present study aimed to analyze postoperative morbidity, mortality, and compare lengths of hospital stay. Materials and Methods: A total of 174 patients underwent Ivor Lewis esophagectomy in our surgical department, of which we retrospectively created a matched population of one hundred (HMIE n = 50, OE n = 50). Morbidity and mortality data was categorized, analyzed, and risk factor analyzed for complications. Results: The oncological results were found to be comparable in both groups. A median of 23.5 lymphnodes were harvested during OE, and 21.0 during HMIE. Negative tumor margins were achieved in 98% of OE and 100% of HMIE. In-hospital mortality rate showed no significant difference between techniques (OE 14.0%, HMIE 4.0%, p = 0.160). Hospital (OE Median 23.00 days, HMIE 16.50 days, p = 0.004) and ICU stay (OE 5.50 days, HMIE 3.00 days, p = 0.003) was significantly shorter after HMIE. The overall complication rate was 50%, but complications in general (OE 70.00%, HMIE 30%, p < 0.001) as well as severe complications (Clavien Dindo ≥ III: HMIE 16.0%, OE 48.0%, p < 0.001) were significantly more common after OE. In multivariate stepwise regressions the influence of OE proved to be independent for said outcomes. We observed more pulmonary complications in the OE group (46%) compared to HMIE patients (26%). This difference was statistically significant after adjustment for sex, age, BMI, ASA classification, histology, neoadjuvant treatment or not, smoking status, cardiac comorbidities, diabetes mellitus, and alcohol abuse (p = 0.019). Conclusions: HMIE is a feasible technique that significantly decreases morbidity, while ensuring equivalently good oncological resection compared to OE. HMIE should be performed whenever applicable for patients and surgeons.

BACKGROUND: Abdominal symptoms after cholecystectomy may be caused by gallstones in a remnant gallbladder or a long cystic duct stump. Resection of a remnant gallbladder or cystic duct stump is associated with an increased risk of conversion and bile duct or vascular injuries. We prospectively investigated the additional value of robotic assistance and fluorescent bile duct illumination in redo biliary surgery. METHODS: In this prospective two-centre observational cohort study, 28 patients were included with an indication for redo biliary surgery because of remnant stones in a remnant gallbladder or long cystic duct stump. Surgery was performed with the da Vinci X® and Xi® robotic system. The biliary tract was visualised in the fluorescence Firefly® mode shortly after intravenous injection of indocyanine green. RESULTS: There were no conversions or perioperative complications, especially no vascular or bile duct injuries. Fluorescence-based illumination of the extrahepatic bile ducts was successful in all cases. Symptoms were resolved in 27 of 28 patients. Ten patients were treated in day care and 13 patients were discharged the day after surgery. CONCLUSION: Robot-assisted fluorescence-guided surgery for remnant gallbladder or cystic duct stump resection is safe, effective and can be done in day-care setting.

Despite a significant decrease of surgery-related mortality and morbidity, anastomotic leakage still occurs in a significant number of patients after esophagectomy. The two main endoscopic treatments in case of anastomotic leakage are self-expanding metal stents (SEMS) and the endoscopic vacuum therapy (EVT). It is still under debate, if one method is superior to the other. Therefore, we performed a systematic review and meta-analysis of the existing literature to compare the effectiveness and the related morbidity of SEMS and EVT in the treatment of esophageal leakage. We systematically searched for studies comparing SEMS and EVT to treat anastomotic leak after esophageal surgery. Predefined endpoints including outcome, treatment success, endoscopy, treatment duration, re-operation rate, intensive care and hospitalization time, stricture rate, morbidity and mortality were assessed and included in the meta-analysis. Seven retrospective studies including 338 patients matched the inclusion criteria. Compared to stenting, EVT was significantly associated with higher healing (OR 2.47, 95% CI [1.30 to 4.73]), higher number of endoscopic changes (pooled median difference of 3.57 (95% CI [2.24 to 4.90]), shorter duration of treatment (pooled median difference - 11.57 days; 95% CI [- 17.45 to - 5.69]), and stricture rate (OR 0.22, 95% CI [0.08 to 0.62]). Hospitalization and intensive care unit duration, in-hospital mortality rate, rate of major and treatment related complications, of surgical revisions and of esophago-tracheal fistula failed to show significant differences between the two groups. Our analysis indicates a high potential for EVT, but because of the retrospective design of the included studies with potential biases, these results must be interpreted with caution. More robust prospective randomized trials should further investigate the potential of the two procedures.

