Abstract
BACKGROUND Gastric electrical simulation has been shown to relieve nausea and vomiting in medically refractory patients. Efficacy of gastric electrical stimulation has been reported mostly in short-term studies, but none has evaluated its efficacy beyond 10 years after implantation. METHODS Patients implanted at our center for medically refractory severe and chronic nausea and/or vomiting were evaluated before and over 10 years after implantation using symptomatic scale and quality of life (GIQLI) score. Improvement was defined as a reduction of more than 50% in vomiting frequency. KEY RESULTS A total of 50 patients were implanted from January 1998 to December 2009. Among them, 7 were explanted due to a lack of efficacy and/or side effects, 2 died, and 4 were lost to follow-up. Mean follow-up was 10.5 ± 3.7 years. In intention-to-treat analysis, 27/50 (54%) patients reported an improvement. Beyond 10 years, an improvement in early satiety (3.05 vs 1.76, <0.001), bloating (2.51 vs 1.70, P = .012), nausea (2.46 vs 1.35, P = .001), and vomiting (3.35 vs 1.49 P < .001) scores were observed. Quality of life improved over 10 years (GIQLI score: 69.7 vs. 86.4, P = .005) and body mass index (BMI: 23.4 vs. 26.2 kg/m2 ; P = .048). CONCLUSIONS AND INFERENCES Gastric electrical simulation is effective in the long-term in patients with medically refractory nausea and vomiting, with an efficacy of 54% at 10 years on an intention-to-treat analysis. Other long-term observational studies are warranted to confirm these results.

Abstract
BACKGROUND Patient selection for the diverse surgical procedures for gastroparesis remains poorly defined. Our aim was to evaluate how patient factors have determined our surgical approach to gastroparesis. METHODS 95 patients undergoing 105 surgical procedures for gastroparesis were reviewed. Patient factors were compared across six surgical procedures: gastric neurostimulator, pyloroplasty, neurostimulator plus pyloroplasty, sleeve gastrectomy, gastric bypass and gastrectomy. Global symptom severity was determined preoperatively and at last follow up. RESULTS There were significant differences in etiology, BMI and gastroesophageal reflux across the various operations. Patients undergoing pyloroplasty and gastrectomy; were more likely to have a postsurgical etiology. (p < .05) Patients undergoing sleeve gastrectomy and gastric bypass were more likely to have BMI >35. (p <.05) Those undergoing sleeve gastrectomy were less likely to have gastroesophageal reflux preoperatively. (p <.05) There was no difference in preoperative clinical stage across the procedures. CONCLUSION Patient factors influence choice of procedure in the surgical treatment of gastroparesis. Etiology of gastroparesis, BMI >35 and gastroesophageal reflux are important determinants.

Safety and Feasibility of Per-Oral Pyloromyotomy as Augmentative Therapy after Prior Gastric Electrical Stimulation for Gastroparesis. J Am Coll Surg 2019; 229:589-595. [PMID: 31610231 DOI: 10.1016/j.jamcollsurg.2019.09.014] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2019] [Revised: 09/12/2019] [Accepted: 09/12/2019] [Indexed: 12/29/2022]
Abstract
BACKGROUND For medically refractory diabetic or idiopathic gastroparesis, gastric electrical stimulation (GES) is an excellent option for symptom control; however, a small subset of patients may develop recurrent or persistent symptoms. Per-oral pyloromyotomy (POP, also described by some authors as gastric per-oral endoscopic myotomy or G-POEM) is an emerging therapy for medically refractory gastroparesis. This study investigated the safety and feasibility of POP after previous GES for recurrent or persistent gastroparesis. STUDY DESIGN We retrospectively identified all patients undergoing POP between January 2016 and December 2017, with GES in situ. Patient characteristics, gastroparesis etiology, and procedural data were collected. Symptoms were assessed with the Gastroparesis Cardinal Symptom Index (GCSI) both before and 30 to 90 days after POP. Standard pre- and post-procedure 4-hour gastric emptying tests were obtained when available. RESULTS There were 22 patients who met inclusion criteria (81.8% female, mean age 42.3 ± 12.4 years). Causes of gastroparesis were diabetes in 38.1%, and idiopathic in 61.9%. The average time since GES insertion was 3.45 years. Mean preoperative 4-hour gastric retention was 50.1%. Most POP procedures were performed in the operating room (90.9%), with mean operative time of 40 minutes and a 1.4-day length of stay. There were 4 readmissions within 30 days, but no POP-related complications. Overall, GCSI improved by an absolute reduction of 1.63 points (p = 0.002), with significant improvements in all sub-scores. Of 11 patients with post-procedural motility or emptying studies available, 7 were normal. CONCLUSIONS Per-oral pyloromyotomy appears to be safe and feasible for patients with recurrent gastroparesis symptoms after GES. Both symptoms and motility significantly improved in the short-term. These data replicate similar data suggesting laparoscopic pyloroplasty as an effective augmentative therapy after GES, but may provide a less invasive option for patients.

