Amoeboma of the gallbladder mimicking a cholangiocarcinoma: A case report.

INTRODUCTION AND IMPORTANCE: Amoeboma is a pseudotumoral presentation of amebiasis which is a parasitic infection caused by entamoeba histolytica. Its location in the gallbladder is extremely rare. Indeed, only one other case was found in the literature. Therefore, we present this case report on managing a gallbladder amoeboma mimicking a cholangiocarcinoma. CASE PRESENTATION: A 62-year-old presenting for consultation for biliary colic that has been developing for 4 months without associated signs. MRI and thoraco-abdominal CT concluded to a cholangiocarcinoma of the gallbladder extended to the liver with probable localized peritoneal carcinosis. We, therefore, performed extended cholecystectomy with lymphadenectomy for the diagnosis of cholangiocarcinoma. Pathology concluded to an amoeboma of the gallbladder extended to the liver and duodenum. CLINICAL DISCUSSION: To our knowledge, there is only one case of gallbladder amoeboma in the literature making this case report valuable. It is important to draw lessons of this observation. Indeed, in front of the discrepancy between the clinic, biology (good general condition and negative tumor markers) and the imaging, we prefer this therapeutic strategy: make a biopsy of the hepatic parenchyma, realize amoebic serology to confirm the diagnosis. Then subject the patient to a therapeutic test based on metronidazole and confirm the disappearance of suspicious lesions by CT scan. CONCLUSION: Gallbladder amoeboma is an exceptional entity, but it needs to be kept in mind in case of an atypical presentation of a cholangiocarcinoma. Evoking and confirming the diagnosis preoperatively makes it possible to avoid excessive surgery.

Complications, treatment, and follow-up of peutz-jeghers syndrome: About 2 case reports.

INTRODUCTION: Peutz-Jeghers syndrome is an inherited disorder distinguished by hamartomatous polyps in the gastrointestinal tract and pigmented mucocutaneous lesions. Treatment of the polyps is never definitive, with most patients needing several laparotomies. For this reason, surgeons should be economical in terms of surgical resection to prevent a short bowel syndrome in the long run. In this paper, we report two observations of patients presented a Peutz Jeghers syndrome (PJS). CASES PRESENTATION: Case report 1: A 32-year-old women, who was operated on for an intestinal perforation related to a Peutz-jeghers hamartoma of the small bowel and was later re operated on for colonic intussusception, Case report 2: A 15-year-old patient that has been operated on three times already for small bowel intussusception and later for duodenal obstruction. CLINICAL DISCUSSION: In an attempt to reduce complications, the 2010 guidelines updated in 2021 by the European Hereditary Tumor group introduced obligatory monitoring by fibroscopy and colonoscopy associated with an entero-MRI or a videocapsule from the age of 8 years. Laparotomy is indicated when endoscopic treatment is impossible or in emergency setting. When surgery is indicated, intestinal resection should be reserved for rare cases in order to avoid short bowel syndrome. The association of an intraoperative endoscopic treatment is recommended by some authors. CONCLUSION: Peutz Jeghers syndrome is a rare entity with a complicated surveillance. Adequate polyp mapping is necessary for adequate planning of the treatment. The need for multiple laparotomies makes a comprehensive approach to surgery mandatory to prevent short bowel syndrome.

Surgical management of a benign multicystic peritoneal mesothelioma: A case report.

