Retrosternal herniation of transverse colon following minimal invasive esophagectomy causing dysphagia: A case report

INTRODUCTION AND IMPORTANCE

Minimally invasive esophagectomy has emerged as the established standard for treating esophageal cancer. The gastric graft is usually placed in the posterior mediastinum or the retrosternal tunnel for reconstruction. Hiatal hernia occurrence is more common in the posterior mediastinal reconstruction and is more frequently observed in laparoscopic compared to open approach. On the other hand, retrosternal hernia is a rare complication that deserves greater attention, considering the increasing popularity of retrosternal reconstruction in esophageal cancer treatment.

CASE PRESENTATION

We present the case of a 55-year-old male patient who underwent minimally invasive esophagectomy with retrosternal reconstruction using gastric conduit and cervical anastomosis. After four years, the patient experienced symptoms, including dyspnea and chest pain. CT scan revealed transverse colon herniation into the retrosternal tunnel.

CLINICAL DISCUSSION

Our diagnosis was retrosternal herniation of the transverse colon. Although there was no sign of obstruction, the abundant colon in the retrosternal space caused mass effect symptoms. For that reason, we performed laparoscopic surgery to release the herniated organ and close the hernia hole. Postoperatively, the patient had a satisfactory recovery, and a follow-up CT scan confirmed the absence of any remaining herniated organs.

CONCLUSION

While hiatal hernia is a well-known complication in minimally invasive esophagectomy, retrosternal hernia is a lesser-known entity. Surgical intervention is necessary to alleviate symptoms caused by herniation or address complications such as strangulation. The occurrence of retrosternal hernia warrants further attention and research in the future.

Management of Major Complications After Esophagectomy

Esophagectomy remains a procedure with one of the highest complication rates. Given the advances in medical and surgical management of patients and increased patient survival, the number of complications reported has increased. There are different grading systems for complications which vary based on severity or organ system, with the Esophageal Complications Consensus Group unifying them. Management involves conservative intervention and dietary modification to endoscopic interventions and surgical reintervention. Treatment is etiology specific but rehabilitation and patient optimization play a significant role in managing these complications by preventing them. Management is a step-up approach depending on the severity of symptoms.

Paraconduit hernia following esophagectomy: Is it safe to watch and wait?

OBJECTIVES

We hypothesized that emergency complications related to asymptomatic paraconduit hernias may occur less often than generally believed. Therefore, we assessed the occurrence and timing of paraconduit hernia diagnosis after esophagectomy, as well as outcomes of these asymptomatic patients managed with a watch-and-wait approach.

METHODS

From 2006 to 2021, 1214 patients underwent esophagectomy with reconstruction at the Cleveland Clinic. Among these patients, computed tomography scans were reviewed to identify paraconduit hernias. Medical records were reviewed for timing of hernia diagnosis, hernia characteristics, and patient symptoms, complications, and management. During this period, patients with asymptomatic paraconduit hernias were typically managed nonoperatively.

RESULTS

Paraconduit hernias were identified in 37 patients. Of these, 31 (84%) had a pre-esophagectomy hiatal hernia. Twenty-one hernias (57%) contained colon, 7 hernias (19%) contained pancreas, and 9 hernias (24%) contained multiple organs. Estimated prevalence of paraconduit hernia was 3.3% at 3 years and 7.7% at 10 years. Seven patients (19%) had symptoms, 4 of whom were repaired electively, with 2 currently awaiting repairs. No patient with a paraconduit hernia experienced an acute complication that required emergency intervention.

CONCLUSIONS

The risk of paraconduit hernia increases with time, suggesting that long-term symptom surveillance is reasonable. Emergency complications as a result of asymptomatic paraconduit hernias are rare. A small number of patients will experience hernia-related symptoms, sometimes years after hernia diagnosis. Our findings suggest that observation of asymptomatic paraconduit hernias (watch and wait) may be considered, with repair considered electively in patients with persistent symptoms.

Internal Hernia Through a Mesenteric Defect Following Esophagectomy and Reconstruction With a Stomach-Preserved Ileocolic Interposition

Esophagectomy is the standard treatment for esophageal cancer and often involves the stomach as a substitute organ for esophageal reconstruction. However, we actively perform stomach-preserved ileocolic interposition because of its advantages in gastrointestinal function and the prevention of reflux esophagitis. Despite its benefits, few facilities perform esophageal reconstruction with ileocolic interposition; hence, postoperative complications following this procedure have rarely been reported. We present the first case of internal hernia through a mesenteric defect following esophagectomy and reconstruction with a stomach-preserved ileocolic interposition. This type of internal hernia after esophageal cancer surgery is a rare complication following a common gastric pull-up reconstruction. A 66-year-old Japanese female underwent esophagectomy and reconstruction with stomach-preserved ileocolic interposition for stage I esophageal cancer. One month after surgery, the patient experienced abdominal pain and vomiting. CT showed a dilated small bowel and a suspected postoperative adhesive bowel obstruction. Despite conservative management, the patient experienced recurrent episodes that required hospitalization. Although an exact preoperative diagnosis was not made, we decided on a surgical exploration six months after the first symptoms appeared. Laparotomy revealed an internal herniation through a mesenteric defect between the transverse mesocolon and the ileum mesentery following ileocolic interposition. We then repositioned the fitted small intestine and closed the mesenteric defects. The patient recovered uneventfully without a hernia recurrence. Minimally invasive techniques for treating esophageal cancer are becoming more common. As survival rates improve, the number of internal hernia cases, such as those described in this report, will likely increase. Therefore, more cases are needed to determine whether closing mesenteric defects can effectively prevent herniation. However, immediate surgical treatment should be considered based on the symptoms, even when a preoperative diagnosis is difficult.

Postesophagectomy Diaphragmatic Prolapse after Robot-Assisted Minimally Invasive Esophagectomy (RAMIE)

BACKGROUND

Postesophagectomy diaphragmatic prolapse (PDP) is a major complication after esophagectomy with significant mortality and morbidity. However, in the current literature, treatment and outcomes are not evaluated for patients undergoing an Ivor Lewis Robot-assisted minimally invasive esophagectomy (IL-RAMIE). The aim of this study is to evaluate the incidence of PDP after IL-RAMIE. Moreover, the study aims to determine whether using a minimally invasive approach in the management of PDP after an IL-RAMIE procedure is safe and feasible.

MATERIALS AND METHODS

This study includes all patients who received an IL-RAMIE at our high-volume center (>200 esophagectomies/year) between April 2017 and December 2022 and developed PDP. The analysis focuses on time to prolapse, symptoms, treatment, surgical method, and recurrence rates of these patients.

