Intraoperative transcystic laparoscopic common bile duct stone clearance with SpyGlass™ discover during emergency and elective cholecystectomy: a single-center case series.

BACKGROUND AND STUDY AIM: The development of a new cholangioscope, the SpyGlass™ Discover (Boston Scientific), has allowed the laparoscopic transcystic common bile duct exploration and stone clearance. The possibility of simultaneous treatment of choledocholithiasis during early laparoscopic cholecystectomy offers the opportunity to enormously reduce the time between acute cholecystitis diagnosis and the execution of cholecystectomy with better outcomes for patients. Furthermore, an altered anatomy of the gastrointestinal tract is not an obstacle to this technique. The aim of the study was to determine whether this new procedure is feasible, safe, and effective. PATIENTS AND METHODS: The investigation employs a retrospective case series study including all consecutive patients with a diagnosis of common bile duct stones undergoing cholecystectomy and intraoperative laparoscopic common bile duct clearance using SpyGlass™ Discover at IRCCS Policlinico San Matteo in Pavia (Italy). Eighteen patients were included from May 2022 to May 2023. RESULTS: A complete clearance of the common bile duct was obtained in 88.9% of patients. The mean postoperative length of stay was 3 days. No major complications occurred. After a median follow-up of 8 months, no recurrence of biliary events or readmissions occurred. CONCLUSION: This procedure has proven to be feasible, safe, and effective.

Saving from unnecessary pancreaticoduodenectomy. Brunner's gland hamartoma: Case report on a rare duodenal lesion and exhaustive literature review.

INTRODUCTION: Brunner's gland hamartoma (BGH) is an infrequently encountered, benign, polypoid proliferation of Brunner's glands. Usually these lesions are asymptomatic, just only occasionally presenting with duodenal obstruction or bleeding signs and mimicking a tumoral lesion. CASE PRESENTATION: A 72-year-old male, referred for recurrent vomiting and epigastralgia, was investigated and all preoperative findings were suggestive of a tumour of the duodenum. During the scheduled pancreaticoduodenectomy a mass, resultant to a polyp, was palpatory felt inside the duodenum and then successfully and completely resected through a duodenotomy avoiding surgical overtreatment and connected postoperative morbidities. Histological analysis showed hyperplasia of Brunner's glands correspondent to a Brunner's gland hamartoma. BGH was undiagnosed before surgery, due to its particular sub-mucosal growth simulating an expanding process starting from the duodenum, and secondly due to unsuccessful biopsies performed during endoscopic procedure. CONCLUSION: BGH is a rare lesion featuring, when symptomatic, obstructive or bleeding symptoms. Surgical treatment represents the gold standard approach in case of lesions that are technically impossible to remove endoscopically or in case of an undiagnosed lesion. Herein, we report a case of a patient presenting with a duodenal lesion mimicking, in all preoperative findings, a tumour of the duodenum. Duodenotomy and resection of the BGH provided a definitive cure avoiding surgical overtreatment. An intraoperative deep analysis of all surgical cases still remain crucial for a right therapeutic choice even in a new era for surgical technology. For similar intraoperative findings we recommend this technique.

Modified radical retropubic prostatectomy: personal technical variation "tension free continuum-urethral anastomosis (T.F.C.U.A)" with optical magnification in the preservation of the bladder neck, and estimation of the urinary continence.

OBJECTIVE: To reassess the double continence technique for open retropubic radical prostatectomy, proposed by Malizia and employed by Pagano et al., with the "tension free continuum-urethral anastomosis" (T.F.C.U.A.) personal modification and the use of image magnification optical systems and appropriate and delicate surgical tools. MATERIALS AND METHODS: A total of 173 radical retropubic prostatectomies, performed by the same surgeon, were evaluated in terms of early and late continence. RESULTS: The presence of residual prostate cancer cells within the muscle layer was always excluded by the histopathological examination that also demonstrated that the muscle layer was well represented; satisfactory outcomes were obtained in terms of both early urinary continence (60%) and urinary continence at 6-12 month follow-up (92.4% for the whole series and 97.2% for the last series of patients). CONCLUSIONS: The "tension free" anastomosis obtained by the suspension of the anterior bladder wall to the the pubis along the median line allowed to achieve satisfactory outcomes in terms of urinary continence, even if these data obviously need to be confirmed by other series and comparative trials.

The role of the elastography in the diagnosis of prostate cancer: a retrospective study on 460 patients.

