Risk factors for prolonged operative time in single-incision laparoscopic cholecystectomy

Optimal indication of single-incision laparoscopic cholecystectomy using Konyang Standard Method in benign gallbladder diseases

Purpose

The optimal indications for single-incision laparoscopic cholecystectomy (SILC) have not yet been established.

Methods

This single-center retrospective study included consecutive patients who underwent SILC between April 2010 and June 2020. Difficult surgery (DS) (conversion to multiport or open cholecystectomy, adjacent organ injury, operation time of ≥90 minutes, or estimated blood loss of ≥100 mL) and poor postoperative outcome (PPO) (postoperative hospital stay ≥ 7 days or Clavien-Dindo grade ≥ II postoperative complications) were defined to comprehensively evaluate surgical difficulty and postoperative outcomes, respectively.

Results

Of 1,405 patients (mean age, 51.2 years; 802 female [57.1%]), 427 (grade I, n = 358; grade II/III, n = 69) underwent SILC for acute cholecystitis (AC), 34 (2.4%) needed conversion to multiport (n = 33) or open cholecystectomy (n = 1), 7 (0.5%) had adjacent organ injury during surgery, and 49 (3.5%) developed postoperative complications. Of the patients, 89 and 52 had DS and PPO, respectively. In the multivariate analysis, grade I AC, grade II/III AC, and body mass index of ≥30 kg/m² were significant predictors of DS. Age of ≥70 years and DS were significant predictors of PPO. In a subgroup analysis of patients with AC, DS (9.5% vs. 27.5%, p < 0.001) and PPO (5.0% vs. 15.9%, p = 0.001) were more frequent in patients with grade II/III AC than in those with grade I AC.

Conclusion

SILC is not recommended in patients with grade II/III AC and should be carefully performed by experienced and well-trained surgeons.

A Comparative Study of Needlescopic Grasper Assisted Single Incision versus Three-Port versus Pure Single Incision Laparoscopic Cholecystectomy

Purpose

Single incision laparoscopic cholecystectomy (SILC) is a surgical method to treat gallbladder disease designed to reduce postoperative pain and improve cosmetic results. However, pure SILC (pSILC) has several inherent limitations. In this study, we report the surgical outcomes of SILC with needlescopic grasper (nSILC) compared with those of pSILC and conventional three-port laparoscopic cholecystectomy (TPLC).

Methods

This retrospective study enrolled 103 patients who underwent laparoscopic cholecystectomy for benign gallbladder disease in our hospital between January 2013 and January 2015. Among them, 33 patients underwent pSILC, 35 underwent nSILC, and 35 underwent TPLC. We collected demographic characteristics and operative data to analyze outcomes between groups.

Results

All procedures were done by laparoscopy and the gallbladder of each patient was completely removed. Women and younger patients were more to undergo SILC than TPLC. Analysis showed that the operation time of the nSILC group was longer than that of the TPLC group, but shorter than that of the pSILC group (skin to skin operation time [pSILC: 65.2±19.1 min, nSILC: 49.7±12.9 min, and TPLC: 43.4±14.7 min, p<0.001], and major procedure time [pSILC: 42.2±18.7 min, nSILC: 25.9±8.9 min, and TPLC: 23.4±12.7 min, p<0.001]). There were no significant differences between the groups for patient visual analogue scale score, length of hospital stay, or intraoperative blood loss.

Conclusion

nSILC is feasible surgical method in patients with benign gallbladder disease compared to TPLC, and that is an effective procedure to overcome the disadvantage of pSILC.

A promising technique for easier single incision laparoscopic cholecystectomy: needle grasper traction of gallbladder

Introduction

Laparoscopic cholecystectomy (LC) is the primary treatment method for benign gallbladder diseases. Single incision laparoscopic cholecystectomy (SILC) was reported to be superior in terms of work return, cosmetic results, and post-operative pain, but limited maneuver capacity and overlapping of hand tools are technical difficulties associated with SILC that endanger patient safety.

Aim

To perform SILC using a needle grasper for gallbladder traction, thus simplifying the dissection of Calot's triangle.

Material and methods

The files of patients who underwent elective LC for gallbladder stone and polyps in general surgery clinics between December 2013 and December 2014 were analyzed retrospectively. The patients were divided into two groups: needle-grasper-assisted SILC (nSILC) and conventional laparoscopic cholecystectomy (CLC). Age, gender, height, weight, body mass index, visual analog scale (VAS) scores, ASA score, duration of operation, duration of post-operative hospital stay, complications, drain use, conversion to open and conventional technique, and oral feeding beginning time were analyzed.

Results

There were no per-operative or post-operative complications in either of the groups, and no significant differences were found between the groups in terms of complications. The mean duration of the operation was significantly longer in the nSILC group. There was no difference between the groups in terms of hospital stay. The mean visual analogue scale (VAS) scores in conventional nSILC were significantly lower for all hours. The patient satisfaction in terms of cosmetic results was better in the nSILC group.

Conclusions

Needle-grasper-assisted SILC reduces the number of tools that need to be held by surgeons; it also provides safe dissection, better cosmetic results, and less post-operative pain in elective cases.

Single center experiences of needle-scopic grasper assisted single incision laparoscopic cholecystectomy for gallbladder benign disease: comparison with conventional 3-port laparoscopic cholecystectomy

Purpose

Single incision laparoscopic cholecystectomy (SILC) has some technical problems. Our group has performed needlescopic grasper assisted SILC (nSILC) to overcome these problems. In this study, we introduce our technique and evaluate the safety and feasibility of this technique compared with the conventional laparoscopic cholecystectomy (CLC).

Methods

The medical records of 485 patients who received nSILC and CLC were reviewed retrospectively. Surgical outcomes including operative time, hospital stay, postoperative pain and perioperative complication were compared between the 2 techniques.

Results

Although wound complications were developed more frequently in nSILC group, there was no significant difference between groups in other surgical outcomes. In subgroup analysis, surgical outcomes of nSILC were similar with those of CLC not only in easy group but also in difficult group.

Conclusion

It seems that nSILC is safe and feasible not only in selected patients but also in difficult cases such as acute cholecystitis.