RESULTS

A total of 185 patients underwent an IL-RAMIE at our hospital. Eleven patients (5.9%) developed PDP. Patients presented with PDP after a medium time of 241 days with symptoms like reflux, nausea, vomiting, and pain. One-third of these patients did not suffer from any symptoms. In all cases, a CT scan was performed in which the colon transversum always presented as the herniated organ. In one patient, prolapse of the small intestine, pancreas, and greater omentum also occurred. A total of 91% of these patients received a revisional surgery in a minimally invasive manner with a mean hospital stay of 12 days. In four patients, PDP recurred (36%) after 13, 114, 119 and 237 days, respectively.

CONCLUSION

This study shows that a minimally invasive approach in repositioning PDP is a safe and effective option after IL-RAMIE.

Postoperative Hiatal Hernia after Ivor Lewis Esophagectomy-A Growing Problem in the Age of Minimally Invasive Surgery

BACKGROUND

Even though minimally invasive esophagectomy is a safe and oncologically effective procedure, several authors have reported an increased risk of postoperative hiatal hernia (PHH). This study evaluates the incidence and risk factors of PHH after hybrid minimally invasive (HMIE) versus open esophagectomy (OE).

METHODS

A retrospective single-center analysis was performed on patients who underwent Ivor Lewis esophagectomy between January 2009 and April 2018. Computed tomography scans and patient files were reviewed to identify the PHH.

RESULTS

306 patients were included (152 HMIE; 154 OE). Of these, 23 patients (8%) developed PHH. Most patients (13/23, 57%) were asymptomatic at the time of diagnosis and only 4 patients (17%) presented in an emergency setting with incarceration. The rate of PHH was significantly higher after HMIE compared to OE (13.8% vs. 1.3%, p < 0.001). No other risk factors for the development of PHH were identified in uni- or multi-variate analysis. Surgical repair of PHH was performed in 19/23 patients (83%). The recurrence rate of PHH after surgical repair was 32% (6/19 patients).

CONCLUSIONS

The development of PHH is a relevant complication after hybrid minimally invasive esophagectomy. Although most patients are asymptomatic, surgical repair is recommended to avoid incarceration with potentially fatal outcomes. Innovative techniques for the prevention and repair of PHH are urgently needed.

Efficacy and Postoperative Outcomes of Laparoscopic Retrosternal Route Creation for the Gastric Conduit: Propensity Score-Matched Comparison to Posterior Mediastinal Reconstruction

BACKGROUND

Retrosternal reconstruction has lower risks for severe postoperative morbidities, such as gastro-tracheal fistula or esophageal hiatal hernia. We have previously reported the laparoscopic retrosternal route creation (LRRC) method, but its safety and efficacy remain unclear.

METHODS

In total, 374 patients with esophageal carcinoma who underwent minimally invasive McKeown esophagectomy in the prone position between 2010 and 2021 were retrospectively reviewed. We performed a propensity score-matched analysis with the simple, nearest-neighbor method and no calipers to compare postoperative outcomes and reconstructed gastric conduit functionality between patients who underwent LRRC and counterparts who underwent posterior mediastinal reconstruction.

RESULTS

After matching, 62 patients were included in the laparoscopic retrosternal group (LR group) or posterior mediastinal group (PM group). No significant differences were observed between the groups, apart from the number of robot-assisted surgeries, the extent of lymph node dissection, and the method of cervical anastomosis. There were no significant differences in the incidence of Clavien-Dindo grade ≥ 2 complications. Gastro-tracheal fistula (n = 1) and esophageal hiatal hernia (n = 2) occurred in the PM group but not in the LR group. There were no differences in the incidence of pulmonary embolism between the groups (5% vs. 5%). The postoperative anastomotic stenosis rate was similar (16% vs. 27%, p = 0.192). Endoscopic findings of reflux esophagitis (modified Los Angeles classification ≥ M) at 1 year after surgery were significantly better in the LR group (p = 0.037).

CONCLUSIONS

LRRC for gastric conduit reconstruction is safe and valuable. It is associated with good reconstructed gastric conduit function.

Safety, efficacy, and cost-effectiveness of minimally invasive esophagectomies versus open esophagectomies: an umbrella review

Traditionally, esophageal oncological resections have been performed via open approaches with well-documented levels of morbidity and mortality complicating the postoperative course. In contemporary terms, minimally invasive approaches have garnered sustained support in all areas of surgery, and there has been an exponential adaptation of this technology in upper GI surgery with the advent of laparoscopic and robotic techniques. The current literature, while growing, is inconsistent in reporting on the benefits of minimally invasive esophagectomies (MIEs) and this makes it difficult to ascertain best practice. The objective of this review was to critically appraise the current evidence addressing the safety, efficacy, and cost-effectiveness of MIEs versus open esophagectomies. A systematic review of the literature was performed by searching nine electronic databases to identify any systematic reviews published on this topic and recommended Joanna Briggs Institute approach to critical appraisal, study selection, data extraction and data synthesis was used to report the findings. A total of 13 systematic reviews of moderate to good quality encompassing 143 primary trials and 36,763 patients were included in the final synthesis. Eleven reviews examined safety parameters and found a generalized benefit of MIE. Efficacy was evaluated by eight systematic reviews and found each method to be equivalent. There were limited data to judiciously appraise cost-effectiveness as this was only evaluated in one review involving a single trial. There is improved safety and equivalent efficacy associated with MIE when compared with open esophagectomy. Cost-effectiveness of MIE cannot be sufficiently supported at this point in time. Further studies, especially those focused on cost-effectiveness are needed to strengthen the existing evidence to inform policy makers on feasibility of increased assimilation of this technology into clinical practice.

An incisional hernia containing a gangrenous gallbladder: a case report and review of the literature

We present a 76-year-old male who presented to the emergency department with 24 hours of sudden onset, severe abdominal pain. Physical exam and laboratory analysis indicated acute cholecystitis, and a CT scan demonstrated a ventral hernia containing an inflamed gallbladder. This patient was managed operatively with an open cholecystectomy. The ventral hernia was not repaired at the index operation in the setting of frank gallbladder necrosis. The patient recovered well after a short post-operative stay. This report is intended to illustrate an unusual presentation of acute, gangrenous cholecystitis with herniation through the ventral abdominal wall.

Network meta-analysis of randomized controlled trials on esophagectomies in esophageal cancer: The superiority of minimally invasive surgery

BACKGROUND

Previous meta-analyses, with many limitations, have described the beneficial nature of minimal invasive procedures.

AIM

To compare all modalities of esophagectomies to each other from the results of randomized controlled trials (RCTs) in a network meta-analysis (NMA).

