Three-year survival and distribution of lymph node metastases in gastric cancer following neoadjuvant chemotherapy: results from a European randomized clinical trial.

BACKGROUND: Adequate lymphadenectomy is an important step in gastrectomy for cancer, with a modified D2 lymphadenectomy being recommended for advanced gastric cancers. When assessing a novel technique for the treatment of gastric cancer, lymphadenectomy should be non-inferior. The aim of this study was to assess completeness of lymphadenectomy and distribution patterns between open total gastrectomy (OTG) and minimally invasive total gastrectomy (MITG) in the era of peri-operative chemotherapy. METHODS: This is a retrospective analysis of the STOMACH trial, a randomized clinical trial in thirteen hospitals in Europe. Patients were randomized between OTG and MITG for advanced gastric cancer after neoadjuvant chemotherapy. Three-year survival, number of resected lymph nodes, completeness of lymphadenectomy, and distribution patterns were examined. RESULTS: A total of 96 patients were included in this trial and randomized between OTG (49 patients) and MITG (47 patients). No difference in 3-year survival was observed, this was 57.1% in OTG group versus 46.8% in MITG group (P = 0.186). The mean number of examined lymph nodes per patient was 44.3 ± 16.7 in the OTG group and 40.7 ± 16.3 in the MITG group (P = 0.209). D2 lymphadenectomy of 71.4% in the OTG group and 74.5% in the MITG group was performed according to the surgeons; according to the pathologist compliance to D2 lymphadenectomy was 30% in the OTG group and 36% in the MITG group. Tier 2 lymph node metastases (stations 7-12) were observed in 19.6% in the OTG group versus 43.5% in the MITG group (P = 0.024). CONCLUSION: No difference in 3-year survival was observed between open and minimally invasive gastrectomy. No differences were observed for lymph node yield and type of lymphadenectomy. Adherence to D2 lymphadenectomy reported by the pathologist was markedly low.

Sarcopenia and Patient's Body Composition: New Morphometric Tools to Predict Clinical Outcome After Ivor Lewis Esophagectomy: a Multicenter Study.

BACKGROUND: The impact of preoperative body composition as independent predictor of prognosis for esophageal cancer patients after esophagectomy is still unclear. The aim of the study was to explore such a relationship. METHODS: This is a multicenter retrospective study from a prospectively maintained database. We enrolled consecutive patients who underwent Ivor-Lewis esophagectomy in four Italian high-volume centers from May 2014. Body composition parameters including total abdominal muscle area (TAMA), visceral fat area (VFA), and subcutaneous fat area (SFA) were determined based on CT images. Perioperative variables were systematically collected. RESULTS: After exclusions, 223 patients were enrolled and 24.2% had anastomotic leak (AL). Sixty-eight percent of patients were sarcopenic and were found to be more vulnerable in terms of postoperative 90-day mortality (p = 0.028). VFA/TAMA and VFA/SFA ratios demonstrated a linear correlation with the Clavien-Dindo classification (R = 0.311 and 0.239, respectively); patients with anastomotic leak (AL) had significantly higher VFA/TAMA (3.56 ± 1.86 vs. 2.75 ± 1.83, p = 0.003) and VFA/SFA (1.18 ± 0.68 vs. 0.87 ± 0.54, p = 0.002) ratios. No significant correlation was found between preoperative BMI and subsequent AL development (p = 0.159). Charlson comorbidity index correlated significantly with AL (p = 0.008): these patients had a significantly higher index (≥ 5). CONCLUSION: Analytical morphometric assessment represents a useful non-invasive tool for preoperative risk stratification. The concurrent association of sarcopenia and visceral obesity seems to be the best predictor of AL, far better than simple BMI evaluation, and potentially modifiable if targeted with prehabilitation programs.

A national survey on the current status of minimally invasive gastric practice on behalf of GIRCG.

