: This systematic review, using pairwise and network meta-analyses, aimed to compare the intraoperative, short-term, and long-term postoperative outcomes of minimally invasive surgery (MIS) and open surgery (OS) for the management of pancreatic neuroendocrine tumors (pNETs). : Studies reporting on the effects of robotic, laparoscopic, and open surgery on pNETs published before November 2023 on PubMed, Scopus, and CENTRAL were analyzed. : Thirty-two studies with 5379 patients were included in this review, encompassing 2251 patients undergoing MIS (1334 laparoscopic, 508 robotic, and 409 unspecified MIS) and 3128 patients undergoing OS for pNETs management.

Fibrin glue and coats compromise the integrity of colonic anastomosis: an experimental trial on rats.

Background: Anastomotic leak remains a dreaded complication in colorectal surgery. Identifying optimal techniques that minimize its incidence is an active area of investigation. The aim of this experimental study was to evaluate the effect of commonly used hemostatic products on the integrity of colonic anastomoses.

Solitary Soft-Tissue Metastasis of a Pancreatic Adenocarcinoma 2 Years After Curative Resection: Report of a Rare Case and a Literature Review.

BACKGROUND Soft-tissue metastases from a primary carcinoma are rare lesions. They often are the first clinical manifestation of a previously unknown malignancy of an advanced stage, but may also be solitary in a setting of a recurrent disease. Generally, they are associated with poor prognosis and may be the source of diagnostic confusion both clinically and pathologically.

Effect of moxifloxacin on survival, lipid peroxidation and inflammation in immunosuppressed rats with soft tissue infection caused by Stenotrophomonas maltophilia.

In order to investigate the effect of moxifloxacin on survival, lipid peroxidation and inflammation in immunosuppressed rats with soft tissue infection caused by Stenotrophomonas maltophilia, 144 white male Wistar rats were randomized into six groups: Groups A and B received saline or moxifloxacin once per day, respectively; Groups C and D received saline or moxifloxacin twice per day, respectively, and Groups E and F received saline or moxifloxacin three times per day, respectively. Blood samples were taken at 6 and 30 hr after administration of S. maltophilia.

Abdominal aortic aneurysm with symptomatic cholelithiasis: report of a case treated by simultaneous endovascular aneurysm repair and laparoscopic cholecystectomy.

Asymptomatic cholelithiasis with abdominal aortic aneurysm (AAA) is one of few ideal fields for simultaneous "open" repair. In AAA cases with acute lithiasic cholecystitis, the simultaneous open repair is debatable due to increased possibility for prosthetic graft contamination. We report a case of a 78-year-old, ASA IV patient suffering from acute cholecystitis and concomitant (62 mm) AAA.

Spleen rupture due to primary angiosarcoma: a case report.

A case of a 79-year-old female with rupture of the spleen due to primary angiosarcoma is presented. Symptoms were non-specific. Diagnosis was based on histology postoperatively.

Carcinoma developing in ectopic pancreatic tissue in the stomach: a case report.

The development of pancreatic tissue outside the confines of the main gland, without anatomic or vascular connections between them, is a congenital abnormality referred to as heterotopic pancreas. A heterotopic pancreas in the gastrointestinal tract is usually discovered incidentally and the risk of its malignant transformation is extremely low. In this study, we describe the first case of endoepithelial carcinoma arising in a gastric heterotopic pancreas of a 56-year old woman in Greece.

Gastric perforation and death after the insertion of an intragastric balloon.

We report a case of a patient who presented with an acute abdomen 2 days after the insertion of an intragastric balloon system and discuss in detail the advantages and drawbacks of these devices in the therapy of morbid obesity. A 43-year-old morbidly obese man was admitted to the department of surgery in shock with a 2-h history of severe diffuse abdominal pain and the initial diagnosis of visceral perforation. The patient had been subjected to intragastric placement of an inflatable balloon 48 h prior to his presentation.

Morphological parameters of the superior articular facets of the atlas and potential clinical significance.

Background: Although remarkable investigations exist in regard to the morphology of the superior articular facets of the atlas in the literature, only a few data exist concerning the correlation of these facets with the age of the specimens.

Methods: The superior articular facets of the atlas were studied in 86 dried vertebrae. Several non-metric parameters were recorded, like presence of notches, grooves, complete or partial dissociation, rough surfaces as well as their morphology.

Ectopic papilla of vater in the stomach, blind antrum with aberrant pyloric opening, and congenital gastric diverticula: an unreported association.

We present an extremely rare combined congenital anomaly consisting of ectopic drainage of the common bile duct in the lesser curvature of the stomach, congenital gastric diverticula, blind antrum with aberrant pyloric opening, and redundant spleen. The diagnosis was made during routine endoscopy in a 35-year-old woman, who presented complaining for regurgitation and retrosternal burning in the last 4 years. To our knowledge this is the first description of this rare combination of congenital anomalies.

Modifications of coagulation and fibrinolysis mechanism in laparoscopic vs. open cholecystectomy.

