Long-term results in oncology are equivalent to conventional laparoscopic surgery. Keywords: Colon cancer, Single port laparoscopic surgery.

Single-port laparoscopic colectomy in elderly patients with colon cancer: A propensity score-matched comparison with younger patients.

This study aims to evaluate the safety and feasibility of single-port laparoscopic colectomy (SPLC) in elderly patients with colon cancer. During the study period, 344 patients underwent SPLC in our hospital. Among them, 87 patients were aged 80 years and older, and 257 patients were younger than 80 years. After 1:1 propensity-score matching, 87 elderly patients were compared with 87 young patients. Short-term clinical outcomes after SPLC were equivalent between the two groups, although the elderly group had a higher ASA score and more postoperative complications. The 5-year overall survival rates were 64.6% in the elderly group and 66.8% in control group. The 5-year cancer-specific survival rates were 78.0% in the elderly group and 70.9% in control group. There were no significant differences between the groups. Our results indicated that SPLC is technically feasible for operative teams that have adequately standardized the procedure, and it is oncologically safe in elderly patients with colon cancer.

Single port laparoscopic colectomy for colonic cancer

Objectives: The evaluation of feasibility, safety, and outcomes of single port laparoscopic colectomy (SPLC) for colonic cancer. Prospective study of 114 patients with colonic cancer (84 right side, 17 left side, and 13 sigmoid colon) who underwent SPLC between October 2010 and October 2016 in Hue Central Hospital. Results: Mean age of patients was 56.1±15.2 (25-87 years), male/female ratio was 70/44. Mean BMI was 23.5±2.2 kg/m2. Procedures included 84 right hemi-colectomies (73.7%), 17 left hemi-colectomies (14.9%), and 13 sigmoidectomies (11.4%). Six cases required additional ports, and 19 were converted to open surgery. Mean tumor size was 3.7±2.7 cm. Stage I: 6.1%; stage IIa: 43.9%; stage IIIa: 36.8%; and stage IIIc: 13.2%. Mean operation time was 160.5±75.5 min. There had been no deaths/intraoperative complications. Mean incisional length (including extraction) was 5.5±2.2 cm. Mean lymph nodes was 16.2±4.5. Mean hospital stay was 7.5±6.1 days. The surgical site infection rate was 3.5%, and 1 patient required reoperation (anastomotic leakage: 0.9%). After 32.2±7.5 (3-65 months) follow-up, there were no late surgical complication, incisional hernia, or incision metastasis. There were five local recurrences, and three patients developed liver metastasis in the open conversion group. The overall survival time after 2 years was 87.5%, and after 5 years, it was 59.4% (Kaplan-Meier). Conclusion: SPLC is feasible and safe procedure for the treatment of colon cancer. The cosmetic value is better (short incision confounded by umbilicus). Other outcomes were equivalent to conventional laparoscopy.

Dual-port vs. single-port laparoscopic colectomy for colon cancer

Dual-port laparoscopic colectomy (DPLC) has emerged as a surgical option that can overcome the technical limitations of single-port laparoscopic colectomy (SPLC). The aim of this study was to compare perioperative outcomes of DPLC and SPLC for colon cancer. This case-control study assessed 119 patients who underwent colon cancer surgery using DPLC (n = 66) and SPLC (n = 53). Propensity score matching resulted in 42 pairs of patients, equivalent in distribution of TNM stage and tumor size. Perioperative outcomes and postoperative complications were similar in the two groups, except for a tendency toward less blood loss in the DPLC group (50 ml vs. 100 ml, p = 0.087). Umbilical incision sites were significantly more common in the DPLC than in the SPLC group with left-sided colon cancer (94.4% vs. 66.7%, p = 0.032). In a subgroup of patients with stage II–IV tumors, there were no significant between-group differences in perioperative outcomes. These findings show that perioperative outcomes following colon cancer surgery with DPLC were not superior to those achieved with SPLC. DPLC may be associated with better cosmetic outcomes through greater use of an umbilical approach for left-sided colectomies.

Impact of obesity on the short-term outcomes of single-port laparoscopic colectomy for colorectal cancer in the Asian population: A retrospective cohort study.