OBJECTIVE: Prostate cancer is one of the most common cancer among men in industrialized total Prostatic Specific Antigen (PSA) and PSA ratio, Trans Rectal Ultrasound Scan (TRUS) and prostate biopsy, which is the gold standard for tumoral diagnosis. The poor sensibility of TRUS, when DRE and/or PSA are abnormal, requires prostate biopsy for diagnostic confirmation. The aim of this study was to evaluate the sensibility and the specificity of real time elastography (SE) with and without the association of TRUS for cancer diagnosis. MATERIAL AND METHODS: We retrospectively evaluated 460 patients who underwent TRUS-guided prostate biopsy. The mean age of patients was 66.4 years, the mean PSA was 7.96 ng/ml and the mean PSA ratio was 17.19%. We compared histopathological findings of prostate biopsies with the results of TRUS and elastography. RESULTS: 32.17% of all patients were positive for prostate cancer.TRUS showed a sensitivity of 76.35% with a low specificity (43.59%), a Positive Predictive Value (PPV) of 39.1% and a Negative Predictive Value (NPV) of 79.53%. SE showed a lower sensitivity (61.49%), but better specificity (75%), PPV (53.85%) and NPV (80.41%). The association of TRUS + SE showed an increase in the sensitivity (79.79%) and in the NPV (86.71%). We separately evaluated the results of the two urologists with a greater experience in the use of these diagnostic methods who got an excellent sensitivity (91.42%) and an high NPV (92.68%). CONCLUSIONS: SE is certainly an useful diagnostic method for the detection of prostate cancer, especially in association with TRUS. A great experience of the sonographist and an adequate training are indispensable to make, in the future, elastography a "structural marker".

Impact of intravesical hyaluronic acid and chondroitin sulfate on bladder pain syndrome/interstitial cystitis.

INTRODUCTION AND HYPOTHESIS: Intravesical instillations of hyaluronic acid (HA) and chondroitin sulfate (CS) may lead to regeneration of the damaged glycosaminoglycan layer in interstitial cystitis/bladder pain syndrome (IC/BPS). METHODS: Twenty-two patients with IC/BPS received intravesical instillations (40 ml) of sodium HA 1.6% and CS 2.0% in 0.9% saline solution (IALURIL, IBSA) once weekly for 8 weeks, then once every 2 weeks for the next 6 months. RESULTS: The score for urgency was reduced from 6.5 to 3.6 (p = 0.0001), with a reduction in pain scores from an average of 5.6 to 3.2 (p = 0.0001). The average urine volume increased from 129.7 to 162 ml (p < 0.0001), with a reduction in the number of voids in 24 h, from 14 to 11.6 (p < 0.0001). The IC Symptom and Problem Index decreased from 25.7 to 20.3 (p < 0.0001), and the Pain Urgency Frequency score, from 18.7 to 12.8 (p < 0.0001). CONCLUSION: The treatment appeared to be effective and well tolerated in IC/BPS in this initial experience.

[Real-time elastography in the diagnosis of prostate cancer: personal experience]. / Ruolo dell'elastosonografia prostatica transrettale nella diagnostica per immagini del carcinoma prostatico: esperienza personale.

INTRODUCTION: Prostate cancer is the most common cancer in men. In the future, a significant further increase in the incidence of prostate cancer is expected. The indication to perform a prostate biopsy is digital rectal examination suspicious for prostate cancer, total prostate specific antigen (PSA) value, free PSA/total PSA ratio, PSA density and PSA velocity, and an evidence of hypoechoic area at transrectal ultrasound scan. Unfortunately the specificity and sensibility are still poor. The aim of this retrospective study is to evaluate the specificity and sensibility of real time elastography versus ultrasound transrectal B-mode scan. METHODS: We retrospectively evaluated 108 pts. having undergone TRUS-guided transrectal prostate biopsy (10 samples). The indication for biopsy is: digital rectal examination, total prostate specific antigen (PSA) value, PSA ratio, PSA density and PSA velocity suspicious for prostate cancer, and/or an evidence of hypoechoic area at transrectal ultrasound scan, and/or hard area at real-time elastography. The mean age of patients is 66.8 years, mean PSA 6.5 ng/mL, and mean ratio 16.5%. We compared the histopathological findings of needle prostate biopsies with the results of transrectal ultrasound and transrectal real-time elastography. RESULTS: 32/108 (29.6%) pts. were positive for prostate cancer (mean Gleason score 7.08), mean PSA 14 ng/mL and mean ratio 9.5%. Transrectal ultrasound scan shows a sensibility of 69% and specificity of 68%. Transrectal ultrasound scan shows a VPP of 51.4%. Transrectal ultrasound scan shows a VPN of 80.9%. Real-time elastography shows a sensibility of 56% and specificity of 85.7%. Real-time elastography shows a VPP of 60.1%. Real-time elastography shows a VPN of 83%. CONCLUSIONS: Elastography has a significantly higher specificity for the detection of prostate cancer than the conventionally used examinations including DRE and TRUS. It is a useful real-time diagnostic method because it is not invasive, and simultaneous evaluation is possible while performing TRUS.
