RESUMO

Objective@#Acoustic pharyngealmetry technology is utilized to evaluate the change and clinical significance of obstructive sleep apnea-hypopnea syndrome (OSAHS) patients caused by non-upper airway structural factor and normal individuals′ PWF(pharyngeal wall floppiness).@*Methods@#Acoustic pharyngealmetry instrument of Ecconvision was utilized to examine 102 OSAHS patients and 50 normal individuals, separately recorded their volume of pharyngeal cavity in sit or supine position, calculated PWF in sit or supine position, and SPSS 12.0 of tware was used to analyze data.@*Results@#PWF was 0.14±0.09 in sit position and PWF was 0.21±0.10, (t=5.96, t=9.63, P<0.001)in supine position of OSAHS group, which were all significantly higher than those of control group. PWFs in supine position of OSAHS group and control group were evidently higher than PWF(t=-11.91, P<0.001; t=-2.32, P=0.025) in sit position. ΔPWF(PWF_supine-PWF_sit)was 0.063±0.054 in OSAHS group which was significantly greater than in control(F=41.173, P<0.01). PWF in sit position and supine position were all positively related with age(r=0.714, r=0.735, P<0.001)while irrelevant with BMI(P>0.05).@*Conclusions@#PWF can be utilized to be an index to reflect the physiological feature of upper airway. PWF can more precisely reflect upper airway collapsibility of OSAHS patients on the condition of PWF in supine position. Pharyngeal wall floppiness quantified as a high PWF index is a non-structure vital factor of OSAHS patients and plays a role of guiding us to make personal treatment plans for OSAHS patients.

RESUMO

Objective@#To explore the factors influencing the sexual function of the male patients with obstructive sleep apnea (OSA).@*METHODS@#Using Arizona Sexual Experience Scale (ASEX) and Epworth Sleepiness Scale (ESS), we conducted a questionnaire investigation among 81 male patients with OSA aged 40.5 ± 8.6 years and 35 healthy volunteers aged 38.8 ± 10 years. According to the sex drive (SD) score in ASEX, we divided the OSA patients into an SD reduction group (SD score = 4, n = 32) and a non-SD reduction group (SD score <4, n = 49), compared the clinical data and polysomnographic (PSG) indexes, and analyzed the factors influencing SD by evaluating the association of the PSG indexes with the SD score.@*RESULTS@#The OSA patients scored significantly higher than the healthy controls in ESS (8 ± 5 vs 5 ± 4, P <0.05) and ASEX (15 ± 4 vs 10 ± 2, P <0.05), and so did the patients of the SD reduction group than those of the non-SD reduction group in ESS (9 ± 5 vs 6 ± 5, P <0.05) and saturation impair time below 90% (SIT90) (41.01 ± 26.95 vs 21.87 ± 19.03, P <0.05). Multivariate regression analysis revealed that the SD score was significantly correlated with age (β = 0.25, P <0.001) and SIT90 (β = 0.4, P <0.001) in the OSA patients.@*CONCLUSIONS@#OSA affects various aspects of the sexual function, particularly SD, of the patient. The duration of hypoxia and age of the patient are independent risk factors for SD reduction, which can be considered as a main clinical symptom of OSA.