INTRODUCTION AND IMPORTANCE: Benign multicystic peritoneal mesothelioma is rare, with around 200 cases reported in the literature. We report the case of a patient operated on for the diagnosis of cystic lymphangioma but the pathology examination retained the diagnosis of benign cystic peritoneal mesothelioma. CASE PRESENTATION: A 47-year-old patient, who consulted for abdominal distension evolving for a year. Examination revealed a 30-centimeter abdominal mass. The CT scan showed an intraperitoneal cystic mass measuring 24 × 13 × 32 cm. The diagnosis of cystic lymphangioma was suspected and we decided to surgically remove the mass. We performed a laparotomy. There was a large multi-cystic formation that seemed to develop at the expense of the parietal peritoneum and the greater omentum. A monobloc resection was performed. The postoperative was eventless. Pathology concluded to a benign cystic peritoneal mesothelioma. DISCUSSION: The BMPM is a rare peritoneal neoplasm that develops mainly in women, during sexual activity. Its etiopathogenesis is unknown. It is often mesenteric or omental. Generally, resection is considered the sole treatment for benign mesotheliomas. However, this surgery needs to be R0 or it will expose to a certain recurrence. Some authors recommend a more aggressive approach associating cytoreductive surgery with heated intraperitoneal chemotherapy. CONCLUSION: Benign multicystic peritoneal mesothelioma is a rare pathology of the peritoneum which develops mainly in women during periods of reproductive activity. Despite its benignity, it presents a high risk of recurrence, up to 50 % of cases.

Caecal volvulus in an adult with an incomplete common mesentery: A case report.

INTRODUCTION AND IMPORTANCE: A common mesentery is defined by the persistence of an embryonic anatomical arrangement secondary to an anomaly of rotation of the primary umbilical loop. Caecal volvulus is a rare cause of intestinal obstruction, which account for 1 to 1.5 % of all intestinal obstructions. A combination of both, intestinal mal rotation and caecal volvulus is rare. CASE PRESENTATION: We report this rare entity in a 50 year old male with no history of abdominal surgery who was admitted for an acute intestinal obstruction. Clinical examination found a non-complicated right inguinal hernia. Radiological assessment showed signs of an incomplete common mesentery and an important small bowl distention with a transitional zone near the profound inguinal ring. Emergency surgery was performed. Surgical exploration didn't find signs of strangulation in the inguinal hernia which motivated midline laparotomy. We discovered a caecal volvulus with an incomplete common mesentery and ischemic lesions in the caecum. Ileocaecal resection was performed with ileocolostomy. DISCUSSION: Common mesentery can be complete or incomplete. It is often well tolerated in adulthood. This intestinal malrotation can sometimes cause serious complications such as volvulus. Their association is rare. Radiology can be very helpful in leading to the diagnosis, but the diagnostic process should not delay surgical intervention which is the basis of the treatment. CONCLUSION: Caecal volvulus is a serious complication of intestinal malrotation. This association is rare in adulthood and symptoms are not specific. Emergency surgery is necessary.

Inferior vena cava resection for a leiomyosarcoma: A case report.

INTRODUCTION AND IMPORTANCE: Leiomyosarcomas of the inferior vena cava are scarce. Surgery is the only potential curative treatment. Such a surgery is complex and technically demanding, requiring a huge experience in both visceral and vascular surgery. Indeed, enlarged visceral resection may be needed to achieve a free tumor margins as the tumor may invade the duodenum, the head of the pancreas and the liver. Moreover, vascular reconstruction is mandatory which might be complex as both venal reins are usually invaded by the tumor like in our case below. CASE PRESENTATION: A 53-year-old woman presented with abdominal vague pain. Imaging consisting in abdominal CT-scan with contrast and magnetic resonance angiography were suggestive of the diagnosis of leiomyosarcoma of the inferior vena cava. A surgical complete resection with free margins was conducted. A primary repair of the inferior vena cava and the right renal vein walls. End-to-side anastomosis with a polytetrafluorethylene (PTFE) prosthesis was mandatory to reconstruct the renal left vein to the inferior vena cava. Postoperative outcomes were uneventful. Pathology examination confirmed the diagnosis. DISCUSSION: The optimal management of leiomyosarcoma of inferior vena cava is controversial. Surgery remains the cornerstone of treatment. However, not all patients are qualified for surgical resection. The prognosis depends on the early diagnosis and histology type. CONCLUSION: The management of leiomyosarcomas of inferior vena cava requires a multidisciplinary consensus involving experienced surgery and oncology teams.

An uncommon way of revelation of a primary diaphragmatic hydatid cyst: A case report.

