Abstract
BACKGROUND Multiple authors have described an initial learning curve (LC) for robotic proctectomy (RP), but there is scant literature regarding continued technical progression beyond this stage. Total operating time is the most commonly used metric to measure proficiency. Our goal was to examine RP experience after the initial LC looking for evidence of further technical progression. METHODS We reviewed our robotic surgery database for a single surgeon during operations 100 through 550 to identify 83 RPs for tumor. These were divided into quartiles by series order, indicating surgeon experience level over time. Demographics and outcomes were compared among the groups. We defined percent console time (PCT) as a new metric. PCT was defined as console time divided by total operative time (TOT). RESULTS From March 2014 through March 2019, 450 robotic colorectal operations were performed, including 83 RPs for polyp or cancer. No significant differences were found among the quartiles in regard to demographics, tumor features, hospital stay, conversions, or readmissions. As experience was gained, there were significant increases in intracorporeal anastomosis (ICA), TOT, and PCT. Complications decreased with experience. Number of lymph nodes in the specimen increased. On multivariate analysis, later experience group, body mass index ≥30, and ICA were associated with increased PCT. DISCUSSION ICA became a routine part of RP after the initial LC, with increases in TOT and PCT. Number of lymph nodes increased and number and severity of complications decreased with experience. Increased PCT may indicate increased expertise during RP.

Abstract
Natural orifice surgery has been used with increasing frequency in colon surgeries since the early 2000's. Our aim was to examine the patients retrospectively who underwent Natural Orifice Specimen Excision (NOSE) following laparoscopic colorectal resection. A total of 102 patients 2013 and 2018 were evaluated. The demographic characteristics, intra-operative and post-operative findings, pathology results, pain, incontinence, sexual dysfunction and cosmetic scores were examined. Mean age was 57.0 ± 14 and 52 of them (51%) were female. Specimen extraction was transanal in 72 (70%) (eventration technique in 10 patients) and transvaginal in the remaining 30 patients. The mean operating time was 272 ± 108 (median 240, range 120-540) minutes, and the mean blood loss was 92 ± 87 ml (median 54, range 5-400). The mean hospital stay was 7.0 ± 4.7 days (median 6, range 3-30). The main pain scores (visual analog score) on days 1-2-3 were 3.9 ± 2.0 (median 4, range 1-9), 3.1 ± 1.7 (median 3, range 0-8), 1.9 ± 1.5 (median 1.5, range 0-7), respectively. The mean cosmetic scores were 9.1 ± 1.5 (median 10, range 3-10). The median Wexner Incontinence score was 0 (0-9). Hospital mortality was 1% and unrelated with the NOSE. The 5-year overall survival and disease-free survival rates for cancer patients were 77.2-63.3%, respectively. NOSE has advantages in laparoscopic colorectal resections. It increases patient comfort and decreases incision related complications. CLINICAL TRIALS: www.clinicaltrials.gov (NCT04394988).

Abstract
Purpose Total laparoscopic anterior resection (tLAR) has been gradually applied in the treatment of rectal cancer (RC). This study aims to develop a scoring system to predict the surgical difficulty of tLAR. Methods RC patients treated with tLAR were collected. The blood loss and duration of excision (BLADE) scoring system was built to assess the surgical difficulty by using restricted cubic spline regression. Multivariate logistic regression was used to evaluate the effect of the BLADE score on postoperative complications. The random forest (RF) algorithm was used to establish a preoperative predictive model for the BLADE score. Results A total of 1,994 RC patients were randomly selected for the training set and the test set, and 325 RC patients were identified as the external validation set. The BLADE score, which was built based on the thresholds of blood loss (60 ml) and duration of surgical excision (165 min), was the most important risk factor for postoperative complications. The areas under the curve of the predictive RF model were 0.786 in the training set, 0.640 in the test set, and 0.665 in the external validation set. Conclusion This preoperative predictive model for the BLADE score presents clinical feasibility and reliability in identifying the candidates to receive tLAR and in making surgical plans for RC patients.

