A rare differential diagnosis of aortic stenosis with a black aortic valve: A case report

BackgroundCardiac ochronosis, presenting as a rare manifestation of alkaptonuria, an autosomal recessive disorder, is characterised by black pigmentation of calcified cardiac valves and atherosclerotic plaques. We report an intraoperative dilemma on the discovery on the black aortic valve in a case of an old lady with degenerative calcific aortic stenosis.Case presentationA 60-year-old lady was electively admitted for valve replacement with a bioprosthetic valve for severe aortic stenosis. She was symptomatic with complaints of headache and giddiness and had a pressure gradient of 113/17mmhg across the aortic valve. Intraoperatively, she was found to have cardiac ochronosis on the discovery of pigmented aortic intima extending to the valve leaflets and underwent valve replacement with a mechanical prosthetic valve. She was post-operatively evaluated for the same and diagnosed with alkaptonuria. Though the surgery went uneventful and the patient was discharged without any complication, she was advised to be on regular follow-up to assess valve gradients, paravalvular leaks and to monitor the disease progression.ConclusionThe presented case sheds light on the rare cardiac manifestation of alkaptonuria. In the absence of definitive pre-operative diagnosis, intraoperative findings played a pivotal role in guiding the surgical approach and choice of prosthetic valve. The decision to use a mechanical valve was influenced by the potential risks associated with bioprosthetic valves in the setting of ochronosis. Ongoing follow-up and monitoring are essential to assess the durability of the chosen prosthetic valve and to manage any long-term consequences of the underlying metabolic condition.

Primary neuroendocrine tumor of the perihilar bile duct: A case report

Neuroendocrine tumors (NETs) arising from extrahepatic bile ducts are very rare. We present a patient with perihilar NET who was operated on with a preoperative diagnosis of Klatskin tumor. A 58-year-old female patient was admitted with abdominal pain and jaundice. Laboratory data showed elevated serum bilirubin levels and liver function tests. Computed tomography (CT) and magnetic resonance cholangiopancreatography (MRCP) findings were consistent with perihilar bile duct tumor. The patient was operated on with a diagnosis of Klatskin tumor. She underwent right hepatectomy, resection of the extrahepatic bile duct, portal lymphadenectomy and Roux-en-Y hepaticojejunostomy. The final pathologic examination of the resected specimen demonstrated a well differentiated neuroendocrine tumor (Grade 1). NETs originating from perihilar bile ducts are extremely rare, and preoperative definite diagnosis is very difficult. It should be kept in mind that NET may be one of the rare causes of perihilar bile duct obstruction.

Adrenal pseudo cyst presenting as retroperitoneal lesion: a rare presentation

Adrenal pseudocyst are cystic lesions arising from the adrenal gland and do not contain any definitive epithelial lining. These are extremely rare and very few cases are reported, representing 1-2% of adrenal incidentalomas. Patients generally have a non-specific presentation with most patients being asymptomatic and detected incidentally, while others may present with the ensuing mass symptoms in cases of large cysts. Multiple differential diagnosis may be considered for the same. Here we reported the case of a 43 year old female who presented to us with worsening pain abdomen in the left upper quadrant. An ultrasonography revealed an 8×9×9 cm cystic lesion in the region of the tail of pancreas. Subsequent CT was suggestive of a retroperitoneal cyst with multiple diagnostic possibilities owing to the many intra-abdominal structures it was found to be associated with. A definitive pre-operative diagnosis regarding the origin of the cystic swelling could not be made. A decision to remove the lesion operatively via an open approach through an upper midline laparotomy was made and eventual histopathological diagnosis confirmed it to be an adrenal pseudocyst.

