Effect of Robotic Inferior Mesenteric Artery Ligation Level on Low Anterior Resection Syndrome in Rectum Cancer.

Background: Life expectancy of patients with rectal cancer is increasing day by day with innovative treatments. Low anterior resection syndrome (LARS), which disrupts the comfort of life in these patients, has become a serious problem. We aimed to evaluate the effect of high ligation (HL) and low ligation (LL) techniques on LARS in rectal cancer surgery performed with the robotic method. Materials and Methods: The data of patients diagnosed with mid-distal rectal cancer between 2016 and 2021 who underwent robotic low anterior resection by the same team in the same center with neoadjuvant chemoradiotherapy were retrospectively evaluated. Patients were divided into two groups as those who underwent HL and LL procedures. Preoperative, 8 weeks after neoadjuvant treatment, 3 and 12 months after ileostomy closure were evaluated. Results: A total of 84 patients (41 HL, 43 LL) were included in the study. There was no statistically significant difference between the demographic characteristics and pathology data of the patients. Although there was a decrease in LARS scores after neoadjuvant treatment, there was a statistically significant difference between the two groups at 3 and 12 months after ileostomy closure (P: .001, P: .015). Conclusions: In patients who underwent robotic low anterior resection, there is a statistically significant difference in the LARS score in the first 1 year with the LL technique compared with that of the HL technique, and the LL technique has superiority in reducing the development of LARS between the two oncologically indistinguishable methods.

Coexistence of tuberculosis and extranodal marginal zone lymphoma of the thyroid gland: Case report and literature review.

Introduction: Primary thyroid tuberculosis (TB) is rare even in countries where TB disease is endemic, with the prevalence ranging from 0.1 to 1.15%. Primary thyroid lymphoma is uncommon, and the majority of lymphomas arising in the thyroid gland are non-Hodgkin's lymphomas of B-cell origin, of which about 25% is extranodal marginal zone B cell lymphoma (MALToma). Case presentation: An 86-year- old Turkish female patient with thyroid nodules and cervical lymphadenopathies presented with large multinodular goiter and compressive symptoms. Total thyroidectomy and central lymph node dissection were performed. The revised histological and immunohistochemical revealed the coexistence of thyroid TB and MALToma. The patient received an anti-TB treatment for six months before a revised histopathological examination. About seven months after anti-TB treatment, the patient died due to an unknown cause. Clinical discussion: Although six cases of thyroid TB and papillary thyroid cancer have been documented in the medical literature, no cases of TB and MALToma coexistence have been published so far, to our knowledge. Another essential feature of this study is that the initial pathological examination was reported as thyroid TB. A subsequent re-examination revealed that the patient had both TB and MALT lymphoma. Conclusion: We discuss this rare association and the dilemma encountered in the diagnosis and management of this patient with a review of the literature.

Can the surgeon prolong the remaining life of the patient in pancreaticoduodenectomy surgery? or Is the surgeon helpless?

BACKGROUND: We aimed to evaluate the effects of R0 and R1 resections after pancreatic surgery. METHODS: Data of 130 patients were evaluated. Re-resection was performed in patients who were found to have R1 resection after frozen section (FS). Overall survival (OS), disease free survival (DFS) among patients with R1 resection in paraffin section (PS) (n:28, Group1) and patients who underwent re-resection after FS and achieved the R0 resection goal in PS (n:16, Group 2) (DFS), local recurrence and systemic metastasis results were compared. RESULTS: Tumor diameter, differentiation, age and complications were found to negatively affect OS. It was observed that DFS increased (p:0.02) and local recurrence rates decreased (p:0.037) in group 2 compared but there was no difference between the two groups in terms of OS (p:0.420) and systemic metastasis (p:0.467). CONCLUSIONS: R0 resection obtained by surgical margin resection of the neck in pancreatic head adenocarcinomas decreases local recurrence and increases the duration of DFS. However, it has no effect on preventing OS and systemic metastasis.

Intestinal Obstruction Due to Idiopathic Sclerosing Encapsulating Peritonitis: A Case Report.

INTRODUCTION: Sclerosing encapsulating peritonitis (SEP) is characterized by partial or complete encasement of small intestine by a thick fibrocollagenous membrane. Depending on underlying causes, SEP is divided into primary and secondary forms. Idiopathic SEP is also called idiopathic or abdominal cocoon syndrome. Herein we presented a case of idiopathic SEP. CASE PRESENTATION: A 90-year-old male patient presented to our emergency department with signs and symptoms of intestinal obstruction and dehydration. Physical examination findings, patient's age and plain abdominal radiography were consistent with tumoral obstruction or viscus perforation. Explorative laparotomy revealed a fibrous capsule encasing intestines as well as dense adhesions between intestinal loops. Since the overall condition of the patient was not well enough to allow a wide dissection and membrane excision, the operation was terminated after performing a limited loop ileostomy. Unfortunately, the patient was lost due to organ failure at the postoperative period. CONCLUSIONS: Despite advances in radiological techniques, the exact diagnosis in many cases is still made according to intraoperative findings and histopathological properties of the excised membrane. While some cases of SEP remain asymptomatic for years, most cases are characterized by recurrent bouts of acute, subacute or chronic intestinal obstruction. To our knowledge, the case presented here is the oldest patient with idiopathic SEP in the literature.

