ABSTRACT
OBJECTIVE@#To explore the clinical value of three-dimensional (3D) visualization technique in laparoscopic D3 radical resection of right colon cancer.@*METHODS@#We retrospectively analyzed the clinical data of 73 patients with right colon cancer undergoing laparoscopic D3 radical operation in our hospital between May, 2019 and March, 2021. Among these patients, 41 underwent enhanced CT examination with 3D visualization reconstruction to guide the actual operation, and 32 underwent enhanced CT examination only before the operation (control group). In 3D visualization group, we examined the coincidence rate between the 3D visualization model and the findings in surgical exploration of the anatomy and variations of the main blood vessels, supplying vessels of the tumor, and the tumor location, and the coincidence rate between the actual surgical plan for D3 radical resection of right colon cancer and the plan formulated based on the 3D model. The operative time, estimated blood loss, unexpected injury of blood vessels, number of harvested lymph nodes, mean time of the first flatus, complications, postoperative hospital stay and postoperative drainage volume were compared between the two groups.@*RESULTS@#The operative time was significantly shorter in 3D visualization group than in the control group (P < 0.05). The volume of blood loss, proportion of unexpected injury of blood vessel, the number of harvested lymph nodes, time of the first flatus, proportion of complications, postoperative hospital stay and postoperative drainage volume did not differ significantly between the two groups (P > 0.05). In the 3D visualization group, the 3D visualization model clearly displayed the shape and direction of the colon, the location of the tumor, the anatomy and variation of the main blood vessels and the blood vessels supplying the cancer, and showed a coincidence rate of 100% with the findings by surgical exploration. The surgical plan for D3 radical resection of right colon cancer was formulated based on the 3D model also showed a coincidence rate of 100% with the actual surgical plan.@*CONCLUSION@#The 3D visualization reconstruction technique allows clear visualization the supplying arteries of the tumor and their variations to improve the efficiency, safety and accuracy of laparoscopic D3 radical resection of right colon cancer.

Objective: To investigate the short-term clinical efficacy and complications of laparoscopic radical right hemicolectomy via the head-tail and medial approaches. Methods: Clinical data of 91 patients admitted for laparoscopic radical right hemicolectomy at Affiliated Hospital of Xuzhou Medical University between January 2015 and December 2019 were retrospectively analyzed. Of those patients, 50 and 41 patients underwent laparoscopic radical right hemicolectomy via the head-tail and medial approaches, respectively. According to the clinical indicators such as operation time, amount of intraoperative blood loss, rate of injury of Henle trunk and its branches (an indicator of conversion to laparotomy), number of lymph nodes dissected, number of positive lymph nodes, postoperative intestinal function recovery time, postoperative abdominal drainage tube removal time, postoperative hospitalization time, and postoperative complications, the potential advantages of laparoscopic radical right hemicolectomy via the head-tail approach were evaluated and analyzed. Results: The operation time was significantly shorter [180 (150-188) min vs. 210 (180-255) min, P0.05). Conclusions: Compared with the commonly used medial approach in clinical practice, laparoscopic radical right hemicolectomy via the head-tail approach showed obvious improvement with respect to operative time, amount of intraoperative blood loss, and the injury rate of Henle trunk and its branches. Thus, the head-tail approach had higher operative safety and is thus worthy of further clinical application.
