ABSTRACT
Objective:To analyze the short-term effects of prophylactic intraperitoneal hyperthermic chemotherapy(HIPEC)on elderly patients diagnosed with gastric cancer.Methods:The study enrolled patients with gastric cancer who underwent curative gastrectomy combined with postoperative HIPEC at Beijing Hospital between January 2017 and September 2022.The patients were divided into two groups based on age: young patients(age <65 years, n=45)and elderly patients(age≥65 years, n=32). The study evaluated the safety of HIPEC prophylactic application in elderly patients with gastric cancer by comparing their clinicopathological data, postoperative recovery, complications, and laboratory tests with those of another group of patients.Results:The study found that the elderly patients had a higher rate of comorbidities and higher ASA scores compared to the younger patients.Additionally, the elderly patients received HIPEC treatment less frequently than the younger patients( P=0.030). The proportion of young patients receiving one, two, and three times of HIPEC treatment was 8.9%, 57.8%, and 33.3%, respectively, while the proportion of elderly patients receiving the same was 28.1%, 59.4%, and 12.5%, respectively.The study found no significant differences in pathological characteristics between the two groups, including tumor stage, type, location, and differentiation degree.Additionally, there was no difference in the proportion of laparoscopic gastrectomy, type of resection, combined resection, duration of the operation, and intraoperative blood loss between elderly and young patients.The rate of complications between the two groups was also not significantly different(20.0% vs.21.9%; P=0.100). The mean duration of hospitalization after radical gastrectomy was 14.0 days in the young group and 15.5 days in the elderly group, respectively( P=0.480). Conclusions:Elderly patients with gastric cancer treated with radical gastrectomy combined with HIPEC did not experience increased postoperative complications or hospital stay compared to young patients, suggesting that prophylactic HIPEC was safe and feasible for elderly patients with locally advanced gastric cancer, as evidenced by favorable postoperative recovery and laboratory tests.
ABSTRACT
Objective:To evaluate the short-term efficacy of left colonic artery preservation in laparoscopic-assisted radical resection in elderly patients with rectal cancer.Methods:168 patients aged 65 and over who had undergonelaparoscopic-assisted radical resection of rectal cancer in the gastrointestinal surgery department of Beijing Hospital from December 2017 to December 2020 were retrospectively analyzed.According to different surgical methods, they were divided into the observation group with 90 subjects(the LCA group)and the control group with 78 subjects(the non-LCA group).Basic data, intraoperative, postoperative and clinicopathological data of the two groups were compared and analyzed.Results:There were no statistically significant differences between the two groups in operative time[(172.3±35.5)min vs.(155.5±28.7)min, t=2.182, P=0.103], intraoperative blood loss[(72.6±22.5)ml vs.(67.3±18.4)ml, t=1.473, P=0.128], number of group 253 lymph nodes dissected[(3.8±1.5) vs.(4.2±1.6), t=0.785, P=0.221], and total number of lymph nodes dissected[(14.1±4.3) vs.(15.8±5.0), t=1.652, P=0.113].There was no significant difference in the incidence of anastomotic hemorrhage[4.4%(4/90) vs.3.8%(3/78), χ2=1.182, P=0.133]and the incidence of urinary retention[4.4%(4/90) vs.6.4%(5/78), χ2=1.785, P=0.148].The time to first postoperative flatus[(52.4±23.2)h vs.(68.3±29.3)h, t=2.652, P=0.023]and length of postoperative hospital stay[(9.07±3.56)d vs.(10.68±4.94)d, t=2.785, P=0.017]in the LCA group were shorter than those in the non-LCA group.The incidences of anastomotic leakage in the LCA group and the non-LAC group were 2.2%(2/90)and 5.1%(4/78), respectively, and the difference was statistically significant( t=3.575, P=0.001). Conclusions:LCA preservation in laparoscopic-assisted radical resection of rectal cancer in elderly patients with rectal cancer is safe and feasible, reduces the incidence of anastomotic leakage, and shorten the time to first postoperative flatus and length of postoperative hospital stay.It has good practical clinical value.
