[Persistent hiccups after perforated cholecystitis]. / Vedvarende hikke etter perforert kolecystitt.

BACKGROUND: Persistent hiccups lasting more than 48 hours are rare and have numerous possible causes that require further investigation. CASE PRESENTATION: We present a man in his seventies who was admitted to hospital after 11 days of hiccups. The hiccups were preceded by abdominal pain that spontaneously receded after a few hours. At admission he had no abdominal pain during examination, but a CT scan later suggested that the cause was a perforated cholecystitis with an intra-abdominal abscess. The abscess was drained percutaneously and treated with antibiotics, and the hiccups stopped. INTERPRETATION: Persistent hiccups warrant thorough examination, and it is recommended to consider CT scans of the head and truncus, cerebral MRI scan and an upper GI endoscopy. Treating the underlying cause of hiccups is the ultimate target, while symptomatic treatment simultaneously is preferred.

[Chronic hiccups: diagnosis and treatment]. / Hoquet chronique : diagnostic et traitement.

Chronic hiccups, lasting more than 48 hours, are a medical condition that remains challenging in both diagnosis and treatment. They can be the sole symptom of a serious underlying disorder, and should therefore not be overlooked, although gastroesophageal reflux disease (GERD) constitutes their most prevalent cause. Chronic hiccups mandate a comprehensive etiological assessment. Treatment strategy may include physical, pharmacological and interventional approaches, as described in literature, particularly when direct causal treatment is unattainable.

Le hoquet chronique, de plus de 48 heures, est une entité dont la prise en charge est souvent méconnue. Il ne doit pas être négligé parce qu'il peut être le seul symptôme d'une maladie sous-jacente grave, même si le reflux gastro-œsophagien (RGO) en est la cause la plus fréquente. Face à un hoquet chronique, un bilan étiologique doit donc être effectué. Dans les cas où un traitement causal n'est pas envisageable, plusieurs possibilités de traitements physiques, médicamenteux et interventionnels sont décrites dans la littérature.

Intractable hiccups after VNS implantation: a case report.

BACKGROUND: Hiccups (medically termed, "singultus"), when intractable, can cause significant medical consequences such as aspiration, malnutrition, and depression, leading to poor quality of life. Several case reports have shown that vagus nerve stimulator (VNS) implantation can help treat central idiopathic intractable hiccups. However, we present a contrary case of a patient who developed intractable singultus following VNS placement for medically refractory epilepsy. CASE PRESENTATION: We report a 71-year-old male patient with drug-resistant epilepsy who underwent VNS implantation and developed intractable hiccups shortly thereafter. The hiccups were severe and persistent, such that the patient developed a Mallory-Weiss tear, which required intensive care, invasive intubation and mechanical ventilation, and a prolonged rehabilitation course. Despite multiple therapies including phrenic nerve block and Nissen fundoplication, the patient's hiccups persisted and only stopped once the VNS was permanently deactivated. CONCLUSIONS: Little is known about the incidence of hiccups after VNS implantation. We present one case of hiccups as a direct consequence of VNS implantation. The clinical impact of this report is significant given the relative unfamiliarity of hiccups as an adverse effect of VNS implantation. Neurologists and epileptologists, who present VNS implantation as a surgical option for seizure control to their patients, should be aware of the possibility of singultus development and its significant physical and emotional ramifications.

Perspectives on the Medical, Quality of Life, and Economic Consequences of Hiccups.

PURPOSE OF REVIEW: Singultus or hiccups (HU) is a common, usually temporary, event. Its potentially serious consequences are often overlooked. This review explores published evidence describing HU burden (clinical, economic, and quality of life [QoL] consequences) across patient populations. RECENT FINDINGS: Literature review identified 81 articles (including 57 individual case reports). We extracted relevant information to better understand the burden of HU and to identify knowledge gaps for future study. HU are physiologic events that can complicate existing medical conditions and treatments regardless of duration. Relatively short episodes can have devastating consequences in patients who have pre-existing conditions. HU appear to impact physical and psychological health, diminish QoL, increase healthcare resource use, and increase costs. A better understanding of HU burden is needed.

Ultrasound-guided phrenic nerve block for intraoperative persistent hiccups: a case report.