Abstract
OBJECTIVE For patients with gastroparesis, temporary pyloric disruption has been shown to improve symptoms and gastric emptying. Per-oral pyloromyotomy (POP) is an innovative endoscopic procedure to divide the pylorus from within a submucosal tunnel, as a corollary to surgical pyloromyotomy. Here we evaluate subjective and objective outcomes 12-weeks after POP at a high volume center. METHODS The first 100 consecutive patients undergoing POP were included, with procedure dates between January 2016 and October 2017. Patients were evaluated using the Gastroparesis Cardinal Symptom Index (GCSI), and 4-hour solid-phase scintigraphic gastric emptying studies (GES) prior to procedure and at 90 days post-POP RESULTS:: The study cohort was 85% female with a mean age of 45.0 ± 14.6 years. Gastroparesis etiologies were divided among idiopathic (56%), diabetic (21%), postsurgical (19%), and other in 4%. There were 67% of the patients who had previous endoscopic or surgical interventions for gastroparesis. Most POP procedures were performed in the operating room (97%) and were completed in an average of 33 minutes. Ten patients incurred complications (10%), which included 1 diagnostic laparoscopy and 2 cases of gastrointestinal bleeding. Overall GCSI improved from a preoperative mean of 3.82 ± 0.86 to 2.54 ± 1.2 (P < 0.001). The improvement in each GCSI subscore was also highly statistically significant. Among the patients with postoperative GES available, 78% had objectively better 4-hour emptying with a mean improvement in retention by 23.6% (P < 0.001). This included 57% of patients with normal gastric emptying post-POP. CONCLUSION For patients with medically refractory gastroparesis, POP results in both subjective and objective improvement in the majority of patients. Prior intervention does not obviate POP as a therapeutic option. POP should be included along the treatment algorithm for patients with gastroparesis as an organ-sparing procedure.

Abstract
OBJECTIVES Idiopathic gastroparesis is a gastric motility disorder characterized by chronic upper gastrointestinal symptoms and delayed gastric emptying without an identifiable underlying condition. This review summarizes recent understanding of the pathophysiology and treatment of idiopathic gastroparesis. MATERIALS AND METHODS Structured literature search in the PubMed, Embase and ClinicalTrials.gov databases. RESULTS Idiopathic gastroparesis involves several alterations in gastric motility and sensation, including delayed gastric emptying, altered myoelectrical activity, impaired fundic accommodation, visceral hypersensitivity and disturbances in antropyloroduodenal motility and coordination. Multiple cellular changes have been identified, including depletion of interstitial cells of Cajal (ICC) and enteric nerves, as well as stromal fibrosis. The underlying cause of these changes is not fully understood but may be an immune imbalance, including loss of anti-inflammatory heme-oxygenase-1 positive (HO-1) macrophages. There is currently no causal therapy for idiopathic gastroparesis. The treatment ladder consists of dietary measures, prokinetic and antiemetic medications, and varying surgical or endoscopic interventions, including promising pyloric therapies. There are ongoing trials with several novel medications, raising hopes for future treatment. CONCLUSIONS Patients with idiopathic gastroparesis present several pathophysiological alterations in the stomach, where depletion of ICC is of special importance. Treatment is currently focused on alleviating symptoms through dietary adjustments, medication or surgical or endoscopic interventions.

Abstract
Gastroparesis is a debilitating chronic condition of indeterminate cause. Although conservative management is the mainstay of treatment, a significant percentage of patients will need interventions. Interventions range from supportive measures, such as feeding tubes, to more radical surgeries, including endoscopic pyloromyotomy (per oral pyloromyotomy), laparoscopic pyloroplasty, laparoscopic gastric stimulator placement, and even subtotal or total gastrectomy. The authors present some current treatment algorithms focused on the treatment side of the spectrum along with outcomes data to support the various approaches.

