Open versus laparoscopic right hemicolectomy in the elderly population

AIM:To compare short term outcomes of elective laparoscopic and open right hemicolectomy(RH) in an elderly population.METHODS:All patients over the age of 70 undergoing elective RH at Ninewells Hospital and Perth Royal Infirmary between January 2006 and May 2011 were included in our analysis.Operative details,hospital length of stay,morbidity and mortality was collected by way of proforma from a dedicated prospective database.An extracorporeal anastomosis was performed routinely in the laparoscopic group.The primary endpoints for analysis were morbidity and mortality.Our secondary endpoints were operative duration,length of hospital stay and discharge destination.RESULTS:Two hundred and six patients were included in our analysis.One hundred and twenty-five patients underwent an open resection and 81 patients had a laparoscopic resection.The mean operating time was significantly longer in the laparoscopic group(139 ± 36 min vs 197 ± 53 min,P = 0.001).The mean length of hospital stay was similar in both groups(11.2 ± 7.8 d vs 9.6 ± 10.7 d,P = 0.28).The incidence of postoperative morbidities was 27% in the open group and 38% in the laparoscopic group(P = 0.12).Overall inhospital mortality was 0.8% in open procedures vs 1% in laparoscopic.CONCLUSION:Laparoscopic RH was associated with a significantly longer operative time compared to open RH.In our study,laparoscopic RH was not associated with reduced post-operative morbidity or significantly shorter length of hospital stay.     

Results of the open surgery after endoscopic basket impaction during ERCP procedure

AIM:To report the results of open surgery for patients with basket impaction during endoscopic retrograde cholangiopancreatography(ERCP) procedure.METHODS: Basket impaction of either classical Dormia basket or mechanical lithotripter basket with an entrapped stone occurred in six patients.These patients were immediately operated for removal of stone(s) and impacted basket.The postoperative course,length of hospital stay,diameter of the stone,complication and the surgical procedure of the patients were reported retrospectively.RESULTS: Six patients(M/F,0/6) were operated due to impacted basket during ERCP procedure.The mean age of the patients was 64.33 ± 14.41 years.In all cases the surgery was performed immediately after the failed ERCP procedure by making a rightsubcostal incision.The baskets containing the stone were removed through longitudinal choledochotomy with the stone.The choledochotomy incisions were closed by primary closure in four patients and T tube placement in two patients.All patients were also performed cholecystectomy additionally since they had cholelithiasis.In patients with T-tube placement it was removed on the 13 th day after a normal T-tube cholangiogram.The patients remained stable at postoperative period and discharged without any complication at median 7 d.CONCLUSION: Open surgical procedures can be applied in patients with basket impaction during ERCP procedure in selected cases.     

Polymyxin B hemoperfusion as a feasible therapy after source control in abdominal septic shock

BACKGROUND Polymyxin B hemoperfusion(PMX-HP) has been used as a treatment for intraabdominal septic shock by absorbing and removing endotoxins of gram-negative bacilli.AIM To investigate the clinical efficacy of PMX-HP in patients with gram-negative septic shock who underwent abdominal surgery.METHODS From January 2012 to December 2018, patients who had septic shock secondary to peritonitis were enrolled. They were classified into PMX-HP treated and control groups based on postopreative intervention using PMX-HP. The clinical outcomes were compared using 1:1 propensity score matching methods to balance the overall distribution between the two groups.RESULTS After propensity score matching, 40 patients were analyzed(20 patients in the PMX group and 20 patients in the control group). The scores of total Sequential Organ Failure Assessment(SOFA) score, renal SOFA and coagulation SOFA were significantly improved in the PMX group but not in the control group.(from 11.2± 5.8 to 4.7 ± 3.5 in PMX group vs 10.0 ± 4.0 to 8.7 ± 7.3 in control group, P = 0.047 from 2.6 ± 1.0 to 0.7 ± 1.0 in PMX group vs 2.6 ± 1.5 to 2.8 ± 1.6 in control group, P= 0.000, from 1.6 ± 1.5 to 1.3 ± 1.3 in PMX group vs 1.2 ± 1.2 to 2.8 ± 1.8 in control group, P = 0.014, respectively). Further, the length of intensive care unit(ICU)stay was significantly shorter in PMX group. However, no statistically significant difference was found in ICU mortality(50% in PMX group vs 50% in control group).CONCLUSION PMX-HP is a feasible adjunct treatment for peritonitis in ICU patients with peritonitis for improved organ impairment and to stabilize hemodynamics. It would be helpful to enhance clinical outcomes especially in patients with complete elimination of the source of gram-negative bacilli infection by surgical procedure accompanied with conventional treatment of sepsis.