RESUMO

<p><b>OBJECTIVE</b>To investigate the effect of andrographolide (AD) on proliferation, cell cycle and apoptosis of human gastric cells line BGC-823.</p><p><b>METHODS</b>MTT assay, flow cytometry and Annexin-V/PI double-staining flow cytometry assay were used to evaluate the effect of AD on proliferation, cell cycle and apoptosis of BGC-823 cells respectively. Optical microscope and transmission electron microscopy were used to observe the cell morphological changes.</p><p><b>RESULTS</b>A time- and concentration-dependent proliferative inhibition effect of AD was demonstrated in BGC-823 cells. AD concentration lower than 7.5 mg/L possessed weak inhibitory effect,while concentration between 15.0-60.0 mg/L possessed higher inhibitory effect. The concentration higher than 60.0 mg/L had no significant increase of inhibitory effect. IC50 of AD at 24, 48 and 72 h was (35.3±4.3), (25.5±3.5) and (18.2±2.7) mg/L respectively. Compared with the negative control group, the number of G0/G1 phase cells increased significantly (P<0.05), while the number of S and G2/M phase cells decreased after incubation with AD for 48 h, and the alteration was in a concentration-dependent manner. AD arrested BGC-823 cells at the G0/G1 phase of the cell cycle. After incubation with 7.5, 10.0 and 15.0 mg/L AD for 24 h, the early apoptotic rates of BGC-823 cells were (19.3±4.7)%, (29.4±4.1)% and (52.7±6.7)% respectively, and the late apoptotic rates were (10.8±1.8)%, (10.9±4.7)% and (14.7±4.8)% respectively. Both the early apoptotic rates and the late apoptotic rates increased significantly compared to the control group (all P<0.05),and the alteration was in a concentration-dependent manner.</p><p><b>CONCLUSION</b>Andrographolide can inhibit BGC-823 cells proliferation, arrest BGC-823 cells in G0/G1 phase and induce apoptosis, and may be a potential traditional Chinese medicine with anti-cancer effect.</p>

RESUMO

<p><b>BACKGROUND</b>Andrographolide has been shown to have anticancer activity on diverse cancer cell lines representing different types of human cancers. The aim of this research was to investigate the anticancer and apoptotic effects of andrographolide on the BGC-823 human gastric cancer cell line.</p><p><b>METHODS</b>Cell proliferation and IC50 were evaluated using MTT assay, cell-cycle analysis with flow cytometry apoptotic effects with Annexin-V/propidium iodide double-staining assay, and morphologic structure with transmission electron microscopy. Immunohistochemistry and reverse-transcription PCR was used to analyze Bcl-2, Bax, and caspase-3 expressions.</p><p><b>RESULTS</b>Andrographolide showed a time- and concentration-dependent inhibitory effects on BGC-823 cell growth. Compared to controls, the number of cells in the G0-G1-phase increased significantly, S and G2-M-phase cells decreased after 48 hours of treatment with andrographolide, and both early and late apoptotic rates increased significantly compared to the controls, all in a concentration-dependent manner. Bax and caspase-3 expressions were markedly increased, and Bcl-2 expression was decreased.</p><p><b>CONCLUSIONS</b>Andrographolide inhibits BGC-823 cell growth and induces BGC-823 cell apoptosis by up-regulating Bax and caspase-3 expressions and down-regulating Bcl-2 expression. Andrographolide may be useful as a potent and selective agent in the treatment of human gastric cancers.</p>

RESUMO

<p><b>OBJECTIVE</b>To investigate the association of AKR1B10 expression in gastric cancer tissues with clinicopathologic features and prognosis of gastric cancer patients.</p><p><b>METHODS</b>Real-time polymerase chain reaction (RT-PCR) was conducted to detect AKR1B10 mRNA expression in gastric cancer and adjacent gastric mucosa tissues (n=36). AKR1B10 protein expression was measured by immunohistochemistry in primary gastric cancer tissues (n=100) and non-tumorous gastric mucosa tissues (n=70).</p><p><b>RESULTS</b>RT-PCR results confirmed that AKR1B10 was significantly down-regulated in gastric cancer tissues compared with that in paired adjacent mucosa [8.3% (3/36) vs. 91.7% (33/36), P=0.000]. Immunohistochemistry revealed that the percentage of AKR1B10 positive specimens in gastric carcinoma was lower than that in normal specimens [33.0% (33/100) vs. 92.9% (65/70), P=0.000]. The frequencies of positive AKR1B10 in patients was significantly correlated with tumor size (P=0.000), invasive depth (P=0.004), lymph node metastasis (P=0.028), distant metastasis (P=0.031) and TNM stages (P=0.000). The 5-year survival rate of positive AKR1B10 group was significantly higher as compared to negative group (60.6% vs. 32.8%, P<0.01).</p><p><b>CONCLUSION</b>The down-regulation of AKR1B10 expression in gastric cancer may be associated with the progress of gastric cancer is suggestive of poor prognosis.</p>

