Background: It is important to predict acute cholecystitis (AC) before a laparoscopic cholecystectomy because inflammation of the gallbladder predicts the need for open conversion and subsequent morbidity after a laparoscopic cholecystectomy.

Objectives: To create an index based on clinical, laboratory, and ultrasound criteria on admission that will predict AC on pathological examination in patients presenting acutely.

Methods: We retrospectively reviewed consecutive cases of emergency laparoscopic cholecystectomies conducted by three experienced surgeons between 1 October 2014 and 31 January 2018. Independent variables were age, sex, presenting symptoms, admission laboratory tests, and ultrasound findings. The outcome variable was AC on histological examination. An index was created from all variables that added significantly to the logistic regression analysis.

Results: Eight variables that contributed significantly to the model, included age, male sex, vomiting on admission, an increased proportion of neutrophils, a normal aspartate aminotransferase test, a normal serum amylase test result, a thick gall bladder wall, and pericholecystic fluid. An index of ≤ 2 to ≥ 8 created from those variables had a graded risk for AC of 1.8% to 92.0% with a c-statistic of 0.86 (95% confidence interval 0.81–0.91). Operating time and bleeding increased in those with a higher index.

Conclusions: An index including age, sex, symptoms, and selected laboratory results as well as ultrasound characteristics had an excellent graded risk in the prediction of histological AC that was associated with operating time and an increased risk of bleeding during the operation.

Background: The timing of interval laparoscopic cholecystectomy continues to be a matter of debate. 

Objectives: To evaluate the best timing for performing this procedure after an episode of acute cholecystitis. 

Methods: In this retrospective analysis, we divided 213 patients into three groups based on the time that elapsed since an episode of acute cholecystitis to surgery: Group I: 1–6 weeks, Group II: 6–12 weeks, Group III: > 12 weeks. 

Results: The mean operative time ranged from 50 to 62 minutes, complication rate from 2.6% to 5.9%, conversion rate from 2.6% to 10.8%, length of hospitalization from 1.55 to 2.2 days, and the 30 day readmission rate from 2.7% to 7.9%. There were no statistically significant differences between the study groups in the primary outcome parameters.

Conclusions: Due to the lack of statistically significant differences between the groups, interval laparoscopic cholecystectomy can be performed safely and without increasing the complication rate within 6 weeks following the acute episode as well as 12 weeks after. However, a trend towards higher conversion and complication rates was observed in Group II (6–12 weeks).

 

Background: Gallbladder (GB) cancer is rare. Most cases are incidentally found in specimens after a cholecystectomy. Cholelithiasis is almost always present when this diagnosis is made. Obesity is a known risk factor for gallstone formation and thus may be related to GB cancer. 

Objectives: To highlight the importance of evaluation of the gallbladder before surgery, resection of the gallbladder whenever required, and screening the resected tissue for malignancy.

Methods: We retrospectively queried a prospectively maintained database of all bariatric procedures during the last 8 years for cases of concomitant laparoscopic sleeve gastrectomy (LSG) and laparoscopic cholecystectomy (LC). Pathologic reports of the gallbladders were reviewed. Demographic data and perioperative parameters were documented. 

Results: Of 2708 patients reviewed, 1721 (63.55%) were females and 987 (36.45%) males. Excluded were 145 (5.35%) who had a previous cholecystectomy. Of the remaining 2563, 180 (7.02%) had symptomatic gallbladder disease and underwent LSG with LC. Of these, two females (BMI 53 kg/m² and BMI 47 kg/m², both age 60) were found by histological examination to have adenocarcinoma in their GB specimens (1.11%). Both were reoperated, which included partial hepatectomy of the GB bed, resection of the cystic stump, lymph node dissection, and resection of the port sites. One patient is doing well, with no evidence of disease at a postoperative follow-up of 4 years. The second patient had recurrent disease with peritoneal spread and ascites 20 months post-surgery and died 18 months later. 

Conclusions: GB cancer is a rare finding in cholecystectomy specimens. The incidence of this entity might be higher in obese older females owing to the higher incidence of cholelithiasis in these patients. 

 

Objectives: To describe a novel, hybrid technique combining SILS and conventional laparoscopy using minimal abdominal wall incisions.

Methods: Fifty patients diagnosed with symptomatic cholelithiasis were operated using two reusable 5 mm trocars inserted through a single 15 mm umbilical incision and a single 2–3 mm epigastric port. This technique was dubbed “minimal incision laparoscopic cholecystectomy” (MILC).

Results: MILC was completed in 49 patients (98%). In five patients an additional 3 mm trocar was used and in 2 patients the epigastric trocar was switched to a 5 mm trocar. The procedure was converted to CLC in one patient. Mean operative time was 29 minutes (range 18–60) and the average postoperative hospital stay was 22 hours (range 6–50). There were no postoperative complications and the cosmetic results were rated excellent by the patients.

Conclusions: MILC is an intuitive, easy-to-learn and reproducible technique and requires small changes from CLC. As such, MILC may be an attractive alternative, avoiding the cost and complexity drawbacks associated with SILS.

Background: Earlier studies comparing minilaparotomy cholecystectomy with laparoscopic cholecystectomy did not find significant differences between the MC[1] and the LC[2] groups in operating times and patients' recovery.

Objectives: To compare the postoperative quality of life between the MC and LC groups.

Methods: The 157 patients with uncomplicated symptomatic gallstones, confirmed by ultrasound, were randomized to two groups: 85 for MC and 72 for LC. The study was prospective and randomized but not blinded or consecutive. The study groups were similar in patients' age, gender, body mass index, American Association of Anesthesiology physical fitness classification, and the operating surgeon. Patients were reevaluated 4 weeks after operation using the RAND-36 quality of life questionnaire.

Results: The RAND-36 questionnaire did not identify statistically significant differences between the study groups in general health perceptions, physical functioning, emotional well-being, social functioning, energy, bodily pain, and role functioning/emotional. Only the role functioning/physical score was slightly higher in the LC group (P = 0.038).
Conclusions: The results of this study showed that the MC procedure is a good alternative to the LC procedure, when postoperative quality of life ia measured

Background: Carcinoma of the gallbladder is diagnosed in 0.3–1.5% of all cholecystectomy specimens.

Objectives: To establish the overall rate of gallbladder carcinoma and unexpected gallbladder carcinoma based on our experience.

Methods: We retrospectively evaluated all consecutive cholecystectomies performed in our ward during a 6 year period in order to determine the incidence of gallbladder carcinoma and to identify common characteristics of this particular group of patients.

Results: Of the 1,697 cholecystectomies performed in our ward during the 6 years, gallbladder carcinoma was diagnosed in six patients (0.35%), but was not suspected prior to surgery in any of them. In accordance with the literature, the occurrence in women (5/6) was higher than in men (1/6). The mean age was 70 years (range 55–90). The most common symptom was abdominal pain; the majority (5/6) had cholelithiasis, and the pathologic report confirmed the diagnosis of adenocarcinoma in all six patients.

Conclusions: The overall incidence of unsuspected gallbladder carcinoma in our series was 0.35%. We could not find any common characteristics for this particular group of patients when compared to patients with non-malignant pathology.