胰管结石的分型和治疗

Objective To explore the classification and surgical management of pancreatic duct stones.Methods The clinical data of 54 patients with pancreatic duct stones who were admitted to the People's Hospital of Hunan Province from June 1994 to November 2009 were retrospectively analyzed. Stones were found in the head of the pancreas (type Ⅰ ) in 31 patients, in the body and tail of the pancreas (type Ⅱ ) in 7 patients, and in all the pancreas (type Ⅲ ) in 16 patients. According to the types of the pancreatic duct stones, ten patients (6 with type Ⅰ , two with type Ⅱ and two with type Ⅲ pancreatic duct stones) received opening of the main pancreatic duct + pancreaticojejunostomy or pancreaticogastrostomy ( group A). Twenty-four patients ( 16 with type Ⅰ and eight with type Ⅲ pancreatic duct stones) received pancreaticoduodenectomy (group B). Fifteen patients (nine with type Ⅰ and six with type Ⅱ pancreatic duct stones) received subtotal resection of pancreatic head preserving duodenum (group C). Five patients with type Ⅱ pancreatic duct stones received resection of the body and tail of the pancreas and the spleen (group D). All data were analyzed using the t test. Results The mean operation time, blood loss, length of postoperative stay and hospital charges of group A were (2.2 ± 1.2)hours,( 127 ±24)ml,( 11.4 ±4.3) days and (3.24 ± 1.15 ) × 104 yuan, respectively. Five out of nine patients who were followed up had stone recurrence. The mean operation time, blood loss, length of postoperative stay and hospital charges of group B were (7.6 ± 1.1 ) hours, (409 ± 37 ) ml, ( 18.9 ± 2.5 ) days and (7.93 ± 1.35 ) × 104 yuan, respectively.No stone recurrence was detected in the 21 patients who were followed up. The mean operation time, blood loss,length of postoperative stay and hospital charges of group C were (4. 1 ± 0.7 ) hours, ( 156 ± 63 ) ml, ( 10.3 ±2.1 )days and (4. 12 ± 1.22) × 104 yuan, respectively. No stone recurrence was detected in the 15 patients who were followed up. The mean operation time, blood loss, length of postoperative stay and hospital charges of group D were (3.3 ± 1.4) hours, ( 185 ± 36 ) ml, ( 9.3 ± 2.0) days and ( 3.22 ± 1.05 ) × 104 yuan, respectively. No complication was detected after the operation, and no stone recurrence was detected in the three patients who were followed up. There were significant differences in the mean operation time, blood loss, length of postoperative stay and hospital charges between patients with type Ⅰ and Ⅲ pancreatic duct stones who received pancreaticoduodenectomy and subtotal resection of pancreatic head preserving duodenum (t = 12. 143, 14. 099, 11. 550, 9. 103,P < 0.05 ). Conclusions Classification of the pancreatic duct stones is important for choosing the proper surgical procedure. Subtotal resection of pancreatic head preserving duodenum is ideal for the treatment of patients with type Ⅰ or Ⅱ pancreatic duct stones.     

