Western European Variation in the Organization of Esophageal Cancer Surgical Care.

Reasons for structural and outcome differences in esophageal cancer surgery in Western Europe remain unclear. This questionnaire study aimed to identify differences in the organization of esophageal cancer surgical care in Western Europe. A cross-sectional international questionnaire study was conducted among upper gastrointestinal (GI) surgeons from Western Europe. One surgeon per country was selected based on scientific output and active membership in the European Society for Diseases of the Esophagus or (inter)national upper GI committee. The questionnaire consisted of 51 structured questions on the structural organization of esophageal cancer surgery, surgical training, and clinical audit processes. Between October 2021 and October 2022, 16 surgeons from 16 European countries participated in this study. In 5 countries (31%), a volume threshold was present ranging from 10 to 26 annual esophagectomies, in 7 (44%) care was centralized in designated centers, and in 4 (25%) no centralizing regulations were present. The number of centers performing esophageal cancer surgery per country differed from 4 to 400, representing 0.5-4.9 centers per million inhabitants. In 4 countries (25%), esophageal cancer surgery was part of general surgical training and 8 (50%) reported the availability of upper GI surgery fellowships. A national audit for upper GI surgery was present in 8 (50%) countries. If available, all countries use the audit to monitor the quality of care. Substantial differences exist in the organization and centralization of esophageal cancer surgical care in Western Europe. The exchange of experience in the organizational aspects of care could further improve the results of esophageal cancer surgical care in Europe.

Role of Radiology in the Preoperative Detection of Arterial Calcification and Celiac Trunk Stenosis and Its Association with Anastomotic Leakage Post Esophagectomy, an Up-to-Date Review of the Literature.

Surgical resection of the esophagus remains a critical component of the multimodal treatment of esophageal cancer. Anastomotic leakage (AL) is the most significant complication following esophagectomy, in terms of clinical implications. Identifying risk factors for AL is important for modifying patient management and improving surgical outcomes. This review aims to examine the role of radiological risk factors for AL after esophagectomy, and in particular, arterial calcification and celiac trunk stenosis. Eligible publications prior to 25 August 2021 were retrieved from Medline and Google Scholar using a predefined search algorithm. A total of 68 publications were identified, of which 9 original studies remained for in-depth analysis. The majority of these studies found correlations between calcifications in the aorta, celiac trunk, and right post-celiac arteries and AL following esophagectomy. Some studies suggest celiac trunk stenosis as a more appropriate surrogate. Our up-to-date review highlights the need for automated quantification of aortic calcifications, as well as the degree of celiac trunk stenosis in preoperative computed tomography in patients undergoing esophagectomy, to obtain robust and reproducible measurements that can be used for a definite correlation.

Venous thromboembolism after esophagectomy for cancer: a systematic review of the literature to evaluate incidence, risk factors, and prophylaxis.

PURPOSE: Although esophagectomy remains the preferred treatment for esophageal cancer, it is still associated with a number of complications, including post-operative venous thromboembolism (VTE). The aim of this study was to summarize the reported incidence of VTE after esophagectomy, its risk factors, and prevention strategies. METHODS: We conducted a systematic search of the literature in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: Fourteen studies met our inclusion criteria and were selected in the present review. Overall, we identified 9768 patients who underwent esophagectomy, with a post-operative VTE rate of 4% (440 patients). The reported risk factors for VTE included advanced age, American Society of Anesthesiologists (ASA) class III or IV, a history of cardiovascular or pulmonary disease, and the implementation of preoperative chemo-radiotherapy. Postoperative acute respiratory distress syndrome was also associated with VTE. No universally applied prevention strategies for VTE after esophagectomy were identified in the literature. CONCLUSIONS: Despite advances in perioperative care, VTE after esophagectomy still represents a source of morbidity for about 4% of patients. Low molecular weight heparin is suggested as the routine standard prophylactic regimen after esophageal cancer surgery.

Papillary thyroid carcinoma micro-deposits in cervical lymph nodes without intra-thyroid malignancy: A comment in consideration of the latest American Thyroid Association guidelines.

