Abstract
PURPOSE Since the introduction of robotic surgery, robots for colorectal cancer have replaced laparoscopic surgery, and a single-port robot (SPR) platform has been launched and is being used to treat patients. We analyzed the learning curve and initial complications of using an SPR platform in colorectal cancer surgery. METHODS We reviewed 39 patients who underwent SPR colectomy from April to October 2019. All surgeries were performed by the same surgeon using an SPR device. A learning curve was generated using the cumulative sum methodology to assess changes in total operation time, docking time, and surgeon console time. We grouped the patients into 3 groups according to the time period: the first 11 were phase 1, the next 11 were phase 2, and the last 17 were phase 3. RESULTS The mean age of the patients was 61.28±13.03 years, and they had a mean body mass index of 23.79±2.86 kg/m2. Among the patients, 23 (59.0%) were male, and 16 (41.0%) were female. The average operation time was 186.59±51.30 minutes, the average surgeon console time was 95.49±35.33 minutes, and the average docking time (time from skin incision to robot docking) was 14.87±10.38 minutes. The surgeon console time differed significantly among the different phases (P<0.001). Complications occurred in 8 patients: 2 ileus, 2 postoperation hemoglobin changes, 3 urinary retentions, and 1 complicated fluid collection. CONCLUSION In our experience, the learning curve for SPR colectomy was achieved after the 18th case.

[PMID: 35317355 PMCID: PMC8914525 DOI: 10.4174/astr.2022.102.3.159] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Revised: 12/31/2021] [Accepted: 01/28/2022] [Indexed: 12/04/2022] Open
Abstract
Purpose We analyzed the learning curve of single-port robotic (SPR)-assisted rectal cancer surgery. Methods Fifty-seven consecutive SPR-assisted rectal cancer surgery cases performed by the same surgeon were considered in surgical interventions for rectal cancer. Total operation time (OT), docking time (DT), and surgeon console time (SCT) measured during surgery were used to parametrize the learning curve. The parameters representing the learning curve were evaluated using the cumulative sum (CUSUM). Results The mean value of total OT was 241.8 ± 91.7 minutes, the mean value of DT was 20.6 ± 19.1 minutes, and the mean value of SCT was 135.9 ± 66.7 minutes. The learning curve was divided into phase 1 (initial 16 cases), phase 2 (second 16 cases), and phase 3 (subsequent 25 cases). The peak on the CUSUM graph occurred in the 21st case. The longest OT among phases was in phase 2. Complications were most frequent in phase 2. However, complications of Clavien-Dindo (CD) grade IIIb were most frequent in phase 3 with 2 patients. The most common complications were fluid collection and urinary retention (7 patients each). Complications of CD grade IIIb required one stomal revision due to stoma obstruction and one irrigation and loop ileostomy due to anastomosis leakage. Conclusion Improvement in surgical performance of SPR assisted rectal cancer operation was achieved after 21 cases. The three phases identified in the cumulative sum analysis showed a significant decrease in operative time after the middle stage of the learning curve without an increase in the complication rate.