THE DIAGNOSTIC ACCURACY OF INTRAOPERATIVE SYNOVIAL FLUID CALPROTECTIN IN SUSPECTED LOW-GRADE PERIPROSTHETIC HIP JOINT INFECTIONS

Pre-operative definitive diagnosis of infection in painful total hip arthroplasty (THA) is not always easy to be established, making the intra-operative decision-making process crucial in management of revision hip surgery. Calprotectin is a promising point-of-care novel biomarker that has displayed high accuracy in detecting PJIs.From November 2020 to December 2022, 105 patients with painful primary THA were treated with revision THA in 3 orthopaedic departments. Pre-operatively, 23 were considered infected and treated with two-stage revision THA. The remaining 82 were likely infected according to the 2019 EBJIS criteria. The suspicion of low-grade infection was based on clinical (rest and/or night pain), laboratory (CRP, ESR, WBC – normal or slightly elevated) and radiological evaluation (loosening). Hip aspiration under CT imaging was performed in these cases and 34 of them yielded positive culture and were treated with two-stage revision. Aspiration was ineffective in the remaining 48 cases (33 negative, 15 unsuccessful attempts). Intra-operatively, calprotectin was measured with lateral flow immunoassay test in these patients. Cases with calprotectin levels ≥ 50 mg/L were treated with 2-stage revision THA; otherwise, they were considered not-infected and one-stage revision was performed. Synovial fluid and tissue samples were collected for analysis. Implants were sent for sonication fluid cultures.Calprotectin was positive (≥ 50 mg/L) in 27 cases and negative in 21 cases. There was 1 false negative case with positive tissue cultures. Out of the 27 positive cases, 25 had positive tissue cultures and sonication. However, 2 cases with high calprotectin levels (>200 mg/L) were not infected. The false positive result was attributed to severe metallosis. Calprotectin sensitivity was 96.2%, specificity 90.9%, PPV 92.6%, NPV 95.2%, AUC 0.935.The results of this ongoing study indicate that calprotectin seems to be a valuable tool in facilitating the intra-operative decision-making process in cases that low-grade infection is suspected and diagnosis cannot be established pre-operatively.

Mixed neuroendocrine–non-neuroendocrine neoplasm of the ampulla of Vater: a case report

BackgroundMixed neuroendocrine–non-neuroendocrine neoplasms of the ampulla of Vater are rare and heterogenous, making it difficult to achieve a definitive preoperative diagnosis. Herein, we describe a patient in whom a provisional diagnosis of mixed neuroendocrine–non-neuroendocrine neoplasm of the ampulla of Vater was made preoperatively.Case presentationComputed tomography revealed an enhancing periampullary tumor in a 69-year-old man with obstructive jaundice. Subsequent duodenoscopy revealed an ulcerated lesion in the swollen ampulla of Vater, from which six biopsies were collected. Pathological examination revealed adenocarcinoma in five of them. The remaining one was a neuroendocrine neoplasm according to immunohistochemical analysis. With a provisional diagnosis of mixed neuroendocrine–non-neuroendocrine neoplasm of the ampulla of Vater, the patient underwent subtotal stomach-preserving pancreaticoduodenectomy with modified Child’s reconstruction and was discharged without complications. Pathological examination revealed both adenocarcinoma and neuroendocrine carcinomas, each accounting for ≥ 30% of the tumor, resulting in a definitive diagnosis of mixed neuroendocrine–non-neuroendocrine neoplasm of the ampulla of Vater. Lymph node metastases with neuroendocrine components were also observed. Adjuvant chemotherapy was not administered because of the patient’s renal dysfunction. Liver and lymph node metastases were detected 2 months after surgery, the neuroendocrine component being considered responsible for that relapse. The patient underwent platinum-based chemotherapy at 50% dosage, which initially resulted in significant tumor shrinkage; however, he died 6 months after surgery.ConclusionsWhile these tumors’ heterogeneity make definitive preoperative diagnosis of mixed neuroendocrine–non-neuroendocrine neoplasm of the ampulla of Vater difficult, the possibility of this disease can be considered by careful examination. Further study is needed to establish the optimal diagnostic criteria and treatment strategy.

