RESUMEN
BACKGROUND: Retrosternal oesophageal reconstructions with collar anastomoses can become necessary when the stomach is either unavailable for oesophageal replacement, or orthotopic reconstruction is deemed impractical. Our aim was to analyse our results regarding technical approaches and outcomes. MATERIALS AND METHODS: All patients undergoing primary and secondary oesophageal retrosternal reconstructions with collar anastomoses at our centre (2019-2023) were retrospectively analysed and individual surgical reconstruction options were presented. RESULTS: Overall, twelve patients received primary (n = 5; 42.7%) or secondary (n = 7; 58.3%) reconstructions; ten with colonic interposition and two with gastric pull-up. Male/female ratio was 4:8; median age 66 years (30-87). Charlson-Comorbidity-Score (CCS) was 5 (1-7); 8/12 patients (67%) had ASA-classification score ≥ 3. We observed no conduit necrosis, but one patient (8.3%) with a leakage of the oesophago-colonostomy which was successfully treated by endoscopic vacuum therapy. Four patients (33.3%) acquired nosocomial pneumonia. Additional drainages for pleural fluid collections were necessary in three patients (25%). Overall comprehensive-complication-index (CCI) was 26.2 (0-44.9). Length-of-stay (LOS) was 22 days median (15-40). There was no 90-days mortality. Overall, CCI during the follow-up (FU) period at median 26 months (16-50) was 33.7 (0-100). 10 out of 12 patients were on sufficient oral nutrition at 12 months FU. CONCLUSION: Primary and secondary oesophageal retrosternal reconstructions encompass diverse entities and typically requires tailored decision-making. These procedures, though rare, are feasible with acceptable complication rates and positive functional outcomes when performed in experienced hands.

Importance: Surgical site infections frequently occur after open abdominal surgery. Intraoperative wound irrigation as a preventive measure is a common practice worldwide, although evidence supporting this practice is lacking. Objective: To evaluate the preventive effect of intraoperative wound irrigation with polyhexanide solution. Design, Setting, and Participants: The Intraoperative Wound Irrigation to Prevent Surgical Site Infection After Laparotomy (IOWISI) trial was a multicenter, 3-armed, randomized clinical trial. Patients and outcome assessors were blinded to the intervention. The clinical trial was conducted in 12 university and general hospitals in Germany from September 2017 to December 2021 with 30-day follow-up. Adult patients undergoing laparotomy were eligible for inclusion. The main exclusion criteria were clean laparoscopic procedures and the inability to provide consent. Of 11â¯700 screened, 689 were included and 557 completed the trial; 689 were included in the intention-to-treat and safety analysis. Interventions: Randomization was performed online (3:3:1 allocation) to polyhexanide 0.04%, saline, or no irrigation (control) of the operative wound before closure. Main Outcome and Measures: The primary end point was surgical site infection within 30 postoperative days according to the US Centers for Disease Control and Prevention definition. Results: Among the 689 patients included, 402 were male and 287 were female. The median (range) age was 65.9 (18.5-94.9) years. Participants were randomized to either wound irrigation with polyhexanide (n = 292), saline (n = 295), or no irrigation (n = 102). The procedures were classified as clean contaminated in 92 cases (8%). The surgical site infection incidence was 11.8% overall (81 of 689), 10.6% in the polyhexanide arm (31 of 292), 12.5% in the saline arm (37 of 295), and 12.8% in the no irrigation arm (13 of 102). Irrigation with polyhexanide was not statistically superior to no irrigation or saline irrigation (hazard ratio [HR], 1.23; 95% CI, 0.64-2.36 vs HR, 1.19; 95% CI, 0.74-1.94; P = .47). The incidence of serious adverse events did not differ among the 3 groups. Conclusions and Relevance: In this study, intraoperative wound irrigation with polyhexanide solution did not reduce surgical site infection incidence in clean-contaminated open abdominal surgical procedures compared to saline or no irrigation. More clinical trials are warranted to evaluate the potential benefit in contaminated and septic procedures, including the emergency setting. Trial Registration: drks.de Identifier: DRKS00012251.

