Laparoscopic resection for Meckel's diverticulum causing intestinal obstruction.

Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal system with an estimated incidence of approximately 2% of the population. Although most cases are asymptomatic, it has the potential to create complications, such as hemorrhage, inflammation, intestinal obstruction, perforation, and intussusception. Meckel's diverticulum is generally diagnosed incidentally or upon investigation of unexplained gastrointestinal bleeding, perforation, inflammation, or obstruction for both pediatric and adult patients. Complications are often present as surgical emergencies and require resection of the diseased intestinal segment. In doubtful cases, laparoscopy should be the surgical method for both diagnosing and treating MD. Here we present a case of MD causing intestinal obstruction and that was treated by laparoscopic resection.

Laparoscopic splenectomy for a wandering spleen causing chronic pelvic pain.

Wandering spleen is a rare condition with a reported incidence of less than 0.5% in which the spleen migrates from its normal anatomical location to any other position in the abdomen. Women constitute 80% of cases and one third of the overall patients are children. It has different clinical presentations such as asymptomatic, painless mass in the abdomen, intermittent abdominal pain and acute abdomen due to torsion of the vascular pedicle. Here we present a case of wandering spleen causing chronic pelvic pain. Laparoscopic splenopexy was the treatment choice but it could not be performed due to huge size of the wandering spleen.

Capillary refill time as a guide for operational decision-making process of autoimmune pancreatitis: Preliminary results.

AIM: To investigate the efficacy of a novel intraoperative diagnostic technique for patients with preliminary diagnosis of autoimmune pancreatitis (AIP). METHODS: Patients with pancreatic surgery were reviewed to identify those who received a preliminary diagnosis of AIP between January 2010 and January 2014. The following data were collected prospectively for patients with a pathological diagnosis of AIP: clinical and demographic features, radiological and operative findings, treatment procedure, and intraoperative capillary refill time (CRT) in the pancreatic bed. RESULTS: Eight patients (six males, two females; mean age: 51.4 years) met the eligibility criteria of pathologically confirmed diagnosis. The most frequent presenting symptoms were epigastric pain and weight loss. The most commonly conducted preoperative imaging studies were computed tomography and endoscopic retrograde pancreaticodoudenography. The most common intraoperative macroscopic observations were mass formation in the pancreatic head and diffuse hypervascularization in the pancreatic bed. All patients showed decreased CRT (median value: 0.76 s, range: 0.58-1.35). One-half of the patients underwent surgical resection and the other half received medical treatment without any further surgical intervention. CONCLUSION: This preliminary study demonstrates a novel experience with measurement of CRT in the pancreatic bed during the intraoperative evaluation of patients with AIP.

Unclassified diffuse ductal cholangiocarcinoma; report of a case.

Cholangiocarcinoma (CCA) is the second most common malignant tumor of the liver. It is simply classified as intrahepatic and extrahepatic CCA (including perihilar and distal extra hepatic CCA) according to the anatomic localization. Various classification systems were described for staging cholangiocarcinoma. We represent an interesting case of cholangiocarcinoma which is in the shadow area of classification by involving intrahepatic, hilar, and distal extra hepatic bile ducts. To our knowledge, this is the first case in the literature with diffuse bile duct involvement.

Laparoscopic Appendectomy versus Mini-Incision Appendectomy in Patients with Lower Body Mass Index and Noncomplicated Appendicitis.

Laparoscopic appendectomy has become favored over open surgical methods for its association with decreased postoperative pain, more rapid return to daily activities, and improved cosmetic results. Mini-incision appendectomy was being performed in our clinic for a long time especially in patients with noncomplicated appendicitis and in patients with appropriate body mass index. Although laparoscopy presents obvious advantages especially for obese patients and young women, with respect to the results of our study, mini-incision appendectomy seems to be an alternative for selected patient groups.

A retained plastic protective cover mimicking malignancy: Case report.

INTRODUCTION: Cases of retained foreign bodies during surgery are more frequently seen in developing countries. Following surgical procedures, unintentionally retained foreign bodies can cause serious complications, in addition to medico-legal issues. PRESENTATION OF CASE: A 60-year-old man presented with abdominal cramps. He had previously undergone a laparoscopic radical right nephrectomy due to renal cell carcinoma. Abdominal tomography revealed a mass surrounding the main vascular structures with malignant features in the location of previously performed nephrectomy. Further evaluation of the mass was undertaken by PET/CT. Increased FDG uptake on the PET/CT scan suggested disease recurrence. Retroperitoneal lymph node dissection was performed. The dissection specimen was opened to determine the nature of the mass. Retained plastic foreign bodies were found. There were no malignant cells in the histopathological examination of the surgical specimen. DISCUSSION: A granulomatous reaction which is mainly responsible for morbidity occurs around the foreign bodies due to the inflammatory response. These granulomas may cause confusion during patient follow-up, especially in those who have undergone major abdominal surgery due to cancer. CONCLUSION: Following surgical resection for malignancy, unintentionally retained foreign bodies can produce a moderate increase in FDG uptake mimicking disease recurrence.