IDIOPATHIC ABDOMINAL COCOON - A RARE CAUSE OF SMALL BOWEL OBSTRUCTION

The idiopathic form of sclerosing encapsulating peritonitis, also known as abdominal cocoon, is a rare entity of unknown cause that leads to intestinal obstruction due to complete or partial encapsulation of the small intestine by a fibrocollagenous membrane. As the initial clinical features are non-specific, they often remain unrecognized making it difficult to make a definite pre-operative diagnosis. Recurrent episodes of small intestinal obstruction along with relevant imaging findings and lack of other causative mechanisms, gives rise to a clinical suspicion. We report a young lady who presented to us with features suggestive of acute intestinal obstruction. Thorough enquiry revealed similar episodes on multiple occasions in the past which was temporarily relieved with conservative management. The need to keep an open mind regarding the uncommon causes of commonly encountered problems is the point of interest in our case.

Evaluation of different treatment modalities for diffuse uterine leiomyomatosis: A case series report and review of the literature.

To provide perspectives on preoperative diagnosis and conservative treatment for diffuse uterine leiomyomatosis (DUL). The clinical characteristics, management, and outcome of the five cases diagnosed with DUL receiving surgical treatment at Peking Union Medical College Hospital between January 2010 and December 2021 were retrospectively analyzed. DUL is a diagnosis based on histopathology. It is a subtype of uterine leiomyoma, characterized by innumerable, poorly circumscribed hypercellular nodules of bland smooth muscle cells with no cytologic atypia diffusely involving the myometrium. Clinical manifestations, including menorrhagia, anemia, and infertility, are similar to those of typical uterine leiomyomas, making a definitive preoperative diagnosis difficult. Magnetic resonance imaging plays an important role in the pre-treatment mapping. Conservative surgery can reduce the uterine volume and improve the contour of the uterine cavity, thereby relieving symptoms of menorrhagia and improving the chance of conception. Gonadotropin-releasing hormone (GnRH) agonist therapy is of great significance for controlling vaginal bleeding, reducing uterine volume, and delaying postoperative recurrence, and can be used alone or as postoperative adjuvant therapy for conservative surgery. The treatment goal for DUL patients with fertility-sparing request should not aim at complete fibroid removal. A successful pregnancy can be achieved following conservative surgery and/or GnRH agonist therapy.

Gastrointestinal: Small bowel hemangioma with unusual endoscopic findings and complicated with obscure gastrointestinal bleeding.

A 68-year-old woman was referred to our hospital for evaluation of severe anemia. Although she had an upper endoscopy and colonoscopy that failed to show the cause of her anemia, there was a small amount of blood in the terminal ileum, which suggested small bowel bleeding. In our hospital, video capsule endoscopy identified a spherically raised lesion in the jejunum, with central erosion of the surface mucosa, which was similar in morphology to a submucosal tumor (Fig. 1a). Balloon-assisted enteroscopy revealed a dark reddish, elevated lesion in the jejunum, the surface of which was extensively peeled off and thickly covered by blood clots (Fig. 1b). Malignant tumors such as angiosarcoma, gastrointestinal stromal tumor, and malignant lymphoma were suspected. A definitive preoperative diagnosis was difficult because of the unusual endoscopic findings. The patient underwent laparoscopic small bowel resection. The lesion was 17 mm in diameter (Fig. 2a). Histological findings revealed that the elevated lesion consisted of exposed vascular components, surrounded by normal small bowel mucosa, and numerous dilatated vessels without atypia were observed from the lamina propria to the muscularis propria. These findings were consistent with cavernous hemangioma (Fig. 2b,c). After surgery, the anemia improved within 6 months. Hemangiomas occur rarely in the small bowel. Thirteen cases of small bowel hemangiomas, observed preoperatively by enteroscopy, have been reported in adults. To the best of our knowledge, a submucosal tumor-like hemangioma with exposed vascular components is extremely rare and has been described in only one case. It was hypothesized that this uncommon morphology was formed by collapse of the tumor due to external stimuli such as small bowel peristalsis and food residue. This case highlights the unusual endoscopic appearance of small bowel hemangioma as a rare cause of obscure gastrointestinal bleeding.

