OBJECTIVE: To observe the clinical effect of acupuncture for functional delayed gastric emptying after gastric cancer surgery on the basis of routine treatment. METHODS: A total of 80 patients with functional delayed gastric emptying after gastric cancer surgery were randomly divided into an observation group (40 cases, 3 cases dropped off) and a control group (40 cases, 1 case dropped off). The control group was treated with routine treatment, e.g. continuous gastrointestinal decompression. On the basis of the treatment in the control group, the observation group was treated with acupuncture at Zusanli (ST 36), Shangjuxu (ST 37), Xiajuxu (ST 39), Gongsun (SP 4), Sanyinjiao (SP 6), 30 min each time, once a day, 5 days as a course, 1-3 courses were required. The first exhaust time, remove gastric tube time, liquid food intake time and hospital stay were compared in the two groups, and the clinical effect was evaluated. RESULTS: The first exhaust time, remove gastric tube time, liquid food intake time and hospital stay in the observation group were shorter than the control group (P<0.001). CONCLUSION On the basis of routine treatment, acupuncture could accelerate the recovery of patients with functional delayed gastric emptying after gastric cancer surgery.

OBJECTIVE: To observe the effect of electroacupuncture (EA) at "Zusanli" (ST 36) combined with mosapride on gastric emptying rate and gastric motility in the rats with diabetic gastroparesis. METHODS: Using random number table method, 68 male SD rats were divided into a blank group (12 rats) and a model establishment group (56 rats). In the model establishment group, the models of diabetic gastroparesis were established with intraperitoneal injection of streptozotocin combined with high-fat and high-sugar diet. Six weeks later, the successful rat models in the model establishment group were randomized into a model group, an EA group, a mosapride group and a combined treatment group, 12 rats in each one. In the EA group, EA was exerted at "Zusanli" (ST 36) (disperse-dense wave, 2 Hz/15 Hz in frequency, 2 mA in intensity) for 20 min. In the mosapride group, mosapride was intervened with intragastric administration (2 mg/kg). In the combined treatment group, electroacupuncture at "Zusanli" (ST 36) was combined with intragastric administration of mosapride. The intervention was given once daily in each group. There was 1 day at interval after 6-day intervention, consecutively for 5 weeks. At the end of intervention, the random blood glucose, gastric emptying rate and the data of gastric motility (average intra-gastric pressure, amplitude and frequency of gastric motility) were detected. RESULTS: Compared with the blank group, blood glucose was increased in the model group (P<0.001). Blood glucose was reduced in the EA group, the mosapride group and the combined treatment group as compared with the model group separately (P<0.001, P<0.01), whereas, compared with the mosapride group, blood glucose was decreased in the combined treatment group (P<0.05). In comparison with the blank group, the gastric emptying rate, the average intra-gastric pressure and the amplitude of gastric motility were all decreased in the model group (P<0.001) and the frequency of gastric motility was increased (P<0.001). Gastric emptying rate, the average intra-gastric pressure and the amplitude of gastric motility were increased in the EA group, the mosapride group and the combined treatment group (P<0.01, P<0.05, P<0.001) and the frequency of gastric motility was decreased (P<0.001) as compared with the model group respectively. Compared with the EA group, the average intra-gastric pressure and the amplitude of gastric motility were increased in the combined treatment group (P<0.001). In comparison with the mosapride group, the gastric emptying rate, the average intra-gastric pressure, the amplitude and frequency of gastric motility in the combined treatment group, as well as the frequency of gastric motility in the EA group were all increased (P<0.05, P<0.001, P<0.01). CONCLUSION Electroacupuncture at "Zusanli" (ST 36) combined with intragastric administration of mosapride could regulate blood glucose and improve the gastric motility in the rats with diabetic gastroparesis. The effect is better than either simple electroacupuncture or mosapride.

