    Abstract Introduction and importance: Meddle segment pancreatectomy (MP) is a parenchyma-sparing surgical procedure that has recently been proposed for treatment of benign or attenuated malignant tumors. However, this procedure is not fully recognized.
    Case presentation: We herein report 3 patients undergoing MP for tumors of pancreas body and tail. The first patient was a 38-year-old woman with a neuroendocrine tumor, the second was a 42-year-old woman with a serous cystic neoplasm and the 3rd patient was 57 years old, with mucinous cystadenoma. A MP with spleen preservation was performed in the 3 patients, with ligatures of splenic vessels in the first patient. Only one patient developed a pancreatic fistula, which was managed medically. In our 3 patients, no endocrine or exocrine insufficiency was observed, but the first patient showed a disease recurrence with liver metastasis 3 years after surgery.
    Clinical discussion: Middle pancreatectomy can not only avoid the pancreatic effects of extensive resections, but it is also a technique that has a very low operative or postoperative mortality rate.
    Conclusion: MP is a feasible, safe procedure with several advantages, but which unfortunately remains rarely practiced.

    Abstract Rectal malignant melanomas (RMM) are remarkably uncommon, the rectal location represents less than one percent of all rectal cancer. Because of its low global survival rate, the surgical strategy is a subject of controversy for attaining a r0 resection. the palliative treatment is also debateable, but recently; radiotherapy and immunotherapy became the preferred treatment and offer the best outcome. to ensure r0 resection, abdominoperineal resection (apr) is considered the main surgical option, but because of its morbidity and functional limitations, local excision techniques such as endoscopic mucosal resection (emr) combined with chemoradiotherapy are being increasingly performed to preserve the quality of life and reduce local recurrence rate. In this report, we evaluate the place that apr still keeps as surgical procedure in comparison to partial excision. we report a case of a 72 years old patient, who presented rectal syndrome with rectorrhagia for 2 months, the diagnosis of localized rectal melanoma was confirmed by endoscopy, magnetic resonance imaging, histological analysis tissue with immunohistochemistry. the procedure strategy was a surgical treatment with apr. After a long recurrence-free survival period, the patient develops local recurrence and immunotherapy-resistant metastasis.

    Abstract Primary hepatic lymphoma (PHL) is a very rare malignancy and constitutes 0.016% of all cases of non-Hodgkin's lymphoma and 0.4% of extranodal non-Hodgkin's lymphoma. We describe a rare case of primary hepatic lymphoma presenting as liver abscess which was complicated with the development of a hepatogastric fistula. A 58-year-old man presented with clinical signs of sepsis, high-grade fever, right upper abdominal pain, and weight loss which had progressed in the past 8 months. Noncontrast abdominal computed tomography (CT) revealed a heterogeneously hypodense lesion in the left lobe of the liver with multiple air foci within, which are seen to extend into the body of the stomach. The patient was initially misdiagnosed as a case of rupture of liver abscess into the stomach. Postoperative liver biopsy examination confirmed a diagnosis of diffuse large B-cell lymphoma. Systemic staging revealed no evidence of nodal or bone marrow involvement, so PHL was diagnosed. Chemotherapy was initiated, but discontinued due to the patient's general condition. Finally, the patient succumbed to neutropenic fever following chemotherapy. Here, we present the exceptional case of a primary hepatic lymphoma with an unusual complication, a hepatogastric fistula, and try through the existing literature to show the difficulties involved in diagnosis and treatment.

    Abstract Bezoars are rare causes of gastrointestinal obstruction. Basically, they are of four types: trichobezoars, phytobezoars, pharmacobezoars, and lactobezoars. Some rare types of bezoars are also known. In this article a unique case of plastic bezoars is presented. We describe a girl aged 14 years who ingested large amounts of plastic material used for knitting chairs and charpoys. The conglomerate of plastic threads, entrapped food material and other debris, formed a huge mass occupying the whole stomach and extended into small bowel.
