Comparison on the efficacy of EUS-guided celiac plexus radiation and celiac plexus neurolysis in treating abdominal pain of advanced pancreatic cancer / 中华胰腺病杂志

Objective To evaluate the efficacy of endoscopic ultrasonography-guided celiac plexus radiation with iodine-125 (125I) seeds and celiac plexus neurolysis with absolute ethanol for pain relief secondary to advanced pancreatic cancer.Methods A retrospective analysis of 43 patients of advanced pancreatic cancer with moderate to severe abdominal pain in the Department of Gastroenterology,Shanghai Changhai Hospital from January 2017 to April 2018 was performed.20 patients underwent EUS-guided celiac plexus neurolysis (CPN),and 23 patients underwent EUS-guided celiac plexus radiation (CPR) with the implantation of 125I seeds around the celiac ganglia.The postoperative VAS score of abdominal pain,mean analgesic (MS Contin [morphine sulfate]) consumption and complications were compared between the two groups.Results There were no statistically significant differences between the two groups in the sex ratio (male/female,10/10 vs 14/9),average age [(64 ± 11) vs (64 ± 12)],lesion location (head/tail,7/13 vs 8/15] and TNM stage (Ⅲ/Ⅳ,9/11 vs 7/16),and the two groups were comparable.Compared with preoperative ones,the VAS score (3.0 points vs 5.5 points) and morphine dosage (30 mg vs 52.5 mg) were significantly lower in the CPN group one week after operation.In the CPR group,the VAS score (5.0 points vs 6.0 points) and morphine dosage (50 mg vs 55 mg) at 2 weeks after the operation were lower than those before the operation;the VAS scores of 4,8 and 12 weeks after the operation decreased to 3.0 points,and the dosage of morphine decreased to 30 mg,25 mg and 30 mg,respectively.The differences were statistically significant (P＜0.0001).Compared with the CPR group,at 2 weeks postoperatively the CPN group demonstrated a significantly higher decrease of VAS score (3.0 points vs 2.0 points),degree of morphine reduction (30 mg vs 10 mg) and rate of partial pain relief (70.0％ vs 4.3％).However,from 4 to 12 weeks postoperatively,the decrease in VAS score,the decrease in the dosage of MS Contin and the rate of partial pain relief in the CPR group were all significantly higher than those in the CPN group (P ＜ 0.05).There was no complete relief of pain in the two groups.No procedure-related deaths or serious complications were observed and only mild gastrointestinal adverse reactions occurred.Conclusions Two methods can both relieve abdominal pain in patients with advanced pancreatic cancer safely and effectively.CPR takes effect late but has advantages of good extent and long duration of pain relief.

Therapeutic value of endoscopic ultrasound-guided celiac plexus neurolysis for pain associated with advanced pancreatic carcinoma in 29 patients / 中华消化内镜杂志

Objective To evaluate the clinical efficiency of endoscopic ultrasound-guided celiac plexus neurolysis(EUS-CPN)for pain associated with advanced pancreatic carcinoma.Methods EUS-CPN was performed in 29 patients with advanced pancreatic carcinoma in Hangzhou First People′s Hospital from May 2010 to April 2015. The pain status before and after treatment was measured by visual analogue scale (VAS),and the clinical efficacy was assessed by pain anesis rate(PAR). Results All the 29 patients successfully completed EUS-CPN. The mean VAS value of the first day after treatment(3.6±1.5)was lower than that of preoperative(8.2±2.3,P=0.00). The mean VAS value of 1 month after treatment(2.0±0.6) was statistically different compared with the value of the first day after treatment(P=0.00). There were 10, 9,4,and 3 patients who had complete,obvious,moderate and mild relief,respectively. Three patients had no pain relief. The overall efficiency rate was 79.3%(23/29). Conclusion EUS-CPN is a safe and effective method for relieving pain in pancreatic carcinoma.