Delayed gastric emptying is a syndrome of gastric motility disorder with slow gastric emptying as the main sign, provided that mechanical factors such as intestinal obstruction and anastomotic stricture are excluded. The incidence of delayed gastric emptying after colon cancer surgery is 1.4%, mainly after transverse colon cancer surgery. Most of the studies on delayed gastric emptying are case reports, lacking systematic studies. The diagnoses and treatments can be draw on the experience of delayed gastric emptying after pancreatic surgery. Our retrospective study indicated that the incidence of delayed gastric emptying after surgery for transverse colon cancer was 4.0%, higher than that for other colon cancer. Patients who underwent gastrocolic ligament lymph node dissection were at higher risk than those who did not (3.6% vs. 0.8%). Gastrocolic ligament lymph node dissection and stress are causative factors for delayed gastric emptying after surgery for transverse colon cancer. We add the gastrografin test upon the diagnostic criteria of the International Study Group for Pancreatic Surgery, which is simple and practical. Nasogastric tube decompression, enteral nutrition combined with parenteral nutrition, glucocorticoids, and prokinetic agents can cure most patients with postoperative delayed gastric emptying. All the patients with postoperative delayed gastric emptying were cured in our studies. Strict indications for gastrocolic ligament lymph node dissection (patients with cT3-4 and cN+) may decrease the occurrence of delayed gastric emptying after surgery for transverse colon cancer.

At present, comprehensive treatment dominated by surgical procedures is an important measure for colon cancer to obtain the chance of cure. Surgical intervention, while removing the tumor, carries the risk of postoperative gastroparesis (PG) . Because of the low incidence rate and insignificant early clinical symptoms, early stage PG is often overlooked clinically. However, PG can increase the risk of malnutrition, delay postoperative antitumor treatment, and increase the risk of tumor recurrence and metastasis. This review focuses on the mechanisms, clinical risk factors, preventive measures, and advances in treatment of PG due to colon cancer. Aim to increase the clinician's adequate attention to PG in colon cancer and from a surgical point to reduce the risk of gastroparesis in colon cancer by optimizing the surgical strategy.

This paper was aimed to study the effects of Qizhiweitong particles (QZWT) on gastric motility in gastroparesis model rats, and to provide a theoretical and experimental basis for its clinical treatment. Rat gastroparesis model was established by bilateral injection of 6-hydroxydopamine into the substantia nigra in male Sprague-Dawley (SD) rats. The model rats received single gastric feeding of 1, 10, 30, 100, 200, 450, or 675 mg/kg QZWT or continuous administration of 675 mg/kg QZWT per day for 7 days. The gastric motility was measured by gastric emptying study and in vivo digital X-ray imaging system. The in vivo and ex vivo gastric longitudinal muscle contraction was recorded by PowerLab biological signal acquisition system. Gastric myoelectric signals were recorded by wireless implantable telemetry system. Protein expression levels of proinflammatory proteases in the myometrium were determined by Western blot. The results showed that the single administration of QZWT dose-dependently inhibited the contractile activity of isolated gastric strips from normal rats. The single administration of QZWT inhibited the in vivo contraction of gastric smooth muscle and gastric myoelectric signal in the control and model rats. The gastric emptying rate, in vivo and ex vivo gastric motility and gastric myoelectric signal in the model rats were significantly decreased compared with those in the control rats; While the continuous administration of QZWT markedly improved all the above indices of gastric motility function. The single administration of QZWT inhibited isolated gastric muscle strip contraction, and neither atropine nor nitric oxide synthase inhibitor pretreatments affected QZWT's inhibitory effects. The continuous administration of QZWT down-regulated the increased protein expression levels of nitric oxide synthase and cyclooxygenase 2 in the model group. These results suggest that, in clinical treatment, the single administration of QZWT may induce an analgesic effect by rapidly inhibiting gastric motility, while this effect is not related to acetylcholine or nitric oxide pathways. Long-term treatment with QZWT may ameliorate gastric motility through enhancing myoelectric activities, gastric smooth muscle contraction and gastric emptying, and this effect may partly be related to its anti-inflammatory effect.

