Colorectal cancer is a common malignant tumor of the digestive tract, and surgical resection is one of its main treatment methods. The reconstruction of the digestive tract in colorectal surgery is a crucial step that directly affects the postoperative recovery and quality of life of patients. The key points of colorectal surgery reconstruction include reasonable planning of the digestive tract reconstruction path, trying to preserve the neural innervation and blood supply of the intestine as much as possible, and selecting appopriate surgical instruments and anastomotic materials. This article aims to explore in depth the quality control strategies for gastrointestinal reconstruction in colorectal surgery, including precise preoperative evaluation, optimized surgical plans, meticulous intraoperative procedures, and effective quality monitoring systems. By comprehensively analyzing and elaborating on these aspects, scientific basis and practical guidance are provided to improve the quality of digestive tract reconstruction in colorectal surgery.

Since the concept of GIST was proposed in 1983, the diagnosis and treatment of GIST in China have continuously progress. Over the two decades from 1990 to 2010, the diagnosis and treatment of GIST had achieved a foundation of development through the collective efforts of GIST scholars, from the first pathological review to the first expert consensus. The period from 2010 to 2020 marked rapid development. Besides the updates of expert consensus, other relevant expert consensus was published regarding pathology, surgery, targeted therapy, therapeutic drug monitoring, and patient' management. Based on the above development, China's first GIST guideline, the "CSCO Gastrointestinal Stromal Tumor Diagnosis and Treatment Guidelines (2020 Edition)", was published. This guideline considers regional development disparities, accessibility of treatments and diagnostic methods, and the social value of cancer care, maintaining its scientific rigor, fairness, and timeliness. Over the past 30 years, the diagnosis and treatment of GIST in China significantly development. However, we should recognize that further development must require more original Chinese research, which would better benefit the Chinese population.

Cervical Bronchogenic cysts (BC) is a rare congenital abnormality caused by abnormal budding of the embryonic foregut diverticulum. Mediastinal and intrapulmonary types are the most common sites of occurrence, and thyroid BC is rare. This article aims to report a case of resection of thyroid BC with video-assistance technology to improve the understanding of the imaging, pathology and clinical aspects of this disease.

Papillary thyroid microcarcinoma(PTMC),which lacks lymph node metastasis,distant metastasis,extra-thyroid invasion,high-risk subtypes,and invasion of the trachea or recurrent laryngeal nerve,may be classified as low-risk PTMC based on clinical assessment.Surgical intervention such as lobectomy or total thyroidectomy is the primary treatment modality for PTMC.This study comprised 124 patients who underwent conformal thyroidectomy and revealed that this innovative surgical approach yielded long-term oncological outcomes comparable to those who received lobectomy or total thyroidectomy.The surgical intervention may play a significant role in the comprehensive management of PTMC,while the implementation of PTMC precision medicine necessitates the utilization of genetic testing,molecular typing,and other advanced technologies to detect early-stage high-risk factors like lymph node microinvasion and integrate biology-based surgery concept for optimal outcomes.

Objective:To explore the clinical features, treatment and prognosis of patients with pneumatosis cystoides intestinalis (PCI).Methods:The clinical data of 25 PCI patients at Peking University People's Hospital admitted from Jan 2011 to Dec 2020 were retrospectively analyzed .Results:Among these 25 PCI patients, there were 9 males and 16 females with a median age of 69 (55-78) years. Six patients were asymptomatic, while the main complaint of the remaining patients was abdominal pain (12 cases), followed by diarrhea (4 cases), constipation (2 cases), and abdominal distension (1 case). Fifteen patients with PCI also had hypoalbuminemia. The main radiological manifestation of PCI was the presence of multiple gas-filled cysts within the intestinal wall, with 23 cases occurring in the colon and 17 cases combined with free intra-abdominal gas. All patients were cured with conservative treatment, with no PCI-related deaths during follow-up .Conclusions:PCI is a rare gastrointestinal disease with atypical clinical manifestations. Conservative management is an effective treatment with good prognosis.

Objective:To investigate the effect of tumor deposit(TD) on the prognosis of patients with gastric cancer after radical surgery.Methods:A retrospective analysis was performed on gastric cancer patients who underwent radical surgery at the Department of Gastrointestinal Surgery, Peking University People's Hospital from Jan 2021 to Dec 2023. The relationship between the status of tumor deposit and clinicopathological features, as well as the impact on the overall postoperative survival of gastric cancer patients were evaluated.Results:Pathological examination revealed that among 212 patients with gastric cancer, 12 patients (5.1%) had tumor deposits (TD). The occurrence of TD was found to be associated with preoperative T stage, N stage, and extramural vascular invasion (EMVI) (all P<0.05). During the follow-up period, 31 patients experienced recurrence, metastasis, or death. The COX multivariate analysis indicated that N stage ( P=0.07), preoperative serum CEA level ( P<0.001), EMVI ( P=0.001), and TD ( P=0.011) were independent risk factors affecting the overall postoperative survival . Among patients who received neoadjuvant therapy and on pT4 stage, pN+ status, and EMVI status before surgery, the presence of TD was closely correlated with overall survival. Patients with TD had a worse prognosis and shorter overall survival( P<0.05). Conclusion:Tumor deposit is an important risk factor affecting the prognosis of patients after radical gastrectomy and may be a predictive biomarker of early peritoneal metastasis.

The anastomotic vessels between the superior mesenteric artery and the inferior mesenteric artery are vital to maintain the blood supply of the anastomosis and residual colon after colectomy. However, current studies of anastomotic vessels are facing four major obstacles: confusing nomenclature, large variability in data, diversification of research methods and incomplete information records. The existence of marginal artery has been widely proved, and its significance for blood supply is well recognized by relevant studies. In contrast, the Riolan′s arch, whose connotations constantly changed over history, can not refer to a specific structure accurately. Researchers should abolish the controversial names such as Riolan′s arch, select appropriate research methods and record the anastomotic vessels in detail, so as to improve the comparability between different results. The study of anastomotic vessels can help us to identify potential vascular disease, select the appropriate surgical approach, and provide appropriate treatment of the vessels in the operating area, so as to provide a theoretical foundation and practical basis for fine surgical maneuvers.