ABSTRACT
Objective To assess the application of preoperative prognostic nutritional index (PNI) in evaluation the surgical risk and long-term prognosis for elderly patients with gastric cancer.Methods The clinical data of 205 patients aged ≥ 75 years with gastric cancer undergoing radical resection from January 2004 to December 2016 were analyzed retrospectively.The PNI value was calculated by serum albumin (g/L) +5 x lymphocyte count (x 109/L).The receiver operating characteristic (ROC) curve and Youden's index was used to determine the value of PNI in surgical risk and prognosis of patients.Patients were divided into low PNI group and high PNI group based on the cut-off value,the clinicopathological characteristics,postoperative complications and long-term survival were compared between two groups.Results The average PNI value of 205 patients was 47.3 ± 5.5.When 44.9 was set as the cut-off value with the maximal Youden's index,the sensitivity and specificity of PNI were 0.86 and 0.47,respectively.There were statistically significant differences between the two groups of patients in age(t =-2.16,P =0.032),BMI (t =4.88,P =0.000),Charlson comorbidity score (x2 =7.77,P =0.005),gastric resection range (x2 =8.63,P =0.003),postoperative complications (x2 =9.46,P =0.002).The incidence of complications in the high PNI group was 24.8％ (33/133),which was lower than that in the low PNI group (45.8％,33/72;x2 =9.46,P =0.002).Multivariate logistic analysis showed that age (P =0.032),Charlson coplications scal (CCS) (P =0.042) and PNI ＜ 44.9 (P =0.027) were independent risk factors for postoperative complications;PNI ＜ 44.9 (P =0.001),gastrectomy (P =0.011),lymph node dissection (P =0.000),tumor differentiation (P =0.001) and TNM stage (P =0.000) were independent prognostic factors for elderly patients with gastric cancer.Conclusions Prognostic nutritional index is a valuable clinical marker in evaluation of surgical risk and prognosis for elderly patients with gastric cancer.
ABSTRACT
Objective To investigate the comparison of clinical effects between two models of alimentary reconstruction after total gastrectomy in the elderly patients with gastric cancer.Methods 70 patients receiving alimentary tract reconstructions of Orr-type Roux-en-Y reconstruction (Orrtype,40 cases) and modified Brawn Ⅰ (30 cases) from January 2007 to December 2012 were retrospectively analyzed.The operative time,amount of bleeding,early postoperative complications and mortality,food intake,nutritional status and alimentary tract function were compared at 6 months after surgery.Results There were no significant differences between the two methods in the operative time [(198.8±14.0)min vs 233.5±30.7)min,t=-l.697,P＞0.05)],amount of bleeding [(420 ± 43) ml vs (340 ± 25) ml t =-1.956,P ＞ 0.05],and early postoperative complications [(17.5％ vs 16.7％),x2 =0.008,P＞0.05].However,times of liquid diet intake and semi liquid diet intake of the Orr-type reconstruction method was comparatively shorter than that of the modified Brawn Ⅰ [(4.8±2.1) d vs (7.6±2.4) d,and (9.5±3.6) d vs (11.5±3.7) d,t=-5.192,P＜0.05)].Nutritional status (weight,hemoglobin,total serum proteins and serum albumin) at 6 months after operation showed no significant differences between the two methods.But constituent ratio of Visick scores Ⅰ-Ⅱ of Orr-type was bigger than that of modified Brawn Ⅰ (86.7％ vs 62.5％,x2 =5.063,P＞0.05).Conclusions Orr-type Roux-en-Y reconstruction method can avoid reflux esophagitis,and the procedure is more simple than the modified Brawn Ⅰ method.Therefore,Orr-type Roux-en-Y reconstruction should be recommended as an adoptable method of digestive reconstruction after total gastrectomy for gastric cancer in the elderly patients.