BACKGROUND: Continuous hiccups during surgery not only affect the surgical procedure, they can also cause adverse effects for the patient. Apart from active investigation of the cause of the hiccups, their timely termination is also necessary. CASE PRESENTATION: We reported a case of a 70-year-old woman with continuous intraoperative hiccups that appeared during vaginal hysterectomy under low continuous epidural anesthesia. After the ineffectiveness CO2 repeated inhalation and intravenous administration of chlorpromazine and methoxychlorpromide, we performed unilateral phrenic nerve block under ultrasound guidance. Hiccups were terminated without any related complications. CONCLUSIONS: During intraoperative continuous hiccups, ultrasound guided phrenic nerve block may be a suitable treatment option when physical methods and drug therapy are not effective. However, given the absence of a vital risk related to hiccups, this block should imply the complete absence of any respiratory contraindication and a prolonged postoperative respiratory monitoring.

Vagal nerve stimulation for intractable hiccups is not a panacea: a case report and review of the literature.

INTRODUCTION: Hiccups are common and typically resolve spontaneously. However, in rare cases, they can continue for days, weeks or even years, causing significant morbidity and discomfort in patients. In the setting of intractable hiccups, vagal nerve stimulation has been reported in two cases. OBJECTIVES: This is a case report and review of the literature regarding the use of vagal nerve stimulators for intractable hiccups. Specifically, this report highlights a case where this therapy was not effective, as two prior case reports have reported positive results. CASE REPORT: A 52-year-old man presented with multiple years of intractable hiccups. A workup revealed no identifiable aetiology, and he had failed multiple medical therapies. A phrenic nerve block was attempted, which was not beneficial. Vagal maneuvers, specifically the induction of emesis, did consistently provide transient relief of his symptoms, and, therefore, the decision was made to proceed with a trial of vagal nerve stimulation after review of the literature supported the therapy. Despite 8 months with multiple stimulation parameters, the patient did not have any significant benefit from vagal nerve stimulation. CONCLUSIONS: Intractable idiopathic hiccups continue to present a significant challenge for physicians and patients. While vagal nerve stimulation is a potentially beneficial therapy, it is not effective in all patients with central idiopathic intractable hiccups.

[Therapeutic effect of cervical Jiaji electroacupuncture on postoperative intractable hiccup of liver neoplasms].

Objective: To evaluate the therapeutic effect of cervical Jiaji electroacupuncture on postoperative intractable hiccup of liver neoplasms. Methods: A total of 39 patients with postoperative intractable hiccup of liver neoplasms in The First Affiliated Hospital of Heilongjiang University of Chinese Medicine from May 2013 to May 2017 were collected and divided into 2 groups randomly. The electroacupuncture group included 20 cases, the control group included 19 cases. Patients in the electroacupuncture group were treated by cervical Jiaji electroacupuncture (located in C3-5, sympathetic ganglion), while the control group were treated by metoclopramide combined with chlorpromazine for three days. The therapeutic effects of two groups were compared and the onset time were recorded. Results: Total effective rates of electroacupuncture group and control group were 95.0% and 47.4%, respectively. The onset time in electroacupuncture group and control group were (14.8±3.3) h and (30.5±3.1) h, respectively (P<0.01). Ten cases who resisted the control treatment were then treated by electroacupuncture for 3 days, 6 cases were recovered, 3 cases became better, while 1 case demonstrated no response. No serious adverse reactions were appeared in each group. Conclusion: Cervical Jiaji electroacupuncture is an effective and safe treatment for postoperative intractable hiccup of liver neoplasms, and it can be used as a remedy for intractable hiccup patients who don't respond to drug treatment.

[Singultus - Diagnostic Workup and Therapy]. / Singultus ­ Diagnostik und Therapie.

A hiccup is a reflex movement with diffusely distributed afferents and efferents in the thorax; its functional relevance is controversial. In its physiological form, it is mostly a minor complaint that stops spontaneously and rarely leads to medical consultation. However, prolonged agonizing hiccups represent serious deterioration of quality of life. Chronic hiccups by definition last for more than 48 h, with gastroesophageal reflux being the frequent underlying disease. Various other causes affect multiple organ systems, some with serious underlying diseases. A hiccup may be the only symptom at the first manifestation of some neurological disorders. In neuroimaging a lesion of the medulla oblongata is often seen. A NMO and an ischemic stroke with Wallenberg syndrome are 2 frequently underlying neurological diseases, but other inflammatory and vascular diseases and tumors of the central nervous system may be present. No optimal evidencebased recommendations for diagnosis and management of chronic hiccups are available. The search for the underlying disease often requires an interdisciplinary approach by internists, neurologists, and otolaryngologists. Symptomatic treatment may be necessary even before diagnosis. Persistent hiccups, a common problem in oncological palliative care, are often challenging. Proton pump inhibitor or prokinetics are used for treating underlying gastroesophageal reflux and baclofen with or without gabapentin in other cases. Anticonvulsants, antipsychotics, antidepressants, and calcium channel blockers represent other alternative treatment possibilities. In therapy-refractory cases, invasive procedures such as the selective phrenic nerve block are available. More studies are needed to help deal with the diagnostic and therapeutic challenge that hiccups present for neurologists.