BACKGROUND: After gastrectomy or esophagectomy, esophagogastrostomy and esophagojejunostomy are commonly used for reconstruction. Water-soluble contrast swallow is often used as a routine screening to exclude anastomotic leakage during the first postoperative week. In this retrospective study, the sensitivity and specificity of oral water-soluble contrast swallow for the detection of anastomotic leakage and its clinical symptoms were analysed. MATERIAL/METHODS: Records of 104 consecutive total gastrectomies and distal esophagectomies were analysed. In all cases, upper gastrointestinal contrast swallow with the use of a water-soluble contrast agent was performed on the 5th postoperative day. Extravasation of the contrast agent was defined as anastomotic leakage. When anastomotic insufficiency was suspected but no extravasation was present, a computed tomography (CT) scan and upper endoscopy were performed. RESULTS: Oral contrast swallow detected 7 anastomotic leaks. Based on CT-scans and upper endoscopy, the true number of anastomotic leakage was 15. The findings of the oral contrast swallow were falsely positive in 4 and falsely negative in 12 patients, respectively. The sensitivity and specificity of the oral contrast swallow was 20% and 96%, respectively. CONCLUSIONS: Routine radiological contrast swallow following total gastrectomy or distal esophagectomy cannot be recommended. When symptoms of anastomotic leakage are present, a CT-scan and endoscopy are currently the methods of choice.
ABSTRACT
Introduction: Anastomotic leakage after esophagectomy with gastric-pullup is the most feared postoperative complication associated with high morbidity and mortality rates. Management of anastomotic leakage underwent an evolution in the last decade from surgical and conservative to an endoscopic management. However, to date there is no clear consensus on management and if endoluminal vacuum therapy (EVT) is the most superior therapy. Material and methods: Between 2012 and 2022 all patients that underwent Ivor-Lewis esophagectomy for an underlying malignancy were included in this study. Patients that developed an anastomotic leakage and received endoscopic vacuum therapy were further analysed. Results: A total of 17 patients were treated with EVT following AL after esophagectomy. The median duration of EVT was 23 days with a median number of 5,5 vacuum sponge changes per patient. EVT-systems were placed 12 times intraluminal and 5 times extraluminal. Successful closure of the defect was achieved in 14 patients. Conclusion: Endoscopic vacuum therapy can be successfully applied in the treatment of anastomotic leakage after esophagectomy even in septic patients with an extraluminal cavity. Event-related complications are present but rare.
ABSTRACT
INTRODUCTION: Anastomotic leakage (AL) following oesophageal surgery is the most feared complication. Therefore, it is of utmost importance to diagnose it in a timely and safe manner. The diagnostic algorithm, however, differs across institutions world-wide, with no clear consensus or guidelines. The aim of this study was to analyse whether computed tomography (CT) or upper endoscopy (UE) should be performed first. MATERIAL AND METHODS: Records of 185 patients undergoing oesophageal surgery for underlying malignancy were analysed. All patients that developed an AL were further analysed. Results of CT and UE were compared to calculate sensitivity. RESULTS: Overall, 33 out of 185 patients were diagnosed with an AL after oesophagectomy. All patients received a CT and a UE. The CT identified 23 out of 33 patients correctly. Sensitivity was 69.7% for CT, compared to 100% for UE. CONCLUSION: If patients are clinically suspicious regarding development of an AL after oesophagectomy, UE should be performed prior to CT as it has a sensitivity of 100%. In addition, treatment by means of endoluminal vacuum therapy (EVT) or self-expanding-metal stents (SEMS) can be initiated promptly.
