Novel reconstruction using pedicled ileocolic interposition with intrathoracic esophago-ileal anastomosis after distal esophagectomy for esophagogastric junction cancer: A report of two cases.

There is no optimal reconstruction after radical distal esophagectomy for cancers of the esophagogastric junction. We designed a novel reconstruction technique using pedicled ileocolic interposition with intrathoracic anastomosis between the esophagus and the elevated ileum. Two patients underwent the surgery. Case 1 was a 70-year-old man with esophagogastric junction adenocarcinoma with 3 cm of esophageal invasion. Case 2 was a 70-year-old man with squamous cell carcinoma of the esophagogastric junction; the epicenter of which was located just at the junction. These two patients underwent radical distal esophagectomy and pedicled ileocolic interposition with intrathoracic anastomosis. They were discharged on postoperative days 17 and 14, respectively, with no major complication. Pedicled ileocolic interposition is characterized by sufficient elevation and perfusion of the ileum, which is fed by the ileocolic artery and vein. As a result, we can generally adapt this reconstruction method to most curable esophagogastric junction cancers.

Conduit Selection for Reconstruction After Esophagectomy for Esophageal Cancer.

The reconstruction of the esophagus after esophagectomy presents many technical and management challenges to surgeons. An effective gastrointestinal conduit that replaces the resected esophagus must have adequate length to reach the upper thoracic space or the neck, have robust vascular perfusion, and provide sufficient function for an adequate swallowing mechanism. The stomach is currently the preferred conduit for esophageal reconstruction after esophagectomy. However, there are circumstances, where the stomach cannot be utilized as a conduit. In these cases, an alternative conduit must be considered. The current alternative conduits include colon, jejunum, and tubed skin flaps.

Advanced chemo- and radiotherapy makes it possible to expand the cohort of patients who can undergo surgical treatment for esophageal cancer. Optimization of perioperative approach, diagnosis and modern options for complications reduced early postoperative mortality after esophagectomy. Conduit ischemia with failure of esophageal-gastric or esophageal-intestinal anastomosis is one of the most serious complications. To minimize the risk of anastomotic leakage and graft necrosis in these patients, various methods of intraoperative assessment of graft viability are being investigated. Near-infrared fluorescence imaging with indocyanine green is valuable for real time assessment of graft perfusion. To date, fluorescence imaging is analyzed regarding perfusion of the gastric stalk after esophagectomy. However, there are still few or no data on this method for analysis of colonic conduit perfusion. The absence of plastic material for gastrointestinal reconstruction is the most dangerous moment in case of ischemia and necrosis of colonic graft. We present our first case of delayed retrosternal esophageal repair using intraoperative indocyanine green fluorescence imaging for assessment of conduit perfusion.

Salvage reconstruction of the esophagus using the left colon with microscopic supercharge following failed ileocolic reconstruction: A case report.

INTRODUCTION: Ileocolic interposition is often used for the reconstruction of patients with esophageal cancer with a history of gastrectomy. However, graft failure due to conduit necrosis has been reported in 0-5 % of patients. Salvage reconstruction surgery for this situation is considered challenging, and only a few cases of successful salvage operations following failure of ileocolic interposition have been reported. PRESENTATION OF CASE: A 70s year-old male patient with a history of distal and total gastrectomy underwent subtotal esophagectomy for esophageal cancer. Reconstruction using a pedicled ileocolic interposition was performed; however, the ileocolic graft failed. After recovery of the nutritional status, salvage reconstruction was planned. Due to a history of Roux-en-Y reconstruction for gastric cancer, jejunal reconstruction was not considered feasible. Therefore, salvage reconstruction was performed using left colon interposition with microscopic supercharge and superdrainage anastomosis. The graft was pedicled by the left colic artery and the inferior mesenteric vein, and microscopic anastomosis was performed between the intrathoracic and middle colic vessels. The patient recovered without major complications and retained the ability to consume normal food. DISCUSSION: Microscopic supercharge and superdrainage vascular anastomosis have been reported to ensure augmented blood flow. This is the first case report of successful salvage reconstruction using the left colon interposition technique following failure of ileocolic interposition for esophageal cancer. CONCLUSION: We report a case of salvage reconstruction using left colon interposition with microscopic supercharge and superdrainage anastomosis following failure of ileocolic reconstruction for esophageal cancer.

Two Cases of Robot-Assisted Totally Minimally Invasive Esophagectomy with Colon Interposition for Gastroesophageal Junction Cancer: Surgical Considerations.

