RESUMEN

The downstream effects on healthcare delivery during the initial wave of the COVID-19 pandemic remain unclear. The purpose of this study was to determine how the healthcare environment surrounding the pandemic affected the oncologic care of patients diagnosed with esophageal cancer. This was a retrospective cohort study evaluating patients in the National Cancer Database (2019-2020). Patients with esophageal cancer diagnoses were divided into pre-pandemic (2019) and pandemic (2020) groups. Patient demographics, cancer-related variables, and treatment modalities were compared. Among 26,231 esophageal cancer patients, 14,024 patients (53.5%) were in the pre-pandemic cohort and 12,207 (46.5%) were in the pandemic cohort. After controlling for demographics, patients diagnosed during the pandemic were more likely to have poorly differentiated tumors (odds ratio [OR] 1.24, 95% confidence interval [CI] 1.08-1.42), pathologic T3 disease compared to T1 (OR 1.25, 95% CI 1.02-1.53), positive lymph nodes on pathology (OR 1.36, 95% CI 1.14-1.64), and to be pathologic stage IV (OR 1.51, 95% CI 1.29-1.76). After controlling for oncologic characteristics, patients diagnosed during the pandemic were more likely to require at least two courses of systemic therapy (OR 1.78, 95% CI 1.48-2.14) and to be offered palliative care (OR 1.13, 95% CI 1.04-1.22). While these patients were offered curative therapy at lower rates, this became non-significant after risk-adjustment (p = .15). The pandemic healthcare environment was associated with significantly increased risk-adjusted rates of patients presenting with advanced esophageal cancer. While this led to significant differences in treatment, most of these differences became non-significant after controlling for oncologic factors.

RESUMEN

Resectable cholangiocarcinoma (CCA) arising from the middle of the extrahepatic biliary tree has historically been classified as perihilar or distal CCA, depending on the operation contemplated or performed, namely the associated hepatectomy or pancreaticoduodenectomy, respectively. Segmental bile duct resection is a less invasive alternative for select patients harboring true middle extrahepatic CCA (MCC). A small, yet growing body of literature has emerged detailing institutional experiences with bile duct resection versus pancreaticoduodenectomy or concomitant hepatectomy for MCC. Herein, we provide a brief overview of the epidemiology, preoperative evaluation, and emerging systemic therapies for MCC, and narratively review the existing work comparing segmental resection with pancreaticoduodenectomy or less commonly, hepatectomy, for MCC, with emphasis on the surgical management and oncologic implications of the approach used.

RESUMEN

BACKGROUND: Benign anastomotic stricture is a recognized complication following esophagectomy. Laparoscopic gastric ischemic preconditioning (LGIP) prior to esophagectomy has been associated with decreased anastomotic leak rates; however, its effect on stricture and the need for subsequent endoscopic intervention is not well studied. METHODS: This was a case-control study at an academic medical center using consecutive patients undergoing oncologic esophagectomies (July 2012-July 2022). Our institution initiated an LGIP protocol on 1 January 2021. The primary outcome was the occurrence of stricture within 1 year of esophagectomy, while secondary outcomes were stricture severity and frequency of interventions within the 6 months following stricture. Bivariable comparisons were performed using Chi-square, Fisher's exact, or Mann-Whitney U tests. Multivariable regression controlling for confounders was performed to generate risk-adjust odds ratios and to identify the independent effect of LGIP. RESULTS: Of 253 esophagectomies, 42 (16.6%) underwent LGIP prior to esophagectomy. There were 45 (17.7%) anastomotic strictures requiring endoscopic intervention, including three patients who underwent LGIP and 42 who did not. Median time to stricture was 144 days. Those who underwent LGIP were significantly less likely to develop anastomotic stricture (7.1% vs. 19.9%; p = 0.048). After controlling for confounders, this difference was no longer significant (odds ratio 0.46, 95% confidence interval 0.14-1.82; p = 0.29). Of those who developed stricture, there was a trend toward less severe strictures and decreased need for endoscopic dilation in the LGIP group (all p < 0.20). CONCLUSION: LGIP may reduce the rate and severity of symptomatic anastomotic stricture following esophagectomy. A multi-institutional trial evaluating the effect of LGIP on stricture and other anastomotic complications is warranted.