Italian Research Group for Gastric Cancer (GIRCG), during the 2013 annual Consensus Conference to gastric cancer, stated that laparoscopic or robotic approach should be limited only to early gastric cancer (EGC) and no further guidelines were currently available. However, accumulated evidences, mainly from eastern experiences, have supported the application of minimally invasive surgery also for locally advanced gastric cancer (AGC). The aim of our study is to give a snapshot of current surgical propensity of expert Italian upper gastrointestinal surgeons in performing minimally invasive techniques for the treatment of gastric cancer in order to answer to the question if clinical practice overcome the recommendation. Experts in the field among the Italian Research Group for Gastric Cancer (GIRCG) were invited to join a web 30-item survey through a formal e-mail from January 1st, 2020, to June 31st, 2020. Responses were collected from 46 participants out of 100 upper gastrointestinal surgeons. Percentage of surgeons choosing a minimally invasive approach to treat early and advanced gastric cancer was similar. Additionally analyzing data from the centers involved, we obtained that the percentage of minimally invasive total and partial gastrectomies in advanced cases augmented with the increase of surgical procedures performed per year (p = 0.02 and p = 0.04 respectively). It is reasonable to assume that there is a widening of indications given by the current national guideline into clinical practice. Propensity of expert Italian upper gastrointestinal surgeons was to perform minimally invasive surgery not only for early but also for advanced gastric cancer. Of interest volume activity correlated with the propensity of surgeons to select a minimally invasive approach.

Relaparoscopy in the management of post-operative complications after minimally invasive gastrectomy for gastric cancer.

Laparoscopy has already been validated for treatment of early gastric cancer. Despite that, no data have been published about the possibility of a minimally invasive approach to surgical complications after primary laparoscopic surgery. In this multicentre study, we describe our experience in the management of complications following laparoscopic gastrectomy for gastric cancer. A chart review has been performed over data from 781 patients who underwent elective gastrectomy for gastric cancer between January 1996 and July 2020 in two high referral department of gastric surgery. A fully descriptive analysis was performed, considering all the demographic characteristics of patients, the type of primary procedure and the type of complication which required reoperation. Moreover, a logistic regression was designed to investigate if either the patients or the primary surgery characteristics could affect conversion rate during relaparoscopy. Fifty-one patients underwent reintervention after elective laparoscopic gastric surgery. Among patients who received a laparoscopic reintervention, 11 patients (34.3%) required a conversion to open surgery. Recovery outcomes were significantly better in patients who completed the reoperation through laparoscopy. Relaparoscopy is safe and effective for management of complications following laparoscopic gastric surgery and represent a useful tool both for re-exploration and treatment, in expert and skilled hands.

Post-esophagectomy tracheobronchoesophageal fistula: management and results of a tertiary referral center.

A tracheobronchoesophageal fistula (TBEF) is a rare but life-threatening complication after esophagectomy. The existing literature on TBEF management is limited and many previous recommendations are contradictory. We aimed to describe our series of TBEF after esophagectomy and compare it with other reported series. Patients who developed a TBEF after esophagectomy were identified retrospectively. Baseline and intraoperative characteristics, postoperative and TBEF details, treatments for TBEF, and main outcomes are described. A univariate analysis was performed to compare some of the analyzed variables with the overall sample. Finally, our results are compared with the previously described series. Altogether, 16 patients with TBEF (3.11%) were analyzed from 514 patients who received esophagectomies between January 2014 and February 2020. As a first treatment attempt, 14 (87.5%) were treated with surgery, one was treated conservatively, and one was treated endoscopically. Surgery both at a first or second treatment attempt achieved a survival rate of 62.5% and oral intake at discharge of 43.75%. Six patients died during their hospital stay (37.5%). The presence of an anastomotic leak showed a strong association with TBEF development (100% vs. 19.7%; OR 1.163, 95% CI 1.080-1.253, p = 0.000). In our experience, surgical treatment as the first approach for TBEF associated with anastomotic leak after esophagectomy obtained good results. However, there is an urgent need to elaborate treatment guidelines based on international consensus.

Health related quality of life following open versus minimally invasive total gastrectomy for cancer: Results from a randomized clinical trial.

