Hand-assisted laparoscopic surgery compared with open resection for mid and low rectal cancer: a case-matched study with long-term follow-up

Surgical outcomes of hybrid hand-assisted laparoscopic pelvic exenteration for locally advanced rectal cancer: Initial experience

INTRODUCTION

Hybrid hand-assisted laparoscopic surgery (HALS) combines better visualization of laparoscopic surgery with the advantages of open surgery. The aim of this study was to describe important technical considerations of HALS and to assess the feasibility of hybrid HALS pelvic exenteration (PE) for primary advanced rectal cancer.

METHODS

From May 2012 to August 2018, we retrospectively analyzed 11 patients who underwent PE for primary advanced rectal cancer (< 10 cm from the anal verge). Patients were divided into the open PE group (n = 5) and the hybrid HALS PE group (n = 6).

RESULTS

There was no significant difference in patient characteristics between the two groups, and all included patients were male. Tumor invasion to adjacent organs was mostly anterior invasion. In addition, four patients (66%) in the hybrid HALS PE group and two (40%) in the open PE group received neoadjuvant therapy (P = .3).

CONCLUSION

Compared to open surgery, hybrid HALS has the advantages of less bleeding and less invasion, and can achieve the same results in the short-term. It was a reasonable procedure which was easy and safe dissection of internal iliac vessels and dorsal vein complex. Thus, hybrid HALS may become a useful approach for PE.

Outcomes of open, laparoscopic, and hand-assisted laparoscopic surgeries in elderly patients with right colon cancers: A case-control study

An increasing proportion of patients aged more than 70 years old are suffering from colorectal cancers. This study aimed to compare the short- and long-terms outcomes between open surgery (OS) or conventional laparoscopic surgery (LS) and hand-assisted laparoscopic surgery (HALS) in treatment of these elderly patients with right colon cancers.We retrospectively reviewed patients who underwent right colon resections for cancers in our institution between June, 2009 and December, 2014. Short- and long-terms outcomes including surgical endpoints, postsurgical recovery data, postoperative morbidity and mortality, overall survival and disease-free survival were compared among OS, LS, and HALS groups. All data were analyzed by SPSS 22.0.Finally, 69 consecutive patients (OS = 26, LS = 24, HALS = 19) with right colon cancers were included in the analysis. Compared with OS, HALS was associated with less time to first anus exhaust (P = .013), first liquid diet (P = .045), and first soft diet (P = .036). Meanwhile, there were significant less operative time (P = .0027), blood loss (P < .001), and less time to first liquid diet (P = .009) in HALS, compared with LS. In regards to long-term outcomes, there were no significant differences in overall survival and disease-free survival among the 3 groups.Compared with OS or LS, HALS may be more favorable in the treatment of elderly right colon cancers with decreased surgical time and postoperative recovery, and comparable cancer-specific survivals.

Long-Term Oncologic Outcomes of Minimally Invasive Proctectomy for Rectal Adenocarcinoma

BACKGROUND

Long-term oncologic outcomes after minimally invasive surgery (MIS) for rectal adenocarcinoma compared to open surgery continue to be debated. We aimed to review our high-volume single-institution outcomes in MIS rectal cancer surgery.

METHODS

A retrospective review of a prospectively collected database was completed of all consecutive adult patients with rectal adenocarcinoma treated from January 2005 through December 2011. Stage IV or recurrent disease was excluded. Demographics and operative and pathologic details were reviewed and reported. Primary endpoints include survival and recurrence.

RESULTS

A total of 324 patients were included and median follow-up was 54 months (IQR = 37.0, 78.8). The mean age was 58.2 ± 14.1 years. Tumors were in the upper rectum in 111 patients, mid-rectum in 113 patients, and lower rectum in 100 patients. Stage III disease was most common (49.4%). Overall conversion to open procedure rate was 13.9%. The circumferential radial margin was positive in only 1 patient (0.3%) and the mean lymph node yield was 24.7 ± 17.2. Cancer recurred in 42 patients (13%), 10 (2.5%) patients developed local recurrence, 32 (9.8%) developed distant metastasis, and 2 (0.6%) patients had both. The 5-year overall survival for stage 0, 1, 2, and 3 disease is 96, 91, 80, and 77%, respectively (p = 0.015).

CONCLUSION

In carefully selected rectal cancer patients treated with MIS, long-term outcomes of survival and recurrence appear to compare favorably to previously published series.

Defining Non-inferiority Margins for Quality of Surgical Resection for Rectal Cancer: A Delphi Consensus Study

INTRODUCTION

Quality of surgical resection metrics (QSRMs) have been used as surrogates for long-term oncologic outcomes in non-inferiority randomized clinical trials (RCTs) comparing laparoscopic and open surgery for rectal cancer. However, non-inferiority margins (Δ_NI) for QSRMs have not been previously defined.