Abstract
BACKGROUND The conventional laparoscopic colorectal surgery requires four or more ports to accomplish the laparoscopic dissection, and a mini-laparotomy to remove the specimen, which is a main cause of postoperative pain and incision complications, and compromise the cosmetic results. Reduced port surgery and natural orifice specimen extraction (NOSE) surgery hold the promise to overcome these drawbacks. This study planned to compare peri-operative outcomes of patients with rectal-sigmoid cancer undergoing three-port laparoscopic anterior resection with NOSE (three-port NOSE LAR) to those of patients receiving conventional LAR. METHODS Twenty-five patients with rectal-sigmoid cancer underwent three-port NOSE LAR between December 2018 and October 2020. For comparison, 50 patients with rectal-sigmoid cancer underwent conventional LAR in the same period were matched. The peri-operative outcomes were compared. RESULTS Operating time of three-port NOSE group was slightly longer than that of conventional group (135 min vs. 121 min, p = .147). The incision length of three-port NOSE group was shorter than that of conventional group (2.9 cm vs. 7.4 cm, p = .000). Complication rates in three-port NOSE group and conventional group were similar (12.0% vs. 20.0%, p = .524). The tumor size was smaller in three-port NOSE group than the conventional group (2.1 cm vs. 3.5 cm, p = .000). Pain score was lower in three-port NOSE group than the conventional group at postoperative day 1 (1.6 vs. 3.0, p = 0.045) and day 2 (0.2 vs. 2.1, p = .003). The BIQ score was significantly higher in the three-port NOSE group compared to the conventional group (42.9 ± 3.5 vs. 38.2 ± 2.5, p = .002). CONCLUSIONS Three-port NOSE LAR for rectal-sigmoid cancer is feasible and provides similar peri-operative outcomes compared to conventional LAR. It reduces postoperative pain and produces better cosmesis.

Abstract
BACKGROUND AND AIM The goal of this study was to develop a preoperative nomogram for predicting the feasibility of trans-anal natural orifice specimen extraction (NOSE) for rectal cancer. METHODS The analysis included 201 patients who underwent trans-anal NOSE and 457 patients who failed to undergo trans-anal NOSE in Shanghai East Hospital. The data collected included age, gender, body mass index, presence of tumor obstruction, distance from anal verge; maximum tumor diameter and anteroposterior thickness of mesorectum (AP) measured by magnetic resonance imaging; interspinous diameter, intertuberous diameter (IT), anteroposterior diameter of the inlet (API), anteroposterior diameter of the midplane, anteroposterior diameter of the outlet (APO), sacral length and pelvic depth (PD) measured by computed tomography. RESULTS The multivariate analysis suggested that a lower body mass index (P < 0.001), no tumor obstruction (P = 0.005), a shorter distance from anal verge (P < 0.001), a smaller tumor size (P < 0.001), a thinner AP (P < 0.001), a wider and shallower bony pelvis (API/PD, P < 0.001), and a wider and shorter pelvic outlet (IT/APO, P < 0.001) were significantly associated with an increased probability of trans-anal NOSE. Successful NOSE patients had a decreased time to liquid intake (P < 0.001), a shorter postoperative hospital stay (P < 0.001), and fewer wound infections (P = 0.045). No significant difference in the rate of mortality or recurrence was observed. The nomogram model presented an area under the receiver operating characteristic curve of 0.81 (95% CI, 0.78 to 0.85) and good calibration. CONCLUSION We developed a nomogram model that has some predicative value for the feasibility of laparoscopic rectal resection with trans-anal NOSE, utilizing clinical and radiologic parameters, available in most institutions.

