The clinical data of 3 cases of Ramsay-Hunt syndrome concurrent with ipsilateral vocal cord paralysis were retrospectively analyzed, and the relevant literatures were also reviewed. Ramsay-Hunt syndrome is a kind of disease characterized by heavy ear pain, herpes zoster oticus and inner ear neurologic symptoms, which can also affect the vocal cords and give rise to vocal cords paralysis. Ramsay-Hunt syndrome can cause multiple in flammation of cranial nerves. The viral infection can also involve the 3rd and 10th cranial nerves. It mainly damage the facial nerve, followed by the involvement of vestibulocochlear nerve. The vagus nerve damage is rare, so the relevant clinical reports are less. It is important to take the objective data as well as subjective symptoms of the patients into consideration to make a definite diagnosis, so that we can treat it as soon as possible to achieve better curative effect.

Objective To explore the efficacy and feasibility of laparoscopy-assisted radical total gastrectomy in the treatment of cancer of the cardia and fundus. Methods The clinical data of 176 patients with cancer of the cardia and fundus who received total gastrectomy at the Union Hospital of Fujian Medical University from April 2007 to April 2009 were retrospectively analysed. Among the patients, 81 received laparoscopic total gastrectomy ( LATG group) and 95 received open total gastrectomy ( OTG group). The patients' intra- and postoperative conditions, clearance of lymph nodes, morbidity and mortality were analysed using the chi-square test and t test. Results All the operations were successfully carried out. The intraoperative blood loss was (98 ± 84) ml in the LATG group and (339±245) ml in the OTG group. Three patients in the LATG group and 19 in the OTG group received blood transfusion. The time to first flatus and postoperative hospital stay were (3.9 ± 1.1) days and (13 ± 5) days in the LATG group, and (5.0 ± 1.6) days and (15 ± 5) days in the OTG group, respectively.There were significant differences in the time to first flatus and postoperative hospital stay between the LATG group and OTG group (t = 4.16, x2 = 6.82, t = 4. 57, 2. 83, P < 0. 05). The mean number of lymph nodes dissected was 28 ± 12 in the LATG group and 29 ± 11 in the OTG group, with no significant differences between the two groups (t = 0. 42, P >0.05). The number of lymph nodes dissected in patients with T1, T2 and T3 stages were 21 ±8, 25 ±7 and 29 ± 11 in the LATG group, and 29 ± 12, 31 ±9 and 28 ± 11 in the OTG group, respectively,with no significant differences between the two groups (t = 1.53, 1.90, 0. 65, P > 0.05). The morbidity and mortality rates of the LATG group were 11%( 9/81 ) and 0, and 19% ( 18/95 ) and 1% ( 1/95 ) in the OTG group, with no significant differences between the two groups (x2 = 2.07, 1.18, P > 0.05). Conclusion The efficacy of laparoscopy-assisted radical total gastrectomy is similar to that of open gastrectomy. Laparoscopy-assisted radical total gastrectomy is a safe and feasible procedure that leads to quick postoperative recovery.

8.Therapy of both surgical and non-surgical related complication of gastric cancer for the elderly.
Chinese Journal of Gastrointestinal Surgery 2016;19(5):502-506
Gastric cancer is one of the most common digestive malignant tumors. More and more elderly gastric cancer patients are diagnosed and need to undergo surgical treatment as the population ages. Since the elderly patients decrease in organ function and increase in internal diseases, the tolerance to anesthesia and surgery is poor. As a result, the incidence of surgical and postoperative complications is obviously higher. Complications can be divided into surgical complications and non-surgical related complications. Surgical complications consist mainly of hemorrhage, anastomotic leakage, anastomotic dehiscence and intestinal obstruction, while non-surgical related complications include deep venous thrombosis, pulmonary infection, anesthesia-related complication, abdominal infection, urinary infection, incision infection, poor wound healing, gastroparesis, gastroesophageal reflux disease, dumping syndrome and so on. Hence, we should consider more about the elderly patients' physical condition instead of the extent of radical operation. To reduce complications, we should evaluate the organ function and take an active role in underlying diseases before operation. Meanwhile, high quality nursing, powerful analgesia, anti-inflammation, keeping water electrolyte balance and nutrition support are also required postoperatively. Moreover, laparoscopic surgery and enhanced recovery after surgery (ERAS) can reduce the postoperative complications in elderly patients with gastric cancer as well. Further prospective randomized controlled trials about elderly gastric cancer should be carried out in the future, which can provide advanced evidences for treatment.