RESUMO

<p><b>OBJECTIVE</b>To investigate the association of SOX9 expression and clinicopathologic factors and prognosis of gastric cancer.</p><p><b>METHODS</b>A retrospective cohort study including 112 gastric cancer patients admitted to the Zhejiang Provincial People's Hospital from 2004 to 2006 was performed. Immunohistochemical analysis was used to evaluate the expression of SOX9 in the 112 specimens of gastric cancer tissues and 70 non-cancerous tissues adjacent to the tumor.</p><p><b>RESULTS</b>Low expression of SOX9 was seen in 5(7.1%) tissues out of 70 non-cancerous tissues adjacent to the tumor. A total of 94(83.9%) patients had varying expression of SOX9, of whom 51(45.4%) had overexpression. Univariate analysis demonstrated that the expression of SOX9 was significantly associated with Lauren classification (P<0.05), tumor invasion(P<0.01), lymph node metastasis(P<0.05), distant metastasis(P<0.05) and tumor stage(P<0.05), however there was no significant association between SOX9 expression and sex, age, histological type, histology differentiation or tumor size. Kaplan-Meier analysis showed that the 5-year survival rate of patients with SOX9 over-expression was significantly lower than that of patients with low expression(29.4% vs. 49.2%, P=0.031). Multivariate Cox regression analysis showed that histology differentiation(P=0.046), tumor invasion(P=0.001), and distant metastasis(P<0.01) were independent prognostic factors for gastric cancer, however the over-expression of SOX9 was not significant(P=0.948).</p><p><b>CONCLUSIONS</b>The expression SOX9 is associated with the growth, invasion, and metastasis of gastric cancer, as well as the prognosis. However, SOX9 expression is not an independent factor for the prognosis in patients with gastric cancer.</p>

RESUMO

Diabetes surgery is a new concept in recent years, which means controlling blood sugar or curing diabetes through some surgical methods. From the commencement of bariatric surgery in the 1950s to the discovery of the special function of decreasing blood sugar after these surgeries in 1970s, and then the fast developing of diabetes surgery in the past 30 years, now there seems be a different answer to the question that if we can cure diabetes. In this article, we review the historical evolution, surgical procedure, potential mechanism and outlook of diabetes surgery.

RESUMO

<p><b>OBJECTIVE</b>To study the clinical value of uncut Roux-en-Y esophagojejunostomy with distal jejunal pouch on behalf of the stomach (URYAJP) surgery in the digestive tract reconstruction after total gastrectomy.</p><p><b>METHODS</b>A retrospective analysis of radical resection of the whole stomach in 486 cases of gastric cancer patients, divided into the URYAJP group (n = 189), the P-loop Roux-en-Y behalf of the stomach surgery (PRY) group (n = 150) and pure Roux-en-Y reconstruction (RY) group (n = 147). Three groups were compared in patients with surgical reconstruction time, the occurrence of postoperative complications, the postoperative weight after 6, 12 and 24 months, the single meal food intake and prognostic nutritional index (PNI) and Visick points class situation after 12 and 24 months.</p><p><b>RESULTS</b>(1) The URYAJP group and RY group had no significant difference in digestive tract reconstruction time ((37 ± 6) minutes and (38 ± 6) minutes respectively), but PRY group was significantly prolonged ((47 ± 6) minutes, t = 7.52 and 6.54, P < 0.05). (2) In the comparison of the incidence of complications, URYAJP group has 2.1% rate of Roux stay syndrome (RSS) incidence, significantly less than PRY group (21.3%) and RY group (19.7%) (χ² = 14.84, P < 0.05). (3) In the comparison the postoperative nutritional status, URYAJP group clear asset, showing the degree of ((3.1 ± 1.0) kg) weight loss after 12 months (t = 25.03 and 22.99, P < 0.05). And after 12, 24 months, a single meal eating reached the preoperative level is 94.8% and 96.9% in URYAJP group, while PRY group and RY group is less than 50% (χ(2) = 61.10, 69.17, 65.17 and 73.29, P < 0.05). URYAJP Group reach the preoperative levels of PNI in 24 months after surgery, while PRY and RY group were still lower than per-operation (t = 106.97 and 100.37, P < 0.05). (4) The Visick points class I-II postoperative 12 and 24 months in URYAJP group were 92.7% and 93.8%, significantly better than group B and C (χ² = 10.63, 14.19, 10.10 and 10.74, P < 0.05).</p><p><b>CONCLUSIONS</b>URYAJP surgery give full play to maintain intestinal continuity, simple operation, and advantages of food storage bags, it can reduce the long-term postoperative complications, improve the nutritional status of patients and improve quality of life. It is worthy of promoting a way of gastrointestinal reconstruction.</p>