A Novel Method of Natural Orifice Specimen Extraction Surgery (NOSES) during Laparoscopic Anterior Resection for Rectal Cancer. Gastroenterol Res Pract 2021; 2021:6610737. [PMID: 33574839 PMCID: PMC7857920 DOI: 10.1155/2021/6610737] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/07/2020] [Revised: 12/28/2020] [Accepted: 01/12/2021] [Indexed: 11/17/2022] Open
Abstract
We propose a modification to the reconstruction method of natural orifice specimen extraction surgery (NOSES) during laparoscopic anterior resection (LAR) for rectal cancer (RC) and evaluated its feasibility and short-term safety by comparing surgical and postoperative outcomes with those of conventional LAR. Twenty patients with RC underwent "double-purse" NOSES-LAR from October 2017 to June 2018. Data of clinicopathological characteristics, surgical and postoperative outcomes, and follow-up findings in NOSES-LAR cases were collected and retrospectively compared with those of conventional LAR to clarify the clinical benefits. The median postoperative hospital stay was lower in the double-purse NOSES group than the conventional group (6.6 vs. 7.1 days, respectively). In the conventional group, anastomotic leakage and incision site infection occurred in one patient each. In contrast, there were no complications in the double-purse group. There were no significant differences in blood loss, surgical duration, and time of the first flatus between the two groups. Additionally, "double-purse" NOSES-LAR was more economical than the conventional LAR. "Double-purse" NOSES-LAR is a safe, feasible, and minimally invasive promising procedure for LAR of RC with faster recovery, while requiring less surgical skills and lower clinical costs.

Abstract
BACKGROUND Compared to traditional open surgery, laparoscopic surgery has become a standard approach for colorectal cancer due to its great superiorities including less postoperative pain, a shorter hospital stay, and better quality of life. In 2007, Whiteford et al reported the first natural orifice trans-anal endoscopic surgery (NOTES) sigmoidectomy using transanal endoscopic microsurgery. To date, all cases of NOTES colorectal resection have included a hybrid laparoscopic approach with the use of established rigid platforms.
AIM To introduce a novel technique of peroral external traction-assisted transanal NOTES rectosigmoidectomy followed by intracorporeal colorectal end-to-end anastomosis by using only currently available and flexible endoscopic instrumentation in a live porcine model.
METHODS Three female pigs weighing 25-30 kg underwent NOTES rectosigmoid resection. After preoperative work-up and bowel preparation, general anesthesia combined with endotracheal intubation was achieved. One dual-channel therapeutic endoscope was used. Carbon dioxide insufflation was performed during the operation. The procedure of trans-anal NOTES rectosigmoidectomy included the following eight steps: (1) The rectosigmoid colon was tattooed with India ink by submucosal injection; (2) Creation of gastrostomy by directed submucosal tunneling; (3) Peroral external traction using endoloop ligation; (4) Creation of rectostomy on the anterior rectal wall by directed 3 cm submucosal tunneling; (5) Peroral external traction-assisted dissection of the left side of the colon; (6) Trans-anal rectosigmoid specimen transection, where an anvil was inserted into the proximal segment after purse-string suturing; (7) Intracorporeal colorectal end-to-end anastomosis using a circular stapler by a single stapling technique; and (8) Closure of gastrostomy using endoscopic clips. All animals were euthanized immediately after the procedure, abdominal exploration was performed, and the air-under-water leak test was carried out.
RESULTS The procedure was completed in all three animals, with the operation time ranging from 193 min to 259 min. Neither major intraoperative complications nor hemodynamic instability occurred during the operation. The length of the resected specimen ranged from 7 cm to 13 cm. With the assistance of a trans-umbilical rigid grasper, intracorporeal colorectal, tension-free, end-to-end anastomosis was achieved in the three animals.
CONCLUSION Peroral traction-assisted transanal NOTES rectosigmoidectomy followed by intracorporeal colorectal end-to-end anastomosis is technically feasible and reproducible in an animal model and is worthy of further improvements.