PURPOSE: Coronavirus disease 2019 (COVID-19) impacted health care systems around the world. Despite a decrease in emergency admissions, an increased number of complicated forms of diverticulitis was reported. It was the aim of this study to analyze the pandemic impact on diverticulitis management in Germany. METHODS: This is a retrospective population-wide analysis of hospital billing data (2012-2021) of diverticulitis in Germany. Patients were identified based on diagnosis (ICD10) and procedural codes to stratify by conservative and operative management. Primary outcome of interest was admission rates, secondary outcomes were rates of surgical vs conservative treatment and fraction of complicated clinical courses during the pandemic. RESULTS: Of a total of 991,579 cases, 66,424 (6.7%) were admitted during pandemic lockdowns. Conservative treatment was the most common overall (66.9%) and higher during lockdowns (70.7%). Overall admissions and population adjusted rates of surgically treated patients decreased, the latter by 12.7% and 11.3%, corrected to estimated rates, in the two lockdowns. Surgery after emergency presentation decreased by 7.1% (p=0.053) and 11.1% (p=0.002) in the two lockdowns with a higher rate of ostomy and/or revision (+5.6%, p=0.219, and +10.2%, p=0.030). In-hospital mortality was increased in lockdown periods (1.64% vs 1.49%). In detail, mortality was identical in case of conservative treatment during lockdown periods (0.5%) but was higher in surgically treated patients (4.4% vs 3.6%). CONCLUSION: During lockdowns, there was an overall decrease of admissions for diverticulitis, especially non-emergency admissions in Germany, and treatment was more likely to be conservative. In case of surgery, however, there was increased risk of a complicated course (ostomy, re-surgery), possibly due to patient selection.

PURPOSE: A correlation between the hospital volume and outcome is described for multiple entities of oncological surgery. To date, this has not been analyzed for the surgical treatment of sigmoid diverticulitis. The aim of this study was to explore the impact of the annual caseload per hospital of colon resection on the postoperative incidence of complications, failure to rescue, and mortality in patients with diverticulitis. METHODS: Patients receiving colorectal resection independent from the diagnosis from 2012 to 2017 were selected from a German nationwide administrative dataset. The hospitals were grouped into five equal caseload quintiles (Q1-Q5 in ascending caseload order). The outcome analysis was focused on patients receiving surgery for sigmoid diverticulitis. RESULTS: In total, 662,706 left-sided colon resections were recorded between 2012 and 2017. Of these, 156,462 resections were performed due to sigmoid diverticulitis and were included in the analysis. The overall in-house mortality rate was 3.5%, ranging from 3.8% in Q1 (mean of 9.5 procedures per year) to 3.1% in Q5 (mean 62.8 procedures per year; p < 0.001). Q5 hospitals revealed a risk-adjusted odds ratio of 0.85 (95% CI 0.78-0.94; p < 0.001) for in-hospital mortality compared to Q1 during multivariable logistic regression analysis. High-volume centers showed overall lower complication rates, whereas the failure-to-rescue did not differ significantly. CONCLUSION: Surgical treatment of sigmoid diverticulitis in high-volume colorectal centers shows lower postoperative mortality rates and fewer postoperative complications.

BACKGROUND: Gastric (anastomotic or staple-line) leaks after bariatric surgery are rare but potentially life-threatening complications. Endoscopic vacuum therapy (EVT) has evolved as the most promising treatment strategy for leaks associated with upper gastrointestinal surgery. OBJECTIVE: The aim of this study was to evaluate the efficiency of our gastric leak management protocol in all bariatric patients over a 10-year period. Special emphasis was placed on EVT treatment and its outcome as a primary treatment or as a secondary treatment when other approaches failed. SETTING: This study was performed at a tertiary clinic and certified center of reference for bariatric surgery. METHODS: In this retrospective single-center cohort study, clinical outcomes of all consecutive patients after bariatric surgery from 2012 to 2021 are reported, with special emphasis placed on gastric leak treatment. The primary endpoint was successful leak closure. Secondary endpoints were overall complications (Clavien-Dindo classification) and length of stay. RESULTS: A total of 1046 patients underwent primary or revisional bariatric surgery, of whom 10 (1.0%) developed a postoperative gastric leak. Additionally, 7 patients were transferred for leak management after external bariatric surgery. Of these, 9 patients underwent primary and 8 patients underwent secondary EVT after futile surgical or endoscopic leak management. The efficacy of EVT was 100%, and there were no deaths. Complications did not differ between primary EVT and secondary treatment of leaks. Length of treatment was 17 days for primary EVT versus 61 days for secondary EVT (P = .015). CONCLUSIONS: EVT for gastric leaks after bariatric surgery led to rapid source control with a 100% success rate both as primary and secondary treatment. Early detection and primary EVT shortened treatment time and length of stay. This study underlines the potential of EVT as a first-line treatment strategy for gastric leaks after bariatric surgery.

