RESUMO

Radical resection is one of the most important treatment for rectal cancer, which requires not only removal of adequate bowel and mesorectum around the tumor, but also thorough lymphadenectomy. Besides, postoperative complications are surgeons' concerns as well. According to different ways to manage inferior mesenteric artery, procedures could be divided into two groups: inferior mesenteric artery (IMA) high ligation and low ligation, which lead to various outcomes of the extent of lymph nodes dissection, survival, preservation of intestinal blood supply, incidence of anastomotic leakage, and postoperative functions including defecation function, urinary function and sexual function. Author believes that for those patients with clinical stage T1, low ligation and D2 lymph nodes dissection could be considered. However, for patients with locally advanced carcinomas (clinical stage T2+or N+), especially suspicious metastasis of lymph nodes around IMA root, high ligation and D3 lymph node dissection is suggested to ensure en bloc resection. As for those patients with high risks for compromised intestinal blood supply, preservation of left colic artery plus D3 lymph nodes dissection might be a feasible way. Intraoperative indocyanine green fluorescent imaging might play a role in quality control of lymphadenectomy.

RESUMO

Objective: To compare the postoperative functional prognosis of transanal mesorectal excision (taTME) and conventional total mesorectal excision (TME) in rectal cancer. Methods: Totally 49 patients underwent taTME and 478 patients underwent conventional TME at Department of Gastroenterological Surgery, Peking University People's Hospital from January 2015 to December 2019 were retrospectively collected. Propensity score matching method was used to perform 1 versus 1 matching between the taTME and conventional TME groups, and 36 pairs of patients were successfully matched. After matching, the median age of patients in taTME group and conventional TME group was 60.5 (16.0) years and 60.5 (13.0) years (M(Q(R))), respectively, and the proportion of male patients was 66.7% (24/36) and 55.6% (20/36) , respectively. EORTC QLQ-C30 scale was used to assess quality of life, low anterior resection syndrome (LARS) scale and Wexner constipation score were used to evaluate anal function, international prostate symptom score (IPSS) was used to evaluate urinary function,international index of erectile function (IIEF) -5 and female sexual function index (FSFI) score were used to evaluate male and female sexual function, respectively, and generalized anxiety disorder (GAD-7) and patient health questionnaire (PHQ-9) scale were used to evaluate psych function. The t test, Mann-Whitney U test, χ(2) test, and Fisher exact test were used for comparison between groups, and Wilcoxon rank sum test or McNemar test was used for comparison between paired data. Results: There were no significant differences in surgery time, postoperative hospital stays, conversion rate, morbidity rate, surgery cost, and numbers of lymph node yield between the two groups (all P>0.05). Compared with the conventional TME group, the intraoperative blood loss in the taTME group was significantly higher (100 (100) ml vs. 80 (50) ml, U=424.5, P=0.010), the prophylactic stoma rate was significantly higher (96.9%(31/36) vs. 63.6%(21/36), χ(2)=11.218, P<0.01), the total hospitalization cost was significantly lower (74 297.7 (16 746.4) CNY vs. 91 781.3 (26 228.4) CNY, U=413.0, P=0.008). There were no significant differences in anal and urinary function between the two groups (LARS scalescore: Z=-0.513, P=0.608, Wexner constipation score: Z=-0.992, P=0.321, IPSS: Z=-1.807, P=0.071). In terms of psych function, significant difference in GAD-7 scale was seen between the two groups (Z=-2.311, P=0.021), patients with generalized anxiety disorder accounting for 26.7% (8/30) and 46.9% (15/32), respectively. Conclusions: Compared with conventional TME surgery, taTME has a significantly increased blood loss and prophylactic stoma rate. There are no significant difference in the incidence of postoperative anal, urinary, and sexual dysfunction between taTME and conventinal TME. taTME can alleviate the financial burden and general anxiety disorder to a certain extent.