Management of belching, hiccups, and aerophagia.

Although belching and hiccups are regarded as normal behaviors, they can occur at high frequency or become persistent, becoming bothersome and requiring medical care. Patients with excessive belching frequently have supragastric belches. Excessive belching should be treated as a behavioral disorder. Persistent hiccups, however, can be the first presentation of a serious disorder that requires extensive diagnostic testing. When no cause is found, only the symptoms can be treated. Aerophagia is an episodic or chronic disorder in which patients (children and adults) swallow large quantities of air, which accumulate in the gastrointestinal tract to cause abdominal distention and bloating. These patients should not undergo explorative laparotomy because they do not have ileus. New treatment approaches are needed for patients with aerophagia.

The wonders of the Wanderer.

Vagus is Latin for wandering, and the vagus nerve fully deserves this name due to its extensive distribution through the body. Indeed, one of the lines of the song that accompanied the 2012 G. L. Brown Prize Lecture exaggerates this diversity, 'My function's almost anythin', and vagus is my name'. Alteration of vagal activity was first investigated in the 1880s as a treatment for epilepsy, and vagus nerve stimulation is now an approved treatment for refractory epilepsy and depression in the USA, despite an incomplete understanding of the mechanisms involved. Vagus nerve stimulation could be beneficial in many other conditions, including heart failure, tinnitus, chronic hiccups, Alzheimer's disease and inflammatory diseases. Inhibition of vagal activity could also be beneficial in some conditions, e.g. reducing activation of vagal respiratory afferents to treat chronic cough. This review discusses evidence underlying some current and potential therapeutic applications of vagal modulation, illustrating the wonders of the Wanderer.

Interventions for treating persistent and intractable hiccups in adults.

BACKGROUND: Persistent and intractable hiccups (typically defined as lasting for more than 48 hours and one month respectively) can be of serious detriment to a patient's quality of life, although they are relatively uncommon. A wide range of pharmacological and non-pharmacological interventions have been used for the treatment of persistent and intractable hiccups. However, there is little evidence as to which interventions are effective or harmful. OBJECTIVES: The objective of this review was to evaluate the effectiveness of pharmacological and non-pharmacological interventions used in the treatment of persistent and intractable hiccups of any aetiology in adults. SEARCH METHODS: Studies were identified from the following databases: CENTRAL, CDSR, DARE, MEDLINE, EMBASE, CINAHL, PsychINFO and SIGLE (last search March 2012). The search strategy for all the databases searched was based on the MEDLINE search strategy presented in Appendix 1. No additional handsearching of journals was undertaken. Investigators who are known to be carrying out research in this area were contacted for unpublished data or knowledge of the grey literature. SELECTION CRITERIA: Studies eligible for inclusion in this review were randomised controlled trials (RCTs) or controlled clinical trials (CCTs). INCLUSION CRITERIA: adults (over 18 years old) diagnosed with persistent or intractable hiccups (hiccups lasting more than 48 hours), treated with any pharmacological or non-pharmacological intervention. EXCLUSION CRITERIA: less than ten participants; no assessment of change in hiccup frequency or intensity in outcome measures. DATA COLLECTION AND ANALYSIS: Two independent review authors assessed each abstract and title for relevance. Disagreement on eligibility was resolved by discussion. Where no abstract was available the full paper was obtained and assessed. We obtained full copies of the studies which met the inclusion criteria for further assessment. Two review authors independently collected data from each appropriate study and entered them into the software Review Manager 5. Two independent review authors assessed the risk of bias using the RevMan 5 'Risk of bias' table following guidance from the Cochrane Handbook of Systematic Reviews of Interventions (Higgins 2009). MAIN RESULTS: A total of four studies (305 participants) met the inclusion criteria. All of these studies sought to determine the effectiveness of different acupuncture techniques in the treatment of persistent and intractable hiccups. All four studies had a high risk of bias, did not compare the intervention with placebo, and failed to report side effects or adverse events for either the treatment or control groups. Due to methodological differences we were unable to perform a meta-analysis of the results. No studies investigating pharmacological interventions for persistent and intractable hiccups met the inclusion criteria. AUTHORS' CONCLUSIONS: There is insufficient evidence to guide the treatment of persistent or intractable hiccups with either pharmacological or non-pharmacological interventions.The paucity of high quality studies indicate a need for randomised placebo-controlled trials of both pharmacological and non-pharmacological treatments. As the symptom is relatively rare, trials would need to be multi-centred and possibly multi-national.