Epidermal Cyst in an Intrapancreatic Accessory Spleen.

A 59-year-old asymptomatic woman with no disease history presented to our institution for investigation of a pancreatic tail mass. Hematological parameters were within normal ranges, including serum carcinoembryonic antigen levels and carboxyhydrate antigen 19-9. Computed tomography revealed a strongly enhanced solid peripheral mass with an intracystic component in the pancreatic tail (Figure A, arrow). Magnetic resonance imaging revealed a cystic lesion on the T2 image surrounded by a solid component with density and intensity levels similar to those in the spleen parenchyma (Figure B, arrow). Endoscopic ultrasonography showed a solid hyperechoic 20-mm mass and an intracystic hypoechoic component showing stronger enhancement by Sonazoid (MSD Inc) than the pancreatic parenchyma (Figure C, arrow). Laparoscopic distal pancreatectomy was used for diagnosis. Pathological examination revealed a white and red sinus of the ectopic spleen in the pancreatic tail, with a unilocular cyst lined with stratified squamous epithelium, indicating an epidermal cyst in the intrapancreatic accessory spleen (Figure D, arrows). Most epidermal cysts in the intrapancreatic accessory spleen cases are found incidentally, typically as single monolobular cystic lesions in the pancreatic tail with a thickened cystic wall or solid components identical in density to the spleen on imaging examinations, making a definite preoperative diagnosis extremely difficult, resulting in unnecessary surgical intervention.

Amyand's hernia; a case report in King Fahad Hospital, Medina

Background: Hernia is the protrusion of an organ or its fascia through the wall of a containing cavity. Ventral abdominal and inguinal hernias typically contain bowel or omentum; only rarely and incidentally the appendix is discovered within the herniated region known as Amyand's hernia (AH). Case Presentation: A 72-year-old male patient with a past surgical history of bilateral hernia repair and prostatectomy presented to the emergency department complaining of lower abdominal and severe scrotal pain with progressive scrotal swelling for 4 months associated with urinary retention and anorexia. On examination, the right scrotum was hugely enlarged and severely tender. Computed tomography (CT) concluded a large (wide neck 7 cm) right inguinal hernia causing mass effect on the urethra, intra-hernia appendix with radiological signs of acute inflamed appendix. The patient was admitted to the general surgical ward and underwent appendectomy and hernia mesh repair. The patient was observed for 1 week and no postoperative complications were seen. The patient was discharged on post-operative day 7 and followed up in the outpatient clinic. Conclusion: A definitive preoperative diagnosis of asymptomatic AH is rare as most cases are usually diagnosed during surgery. CT abdomen and pelvis remains the imaging modality of choice with groin mass or symptomatic hernia.

Schwannoma of Cervical Sympathetic Chain

Schwannomas may occur spontaneously or in the context of a familial tumour syndrome such as neurofibromatosis type 2 (NF2), schwannomatosis and Carney's complex. Schwannoma arising from the cervical sympathetic chain is an uncommon benign nerve tumour and is a diagnostic challenge. This tumour most often presents as an asymptomatic solitary neck mass, with slow-growing and rare malignant degeneration. Definitive pre-operative diagnosis may be difficult and investigations are not usually helpful. Diagnosis relies on clinical suspicion and confirmation is often obtained using surgical pathology. Surgical excision is the treatment of choice for this tumour, with recurrence being rare. Horner’s syndrome is a common postoperative neurological consequence but does not appear to cause problems to the patient. we describe our experience with clinical presentation, surgical management, and the outcome of a patient who presented with this pathology.