Intoxicação alcóolica aguda: complicação rara associada a neurólise do plexo celíaco durante procedimento cirúrgico a céu aberto em paciente com dor oncológica refratária. Relato de caso / Acute alcohol intoxication: uncommon complication associated to celiac plexus neurolysis during open surgical procedure in patient with refractory cancer pain. Case report

RESUMO JUSTIFICATIVA E OBJETIVOS: A neurólise do plexo celíaco é uma opção de tratamento da dor para pacientes com câncer abdominal refratário a outras abordagens. É acompanhada de reações adversas que são diagnosticadas e tratadas desde que o paciente receba monitorização e acompanhamento imediato após o procedimento. O objetivo deste estudo foi relatar o caso de uma paciente submetida a neurólise de plexo celíaco, evoluindo com sintomas de intoxicação alcoólica aguda diagnosticada na sala de recuperação pós-anestésica. RELATO DO CASO: Paciente do gênero feminino, 43 anos, com neoplasia de cabeça de pâncreas submetida a neurólise de plexo celíaco intraoperatório com 40mL de álcool a 98%, evolui na sala de recuperação pós-anestésica com hipotensão, hipoxemia e confusão mental, sintomas esses revertidos com hidratação por via venosa e elevação de membros inferiores. CONCLUSÃO: A alcoolização do plexo celíaco bloqueia definitivamente a dor visceral de pacientes com neoplasia de pâncreas, porém não está isenta de reações adversas, as quais podem evoluir para complicações graves caso não sejam prontamente diagnosticadas, tornando-se imprescindível o acompanhamento do paciente na sala de recuperação pós-anestésica.

ABSTRACT BACKGROUND AND OBJECTIVES: Celiac plexus neurolysis is a pain management option for patients with abdominal cancer refractory to other approaches. It is followed by adverse reactions which may be diagnosed and treated, provided patients are monitored and followed up immediately after the procedure. This study aimed at reporting the case of a patient submitted to celiac plexus neurolysis who evolved with acute alcohol intoxication diagnosed in the post-anesthetic care unit. CASE REPORT: Female patient, 43 years old, with pancreatic head cancer, submitted to intraoperative celiac plexus neurolysis with 40 mL of 98% alcohol. Patient evolved in the post-anesthetic care unit with hypotension, hypoxemia and mental confusion, which were reverted with intravenous hydration and elevation of lower limbs. CONCLUSION: Celiac plexus alcoholization permanently blocks visceral pain of pancreatic cancer patients, however it is not free of adverse reactions, which may evolve to severe complications if not promptly diagnosed, making mandatory the follow up of patients in the post-anesthetic care unit.

Development of a new reagent for endoscopic ultrasound-guided celiac plexus neurolysis and tumor ablation therapy

BACKGROUND: Both endoscopic ultrasound-guided celiac plexus neurolysis (EUS-CPN) and tumor ablation using ethanol are very common procedures, and the utility of these therapies has already been reported in prominent journals. However, their effectiveness appears temporary and insufficient, especially EUS-CPN. We therefore have to consider new reagents for improving the results. The present study examined the best concentration of ethanol and povidone iodine mixed with atelocollagen for more effective therapies. METHODS: The effects of the new reagents were confirmed in three live pigs. At first, we injected three kinds of reagents (including indigo carmine) in three separate areas of para-aortic tissue under EUS guidance in one pig. At more than 4 hours after injection, we checked ethanol injection sites after dissection. In next study, we performed EUS-guided injection of a total of six kinds of reagents (two kinds of ethanol, three kinds of povidone iodine, and control atelocollagen) into the livers of two living pigs. After 2 weeks, we examined tissue damage to the liver in the two pigs. RESULTS: The 75% ethanol (absolute ethanol 3.75 mL + 1% atelocollagen 1.25 mL + a very small amount of indigo carmine) was seen like blue gel, and still remained in the para-aortic tissue. Brownish areas of povidone iodine mixed with 3% atelocollagen exhibited clear, regular borders with greatly reduced infiltration into surrounding tissue compared to others. CONCLUSION: We concluded that 75% ethanol mixed with 1% atelocollagen appears optimal for EUS-CPN. Povidone iodine mixed with 3% atelocollagen may be suitable for small tumor ablation therapy.

