Tube Feed Necrosis after Major Gastrointestinal Oncologic Surgery: Institutional Lessons and a Review of the Literature

Recent Advances in Pancreatic Ductal Adenocarcinoma: Strategies to Optimise the Perioperative Nutritional Status in Pancreatoduodenectomy Patients

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy for which the mainstay of treatment is surgical resection, followed by adjuvant chemotherapy. Patients with PDAC are disproportionately affected by malnutrition, which increases the rate of perioperative morbidity and mortality, as well as reducing the chance of completing adjuvant chemotherapy. This review presents the current evidence for pre-, intra-, and post-operative strategies to improve the nutritional status of PDAC patients. Such preoperative strategies include accurate assessment of nutritional status, diagnosis and appropriate treatment of pancreatic exocrine insufficiency, and prehabilitation. Postoperative interventions include accurate monitoring of nutritional intake and proactive use of supplementary feeding methods, as required. There is early evidence to suggest that perioperative supplementation with immunonutrition and probiotics may be beneficial, but further study and understanding of the underlying mechanism of action are required.

Transgastric Feeding Tube Insertion into the Jejunum after Esophagectomy: Direct Puncture of the Gastric Conduit

PURPOSE

To evaluate the safety and efficacy of percutaneous ultrasound (US)-guided direct puncture of a reconstructed gastric conduit after esophagectomy for performing a percutaneous radiologic gastrojejunostomy.

MATERIALS AND METHODS

Between 2014 and 2020, 26 consecutive patients with esophageal cancer (mean age, 70 years ± 8.3) with a total of 27 attempts of percutaneous radiologic gastrojejunostomy for postsurgical enteral feeding at the National Cancer Center Hospital were included in this study. One patient required a repeat procedure because of persistent anorexia after the removal of the first tube. All patients except 1 had a gastric conduit reconstructed via a retrosternal route. All procedures were performed under local anesthesia with moderate sedation and analgesia. A gastric conduit was directly punctured with an 18-gauge needle under ultrasonographic guidance, followed by feeding tube insertion into the proximal jejunum. Technical details of the procedures, technical success (defined as adequate tube placement), procedure-related complications, and clinical outcomes were reviewed.

RESULTS

The mean procedure time was 25 minutes ± 15, and technical success was obtained in every attempt. Minor complications included mild local pain (n = 7), unintentional tube removal (n = 2), local abdominal wall hematoma (n = 1), and superficial cellulitis (n = 1); no major complications were observed. During a mean follow-up period of 118.3 days ± 85.8, 13 patients resumed oral intake, and the feeding tube could be removed in 4 patients. No procedure-related deaths occurred.

CONCLUSIONS

The US-guided direct puncture technique is feasible for percutaneous gastrojejunal tube insertion in postsurgical patients with esophageal cancer with gastric conduit reconstruction.

Nonocclusive mesenteric ischemia associated with postoperative jejunal tube feeding: Indicators for clinical management

Postoperative nutrition via a jejunal tube after major abdominal surgery is usually well tolerated. However, some patients develop nonocclusive mesenteric ischemia (NOMI). This morbid complication has a grave prognosis with a mortality rate of 41% to 100%. Early symptoms are nonspecific, and no treatment guideline is available. We reviewed cases of NOMI at our institution and cases described in the literature to identify factors that impact the clinical course. Among five patients, three had no necrosis and one had segmental necrosis and perforation. These patients recovered with limited resection and decompression of the bowel and abdominal compartment. In one patient with extended bowel necrosis at the time of re-laparotomy, NOMI progressed and the patient died of multiple organ failure. The extent of small bowel necrosis at the time of re-laparotomy is a relevant prognostic factor. Therefore, early diagnosis and treatment of NOMI can improve the prognosis. Clinical symptoms of abdominal distension, cramps and high reflux plus paraclinical signs of leukocytosis, hypotension and computed tomography findings of a distended small bowel with pneumatosis intestinalis and portal venous gas can help to establish the diagnosis. We herein introduce an algorithm for the diagnosis and management of NOMI associated with jejunal tube feeding.