INTRODUCTION AND IMPORTANCE: Diaphragmatic hydatid cyst is a misdiagnosed condition. The challenge is to suspect this rare entity on nonspecific clinical features and to localize the cyst on imaging in order to determine the surgical approach. Surgery is the only curative treatment and confirmation is set on pathology examination. CASE PRESENTATION: We present the case of a twenty-six-year-old patient, with no medical history, who complained of recurrent right thoracic pains rebel to opioids. All radiological items lead to suspect a diaphragmatic hydatid cyst. Surgery permitted a complete resection of the cyst and a total relief of the pains. CLINICAL DISCUSSION: The diagnosis of diaphragmatic hydatid cyst is a real challenge. Several diagnoses can be evoked such as hydatid disease depending from the liver, cystic lymphangioma or neural intercostal benign tumor. The phrenic origin of the cyst can only be identified through surgery. However, it is very important to clearly characterize the lesion to well conduct surgical approach. CONCLUSION: It is important for surgeons to suspect diaphragmatic hydatid cysts despite its rarity. CT-scan and MRI are helpful tools to localize the disease and to conduct the surgical procedure. Final diagnosis is only set on pathology examination after curative surgery.

Surgical treatment of a presacral schwannoma: A case report.

Introduction and importance: Schwannomas are rare benign tumors that develop from Schwann cells that represent 0.3 to 0.4 cases per 100,000 persons per year. We report a case of pre-sacral schwannoma, a rare tumor, especially in the pelvic area. This case comes to help further teams in their management as its scarcity made any attempt to make proper recommendations obsolete. Case presentation: a 53-year-old otherwise healthy woman who presented with a 2-year history of right-sided sciatica. The radiologic characteristics of the mass suggested presacral schwannoma type III of the Klimo classification as the most possible diagnosis.Therefore, surgical resection was decided, and an anterior approach was chosen. By laparotomy a 6cm retroperitoneal encapsulated mass with no invasion of the adjacent organs. We performed a digital enucleation of the tumor through a capsulotomy.Pathology confirmed the diagnosis of schwannoma. There were no features of malignancy. The post-operative period was uneventful. A follow-up examination at 6 months showed no signs of numbness or weakness in the right leg. The previously described pain totally regressed. Discussion: Although schwannoma is a benign lesion, it may become malignant, especially when associated with neurofibromatosis making its surgical removal primordial. Its pelvic location may make its diagnosis delayed due to non-specific symptoms mainly through compression of local organs. Its surgical management can be challenging due to large size tumors with adherence to peritoneal and retroperitoneal organs. Quality of the resection is important in the recurrence and necessity for reoperation. A multidisciplinary approach is therefore recommended to ensure optimal treatment. Conclusion: Due to its rareness, there is no clear consensus in on the management of schwannomas therefore we chose to write our case in order to further enrich the literature to achieve one-day guidelines for schwannoma treatment.

Spontaneous rupture of a left omental artery aneurysm treated by transcatheter arterial embolization: A case report.

Background: Omental artery aneurysms are extremely rare. Their rupture is related to high mortality and often treated by open surgery. We describe a case of a spontaneous rupture of a left omental artery aneurysm (OAA) that was successfully treated by transcatheter arterial embolization (TAE). Case presentation: A 68-year-old man presented with acute abdominal pain. On examination, he was hypotensive and tachycardic with a blood pressure of 90/50 mm Hg. He had diffuse abdominal distension and tenderness.An abdominal enhanced computed tomography scan (CT) showed a rupture of the left OAA responsible for moderate hemoperitoneum. We performed a successful TAE. Conclusion: Ruptured OAA causes high mortality. OAA represents the rarest form of splanchnic artery aneurysms. Interventional radiology permits to avoid unnecessary surgery.TAE is a safe procedure to control ruptured OAA. We highlight the importance of a rapid embolization if the patient is hemodynamically stable.

Intra-abdominal cystic lymphangioma in adults: A case series of 32 patients and literature review.

