Project description:BackgroundLaparoscopic total mesorectal excision (TME) for rectal cancer has been proved in various studies. The minimal invasive procedure is feasible and safe which was demonstrated in many studies. However, the results of prospective, randomized studies providing valuable evidence are still not available. Compared to conventional surgery, the laparoscopic technique has short-term advantages including less pain, shorter duration of postoperative ileus, less fatigue, better pulmonary function, and less blood loss (Leung et al., Lancet 363:1187-1192, 2004; Braga et al., Dis Colon Rectum 48:217-223, 2005; Jayne et al., J Clin Oncol 25:3061-3068, 2007; Agha et al., Surg Endosc 22:2229-2237, 2008).MethodsThe autonomic nerve sparing TME technique is the gold standard in rectal cancer resection even in conventional or laparoscopic procedure. With regard of the oncological dimension, the laparoscopic TME technique is not different compared to the open procedure. However, a standardized laparoscopic step-by-step procedure may simplify the operation and can reduce operation time.ResultsThere are no studies available which compare different types of TME procedures. Most surgeons start the operation left laterally mobilizing the sigmoid colon first. In the laparoscopic technique, we recommend the medial to lateral approach starting the operation at the right side of the rectum and sigmoid colon. A nerve sparing TME technique can be performed easier, and the identification of the left ureter may be simplified. After multiple workshops and extensive discussion with national and international experts, we developed a standardized laparoscopic "10 step TME procedure." Reviewing the results of laparoscopic TME the studies do not allow firm conclusions as to the questions of whether the safety and efficacy of laparoscopic TME is equal or superior to open TME (Breukink et al. 2006). Actually, we are waiting for large prospective randomized studies comparing laparoscopic TME with the traditional open procedure (Bonjer et al., Dan Med Bull 56:89-91, 2009).ConclusionLaparoscopic TME appears to have clinically measurable short-term advantages in patients with primary resectable rectal cancer based on evidence mainly from nonrandomized studies (Breukink et al. 5). In nearly all published studies, the efficacy and technical feasibility of laparoscopic surgery for rectal cancer could be demonstrated regarding perioperative morbidity and oncological outcome. A standardized laparoscopic TME technique can be strongly recommended.

Project description:A primary goal of training is the development of one's own procedure by self-learning, which can be facilitated by laparoscopic surgery owing to its recordable system. This video demonstrates laparoscopic low anterior resection for a 56-year-old male diagnosed with synchronous S-colon cancer and rectal cancer. The surgery was performed by a second-year fellow in the colorectal division under supervision.

Project description:The aim of this study was to investigate the effect of preservation of Denonvilliers' fascia (DF) during laparoscopic resection for mid-low rectal cancer on protection of male urogenital function. Whether preservation of DF during TME is effective for protection of urogenital function is largely elusive.Seventy-four cases of male mid-low rectal cancer were included. Radical laparoscopic proctectomy was performed, containing 38 cases of preservation of DF (P-group) and 36 cases of resection of DF (R-group) intraoperatively. Intraoperative electrical nerve stimulation (INS) on pelvic autonomic nerve was performed and intravesical pressure was measured manometrically. Urinary function was evaluated by residual urine volume (RUV), International Prostatic Symptom Score (IPSS), and quality of life (QoL). Sexual function was evaluated using the International Index of Erectile Function (IIEF) scale and ejaculation function classification.Compared with performing INS on the surfaces of prostate and seminal vesicles in the R-group, INS on DF in the P-group exhibited higher increasing intravesical pressure (7.3 ± 1.5 vs 5.9 ± 2.4 cmH2O, P = 0.008). In addtion, the P-group exhibited lower RUV (34.3 ± 27.2 vs 57.1 ± 50.7 mL, P = 0.020), lower IPSS and QoL scores (7 days: 6.1 ± 2.4 vs 9.5 ± 5.9, P = 0.002 and 2.2 ± 1.1 vs 2.9 ± 1.1, P = 0.005; 1 month: 5.1 ± 2.4 vs 6.6 ± 2.2, P = 0.006 and 1.6 ± 0.7 vs 2.1 ± 0.6, P = 0.003, respectively), higher IIEF score (3 months: 10.7 ± 2.1 vs 8.9 ± 2.0, P = 0.000; 6 months: 14.8 ± 2.2 vs 12.9 ± 2.2, P = 0.001) and lower incidence of ejaculation dysfunction (3 months: 28.9% vs 52.8%, P = 0.037; 6 months: 18.4% vs 44.4%, P = 0.016) postoperatively.Preservation of DF during laparoscopic resection for selective male mid-low rectal cancer is effective for protection of urogenital function.