OBJECTIVE: To explore the clinical therapeutic effect of herb-partitioned moxibustion at point in patients of diabetic gastroparesis differentiated as spleen and stomach deficiency and retention of turbid dampness as well as its effect mechanism. METHODS: A total of 134 patients with diabetic gastroparesis were randomized into an observation group and a control group, 67 cases in each one. In the observation group, herb-partitioned moxibustion at point was adopted, 40 min each time, once a day for 5 times a week. In the control group, itopride hydrochloride tablets were prescribed for oral administration, 50 mg each time, three times a day. A total of 6 weeks of treatment was required in the two groups. Before and after treatment, the gastroparesis cardinal symptom index (GCSI) scores, 4-hour gastric emptying rate, TCM symptom score, as well as the levels of plasma motilin and serum gastrin were observed in the patients of the two groups. Additionally, the clinical therapeutic effect was evaluated in the two groups. RESULTS: After treatment, the score of every item of GCSI, TCM symptom scores and the levels of plasma motilin and serum gastrin were all reduced as compared with those before treatment in the patients of the two groups (<0.05), and those in the observation group were lower than the control group (<0.05). Regarding 4-hour gastric emptying rates, which were increased as compared with those before treatment in the two group (<0.05), and the rate in the observation group was higher remarkably than that in the control group (<0.05). The total effective rate was 92.5% (62/67) in the observation group, higher than 74.6% (50/67) in the control group (<0.05). CONCLUSION Herb-partitioned moxibustion at point relieves the clinical symptoms in the patients with diabetic gastroparesis and increases the gastric emptying rate, which is probably related to the regulation of the levels of plasma motilin and serum gastrin.

OBJECTIVE: To establish a modified endoscopic Freka Trelumina placement (mEFTP) for modifying or substituting the traditional endoscopic Freka Trelumina placement (EFTP) and to explore the safety and feasibility of mEFTP in patients requiring enteral nutrition and gastrointestinal decompression in general surgery. METHODS: A retrospective cohort study was conducted to analyze the clinical data of patients undergoing EFTP or mEFTP at General Surgery Department of 920 Hospital of the Joint Logistics Support Force of the Chinese People's Liberation Army from January 2016 to January 2018. INCLUSION CRITERIA: the function of lower digestive tract was normal; patients who could not eat through mouth or nasogastric tube needed to have enteral nutrition and gastrointestinal decompression; the retention time of Freka Trelumina (FT) was not expected to exceed 2 months. EXCLUSION CRITERIA: contraindication for gastroscopy; suspected shock or digestive tract perforation; suspected mental diseases; infectious diseases of digestive tract; thoracoabdominal aortic aneurysm. mEFIP procedure was as follow. FT was inserted into stomach through one side nasal cavity, gastroscope was inserted into stomach cavity, and the front part of FT was clamped with biopsy forceps through biopsy hole. Biopsy forceps and FT were inserted into the pylorus or anastomosis under gastroscope, and they were pushed into the duodenum or output loop. During pushing, the gastroscope did not pass through the duodenum or output loop. The biopsy forceps was released and pushed out, and FT was pushed with biopsy forceps synchronously into the duodenum or output loop more than 5 cm. The foreign body forceps was inserted through the biopsy hole, and the FT tube was held in the stomach and pushed to the duodenum or output loop. The previous steps repeated until the suction cavity reached the pylorus or anastomosis. The gastroscope was exited gently; the guide wire was pulled out slowly. EFTP procedure: foreign body forceps was used to clamp the front part of FT, and gastroscope, foreign body forceps and FT pass the pylorus or anastomosis simultaneously to reach the descendent duodenum or output loop as a whole. The time of catheterization was recorded and position of FT was examined by X-ray within 1 h after catheterization. The success rate of catheterization and morbidity of complications after catheterization were evaluated and compared between the two groups. RESULTS: A total of 141 patients were enrolled, 72 in the mEFTP group and 69 in the EFTP group. In mEFTP group, 45 cases were males and 27 were females with an average age of 55.8(37-76) years; 27 cases had normal upper gastrointestinal anatomy (postoperative gastroplegia syndrome due to colon cancer in 17 cases, due to rectal cancer in 10 cases) and 45 had upper gastrointestinal anatomic changes (gastric cancer with pylorus obstruction in 18 cases and anastomotic block after gastroenterostomy in 27 cases). In the EFTP group, 41 were males and 28 were females with an average age of 55.3(36-79) years; 33 cases had normal upper gastrointestinal anatomy (postoperative gastroplegia syndrome due to colon cancer in 20 cases, due to rectal cancer in 13 cases) and 36 had upper gastrointestinal anatomic changes (gastric cancer with pylorus obstruction in 15 cases and anastomotic block after gastroenterostomy in 21 cases). In patients with normal upper digestive tract anatomy, the average catheterization time of mEFTP was (4.9±1.7) minutes which was shorter than (7.6±1.7) minutes of EFTP(t=6.683, P<0.001). In patients of gastric cancer with pyloric obstruction, the average catheterization time of mEFTP was (6.6±1.6) minutes which was shorter than (10.5±2.6) minutes of EFTP (t=4.724, P<0.001). In patients with anastomotic block after gastroenterostomy, the average catheterization time of mEFTP was (11.3±2.5) minutes which was shorter than (15.1±3.5) minutes of EFTP (t=4.513, P<0.001). In patients with normal upper gastrointestinal anatomy, there were no significant differences in the success rate of catheterization and the morbidity of catheterization complication between mEFTP and EFTP (all P>0.05). In patients with upper gastrointestinal anatomic changes, the success rate of catheterization in mEFTP was even higher than that in EFTP, but the difference was not significant [97.8%(41/45) vs. 86.1%(31/36), χ²=2.880, P=0.089]; while the morbidity of catheterization complication in mEFTP was lower than that in EFTP [0 vs. 8.3%(3/36), χ²=3.894, P=0.048]. CONCLUSIONS Whether the upper gastrointestinal anatomy is normal or not, mEFTP presents shorter catheterization time, higher success catheterization rate than EFTP, and is safety. mEFTP can be widely applied to clinical practice for patients requiring enteral nutrition and gastrointestinal decompression.