World J Gastrointest Surg 2021; 13:597-619. [PMID: 34194617 PMCID: PMC8223707 DOI: 10.4240/wjgs.v13.i6.597] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2021] [Revised: 05/04/2021] [Accepted: 05/18/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The benefits of laparoscopic approach for right colectomy have been well established. However, the technical difficulty to construct the intra-corporeal anastomosis is still cumbersome.
AIM To analyze the results of 3D and 2D laparoscopic right colectomy and to compare it to the published series through a systematic review and meta-analysis.
METHODS A retrospective study with propensity score matching analysis of patients undergoing laparoscopic right colectomy at Umbria2 Hospitals from January 2014 to March 2020 was performed. A systematic review was accomplished comparing 2D and 3D right colectomy.
RESULTS In the personal series 47 patients of the 2D group were matched to 47 patients of the 3D group. The 3D group showed a favorable trend in terms of mean operative time (170.7 ± 32.9 min vs 183.8 ± 35.4 min; P = 0.053) and a significant lower anastomotic time (16.9 ± 2.3 min vs 19.6 ± 2.9 min, P < 0.001). The complete mesocolic excision (CME) subgroups analysis showed a shorter anastomotic time (16.5 ± 1.8 min vs 19.9 ± 3.0 min; P < 0.001) and operative time (175.0 ± 38.5 min vs 193.7 ± 37.1 min; P = 0.063) in the 3D group. Six studies and our series were included in the meta-analysis with 551 patients (2D group: 291; 3D group: 260).The pooled analysis demonstrated a significant difference in favour of the 3D group regarding the operative time (P < 0.001) and the anastomotic time (P < 0.001) while no differences were identified between groups in terms of blood loss (P = 0.827), LNH yield (P = 0.243), time to first flatus (P = 0.333), postoperative complications (P = 0.718) and length of stay (P = 0.835).
CONCLUSION The meta-analysis results showed that 3D laparoscopic right colectomy shortens operative and anastomotic time without affecting the standard lymphadenectomy. In our series, the advantage of the 3D system becomes evident when CME and/or more complex associated procedure are requested significantly reducing both the total operative and the anastomotic time.

Abstract
BACKGROUND Robotic surgery has advantages in terms of the ergonomic design and expectations of shortening the learning curve, which may reduce the number of patients with adverse outcomes during a surgeon's learning period. We investigated the differences in the learning curves of robotic surgery and clinical outcomes for rectal cancer among surgeons with differences in their experiences of laparoscopic rectal cancer surgery. METHODS Patients who underwent robotic surgery for colorectal cancer were reviewed retrospectively. Patients were divided into five groups by surgeons, and their clinical outcomes were analyzed. The learning curve of each surgeon with different volumes of laparoscopic experience was analyzed using the cumulative sum technique (CUSUM) for operation times, surgical failure (open conversion or anastomosis-related complications), and local failure (positive resection margins or local recurrence within 1 year). RESULTS A total of 662 patients who underwent robotic low anterior resection (LAR) for rectal cancer were included in the analysis. Number of laparoscopic LAR cases performed by surgeon A, B, C, D, and E prior to their first case of robotic surgery were 403, 40, 15, 5, and 0 cases, respectively. Based on CUSUM for operation time, surgeon A, B, C, D, and E's learning curve periods were 110, 39, 114, 55, and 23 cases, respectively. There were no significant differences in the surgical and oncological outcomes after robotic LAR among the surgeons. CONCLUSIONS This study demonstrated the limited impact of laparoscopic surgical experience on the learning curve of robotic rectal cancer surgery, which was greater than previously reported curves.

Abstract
BACKGROUND Single-incision laparoscopic right hemicolectomy (SILS) has been promoted in clinic since 2008, but a systematic review of comparing SILS and traditional laparoscopic right hemicolectomy (TLS) with long-term follow-up is rare. Here, in this study, comparison of SILS and TLS with long-term follow-up was evaluated by a meta-analysis method. METHODS All studies about SILS and TLS for right hemicolectomy from 2010 to 2018 were searched from databases including Medline, Embase, Cochrane Library, and Wanfang. Operation index, recovery, and midterm follow-up data were evaluated by fixed-effects models, random-effects models, and Begg test. RESULTS We collected 22 studies with 2218 patients. SILS groups contained 1038 (46.7%) patients, and 1180 (53.3%) patients were observed in the TLS group. Patients' baseline data were similar in the 2 groups. Compared with TLS, SILS had shorter operation duration [standardized mean difference (SMD): -0.35, 95% confidence interval (CI): -0.61 to -0.08, P<0.001, χ=49.40], shorter hospitalization time (SMD: -0.27, 95% CI: -0.37 to -0.16, P<0.001, χ=9.17), slightly less blood loss (SMD: -0.23, 95% CI: -0.36 to -0.10; P<0.001; χ=5.36), and smaller incision length (SMD: -2.19, 95% CI: -3.66 to -0.71, P<0.001; χ=316.1). No statistical differences were observed in other figures. CONCLUSION SILS is more convenient and has better efficacy than TLS and could provide a promising surgical approach for right colon diseases.

