Standardized approach to the conservative surgery of hepatic cystic echinococcosis: A prospective study.

OBJECTIVE: Surgery is the mainstay of hepatic cystic echinococcosis (HCE). The conservative surgery of HCE carries a non-negligible risk of recurrence and significant morbidity, dominated by Deep Surgical Site Infections (DSSI). To address these issues, we have improved and standardized this technique, which could reduce complications and achieve better postoperative outcomes. PATIENTS AND METHODS: We conducted a prospective study from June 2017 to June 2022 involving of patient operated using a standardized open technique for uncomplicated HCE at Habib Bourguiba University Hospital, Sfax, Tunisia. The aim was to obtain results at least similar to radical management in terms of DSSI. Patients with large cystobiliary fistulas or patients with complicated cysts were excluded. RESULTS: Fifty patients with 106 cysts were operated using the standardized technique comprising of liver mobilization, intraoperative ultrasound, systematic methylene blue injection to detect cystobiliary fistulas and omentoplasty. The median age of the patients was 44(semi-interquartile range: 16) years. The main symptom described by the patient was pain in 43 cases (86%). An abnormal liver test was found in 20 cases (40%). On imaging studies, the cyst had a median size of 7.4(3.0) cm. Cyst of the hepatic dome accounted for 38 cases (35.8%) with most cysts being situated in the right hemi-liver. Visual inspection of the cavity and Methylene blue testing allowed for the discovery of 57 cysts (53.7%) that had cystobiliary fistulas that were sutured. Omentoplasty was performed in 77 cysts (72.6%). Postoperatively, only 2 cases (1.9%) developed a DSSI in the form of an external bile leak with resolved with conservative management. No case of recurrence was found after a median follow-up of 24 months. CONCLUSION: The standardized conservative surgical technique, in selected patients, shows promise in reducing DSSI rates and overall morbidity, and achieve as equally good result as radical management.

Cystic Echinococcosis of the Liver: Correlation Between Intra-Operative Ultrasound and Pre-Operative Imaging.

Background: Imaging plays an essential role in the management of hepatic hydatid cysts (HCE). The objective of our study was to determine the correlation between pre-operative ultrasound, computed tomography (CT), and intra-operative ultrasound (IOUS) in studying the characteristics and complications of HCE. Patients and Methods: This was a prospective, descriptive, and analytical study conducted in the General Surgery Department of Habib Bourguiba Hospital in Sfax. The study included patients with HCE who underwent conservative surgery between April 2017 and June 2022. Results: We enrolled 49 patients with 94 cysts. At the end of our study, IOUS allowed for better detection of HCE (98.8%) regardless of the number of cysts per patient. IOUS and CT were accurate in studying the location of cysts (κ = 1), whereas pre-operative abdominal ultrasound was less efficient (κ = 0.870). IOUS was the best examination for detecting exocysts (κ = 0.961), studying daughter cysts (κ = 0.823), and exploring vascular relations, but it was less effective (κ = 0.523) in detecting calcifications. Regarding classifications, ultrasound and CT had similar results. However, IOUS was most reliable in differentiating between CE3b and CE4 types (κ = 0.653). Ultrasound, CT, and IOUS were not sensitive in detecting latent HCE suppurations and cystobiliary fistulas. Conclusions: Performing IOUS is essential to prevent recurrences and reduce post-operative morbidity.

Predictive factors of occult cystobiliary fistulas during conservative treatment of hepatic hydatid cyst: a prospective study.

BACKGROUND: Occult cystobiliary fistula (CBF) is a common complication of hepatic hydatid cyst (HHC). It is often the cause of high morbidity of conservative treatment of HHC. This study aimed to determine the predictive factors of occult CBF to establish the indications for the investigation and treatment of these CBFs. METHODS: This was a prospective study that included all operated HHCs over a 3-year period. HHCs complicated with large CBFs were not included in the study. Systematic cholecystectomy and methylene blue test for all cysts were performed. RESULTS: A total of 46 patients operated on with 113 cysts were included in this study. The median cyst size was 6.7 cm (IQR, 1-38). A total of 114 CBFs were detected in 51 cysts (45.1%). The postoperative course was simple in 95.0% of cases. The specific morbidity rate was 2.7%. In a bivariate study, absence of mass and abdominal pain on palpation, hemoglobin level >11.55 g/dL, negative hydatid serology, cyst size, absence of calcifications, vascular compression, existence of a single cyst, and localization at segment VIII were predictive factors of occult CBF. At the end of the multivariate study, cyst size was determined to be the only predictive factor for occult CBF. A threshold of 3 cm was used. CONCLUSION: Cyst size is a major predictive factor for occult CBF.

Viability predictive factors of the daughter vesicles in hepatic cystic echinococcosis.