Single-port laparoscopic surgery (SPLS) is being increasingly performed for treating colorectal cancer. Here, we aimed to assess the safety and feasibility of SPLS for colorectal cancer in obese patients through a comparison of their short-term outcomes with those of nonobese patients.A total of 323 patients who underwent SPLS for colorectal cancer at our center between March 2009 and August 2014 were enrolled. The outcomes were analyzed according to the body mass index (BMI) category: nonobese (BMI < 25), obese I (BMI: 25.0–29.9), and obese II (BMI ≥ 30).Of the 323 patients, 233 (72.1%), 80 (24.8%), and 10 (3.1%), were assigned to the nonobese, obese I, and obese II groups, respectively. The clinicopathologic patient characteristics, such as age, gender, tumor location, and previous laparotomy, were similar among the 3 groups. The mean operative time (nonobese vs obese I vs and obese II groups: 269.2 vs 270.4 vs 342.8 minutes, respectively) and estimated surgical blood loss (277.7 vs 260.5 vs 387.0 mL, respectively) were greater in the obese II group than in the nonobese and obese I groups, although the difference was not significant (P = .247 and P = .205, respectively). However, the time to passage of flatus significantly differed among the groups (P = .040); in particular, this value was significantly longer in the obese II group than in the obese I group (P = .031). None of the other parameters, including conversion to open or conventional laparoscopic surgery and intra- and postoperative morbidity, significantly differed among the 3 groups.SPLS for colorectal cancer can be safely performed in obese Asian patients with equivalent short-term outcomes as compared with that in nonobese patients. Hence, SPLS can be safely recommended for colorectal cancer in obese patients if the surgeon is experienced. Nevertheless, the technique used warrants further investigation, and a large-scale prospective study is required.

Comparative analysis of outcomes after multiport and single-port laparoscopic colectomy in emergency situations: Is single-port laparoscopic colectomy safe and feasible?

Although consensus has been reached on the superiority of laparoscopy for a majority of conditions underlying acute abdominal pain, the safety and feasibility of single-port laparoscopic colectomy (SPLC) in emergency situations have not been determined. A prospective electronic database of all emergency patients who underwent either multiport laparoscopic colectomy (MPLC) or SPLC between April 2006 and December 2014 was used to compare the surgical outcomes of these operative methods. During the study period, 31 MPLCs and 76 SPLCs were performed. These two operative methods resulted in similar operating times, transfusion amounts, lengths of stay, postoperative complications, attainment of lymph nodes, and proximal and distal cut margins. However, the SPLC group had a shorter time to first flatus (2.8±1.9 days vs. 3.8±1.5 days, p=0.005), earlier reinitiation of free oral fluids (3.2±2.1 days vs. 4.4±1.8 days, p=0.002), and lesser requirement of narcotic analgesics (2.5±3.9 times vs. 4.7±4.8 times, p=0.017). SPLC could be a safe and effective alternative to MPLC, even in emergency situations when performed by surgeons who have overcome the learning curve associated with single-port laparoscopic techniques. The tendency toward earlier returns to bowel function and decreased incidence of postoperative analgesic use would be potential benefits of SPLC in emergency situations.

Short-term outcomes following reduced-port, single-port, and multi-port laparoscopic surgery for colon cancer: tailored laparoscopic approaches based on tumor size and nodal status.

Surgeons have recently developed more minimally invasive surgical procedures to reduce surgical stress and improve cosmesis. Although single-port laparoscopic colectomy (SPLC) has potential benefits over multi-port laparoscopic colectomy (MPLC), there are concerns about the increased technical difficulties associated with SPLC. Therefore, we attempted reduced-port laparoscopic colectomy (RPLC). The purpose of this study was to evaluate the difference in perioperative outcome following tailored laparoscopic approaches for colon cancer on the basis of tumor characteristics. The prospectively collected data of 170 patients who underwent only minimally invasive colectomy for colon cancer from July 2010 to June 2013 were reviewed. The MPLC, SPLC, and RPLC groups comprised 92 (54.1 %), 40 (23.5 %), and 38 (22.4 %) patients, respectively. The number of harvested lymph nodes was significantly higher in the RPLC group than in the MPLC and SPLC groups (29.9 ± 21.5, 21.9 ± 12.1, and 24.2 ± 13.8, respectively; p = 0.027). The mean operating time was significantly different among the MPLC, SPLC, and RPLC groups (243.5 ± 59.0, 207.2 ± 49.6, and 216.2 ± 53.7 min, respectively; p = 0.001). The time to first flatus was also significantly different among the MPLC, SPLC, and RPLC groups (3.1 ± 1.2, 3.6 ± 1.3, and 3.4 ± 1.1 days, respectively; p = 0.039). No significant differences in the other short-term surgical outcomes were observed among the three groups. SPLC and RPLC according to tailored laparoscopic approaches for colon cancer appear to be beneficial in terms of operative time and lymph node retrieval, and may be considered as surgical options in laparoscopic colectomy for colon cancer patients with favorable tumor characteristics.