Abstract
BACKGROUND Laparoscopic right hemicolectomy (LRHC) is increasingly performed for the treatment of right colon disease. Nevertheless, standardization of the surgical technique regarding the performance of intracorporeal (IC) or extracorporeal (EC) anastomosis is lacking. The purpose of this study was to compare short-term postoperative outcomes in patients who had laparoscopic right colectomy either with IC or EC. METHODS This was a retrospective, non-randomized and multicenter study conducted from January 2005 to December 2015 on the CLIMHET study group cohort from five tertiary centers in France. Data were collected for all patients with LRHC to compare patient characteristics, intraoperative data and postoperative outcomes in terms of medical and surgical complications, duration of hospitalization and mortality. A multivariate analysis was performed to compare the results in the two groups. RESULTS Of the 597 patients undergoing LRHC, 150 had IC and 447 had EC. The incidence of medical complications (cardiac, vascular, and pulmonary complications) was lower in the IC group than in the EC group (13 vs 20%, p = 0.049). This difference remained significant in multivariate analysis after adjusting to field characteristics and patient histories (p = 0.009). Additionally, a shorter hospital stay (7 vs 8 days, p = 0.003) was observed in the IC group as compared to the EC group. This difference remained significant in favor of the IC group in multivariate analysis (p = 0.029). There was no difference between the groups as regards: surgical complications (p = 0.76), time of mobilization (p = 0.93), reintervention rate (p = 1) and 90-day mortality (p = 0.47). CONCLUSIONS Our results show that IC anastomosis in LRHC is associated with fewer medical complications and shorter hospital stays compared to EC anastomosis.

Abstract
Objective: To evaluate safety and efficacy of a novel method of bilateral patent processus vaginalis ligation in transumbilical single-site multiport laparoscopic orchiopexy for children. Methods: A retrospective study was carried out comparing the novel ligation and conventional ligation performed by a single surgeon between July, 2017-July, 2018. The patients were divided into the novel group (42 cases) and the conventional group (59 cases). In the novel group, transumbilical single-site multiport laparoscopic orchiopexy was performed and the bilateral internal rings was stitched with "8" pattern suture. In the conventional group, the conventional TriPort laparoscopic orchiopexy was performed and purse string suture was used to fix the internal rings. The parameters of operative duration time, postoperative hospital stay; postoperative complications were compared between 2 groups. Results: All operations were successful. No Perioperative period complications were found and all patients were discharged within 4-6 days after operation. There is no statistic difference in the surgery time and hospitalization day. However, there is significant difference in the Pain face scale scores after day 2(1.60±0.73 VS 2.02±0.86). And there is no scar and the satisfactory cosmetic could be seen in scrotum and inguinal area in the novel group. Conclusion: The novel ligation was safety and efficacy. It is relatively easy to perform with smaller scar and less pain. We propose the novel ligation as a more viable treatment option for pediatric cryptorchidism with bilateral patent processus vaginalis.

Abstract
Background Single-incision laparoscopic right hemicolectomy (SILS) has long used in surgery for a long time. However, there is barely a systemic review related to the comparison between the SILS and the conventional laparoscopic right hemicolectomy (CLS) for the right colon cancer in the long term follow-up. Herein, we used the most recent articles to compare these two techniques by meta-analysis. Methods We searched PubMed, Web of Science, Cochrane Library and Wanfang databases to compare SILS with CLS for right colon cancer up to May 2019. The operative, postoperative, pathological and mid-term follow-up outcomes of nine studies were extracted and compared. Results A total of 1356 patients participated in 9 studies, while 653 patients were assigned to the SILS group and 703 patients were assigned to the CLS group. The patients’ baselines in the SILS group were consistent with those in the CLS group. Compared to the CLS group, the SILS group had a shorter operation duration (SMD − 23.49, 95%CI − 36.71 to − 10.27, P < 0.001, chi-square = 24.11), shorter hospital stay (SMD − 0.76, 95% `CI − 1.07 to − 0.45, P < 0.001, chi-square = 9.85), less blood loss (SMD − 8.46, 95% CI − 14.59 to − 2.34; P < 0.05; chi-square = 2.26), smaller incision length (SMD − 1.60, 95% CI − 2.66 to − 0.55, P < 0.001; chi-square = 280.44), more lymph node harvested (SMD − 0.98, 95% CI − 1.79 to − 0.16, P < 0.05; chi-square = 4.61), and a longer proximal surgical edge (SMD − 0.51, 95% CI − 0.93 to − 0.09, P < 0.05; chi-square = 2.42). No significant difference was found in other indexes. After we removed a single large study, we performed another meta-analysis again. The operation duration in the SILS group was still better than that in the CLS group. Conclusion SILS could be a faster and more reliable approach than CLS for the right colon cancer and could accelerate patient recovery, especially for patients with a low BMI.

Abstract
Purpose This study aimed to analyze the learning curves for colorectal surgery fellows in a colonoscopy training program. Methods Between May 2003 and February 2017, 60 surgical fellows joined our 1-year colonoscopy training program as trainees and performed 43,784 cases of colonoscopy. All trainees recorded their colonoscopy experiences prospectively into the database. After excluding 6 trainees, who had experience with performing more than 50 colonoscopies before participating in our training program or who discontinued our training program with experience performing less than 300 colonoscopies, this study included 54 trainees who had performed 39,539 colonoscopy cases. We analyzed the cecal intubation rate (CIR) and cecal intubation time (CIT) using the cumulative sum (Cusum) technique and moving average method to assess the technical colonoscopy competence. Results Overall, the CIR by the trainees was 80.7%. The median number of cases of colonoscopy performed during the training period for each trainee was 696 (range, 322–1,669). The trainees were able to achieve a 90% CIR with 412 and 493 procedures when analyzed using the moving average and the Cusum, respectively. Using the moving average method, CIRs after 150, 300, and 400 procedures were 67.0%, 84.1%, and 89.2%, respectively. The CIT of trainees continuously decreased until 400 successful cases. Median CITs were 9.4, 8.3, and 7.4 minutes at 150, 300, and 400 successful cases, respectively. Conclusion We found that more than 400 cases of experience were needed for technical competence in colonoscopy. Continuous teaching and monitoring is required until trainees become sufficiently competent.

Abstract
BACKGROUND AND OBJECTIVES Single-incision plus one port surgery (SILS + 1) provides the advantages of being minimally invasive and easier to perform than pure single-incision laparoscopic surgery. The aim of this study was to investigate the learning curve (LC) for SILS + 1 for sigmoid colon and upper rectal cancer. METHOD From November 2012 to May 2014, a series of 85 consecutive patients underwent selective SLIS + 1 for sigmoid colon and upper rectal cancer performed by a single surgeon at Nanfang Hospital. The LC for SILS + 1 was evaluated using cumulative sum control chart (CUSUM) and risk-adjusted CUSUM methods. Data for all the perioperative variables and pathologic results among the phases were compared. RESULTS The LC had three phases: phase 1 (cases 1-13) was the initial learning period; phase 2 (cases 14-44) was the learning plateau period; and phase 3 (cases 45-85) was the competent period. The differences in total operating time among the three phases were significant. The number of harvested lymph nodes increased along with increases in the surgeon's experience. CONCLUSIONS For experienced CLS surgeons, the learning process reached the plateau period after the 13th case, and technical competence was achieved after the 44th case.