BACKGROUND: Perioperative bridging of oral anticoagulation increases the risk of bleeding complications after elective general and visceral surgery. The aim of this study was to explore, whether an individual risk-adjusted bridging regimen can reduce bleeding events, while still protecting against thromboembolic events. METHODS: We performed a quality improvement study comparing bridging parameters and postoperative outcomes before (period 1) and after implementation (period 2) of a new risk-adjusted bridging regimen. The primary endpoint of the study was overall incidence of postoperative bleeding complications during 30 days postoperatively. Secondary endpoints were major postoperative bleeding, minor bleeding, thromboembolic events, postoperative red blood cell transfusion, perioperative length-of-stay (LOS) and in-hospital mortality. RESULTS: A total of 263 patients during period 1 and 271 patients during period 2 were compared. The included elective operations covered the entire field of general and visceral surgery. The overall incidence of bleeding complications declined from 22.1% during period 1 to 10.3% in period 2 (p < 0.001). This reduction affected both major as well as minor bleeding events (8.4% vs. 4.1%; p = 0.039; 13.7% vs. 6.3%; p = 0.004). The incidence of thromboembolic events remained low (0.8% vs. 1.1%). No changes in mortality or length-of-stay were observed. CONCLUSION: It is important to balance the individual thromboembolic and bleeding risks in perioperative bridging management. The risk adjusted bridging regimen reduces bleeding events in general and visceral surgery while the risk of thromboembolism remains comparably low.

BACKGROUND: Pancreatic adenocarcinoma (PDAC) patients with preoperative carbohydrate antigen 19-9 (CA19-9) serum levels higher than 500 U/ml are classified as biologically borderline resectable (BR-B). To date, the impact of cholestasis on preoperative CA19-9 serum levels in these patients has remained unquantified. METHODS: Data on 3079 oncologic pancreatic resections due to PDAC that were prospectively acquired by the German Study, Documentation and Quality (StuDoQ) registry were analyzed in relation to preoperative CA19-9 and bilirubin serum values. Preoperative CA19-9 values were adjusted according to the results of a multivariable linear regression analysis of pathologic parameters, bilirubin, and CA19-9 values. RESULTS: Of 1703 PDAC patients with tumor located in the pancreatic head, 420 (24.5 %) presented with a preoperative CA19-9 level higher than 500 U/ml. Although receiver operating characteristics (ROC) analysis failed to determine exact CA19-9 cut-off values for prognostic indicators (R and N status), the T, N, and G status; the UICC stage; and the number of simultaneous vein resections increased with the level of preoperative CA19-9, independently of concurrent cholestasis. After adjustment of preoperative CA19-9 values, 18.5 % of patients initially staged as BR-B showed CA19-9 values below 500 U/ml. However, the postoperative pathologic results for these patients did not change compared with the patients who had CA19-9 levels higher than 500 U/ml after bilirubin adjustment. CONCLUSIONS: In this multicenter dataset of PDAC patients, elevation of preoperative CA19-9 correlated with well-defined prognostic pathologic parameters. Bilirubin adjustment of CA19-9 is feasible but does not affect the prognostic value of CA19-9 in jaundiced patients.