RESUMEN

BACKGROUND: The robotic platform is increasingly being utilized in pancreatic surgery, yet its overall merits and putative advantages remain to be adjudicated. We hypothesize that the benefits of minimally invasive pancreatic surgery are maximized in pancreatic benign and premalignant disease, in the setting of friable pancreatic tissue and small pancreatic duct. METHODS: Retrospective analysis of our prospectively maintained pancreatic database of all consecutive patients who underwent pancreaticoduodenectomy (PD) for benign or premalignant conditions between 2010 and 2020. Peri-operative outcomes and long-term complications were compared between robotic pancreaticoduodenectomy (RPD) and open pancreaticoduodenectomy (OPD). RESULTS: One hundred and eighty eight (n = 188) patients met our inclusion criteria, of which 68 were OPD and 120 RPD. Malignant histologies were excluded. There were only minor differences in baseline characteristics between the two groups. Post-operative merits of the RPD included lower clinically relevant post-operative pancreatic fistula 10 (8.3%) vs 24 (35.3%), p < 0.001, fewer surgical site infections; 9 (7.5%) vs 11 (16.2%), p = 0.024, shorter operative time, greater lymph node yield; 29 (IQR 21, 38) vs 21 (IQR 13, 34), p = 0.001, and lower 90 days mortality; 1 (0.8%) vs 4 (5.9%), p = 0.039. Rates of long-term complications were similar, exception made for a higher occurrence of small bowel obstruction (SBO) 2 (1.7%) vs 4 (5.9%), p = 0.031 and need for surgical intervention for SBO 0 (0.0%) vs 2 (2.9%), p = 0.019 in the OPD group. CONCLUSION: Our study suggests that RPD benefits include lower 90-day mortality, shorter LOS, and lower rates of selected complications compared to open pancreaticoduodenectomy.

RESUMEN

BACKGROUND: Adjuvant chemotherapy and/or chemoradiation [chemo(radiation)] is considered the standard of care for resected patients with pancreatic adenocarcinoma. However, invasive carcinoma arising from an intraductal papillary mucinous neoplasm (IPMN) seems to have different biologic behavior and prognosis. Retrospective data suggest a survival benefit of adjuvant chemo(radiation) for resected invasive IPMNs with metastatic nodal disease; however, it is unclear whether this remains valid for node-negative patients. PATIENTS AND METHODS: To compare the outcome of patients with invasive IPMNs who received adjuvant chemo(radiation) with that of those treated with surgery alone, we queried the National Cancer Database regarding data of patients who underwent pancreatic resection for invasive IPMN between 2006 and 2015. A propensity score analysis was conducted to balance covariates between treatment groups. RESULTS: For the study, 492 patients were eligible, of whom 267 (54.3%) received adjuvant chemo(radiation). Estimated 1- and 3-year overall survival rates were 88.9% and 73.5% versus 93.2% and 72.8% for patients who did or did not receive adjuvant chemo(radiation), respectively. Among patients with negative nodal stage, there was no difference in overall survival between patients who received versus patients who did not receive adjuvant chemo(radiation) (P = 0.973). In contrast, among patients with positive nodal disease, those who received adjuvant chemo(radiation) had significantly better OS compared with those who did not (P = 0.001). CONCLUSIONS: In patients with resected invasive IPMNs, adjuvant chemo(radiation) was associated with significantly improved overall survival only in presence of nodal metastases. This finding can help clinicians to select adjuvant treatment in a patient-tailored fashion.

RESUMEN

BACKGROUND: Endophytic submucosal masses at anatomically difficult locations such as lesser curve of the stomach, juxta-gastroesophageal junction and duodenum are challenging to resect laparoscopically due to proximity of vital structures and difficulty to visualise them. To overcome these limitations, we describe a technique of endoscopic tattooing with indocyanine green (ICG) injection into the lesion allowing easy identification and oncological resection in a minimally invasive manner. PATIENTS AND METHODS: The technique of endoscopic tattooing of the lesion and robotic transgastric eversion resection technique is described in patients with gastrointestinal tumours at difficult anatomical location. RESULTS: Gastric gastrointestinal stromal tumours at the lesser curve (n = 3) and gastroesophageal junction (n = 1) were resected using this technique successfully. CONCLUSION: The use of intraoperative ICG tattooing of endophytic submucosal lesions at difficult locations can facilitate minimally invasive oncologic resection. This technique allows the surgeon to be more comfortable to approach complex lesions safely to improve patient outcomes.

