Difficult laparoscopic cholecystectomy (DLC) is difficult to precisely predict before operation. This observational cohort study aimed to evaluate the predictive value of procalcitonin (PCT) for DLC in patients with acute cholecystitis (AC). A total of 115 patients were included in the study from January 2017 to April 2018. Multiple logistic regression and receiver-operating characteristic (ROC) were performed to evaluate the predictive value of PCT levels in DLC. Patients with DLC had significantly higher Tokyo Guidelines 2018 (TG18) grade ( P = 0.002) and levels of C-reactive protein (CRP) ( P = 0.007) and PCT ( P < 0.001). The cut-off value of PCT for predicting DLC was 1.50 ng/ml. The sensitivity and specificity were 91.3% (95% CI 78.3–97.1) and 76.8% (95% CI 64.8–85.8), respectively. The area under ROC curve was 92.7% (95% CI 88.2–97.3, P < 0.001). Our results suggested that PCT was a good predictor for DLC in the AC patients, but further research is necessary. Monitoring of PCT trends in AC patients may be useful for preoperative risk assessment.

Background: Gallbladder torsion is very rare and easily misdiagnosed as biliary disease. It is defined as the rotation of the gallbladder along the axis of the cystic pedicle on the mesentery. As gallbladder rotation involves the gallbladder artery, the blood supply is blocked, resulting in gallbladder ischemia and eventual necrosis. If misdiagnosis occurs and treatment is delayed, gallbladder torsion can develop into a lethal disease. The typical imaging features of gallbladder torsion in this case are a good learning resource for our young physicians, as well as providing a rare, unusual and typical case for our current literature database.Case Description: We present a rare case of gallbladder torsion in a 19-year-old man. The patient complained of sudden recurrent pain and discomfort in the right upper abdomen with vomiting for 12 hours.Abdominal ultrasound and computed tomography (CT) scan showed gallbladder enlargement and signs of acute cholecystitis in emergency examination, and there were no signs of cholecystolithiasis. Considering that the patient was a young male and the patients prefer conservative treatment, symptomatic treatment was given. However, there was no obvious effect after 1 day of medical treatment, but severe abdominal pain in the upper right quadrant continues to progress. Finally, the patient underwent laparoscopic cholecystectomy, and the gallbladder was found to be enlarged with ischemic necrosis, which was caused by gallbladder torsion. The patient recovered 2 days after surgery and was discharged without complications.Conclusions: Although the clinical manifestation is similar to that of typical acute calculous cholecystitis, gallbladder torsion can be diagnosed early through some special signs on imaging examination, such as distorted cystic duct signs ("beak and whirl" sign), gallbladder dilatation with gallbladder fossa effusion, and gallbladder in the horizontal position. These signs can help primary surgical treatment and prevent fatal complications such as gallbladder gangrene, perforation, and biliary peritonitis. Therefore, for inexperienced doctors, careful imaging features are required for the correct diagnosis of rare gallbladder torsion.

The EEL is a clinically safe and necessary choice for early diagnosis and treatment in IOH. EEL may improve the curative effect of IOH significantly.

Objective:To assess the therapeutic effects of emergency laparoscopic appendectomy (LA) in treating complicated appendicitis (CA) for elderly patients (defined as age >65 years).Methods:We conducted a retrospective study of 115 elderly patients with CA who underwent surgical therapy in the Affiliated Huizhou Hospital of Sun Yat-Sun University, Huizhou, Guangdong Province, China between September 2014 and August 2016. Of these, 59 patients consented to open appendectomy (OA), and LA was performed in the other 56 patients. The perioperative and follow-up variables of the 2 groups were analyzed.Results:The operative time in the LA group was longer than the OA group (LA: 70.5±16.0 min versus [vs.] OA: 59.3±12.0 min, p<0.001). The LA group had lower chances of incision infections (LA: 8.9% vs. OA: 28.8 %, p=0.007) and shorter hospital stay (LA: 6.1± 2.5 days vs. OA: 9.6±3.5 days, p<0.001). Return to soft diet (LA: 1.4 ± 0.8 days vs. OA: 3.0 ± 1.6 days, p<0.001) and time to out of bed (LA: 1.3±0.5 days vs. OA: 2.5±0.9 days, p<0.001) was faster in the LA group. The incidence of complications and 30-day readmission rate in the LA group was much lower than the OA group.Conclusion:Emergency LA in treating elderly patients with CA has the advantages of less trauma, definite curative effect, low complication rates, and fast recovery when compared with OA.