RESUMO

RATIONALE: Cystic lymphangioma (CL) is a rare benign tumor resulting from a failure of the lymphatic system development. It may occur at any age but it is more frequent during childhood. Its clinical presentation and location are various but abdominal CL are uncommon. Among those, mesenteric presentation is the most frequent form whereas CL of the retroperitoneum are particularly rare. PATIENT CONCERNS: Herein, we report the case of a 17-years-old patient with no medical history who presented with right-upper quadrant (RUQ) pain, but no other symptom. Physical examination showed tenderness of the RUQ without distension. Lab tests were unremarkable. DIAGNOSIS: Abdominal computed tomography (CT) highlighted a retroperitoneal cystic mass potentially infiltrating the mesenterium, raising suspicion of a CL of the retroperitoneum. Diagnosis of CL was confirmed by histological analyses. INTERVENTION: Patient underwent an exploratory laparoscopy that infirmed infiltration of the mesenterium and allowed for resection. OUTCOMES: Postoperative course was uneventful and there is no evidence of recurrence after 14 months of follow-up. LESSONS: Although CL essentially occur in children, pediatric retroperitoneal CL is a rare finding, with only 21 cases identified in the literature.In summary, CL are benign tumors rarely located in the retroperitoneum. Despite performant imaging technologies, preoperative diagnosis is challenging. Whenever possible, laparoscopic resection should be the treatment of choice. Herein, we report the largest CL pediatric case laparoscopically resected, and the first review of the literature on the topic.

RESUMO

Membrane anatomy is the anatomy of mesentery in broad sense and its beds, which was merged from clinical results of surgical practice, optic observation and traditional theories contradiction or omission. Membrane anatomy is not only a plane, but also a body or bloc which is surrounded by fascia and serous membrane. It is not only fascia, but also a channel or pathway, in which the life event occurred. It is not only mesentery anatomy, but included mesentery beds, on which the mesentery was lied, even buried in. Following the new version of this anatomy map, surgical hazard during operation and postoperative oncological recurrence will be decreased simultaneously. And, following the definition of the mesentery in broad sense, new mesenteries will be discovered under macro surgery, which will optimize surgical operation and get better surgical and oncological results.

RESUMO

There has been an upsurge of the theory of membrane anatomy in China, but it is still in the initial stage of establishing preliminary framework. The concept of fasciae in membrane anatomy actually refers to the fasciae constituting the particular plane or the 'holy plane'. Therefore, the membrane anatomy can't simply be defined as the anatomical relationship among fascia. The application of the membrane anatomy is also not just to pursue the avascular plane in the surgical field. Nowadays, nonstandard anatomical terms and diversification of views impede the development of the theory of the membrane anatomy. Fasciae occur in embryonic stage, undergo a series of changes in rotation and fusion, and lose the original features, which bring difficulties in understanding the anatomy of fasciae. In this paper, we restore the origin and continuity of fasciae related to the colorectal surgery by cadaveric study, surgical observation and literature review. Taking the TME for example, we also discuss the core content about the fasciae and plane related to 'mesenteric envelope' and complete mesorectal excision. From the perspective of the fasciae integrity, we illustrate the definitions of important anatomical structure and standardized the terminology of fasciae. To study the origin and architecture of fasciae in the view of embryology, integrity and continuity will contribute to establish the standard theoretical system of membrane anatomy.

RESUMO

The theory of membrane anatomy is now widely accepted due to the observation of fine anatomical structure with the help of laparoscopic magnifying effect. From the perspective of systematic anatomy, the mesentery is considered as an integral organ in the theory of mesenteric anatomy. Interfascial anatomy belongs to regional anatomy, which focuses on the guiding significance of fascial space for operation. The theory of membrane anatomy belongs to surgical anatomy or applied anatomy, which emphasizes the anatomy of membrane and mesangial bed, and reveals the existence of 'metastasis V' in the mesentery. It is considered that the essence of membrane anatomy operation is to prevent cancer leakage. Various theories of membrane anatomy seek common ground while reserving differences, complement each other, and upgrade iteratively. They help to explain the structure and function of membrane from different perspectives and they are of great benefit to improve the quality of operations. Thus, they should be treated in an eclectic manner.

RESUMO

Different from classical surgical anatomy which only pays attention to the morphology and structure of human organs, modern membrane anatomy focuses on not only the relationship between morphology and structure, but also the biological behavior characteristics of tumors. Membrane antomy is a theoretical system with interpretation on both the structural and disease function, so it has been accepted by more and more gastrointestinal surgeons. However, the theoretical system of gastric membrane anatomy is not mature yet. The stomach and its mesentery have undergone complex rotation and fusion in the process of embryonic development, so that surgeons have different understandings of the gastric membrane anatomy. Therefore, it is easy to cause various confusion and misunderstanding, resulting in deviations between the theory of membrane anatomy and the practice of surgery. In the present study, the mesentery of the stomach is divided into different regions, and the embryonic development process is traced back. The application and compromise encountered in the radical gastrectomy of gastric cancer will be expounded according to the membrane anatomy theory combined with the author's experience of operation.