Differentiated thyroid cancer (DTC) represents the vast majority of all thyroid cancers, with the papillary variant being the most common. According to the previous 2009 American Thyroid Association (ATA) guidelines, papillary thyroid microcarcinoma (PTMC; ≤1 cm in diameter) exhibiting cervical lymph node metastasis corresponded to an intermediate-risk group for recurrence or metastasis. However, the latest 2015 ATA guidelines advocate that a patient with PTMC is low-risk if there are ≤5 regional node micrometastases. This means that therapeutic radioactive iodine (RAI) is not required. The current study reports a rare case of a patient who underwent total thyroidectomy due to multi-nodular goiter where the pathologic specimen exhibited two PTMC foci in regional lymph nodes, but no primary cancer was identified in the thyroid despite thorough examination of the thyroid parenchyma. The etiology of such results is unknown and it was hypothesized that it may be the consequence of insufficient pathologic examination or due to the regression of a primary PTMC in the thyroid. Moreover, the risk-stratification of cases with intra-lymph node PTMC without any evidence of primary cancer in the thyroid is not considered in the ATA recommendations. The aim of the current report was to elucidate the risk-stratification of this rare occurrence and to reconsider the possible etiologies. By extrapolating the latest ATA recommendations concerning a patient with a known primary PTMC and ≤5 metastatic micro-foci (thus the only difference between cases being the absence of a primary tumor), it was concluded that the patient should be considered low-risk. As a consequence, RAI therapy should be deemed as unnecessary despite the presence of lymph node microfoci. Moreover, it was proposed that cervical lymph node PTMC with no evidence of a primary tumor in the thyroid could be the consequence of normal thyroid tissue micro-deposit progression to cancer within the lymph node, which is a rare benign entity.

Presentation of gastroesophageal junction adenocarcinoma with synchronous metastases at the small intestine. Could treatment with curative intent be considered? A case report.

INTRODUCTION: Introduction of multimodality treatment as the standard of care for management of esophageal and gastroesophageal junction (GEJ) cancer over the last years has led to significant improvement in survival for patients with localized disease. Nevertheless, treatment with curative intent is not considered in the case of metastatic disease. We report a case of a locally advanced GEJ adenocarcinoma with solitary resectable synchronous metastases at the jejunum and a good response to neoadjuvant therapy followed by esophagectomy with curative intention. CASE PRESENTATION: This is the case of a patient with poorly differentiated adenocarcinoma of the GEJ with synchronous metastases at the jejunum. The patient underwent extensive work-up including PET-CT. The metastases at the jejunum were completely resected during an initial staging laparoscopy and there was no evidence of further metastatic disease. The patient received chemotherapy and re-staging showed remarkable tumor response. Esophagectomy with curative intent was performed. Histopathology showed complete pathologic response after chemotherapy. Although our patient had a stage IV disease at presentation, he remained metastasis-free for a significant period of time, with no evidence of any distant recurrence during a follow-up of 16 months after esophagectomy. DISCUSSION AND CONCLUSIONS: Synchronous metastasis to the small bowel from an esophageal carcinoma is a rare entity. Routine PET-CT in addition to conventional CT may assist in more precise staging of a patient with resectable disease. Stage IV esophageal cancer with limited and resectable metastatic disease and good tumor response to oncological therapy may be considered for treatment with potentially curative intent.

Appendiceal perforation due to biliary stent migration in a neutropenic patient with lung cancer receiving chemotherapy: A case report.

The use of biliary stents has become a common and usually safe procedure. However, the migration of biliary stents is an uncommon but well-recognized event after endoscopic retrograde cholangiopancreatography. The migration of plastic stents usually does not result in complications and are spontaneously eliminated from the gastro-intestinal tract. Additionally, <1% of migrated stents result in intestinal perforation, which typically occurs at the duodenum. Chemotherapeutic agents may cause gastrointestinal toxicity and hematologic toxicity predisposing to neutropenic enterocolitis. The current study reports a patient with an unprecedented case of biliary stent migration resulting in appendiceal gangrene and perforation in a neutropenic patient under chemotherapy for metastatic small cell lung cancer.

Keyhole versus Sugarbaker techniques in parastomal hernia repair following ileal conduit urinary diversion: a retrospective nationwide cohort study.

