Evolution of laparoscopy in colorectal surgery: An evidence-based review

Open Versus Minimally Invasive Emergent Colectomy for Diverticulitis

BACKGROUND

The role of minimally invasive surgery (MIS) in the acute management of diverticulitis remains controversial. Using a national cohort, we examined the relationship between operative approaches with acute clinical and financial outcomes.

METHODS

Adults undergoing emergent colectomy for diverticulitis were tabulated from the 2015-2020 American College of Surgeons National Surgical Quality Improvement Program. Regression models were developed to analyze the association between open and MIS approaches with major adverse events (MAE), as well as secondary endpoints. A subgroup analysis was conducted to compare outcomes between open and MIS requiring conversion to open (CTO).

RESULTS

Of 9194 patients, 1580 (17.3%) underwent MIS colectomy. The proportion of MIS resection increased from 15.1% in 2015 to 19.1% in 2020 (nptrend<.001). Compared to Open, MIS patients were younger, equally likely to be female, had a lower proportion of patients with ASA class ≥3, and a higher BMI. Preoperatively, MIS patients were less frequently diagnosed with sepsis. Following adjustment with open as reference, MIS approach had reduced odds of MAE (AOR .56), ostomy creation (AOR .12), shorter postoperative length of stay (LOS; β -1.63), and a lower likelihood of nonhome discharge (AOR .45, all P < .001). Additionally, CTO was linked to decreased likelihood of MAE (AOR .78, P = .01), ostomy creation (AOR .02, P < .001), comparable LOS (β -.46, P = .41), and reduced odds of nonhome discharge (AOR .58, P < .001), relative to open.

DISCUSSION

Compared to planned open colectomy, MIS resection was associated with improved clinical and financial outcomes, even in cases of CTO. Our findings suggest that whenever possible, MIS should be attempted first in emergent colectomy for diverticulitis. Nevertheless, future prospective studies are likely needed to further elucidate specific patient and clinical factors.

Colorectal cancer: Recent advances in management and treatment

Colorectal cancer (CRC) is the third most common cancer worldwide, and the second most common cause of cancer-related death. In 2020, the estimated number of deaths due to CRC was approximately 930000, accounting for 10% of all cancer deaths worldwide. Accordingly, there is a vast amount of ongoing research aiming to find new and improved treatment modalities for CRC that can potentially increase survival and decrease overall morbidity and mortality. Current management strategies for CRC include surgical procedures for resectable cases, and radiotherapy, chemotherapy, and immunotherapy, in addition to their combination, for non-resectable tumors. Despite these options, CRC remains incurable in 50% of cases. Nonetheless, significant improvements in research techniques have allowed for treatment approaches for CRC to be frequently updated, leading to the availability of new drugs and therapeutic strategies. This review summarizes the most recent therapeutic approaches for CRC, with special emphasis on new strategies that are currently being studied and have great potential to improve the prognosis and lifespan of patients with CRC.

[Robotic Colorectal Surgery: Analysis of the First Three Years of Activity in a Hospital of the Portuguese National Health Service]

INTRODUCTION

Minimally invasive surgery has been increasingly accepted and used in colorectal surgery. Several studies report that robotic surgery may provide advantages over 'conventional' laparoscopy, namely in rectal surgery. This paper provides an account of the first three years of experience with robotic surgery in the Unidade de Patologia Colorretal of the Unidade Local de Saúde S. José.

METHODS

Variables were defined to develop a prospective database containing the data of consecutive patients operated by three internationally certified colorectal surgeons using the Da Vinci Xi® system between November 2019 and October 2022. The database was converted into an anonymized version that was used for this study. The analysis was performed on the data of all the patients operated during this period.

RESULTS

Eighty patients were included, 47 male, median age 70 years, and median BMI 26 kg/m2 . ASA score was II in 53.7% and III in 41.3% of pa- tients. Of the total, 97.6% had malignant or potentially malignant disease. Operative procedures consisted of 34 colectomies proximal to the splenic flexure, 20 distal colectomies and 26 anterior resections. There were two synchronous resections of liver metastases. Early perioperative outcomes and histopathological results were analyzed: median operative time: 300 minutes; median estimated blood loss: 50 mL; conversion rate: 2.5%; median days until first bowel movement: three days; median length of hospital stay: six days; complication rate: 20%, of which 5% were Clavien III and 0% Clavien IV/V; anastomotic leak rate: 2.5%; 30-day readmission rate: 1.3%; median lymph nodes resected: 20; R0 resection rate: 100%; mesorectal integrity rate: 95,8% complete/near complete.

CONCLUSION

Our results show that the adoption of robotic colorectal surgery in our center was safe and resulted in similar or improved short-term clinical outcomes and histopathological results when compared to those described in the literature.

Comparative Analysis of Laparoscopic Versus Open Procedures in Specific General Surgical Interventions

Laparoscopic and open surgeries are two distinct surgical approaches with significantly different procedures and outcomes. Minimally invasive surgery, also known as laparoscopic surgery, utilizes small incisions and specialized instruments like the laparoscope to perform procedures. This contrasts with open surgery, which requires larger incisions to directly access the surgical site. Open surgery was the preferred approach for any invasive procedure until the introduction of new technological advances in the form of laparoscopy. While laparoscopy is still evolving, preliminary results demonstrate promise for various operations. Open surgery provides the healthcare professional with more liberty in the form of increased visualization, but it also increases tissue damage and hospital stays. Laparoscopic and open procedures are both valuable surgical methods with advantages and disadvantages. While open surgery is favored for difficult patients, laparoscopic surgery offers a quicker recovery and fewer scars. The choice between the two approaches depends on the patient's condition, surgical demands, and the surgeon's skills. As these methods develop, they become increasingly important for offering safe and efficient surgical treatments across a range of medical specialties.

Is non-mentored initiation of laparoscopic colorectal surgery safe? Single surgeon initial experience with the first 40 cases

Introduction

Although laparoscopic colorectal surgery is now accepted as a standard procedure in treating colorectal cancer, the proportion of laparoscopically operated patients with colorectal cancer is still generally quite low. The aim of this study is to assess feasibility, safety, and outcomes of a non-mentored initiation of laparoscopic colorectal resections by a young surgeon without previous experience in laparoscopic colorectal surgery.