Short-term efficacy of laparoscopy-assisted vs open radical gastrectomy in gastric cancer

AIM:To investigate the short-term benefits of laparoscopic radical gastrectomy(LARG)and open radical gastrectomy(ORG)in patients with gastric cancer.METHODS:A total of 400 patients with gastric cancer aged≤65 years who were treated at General Hospital of Lanzhou Military Region were enrolled.Among these,200 patients underwent LARG between October2008 and August 2012(LARG group);and 200 patients underwent ORG between March 2000 and September2008(ORG group).The short-term therapeutic benefits between the two groups were analyzed.RESULTS:The LARG procedure offered significantly better benefits to the patients compared to the ORG procedure,including less intraoperative blood loss(103.1±19.5 mL vs 163.0±32.9 mL,P0.0001),shorter postoperative hospital stay(6.8±1.2 d vs 9.5±1.6 d,P0.0001),less frequent occurrence of postoperative complications(6.5%vs 13.5%,P=0.02),shorter time to mobilization(1.0±0.3 vs 3.3±0.4 d,P0.0001),shorter time to bowel opening(3.3±0.7 d vs 4.5±0.7 d,P0.0001),and shorter time to normal diet(3.0±0.4 vs d 3.8±0.5 d,P0.0001).However,LARG required a longer time to complete than the ORG procedure(192.3±20.9 min vs 180.0±26.9 min,P0.0001).CONCLUSION:Compared to ORG,LARG is safer,more effective,and less invasive for treating gastric cancer,with better short-term efficacy.     

Primary colon resection or Hartmann's procedure in malignant left-sided large bowel obstruction? The use of stents as a bridge to surgery

There is still significant debate regarding the best surgical treatment for malignant left-sided large bowel obstruction.Primary resection and anastomosis offers the advantages of a definite procedure without need for further surgery.Its main disadvantages are related to the increased technical challenge and to the potential higher risk of anastomotic leakage that occurs in the emergency setting.Primary resection with end colostomy(Hartmann’s procedure) is considered the safer option.Tan et al compared in a systematic review and meta-analysis the use of self-expanding metallic stents(SEMS) as a bridge to surgery vs emergency surgery in the management of acute malignant left-sided large bowel obstruction.The authors concluded that the technical and clinical success rates for stenting were lower than expected.SEMS was associated with a high incidence of clinical and silent perforation.Stenting instead of loop colostomy can be recommended only if the appropriate expertise is available in the hospital.The goal of stenting,a decrease of the stoma rate,may be advocated only if the complication rates of stenting are lower than those of stoma creation in the emergency situation.Until now,this was not demonstrated in a prospective randomized trial.     

Comparative study of anterolateral approach versus posterior approach for total hip replacement in the treatment of femoral neck fractures in elderly patients

Objective： To compare the clinical outcome of anterolateral minimally invasive approach versus conventional posterior approach for total hip replacement against femoral neck fractures in elderly patients.
Methods： The retrospective study was carried out on 42 patients who suffered from displaced femoral neck fractures （19 cases of Garden type Ⅲ, 23 cases of Garden type Ⅳ） treated by total hip replacement via anterolateral minimally invasive approach or conventional posterior approach by the same experienced surgeon. The average age of the patients was 78.1 years （range： 65-89 years）. They were divided into anterolateral mini-invasive group （22 cases） and posterior group （20 cases）. The mean time of follow-up was 13 months （range： 6-36 months）. The anterolateral approach described by Hardinge goes through between anterior 1/3 and posterior 2/3 of the gluteus medius muscle, reaching the femoral neck from anterior capsule. The traditional posterior approach described by Moore （Southern incision） goes through the insertions of short external rotation muscles, reaching the femoral neck from posterior capsule. The related variables under observation were length of incision, operation time, postoperative limp, length of hospital stay and bed stay and dislolcation rate.
Results： The length of the skin incision varied between 7 cm and 12 cm with the anterolateral minimally invasive technique, compared to 15-22 cm in the conventional procedure. It took less time （average 15 minutes） to complete the anterolateral minimally invasive approach （72 15 min）, compared with the conventional approach （87 min ±10 min）. The average Harris hip score was 91.23±10.20 in anterolateral approach, 90.03±11.05 in the posterior approach. The average length of hospital stay for patients with the anterolateral approach was （6.4±2.2） days （range： 4-9 days）, while that in posterior approach was （9.2 ±3.1） days （range： 6-13 days）. The average length of bed stay was （3.4±1.1） days （range： 2-5 days） in anterolateral group and （6.2±2.8） days （range： 3-10 days） in posterior group. No patients in anterolateral group experienced dislocation. One （5%） hip in posterior approach had dislocation. Conclusions： Anterolateral mini-invasive approach can decrease trauma, operation time, length of hospital stay and bed stay and rehabilitation time. The stability and minimal muscular damage permit the acceleration of postoperative rehabilitation, which can subsequently reduce the perioperative risk in the treatment of femoral neck fractures in the elderly undergoing total hip replacement.     