ABSTRACT
Background: Postoperative anastomotic leakage remains a major complication of esophagectomy. The development of a reliable method of early detection of anastomotic leakage can revolutionize the management of esophageal carcinoma. Materials and Methods: This is a retrospective data analysis of 147 patients who underwent Ivor-Lewis esophagectomy as a curative attempt to treat distal esophageal carcinoma in our surgery department between 2010 and 2021. C-reactive protein and white blood cell count in postoperative days 1, 3, 5, and 8 were compared in patients with and without anastomotic leakage. The diagnostic accuracy of these tests was challenged against the clinical reference standard represented by computed tomography or upper gastrointestinal endoscopy. Results: Twenty-eight patients (19%) developed anastomotic leakage. C-reactive protein values in postoperative day 8 were the only parameter to qualify as a potential clinically helpful test with an area under the receiver operating curve of 0.85 and a P value of less than .01. We calculated the cutoff value for C-reactive protein during postoperative day 8 to be 10.85â¯mg/dL with specificity and sensitivity of 73.1% and 89.3%, respectively. C-reactive protein showed a positive predictive value of 43.9% and a negative predictive value of 96.7% at this cutoff value. Conclusion: An absolute diagnostic value of postoperative estimation of serum inflammatory biomarkers to detect anastomotic leakage could not be proved. Serum C-reactive protein on postoperative day 8 with a cutoff value of 10.85â¯mg/dL could be used to exclude anastomotic leakage after esophagectomy to serve as one of the discharge criteria of the patients.
ABSTRACT
Aim: Surgical resection remains the treatment of choice for curable esophageal cancer patients. Anastomotic leakage after esophagectomy with an intrathoracic anastomosis is the most feared complication, and is the main cause of postoperative morbidity and mortality. The aim of this study was to identify risk factors associated with anastomotic leakage and its effect on the postoperative outcome. Methods: Between 2012 and 2022, all patients who underwent Ivor Lewis esophagectomy for underlying malignancy were included in this study. We performed a retrospective analysis of 174 patients. The dataset was analyzed to identify risk factors for the occurrence of anastomotic leakage. Results: A total of 174 patients were evaluated. The overall anastomotic leakage rate was 18.96%. The 30-day mortality rate was 8.62%. Multivariate logistic regression analysis identified diabetes (p = 0.0020) and obesity (p = 0.027) as independent risk factors associated with anastomotic leakage. AL had a drastic effect on the combined ICU/IMC and overall hospital stay (p < 0.001. Conclusion: Anastomotic leakage after esophagectomy with intrathoracic anastomosis is the most feared complication and major cause of morbidity and mortality. Identifying risk factors preoperatively can contribute to better patient management.
ABSTRACT
BACKGROUND/AIMS: Anastomotic leakage after esophageal surgery remains a feared complication. During the last decade, management of this complication changed from surgical revision to a more conservative and endoscopic approach. However, the treatment remains controversial as the indications for conservative, endoscopic, and surgical approaches remain non-standardized. METHODS: Between 2010 and 2020, all patients who underwent Ivor Lewis esophagectomy for underlying malignancy were included in this study. The data of 28 patients diagnosed with anastomotic leak were further analyzed. RESULTS: Among 141 patients who underwent resection, 28 (19.9%) developed an anastomotic leak, eight (28.6%) of whom died. Thirteen patients were treated with endoluminal vacuum therapy (EVT), seven patients with self-expanding metal stents (SEMS) four patients with primary surgery, one patient with a hemoclip, and three patients were treated conservatively. EVT achieved closure in 92.3% of the patients with a large defect and no EVT-related complications. SEMS therapy was successful in clinically stable patients with small defect sizes. CONCLUSION: EVT can be successfully applied in the treatment of anastomotic leakage in critically ill patients, while SEMS should be limited to clinically stable patients with a small defect size. Surgery is only warranted in patients with sepsis with graft necrosis.
ABSTRACT
Objectives: Perforation of the esophagus is an extremely rare but life-threatening emergency associated with a high morbidity and mortality. Therefore, time-management is of utmost importance and it is crucial to have an algorithm for diagnostic methods and the subsequent decision-making process. Material and Methods: All patients who were diagnosed with an esophageal perforation between 2010 and 2020 at our university hospital were ret- rospectively analysed. In addition to patient demographics, the diagnostic method, treatment strategy, defect size and location, etiology and mortality were recorded. Results: A total of 27 patients were identified with an esophageal perforation. All patients were diagnosed through a computed tomography initiat- ing the treatment algorithm 18 patients underwent conservative/endoscopic treatment, while 9 patients received primary surgery for event-related complications. The overall mortality rate was 25.9%, 11.1% within the endoscopic group and 55% within the surgical group. Conclusion: A timely diagnosis in cases of an esophageal perforation is of utmost importance. Therefore, every patient should undergo an emergency computed tomography (CT) with oral and intravenous contrast followed by an upper endoscopy if event-related complications are ruled out in the CT.