SINGLE PORT LAPAROSCOPIC SURGERY FOR RIGHT COLON CANCER CAUSE ANALYSIS FOR CONVERSION TO LAPAROTOMY

Purpose: Analysis about disease, technical characteristics of 17 right colon cancer patients underwent conversion to laparotomy from single port laparoscopic surgery and propose related factors for indications. Methold: Consist of 17 colon cancer patients, who were conversion to laparotomy from single port laparoscopic colectomy at Hue Central Hospital from october 2010 to august 2014. Results: Mean age 61.3±14.2 years, rate male/female 11/6. Tumor invasion: T2 11.8%, T3 58.8%, T4 29.4%. Mean tumor size on CT 6.5±2.2cm. The causes of conversion: very big tumors 29.4%, invasive-adhesive tumors 47.1%, extended surgery 23.5%. Open procedures: right hemicolectomy 70.6%, right hemicolectomy plus cholecystectomy 5.9%, right hemicolectomy plus wedge-shape duodenectomy 11.8%, right hemicolectomy plus intestinal segmentectomy 5.9% and right hemicolectomy plus low-anterior rectal resection, hysterectomy 5.9%. Conclusion: Conversion to laparotomy from single port laparoscopic colectomy is necessary for very big tumors, excessive tumor adhesions and exceed the technical limitations of laparoscopic dissection. Key words: Single incision laparoscopic colectomy (SILC), single port laparoscopic colectomy (SILC), conversion to laparotomy.

Single-port laparoscopic colectomy is safe and feasible in patients with previous abdominal surgery

BackgroundThe aim of this study was to assess the impact of previous abdominal surgery (PAS) on single-port laparoscopic colectomy (SPLC). MethodsWe studied 429 consecutive patients who underwent SPLC in our department from May 2009 to December 2013. Patients were divided into 2 groups: those with PAS (PAS group) and those with NPAS (NPAS group). Operative parameters and outcomes were analyzed between the 2 groups retrospectively. ResultsSPLC was performed in 152 PAS patients and 277 NPAS patients. Eight patients in the PAS group and 6 patients in the NPAS group were converted to multiport laparoscopic colectomy (5.3% vs 2.2%, respectively; P = .077). Three patients in the PAS group and 2 patients in the NPAS group had inadvertent enterotomy (2.0% vs .7%, respectively; P = .352). No patients were converted to open surgery. There were no significant differences between the 2 groups in terms of blood loss, operative time, and postoperative outcomes. ConclusionOur experience has demonstrated the safety and feasibility of SPLC in patients with PAS.

Single-port laparoscopic right hemicolectomy: the learning curve.

Single-port laparoscopic colectomy is described as a new technique in colorectal surgery. The initial case reports show the safety and feasibility, but the learning curve for this technique is unknown. Between July 2009 and September 2010, 20 consecutive patients with an indication for right hemicolectomy underwent a single-port laparoscopic approach without bias in selection. The only exclusion criterion was a prior midline laparotomy. The patients were followed up for 30 days. Chart review was completed for up to 35 months to assess long-term morbidity and mortality rates. The median age was 65 years (range, 59-88 years). Ninety percent of patients were men. The median body mass index was 28 kg/m(2) (range, 20-35 kg/m(2)). Seventy-five percent of patients had significant comorbidities with an American Society of Anesthesiologists class of 3 or 4. The estimated blood loss was 25 mL (range, 25-250 mL). The median number of pathologic lymph nodes for patients diagnosed with adenocarcinoma was 16 (range, 8-23). There was one conversion to hand-assisted laparoscopic (case 6) and one to open colectomy (case 9) because of the inability to achieve safe vessel ligation. The median hospital stay was 4.5 days (range, 3-7 days). The length of stay for the first 10 patients was 5.1 days, and it was 3.9 days for the last 10 patients (P = .045). There were no significant postoperative complications within 30 days. The mean operative time for the first 10 cases was 198 minutes (range, 148-272 minutes), and it was 123 minutes (range, 98-150 minutes) for the subsequent 10 cases (P = .0001). All intraoperative complications (minor bleeding) occurred within the first 10 patients, with no significant bleeding recorded for the last 10 cases. Single-port laparoscopic right hemicolectomy can be safely performed in patients who are candidates for conventional or hand-assisted right hemicolectomy with very low intraoperative and postoperative complication rates. The 30-day morbidity rate remained low with this technique. The higher technical difficulty compared with conventional laparoscopy is reflected in the longer initial operative times. The learning curve for a surgeon with advanced laparoscopic skills and adequate procedure numbers seems to be short, requiring approximately 10 cases to decrease operative times to baseline. The role and feasibility of broad adaptation for single-incision laparoscopy in colorectal surgery need to be further evaluated in larger case series and trials.

