Safety and efficacy of percutaneous transabdominal and transesophageal decompression gastric catheters for palliation of malignant bowel obstruction

Patient characteristics and procedural and safety outcomes of percutaneous transesophageal gastro-tubing: A nationwide database study in Japan

BACKGROUND

Percutaneous transesophageal gastro-tubing (PTEG) is an alternative interventional procedure in cases where gastrostomy is not feasible. However, the safety and complication rates of PTEG have not yet been evaluated. We aimed to describe the characteristics of patients who underwent PTEG and investigate complications using a nationwide Japanese inpatient database.

METHODS

In this retrospective cohort study, we used the Diagnosis Procedure Combination database in Japan to identify patients who underwent PTEG from April 2012 to March 2020. The outcomes were the occurrence of complications, invasive treatment within 7 days after PTEG, and tube replacement within 14 days after PTEG. We statistically compared patient background, complication rates, and outcomes using PTEG indications.

RESULTS

A total of 3,684 patients underwent PTEG, which was performed in 1,455 patients for decompression and 2,193 patients for feeding. The patients' mean age was 73.1 years, and 62.1% were men. More patients in the decompression group had cancer than those in the feeding group. The overall number of complications was 47 cases (1.3%). The most common treatment administered after PTEG was red blood cell transfusion (3.9%), followed by early tube replacement (3.3%). As invasive treatments for PTEG complications, percutaneous drainage and transcatheter arterial embolization were required in 4 and 1 cases, respectively, and no cases required surgery.

CONCLUSION

We performed a descriptive study on PTEG using a nationwide database in Japan. This study also showed a low complication rate after PTEG in the real world. Our findings provide practical information on the safety of PTEG in Japan.

Percutaneous Image-Guided Transesophageal Long Intestinal Tube Placement for Palliative Decompression in Advanced Cancer Patients with Unresectable Malignant Small Bowel Obstruction

PURPOSE

To assess the safety and efficacy of long intestinal tube placement following percutaneous image-guided esophagostomy for palliative decompression of incurable malignant small bowel obstruction.

MATERIALS AND METHODS

Between January 2013 and June 2022, a single-institution retrospective study was conducted to examine patients undergoing percutaneous transesophageal intestinal intubation for an occluded intestinal segment. Patients' baseline characteristics, procedural details, and clinical courses were reviewed. Severe complications were defined as those with ≥ 4 grade according to the CIRSE classification.

RESULTS

This study included 73 patients (mean age, 57.7 years) who underwent 75 procedures. All bowel obstructions were caused by peritoneal carcinomatosis or similar disease, which precluded transgastric access in almost 50% of the patients due to massive cancerous ascites (n = 28), diffuse gastric involvement (n = 5), or omental dissemination in front of the stomach (n = 3). Technical success (appropriate tube positioning) was achieved in 98.7% (74/75) of procedures. The cumulative 1-month overall survival and sustained clinical success (adequate bowel decompression) rates were estimated at 86.8% and 88%, respectively, using Kaplan-Meier analysis. At the median survival of 70 days, the disease progression required other gastrointestinal interventions, including additional tube insertion, repositioning, or venting enterostomy in 16 patients (21.9%). The severe complication rate was 4% (3/75); one patient aspirated to death due to tube clogging and two encountered fatal perforation of isolated intestinal loops developing far beyond the tip of the indwelling tube.

CONCLUSION

Percutaneous image-guided transesophageal intestinal intubation achieves feasible bowel decompression as palliative care in advanced cancer patients.

Analysis of Placement Priorities and Nursing Countermeasures of Transnasally Inserted Intestinal Obstruction Catheters in Patients with Acute Small Bowel Obstruction

Objective

To explore the placement priorities and analysis of nursing countermeasures of transnasally inserted intestinal obstruction catheters in patients with acute small bowel obstruction (ASBO).

Methods

One hundred and three patients with ASBO treated in our hospital from May 2016 to February 2022 were enrolled to this study. Patients who received individual nursing for transnasally inserted intestinal obstruction catheters were considered as the observation group (n = 59) and those who received traditional nursing were regarded as the control group (n = 44). The symptom relief time, daily gastrointestinal decompression, bowel sound recovery time, exhaust, defecation recovery time, and gas-liquid plane disappearance time were compared between both groups. The abdominal pain was evaluated by visual analogue scale (VAS), and the psychology of patients was evaluated by self-rating anxiety scale (SAS) and self-rating depression scale (SDS). Patients' clinical efficacy and incidence of adverse effects were counted, and quality of life was assessed using the short form 36 (SF-36) health survey questionnaire.

Results

In the observation group, the improvement time of clinical symptoms and VAS, SAS, and SDS scores after intubation were lower than those of the control group, while the total clinical treatment efficiency was higher (P < 0.05). As to the adverse effects, the observation group was lower than the control group (P < 0.05). Also, the SF-36 scores were higher than those of the control group in all dimensions (P < 0.05).

Conclusion

The individual nursing strategy implemented for the transnasally inserted intestinal obstruction catheter can effectively shorten the recovery of ASBO patients and improve their treatment outcome and prognosis quality of life.