PURPOSE: In selected cases of severe Cushing's syndrome due to uncontrolled ACTH secretion, bilateral adrenalectomy appears unavoidable. Compared with unilateral adrenalectomy (for adrenal Cushing's syndrome), bilateral adrenalectomy has a perceived higher perioperative morbidity. The aim of the current study was to compare both interventions in endogenous Cushing's syndrome regarding postoperative outcomes. METHODS: We report a single-center, retrospective cohort study comparing patients with hypercortisolism undergoing bilateral vs. unilateral adrenalectomy during 2008-2021. Patients with adrenal Cushing's syndrome due to adenoma were compared with patients with ACTH-dependent Cushing's syndrome (Cushing's disease and ectopic ACTH production) focusing on postoperative morbidity and mortality as well as long-term survival. RESULTS: Of 83 patients with adrenalectomy for hypercortisolism (65.1% female, median age 53 years), the indication for adrenalectomy was due to adrenal Cushing's syndrome in 60 patients (72.2%; 59 unilateral and one bilateral), and due to hypercortisolism caused by Cushing's disease (n = 16) or non-pituitary uncontrolled ACTH secretion of unknown origin (n = 7) (27.7% of all adrenalectomies). Compared with unilateral adrenalectomy (n = 59), patients with bilateral adrenalectomy (n = 24) had a higher rate of severe complications (0% vs. 33%; p < 0.001) and delayed recovery (median: 10.2% vs. 79.2%; p < 0.001). Using the MTL30 marker, patients with bilateral adrenalectomy fared worse than patients after unilateral surgery (MTL30 positive: 7.2% vs. 25.0% p < 0.001). Postoperative mortality was increased in patients with bilateral adrenalectomy (0% vs. 8.3%; p = 0.081). CONCLUSION: While unilateral adrenalectomy for adrenal Cushing's syndrome represents a safe and definitive therapeutic option, bilateral adrenalectomy to control ACTH-dependent extra-adrenal Cushing's syndrome or Cushing's disease is a more complicated intervention with a mortality of nearly 10%.

Background: Although abdominal foci are the second most common source of sepsis, only few studies focus on the optimal length of post-operative antibiotic therapy in critically ill patients with abdominal sepsis. The aim of this study was to compare the outcomes of short versus long antibiotic therapy as well as broad-spectrum penicillin versus carbapenem in patients with abdominal sepsis. Patients and Methods: We performed a single center retrospective study in patients with abdominal sepsis who underwent emergency surgery. The study was conducted in a tertiary hospital in Germany during 2016-2018. We reviewed the duration of post-operative antibiotic therapy and the initially used agent, comparing patients treated shorter or longer than seven days with or without source control. Depending on the empirically given antibiotic, a subgroup analysis was conducted comparing patients treated with piperacillin-tazobactam versus carbapenems. Results: Longer duration of post-operative antibacterial treatment (>7 days) was not substantially advantageous. The group with a longer course of antibiotic therapy had more severe post-operative complications (82.4% [n = 61] vs. 62.5% [n = 20]; p = 0.01) requiring longer critical care support (18 days vs. 11 days; p = 0.027), prolonging the length of stay (28 days vs. 20 days; p = 0.044). Surgical re-interventions were more frequent in the long-course arm (70.3% vs. 40.6%; p = 0.004). The subgroup analysis comparing piperacillin-tazobactam versus carbapenems confirmed more severe complications (86.3% vs. 67.5%; p = 0.04) for the carbapenem arm. Conclusions: Post-surgical continuation of antibiotic agents beyond seven days was observed with more post-operative complications and delayed recovery. Piperacillin-tazobactam seems to be a potent alternative for patients with abdominal sepsis.