Abstract
Background/Aims Recurrent nausea and/or vomiting are common complications of diabetes mellitus. The conditions severely impact the quality of life of patients and often cause repeated admissions to hospital incurring significant healthcare costs. If standard treatment fails, gastric electrical stimulation (GES) may be offered in selected cases, as a minimally invasive, but expensive, therapeutic option. Our aims are to evaluate the clinical effect and the cost-utility of GES as a treatment for severe diabetic recurrent nausea and/or vomiting. Methods Among 33 diabetes patients implanted with GES because of recurrent nausea and/or vomiting, 30 were available for evaluation. The effect of treatment was assessed prospectively using symptom-diaries and the SF-36 questionnaires at baseline, after 6 and 12 months, and thereafter yearly. The number of days in hospital due to symptoms related to gastrointestinal dysfunction was calculated using hospital records 12 months prior to and 12 months after implantation. Results The surgical procedures were performed without mortality or major complications. Six months after surgery 78% of the respondents had at least 50% reduction in time with nausea and 48% had at least 50% reduction in days with vomiting. Symptom relief persisted at follow-up after at least 4 years. Quality adjusted life years improved after GES, which was cost-effective after 24 months. Conclusions GES reduces symptoms and improves quality of life in diabetes patients with recurrent nausea and/or vomiting. The procedure is supposed as cost-effective over a 2-year time horizon.

Abstract
BACKGROUND The aims of this study were to describe the histology in gastroparesis, specifically to relate histopathology to etiology of gastroparesis (idiopathic and diabetic gastroparesis), gastric emptying, and clinical response to gastric electric stimulation. METHODS Full thickness gastric body sections obtained during insertion of gastric stimulator in gastroparetics were stained with Hematoxylin & Eosin, Masson Trichrome and immunohistochemical stains for Neuron-Specific Enolase and c-Kit. KEY RESULTS In all, 145 gastroparetics (71 diabetics, 71 idiopathic, 2 post-surgical, and 1 chronic intestinal pseudo-obstruction) had full thickness gastric body biopsies. A lymphocytic infiltrate was seen in the intermyenteric plexus in 22 diabetic and 23 idiopathic gastroparesis patients. Fibrosis was present in the inner circular layer in 13 diabetic and 15 idiopathics and in the outer longitudinal layer in 46 diabetic and 51 idiopathics. Diabetic gastroparesis had less ganglion cells (3.27±1.82 vs 4.81±2.81/hpf; P<.01) and less ganglia (0.90±0.44 vs 1.10±0.50/hpf; P=.01) than idiopathic gastroparesis. Interstitial cells of Cajal (ICC) count was slightly lower in the inner circular layer in diabetic than idiopathics (2.77±1.47 vs 3.18±1.34/hpf; P=.08). Delayed gastric emptying was associated with reduced ICCs in the myenteric plexus. Global therapeutic response to gastric electric stimulation was inversely related to ganglia/hpf (R=-.22; P=.008). In diabetics, improvements in nausea, vomiting, and abdominal pain were inversely related to fibrosis. CONCLUSION AND INFERENCES Histologic assessment of full thickness gastric biopsy specimens allows correlation of histopathology to the gastroparesis disease process, its etiology, gastric emptying, and response to gastric electric stimulation treatment.

