Objective To investigate the management of complications after laparoscopic adjustable gastric banding (LAGB).Methods The clinical data of 83 obese patients who were treated by LAGB at the Nankai Hospital from September 2005 to June 2011 were retrospectively analyzed.The complications after LAGB were analyzed.The adjustable gastric band was installed under laparoscope so as to form a small gastric pouch with a volume ranged between 20-30 ml.The water pump was fixed in the rectus abdominis anterior sheath under the appendix ensiformis.The gastric band was adjusted according to the changes of the body weight,symptoms after diet and results of imaging examination of upper gastrointestinal tract.Patients were followed up via out-patient examination and phone call till July 2013.Results The incidence of complications of the 83 patients was 44.6％ (37/83).Six patients had short-term complications and 31 patients had long-term complications.The short-term complication mainly presented as post-prandial vomiting.The symptoms of 5 patients were relieved by changing of eating habit.The condition of 1 patient was severe,and the symptom was relieved 5 days later after fasting and nutritional support.For the 31 patients with long-term complications,25 were complicated with band erosion into gastric lumen via gastric wall (6 patients were complicated with infection of the water pump site),and they were cured by removal of band laparoscopicly.Ten patients were complicated with water pump-related complications,including 6 with infection of the water pump site and 4 with pump migration.The water pumps of the 4 patients with pump migration were surgically removed.Two patients had band slipping to the stomach.The band was restored to the original place after removing the liquid from the band and reducing the food intake,and then the position of the band in 1 patient was restored to normal,and no change was observed in another patient,and the band was removed laparoscopicly.Conclusions The incidence of complications after LAGB is high,and it increases as the time passes by.Most of the long-term complications after LAGB need to be treated by reoperation.

Objective To investigate the clinical characteristics and feasibility of laparoscopic repair of giant hiatal hernia. Methods From January 2008 to August 2010, 25 consecutive patients with giant hiatal hernia underwent laparoscopic repair. Crural closure was performed by means of two or three interrupted nonabsorbable sutures plus a tailored PTFE/ePTFE composite mesh. It was patched across the defect and secured to each crura with staples. Laparoscopic fundoplication was performed concomitantly in 16 cases according to the specific conditions of patients. Para-operative clinical parameters were recorded. All patients were routinely followed up. Clinical outcomes were collected and analyzed. Results All laparoscopic surgeries were accomplished successfully. The operating time was 85 -210 minutes (mean, 106 minutes) ,the operative blood loss was 55 - 150 ml( mean, 94 ml) ,the postoperative hospital stay was 4 -21 days( mean, 6.8 days). The symptoms in most cases were adequately relieved after operation. There was no severe postoperative morbidity. After the follow-up period of 3 - 35months ( mean, 13.6 months), the satisfaction rate of surgery was 88%. 4 cases had mild symptom recurrence of acid reflux.Hiatal hernia recurrence occurred in 1 case. Conclusions Laparoscopic repair of giant hiatal hernia is a safe and effective minimally invasive procedure, with the advantages of minimized trauma, quick recovery and reliable effect. The use of a tailored PTFE/ePTFE composite mesh ( Bard CruraSoft Mesh)for giant hiatal hernia proved to be effective in reducing the operation time and technique demands, and the rate of postoperative hernia recurrence, with a very low incidence of mesh-related complications.

Objective To investigate the feasibility and clinical value of laparoscopic surgery in treating patients with gastroesophageal reflux disease. Methods From September 2001 to August 2009, 372 patients with gastroesophageal reflux disease undertwent laparoscopic fundoplication, including 146 cases of Nissen fundoplication, 79 Toupet fundoplication, and 147 anterior 180 degrees partial fundoplication. Para-operative clinical parameters were recorded. All patients were routinely followed up. Clinical outcomes were collected and analyzed. Results Laparoscopic surgery was successfully performed in all patients, and no conversions were required. The operating time was 50 -210 minutes (mean, 85 minutes), the operative blood loss was 40 - 150 ml( mean, 86 ml) ,the postoperative hospital stay was 3 - 21 days( mean, 4.3 days ). The symptoms in most cases were adequately relieved after operation. There were no severe postoperative morbidity and mortality. Endoscopy, radiology, esophageal manometry and 24-hour pH monitoring were repeated 3 months after surgery. After the follow-up period of 3 -63 months ( mean, 27.3 months), the satisfaction rate of operation was 92.57%. 19 cases had mild dysphagia when eating solid food. Symptoms recurrence of acid reflux occurred in 6 cases, which were controlled by antacid medications. Hiatal hernia recurrence occurred in 1 case. Conclusions Laparoscopic operation should be the method of choice to treat the moderate to severe gastroesophageal reflux disease, with the advantages of minimized trauma,quick recovery, safety,feasibility and reliable effect. According to individual condition of patients, appropriate fundoplication procedure should be employed carefully to ensure results of operations, reduce operating difficulties and the rate of postoperative complications.