The effect of laser epilation on recurrence and satisfaction in patients with sacrococcygeal pilonidal disease: a prospective randomized controlled trial.

BACKGROUND: The primary aim of this prospective study was to investigate the effects of laser epilation on patient satisfaction and recurrence in patients who underwent pilonidal sinus surgery. METHOD: Sixty patients scheduled for pilonidal sinus surgery in our clinic between 2011 and 2012 were enrolled in this prospective randomized controlled study. Patients were divided in two groups of 30 patients each. Only the Karydakis flap reconstruction technique was performed in the first group. Two sessions of laser epilation were applied in the second group in addition to Karydakis flap reconstruction. The patients in the second group underwent laser epilation 2 weeks before and 3 weeks after the surgery for a total of 2 times in a private office. RESULTS: There were no statistically significant differences between the groups in terms of age, gender, smoking usage, ASA Score, duration of patient's complaints, BMI and hospital stay. There were no statistically significant differences between the groups in terms of surgical site infection, wound separation, abscess formation at the any time postoperatively. There were statistically significant differences between the two groups in the first week post operation considering the VAS pain score (P<0.03) and VAS satisfaction score (P<0.01). While there were statistically significant differences between the two groups in the first month post operation considering the VAS pain score (P<0.0001), there were no statistically significant differences between the groups in terms of VAS satisfaction score in the first and three month postoperatively. In the telephone interviews done 1 year after the surgery, recurrence were detected in 4% of first group and in 20% of second group. Recurrence rates were significantly higher in the second group (P=0.045). CONCLUSION: Our results show that laser epilation does not reduce the relapse rates in pilonidal sinus surgery, as expected. It is obvious that prospective randomized studies need to be held on this subject.

Pancreatic extragastrointestinal stromal tumor: A case report and comprehensive literature review.

AIM: To provide an overview of the literature on pancreatic extragastrointestinal stromal tumors (EGISTs). METHODS: We report a case of pancreatic EGIST and review published studies on pancreatic EGIST accessed via the PubMed, MEDLINE, Google Scholar, and Google databases. The keywords used were "pancreas and GIST", "pancreas and extra GIST", "pancreas and gastrointestinal stromal tumor", and "pancreas and extragastrointestinal stromal tumor". Literature reviews and/or duplicate studies were excluded. The search included articles published in the English language between January 1, 2000 and May 15, 2014. RESULTS: From our literature survey, 30 manuscripts on pancreatic EGISTs were considered, of which 27 met the search criteria and three were excluded. The studies involved 30 patients (15 men, 15 women) with a mean age of 55.3 ± 14.3 years (range 30-84 years). The mean age of the male patients was 50.8 ± 13.7 years (range 30-84 years); that of the female patients was 59.9 ± 13.3 years (range 38-81 years). Tumor dimensions were obtained for 28 cases (mean 114.4 ± 78.6 mm; range 20-350 mm). Tumors were diagnosed incidentally in 23.3% of patients; abdominal discomfort and weight loss were the major complaints in symptomatic patients. Risk of aggressive behavior according to Fletcher criteria was determined in 25 of 30 patients (68%: high risk, 28%: intermediate risk, 4%: low risk). Histopathological examination revealed the presence of spindle cells in 96.1% of cases; CD117 and CD34 were present immunohistochemically in 96.6% and 84% of patients, respectively. The most common surgical procedures were distal pancreatectomy with splenectomy (n = 9) and pancreaticoduodenectomy (n = 7). The total follow-up period for the 28 patients ranged from 3-66 mo, during which locoregional or distant metastases were diagnosed in six patients and two patients died. CONCLUSION: Studies on EGISTs have only been published in the last decade. The lack of studies with large patient cohorts and long-term follow-up limits evidence-based commentary. In theory, each case should be assessed individually and further genetic and immunohistochemical studies are needed.

Hydatid cyst of the pancreas: Report of an undiagnosed case of pancreatic hydatid cyst and brief literature review.