Materials and methods

We analyzed the characteristics of the first 40 elective cases of laparoscopic colorectal resections performed by a single surgeon during the period between June 2019 and March 2022. All of the operations were performed without the attendance or supervision of an experienced surgeon in laparoscopic colorectal surgery. The patients were divided into three groups (the early, intermediate, and late group).

Results

The conversion rate, complications rate, and postoperative recovery were similar among groups. The mean overall operative time was 219.5 min (range 130-420 min) and had reduced significantly during the learning curve (p = 0.047). The overall conversion rate was 12.5%. In two cases (5%), the oncological principles were violated (incomplete total mesorectal excision). In three patients (7.5%), intraoperative complications had occurred (small bowel injury, splenic injury, and significant bleeding from the minor peripancreatic artery). Three cases of major postoperative complications (Clavien-Dindo grade III) were recorded, two of which required reoperation (anastomotic bleeding and fascial dehiscence). There was no 90-day mortality reported. The overall mean number of lymph nodes retrieved was 12.45, which did not differ significantly among groups (p = 0.678). The average follow-up was 13.75 months (range 1-31 months). Cancer recurrence was recorded in four patients (10%). Port-site metastasis was not detected in any of the cases.

Conclusion

A safe and non-mentored initiation of laparoscopic colorectal surgery with an acceptable rate of complications and acceptable oncological results can be achieved. Still, when compared with a structured initiation in a controlled environment with the supervision of an experienced surgeon in laparoscopic colorectal surgery, the results of a non-mentored initiation are worse in most of the fields, including operative time, conversion rate, complications rate, and duration of hospital stay. Therefore, I strongly recommend engaging young surgeons in fellowship programs on structured laparoscopic colorectal surgery whenever possible before starting performing these procedures on their own.

Comparison of postoperative analgesic effects of thoracic epidural analgesia and rectus sheath block in laparoscopic abdominal surgery: A randomized controlled noninferiority trial

INTRODUCTION

In the Enhanced Recovery After Surgery program, abdominal wall blocks are strongly recommended as postoperative multimodal analgesia for laparoscopic abdominal surgery. The purpose of this study was to compare the efficacy of single-shot rectus sheath block (RSB) with that of thoracic epidural analgesia (TEA) as a method of multimodal analgesia in patients receiving conventional laparoscopic abdominal surgery.

METHODS

A noninferiority comparison was performed. Patients scheduled for laparoscopic gastric or colorectal surgery were enrolled in this study. Patients were divided randomly into two groups: TEA and RSB. The primary endpoint was the numerical rating scale (NRS) score upon coughing as of 24 hours after surgery.

RESULTS

In total, 80 patients were randomly assigned to receive TEA (n = 42) or RSB (n = 38). Three patients were excluded from the TEA group after randomization. The NRS score on coughing as of 24 hours after surgery was significantly lower in the TEA group than in the RSB group (least square mean: 3.59 vs 6.39; 95% confidence interval for the difference: 1.87 to 3.74, P < .001). The NRS scores upon coughing and at rest were significantly lower in the TEA group than in the RSB group as of 4, 24 and 48 hours after surgery. Patient satisfaction with postoperative analgesia was significantly higher in the TEA group. Postoperative adverse events were not significantly different between groups.

CONCLUSION

This is the first report of comparing RSB with TEA in laparoscopic surgery. TEA may be recommended as a multimodal analgesia protocol for laparoscopic gastric and colorectal surgery.

Laparoscopic Intracorporeal Anastomosis

Given the progression of laparoscopic surgery, questions continue to arise as to the ideal technique for a laparoscopic colectomy. The most debated of these questions is whether it is best to complete an intracorporeal (ICA) or extracorporeal (ECA) intestinal anastomosis. Here, we review the literature to date and report the equivalent safety and efficacy of ICA and ECA for laparoscopic right colectomy. However, these studies also indicate that when completed, ICA may prove beneficial with respect to earlier return of bowel function, less postoperative pain, shorter incision length, and reduced risk of wound infections. For this, we present the tips and tricks for completing all forms of laparoscopic ICAs during laparoscopic colectomy.

Internal Hernia After Laparoscopic Left Colectomy: Case Series and Review of the Literature

Objective Laparoscopic colectomy has gained acceptance as a standard treatment for benign and malignant colorectal disease, such as diverticular disease and cancer, among others. Same as in open surgery, the laparoscopic approach carries a low risk of small bowel obstruction in the postoperative period, but in laparoscopic surgery, internal hernia after laparoscopic left colectomy may be a cause of small bowel obstruction with a significant risk of morbidity and mortality. This rare complication may be prevented with routine closure of the mesenteric defects created during the colectomy.

Methods We present four cases of internal herniation after laparoscopic colectomy. Two cases were after laparoscopic left colectomy and two after laparoscopic low anterior resection. All four cases had full splenic flexure mobilization. Routine closure of the mesenteric defect was not performed in the initial surgery.

Results The four patients were treated by laparoscopic reintervention with closure of the mesenteric defect. In two of them, conversion to open surgery was necessary. One of the patients developed recurrent internal herniation after surgical reintervention with mesenteric closure of the defect. All patients were managed without need for bowel resection, and mortality rate was 0%.

Conclusion Internal herniation after laparoscopic colorectal surgery is a highly morbid complication that requires prompt diagnosis and management and should be suspected in the early postoperative period. Additional studies with extended follow-up are required to establish recommendations regarding its prevention and management.

Laparoscopic surgery for colorectal cancer in an elderly population with high comorbidity: a single centre experience

PURPOSE

The use of laparoscopic surgery for colorectal cancer in elderly patients with high comorbidity is a controversial subject. This retrospective analysis aims to compare two different age groups with respect to short and long term clinical and oncological outcomes.

METHODS

All laparoscopic colorectal resections for cancer performed between February 2011 and October 2017 with curative or palliative intention were evaluated.

