Although it is difficult to define the term "aging" consensually, in medical fields, usually it means the progressive accumulation of irreversible degenerative changes leading to loss of homeostasis. It is supposable that there is also modest decline in the structure and function of several digestive organs. However, data about this subject are not enough. Main problem in studying aging digestive organ is that discrimination of primary senile change of the organ with secondary one from other senile diseases is not easy. That is, the prevalence of many non-digestive disorders which can badly affect the digestive functions is increasing by aging; for example, diabetes, malignancy, etc. To prove that some phenomenon is as result of pure senile change, it is necessary to exclude secondary one, but, the process is very complicated and difficult. In spite of this limitation, here, I will discuss the senile change of several digestive organs by aging, especially at the view of the gastrointestinal functions, with review of literatures.

OBJECTIVETo study a group of patients with abnormalities of esophageal motility in manometric investigation.

METHODSFrom 1990 to 1999, 14 patients with dysphagia (9), chest pain (3), or both (2) were studied. All patients denied symptoms of heartburn, regurgitation, odynophagia, epigastric discomfort, and investigation failed to show any evidence of ischemic heart disease. A perfused catheter with 4 separate lumens was used and connected to output transducers (Medtronic, PC Polygraf HR).

RESULTSOf the 14 patients, 11 had motor disorders of the esophageal body including simultaneous contractions without normal peristalsis (5), alternative occurrence of simultaneous contractions and normal peristalsis (3), aperistalsis (2) and very low amplitude peristalsis (1). Seven patients were diagnosed with motility disorders of the lower esophageal sphincter including incomplete relaxation or no relaxation on swallowing (6), short relaxation duration (1). Four patients had more than one abnormal manometric findings.

CONCLUSIONSNon-specific esophageal motility disorder is not a real diagnostic entity, but only a group of manometric abnormalities. The relationship between the symptoms of the patients and the manometric findings was analysed. It is uncertain that these disorders have a common etiology. The revision of these abnormalities is difficult because the pathogenesis is unknown.

OBJECTIVE: To summarize the diagnostic and therapeutic experience of primary cricopharyngeal achalasia and introduce new operandi modus. METHOD: Report the two cases we treated in 2008 and integrate published literature, and approach its diagnostic and therapeutic experience and make use of new operandi modus. RESULT: The diagnosis of primary cricopharyngeal achalasia is difficult, and we must apply exclusive diagnosis according to the examinations of fibrolaryngoscopy, esophagoscopy and barium meal et al. CONCLUSION Surgical treatment is the best option. Partial resection of cricopharyngeal muscle and upper esophageal ring-shaped muscle is superior to simple cricopharyngeal myotomy.

OBJECTIVETo evaluate the clinical application of 24-hour esophageal multichannel intraluminal impedance-pH monitoring technique in preterm infants.

METHODThis study enrolled 28 preterm (male 20, female 8) infants with symptoms suggestive of gastroesophageal reflux (GER) (frequent regurgitations, apnea, or transcutaneous oxygen saturation decreased). They had postmenstrual age from 26 to 32 weeks, median (28.9 ± 1.9)weeks, had birth weight from 850 to 1 700 g, median (1 250.4 ± 272.8)g, range 850-1700 g, and were studied at corrected gestational age from 28 to 40 weeks, median (34.5 ± 2.3)weeks. Combined measurement of esophageal pH and impedance was performed. The 24-hour pH-impedance recording was uploaded onto a portable storage card and for computer-assisted manual analysis, using a specialized software program. When values were distributed normally, they were presented as mean and standard deviation, compared using t test. When values were not distributed normally, they were presented as median, minimum and maximum. Median values were compared using the Mann-Whitney U non-parametric test. SPSS 17.0 software was used.

RESULTIn 28 preterm infants, 71.4% (20/28) had pathological acid refluxes with pH monitor, while 100% with combined measurement of esophageal pH and impedance. Gestational age, birth weight, corrected gestational age had no association with acid GER. Frequent regurgitations, apnea, or transcutaneous oxygen saturation decreased but there was no statistically significant difference between acid GER group and non-acid GER group. Eight cases had no pathological acid refluxes, but showed an increase of weakly acid refluxes than pathological acid refluxes group (P < 0.01) . The median number of reflux events in 24 hours for 28 cases was 64.5 (0-377) , 23.4% were acidic, while 76.4% were weakly acidic; 59.1% were liquid bolus refluxes, while 40.9% were mixed bolus refluxes. The positive ratio of symptoms related index and symptoms association probability were significantly increased combined measurement of esophageal pH and impedance versus pH monitor were used.

CONCLUSIONThe 24-hour esophageal impedance-pH monitoring technique was safe and had good tolerance. We confirmed that it detected more weakly acidic refluxes, liquid bolus refluxes, and mixed bolus refluxes. And it provided more evidence for explaining the relationship between GER and clinical manifestation.

OBJECTIVETo observe the clinical effect of unblocking the interior and purgation method on improving decreased gastrointestinal motility of post-operative esophageal cancer patients, and to study its mechanisms.

METHODS60 patients with post-operative esophageal cancer were randomly assigned to two groups, the treatment group and the control group, 30 in each group. Routine therapies were given to the two groups. Chinese drugs with unblocking the interior and purgation action was infused by enteral nutrition tube to patients in the treatment group, while normal saline was infused to those in the control group. The first flatus time, the first defecation time, the bowel tones recovery time after operation, and the total amount of the gastric juice draining between the first day and the third day after operation of all patients were recorded. Plasma motilin (MTL) and vasoactive intestinal peptide (VIP) contents were detected before operation and the fourth day after operation.