RESUMO

D2 lymphadenectomy combined with complete mesentery excision (CME) for advanced gastric cancer in recent years was a hotspot issue in China, while its safety and effectiveness have been proved. According to the Membrane anatomy of the stomach, both surgical approach and mesogastrium interval is particularly important in Laparoscopic radical gastrectomy. We summarized and shared the following clinical experience for medical colleagues. (1) Lymph nodes of right abdominal aorta-No.7,8,9,12-should be resection as an indivisible whole. This integrity tissue above the portal vein was supposed to the end of the dorsal mesentery of stomach and the continuation of Gerota fascia. (2) No.10 (splenic hilar lymph nodes) lymphadenectomy: The surgical approach enters the Gerota fascia between the left gastric artery(LGA) and the left alongside the splenic artery. When the extent of lymphadenectomy performed to cardia and upper margin of the spleen, then the ultrasonic scalpel should excise the lymph node along the splenic artery to the splenic hilum. (3) Esophagogastric junctional cancer: There is no consensus over the type of resection and the extent of lymphadenectomy that could be a standard of care for this category.While we recommended that paraesophageal lymph node dissection and digestive tract reconstruction should be completed in 3D laparoscopy vision. (4) Infracardiac bursa(ICB): Intentional entry into the ICB provides surgeons with a landmark to identify the location of the pleura, and inferior vena cava. (5)The application of endoscopic aspirator with flushing and electrocautery. The CME concept of gastric cancer emphasizes the membrane anatomy theory rather than the regional lymph node. The precision and homogeneity of the D2 procedure therapy of gastric cancer depend on complete mesentery excision, standard the surgical process, or approach. Only in this way can we find the avascular gaps easily and perfectly cover the extent of lymph node dissection required for the D2 procedure.

RESUMO

The standard treatment for advanced gastric cancer remains surgery-based comprehensive treatment. The D2 radical surgery has made outstanding contributions to the standarlization of gastric cancer surgery, which has improved patients' prognosis and quality of life. In recent years, neoadjuvant chemotherapy has achieved a certain effect on the treatment of advanced gastric cancer. With the continuous development of the concept of membrane anatomy in gastric cancer surgery, new surgical challenges have also been raised. For patients after neoadjuvant therapy, there is heated controversy in the possibility of completing radical gastrectomy with membrane anatomical concept for gastric cancer. We believe that if neoadjuvant therapy pushes mesenteric cancer cell back into the mesentery, theoretically membrane anatomy combined with neoadjuvant therapy is beneficial to the treatment efficacy of advanced gastric cancer. However, membrane anatomy has two important problems when combined with neoadjuvant therapy: (1) After neoadjuvant chemotherapy, there are varying degrees of edema around the stomach tissue, which will affect the visualization of anatomic planes. In addition, because the patients' coagulation function is damaged to a certain extent, it is difficult to avoid bleeding or minimize bleeding during the operation. Therefore, it is still controversial whether the patients with gastric cancer after neoadjuvant chemotherapy can undergo radical gastrectomy with membrane anatomy. (2) For patients with complete pathological remission, whether to obtain the maximum rate of pathological remission through intensive neoadjuvant therapy, or to obtain the survival benefit of patients with membrane anatomy surgery in clinic is still controversial. Faced with these confusions, multi-center clinical researches on the application of membrane anatomy surgery after neoadjuvant therapy is the only solution.

RESUMO

Membrane anatomy refers to the fascia and/or serosa enveloping the organs and their blood vessels and hanging on the posterior wall of the body cavity, which emphasizes the entirety and integrity of the membrane during operation. The concept can also be applied to most surgical operations. This article mainly expounds the application of the concept of membrane anatomy in the process of laparoscopic sleeve gastrectomy, which is embodied in the key steps of separating the greater omentum, mobilizing the fundus, mobilizing the posterior wall of the stomach, cutting the greater curvature of the stomach, reinforcing the staple line of the stomach, and suturing the greater omentum with staple line, in order to make the laparoscopic sleeve gastrectomy more accurate and precise with less bleeding, fewer complications and faster postoperative recovery.

RESUMO

Total mesorectal excision (TME) has been advocated as the golden standard of mid-low rectal cancer surgery for nearly 30 years. However, the complication of postoperative urinary and sexual dysfunctions due to intraoperative nerve injury has yet to be improved. Based on the concept of membrane anatomy, we carried out a systematic study on the important membrane anatomical structure anterior to the rectum--Denonvilliers' fascia. From multiple aspects including anatomy, physiology, histochemistry and surgical practice, we verified the importance of Denonvilliers' fascia for TME surgery in prevention of intraoperative nerve injury and postoperative urogenital dysfunction. Moreover, based on anatomical study of the surgical marker line of Denonvilliers' fascia (Wei's line) and surgical plane, we proved that total mesorectal excision with preservation of Denonvilliers' fascia (iTME) was feasible and practical. Therefore, we conducted a large multicentric randomized controlled trial (RCT). The mid-term result demonstrated that compared with traditional TME surgery, iTME was more effective in reducing the incidence of postoperative urinary and sexual dysfunctions in male patients with mid-low rectal cancer, without sacrifice of short-term tumor radical outcome. We believe that the final RCT result of iTME, based on membrane anatomy, will provide solid evidence for the update of concepts of rectal cancer surgery.

RESUMO

The introduction of total mesorectal excision and wider use of laparoscopic surgery pushed the field of colorectal surgery into an era of interfasical dissection. The Japanese suggestion of fascial arrangement of the trunk in a multilaminar, symmetrical and parallel way helps in better understanding of fascial relationship and interfascial planes surrounding the colon and the rectum. However, different interpretations of the multilayer retroperitoneal fascial relationship, complexity of fascial structures within the pelvis and dense adhesion between two apposed fasciae at special points make it still challenging for the surgeon to decide on the precise interfascial plane for colorectal mobilization. Small vessels on fasica propria of the rectum and various retroperitoneal fascia, especially ureterohypogastric fascia show distinctive features. The root of small vessels on fascia propria of the rectum helps to identify the anterolateral and posterolateral interfascial plane in the middle and low rectum. The longitudinal trajectory of small vessel on ureterohypogastric fascia and scarcity interfascial vascular communication between mesocolic and retroperitoneal fascia help the surgeon to find and stay in the interfacial plane during colorectal mobilization. More knowledge of fascial and interfascial plane will certainly help achieve better mesocolic mesorectal integrity and reduce the risk of injuries to autonomic nerves. More anatomical, histological and embryological studies are warranted with respect to relationship between small vessels and fasciae.

RESUMO

Objective: To explore the effects of the application of membrane anatomy concept in sleeve gastrectomy on postoperative nausea and vomiting (PONV) in patients with obesity or metabolic diseases. Methods: A retrospective cohort study was conducted. Clinical data of 88 patients with obesity or metabolic diseases who underwent laparoscopic sleeve gastrectomy in The First Affiliated Hospital of Jinan University from September 2018 to June 2019 were retrospectively analyzed. Forty patients underwent sleeve gastrectomy with membrane anatomy concept as membrane anatomy group, and the other 48 patients underwent traditional sleeve gastrectomy as traditional operation group. There were no significant differences in baseline data between the two groups (all P>0.05). The PONV score of and the times of antiemetic drugs used during 0-6 h and 6-24 h after operation were compared between the two groups. Higher PONV represents more serious nause and vomiting, the score ≥5 is defined as clinical significant PONV. Results: All patients of the two groups successfully completed the operation, and there was no conversion to open, reoperation, and operation-related death. The intraoperative blood loss in the membrane anatomy group was significantly less than that in the traditional surgery group [median: 5.0 (5.0, 5.8) ml vs. 10.0 (5.0, 10.0) ml, Z=-3.265, P=0.001]. There were no significant differences between the two groups in terms of operative time, postoperative hospital stay, gastroesophageal reflux, pain score and postoperative complications (all P>0.05). There was no postoperative bleeding or gastric leakage in either groups. There were no significant differences in PONV score, incidence of clinically significant PONV and use of antiemetics 0-6 h after operation between two groups (all P>0.05). From 6 to 24 hours after operation, compared with traditional surgery group, the membrane anatomy group had lower PONV score (4.6±0.9 vs. 5.1±0.7, t=-2.192, P=0.007), lower incidence of clinically significant PONV [55.0% (22/40) vs. 83.3% (40/48), χ(2)=8.414, P=0.004] and less use of antiemetics [3 times: 10.0% (4/40) vs. 27.1% (13/48), Z=-2.880, P=0.004]. Postoperative follow-up ranged from 1 to 6 months (median 3), 32 cases in membranous anatomy group and 38 cases in the traditional operation group were followed up. One case in the traditional operation group received symptomatic treatment in the local hospital due to functional intestinal obstruction 1 month after surgery and was discharged after recovery. The remaining patients had no postoperative complications and were not readmitted to hospital. Conclusion: Sleeve gastrectomy based on membrane anatomy in the treatment of patients with obesity or metabolic syndrome can make surgical procedure more precise and meticulous, reduce the intraoperative bleeding and the incidence of PONV.