RESULTS

Among 128 completed resections, the rate of major complications, length of hospital stays, 30-day mortality, 2-year recurrence rate, and the survival after palliative surgery were comparable between group A (< 75 years; n = 76) and B (≥ 75 years; n = 52). Patients in group B showed an extraordinarily high proportion of ASA III stage (73.1% vs. A: 35.5%; p < 0.01) and, in this context, an increased rate of minor postoperative complications (17.3% vs. A: 6.6%; p < 0.05) and lower overall 2 and 5-year survival rates. Within the first 2 years, they died sooner in the event of recurrence (57.1% vs. A: 18.2%; p < 0.05), and their survival after rectal resection, especially for low rectal carcinoma, was significantly reduced (58.8% vs. A: 96.7%; p < 0.001).

CONCLUSION

Laparoscopic surgery for colorectal cancer can be strongly advocated for elderly patients even in the face of high comorbidity. Whether very old patients with low rectal carcinoma also benefit from minimally invasive surgery or should undergo alternative therapies would need to be clarified primarily by examining the quality of life.

Robotic-assisted colorectal surgery - initial results

INTRODUCTION

The mini invasive procedure in colorectal surgery is gaining ground as an alternative to conventional surgery. Colorectal surgery has significantly evolved since the advent of the automatic stapler devices and subsequently with the minimally invasive approach. The next logical step - the robotic assisted surgery was developed to satisfy surgeons' needs to the area of colorectal surgery and to offer a new and safer method to patients. The evidence for benefits of its use in this area appears to be promising.

Antibiotic Bowel Decontamination in Gastrointestinal Surgery—A Single-Center 20 Years’ Experience

Objective

Anastomotic leakage, surgical site infections, and other infectious complications are still common complications in gastrointestinal surgery. The concept of perioperative antibiotic bowel decontamination demonstrates beneficial effects in single randomized controlled trials (RCTs), but data from routine clinical use are still sparse. Our aim was to analyze the data from the routine clinical use of perioperative antibiotic bowel decontamination in gastrointestinal surgery.

Methods

Based on 20 years’ experience, we performed a retrospective analysis of all cases in oncologic gastrointestinal surgery with the use of antibiotic bowel decontamination in gastric, sigmoid, and rectal cancer. Clinical data and perioperative outcomes were analyzed, especially regarding anastomotic leakage, surgical site infections, and other infectious complications.

Results

A total of n = 477 cases of gastrointestinal surgery in gastric cancer (n = 80), sigmoid cancer (n = 168), and rectal cancer (n = 229) using a perioperative regimen of antibiotic bowel decontamination could be included in this analysis. Overall, anastomotic leakage occurred in 4.4% (2.5% gastric cancer, 3.0% sigmoid cancer, 6.1% rectal cancer) and surgical site infections in 9.6% (6.3% gastric cancer, 9.5% sigmoid cancer, 10.9% rectal cancer). The incidence of all infectious complications was 13.6% (12.5% gastric cancer, 11.3% sigmoid cancer, 15.7% rectal cancer). Mortality was low, with an overall rate of 1.1% (1.3% gastric cancer, 1.8% sigmoid cancer, 0.4% rectal cancer). Antibiotic decontamination was completed in 98.5%. No adverse effects of antibiotic bowel decontamination could be observed.

Conclusion

Overall, in this large cohort, we can report low rates of surgery-related serious morbidity and mortality when perioperative antibiotic bowel decontamination is performed. The rates are lower than other clinical reports. In our clinical experience, the use of perioperative antibiotic bowel decontamination appears to improve patient safety and surgical outcomes during gastrointestinal oncologic procedures in a routine clinical setting.

Early results of the implementation of laparoscopic major liver resection program

Background

Laparoscopic liver resections offer potential benefits but may require advanced laparoscopic skills and are volume dependent.

Methods

This retrospective study included 12 patients who underwent major laparoscopic resection and 24 patients after open major liver resection for liver malignancy in the time period between September 2020 and May 2021. The primary outcomes were complications according to Clavien-Dindo classification and duration of hospital stay.

Results

Median duration of hospital stay in laparoscopic resection group (6 days) was significantly shorter than in open resection group (8 days) (p = 0.046). Complications classified as grade II or higher were significantly less frequent in the laparoscopic resection group (2 patients) versus open resection group (13 patients) (p = 0.031).

Conclusions

Although laparoscopic major liver resections should be limited to expert hepatobiliary centers and are characterized by long learning curve, this approach may offer favorable short-term outcomes even during launching a new program.

2D vs 3D laparoscopic right colectomy: A propensity score-matching comparison of personal experience with systematic review and meta-analysis

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.

Comparison between epidural and intravenous analgesia effects on disease-free survival after colorectal cancer surgery: a randomised multicentre controlled trial

Background

Thoracic epidural analgesia (TEA) has been suggested to improve survival after curative surgery for colorectal cancer compared with systemic opioid analgesia. The evidence, exclusively based on retrospective studies, is contradictory.

Methods

In this prospective, multicentre study, patients scheduled for elective colorectal cancer surgery between June 2011 and May 2017 were randomised to TEA or patient-controlled i.v. analgesia (PCA) with morphine. The primary endpoint was disease-free survival at 5 yr after surgery. Secondary outcomes were postoperative pain, complications, length of stay (LOS) at the hospital, and first return to intended oncologic therapy (RIOT).

Results

We enrolled 221 (110 TEA and 111 PCA) patients in the study, and 180 (89 TEA and 91 PCA) were included in the primary outcome. Disease-free survival at 5 yr was 76% in the TEA group and 69% in the PCA group; unadjusted hazard ratio (HR): 1.31 (95% confidence interval [CI]: 0.74–2.32), P=0.35; adjusted HR: 1.19 (95% CI: 0.61–2.31), P=0.61. Patients in the TEA group had significantly better pain relief during the first 24 h, but not thereafter, in open and minimally invasive procedures. There were no differences in postoperative complications, LOS, or RIOT between the groups.

Conclusions

There was no significant difference between the TEA and PCA groups in disease-free survival at 5 yr in patients undergoing surgery for colorectal cancer. Other than a reduction in postoperative pain during the first 24 h after surgery, no other differences were found between TEA compared with i.v. PCA with morphine.

The most highly cited articles of the Revista de Gastroenterología de México over a 22-year period (1996-2018)

INTRODUCTION AND AIM

The Revista de Gastroenterología de México (RGM), founded in 1935, is one of the most influential journals of scientific dissemination in Mexico and Latin America. The aim of the present review was to characterize the RGM's most frequently cited original articles, review articles, and consensuses.