RESUMEN

BACKGROUND: Colectomy is one of the most common major abdominal procedures performed in the USA. A better understanding of risk factors and the effect of operative approach on adverse postoperative outcomes may significantly improve quality of care. METHODS: Adult patients with a primary diagnosis of colon cancer undergoing colectomy were selected from the National Surgical Quality Improvement Program 2013-2015 targeted colectomy database. Patients were stratified into five groups based on specific operative approach. Univariate and multivariate analyses were used to compare the five groups and identify risk factors for 30-day anastomotic leak, readmission, and mortality. RESULTS: In total, 25,097 patients were included in the study, with a 3.32% anastomotic leak rate, 1.20% mortality rate, and 9.57% readmission rate. After adjusting for other factors, open surgery and conversion to open significantly increased the odds for leak, mortality, and readmission compared to laparoscopy. Additionally, smoking and chemotherapy increased the risk for leak and readmission, while total resection was associated with increased mortality and leak. CONCLUSIONS: Operative approach and several other potentially modifiable perioperative factors have a significant impact on risk for adverse postoperative outcomes following colectomy. To improve quality of care for these patients, efforts should be made to identify and minimize the influence of such risk factors.

RESUMEN

BACKGROUND: Minimally invasive esophagectomy (MIE) is gaining increasing popularity in the treatment of esophageal cancer. In fact, while surgical and oncologic outcomes are not inferior to those achieved through a traditional open approach, patients undergoing MIE benefit from shorter length of stay, lesser pain and prompter recovery. This technique is, however, highly challenging, and the development of a MIE program, even in the setting of a tertiary center, requires time and progressive honing of surgical skills. METHODS: We use a minimally invasive Ivor Lewis approach. The abdominal phase of the procedure includes complete celiac lymphadenectomy and tubularization of the stomach, which will constitute the neo-esophagus. The video-assisted thoracoscopic surgery portion of the operation takes place in left lateral decubitus and allows for optimal thoracic lymphadenectomy and anastomosis. RESULTS: From October 2011 to January 2015, we treated 52 patients with the above-described procedure. The evolution of our anastomotic technique included a first group of circular stapled anastomosis with Orvil™ and 3.5-mm EEA™ (n = 16 patients), subsequently abandoned in favor of a linear anastomosis (n = 12), before going back to the Orvil™ coupled with 4.8-mm EEA™ (n = 22) in more recent times. There were also an additional two anastomoses that did not fall under any of these categories. We experienced two postoperative deaths. The overall leak rate was 14%, but fell down to 4% in the last group. Median LOS was 9 days. Lymph node retrieval was adequate throughout the whole series. CONCLUSIONS: Developing a MIE program requires a significant learning curve before the results plateau. Only once a technique of choice is refined and mastered, the advantages granted by MIE become apparent.

RESUMEN

BACKGROUND: The laparoscopic approach for repair of giant and/or recurrent paraesophageal hernias (PEH) is challenging, due to limited access to the dissection of the hernia sac into the proximal mediastinum and esophageal mobilization through the diaphragmatic hiatus. An esophageal lengthening procedure is often necessary, due to the difficulty in obtaining adequate intra-abdominal esophageal length. We, therefore, developed a VATS and laparoscopic technique, which allows for safe and extensive thoracic dissection and intra-abdominal gastric fixation and cruroplasty, yet preserving the benefits of minimally invasive surgery. METHODS: We use a standard VATS approach. The hernia sac, optimally visualized, is dissected posteriorly from the thoracic aorta, inferiorly from its diaphragmatic attachments, anteriorly from the pericardium, and laterally from the mediastinal pleura. The esophagus is completely mobilized up to the aortic arch, and the anterior vagus nerve is released from its bronchial branches. The hernia sac is then opened, dissected, and completely removed. The hernia content is then reduced into the abdomen laparoscopically, the short gastric vessels are divided and the gastric fundus is completely mobilized. The hiatus is closed with interrupted sutures, and the cruroplasty is buttressed with a biological mesh. A floppy Nissen or a partial fundoplication and a gastropexy are done for reflux control and gastric fixation. RESULTS: From January 2012 to January 2014, we treated 18 patients (7 with type III PEH and 11 with type IV) with the above-described procedure. Six patients had previous history of antireflux surgery. We performed a planned laparotomy instead of laparoscopy in two patients, who needed concurrent repair of complex incisional hernias. We did not need esophageal lengthening procedures, nor experienced damages to thoracic structures in any patient. CONCLUSIONS: Our newly developed surgical approach has proven to be safe and feasible. This technique represents a good option for treatment of giant and complicated PEH.