Clinical outcomes and prognostic factors of robotic assisted rectal cancer resection alone versus robotic rectal cancer resection with natural orifice extraction: a matched analysis. Sci Rep 2020; 10:12848. [PMID: 32733103 PMCID: PMC7392890 DOI: 10.1038/s41598-020-69830-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2020] [Accepted: 07/20/2020] [Indexed: 12/14/2022] Open
Abstract
Robotic rectal cancer resection with natural orifice extraction is a recently developed minimally invasive surgery used in the treatment of patients with rectal cancer. However, its safety and feasibility remain undiscussed and controversial. This study reported the clinical outcomes and prognostic factors pertaining to traditional robotic assisted rectal cancer resection alone against that of robotic rectal cancer resection with natural orifice extraction to provide a discussion on this issue. 49 patients who underwent robotic rectal cancer resection with natural orifice extraction and 49 matched patients who underwent conventional robotic assisted rectal cancer resection were systematically analyzed in this study. Regarding the baseline characteristics, after matching, no significant differences were observed between the natural orifice specimen extraction (NOSE) group and the robotic assisted rectal cancer resection (RARC) group. Patients in the NOSE group had a reduced visual analog scale (p < 0.001), passed flatus more quickly (p = 0.002) and suffered less surgical stress than those in the RARC group. Moreover, 4 complications were observed in the NOSE group and 7 complications in the RARC group with no significant difference (p = 0.337) in terms of complications. The two groups had a similar survival outcomes, where the 3-year overall survival (p = 0.738) and 3-year progression-free survival (p = 0.986) were all comparable between the two groups. Histological differentiation and T stage could be regarded as independent prognostic factors for 3-year overall survival and 3-year progression-free survival. Robotic rectal cancer resection with natural orifice extraction is a safe and feasible minimally invasive surgery for patients suffering from rectal cancer as it encompasses considerable several advantages. Histological differentiation and T stage may serve as independent prognostic factors for 3-year overall survival and 3-year progression-free survival.

Abstract
BACKGROUND Colorectal cancer resection surgery with transvaginal specimen extraction is becoming increasingly accepted and used by surgeons. However, few publications on robotic anterior sigmoid colon and rectal cancer resection with transvaginal specimen extraction (TVSE) have been reported, and a clinical outcome comparison between conventional robotic minilaparotomy (LAP) and transvaginal specimen extraction in anterior sigmoid colon and rectal cancer resection has not been performed. The current study compared the short- and long-term outcomes of TVSE and LAP for sigmoid colon cancer and rectal cancer in a mono-institution. METHODS From December 2014 to October 2018, 45 patients who underwent TVSE and 45 patients who underwent LAP matched by tumor location, tumor stage, body mass index (BMI), American Society of Anesthesiologists (ASA) classification, gender, and age at the same period were included in the current study. The short- and long-term outcomes of TVSE and LAP were discussed. RESULTS No significant differences were found in patient characteristics. For the short-term outcomes, the operative time in the TVSE group was longer than that in the LAP group, and the postoperative pain and additional analgesia were lower in the TVSE group. Patients in the TVSE group required slightly less time to pass first flatus. There were no significant differences in overall complications, time to regular diet, length of hospital stay after surgery, estimated blood loss, or pathological outcomes. For long-term outcomes, the 3-year overall survival (94.9% vs. 91.7%, p = 0.702) and 3-year disease-free survival (88.4% vs. 86.2%, p = 0.758) were comparable between the two groups. CONCLUSION The robotic TVSE is safe and feasible in selected sigmoid/upper rectal cancer patients with tumor diameter < 5 cm. This approach has slightly better short-term outcomes in terms of less postoperative pain and less analgesic requirements without any significant difference in long-term outcomes.

Abstract
Background The transvaginal natural orifice specimen extraction (NOSE) approach for right-side colon surgery has been proven to exhibit favorable short-term outcomes. However, thus far, no study has reported the advantages of transrectal NOSE for right-side colon surgery. The aim of this study was to compare the technical feasibility, safety, and short-term outcomes of minimally invasive right hemicolectomy using the transrectal NOSE method and those of conventional mini-laparotomy specimen extraction. Methods A study was conducted on consecutive patients who had minimally invasive right hemicolectomy either for malignancy or benign disease at Chang Gung Memorial Hospital, Linkou, Taiwan, between January 2017 and December 2018. The patients were divided into two groups: conventional surgery with specimen extraction using mini-laparotomy and NOSE surgery. Surgical outcomes, including complications, postoperative short-term recovery, and pain intensity, were analyzed. Results We enrolled 297 patients (151 males, mean age 64.9 ± 12.8 years) who had minimally invasive right hemicolectomy. Of these 297 patients, 272 patients had conventional surgery with specimen extraction through mini-laparotomy and 25 patients had NOSE surgery (23 transrectal, 2 transvaginal). The diagnosis of colon disease did not differ significantly between the conventional and NOSE groups. Postoperative morbidity and mortality rates were comparable. The postoperative hospital stay was significantly (p = 0.004) shorter in the NOSE group (median 5 days, range 3–17 days) than in the conventional group (median 7 days, range 3–45 days). Postoperative pain was significantly (p = 0.026 on postoperative day 1 and p = 0.002 on postoperative day 2) greater in the conventional group than in the NOSE group. Conclusions NOSE was associated with acceptable short-term surgical outcomes that were comparable to those of conventional surgery. NOSE results in less postoperative wound pain and a shorter hospital stay than conventional surgery. Larger studies are needed