METHODS

The most cited original articles, review articles, and consensuses of the RGM were identified using the Scopus, PubMed, and Google Scholar databases. Their designs and topics, as well as their authors and participating institutions, were analyzed.

RESULTS

The most highly cited articles of the RGM corresponded to the period from 1996 to 2018, with a mean of 16.5 citations per article. Fifty-eight percent (n = 29) of the articles belonged to the area of gastroenterology and 20% (n = 10) to surgery. The most frequent topics were functional gastrointestinal disorders, hepatitis virus, and gastric cancer. Thirty-six percent of the articles had a nonrandomized prospective design, followed by cross-sectional studies (26%) and randomized prospective studies (18%).

CONCLUSION

The 50 most-cited articles included a total of 826 citations and the 10 most-cited consensuses and review articles had a total of 208 citations. Those studies encompass a diversity of disciplines related to gastroenterology that have impacted the scientific community and correspond to the work of different active research groups in Mexico and other countries.

Comparison of the continuation and discontinuation of perioperative antiplatelet therapy in laparoscopic surgery for colorectal cancer: A retrospective, multicenter, observational study (YCOG 1603)

AIM

The present study aimed to examine the effect of continuing antiplatelet therapy in the perioperative period for patients undergoing laparoscopic resection for colorectal cancer who had received preoperative antiplatelet therapy.

METHODS

This retrospective, multicenter, observational study included patients who underwent laparoscopic surgery for colorectal cancer between January 2011 and May 2020. The study population was limited to patients who used antiplatelet therapy preoperatively.

RESULTS

A total of 214 colorectal cancer patients who received antiplatelet therapy preoperatively were included in the present study. Eighty-nine patients underwent surgery under the continuation of antiplatelet therapy, and 125 patients underwent surgery under the discontinuation of antiplatelet therapy before surgery. There were no significant differences between the two groups with regard to intraoperative blood loss (P = .889), intraoperative blood transfusion (P = 1.000), and conversion to laparotomy (P = 1.000). There were no significant differences between the two groups in the incidence of postoperative hemorrhagic complications (Clavien-Dindo Grade ≥II, P = .453; Grade ≥III, P = .572) or three-point major adverse cardiovascular events (P = .268). However, there were two cases of postoperative non-fatal stroke in the discontinued antiplatelet therapy group.

CONCLUSIONS

The present study revealed that there were no significant differences in the surgical outcomes and postoperative complications between colorectal cancer patients who underwent laparoscopic resection with the continuation of antiplatelet therapy in the perioperative period and those in whom antiplatelet therapy was discontinued during the perioperative period. From the viewpoint of cardiovascular and cerebrovascular risk, it may be better for patients undergoing laparoscopic surgery for colorectal cancer to continue antiplatelet therapy. This study was registered with the Japanese Clinical Trials Registry as UMIN000038707 (http://www.umin.ac.jp/ctr/index.htm).

Robotic versus Laparoscopic Sigmoid Colectomy: Analysis of Healthcare Cost and Utilization Project Database

Minimally invasive sigmoid colectomy via the laparoscopic approach (LA) has numerous benefits. We seek to compare outcomes between laparoscopic and robotic sigmoid colectomies. We analyzed the data using the National Inpatient Sample database between 2008 and 2014. Utilization and outcome measures were compared. The seven-year average number of patients who underwent elective sigmoid colectomy in the United States from 2008 to 2014 was estimated to be 197,053. Of these, 95.1 per cent were conducted using the LA. The mean age was 58.33 + 13.6 years and 58.23 + 12.8 years in laparoscopic and robotic approaches, respectively. No significant differences existed in respect to morbidities. Postoperative complications were comparable with respect to other complications. Length of hospital stay was statistically significantly shorter in the robot-assisted approach compared with the LA (mean 4.8 + 4 vs 5.7 + 5 days, respectively, P < 0.001). Patients who underwent robotic surgery had significantly higher total hospital charges than those who underwent laparoscopic surgery (median $45,057 vs $57,871 USD, P < 0.001). The advent of robot-assisted surgery has provided more options for patients and surgeons. Compared with laparoscopy, robot-assisted sigmoid colectomy has no clinical advantages in morbidity and mortality. However, the robotic approach has a significantly higher total charge to the patient.

Lessons Learned from the Introduction of Laparoscopic Pancreaticoduodenectomy

Introduction: Minimally invasive techniques have been suggested to achieve enhanced recovery and improved outcome after pancreaticoduodenectomy (PD). This study describes our experience and a stepwise technical implementation of the laparoscopic pancreaticoduodenectomy (LPD) during early introduction in 2016. Methods: A team of three hepatopancreaticobiliary surgeons with extensive experience in open pancreaticoduodenectomy (OPD) and with advanced laparoscopic skills started a proctor-guided program with LPD. The first 20 carefully selected cases were prospectively reviewed and compared with a matched OPD cohort. Results: In 20 months, 20 minimally invasive PDs were performed. Reviewing the first 10 LPD cases, 7 patients (70%) had anastomosis-related complications, versus 16% in OPD (P = .001). After consulting an international LPD expert, the team switched to a hybrid technique consisting of LPD followed by open reconstruction through midline minilaparotomy (LPD-OR). In the following 10 cases of LPD-OR, no anastomosis-related complications did occur (P = .342 OPD versus LPD-OR). Conclusion: Safe introduction of new techniques in minimally invasive major abdominal surgery is imperative. Based on our single-center experience, LPD-OR may be safer in the earliest phase of the learning curve of minimally invasive PD, as part of a stepwise implementation toward the fully laparoscopic technique.

Randomized clinical trial of continuous transversus abdominis plane block, epidural or patient-controlled analgesia for patients undergoing laparoscopic colorectal cancer surgery

Background

The optimal analgesia regimen after laparoscopic colorectal cancer surgery is unclear. The aim of the study was to characterize the beneficial effects of continuous transversus abdominis plane (TAP) blocks initiated before operation on outcomes following laparoscopic colorectal cancer surgery.

Methods

Patients undergoing surgery for colorectal cancer were divided randomly into three groups: combined general–TAP anaesthesia (TAP group), combined general–thoracic epidural anaesthesia (TEA group) and standard general anaesthesia (GA group). The primary endpoint was duration of hospital stay. Secondary endpoints included gastrointestinal motility, pain scores and plasma levels of cytokines.