RESUMO

Objective: To observe the anatomical architecture of rectosacral fascia and discuss the best plan for accurate peri-rectal dissection in laparoscopic/robotic total mesorectal resection (TME). Methods: A descriptive cohort study was carried out. A total of 127 patients with rectal cancer who underwent TME in the Department of Colorectal Surgery at the affiliated Union hospital of Fujian Medical University were included, patients' demographics with their pathological details and operation videos were collected for analysis. Another 20 high-definition images of post-TME surgical specimens were collected from our digital database. A total of 28 cadaveric models were examined at the Laboratory of Clinical Applied Anatomy, Fujian Medical University, to observe the anatomical details of rectosacral fascia. Results: (1) Anatomical observation showed that the pre-hypogastric fascia attaches to the proper fascia of the mesorectum in a horizontal arc posteriorly, forming the rectosacral fascia. If this fusion couldn't be identified and appropriately transected during posterior space dissection, it would be easy to destroy the proper fascia and dissect through the mesorectum resulting in residual mesorectum tissue. After the fascia transaction, the proper fascia of the mesorectum is still intact distally. The upper part of rectosacral fascia bilaterally re-separated again into the proper fascia and pre-hypogastric fascia. The pre-hypogastric fascia acts as a "fascia barrier" when dissecting the lateral space constantly from posterior to anterior. The right attachment of the rectosacral fascia was gradually transected. The pelvic plexus from the right S2-S4 was covered by the pre-hypogastric fascia which is considered the outer side layer of rectosacral fascia laterally. It was observed that the fascia continued with the anterior layer of the Denonvilliers' fascia, which has been transected during anterior space dissection. The proper fascia, which is the inner side layer of rectosacral fascia laterally, was still intact. The edge of the right rectosacral fascia attachment ran obliquely from the back and upward into the front direction. The left extension was similar to the right. (2) Cadaveric specimens: at the level of the lower edge of S4 vertebral body, the pre-hypogastric fascia fused with the proper fascia to form the rectosacral fascia. The right attachment margin of the rectosacral fascia was cut off step by step. The attachment margin of the rectosacral fascia went from the back and upward to the front downward direction. The right edge of rectosacral fascia attachment continued with the anterior layer of the Denonvilliers' fascia at the pre-rectal space and attached to the pre-hypogastric fascia laterally. The pelvic plexus sends out many tiny rectal branches on the anterolateral side, which pass through the transitional area between pre-hypogastric fascia and the anterior layer of the Denonvilliers' fascia to innervate the rectum. (3) TME specimens observation: the posterior attachment of rectosacral fascia was curved around the mesorectum with bilateral oblique attachments. The mesorectum was covered by fusion fascia below the posterior and bilateral attachment margin while it was covered only by the proper fascia above it. Conclusion: according to the morphological characteristics of rectosacral fascia, the rectosacral fascia should be dissected at the level of S4 vertebral body posterior to the rectum in an arc, shape and then enter the superior-levator space. Before dissecting the bilateral spaces, the anterior space of the rectum should be dissected first. The anterior layer of the Denonvilliers' fascia should be cut off into an inverted "U" shape, and then the lateral space should be dissected from anterior to posterior. Finally, the lateral attachment of rectosacral fascia was transected to ensure the integrity of the mesorectum without damaging the pelvic plexus branches and NVB.

RESUMO

According to the main features of transanal total mesorectal excision (taTME), we have designed a series of patented operating techniques, such as anal retractor, anal speculum and transanal port, to reduce the difficulty of transanal operation, shorten the surgeon's learning curve, and expand the indications of transanal surgery.

RESUMO

Robotic-assisted transanal total mesorectal excision (R-TaTME) has unique advantage in low rectal cancer. Single incision plus oneport (SIPOP) laparoscopic operation can synchronously cooperate with robotic-assisted transanal operation, in order to the difficulty of operation, improve the quality of operation and shorten the time of operation. A retrospective analysis was conducted on the clinical and pathological data of one patient who underwent SIPOP synchronously combined with R-TaTME + sigmoid-anal anastomosis + ileostomy at the Department of General Surgery, Army Characteristic Medical Center on September 11, 2019. This 71-year-old patient was male with body mass index of 24.08 kg/m(2) and received preoperative chemotherapy. Rectal adenocarcinoma was confirmed by colonoscopy biopsy, and distance from tumor lower edge to anal verge was 3 cm. MRI indicated T2N1 stage. The operation was completed successfully, and the transabdominal and robotic transanal surgery totaled 117 minutes, with 15 minutes for the robotic transanal preparation step. There was about 20 ml of intraoperative blood loss and no blood transfusion was performed. The patient was discharged 6 days after operation. No intraoperative or postoperative complications occurred. The postoperative TNM staging was stage I (pyT2N0cM0). No recurrence or metastasis was found at postoperative 7 month. It is a safe, effective and feasible technique for patients with low rectal cancer.