Abstract
INTRODUCTION Gastroparesis is a debilitating disease characterized by delayed gastric emptying in the absence of mechanical obstruction. A new intramural technique, per oral endoscopic pyloromyotomy (POP), has been proposed as an alternative to surgical pyloroplasty for the management of medical refractory gastroparesis. Herein, we detail the short-term results of POP at our institution. METHODS POP was first performed at our institution in January 2016. All patients undergoing POP for management of gastroparesis from January 2016 through January 2017 were prospectively followed. All patients underwent a 4-h, non-extrapolated gastric emptying scintigraphy study and were asked to rate their symptoms using the Gastroparesis Cardinal Symptom Index (GCSI) at their pre-procedure visit and at 3 months post-procedure. RESULTS A total of 47 patients underwent POP during the defined study period. Twenty-seven (57.4%) patients had idiopathic gastroparesis, 12 (25.6%) had diabetic gastroparesis, and eight (17.0%) had post-surgical gastroparesis. Forty-one (87.2%) patients had at least one previous intervention (i.e., enteral feeding tube, gastric pacer, botox injection) for their gastroparesis symptoms. All patients had evidence of gastroparesis on pre-procedure gastric emptying studies. The average length of hospital stay was 1 day. One patient died within 30-days of their index procedure which was unrelated to the procedure itself. The average pre-procedure percentage of retained food at 4 h was 37% compared to an average post-procedure percentage of 20% (p < 0.03). The average pre-procedure GCSI score was 4.6 compared to an average post-procedure GCSI of 3.3 (p < 0.001). CONCLUSIONS POP is a safe and feasible endoscopic intervention for medical refractory gastroparesis. Additional follow-up is required to determine the long-term success of this approach in alleviating gastroparesis symptoms.

Abstract
OBJECTIVE Improvement in regional blood flow has been shown to ameliorate diabetic gastroparesis. We compared the gastric blood supply in patients with diabetes with gastroparesis with that in healthy subjects, by using contrast-enhanced ultrasound (CEUS). METHODS 30 healthy subjects and 40 patients with diabetic gastroparesis were enrolled. The CEUS parameters of greater curvatures of the antrum (GCOA) and lesser curvatures of the antrum (LCOA), including peak intensity (PI) and the area under the curve (AUC), were compared between the two groups. RESULTS Intraclass correlation coefficient (ICC) for PI in healthy subjects measured on CEUS were 0.831-0.857 and 0.803-0.823, respectively. Intra-ICC and inter-ICC values for AUC were 0.805-0.823 and 0.813-0.815, respectively. In both groups, no significant difference was observed in PI and AUC values of GCOA and LCOA (p > 0.05). The PI and AUC of GCOA and LCOA in the diabetes group were less than those in the normal group (p < 0.05). CONCLUSION CEUS can assess stomach wall vascularity with a high reproducibility. Microcirculation in the antrum of patients with diabetic gastroparesis is poorer than that of normal group, which is consistent with the mechanisms of diabetic neuropathy. CEUS can be used for evaluation of microvascular perfusion in patients with stomach wall disease. Advances in knowledge: This was the first study to use CEUS for assessment of blood supply of the gastric wall and to compare microvascular perfusion between healthy individuals and patients with diabetes with gastroparesis.

OPINION STATEMENT Gastroparesis is a heterogeneous clinical syndrome. Some patients have debilitating vomiting, weight loss, and dehydration, while others have effortless regurgitation of undigested foods or postprandial distress suggestive of functional dyspepsia. Gastric electrical stimulation (GES) has been proposed as an effective treatment option for patients with gastroparesis refractory to medical therapy. Evidence suggests that the clinically available device, a low-energy high-frequency GES, activates the vagal afferent pathways to influence the central control mechanisms for nausea and vomiting. Myoelectrical effects of the stomach are also involved. The results of randomized controlled trials (RCTs) for adults with diabetic and idiopathic gastroparesis are conflicting. There are no RCTs in adults with chronic unexplained nausea and vomiting (CUNV) with normal gastric emptying or in children with gastroparesis. However, there is increasing evidence from large unblinded studies showing the long-term efficacy in selected adults with gastroparesis. Selection criteria should be based on three categories: (a) underlying etiology, (b) clinical presentation and predominant symptoms, and (c) potential risk for complication. Significant abdominal pain, daily opiate use, and idiopathic gastroparesis are identified as negative predictors of success. Temporary GES has been utilized to identify patients who may benefit from surgical GES, but this strategy has yet to be proven in controlled studies. Objectives for this review are to highlight the mechanisms of action for GES, to look at the evidence for clinical efficacy, and to select patients who are likely to benefit.