INTRODUCTION: Minimally invasive techniques show improved short-term and comparable long-term outcomes compared to open techniques in the treatment of gastric cancer and improved survival has been seen with the implementation of multimodality treatment. Therefore, focus of research has shifted towards optimizing treatment regimens and improving quality of life. MATERIALS AND METHODS: A randomized trial was performed in thirteen hospitals in Europe. Patients were randomized between open total gastrectomy (OTG) or minimally invasive total gastrectomy (MITG) after neoadjuvant chemotherapy. This study investigated patient reported outcome measures (PROMs) on health-related quality of life (HRQoL) following OTG or MITG, using the Euro-Qol-5D (EQ-5D) and the European Organization for Research and Treatment of Cancer (EORTC) questionnaires, modules C30 and STO22. Due to multiple testing a p-value < 0.001 was deemed statistically significant. RESULTS: Between January 2015 and June 2018, 96 patients were included in this trial. Forty-nine patients were randomized to OTG and 47 to MITG. A response compliance of 80% was achieved for all PROMs. The EQ5D overall health score one year after surgery was 85 (60-90) in the open group and 68 (50-83.8) in the minimally invasive group (P = 0.049). The median EORTC-QLQ-C30 overall health score one year postoperatively was 83,3 (66,7-83,3) in the open group and 58,3 (35,4-66,7) in the minimally invasive group (P = 0.002). This was not statistically significant. CONCLUSION: No differences were observed between open total gastrectomy and minimally invasive total gastrectomy regarding HRQoL data, collected using the EQ-5D, EORTC QLQ-C30 and EORTC-QLQ-STO22 questionnaires.

Double layer stent for the treatment of leaks and fistula after upper gastrointestinal oncologic surgery: a retrospective study.

Anastomotic dehiscence is one of the most morbidity related and deadly complication after foregut oncologic surgery. The aim of the study is to evaluate the effectiveness of double layer stents (Niti-S™ Beta™ Esophageal Stent) in the management of dehiscences after upper gastrointestinal oncologic surgery. We retrospectively studied consecutive patients who underwent Niti-S™ Beta™ esophageal stent placement from June 2014 to September 2019 for the treatment of anastomotic leaks/fistula following esophagectomy or gastrectomy for cancer. Univariate two-sided logistic regression analysis was used to evaluate possible predictors of successful anastomotic leak/fistula closure. A total of 37 patients were studied and 75 stents were positioned in these patients during the endoscopic procedures. Effective leak/fistula closure was obtained in 23/37 (62.2%). No technical endoscopic failure or complications ensued during the placing of the devices. Regarding delayed complications, migration was observed in 17/75 (22.7%) procedures and stent leaking in 29/75 (38.6%). Three variables significantly favoured stent treatment failure, namely previous neoadjuvant therapy (OR 9.3, P = 0.01), fistula (instead of leak) (OR 6.5, P = 0.01), and stent leak (OR 17.0, P = 0.01). Placement of Beta Niti-S esophageal stent is a safe and effective method that could be considered for the management of leaks and fistula after upper gastrointestinal cancer. Crucial points in the management of post-surgical leaks with this technique are the prompt recognition of leaks and fistula, the prompt endoscopic/radiologic drain of collection and the choice of adequate size of the stent.

Circular versus linear stapling oesophagojejunostomy after laparoscopic total gastrectomy. A systematic review and meta-analysis.

BACKGROUND: To assess which anastomosis technique is the most appropriate after laparoscopic total gastrectomy, a systematic review with meta-analysis has been performed to evaluate safety and efficacy of the linear versus circular stapler performing the oesophagojejunostomy. METHODS: A systematic search was performed using the string: total AND gastrectomy AND (circular OR linear OR stapler). Extracted data were patients' number, gender, age, BMI, ASA Score, tumor stage. Outcomes were leakages, stenoses and bleedings, number of overall anastomotic complications, mortality, operative time, time to first flatus and diet resumption and length of stay of each group. A meta-analysis among the included studies was performed. A subgroup analysis, including the studies in which the Authors considered a single technique to perform each type of anastomosis (LS and CS), was performed. Meta-regression analyses were performed to assess if one or more demographic and clinical variables significantly impacted on the obtained results. RESULTS: 12 articles were included in the final analysis. A significant difference was observed in terms of "overall anastomotic complications" in favour of linear stapling (RD = 0.06, p = 0.01). No significant differences were observed in terms of postoperative complications anastomosis-related, even if a trend towards advantages of linear stapling have been found (stenosis: RD = 0.04, p = 0.06; bleeding: RD = 0.02, p = 0.05). However, all the study was retrospective and there was high heterogeneity among the studies. CONCLUSION: Linear stapler seems to be related with lesser number of complication if compared with circular stapler. However, further high-quality studies are needed to obtain definitive conclusions.