METHODS

We conducted a systematic search of the MEDLINE, EMBASE, Reference Citation Analysis (https://www.referencecitationanalysis.com/) and CENTRAL databases to identify RCTs according to the following population, intervention, control, outcome (commonly known as PICO): P: Patients with resectable esophageal cancer; I/C: Transthoracic, transhiatal, minimally invasive (thoracolaparoscopic), hybrid, and robot-assisted esophagectomy; O: Survival, total adverse events, adverse events in subgroups, length of hospital stay, and blood loss. We used the Bayesian approach and the random effects model. We presented the geometry of the network, results with probabilistic statements, estimated intervention effects and their 95% confidence interval (CI), and the surface under the cumulative ranking curve to rank the interventions.

RESULTS

We included 11 studies in our analysis. We found a significant difference in postoperative pulmonary infection, which favored the minimally invasive intervention compared to transthoracic surgery (risk ratio 0.49; 95%CI: 0.23 to 0.99). The operation time was significantly shorter for the transhiatal approach compared to transthoracic surgery (mean difference -85 min; 95%CI: -150 to -29), hybrid intervention (mean difference -98 min; 95%CI: -190 to -9.4), minimally invasive technique (mean difference -130 min; 95%CI: -210 to -50), and robot-assisted esophagectomy (mean difference -150 min; 95%CI: -240 to -53). Other comparisons did not yield significant differences.

CONCLUSION

Based on our results, the implication of minimally invasive esophagectomy should be favored.

Increased risk of diaphragmatic herniation following esophagectomy with a minimally invasive abdominal approach

OBJECTIVE

Diaphragmatic herniation is a rare complication following esophagectomy, associated with risks of aspiration pneumonia, bowel obstruction, and strangulation. Repair can be challenging due to the presence of the gastric conduit. We performed this systematic review and meta-analysis to determine the incidence and risk factors associated with diaphragmatic herniation following esophagectomy, the timing and mode of presentation, and outcomes of repair.

METHODS

A systematic search using Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines was performed using four major databases. A meta-analysis of diaphragmatic herniation incidence following esophagectomies with a minimally invasive abdominal (MIA) approach compared with open esophagectomies was conducted. Qualitative analysis was performed for tumor location, associated symptoms, time to presentation, and outcomes of postdiaphragmatic herniation repair.

RESULTS

This systematic review consisted of 17,052 patients from 32 studies. The risk of diaphragmatic herniation was 2.74 times higher in MIA esophagectomy compared with open esophagectomy, with pooled incidence of 6.0% versus 3.2%, respectively. Diaphragmatic herniation was more commonly seen following surgery for distal esophageal tumors. Majority of patients (64%) were symptomatic at diagnosis. Presentation within 30 days of operation occurred in 21% of cases and is twice as likely to require emergent repair with increased surgical morbidity. Early diaphragmatic herniation recurrence and cardiorespiratory complications are common sequelae following hernia repair.

CONCLUSIONS

In the era of MIA esophagectomy, one has to be cognizant of the increased risk of diaphragmatic herniation and its sequelae. Failure to recognize early diaphragmatic herniation can result in catastrophic consequences. Increased vigilance and decreased threshold for imaging during this period is warranted.

Robotic repair of post-oesophagectomy hiatal hernia

Diaphragmatic hiatal hernia is a potential complication of oesophagectomy in cancer patients. Over the past decades, laparoscopy has become the preferred approach to repairing this condition due to the reduced morbidity, faster recovery and shorter hospital stay when compared with traditional open surgery. The development of robotic technology has added to the benefits of minimally invasive approaches, offering potential technical advantages and overcoming some limitations of traditional laparoscopic techniques when performing complex procedures. We present the first report of a robotic post-oesophagectomy hiatal hernia repair.

Abdominal Viscera Migration Performing Hemodynamic Instability after Esophagectomy: A Case Report

Hiatal hernia is a rare postoperative complication of esophagectomy in the treatment of esophageal cancer. Although rare, its incidence increased after the establishment of minimally invasive surgical techniques. The patient is usually oligosymptomatic, and the diagnosis is made in the late postoperative period, during outpatient follow-up. The initial presentation of hiatus hernia with hemodynamic instability is a rare condition that has never been described in the literature before. In the following report, we address the clinical picture, diagnosis, and treatment for this condition, discussing the main nuances of the literature.

Ligamentum teres augmentation (LTA) for hiatal hernia repair after minimally invasive esophageal resection: a new use for an old structure

Purpose

Hiatal hernias with intrathoracic migration of the intestines are serious complications after minimally invasive esophageal resection with gastric sleeve conduit. High recurrence rates have been reported for standard suture hiatoplasties. Additional mesh reinforcement is not generally recommended due to the serious risk of endangering the gastric sleeve. We propose a safe, simple, and effective method to close the hiatal defect with the ligamentum teres.

Methods

After laparoscopic repositioning the migrated intestines, the ligamentum teres is dissected from the ligamentum falciforme and the anterior abdominal wall. It is then positioned behind the left lobe of the liver and swung toward the hiatal orifice. Across the anterior aspect of the hiatal defect it is semi-circularly fixated with non-absorbable sutures. Care should be taken not to endanger the blood supply of the gastric sleeve.

Results

We have used this technique for a total of 6 patients with hiatal hernias after hybrid minimally invasive esophageal resection in the elective (n = 4) and emergency setting (n = 2). No intraoperative or postoperative complications have been observed. No recurrence has been reported for 3 patients after 3 months.

Conclusion

Primary suture hiatoplasties for hiatal hernias after minimally invasive esophageal resection can be technically challenging, and high postoperative recurrence rates are reported. An alternative, safe method is needed to close the hiatal defect. Our promising preliminary experience should stimulate further studies regarding the durability and efficacy of using the ligamentum teres hepatis to cover the hiatal defect.

Laparoscopic creation of a retrosternal route for gastric conduit reconstruction

BACKGROUND

Retrosternal reconstruction is associated with a lower risk of mediastinitis, gastro-tracheal fistula, and hiatal hernia. Historically, traumatic manual creation of the retrosternal tunnel has been performed using one's fist. We report a novel and atraumatic laparoscopic procedure to create the retrosternal route.

METHODS

We have laparoscopically created the retrosternal route in 25 thoracoscopic, mediastinoscopic, or robot-assisted minimally invasive esophagectomies since August 2019. Specifically, a peritoneal incision is started at the dorsal side of the xiphoid process. Through a 12-mm port inserted slightly to the right of and superior to the umbilical camera port, we dissect loose connective tissues from the caudal to the cranial side using behind the sternum and inside the internal thoracic vessels as landmarks. The time required to create the route was calculated. Then, the cumulative sum (CUSUM) method and the simple moving average of five cases were used to evaluate the learning curve of this novel procedure. Operative outcomes were analyzed according to the learning curve results and also compared with 25 cases of postmediastinal reconstruction counterparts.