Abstract
BACKGROUND Controlled trials of gastric electrical stimulation (GES) for gastroparesis reported no significant improvement in symptoms, while open label studies suggested substantial clinical benefits. AIM To determine if GES is effective in reducing symptoms in patients with gastroparesis. METHODS We searched PubMed and Embase for articles published in English (1990-2014) using "gastroparesis" as a search term restricted to "clinical trial". We included studies describing repeated patient-based symptom ratings before and during standardized treatments of at least one week duration. RESULTS Five studies randomly allocated patients to periods with or without GES. Total symptom severity (TSS) scores did not differ between these periods (0.17 [95% confidence interval: -0.06 to 0.4]; P=0.15). However, sixteen open label studies of GES showed a significant TSS decrease (2.68 [2.04-3.32]; Q=39.0; P<0.001). Other treatment modalities similarly improved TSS by 1.97 [1.5-2.44] for medical therapy (MED), by 1.52 [0.9-2.15] for placebo arms (PLA), and by 2.32 [1.56-3.06] for botulinum toxin (BTx). There were significant differences in baseline TSS ratings among these studies (GES: 6.28 [6.28-7.42]; MED: 4.76 [4.09-5.42]; PLA: 4.59 [3.77-5.42]; BTx: 6.02 [5.3-6.74]; Q=35.1; P<0.001). Meta-regression analysis showed these baseline differences to significantly impact TSS ratings during treatment (Q=71.8; P<0.001). CONCLUSION Independent of the treatment modality, baseline symptom severity impacts treatment results in gastroparesis. Considering the skewed population with refractory symptoms, regression to the mean likely contributes to the substantial discrepancies between the reported results of controlled and open label GES studies, raising questions about the use of GES outside of defined clinical trials.

Abstract
BACKGROUND Gastric electric stimulation (GES) is used to treat patients with refractory gastroparesis symptoms. However, the effectiveness of GES in clinical practice and the effect of GES on specific symptoms of gastroparesis are not well delineated. AIMS To determine the effectiveness of GES for treatment for refractory symptoms of gastroparesis, the improvement in specific symptoms of gastroparesis, and clinical factors impacting on outcome. METHODS Enterra GES was used to treat refractory gastroparesis symptoms. Patients filled out a symptom severity questionnaire (PAGI-SYM) prior to insertion. At each follow-up visit, the patient filled out PAGI-SYM and assessed their therapeutic response using the Clinical Patient Grading Assessment Scale (CPGAS). RESULTS One hundred and fifty-one patients (120 females) with refractory gastroparesis (72 diabetic, 73 idiopathic, 6 other) underwent GES. Of the 138 with follow-up (1.4 ± 1.0 years), the average CPGAS was 2.4 ± 0.3 (SEM): 104 patients (75 %) improved (CPGAS > 0) and 34 (25 %) did not (CPGAS ≤ 0). Sixty patients (43 %) were at least moderately improved (CPGAS score ≥4). Clinical improvement was seen in both diabetic and idiopathic patients with the CPGAS in diabetic patients (3.5 ± 0.3) higher in idiopathic patients (1.5 ± 0.5; p < 0.05). Symptoms significantly improving the most included nausea, loss of appetite, and early satiety. Vomiting improved in both diabetic and idiopathic patients although the diabetic subgroup experienced a significantly greater reduction in vomiting than the idiopathic subgroup. CONCLUSIONS In this cohort of patients with refractory gastroparesis, GES improved symptoms in 75 % of patients with 43 % being at least moderately improved. Response in diabetics was better than in nondiabetic patients. Nausea, loss of appetite, and early satiety responded the best.

Abstract
Syringomyelia is a chronic progressive disease of the spinal cord. In symptomatic patients, bilateral sensory motor signs and symptoms prevail, moreover they can develop gastrointestinal disorders, although few studies have succeeded in explaining this correlation so far. We report a case of a 67-year-old woman with a history of pain in the back-lumbar spine and lower limbs, paresthesia and urinary incontinence. MRI revealed syringomyelia, extended from T3 to the medullary cone. Neurological picture was worsened by progressive and increasingly debilitating gastrointestinal symptoms refractory to dietary changes and medical treatment. Blood tests, gastrointestinal investigations and imaging were all normal apart from scintigraphy which confirmed delayed gastric emptying. The neurological symptoms disappeared after removal of an hemangioblastoma of the medullary cone. The persistent gastroparesis was treated by total gastrectomy with complete resolution of the patient's gastrointestinal symptoms. Syringomyelia is a spinal disorder rarely associated with gastrointestinal dysfunction. We present a case of refractory gastroparesis in a female patient with syringomyelia. Surgery may be indicated if dietary changes and medical management fails. We performed a total gastrectomy with improvement in the patient's quality of life.