ABSTRACT
BACKGROUND/AIM: miRNA expression patterns vary within primary rectal cancers and play a pivotal role in carcinogenesis. It is unknown, however, if these regulatory changes also play a role in local recurrent rectal cancers. In this study, the expression of various angiogenetic small non-coding ribonucleic acids, namely miRNA-21, miRNA-215, miRNA-221, and miRNA-222 were analysed in cancerous and healthy rectal tissues. PATIENTS AND METHODS: miRNA expression was analyzed via quantitative polymerase chain reaction (qPCR). Samples were obtained from 20 patients who were treated for local recurrent rectal cancer at the Department for general and visceral surgery, Klinikum Oldenburg, Germany. RESULTS: No significant differences in the expression of miRNA-221, miRNA-222 and miRNA-215 were observed between cancerous and healthy rectal tissues. However, a significant differential expression was detected for miRNA-21. CONCLUSION: miRNA-21 is differentially expressed in recurrent rectal cancer tissue and healthy tissues. However, miRNA-215, miRNA-221 and miRNA-222 are not significantly differentially expressed.

Transsphincteric resection of rectal tumors was first described about 120 years ago. Nowadays, this approach faded into obscurity due to standardized guidelines and practice in surgical oncology including lymphadenectomy, mesorectal excision and radical dissection of veins. However, transsphincteric resection seems reasonable in some cases, especially if an abdominal approach can be avoided. In the following, we will present and describe the technique of the transsphincteric approach with its variations in rectal surgery in the case of a rare pararectal tumor.
ABSTRACT
BACKGROUND: Malignant melanoma is a tumor with common lymphogenic or hematogenic metastasis. Metastasis to the gastric mucosa is uncommon. CASE REPORT: We present the case of a 43-year-old female patient with metastases of a malignant melanoma to the lesser curvature of the stomach. The primary malignant melanoma of the right breast was resected 2 years previously. CONCLUSION: Metastases to the gastric mucosa are rarely seen. Esophagogastroduodenoscopy should be performed in symptomatic patients to rule out metastatic disease. When R0 resection can be achieved, it should be undertaken in order to increase the overall prognosis of the patient.
ABSTRACT
The higher incidence of gallstone formation after gastrectomy for cancer has been reported as a common complication in many studies but the management strategies are still controversial and need further evaluation. We retrospectivaly analysed between 2007 and 2013, 206 patients who underwent gastric and or oesophageal resection. In 29/93 patients receiving an oesophagectomy a simultaneous cholecystectomy was performed, respectively 31 from 111 patients who underwent a gastrectomy received an incidental cholecystectomy. In 2 patients with an extended gastrectomy, the gallblader removing was performed simultaneously in one case. A subsequent cholecystectomy was performed in 11 cases. The increased surgical mortality was significant higher correlated with an intervention at a later stage point. That suggest that the prohylactic cholecystectomy can be safely performed during a major intervention in order to reduce complication and a reoperation.

BACKGROUND: The combination of right sided portal vein ligation and hepatic parenchymal transection thus inducing a hypertrophy of the left or left lateral sector is an innovative treatment option in treating locally advanced hepatic tumors or hepatic metastases. The available published data regarding this procedure is weak. We analyzed our own data regarding tumor recurrence and complications. The data was then used to be critically analyzed using the available published literature. METHODS: We treated n = 5 patients with an ALPPS (associating liver partition and portal vein ligation for staged hepatectomy). The follow-up was 3 years. We analyzed the perioperative period, complications, mortality and oncological survival rate. RESULTS: In all patients (n = 5) a R0-resection was achieved. N = 1 patient died postoperatively. N = 1 patient died 6 month later due to a pulmonary embolism. N = 3 patients had a tumor recurrence within 6 months. CONCLUSION: Selected patients can be successfully treated by ALPPS in terms of an R0-resection. However, risk of tumor recurrence and rate of complications are high.