Factors influencing the application of transrectal natural orifice specimen extraction performed laparoscopically for colorectal cancer: A retrospective study. Asian J Surg 2020; 44:164-168. [PMID: 32513636 DOI: 10.1016/j.asjsur.2020.04.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2020] [Revised: 04/22/2020] [Accepted: 04/30/2020] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND A few factors influence the feasibility of transrectal natural orifice specimen extraction (NOSE) surgery for colorectal cancers. However, little is known about the underlying factors of NOSE surgery. METHODS Consecutive patients with rectal and sigmoid colon cancers treated laparoscopically between January 2014 and April 2017 were enrolled in this study. The transrectal NOSE performed laparoscopically was the first choice of all patients. When NOSE failed, the specimen was removed through a midline abdominal wall incision. Univariate and multivariate logistic regression analyses were performed to identify challenging factors influencing the intraoperative specimen extraction. RESULTS Overall, 412 consecutive patients were included. NOSE performed laparoscopically was successful in 278 patients (75.5%) and unsuccessful in 90 patients (24.5%). The multivariate analyses indicated that body mass index (BMI; odds ratio [OR] = 3.510, 95% confidence interval [CI]: 1.333-9.243, p = 0.011), mesenteric thickness (OR = 1.069, 95% CI: 1.032-1.107, p < 0.001), maximum tumor diameter (OR = 2.827, 95% CI: 1.094-7.302, p = 0.032), and tumor T stage (OR = 2.831, 95% CI: 1.258-6.369, p = 0.012) were the factors influencing the feasibility of NOSE surgery. CONCLUSION A successful transrectal NOSE surgery was associated with a lower BMI, thinner mesentery, lesser tumor diameter, and earlier tumor T stage.

Abstract
BACKGROUND In the present paper, we introduce our experience with the novel method during laparoscopic anterior resection of upper rectal or sigmoid colon cancer by transrectal natural orifice specimen extraction (NOSE). METHODS A prospective randomized controlled trial was performed from June 2016 to May 2019. Patients with upper rectal or sigmoid colon cancer were randomized in a 1:1 ratio to the NOSE group and the non-NOSE group. Preoperative and postoperative clinical variables were analyzed and compared between groups. Postoperative pain was analyzed utilizing a visual analog scale. Postoperative overall survival was analyzed using a Kaplan-Meier curve. RESULTS A total of 276 patients were enrolled, of whom 254 were randomly divided into the NOSE group (n = 122) and the conventional laparoscopic group (n = 119). NOSE failed in 22 cases, which were converted to transabdominal specimen extraction. Intention-to-treat analysis was performed, and these 22 cases were included in the NOSE group. The incidence of postoperative complications was significantly lower in the NOSE group (11/122, 9%) than in the non-NOSE group (25/119, 21%). The NOSE group had a longer operation time, less blood loss, and a lower postoperative visual analog scale score than the non-NOSE group. The time for intestinal function recovery (ventilation) and the length of hospital stay were significantly longer in the non-NOSE group. The Kaplan-Meier survival curve showed no statistically significant difference in the disease-free survival rate between the NOSE group and the non-NOSE group. CONCLUSIONS The novel NOSE method is safe and feasible to use in patients having colorectal cancer. Compared with traditional laparoscopic surgery, the postoperative complication rates of NOSE surgery were lower with an improved short-term clinical recovery.

