Laparoendoscopic single-site surgery in inguinal hernia repair

Technical, ergonomic and cognitive learning methodology in transumbilical single-port laparoscopic hysterectomy

OBJECTIVE

We introduced learning curves on a detailed step protocol and ergonomic aspect to determine key surgical points in transumbilical single-port laparoscopic hysterectomy (TSPLH) and to popularize both technical and cognitive methodology on laparoendoscopic single-site surgery (LESS).

MATERIALS AND METHODS

A retrospective analysis of 87 TSPLH procedures was conducted by a single surgeon in three learning stages. Technical, ergonomic, and cognitive steps were introduced, and surgical outcomes were analyzed.

RESULTS

Key production points in TSPLH include developing a clear retroperitoneal space, maintaining appropriate strength and direction with a vaginal manipulator, coagulating the uterine artery, and applying an improved vaginal stump suturing method. Technical factors included instrument domination, hand-eye coordination, and alternating hand functions. Ergonomic techniques focused on shoulder, elbow, arm, wrist, and finger movements, range of motion, muscle power, continuous forces, and flexibility. Improved cognitive factors such as confidence, decision-making, and communication were also observed.

CONCLUSIONS

The study aimed to form methodological education on TSPLH and LESS and benefit more surgeons. The detailed production and key ergonomic points will help guide self-learning and education.

Laparoendoscopic single-site inguinal lymphadenectomy in gynecology: preliminary experience at a single institution

PURPOSE

Laparoendoscopic single-site surgery (LESS), a promising innovation in minimally invasive surgery, has been used in treating gynecologic oncology diseases. There have been no reports in the literature regarding LESS for inguinal lymphadenectomy (LESS-IL) in gynecologic conditions. We aimed to evaluate the feasibility, safety, and outcomes of LESS-IL.

METHODS

Six patients with vulvar or vaginal cancer underwent LESS-IL from July 2018 to March 2019. Data regarding the intraoperative and postoperative outcomes were analyzed.

RESULTS

All patients successfully underwent a bilateral LESS-IL without conversion. LESS pelvic lymphadenectomy via an umbilical incision was also performed in a patient with vaginal cancer. The median operation time for the single-port laparoendoscopic inguinal lymphadenectomies was 105 min (range 70-134), with a median estimated blood loss of 108 ml (range 40-170). Median time of hospitalization was 7.5 days (range 5-10). A median of 11 (6-15) lymph nodes were dissected in a unilateral groin. The suction drains were removed after a median duration of 5 days (range 3-7). There were no skin-related or lymph-related postoperative complications. At a median follow-up period of 9 months, all the patients were alive and no recurrence was found.

CONCLUSION

LESS-IL is a feasible and safe technique for the surgical management of gynecologic cancers.

Current status of single-port versus multi-port approach in laparoscopic inguinal hernia mesh repair: an up-to-date systematic review and meta-analysis

A meta-analysis was conducted to provide an up-to-date comparison of single-port and multi-port approach, in laparoscopic inguinal hernia mesh repair. This meta-analysis was performed on the basis of the PRISMA guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. The electronic databases (MEDLINE, Web of Science and Cochrane Central Register of Controlled Clinical Trials) were systematically screened. Fixed Effects or Random Effects model was used, according to the Cochran Q test. In total 16 eligible studies were found. There was no statistically significant difference, regarding unilateral operation duration, between the two approaches, in TEP (OR - 4.61; 95% CI - 9.70, 0.47, p = 0.08) or TAPP (OR - 1.96; 95% CI - 4.89, 0.97, p = 0.19) procedures. Similarly, in both operative modalities, no superiority of either approach was proven, in terms of conversion rate (TEP OR 0.69, p = 0.48; TAPP OR 5.46, p = 0.31), length of hospital stay (TEP WMD 0.00, p = 0.76; TAPP WMD - 0.11, p = 0.42) and overall complication rate (TEP OR 1.10, p = 0.51; TAPP OR 0.74, p = 0.43). Overall, single-port and the established multi-port approach in inguinal hernia mesh repair, are equivalent, regarding the postoperative outcomes. Given several limitations, further RCTs, of higher methodological and quality level are required.

Needlescopic herniorrhaphy using one umbilical 5-mm trocar and two lateral 3-mm trocars: A case series

INTRODUCTION

Laparoscopic surgery has become a standard treatment for inguinal hernia, with it recently being characterized by the use of smaller instruments. However, reports on needlescopic transabdominal preperitoneal repair using one umbilical 5-mm and two lateral 3-mm trocars are extremely rare.

METHODS

Seven patients with unilateral inguinal hernia underwent this surgical procedure. A 5-mm trocar was inserted from the umbilical and two 3-mm trocars were inserted from the lateral. After dissection of the preperitoneal layer, a mesh was fixed using a tucker inserted from the umbilical 5-mm trocar while viewing through the 3-mm optics from the lateral trocar.

RESULTS

All procedures were completed without intraoperative complications and conversion to the conventional method. The surgical results of our needlescopic TAPP repair have been shown to not be inferior to those of the conventional method.

CONCLUSION

Our needlescopic herniorrhaphy using one umbilical 5-mm trocar and two lateral 3-mm trocars is minimally invasive hernia repair.