Diaphragmatic hernia after Ivor Lewis esophagectomy for cancer: a retrospective analysis of risk factors and post-repair outcomes.

BACKGROUND: Esophageal cancer surgery has historically been associated with high levels of postoperative morbidity and mortality. Post-esophagectomy diaphragmatic hernia (PEDH) represents a potentially life-threatening surgical complication, with incidence and risk factors not clearly demonstrated. This study evaluates presenting characteristics and repair outcomes in PEDH after Ivor Lewis esophagectomy for cancer. METHODS: All consecutive patients who underwent esophageal cancer surgery between March 1997 and April 2018 at two high-volume centers were included. The patients underwent Ivor Lewis esophagectomy and were managed according to a standardized follow-up care plan. The primary outcomes included PEDH incidence, risk factor identification, and surgical results after hernia repair. Patient characteristics and perioperative data were collected and a multivariate analysis was performed to identify risk factors for PEDH. RESULTS: A total of 414 patients were enrolled and 22 (5.3%) were diagnosed with PEDH during a median follow-up period of 16 (range, 6-177) months. All patients underwent surgical repair and 16 (73%) required treatment within 24 hours. PEDH repair was mainly performed through a laparoscopic approach (77.3%), with an overall postoperative morbidity of 22.7% and one mortality case. The median length of hospital stay was 6 (range, 2-95) days, and no early recurrences were observed, although three (13.6%) cases relapsed over a median follow-up of 10.1 months after hernia repair. Univariate analysis demonstrated a statistically significant association between PEDH and neoadjuvant chemoradiotherapy (P=0.016), pathological complete response (P=0.001), and lymph node harvest (P=0.024). On the other hand, multivariate analysis identified pathological complete response [3.616 (1.384-9.449), P=0.009] and lymph node harvest [3.029 (1.140-8.049), P=0.026] as the independent risk factors for developing PEDH. CONCLUSIONS: PEDH represents a relevant surgical complication after Ivor Lewis esophagectomy for cancer, including a 5.3% incidence and requiring surgical repair. Pathological complete response and lymph node harvest were found to be independent risk factors for PEDH, independently of the esophagectomy technique.

Does Pathological Stage and Nodal Involvement Influence Long Term Oncological Outcomes after CROSS Regimen for Adenocarcinoma of the Esophagogastric Junction? A Multicenter Retrospective Analysis.

Background:After the results reported by the "Chemoradiotherapy for esophageal Cancer Followed by Surgery Study" (CROSS) trial, neo-adjuvant chemoradiotherapy became the standard treatment for locally advanced cancers of esophagus and gastroesophageal junction (GEJ). Excellent results were reported for squamocellular carcinomas (SCCs). Since the advent of the CROSS regimen, the results of surgery for esophageal adenocarcinomas (EAC) have cast some doubts about its efficacy on overall survival (OS) even in the presence of local response. This study evaluated the relation between pathological (yp) stage after CROSS regimen followed by surgery for adenocarcinoma of cardia and overall (OS) and disease-free survival (DFS). Sites of relapse after surgery were also analyzed. Methods: Patients submitted to the CROSS regimen for locally advanced EAC of the cardia followed by transthoracic esophagectomy were analyzed. Actuarial OS and DFS were analyzed and stratified according to yp stage. The site of relapse, distal and local, was also analyzed. Results: The study included 132 patients. The 50-month OS and DFS were 45% and 6.7%, respectively. No differences emerged analyzing OS according to yp stage. Time to relapse was significantly longer for yp Stage I and II, and for yp N0, compared with yp N+. Recurrence occurred in 48 cases (36.3%) with a 9 months median time to relapse. Local and distal relapse were 10 (7.5%) and 38 (28.7%) cases, respectively (p ≦ 0.001). Conclusions: Pathological stage after CROSS regimen does not relate to OS and DFS. Time to recurrence is significantly longer for yp Stages I and II and ypN0. Chemoradiotherapy in a neoadjuvant setting may influence the site of relapse, significantly reducing local recurrences.

