ObjectiveTo review and update the authors' experience with resectional surgery for proximal bile duct carcinoma (Klatskin tumor) and assess the role of liver resection over the past 25 years.

The presence of whole identifiable cells carried in the pneumoperitoneum raises concerns for operating staff and could be a mechanism for tumour implantation. No malignant cells were found, but ethical considerations prevented intentional coagulation of malignant tissue.

The classic treatment of generalized peritonitis due to perforation of sigmoid diverticula is based on the principle of a two-stage surgery with a temporary derivation of the colonic transit. This procedure is associated with a prohibitively high immediate and delayed morbidity, especially associated with the abdominal wound. The laparoscopic approach to this complication is less aggressive and allows a second-stage elective laparoscopic resection. