Objective To explore the feasibility and clinical application value of single-incision+1 laparoscopic surgery(SILS+1) in radical resection of colorectal cancer. Method Fifty patients with colorectal cancer admitted to our hospital from January 2023 to January 2025 were selected as the research subjects. They were divided into the observation group and the control group by the random number table method, with 25 cases in each group. Among them, the control group received traditional laparoscopic treatment, while the observation group received SILS+1 surgical treatment. The perioperative indicators, complication rates, and urination and defecation conditions under different treatment methods were compared. Result The operation time, first ambulation time and hospitalization time of the observation group were shorter than those of the control group, and the amount of bleeding during operation was less than that of the control group. The postoperative pain score of the observation group was lower than that of the control group, with significant differences (P ＜ 0.05). After treatment, the incidence of complications in the observation group was significantly lower than that in the control group, and the defecation and urination were better than those in the control group, with significant differences (P ＜ 0.05). Conclusion SILS+1 in the treatment of patients with colorectal cancer can shorten the operation time, reduce the amount of bleeding during operation, improve the status of defecation and urination, and the prognosis is safe.

Objective The value of radical resection of locally advanced breast cancer combined with flap transfer in the repair of chest wall defects. Method The clinical data of 15 patients with locally advanced breast cancer at stage Ⅲ B and Ⅲ C treated in Shandong Provincial Hospital Affiliated to Shandong First Medical University from January 2018 to June 2023 were retrospectively studied. The patients were treated by multiple means before operation. After the local lesions were controlled, the patients were treated with radical operation of breast cancer. At the same time, the rectus abdominis or latissimus dorsi myocutaneous flap was used to repair the chest wall defect. Summarize and analyze the basic situation, treatment and follow-up of patients. Result As of January 2025, 8 of the 15 patients survived and 7 died. The overall survival time was 1036d (280 ～ 2237d). The pathological subtypes of 15 patients included luminal type A (3 cases), luminal type B (4 cases), human epidermal growth factor receptor 2 positive breast cancer (5 cases) and triple negative breast cancer (3 cases). 14 cases received preoperative chemotherapy, 4 cases received preoperative targeted therapy, and 5 cases received preoperative interventional therapy. Latissimus dorsi myocutaneous flap was used in 5 cases and rectus abdominis myocutaneous flap in 10 cases. Recurrence occurred in 3 cases. The survival time was 1423 d (372 ～ 1498d); The survival time was 985.5d (280 ～ 2237d). Conclusion The comprehensive treatment mode combined with pedicled myocutaneous flap repair technology is helpful to control the lesions and improve the quality of life of patients with locally advanced breast cancer.

Objective To investigate the application effects of a risk prediction model for bowel preparation failure combined with time-based incentive theory in patients undergoing their first colonoscopy. Method A total of 360 patients from March to May 2025 in Qingdao Municipal Hospital were enrolled in the study. Participants were randomly assigned into three groups using a digital lottery system: a combined group (120 cases), a prediction group (120 cases), and a control group (120 cases). The control group received standard bowel preparation protocols, while the prediction group underwent bowel preparation guided by the risk prediction model. The combined group received bowel preparation protocols integrating both the risk prediction model and time-based incentive theory. The quality of bowel preparation, mental fatigue levels, tolerance to bowel preparation protocols, and patient satisfaction were assessed using the Boston bowel preparation scale, mental fatigue scale, bowel preparation tolerance scale, and bowel preparation satisfaction scale. Result In the combined group, 2 patients dropped out of the group due to their own work reasons, and a total of 118 patients were included in the study; In the prediction group, 3 patients dropped out of the group due to their own work reasons, and 3 patients dropped out of the group due to fear, a total of 114 cases were included in the study; In the control group, 2 patients were out of the group because they did not excrete clean after taking medicine and needed to do it again at a selected time, and 2 patients were out of the group because of their own work, a total of 116 cases were included in the study. The combined group demonstrated significantly higher scores in bowel preparation quality, mental fatigue levels, tolerability and tolerance to bowel preparation protocols compared to both the prediction group and control group(P ＜ 0.05). Conclusion Implementing a bowel preparation protocol that combines the risk prediction model for bowel preparation failure with time-based incentive theory in first-time colonoscopy patients can improve bowel preparation quality, reduce mental fatigue, enhance tolerance, and increase patient satisfaction.

Gastric cancer, a prevalent gastrointestinal malignancy in East Asian countries, particularly Japan, Korea, and China, is undergoing a significant shift in treatment paradigms, moving from radical resection toward function-preserving precision therapy. In March 2025, the 7th edition of the Japanese Gastric Cancer Treatment Guidelines was released, updating the indications and technical standards for function-preserving gastrectomy, thereby providing critical guidance for clinical practice. This article systematically reviews key updates in the new guidelines, including expanded indications for endoscopic treatment of early gastric cancer, technical nuances of various function-preserving procedures, and criteria for selecting appropriate surgical approaches. Special emphasis is placed on the clinical value of pylorus-preserving gastrectomy, subtotal gastrectomy, and anti-reflux reconstruction techniques following proximal gastrectomy. The findings aim to off er evidence-based insights and technical references for standardizing function-preserving gastrectomy in China.