RESUMO

<p><b>BACKGROUND</b>Assessment of lymph node metastasis (LNM) is important in early gastric cancer (EGC) and affects treatment decisions. However, the relationship between clinicopathological characteristics and LNM in EGC remains unclear. This study therefore explored favorable predictors of LNM in EGC.</p><p><b>METHODS</b>A total of 716 specimens from gastric cancer patients who underwent curative gastrectomy between 1996 and 2003 at Zhejiang Provincial People's Hospital were reviewed. Forty-five cases were EGC, and clinicopathological characteristics such as gender, age, tumor size, location, gross type, differentiation, invasion depth, and vessel involvement were assessed to identify predictive factors for LNM and survival time.</p><p><b>RESULTS</b>The overall cumulative 5-year survival rate of EGC patients was 88.92%. Among these, 22.4% developed LNM, which was associated with a poor 5-year survival rate of only 72.7%. Patients with tumors larger than 2 cm in diameters, with depth of tumor invasion to the submucosa, and with positive lymphatic or nerve involvement were also inclined to have poorer survival performances. EGC limited to the mucosa but poorly differentiated also had a high risk for LNM. Multivariate analysis identified lymphatic invasion and tumor size as independent prognosis factors related to survival in EGC patients.</p><p><b>CONCLUSIONS</b>Careful planning is required in EGC patients at high risk of lymph node metastases. Endoscopic mucosal resection or endoscopic submucosal dissection and laparoscopic partial gastrectomy should be cautiously used in EGC, and curative gastrectomy including lymphatic dissection and postoperative adjuvant therapy might be considered to improve the prognosis.</p>

RESUMO

<p><b>OBJECTIVE</b>To compare the surgical outcomes between laparoscopic and open wedge resection for gastrointestinal stromal tumors of the stomach.</p><p><b>METHODS</b>Clinical data of 18 cases undergoing laparoscopic wedge resection from June 2000 to August 2009 at the Zhejiang Provincial People's Hospital were compared with 30 patients treated by open surgery. The perioperative parameters and prognosis data of the two groups were compared.</p><p><b>RESULTS</b>Compared to the open group, laparoscopic group was found with longer operative time, less blood loss, less requirement of postoperative analgesia, earlier resumption of oral intake, earlier return of first flatus, and shorter postoperative hospital stay(all P<0.05). There were no postoperative deaths in both groups. Postoperative complication rate was significantly lower in the laparoscopic group(5.5% vs. 33.3%, P<0.05). The postoperative recurrence rates were 11.8%(2/17) and 10.7%(3/28); the 5-year survival rates were 78% and 63%, respectively, and the difference was not statistically significant(P>0.05).</p><p><b>CONCLUSION</b>Laparoscopic wedge resection is a feasible treatment option for GISTs of the stomach.</p>