Results

In total, 180 patients were randomized and 165 completed the trial. The intention-to-treat analysis showed that duration of hospital stay was significantly longer in the TEA group than in the TAP and GA groups (median 4·1 (95 per cent c.i. 3·8 to 4·3) versus 3·1 (3·0 to 3·3) and versus 3·3 (3·2 to 3·6) days respectively; both P &lt; 0·001). Time to first flatus was earlier in the TAP group (P &lt; 0·001). Visual analogue scale (VAS) scores during coughing were lower in the TAP and TEA groups than the GA group (P &lt; 0·001). Raised plasma levels of vascular endothelial growth factor C, interleukin 6, adrenaline and cortisol were attenuated significantly by continuous TAP block.

Conclusion

Continuous TAP analgesia not only improved gastrointestinal motility but also shortened duration of hospital stay. A decreased opioid requirement and attenuating surgical stress response may be potential mechanisms. Registration number: ChiCTR-TRC-1800015535 (http://www.chictr.org.cn).

Oncologic and Perioperative Outcomes of Laparoscopic, Open, and Robotic Approaches for Rectal Cancer Resection: A Multicenter, Propensity Score-Weighted Cohort Study

BACKGROUND

Minimally invasive approaches have been shown to reduce surgical site complications without compromising oncologic outcomes.

OBJECTIVE

The primary aim of this study is to evaluate the rates of successful oncologic resection and postoperative outcomes among laparoscopic, open, and robotic approaches to rectal cancer resection.

DESIGN

This is a multicenter, quasiexperimental cohort study using propensity score weighting.

SETTINGS

Interventions were performed in hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program.

PATIENTS

Adult patients who underwent rectal cancer resection in 2016 were included.

MAIN OUTCOME MEASURES

The primary outcome was a composite variable indicating successful oncologic resection, defined as negative distal and radial margins with at least 12 lymph nodes evaluated.

RESULTS

Among 1028 rectal cancer resections, 206 (20%) were approached laparoscopically, 192 (18.7%) were approached robotically, and 630 (61.3%) were open. After propensity score weighting, there were no significant sociodemographic or preoperative clinical differences among subcohorts. Compared to the laparoscopic approach, open and robotic approaches were associated with a decreased likelihood of successful oncologic resection (ORadj = 0.64; 95% CI, 0.43-0.94 and ORadj = 0.60; 95% CI, 0.37-0.97), and the open approach was associated with an increased likelihood of surgical site complications (ORadj = 2.53; 95% CI, 1.61-3.959). Compared to the laparoscopic approach, the open approach was associated with longer length of stay (6.8 vs 8.6 days, p = 0.002).

LIMITATIONS

This was an observational cohort study using a preexisting clinical data set. Despite adjusted propensity score methodology, unmeasured confounding may contribute to our findings.

CONCLUSIONS

Resections that were approached laparoscopically were more likely to achieve oncologic success. Minimally invasive approaches did not lengthen operative times and provided benefits of reduced surgical site complications and decreased postoperative length of stay. Further studies are needed to clarify clinical outcomes and factors that influence the choice of approach. See Video Abstract at http://links.lww.com/DCR/B70. RESULTADOS ONCOLÓGICOS Y PERIOPERATORIOS DE LOS ABORDAJES LAPAROSCÓPICOS, ABIERTOS Y ROBÓTICOS PARA LA RESECCIÓN DEL CÁNCER RECTAL: UN ESTUDIO DE COHORTE MULTICÉNTRICO Y PONDERADO DEL PUNTAJE DE PROPENSIÓN: Se ha demostrado que los enfoques mínimamente invasivos reducen las complicaciones del sitio quirúrgico sin comprometer los resultados oncológicos.El objetivo principal de este estudio es evaluar las tasas de resección oncológica exitosa y los resultados postoperatorios entre los abordajes laparoscópico, abierto y robótico para la resección del cáncer rectal.Este es un estudio de cohorte cuasi-experimental multicéntrico que utiliza la ponderación de puntaje de propensión.Las intervenciones se realizaron en hospitales que participan en el Programa Nacional de Mejora de la Calidad Quirúrgica del Colegio Americano de Cirujanos.Se incluyeron pacientes adultos que se sometieron a resección de cáncer rectal en 2016.El resultado primario fue una variable compuesta que indicaba una resección oncológica exitosa, definida como márgenes negativos distales y radiales con al menos 12 ganglios linfáticos evaluados.Entre 1,028 resecciones de cáncer rectal, 206 (20%) fueron abordadas por vía laparoscópica, 192 (18.7%) robóticamente y 630 (61.3%) abiertas. Después de ponderar el puntaje de propensión, no hubo diferencias sociodemográficas o clínicas preoperatorias significativas entre las subcohortes. En comparación con el abordaje laparoscópico, los abordajes abiertos y robóticos se asociaron con una menor probabilidad de resección oncológica exitosa (ORadj = 0.64; IC 95%, 0.43-0.94 y ORadj = 0.60; IC 95%, 0.37-0.97), y el abordaje abierto se asoció con una mayor probabilidad de complicaciones del sitio quirúrgico (ORadj = 2.53; IC 95%, 1.61-3.959). En comparación con el abordaje laparoscópico, el abordaje abierto se asoció con una estadía más prolongada (6.8 frente a 8.6 días, p = 0.002).Este fue un estudio de cohorte observacional que utilizó un conjunto de datos clínicos preexistentes. A pesar de la metodología de puntuación de propensión ajustada, la confusión no medida puede contribuir a nuestros hallazgos.Las resecciones que se abordaron por vía laparoscópica tuvieron más probabilidades de lograr el éxito oncológico. Los enfoques mínimamente invasivos no alargaron los tiempos quirúrgicos y proporcionaron beneficios de la reducción de las complicaciones del sitio quirúrgico y la disminución de la duración de la estadía postoperatoria. Se necesitan más estudios para aclarar los resultados clínicos y los factores que influyen en la elección del enfoque. Vea video resumen en http://links.lww.com/DCR/B70.