RESULTS

Twenty-five patients were divided into the early group (six patients) and late group (19 patients) based on the peak of the CUSUM chart. The time required for route creation was 28.5 min (median) in the early and 15 min in the late group, indicating a significant difference (P = 0.038). The overall incidence of pleural injury was 20% (5 of 25 patients), with no significant difference between the groups. There was no significant difference in the incidence of perioperative complications. Also, there were no significant differences in perioperative complications or gastric conduit functions 1 year after surgery between the retrosternal and the postmediastinal reconstruction.

CONCLUSION

Laparoscopic creation of a retrosternal route for gastric conduit reconstruction is safe and feasible and has a short learning curve.

Paraconduit Hiatal Hernia Following Esophagectomy: Incidence, Risk Factors, Outcomes and Repair

BACKGROUND

Paraconduit hiatal hernia (PCHH) is a known complication of esophagectomy with significant morbidity. PCHH may be more common with the transition to a minimally invasive approach and improved survival. We studied the PCHH occurrence following minimally invasive esophagectomy to determine the incidence, treatment, and associated risk factors.

METHODS

We retrospectively reviewed records of patients who underwent esophagectomy at an academic tertiary care center between 2013-2020. We divided the cohort into those who did and did not develop PCHH, identifying differences in demographics, perioperative characteristics and outcomes. We present video of our laparoscopic repair with mesh.

RESULTS

Of 49 patients who underwent esophagectomy, seven (14%) developed PCHH at a median of 186 d (60-350 d) postoperatively. They were younger (57 versus 64 y, P< 0.01), and in cases of resection for cancer, more likely to develop tumor recurrence (71% versus 23%, P= 0.02). There was a significant difference in 2-y cancer free survival of patients with a PCHH (PCHH 19% versus no hernia 73%, P< 0.01), but no significant difference in 5-y overall survival (PCHH 36% versus no hernia 68%, P= 0.18). Five of seven PCHH were symptomatic and addressed surgically. Four PCHH repairs recurred at a median of 409 d.

CONCLUSIONS

PCHH is associated with younger age and tumor recurrence, but not mortality. Safe repair of PCHH can be performed laparoscopically with or without mesh. Further studies, including systematic video review, are needed to address modifiable risk factors and identify optimal techniques for durable repair of post-esophagectomy PCHH.

Incidence and Risk Factors for Diaphragmatic Herniation following Esophagectomy for Cancer

OBJECTIVE

To evaluate the incidence and risk factors of diaphragmatic herniation following esophagectomy for cancer (DHEC), and assess the results of surgical repair.

SUMMARY BACKGROUND DATA

The current incidence of DHEC is discussed with conflicting data regarding its treatment and natural course.

METHODS

Monocentric retrospective cohort study(2009-2018). From 902 patients, 719 patients with a complete follow-up of CT-scans after transthoracic esophagectomy for cancer were reexamined to identify the occurrence of a DHEC. The incidence of DHEC was estimated using Kalbfleisch and Prentice method and risk factors of DHEC were studied using the Fine and Gray competitive risk regression model by treating death as a competing event. Survival was analyzed.

RESULTS

5-year DHEC incidence was 10.3% [95%CI, 7.8%-13.2%](n = 59), asymptomatic in 54.2% of cases. In the multivariable analysis, the risk factors for DHEC were: presence of hiatal hernia on preoperative CT scan (HR = 1.72[1.01-2.94], p = 0.046), previous hiatus surgery (HR = 3.68[1.61-8.45], p = 0.002), gastroesophageal junction tumor location (HR = 3.51[1.91-6.45], p < 0.001), neoadjuvant chemoradiotherapy (HR = 4.27[1.70-10.76], p < 0.001), and minimally invasive abdominal phase (HR = 2.98[1.60-5.55], p < 0.001). A cure for DHEC was achieved in 55.9%. The postoperative mortality rate was nil, the overall morbidity rate was 12.1%, and the DHEC recurrence rate was 30.3%. Occurrence of DHEC was significantly associated with a lower hazard rate of death in a time-varying Cox's regression analysis (HR = 0.43[0.23-0.81], p = 0.010).

CONCLUSIONS

The 5-year incidence of DHEC is 10.3% and is associated with a favorable prognosis. Surgical repair of symptomatic or progressive DHEC is associated with an acceptable morbidity. However, the optimal surgical repair technique remains to be determined in view of the large number of recurrences.

Diaphragmatic herniation after esophagogastric surgery: systematic review and meta-analysis

Introduction

The anatomy of the esophageal hiatus is altered during esophagogastric surgery with an increased risk of postoperative hiatus hernia (HH). The purpose of this article was to examine the current evidence on the surgical management and outcomes associated with HH after esophagogastric surgery for cancer.

Materials and methods

Systematic review and meta-analysis. Web of Science, PubMed, and EMBASE data sets were consulted.

Results

Twenty-seven studies were included for a total of 404 patients requiring surgical treatment for HH after esophagogastric surgery. The age of the patients ranged from 35 to 85 years, and the majority were males (82.3%). Abdominal pain, nausea/vomiting, and dyspnea were the commonly reported symptoms. An emergency repair was required in 51.5%, while a minimally invasive repair was performed in 48.5%. Simple suture cruroplasty and mesh reinforced repair were performed in 65% and 35% of patients, respectively. The duration between the index procedure and HH repair ranged from 3 to 144 months, with the majority (67%) occurring within 24 months. The estimated pooled prevalence rates of pulmonary complications, anastomotic leak, overall morbidity, and mortality were 14.1% (95% CI = 8.0–22.0%), 1.4% (95% CI = 0.8–2.2%), 35% (95% CI = 20.0–54.0%), and 5.0% (95% CI = 3.0–8.0%), respectively. The postoperative follow-up ranged from 1 to 110 months (mean = 24) and the pooled prevalence of HH recurrence was 16% (95% CI = 13.0–21.6%).

Conclusions

Current evidence reporting data for HH after esophagogastric surgery is narrow. The overall postoperative pulmonary complications, overall morbidity, and mortality are 14%, 35%, and 5%, respectively. Additional studies are required to define indications and treatment algorithm and evaluate the best technique for crural repair at the index operation in an attempt to minimize the risk of HH.

