BACKGROUND Radical resection of colon cancer under general anesthesia is one of the main treatment methods for this malignancy.However,due to the physiological charac-teristics of elderly patients,the safety of perioperative anesthesia needs special attention.As anα2-adrenergic receptor agonist,dexmedetomidine(Dex)has attracted much attention from anesthesiologists due to its stabilizing effect on heart rate and blood pressure,inhibitory effect on inflammation,and sedative and analgesic effects.Its application in general anesthesia may have a positive impact on the quality of anesthesia and postoperative recovery in elderly patients undergoing radical resection of colon cancer.METHODS A total of 165 colon cancer patients who underwent radical surgery for colon cancer under general anesthesia at Qingdao University Affiliated Haici Hospital,Qingdao,China were recruited and divided into two groups:A and B.In group A,Dex was administered 30 min before surgery,while group B received an equivalent amount of normal saline.The hemodynamic changes,pulmonary compliance,airway pressure,inflammatory factors,confusion assessment method scores,Ramsay Sedation-Agitation Scale scores,and cellular immune function indicators were compared between the two groups.RESULTS Group A showed less intraoperative hemodynamic fluctuations,better pulmonary compliance,and lower airway resistance compared with group B.Twelve hours after the surgery,the serum levels of TLR-2,TLR-4,IL-6,and TNF-αin group A were significantly lower than those of group B(P<0.05).After extubation,the Ramsay Sedation-Agitation Scale score of group A patients was significantly higher than that of group B patients,indicating a higher level of sedation.The incidence of delirium was significantly lower in group A than in group B(P<0.05).CONCLUSION The use of Dex as an adjunct to general anesthesia for radical surgery in elderly patients with colon cancer results in better effectiveness of anesthesia. 展开更多

BACKGROUND Colon cancer presents a substantial risk to the well-being of elderly people worldwide.With advancements in medical technology,surgical treatment has become the primary approach for managing colon cancer patients.However,due to age-related physiological changes,especially a decline in cognitive function,older patients are more susceptible to the effects of surgery and anesthesia,increasing the relative risk of postoperative cognitive dysfunction(POCD).There-fore,in the surgical treatment of elderly patients with colon cancer,it is of pa-ramount importance to select an appropriate anesthetic approach to reduce the occurrence of POCD,protect brain function,and improve surgical success rates.METHODS One hundred and seventeen patients with colon cancer who underwent elective surgery under general anesthesia were selected and divided into two groups:A and B.Group A received Dex before anesthesia induction,and B group received an equivalent amount of normal saline.Changes in the mini-mental state exami-nation,regional cerebral oxygen saturation(rSO2),bispectral index,glucose uptake rate(GluER),lactate production rate(LacPR),serum S100βand neuron-specific enolase(NSE),POCD,and adverse anesthesia reactions were compared between the two groups.RESULTS Surgical duration,duration of anesthesia,and intraoperative blood loss were comparable between the two groups(P>0.05).The overall dosage of anesthetic drugs used in group A,including propofol and remifentanil,was significantly lower than that used in group B(P<0.05).Group A exhibited higher rSO2 values at the time of endotracheal intubation,30 min after the start of surgery,and immediately after extubation,higher GluER values and lower LacPR values at the time of endotra-cheal intubation,30 min after the start of surgery,immediately after extubation,and 5 min after extubation(P<0.05).Group A exhibited lower levels of serum S100βand NSE 24 h postoperatively and a lower incidence of cognitive dysfunction on the 1st and 5th postoperative days(P<0.05).CONCLUSION The use of Dex in elderly patients undergoing radical colon cancer surgery helps maintain rSO2 Levels and reduce cerebral metabolic levels and the incidence of anesthesia-and surgery-induced cognitive dysfunction. 展开更多