Inflammatory myofibroblastic tumor of the gallblader.

BACKGROUND: Inflammatory myofibroblastic tumors are rare benign tumors that can mimic malignancy. Their precise aetiology is unknown. They are seen more frequently in childhood and the most common involvement is seen in the lungs. Primary inflammatory myofibroblastic tumors of the gallbladder are rather infrequent. The present knowledge is based on case reports. CASE REPORT: A 66 year-old male patient presented to the hospital with complaints of abdominal pain, nausea and vomiting. Upon physical examination, a clinical picture of abdominal tenderness on the right upper quadrant of the abdomen was identified. Laboratory examinations revealed leukocytosis and hypochromic microcytic anaemia with an increased erythrocyte sedimentation rates and C-reactive protein levels. A mass almost completely filling the gallbladder was detected by imaging studies. The patient was operated on with a malignant preoperative diagnosis and underwent a liver resection of segments 4 and 5, which included a cholecystectomy. The histopathological examination of the surgical specimen revealed an inflammatory myofibroblastic tumor including many histiocytes stained positively with CD 68. CONCLUSION: Inflammatory myofibroblastic tumors can be localised in the gallbladder mimicking gallbladder cancer.

Primary malignant melanoma of the gallbladder: a case report and review of the literature.

Malignant melanoma is characterized by the ability of diffuse metastases. Since the first report of an isolated malignant melanoma case of the gallbladder, it is already controversial whether isolated cases are metastatic or primary tumors. A 49-year-old woman appealed to the emergency unit because of abdominal pain. Ultrasonography revealed increased thickness of the gallbladder wall and a lesion with surrounding fluid sized 12 mm without acoustic shadow, which arose from the gallbladder wall and was consistent with a polyp. Histopathologic evaluation of the surgical specimen after laparoscopic cholecystectomy revealed malign epithelial tumor consisting of atypical cells with large eosinophilic cytoplasm and dense melanin pigment within the cytoplasm of the tumor cells. As no other focus was identified as a result of the evaluation, the patient was diagnosed with primary malignant melanoma of the gallbladder. In this paper, we aimed to define our treatment modality for a case with isolated malignant melanoma of the gallbladder.

Surgical management of Mirizzi syndrome.

BACKGROUND/AIMS: Mirizzi syndrome is an unusual presentation of prolonged cholelithiasis. This study aimed to analyze the diagnostic methods, operative strategies, and outcome of the surgical treatment of patients with Mirizzi syndrome. METHODS: We retrospectively evaluated the patients with Mirizzi syndrome treated in our General Surgery Clinic. The data collected included demographic variables, clinical presentation, diagnostic methods, surgical procedures, and postoperative complications. RESULTS: The study included 13 male and 21 female patients, with a mean age of 67.2 years. The incidence of Mirizzi syndrome was determined as 0.6% (34/5632), and type II was more frequently observed (52.9%); no patient was determined as type IV. The incidences of types I and III were 35.2% and 11.7%, respectively. Among the preoperative diagnostic evaluations, ultrasonography was the initial imaging study that was performed in all patients. Computerized tomography, magnetic resonance cholangiopancreatography, and endoscopic retrograde cholangiopancreatography were the other radiological studies. Surgical procedures included cholecystectomy for 83% of the patients with type I. The remaining cases and 14 of the type II patients (77.7%) underwent choledochotomy and T-tube insertion following cholecystectomy. Four of the patients with type II variety and all of the type III patients underwent cholecystectomy and roux-en-Y hepaticojejunostomy. All of the patients had complete recovery, with a morbidity rate of 5.8%, and there was no hospital mortality. CONCLUSIONS: The essential part of the management of patients with Mirizzi syndrome is to determine the best surgical procedure in the preoperative period. In type I patients, simple cholecystectomy is generally enough, but sometimes T-tube insertion may be required, while the cases with types II-IV require more complex surgical approach, such as cholecystectomy and bilioenteric anastomosis. Roux-en-Y hepaticojejunostomy is an appropriate procedure with good outcome.