Use of paced respiration to alleviate intractable hiccups (Singultus): a case report.

Heart rate variability (HRV) biofeedback is an emerging treatment for many health conditions involving dysregulation of the autonomic nervous system including hypertension, gastric pain, anxiety, and depression. Hiccups are frequently considered an annoyance. However, when intractable (lasting over 1 month), they can become debilitating, with some patients resorting to invasive treatments that often involve the phrenic nerve. Theoretically, HRV biofeedback should also provide a means to stimulate the phrenic nerve and could be an alternative option. We report the successful treatment of a 5 year-long case of intractable hiccups with one session of HRV biofeedback training. These results suggest that biofeedback may be a useful, non-invasive means of relieving intractable hiccups. No clear causality can be inferred from a single case, and further study is needed to determine if this finding has wider applicability.

Acupuncture in the treatment of post-stroke hiccup: A systematic Review and meta-analysis.

Aim: Central hiccups following a stroke are a frequent complication, exerting adverse effects on both the stroke condition and the patient's daily life. Existing treatments exhibit limited efficacy and pronounced side effects. Acupuncture has been explored as a supplementary intervention in clinical practice. This study aims to investigate the clinical effectiveness of acupuncture for post-stroke hiccups.Methods: To identify published clinical randomized controlled trials addressing post-stroke hiccups treatment, comprehensive searches were conducted across PubMed, the Cochrane Library, EMBASE, Web of Science, Chinese Biological Medical (CBM), Wanfang Database, and China Science and Technology Journal (VIP). In addition, we scrutinized ClinicalTrials.gov and the Chinese Clinical Trial Registry. Employing Cochrane Handbook 5.1.0 and Review Manager 5.4 software, three authors independently reviewed literature, extracted data, and evaluated study quality. Data analysis was performed using Stata 16.0 and Review Manager 5.4.Results: A total of 18 trials were encompassed in the analysis. In comparison to standard treatment, acupuncture exhibited a significant enhancement in treatment effectiveness (RR: 1.27, 95% CI: 1.21-1.33; P < 0.00001). Notably, Hiccup Symptom Score displayed a considerable decrease (WMD: -1.28, 95% CI: -1.64 to -0.93; P < 0.00001), concurrent with a noteworthy improvement in the quality of life (WMD: 8.470, 95% CI: 7.323-9.617; P < 0.00001). Additionally, the incidence of adverse reactions decreased (RR: 0.45, 95% CI: 0.16-1.25; P = 0.13), and there was a significant reduction in SAS (WMD: -7.23, 95% CI: -8.47 - -5.99; P < 0.00001).Conclusions: Our investigation suggests that acupuncture could prove effective in post-stroke hiccup treatment. Nonetheless, due to concerns about the quality and size of the included studies, conducting higher-quality randomized controlled trials to validate their efficacy is imperative.

Phrenic nerve block combined with stellate ganglion block for postoperative intractable hiccups: a case report.

Postoperative intractable hiccups slow patient recovery and generate multiple adverse effects, highlighting the importance of investigating the pathogenesis and terminating the hiccups in a timely manner. At present, medical and physical therapies account for the main treatments. We encountered a case in which postoperative intractable hiccups after biliary T-tube drainage removal ceased with the application of an ultrasound-guided block of the unilateral phrenic nerve and stellate ganglion. No complications developed, and the therapeutic effect was remarkable. To our knowledge, this approach has not been reported to date. Simultaneously blocking the phrenic nerve and stellate ganglion may be a treatment option for intractable hiccups.

Healthcare Providers' Experiences with Hiccups in Patients with Cancer: Report of a United States National Survey.