This case report presents 2 patients with gastroesophageal junction cancer who both underwent totally minimally invasive esophagectomy with colon interposition. Patients 1 and 2, who were 43-year-old and 78-year-old men, respectively, had distinct clinical presentations and medical histories. Patient 1 underwent minimally invasive robotic esophagectomy with a laparoscopic total gastrectomy, colonic conduit preparation, and intrathoracic esophago-colono-jejunostomy. Patient 2 underwent completely robotic total gastrectomy, colon conduit preparation, and intrathoracic esophago-colono-jejunostomy. The primary challenge in colon interposition is assessing colon vascularity and ensuring an adequate conduit length, which is critical for successful anastomosis. In both cases, we used indocyanine green fluorescence angiography to evaluate vascularity. Determining the appropriate conduit is challenging; therefore, it is crucial to ensure a slightly longer conduit during reconstruction. Because totally minimally invasive colon interposition can reduce postoperative pain and enhance recovery, this surgical technique is feasible and beneficial.

Gastric tube perforation penetrating the pericardium after esophagectomy that needed surgical repair.

Background: As the prognosis of esophageal cancer surgery has improved, reports on postoperative complications of gastric tubes have increased. Among them, gastric tube ulcer perforation is infrequent but often severe and difficult to treat. Case Presentation: A 73-year-old man had undergone thoracoscopic subtotal esophagectomy and laparoscopic-assisted gastric tube reconstruction via the retrosternal route for thoracic esophageal cancer 8 years previously. He was transferred to our hospital with a diagnosis of gastric tube ulcer perforation, penetrating the pericardium. Emergency surgery was performed to remove the gastric tube, followed by immediate reconstruction by right colon interposition. The patient was discharged on postoperative day 142. Conclusion: We report a rare complication of gastric tube ulcer perforation, penetrating the pericardium, after esophagectomy for esophageal cancer. It was successfully treated with appropriate surgical management.

The role of intraoperative hyperspectral imaging (HSI) in colon interposition after esophagectomy.

BACKGROUND: Colon conduit is an alternative approach to reconstructing the alimentary tract after esophagectomy. Hyperspectral imaging (HSI) has been demonstrated to be effective for evaluating the perfusion of gastric conduits, but not colon conduits. This is the first study to describe this new tool addressing image-guided surgery and supporting esophageal surgeons to select the optimal colon segment for the conduit and anastomotic site intraoperatively. PATIENTS AND METHODS: Of 10 patients, eight who underwent reconstruction with a long-segment colon conduit after esophagectomy between 01/05/2018 and 01/04/2022 were included in this study. HSI was recorded at the root and tip of the colon conduit after clamping the middle colic vessels, allowing us to evaluate the perfusion and appropriate part of the colon segment. RESULTS: Anastomotic leak (AL) was detected in only one (12.5%) of all the enrolled patients (n = 8). None of the patients developed conduit necrosis. Only one patient required re-anastomosis on postoperative day 4. No patient needed conduit removal, esophageal diversion, or stent placement. There was a change in the anastomosis site to proximal in two patients intraoperatively. There was no need to change the side of colon conduit intraoperatively in any patient. CONCLUSION: HSI is a promising and novel intraoperative imaging tool to objectively assess the perfusion of the colon conduit. It helps the surgeon to define the best perfused anastomosis site and the side of colon conduit in this type of operation.

The Novel Conduit: Challenges of Esophagectomy After Bariatric Surgery.

Metabolic surgery has been on the rise over the last 2 decades. As more literature has been being published regarding its efficacy in treating metabolic syndrome as well as advancements in surgical training and safety rise with it, metabolic surgery will in no doubt continue to increase in prevalence. Concomitantly, the prevalence of esophageal cancer is increasing. We present two cases of patients who are status post sleeve gastrectomy and require esophagectomy. These patients do not have the availability of a gastric conduit, and colon interposition graft was planned for their reconstructions. We here review the two unique case scenarios as well as an overview of colon interposition technique and workup considerations. The need this reconstruction technique will likely increase in the years to come and metabolic surgery and esophageal cancer both continue to rise.

Colon Interposition for Esophageal Cancer.

Esophagectomy and colon interposition in the adult patient, either for primary alimentary reconstruction or as a secondary replacement after initial resection/reconstruction for malignant or benign disease, remains a valuable tool in the thoracic surgeon's armamentarium. It is important for surgeons to remain versed in the complexities of the operation, including preoperative preparation and decision making, operative procedural and technical variations, and recognition and timely treatment of postoperative complications. In this article, we present technical details of the procedure, a review of selected published studies, long-term results, and indications and outcomes for revisional surgery.