Introduction: Cystic lymphangioma (CL) is a benign tumor originating from the lymph vessels. Lymphangiomas in the abdominal cavity are extremely rare, particularly in adults.This article was designed to study the epidemiological, diagnostic difficulties, and therapeutic principles of intra-abdominal cystic lymphangioma (ACL) in adults. Material and methods: We conducted a single-center, retrospective study of 32 adult patients with ACL admitted to surgical department "A" in "La Rabta Hospital" in Tunis, from January 1998 through December 2020. The demographic, clinical, biological, radiological characteristics, histopathologic, and therapeutic data were collected, as well as the surgical intervention used and the postoperative immediate and late complications. Results: Thirty-two adult patients with ACL were recruited, including 20 females and 12 males. The median age at treatment was 47 (range 14-80) years. The most prevalent sites were the retroperitoneum (25%), the mesentery (21.9%), and the paracolic gutters (n = 18. 7%). Twenty patients underwent open surgery (62.5%), whereas 12 cases (37.5%) had laparoscopic surgery. Twenty-eight patients received total cystectomy (87%). Three recurrences were observed during follow-up (9.4%). Conclusion: The clinical features of CL in adults remain unclear. The diagnosis is only confirmed by histopathological examination after complete surgical resection. The laparoscopic approach is considered safe and feasible.

Acute cholangitis due to haemobilia complicating percutaneous cholecystostomy: First literature case report.

BACKGROUND: Laparoscopic cholecystectomy is the standard treatment for acute cholecystitis. Cholecystostomy is a good option in patients with significant comorbidities. We report a case of a patient having had a percutaneous cholecystostomy for acute cholecystitis complicated with haemobilia and acute cholangitis. PRESENTATION OF A CASE: A woman aged 64 years old, with a history of diabetes, arterial hypertension, and chronic obstructive pulmonary disease was admitted to our institution with acute cholecystitis. We opted for transhepatic percutaneous cholecystostomy (PC) and antibiotics. On the fourth day, the patient had acute cholangitis due to haemobilia. We injected physiologic saline serum through the drain of cholecystostomy to dissolve the blood clot. There was a clinical improvement. We performed laparoscopic cholecystectomy two months later. The patient had an uneventful recovery with a follow-up of five months. DISCUSSION: We report the first literature report of acute cholangitis due to haemobilia complicating percutaneous cholecystostomy in a patient admitted for cholecystitis. We highlight the importance of the injection of saline physiologic serum from the catheter. Medical treatment with antibiotics may be enough knowing that blood clots can disappear spontaneously. In case of failure, ERCP with sphincterotomy should be performed. CONCLUSION: Haemobilia causing acute cholangitis is a rare complication of percutaneous cholecystostomy. Conservative treatment with antibiotics and injection of saline physiologic serum from the catheter is a good treatment option. In case of failure, ERCP should not be delayed.

Case report of a recurrent resected glucagonoma.

Introduction and importance: Glucagonoma is a rare neuroendocrine tumor (NET). Most glucagonomas are in the tail or body of the pancreas and are diagnosed at a metastatic stage. We report a case of an early recurrence after surgical resection of a glucagonoma and its management. Case report: We present a case of a 44-year-old female patient with no medical and surgical history, operated on in May 2018 for pancreatic glucagonoma revealed by skin necrolytic migratory erythema. The patient was regularly monitored by clinical exams and CT scans. In December 2020 (31 months postoperatively), we noticed the recurrence of the cutaneous lesions.Admission laboratory measurements demonstrated hyperglycemia as well as elevated blood Glucagon levels. Explorations showed 3 retro-pancreatic lesions. Based on these findings, we concluded that it was a recurrence of her glucagonoma. The patient was operated on by median laparotomy We performed a warshow's procedure.Pathology confirmed the endocrine nature of the 3 nodules. We are currently 6 months behind the surgery. The examination is strictly normal with no recurrence of the skin lesions so far. Clinical discussion: Surgical resection on a recurrent glucagonoma is what is unique in our case as we haven't found any case in the literature to our knowledge.What is also unique about our case is both the local aspect of the recurrence and the multiplicity of the tumors observed as multiple nodules around the tail of the pancreas. These lesions were not metastatic lymph nodes as confirmed by pathology. Probably it was an effraction of the big tumor at enucleation. Conclusion: Due to its rareness, there is no clear consensus on the management of glucagonomas therefore we chose to write our case in order to further enrich the literature to achieve one-day guidelines for glucagonomas treatment.