Transcutaneous electroacupuncture alleviates postoperative ileus after gastrectomy: A randomized clinical trial

AIM To investigate the efficacy and safety of transcutaneouselectroacupuncture(TEA) to alleviate postoperative ileus(POI) after gastrectomy.METHODS From April 2014 to February 2017, 63 gastric cancer patients were recruited from the Second Affiliated Hospital of Zhejiang University School of Medicine, Hangzhou, China. After gastrectomy, the patients were randomly allocated to the TEA(n = 33) or control(n = 30) group. The patients in the TEA group received 1 h TEA on Neiguan(ST36) and Zusanli(PC6) twice daily in the morning and afternoon until they passed flatus. The main outcomes were hours to the first flatus or bowel movement, time to nasogastric tube removal, time to liquid and semi-liquid diet, and hospital stay. The secondary outcomes included postoperative symptom assessment and complications.RESULTS Time to first flatus in the TEA group was significantly shorter than in the control group(73.19 ± 15.61 vs 82.82 ± 20.25 h, P = 0.038), especially for open gastrectomy(76.53 ± 14.29 vs 87.23 ± 20.75 h, P = 0.048). Bowel sounds on day 2 in the TEA group were significantly greater than in the control group(2.30 ± 2.61/min vs 1.05 ± 1.26/min, P = 0.017). Time to nasogastric tube removal in the TEA group was earlier than in the control group(4.22 ± 1.01 vs 4.97 ± 1.67 d, P = 0.049), as well as the time to liquid diet(5.0 ± 1.34 vs 5.83 ± 2.10 d, P = 0.039). Hospital stay in the TEA group was significantly shorter than in the control group(8.06 ± 1.75 vs 9.40 ± 3.09 d, P = 0.041). No significant differences in postoperative symptom assessment and complications were found between the groups. There were no severe adverse events related to TEA.CONCLUSION TEA accelerated bowel movements and alleviated POI after open gastrectomy and shortened hospital stay.     