Abstract
This work is a topic highlight on the surgical treatment of the right colon pathologies, focusing on the literature state of art and comparing the open surgery to the different laparoscopic and robotic procedures. Different laparoscopic procedures have been described for the treatment of right colon tumors: Totally laparoscopic right colectomy, laparoscopic assisted right colectomy, laparoscopic facilitated right colectomy, hand-assisted right colectomy, single incision laparoscopic surgery colectomy, robotic right colectomy. Two main characteristics of these techniques are the different type of anastomosis: Intracorporeal (for totally laparoscopic right colectomy, single incision laparoscopic surgery colectomy, laparoscopic assisted right colectomy and robotic technique) or extracorporeal (for laparoscopic assisted right colectomy, laparoscopic facilitated right colectomy, hand-assisted right colectomy and open right colectomy) and the different incision (suprapubic, median or transverse on the right side of abdomen). The different laparoscopic techniques meet the same oncological criteria of radicalism as the open surgery for the right colon. The totally laparoscopic right colectomy with intracorporeal anastomosis and even more the single incision laparoscopic surgery colectomy, remain a technical challenge due to the complexity of procedures (especially for the single incision laparoscopic surgery colectomy) and the particular right colon vascular anatomy but they seem to have some theoretical advantages compared to the other laparoscopic and open procedures. Data reported in literature while confirming the advantages of laparoscopic approach, do not allow to solve controversies about which is the best laparoscopic technique (Intracorporeal vs Extracorporeal Anastomosis) to treat the right colon cancer. However, the laparoscopic techniques with intracorporeal anastomosis for the right colon seem to show some theoretical advantages (functional, technical, oncological and cosmetic advantages) even if all studies conclude that further prospective randomized trials are necessary. Robotic technique may be useful to overcome the problems related to inexperience in laparoscopy in some surgical centers.

Abstract
Single-incision laparoscopic surgery is cosmetically beneficial, but technically challenging. In this study, the learning curve (LC) for single-incision laparoscopic right hemicolectomy (SILRC), incorporating complete mesocolic excision to resect right-sided colon cancer, was investigated through multidimensional techniques. Between December 2009 and May 2015, 64 patients each underwent SILRC of right-sided colon cancer at Severance Hospital, performed in all instances by the same surgeon. Moving average and cumulative sum control chart (CUSUM) were used for LC analyses retrospectively. Surgical failure was defined as conversion to conventional laparoscopic surgery, postsurgical morbidity within 30 days, harvested lymph node count <12, or local tumor recurrence. Both moving average and CUSUM graphics of operative time registered nadirs at the 24th patient, with slight ascent thereafter, reaching a plateau at the 40th patient. The CUSUM for surgical success peaked at the 23rd patient. Operative time for 23 patients in phase 1 (1-23) and for 41 patients in phase 2 (24-64) of the LC did not differ significantly. By comparison, significant differences in patients of phase 2 included larger tumor size, higher harvested lymph node counts, longer proximal resection margins, and more advanced disease. As indicated by multidimensional statistical analyses, the LC for SILRC of right-sided colon cancer was 23 patients. In terms of operative time and surgical success, SILRC is feasible for surgeons experienced in LS, but may prove more challenging for novices, given the fundamental technical difficulties of this procedure.

Abstract
BACKGROUND The use of robotic single-site cholecystectomy has increased exponentially. There are few reports describing the safety, efficacy, and operative learning curve of robotic single-site cholecystectomy either in the community setting or with nonelective surgery. MATERIALS AND METHODS We performed a retrospective review of a prospective database of our initial experience with robotic single-site cholecystectomy. Demographics and perioperative outcomes were evaluated for both urgent and elective cholecystectomy. Cumulative sum analysis was performed to determine the surgeon's learning curve. RESULTS One hundred fifty patients underwent robotic single-site cholecystectomy. Seventy-four (49.3%) patients underwent urgent robotic single-site cholecystectomy, and 76 (50.7%) underwent elective robotic single-site cholecystectomy. Mean total operative time for robotic single-site cholecystectomy was 83.3 ± 2.7 minutes. Mean operative time for the urgent cohort was significantly longer than for the elective cohort (95.0 ± 4.4 versus 71.9 ± 2.6 minutes; P < .001). There was one conversion in the urgent cohort and none in the elective cohort. There was one bile duct injury (0.7%) in the urgent cohort. Perioperative complications occurred in 8.7% of patients, and most consisted of superficial surgical-site infections. There were no incisional hernias detected. The surgeon's learning curve, inclusive of urgent and elective cases, was 48 operations. CONCLUSIONS Robotic single-site cholecystectomy can be performed safely and effectively in both elective and urgent cholecystectomy with a reasonable learning curve and acceptable perioperative outcomes.