ABSTRACT
Objective To evaluate the surgical modalities and prognosis in elderly patients with gastric cancer.Methods Sixty three gastric cancer patients aged ≥≥ 75 years underwent radical surgery,with D0 + D1 resection in 32 cases and D2 resection in 31 cases,in Beijing Hospital from January 2005 to December 2009.Results More lymph nodes were dissected in D2 group than those in D0 + D1 group (27.42 ± 12.75 vs.14.59 ± 12.11,t =-4.095,P ＜ 0.05).There was no significant difference in postoperative complication rate [25.81％ (8/31) vs.31.25％ (10/32),x2 =0.095,P ＞ 0.05] and perioperative death rate [3.23％ (1/31) vs.6.25％ (2/32),x2 =0.324,P ＞ 0.05] between two groups.The 5-year survival rate was higher in D2 group than that in D0 ± D1 group (47.3％ vs.21.4％,x2 =6.346,P ＜ 0.05).The 5-year survival rate was higher in POSSUM score (PS) ＜ 20 group than that in PS≥20 group (46.3％ vs.11.1％,x2 =5.492,P ＜0.05).In PS≥20 group,postoperative complication rate did not increase after D2 radical resection(1/8 vs.3/10,x2 =0.824,P ＞ 0.05).Univariate analysis showed that PS ＜ 20 was associated with the prognosis of patients (x2 =5.492,P ＜ 0.05).Cox proportional hazards model showed that lymph node metastasis (OR=4.103,95％ CI:1.790-9.405,P ＜ 0.05) and D2 radical gastrectomy(OR =0.313,95％ CI:0.158-0.620,P ＜ 0.05) were the independent factors associated with the prognosis of patients aged ≥ 75 years with gastric cancer (all P ＜ 0.05).Conclusion Standardized D2 lymph node dissection is beneficial for gastric cancer patients aged ≥75 years.PS ＜ 20,lymph node metastasis and D2 radical gastrectomy are associated with the prognosis of patients.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the risk of postoperative complications in elderly colorectal cancer patients over 65 years with comorbid cardiovascular diseases.</p><p><b>METHODS</b>A total of 381 elderly colorectal cancer patients over 65 years were pathologically diagnosed as colorectal adenocarcinoma and underwent the first surgery in Beijing Hospital during January 2013 and December 2014. Patients were divided into comorbid cardiovascular disease group (258 cases) and non-cardiovascular disease group (123 cases) according to the existence of comorbid cardiovascular disease. The morbidity of postoperative complication was compared between two groups.</p><p><b>RESULTS</b>There was no significant difference in the morbidity of postoperative complication between two groups [27.9%(72/258) vs. 29.3%(36/123), P>0.05]. According to the Clavien-Dindo classification of postoperative complications, the morbidities of complication at all levels between two groups were not significantly different(all P>0.05). But in terms of cardiovascular complications, the morbidity of comorbid cardiovascular disease group was significantly higher than that of non-cardiovascular disease group [7.4%(19/258) vs. 0.8%(1/123), χ=6.678, P=0.010], while no significant differences in pulmonary and abdominal complications were found between two groups(all P>0.05). The morbidities of other complications (deep vein thrombosis, urinary tract infection and renal complications, etc.) of comorbid cardiovascular disease group were lower than those in non-cardiovascular disease group [2.7%(7/258) vs. 8.1%(10/123), χ=5.733, P=0.017]. Different types of cardiovascular diseases, different levels of cardiac risk index and American Society of Anesthesiologists(ASA) rating were not significantly related to the patient's occurrence of postoperative complications(all P>0.05).</p><p><b>CONCLUSIONS</b>Surgery treatment for elderly colorectal cancer patients over 65 years with comorbid cardiovascular diseases is safe. However, strict cardiovascular monitoring should be performed and necessary measures should be carried out in time.</p>

<p><b>OBJECTIVE</b>To investigate the predictive value of preoperative Glasgow prognostic score (GPS) for the postoperative complications and survival in patients with colorectal cancer (CRC) undergoing laparoscopic radical resection.</p><p><b>METHODS</b>This retrospective study was conducted in the Beijing Hospital between January 2009 and January 2012. A total of 228 patients with primary CRC undergoing laparoscopic radical resection were analyzed. The GPS was constructed based on routine preoperative blood tests of C-reactive protein and serum albumin. The patients were classified into three groups according to GPS (GPS 0, 1, 2 groups). Survival curves were described by the Kaplan-Meier method and compared by the Log-rank test. The univariate and multivariate analyses were performed with the Cox proportional hazard model to identify the influence of GPS on prognosis in patients with CRC undergoing laparoscopic radical resection.