ABSTRACT
Objective@#To compare the evaluation effects of abdominal enhanced computed tomography (CT) coronal imaging versus three-dimensional (3D) vascular reconstruction for critical blood vessels in right colon cancer.@*Methods@#The retrospective and descriptive study was conducted. The clinicopathological data of 50 patients with right colon cancer who were admitted to Changhai Hospital Affiliated to Naval Medical University from January to September in 2018 were collected. There were 33 males and 17 females, aged from 33 to 86 years, with an average age of 63 years. All the 50 patients underwent abdominal multi-slice CT examination on the same CT equipment. The CT examination data were analyzed by two-dimensional (2D) coronal imaging and 3D vascular reconstruction. Observation indicators: (1) anatomical type of Henle trunk; (2) the length of Henle trunk and surgical trunk; (3) the positional relationship between ileocolic vein (ICV) and ileocolic artery (ICA). Measurement data with normal distribution were represented as Mean±SD, and count data were represented as absolute numbers. Kappa coefficients were used to measure the consistency between anatomical types of Henle trunk on 2D coronal images and on 3D vascular reconstructed images. Pearson coefficients were used to evaluate the correlation between the length of Henle trunk and surgical trunk on 2D coronal images and on 3D vascular reconstructed images. Bland-Altman method was used to assess the consistency between the length of Henle trunk and surgical trunk on 2D coronal images and on 3D vascular reconstructed images.@*Results@#(1) Anatomical type of Henle trunk: on the 2D coronal images, 43 of 50 patients had the Henle trunk and 7 had no Henle trunk. On the 3D vascular reconstructed images, 44 of 50 patients had the Henle trunk and 6 had no Henle trunk. There were 2, 21, 17, 3 patients classified as type 0, Ⅰ, Ⅱ, Ⅲ of Henle trunk on the 2D coronal images of 43 patients. There were 6, 19, 16, 3 patients classified as type 0, Ⅰ, Ⅱ, Ⅲ of Henle trunk on the 3D vascular reconstructed images of 44 patients. Six patients with no Henle trunk, 2 in type 0, 18 in type Ⅰ, 15 in type Ⅱ, and 3 in type Ⅲ had the same anatomical type of Henle trunk on the 2D and 3D images. The consistency between anatomic types of Henle trunk on 2D coronal images and on 3D vascular reconstructed images was high (κ=0.830, 95% confidence interval: 0.705-0.956, P<0.05). (2) The length of Henle trunk and surgical trunk: on the 2D coronal images, 43 of 50 patients had the length of Henle trunk as (10±5)mm, and 42 of 50 patients had the length of surgical trunk as (34±12)mm. On the 3D vascular reconstructed images, 44 of 50 patients had the length of Henle trunk as (9±5)mm, and 43 of 50 patients had the length of surgical truck as (35±12)mm. The correlation between the length of Henle trunk and surgical trunk on 2D coronal images and on 3D vascular reconstructed images was positive (r=0.872, 0.979, P<0.05). Bland-Altman plot showed a high consistency between the length of Henle trunk and surgical trunk on 2D coronal images and on 3D vascular reconstructed images (P<0.05). (3) The positional relationship between ICV and ICA: on the 2D coronal images, 24 of 50 patients had anterior crossing between ICV and ICA, 26 had posterior crossing between ICV and ICA. On the 3D vascular reconstructed images, 24 of 50 patients had anterior crossing between ICV and ICA, 26 had posterior crossing between ICV and ICA. There was a complete consistency in the positional relationship between ICV and ICA on the 2D coronal images and on 3D vascular reconstructed images.@*Conclusion@#Abdominal enhanced CT coronal imaging and 3D vascular reconstruction have the similar evaluation effects for position of critical blood vessels in right colon cancer, with a good consistency.

ABSTRACT
OBJECTIVE: To investigate the feasibility and short-term outcomes of laparoscopic D3 lymphadenectomy along the left of SMA for right colon cancer.METHODS: The clinical data of 134 patients with right colon cancer admitted from June 2015 to March 2017 in Department of Gastrointestinal Surgery,Ruijin Hospital,Shanghai Jiao Tong University School of Medicine were analyzed retrospectively. A total of 57 patients received the laparoscopic D3 lymphadenectomy along the left of SMA and 77 patients received the laparoscopic D3 lymphadenectomy along the left of SMV.RESULTS: There was no statistical difference between the two groups in operation time,intra-operative blood loss,time of liquid intake and post-operative hospital stay,but the SMA group had a longer duration of tube drainage and larger total volume of drainage[(471.4±285.6)mL vs.(352.2±305.7)mL,(7.0±4.9)d vs.(5.7±2.0)d,P=0.02 和 P=0.03]. The SMA group harvested more lymph nodes than the SMV group(26.5±6.7 vs. 21.3±7.8,P<0.0001). However,the SMA group had a higher rate of post-operative complications(28.1% vs. 13.0%, P=0.04).CONCLUSION: Laparoscopic D3 lymphadenectomy along the left side of SMA for right colon cancer is feasible but had a higher rate of post-operative complications.