Single-Port Laparoscopic Right Hemicolectomy: Intermediate Results

Single-port laparoscopic colectomy was first described in 2008 as a new technique for colorectal surgery. No available reports have stated the intermediate- or long-term outcome. We report our intermediate results for the first 20 single-port laparoscopic right hemicolectomies performed by a single laparoscopically trained surgeon at our institution. Between February 2009 and September 2010, 20 consecutive patients with an indication for right hemicolectomy who were candidates for laparoscopic surgery underwent a single-port laparoscopic approach. The only exclusion was a previous midline laparotomy. The patients were followed for outcomes after a median of 27 months (range: 15 to 35). The mean age was 65 years (range: 59 to 88). The mean body mass index was 28 (range: 20 to 35). Seventy five percent of patients had significant comorbidities, with an American Society of Anesthesiologists class of III or IV. The median estimated blood loss was 25 mL (range: 25 to 250). The mean number of lymph nodes was 13 (range: 0 to 29). There was one conversion to hand-assisted laparoscopic colectomy and one to open colectomy secondary to bleeding. The mean hospital stay was 5 days (range: 3 to 7). Thirty-day postoperative complications included 1 wound infection, 1 patient with alcohol withdrawal, and 1 incidence of colitis caused by Clostridium difficile infection. At a median follow-up of 27 months, there were no local recurrences or distant metastases. One death occurred at 17 months from myocardial infarction. Two patients developed incisional hernias, with one requiring a laparoscopic hernia repair. One patient required a completion proctocolectomy for a pathological diagnosis of hyperplastic polyposis syndrome. Single-port laparoscopic right hemicolectomy has been safely performed in patients who are candidates for conventional laparoscopic hemicolectomy. This small series indicates that intermediate-term results are similar to conventional laparoscopic surgery in efficacy, safety, and oncological outcomes. Larger datasets are necessary to determine cost-effectiveness, differences in postoperative outcomes, and patient satisfaction.

Single-incision versus conventional laparoscopic colectomy for colonic neoplasm: a randomized, controlled trial

Single-incision laparoscopic colectomy (SILC) is a newly developed procedure with the benefit of better cosmetic outcome and potentially reduced wound pain compared with conventionally laparoscopic colectomy (CLC). However, the application of SILC requires careful evaluation to prove its benefit and safety. This randomized, controlled study compared the operative outcome of patients who underwent SILC and CLC. Patients who had small cancer (<4 cm) or adenomatous polyp requiring colectomy were randomized to have SILC or CLC. The patients were blinded to the procedures and the postoperative pain was used as the primary outcome measure. All patients had patient-controlled analgesia with intravenous morphine after the operation and the nominal rating score on days 1-3 and day 14 were recorded by research staff, who did not known the types of operations. Other operative outcomes of the two groups of patients also were recorded prospectively and compared. There were 25 patients in each group. The patients' demographics, tumor characteristics, operating time, blood loss, complication rate, number of lymph nodes harvested, and resection margin have no statistically significant difference between the two groups. There was no operative mortality in both groups. The SILC group had consistently lower median pain score than CLC group in the whole postoperative course and the difference was statistically significant on day 1 (0 (0-5) vs. day 3 (0-6) respectively; p = 0.002) and day 2 (0 (0-3) vs. 2 (0-8) respectively; p = 0.014). The median hospital stay in the SILC group also was shorter the CLC group. In a selected group of patients with small tumor and good operative risk, SILC is a safe alternative to CLC. Single-port laparoscopic colectomy also is associated with the benefits of less postoperative pain and shorter hospital stay than CLC.