代谢综合征与胃癌患者术后短期疗效的关系研究

Objective To investigate the incidence of metabolic syndrome (MS) in patients with gastric cancer, and to explore the relationship between MS and the tumor site and the influence of MS on surgical procedure and short-term outcomes of patients with gastric cancer. Methods The clinical data of 639 patients with gastric cancer who were admitted to the Affiliated Hospital of Qingdao University from January 2006 to June 2008 were retrospectively analyzed. Patients with MS were in the MS group ( n= 64) and those without MS were in the control group ( n = 575 ). The surgical and postoperative complications were reviewed and the tumor site, intraoperative conditions and short-term outcomes between the two groups were analyzed. All data were analyzed using the chi-square test or t test. Results The incidence of MS in patients with gastric cancer was 10.0% (64/639).The incidence of MS in female patients was 14.4% (27/188), which was significantly higher than 8.2% (37/451)of male patients ( χ2= 6.265, P < 0.05). The operation time of the MS group was ( 185 ± 133 ) minutes, which was significantly longer than ( 168 ± 50) minutes of the control group ( t = 2. 126, P < 0. 05 ). The number of lymph nodes dissected in the MS group was 18 ± 11, which was significantly lower than 21 ± 11 of the control group ( t = 2. 125, P < 0.05 ). The postoperative period of fever of the MS group was (3.0 ± 1.4) days, which was significantly longer than (2.5 ± 1.4) days of the control group (t = 2. 433, P < 0.05 ). The incidence of postoperative complications of the MS group was 31.3% (20/64), which was significantly higher than 14.3% (82/575) of the control group ( χ2 = 12.291, P < 0.05 ). The length of hospital stay of the MS group was ( 19 ± 11 ) days,which was significantly longer than ( 16±11 ) days of the control group ( t = 2. 141, P< 0.05 ). The mortalities of MS group and control group were 0 and 0. 5% (3/575), respectively, with no significant difference ( χ2 = 0.000,P >0.05). Condusions A low prevalence of MS is found in patients with gastric cancer. However, patients with gastric cancer complicated with MS may present with prolonged surgical procedure, reduced amount of lymph nodes dissected and increased incidence of postoperative complications, hospital stay and costs. Perioperative management of patients with gastric cancer complicated with MS should be paid more attention.     

Implications of the presence of an aberrant right hepatic artery in patients undergoing pancreaticoduodenectomy

AIM:To analyze the differences in outcomes and the clinical impact following pancreatoduodenectomy(PD)in patients with and without aberrant right hepatic artery(aRHA).METHODS:All patients undergoing PD between January 2008 and December 2012 were divided into two groups,one with aRHA and the other without.These groups were compared to identify differences in the intraoperative variables,the oncological clearance and the postoperative morbidity,mortality and hospital stay.RESULTS:A total of 225 patients underwent PD,of which 43(19.1%)patients were found to have eitheraccessory or replaced right hepatic arteries(aRHA group).The aRHA was preserved in 79%of the patients.There was no significant difference in the intraoperative blood loss but operative time was prolonged,reflecting the complexity of the procedure[420±44(240-540)min vs 480±45(300-600)min,P0.05)].There were no differences in the incidence of postoperative complications(pancreatic leak,pancreatic fistula,delayed gastric emptying and mortality)and hospital stay.Oncological clearance in the form of positive resection margins[13(7.1%)vs 3(6.9%)]and lymph node yield were also similar in the two groups.CONCLUSION:An aRHA is found in approximately one fifth of patients undergoing PD.Preservation is technically possible in most patients and can increase the operative complexity but does not negatively affect the safety or oncological outcomes of the procedure.     

Single-port laparoscopic cholecystectomy vs standard laparoscopic cholecystectomy: A non-randomized,age-matched single center trial

AIM: To compare the safety of single-port laparoscopic cholecystectomies with standard four-port cholecystectomies.METHODS: Between January 2011 and December 2012 datas were gathered from 100 consecutive patients who received a single-port cholecystectomy. Patient baseline characteristics of all 100 single-port cholecystectomies were collected(body mass index, age, etc.) in a database. This group was compared with 100 age-matched patients who underwent a conventional laparoscopic cholecystectomy in the same period. Retrospectively, per- and postoperative data were added. The two groups were compared to each other using independent t-tests and χ2-tests, P values below 0.05 were considered significantly different.RESULTS: No differences were found between both groups regarding baseline characteristics. Operating time was significantly shorter in the total single-port group(42 min vs 62 min, P 0.05); in procedures performed by surgeons the same trend was seen(45 min vs 59 min, P 0.05). Peroperative complications between both groups were equal(3 in the single-port group vs 5 in the multiport group; P = 0.42). Although not significant less postoperative complications were seen in the single-port group compared with the multiport group(3 vs 9; P = 0.07). No statistically significant differences were found between both groupswith regard to length of hospital stay, readmissions and mortality. CONCLUSION: Single-port laparoscopic cholecystectomy has the potential to be a safe technique with a low complication rate, short in-hospital stay and comparable operating time. Single-port cholecystectomy provides the patient an almost non-visible scar while preserving optimal quality of surgery. Further prospective studies are needed to prove the safety of the single-port technique.     