Short-term efficacy of natural orifice specimen extraction surgery for low rectal cancer

BACKGROUND

This case-control study compared the short-term clinical efficacy of natural orifice specimen extraction surgery (NOSES) using a prolapsing technique and the conventional laparoscopic-assisted approach for low rectal cancer.

AIM

To further explore the application value of the transanal placement of the anvil and to evaluate the short-term efficacy of NOSES for resecting specimens of low rectal cancer, as well as to provide a theoretical basis for its extensive clinical application.

METHODS

From June 2015 to June 2018, 108 consecutive laparoscopic-assisted low rectal cancer resections were performed at our center. Among them, 26 specimens were resected transanally using a prolapsing technique (NOSES), and 82 specimens were resected through a conventional abdominal wall small incision (LAP). A propensity score matching method was used to select 26 pairs of matched patients, and their perioperative data were analyzed.

RESULTS

The baseline data were comparable between the two matched groups. All 52 patients underwent the surgery successfully. The operative time, blood loss, number of harvested lymph nodes, postoperative complication rate, circumferential margin involvement, postoperative follow-up data, and postoperative anal function were not statistically significant. The NOSES group had shorter time to gastrointestinal function recovery (2.6 ± 1.0 d vs 3.4 ± 0.9 d, P = 0.006), shorter postoperative hospital stay (7.1 ± 1.7 d vs 8.3 ± 1.1 d, P = 0.003), lower pain score (day 1: 2.7 ± 1.8 vs 4.6 ± 1.9, day 3: 2.0 ± 1.1 vs 4.1 ± 1.2, day 5: 1.7 ± 0.9 vs 3.3 ± 1.0, P < 0.001), a lower rate of additional analgesic use (11.5% vs 61.5%, P = 0.001), and a higher satisfaction rate in terms of the aesthetic appearance of the abdominal wall after surgery (100% vs 23.1%, P < 0.001).

CONCLUSION

NOSES for low rectal cancer can achieve satisfactory short-term efficacy and has advantages in reducing postoperative pain, shortening the length of postoperative hospital stay, and improving patients’ satisfaction in terms of a more aesthetic appearance of the abdominal wall.

Suprapubic single-port approach for complicated diverticulitis

BACKGROUND

Laparoscopic sigmoidectomy is the gold standard for elective surgical treatment of diverticulitis. A periumbilical single-port technique reduces the size of the access wound, usually to 3-4 cm. However, in the presence of large phlegmon or fistulae, the risk of conversion is higher and the extraction site might be enlarged. A suprapubic Pfannenstiel incision reduces the risk of incisional hernia compared to umbilical access and might provide the possibility to perform sigmoidectomy with a hybrid technique. The aim of the present study was to investigate the feasibility of laparoscopic sigmoidectomy through a single suprapubic transverse access for large diverticular phlegmon.

METHODS

Consecutive patients with a diverticular inflammatory mass ≥ 5 cm, with or without sigmoid-vesical fistula, were considered candidates for laparoscopic sigmoidectomy through a 5-cm single-port suprapubic (SPSP) access, extended (if required) to match the size of the inflammatory mass.

RESULTS

Twenty patients underwent SPSP sigmoidectomy at our institution in April 2014-April 2017. All procedures were completed by SPSP access, with no intraoperative complications or need for additional trocar placement. Eight patients had a sigmoid-vesical fistula (bladder sutured in three patients). The splenic flexure was mobilized in nine patients. Median operative time was 178 min and median hospital stay was 5.5 days (iqr 4-6). Postoperative complications occurred in four patients and included one subcutaneous hematoma, one urinary tract infection, and two superficial wound infections. After a median follow-up time of 25 months (interquartile range 15-38), all patients experienced complete resolution of symptoms, with no incisional hernias reported.

CONCLUSIONS

SPSP sigmoidectomy for diverticulitis is feasible and effective, minimizing the size of the access wound and avoiding increased risk of hernia. This approach might be especially valuable for the management of large diverticular phlegmon and sigmoid-vesical fistula.

Transversus abdominis plane (TAP) block in laparoscopic colorectal surgery improves postoperative pain management: a meta-analysis

AIM

Transversus abdominis plane (TAP) block is a locoregional anaesthesia technique of growing interest in abdominal surgery. However, its efficacy following laparoscopic colorectal surgery is still debated. This meta-analysis aimed to assess the efficacy of TAP block after laparoscopic colorectal surgery.

METHOD

All comparative studies focusing on TAP block after laparoscopic colorectal surgery have been systematically identified through the MEDLINE database, reviewed and included. Meta-analysis was performed according to the Mantel-Haenszel method for random effects. End-points included postoperative opioid consumption, morbidity, time to first bowel movement and length of hospital stay.

RESULTS

A total of 13 studies, including 7 randomized controlled trials, were included, comprising a total of 600 patients who underwent laparoscopic colorectal surgery with TAP block, compared with 762 patients without TAP block. Meta-analysis of these studies showed that TAP block was associated with a significantly reduced postoperative opioid consumption on the first day after surgery [weighted mean difference (WMD) -14.54 (-25.14; -3.94); P = 0.007] and a significantly shorter time to first bowel movement [WMD -0.53 (-0.61; -0.44); P < 0.001] but failed to show any impact on length of hospital stay [WMD -0.32 (-0.83; 0.20); P = 0.23] although no study considered length of stay as its primary outcome. Finally, TAP block was not associated with a significant increase in the postoperative overall complication rate [OR = 0.84 (0.62-1.14); P = 0.27].

CONCLUSION

Transversus abdominis plane (TAP) block in laparoscopic colorectal surgery improves postoperative opioid consumption and recovery of postoperative digestive function without any significant drawback.

Implementation of laparoscopic approach in colorectal surgery - a single center's experience

Introduction

Implementation of the laparoscopic approach in colorectal surgery has not happened as rapidly as in cholecystectomy, because of concerns about oncological safety. The results of controlled trials in multiple centers showed the method to be safe. Consequently, surgeons decided to try the approach with colorectal surgery. This process, in our clinic, began in earnest about four years ago.

Aim

To analyze and present the clinical outcomes of applying the laparoscopic approach to colorectal surgery in a single center.

Material and methods

We retrospectively identified patients from a hospital database who underwent colorectal surgery – laparoscopic and open – between 2013 and 2016. Our focus was on laparoscopic cases. Study points included operative time, duration of the hospital stay, postoperative mortality and rates of complications, conversion, reoperation and readmission.

