Abstract


Background: Single-incision laparoscopic surgery (SILS) and single-incision plus one-port laparoscopic surgery (SILS+1) for colorectal cancer are considered to require long operative times, experienced surgeons, and advanced surgical techniques. However, these procedures are advantageous because they require both fewer ports and fewer surgeons.
Patients and methods: In the SILS procedure for colon cancer, a Lap Protector™ (LP; Hakkou Shoji, Japan) is inserted through a 2.5 cm transumbilical incision. Next, an EZ-Access (Hakkou Shoji, Japan) is mounted onto the LP, and three ports are made in the EZ-Access. In SILS+1 for rectal cancer, we use an extra incision in the lower quadrant for drainage from the beginning of the operation. Data from 849 patients who underwent elective surgery with SILS or SILS+1 for colorectal cancer were reviewed.
Results: In 808 patients who underwent a reduced-port procedure for colorectal cancer, the mean incision length was 2.91 cm. The average operative time was 198.2 minutes, and average intra-operative blood loss was 25.6 mL. Complications with a Clavien-Dindo classification of II or greater occurred in 63 patients (7.2%). Among 654 stage I-III colorectal cancer patients, 69 (10.6%) experienced postoperative relapse during the follow-up period of 42 months.
Conclusions: Our cumulative findings support the use of SILS or SILS+1 in patients with colorectal cancer. The long-term oncologic outcomes make them acceptable technical alternatives to conventional multiport laparoscopic colectomy. Further trials are still needed to fully document the non-cosmetic benefits.

Abstract


Aim: The purposes of this study were to create a “three-plane model” for laparoscopic right hemicolectomy and to compare short-term outcomes of anterior medial-to-lateral (aM-to-L) and caudal-to-cranial access by retroperitoneal tunneling (Ca-to-Cr), as described based on the three-plane model.
Methods: A three-plane model was developed to clarify the steps of an operation. Consecutive cases of right colon cancer were operated upon with an aM-to-L approach in the earlier period and then with a Ca-to-Cr approach, and postoperative outcomes were evaluated. Short-term results were compared.
Results: Sixty-two patients were divided into aM-to-L (n=29) and Ca-to-Cr (n=33) groups. The two groups did not differ in terms of the patients’ baseline characteristics. Median operative time was 220 min (IQR 190-260) for the aM-to-L group and 222.5 min (IQR 180-255) for the Ca-to-Cr group (p=0.73). Estimated blood loss was similar in both groups (p=0.13). Median length of hospital stay was 6 days (IQR 5-8) in the aM-to-L group and 7 days (IQR 6-9) in the Ca-to-Cr group (p=0.17). Median number of harvested lymph nodes was 45.5 (IQR 25-44.9) in the aM-to-L group and 30 (IQR 18-48.5) in the Ca-to-Cr group (p=0.34).
Conclusion: The approach used to reach the superior mesenteric vessels for laparoscopic right hemicolectomy with D3 lymph node dissection does not affect the short-term outcome of the operation. The present three-plane model gives surgeons additional insight to perform this operation.

Molecular-based Alternatives for Colorectal Cancer Screening during the COVID-19 Pandemic

Abstract


Due to the COVID-19 pandemic, important elective procedures, such as screening colonoscopy, have been delayed or cancelled, and there may be a very long waitlist for rescheduling once the moratorium is lifted. However, DNA-based stool sample tests may be useful for colorectal cancer screening when colonoscopy is not available. The aim of this review is to demonstrate the potential utility of enhanced DNA-based stool testing for colorectal cancer screening and diagnosis during crises that strain available healthcare resources, such as the current COVID-19 pandemic. This review shows that DNA-based stool sample tests have the potential to enable colorectal cancer screening to prioritize patients to elective colonoscopy procedures, the continued delay of which during the COVID-19 pandemic has already placed a burden on future elective procedures.