Project description:PurposeThis study was designed to evaluate the patterns and predictors of recurrence in patients who underwent laparoscopic resection of rectal cancer.MethodsPatients with rectal cancer receiving laparoscopic resection between April 2009 and March 2016 were retrospectively analyzed. The association of recurrence with clinicopathological characteristics was evaluated using multivariate analyses.ResultsA total of 405 consecutive patients were included in our study. Within a median follow-up time of 62 months, 77 patients (19.0%) experienced disease recurrence: 10 (2.5%) had locoregional recurrence (LR), 61 (15.1%) had distant metastasis (DM), and 6 (1.5%) developed LR and DM synchronously. The lung was the most common site of metastasis. Multivariate analyses indicated that involved circumferential resection margin (CRM) was the only independent predictor for LR (OR=13.708, 95% CI 3.478-54.026, P<0.001), whereas elevated baseline level of CA19-9 (OR=3.299, 95% CI 1.461-7.449, P=0.032), advanced pN stage (OR=2.292, 95% CI 1.177-4.462, P=0.015) and harvested lymph nodes less than 12 (OR=2.418, 95% CI 1.245-4.695, P=0.009) were independently associated with DM. Patients receiving salvage surgery showed superior 3-year survival compared with palliative treatment after relapse (90.9% vs. 20.5%; P=0.017). The estimated 5-year DFS and CSS for the entire cohort was 80.2% and 83.1%, respectively.ConclusionsDM was more common than LR after laparoscopic resection of rectal cancer, and there were several clinicopathological factors related to LR and DM. Involved CRM and suboptimal lymph node yield were adverse surgery-related factors of tumor recurrence, which should be paid more attention to during the operation.

Project description:BackgroundThe objective of this study is to clarify the relationship between demographic and surgical factors and operating time, and thus operative difficulty, in patients undergoing laparoscopic anterior resection for mid-low rectal cancer, since different studies have derived different results.MethodsThe records of patients with mid-low rectal cancer who underwent laparoscopic anterior resection were retrospectively studied. Demographic data, tumor characteristics, and pelvimetry measurements were collected and analyzed with respect to operating time, using correlation coefficient analysis, principle component analysis, and linear regression.ResultsA total of 14 patients (10 males, 4 females; 65.50 ± 7.12 years of age) were included. Demographic and tumor characteristics not correlated with operating time. Body mass index (BMI) (P = 0.001); interacetabular distance (IA) (P = 0.001); anatomical transverse distance (IP) (P = 0.008); interischial distance (IS) (P = 0.002); intertuberous distance (IT) (P = 0.005); distance between the coccyx and symphysis (CoSy) (P = 0.013); and the angle of the lower border of the symphysis pubis, upper border of symphysis pubis, and sacral promontory (angle 5) (P = 0.004) were significantly associated with operating time. The equation was:operatingtime=0.653 × BMI+0.818 × angle5-0.404 × IA-0.380 × IP-0.512 × IS-0.405×IT-0.570 × CoSy+330.8.ConclusionsTransverse diameters of the pelvis, BMI, angle 5, and CoSy played the most important role in affecting operating time. The equation can be a very useful tool for preoperative assessment.

Project description:BackgroundThe success of laparoscopic liver resection (LLR) depends on stable and full exposure of the parenchymal transection plane. We evaluated the efficacy of LLR using a silicone band retraction method for lesions in the anterolateral and posterosuperior segments.MethodsWe retrospectively analyzed 189 consecutive patients who had undergone LLR in our hospital between July 2010 and July 2020. They were divided into 2 groups according to whether LLR was performed before (conventional group; n=64) or after (silicone band group; n=125) the introduction of the silicone band retraction method.ResultsThe silicone band group demonstrated significantly less blood loss than that by the conventional group. The mean operative time and the hospital stay in the silicone band group were obviously shorter than that in the conventional group. The open conversion rate and the major complication rate were significantly lower in the silicone band group than that in the conventional group.ConclusionThe silicone band retraction method is a useful approach that results in a safe LLR.

Project description:Renal oncocytoma (RO) represents about 7% of kidney tumors. They usually behave in a benign fashion, with a slow-growth rate. Patients are often asymptomatic and the tumour is found incidentally on imaging. Due to its wide variation of presentations and multiple radiological findings it is difficult to differentiate RO from renal-cell carcinomas. Interpretation of the images in the appropriate clinical context is crucial and supports the surgeon to avoid aggressive surgical procedures in favor of a nephron-sparing approach, whenever possible. We report a case of a 71-year-old female patient with a large calcified RO which was resected laparoscopically.