RESUMO

Total mesorectal excision (TME) is the standard operation for mid-low rectal cancer. The advancement of minimally invasive surgery for rectal cancer has never been interrupted, from the conventional open surgery and laparoscopic surgery to robotic surgery and similarly from the conventional transabdominal approach to the transanal approach. All these approaches have focused on ensuring oncological control and meanwhile minimizing surgical trauma, preserving pelvic autonomic nerves, accelerating postoperative recovery and rehabilitation accordingly. In this review, we summarized the current progress of robotic TME for the treatment of rectal cancer and evaluated its safety and efficiency from the perspective of oncological and functional outcomes. The advantages behind robotic TME rely mainly on dealing with difficult rectal cancer cases. Besides, the robotic surgery system shortens the learning curve. However, the superiority of robotic surgery in preserving autonomic nerve has not been yet confirmed compared with laparoscopic surgery. We proposed the partial preservation of Denonvilliers' fascia during robotic TME, in order to enlarge the pelvic space, ensure the integrity of anterior mesorectum, and preserve the autonomic nerves. To date, there is still a lack of evidence regarding robotic taTME in the treatment of rectal cancer. However, several technical defects regarding taTME itself, including the residual of the terminal mesorectum, the sacrifice of distal rectal stump, and cancer cell dissemination due to airflow during dissection, need to be solved. The reported higher rate of local recurrence with multifocal pelvic side involvement and the anorectal dysfunction after taTME restrict its widespread performance.

RESUMO

Objective: To evaluate the feasibility, safety and efficacy of robotic-assisted lateral lymph node dissection for mid-low advanced rectal cancer. Methods: A retrospective cohort study was performed. Inclusion criteria: (1) age between 18 and 80 years old; (2) rectal adenocarcinoma diagnosed by pathology; (3) without distant metastasis by preoperative CT or MRI; (4) patients underwent robotic-assisted total mesorectal resection (TME). Exclusion criteria: (1) conversion to open surgery; (2) multiple primary tumors; (3) patients underwent combined multiple organ resection. According to the above criteria, 137 patients undergoing robotic-assisted mid-low rectal cancer resection in the First Affiliated Hospital of Xi'an Jiaotong University from December 2016 to April 2019 were enrolled. Ninety-seven cases underwent robotic-assisted total mesorectal excision (TME group) and 40 underwent robotic-assisted total mesorectal resection with lateral lymph node dissection (LLND) (TME+LLND group, pelvic LLND was performed with neurovascular guidance to retain pelvic autonomic nerves in the order of the left side the first and then the right side). The propensity score matching of 1:1 was performed with R software, based on age, sex, BMI, ASA classification, distance from tumor to the anal verge, preoperative chemoradiotherapy history, preoperative abdominal surgery history, the size of tumors and TNM stage. The operative indicators, postoperative recovery, pathology and postoperative complications within 30 days were compared between the two groups. Results: A total of 72 cases were successfully matched (36 in each group), and there were no statistically significant differences in baseline data between the two groups (all P>0.05). The operation time of TME+LLND group was significantly longer than that of TME group [275.0 (180-405) minutes vs. 220.0 (140-320) minutes, Z=-3.680, P<0.001], while there were no statistically significant differences in blood loss during operation, time to postoperative first flatus, postoperative hospital stay, total hospital cost, tumor differentiation, and distal resection length of margin (all P>0.05). Circumferential resection margin was all negative in both groups. The number of harvested lymph modes in the TME+LLND groups was higher than that in the TME group [26 (18-37) vs. 14 (9-36), Z=-6.407, P<0.001]. In addition, there were no statistically significant differences in postoperative morbidity and Clavien-Dindo classification of complication within 30 days between the two groups (both P>0.05). Conclusions: Although robotic lateral lymph node dissection requires longer operation time, it is a feasible, safe and effective procedure.