METHODS

A two-round, web-based Delphi was used to define Δ_NI for four QSRMs: positive circumferential resection margin (CRM), incomplete plane of mesorectal excision (PME), positive distal resection margin (DRM), and a composite of these outcomes. Overall, 130 international experts in rectal cancer (68 surgeons, 20 medical oncologists, 16 radiation oncologists, and 26 pathologists) were invited to participate. Experts were presented with evidence syntheses summarizing the association between QSRMs and long-term outcomes, and pooled quality of surgical resection outcomes for open surgery, and were asked to provide Δ_NI for all outcomes balancing the risks and benefits of minimally invasive surgery.

RESULTS

Seventy-two experts participated: 57 completed the initial questionnaire and 58 completed the revised questionnaire, with 43 participating in both rounds. Consensus was reached for all individual QSRM Δ_NI but not for the composite. The mean (standard deviation) Δ_NI was an absolute difference of 2.33% (1.59%) for the proportion of positive CRMs when comparing surgical interventions for the treatment of rectal cancer: 2.85% (1.83%) for incomplete PME; 1.28% (1.13%) for positive DRMs; and 2.71% (2.28%) for the composite. However, opinions varied widely for the composite outcome.

CONCLUSIONS

Web-based Delphi processes are a feasible approach to generate Δ_NI to evaluate novel surgical interventions. The generated Δ_NI for QSRMs for rectal cancer can be used for future RCTs and non-inferiority meta-analyses.

Hand-assisted laparoscopic surgery versus conventional open surgery in intraoperative and postoperative outcomes for colorectal cancer: An updated systematic review and meta-analysis

AIM

This meta-analysis aims to compare hand-assisted laparoscopic surgery (HALS) and conventional open surgery (OS) for colorectal cancer (CRC) in terms of intraoperative and postoperative outcomes, and to explore the safety, feasibility of HALS for CRC surgery.

METHODS

A systematic literature search with no limits was performed in PubMed, Embase, and Medline. The last search was performed on April 23, 2017. The outcomes of interests included intraoperative outcomes (operative time, blood loss, length of incision, transfusion, and lymph nodes harvested), postoperative outcomes (length of hospital stay, length of postoperative hospital stay, time to first flatus, time to first liquid diet, time to first soft diet, time to first bowel movement, postoperative complications, reoperation, ileus, anastomotic leakage, wound infection, urinary complication, pulmonary infection, and mortality).

RESULTS

Fifteen articles published between 2007 and 2017 with a total of 1962 patients with CRC were included in our meta-analysis. HALS was associated with longer operative time, less blood loss, smaller length of incision, shorter hospital days and postoperative hospital days, less time to first flatus, less wound infection, and less postoperative complications. There was no difference in blood transfusion, lymph node harvested, time to first liquid or soft diet, time to first bowel movement, reoperation, ileus, anastomotic leakage, pulmonary infection, urinary complications, or mortality.

CONCLUSIONS

Our meta-analysis suggests that HALS in CRC surgery improves cosmesis and results in better postoperative recovery outcomes by reducing postoperative complications and hospital days. Furthermore, a large randomized control study is warranted to compare the short-term and long-term outcomes of those 2 techniques for CRC treatment.

Advances in Laparoscopic Colorectal Surgery

Laparoscopic colorectal surgery has now become widely adopted for the treatment of colorectal neoplasia, with steady increases in utilization over the past 15 years. Common minimally invasive techniques include multiport laparoscopy, single-incision laparoscopy, and hand-assisted laparoscopy, with the choice of technique depending on several patient and surgeon factors. Laparoscopic colorectal surgery involves a robust learning curve, and fellowship training often lays the foundation for a high-volume laparoscopic practice. This article provides a summary of the various techniques for laparoscopic colorectal surgery, including operative steps, the approach to difficult patients, and the learning curve for proficiency.

Current application and prospects of hand-assisted laparoscopic surgery in gastrointestinal tumors

Hand-assisted laparoscopic surgery (HALS) refers to operations in which the surgeon inserts his/her non-dominant hand through a specific auxiliary device into the peritoneal cavity to assist the laparoscopic instruments. Because there is one hand to assist in the operation, HALS can reduce the difficulty of operation and shorten operative time. Previously, HALS is considered the transitional bridge from the traditional open surgery to laparoscopic surgery, but now, HLAS, together with total laparoscopic surgery and laparoscopic assisted surgery, is considered three forms of routine laparoscopic surgery. Along with the extensive use of laparoscopic surgery in gastrointestinal tumors, HALS, as a new method of laparoscopic surgery, has been gradually used in gastrointestinal tumors in recent years.