Project description:BackgroundMaintaining employment for adults with cancer is important, however, little is known about the impact of surgery for rectal cancer on an individual's capacity to return to work (RTW). This study aimed to determine the impact of laparoscopic vs. open resection on RTW at 12 months.MethodsAnalyses were undertaken among participants randomized in the Australian Laparoscopic Cancer of the Rectum Trial (ALaCaRT), with work status available at baseline (presurgery), and 12 months. Multivariable logistic regression, adjusted for sociodemographic and clinical characteristics estimated the effect of surgery on RTW in any capacity, or return to preoperative work status at 12 months.ResultsAbout 228 of 449 (51%) surviving trial participants at 12 months completed work status questionnaires; mean age was 62 years, 66% males, 117 of these received laparoscopic resection (51%). Of 228, 120 were employed at baseline (90 full-time, 30 part-time). Overall RTW in 120 participants in paid work at baseline was 78% (84% laparoscopic, 70% open surgery). Those employed full-time were more likely to RTW at 12 months (OR, 3.55; 95% CI, 1.02-12.31). Those with distant metastases at baseline were less likely to RTW (OR, 0.07; 95% CI, <0.01-0.83). Laparoscopic surgery was associated with a higher rate of RTW but did not reach statistical significance (OR 2.88; 95% CI, 0.95-8.76).ConclusionsFull-time work presurgery and the presence of metastatic disease predicts RTW status at 12 months. A laparoscopic-assisted surgical approach to rectal cancer may facilitate more patients to RTW, however, larger sample sizes are likely needed to confirm this result.

Project description:To compare the short- and long-term outcomes of laparoscopic and robotic surgery for middle and low rectal cancer.This is a retrospective study on a prospectively collected database containing 111 patients who underwent minimally invasive rectal resection with total mesorectal excision (TME) with curative intent between January 2008 and December 2014 (robot, n = 53; laparoscopy, n = 58). The patients all had a diagnosis of middle and low rectal adenocarcinoma with stage?I-III disease. The median follow-up period was 37.4 mo. Perioperative results, morbidity a pathological data were evaluated and compared. The 3-year overall survival and disease-free survival rates were calculated and compared.Patients were comparable in terms of preoperative and demographic parameters. The median surgery time was 192 min for laparoscopic TME (L-TME) and 342 min for robotic TME (R-TME) (P < 0.001). There were no differences found in the rates of conversion to open surgery and morbidity. The patients who underwent laparoscopic surgery stayed in the hospital two days longer than the robotic group patients (8 d for L-TME and 6 d for R-TME, P < 0.001). The pathologic evaluation showed a higher number of harvested lymph nodes in the robotic group (18 for R-TME, 11 for L-TME, P < 0.001) and a shorter distal resection margin for laparoscopic patients (1.5 cm for L-TME, 2.5 cm for R-TME, P < 0.001). The three-year overall survival and disease-free survival rates were similar between groups.Both L-TME and R-TME achieved acceptable clinical and oncologic outcomes. The robotic technique showed some advantages in rectal surgery that should be validated by further studies.

Project description:BackgroundThe lateral intersecting margin (dog-ear) was a weak spot of the double stapled technique (DST), We designed "dog-ear" invagination anastomosis (DAIA), which could eliminate the "dog-ear" in laparoscopic anterior resection.Patients and methodsA total of 202 patients underwent elective curative LLAR + DST (n = 143) or LLAR + DAIA (n = 59) were enrolled in the study. Propensity score matching (PSM) was used to minimize the adverse effects. The clinical data between LLAR + DST and LLAR + DAIA was compared, and the effect of factors on overall survival (OS) and disease-free survival (DFS) was analyzed.ResultsAfter PSM, 53 pairs of the LLRA + DST and LLRA + DAIA patients were enrolled in the study. The LLRA + DAIA group has a higher level (3.50 ± 1.03 vs. 2.87 ± 1.10, P = 0.01) of the anastomosis than that of the LLRA + DST group. Patients in LLAR + DAIA group have a lower incidence of protecting loop ileostomy compared to LLAR + DST group (20.75% vs. 5.66%, P < 0.05). The LLRA + DAIA patients presented better rates of LARS compare to LLRA + DST patients at 6 months (major LARS 37.74% (n = 20) vs. 67.93% (n = 36); P = 0.007) and 12 months (major LARS 13.21% (n = 7) vs. 20.37% (n = 11); P = 0.03) after surgery. The OS and DFS rates were similar (P > 0.05).ConclusionLaparoscopic low anterior resection with "dog-ear" invagination anastomosis technique are well-established procedures for patients with low rectal cancer. "Dog-ear" invagination anastomosis technique may reduce the incidence of protecting loop ileostomy and significantly affect LARS score, and demonstrate a positive impact on the quality of life after surgery.
