ABSTRACT
Objective:To evaluate the role of permanent sigmoid colostomy created through the extraperitoneal route combined with pelvic floor peritoneal reconstruction after laparoscopic Miles surgery for lower rectal cancer.Methods:A total of 88 patients undergoing laparoscopic Miles surgery at Gastrointestinal Center of Northern Jiangsu People's Hospital from Apr 2016 to Apr 2020 were divided into extraperitoneal ostomy group(40 cases) and transperitoneal ostomy group (48 cases).Results:There were no significant differences in operating time, stoma-forming time, intraoperative blood loss, first exhausting time, first defecation time and hospital stay between the two groups (all P>0.05). There were 17 cases of complications in observation group vs. 16 cases in control group ( χ2=0.782， P=0.376). After 12 months, the complications in observation group were significantly less than control group ( χ2=8.601， P=0.003). There was no parastoma hernia in observation group vs.7 in control group ( χ2=4.502， P=0.034). The satisfaction rate of ostomy control defecation in observation group (70%) was significantly higher than that in control group (38%) after 12 months ( P=0.001). Conclusion:A permanent sigmoid colostomy created through the extraperitoneal route combined with pelvic floor peritoneal reconstruction during laparoscopic Miles surgery is safe and feasible, with fewer complications and better defecation function than that of the stoma through transperitoneal approach.
ABSTRACT
Objective:To compare laparoscopic-assisted distal gastrectomy (LADG) and laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG) for early gastric cancer (EGC). Methods:Firty-two EGC patients from Sep 2018 to Aug 2020 in Northern Jiangsu People's Hospital were divided into LAPPG group ( n=21) and LADG group ( n=31). Results:The average operation time in the LAPPG and LADG groups was (173±30) min and (144±31)min, respectively ( t=3.34, P=0.002). The average levels of Hb and albumin (ALB) in the LAPPG group were (128.7±16.0) g/L and (41.2±4.8) g/L respectively 3 months after gastrectomy, ( t=2.482, P=0.016 and t=2.097, P=0.041) compared to LADG group at (118.2±14.1) g/L, (38.4±4.7) g/L. According to the Clavien-Dindo classification, the incidence of complications above grade Ⅱ was 19.0% in LAPPG group and 22.6% in LADG group, and the difference was not statistically significant ( χ2=0.007, P=0.934). The PGSAS-45 questionnaire scoring results show that LAPPG scores were lower in the dumping syndrome and life dissatisfaction subscales ( t=-2.706, P=0.008 and t=-2.893, P=0.004) Conclusion:LAPPG procedure for the treatment of EGC patients is safe and feasible, promoting early postoperative nutritional recovery. In adition to less dumping syndrome and better postoperative quality of life .

ABSTRACT
Objective:To explore the clinical value of laparoscopic abdominoperineal resection(LAPR) with pelvic peritoneum closure for patients with low rectal cancer.Methods:The clinicopathological data of 90 patients with low rectal cancer who underwent laparoscopic abdominoperineal resection from Mar 2014 to Jan 2019 at the Subei People's Hospital of Jiangsu Province were retrospectively analyzed. These patients were divided into closed pelvic floor peritoneum group (study group, n=42) and without pelvic floor peritoneum group (control group, n=48) . Results:The postoperative hospital stay of the study group was shorter than that of the control group[(10.8±3.0) d vs. (12.4±3.1) d, t=2.569, P=0.013]. There was no statistically significant difference in the operation time , intraoperative blood loss , time to first flatus ,first time of getting out of bed between the two groups. Perineal incision infection and perineal incision dehiscence occurred in 2 cases and 1 case in the study group, and 10 cases and 9 cases in the control group respectively (χ 2= 5.007, P=0.025; χ 2=6.077, P=0.033). In the study group, there were 0 cases of perineal hernia, 1 case of pelvic floor peritoneal hernia and 2 cases of adhesive intestinal obstruction, while those in the control group were 7 cases, 8 cases and 9 cases, respectively (χ 2=6.642, P=0.013; χ 2=5.079, P=0.033; χ 2=4.085, P=0.043). Conclusion:Laparoscopic abdominoperineal resection with pelvic peritoneum closure significantly reduces the incidence of postoperative perineal-related complications and shorten postoperative hospital stay.
