Minimally invasive substernal colonic transposition for corrosive strictures of the upper aerodigestive tract

Changing trends in the minimally invasive surgery for corrosive esophagogastric stricture

Esophagogastric stricture is the troublesome long-term complication of corrosive ingestion with a significant adverse impact on the quality of life. Surgery remains the mainstay of therapy in patients where endoscopic treatment is not feasible or fails to dilate the stricture. Conventional surgical management of esophageal stricture is open esophageal bypass using gastric or colon conduit. Colon is the commonly used esophageal substitute, particularly in those with high pharyngoesophageal strictures and in patients with accompanying gastric strictures. Traditionally colon bypass is performed using an open technique that requires a long midline incision from the xiphisternum to the suprapubic area, with adverse cosmetic outcomes and long-term complications like an incisional hernia. As most of the affected patients are in the second or third decade of life minimally invasive approach is an attractive proposition. However, minimally invasive surgery for corrosive esophagogastric stricture is slow to evolve due to the complex nature of the surgical procedure. With advancements in laparoscopic skills and instrumentation, the feasibility and safety of minimally invasive surgery in corrosive esophagogastric stricture have been documented. Initial series have mainly used a laparoscopic-assisted approach, whereas more recent studies have shown the safety of a total laparoscopic approach. The changing trend from laparoscopic assisted procedure to a totally minimally invasive technique for corrosive esophagogastric stricture should be carefully disseminated to preclude adverse long-term outcomes. Also, well-designed trials with long-term follow-ups are required to document the superiority of minimally invasive surgery for corrosive esophagogastric stricture. The present review focuses on the challenges and changing trends in the minimally invasive treatment of corrosive esophagogastric stricture.

Minimal access surgery of corrosive and thermal strictures of the foregut

BACKGROUND AND AIM

: Conventional surgery for caustic/thermal strictures (CS/TS) entails considerable trauma, which may be mitigated by minimal access surgery (MAS). Experience with its use in CS/TS is both heterogeneous and limited, hence, warrants a comprehensive review.

METHODS

: Medical literature/indexing databases were systematically searched for pertinent articles published in English, from 1990 to 2021, and analysed.

RESULTS

: Fifty relevant articles, pertaining to over 200 patients, were found. They showed that MAS is feasible in CS/TS management. It reduces the access damage in chest and abdomen whilst facilitating resection or bypass of the affected gut segment through different combination of operations, sequence of steps, conduits and routes. The procedures range from completely minimal access to hybrid ones, with reduced complications and faster recovery. Hybrid procedures prove as expeditious as open ones.

CONCLUSIONS

: MAS proves efficacious in restoring alimentary continuity in corrosive/thermal strictures of the foregut.

Surgical management of esophageal stenosis due to ingestion of corrosive substances

BACKGROUND

Corrosive ingestion is a significant challenge for healthcare systems. Limited data are available regarding the best treatments, and there remains a lack of consensus about the optimal surgical approach and its outcomes. This study aims to review the current literature and show a single institution's experience regarding the surgical treatment of esophageal stenosis due to corrosive substance ingestion.

METHODS

A retrospective review that accounted for demographics, psychiatric profiles, surgical procedures, and outcomes was performed. A systematic review of the literature was performed using PubMed.

RESULTS

In total, 27 surgical procedures for esophageal stenosis due to corrosive substance ingestion were performed from 2010 to 2019. Depression and drug abuse were diagnosed in 30% and 22% of the included patients, respectively. Esophagectomies and esophageal bypasses were performed in 13 and 14 patients, respectively. No 30-day mortality was recorded.

CONCLUSION

Surgical intervention either by esophagectomy or esophageal bypass results in durable relief from dysphagia. However, successful clinical outcomes depend on a high-quality multidisciplinary network of esophageal and thoracic surgeons, intensivists, psychologists, psychiatrists, and nutritional teams.

Minimally Invasive Retrosternal Esophageal Bypass Using a Mid-Colon Esophagocoloplasty for Corrosive-Induced Esophageal Stricture

INTRODUCTION

Colonic bypass for corrosive-induced esophageal stricture is traditionally performed using an open approach. The laparoscopic mid-colon retrosternal esophageal bypass has not been previously reported. The present study is aimed to report the feasibility of laparoscopic mid-colon esophagocoloplasty and to compare the short- and medium-term outcomes with the open approach.

MATERIALS AND METHODS

Patients who underwent surgery for corrosive esophageal stricture between August 2016 and August 2019 were retrospectively analyzed. Laparoscopic procedure was preferred in patients with stricture starting at or below the level of cricopharynx and without prior laparotomy. The perioperative and medium-term outcomes of patients who underwent open and laparoscopic mid-colon bypass were compared.

