Reduced surgery for early gastric cancer has been actively performed because it can offer complete cure and a good postoperative quality of life.Pylorus-and vagus-preserving gastrectomy (PPG) is one form of function-preserving surgery.Laparoscopic surgery has been widely applied for the treatment of gastric cancer due to its advantages including low invasiveness,minimal bowel paralysis,earlier postoperative healing and nerve and gastric function preservation.Therefore,laparoscopic pylorus-and vagus-preserving gastrectomy (LAPPG) for the treatment of early gastric cancer is welcomed by surgeons.From May 2004 to April 2013,12 patients with early gastric cancer received LAPPG in the First Affiliated Hospital of Dalian Medical University.All the patients were followed up for 3-74 months.One patient died of gastric cancer liver metastasis at postoperative month 22.The 5-year cumulative survival rate was 86％.LAPPG preserves nerve function and limits surgical injury,it is one of the ideal surgical methods for the treatment of early gastric cancer.

Objective To investigate the surgical techniques and clinical efficacy of laparoscopic intersphincteric resection (ISR) in the treatment of low rectal cancer.Methods A retrospective descriptive study was performed.The clinical data of 12 patients who underwent laparoscopic low rectal anterior resection combined with ISR at the First Affiliated Hospital of Dalian Medical University from May 2014 to October 2014 were collected.The patients underwent abdominal operation including total mesorectal excision (TME) + sphincter mobilization,then transanal intersphincteric resection,finally colinic anal-anal anastomosis.The operation time,volume of intraoperative blood loss,number of lymph node dissected,postoperative complications,time to anal exsufflation,duration of hospital stay,duration of postoperative hospital stay,pathological stage and follow-up were observed.The patients were followed up by outpatient examination and telephone interview at month 1,3 and 6 after operation up to April 18,2015.The follow-up included the prognosis of patients and the recovery of anal function.The function of defecation was evaluated by Wexner scoring system and Kirwan grading.Measurement data with normal distribution were presented as (x) ± s.Results All the 12 patients were completed laparoscopic surgery without conversion to open surgery.Eight patients underwent partial internal anal sphincter resection,and 4 underwent subtotal resection.Four patients in T3 stage underwent lateral lymph node dissection preserving the left colonic artery,hypogastric nerve and pelvic nerve.The operation time was (290 ± 35) minutes.The volume of intraoperative blood loss was (124 ± 80) mL.The number of lymph nodes dissected was 17 ± 8,and the number of positive lymph nodes was 0-4.The distance of the distal margin was (2.0 ± 0.5) crm,and the margin was negative.All the 12 patients were not complicated with infection,bleeding,anastomotic leakage,anastomotic stenosis and other complications.The time to postoperative anal exsufflation was (3 ± 1)days,duration of hospital stay was (20 ± 3) days,and duration of postoperative hospital stay was (12 ± 3) days.The results of TNM stage showed 3 cases of pT1 stage,5 cases of pT2 stage,4 cases of pT3 stage,10 cases of pN0 stage,1 case of pN1 stage,1 case of pN2 stage,8 cases of Ⅰ stage,2 cases of Ⅱ stage and 2 cases of Ⅲ stage.All the 12 patients were followed up for 6-11 months.The defection frequency and the Wexner score at month 1,3 and 6 after operation were 12 ±7,15 ±3,9 ±5 and 13 ±4,5 ±3,10 ±3,respectively.Of the 12 patients,the number of patients with satisfactory Kirwan score,flatus incontinence and loose stool was 1,3,8 at month 1 after operation,3,3,6 at month 3 after operation,10,2,0 at month 6 alter operation,respectively.Conclusion Laparoscopic ISR is effective in the treatment of low rectal cancer.

Objective: To evaluate the effect of nutritional support for lung transplantation patients.Methods: The lung transplantation patient received perioperative enteral nutrition(EN) .Exogenous glutamine(Gln) and recombinant human growth hormone(rhGH) were postoperatively used for 7-14 days.Results: The patients weight increased from 53 kg to 55 kg. No respiratory failure and acute rejection occurred postoperatively. The patient recovered fluently.Conclusion: Appropriate perioperative nutritional support and postoperative metabolic intervention can facilitate the recovery of lung transplant patient.

Objective: Enteral nutrition was used to correct the malnutrition in the patients suffered from esophageal rupture postoperatively. Methods: The naso intestinal tube was placed during operation and the enteral nutrition was used postoperatively. The albumin, prealbumin and transferrin were measured before and day1, 5, 8 and 12 after operation. Results: All 27 patients were discharged with no death. Albumin, prealbumin and transferrin decreased on the 1st day postoperatively and reached the preoperative level on the fifth postoperativeday. Conclusion: Enteral nutrition plays an important role in the postoperative treatment for esophageal rupture.
