New advantageous tool in single incision laparoscopic cholecystectomy: the needle grasper

Laparoscopic surgery and robotic surgery for single-incision cholecystectomy: an updated systematic review

The role of single-incision laparoscopic cholecystectomy (SILC) and single-incision robotic cholecystectomy (SIRC) is still unclear. We update the summarization of the feasibility and safety of SILC and SIRC. A comprehensive search of SILC and SIRC of English literature published on PubMed database between January 2015 and November 2020 was performed. A total of 70 articles were included: 41 covering SILC alone, 21 showing SIRC alone, 7 reporting both, and 1 study not specified. In total, 7828 cases were recorded (SILC/SIRC/not specified, 6234/1544/50); and the gender of 7423 cases was definitively reported: the female rate was 64.0% (SILC/SIRC/not specified, 62.1%/71.5%/74.0%). The weighted mean for body mass index (BMI), operative time, blood loss and post-operative hospital stay was 25.5 kg/m² (SILC/SIRC, 25.0/27.0 kg/m²), 73.8 min (SILC/SIRC, 68.2/88.8 min), 12.6 mL (SILC/SIRC, 12.1/14.8 mL) and 2.5 days (SILC/SIRC, 2.8/1.9 days), respectively. The pooled prevalence of an additional port, conversion to open surgery, post-operative complications, intraoperative biliary injury, and incisional hernia was 4.1% (SILC/SIRC, 4.7%/1.9%), 0.9% (SILC/SIRC, 0.7%/1.5%), 5.9% (SILC/SIRC, 6.2%/4.1%), 0.1% (SILC/SIRC, 0.2%/0.09%), and 2.1% (SILC/SIRC, 1.4%/4.8%), respectively. Compared with conventional laparoscopic cholecystectomy, SIRC has experienced more postoperative incisional hernias (risk difference = 0.05, 95% confidence interval 0.02-0.07; P < 0.0001). By far, SILC and SIRC have not been considered a standard procedure. With the innovation of medical devices and gradual accumulation of surgical experience, feasibility and safety of performing SILC and SIRC will improve.

Transumbilical single-incision laparoscopic-assisted technique for removal of ileocecal foreign body

The aim of this paper is to present the case of a 40-year-old man who accidentally ingested a piece of metal. The patient complained of having intermittent right lower quadrant abdominal pain for 2 days. An abdominal X-ray was performed, and a piece of metal was found in the right lower quadrant of the abdomen. There was no gas in the abdominal cavity. Surgical treatment was therefore needed. Single-incision laparoscopic surgery (SILS) was attempted with conventional laparoscopic instruments. The foreign body was identified around the ileocecal region, an enterostomy was made and the foreign body was successfully removed. Subsequently, the incised ileocecal was wall sutured. The time for this surgery was 1 h with little bleeding. The patient made a quick recovery with a good cosmetic outcome. Based on this case, the use of SILS-assisted technique in the removal of an ileocecal foreign body proves to be safe and feasible.

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.

Unexpected pathological findings after laparoscopic cholecystectomy - analysis of 1131 cases

Introduction

Gallbladder specimens are routinely sent for histopathological examination after cholecystectomy in order to rule out the presence of unexpected pathological findings.

Aim

To establish the overall incidence of unexpected pathological findings in patients who underwent laparoscopic cholecystectomy for symptomatic gallbladder disease and determine whether the macroscopic appearance of the gallbladder in ultrasound examination could be a valid method for identifying patients with gallbladder malignancy.

Material and methods

A retrospective study was conducted between 2013 and 2015. All histological reports (n = 1131) after cholecystectomy were searched for unexpected pathological findings. In cases where unexpected pathological findings were identified the additional analysis of preoperative abdominal ultrasound examination (USG) was done to determine the usefulness of USG in diagnosis of gallbladder malignancy.

Results

Of the 1131 patients included in the study, 356 (31.47%) were male and 774 (68.43%) were female. Unexpected pathological findings were present in 21 cases. The overall incidence of unexpected pathological findings was 1.86%. Only in 5 patients were suspicious appearances of gallbladder observed in preoperative ultrasound examination. In 16 patients there was no suspicion of malignancy. The positive predictive value of USG was 0.238.

Conclusions

The incidence of unexpected pathological findings after laparoscopic cholecystectomy was 1.86%. Ultrasonography has low positive predictive value for identifying patients with malignant findings in a gallbladder specimen.