Abstract
BACKGROUND Low anterior resections are increasingly performed laparoscopically for rectal cancer. Recently, natural orifice specimen extraction surgery (NOSES) has been reported as an alternative approach without additional incisions or extensions. In this study, we aimed to evaluate the safety and feasibility of NOSES by comparing the short-term outcomes with those of conventional laparoscopic resection (CLR) in a multicenter retrospective study from China and Russia. METHODS The retrospective multicenter study was conducted at three centers between January 2015 and December 2017. Relevant collected data included patient demographics, operative parameters, and postoperative complications. All procedures were performed using either a NOSES or a CLR approach. RESULTS The data of a total of 768 consecutive patients with rectal cancer were retrospectively analyzed, including 412 CLR and 356 NOSES cases. The two groups were comparable for all demographics and characteristics except for the median tumor size (P = 0.038). No difference was found in the operative time and number of retrieved lymph nodes. Intraoperative complications and positive resection margins were nil in both groups. No difference was found in the time to first flatus (P = 0.150), time to first defecation (P = 0.084), length of postoperative hospital stay (P = 0.152), anastomotic leakage (P = 0.377), and intra-abdominal abscess (P = NA). The CLR group but not the NOSES group had incisional hernia or wound infection events, although the difference between groups was not significant (P = 0.253). CONCLUSIONS The NOSES procedure is a well-established strategy and may be considered as an alternative procedure to CLR for rectal cancer. However, the long-term benefits of this approach require further evaluation.

Abstract
Background: Few studies have assessed the short- and long-term outcomes of laparoscopically assisted natural orifice specimen extraction (NOSE) in patients with sigmoid colon and rectal tumors. We investigated the short- and long-term outcomes of patients undergoing laparoscopic-assisted NOSE for tumors of the sigmoid colon and rectum. Methods: Ninety-eight patients with sigmoid colon and rectal tumors undergoing laparoscopic-assisted NOSE were included. The tumor was classified according to its distance from the anal verge: Group 1 (15-30 cm), Group 2 (5-15 cm), and Group 3 (≤5 cm). In Group 1 patients, a laparoscopic surgical specimen collection bag was used as a special transrectal device. In Group 2 patients, transanal endoscopic microsurgery device and specimen collection bag were used. In Group 3 patients, a Lone-Star retractor was used. The demographic characteristics and intra- and postoperative outcomes were measured. Results: In Group 1, 1 patient had respiratory disease and 1 had enterocolitis as short-term postoperative complications. One patient showed intestinal obstruction as a long-term postoperative complication. In Group 2, 2 patients had an ileus, 1 had an anastomotic leak, 2 had urinary retention, and 1 had respiratory disease as short-term complications. Only one patient had a long-term complication: anastomotic stenosis. In Group 3, short-term complications were present in 3 patients: 1 had hemorrhage, 1 had urinary retention, and 1 had respiratory disease. Long-term complications included one case of anastomotic stenosis and one of intestinal obstruction. Conclusions: NOSE is safe and cosmetically and theoretically superior to conventional laparoscopy when different devices are used according to the tumor's location.

Abstract
Over the past 30 years, colorectal surgery has evolved to include minimally invasive surgical techniques. Minimally invasive surgery is associated with reduced postoperative pain, reduced wound complications, earlier return of bowel function, and possibly shorter length of hospital stay. These benefits have been attributed to a reduction in operative trauma compared to open surgery. The need to extract the specimen in colorectal operations through a “mini-laparotomy” can negate many of the advantages of minimally invasive surgery. Natural orifice specimen extraction (NOSE) is the opening of a hollow viscus that already communicates with the outside world, such as the vagina or distal gastrointestinal tract, in order to remove a specimen. The premise of this technique is to reduce the trauma required to remove the specimen with the expectation that this may improve outcomes. Reduction in postoperative analgesic use, quicker return of bowel function, and shorter length of hospital stay have been observed in colorectal operations with NOSE compared to conventional specimen extraction. While the feasibility of NOSE has been demonstrated in colorectal surgery, failures of this technique have also been described. Selection of patients who can successfully undergo NOSE needs further investigation. This review aims to guide surgeons in appropriately selecting patients for NOSE in colorectal surgery. Patient and specimen characteristics are reviewed in order to define patient populations in which NOSE is likely to be successful. Randomized trials comparing NOSE to conventional specimen extraction in colorectal surgery tend to enroll patients with favorable characteristics (body mass index <30, American Society of Anesthesiologists class ≤3, specimen diameter <6.5 cm) and demonstrate improved outcomes. Adopters of NOSE should restrict using this technique to the populations in which feasibility has been defined in the literature. Wider application to other populations, particularly patients with body mass index >30 and those with significant comorbidities, requires further study.