Single-port laparoscopic colectomy versus conventional laparoscopic colectomy for colon cancer: a comparison of surgical results

BackgroundSingle-port laparoscopic surgery is a new technique that leaves no visible scar. This new technique has generated strong interest among surgeons worldwide. However, single-port laparoscopic colon surgery has not yet been standardized. Our aim in this study was to evaluate the feasibility of single-port laparoscopic colectomy compared with conventional laparoscopic colectomy for colon cancer.MethodsWe conducted a case-matched, controlled study comparing single-port laparoscopic colectomy to conventional laparoscopic colectomy for right-sided colon cancer.ResultsA total of ten patients were included for the single-port laparoscopic colectomy (S-LAC) group and ten patients for the conventional laparoscopic colectomy (C-LAC) group. The length of the skin incision in the S-LAC group was significantly shorter than that of the C-LAC group.ConclusionOur early experiences indicated that S-LAC for right-sided colon cancer is a feasible and safe procedure and that S-LAC results in a better cosmetic outcome.

Outcomes for case‐matched single‐port colectomy are comparable with conventional laparoscopic colectomy

With the introduction of single-port surgery, expected advantages are improved cosmesis, decrease of pain and shorter length of stay. The aim of this study was to compare early outcomes of single-port colectomy with those of conventional laparoscopic colectomy. All consecutive patients undergoing single-port colectomy between January and June 2010 were identified from a prospective database. They were matched for age, sex, body mass index, American Society of Anesthesiology score and type of resection with patients who had conventional laparoscopic colectomy. All perioperative data, analgesic requirement, pain scores and inflammatory response were compared using the Wilcoxon signed-rank and McNemar tests. Fourteen patients [five men, nine women; median age (interquartile range) 56 (30-73) years, body mass index (interquartile range) 22 (20-24) kg/m2] underwent single-port colectomy and were matched with patients who had conventional laparoscopic colectomy. Median operating times, estimated blood loss, pain scores, analgesic requirement, inflammatory response and length of hospital stay were similar. Median increase in incision length was significantly higher in the single-port group (P=0.004), but maximal incision length for specimen extraction was comparable. There were no anastomotic leaks, wound infections or 30-day readmissions. In a case-matched setting with a small sample size, single-port laparoscopic colectomy has comparable outcomes to conventional laparoscopic colectomy.

Single-Port Laparoscopic Total Colectomy for Medically Uncontrolled Colitis

New-generation multi-instrument ports for laparoscopic surgery now allow abdominal surgery via a single-access small incision. Here, we detail how laparoscopic total colectomy can be safely performed within the constraints of such single site operating. Three patients (2 males and 1 female; mean age, 28.3 y; mean body mass index, 24.1 kg/m) requiring urgent total colectomy with end ileostomy for colitis resistant to medical therapy fully consented to have their operation performed by a single-port laparoscopic approach. The single port was placed at the site marked preoperatively for the end ileostomy. The operation commenced with rectosigmoid transection and proceeded with a close pericolic dissection proximally along the colon to the cecum. The resected colon was withdrawn via the port site and the end ileostomy fashioned within this wound. The operation was safely completed in its entirety without additional abdominal access in each case. Mean operative time was 206 minutes. All patients are well with normal stoma appearance and function at a minimum follow-up of 4 months. Judicious patient selection and considered operative technique allow major resectional colonic surgery to be safely performed solely by a single-port technique. Proof of clinical benefit along with refined instrumentation is required if such surgery is to progress from anecdotal reports to mainstream practice.

Laparoscopic single-port colectomy for sigmoid cancer

Single-port laparoscopic surgery can be performed via one incision hidden in the umbilicus. Herein, we report a patient with a sigmoid colon cancer undergoing single-port laparoscopic sigmoid colectomy. Laparoscopic single-port sigmoid colectomy through a 3-cm umbilical incision was performed on a patient with a diagnosis of sigmoid cancer. Patient was 54-year-old female with a body mass index of 25.8 kg/m(2). Preoperatively, a CAT scan in the metastasis evaluation did not show any lesion. The total operative time was 198 min. Estimated blood loss was 300 ml. Length of hospital stay was 3 days. Patient had no intraoperative or postoperative complications. Examination of pathological specimen showed a specimen containing a circumferential lesion measuring 5 cm x 2.5 cm x 2.5 cm with adequate surgical margins (10 and 5.5 cm), and no regional lymph node metastases in 14 lymph nodes collected. Patient did not receive adjuvant chemotherapy after surgery. Colonoscopy performed 1 year after surgery showed no neoplasm or polyp identified. Abdomen and pelvis CT also found no evidence of recurrence or metastatic disease. Single-port laparoscopic surgery may allow common benign procedures via an incision in the umbilicus. It can also be performed with good surgical and oncologic results in selected patients with a colorectal cancer.