A case report of primary gastroesophageal melanoma: Presentation, diagnosis, and surgical approach.

Introduction & importance: Gastrointestinal tract is an uncommon site for primary melanoma and its annual incidence is reported 0.47 cases in million. Thus, limited information is available about its medical or surgical treatment, long-term complications of melanoma, and survival rates of each therapeutic method. Case presentation: A 47-year-old male was admitted to the emergency department with massive rectorrhagia. with not notable medical history except recent episodes of dyspepsia, melena, malaise and weight loss. Melena and weight loss in a 47-year-old patient is considered as suspicious signs for malignancy and should be investigated. The patient was finally diagnosed with primary gastrointestinal melanoma (PGIM). He underwent trans-hiatal total esophagectomy and proximal gastrectomy with gastric pull-up and lymph node dissection. Immunotherapy with Interferon-α was chosen as adjuvant therapy for this patient. After 10 months, CT scan of abdomen with intravenous and oral contrast revealed multiple foci in liver and spleen consistent with metastasis without any evidence of recurrence at primary tumor excision site. Clinical discussion: In this article, we presented a rare case of PGIM with later metastasis in liver and spleen. Gastric pull up was preferred to colon interposition for conduit reconstruction after esophagectomy in this case. However due to the rarity of this category of tumor more information must be gathered on the amount of margin to be resected and long-term outcome of different surgical approaches. Conclusion: Based on the poor prognosis of PGIM, less invasive surgical procedure which provides the radical resection and adequate onco-surgical dissection should be considered.

Nutritional benefit of remnant gastric preservation in patients with esophageal cancer undergoing radical esophagectomy and ileo-colon interposition.

BACKGROUND: This retrospective study aimed to investigate the short-term surgical outcomes and nutritional status of ileo-colon interposition in patients with esophageal cancer who could not undergo gastric tube reconstruction. METHODS: Sixty-four patients underwent subtotal esophagectomy with reconstruction using ileo-colon interposition for esophageal cancer at the Wakayama Medical University Hospital between January 2001 and July 2020. Using propensity scores to strictly balance the significant variables, we compared treatment outcomes. RESULTS: Before matching, 18 patients had cologastrostomy and 46 patients had colojejunostomy. After matching, we enrolled 34 patients (n = 17 in cologastrostomy group, n = 17 in colojejunostomy group). Median operation time in the cologastrostomy group was significantly shorter than that in the colojejunostomy group (499 min vs. 586 min; P = 0.013). Perforation of the colon graft was observed in three patients (7%) and colon graft necrosis was observed in one patient (2%) in the gastrojejunostomy group. Median body weight change 1 year after surgery in the cologastrostomy group was significantly less than that of the colojejunostomy group (92.9% vs. 88.5%; P = 0.038). Further, median serum total protein level 1 year after surgery in the cologastrostomy group was significantly higher than that of the colojejunostomy group (7.0 g/dL vs. 6.6 g/dL, P = 0.030). CONCLUSIONS: Subtotal esophagectomy with reconstruction using ileo-colon interposition is a safe and feasible procedure for the patients with esophageal cancer in whom gastric tubes cannot be used. Cologastrostomy with preservation of the remnant stomach had benefits in the surgical outcomes and the postoperative nutritional status.

Voice Outcomes Following Colon Interposition.

SIGNIFICANCE STATEMENT: This case highlights the consequences of colon interposition on phonation and swallowing. Findings in this patient included laryngopharyngeal reflux, vocal fold paralysis, poor esophageal peristalsis, failed bolus transfers, and others. The mechanical and functional differences between the colon and the esophagus can impact bolus transfer, reflux, and phonation. Further research is required to identify the mechanisms by which colon interposition can impact voice and swallowing.

Microvascular grafting to enhance perfusion in colonic long-segment oesophageal reconstruction.