BACKGROUND: Previous research on parastomal hernia repair following ileal conduit urinary diversion is limited. This nationwide cohort study aims to present the results of keyhole and Sugarbaker techniques in parastomal hernia repair in the setting of ileal conduit urinary diversion. METHOD: All patients in this cohort underwent primary elective parastomal hernia repair following ileal conduit urinary diversion in four university hospitals and one central hospital in Finland in 2007-2017. Retrospective clinical data were collected from patient registries to compare keyhole and Sugarbaker parastomal hernia repair techniques. The primary outcome was parastomal hernia recurrence during the follow-up from primary surgery to the last confirmed follow-up date of the patient. The secondary outcomes were reoperations during the follow-up and complication rate at 30 days' follow-up. RESULTS: The results of 28 hernioplasties were evaluated. The overall parastomal hernia recurrence rate was 18%, the re-operation rate was 14%, and the complication rate was 14% during the median follow-up time of 30 (21-64) months. Recurrence rates were 22% (4/18) after keyhole repair and 10% (1/10) after Sugarbaker repair. Re-operation rates referred to keyhole repair were 22% and Sugarbaker repair 0% during follow-up. The majority of reoperations were indicated by recurrence. Complication rates were 17% after keyhole and 10% after Sugarbaker repair during the 30 days' follow-up. CONCLUSION: The results of parastomal hernia repair in the setting of ileal conduits are below optimal in this nationwide cohort comparing keyhole to Sugarbaker repair in elective parastomal hernia repair. Nonetheless, the Sugarbaker technique should be further studied to confirm the encouraging results of this cohort in terms of recurrence.

Parastomal Hernia: A Retrospective Nationwide Cohort Study Comparing Different Techniques with Long-Term Follow-Up.

BACKGROUND: Parastomal hernia repair is a complex surgical procedure with high recurrence and complication rates. This retrospective nationwide cohort study presents the results of different parastomal hernia repair techniques in Finland. METHODS: All patients who underwent a primary end ostomy parastomal hernia repair in the nine participating hospitals during 2007-2017 were included in the study. The primary outcome measure was recurrence rate. Secondary outcomes were complications and re-operation rate. RESULTS: In total, 235 primary elective parastomal hernia repairs were performed in five university hospitals and four central hospitals in Finland during 2007-2017. The major techniques used were the Sugarbaker (38.8%), keyhole (16.3%), and sandwich techniques (15.4%). In addition, a specific intra-abdominal keyhole technique with a funnel-shaped mesh was utilized in 8.3% of the techniques; other parastomal hernia repair techniques were used in 21.3% of the cases. The median follow-up time was 39.0 months (0-146, SD 35.3). The recurrence rates after the keyhole, Sugarbaker, sandwich, specific funnel-shaped mesh, and other techniques were 35.9%, 21.5%, 13.5%, 15%, and 35.3%, respectively. The overall re-operation rate was 20.4%, while complications occurred in 26.3% of patients. CONCLUSION: The recurrence rate after parastomal hernia repair is unacceptable in this nationwide cohort study. As PSH repair volumes are low, further multinational, randomized controlled trials and hernia registry data are needed to improve the results.

Immediate effects of urgent reorganisation of emergency department-based treatment pathway in nonperforated appendicitis: a retrospective study.

BACKGROUND: Acute appendicitis is a global disease and a very common indication for emergency surgery worldwide. The need for hospital resources is therefore constantly high. The administration in Kanta-Häme Central Hospital, Southern Finland, called for an urgent reorganisation due to shortage of hospital beds at the department of general surgery. Postoperative treatment pathway of patients with nonperforated acute appendicitis was ordered to take place in the Emergency Department (ED). The aim of this study was to assess, whether this reorganisation was feasible and safe, i.e. did it affect the length of in-hospital stay (LOS) and the 30-day complication rate. METHODS: This is a retrospective pre- and post-intervention analysis. After the reorganisation, most patients with nonperforated appendicitis were followed postoperatively at the 24-h observation unit of the ED instead of surgical ward. Patients operated during the first 3 months after the reorganisation were compared to those operated during the 3 months before it. A case met inclusion criteria if there were no signs of appendiceal perforation during surgery. Exclusion criteria comprised age < 18 years and perforated disease. RESULTS: Appendicectomy was performed on 112 patients, of whom 62 were adults with nonperforated appendicitis. Twenty-seven of the included patients were treated before the reorganisation, and 35 after it. Twenty of the latter were followed only at the ED. Postoperative LOS decreased significantly after the reorganisation. Median postoperative time till discharge was 15.7 h for all patients after the reorganisation compared to 24.4 h before the reorganisation (standard error 6.2 h, 95% confidence interval 2.3-15.2 h, p < 0.01). There were no more complications in the group treated postoperatively in the ED. CONCLUSIONS: Early discharge of patients with nonperforated appendicitis after enforced urgent reorganisation of the treatment pathway in the ED observation unit is safe and feasible. Shifting the postoperative monitoring and the discharge policy of such patients to the ED - instead of the surgical ward - occurred in the majority of the cases after the reorganisation. This change may spare resources as in our series it resulted in a significantly shorter LOS without any increase in the 30-day complication rate.