Falciform Ligament Flap as Crural Buttress in Laparoscopic Hiatal Hernia Repair

Background: Crural repair is an essential technical component in laparoscopic hiatal hernia surgery, but there is no consensus regarding the optimal method to prevent postoperative hernia recurrence. Mesh augmentation, especially with permanent materials, is associated with dysphagia and complications. The rotational falciform ligament flap (FLF) has been reported to be effective in reinforcing standard suture closure of the hiatus. Materials and Methods: Patients with primary or secondary hiatal hernia in whom FLF was used to buttress the hiatus repair were included. The FLF was dissected from the anterior abdominal wall, detached from the umbilical area, and transposed below the left lateral liver segment to buttress the cruroplasty. Indocyanine green fluorescence was used to assess vascularization of the flap before and after mobilization. Results: Eighteen consecutive patients underwent laparoscopic FLF cruroplasty reinforcement between October 2019 and January 2021. Indications were primary hiatal hernia (n = 9), recurrent hiatal hernia (n = 4), postsleeve gastrectomy hernia (n = 1), prophylactic hiatal repair during esophagectomy and gastric conduit reconstruction (n = 2), and postesophagectomy hernia (n = 2). All flaps were well vascularized and covered the entire hiatal area. There was no morbidity. At a median follow-up of 8 months (range 3-15), the symptomatic and quality of life scores significantly improved compared with baseline (P < .001), and no anatomic hernia recurrences were detected. Conclusions: FLF is safe for crural buttress and is a viable alternative to mesh in laparoscopic hiatal hernia surgery.

Robotics and minimally invasive esophageal surgery

The robotic platform has permeated esophageal surgery both in the abdominal and thoracic approaches. The most widely studied entities include achalasia, gastroesophageal reflux disease, hiatal hernia and esophageal cancer. A literature review of robotic surgeries for the management of the above mentioned disorders is presented. Data is limited to meta-analyses, case series, or small prospective trials in the different indications. One exception is a randomized controlled trial looking at outcomes in esophageal cancer being managed with a hybrid robotic versus open approach. Overall differences when comparing laparoscopic or thoracoscopic surgery to robotic are few. These differences are best highlighted in the achalasia and esophageal cancer literature. There are less intraoperative mucosal injuries in robotic Heller myotomy. A large meta analysis found a rate of 1% versus 24.5% mucosal injury rate favoring the robotic versus laparoscopic Heller myotomy methods. With respect to esophagectomy data, there is slightly less vocal cord paralysis in the robotic versus MIE data, with a P value of 0.044. However, length of stay, intraoperative bleeding and major morbidity are similar across the various indications. Robotic esophageal surgery is a safe alternative to laparoscopic/thoracoscopic techniques. Further large-scale randomized trials are needed to fully ascertain if it yields superior outcomes.

A long-term follow-up study of minimally invasive Ivor Lewis esophagectomy with linear stapled anastomosis

BACKGROUND

Minimally invasive esophagectomy (MIE) is increasingly performed to expect lower complication rate compared to open esophagectomy. Studies of minimally invasive Ivor Lewis esophagectomy (MIILE) with circular staplers have reported better outcomes compared to MIE with cervical anastomosis, but frequent anastomotic complications have also been reported. MIILE with linear staplers is a promising alternative, but the long-term functional and oncological outcomes are uncertain.

METHODS

To evaluate the functional and oncological outcomes of MIILE with linear stapled anastomosis, a retrospective cohort study was performed in 104 patients who underwent MIILE with linear stapled anastomosis for esophageal malignant tumors. The primary endpoints were the overall complication and anastomotic leak rates. The secondary endpoints were late complications, overall and disease-free survival, and nutritional status at 6 and 12 months after MIILE.

RESULTS

Anastomotic leak occurred in 4 patients (3.8%). The short-term complication rate of grade IIIb or higher was 6.7%. During a median 57-month follow-up period, anastomotic stricture occurred in one patient, 7 required hiatal hernia repair, and 2 underwent conduit revision surgery. The 5-year overall survival and disease-free survival rates were 69.3% and 59.5%, respectively. Status of reflux esophagitis at the time of most recent evaluation was grade N/A/B/C/D in 52/10/10/13/8 among 93 patients who had follow-up endoscopy. The mean body weight loss at 6 and 12 months after MIILE was 11.3 and 11.8% with maintenance of the serum albumin level.

CONCLUSIONS

MIILE with linear stapled anastomosis is a safe procedure with a low anastomotic complication rate and favorable long-term functional and survival outcomes.

Trans-hiatal herniation following esophagectomy or gastrectomy: retrospective single-center experiences with a potential surgical emergency

PURPOSE

Trans-hiatal herniation after esophago-gastric surgery is a potentially severe complication due to the risk of bowel incarceration and cardiac or respiratory complaints. However, measures for prevention and treatment options are based on a single surgeon´s experiences and small case series in the literature.

METHODS

Retrospective single-center analysis on patients who underwent surgical repair of trans-hiatal hernia following gastrectomy or esophagectomy from 01/2003 to 07/2020 regarding clinical symptoms, hernia characteristics, pre-operative imaging, hernia repair technique and perioperative outcome.

RESULTS

Trans-hiatal hernia repair was performed in 9 patients following abdomino-thoracic esophagectomy (40.9%), in 8 patients following trans-hiatal esophagectomy (36.4%) and in 5 patients following conventional gastrectomy (22.7%). Gastrointestinal symptoms with bowel obstruction and pain were mostly prevalent (63.6 and 59.1%, respectively), two patients were asymptomatic. Transverse colon (54.5%) and small intestine (77.3%) most frequently prolapsed into the left chest after esophagectomy (88.2%) and into the dorsal mediastinum after gastrectomy (60.0%). Half of the patients had signs of incarceration in pre-operative imaging, 10 patients underwent emergency surgery. However, bowel resection was only necessary in one patient. Hernia repair was performed by suture cruroplasty without (n = 12) or with mesh reinforcement (n = 5) or tension-free mesh interposition (n = 5). Postoperative pleural complications were most frequently observed, especially in patients who underwent any kind of mesh repair. Three patients developed recurrency, of whom two underwent again surgical repair.

CONCLUSION

Trans-hiatal herniation after esophago-gastric surgery is rare but relevant. The role of surgical repair in asymptomatic patients is disputed. However, early hernia repair prevents patients from severe complications. Measures for prevention and adequate closure techniques are not yet defined.

Hiatal Hernia with Acute Obstructive Symptoms After Minimally Invasive Oesophagectomy

BACKGROUND

To evaluate the incidence, treatment and postoperative outcomes of an acute hiatal hernia (HH) after totally minimally invasive esophagectomy (tMIE) for oesophageal cancer.

METHODS

The incidence and treatment of acute HH were analysed from our prospective database including all patients that were surgically treated for oesophageal cancer in the period between January 2011 and December 2018.