RESUMEN

BACKGROUND: Cardiothoracic surgeons and general surgeons (including surgical oncologists) perform most esophagectomies. The purpose of this study was to explore whether specialty-driven differences in surgical techniques and the use of minimally invasive surgical approaches exist and are associated with postoperative outcomes after esophagectomy. METHODS: This was a retrospective review of the American College of Surgeons National Surgical Quality Improvement Program esophagectomy-targeted participant user file (2016-2018). Patients who underwent esophagectomy were sorted into cardiothoracic and general surgeon cohorts based on surgeon specialty. Perioperative characteristics and postoperative outcomes were compared using the χ2 analysis or independent t test. Multivariable logistic regression controlling for perioperative variables was performed to generate risk-adjusted rates of postoperative outcomes compared by surgical specialty. RESULTS: Of 3,247 patients included, 1,792 (55.2%) underwent esophagectomy by cardiothoracic surgeons and 1,455 (44.5%) by general surgeons as the primary surgeon. Cardiothoracic surgeons were more likely to use traditional minimally invasive surgical (P = .0004) or open approaches (P < .0001) and less likely to use robotic (P = .04) or a hybrid robotic and traditional approaches (P < .0001). Cardiothoracic surgeons performed more Ivor Lewis esophagectomies and fewer transhiatal and McKeown esophagectomies (P < .0001). After risk adjustment, there were no differences in rates of postesophagectomy complications, such as anastomotic leaks or positive margins, between cardiothoracic surgeons and general surgeons (all P > .05). However, cardiothoracic surgeons were more likely than general surgeons to treat anastomotic leaks with surgery rather than procedural interventions (odds ratio = 1.76; 95% confidence interval, 1.24-2.52). CONCLUSION: Cardiothoracic surgeons and general surgeons use minimally invasive surgical subtypes differently when performing esophagectomy. However, there were no risk-adjusted differences in postoperative complications when compared by surgical subspecialty. Esophagectomy is being performed safely by surgeons with different specialties and training pathways.

RESUMEN

Poorly differentiated esophageal adenocarcinoma (PDEAC) has a dismal prognosis. Glypican-1(GPC-1) is known to be upregulated in several cancer types in contrast to healthy tissues, rendering it as a biomarker. Nevertheless, the potential therapeutic targeting of GPC-1 has not been explored in PDEAC. There is accumulating evidence that GPC-1, via upregulation of PI3K/Akt/ERK signaling, plays a crucial role in the progression and chemoresistance in cancer. Pictilisib, a class I pan PI3K inhibitor, has shown promising antitumor results in clinical trials, however, has not gained widespread success due to acquired drug resistance. This study investigated the role of GPC-1 in chemo-resistant PDEAC and appraises the impact of targeted silencing of GPC-1 on the antitumor effects of Pictilisib in PDEAC cell lines. Immunohistochemistry assays in PDEAC tissue specimens demonstrated a pronounced intensity of staining with GPC-1. Upregulation of GPC-1 was found to be correlated with advanced stage and poor prognosis. In-vitro studies examined the influence of GPC-1 knockdown and Pictilisib, both as individual agents and in combination, on cytotoxicity, cell cycle distribution, apoptosis, and gene expression profiles. Silencing GPC-1 alone showed significantly reduced cell viability, migration, colony formation, epithelial-mesenchymal transition, and stemness in PDEAC cells. Significantly, knockdown of GPC-1 combined with low-dose Pictilisib led to enhancement of cytotoxicity, cell cycle arrest, and apoptosis in ESO-26 and OE-33 cells. In the xenograft mouse model, the combination of Pictilisib and GPC-1 knockdown exhibited synergy. These findings suggest that GPC-1 represents a promising target to augment chemosensitivity in esophageal adenocarcinoma.

RESUMEN

BACKGROUND: The aim of this study was to evaluate the feasibility of a totally stapled gastrojejunal anastomosis performed using one transabdominal 12-mm trocar and a gastroscope in a porcine model. METHODS: The procedure was carried out on six domestic pigs weighing 45 kg using a hybrid technique with a gastroscope and a 12-mm Hasson trocar, positioned in the left hypochondrium. At the end of the procedure a mechanical circular 21-mm gastrojejunal anastomosis was performed by inserting the stapler through a small gastrotomy after enlarging the trocar incision. RESULTS: In all six cases the procedure was completed through a single 3 cm abdominal incision and without complications. The mean operating time was 2 h, and endoscopic investigation showed that the anastomoses were intact, patent, and airtight. CONCLUSIONS: Totally stapled gastrojejunal anastomosis using a hybrid NOTES-single 12-mm trocar approach is a feasible procedure in the porcine model. Further survival studies are warranted, particularly to evaluate the functional results of this procedure.