TU4.3 Caecal volvulus: A District General Hospital Experience and Review of the Literature

Abstract Aim Caecal volvulus (CV) is an uncommon cause of large bowel obstruction with potential for complications such as ischaemia, and perforation. Prompt diagnosis and treatment only will ensure better outcomes. We aim to describe our experience in the largest series of CV reported in the United Kingdom. Methodology This was a retrospective study of 16 consecutive patients diagnosed with CV between March 2017 and March 2020. Results Out of 16 patients, 11 were female, with a median age of 64 (range 33–80) years. All patients presented with abdominal pain and vomiting. An initial diagnosis of bowel obstruction was made only in 8 patients (50%). Computed tomography (CT) scan of the abdomen and pelvis correctly diagnosed CV in fourteen (87.5%). Fifteen patients (94%) underwent surgical intervention. All but one (n=14,93.4%) underwent laparotomy, and one patient (6.6%) underwent successful laparoscopic intervention. Right hemicolectomy was performed in all operated patients, and fourteen patients (93.4%) had primary anastomosis. Twelve patients (80%) had one or other form of morbidity. Seven patients (47%) and three patients (20%) had grade II and III (Clavien-Dindo Classification) complications respectively with a median hospital stay of 10 (range 1–49) days. One patient (6.7%) managed conservatively was deemed to be futile. There was no postoperative mortality. Conclusion CV can present with non-specific symptoms, and a definite preoperative diagnosis is only possible with the aid of CT. Open resectional procedures with primary anastomosis is the most favoured approach in management, though laparoscopic access is also feasible in fit patients.

Giant luteinized follicular cyst of pregnancy

Functional cysts usually do not cause symptoms or require surgical intervention. We reported a 17-year-old primigravida, gestational age of 10 weeks and 2 days, and ultrasound showing anechoic cyst in the right parauterine region without septa, with a larger diameter of 13.5cm, 632ml, and Doppler color without peripheral vascularization. The patient was oligosymptomatic during gestation. At 37 weeks and 6 days, gestation was interrupted, when the cyst had 2600 ml by ultrasonography. Fetal extraction was performed by cesarean delivery, and a large adnexal cyst visualized on the right was removed. The histopathological analysis of the surgical specimen revealed a cystic lesion coated by luteinized cells with discrete hyperchromatic and slightly pleomorphic nuclei, with underlying fibrous stroma with sparse luteinized cells, characterizing a giant luteinized follicular cyst of pregnancy. The prevalence of ovarian masses in pregnancy is rare, usually not exceeding 5 cm in diameter, and disappearing spontaneously in the second trimester. The patient in the case report had a cyst of 632 ml, increasing in volume to 2600 ml at the time of delivery. Definitive preoperative diagnosis of ovarian masses is still difficult, and predictive criteria for malignancy include the use of tumor markers, ultrasound, and Doppler. The association of these tests should guide the clinician to define the best time for surgical intervention. The association of these tests should guide the clinician to define the best time for surgical intervention.

Distal ureteral atresia – an embryological dilemma

Introduction: Distal ureteral atresia is a rare urinary tract anomaly generally associated with ipsilateral renal dysplasia and abnormalities such as multicystic dysplastic kidney, hydronephrosis and megaureter in the contralateral kidney. Despite burgeoning investigation modalities, definitive preoperative diagnosis of this condition is rarely feasible, also the embryological disarray of events that result in the development of this anomaly and the associated malformations is not clearly understood. Case presentation: We hereby report two cases of distal ureteral atresia and discuss the diversity in their presentations, diagnosis, atypical associations and management and review the possible embryological mal-development. Conclusion: Distal ureteral atresia with urogenital sinus as in Case 1 has not been documented so far and a plausible embryological explanation is deduced regarding its occurrence. The course of the affected kidney following timely and adequate relief of obstruction in Case 2 is depicted, highlighting the eventual management. Level of evidence: Not applicable