Risk stratifying patients with non-varicosic upper gastrointestinal hemorrhage using the Glasgow-Blatchford score: A case series of 91 patients.

Introduction: Non-variceal upper gastrointestinal hemorrhage (NVUGIH) often leads to systematic hospitalization and emergency endoscopy. However, in most cases, it does not constitute an immediate life threat. This study aimed to evaluate the Glasgow-Blatchford Score (GBS) in predicting the need for transfusions, and/or endoscopic or surgical treatments. Materials and methods: We conducted a retrospective monocentric study including 91 patients admitted in the general surgery department of the Hospital La Rabta Tunis for a NVUGIH.Univariate analysis was performed with the Student t-test for continuous variables and with the Chi-square test for categorical variables. For a cut-off point of 9, we calculated the sensibility and the sensitivity of the GBS to predict the need for transfusions and/or hemostatic procedure. Results: During the study period, 91 patients were admitted for NVUGIH. Sixty-one patients (67%) were transfused. Seven patients (7.7%) underwent emergency surgery and two patients had endoscopic hemostasis.The predictive factors for the use of transfusion and/or hemostasic treatments were: Age >50 years, ASA score, HR ≥ 90 bpm, pallor, Hb ≤ 9,5 g/dl, Urea ≥9,7 mmol/L.For a cut-off of 9 points of the GBS, sensitivity was 85.71% and specificity 92.86%. The positive predictive value was 96%. The negative predictive value was 74%. Conclusion: The main interest of the GBS lies in dispatching the patients between intensive care units for therapeutic intervention (if GBS> = 9) and ordinary hospitalization for surveillance (if GBS <9). It then makes it possible to rationalize the management of patients with digestive hemorrhage to identify those requiring hospital treatments (transfusion, endoscopic treatment, or surgery).

A rare association of caecal volvulus and intestinal malrotation causing an acute abdomen: Case report.

INTRODUCTION: and importance: Caecal volvulus represents 30% of colonic volvulus. It happens due to torsion or hyperflexion of a hypermobile caecum. Usually it is secondary to an axial rotation of the caecum and the ileum around the mesentery. On the other hand Intestinal malrotation occurs due to incomplete or faulty rotation and fixation of the gut during fetal life. The occurrence of these two anomalies together is scarse which makes this case report interesting. CASE PRESENTATION: A 75 year old man with medical history of terminal kidney failure, presented to the emergency room with an intestinal obstruction syndrome. On examination the patient had a distended abdomen with tenderness in the left upper quadrant. Biology found an important biological inflammatory syndrome with hyperleukocytosis and elevated CRP. Plain X-ray of the abdomen in erect posture showed an air fluid colonic level in the left hypochondrium. CT scan showed signs of caecal volvulus with intestinal malrotation. A brief reanimation and nasogastric aspiration couldn't solve the problem therefore emergency laparotomy was needed ileocaecal resection was performed associated with LADD's procedure in order to treat both anomalies and prevent further gut volvulus. CLINICAL DISCUSSION: Despite it's rareness, caecul volvulus represents the second cause of large bowel volvulus just behind sigmoid volvulus. Intestinal malrotation in adults subjects is estimated to occur in 0.2-0.5%.The uniqueness of our case is that these two anomalies were associated in such a way that it made both the diagnosis and the therapy even more difficult. Abdominal CT has become mandatory for pre-operative diagnosis of intestinal volvulus. Surgery is the gold standard treatment for caecal volvulus. The usual options are manual detorsion, carcopexy, caecostomy and colectomy. CONCLUSION: This case reports a rare association of a caecum volvulus with intestinal malrotation that emphasis the place of modern technologies such as CT scan in order to achieve correct preoperative diagnosis. We also describe our approach to this uncommon surgical emergency in order to provide an efficient treatement.