RESUMEN

BACKGROUND: Natural orifice transluminal endoscopic surgery (NOTES), a new frontier of minimally invasive surgery, uses the body's natural orifices to create an access for surgical procedures. This study aimed to verify the technical feasibility of ileorectal bypass performed entirely through a transanal access. METHODS: The procedure was performed on 10 domestic pigs, after which they were killed. A transanal endoscopic microsurgery (TEM) device and endoscopic and laparoscopic instruments were used. RESULTS: The findings demonstrated that an ileorectal bypass through a transanal access is feasible. The principal steps of a standardized transanal procedure are as follows: confirm a rectal perforation above the peritoneal reflection, perform peritoneoscopy using a standard gastroscope, grasp the small bowel with retrieval forceps and pull it through the rectal hole, suture the ileum and the rectum together using a TEM device, open the ileal loop, and perform endoscopic exploration. Satisfactory anastomosis and no signs of procedure-related complications were confirmed by a post procedure laparotomy. CONCLUSIONS: Ileorectal bypass through a transanal access is technically feasible in a porcine model, and although still at an experimental stage, it could become a surgical option for treating some types of colonic strictures.

RESUMEN

OBJECTIVE: Nodal status is one of the most important long-term prognostic factors for esophageal cancer. The aim of this study was to evaluate the ability of near-infrared (NIR) light fluorescent imaging to identify the lymphatic drainage pattern of esophageal cancer. METHODS: Patients with distal esophageal cancer or esophagogastric junction cancer scheduled for esophagectomy were enrolled in this study. Before surgery, an endoscopy was performed with submucosal injection of 2 cc of indocyanine green (ICG) around the tumor. Real-time NIR images from the surgical field were obtained for each patient to visualize the lymphatic ICG drainage. RESULTS: A total of nine patients were included in this study. Ivor Lewis esophagectomy was performed in all cases. ICG drainage was visualized to first drain along the left gastric nodes in eight patients (88.9%) and toward the diaphragmatic nodes in one patient (11.1%). The median number of resected nodes was 32. Three patients (33.3%) presented nodal involvement. All of them had positive nodes in the first nodal station identified with ICG. CONCLUSIONS: Evaluation of the lymphatic drainage pattern with real-time NIR light fluorescent technique is feasible. Distal and esophagogastric junction tumors showed to drain first in the left gastric nodes in most of the cases.

RESUMEN

We describe the case of a patient successfully reconstructed with laparoscopic retrosternal gastric pull-up after esophagectomy for unresectable posterior mediastinal inflammatory myofibroblastic tumor, eroding into the esophagus and compressing the airways. A partial esophagectomy with esophagostomy was performed for treatment of esophageal pleural fistula and empyema, while the airways were managed with the placement of an endobronchial stent. Gastrointestinal reconstruction was performed using a laparoscopic approach to create a retrosternal tunnel for gastric conduit pull-up and cervical anastomosis. The patient was discharged uneventfully after 6 d, and has done very well at home with normal diet.

RESUMEN

BACKGROUND: Surgery for benign esophageal disease is mostly performed either by general surgeons (GS) or cardiothoracic surgeons (CTS) in the United States. The purpose of this study was to evaluate the effect of surgeon specialty on perioperative outcomes of surgery for benign esophageal diseases. MATERIALS AND METHODS: We have conducted a retrospective analysis using the ACS-NSQIP during the period of 2006-2013. Patients who underwent paraesophageal hernia (PEH) repair, gastric fundoplication, or Heller esophagomyotomy were divided into two groups according to the specialty of the surgeon (GS or CTS). Outcomes compared between the two groups using multivariable logistic regression included 30-day mortality, overall morbidity, discharge destination, hospital length of stay (LOS), and readmission rates. RESULTS: Most of the surgeries were performed by general surgeons (PEH: 97.1%; fundoplication: 97.6%; Heller: 91.6%). Patients had lower comorbidities, better physical condition, and underwent a laparoscopic approach more frequently in the GS group. Regression analysis showed that GS group had a lower mortality rate (operating room, 0.44; 95% confidence interval [CI]: 0.23-0.86; P = .017), shorter LOS, and more home discharge for patients undergoing PEH repair. Mortality, morbidity, readmission, LOS, and home discharge were comparable between GS and CTS in fundoplication and Heller esophagomyotomy. CONCLUSION: GS perform most of esophageal surgeries for benign diseases. GS group has better outcomes in PEH repair compared with CTS, whereas there is no difference in the overall outcomes between GS and CTS in fundoplication and Heller esophagomyotomy. These results show that specialization is not always the answer to better outcomes. Difference in outcomes, however, might be related to disease severity, approach needed, or case volume.

