Neither P/L nor N/L ratios were associated with survival after rectal cancer surgery. Further studies on large series might provide insights on the role of these inexpensive blood biomarkers in rectal cancer.

Surgical morbidity rate was not affected by age. Cardiovascular and pulmonary comorbid conditions were mainly responsible for the higher morbidity rate reported in the elderly patients, although advanced age, per se, should not be considered a contraindication to laparoscopic colorectal surgery for cancer.

Short-term results after laparoscopic colorectal surgery for cancer in patients ≥75 years old reveal that they have higher postoperative risk compared to their younger counterparts, even when matched by ASA score and type of operation. It suggests that although advanced age, per se, is not a contraindication, it is a risk for patients who undergo laparoscopic colorectal surgery for cancer. This surgery in elderly patients should be performed by experienced surgeons in specialized centers to keep postoperative risk to a minimum.

Pancreatitis may be associated with thoracic complications, notably chronic massive pleural effusion (CMPE) and, rarely, pseudocysts with mediastinal extension (PME) and enzymatic mediastinitis (EM). Our personal experience with 14 cases of thoracic complications (nine CMPE, two PME associated with pleural effusion, and three EM of 670 patients who underwent surgery; of these, 191 had acute and 479 had chronic pancreatitis) during 16 years (1970-1986) is reported. In the patients with CMPE, the initial symptoms were progressive dyspnea eventually associated with cough and chest pain. In the PME cases, there was dysphagia associated with left subscapular pain and left chest pain. The initial signs in the patients with EM were sudden dyspnea, cyanosis, retrosternal pain, tachycardia, and acute heart failure. A fistula between the pancreatic ductal system and the pleural cavity in seven of the nine patients with CMPE was demonstrated by intraoperative pancreatography and/ or cystography. On the contrary, preoperative endoscopic pancreatography demonstrated the sinus tract in only three of the seven. In both cases of PME, computed tomography (CT) provided a correct diagnosis that was confirmed at surgery. In the patients with EM, the diagnosis was suggested by the clinical appearance and was confirmed by the chest roentgenogram and by CT. All patients had operations after varying periods of unsuccessful 2-4-week-long conservative treatment. One patient with infected ascites died postoperatively. There were no thoracic recurrences of pancreatic disease among the other patients at a 10-month-10-year follow-up observation after surgery.

Spontaneous rupture of gastrointestinal stromal tumor (GIST) with hemoperitoneum is an extremely rare clinical presentation of this mesenchymal tumor. We report the unusual case of a 68-year-old man who was admitted to the hospital with abdominal pain. While waiting for the results of his laboratory tests the patient became pale and tachycardic and his abdomen distended with generalized rebound tenderness. A CT scan suggested rupture of a cavernous angioma of the liver and the patient was brought to the operating room for an explorative laparoscopy, which revealed hemoperitoneum from a ruptured giant gastric GIST. After conversion to laparotomy, the tumor was excised: it was 11 x 10 x 5 cm in size, with massive necrosis and clotted blood inside. Immunohistochemical examination revealed reactivity to c-KIT and CD34, consistent with the diagnostic criteria for GIST, with low mitotic activity (< 5/50 HPF). The postoperative course was uneventful, and the clinical and radiological follow-up at 6 months is negative for recurrence.