PURPOSE: Oesophagectomy with long-segment colon reconstruction is the first-line treatment when the stomach is not available. Supercharging of the newly formed conduit can improve vascular function utilizing intraoperative perfusion imaging system, following thoracoscopic oesophagectomy for distal-oesophageal and gastroesophageal junction cancer. The purpose of this study is to examine the safety and efficacy of microvascular augmentation of left colonic interposition following oesophagectomy for oesophageal cancer. METHODS: A retrospective analysis of 156 consecutive oesophagectomies between January 2016 and July 2018 was performed. All oesophagectomies involving left colon interposition with microvascular augmentation were included in the study. In all cases, oesophageal mobilization was performed thoracoscopically in prone position and the left colon was used as neo-oesophagus in an isoperistaltic fashion. Conduit perfusion was assessed with the Spy system and neck supercharging was performed using microsurgical technique. RESULTS: A total of n = 5 (3.2%) patients were identified. Two cases had delayed and 3 had immediate reconstruction. The conduit was microsurgically augmented in 3 cases with both venous and arterial anastomoses (supercharging) and in 2 cases with venous anastomosis only (superdrainage). No anastomotic leak was identified. One case developed left recurrent laryngeal nerve palsy with associated aspiration pneumonia. CONCLUSIONS: Supercharged colonic interposition is a safe way of oesophageal reconstruction when long-segment interposition graft is needed. In oesophageal cancer and in the absence of a viable stomach with intact gastroepiploic arcade, it should be considered a feasible option with favourable outcomes, when the expertise and facilities are available. Use of intraoperative perfusion imaging reveals improved conduit blood supply post-supercharging.

How to ensure immediate and long-term good blood supply by the careful dissection of the marginal artery and supercharge with neck vessels in esophageal reconstruction with the colon segment interposition: 35 years of experience.

BACKGROUND: Colon interposition for total esophageal replacement cases represents one of the most challenging procedures in surgery. A retrospective study has been conducted and suggestions are proposed according to the analysis of 268 patients who underwent colon interposition for esophageal replacement. Complication rates and the duration of hospital stay were retrospectively analyzed. METHODS: A total of 268 patients were operated between 1984 and 2018. In group 1, 164 patients underwent colon interposition without supercharging with neck vessels and in group 2, 104 patients underwent colon interposition with supercharging. Data regarding flap loss, anastomotic leakage, the duration of hospital stay, and stricture formation in the long-term were statistically analyzed and compared between two groups. RESULTS: The success rate of reconstruction was 98,1% (161 of 164 patients) and 99% (103 of 104 patients) for group 1 and 2, respectively. Early complication (anastomotic leakage) rate was 4,9% in group 1 and 1% in group 2. The differences between two groups regarding flap loss and anastomotic leakage rates were not statistically significant (p = 0,495 and p = 0,077, respectively). The hospital stay was 26,3 days for patients without supercharging (group1) and 20,5 days for patients with supercharging (group 2). In group 1, 6,7% (11/164) of patients had narrowing at the junction of the pharynx and colon; however, in group 2, proximal anastomotic stricture formation was observed in only 1% (1/104) of the patients. The stricture rate was significantly lower in group 2 when compared to group 1 (p = 0,021). CONCLUSION: The careful dissection of the marginal artery and supercharging with neck vessels provide lower complication rates in colon interposition for esophageal reconstruction.

Colonic interposition, a contemporary experience: technical aspects and outcomes.

Colonic interposition is rarely used as an oesophageal replacement after resection, as the preferred use of stomach involves less anastomoses and lower risks of major complications. The functional outcome from the colonic conduit is also unpredictable. This report documents the spectrum of experience of a high-volume oesophageal centre, highlighting indications, techniques and functional outcomes. A retrospective review was undertaken of a prospective database from 2012 to 2016. Four of 252 (1.5%) cases in this time period utilised colon interposition. Two cases were for gastric conduit necrosis following oesophageal cancer resections, one for caustic ingestion with both an oesophago-bronchial fistula and gastric injury, and one for a primary oesophageal malignancy in a patient whom previously had a total gastrectomy. All patients had either a retrosternal or posterior mediastinal isoperistaltic right colon conduit placed. Two of three cancer patients are alive and disease free at 3 and 5 years, respectively. Surviving patients are weight stable and tolerating a normal diet. Both report excellent quality of life using validated assessment tools. Colonic interposition is rarely required in modern oesophageal practice, but with this technique good long-term nutritional and functional outcomes can be obtained. It is required in the armamentarium of a specialist centre, and training given its rarity may require novel approaches such as simulation and cadaveric-based training.

Transhiatal isoperistaltic colon interposition without cervical oesophagostomy in long-gap oesophageal atresia.