RESULTS

Within the study period, the database contained 307 patients that underwent minimally invasive oesophagectomy. Patients' characteristics were in line with the literature of Western data. The incidence of acute HH was 2.6% (N = 8). All patients presented with gastro-intestinal obstruction symptoms, that required acute operation, repositioning of the intrathoracic organs in combination with a crural repair. Mesh reinforcement was used in 38% (N = 3). In two patients, the intestines were partially resected due to ischemia. Postoperative complications, as atrial fibrillation, respiratory failure and anastomotic leakage, were seen in 63% (N = 5). Recurrence-rate was 38% (N = 3).

CONCLUSIONS

This present study demonstrates that an acute HH after tMIE is a serious complication with an incidence of 2.6%. When symptomatic and acute, HH requires surgical intervention and has high postoperative morbidity and recurrence-rate. Therefore, this requires treatment in a centre specialised in oesophageal surgery.

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.

Transdiaphragmatic herniation after transthoracic esophagectomy: an underestimated problem

Diaphragmatic transposition of intestinal organs is a major complication after esophagectomy and can be associated with significant morbidity and mortality. This study aims of to analyze a large series of patients with this condition in a single high-volume center for esophageal surgery and to suggest a novel treatment algorithm. Patients who received surgery for postesophagectomy diaphragmatic herniation between October 2003 and December 2017 were included. Retrospective analysis of demographic, clinical and surgical data was performed. Outcomes of measure were initial clinical presentation, postoperative complications, in-hospital mortality and herniation recurrence. A total of 39 patients who had surgery for postesophagectomy diaphragmatic herniation were identified. Diaphragmatic herniation occurred after a median time of 259 days following esophagectomy with the highest prevalence between 1 and 12 months. A total of 84.6% of the patients had neoadjuvant radiochemotherapy prior to esophagectomy. The predominantly effected organ was the transverse colon (87.2%) prolapsing into the left hemithorax (81.6%). A total of 20 patients required emergency surgery. Surgery always consisted of reposition of the intestinal organs and closure of the hiatal orifice; a laparoscopic approach was used in 25.6%. Major complications (Dindo-Clavien ≥ IIIb) were observed in 35.9%, hospital mortality rate was 7.7%. Three patients developed recurrent diaphragmatic herniation during follow-up. Postesophagectomy diaphragmatic herniation is a functional complication of the late postoperative course and predominantly occurs in patients with locally advanced adenocarcinoma having chemoradiation before Ivor-Lewis esophagectomy. Due to a high rate of emergency surgery with life-threatening complications not a 'wait-and-see' strategy but early surgical repair may be indicated.

Hiatal hernia after oesophagectomy: a large European survey

OBJECTIVES

Hiatal hernias (HH) after oesophagectomy are rare, and their surgical management is not well standardized. Our goal was to report on the management of HH after oesophagectomy in high-volume tertiary European French-speaking centres.

METHODS

We conducted a retrospective multicentre study among 19 European French-speaking departments of upper gastrointestinal and/or thoracic surgery. All patients scheduled or operated on for the repair of an HH after oesophagectomy were collected between 2000 and 2016. Demographics, details of the initial procedure, surgical management and long-term outcome were analysed.

RESULTS

Seventy-nine of 6608 (1.2%) patients who had oesophagectomies were included in the study. The postoesophagectomy diagnostic interval of an HH after oesophagectomy was ≤90 days (n = 17; 21%), 13 were emergency cases; between 91 days and 1 year, n = 21 (27%), 13 in emergency; ≥1 year, n = 41 (52%), 17 in emergency. The time to occurrence of HH after oesophagectomy was shorter after laparoscopy (median 308 days; interquartile range 150-693) compared to that after laparotomy (median 562 days, interquartile range 138-1768; P = 0.01). The incidence of HH after oesophagectomy was 0.73% (22/3010) after open surgery and 1.4% (26/1761) after laparoscopy (P = 0.03). Among the 79 patients, 78 were operated on: 35 had laparotomies (45%), 19 had laparoscopies (24%) and 24 (31%) had transthoracic approaches. Among the 43 urgent surgeries, 35 were open (25 laparotomies and 10 transthoracic approaches) and 8 were laparoscopies (conversion rate, 25%). Nine patients required bowel resections. Morbidity occurred in 36 (46%) patients with 1 postoperative death (1.2%). During the follow-up period, recurrent HH after oesophagectomy requiring revisional surgery developed in 8 (6 days-26 months) patients.

CONCLUSIONS

Surgical management of HH after oesophagectomy could be done by laparoscopy in patients with scheduled surgery but laparotomy or thoracotomy was preferred in urgent situations. The incidence of HH after oesophagectomy is higher and its onset earlier when laparoscopy is used at the initial oesophagectomy.

Transverse colon perforation in the mediastinum after esophagectomy: a case report

Background

While anastomotic leakage, recurrent laryngeal nerve paralysis, and pneumonia are well-known complications of esophagectomy, the incidence of hiatal hernia after esophagectomy for carcinoma has been reported to only be between 0.6 and 10%. We report a very rare case of hiatal hernia with transverse colon rupture in the mediastinum after esophagectomy in a 65-year-old woman.

Case presentation

The patient underwent definitive chemoradiotherapy for clinical stage IIA esophageal squamous cell carcinoma and salvage esophagectomy with gastric tube reconstruction through a posterior mediastinum route for residual carcinoma. Three years after the initial surgery, two metastatic nodules in the lateral and posterior segments of the liver were detected on follow-up CT and were treated with oral anticancer drugs. After 6 months, the patient was readmitted for anorexia. Upon admission, computed tomography revealed an ileus caused by a hiatal hernia. Emergent operative repair was performed; an incarcerated herniation of the transverse colon was perforated in the mediastinum, and partial transverse colon resection and colostomy were performed. Intensive care was required to control septic shock after surgery, and the patient was discharged on the 53rd postoperative day.

Conclusions

Cases of hiatal hernia with digestive tract prolapsing into the mediastinum after esophagectomy with reconstruction through posterior mediastinum are rare but potentially life-threatening complications.

Laparoscopic repair of a giant hiatal hernia after minimally invasive oesophagectomy

Minimally invasive oesophagectomy has become popular, but studies showed a higher rate of postoperative hiatus hernia compared with open oesophagectomy. Our video presents the laparoscopic biosynthetic mesh repair of a symptomatic giant hiatus hernia in a 71-year-old man who had undergone minimally invasive oesophagectomy one year earlier for distal adenocarcinoma of the oesophagus. The operative time was 120 minutes. The patient started oral intake on postoperative day one and was discharged on postoperative day three. Postoperative computed tomography at six months showed no signs of recurrence. In the setting of a symptomatic hiatus hernia post-minimally invasive oesophagectomy, we suggest an initial laparoscopic approach, because of its countless advantages.

Hiatal Hernia after Esophagectomy: An Underappreciated Complication?

