OBJECTIVETo explore the effect of immune-enhanced enteral nutrition (IEN) together with recombined human growth hormone (rhGH) on patients after total gastrectomy.

METHODSForty-eight patients after total gastrectomy were randomly divided into EN group (n=16), IEN group (n=16) and IEN+ rhGH(n=16) group. Nitrogen balance, nutritional status, immune function and lassitude degree were compared among 3 groups.

RESULTSIEN+rhGH group had better efficacy as compared to EN and IEN group in improving postoperative nutritional status, immune function, nitrogen balance and lassitude degree, and recovered to normal level after 7 days. All the indexes of IEN+rhGH group except CD8 were improved significantly on the 10th day after operation as compared to those of EN group[total protein(66.8 +/- 2.0)g/L vs (65.8 +/- 0.9)g/L, CD3(66.1 +/- 6.3)% vs (60.5 +/- 5.6)%, Christensen score (4.6 +/- 0.9) vs (6.3 +/- 0.9), all P<0.05].

CONCLUSIONEarly application of IEN combined with rhGH plays an effective role in improving protein metabolism and immune function for patients after total gastrectomy in short period.

OBJECTIVETo investigate the potential benefits of postoperative nutrition in malnourished patients with gastrointestinal cancer.

METHODSA total of 646 malnourished patients with gastrointestinal cancer defined by the subjective global assessment (SGA) were randomly divided into parenteral nutrition group (n=215), enteral nutrition group (n=215) and conventional group (n=216). Two nutritional regimens were designed to be isocaloric 125.5 kJ(30 kcal).kg(-1).d(-1) and isonitrogenous 0.25 g.kg(-1).d(-1) for 7 postoperative days. Conventional group did not receive artificial nutrition before and after surgery. Postoperative complications, mortality and postoperative length of hospital stay were compared.

RESULTSAll baseline and surgical characteristics were comparable among 3 groups. Overall postoperative mortality was 1.5%, and no difference was observed among 3 groups. Postoperative complications occurred in 61(28.4%) patients in enteral nutrition group, 72(33.5%) in parenteral nutrition group, and 97 (44.9%) in conventional group (P=0.000 vs enteral nutrition group; P=0.001 vs parenteral nutrition group). Postoperative length of hospital stay was (9.8+/-3.4) d in enteral nutrition group, (11.2+/-5.0) d in parenteral nutrition group, and (14.5+/-7.1) d in conventional group (P=0.001 vs enteral nutrition group; P=0.003 vs parenteral nutrition group).

CONCLUSIONSPostoperative artificial nutrition support is beneficial to the malnourished patients with gastrointestinal cancer, which improves postoperative outcome. Early enteral nutrition significantly reduces the infectious complication rate and length of postoperative hospital stay as compared with parenteral nutrition.

OBJECTIVETo evaluate the value of reoperation for local recurrence of rectal carcinoma.

METHODSThe data of 62 cases with post-operative local recurrence of rectal carcinoma were analyzed retrospectively.

RESULTSAll the 62 patients received reoperation. Thirty two of those patients were treated with radical resection (16 patients combined multiple organ resection), 6 palliative resection, 11 colostomy, and 13 laparatomy only. The 1-, 3- and 5-year survival rates in the patients accepted radical resection were 90.6%, 59.4% and 18.8% respectively. But in patients undergone palliative resection and combined therapy, survival time was 6-24 months with median survival time of 16 months. The patients, accepted laparatomy and intra-abdominal chemotherapy, all died within 2-14 months postoperatively. For patients with postoperative recurrence time >5 years, <2 years and 2-5 years, the reoperation resection rates were 100%(11/11), 62.9%(22/35), and 31.3%(5/16) respectively, and there were significant differences among 3 groups (P<0.01). The rate of reoperation resection of pure local recurrence was 80.0%(32/40). The rate of reoperation resection of local recurrence, associated with near organ invasion, was 27.3%(6/22). The difference was significant(P<0.01). The reoperation resection rate of first operation with Dixon or Miles was 61.9%(26/42) and 30.0%(6/20), and the difference was significant as well(P<0.05).

CONCLUSIONSThe recurrence of rectal carcinoma still needs positive operation in order to prolong the survival time and improve the quality of life of the patient. First operative procedure, post-operative recurrence time and recurrence type are important factors of reoperative resection.

OBJECTIVETo investigate the clinicopathologic factors related with recurrence and prognosis after surgical resection for anorectal melanoma.

METHODSThe clinicopathologic factors related to recurrence and prognosis of 50 patients with anorectal melanoma after surgical resection were retrospectively analyzed using univariate and multivariate methods.