Results

Of 534 cases considered, the results showed that the relation between open and laparoscopic procedures had reversed, in favor of the latter method (2013: open: 82% vs. laparoscopic: 18%; 2016: open: 22.4% vs. laparoscopic: 77.6%). The most commonly performed procedure was right hemicolectomy. The total complication rate was 22%. The total rate of conversion to open surgery was 9.3%. The postoperative mortality rate was 3%.

Conclusions

Use of the laparoscopic approach in colorectal surgery has increased in recent years world-wide – including in Poland – but the technique is still underused. Rapid implementation of the miniinvasive method in colorectal surgery, in centers with previous laparoscopic experience, is not only safe and feasible, but also highly recommended.

Mechanism of action of the atypical retinoid ST1926 in colorectal cancer: DNA damage and DNA polymerase α

Despite advances in therapeutic strategies, colorectal cancer (CRC) remains the third cause of cancer-related deaths with a relatively low survival rate. Resistance to standard chemotherapy represents a major hurdle in disease management; therefore, developing new therapeutic agents demands a thorough understanding of their mechanisms of action. One of these compounds is ST1926, an adamantyl retinoid that has shown potent antitumor activities in several human cancer models. Here, we show that ST1926 selectively suppressed the proliferation of CRC cells while sparing normal counterparts, and significantly reduced tumor volume in a xenograft cancer mouse model. Next, we investigated the effects of ST1926 in CRC cells and observed early DNA damage, S-phase arrest, dissipation of mitochondrial membrane potential, and apoptosis induction, in a p53 and p21-independent manner. To address the underlying mechanism of resistance to ST1926, we generated ST1926-resistant HCT116 cells and sequenced DNA polymerase α (POLA1), which was reported to be a direct target to the drug's parent molecule, CD437. We identified similar mutations in POLA1 that conferred resistance to ST1926 and CD437. These mutations were absent in 5-fluorouracil-resistant HCT116 cells, clearly validating the specificity of these mutations to the lack of DNA damage and acquired resistance to ST1926. ST1926 also inhibited POLA1 activity and reduced its protein expression levels. Further, in silico analysis of normal and malignant tissue expression data demonstrated that POLA1 levels are elevated in CRC cells and tissues compared to normal counterparts as well as to other cancer types. Our findings highlight previously uncharacterized mechanisms of action of ST1926 in CRC and suggest that elevated POLA1 expression is a pertinent molecular feature and an attractive target in CRC.

Robotics in general surgery: A systematic cost assessment

The utilisation of robotic-assisted techniques is a novelty in the field of general surgery. Our intention was to examine the up to date available literature on the cost assessment of robotic surgery of diverse operations in general surgery. PubMed and Scopus databases were searched in a systematic way to retrieve the included studies in our review. Thirty-one studies were retrieved, referring on a vast range of surgical operations. The mean cost for robotic, open and laparoscopic ranged from 2539 to 57,002, 7888 to 16,851 and 1799 to 50,408 Euros, respectively. The mean operative charges ranged from 273.74 to 13,670 Euros. More specifically, for the robotic and laparoscopic gastric fundoplication, the cost ranged from 1534 to 2257 and 657 to 763 Euros, respectively. For the robotic and laparoscopic colectomy, it ranged from 3739 to 17,080 and 3109 to 33,865 Euros, respectively. For the robotic and laparoscopic cholecystectomy, ranged from 1163.75 to 1291 and from 273.74 to 1223 Euros, respectively. The mean non-operative costs ranged from 900 to 48,796 from 8347 to 8800 and from 870 to 42,055 Euros, for robotic, open and laparoscopic technique, respectively. Conversions to laparotomy were present in 34/18,620 (0.18%) cases of laparoscopic and in 22/1488 (1.5%) cases of robotic technique. Duration of surgery robotic, open and laparoscopic ranged from 54.6 to 328.7, 129 to 234, and from 50.2 to 260 min, respectively. The present evidence reveals that robotic surgery, under specific conditions, has the potential to become cost-effective. Large number of cases, presence of industry competition and multidisciplinary team utilisation are some of the factors that could make more reasonable and cost-effective the robotic-assisted technique.

Impact of surgeon laparoscopic training and case volume of laparoscopic surgery on conversion during elective laparoscopic colorectal surgery

AIM

The study aimed to determine whether laparoscopic volume and type of training influence conversion during elective laparoscopic colorectal surgery.

METHOD

An Institutional Review Board-approved prospective database was reviewed for patients who underwent colorectal resection, performed by six colorectal surgeons, for all diagnoses from 2009 to 2014. Surgeons were designated as laparoscopic- or open-trained based on formal laparoscopic colorectal surgery training, and were classified as low laparoscopic volume (LLV) (i.e. had performed < 100 laparoscopic procedures) or high laparoscopic volume (HLV) (i.e. had performed ≥ 100 laparoscopic procedures). Technique was laparoscopic, open or converted (pre-emptive or reactive). Conversion was compared among three groups: LLV, laparoscopic trained (group A); LLV, open trained (group B); and HLV, open trained (group C).

RESULTS

In total, 159/567 procedures were open and 408 laparoscopic procedures were attempted. Of the 408 laparoscopic procedures, 73 were converted. Among the 567 patients [mean age: 56 ± 17 years (44% male)], the overall conversion rate was 13% (73/567), including 75% pre-emptive and 25% reactive. Conversion rates for groups A, B and C were 17.9%, 42.6% and 14.3%, respectively. Significantly higher conversion was seen in group B compared with group C (P = 0.01), but not between group A and group C (P = 0.85) or between group B and group A (P = 0.11). Converted patients were older (P < 0.001), with lower rates of proctectomy (P = 0.007), higher rates of anastomosis (P < 0.001) and higher body mass index (BMI) (P < 0.001). After adjusting for patient and surgeon factors, training type was not associated with conversion (P = 0.15). Compared with successful laparoscopy, converted patients had a significantly higher incidence of ileus (P < 0.001), length of stay (P = 0.002), time to flatus (OR = 3.21, P < 0.001) and time to solids (P < 0.001). Converted patients experienced increased morbidity.

