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.

Gastric trichobezoar: An uncommon cause of epigastric pain: A case report.

Trichobezoars are foreign and indigestible materials in the gastrointestinal tract and are usually found in psychiatric females, who often deny eating their own hair, but also at situations of gastric dysmotility and prior gastric surgery. Although rare, gastric trichobezoar should not be forgotten as a differential diagnosis in females presenting with vague epigastric pain. Its treatment well in time will prevent complications.

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.

Tailgut cyst: 2 case reports.

Tailgut cysts, or retrorectal cystic hamartomas, are rare congenital developmental lesions. It is a benign lesion, but there is a risk of degeneration, so surgical resection is necessary.

[Hemocholecyst complicated by rupture of the gallbladder]. / Hémocholécyste compliquée d'une rupture de la vésicule biliaire.

Hemocholecyst is defined as a hemorrhage into the gallbladder. It is a rare complication of anticoagulant therapies which can progress to spontaneous rupture of the gallbladder with hemorrhagic shock. We report the case of a 75-year old hypertensive, dyslipidemic man with hypertensive heart disease initially hospitalized for left hemiplegia. The patient received antiplatelet and anticoagulant therapy with low molecular weight heparin (LMWH) as prevention strategy. After 5 days of treatment the patient developed hemocholecyst and hemoperitoneum, confirmed by angio-abdominal computerized tomography scan in emergency assessment. The patient underwent cholecystectomy, hemostasis of the gallbladder fossa and evacuation of the hemoperitoneum.

Predictive factors of occult cystobiliary fistula after conservative surgical treatment of the hepatic hydatid cyst A retrospective study of 105 patients.

OBJECTIVES: The objective of our study was to determine the predictive factors of their occurrence during conservative surgical treatment of the hepatic hydatid cyst (HHC). PATIENTS AND METHODS: We carried out a retrospective review of patients who had undergone conservative surgical treatment of the HHC during 6 years. Univariate analyzes were used to determine the predictive factors of an occult cystobiliary fistula (CBF). RESULTS: This current study included 105 patients. Concerning the predictive factors of an CBF regardless of its pattern of evolution, we noted that the presence of fistula was statistically correlated with the a cyst size (bigger than 8.65 cm ; p = 0.003) and with advanced age (p=0.035). Interestingly enough, the correlation to a degenerated cyst (p=0.069) were of little significance. CONCLUSION: The size of the cyst greater than 8.65 cm and the advanced age are the risk factors of CBF according to our study. KEY WORDS: Biliary Fistula, Diagnosis, Echinococcosis, Hepatic, Prevention and control.

[Comparison between endoscopic stenting and colostomy in the management of obstructing cancer of the left colon: Literature review]. / Comparaison entre stent endoscopique et colostomie pour les cancers coliques gauches en occlusion : revue de la littérature.

INTRODUCTION: Colonic occlusion is the mode of discovery of 8 to 29% of colonic neoplasms. Our objective is to compare the placement of stent versus colostomy in the management of obstructing cancer of the left colon. MATERIAL AND METHODS: We have carried out a systematic search of literature from MEDLINE, EMBASE and Cochrane Library database to identify articles related to the comparison of stent versus colostomy published between 2000 and 2016. RESULTS: We have identified 6 studies. Only one study was prospective comparative. Three studies were for curative purposes. The total number of patients was 7205. In the "stent" group, there was a decrease in the average length of hospital stay compared to the "stoma" group and there was a decrease in cost with a statistically significant relationship. There was no difference between the two groups in terms of 4 hospital mortality and early morbidity. CONCLUSION: In case of neoplastic occlusion of the left colon, the choice between colostomy or colonic stent depends on the therapeutic strategy. Indeed, for curative strategy or administration of anti-angiogenics, it is recommended to practice a colostomy. However, for palliative treatment, colonic stenting is the treatment to follow.
