Electrostimulation for Intractable Delayed Emptying of Intrathoracic Stomach After Esophagectomy

Gastro-Intestinal Disorders and Micronutrient Deficiencies following Oncologic Esophagectomy and Gastrectomy

Primary surgical indications for the esophagus and stomach mainly involve cancer surgeries. In recent years, significant progress has been made in the field of esogastric surgery, driven by advancements in surgical techniques and improvements in perioperative care. The rate of resectability has increased, and surgical strategies have evolved to encompass a broader patient population. However, despite a reduction in postoperative mortality and morbidity, malnutrition remains a significant challenge after surgery, leading to weight loss, muscle mass reduction, and deficiencies in essential nutrients due to digestive complications. Malnutrition worsens quality of life and increases the risk of tumor recurrence, significantly affecting prognosis. Nevertheless, the nutritional consequences following surgery are frequently overlooked, mainly due to a lack of awareness regarding their long-term effects on patients who have undergone digestive surgery, extending beyond six months. Micronutrient deficiencies are frequently observed following both partial and total gastrectomy, as anticipated. Surprisingly, these deficiencies appear to be similarly prevalent in patients who have undergone esophagectomy with iron, vitamins A, B1, B12, D, and E deficiencies commonly observed in up to 78.3% of the patients. Recognizing the distinct consequences associated with each type of intervention underscores the importance of implementing preventive measures, early detection, and prompt management.

Functional syndromes and symptom-orientated aftercare after esophagectomy

BACKGROUND

Surgery is the cornerstone of esophageal cancer treatment but remains burdened with significant postoperative changes of gastrointestinal function and quality of life.

PURPOSE

The aim of this narrative review is to assess and summarize the current knowledge on postoperative functional syndromes and quality of life after esophagectomy for cancer, and to provide orientation for the reader in the challenging field of functional aftercare.

CONCLUSIONS

Post-esophagectomy syndromes include various conditions such as dysphagia, reflux, delayed gastric emptying, dumping syndrome, weight loss, and chronic diarrhea. Clinical pictures and individual expressions are highly variable and may be extremely distressing for those affected. Therefore, in addition to a mostly well-coordinated oncological follow-up, we strongly emphasize the need for regular monitoring of physical well-being and gastrointestinal function. The prerequisite for an effective functional aftercare covering the whole spectrum of postoperative syndromes is a comprehensive knowledge of the pathophysiological background. As functional conditions often require a complex diagnostic workup and long-term therapy, close interdisciplinary cooperation with radiologists, gastroenterologists, oncologists, and specialized nutritional counseling is imperative for successful management.

Gastrointestinal side effects of upper gastrointestinal cancer surgery

In this chapter, we describe the gastrointestinal side effects of oesophagectomy, gastrectomy and pancreaticoduodenectomy for cancer, with a focus on long-term functional impairments and their management. Improvements in upper gastrointestinal cancer surgery have led to a growing group of long-term survivors. The invasive nature of these surgeries profoundly alters the upper gastrointestinal anatomy, with lasting implications for long-term function, and how these impairments may be treated. Successfully maintaining a high quality of survivorship requires multidisciplinary approach, with survivorship care plans focused on function as much as the detection of recurrence.

Delayed Gastric Emptying after Esophagectomy: Management and Prevention

The quality of life associated with eating is becoming an increasingly significant problem for patients who undergo esophagectomy as a result of the improved survival rate after esophageal cancer surgery. Delayed gastric emptying (DGE) is a common complication after esophagectomy. Although several strategies have been proposed for the management and prevention of DGE, no clear consensus exists. The purpose of this review is to present a brief overview of DGE and to help clinicians choose the most appropriate treatment through an analysis of DGE by cause. Furthermore, we would like to suggest some tips to prevent DGE based on our experience.

Gastric Electrical Stimulation Is an Effective Treatment Modality for Refractory Gastroparesis in a Postsurgical Patient with Pancreatic Cancer

Gastroparesis-related hospital visits contribute significantly to healthcare costs. Gastroparesis can lead to chronic symptoms, such as nausea, vomiting, bloating, early satiety, and abdominal pain. It can result in a significant impairment of quality of life. Diabetes and postsurgery are common causes for gastroparesis, but most cases of gastroparesis are idiopathic in presumed etiology. Malignancy-related gastroparesis has also recently been described in the literature, and pancreatic cancer is a malignancy commonly associated with gastroparesis. Whipple surgery for pancreatic cancer is often complicated by gastroparesis during its postoperative course. We report a case where gastric electrical stimulation was an effective treatment option in the treatment of refractory malignancy-related gastroparesis.

Delayed emptying of the gastric conduit after esophagectomy

With increasing survival after esophagectomy for cancer, a growing number of individuals living with the functional results of a surgically altered anatomy calls for attention to the effects of delayed gastric conduit emptying (DGCE) on health-related quality of life and nutritional impairment. We here give an overview of the currently available literature on DGCE, in terms of epidemiology, pathophysiology, diagnostics, prevention and treatment. Attention is given to controversies in the current literature and obstacles related to general applicability of study results, as well as knowledge gaps that may be the focus for future research initiatives. Finally, we propose that measures are taken to reach international expert agreement regarding diagnostic criteria and a symptom grading tool for DGCE, and that functional radiological methods are established for the diagnosis and severity grading of DGCE.

Thoracoscopic Implant of Neurostimulator for Delayed Gastric Conduit Emptying After Esophagectomy

BACKGROUND AND AIMS

Gastroparesis is a clinical syndrome characterized by delayed gastric emptying in the absence of mechanical outlet obstruction. Use of the denervated stomach as an esophageal substitute is a common cause of transient gastroparesis. Gastric electrostimulation through a thoracotomy approach has previously been reported to be effective in patients with medically refractory postesophagectomy gastroparesis. We report the first thoracoscopic implant of a gastric neurostimulator.

METHODS AND RESULTS

A 57-year-old woman underwent Ivor Lewis esophagectomy for early stage (T1N0) adenocarcinoma in 2007. She progressively developed progressive dysphagia, regurgitation, and a 29-kg weight loss. The barium swallow study and upper gastrointestinal endoscopy showed a dilated intrathoracic stomach without evidence of mechanical obstruction. Erythromycin and multiple endoscopic dilatations of the pylorus were unsuccessful, and eventually, a feeding jejunostomy was performed. At the time the patient was referred to our outpatient clinic, she was unable to eat and depended on total enteral nutrition. Computed tomography, endoscopy, and barium swallow study confirmed that there was no evidence of recurrent adenocarcinoma or mechanical gastric outlet obstruction. A gastric electrostimulator system (Enterra(®)) was implanted through a right thoracoscopic access and connected to the gastric conduit. At 6-month follow-up, there was a significant improvement of the total symptom score and quality of life.

CONCLUSIONS

Electrostimulation of the gastric conduit after esophagectomy can safely be performed through a thoracoscopic approach and may represent a reasonable therapeutic option in patients with symptomatic and medically refractory delayed gastric emptying.