RESULTS

Of the 15 patients, seven patients underwent laparoscopic mid-colon bypass, and eight patients underwent the open procedure. The duration of surgery was less in the laparoscopic group, but the difference was not significant (440 vs. 510 min, P = 0.93). Intraoperative blood loss (median) and postoperative analgesic requirement (median days) were significantly lower in laparoscopic group (200 mL vs. 350 mL, P = 0.03 & 3 vs. 5, P = 0.02). There was no significant difference in the postoperative complications, ICU and hospital stay between the two groups. At a median (range) follow-up of 14 (7-42) months, all patients in the minimally invasive colon bypass group were euphagic to regular Indian diet. Two patients in the open group developed anastomotic stricture requiring endoscopic dilatation.

CONCLUSION

Minimally invasive mid-colon esophageal bypass is a feasible procedure for selected patients with corrosive esophageal stricture with favorable short-term and comparable medium-term outcomes.

Treatment for postchemoradiotherapy hypopharyngeal stenosis: Pharyngoesophageal bypass using an anterolateral thigh flap-A case report

Radiation-induced pharyngoesophageal stenosis is a frequent and unwanted consequence of nonsurgical treatment of hypopharyngeal carcinomas. Current treatment mainly includes endoscopic dilatations, but a poor response to this modality and/or a severe stenosis may lead to a radical resection (pharyngolaryngectomy) and reconstruction with tubed flaps, which allow oral feeding but fail to preserve speech. In this report, we present a case of radiation-induced hypopharyngeal stenosis treated with a pharyngoesophageal bypass using an anterolateral thigh (ALT) flap with the intention of preserving the larynx. We describe the case of a 59-year-old male with severe pharyngoesophageal stenosis after chemoradiotherapy due to a squamous cell carcinoma, where conventional dilatation treatment failed to restore pharyngoesophageal passage of solids or liquids. Since the patient rejected a pharyngolaryngectomy due the loss of speech entailed, a pharyngoesophageal bypass was performed using an ALT flap. The flap measured 13 × 20 cm, which ensured a 4-cm-diameter tube and enough length to communicate the lateral pharyngeal wall with the cervical esophagus. Endoscopy did not reveal flap failure, and during the immediate postoperative period, the patient had a small cervical leak detected only by imaging that did not affect the skin and resolved with antibiotic treatment. The patient also required a tracheostomy on day 4 and initially had no passage of saliva through the bypass; we attributed this to edema that resolved spontaneously after 1 month with complete liquid and solid passage and laryngeal competence that led to tracheal decannulation. Good functional results were achieved both for speech and swallowing at 5-year follow-up. We believe that this procedure may be considered before performing a pharyngolaryngectomy for the treatment of a persistent benign stenosis in patients with a functional larynx.

Transhiatal esophagectomy with gastric pull-up, pyloric exclusion and Roux-en-Y gastroenterostomy for the management of esophageal caustic injury

•

The authors present a surgical option for the management of esophageal caustic injury.

•

The surgery consists of a transhiatal esophagectomy with gastric pull-up, pyloric exclusion and Roux-en-Y gastroenterostomy.

•

The technique can be indicated when esophagectomy is necessary and there is pyloric stenosis associated.

Introduction

Ingestion of caustic materials can lead to digestive tube perforation involving the mouth, pharynx, esophagus and stomach (Vezakis et al., 2016 [1]). In this case report, the authors opted for gastric pull-up in a case of esophageal and pyloric stenosis secondary to caustic ingestion, and a Roux-en-Y gastroenterostomy in the lower portion of the gastric pull-up.

Presentation of case

A 37 years-old male presented complaints of dysphagia, which had started 28 days before admission after the ingestion of a caustic liquid. An esophagogastroduodenoscopy was performed, and showed a complete occlusion of the esophagus, without the possibility of performing an esophagus dilatation or placing a nasoenteric tube. The option was made for a transhiatal esophagectomy with gastric pull-up, pyloric exclusion and Roux-en-Y gastroenterostomy. The patient was later admitted with a stenosis of the esophageal anastomosis, which was resolved after performing endoscopic dilatation.

Discussion

The medical team opted to use the stomach for the reconstruction of the gastrointestinal transit due to less morbidity during manipulation of that organ, as well as safer anastomosis, when compared to the colon. In this case report, the esophagus and pylorus were generally compromised, however, with no apparent damage whatsoever in the stomach. Therefore, we opted to resect the esophagus and used the stomach to perform a gastric pull-up with the exclusion of the pylorus and reconstruction with a Roux-en-Y gastroenterostomy.

Conclusion

The proposed surgery is an option when dealing with similar cases, where endoscopic dilatation is not an option, and there is an associated pyloric stenosis.