RESUMEN

BACKGROUND: Despite the increased risk for nodal disease, definitive endoscopic resection is being increasingly offered for lesions invasive into the submucosa based on the success with intramucosal tumors. The aim of this study was to evaluate survival after esophagectomy alone for confirmed submucosal tumors after endoscopic resection. METHODS: Patients from seven centers in the USA who underwent esophagectomy for submucosal tumors removed with endoscopic resection were analyzed. Nodal involvement was correlated with recurrence and survival. RESULTS: We identified 23 patients with submucosal esophageal adenocarcinoma. Esophagectomy was performed at a median of 2 months (Interquartile range 1-3) after the endoscopic resection. There was no postoperative mortality. Positive nodal disease was seen in 26 % of patients on final pathology. At a median of 37 months (Interquartile range 25-55), 91 % of patients were alive and free of disease. The disease-specific 5-year survival was 88 %. Disease-specific 5-year survival was 67 % in patients with positive nodal metastases and 100 % in those without (p = 0.159). CONCLUSIONS: Esophagectomy is curative in the majority of patients with submucosal tumors even in the presence of nodal metastases. These data serve as a benchmark for comparison when considering extending the indications for therapeutic endoscopic resection for submucosal tumors in the future.

RESUMEN

Rhabdomyomatous well-differentiated esophageal liposarcomas are extremely rare. As of August 2016, only one other such case has been reported in the English-language medical literature. Liposarcomas in general are one of the most common soft tissue neoplasms in adults, but the incidence of primary esophageal liposarcomas is exceptionally low. There have been only 42 reported cases of primary liposarcoma of the esophagus worldwide thus far. These malignancies are harbored within giant fibrovascular polyps, which slowly grow within the esophageal lumen causing obstructing symptoms. We hereby present the case of a 68-year-old male patient who came in with a 2-mo history of worsening intermittent dysphagia, persistent cough, and postprandial retrosternal pain. After an esophagogastroduodenoscopy, a computed tomographic scan, and a diagnostic endoscopy, complete endoscopic resection was performed of the 13 cm × 6 cm × 2.6 cm fibrovascular polyp. A literature review was done and results are presented herein.

RESUMEN

AIM: To identify rates of post-discharge complications (PDC), associated risk factors, and their influence on early hospital outcomes after esophagectomy. METHODS: We used the 2005-2013 American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database to identify patients ≥ 18 years of age who underwent an esophagectomy. These procedures were categorized into four operative approaches: transhiatal, Ivor-Lewis, 3-holes, and non-gastric conduit. We selected patient data based on clinical relevance to patients undergoing esophagectomy and compared demographic and clinical characteristics. The primary outcome was PDC, and secondary outcomes were hospital readmission and reoperation. The patients were then divided in 3 groups: no complication (Group 1), only pre-discharge complication (Group 2), and PDC patients (Group 3). A modified Poisson regression analysis was used to identify risk factors associated with developing post-discharge complication, and risk ratios were estimated. RESULTS: 4483 total patients were identified, with 8.9% developing PDC within 30-d after esophagectomy. Patients who experienced complications post-discharge had a median initial hospital length of stay (LOS) of 9 d; however, PDC occurred on average 14 d following surgery. Patients with PDC had greater rates of wound infection (41.0% vs 19.3%, P < 0.001), venous thromboembolism (16.3% vs 8.9%, P < 0.001), and organ space surgical site infection (17.1% vs 11.0%, P = 0.001) than patients with pre-discharge complication. The readmission rate in our entire population was 12.8%. PDC patients were overwhelmingly more likely to have a reoperation (39.5% vs 22.4%, P < 0.001) and readmission (66.9% vs 6.6%, P < 0.001). BMI 25-29.9 and BMI ≥ 30 were associated with increased risk of PDC compared to normal BMI (18.5-25). CONCLUSION: PDC after esophagectomy account for significant number of reoperations and readmissions. Efforts should be directed towards optimizing patient's health pre-discharge, with possible prevention programs at discharge.