Pericolic or paracolic? The right word in the right place for acute diverticulitis.

KEY POINT: • The term "pericolic" is wrongly used to describe an abscess adjacent to the colon in patients with acute diverticulitis. We explain why the proper term is the word "paracolic."

Index C-reactive protein predicts increased severity in acute sigmoid diverticulitis.

PURPOSE: Conservative management is successful in unperforated (Hinchey Ia) acute diverticulitis (AD) and also generally in local perforation or small abscesses (Hinchey Ib). A higher degree of radiological severity (Hinchey >Ib), ie, a larger abscess (>3-4 cm) or peritonitis, commonly requires percutaneous drainage or surgery. Retrospective studies show that high levels of C-reactive protein (CRP) distinguish Hinchey Ia from all cases of minor and major perforations (Hinchey >Ia). The current study aims to evaluate the usefulness of CRP in distinguishing AD with a higher degree of severity (Hinchey >Ib) from cases that can be treated noninvasively (Hinchey Ia/Ib). METHODS: Data from consecutive patients with AD were collected prospectively. All underwent computed tomography (CT). Index parameters obtained at the initial evaluation at the emergency unit were analyzed to assess the association with the outcome. The exclusion criteria comprised concomitant conditions that affected CRP baseline levels. RESULTS: Ninety-nine patients were analyzed. Eighty-eight had mild radiological grading (Hinchey Ia/Ib), and 11 had severe radiological grading (Hinchey >Ib) (median index CRP 80 mg/L vs 236 mg/L [P<0.001]). White blood cells, neutrophils/lymphocytes, serum creatinine, serum glucose, generalized peritonitis, generalized abdominal tenderness, urinary symptoms, and index CRP were related to severe disease. Index CRP was the only independent predictor for Hinchey >Ib (P=0.038). The optimal cutoff value calculated by receiver operating characteristic curve analysis was found to be 173 mg/L (sensitivity 90.9%, specificity 90.9%, P<0.001). All patients who underwent radiological drainage or surgery had an index CRP >173 mg/L and Hinchey >Ib. CONCLUSION: CRP levels >173 mg/L obtained at the initial evaluation at the emergency unit predict major acute complications in AD. These patients commonly require urgent percutaneous drainage or surgical management.

The Early C-reactive Protein Trend Does Not Have a Role in Monitoring Acute Diverticulitis Progression.

OBJECTIVE: To investigate the variation of the values of the serum inflammation markers during the hospital stay of patients with acute diverticulitis and to evaluate the role of their initial trend in the early determination of the disease resistance to conservative measures. PATIENTS AND METHODS: The electronic records of patients presenting with acute diverticulitis at the Oulu University Hospital, Finland during a 2-year period starting from December 2006 were retrospectively reviewed. Acute diverticulitis that was successfully treated conservatively was graded as mild. Severe disease was considered when a percutaneous or surgical intervention was necessitated during the same hospitalization or within the first month. Comparisons of the means of continuous variables were performed using the paired samples T test. RESULTS: One hundred and thirty-nine patients with mild acute diverticulitis had available data concerning the initial trends of the inflammation markers. The C-reactive protein (CRP) mean value showed a paradoxical significant increase in uncomplicated cases whereas the WBC count declined within the first 24 hours of hospitalization. Thereafter the CRP levels showed a significant daily decrease below the initial levels for the remainder of the in-hospital duration. The inflammation markers' initial trends in patients with severe disease did not change significantly. CONCLUSION: A rise in the CRP value during the first 24 hours of hospitalization should not be necessarily considered as a deterioration of the clinical status. This trend has no role in the early evaluation of the clinical progression of acute diverticulitis as it may mislead the clinician towards potential invasive overtreatment.

Ischemic Conditioning of the Stomach in the Prevention of Esophagogastric Anastomotic Leakage After Esophagectomy.

Esophagectomy with esophagogastric anastomosis is a major procedure, and its most feared complication is anastomotic leakage. Ischemic conditioning of the stomach is a method used with the aim of reducing the risk of leakage. It consists of partial gastric devascularization through embolization or laparoscopy followed by esophagectomy and anastomosis at a second stage, thus providing the time for the gastric conduit to adapt to the acute ischemia at the time of its formation. This review analyzes the information from all currently available experimental and clinical studies with the purpose of assessing the current role of the technique and to provide future recommendations.