ABSTRACT
Objective To compare the early outcomes of laparoscopic and open resection and evaluate the safety and feasibility of laparoscopic surgery in patients with colorectal cancer aged ≥ 70 years.Methods A total of 91 consecutive patients with colorectal adenocarcinoma underwent surgery in Yizheng City People's Hospital between Jan.2009 and Dec.2015.In 91 patients included in this study,38 received laparoscopic surgery and 53 underwent open surgery.Main outcome measures were clinical data,postoperative recovery status and short-term outcomes.Results There were no significant differences between two groups with respect to demographic indicators,clinicopathological results and chronic comorbidities had no significant difference between two groups.No death cases occured in both groups.One patient in the laparoscopic group required conversion to open surgery due to ureteral injury.Laparoscopic surgery was associated with significantly longer operating time [(238 ± 71.3) minutes vs (175 ± 60.8) minutes,P ＜ 0.001],less estimated blood loss [(145 ± 58 ml) vs (186 ± 45) ml,P ＜ 0.001)],a shorter postoperative hospital stay [(11.9 ± 3.9) days vs (14.5 ± 3.7) days],lower overall postoperative complication rate (23.7％ vs 45.3％,P =0.035),wound-related complication rate (2.6％ vs 22.6％,P =0.017) when compared with open surgery.Quality of surgical specimen,lymph nodes harvested were not significantly different between two groups.Conclusion Laparoscopic colorectal cancer surgery is safe and feasible in elderly patients,associated with better short-term outcomes when compared with open surgery.
ABSTRACT
Objective To evaluate the safety and feasibility of totally laparoscopic cholecystolithotomy.Methods Patient baseline characteristics of all 34 totally laparoscopic cholecystolithotomy (TLC) were collected in a database.This group was compared with 34 matched patients who underwent the laparoscopic cholecystectomy (LC) in the same period.Retrospectively,intraoperative and postoperative data were added.Results Operatingtime was significantly longer in the TLC group(124.56 min vs 78.50 min,P ＜0.01).The mean hospitalization expenses of operation was significantly higher in the TLC group(10 970.85 yuan vs 8 666.72 yuan,P ＜0.01).Although not significant less patients have the symptoms of postoperative dyspepsia or diarrhea were seen in the TLC group compared with the LC group (2 vs 6,P =0.26).Intraoperative details and postoperative results such as,blood loss,hospital stay,exhaust time,abdominal bleeding,bile leakage,incision infection have no significant difference.One case of gallstone recurrence was detected in TLC group.No stone recurrence was reported in common bile duct in LC group.Conclusions TLC is effective and feasible for chronic calcular cholecystitis and is particularly favorable for thepatients with medical insurance.However,this approach is technically demanding and should be performed by experienced surgon.
ABSTRACT
The laparoscopic surgery is increasingly widely used in the treatment of malignant gastrointestinal cancer.Its technical feasibility has been recognized,however,there are disagreements in the evaluation of its safety,the tumor metastasis of port-site and intra-abdominal after operation has been the focus of controversy in medical community.Its major impact mechanism including the change of peritoneal microenvironment,immunity,mechanical pressure of pneumoperitoneum,biological behavior of tumor cells and so on.The specification must be taken before surgery,strictly control the laparoscopic gastrointestinal cancer surgery indications,minimize the pneumoperitoneum pressure,shortem operative time,with He gas instead of CO2 pneumoperitoneum or free pneumoperitoneum laparoscopic techniques and other effective measures to reduce the risk of tumor metastasis.
ABSTRACT
ObjectiveTo investigate the lethal effect of hyperthermic CO2 pneumoperitoneum on gastric cancer cells and then further study the feasility and safety of inflating hyperthermic CO2 in gastric cancerpatients when performing laparoscopic operation.MethodsAn in vitro hyperthermic CO2 pneumoperitoneum experimental model was built,then according to the experimental purpose,the stomach carcinoma cell-7901 was grouped:hyperthermic CO2 pneumoperitoneum group; pure hyperthermia group; pure CO2 group;control group.After processing according to groups,cell proliferation was detected by Cell Counting Kit-8(CCK-8),cell apoptosis was detected by Annexin V-fluorescein isothiocyanate/propidium iodide flow cytometry and Hoechst 33342/propidium iodide fluorescent microscopy.ResultsThe reaults of cell proliferation detection showed that hyperthermic CO2 pneumoperitoneum could significantly inhibit proliferation of stomach carcinoma cell-7901 when compared with pure hyperthermia group,pure CO2 group and control group (P ＜ 0.05 ).The results of apoptosis detection showed that hyperthermic CO2 pneumoperitoneum could significantly induce apoptosis of stomach carcinoma cell-7901 and the gastric cancer cells apoptosis showing bright blue under the fluorescent microscope.ConclusionsHyperthermic CO2 pneumoperitoneum could significantly inhibit proliferation of stomach carcinoma cell-7901 and probably kill it by inducing apoptosis.
ABSTRACT