BackgroundClinically relevant postoperative pancreatic fistula (CR-POPF) remains the most common neopathy after pancreatoduodenectomy (PD). An ideal pancreaticoenterostomy (PE) which can effectively reduce the incidence of CR-POPF and its potential neopathy is needed. We aimed to assess the efficacy of our modified duct-to-mucosa PE in the PD.MethodFrom January 2011 to December 2017, 233 consecutive patients with PD were retrospectively included from Shenzhen People’s Hospital. After propensity score matching (PSM), there were 82 patients in both the modified duct-to-mucosa PE group (group A) and the conventional end-to-side inserting PE group (group B), respectively. The clinical course and the incidence of postoperative neopathy were compared between groups. Logistic regression method was utilized to analyze the association between PE approach and CR-POPF.ResultsThe PE time was shorter in group A (9.3 ± 1.8 min vs. 21.5 ± 2.8 min, P < 0.001). The group A had significantly lower incidence of severe neopathy (Clavien–Dindo grade > II) [7.3% (5/82) vs. 17.1% (14/82), P = 0.028] and incidence of CR-POPF [1.2% (1/82) vs. 19.5% (12/82), P < 0.001] than the group B. Our modified duct-to-mucosa PE technique was associated with a reduced risk for CR-POPF (OR, 0.11 [95% CI, 0.02–0.57]; P = 0.009) as compared with the conventional end-to-side inserting PE.ConclusionCompared with conventional end-to-side inserting PE, our modified duct-to-mucosa PE technique can effectively reduce the incidences of postoperative neopathy and CR-POPF.Trial registrationResearchregistry3877.

Background Currently, an increasing number of robotic major hepatectomies for hepatocellular carcinoma (HCC) are being performed. Despite the advantages of robotic surgery over laparoscopic procedures, studies comparing robotic with laparoscopic major hepatectomy in terms of short-term results remain scarce. This study was performed to compare robotic major hepatectomy and laparoscopic major hepatectomy in terms of their intraoperative and postoperative results. Methods Data regarding demographics and intraoperative and postoperative results of 131 patients undergoing robotic or laparoscopic major hepatectomy between January 2017 and March 2022 were retrieved from their medical records and compared between the two types of surgery. Results Between January 2017 and March 2022, 44 robotic major hepatectomies and 87 laparoscopic major hepatectomies were performed at the Department of Hepatobiliary and Pancreatic Surgery, Shenzhen People’s Hospital. Patients undergoing robotic major hepatectomy were not significantly different from those undergoing laparoscopic major hepatectomy in terms of age (P = 0.397), sex (P = 0.624), body mass index (BMI) (P = 0.118), alpha-fetoprotein (AFP) (P = 0.09), tumor size (P = 0.176), cirrhosis (P = 0.384), fatty liver (P = 0.162), preoperative antiviral treatment (P = 0.934), hepatitis B virus (HBV) DNA (P = 0.646) and operation type (P = 0.054). Robotic major hepatectomy was associated with a longer operation time (median: 255.5 versus 206.8 min; P < 0.001) and less estimated blood loss (median: 118.9 versus 197.0 ml; P = 0.002) than laparoscopic major hepatectomy. However, robotic major hepatectomy was not significantly different from laparoscopic major hepatectomy regarding length of postoperative hospital stay (P = 0.849), open conversion (P = 0.077), ICU stay (P = 0.866), postoperative massive abdominal bleeding (P = 1.00), portal vein thrombosis (P = 1.00), abdominal infection (P = 1.00), pulmonary infection (P = 1.00), pulmonary embolism (P = 1.00), cardiac complications (P = 1.00), liver failure (P = 1.00), kidney failure (P = 1.00), biliary leak (P = 1.00), positive resection margin (P = 1.00), 30-day mortality (P = 1.00) and 90-day mortality (P = 1.00). Conclusions Robotic major hepatectomy was as effective as laparoscopic surgery in terms of intraoperative and postoperative results but took longer and could more efficiently control intraoperative blood loss.