RESULTSForty-seven patients underwent radical operation, including 31 abdominoperineal resection (APR) and 16 sphincter preserving operation. The local recurrence rates were 16.1%(5/31) and 68.8%(11/16) respectively. chi(2) analysis revealed that operation pattern was associated with local recurrence rate. The 5-year survival rate was 18.2%. Univariate analysis revealed that single tumor, intramural infiltration and operation pattern were related with prognosis. Multivariate analysis revealed that intramural infiltration was the most important prognostic factor for anorectal melanoma.

CONCLUSIONSThe prognosis of anorectal melanoma is poor. Early diagnosis and treatment are important for the improving of curative effect.

OBJECTIVETo investigate the clinicopathologic characteristics and prognosis of multiple primary synchronous colorectal carcinoma (synchronous CRC) and single colorectal carcinoma (single CRC).

METHODSClinicopathological data of 39 patients with synchronous CRC and 528 patients with single CRC from May 1996 to June 2001 were reviewed retrospectively.

RESULTSThe patients with synchronous CRC accounted for 6.9% of all the patients with colorectal carcinoma treated in our hospital during the same period. Compared with concurrent lesions, Dukes stage of the index lesions of synchronous CRC was more developed and the lymph node metastasis and vessel invasion occurred more frequently. In addition, it also had poorer differentiation. There were significant differences of Dukes stages and lymph node metastasis between the index lesions and single CRC. The incidence of adenomatous polyp in synchronous CRC was higher than that in single CRC(59.0% vs 25.0%,P<0.01). The sensitivity of preoperative colonoscopy examination was 76.9%, which was significantly higher than that of barium examination and exploration during operation. The total 5-year survival rate of synchronous CRC was significantly lower than that of single CRC (5.1% vs 28.2%,P=0.042), and no significant difference of total 5-year survival rate was found between single CRC patients and synchronous CRC patients undergone radical operation. Synchronous CRC patients undergone radical operation had longer survival as compared to those undergone palliative operation(P<0.01). Multivariate analysis indicated that Dukes stages, lymph node metastasis, vessel invasion and the type of operation were independent prognostic factors of synchronous CRC.

CONCLUSIONSSynchronous CRC and single CRC are not always similar in clinicopathologic characteristics and prognosis. Early finding, early diagnosis and radical operation are the keys to improve the survival rate of synchronous CRC.

OBJECTIVETo investigate the effect of spleen preservation on the outcome of radical resection for cardia cancer.

METHODSData of 108 cardia cancer patients(Siewert types II and III ), undergone radical resection with D(2) or D(3) lymphadenectomy between July 1994 and December 2003 in our department, were analyzed retrospectively. Survival status was ascertained on December 2004. Of these 108 patients, 38 underwent splenectomy and 70 splenic preservation. Clinicopathological features and outcomes of the splenectomy and non-splenectomy groups were compared.

RESULTSSeventy-four patients (68.5%) had lymph node involvement; 18 patients (16.7%) had involvement of lymph nodes in the splenic hilus. Postoperative morbidity in two groups was similar. Overall 5-year survival rate in the non-splenectomy group was significantly higher than that of the splenectomy group (38.7% vs 16.9%, P=0.008). Multivariate regression analysis indicated that tumor invasion (P=0.009) and lymph node metastasis (P=0.001) were independent prognostic factors rather than splenectomy. Although splenectomy was associated with survival, it was not an independent prognostic factor (P= 0.085).

CONCLUSIONSSplenectomy does not improve survival of patients undergone curative resection for gastric cardia cancer. Thus, the spleen should be preserved in patients without direct cancer invasion of the spleen.

OBJECTIVETo examine the relationship between the dissected lymph-node number and the prognosis in D(2) gastrectomy for gastric cancer.

METHODSFrom January 1996 to January 2005, 457 patients with primary gastric cancer undergone gastrectomy with different extent of lymphadenectomy in our hospital were followed-up in term of prognostic benefit.

RESULTSIn lymph-node metastasis group, the 1-, 3-, 5-year survival rates were 82.4%, 49.0%, 33.4% with dissection of >20 nodes and 71.5%, 49.7%, 40.1% with dissection of 16-20 nodes. In the group without lymph-node metastasis, the 1-, 3-, 5-year survival rates were 98.2%, 92.7%, 84.7% with dissection of >20 nodes and 94.0%, 89.7%, 81.4% with dissection of 16-20 nodes. Whether or not it had lymph-node metastasis, the survival curve failed to show any significant difference with regard to the extent of lymph node dissection.

CONCLUSIONSAs to lymphadenectomy for gastric cancer, it is enough to excise the lymph node between 16 and 20. The number of excised lymph node should not be overemphasized unless it is metastasized.