Rare but Real Presentation of Pancreatic Cystic Tumor

Cystic tumors of the pancreas are rare neoplasms. These tumors are frequently detected incidentally and a definitive preoperative diagnosis remains challenging. Because of widespread use of high quality cross-sectional imaging, pancreatic cystic neoplasms are being diagnosed with increasing frequency. This heterogeneous group of tumors is important because of their high cure rate as well as frequent confusion with the commoner pancreatic pseudocyst. We present a 69-year-old man with vague abdominal pain and loose motion for 3 months. Firstly, this case was misdiagnosed radiologically as pancreatitis with infected pseudocyst. From endoscopic diagnosis, pancreatico-gastrostomy fistula was found and biopsy taken from cyst wall. Histology report showed mucinous adenocarcinoma of pancreas. This was managed by excision of tumor and partial gastrectomy and local resection of transverse colon. It is rare but real presentation of pancreatic cystic tumor.

Fine Needle Aspiration Cytology of Giant Cell Tumour of Tendon Sheath

Introduction: Giant Cell Tumour of Tendon Sheath (GCTTS), also known as localised nodular tenosynovitis, is a slow growing benign soft tissue tumour arising from synovium of tendon sheath, bursa or joint. Clinically, the lesions occur as skin-coloured nodules typically on the extremities. These tumours occur more frequently on the upper limbs especially hands (77%) where they form the second most common tumour following simple ganglion cyst. Aim: To describe the cytomorphologic findings in GCTTS and their histopathological features. Materials and Methods: This retrospective study was conducted at Department of Pathology, ESI Hospital, Delhi, India, in 12 diagnosed GCTTS cases for their cytological features from January 2015 to December 2017. Fine Needle Aspiration Cytology (FNAC) was performed with a 22-gauge needle attached to a 10 mL syringe. Smears were air-dried and stained with Giemsa stain. Cytomorphology of all the selected cases were analysed and descriptive statistics were used to evaluate the cases. Results: A total of 12 cases of GCTTS were retrieved. Diagnosis of GCTTS was made by FNAC in all the cases and confirmed by histopathological examination in half of the cases. The mean age of presentation was 39 years. Of these, 8 (66.67%) were women and 4 (33.33%) were men. The lesions were found most commonly over the index finger (n=5) followed by the ring finger (n=3), thumb (n=2), middle finger (n=1) and little finger (n=1). The most frequent clinical presentation was a painless, nodular, slow growing firm swelling over the finger. FNAC revealed cellular smears with few clusters and numerous scattered stromal cells along with interspersed multinucleated giant cells. Conclusion: A definitive preoperative diagnosis of GCTTS obtained through FNAC helps in formulating appropriate treatment plan. Histopathologic examination will confirm the cytological diagnosis and can help to predict recurrence by providing information on the resection margin, any satellite nodules, variable cell types and mitotic activity.

Unclear retroperitoneal tumors, an interdisciplinary challenge - A case report and review of the literature.

Introduction and importanceUnclear retroperitoneal tumors impose major challenges for clinicians. Tumors can originate primarily from retroperitoneal tissue or secondarily invade into the retroperitoneum. While benign lesions also occur, malignant tumors are far more common. Clinical presentation depends on replacement or invasion of other organs and is therefore highly variable. The heterogeneous tumor composition makes a definitive preoperative diagnosis difficult. Surgical resection is the gold standard for treatment but often proves challenging due to frequent involvement of large retroperitoneal vessels.Case presentationWe present the case of a 70-year old woman diagnosed with a large, unclear retroperitoneal tumor. Initial clinical symptoms were increasing dyspnea and dysphagia in our clinic. Gastroenterologic and cardiologic workup was unremarkable. Computed Tomography (CT) revealed a large retroperitoneal mass in the right upper abdomen with severe displacement of the inferior vena cava and renal veins. The patient was scheduled for primary tumor resection. The procedure was challenging due to the vessel involvement and large blood pressure alterations during tumor mobilization. The post-op pathologic workup then revealed the rare finding of a completely resected paraganglioma. The post-surgical course was uneventful. One year after diagnosis, the patient is relapse-free.Clinical discussionAmong retroperitoneal tumors, paragangliomas and pheochromocytomas are rare tumor entities. Asymptomatic, sporadic disease is hard to identify preoperatively and can cause unexpected complications in the OR. An experienced team is crucial in achieving best short- and long-term outcomes.ConclusionThis case impressively shows the challenges of retroperitoneal tumors and the importance of interdisciplinary work in these cases.