Application of ERAS protocol in esophagectomy: a national survey among Italian centers performing esophageal surgery.

The application of enhanced recovery after surgery guidelines for esophageal surgery in different units remains unclear. This survey intended to investigate how such protocol is applied among Italian esophageal surgery units. A survey with 40 questions was mailed to Italian centers that performed at least 10 esophagectomies per year. It included questions about the type of hospital and unit and pre-, intra- and post-operative items. Difficulties encountered were investigated. Thirteen (65%) centers answered the survey, and all met the minimal safety requirements, e.g., the presence of intensive care units and 24-h on-call operative endoscopy and radiology facilities. Fifty percent of esophagectomies with a minimally invasive approach were performed in 84.6% of the centers. Regarding pre-operative items, the highest scores were for the application of nutritional support, dysphagia palliation and presence of a multidisciplinary tumor board, whereas the lowest score was for the use of immunonutrition. Regarding intra-operative items, hypothermia prevention and the use of goal-directed fluid therapy and volatile anesthesia were diffusely adopted, whereas the rate of using abdominal drains was high. Regarding post-operative items, nausea prevention, multimodal analgesia and early mobilization were applied frequently, whereas the use of nasogastric tubes and regular transfer to intensive care units was diffused. The primary barriers in enhanced recovery after surgery protocol application were resistance and a lack of paramedic personnel. This survey's results highlight the efforts undertaken by several centers to apply enhanced recovery after surgery philosophy and in this regard, demonstrate a good standing in Italy.

Enhanced recovery after surgery in colon and rectal surgery: identification of predictive variables of failure in a monocentric series including 733 patients.

To identify factors associated with early deviation and delayed discharge within an Enhanced Recovery after Surgery (ERAS) pathway. This is a retrospective review of prospectively collected data of consecutive patients who underwent laparoscopic or open colorectal surgery and managed with a standardized ERAS pathway between April 2015 and October 2018. ERAS items were assessed within 48 h after surgery. Patients with early complications were excluded. The influence of factors on length of stay was calculated by univariate and multivariate analysis. A binary logistic regression was used to model a predicting score. Seven hundred and thirty-three patients met the inclusion criteria. Multivariate analysis showed that age ≥ 75 years (P = 0.02), ASA score ≥ 3 (P = 0.03), open surgery or conversion to open (P = 0.001), non-compliance with the intra-operative balanced fluid therapy (P = 0.049), failure to early removal of the urinary catheter (P = 0.001), to discontinue IV fluid (P = 0.02) and to early mobilization (P = 0.001) were independently associated with ERAS failure. The generated score had a specificity of 84% and a positive predictive value of 72%. Patients who would have a length of stay longer than the median for each surgical procedure were properly identified (Area under ROC Curve = 0.753, P < 0.001). The delayed discharge could be predicted at 48 h from the intervention. The ability of the model to weight the specific role of each statistically significant variable might be a useful tool to identify the most frail patients.

Open versus minimally invasive total gastrectomy after neoadjuvant chemotherapy: results of a European randomized trial.