AIM: To overview the literature on pancreatic hydatid cyst (PHC) disease, a disease frequently misdiagnosed during preoperative radiologic investigation. METHODS: PubMed, Medline, Google Scholar, and Google databases were searched to identify articles related to PHC using the following keywords: hydatid cyst, hydatid disease, unusual location of hydatid cyst, hydatid cyst and pancreas, pancreatic hydatid cyst, and pancreatic echinococcosis. The search included letters to the editor, case reports, review articles, original articles, meeting presentations and abstracts that had been published between January 2010 and April 2014 without any restrictions on language, journal, or country. All articles identified and retrieved which contained adequate information on the study population (including patient age and sex) and disease and treatment related data (such as cyst size, cyst location, and clinical management) were included in the study; articles with insufficient demographic and clinical data were excluded. In addition, we evaluated a case of a 48-year-old female patient with PHC who was treated in our clinic. RESULTS: A total of 58 patients, including our one new case, (age range: 4 to 70 years, mean ± SD: 31.4 ± 15.9 years) were included in the analysis. Twenty-nine of the patients were female, and 29 were male. The information about cyst location was available from studies involving 54 patients and indicated the following distribution of locations: pancreatic head (n = 21), pancreatic tail (n = 18), pancreatic body and tail (n = 8), pancreatic body (n = 5), pancreatic head and body (n = 1), and pancreatic neck (n = 1). Extra-pancreatic locations of hydatid cysts were reported in the studies involving 44 of the patients. Among these, no other focus than pancreas was detected in 32 of the patients (isolated cases) while 12 of the patients had hydatid cysts in extra-pancreatic sites (liver: n = 6, liver + spleen + peritoneum: n = 2, kidney: n = 1, liver + kidney: n = 1, kidney + peritoneum: n = 1 and liver + lung: n = 1). Serological information was available in the studies involving 40 patients, and 21 of those patients were serologically positive and 15 were serologically negative; the remaining 4 patients underwent no serological testing. Information about pancreatic cyst size was available in the studies involving 42 patients; the smallest cyst diameter reported was 26 mm and the largest cyst diameter reported was 180 mm (mean ± SD: 71.3 ± 36.1 mm). Complications were available in the studies of 16 patients and showed the following distribution: cystobiliary fistula (n = 4), cysto-pancreatic fistula (n = 4), pancreatitis (n = 6), and portal hypertension (n = 2). Postoperative follow-up data were available in the studies involving 48 patients and postoperative recurrence data in the studies of 51 patients; no cases of recurrence occurred in any patient for an average follow-up duration of 22.5 ± 23.1 (range: 2-120) mo. Only two cases were reported as having died on fourth (our new case) and fifteenth days respectively. CONCLUSION: PHC is a parasitic infestation that is rare but can cause serious pancreato-biliary complications. Its preoperative diagnosis is challenging, as its radiologic findings are often mistaken for other cystic lesions of the pancreas.

Isolated cavernous hemangioma: a rare benign lesion of the stomach.

Gastric cavernous hemangioma is a relatively rare benign gastric disease. Here we report the case of a 25-year-old male patient who had been admitted complaining of epigastric pain and hematemesis. Preoperative imaging indicated that the mass lesion palpated in the epigastric region was a probable mesenchymal tumor of gastric origin. Due to the hypervascular nature and submucosal localization of the mass, we did not obtain definitive preoperative diagnosis by endoscopic biopsy. The histologic diagnosis of cavernous hemangioma was confirmed by post-resection histopathologial evaluation of the mass.

Ectopic bone formation and extramedullary hematopoiesis in the thyroid gland: report of a case and literature review.

This purpose of this article is to document ectopic bone formation (EBF) and extramedullary hematopoiesis (EMH) in thyroidectomy specimens. We present a case of multinodular goiter with EMH and EBF, as well as a literature review of studies published in the English language on EMH and/or bone formation in the thyroid gland, accessed through PubMed and Google Scholar databases. Thirteen published cases of EMH and/or EBF in the thyroid gland were evaluated, and a case of multinodular goiter with histopathologically proven EMH and EBF in a 54-year-old woman is herein presented. In the reviewed literature, 12 patients were women, and 1 was a man (age range, 28-82 years; median, 56.46 +/- 18 years). EMH was histopathologically detected in 8 patients, EMH and EBF were detected in 4 patients, and only bone formation was detected in 1 patient. Although a solitary nodule was detected in 7 patients, multinodular goiter was detected in 6 patients. Fine needle aspiration cytology was used in the preoperative period to arrive at a diagnosis in 6 of the 13 patients, but it was not possible to obtain proper biopsy material in the remaining patients. Although no previously known hematologic disease was detected in 11 patients, 2 were known to have myelofibrosis in the preoperative period. When EMH is pathologically detected in the thyroid, the question of whether there is an underlying hematologic disease in the patient must be investigated. In addition, it must be kept in mind during fine needle aspiration cytology and frozen section examinations that EMH maybe among the differential diagnoses for anaplastic thyroid cancers.