OBJECTIVETo summarize the clinical characteristics of mesenteric arterial embolism (MAE) and mesenteric arterial thrombosis (MAT), and to clarify the diagnosis and treatment status of MAE and MAT in China.

METHODSA retrospective analysis of 111 cases suffering from MAE or MAT was performed. Data of these cases were collected from Chinese Journal Full-text Database from 1994 to 2006.

RESULTSThere were 61 cases (54.9%) with MAE and 50 cases (45.1%) with MAT. Fifty-two patients (46.8%) had arterial fibrillation. Ninety-seven cases (87.4%) were diagnosed by exploratory laparotomy or autopsy, and 14 cases (12.6%) by imageology. Embolism or thrombosis in superior mesenteric artery (SMA) accounted for 92.8%, 4.5% in SMA plus inferior mesenteric artery. 15.2%(14/92) necrosis were located in jejunum or ileum, 39.1%(36/92) in jejunum and ileum, 38.0%(35/92) in jejunum, ileum and colon. Thrombolysis or anticoagulation in artery were operated in 7 cases(6.3%). Extraction of embolism or thrombosis in operation were implemented in 18 cases(16.2%). Intestinal resection were finished in 76 cases(68.5%). Sixty-eight patients (61.3%) were misdiagnosed. Sixty-three cases (60.6%) died.

CONCLUSIONThe manifestation of MAE or MAT is quite complicated and changeable, so that many cases are misdiagnosed. The clinic and image characteristics of MAE and MAT have not been well known by doctors.

OBJECTIVETo evaluate the clinical practice of laparoscopic rectopexy in the treatment of severe rectal prolapse.

METHODSFrom March 1998 to February 2007, 4 cases of complete rectal prolapse, including 1 male and 3 female,ranged 21-82 years old, were treated by laparoscopic rectopexy. In one case, the posterior wall of rectum was freed and elevated, and pre-rectal introcession was closed by silk suture, then the posterior wall was suspended and fixed on sacral promontory fascia, finally the sigmoid colon was fixed by sutures on the fascia of left psoas major. In other three cases, insertion of mesh was performed. Rectum was freed and elevated to the level of levalor ani. A sheet of T-shape polypropylene mesh was placed posterior to the rectum, whose lower margin was at the level of levator ani and wrapped around the rectum covering except the anterior wall. The free margin of the mesh was sutured on the muscular layer of rectum, then the mesh was put posterior to the rectum and fixed on the sacral promontory fascia by clipping to repair hernia. After that, the pelvic peritoneum was closed, and finally the sigmoid colon was fixed by sutures on the fascia of left psoas major.

RESULTSFour operation procedures were completed successfully. There was no conversion operation. The time was consumed 92.5 (80-100) min, and the bleeding amount was 6.5 (5-10) ml. No post-operative complications were found. Urine incontinence and encopresis were relieved. No recurrence and constipation was found after 2 months to 3 years follow up postoperatively.

CONCLUSIONLaparoscopic rectopexy is a safe, workable and effective procedure, which can reduce operative trauma and shorten hospitalization time.

OBJECTIVETo evaluate the long-term therapeutic efficacy of extended parietal cell vagotomy (EPCV) in the treatment of duodenal ulcer complicated with acute perforation.

METHODSTherapeutic efficacy of EPCV in 176 cases subjected to duodenal ulcer with acute perforation since 1979 was evaluated, including postoperative complication, ulcer recurrence rate, gastric empting function, endoscopic and radiographical examination, nutritional status and Visick classification.

RESULTSAmong 176 patients, 153 (86.9%) cases were successfully followed-up for 5 years after operation. No operative death was found. Postprandial superior belly fullness occurred in 13 cases (8.5%) and heartburn in 12 cases (7.8%), which could be relieved by Domperidone. Adhesive ileus was noted in 4 cases (2.6%) which was cured by adhesiolysis. The total ulcer recurrence rate was 2.6% (4 cases) within 2 to 3 years after operation. Superficial gastritis occurred in 21 cases (13.7%) and duodenal bulb in 31 cases (20.3%). Sinus ventriculi vermicular motion was good and gastric emptying was normal. No anemia was found. Body weight gained in 116 cases (75.8%). One hundred and forty-six cases(95.4%) were reforming Visick grade I and II , 3 cases(2.0%) grade III , and 4 cases (2.6%) IV .

CONCLUSIONSEPCV is convenient for performance with low postoperative complication rate. Its long-term efficacies are quite good, which including normal nutritional status, high quality of life and low ulcer recurrence rate. EPCV is one of effective and safe treatments for duodenal ulcer complicated with acute perforation.