Results of single stage exchange arthroplasty with retention of well fixed cement-less femoral component in management of infected total hip arthroplasty

AIM To investigate success of one stage exchange with retention of fixed acetabular cup.METHODS Fifteen patients treated by single stage acetabular component exchange with retention of well-fixed femoral component in infected total hip arthroplasty(THA)were retrospectively reviewed.Inclusion criteria were patients with painful chronic infected total hip.The patient had radiologically well fixed femoral components,absence of major soft tissue or bone defect compromising,and infecting organism was not poly or virulent microorganism.The organisms were identified preoperatively in14 patients(93.3%),coagulase negative Staphylococcus was the infecting organism in 8 patients(53.3%).RESULTS Mean age of the patients at surgery was 58.93(±10.67)years.Mean follow-up was 102.8 mo(36-217 mo,SD56.4).Fourteen patients had no recurrence of the infection;one hip(6.7%)was revised for management of infection.Statistical analysis using Kaplan Meier curve showed 93.3%survival rate.One failure in our series;the infection recurred after 14 mo,the patient was treated successfully with surgical intervention by irrigation,and debridement and liner exchange.Two complications:The first patient had recurrent hip dislocation 12 years following the definitive procedure,which was managed by revision THA with abductor reconstruction and constrained acetabular liner;the second complication was aseptic loosening of the acetabular component 2years following the definitive procedure.CONCLUSION Successful in management of infected THA when following criteria are met;well-fixed stem,no draining sinuses,non-immune compromised patients,and infection with sensitive organisms.     

Laparoscopic approach in complicated diverticular disease

AIM: To analyze the results of laparoscopic colectomy in complicated diverticular disease.METHODS: This was a retrospective cohort study conducted at an academic teaching hospital. Data were collected from a database established earlier, which comprise of all patients who underwent laparoscopic colectomy for diverticular disease between 2000 and 2013. The series was divided into two groups that were compared: Patients with complicated disease(abscess, perforation, fistula, or stenosis)(G1) and patients undergoing surgery for recurrent diverticulitis(G2). Recurrent diverticulitis was defined as two or more episodes of diverticulitis regardless of patient age. Data regarding patient demographics, comorbidities, prior abdominal operations, history of acute diverticulitis, classification of acute diverticulitis at index admission and intra and postoperative variables were extracted. Univariate analysis was performed in both groups.RESULTS: Two hundred and sixty patients were included: 28%(72 patients) belonged to G1 and 72%(188 patients) to G2. The mean age was 57(27-89) years. The average number of episodes of diverticulitis before surgery was 2.1(r 0-10); 43 patients had no previous inflammatory pathology. There were significant differences between the two groups with respect to conversion rate and hospital stay(G1 18% vs G2 3.2%, P = 0.001; G1: 4.7 d vs G2 3.3 d, P < 0.001). The anastomotic dehiscence rate was 2.3%, with no statistical difference between the groups(G1 2.7% vs G2 2.1%, P = 0.5). There were no differences in demographic data(body mass index, American Society of Anesthesiology and previous abdominal surgery), operative time and intraoperative and postoperative complications between the groups. The mortality rate was 0.38%(1 patient), represented by a death secondary to septic shock in G2.CONCLUSION: The results support that the laparoscopic approach in any kind of complicated diverticular disease can be performed with low morbidity and acceptable conversion rates when compared with patients undergoing laparoscopic surgery for recurrent diverticulitis.

It can be selected as an alternative techniques and the appropriate age for this procedure is 10-16 years.     

