At the beginning of the year of the rabbit, in the atmosphere of welcoming the new year and forging ahead, the Department of Hepatobiliary Medicine actively responded to the call of the head of the hospital to “strengthen the internal construction of the hospital” and successfully performed the first laparoscopic hemigastric fundoplication (Dor surgery) for a patient with reflux esophagitis in 309 hospital. The patient, a 55-year-old male from Heilongjiang province in the snowy forest plain, had suffered from reflux esophagitis for 7 years, manifesting as retrosternal pain, acid reflux and heartburn, and was treated with oral acid suppression and gastric mucosa protection drugs, but the symptoms still recurred and gradually worsened. Gastroscopy suggested that the dentate line, which was originally located at the lower end of the esophagus, had risen to 25 cm from the incisors, and was accompanied by obvious Barrit esophagus, biopsy found intestinal epithelial hyperplasia, and 24-hour PH test was obviously abnormal, this patient, if not solved the problem of esophageal reflux, not only affects daily life, but also may develop into a malignant tumor of the esophagus, so the patient urgently requested to fundamentally solve the problem of esophageal reflux. Therefore, the patient urgently needs to solve the problem of esophageal reflux. Gastroesophageal reflux disease is a common and frequent disease, but both patients and medical workers lack sufficient knowledge of the disease and often ignore its existence. Its pathogenesis is the relaxation and dilatation of the lower esophagus, resulting in the reflux of acidic gastric juice into the esophagus, which in turn erodes the esophageal mucosa and results in a series of symptoms such as acid reflux, pain, and asthma. For reflux esophagitis in which medical treatment is ineffective, minimally invasive surgical treatments are commonly available: 360oNissen fundoplication, 270o posterior fundoplication, and partial anterior or Dor hemi-fold fundoplication. The choice of the specific procedure requires a surgical plan based on the specific situation. It has been suggested that partial fundoplication is more physiologically correct and more easily tolerated by patients than the Nissen procedure. Patients of advanced age and patients with gastric motility disorders (e.g., loss of relaxation) generally require partial fundoplication. For patients with significant esophageal inflammation and mild obstructive symptoms, 180o fundoplication is appropriate to prevent postoperative esophageal stricture and aggravation of obstructive symptoms. After the patient was admitted to the hospital, Director Li Hucheng of the Department of Hepatobiliary Medicine led doctors Huang Hui, Wang Ruiguan, Wu Tiantian and Zhang Wei to carefully review the patient, consult relevant literature at home and abroad, understand the current situation and cutting-edge progress in the diagnosis and treatment of GERD, combine with the patient’s symptoms of mild obstruction, and after repeated discussions and consultation with relevant experts from the Armed Police General Hospital and the Second Artillery General Hospital, it was decided to make full use of the advantages of laparoscopic surgery in our hospital. The laparoscopic fundoplication (Dor hemigastric fundoplication) was performed. The operation was carried out in an orderly manner under the guidance of Professor Wu from the Second Artillery General Hospital. The patient required only two 1-cm incisions and two 0.5-cm incisions in the abdomen. Under laparoscopic surveillance, the ultrasonic knife was used to completely free the gastric fundus and esophagus, cut the short gastric vessels at the bottom of the stomach, and intermittently sutured both sides of the diaphragm foot to narrow the esophageal fissure to about 1.5 cm. The operation was successfully completed by folding the gastric fundus and wrapping the esophagus at 180°. The patient was discharged from bed 6 hours after the operation and started to eat a liquid diet 24 hours after the operation. On the third day after the operation, the gastric tube was removed and the symptoms of acid reflux and burning sensation behind the sternum before the operation completely disappeared and there was no choking sensation when eating. The first case of laparoscopic hemi-gastric fundoplication (Dor procedure) for reflux esophagitis with normal gastric motility in our hospital has been a complete success and achieved the ideal result. Since the establishment of the Third Department of Hepatobiliary Surgery in July 2010, all the comrades of the department have been active and aggressive, carrying out the first single-port laparoscopic cholecystectomy, the first laparoscopic liver resection, the first duodenoscopic two-way meeting bile duct stenting and precise liver resection and other new technologies in 309 Hospital, filling a number of gaps in our hospital, and winning the first prize for the increase in revenue in 2010 and the second prize for the progress of single index in 2010. In 2011, all the comrades of the department will continue to work hard, live up to the expectations of the public, climb to the top, and make new achievements to build 309 Hospital into a first-class general hospital of the whole army!