Pylorospasm is a cause of delayed gastric emptying in young infants. As in patients with hypertrophic pyloric stenosis, most pylorospasm patients present with projectile vomiting. However, unlike that in case of hypertrophic pyloric stenosis, no persistent pyloric stenotic lesions are present. As such, follow-up using serial gastrointestinal fluoroscopy or ultrasonography can be helpful in diagnosing patients with clinical signs of gastroparesis. Most cases can be treated conservatively, but some patients require pharmacologic treatment. Antispasmodics have been proposed as a treatment for pylorospasm, but their use in neonates and infants has rarely been reported. Herein, we present a case of pylorospasm diagnosed in the neonatal period and successfully treated with intravenous atropine.

The prevalence of small bowel cancer is relatively low. The abdominal pain that patients with small bowel cancer present as a symptom is non-specific and often interpreted as a normal finding on radiographic studies. To prevent delayed diagnosis of small bowel cancer, practitioners must maintain a certain level of suspicion. We report a case of delayed diagnosis of jejunal cancer as it was misdiagnosed as gastroparesis. A 69-year-old woman complained of recurrent nausea and vomiting. At the beginning of her hospitalization, we could not diagnose mechanical obstruction through esophagogastroduodenoscopy and abdominal computed tomography. A gastric emptying study revealed delayed gastric emptying. Although the patients received treatments, including administration of prokinetics and botulinum toxin injection, for gastroparesis, her symptoms aggravated. Subsequently, plain radiography of the abdomen revealed a double-bubble sign. Abdominal computed tomography was performed under the suspicion of small bowel obstruction; however, the diagnosis was not clear. Consequently, exploratory laparoscopy was performed. She underwent surgical management, including small bowel segmental resection and duodenojejunostomy, due to the jejunal mass with involvement of the stomach, pancreatic head, and mesentery of the transverse colon. The postoperative pathological results revealed a moderately differentiated adenocarcinoma of the jejunum.

The role of surgical intervention in patients with diabetic gastroparesis is unclear. We report a case of a 37-year-old man with a history of recurrent episodes of vomiting and long-standing type 2 diabetes mellitus. Esophagogastroduodenoscopy did not reveal any findings of reflux esophagitis or obstructive lesions. A gastric emptying time scan showed prolonged gastric emptying half-time (344 minutes) indicating delayed gastric emptying. Laboratory tests revealed elevated fasting serum glucose and glycosylated hemoglobin (HbA1c, 12.9%) and normal fasting C-peptide and insulin levels. We performed Roux-en-Y reconstruction after subtotal gastrectomy to treat gastroparesis and improve glycemic control, and the patient showed complete resolution of gastrointestinal symptoms postoperatively. Barium swallow test and gastric emptying time scan performed at follow-up revealed regular progression of barium and normal gastric emptying. Three months postoperatively, his fasting serum glucose level was within normal limits without the administration of insulin or oral antidiabetic drugs with a reduced HbA1c level (6.9%). Long-limb Roux-en-Y reconstruction after subtotal gastrectomy may be useful to treat severe diabetic gastroparesis by improving gastric emptying and glycemic control.