Five-year outcomes of laparoscopic sleeve gastrectomy as a primary procedure for morbid obesity:A prospective study

AIM To prospectively evaluate the postoperative morbimortality and weight loss evolution of patients who underwent a laparoscopic sleeve gastrectomy(LSG) as a primary bariatric procedure during 5 years of follow-up. METHODS Since 2006,data from patients undergoing a highly restrictive primary LSG have been prospectively registered in a database and analysed. Preoperative co-morbid conditions,operating time,hospital stay,early and late complications rate and evolution of weight loss after 5 years of follow-up were analysed.RESULTS A total of 156 patients were included,74.3% of whom were women. The mean age was 43.2 ± 13.1 years and the mean body mass index(BMI) was 41.5 ± 7.9 kg/m~2. Seventy patients(44.8%) presented a BMI under 40 kg/m~2. The mortality rate was 0%. The leakage rate was 1.2%,and the total 30-d morbidity rate was 5.1%(8/156). With a mean follow-up of 32.7 ± 28.5(range 6-112) mo,the mean percent of excess of weight loss(%EWL) was 82.0 ± 18.8 at 1 year,76.7 ± 21.3 at 3 years and 60.3 ± 28.9 at 5 years. The mean percent of excess of BMI loss(%EBMIL) was 94.9 ± 22.4 at 1 year,89.4 ± 27.4 at 3 years and 74.8 ± 29.4 at 5 years. Patients with preoperative BMI less than 40 kg/m~2 achieved greaterweight loss than did the overall study population. Diabetes remitted in 75% of the patients and HTA improved in 71.7%. CPAP masks were withdrawn in all patients with obstructive sleep apnoea.CONCLUSION LSG built with a narrow 34 F bougie and starting 3 cm from the pylorus proved to be safe and highly effective in terms of weight loss as a stand-alone procedure,particularly in patients with a preoperative BMI lower than 40 kg/m~2.

快速康复外科在结直肠癌择期手术中的应用效果

Objective To investigate the clinical application of fast track surgery in patients undergoing elective colorectal carcinoma surgery. Methods Seventy patients with colorectal carcinoma requiring colorectal resection were randomized into two groups: fast-track group (35 cases) and conventional care group (35 cases). Results Sixty-two patients finished the study, 32 cases in fast-track group and 30 cases in conventional care group. The median and average time to the first passage of flatus (2±1 vs. 4±2, P<0.01), the first passage of stool (3.8±1.6 vs. 6.4±2.5, P=0.0007), resumption of normal diet [(4±2) vs. (8.2±2.2), P<0.01] and the length of postoperative stay (6±1 days vs. 11.7±3.8 days, P<0.01) were much shorter in the fast-track group than in the conventional care group. The preoperative incidence of thirst (2/32 vs. 23/30, P<0.01), hunger (5/32 vs. 20/30, P<0.01) and postoperative infectious complications (2/32 vs. 8/30, P=0.04) were much lower in the fast-track group than in the conventional care group. Conclusion Fast track surgery in patients undergoing elective colorectal resection was safe and effective.

Objective To investigate the clinical application of fast track surgery in patients undergoing elective colorectal carcinoma surgery. Methods Seventy patients with colorectal carcinoma requiring colorectal resection were randomized into two groups: fast-track group (35 cases) and conventional care group (35 cases). Results Sixty-two patients finished the study, 32 cases in fast-track group and 30 cases in conventional care group. The median and average time to the first passage of flatus (2±1 vs. 4±2, P<0.01), the first passage of stool (3.8±1.6 vs. 6.4±2.5, P=0.0007), resumption of normal diet [(4±2) vs. (8.2±2.2), P<0.01] and the length of postoperative stay (6±1 days vs. 11.7±3.8 days, P<0.01) were much shorter in the fast-track group than in the conventional care group. The preoperative incidence of thirst (2/32 vs. 23/30, P<0.01), hunger (5/32 vs. 20/30, P<0.01) and postoperative infectious complications (2/32 vs. 8/30, P=0.04) were much lower in the fast-track group than in the conventional care group.
