SYSTEMIZATION OF LAPAROSCOPIC INGUINAL HERNIA REPAIR (TAPP) BASED ON A NEW ANATOMICAL CONCEPT: INVERTED Y AND FIVE TRIANGLES.

Background: Laparoscopic inguinal hernia repair has been shown to be superior than open repairs with faster return to daily activities and decrease in the occurrence of chronic pain. However, higher direct costs and mandatory use of general anesthesia are arguments against their use. In addition, increased complexity of surgery resulting from an anatomy that is unusual to general surgeons prevents the widespread adoption of laparoscopic approach.

Outcome of pigs with short gut syndrome submitted to orthotopic intestinal transplantation.

Purpose: To evaluate the current model of small bowel resection and intestinal transplantation in pigs.

Methods: Forty two Large White pigs were distributed in five groups: G1(n=6), G2(n=6) and G3(n=6) were submitted to 80%,100% and 100% plus right colon resection respectively and G4(n=7) and G5(n=5) to 100% SBR plus IT without and with immunosuppression based on Tacrolimus and Mycophenolic acid. Evaluation included weight control, clinical status, biochemical analysis and endoscopies for graft biopsies.

Evaluation of nutritional indicators and body composition in patients with advanced liver disease enrolled for liver transplantation.

Purpose: Malnutrition is prevalent in patients with advanced liver disease (LD) related to multifactorial causes. Fluid retention can underestimate the nutritional status based on anthropometric measures. We evaluated nutritional indicators and body composition (BC) in patients with liver cirrhosis and correlated them with LD severity.

Meningeal tumor: A rare extrahepatic association in patients with polycystic liver disease enrolled for liver transplantation.

In the present study, we described a rare association of polycystic liver disease (PCLD) with intracranial meningiomas in patients included on a liver transplant list, focusing on the diagnosis, treatment and possible association with any genetic alterations. Two female patients, aged 39 and 49 years were included on a liver transplant list due to extensive PCLD, with symptoms related to an abdominal compartmental syndrome. Screening for extrahepatic manifestation revealed a right frontal meningioma in the first patient, and a parietal posterior calcified meningioma in the second patient, measuring 1 and 7×3×2 cm in diameter, respectively.

Peritoneal pseudomyxoma associated with synchronic malignant mucinous neoplasias of the cecum, appendix and rectum. Case report and review of the literature.

Peritoneal pseudomyxoma is a pathological condition that compromises the peritoneum, characterized by the production of large quantities of mucinous liquid, which progressively fills the peritoneal cavity, originating in general from mucinous appendicular or ovarian tumors. We report a peritoneal pseudomyxoma associated with mucinous adenocarcinoma of the appendix synchronic with adenocarcinoma of the rectum in a 44 year old patient, where the initial diagnosis was rectal adenocarcinoma. Tumour of the appendix and peritoneal pseudomyxoma were incidental and found intraoperatively.

[Outpatient surgery for anorectal diseases: the experience of the Clinics Hospital of the Medical School, Botucatu, SP, Brazil, in 437 cases].

Background: The number of outpatient surgical procedures performed in hospitals, as well as in private clinics, increases daily. In some countries, such as France, outpatient operations outnumber inpatient operations.

Objective: To evaluate results obtained at the Surgical Outpatient Clinic of the Clinics Hospital of the Medical School, Botucatu, SP, Brazil.