ABSTRACT
Right colon cancer is a kind of clinically common colorectal cancer.Surgical resection is the main treatment and the only curative method for patients.Improvement of surgical methods in recent years is one of the hotspots in the surgical treatment of colorectal cancer.There are controversies in laparoscopic surgery or traditional open surgery,intestine resection extent,D3 radical surgery or complete mesocolic excision,selective arterial guidance or venous guidance,pyloric lymph nodes (No.6 group lymph nodes) dissection,and most of the issues are currently lacking of prospectively randomized controlled trials.Therefore,this article discusses the above problems.At the same time,in view of the complicated operation of right hemicolectomy,and the greater risk of surgery,the author consulted the relevant literature and combined his clinical experience to introduce the key techniques of the operation.
ABSTRACT
Objective To evaluate the experience of laparoscopic complete mesocolic excision (CME) for right colon cancer.Methods 45 patients with right colon cancer underwent laparoscopic CME were selected as research subjects(laparoscopy group),and 40 patients with right colon cancer underwent open CME were selected as control group(open group).The clinical effects of the two groups were observed .Results All the 45 cases were successfully performed with laparoscopic CME and 40 specimens were evaluated pathologically as mesocolic plane surgery. The average time for passage of flatus in the laparoscopy group [(3.43 ±0.72)d] was less than that in the open group [(4.10 ±0.99)d,P =0.039,P <0.05].The average time of leaving bed [(3.39 ±0.66)d] in the laparoscopy group was significantly less than that in the open group [(4.20 ±0.79)d,P =0.005,P <0.05].The mean operative time of the laparoscopy group [(160.93 ±20.91)min] was longer than that of the open group [(103.00 ±24.29)min,P =0.000,P <0.05].The average number of total lymph nodes removed of the laparoscopy group [(23.16 ±8.21)] was higher than that of the open group [(19.06 ±7.48)],but the difference was not statistically significant between the two groups (P =0.102,P >0.05).The overall postoperative complication rate of the laparoscopy group was 13.33%,which was lower than 22.50% of the open group,but the difference was not statistically significant between the two groups(P =0.268,P >0.05).Conclusion Laparoscope complete mesocolic excision for right colon cancer is safe and feasible.

ABSTRACT
PURPOSE: Early recovery of gastrointestinal motility is one of the main advantages of laparoscopic intestinal surgery. However, the reasons for this advantage are still not well known. To compare recovery of bowel motility after laparoscopic-assisted and open surgery for right colon cancer, we analyzed early clinical results, including both the gastric emptying time by using a Sitz-marker(TM) and the intraperitoneal temperature. METHODS: From January 1996 to December 1999, 80 curative right hemicolectomies, which were divided into a laparoscopic-assisted surgery group (LS) with 36 patients and an open surgery group (OS) with 44 patients, were prospectively, but not randomly, studied for recovery of bowel motility. Clinical results, such as the pain score, the time to gas passage, the time to resumption of meals the hospital stay and the gastric emptying time obtained by using a Sitz-markers(TM), were evaluated. At the beginning and the end of the operation, the intraperitoneal temperature was checked at three different points. RESULTS: In the LS and OS groups, the first flatus passed at the 3.0 and the 3.67 postoperative day (POD) and oral intake resumed at the 3.9 and the 5.2 POD, respectively (P0.05), 1.7 and 4.2 at the 3rd POD (P<0.05) and 0 and 1.1 at the 4th POD (P<0.05), respectively. No difference in intraperitoneal temperature was noted. CONCLUSIONS: We found earlier recovery of bowel function after laparoscopic surgery than after open surgery, but could not identify any relationship between bowel function and the possible parameter of intraperitoneal temperature.
