The Effect of the Degree of Histologic Inflammation on Gallbladder Perforation During Laparoscopic Cholecystectomy

Effectiveness of no drainage after elective day-case laparoscopic cholecystectomy, even with intraoperative gallbladder perforation: a randomized controlled trial

BACKGROUND

Laparoscopic cholecystectomy (LC) has been carried out as day-case surgery. Current guidelines do not mention the role of drainage after LC. In particular, data stay blank with no prospective study on drainage management when gallbladder perforation (GP) accidentally occurs intraoperatively.

METHODS

A randomized controlled trial was conducted to compare clinical outcomes of drainage and no drainage after elective day-case LC. Intraoperative GP was recorded. The primary and secondary outcomes were major and minor complications, respectively.

RESULTS

Two hundred patients were randomized. No major complications occurred in either group. In secondary outcomes, nausea/vomiting, pain, hospital stay, and cost were similar in the drainage group and no drainage group; postoperative fever, WBC, and CRP levels were significantly lower in the no drainage group. GP occurred in 32 patients. Male patients with higher BMI and CRP and abdominal pain within 1 month were more likely to occur GP. Subgroup analysis of GP, primary outcomes, and most secondary outcomes had no difference. Postoperative WBC and CRP were higher in the drainage group. Postoperative fever occurred in 63 patients. Univariate analysis of fever showed that blood loss, drainage, postoperative WBC, CRP, and hospital stay were significant. Multivariable logistic regression analysis demonstrated that drainage was an independent risk factor for fever after LC (OR 3.418, 95% CI 1.392-8.390; p = 0.007).

CONCLUSIONS

No drainage after elective day-case LC is safe and associated with fewer complications, even in intraoperative GP. The trial proves that drainage is an independent risk factor for postoperative fever. The use of a drain after LC may lead to an unsuccessful day-case procedure by causing fever, elevated CRP, and extended hospital stay (NCT03909360).

Feasibility and safety of single-incision laparoscopic cholecystectomy versus conventional laparoscopic cholecystectomy in an ambulatory setting

BACKGROUND

Single-incision laparoscopic surgery has emerged as an alternative to conventional laparoscopic cholecystectomy (LC) in the clinical setting. Limited information is available on the possibility of performing single-incision laparoscopic surgery as an ambulatory procedure. This study aimed to determine the feasibility and safety of single-incision laparoscopic cholecystectomy (SILC) versus conventional LC in an ambulatory setting.

METHODS

Ninety-one patients were randomized to SILC (n = 49) or LC (n = 42). The success rate, operative duration, blood loss, hospital stay, gallbladder perforation, drainage, delayed discharge, readmission, total cost, complications, pain score, vomiting, and cosmetic satisfaction of the two groups were then compared.

RESULTS

There were significant differences in the operative time (46.89 ± 10.03 min in SILC vs. 37.24 ± 10.23 min in LC; P < 0.001). As compared with LC, SILC was associated with lower total costs (8012.28 ± 752.67 RMB vs. 10258.91 ± 1087.63 RMB; P < 0.001) and better cosmetic satisfaction (4.94 ± 0.24 vs. 4.74 ± 0.54; P = 0.031). There were no significant differences between-group in terms of general data, success rate, blood loss, hospital stay, gallbladder perforation, drainage, delayed discharge, readmission, complications, pain score, and vomiting (P > 0.05).

CONCLUSIONS

Ambulatory SILC is safe and feasible for selected patients. The advantages of SILC as compared with LC are improved cosmetic satisfaction and lower total costs.

Does the Difficulty of Laparoscopic Cholecystectomy Differ Between Genders?

Some studies have shown that severe fibrosis and anatomical anomalies are more common in men, and subsequently, laparoscopic cholecystectomy is more difficult in male than female patients. We aimed to evaluate the effect of gender in patients who underwent laparoscopic cholecystectomy, with regard to the conversion rate, the differences in histological inflammation severity, and anatomical difficulty. We reviewed retrospectively 915 patients with symptomatic cholelithiasis who underwent laparoscopic cholecystectomy in the First Department of General Surgery at Vakif Gureba Training and Research Hospital. Patients were divided into male (group 1) and female (group 2) groups. Both groups were compared with demographic criteria, the type of inflammation found on resected gallbladder, anatomical difficulty, gallbladder perforation during the operation, length of operation time, conversion rate, and omental and organ adhesions to the gallbladder. Of the 915 patients, 173 patients (19 %) were males (group 1), and 742 (81 %) were females (group 2). Mean age was 53 ± 12 (range 22 to 80) years in group 1 and 49 ± 13 (range 17 to 85) years in group 2. The average duration of surgery was 71 ± 33 min (range 20 to 160) in group 1 and 58 ± 27 min (range 15 to 135) in group 2 (p < 0.001). The conversion rate between groups was significantly different (p < 0.05). Inflammatory findings (acute or chronic) in resected gallbladder between groups 1 and 2 were significantly different (p < 0.0001 and p < 0.05, respectively). The frequency of adhesions between the gallbladder and omentum and other organs was higher in male (p = 0.003 and p = 0.0006, respectively). Anatomical difficulty was more prominent in male patients (p < 0.0001). The findings of higher scores of anatomical difficulty in operation and inflammation in cholecystectomy specimens, as well as higher rates of conversion in males, suggested that laparoscopic gallbladder surgery is more difficult in men.