</p><p><b>RESULTS</b>Preoperative CRP level was increased in 48 cases (21.1%), and preoperative serum albumin level was decreased in 104 cases (45.6%) in the whole group. These 228 patients were classified into 99, 105 and 24 patients in GPS 0, 1, 2 group respectively. GPS was significantly associated with age, preoperative body mass index (BMI), carcinoembryonic antigen (CEA), CA19-9, tumor location, tumor differentiation and TNM stage (all P<0.05). Postoperative complication rates of GPS 0, 1, 2 group were 6.1%, 14.3% and 70.8% respectively (χ=59.147, P=0.000). Serious postoperative complication rates were 3.0%, 6.7% and 58.3% respectively (χ=65.807, P=0.000). Univariate and multivariate analyses revealed that GPS was an independent risk factor of postoperative complications(HR=21.611, 95%CI: 5.936-78.681, P=0.000) and severe complications (HR=35.833, 95%CI: 7.364-174.355, P = 0.000). The 5-year survival rate was 50% and the average total survival time was 58.2 (95% CI: 54.6-61.7) months in the whole group. The median overall survival time in GPS 0, 1, 2 group was 74.6(95%CI: 70.4-78.7) months, 49.8(95%CI: 45.2-54.4) months and 27.8 (95%CI: 21.8-33.8) months respectively(χ=98.425, P=0.000). The median disease-free survival time was 73.9(95%CI: 69.2-78.7) months, 47.4 (95% CI: 41.6-53.1) months and 19.9 (95%CI: 14.8-25.0) months respectively (χ=91.305, P=0.000). GPS was an independent risk factor of disease-free survival (HR=4.840, 95%CI: 2.413-9.709, P=0.000) and overall survival (HR=6.267, 95%CI: 3.073-12.784, P=0.000).</p><p><b>CONCLUSIONS</b>GPS can be used as an effective predictor of the prognosis for patients with CRC undergoing laparoscopic radical surgery. Higher GPS suggests more postoperative complications and worse prognosis.</p>

Objective To investigate the changes of electrolyte metabolism in patients undergoing moderate elective abdominal operation,and explore its relationship with postoperative complications.Methods The clinical data of 1117 inpatients (age ≥ 18 years) who had undergone moderate elective abdominal operation in the Department of General Surgery of Beijing Hospital from January 1,2011 to December 31,2011 were retrospectively analyzed.They received postoperative fasting for ≥ 3 days,and the preoperative liver function and renal function were normal.The perioperative electrolyte changes and clinical outcomes were recorded.For patients with normal preoperative electrolytes but abnormal postoperative electrolytes,its potential correlations with the postoperative infections and total complications were analyzed.Results The rates of abnormal postoperative electrolytes were as follows:potassium,24.1％ ; sodium,6.4％ ; chloride,27.6％ ; calcium,61.7％ ; magnesium,16.3％ ; and phosphorus,71％.The vast majority of ion levels were below the normal levels.The total complication rate was 19.7％ and the postoperative infection rate was 17.19％.Univariate logistic regression analysis showed that the postoperative total and infective complications were significantly associated with the increased (P =0.007) or decreased (P =0.007) serum potassium,the decreased serum sodium (P =0.016),the decreased serum phosphorus (P =0.004),and the decreased magnesium (P =0.049).Conclusions Electrolyte decrease is common after moderate elective abdominal operations.There is a certain correlation between postoperative electrolyte decrease and postoperative complications.Therefore,attention should be paid to maintain electrolyte balance during the perioperative period.
ABSTRACT
Objective To explore the effect of age on clinical postoperative outcomes of elderly patients with colorectal cancer undergoing surgical treatment. Methods The clinical data of 1249 patients from January 1999 to December 2007 were analyzed retrospectively, and patients were divided into two groups according to age; the study group (≥75 years, n=312) and the control group (<75 years, n=937). Results (1) The average age was significantly higher in study group than in control group (t=33.09,P<0.05), and the rates of malnutrition risk, co-morbidity, tumor in right colon and local Iymphonodus metastasis were significantly higher in study group than in control group (x2=47.33, 130.75, 21.24 and 45.33, P<0.05). ( 2 ) The rates of preoperative surgical complications, bowel obstruction and emergency operation were significantly higher in study group than in control group (x2 =26.81, 34.14 and 10.72, P<0.05) . The rate of resection was significantly lower in study group than in control group (x2 =9.732, P<0.05). (3) The overall incidences of postoperative complications, general complications and mortality of perioperative period were significantly higher in study group than in control group (x2= 19.38, 20.75 and 10.11,P<0.05). (4) The two-year survival and five-year survival were significantly lower in study group than in control group (x2=11.91 and 27.17, P<0.05), but there were no significant differences in the cancer-specific two-year survival and five-year survival between the both groups. Conclusions Preoperative complications and co-morbidities, local tumor metastasis and postoperative nonsurgical complications adversely affect the postoperative outcomes for elderly patients with colorectal cancer.