Abstract
PURPOSE OF REVIEW This review covers the cause, evaluation and treatment options for gastroparesis. Symptoms of delayed gastric emptying are increasingly seen by gastroenterologists and gastrointestinal surgeons. Endoscopy - both laparoscopic and flexible - is increasingly important in treatment algorithms for this problem. RECENT FINDINGS Gastroparesis is increasingly being seen in clinical practice. A progressive algorithm needs to be followed in these challenging cases: starting with medical treatment and diet modification, progressing through endoscopic treatments including new ones such as per-oral pyloromyotomy, and finally laparoscopic treatments including gastrectomy. SUMMARY Endoscopic interventions are effective treatments for certain gastroparesis patients. New procedures offer a minimally invasive alternative to more radical options and should probably be more widely adopted.

Abstract
Gastroparesis in a chronic setting is a disorder that results in diminished quality of life. Laparoscopic gastric electrical stimulator (GES) placement is now being performed in patients with medically refractory gastroparesis. During this procedure, a significant amount of suturing is required to anchor the electrodes to the gastric wall. Robotic surgery may provide surgeons with several technical and ergonomic advantages during this procedure, when compared with a standard laparoscopic approach. The aim of this study is to present a case and review the technique and literature for robotic placement of GES. This report demonstrates the safety and feasibility of robotic GES placement.

Pre-operative opioid analgesia reduces clinical success of laparoscopic gastric electrical stimulation placement in patients with gastroparesis. Surg Endosc 2014; 29:805-9.

Abstract
INTRODUCTION Gastroparesis is a common chronic and costly disorder for which medical therapy is often unsuccessful. Gastric electrical stimulation (GES) has been used to treat refractory cases, however, response is variable and difficult to predict. This study aims to assess whether pre-operative opioid analgesics (OA) use affects clinical success of GES. METHODS Records of 128 patients who underwent laparoscopic GES placement from March 2001 to September 2012 were analyzed retrospectively. Data collected included demographics, surgical outcomes, and clinical parameters. Pre- and post-operative opioid analgesic dosing (No = 0 morphine equivalents (ME)/day, Low = 0-40 ME/day, Mid = 41-80 ME/day, High >80 ME/day), as well as clinical symptom assessment was collected for up to 3 years post-operatively. Clinical success was defined as (1) OA reduction of >50 %, (2) maintenance of weight, or (3) symptom improvement. Descriptive statistics were computed for all factors. A p < 0.05 was considered statistically significant. RESULTS Fifty-three patients were on OA pre-operatively compared to 69 patients who were not. Patients not on OA pre-operatively were less likely than those on OA pre-op group to be on OA post-operatively (p = 0.005); however, there were no differences in weight or symptom improvement. Sub-group analysis of the 53 patients on OA demonstrated significant improvement in clinical symptoms in the low-morphine cohort compared to the mid-morphine cohort (p = 0.02), and OA dosing post-operatively in the low-morphine cohort diminished significantly compared to mid- and high-morphine cohort (p = 0.032). There was no significant difference in weight. CONCLUSION OA dosing pre-operatively significantly affects clinical success of GES placement. Criteria for offering GES implantation may need to take OA dosing into consideration.

Abstract
Refractory diabetic gastroparesis (DGP), a disorder that occurs in both type 1 and type 2 diabetics, is associated with severe symptoms, such as nausea and vomiting, and results in an economic burden on the health care system. In this article, the basic characteristics of refractory DGP are reviewed, followed by a discussion of therapeutic modalities, which encompasses the definitions and clinical manifestations, pathogenesis, diagnosis, and therapeutic efficacy evaluation of refractory DGP. The diagnostic standards assumed in this study are those set forth in the published literature due to the absence of recognized diagnosis criteria that have been assessed by an international organization. The therapeutic modalities for refractory DGP are as follows: drug therapy, nutritional support, gastric electrical stimulation, pyloric botulinum toxin injection, endoscopic or surgical therapy, and traditional Chinese treatment. The therapeutic modalities may be used alone or in combination. The use of traditional Chinese treatments is prevalent in China. The effectiveness of these therapies appears to be supported by preliminary evidence and clinical experience, although the mechanisms that underlie these effects will require further research. The purpose of this article is to explore the potential of combined Western and traditional Chinese medicine treatment methods for improved patient outcomes in refractory DGP.
