The pathologist is forced to do an exhaustive study, looking for inadvertent perforations that can change the good prognosis of mucocele. We recommend follow-up of all patients with mucoceles, because sometimes they are associated with colorectal neoplasms and recurrence as pseudomyxoma peritonei.

Background: paraesophageal hiatal hernia represents 5-10% of hiatal hernias. Its importance is based on the severe complications it may have, including gastric volvulus, and surgical treatment is recommended when a diagnosis is established. Material and methods: a retrospective study of all patients who underwent surgery for paresophageal hernia between 1985 and 2007. Results: we studied 90 cases, 68 females and 22 males with a median age of 67.6 years (37-96). Forty-five patients reported pyrosis, 34 epigastric postprandial pain, and 15 dysphagia; eight patients were diagnosed with gastric volvulus. Eighty-one patients underwent elective surgery and 9 emergency surgery. Forty-seven cases underwent an open procedure and 43 a laparoscopic one; 5 (11.6%) of them required conversion. The techniques performed were D´Or fundoplication in 35 cases, Nissen in 35, Toupet in 14, simple hiatal closure in 2, Narbona in 1, and Lortat-Jakob in 1; in 10 patients a mesh was placed. The complication rate for open procedure was 10.6 and 9.5% for the laparoscopic one (p > 0.05). Median hospital stay was 9.1 days for the open procedure and 3.4 for the laparoscopic one (p < 0.05). As follow-up, we analyzed 84 patients. After a median follow-up of 12 years (1-19), 15 patients were still symptomatic (17.8%), with recurrence in 8 cases (5 required reoperation). The satisfaction rate was 95.5% Conclusion: equivalent results were observed after laparoscopic and open surgery and a significant shorter hospital stay in the laparoscopic one. Therefore, we think that laparoscopic surgery should be considered as the election procedure for paraesophageal hiatal hernia.

Carcinoid tumours are neuroendocrine neoplasms that can appear in every location of the digestive tract. They are low aggressive tumours, although they often produce local invasion and hepatic metastases, whose resection allows long-term survival. We report a case of a 64-year-old man with ileal carcinoid tumour, that underwent ileal resection and metastasectomy of one lesion in liver segment II. Surgical findings indicated peritoneal carcinomatosis. Carcinoid dissemination as peritoneal carcinomatosis has been rarely described in the literature. Cytoreductive surgery, always when complete resection is aimed, achieves asymptomatic long-term survivals.

There is no consensus on the best treatment for pseudomyxoma peritonei. We recommend avoiding incomplete surgical resections in non-reference centres and submitting patients to a reference centre to undergo adequate treatment.