RESUMO

<p><b>OBJECTIVE</b>To evaluate the impact of reconstruction techniques after subtotal gastrectomy on postoperative glucose and insulin levels after oral glucose tolerance test (OGTT).</p><p><b>METHODS</b>Distal gastrectomy was performed in 38 Beagle dogs. Reconstruction techniques used included integral continual jejunal interposition (n=9), Billroth I( (n=6), Billroth II( (n=7), and isolated jejunal interposition (n=8). Eight controls were used. OGTT was conducted to examine the changes in glucose and insulin levels.</p><p><b>RESULTS</b>Compared to controls, glucose significantly increased in all the 4 operative groups and peaked at 60 min. Billroth II( was associated with the most significant increase. Insulin level significantly increased in all the experimental groups in response to food stimulus and peaked at 60 min. However, the increase of insulin in Billroth II( group was not as prominent as in other groups.</p><p><b>CONCLUSIONS</b>Fluctuation of blood glucose after gastrectomy may be mitigated and insulin elevated if duodenal passage is preserved. Continual jejunal interposition should be given priority when Billroth I( reconstruction is not feasible.</p>

RESUMO

<p><b>OBJECTIVE</b>To investigate the effect of early enteral nutrition (EEN) supplemented with glutamine on postoperative intestinal mucosal barrier function of patients with gastric carcinoma.</p><p><b>METHODS</b>Eighty patients with gastric carcinoma who underwent intraoperative peritoneal hyperthermic chemotherapy(IPHC) were randomized into two groups: EEN+glutamine (EEN+Gln) group(n=40) and EEN group(n=40). Intestinal mucosal barrier function was evaluated by serum diamine oxidase (DAO), ratio of lactulose to mannitol(L/M), endotoxin lipopolysaccharides(LPS), and tumor necrosis factor-α(TNF-α) at 1 day before operation, 1 day, 7 days, 12 days after operation. Time to first flatus and tolerance to EEN were recorded as well.</p><p><b>RESULTS</b>There were no significant differences in the two groups in demographics(all P>0.05). Two cases(5%) in the EEN+Gln group and 1 case (2.5%) in the EEN group could not tolerate well(P>0.05). On postoperative day 1, there were no differences in serum DAO, L/M ratio, LPS, TNF-α between the two groups (P>0.05). On postoperative day 7, all the parameters for mucosal barrier function were significantly lower in the EEN+Gln group. On postoperative day 12, the urinary L/M and DAO, LPS, and TNF-α were still significantly lower in the EEN+Gln group, however, urinary L/M was comparable between the two groups. There were no differences between the two groups in the time to first flatus (P>0.05).</p><p><b>CONCLUSION</b>The immunologic tolerance of enteral nutrition supplemented with glutamine is favorable, which provides protective effect on intestinal mucosal barrier in patients with gastric carcinoma undergoing IPHC.</p>