Objective To explore the clinical value of using indocyanine green (ICG) in thyroid cancer surgery. Method 92 patients with papillary thyroid microcarcinoma treated in Dongtai people's Hospital from January 2023 to March 2024 were selected and randomly divided into observation group (n=46) and control group (n=46). All patients underwent unilateral radical thyroidectomy (unilateral thyroidectomy and isthmus resection + ipsilateral central neck lymph node dissection). The control group was treated with conventional radical thyroidectomy, and the observation group was treated with indocyanine green guided radical thyroidectomy. The perioperative indicators, serum calcium and parathyroid hormone levels, and the incidence of complications were compared between the two groups.

Objective To investigate the efficacy of percuteneous transhepatic cholangio drainage(PTCD) combined with the percutaneous gallbladder lithotripsy in the treatment of gallbladder stones combined with common bile duct stones. Method Clinical data from 43 patients with gallbladder stones and common bile duct stones treated between January and November 2024 in Nanjing Hospital Affiliated to Nanjing Medical University were collected. All patients underwent PTCD combined with percutaneous gallbladder lithotripsy for stone clearance. The clinical characteristics of the 43 patients were evaluated, and operative time, postoperative ventilation time, and hospital stay were recorded. Liver function indicators [alkaline phosphatase (ALP), total bilirubin (TBIL), aspartate aminotransferase (AST)] were assessed. The stone clearance rate was calculated, and stone recurrence and complications within 6 months postoperatively were recorded. Result The mean operative time was (114.31±18.74) min, postoperative ventilation time was (18.45 ± 2.52) h, and mean hospital stay was (5.96±1.32)d. All patients were discharged successfully. During postoperative recovery, total bilirubin levels decreased significantly at 24h postoperatively, followed by alkaline phosphatase and aspartate aminotransferase, and all returned to normal levels by 4 weeks postoperatively, with no cases of liver function deterioration. Among the 43 patients, 6 had mild biliary tract infection, 3 experienced biliary bleeding without other typical symptoms, and 1 developed acute suppurative cholangitis 12 h postoperatively, which improved after symptomatic treatment. In 4 patients with stones ≥ 20mm in diameter, magnetic resonance cholangiopancreatography confirmed successful one-time stone removal. No stone recurrence was observed in any patient, and 1 patient developed cholangitis. Conclusion PTCD combined with the percutaneous gallbladder lithotripsy demonstrates favorable clinical effi cacy in the treatment of gallbladder stones combined with common bile duct stones, with a high stone clearance rate and no severe complications.

Objective To explore the application value of modified same-stage endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic cholecystectomy (LC) in the treatment of gallstones with common bile duct stones.Method Sixty patients with gallstones and common bile duct stones admitted to the Department of General Surgery at Rudong Hospital of Traditional Chinese Medicine in Nantong City between January 2023 and December 2024 were enrolled. They were randomly divided into a staged group (30 cases, treated with ERCP followed by LC) and a same-stage group (30 cases, treated with modified same-stage ERCP and LC). Perioperative indicators, biochemical markers, and prognostic outcomes were compared between the two groups. Result There was no significant difference in stone clearance rate between the two groups (P ＞ 0.05). The surgical time, exhaust time, and hospitalization time of patients in the same group were shorter than those in the staging group. The VAS score on postoperative day 3 was lower than that in the staging group, and the total hospitalization cost was lower than that in the staging group. The serum amylase, total bilirubin, total bile acid, C reactive protein, interferon - γ, and interleukin-6 levels on postoperative day 5 were lower than those in the staging group, and the differences were significant (P ＜ 0.05); The quality of life score at 3 months after surgery was higher than that of the staging group (P ＜ 0.05); There was no significant difference in the incidence of complications and stone recurrence between the two groups of patients (P ＞ 0.05). Conclusion Compared to staged ERCP-LC surgery, the modified same-stage ERCP-LC approach offers advantages in shortening recovery time, reducing treatment costs, mitigating infl ammatory responses, and improving prognosis.

Objective To investigate the efficacy of transcatheter arterial chemoembolization (TACE) combined with molecularly targeted drugs in the treatment of intermediate and advanced hepatocellular carcinoma (HCC). Method Ninety cases of intermediate and advanced HCC patients who were treated in the Department of Gastroenterology of Zigong First People's Hospital from February 2023 to October 2024 were divided into an observation group and a control group according to a computerized randomization sequence. The control group received simple TACE treatment, and the observation group was combined with molecular targeted drug treatment on this basis. To compare the efficacy, serum tumor marker and adverse reactions between the two groups. Result The objective remission rate and disease control rate of the observation group were significantly higher than those of the control group (P ＜ 0.05). Before treatment, there was no significant difference in the levels of alpha fetoprotein and carcinoembryonic antigen between the two groups of patients (P ＞ 0.05). After treatment, the levels of alpha fetoprotein and carcinoembryonic antigen in both groups of patients decreased compared to before treatment, and the observation group was lower than the control group, with significant differences (P ＜ 0.05). In the observation group, all adverse reactions were grade 1 ～ 2, and no adverse reactions of grade 3 or above occurred, with a total of 9 cases and a total occurrence rate of 20.00%; In the control group, there were 17 cases of grade 1-2 adverse reactions and 3 cases of grade 3, totaling 20 cases, with a total incidence of 44.44%. The total incidence rate in the observation group was lower than that in the control group, and the difference was significant (P ＜ 0.05). Conclusion TACE combined with molecularly targeted drugs is more efficacious than TACE alone in the treatment of intermediate and advanced HCC, which can more significantly inhibit tumor progression, reduce AFP and CEA levels, and have controllable adverse effects.