RESULTSThe first flatus time, the first defecation time, the bowel tones recovery time after operation, and the total amount of the gastric juice draining were less in the treatment group than in the control group, showing statistical difference (P<0.05, P<0.01). The post-operative MTL contents were higher and VIP contents lower in the treatment group than in the control group, showing statistical difference (P<0.05, P<0.01). There was no significant difference in plasmal MTL and VIP contents of the treatment group between before and after treatment (P>0.05). But there was significant difference in plasmal MTL and VIP contents of the control group between before and after treatment (P<0.01).

CONCLUSIONUnblocking the interior and purgation method could significantly promote the gastrointestinal motility recovery of post-operative esophageal cancer patients, showing good clinical effect.

OBJECTIVETo evaluate the effectiveness of endoscopic variceal ligation (EVL) in patients with different grades of liver function.

METHODSMELD scores were determined for 156 patients before their EVL operations. After the EVL these patients were followed-up and their survival rates were analyzed.

RESULTSFifty percent of the patients whose MELDs were less than or equal to 7 survived longer than 45 months after the EVL; in those with MELDs between 7 and 9, 50% of the patients survived 47.34 months; however, the figure for those whose MELD were more than 9 survived only 24.89 months. In the first two groups, 50% of the patient' survival duration was significantly longer than that of the third group. The difference was statistically significant.

CONCLUSIONEVL becomes an effective clinical way to treat hemorrhage of esophagus varicose veins. The survival rate for this procedure is directly correlated with the liver function of the patient before the EVL.

OBJECTIVETo investigate the clinical efficacy of Shenzhe Zhuyun mixture (SZM) in treating esophageal lesion in patients with systemic sclerosis.

METHODSSixty-four patients conforming to the inclusion criteria were randomly divided into 2 groups, the treated group and the control group treated respectively by SZM and cisapride, with the blank preparation imitating the contrast one, the treatment course to both groups was 2 months. The clinical efficacy, the changes in symptom scores of esophageal lesion, the orthostatic and clinostatic time of barium passing through esophagus, the clinostatic esophageal emptying index of barium, and the widest transverse diameter of ectatic esophageal segment, as well as the influence of treatment on patients' quality of life were observed.

RESULTSThe total effective rate in the treated group was superior to that in the control group (96.9% vs 56.2%, P < 0.01). Symptom of esophageal lesion was significantly improved after treatment in both groups (P<0.01), and the improvement in the treated group was better than that in the control group (P <0.01). The time of Barium passing through esophagus, both orthostatic and clinostatic, and the esophageal emptying index of barium were improved in the treated group (P < 0.01), but the change of the widest transverse diameter of ectatic esophagus was insignificantly improved. While in the control group, excepting the clinostatic time of barium passing through was improved (P<0.01), the other indexes showed no obvious change. Patients' quality of life was significantly improved in the treated group, but improvement didn't revealed in the control group.

CONCLUSIONSZM can reinforce esophageal dynamic function in patients with systemic sclerosis, it can be an effective TCM prescription in treating esophageal lesion for them.

OBJECTIVEAllgrove syndrome is a rare autosomal recessive disorder characterized by the triad of adrenal insufficiency, achalasia and alacrima and many cases have multi-systems disorder: endocrine, gastrointestinal tract, eyes and nervous system. This syndrome is also known as achalasia-addisonianism-alacrima syndrome or triple A syndrome. Allgrove syndrome is now known to be caused by mutations of AAAS gene encoding the aladin protein. In the present paper, we report a Chinese mainland girl with Allgrove syndrome with mutations in the AAAS gene.

METHODThe patient was a 7-year-old girl complained of coma and dark skin; she was treated as Addison disease for 2 years and had vomiting for 9 months before the second admission. Gene analysis was performed after extracting genomic DNA by amplification and sequencing of the specific fragments of AAA gene.

RESULTSThe patient was confirmed to have adrenal insufficiency at the age of 5 years and 6 months. During the second hospitalization, she was found to have a remarkable brisk reflexion, bilateral optic nerve atrophy, alacrima and achalasia besides ACTH resistance. The girl was born to consanguineous parents. Based on these findings, she was diagnosed as having Allgrove syndrome. Mutation analysis revealed a novel homozygous deletion of a single G, c.771delG, in exon 8 of the AAAS gene. This frame shift mutation was predicted to create a premature stop codon at locus 290, p.R258GfsX33, leading to a truncated and non-functioning aladin protein. Both the parents were heterozygous for the mutation.

CONCLUSIONThe clinical manifestations and AAAS gene mutations analysis confirmed the diagnosis of Allgrove syndrome. Gene analysis indicated that this syndrome is an autosomal recessive inherent disorder. ALADIN is significant for the normal cell function. When compared with reported cases, it seems that there are no remarkable relation between gene mutation loci and clinical manifestations in Allgrove syndrome.

Acute esophageal necrosis is uncommon in the literature. Its etiology is unknown, although cardiovascular disease, hemodynamic compromise, gastric outlet obstruction, alcohol ingestion, hypoxemia, hypercoagulable state, infection, and trauma have all been suggested as possible causes. A 67-year-old female underwent a coronary angiography (CAG) for evaluation of chest pain. CAG findings showed coronary three-vessel disease. We planned percutaneous coronary intervention (PCI). Coronary arterial dissection during the PCI led to sudden hypotension. Six hours after the index procedure, the patient experienced a large amount of hematemesis. Emergency gastrofibroscopy was performed and showed mucosal necrosis with a huge adherent blood clot in the esophagus. After conservative treatment for 3 months, the esophageal lesion was completely improved. She was diagnosed with acute esophageal necrosis. We report herein a case of acute esophageal necrosis occurring in a patient undergoing percutaneous coronary intervention.