Objective: To investigate the short-term efficacy of laparoscopic radical resection of right-sided colon cancer with two different surgeon positions and trocar placements. Methods: The data of 78 patients who underwent laparoscopic radical resection of right-sided colon cancer between January 2018 and August 2019 were retrospectively analysed. The surgical method was selected by the patients. The patients were divided into two groups according to the surgeons’ positioning habits and trocar placements. The group with the lead surgeon standing between the patient’s legs had 35 patients, and the group with the lead surgeon standing at the left side of the patient had 43 patients. The operation time, intraoperative blood loss, postoperative anal gas evacuation time, postoperative urinary catheter indwelling time, postoperative hospital stay, C-reactive protein (CRP) level on the first day after surgery, and postoperative pathological data and complications were compared between the two groups. Results: All patients underwent the laparoscopic radical resection of right-sided colon cancer, none converting to laparotomy. No significant difference (P > 0.05) in intraoperative blood loss (57.6 ± 21.3 ml vs 60.2 ± 35.3 ml), postoperative anal gas evacuation time (3.5 ± 1.1 d vs 3.8 ± 1.3 d), postoperative urinary catheter indwelling time (2.6 ± 1.3 d vs 2.4 ± 1.2 d), postoperative hospital stay (7.1 ± 1.8 d vs 7.5 ± 2.1 d), or CRP level on the first day after surgery (54.7 ± 9.6 mg/L vs 53.9 ± 8.2 mg/L) was detected between the two groups. The operation time was shorter in the group with the lead surgeon standing between the patient’s legs (185.2 ± 25.6 min vs 196.2 ±19.7 min) (P < 0.05). The two groups did not differ significantly in the tumour length (4.2 ± 1.3 cm vs 3.9 ± 1.5 cm), number of dissected lymph nodes (27.5 ± 11.6 vs 25.1 ± 15.4), pathological type, or postoperative pathological tumour-node-metastasis stage (P > 0.05). No patients died or had anastomotic fistula during their postoperative hospital stay, and the incidence of postoperative complications did not differ between the two groups (22.9% (8/35) vs 23.3% (10/42);P > 0.05). Conclusion: Under the principle of radical resection, the surgeon should adopt the most suitable standing position and trocar placement according to the specific situation. If the surgeon stands between the patient’s legs, this might shorten the operation time and promote a smoother surgery. 展开更多

Objective:To investigate the effect of laparoscopic radical resection of colon cancer on immune function, stress response and gastrointestinal hormones in patients with colon cancer. Method:140 patients with colon cancer admitted to a hospital from January 2016 to November 2017 were divided into control group and observation group according to the operation method, 70 cases in each group. The control group was treated with open radical resection of colon cancer, while the observation group was treated with laparoscopic radical resection of colon cancer. The changes of immune function, stress response, visceral protein and gastrointestinal hormone were compared between the two groups before and after treatment.Results:There was no significant difference in immune function, stress response, visceral protein and gastrointestinal hormone between the two groups before operation (P>0.05). The ratio of Th1 cells was decreased, while the ratio of Th2, Th17 and Treg cells was increased in the two groups (P<0.05). The proportion of Th1 cells in the observation group was higher than that in the control group,while the ratio of Th2, Th17 and Treg cells in the observation group was lower than that of the control group (P<0.05). The levels of Cor, E and NE were increased in the two groups (P<0.05). And the levels of Cor, E and NE in the observation group were lower than those in the control group (P<0.05). The levels of PA, TRF and RBP were decreased in the two groups (P<0.05). And PA, TRF and RBP levels were higher in the observation group than in the control group (P<0.05). The GAS, MTL and GIP levels were lower in the two groups (P<0.05). And the GAS, MTL and GIP levels in the observation group were higher than those in the control group (P<0.05).Conclusion: Laparoscopic radical mastectomy has little effect on the immune function of patients. It can alleviate the surgical stress response to a certain extent, which is beneficial to the recovery of gastrointestinal function and can be extended to clinical application. 展开更多

BACKGROUND Situs inversus totalis(SIT)is a rare group of congenital developmental malformations in the clinical setting,with all organs in the chest and abdomen existing in a mirror image reversal of their normal positions.Few reports have described laparoscopic surgery for colorectal cancer in patients with SIT,and it is considered difficult even for an experienced surgeon because of the mirror positioning.We present a case report of laparoscopic radical resection of a colonic splenic flexure carcinoma in a patient with SIT.CASE SUMMARY A 72-year-old male was referred to our hospital with colonic splenic flexure carcinoma,and computed tomography showed that all the organs in the chest and abdomen were inverted.Laparoscopic hemicolectomy with complete mesocolic excision was safely performed.The operating surgeon stood on the patient’s left side,which is opposite of the normal location.CONCLUSION Abdominal computed tomography is an effective method for diagnosing SIT preoperatively in patients with colonic splenic flexure carcinomas.Laparoscopic radical resection is difficult,but it is well established and safe.The surgeon should stand in the opposite position and perform backhand operations. 展开更多