Objective To explore the effects of different residual hernia sac management methods in laparoscopic transabdominal preperitoneal prosthetic(TAPP) and their impact on quality of life. Method 98 patients with inguinal hernia admitted to our hospital from January 2021 to December 2023 were randomly divided into two groups, with 49 patients in each group. All patients received TAPP treatment. The control group underwent complete dissection during the operation, while the experimental group underwent cross-sectional treatment. Compare the surgical related indicators, postoperative pain level, quality of life score, and incidence of postoperative complications between two groups. Result There were no significant differences in operative time, intraoperative blood loss, or VAS scores on postoperative day 1 and day 7 between the two groups (P ＞ 0.05). However, the experimental group exhibited significantly less groin area fluid accumulation, shorter hospitalization duration, and lower VAS scores on postoperative day 3 compared to the control group (all P ≤ 0.001). Preoperative quality of life scores showed no significant differences between the two groups (P ＞ 0.05). At 3 months post-operation, the experimental group demonstrated significantly higher quality of life scores across all domains compared to the control group (all P ＜ 0.001). The overall postoperative complication rate in the experimental group was 6.12%, significantly lower than the control group (22.45%) (P ＜ 0.05). Conclusion Transection of the residual hernia sac during TAPP surgery can reduce fluid accumulation in the inguinal area, alleviate pain, improve quality of life, and promote patient discharge as soon as possible.

At discharge, there was no significant difference in the levels of bacterial endotoxin and diamine oxidase between the two groups (P ＞ 0.05); At 3 and 6 months after discharge, the levels of bacterial endotoxin and diamine oxidase in the continuation group were significantly lower than those in the normal group (P ＜ 0.05). 7 patients in the general group had diff erent degrees of peripheral nerve, gastrointestinal and blood adverse reactions, which was higher than that in the continuation group, and the difference was significant (P＜0.05). Conclusion The implementation of Internet continuity nursing has a significant effect on reducing the adverse reactions of patients with colorectal cancer undergoing chemotherapy and maintaining gastrointestinal function. At the same time, it can also effectively relieve the negative emotions of patients and help them improve their self-care ability.

Objective To explore the influence of psychological nursing intervention based on the information-intervention-feedback-assessment-response (IIFAR) information nursing model on the pain degree and sleep quality of patients undergoing laparoscopic gastrointestinal surgery, and to provide a reference basis for clinical nursing intervention. Method A total of 76 patients who underwent laparoscopic gastrointestinal surgery at Jianhu County People's Hospital from January 2024 to January 2025 were selected and divided into an observation group and a control group, with 38 cases in each group based on different nursing models. Patients receiving care based on the IIFAR model were assigned to the observation group, while another 38 patients who received conventional care during the same period were selected as the control group. The pain levels, negative emotions, and sleep quality of the patients in both groups were compared before and after nursing interventions. Result Before nursing, there were no significant differences in the visual analog scale(VAS) scores, self-rating anxiety scale(SAS) scores, self-rating depression scale(SDS) scores, Pittsburgh sleep quality index(PSQI), and 36-item short form health survey(SF-36) scores between the two groups of patients (P ＞ 0.05). After nursing, the VAS, SAS, and SDS scores of the observation group were significantly lower than those of the control group (P ＜ 0.01); the PSQI score was lower, while the SF-36 score was higher, with significant differences (P ≤ 0.001). The nursing satisfaction of the observation group was significantly higher than that of the control group (P ＜ 0.05). Conclusion Psychological nursing interventions based on the IIFAR model can effectively reduce postoperative pain levels, improve sleep quality and quality of life, and enhance patient satisfaction in laparoscopic gastrointestinal surgery.

Acute appendicitis is a common acute abdominal disease, endoscopic retrograde appendicitis therapy (ERAT) as a new therapeutic technology, has a good therapeutic effect for this disease, and nursing cooperation plays a key role in the implementation of this technology. In this paper, we will review the key points and clinical experience of perioperative nursing care of ERAT in patients with acute appendicitis, summarize the focuses and methods of perioperative nursing care in different stages of ERAT and the impact on patients' prognosis, with a view to providing theoretical support for the improvement of the therapeutic effect of ERAT and the quality of patient care.
