Short-term and Medium-term Outcomes of Low Midline and Low Transverse Incisions in Laparoscopic Rectal Cancer Surgery

Comparison between liquid skin adhesive and wound closure strip for skin closure after subcuticular suturing in single-port laparoscopic appendectomy: a single-center retrospective study in Korea

Purpose

This study was performed to evaluate the safety and feasibility of skin adhesives and to compare postoperative and cosmetic outcomes after wound closure in single-port laparoscopic appendectomy (SPLA) between skin adhesives and steri-strips.

Methods

This was a single-center retrospective study. We included 22 and 47 patients in whom skin adhesive and steri-strips were used respectively, for skin closure after subcuticular suturing in SPLA between August 2014 and 2020. The patient scar assessment questionnaire (PSAQ) was completed postoperatively to assess postoperative cosmetic outcomes.

Results

On the postoperative day, patients in whom skin adhesive was used had significantly lower numeric rating scores than in whom steri-strips were used (2.8 ± 0.8 vs. 3.9 ± 0.8, p < 0.001). The frequency of analgesic administration within 24 hours and between 24 and 48 hours after surgery was significantly lower in the skin adhesive group compared to the wound closure strip group (1.4 ± 0.8 vs. 2.7 ± 1.2, p = 0.013 and 0.2 ± 0.4 vs. 0.7 ± 0.9, p = 0.002, respectively). In the PSAQ, "satisfaction with appearance" and "satisfaction with symptoms" subitem scores were significantly lower in patients in whom skin adhesive was used (11.3 ± 3.0 vs. 15.1 ± 4.5, p = 0.006 and 6.5 ± 1.8 vs. 9.5 ± 3.3, p = 0.003), whereas, "appearance" and "consciousness" subitems revealed no statistically significant differences between the groups.

Conclusion

Liquid skin adhesive closures seem to be safe and feasible and cause less postoperative pain, resulting in greater patient satisfaction with postoperative scars than wound closure strip closure after subcuticular suturing in SPLA.

Choice of specimen's extraction site affects wound morbidity in laparoscopic colorectal cancer surgery

BACKGROUND

The choice for an ideal site of specimen extraction following laparoscopic colorectal surgery remains debatable. However, midline incision (MI) is usually employed for right and left-sided colonic resections while left iliac fossa or suprapubic transverse incision (STI) were reserved for sigmoid and rectal cancer resections.

OBJECTIVE

To compare the incidence of surgical site infection (SSI) and incisional hernia (IH) in elective laparoscopic colorectal surgery for cancer and specimen extraction via MI or STI.

METHOD

Prospectively collected data of elective laparoscopic colorectal cancer resections between January 2017 and December 2019 were retrospectively reviewed. MI was employed for right and left-sided colonic resections while STI was used for sigmoid and rectal resections. SSI is defined according to the US CDC criteria. IH was diagnosed clinically and confirmed by CT scan at 1 year.

RESULTS

A total of 168 patients underwent elective laparoscopic colorectal resections. MI was used in 90 patients while 78 patients had STI as an extraction site. Demographic and preoperative data is similar for two groups. The rate of IH was 13.3% for MI and 0% in the STI (p = 0.001). SSI was seen in 16.7% of MI vs 11.5% of STI (p = 0.34). Univariate and multivariate analysis showed that the choice of extraction site is associated with statistically significant higher incisional hernia rate.

CONCLUSION

MI for specimen extraction is associated with higher incidence of both SSI and IH. The choice of incision for extraction site is an independent predicative factor for significantly higher IH and increased SSI rates.

An evidence map and synthesis review with meta-analysis on the risk of incisional hernia in colorectal surgery with standard closure

PURPOSE

To assess the incidence of incisional hernia (IH) across various type of incisions in colorectal surgery (CS) creating a map of evidence to define research trends, gaps and areas of future interest.

METHODS

Systematic review of PubMed and Scopus from 2010 onwards. Studies included both open (OS) and laparoscopic (LS). The primary outcome was incidence of IH 12 months after index procedure, secondary outcomes were the study features and their influence on reported proportion of IH. Random effects models were used to calculate pooled proportions. Meta-regression models were performed to explore heterogeneity.

RESULTS

Ninetyone studies were included reporting 6473 IH. The pooled proportions of IH for OS were 0.35 (95% CI 0.27-0.44) I² 0% in midline laparotomies and 0.02 (95% CI 0.00-0.07), I² 52% for off-midline. In case of LS the pooled proportion of IH for midline extraction sites were 0.10 (95% CI 0.07-0.16), I² 58% and 0.04 (95% CI 0.03-0.06), I² 86% in case of off-midline. In Port-site IH was 0.02 (95% CI 0.01-0.04), I² 82%, and for single incision surgery (SILS) of 0.06-95% CI 0.02-0.15, I² 81%. In case of stoma reversal sites was 0.20 (95% CI 0.16-0.24).

CONCLUSION

Midline laparotomies and stoma reversal sites are at high risk for IH and should be considered in research of preventive strategies of closure. After laparoscopic approach IH happens mainly by extraction sites incisions specially midline and also represent an important area of analysis.