BACKGROUND: The adequate choice of perioperative antibiotic prophylaxis (PAP) could influence the risk of surgical site infections (SSIs) in general surgery. A new local PAP guideline was implemented in May 2017 and set the first-generation cefazolin (CFZ) instead the second-generation cefuroxime (CXM) as the new standard prophylactic antibiotic. The aim of this study was to compare the risk of SSIs after this implementation in intra-abdominal infections (IAIs) without sepsis. METHODS: We performed a single center-quality improvement study at a 1500 bed sized university hospital in Germany analyzing patients after emergency surgery during 2016 to 2019 (n = 985), of which patients receiving CXM or CFZ were selected (n = 587). Propensity score matching was performed to ensure a comparable risk of SSIs in both groups. None-inferiority margin for SSIs was defined as 8% vs. 4%. RESULTS: Two matched cohorts with respectively 196 patients were compared. The rate of SSIs was higher in the CFZ group (7.1% vs. 3.6%, p = 0.117) below the non-inferiority margin. The rate of other postoperative infections was significantly higher in the CFZ group (2.0% vs. 8.7%, p = 0.004). No other differences including postoperative morbidity, mortality or length-of-stay were observed. CONCLUSION: Perioperative antibiotic prophylaxis might be safely maintained by CFZ even in the treatment of intra-abdominal infections.
RESUMEN
BACKGROUND: Recent evidence suggests that short-course postoperative antibiotic therapy (PAT) of intra-abdominal infections is non-inferior considering clinical outcomes. The aim of this study was to compare the outcome of short vs. long PAT in complicated intra-abdominal infections (cIAIs) without sepsis. METHODS: We performed a single center-quality improvement study at a 1500 bed sized university hospital in Bavaria, Germany, with evaluation of the length of antibiotic therapy after emergency surgery on cIAIs with adequate source control during 2016 to 2018. We reviewed a total of 260 cases (160 short duration vs. 100 long duration). The antibiotic prescribing quality was assessed by our in-house antimicrobial stewardship team (AMS). RESULTS: No significant differences of patient characteristics were observed between short and long PAT. The frequency of long PAT declined during the observation period from 48.1% to 26.3%. Prolongation of PAT was not linked with any clinical benefits, on the contrary clinical outcome of patients receiving longer regimes were associated with higher postoperative morbidity. AMS identified additional educational targets to improve antibiotic prescribing quality on general wards like unnecessary postoperative switches of antibiotic regimes, e.g., unrequired switches to oral antibiotics as well as prolongation of PAT due to elevated CRP. CONCLUSION: Short-course antibiotic therapy after successful surgical source control in cIAIs is safe, and long-duration PAT has no beneficial effects.
RESUMEN
BACKGROUND: Due to the COVID-19-related lockdown regulations, surgical clinics had to cut down elective procedures. The impact of the cancellation and postponing surgery on patients is unclear. METHODS: All patients from six hospitals with canceled surgery during the first lockdown (03/16-04/24/2020) were asked to answer a questionnaire. RESULTS: In total, 225 patients took part. In 88 (39.1%) patients, the disease-related complaints changed, mainly towards an increase in severity (82.6%). That was especially true for hernia patients (44.4%). In 4% of the cases, there was a complication requiring surgery in the time interval between the original date of the operation and the interview. For about a third, the cancelation of scheduled surgery caused major administrative difficulties. Most of the patients (76.3%) understood the measures taken, though 40.4% of them considered that their indication was very urgent. DISCUSSION AND CONCLUSION: The overall complication rate was low, and patients agreed to the measures taken; however, especially hernia patients showed increasing symptoms and some acute incarcerations. It seems reasonable to monitor symptomatic patients closely, in order to prioritise them when surgical capacity is restricted.

The burden of surgical site infections (SSIs) is increasing. The number of surgical procedures continues to rise, and surgical patients present increasingly complex comorbidities. Half of SSIs are deemed preventable using evidence-based strategies. It is recommended for patients to bathe or shower prior to surgery. Hair should be removed only with a clipper. Shaving is strongly discouraged at all times. Antimicrobial prophylaxis should be administered only when indicated, based on guidelines, and timed correctly in order to achieve a bactericidal concentration in the tissues when the incision is made. Prophylaxis must not be continued beyond surgery. For skin preparation in the operating room an alcohol-based agent plus chlorhexidine or octenidine is recommended. During surgery, glycemic control and goal-directed fluid therapy should be implemented. Normothermia should be targeted in all patients. The perioperative use of an increased fraction of inspired oxygen may reduce the risk of SSI. Using a surgical safety checklist during a team time-out immediately before surgery reduces the incidence of SSI.