Background/aims: The incidence of thromboembolic complications following laparoscopic cholecystectomy as well as the indication for prophylactic thrombophylaxis is still controversially discussed. The aim of this study is to evaluate the alterations of the coagulation and fibrinolytic mechanism after laparoscopic vs. open cholecystectomy.

Intraluminal intestinal administration of oxygenated perfluorocarbon improves acid-base and cardiopulmonary parameters after acute mesenteric ischemia. An experimental study in rabbits.

Purpose: The aim of this study was to evaluate the effects of the intraluminal intestinal administration of oxygenated perfluorocarbon, during experimental acute intestinal ischemia, on the acid-base blood status and the cardiopulmonary parameters.

Methods: Thirty-six rabbits were separated into three groups: (a) Control group (ischemia alone), (b) PFC-O2 group (ischemia plus infusion of oxygenated F-Decalin in intraluminal intestinal administration), and (c) PFC group (ischemia plus infusion of nonoxygenated F-Decalin in intraluminal intestinal administration). An equal number of the animals was then subjected to 8 h of intestinal ischemia by ligation of the superior mesenteric artery (subgroups 1), the mesenteric vein (subgroups 2) or both vessels (subgroups 3).

Idiopathic hypertrophic pyloric stenosis combined with left paraduodenal hernia in an adult.

Objective: We report a case of primary hypertrophic pyloric stenosis combined with a paraduodenal hernia in a 35-year-old woman.

Clinical Presentation And Intervention: The patient presented with signs of obstructive ileus. CT of the abdomen revealed a marked dilatation of the stomach and the proximal jejunum as well as a circumferential thickening of the antral-pyloric region with characteristics indicating hypertrophic pyloric stenosis.

Pancreatitis complicating mucin-hypersecreting common bile duct adenoma.

Villous adenomas of the bile ducts are extremely uncommon. We describe a 58-year-old man presenting with clinical signs and laboratory findings of acute pancreatitis and obstructive jaundice. Preoperative investigation demonstrated a dilated papillary orifice with mucus exiting (fish-mouth sign) and a filling defect in the distal common bile duct.

A rare form of isolated mesenteric Castleman's disease presenting as an abdominal mass (isolated mesenteric Castleman's disease).

Castleman's disease is a rare disorder characterized by proliferation of the lymphoid tissue. The most frequent location of the disease is the mediastinum. The location of the disease in the mesentery is rare and it is usually associated with the generalized form of the disease.

Influence of bispectral index monitoring on decision making during cardiac anesthesia.

Study Objective: To assess bispectral index (BIS) monitoring on decision making during cardiac surgery with cardiopulmonary bypass (CPB) by measuring the number of preset standardized comments with and without knowing the BIS value and by classifying the interventions following the BIS data.

Design: Prospective, randomized study.

Setting: University Hospital.

Treatment of a duodenal perforation secondary to an endoscopic sphincterotomy with clips.

Perforation is one of the most serious complications of endoscopic sphincterotomy (ES) necessitating immediate surgical intervention. We present a case of successful management of such a complication with endoclipping. A 85-year-old woman developed duodenal perforation after ES.

Endoscopic treatment and follow-up of gastrointestinal Dieulafoy's lesions.

Aim: To investigate retrospectively the clinical and endoscopic features of bleeding Dieulafoy's lesions and to assess the short- and long-term effectiveness of endoscopic treatment.

Methods: Twenty-three patients who had gastrointestinal bleeding from Dieulafoy's lesions underwent endoscopic therapy. Demographic data, mode of presentation, risk factors for gastrointestinal bleeding, blood transfusion requirements, endoscopic findings, details of endoscopic therapy, recurrence of bleeding and mortality rates were collected and analyzed retrospectively.

Long-term results of pneumatic dilation for achalasia: a 15 years' experience.

Aim: Although most patients with achalasia respond to pneumatic dilation, one-third experienced recurrence, and prolonged follow-up studies on parameters associated with various outcomes are scanty. In this retrospective study, we reported a 15-years' experience with pneumatic dilation treatment in patients with primary achalasia, and determined whether previously described predictors of outcome remain significant after endoscopic dilation.

Methods: Between September 1989 and September 2004, 39 consecutive patients with primary symptomatic achalasia (diagnosed by clinical presentation, esophagoscopy, barium esophagogram, and manometry) who received balloon dilation were followed up at regular intervals in person or by phone interview.

A variant of the double gallbladder. A possible cause of cholelithiasis?

Congenital duplication of the gallbladder is a rare anatomical malformation, which is usually discovered as an incidental finding during cholecystectomy. We report a case of a double gallbladder in a 45-year-old woman, which was discovered during laparoscopic cholecystectomy for symptomatic cholelithiasis. As it was not possible to identify the anatomical structures safely, the procedure was converted to open cholecystectomy.

Topical 0.5% nifedipine vs. lateral internal sphincterotomy for the treatment of chronic anal fissure: long-term follow-up.

Background: The aim of this study was to compare the efficacy of the local application of 0.5% nifedipine ointment vs. lateral internal sphincterotomy in the healing of chronic anal fissure.