Hiccups occur in 15-40% of cancer patients, but previous research has not sought the perspectives of cancer healthcare providers. The objective of this research is to report on United States cancer healthcare providers' awareness of their patients' hiccups and these healthcare providers' perceived need for further palliation options. A survey was developed and then distributed throughout the United States via email to cancer healthcare providers; results are reported descriptively. Six hundred eighty-four cancer healthcare providers completed 2 eligibility screening questions which required them to have cared for an adequate number of patients (> 10 in the past 6 months) with "clinically significant" hiccups (defined as hiccups that persisted for >48 hours or occurred from cancer or from cancer care). Of 113 eligible healthcare providers, 90 completed the survey. Healthcare providers described hiccups as associated with stress/anxiety, fatigue, sleep problems, and decreased work/school productivity. In 49% of patients, healthcare providers initially prescribed medications (commonly chlorpromazine or baclofen); 18% expressed dissatisfaction with current palliation. Proffered comments included, "When current therapies do not work, it can be very demoralizing to our patients; " and "…my biggest complaint is that current treatments also come with their own side effects which can be quite severe." Discordance appears to exist between the percentage of cancer patients with hiccups and the percentage of cancer healthcare providers with awareness of their patients' hiccups. Nonetheless, healthcare providers described notable hiccup-associated symptoms in their patients and a need for more palliative options.

Fatal posterior circulation stroke with persistent hiccups, sinus arrest and post-hiccup syncope: A case report.

RATIONALE: Diagnosis of posterior circulation stoke is difficult, and magnetic resonance imaging especially diffusion-weighted imaging is superior to computed tomography. Persistent hiccups, sinus arrest, and post-hiccup syncope are extremely rare symptoms of posterior circulation stroke. However, there is no effective treatment for persistent hiccup. PATIENT CONCERN AND DIAGNOSIS: We describe a case of a 58-year-old hypertensive woman diagnosed with acute posterior circulation stroke who presented with persistent hiccups, sinus arrest, and post-hiccup syncope. Diffusion-weighted imaging revealed a high-intensity signal involving the left middle cerebellar peduncle and several spotted areas in the right occipital lobe. INTERVENTIONS: Permanent pacemaker was implanted and metoclopramide was used to treat persistent hiccups. OUTCOME: The patient developed aspiration pneumonia and morbid dysphoria, and eventually died. LESSONS: Posterior circulation stroke can cause cardiovascular and respiratory dysfunction. Consequently, physicians should pay more attention to posterior circulation lesions in patients with arrhythmia and syncope. An effective method to treat persistent hiccups is urgently needed.

Successful termination of persistent hiccups via combined ultrasound and nerve stimulator-guided singular phrenic nerve block: a case report and literature review.

Persistent hiccups that occur after abdominal surgery seriously affect postoperative rehabilitation. Phrenic nerve block therapy has been recommended after failure of medication or physical maneuvers. However, the phrenic nerve is often difficult to accurately identify because of its small diameter and anatomic variations. We combined ultrasound with the use of a nerve stimulator to quickly and accurately identify and block the phrenic nerve in a patient with postoperative persistent hiccups. The ongoing hiccups were immediately terminated with no adverse effects. The patient reported no recurrence during the 2-week follow-up period. We conclude that the combined use of real-time ultrasound guidance and a nerve stimulator for singular phrenic nerve block might be an effective intervention for terminating postoperative persistent hiccups, although further studies are needed to evaluate the safety and efficacy of this technique. The findings in this case suggest a potential clinical application for this technique in managing persistent hiccups, thereby contributing to improved patient care and outcomes.

Ultrasound-guided bilateral pulsed radiofrequency of the phrenic nerve for prolonged hiccups: a case report.

Singultus is the sudden onset of erratic diaphragmatic and intercostal muscle contraction immediately followed by laryngeal closure. Pathophysiology involves afferent, central and efferent components. Bilateral phrenic nerve block was performed to a 46-year-old woman with a brain tumor with persistent hiccups, with initially positive response but later symptom recurrence. Bilateral pulsed radiofrequency of the phrenic nerve was performed guided by ultrasonography (US). In the follow-up, absence of hiccups was confirmed. The patient was discharged 24 h later. Persistent or untreatable singultus is an infrequent condition that should not be dismissed. This approach is a safe, accurate and effective therapeutic approach for patient's refractory to conservative treatment. Further studies are needed to establish safety and effectiveness of the treatment.
