Transrectal specimen extraction after laparoscopic left colectomy: a case‐matched study

Abstract

Transrectal specimen extraction after left colectomy using the circular stapler technique is feasible. A side-to-end anastomosis appears safer than an end-to-end anastomosis. Further studies are needed to explore the potential advantages of this procedure over CL.

Meta-analysis of hybrid natural-orifice transluminal endoscopic surgery versus laparoscopic surgery

“…For non‐randomized trials, a median of 5 of 9 stars were awarded (range 4–9). There was one non‐RCT with a matched concurrent control, five with a non‐matched concurrent control, six with a matched historical control, one with a non‐matched historical control and eight retrospective non‐randomized trials. The quality rating of the included non‐randomized studies is shown in Table .…”

Laparoscopic resection with natural orifice specimen extraction versus conventional laparoscopy for colorectal disease: a meta-analysis

“…Third, differences in the baseline characteristics of patients between the NOSE group and CL group may have contributed to heterogeneity that we could not eliminate. For instance, Christoforids et al [23] enrolled more older patients in the CL group (p=0.05), and Costantino et al [16] enrolled patients with higher BMI and American Society of Anesthesiologists score in the control group (p<0.01; p=0.08). Finally, differences in the skill of the operating surgeon, operating technique, and methods of measurement of outcomes between included studies may have provided bias that we could not avoid or control.…”

“…After reading titles and abstracts, 21 studies were shown to be pertinent. Finally, nine studies [16,[22][23][24][25][26][27][28][29] were found to fit the inclusion criteria after reading the full text (Fig. 1).…”

“…Seven studies [22][23][24][26][27][28][29] reported the operation time. The NOSE group showed a significantly longer operation time than the CL group (WMD = 20.97 min, 95 % CI [4.33, 37.62], p=0.01).…”

Specimen retrieval approaches in patients undergoing laparoscopic colorectal resections: a literature-based review of published studies

“…This approach was published in two comparative studies [48, 49], in which 68 patients underwent LCR for benign colorectal conditions (Table 4). Statistically, the duration of operation [Standardized Mean Difference (SMD) 1.81; 95% CI -1.99–5.62; Z = 0.93; P = 0.35] and risk of incisional hernia (OR 6.46; 95% CI 0.24–174.08; Z = 1.11; P = 0.27) were similar (SMD 1.81; 95% CI -1.99–5.62; Z = 0.93; P = 0.35) in both approaches.…”