BACKGROUND: Surgical resection with adequate lymphadenectomy is regarded the only curative option for gastric cancer. Regarding minimally invasive techniques, mainly Asian studies showed comparable oncological and short-term postoperative outcomes. The incidence of gastric cancer is lower in the Western population and patients often present with more advanced stages of disease. Therefore, the reproducibility of these Asian results in the Western population remains to be investigated. METHODS: A randomized trial was performed in thirteen hospitals in Europe. Patients with an indication for total gastrectomy who received neoadjuvant chemotherapy were eligible for inclusion and randomized between open total gastrectomy (OTG) or minimally invasive total gastrectomy (MITG). Primary outcome was oncological safety, measured as the number of resected lymph nodes and radicality. Secondary outcomes were postoperative complications, recovery and 1-year survival. RESULTS: Between January 2015 and June 2018, 96 patients were included in this trial. Forty-nine patients were randomized to OTG and 47 to MITG. The mean number of resected lymph nodes was 43.4 ± 17.3 in OTG and 41.7 ± 16.1 in MITG (p = 0.612). Forty-eight patients in the OTG group had a R0 resection and 44 patients in the MITG group (p = 0.617). One-year survival was 90.4% in OTG and 85.5% in MITG (p = 0.701). No significant differences were found regarding postoperative complications and recovery. CONCLUSION: These findings provide evidence that MITG after neoadjuvant therapy is not inferior regarding oncological quality of resection in comparison to OTG in Western patients with resectable gastric cancer. In addition, no differences in postoperative complications and recovery were seen.

Impact of COVID-19 outbreak on esophageal cancer surgery in Northern Italy: lessons learned from a multicentric snapshot.

Coronavirus Disease-19 (COVID-19) outbreak has significantly burdened healthcare systems worldwide, leading to reorganization of healthcare services and reallocation of resources. The Italian Society for Study of Esophageal Diseases (SISME) conducted a national survey to evaluate changes in esophageal cancer management in a region severely struck by COVID-19 pandemic. A web-based questionnaire (26 items) was sent to 12 SISME units. Short-term outcomes of esophageal resections performed during the lockdown were compared with those achieved in the same period of 2019. Six (50%) centers had significant restrictions in their activity. However, overall number of resections did not decrease compared to 2019, while a higher rate of open esophageal resections was observed (40 vs. 21.7%; P = 0.034). Surgery was delayed in 24 (36.9%) patients in 6 (50%) centers, mostly due to shortage of anesthesiologists, and occupation of intensive care unit beds from intubated COVID-19 patients. Indications for neoadjuvant chemo (radio) therapy were extended in 14% of patients. Separate COVID-19 hospital pathways were active in 11 (91.7%) units. COVID-19 screening protocols included nasopharyngeal swab in 91.7%, chest computed tomography scan in 8.3% and selective use of lung ultrasound in 75% of units. Postoperative interstitial pneumonia occurred in 1 (1.5%) patient. Recovery from COVID-19 pandemic was characterized by screening of patients in all units, and follow-up outpatient visits in only 33% of units. This survey shows that clinical strategies differed considerably among the 12 SISME centers. Evidence-based guidelines are needed to support the surgical esophageal community and to standardize clinical practice in case of further pandemics.

Re-laparoscopy in the treatment of anastomotic leak following laparoscopic right colectomy with intracorporeal anastomosis.

BACKGROUND: Anastomotic leak still represents the most feared surgical complication following colorectal resection and is associated with high morbidity and mortality rates. The aim of this study is to assess the feasibility and safety of laparoscopic reoperation for symptomatic anastomotic leak (AL) after laparoscopic right colectomy with mechanical intracorporeal anastomosis (IA). METHODS: From January 2012 to December 2019, 428 consecutive laparoscopic right colectomy with IA were performed. Overall symptomatic AL rate requiring reoperation was 5.8% (26/428). Data on patient demographics as well as operative findings, time elapsed from primary surgery and from the onset of symptoms of anastomotic leak, time and duration of re-laparoscopy, ICU stay, morbidity, mortality rate, length of hospital stay and readmission, were all retrospectively reviewed. RESULTS: Laparoscopic approach was attempted in 23 (88.4%) hemodynamically stable patients. Conversion rate was 21.4%. Reasons for conversion were gross fecal peritonitis (n = 2), colonic ischemia (n = 1), severe bowel distension (n = 2). Eighteen (78.2%) patients underwent successfully laparoscopic (LPS) reoperation. A repair of the anastomotic defect was done in 11 (61.1%) patients, while in 7 patients the intracorporeal mechanical anastomosis was refashioned. A diverting ileostomy was done in 22.2% of cases (n = 4). A second reoperation for leak persistence was necessary in two cases (11.1%). Median (range) length of postoperative hospital stay from re-laparoscopy was 15.5 (9-53) days. Overall morbidity rate was 38.7%. Mortality rate was 5.5% (n = 1) CONCLUSION: laparoscopic re-intervention for the treatment of anastomotic leak following LPS right colectomy with intracorporeal anastomosis in hemodynamically stable and highly selected patients in the experienced hands of dedicated laparoscopic surgeons, is a safe option with acceptable morbidity and mortality rate.