INTRODUCTION: Management of cystic echinococcosis (CE) requires knowledge of certain aspects related to the survival of Echinococcus granulosus. The viability of daughter vesicles (DV) is a determining factor in guiding therapeutic indications, particularly for transiently active Cysts type CE3b. PURPOSE: To determine the predictive factors of DV viability and its impact on the therapeutic management of CE3b type. MATERIALS AND METHODS: This is a prospective pilot study with an analytical aim on patients with cystic echinococcosis of the liver type CE2 and CE3b, operated in the General Surgery Department of Habib-Bourguiba Academic Hospital, Sfax-Tunisia for 22 months from March 2018 until December 2019. The unit of the study is the DV. A parasitological study of the DV was done in the parasitology laboratory. RESULTS: During the study period, 27 (40.9%) of 66 operated CE Disease from 21 patients containing 248 DV were explored. The median viability of DV protoscoleces was 16.7%. In bivariate analysis, factors for viability of DV protoscoleces were: fever, acute cholangitis, hyperbilirubinemia, left liver location, rock water and bilious echinococcal fluid (EF), cyst size ≥ 43 mm, Intracystic pressure ≥ 35 mmHg, DV size ≥ 6.5 mm, volume, number of DV/cyst ≥ 5, and opaque wall (p < 0.05). Predictive factors for the Non-viability of DV were: CE3b type, purulent EF, gelatinous EF. In multivariate analysis, only CE2 type, cyst size ≥ 43 mm, number of DV/cyst ≥ 5 and DV size ≥ 6.5 mm were factors significantly associated with the viability of DV protoscoleces. CONCLUSION: CE3b cysts without the criteria of viability of DV protoscoleces may become candidates for the 'Wait-and-Watch' procedure.

Localized stomach cancer: Perioperative or postoperative approach? A meta-analysis of phase III studies.

Background and Aim: Despite the development and standardization of surgical techniques in the treatment of localized gastric adenocarcinoma, the loco-regional and metastatic recurrence rate remains high. A combined radiochemotherapeutic regimen (the MacDonald regimen) as well as perioperative chemotherapy allows a significant improvement in the survival of patients with localized gastric adenocarcinoma with a reduction in the recurrence rate compared to surgery alone. The purpose of this review is to specify the best therapeutic approach in the treatment of localized gastric cancer. Methods: We performed a systemic search of Medline, Embase, and the Cochrane Central Register of Controlled Trials using PubMed, Google Scholar, and Ovid without language restriction. Hazard ratio (HR) with 95% confidence interval (CI) was reported. Results: We pooled 727 patients from two phase III randomized controlled trials. There was a benefit of perioperative chemotherapy versus surgery alone on the overall survival (OS) (HR = 0.72, 95% CI: 0.55-0.95) and on disease free survival (DFS) (HR = 0.65, CI: 0.50-0.85). Adjuvant chemotherapy was superior to surgery alone based on OS and disease free survival (CLASSIC study HR = 0.72, CI: 0.52-1 and HR = 0.56, CI: 0.44-0.72, respectively). Adjuvant radiochemotherapy was superior to surgery alone (HR = 1.35, 95% CI: 1.09-1.66; P = 0.005). Conclusion: A face-to-face comparison of perioperative chemotherapy versus adjuvant chemotherapy versus chemoradiotherapy is necessary.

Duplication cyst and diverticulum of the stomach: A case report of an unusual association.

Gastric duplication cysts are uncommon findings in adult patients. Accurate diagnosis of these cysts is difficult. Presenting symptoms are often non-specific, and complications are rare. We report an uncommon case of a non-communicating duplication cyst associated to a diverticula of the stomach in 38-year-old women.

Laser utility in the treatment of hemorrhoidal pathology: a review of literature.

Hemorrhoidal disease is a common reason for consultation in proctology. It can be treated in several ways (medical, endoscopic, and surgical). Laser treatment has been described since 1960 and has developed in recent years. The purpose of this literature review was to study the results of laser treatment of hemorrhoids and to compare them with those of surgical methods. We performed a systematic search of the literature by querying the Medline, Google Scholar, and Cochrane Library databases. Retrospective studies and case reports were excluded. We selected 11 studies both techniques HeLP (hemorrhoid laser procedure) and LHP (laser hemorrhoidoplasty procedure). The total number of patients was 1179 including 1059 patients treated with laser and 120 treated surgically within the context of comparative studies. The age of the patients varies between 18 and 74 years old. HeLP laser treatment was significantly superior to surgical treatment in terms of postoperative pain (p < 0.001), hemorrhoidal disease downgrading (p < 0.001), and postoperative satisfaction (p < 0.001). Similarly, LHP laser treatment was significantly superior to surgical treatment in terms of operative duration (p < 0.00001), intraoperative bleeding (p < 0.00001), postoperative pain at H12 and H24 (p < 0.00001 and p = 0.0003), and postoperative bleeding rate (p < 0.001). The laser represents a revolution in the field of proctology mainly in the treatment of hemorrhoidal pathology. It is a safe, effective, and less painful mini-invasive technique. More rigorous studies will be needed to better evaluate this technique.

Perforated jejunal diverticulitis with extensive diverticulosis: A case report.