BACKGROUND: Oesophageal colonic interposition in oesophageal atresia (OA) patients is almost exclusively done as a staged operation with an initial oesophagostomy and gastrostomy followed by the definitive surgery months later. This study presents a series of patients in whom a cervical oesophagostomy was not performed before the substitution surgery. PATIENTS AND METHODS: Records of EA patients were evaluated for those who underwent colon interposition without cervical oesophagostomy. RESULTS: There were five patients: three with pure EA and two with proximal tracheo-oesophageal fistula. A delayed primary repair could not be performed because of intra-abdominally located distal pouch. The mean age at the time of definitive operation was 5.54 (±2.7) months and the mean weight was 6.24 (±1.3) kg. A right or a left colonic segment was used for interposition keeping the proximal anastomosis within the thorax. The post-operative results were quite satisfactory within a median follow-up period of 33.2 months. CONCLUSION: Avoiding cervical oesophagostomy and its inherent complications and drawbacks is possible in a subset of patients with long-gap EA who underwent colonic substitution surgery. This approach may be seen as an extension of the consensus that the native oesophagus should be preserved whenever possible, because it uses the native oesophagus in its entirety.

Magnetic compression anastomosis is effective in treating stenosis after esophageal cancer surgery: a case report.

BACKGROUND: Esophagostomy is important in the treatment of esophageal cancer. However, esophagectomy has a higher risk of postoperative complications. Treatment for complications is often difficult, and in some cases, oral intake is no longer possible. Recently, magnetic compression anastomosis (MCA) was developed; it is a relatively safe method of anastomosis that does not require surgery in patients with stricture, obstruction, or dehiscence of the anastomosis after surgery. CASE PRESENTATION: The patient was a 76-year-old Japanese man. He underwent esophagectomy with a three-field dissection for esophageal cancer. A cervical esophagostomy and chest drainage were performed for necrosis of the gastric tube. Following infection control, colon interposition was performed. However, after the operation, the colon necrotized and formed an abscess. Drainage controlled the infection, but the colon was completely obstructed. The patient was referred to our hospital to restore oral ingestion. Contrast studies showed that the length of the occlusion was 10 mm. The reconstruction was examined; reanastomosis by surgery was judged to be a high risk, so the strategy of anastomosis by MCA was adopted. In the operation, the anterior chest was opened to expose the colon, and a magnet was inserted directly into the blind end of the colon. The magnet was guided to the blind end of the esophagus using an oral endoscope. Two weeks after MCA, a contrast study confirmed the passage of the contrast agent from the esophagus to the colon. The patient eventually took 18 bougies after the MCA. However, since then, he has not needed a bougie. As of 1 year and 8 months after the MCA, the patient is living at home with oral intake restored. CONCLUSIONS: MCA is an effective and safe treatment for complete stenosis after esophageal cancer surgery.

Frequency of Polyps and Adenocarcinoma in Colon Interposition After Esophagectomy in Adulthood - A Systematic Review.

BACKGROUND/AIM: Colon interposition counts among the most common techniques for reconstruction after esophagectomy. Availability of data on metachronous mucosal pathologies is weak. The aim of this review was to identify all reports on the development of metachronous adenoma and adenocarcinoma in colon interposition after esophagectomy in adulthood. MATERIALS AND METHODS: A comprehensive search was conducted in MEDLINE/PubMed, Science Direct, Cochrane Library, Bayerische Staatsbibliothek München. All studies reporting on patients who received colon interposition as substitute after esophagectomy in adulthood for benign and malignant reasons were included. RESULTS: Five retrospective studies were included, reporting on 1016 patients. Therein, no interval lesion was identified. One further study, which formally must be excluded for a misfit to inclusion criteria reports on three interval carcinomas within 365 patients. Because these lesions were the only ones found within a cohort analysis, results were supplementary reported in this review. Additionally, 31 case reports including 32 patients with benign (n=7) or malignant (n=25) findings were analyzed. Median age was 63.5 years (interval carcinoma) and 69 years (benign lesion). Benign and malignant lesions were diagnosed after a median of 8.5 years. CONCLUSION: Due to the rareness of respective cohort studies, the frequency of metachronous lesions cannot be calculated accurately. The estimated rate of interval carcinoma is 0-0.22%. Life-long endoscopic surveillance of patients with colon interposition is recommended.

Gut Entrapped in the Thorax: A Rare Presentation of Abdominal Pain in Chilaiditi Syndrome.

Chilaiditi syndrome is a rare disorder comprising of the interposition of the gut between the diaphragm and liver. This can lead to a spectrum of gastrointestinal and respiratory presentations, primarily in the elderly population in whom the disorder is relatively more prevalent. We present a case of a 63-year-old man who presented to our setup with abdominal pain and shortness of breath and later got diagnosed with Chilaiditi syndrome. He was managed conservatively and showed complete resolution of the symptoms.