The role of C-reactive protein in the prediction of the clinical severity of acute diverticulitis.

The aim of this study is to investigate the value of C-reactive protein (CRP) and of other laboratory parameters obtained during the initial evaluation of the patient in the prediction of the clinical severity of acute diverticulitis. The records of patients treated for acute diverticulitis at the Oulu University Hospital from December 2006 to December 2008 were retrospectively reviewed. Mild disease was defined when conservative treatment was successful. Severe acute diverticulitis was considered when percutaneous drainage of an abscess and/or surgery was necessary. From the 182 patients considered for analysis, 158 (87%) had mild disease, whereas 24 (13%) had severe. CRP (P = 0.034) and the Hinchey classification (P = 0.006) were shown to be independent risk factors for severe acute diverticulitis in the logistic regression analysis. The receiver operating characteristic curve showed that a CRP cutoff value of 170 mg/L significantly discriminated severe from mild diverticulitis (87.5% sensitivity, 91.1% specificity, area under the curve 0.942, P < 0.00001). CRP is a useful tool in the prediction of the clinical severity of acute diverticulitis. A mild episode is very likely in patients with CRP less than 170 mg/L. Those with higher CRP values have a greater probability to undergo surgical treatment or at least a percutaneous intervention.

Computed tomography-guided radiofrequency ablation for palliation of a painful supraclavicular soft-tissue metastasis invading the brachial plexus.

The present study describes a case of a painful supraclavicular soft-tissue metastasis of a skin melanoma invading the brachial plexus in a 38-year-old male. The patient was treated twice with radiofrequency ablation (RFA) under computed tomography (CT) guidance, which caused tumoral necrosis. The patient was originally referred with a 7-cm metastasis in the right supraclavicular fossa, which caused intractable pain and a degree of numbness. These symptoms were unresponsive to chemotherapy and radiotherapy and the pain was not controlled using narcotic analgesics. The lesion was treated with CT-guided RFA causing necrosis, relieving the pain and sparing the patient from using analgesics. The pain recurred 19 months thereafter and a CT scan revealed an 8-cm mass in the right supraclavicular space. The patient underwent repeat CT-guided RFA, which reduced the pain to a level that was controlled with minor oral analgesics. In conclusion, in this case of a painful supraclavicular soft-tissue metastasis invading the brachial plexus, which was intractable to chemotherapy and radiotherapy, RFA was feasible and offered substantial palliation of the symptoms, freedom from the use of narcotic analgesics and improvements to the quality of life.

Limits of infrainguinal bypass surgery for critical leg ischemia in high-risk patients (Finnvasc score 3-4).

BACKGROUND: The aim of the present study was to compare the early- and midterm outcomes after infrainguinal bypass surgery in the treatment of low- and high-risk patients with critical limb ischemia (CLI) (Finnvasc score 0-2 and 3-4, respectively), and to evaluate limits of infrainguinal bypass surgery in treatment of the latter group. METHODS: Two hundred seventy-four infrainguinal bypass procedures performed in 218 patients were retrospectively reviewed. The Finnvasc score (range: 0-4) was calculated by assigning one point to each of four preoperative risk factors, that is, coronary artery disease, diabetes, urgency of the procedure, and gangrene. Major outcome end points were survival, limb salvage, and amputation-free survival. RESULTS: Among 274 infrainguinal bypass procedures performed for CLI, 92 procedures (33.6%) were performed in patients with Finnvasc score 3-4. They had significantly lower leg salvage (at 3-year follow-up, 53.7 vs. 70.6%; log-rank: p = 0.004), survival (at 3-year follow-up, 49.7 vs. 69.7%; log-rank: p < 0.0001), and amputation-free survival (at 3-year follow-up, 27.7 vs. 53.1%; log-rank: p < 0.0001) compared with patients with Finnvasc score 0-2. Patients with Finnvasc score 3-4 and a preoperative serum creatinine level of >150 µmol/L had 1-year amputation-free survival of 12.5%, whereas patients with lower level of creatinine had 1-year amputation-free survival of 53.1% (p = 0.028). CONCLUSIONS: Infrainguinal bypass revascularization in CLI patients who present with Finnvasc score 3-4 can be considered at higher risk of poor intermediate outcome in terms of survival, leg salvage, and amputation-free survival. Poor outcome is particularly expected in patients with Finnvasc score 3-4 and renal failure. In this subgroup of patients, primary amputation should be considered.