BACKGROUND

The natural history of hiatal herniation of small and/or large bowel post-esophagectomy (HHBPE) in the current era of improving long-term survival and evolving surgical technique is unknown. The aim of this study was to describe the rate and risk factors of HHBPE at our hospital.

METHODS

Patients undergoing esophagectomy between January 2011 and June 2017 were included if both follow-up information and axial imaging were available beyond 3 months post-esophagectomy. Patient characteristics, disease information, and treatment factors were all included in univariate analysis comparing patients with and without HHBPE, and multivariate regression was used to identify significant independent risk factors associated with HHBPE.

RESULTS

Of 310 esophagectomy patients analyzed, 258 patients were included in the study, with 79 patients (31%) showing evidence of an HHBPE and an overall median follow-up of 24 months; 44 of 79 patients (56%) had symptoms possibly referable to HHBPE and 17 of 79 patients (22%) underwent surgical repair. On univariate analysis, neoadjuvant therapy (n = 176), higher clinical stage, minimally invasive approach (n = 154), and transhiatal esophagectomy (n = 189) were significant predictors of HHBPE (p < 0.05). On multivariate analysis, neoadjuvant therapy and transhiatal approach remained significant independent predictors (p < 0.05). The rate of HHBPE was 44% in the 131 patients (51%) that had both factors.

CONCLUSIONS

HHBPE in the current era of neoadjuvant therapy and minimally invasive esophagectomy is common. HHBPE can cause gastrointestinal symptoms, but operation to repair HHBPE is uncommon on intermediate follow-up. Additional study and long-term follow-up are required to fully assess the impact of HHBPE and to potentially modify surgical practice to prevent or minimize HHBPE.

Modified McKeown procedure with uniportal thoracoscope for upper or middle esophageal cancer: initial experience and preliminary results

Background

Uniportal video-assisted thoracic surgery (VATS) resections are of increasing interest in many thoracic surgery departments. With each experience in VATS lobectomy, we have incrementally improved the less invasive techniques in esophagectomy. Here, we report the preliminary results and feasibility of a modified McKeown procedure with uniportal thoracoscopy for upper or middle esophageal cancer in our institution.

Methods

Between March 2015 and May 2016, modified uniportal McKeown procedure with uniportal thoracoscopy for upper or middle esophageal cancer was attempted in 44 patients in our institution.

Results

Of the patients treated with uniportal thoracoscopy and laparoscopy, no patients were converted to open procedures, and all had a complete resection. The mean operative time was 408±34 min (range, 394-495 min). The mean thoracic operation was 163±16 min (range, 135-199 min). The mean blood loss was 245±102 mL (range, 100-450 mL). The mean number of lymph nodes resected was 24 (range, 14-36). The mean ventilator usage of the patients after surgery was 0.3±0.6 days, and the mean intensive care stay was 1.6 days (range, 1 to 7 days). The mean hospital stay was 11.8 days (range, 7 to 22 days). Major complications developed in 2 patients, both of whom had to undergo tracheotomy due to respiratory failure. No patients died of complications postoperatively, and none had clinically significant anastomotic leaks.

Conclusions

Modified McKeown minimally invasive esophagectomy (MIE) with uniportal thoracoscopy seems to be a feasible option for patients with upper or middle esophageal cancer. Larger studies with longer follow-up are needed to further investigate this approach.

Diaphragmatic Hernia Repair After Esophagectomy: Technical Report and Lessons After a Series of Cases

Introduction: Diaphragmatic hernia (DH) repair after esophagectomy is infrequent and technically challenging. Such hernias are mostly asymptomatic and have an estimated incidence of around 2.5%. Controversy continues over suture versus mesh cruroplasty. This article reports a series of cases and a description of the technique, showing this type of procedure being performed in the medical literature and its results. Methods: A DH was diagnosed, and repair was performed in eight out of 328 esophagectomies. All of them were performed through the following steps: (1) Pulling the hernia content down properly without handling the intestinal segment directly to not promote serosal lesions; (2) Lysis of adhesions-this should be done close to the diaphragmatic pillar, with precaution toward the vessels running in the epiplon and near the greater gastric curvature; and (3) Closure of the diaphragmatic hiatus achieved with anterior and posterior sutures. Mesh repair was performed across the DH defects that measured more than 5.5 cm. Results: The patients constituted five men (62.5%) with a mean age of 61.6 years. The main DH-related symptom was abdominal pain, reported by four patients (50%). The other symptoms mentioned were dyspnea (37.5%), thoracic pain (25%), and dysphagia (25%). The mean hospitalization period was 17.5 days and was related to the restoration of the respiratory function. Most of the DH repairs were performed by adopting a laparoscopic approach. Conclusions: DH is a rare complication following esophagectomy with most of the symptomatic manifestations. However, its repair is feasible and safe, with low morbidity (only respiratory complications) and no mortality.

A comparative study of thoracoscopic and open surgery of congenital diaphragmatic hernia in neonates

Background

An increasing number of hospitals have carried out neonatal thoracoscopic assisted repair of congenital diaphragmatic hernia (CDH).

Methods

The 26 cases received thoracoscopic-assisted repair (observation group) and 44 cases open repair (control group). General anesthesia was performed with endotracheal intubation using a trachea cannula without cuff. The general preoperative data, intraoperative hemodynamic parameters, intraoperative surgical conditions, postoperative complications, postoperative recovery condition, postoperative survival rate and recurrence rate were recorded.

Results

The intraoperative mean arterial pressure and heart rate at each time point in observation group were more stable and effective than those in control group (all P <  0.001). The number of manual ventilation, SpO₂ < 90% and hypercapnia cases were significantly lower than those in control group (all P <  0.05). Intraoperative bleeding, incision length and operation duration were significantly lower in observation group compared with control group (all P <  0.001). No significant differences were seen between the two groups in postoperative complications including pulmonary infection, incision infection, pulmonary hypertension, hemorrhage, and scleredema (all P > 0.05). The duration of postoperative mechanical ventilation, antibiotic use and hospitalization in observation group was significantly shorter than those in control group (all P < 0.05). There was no significant difference in postoperative survival rate and recurrence rate between the two groups (both P > 0.05).

Conclusion

The intraoperative hemodynamic parameters of CDH repair under thoracoscopy were more stable, the duration of postoperative mechanical ventilation, antibiotic use and hospitalization were shortened, and the therapeutic effect was better.

Enterothorax After Hepatic Surgery: A Single-Center Experience

BACKGROUND

Enterothorax (ET) is a rare complication after hepatic surgery. The literature in this field is limited and mainly based on case reports. The aim of this study was to review our department's experience.

