Abstract
INTRODUCTION To explore the surgical effect and gastrointestinal functional recovery of laparoscopic-guided total mesorectal excision (LGTME) in patients with rectal cancer. PATIENTS AND METHODS A total of 150 rectal cancer patients who underwent surgical treatment in our hospital from July 2022 to July 2023 were selected and randomly divided into two groups using a random number table. There were 75 cases in the control group (CG) who underwent traditional open rectal total mesorectal excision surgery and 75 cases in the experimental group (EG) who underwent LGTME. The surgical effects of the two groups were compared, and the gastrointestinal and anal functional recovery of the two groups were compared before and after treatment. RESULTS Intraoperative bleeding, incision length, time to initial feeding and time to anal exhaust in the EG were significantly lower than those in the CG ( P < 0.05). Before treatment, there was no significant difference in gastrointestinal function and anal function between the two groups ( P > 0.05). After treatment, the levels of motilin, gastrin, neuropeptide Y and basic fibroblast growth factor in the EG were significantly higher than those in the CG, with statistical significance ( P < 0.05); the maximum anal systolic pressure and resting anal sphincter pressure in the EG were significantly lower than those in the CG ( P < 0.05); the rectal sensitivity threshold volume (RSTV) and rectal maximum volume threshold in the EG were significantly higher than those in the CG ( P < 0.05). There was no significant difference in most postoperative complications between the two groups ( P > 0.05). CONCLUSION LGTME improves the surgical effects of rectal cancer patients, promotes the recovery of gastrointestinal function and has a small effect on anal function indicators, thereby reducing hospital stay.

Determining the optimal distal resection margin in rectal cancer patients by imaging of large pathological sections: An experimental study. Medicine (Baltimore) 2024; 103:e38083. [PMID: 38787988 PMCID: PMC11124751 DOI: 10.1097/md.0000000000038083] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Accepted: 04/11/2024] [Indexed: 05/26/2024] Open
Abstract
OBJECTIVE To determine the distal resection margin in sphincter-sparing surgery in patients with low rectal cancer based on imaging of large pathological sections. METHODS Patients who underwent sphincter-sparing surgery for ultralow rectal cancer at Guangxi Medical University Cancer Hospital within the period from January 2016 to March 2022 were tracked and observed. The clinical and pathological data of the patients were collected and analyzed. The EVOS fluorescence automatic cell imaging system was used for imaging large pathological sections. Follow-up patient data were acquired mainly by sending the patients letters and contacting them via phone calls, and during outpatient visits. RESULTS A total of 46 patients (25 males, 21 females) aged 27 to 86 years participated in the present study. Regarding clinical staging, there were 9, 10, 16, and 10 cases with stages I, II, III, and IV low rectal cancer, respectively. The surgical time was 273.82 ± 111.51 minutes, the blood loss was 123.78 ± 150.91 mL, the postoperative exhaust time was 3.67 ± 1.85 days, and the postoperative discharge time was 10.36 ± 5.41 days. There were 8 patients with complications, including 3 cases of pulmonary infection, 2 cases of intestinal obstruction, one case of pleural effusion, and one case of stoma necrosis. The longest and shortest distal resection margins (distances between the cutting edges and the tumor edges) were 3 cm and 1 cm, respectively. The minimum length of the extension areas of the tumor lesions in the 46 images of large pathological sections was 0.1 mm, and the maximum length was 15 mm. Among the tumor lesions, 91.30% (42/46) had an extension area length of ≤5 mm, and 97.83% (45/46) had an extension area length of ≤10 mm. The length of the extension zone was not related to clinical pathological parameters (P > .05). CONCLUSION In the vast majority of cases, the distal resection margin was at least 1 cm; thus, "No Evidence of Disease" could have been achieved. Additional high-powered randomized trials are needed to confirm the results of the present study.

Mesorectal reconstruction with pedicled greater omental transplantation to relieve low anterior resection syndrome following total intersphincteric resection in patients with ultra-low rectal cancer. BMC Surg 2023; 23:236. [PMID: 37573297 PMCID: PMC10423425 DOI: 10.1186/s12893-023-02140-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Accepted: 08/04/2023] [Indexed: 08/14/2023] Open
Abstract
BACKGROUND Total intersphincteric resection (ISR) is the ultimate anus-preserving surgery for patients with ultra-low rectal cancer (ULRC), which can result in various degrees of anorectal dysfunction. Known as low anterior resection syndrome (LARS), it seriously affects the postoperative quality of life of patients. The aim of this study was to discuss the value of mesorectal reconstruction with pedicled greater omental transplantation (PGOT) to relieve LARS following total ISR in patients with ULRC, hoping to provide new ideas and strategies for the prevention and improvement of LARS. METHODS We retrospectively analyzed hospitalization data and postoperative anorectal function of 26 ULRC patients, who were met inclusion and exclusion criteria in our center from January 2015 to February 2022. And combined with the results of anorectal manometry and rectal magnetic resonance imaging (MRI) defecography of some patients, we assessed comprehensively anorectal physiological and morphological changes of the patients after surgery, and their correlation with LARS. RESULTS In this study, 26 patients with ULRC were enrolled and divided into observation group (n = 15) and control group (n = 11) according to whether PGOT was performed. There were no significant differences in surgical results such as operative time, intraoperative blood loss and postoperative complications between the two groups (P > 0.05). Postoperative follow-up showed that patients in both groups showed severe LARS within 3 months after surgery, but from the 3rd month after surgery, LARS in both groups gradually began to decrease, especially in the observation group, which showed faster recovery and better recovery, with statistically significant difference (P < 0.001). Through anorectal manometry, the mean rectal resting pressure in the observation group was significantly lower than that in the control group (P = 0.010). In addition, the postoperative thickness of the posterior rectal mesenterium in the observation group was significantly higher than that in the control group (P = 0.001), and also higher than the preoperative level (P = 0.018). Moreover, rectal MRI defecography showed that the neo-rectum had good compliance under the matting of greater omentum, and its intestinal peristalsis was coordinated. CONCLUSIONS ULRC patients, with the help of greater omentum, coordinated their neo-rectum peristalsis after total ISR and recovery of LARS was faster and better. PGOT is expected to be an effective strategy for LARS prevention and treatment of ULRC patients after surgery and is worthy of clinical promotion.
