McKittrick-Wheelock syndrome treated by laparoscopy: report of 3 cases.

Aim: To present 3 cases of secreting villous adenoma (McKittrick-Wheelock syndrome) successfully treated with laparoscopic surgery.

Cases: We present 3 cases, characterized by chronic diarrhea and requiring hospitalization owing to electrolyte and fluid depletion with acute renal failure. Owing to the extension and location of the adenomas, laparoscopic surgery (low anterior resection or procto-sigmoidectomy resection) was performed after medical treatment and endoscopic diagnosis.

Management of anastomotic leaks after laparoscopic Roux-en-Y gastric bypass.

Background: Anastomotic leaks after bariatric surgery carry high morbidity and mortality. We aimed to describe our experience of the diagnosis and management of gastrointestinal anastomotic leaks in patients undergoing laparoscopic gastric bypass in a single institution.

Methods: Of 1,200 patients who underwent laparoscopic Roux-en-Y gastric bypass with manual gastrojejunal anastomosis for morbid obesity from January 2002 to January 2007, we retrospectively analyzed 59 patients with anastomotic leak.

Can we predict immediate outcome after laparoscopic rectal surgery? Multivariate analysis of clinical, anatomic, and pathologic features after 3-dimensional reconstruction of the pelvic anatomy.

Objectives: The laparoscopic approach for colon resection is widely accepted but its definitive role in rectal tumors is controversial due to the technical difficulties associated with this procedure. Tumor size and volume, and pelvic dimensions may influence intraoperative and/or immediate outcome. This study aimed to evaluate the predictive value of anatomic and pathologic features on immediate outcome after laparoscopic rectal resection.

Can we predict immediate outcome after laparoscopic splenectomy for splenomegaly? Multivariate analysis of clinical, anatomic, and pathologic features after 3D reconstruction of the spleen.

The laparoscopic approach is the treatment of choice for splenectomy, but its definitive role in splenomegaly is controversial. Factors that influence immediate outcome are clinical, anatomic, and pathological. The aim of this study was to evaluate the predictive factors on outcome after laparoscopic splenectomy in splenomegaly.

Mucinous cystadenocarcinoma of the pancreas diagnosed in postpartum.

Background: Cystic tumors of the pancreas are uncommon. They account for 10-15% of all pancreatic cystic masses and only 1% of pancreatic malignancies. Mucinous cystadenocarcinoma is the most frequent pancreatic cystadenocarcinoma and it is mainly seen in women, suggesting a sex hormone influence.

Unusual upper gastrointestinal diseases associated with achalasia: laparoscopic approach.

Background: As a result of the high success rate associated with the laparoscopic approach for achalasia, surgery for the disease has become the treatment of choice in recent years. With the greater number of patients undergoing surgery, surgeons may encounter other upper gastroesophageal illnesses associated with achalasia, and these may require evaluation for simultaneous surgical treatment. This study aimed to evaluate the incidence of gastroesophageal diseases associated with achalasia, and to determine the possibility for simultaneous management using the laparoscopic approach.

Laparoscopic resection of clinically suspected gastric stromal tumors.

Gastrointestinal stromal tumors (GISTs) account for 5% of all gastric tumors. Preoperative diagnosis is relatively difficult because biopsy samples are rarely obtained during fibergastroscopy. Surgical radical resection is the gold standard treatment, allowing pathologic study for both diagnosis and prognosis.
