An unusual clinical presentation of colonic lipomatosis: A case report.

INTRODUCTION: Colonic lipomatosis is defined as a poorly circumscribed, non-capsulated fat accumulation in the submucosal layer of the colonic wall. Clinical presentation varies from asymptomatic to acute surgical complications. PRESENTATION OF CASE: We report the case of a 79-year old male who arrived at the Emergency Department complaining of worsening abdominal pain, fever and nausea. A CT scan revealed a periappendicular abscess extended to the ileocecal valve and also the presence of diffuse intramural fatty tissue of the ascending colon. The patient underwent surgery and a right hemicolectomy was performed. The final histological exam confirmed the diagnosis of gangrenous appendicitis with diffuse abscessualization of the ileocecal valve and the presence of submucosal lipomatosis of the ICV extending to the ascending colon. Patient was discharged at 11th-POD. DISCUSSION: Acute appendicitis can represent a complication, although rare, of colonic lipomatosis. The underlying mechanism can be explained by the obstruction of the stool discharge from the appendix caused by the thickened colonic wall due to lipomatosis. Despite the lack of established guidelines on the management of colonic lipomatosis, surgery remains the preferred treatment in case of acute complications. CONCLUSION: Acute appendicitis is a rare clinical manifestation of colonic lipomatosis. As in the case of other acute complications, such as intussesception, surgery remains the preferred therapeutic approach.

Case report: successful endoscopic removal of a large rectal foreign body.

Incidence of emergency access due to retained large rectal foreign bodies is increased in the last years. Such situations are a challenge because often, due to their size and physical characteristics, the large foreign bodies of the rectum cannot be extracted manually or by endoscopy, thus requiring surgery, as reported in the literature. We report a case of a 59-old male with a retention of a large vegetable rectal foreign body (whole eggplant) successfully subjected to endoscopic removal without the need for surgery.

Transjejunal Laparoscopic-Assisted ERCP: a Technique to Deal with Choledocholithiasis After Roux-En-Y Reconstruction.

INTRODUCTION: In Roux-en-Y reconstructions, choledocholithiasis could represent a really challenging condition to treat which can be treated by a surgical-assisted ERCP. Only six cases of transjejunal laparoscopic-assisted ERCP (LAERCP) can be found in literature to date and no large series are present. METHODS: A young woman who had undergone a laparoscopic Roux-en-Y gastric bypass 2 years earlier came complaining recurrent abdominal pain. Radiologic exams found stones in the common bile duct and no signs of internal hernia. We therefore decided to perform a transjejunal LAERCP finding a concomitant internal hernia in the Petersen's space which was repaired at the same time. RESULTS: The post-operative course was uneventful. CONCLUSION: Transjejunal LAERCP is a feasible technique to deal with choledocholithiasis, and it allows at the same time to identify and treat concomitant conditions like internal hernias.

The effect of fruits and vegetables on urinary stone risk factors.

BACKGROUND: The overall effect of fruit and vegetable intake on urinary stone risk profile is not yet known. METHODS: We studied the effect of a two-week period of fruit and vegetable elimination on urinary stone risk profile in 12 normal adults, and of supplementing the diet with a fair quantity of low-oxalate fruits and vegetables in 26 idiopathic calcium stone formers characterized by hypocitraturia and a very low fruit and vegetable intake in their usual diet. RESULTS: In the normal subjects, the elimination of fruits and vegetables from the diet decreased the urinary excretion of potassium (-62%), magnesium (-26%), citrate (-44%) and oxalate (-31%), and increased that of calcium (+49%) and ammonium (+12%) (P < 0.05 for all). The relative saturation for calcium oxalate and calcium phosphate increased from 6.33 to 8.24 (P = 0.028), and from 0.68 to 1.58 (P = 0.050), respectively. In the hypocitraturic stone formers, the introduction of these foods in the diet increased urinary volume (+64%), pH (from 5.84 to 6.19), excretion of potassium (+68%), magnesium (+23%), and citrate (+68%), while it decreased the excretion of ammonium (-18%) (P < 0.05 for all). The relative saturation for calcium oxalate and uric acid fell from 10.17 to 4.96 (P < 0.001), and from 2.78 to 1.12 (P = 0.003), respectively. CONCLUSION: The total elimination of fruits and vegetables in normal subjects brings about adverse changes in the urinary stone risk profile that are only partially counterbalanced by a reduction in oxalate. In contrast, the addition of these foods to the diet of hypocitraturic stone formers not used to eating them not only significantly increases citrate excretion without affecting oxalate excretion, but also decreases calcium oxalate and uric acid relative saturation.