Jejuno-Ileal tumors: a retrospective study

Background: Primary tumors of the jejunum and ileum are rare and this segment of gastrointestinal tract is relatively inaccessible to conventional endoscopy, leading to a delay in diagnosis. Due to its rarity, data of primary jejunoileal tumors is still scarce, especially in India where diagnostic modalities like capsule endoscopy is not widely available. Herein we aim to discuss the clinico-radiologic findings, pathology and surgical management of such tumors. Methods: Of the total 51 small bowel resections done in our institute during the period from year 2012 to 2015, 14 patients were identified who were diagnosed with jejunoileal benign/malignant jejunoileal tumors. Records were analysed with respect to patient demographic data, clinical features, radiologic findings, surgical management, histopathology and postoperative outcomes.Results: Jejunoileal tumors are more common in males (77%) and first presentation was intestinal obstruction (50%) in majority of patients. A definite preoperative diagnosis based on radiologic/endoscopic means was possible in six patients (46%). Patients were operated and laparoscopic group showed superior outcomes in terms of postoperative complications. Conclusions: Jejunoileal tumors are an infrequent finding in surgical practice. In our study malignant tumors were more common in proximal small bowel. Computed tomography (CT) enterography can detect small bowel lesions with low sensitivity but allows evaluation of lymphadenopathy/distant metastasis. Laparoscopic resection allows initial staging and has the advantage of early recovery, less wound infection rates and better cosmesis.

Submucosal Giant Lipoma of the Colon as an Unusual Cause of Partial Intestinal Occlusion: Report on Seven Consecutive Cases.

Colonic lipomas begin to be symptomatic when they reach a certain size, although the presentation can vary. In this study, we aimed to evaluate our experiences with the management of patients who presented with symptomatic giant colonic lipomas. The data of 7 patients with single colonic lipoma were retrospectively reviewed. The following data were evaluated: age, gender, clinical and diagnostic findings, American Society of Anesthesiologists (ASA) score, operative findings, postoperative complications, mortality, hospital stay duration, and hospital readmission. The diagnosis of colonic lipoma was established by computed tomography (CT). In this study, 4 (57.1%) of 7 patients with colonic lipoma were female, and 3 (42.9%) were male. The mean age was 56.7 years (range, 45-69). The main symptoms were abdominal pain (100%), and constipation (71.4%). The findings of intestinal occlusion detected on CT confirmed the diagnosis in all patients. Colon lipoma was located in the ascending colon in 2 patients, in the hepatic flexure in 2 patients, in the transverse colon in 2 patients, and in the cecum in 1 patient. The surgical procedure was uneventful in all patients. Four (57.1%) patients underwent laparoscopic colonic resection, while in the remaining 3 (42.9%) patients, a laparotomy was performed. The mean operating time was 185.7 min (150-210). Length of stay was 7.1 days (6-10), with no mortality. The mean diameter of the lesions was 7.4 cm (6-9). At a 6-month follow-up, all patients were asymptomatic with no signs of recurrence. Although colon lipomas are rare, they are of great importance because they can be symptomatic and can be confused with colon malignancies in the differential diagnosis. Being able to make a definitive preoperative diagnosis will change the surgical strategy. A minimally invasive surgical approach should be employed to resect symptomatic colonic lipomas with an experienced surgical team in eligible patients whenever possible.