Nutritional jejunostomy in esophagectomy for cancer, a national register-based cohort study of associations with postoperative outcomes and survival

Purpose

Insertion of a nutritional jejunostomy in conjunction with esophagectomy is performed with the intention to decrease the risk for postoperative malnutrition and improve recovery without adding significant catheter-related complications. However, previous research has shown no clear benefit and there is currently no consensus of practice.

Methods

All patients treated with esophagectomy due to cancer during the period 2006–2017 reported in the Swedish National Register for Esophageal and Gastric Cancer were included in this register-based cohort study from a national database. Patients were stratified into two groups: esophagectomy alone and esophagectomy with jejunostomy.

Results

A total of 847 patients (45.27%) had no jejunostomy inserted while 1024 patients (54.73%) were treated with jejunostomy. The groups were comparable, but some differences were seen in histological tumor type and tumor stage between the groups. No significant differences in length of hospital stay, postoperative surgical complications, Clavien-Dindo score, or 90-day mortality rate were seen. There was no evidence of increased risk for significant jejunostomy-related complications. Patients in the jejunostomy group with anastomotic leaks had a statistically significant lower risk for severe morbidity defined as Clavien-Dindo score ≥ IIIb (adjusted odds ratio 0.19, 95% CI: 0.04–0.94, P = 0.041) compared to patients with anastomotic leaks and no jejunostomy.

Conclusion

A nutritional jejunostomy is a safe method for early postoperative enteral nutrition which might decrease the risk for severe outcomes in patients with anastomotic leaks. Nutritional jejunostomy should be considered for patients undergoing curative intended surgery for esophageal and gastro-esophageal junction cancer.

Is the placement of jejunostomy tubes in patients with esophageal cancer undergoing esophagectomy associated with increased inpatient healthcare utilization? An analysis of the National Readmissions Database

BACKGROUND

Patients undergoing esophagectomy often receive jejunostomy tubes (j-tubes) for nutritional supplementation. We hypothesized that j-tubes are associated with increased post-esophagectomy readmissions.

STUDY DESIGN

We identified esophagectomies for malignancy with (EWJ) or without (EWOJ) j-tubes using the 2010-2015 Nationwide Readmissions Database. Outcomes include readmission, inpatient mortality, and complications. Outcomes were compared before and after propensity score matching (PSM).

RESULTS

Of 22,429 patients undergoing esophagectomy, 16,829 (75.0%) received j-tubes. Patients were similar in age and gender but EWJ were more likely to receive chemotherapy (24.2% vs. 15.1%, p < 0.01). EWJ was associated with decreased 180-day inpatient mortality (HR 0.72 [0.52-0.99]) but not with higher readmissions at 30- (15.2% vs. 14.0%, p = 0.16; HR 0.9 [0.77-1.05]) or 180 days (25.2% vs. 24.3%, p = 0.37; HR 0.94 [0.79-1.10]) or increased complications (p = 0.37). These results were confirmed in the PSM cohort.

CONCLUSION

J-tubes placed in the setting of esophagectomy do not increase inpatient readmissions or mortality.

Successful surgical treatment for nonocclusive mesenteric ischemia of a wide area of the intestine accompanied by gastric conduit necrosis after esophagectomy for esophageal cancer: a case report and review of the literature

BACKGROUND

Nonocclusive mesenteric ischemia (NOMI) has been reported to be a life-threating disease. Gastric conduit necrosis is known as a critical postoperative complication after esophagectomy for esophageal cancer. We encountered a rare case of NOMI of a wide area of the intestine accompanied by gastric conduit necrosis after esophagectomy, which was successfully treated with an emergency operation.

CASE PRESENTATION

A 67-year-old man presented with dysphagia. He was diagnosed with middle thoracic advanced esophageal cancer. After neoadjuvant chemotherapy, he underwent subtotal esophagectomy with lymphadenectomy and gastric conduit reconstruction. On postoperative day (POD) 2, he had diarrhea, high fever, and low blood pressure, which were treated with catecholamines. Laboratory data revealed acidosis and severe sepsis with multi-organ failure, including the kidneys. Although enhanced computed tomography did not exhibit definite findings of bowel ischemia, upper gastrointestinal endoscopy revealed necrotic mucosal changes in the whole gastric conduit. Therefore, we made a diagnosis of septic shock caused by gastric conduit necrosis and performed an emergency operation. When we explored the abdominal cavity, we found not only gastric conduit necrosis but also intermittent necrotic changes in the intestinal wall from the jejunum to the rectum. Therefore, NOMI was diagnosed. We performed an excision of the gastric conduit and 2 m of the small intestine, as well as total colectomy. After the second operation, prostaglandin E1 was administered intravenously as the treatment for NOMI, and sepsis was improved. On POD 122, he was self-discharged. He died of recurrence of lung metastasis from the esophageal cancer 9 months after the first operation.