RESUMO

<p><b>BACKGROUND</b>Gastric cancer (GC) is the second leading cause of cancer mortality worldwide, and surgical resection is currently the only possible curative approach. Duodenal stump leakage is the most serious complication after radical gastrectomy, and optimal treatment is still lacking.</p><p><b>METHODS</b>We retrospectively reviewed 2034 cases of total or subtotal gastrectomy for GC from January 1995 to December 2009, including 465 cases of duodenal stump closure using purse-string suture (group A), 835 cases of duodenal stump treated with linear cutting stapler and seromuscular layer suture (group B), and 734 cases of duodenal stump closure using full-thickness and seromuscular layer suture (group C). We evaluated the surgical cost, operative time for duodenal stump closure, short-term postoperative complications, perioperative blood loss, and postoperative recovery.</p><p><b>RESULTS</b>There was no perioperative mortality in any group. Ninety-four postoperative (within 1 month) complications occurred: 18 abdominal bleeding, 14 anastomotic leakage, 15 abdominal infection, 36 wound infection, and 11 duodenal stump leakage. There was no significant difference among the groups in intra-abdominal hemorrhage, anastomotic leakage, abdominal infection and wound infection. No postoperative duodenal stump leakage occurred in group A, which had a significant difference compared with groups B and C (6 cases in group B and 5 cases in group C suffered duodenal stump leakage. P < 0.01). The surgical cost in groups A and C was significantly lower than in group B (P < 0.01), with no significant difference between groups A and C. The processing time for duodenal stump closure in groups A and B was significantly shorter than in group C (P < 0.01), with no significant difference between groups A and B. There was no significant difference in blood loss and postoperative recovery among the groups.</p><p><b>CONCLUSIONS</b>Duodenal stump closure using purse-string suture seems to be a promising approach with shorter operative time, and lower cost and incidence of duodenal stump leakage in radical gastrectomy.</p>

RESUMO

<p><b>OBJECTIVE</b>To evaluate nutritional status, myoelectrical activity, and gastrointestinal tract emptying capacity after integral continuous jejunal interposition following subtotal gastrectomy.</p><p><b>METHODS</b>According to different re-construction techniques, 30 Beagle dogs were divided into four groups after subtotal distal gastrectomy: group 1(n=9, integral continuous jejunal interposition), group 2(n=6, Billroth I(), group 3(n=7, Billroth II(), group 4(n=8, isolated jejunal interposition). Blood cell counts, liver function, myoelectrical activity and the rate of gastrointestinal tract emptying were compared among the four groups.</p><p><b>RESULTS</b>At week 12 after operation, the body weight in group 1 [(9.65±1.54) kg] was significantly higher than that in group 2[(9.25±1.76)kg], group 3[(9.31±1.54)kg] and group 4[(7.77±1.46)kg]. At week 4, the prognostic nutritional index in group 1(2671.9±49.9) was significantly higher than that in group 3(2555.9±54.7) and group 4(2440.9±54.3), but similar to that in group 2(2791.8±54.3). At week 6, the fasting and postprandial frequency of jejunal pacesetter potentials in group 1 were higher than those in group 3 and group 4(P<0.05) but comparable with those in group 2. The emptying rate of food in the four groups were 95.4%, 91.3%, 93.1% and 94.2%, respectively and there were no significant differences(P>0.05). However, as compared with group 2 and group 3, group 1 had longer operative time and later regular diet resumption, more severe abdominal adhesion(P<0.05).</p><p><b>CONCLUSION</b>Continuous jejunal interposition should be considered when Billroth I( is not feasible after subtotal gastrectomy.</p>

RESUMO

<p><b>OBJECTIVE</b>To investigate the association between the morphological features of biopsy-diagnosed high grade intraepithelial neoplasia in the gastric mucosa and the postoperative pathology.</p><p><b>METHODS</b>Fifty-one patients with biopsy-diagnosed high grade intraepithelial neoplasia in the gastric mucosa were retrospectively analyzed. Thirty-three patients underwent surgery. The morphology of lesions under endoscopy and histopathological findings of the surgical specimens were investigated.</p><p><b>RESULTS</b>Of the 51 patients, 43 had superficial lesions similar to early gastric cancer under endoscopy, 8 were similar to advanced carcinoma. In the 33 surgical cases, high grade intraepithelial neoplasia of gastric mucosa was confirmed on postoperative pathological examination in 13 (39.4%) patients, adenocarcinoma was identified in the remaining 20 patients (60.6%), including 14 early gastric cancers and 6 advanced carcinomas. Thirteen cases with high grade intraepithelial neoplasia confirmed postoperatively were superficial elevated or flat lesions less than 20 mm.</p><p><b>CONCLUSIONS</b>Patients with biopsy-diagnosed high grade intraepithelial neoplasia in the gastric mucosa have a high risk of cancer. Thus aggressive follow-up and appropriate surgical interventions are recommended to avoid misdiagnosis.</p>