CONCLUSION

Training is not associated with conversion. Rather, HLV surgeons, regardless of training, convert less frequently than do LLV surgeons.

Comparison of laparoscopic versus open gastrectomy for advanced gastric cancer: an updated meta-analysis

BACKGROUND

Laparoscopic gastrectomy (LG) has been used as an alternative to open gastrectomy (OG) to treat early gastric cancer. However, the use of LG for advanced gastric cancer (AGC) has been in debate.

METHODS

Literature retrieval was performed by searching PubMed, EMBASE, and the Cochrane library up to July 2014. Potential studies comparing the surgical effects between LG with OG were evaluated and data were extracted accordingly. Meta-analysis was carried out using RevMan. The pooled risk ratio and weighted mean difference (WMD) with 95 % confidence interval (95 % CI) were calculated.

RESULTS

Overall, 26 studies were included in this meta-analysis. LG had some advantages over OG, including shorter hospitalization (WMD, -3.63, 95 % CI, -4.66 to -2.60; P < 0.01), less blood loss (WMD, -161.37, 95 % CI, -192.55 to -130.18; P < 0.01), faster bowel recovery (WMD, -0.78, 95 % CI, -1.05 to -0.50; P < 0.01), and earlier ambulation (WMD, -0.95, 95 % CI, -1.47 to -0.44; P < 0.01). In terms of surgical and oncological safety, LG could achieve similar lymph nodes (WMD, -0.49, 95 % CI, -1.78 to 0.81; P = 0.46), a lower complication rate [odds ratio (OR), 0.71, 95 % CI, 0.59 to 0.87; P < 0.01], and overall survival (OS) and disease-free survival (DFS) comparable to OG.

CONCLUSIONS

For AGCs, LG appeared comparable with OG in short- and long-term results. Although more time was needed to perform LG, it had some advantages over OG in achieving faster postoperative recovery. Ongoing trials and future studies could help to clarify this controversial issue.

Surgery for Colorectal Cancer - Trends, Developments, and Future Perspectives

BACKGROUND

Although colorectal surgery is long established as the mainstay treatment for colon cancer, certain topics regarding technical fine-tuning to increase postsurgical recurrence-free survival have remained a matter of debate throughout the past years. These include complete mesocolic excision (CME), treatment strategies for metastatic disease, significance of hyperthermic intraperitoneal chemotherapy (HIPEC), and surgical techniques for the treatment of colorectal cancer recurrence. In addition, new surgical techniques have been introduced in oncologic colorectal surgery, and their potential to provide sufficiently radical resection has yet to be proven.

METHODS

A structured review of the literature was performed to identify the current state of the art with regard to the mentioned key issues in colorectal surgery.

RESULTS

This article provides a comprehensive review of the current literature addressing the above-mentioned current challenges in colorectal surgery. The focus lies on the impact of CME and, in relation to this, on lymph node dissection, as well as on treatment of metastatic disease including peritoneal spread, and finally on the treatment of recurrent disease.

CONCLUSION

Uniformly, the current literature reveals that surgery aiming at complete malignancy elimination within multimodal treatment approaches represents the fundamental quantum leap for the achievement of long-term tumor-free survival.

Large-Vessel Sealing in Laparoscopic Colectomy with an Ultrasonic Device

BACKGROUND AND OBJECTIVE

The Harmonic ACE+7 Shears with Advanced Hemostasis Mode (Ethicon, Somerville, NJ, USA) is an ultrasonic device designed to transect and seal vessels up to 7 mm in diameter. The device applies an algorithm that optimizes ultrasonic energy delivery combined with a longer sealing cycle. The purpose of this study was to assess the initial clinical experience with the Harmonic device by evaluating large-vessel sealing during laparoscopic colectomy in consecutive cases.

METHODS

This prospective, multicenter, observational series involved 40 adult patients who were to undergo elective laparoscopic colectomy where dissection and transection of the inferior mesenteric artery was indicated. The primary study endpoint was first-pass hemostasis, defined as a single activation of the Advanced Hemostasis Mode to transect and seal the inferior mesenteric artery. The use of any additional energy device or hemostatic product to establish or maintain hemostasis was noted. Patients were observed after surgery for ∼4 weeks for adverse events that were considered to be related to the study procedure or study device. Descriptive statistical analyses were performed for study endpoints.

RESULTS

Forty patients underwent the laparoscopic colectomy procedure. First-pass hemostasis of the inferior mesenteric artery was achieved and maintained in all 40 patients, with no required additional hemostatic measures. Exposure of the vessel was reported as skeletonized in 22 of 40 (55%) patients. Mean transection time was 21.9 ± 7.4 s. One adverse event (postoperative anemia) was considered possibly related to the study device.

CONCLUSION

In this initial clinical consecutive series, the device demonstrated successful transection and sealing of the large mesenteric vessels during laparoscopic colorectal surgery.

Laparoscopic colorectal surgery: Current status and implementation of the latest technological innovations

The introduction of laparoscopy is an example of surgical innovation with a rapid implementation in many areas of surgery. A large number of controlled studies and meta-analyses have shown that laparoscopic colorectal surgery is associated with the same benefits than other minimally invasive procedures, including lesser pain, earlier recovery of bowel transit and shorter hospital stay. On the other hand, despite initial concerns about oncological safety, well-designed prospective randomized multicentre trials have demonstrated that oncological outcomes of laparoscopy and open surgery are similar. Although the use of laparoscopy in colorectal surgery has increased in recent years, the percentages of patients treated with surgery using minimally invasive techniques are still reduced and there are also substantial differences among centres. It has been argued that the limiting factor for the use of laparoscopic procedures is the number of surgeons with adequate skills to perform a laparoscopic colectomy rather than the tumour of patients’ characteristics. In this regard, future efforts to increase the use of laparoscopic techniques in colorectal surgery will necessarily require more efforts in teaching surgeons. We here present a review of recent controversies of the use of laparoscopy in colorectal surgery, such as in rectal cancer operations, the possibility of reproducing complete mesocolon excision, and the benefits of intra-corporeal anastomosis after right hemicolectomy. We also describe the results of latest innovations such as single incision laparoscopic surgery, robotic surgery and natural orifice transluminal endoscopic surgery for colon and rectal diseases.
