Abstract:
Objectives: To evaluate the comparative outcomes of three-dimensional (3D) versus two-dimensional (2D) imaging during laparoscopic cholecystectomy.
Method(s): We conducted a systematic search of electronic information sources and bibliographic reference lists and applied a combination of free text and controlled vocabulary search adapted to thesaurus headings, search operators and limits. Procedure time, Calot’s triangle dissection time, gallbladder removal time, gallbladder perforation, intraoperative bleeding, postoperative complications, conversion to open and intraoperative errors were the evaluated outcome parameters.
Result(s): We identified 6 randomised controlled trials (RCT) reporting a total of 577 patients who underwent laparoscopic cholecystectomy using 3D (n = 282) or 2D (n = 295) imaging. The 3D imaging was associated with significantly shorter procedure time (MD – 4.23, 95% CI – 8.14 to – 0.32, p = 0.03), Calot’s triangle dissection time (MD – 4.19, 95% CI – 6.52 to – 1.86, p = 0.0004) and significantly lower risk of gallbladder perforation (RR 0.50, 95% CI 0.28-0.88, p = 0.02) compared to the 2D approach. No significant difference was found in gallbladder removal time (MD – 0.79, 95% CI – 2.24 to 0.66, p = 0.28), intraoperative bleeding (RR 1.14, 95% CI 0.68-1.90, p = 0.61), postoperative complications (RD – 0.01, 95% CI – 0.06 to 0.05, p = 0.85), conversion to open (RD 0.00, 95% CI – 0.02 to 0.03, p = 0.70) or intraoperative errors (RR 0.96, 95% CI 0.79-1.17, p = 0.70) between the two groups.
Conclusion(s): Although our findings suggest that the use of 3D imaging during laparoscopic cholecystectomy may be associated with significantly shorter procedure time, Calot’s triangle dissection time and gallbladder injury compared to the 2D imaging, the differences seem to be clinically insignificant. Moreover, both approaches carry s similar risk of postoperative morbidities. The impact of the surgeon’s level of experience and difficulty of the procedure on the outcomes of each imaging modality remains unknown.

Abstract:
Aims: NICE/AUGIS guidelines suggest performing cholecystectomies while ‘hot’ (within a week). There is a
significant risk of biliary injury and/or open procedure in severely inflamed gallbladders and subtotal
cholecystectomies have been suggested to prevent these. The objective of this article is to present short and
medium term outcomes of laparoscopic subtotal cholecystectomy (LSC) in a specialist upper GI and bariatric
unit.
Method(s): This study included all consecutive patients who underwent LSC between August 2014 and August
2018. Clinical notes were retrospectively analysed. Assessed parameters included demographics, urgency of
operation, method of stump closure, length of inpatient stay, biliary injury, post-op incidence of intervention or
re-operation and post-op complications.
Result(s): 20 patients underwent LSC comprising around 0.7% of all the gallbladder operations performed in
our unit during this period. Median age was 67.1 years. 15 (75%) of these operations were carried out as
elective. Stump was closed by absorbable sutures in 18 (90%) of these patients while endoloop was used in one. Median length of stay was 6.2 days. None of the patients had biliary injury on later follow up and 7 (35%)
patients required ERCP. Post-op complications included chronic abdominal pain, wound infection and bile leak
in 2 (10%), 1 (5%) and 1 (5%) patient respectively.
Conclusion(s): Laparoscopic subtotal cholecystectomy proved to have an acceptable profile of safety and
outcomes in our unit and data is comparable with already published literature. Increased incidence of LSC in
elective patients may highlight the significance of establishing a hot gallbladder service.