RESUMO

<p><b>OBJECTIVE</b>To summarize the experience in nutritional support for the management of duodenocutaneous fistula.</p><p><b>METHODS</b>Data of 32 patients with duodenocutaneous fistula in Zhejiang provincial people's hospital from January 1999 to December 2009 were analyzed retrospectively.</p><p><b>RESULTS</b>The mean duration of nutritional support was 35.6 days (range, 8-82 days). Eight received total parenteral nutrition, 2 total enteral nutrition, and 22 parenteral nutrition combined with enteral nutrition respectively. Succus entericus reinfusion with enteral nutrition was used in 11 cases, glutamine-enriched nutritional support in 28 cases, somatostatin in 12 cases. In these patients, the healing rate was 75.0% after conservative treatment. In the 8 patients who underwent surgery, 6 were cured and 2 died (due to severe abdominal infection and multiple organ failure). A total of 30 patients had the fistulas cured and discharged.</p><p><b>CONCLUSIONS</b>Parenteral nutrition combined with enteral nutrition, succus entericus reinfusion combined with enteral nutrition, glutamine-enriched nutritional support and somatostatin are important factors for the healing of duodenocutaneous fistulas.</p>

RESUMO

<p><b>OBJECTIVE</b>To investigate the clinicopathological characteristics, surgical treatment and prognosis of gastrointestinal stromal tumors(GIST).</p><p><b>METHODS</b>The clinicopathological data of 84 patients with GIST undergone resection between April 1997 and June 2008 were analyzed retrospectively, and the prognosis was evaluated.</p><p><b>RESULTS</b>Out of 84 cases, 42 tumors located in stomach, 24 in small intestine, 18 in other sites. Tumor sizes ranged from 0.5 to 25 cm(average 5.6 cm). Positive rate of CD117 expression determined by immunohistochemical methods was 96.4%. Seventy-nine cases underwent complete tumor resection, while 5 cases received palliative resection or biopsy. Seventy-eight patients were followed up and their 1-, 3-, 5-year survival rates were 92.0%, 79.2%, 72.0% respectively. The Fletcher's classification of malignancy risk groups for GIST was related to the survival rates(P=0.001). The differences of survival rate among very low risk group, low risk group and high-risk group were significant(P=0.003, P=0.000).</p><p><b>CONCLUSIONS</b>Complete tumor resection in the initial operation of GIST should be emphasized. The Fletcher's classification of malignancy risk groups for GIST is related to the survival rate. Extended surgical resection is required for GIST of higher malignancy risk.</p>

RESUMO

<p><b>OBJECTIVE</b>To investigate the effects and prognosis of surgical treatment in primary gastrointestinal stromal tumors (GIST).</p><p><b>METHODS</b>The clinicopathological data of 73 patients with primary GIST underwent operation from April 1997 to December 2007 was retrospectively analyzed, and the prognosis was evaluated too.</p><p><b>RESULTS</b>Among the 73 cases, 68 cases received complete tumor resection, among which 12 cases underwent laparoscopic operation; while palliative resection and biopsy only were carried out in the other 5 cases. There was significant difference in survival rate between the two groups (P = 0.000). The 1-, 3-, 5-year survival rates of the 66 cases had been followed up was 91.0%, 78.2% and 74.1%, respectively. The malignancy risk grades of GIST was related to the survival rates on statistical analysis (P = 0.002). Significant differences were found in the survival rates between the patients with very low grade, low grade and high grade malignancy tumors (P = 0.012, 0.002).</p><p><b>CONCLUSIONS</b>Complete tumor resection should be emphasized in primary GIST, and more attention should be paid to the initial surgical treatment. Extended surgical resection is required for tumors of higher malignancy risk. The indications of laparoscopic surgery in GIST should be selected with caution for tumor complete resection.</p>