PATIENTS AND METHODS

We retrospectively analyzed 602 patients who underwent hepatic resection between November 2008 and December 2016. Major hepatic surgery (n = 321) was defined as right or extended right hepatectomy (n = 227), left or extended left hepatectomy (n = 63), trisegmentectomy (n = 13), and living donor liver transplantation (n = 18). ET cases were identified by analyzing clinical courses and radiological imaging.

RESULTS

ET was observed in five out of 602 patients (0.8%). All patients developed the complication after major hepatic surgery (five out of 321, 1.6%). ET exclusively occurred after right (n = 3) or extended right hepatectomy (n = 2). Median time to diagnosis was 22 months. Radiological imaging showed herniation of small (n = 2), large bowel (n = 2), or omental fat (n = 1) with a median diaphragmatic defect of 3.9 cm. Two patients presented with acute incarceration and underwent emergency surgery, one patient reported recurrent pain and underwent elective repair, and two patients refused surgery. Follow-up imaging in two operated patients showed no recurrence of ET after 36 and 8 months.

CONCLUSIONS

Patients after right hepatectomy have a substantial risk of ET. Acute right upper quadrant pain and/or dyspnea after hepatectomy should be investigated with adequate radiological imaging. Elective surgical repair of ET is recommended to avoid emergency surgery in case of incarceration.

Complications After Esophagectomy

Esophagectomy is the mainstay for treating esophageal cancers and other pathology. Even with refinements in surgical techniques and the introduction of minimally invasive approaches, the overall morbidity remains formidable. Complications, if not quickly recognized, can lead to significant long-term sequelae and even death. Vigilance with a high degree of suspicion remains the surgeon's greatest ally when caring for a patient who has recently undergone an esophagectomy. In this review, we highlight different approaches in dealing with anastomotic leaks, chyle leaks, cardiopulmonary complications, and later functional issues after esophagectomy.

Internal hernia to the retrosternal space is a rare complication after minimally invasive esophagectomy: three case reports

Background

Minimally invasive esophagectomy is considered a beneficial approach to esophageal cancer, although a hiatal hernia occurs more frequently in this approach than in open esophagectomy with reconstruction via the mediastinal route. Development of an internal hernia to the retrosternal space is not a recognized complication of reconstruction via the retrosternal route after esophagectomy. We herein report three cases of the development of an internal hernia to the retrosternal space after minimally invasive esophagectomy.

Case presentation

Thoracolaparoscopic esophagectomy with cervical anastomosis by retrosternal route reconstruction was performed in all three cases. All patients were men ranging in age from 60 to 80 years. Two patients had abdominal pain, and one had experienced syncope. All patients were diagnosed by computed tomography with an internal hernia to the retrosternal space and thoracic cavity (retrosternal hernia) without ischemic change to the incarcerated intestine. Two patients received medical therapy to relieve their intra-abdominal pressure, which allowed for a successful reduction of the intestine into the abdomen. Open laparotomy was performed to repair the hernia in the third patient. After reducing the intestine into the abdomen, reefing of the retrosternal orifice was performed, and the gastric conduit was anchored to the abdominal wall. No relapse occurred in three cases throughout follow-up.

Conclusion

Hiatal hernia is a well-recognized complication after minimally invasive esophagectomy; however, retrosternal hernia is a rare complication following this procedure. Based on the present report, if no ischemic change is present in the herniated intestine, two types of potentially curative treatments are available: medical or surgical. As minimally invasive esophagectomy is performed more frequently, retrosternal hernia may become an increasingly more common complication in the near future.

Emergency Laparoscopic Repair of Giant Left Diaphragmatic Hernia following Minimally Invasive Esophagectomy: Description of a Case and Review of the Literature

Postoperative diaphragmatic hernia (PDH) is an increasingly reported complication of esophageal cancer surgery. PDH occurs more frequently when minimally invasive techniques are employed, but very little is known about its pathogenesis. Currently, no consensus exists concerning preventive measures and its management. A 71-year-old man underwent minimally invasive esophagectomy for esophageal cancer. Three months later, he developed a giant PDH, which was repaired by direct suture via laparoscopic approach. A hypertensive pneumothorax occurred during surgery. This complication was managed by the anaesthesiologist through a high fraction of inspired O₂ and several recruitment manoeuvres. The patient remained free of hernia recurrence until he died of neoplastic cachexia 5 months later. Laparoscopic repair of PDH may be safe and effective even in the acute setting and in the case of massive herniation. However, surgeons and anaesthesiologists should be aware of the risk of intraoperative pneumothorax and be prepared to treat it promptly.

Early outcomes of two-stage minimally invasive oesophagectomy in an Australian institution

BACKGROUND

Minimally invasive oesophagectomy (MIO) has a steep learning curve. We report our outcomes of a standardized 25 mm circular-stapled anastomosis using a trans-orally placed anvil (Orvil™). The objective of this study is to report the initial experience of introducing two-stage MIO to an Australian tertiary health service.

METHODS

We describe our consecutive case series of all MIOs performed from a prospectively maintained database. We assessed the morbidity and mortality of MIO at our institution. We compared our first 30 cases to the second cohort of 32 cases.

RESULTS

There were 62 two-stage MIOs performed from 2011 to 2015. The average age was 65 years. Median length of stay was 13 days (5-72 days). Median number of total lymph nodes was 14. Conversion occurred in three patients (5%). Major morbidity was 45%. Delayed gastric emptying 6% (n = 4), pneumonia 6% (n = 4), chyle leak 6% (n = 4), pulmonary embolus 2% (n = 1) and grade II or III anastomotic leak 5% (n = 4). One conduit ischaemia (2%) required reoperation and formation of oesophagostomy. There was one post-operative death within 30 days. There were five post-oesophagectomy hiatal hernias requiring re-operation (8%). There was a significant improvement in operative time (minutes) from the first to second cohort 588 versus 464 (P-value 0.01).

CONCLUSION

The introduction of two-stage MIO to the Australian setting can be safely instituted. Our unit was still within a learning curve after 30 cases.

Mediastinal herniation of the biliary tract leading to bile duct: obstruction following oesophagectomy

Surgical management of oesophageal and gastro-oesophageal junction malignancies is one of the most challenging situations confronting the surgeon. Attaining a complete circumferential resection margin of lower-third oesophageal and gastro-oesophageal junction locally advanced carcinomas requires en-bloc resection of the hiatus and all the peri-oesophageal tissue and pleura. This results in an increased risk of herniation of the abdominal organs through the enlarged hiatus, which carries significant risk of morbidity and mortality. The incidence of this complication is higher than has been reported. Surgical management of symptomatic hernias is the standard treatment while criteria for managing asymptomatic hernias are less clear. We report a rare case of a late mediastinal herniation of the pancreas and bile duct, leading to obstructive jaundice following oesophagectomy which was treated successfully in our unit.
