Postoperative morbidity risk factors after conservative surgery of hydatic cyst of the liver: a retrospective study of 151 hydatic cysts of the liver.

BACKGROUND: The purpose of the present paper is to assess the morbidity specifics risk factors of hepatic hydatid cyst after conservative surgery. METHODS: We conducted a retrospective study of 102 patients over a period of 13 years, from 2006 to 2019. We included all patients operated on hydatid cyst of the liver, complicated and uncomplicated, in the Department of General Surgery in Tahar Sfar hospital, Mahdia, Tunisia. We excluded patients who received an exclusive medical treatment and those who have other hydatic cyst localizations. RESULTS: The cohort was composed of 102 patients with a total of 151 cysts operated on using conservative surgery, among them there was 75 women (73.5%) and 27 men (26.5%). The median age was 43, with extremes ranging from 12 to 88 years. The majority of patients (94.1%) were from rural areas. The cysts were uncomplicated in about half of the cases (48%), elsewhere complications such as compression of neighboring organs (25.5%), opening in the bile ducts (16.7%), infection (9.8%), and rupture in the peritoneum (2%) were found. Conservative surgery was the mainstay of treatment with an overall mortality rate of 1.9%. The overall morbidity rate was 22%: 14% specific morbidity and 8% non-specific morbidity. External biliary fistula was the most common postoperative complication (9%). The predictive factors of morbidity in univariate analysis were: preoperative hydatid cyst infection (P = 0.01), Compressive cysts (P = 0.05), preoperative fever and jaundice, (respectively P = 0.03 and P = 0.02), no one achieved statistical significance in the multivariate model. CONCLUSIONS: Preoperative hydatid cyst infection, compressive cysts and preoperative fever and jaundice could be predictor factors of morbidity after conservative surgery for liver hydatid cyst. They must be considered in the treatment and the surgical decision for patients with hydatid cyst.

Retrorectal epidermoid mistaken for perirectal swelling: A case report.

INTRODUCTION AND IMPORTANCE: Epidermoid cysts are developmental cysts of the retrorectal space. They are benign lesions resulting from ectodermal inclusion during neural tube closure. Generally, they are misdiagnosed given that symptoms are often vague and nonspecific. They have a high infection rate (up to 30%) and can be easily mistaken for perirectal abscesses. CASE PRESENTATION: We present a case of an epidermoid cyst in a 58-year-old woman with a retrorectal cyst mistaken for a perianal abscess, which was initially incised and drained and then, after MRI investigation, an anterior resection was performed. CLINICAL DISCUSSION: Epidermoid cysts have a high infection rate (up to 30%). Infected cysts can be easily mistaken for perirectal abscesses, pilonidal disease, or fistulae in ano. CT (computed tomography) used in conjunction with MRI (Magnetic Resonance Imaging) is the gold standard for establishing the diagnosis. A biopsy is never indicated. Surgery is the best treatment, even for asymptomatic lesions. CONCLUSION: Epidermoid cysts are rare and generally misdiagnosed. In fact, symptoms are often vague and nonspecific. Radiologic imaging (especially MRI) is essential for surgical planning and biopsy should be avoided. Once a presacral lesion is diagnosed, even if the patient is asymptomatic, complete resection remains the treatment of choice because of the risk of infection.

Clear cell carcinoma of the abdominal wall: A case report with a review of the literature.

Introduction and importance: Clear cell carcinoma of abdominal wall is a very rare and aggressive disease. It is mostly related to malignant transformation of abdominal wall endometriosis. This paper provides a new case report and a literature review of primitive abdominal wall clear cell carcinoma. Case presentation: A 45-year-old woman with a history of a two previous caesarian section presented to the outpatient department with a tumor mass evolving since 10 years in the lower right quadrant of her abdomen. Imaging studies revealed a voluminous subcutaneous mass developing at the expense of the anterior abdominal wall. Surgical resection of the mass was performed. Histopathological examination along with immunohistochemical analysis were consistent with clear cell carcinoma. Biopsies of the endometrium and ovaries were performed and were negative for malignancy. The patient underwent therefore a hysterectomy with bilateral salpingo-oophorectomy which did not reveal any disease. The diagnosis of primitive clear cell carcinoma of the abdominal wall was then confirmed. Clinical discussion: Primitive clear cell carcinoma of the abdominal wall is an extremely rare form of cancer with usually poor prognosis. Clinicians must be aware of the possibility of malignancy of any swelling mass occurring near or within a caesarean section scar. Conclusion: Reporting more such cases is still needed to further progress in the understanding of this malignancy in addition to the development of treatment strategies.

Acute abdomen during pregnancy: appendicular deciduosis-a case report.

Despite the fact that it is rarely found in the appendix during pregnancy, ectopic decidua can, in some cases, cause the occlusion of the appendicular lumen by extrinsic compression due to the expansion of endometrial tissue or due to decidua polyp formation. This condition consequently leads to appendicular inflammation. We report the case of a 27-year-old primigravida woman, 32 weeks of gestation, who presented to our facility with a 2-day history of isolated right iliac fossa pain. The diagnosis of an acute appendicitis was suspected and a planned appendectomy was performed. Microscopical examination showed appendicular deciduosis.