Perfusion speed of indocyanine green in the stomach before tubulization is an objective and useful parameter to evaluate gastric microcirculation during Ivor-Lewis esophagectomy.

BACKGROUND: Anastomotic leakage (AL) during Ivor-Lewis esophagectomy (ILE), owing to gastric conduit (GC) ischemia, is a serious complication. Measurement parameters during intraoperative ICG fluorescence angiography (ICG-FA) are unclear. We aimed to identify objective ICG-FA parameters associated with AL. STUDY DESIGN: Patients > 18 years with an indication for ILE were enrolled. ICG-FA was performed at the abdominal and thoracic stage, and data, such as time of fluorescence appearance, speed of ICG perfusion, quality of GC perfusion (good, poor, ischemic), blood pressure, baseline patient characteristics, GC dimensions, and other intraoperative parameters were collected. On postoperative day 4 to 6, Gastrografin swallow radiography was performed. AL development was classified based on the Clavien-Dindo and SISG severity classifications. Univariate analysis with a 95% confidence level (p < 0.05) was performed. Factors with p < 0.05 were included in the multivariate analysis. RESULTS: 100 patients were enrolled. During ICG-FA, evaluation of subjective perfusion was a very specific test (94.1%) with good negative predictive value (NPV 71.9%, p 0.034), but not powerful enough to detect patients at risk of leak (sensibility 21.8%, PPV 63.6%). The GC perfusion speed (cm/s) after gastric vascular isolation and before tubulization showed a significant association with AL (p < 0.003). Median arterial blood pressure in the thoracic stage (p < 0.001) or use of inotropic (p < 0.033) was associated with AL development. CONCLUSION: GC perfusion speed at ICG-FA is an objective parameter that could predict AL risk. Other results emphasize the importance of the microcirculation in the development of AL.

A large anastomotic leakage after esophageal surgery treated with endoluminal vacuum-assisted closure: a case report.

The treatment of anastomotic post-esophagectomy leaks and fistula is challenging. Endoluminal vacuum-assisted closure (EVAC) is an emerging technique that employs negative pressure wound therapy to treat anastomotic leaks endoscopically. Esosponge is specifically designed for esophageal EVAC therapy. We report on a 49-year-old woman who underwent a totally mini-invasive Ivor-Lewis esophagectomy and developed a giant postoperative leak with a complex pleural collection, but she was not fit for surgical re-intervention. The patient healed almost completely after 14 exchange sessions of Esosponge over 35 days.

Treatment of Epiphrenic Diverticulum: How I Do It.

Epiphrenic diverticulum is a rare esophageal disorder occurring as an outpouching of mucosa and submucosa through the muscular layers, within 10 cm above the cardia. As the majority of epiphrenic diverticula are asymptomatic, the real incidence varies because of a considerable number of cases detected incidentally during radiographic or endoscopic evaluation. Traditionally, the operation was performed through a left thoracotomy approach and the diverticulectomy was completed with esophago-cardial myotomy and a Belsey Mark IV fundoplication. Laparoscopy offers many advantages in the treatment such as the possibility of extension of the myotomy from the lower esophagus through the stomach and the concomitant antireflux procedure to avoid postoperative reflux. The abdominal approach is also more comfortable for the patients and, as there is no need for transthoracic drains, is more tolerated in terms of postoperative pain. In this article, we do review our technique with all the steps of the operation illustrated by intraoperative pictures.