Primary duodenal tuberculosis complicated with perforation: A review of literature and case report.

Tuberculous (TB) disease remains an endemic pathology in Tunisia. the ileocecal region is the predominant site of involvement while gastroduodenal tuberculosis is very rare, this form is often presenting as one of the complications, mainly upper gastrointestinal stenosis or exceptionally as a perforation. We describe a case of female patient aged 33 years-old presented with a 2-day history of acute abdominal pain, with a tenderness of the right hypochondrium and the epigastrium, ultrasound of the abdomen revealed gallbladder distension with a wall thickening. The diagnosis of acute cholecystitis was suspected and the patient had an exploratory laparoscopy that revealed the presence of a perforated duodenal ulcer which was blocked by the gallbladder and several peri-duodenal lymph nodes. Cholecystectomy was performed and the edges of the ulcer were resected and the ulcer was sutured. Histological examination revealed duodenal tuberculosis and the patient was referred to the TB eradication program.

The management of hidradenitis suppurativa degenerating into squamous cell carcinoma: About three case reports.

INTRODUCTION AND IMPORTANCE: Hidradenitis suppurativa (HS) is a chronic inflammatory and suppurative disease of the apocrine sweat glands. Its transformation into squamous cell carcinoma (SCC) is very rare. CASE PRESENTATION: We describe 3 cases of males aged 57, 58 and 55-years-old. The diagnoses were confirmed by pathology examination in all cases. Two of our patients underwent extended and complete surgery. The first two patients died during the year after the diagnosis was established, the third one is still alive with no recurrence after one year of surgery. CLINICAL DISCUSSION: Hidradenitis suppurativa mostly concerns perianal location and it targets mainly male patients with a multifactorial development. Surgical treatment consists of large excision. The SCC is associated with a high mortality rate. CONCLUSION: Hidradenitis suppurativa needs early diagnosis and effective surgery. The transformation into squamous cell carcinoma is rare and and its management is challenging. Extended and complete excision is required with rigorous postoperative follow-up.

Acute pancreatitis as an uncommon complication of hydatid cyst of the liver: A case report and systematic literature review.

Hydatid disease is a major health problem worldwide. The liver is the most frequent location of hydatid disease. Acute pancreatitis secondary to liver hydatid cyst ruptured in the biliary tract is scarce and fewly described in literature. The management of this pancreatic complication of liver hydatid disease is challenging and includes a combination of surgical and endoscopic approaches. We report herein a rare case of hydatid cyst of the liver with cysto-biliary communication revealed by acute pancreatitis. A systematic literature review of similar cases reported was provided to compare surgical and endoscopic techniques. A thirty-year-old woman was referred to our emergency unit for acute pancreatitis. The CT-scan findings revealed a liver hydatid cyst ruptured in the biliary tract and daughter vesicles within were found, responsible for C-grade acute pancreatitis. We decided then to perform an emergency surgery through a bisoucostal incision. We performed a cholecystectomy and a peroperative cholangiogram that showed the communication between the cyst and left biliary tracts and the presence of daughter vesicle within the common bile duct. We conducted an exploration of the common bile duct with extraction of vesicle daughters. We left behind a T-tube in the common bile duct and we sutured the cysto-biliary fistula. Drainage was left in the remnant cavity after unroofing the cyst. Postoperative course was uneventful. Six months follow-up showed no recurrence. Cysto-biliary communication of liver hydatid disease revealed by acute pancreatitis is uncommon. We chose to perform emergency open surgery. However, through a systematic literature review, we noticed that endoscopic treatment is an efficient therapeutic and diagnostic tool to delay a morbid surgery of the liver and the common bile duct.