Hepatic and Splenic Infarction and Bowel Ischemia Following Endoscopic Ultrasound-Guided Celiac Plexus Neurolysis

Endoscopic ultrasound-guided celiac plexus neurolysis (EUS-CPN) is a well-established intervention to palliate malignant pain. We report a patient who developed hepatic and splenic infarction and bowel ischemia following EUS-CPN. A 69-year-old man with known lung cancer and pancreatic metastasis was transferred for debilitating, significant epigastric pain for several months. The patient underwent EUS-CPN to palliate the pain. After the procedure, the patient complained continuously of abdominal pain, nausea, and vomiting; hematemesis and hematochezia were newly developed. Abdominal computed tomography revealed infarction of the liver and spleen and ischemia of the stomach and proximal small bowel. On esophagogastroduodenoscopy, hemorrhagic gastroduodenitis, and multiple gastric ulcers were noted without active bleeding. The patient expired on postoperative day 27 despite the best supportive care.

CT-guided anterior celiac plexus neurolysis by single puncture and 97% alcohol injection has provided effective abdominal pain control and return to daily activities.CONCLUSION: CT-guided celiac plexus neurolysis with single puncture was effective to control abdominal pain in a patient with anal tumor and unresectable liver metastasis.

A Case of Pancreatic Cancer and Opioid Withdrawal after Endoscopic Ultrasound-guided Celiac Plexus Neurolysis / 대한소화기내시경학회지

Pancreatic cancer is usually unresectable upon diagnosis, and treatment aims to optimize the quality of the patient's life by managing symptoms, and, particularly, by providing adequate pain control. When the pain is refractory to opioids, interventions such as celiac plexus neurolysis (CPN) can be considered. Endoscopic ultrasound (EUS)-guided CPN has been introduced for pancreatic cancer. Reported herein is a case of a 75 year-old man with pancreatic cancer who was treated with opioids due to severe abdominal pain. EUS-guided CPN was performed for pain control, and the opioid administration was discontinued as the pain improved dramatically. However, the patient experienced opioid withdrawal symptoms, including anxiety, insomnia, nausea, and vomiting. Thus, although EUS-guided CPN successfully reduced pain in a patient undergoing such treatment and to whom opioid was administered, opioid administration should not be abruptly discontinued. Rather, the opioid dose should be reduced gradually to avoid drug withdrawal.

Clinical study of celiac ganglion block guided by endoscopic ultrasonography on celiac cancer pain / 中华消化杂志

Objective To evaluate the efficacy and salty of endoscopic ultrasonography-guided celiac plexus neurolysis (EUS-CPN) in the treatment of pain due to pancreatic cancer and celiac metastatic carcinoma.Methods Thirty-three patients with celiac carcinoma were selected for EUS-CPN. Among whom 15 pateints were received chemotherapy before procedure . Using endoscopic ultrasounography,transgastric injection of the celiac plexus with bupivacaine and 98% dehydrated absolute alcohol was accomplished.The abdominal pain was evaluated by the numeric pain intensity scale before and at 24,48,72 hours and one week after the precedure.The successful rate of precedure,the complication and the relief of the pain were observed. Results All procedures were performed successfully . No serious complications such as pancreatitis by trauma,pancreatic fistula,bleeding and celiac infection was found.Compared with baseline,pain was significantly relieved at 12,24,72 hours and 1 week after EUS-CPN (100%,98%,90% and 88%,respectively).The pain remission at 24,48,72 hours and one week in patients who received chemotherapy before procedure were 100%,100%,980% and 98%,respectively,while in those who had not treated chemically were 100%,98%,95% and 90%,respectively.The complete%relief of pain in chemotherapy group was significantly higher than that in nonchemotherapy group (75 % vs 56 %,P%0.05).Conclusions EUS CPN is a safe and effective method for relieving pain with low complications.It can raise the quality life of the patients and chemical therapy may be helpful in pain control.