BACKGROUND: Liver resection is the most effective available therapy for patients with hepatocellular carcinoma (HCC). The accurate selection of patients for surgery requires determination of technical resectability and the risk of recurrence, as well as assessment of liver function and functional reserve to avoid postoperative liver failure. Previous studies have underlined the effectiveness and reliability of the LiMAx® test to evaluate liver function preoperatively. Nevertheless, data concerning HCC evaluation are lacking. METHODS: From 2014 to 2019, 92 patients with HCC underwent additional assessment of liver function using the LiMAx test prior to decision for or against liver resection. Preoperative LiMAx results were compared between cirrhotic and noncirrhotic liver. The clinical decision for surgery was evaluated applying the various liver function parameters available. RESULTS: Forty-six patients underwent liver resection. The LiMAx results were higher in resected patients (388 vs. 322 µg/kg/h; p = 0.004). LiMAx values were an independent risk factor for the presence of liver cirrhosis in multivariate analysis. In 17 patients, surgical treatment was cancelled due to major impairment of liver function. Only 4 out of 46 resected patients presented with post-hepatectomy liver failure (PHLF) grade ≥B. Histologic assessment revealed liver cirrhosis in 10 resected patients without PHLF. CONCLUSION: Preoperative determination of liver function by the LiMAx test enables effective and safe patient selection for HCC resection in both cirrhotic and noncirrhotic liver.
RESUMEN
BACKGROUND: The aim of this study was to assess the impact of antimicrobial stewardship interventions on surgical antibiotic prescription behavior in the management of non-elective surgical intra-abdominal infections, focusing on postoperative antibiotic use, including the appropriateness of indications. METHODS: A single-center quality improvement study with retrospective evaluation of the impact of antimicrobial stewardship measures on optimizing antibacterial use in intra-abdominal infections requiring emergency surgery was performed. The study was conducted in a tertiary hospital in Germany from January 1, 2016, to January 30, 2020, three years after putting a set of antimicrobial stewardship standards into effect. RESULTS: 767 patients were analyzed (n = 495 in 2016 and 2017, the baseline period; n = 272 in 2018, the antimicrobial stewardship period). The total days of therapy per 100 patient days declined from 47.0 to 42.2 days (p = 0.035). The rate of patients receiving postoperative therapy decreased from 56.8% to 45.2% (p = 0.002), comparing both periods. There was a significant decline in the rate of inappropriate indications (17.4% to 8.1 %, p = 0.015) as well as a significant change from broad-spectrum to narrow-spectrum antibiotic use (28.8% to 6.5%, p ≤ 0.001) for postoperative therapy. The significant decline in antibiotic use did not affect either clinical outcomes or the rate of postoperative wound complications. CONCLUSIONS: Postoperative antibiotic use for intra-abdominal infections could be significantly reduced by antimicrobial stewardship interventions. The identification of inappropriate indications remains a key target for antimicrobial stewardship programs.
RESUMEN
BACKGROUND: In the past, for a number of abdominal surgical interventions a correlation between treatment volume of a hospital and the patient's outcome was shown in national and international studies. METHODS: Based on a systematic literature search we analyzed the absolute and risk-adjusted in-house lethality as well as the rate of complications and the failure to rescue after abdominal surgery in Germany. The hospitals were grouped in quintiles according to the volume of treatment. RESULTS: 11 studies including more than 2 million patients were identified and surgeries for the treatment of 9 disease conditions were studied. The meta-analysis shows a significantly lower absolute and risk-adjusted in-house mortality for surgery in hospitals with high treatment volumes compared to low volume hospitals. In the context of subgroup analysis, this effect is demonstrated especially for complex surgical procedures. The failure to rescue in patients suffering from sepsis is significantly lower in high volume centers compared to low volume centers. CONCLUSION: This systematic review and meta-analysis shows on more than 2 million patients that there is a volume-outcome relationship for the surgical treatment of abdominal diseases in Germany across various organ systems, which is particularly true for complex interventions.