Abstract
BACKGROUND Full laparoscopic left colectomy with transrectal specimen extraction is proposed as an improvement of the minimally invasive surgical technique. This paper reviews in detail the current status of left-sided colectomy and upper rectum resection with transrectal specimen extraction. METHODS A systematic review was performed of all types of publications on colorectal resection with natural orifice specimen extraction (NOSE). We only included studies reporting on left colectomy, sigmoidectomy, and high anterior resection with transrectal specimen extraction (TRSE), excluding transanal (TASE), transvaginal, or transcolonic specimen extraction. Surgical techniques, patient characteristics, and outcomes were reviewed in detail. RESULTS Thirty-five papers reported on TRSE (2 randomized clinical trials, 7 case-matched series, 19 case series, 5 case reports, and 2 articles on surgical technique). We found a wide variety of innovative anastomotic and specimen extraction techniques. After excluding duplicates and papers reporting mixed TRSE and TASE results, outcomes in patients undergoing TRSE from 23 publications showed a conversion rate to conventional laparoscopy of 3.7% (21/559), overall morbidity 9.5% (53/559) [major in 2.9% (16/559), intra-abdominal infection in 2.1% (12/559)]. No mortality was reported. Postoperative anal incontinence was rarely reported. Several studies showed a decrease in postoperative pain and some in length of hospital stay. CONCLUSIONS Colectomy with TRSE is feasible and seems safe in selected patients. Reported outcomes seem in general similar to conventional laparoscopic colectomy with a possible benefit in postoperative pain and length of hospital stay. Obvious selection bias and lack of high quality trials do not allow firm conclusions to be drawn.

Abstract
PURPOSE To date, no data have been available to inform which cases are appropriate for natural orifice specimen extraction (NOSE) after laparoscopic colorectal resections (LCRRs). Our aim was to evaluate the success rate and the factors affecting the failure in patients who were scheduled for NOSE after LCRRs. METHODS Seventy-two consecutive cases that were intended for NOSE after LCRR were enrolled. The transanal route was always chosen as the first option, and when it failed, the transvaginal route was tried in female patients. If both failed, the specimen was judged as unsuitable for NOSE and removed through an abdominal wall incision. Demographic data, surgical indications, resection localization, implemented procedures, incision sites, specimen extraction methods, specimen sizes, and failures of NOSE were recorded. RESULTS A total of 349 colorectal resections (240 open and 109 laparoscopic) in a 3-year period were examined. The subset of 72 consecutive patients who met the criteria were analyzed. Five cases required a conversion to open surgery during resections. In the remaining 67 patients, NOSE after LCRR was successful in 49 cases (73.1%) but failed in 18 (26.9%). Specimens were extracted from transanal and transvaginal routes in 37 (75.5%) and 12 (24.5%) patients, respectively. The failure rate of NOSE after LCRR was higher in males, in colonic lesions, and in large-sized tumors. The mean sizes of transanal and transvaginal extracted specimens were 3.5 ± 3.1 and 5.4 ± 1.4 cm, respectively (p < 0.05). The mean size of the tumors in the failed cases was 6.5 ± 4.2 cm (p < 0.05). CONCLUSIONS Approximately 2/3 of the unselected LCRRs were suitable for NOSE. The success rate increased with female gender, small-sized tumors, and rectal resections.