CONCLUSION

When a patient has a critical status, including severe sepsis or severe acidosis, after esophagectomy, we should consider the possibility of NOMI in addition to gastric conduit necrosis and aim to diagnose and treat it immediately with an urgent operation.

Simplified percutaneous endoscopic transgastric conduit feeding jejunostomy for dysphagia after esophagectomy

Unexpected dysphagia is an important problem affecting life prognosis in patients who have undergone an esophagectomy for esophageal cancer. For nutritional support in patients suffering from dysphagia after a previous esophagectomy, a simplified percutaneous endoscopic transgastric conduit feeding jejunostomy approach was developed that can be performed regardless of the patient's condition. The feasibility of this procedure in 25 patients with esophageal cancer who underwent three-stage esophagectomy with retrosternal gastric conduit reconstruction from April 2009 to December 2016 was evaluated retrospectively. Under fluoroscopy, a percutaneous endoscopic transgastric conduit feeding jejunostomy catheter (9 French) was introduced into the jejunum in the epigastric region using the Seldinger's technique. The following patient data were analyzed retrospectively: operating time, complications, reasons for oral intake difficulty, and clinical data describing patients' nutritional status before and 1 month after percutaneous endoscopic transgastric conduit jejunostomy treatment, such as serum albumin and clinical course. Median patients' age was 68 years (range 50-76 years). Indications for the procedure were late swallowing dysfunction (n = 12), early swallowing dysfunction secondary to surgical complication (n = 8), anastomotic leakage (n = 3), and anorexia (n = 2). Causes of late swallowing dysfunction were radiation injury (n = 8), advanced age (n = 2), or cerebral infarction (n = 2). The median operating time was 29 minutes (range 14-82 minutes). Four patients developed mild erosions at the stoma secondary to bile reflux along the side of the catheter. No patient experienced severe complications such as ileus and peritonitis. Patients were treated for a median of 160 days (range 18-3106 days) with percutaneous endoscopic transgastric conduit jejunostomy. Patient's serum albumin significantly increased from 2.8 to 3.3 g/dl in 1 month. Of the eight patients with early swallowing dysfunction, six successfully regained sufficient oral nutrition after receiving enteral feeding nutritional management. Although all except one late swallowing dysfunction patient could not discontinue tube feeding, five patients were long-term survivors at the time this report was written. This jejunostomy procedure is simple, safe, and useful for patients with unexpected dysphagia and accompanying malnutrition after esophagectomy.

A simple, novel laparoscopic feeding jejunostomy technique to prevent bowel obstruction after esophagectomy: the "curtain method"

BACKGROUND

Feeding jejunostomy (FJ) is a common treatment to support patients with esophageal cancer after esophagectomy. However, severe FJ-related complications, such as bowel obstruction, occasionally occur. We investigated the ability of our simple, novel FJ technique, the "curtain method," to prevent bowel obstruction.

METHODS

In laparoscopic surgery, the main mechanism of bowel obstruction involves torsion of the mesentery accompanied by migration of the intestine across the fixed FJ through the space surrounded by a triangle comprising the ligament of Treitz, fixed FJ, and spleen rather than adhesion. Our "curtain method" involves closure of this triangle zone with omentum, and the appearance of the lifted omentum resembles a curtain. Sixty patients treated with this modified FJ were retrospectively compared with 13 patients treated with conventional FJ in terms of the incidence of bowel obstruction, peritonitis, stoma site infection, and catheter obstruction.

RESULTS

From 2013 to 2017, 60 patients underwent esophagectomy and gastric conduit reconstruction accompanied by modified laparoscopic FJ. The median observation period, including the period after tube removal, was 644 days. No FJ-associated bowel obstruction, the prevention of which was the primary aim, occurred in any patient. Likewise, no peritonitis or dislodgement occurred. Eight patients (13%) developed a stoma site infection with granulation. The feeding tube became occluded in 11 patients (18%); however, a new feeding tube was reinserted under fluoroscopy for all of these patients. From 2003 to 2012, 13 patients underwent conventional FJ. The median observation period was 387 days. Three patients (23%) developed bowel obstruction by torsion 71 to 134 days after the first surgery, and all were treated by emergency operations. Other FJ-related complications were not different from those in the modified FJ group.

CONCLUSION

Our simple, novel technique, the "curtain method," for prevention of laparoscopic FJ-associated bowel obstruction after esophagectomy is a safe additional surgery.

Optimal timing and route of nutritional support after esophagectomy: A review of the literature

Some controversy surrounds the postoperative feeding regimen utilized in patients who undergo esophagectomy. Variation in practices during the perioperative period exists including the type of nutrition started, the delivery route, and its timing. Adequate nutrition is essential for this patient population as these patients often present with weight loss and have altered eating patterns after surgery, which can affect their ability to regain or maintain weight. Methods of feeding after an esophagectomy include total parenteral nutrition, nasoduodenal/nasojejunal tube feeding, jejunostomy tube feeding, and oral feeding. Recent evidence suggests that early oral feeding is associated with shorter LOS, faster return of bowel function, and improved quality of life. Enhanced recovery pathways after surgery pathways after esophagectomy with a component of early oral feeding also seem to be safe, feasible, and cost-effective, albeit with limited data. However, data on anastomotic leaks is mixed, and some studies suggest that the incidence of leaks may be higher with early oral feeding. This risk of anastomotic leak with early feeding may be heavily modulated by surgical approach. No definitive data is currently available to definitively answer this question, and further studies should look at how these early feeding regimens vary by surgical technique. This review aims to discuss the existing literature on the optimal route and timing of feeding after esophagectomy.

Non-occlusive mesenteric ischemia associated with enteral feeding after esophagectomy for esophageal cancer: report of two cases and review of the literature

Background

Non-occlusive mesenteric ischemia (NOMI) is a rare but life-threatening complication of early postoperative enteral feeding. We herein report two patients who developed NOMI during enteral feeding after esophagectomy.

Case presentation

In case 1, a 75-year-old man with no medical history was diagnosed with multiple primary cancers of the esophagus, stomach, and kidney. He underwent percutaneous endoscopic gastrostomy tube placement followed by thoracoscopic esophagectomy and cervical esophagostomy placement as the first-stage operation. Gastrostomy feeding was started on postoperative day (POD) 3 with a polymeric formula (ENSURE H®). On POD 7, he developed acute abdominal pain and distension with bloody drainage through the gastrostomy tube. Dynamic computed tomography showed massive hepatic portal venous gas and pneumatosis intestinalis. Angiography showed diffuse spasms in the branches of the superior mesenteric artery. Under a diagnosis of NOMI, we started intra-arterial infusion of papaverine and prostaglandin E1. His symptoms improved, and he was discharged on POD 48.

In case 2, a 68-year-old man with diabetes and atrial fibrillation was diagnosed with esophageal cancer. His medical history was significant for pylorus-preserving gastrectomy for gastric cancer and small bowel resection for trauma. He underwent thoracoscopic esophagectomy, open total gastrectomy, colonic reconstruction, and jejunostomy tube placement. Adhesiolysis for abdominal severe adhesions caused by previous operations was difficult. Jejunostomy feeding was started on POD 3 with a polymeric formula (Racol®). On POD 7, he developed persistent diarrhea and cervical anastomotic leakage. On POD 9, he developed acute abdominal pain and distension with bloody drainage through the jejunostomy tube. Dynamic computed tomography showed the same findings as in case 1. Under a diagnosis of NOMI, we started intravenous infusion of papaverine and prostaglandin E1. His symptoms improved, and he was discharged on POD 28.

Conclusions

The causes of feeding-related NOMI may include the use of a high-osmolarity formula, preoperative malnutrition, abdominal adhesiolysis, systemic inflammation after anastomotic leakage, and a medical history of diabetes and atrial fibrillation. NOMI should be considered as a differential diagnosis in patients with these risk factors and clinical features such as acute abdominal pain and distension during enteral feeding.
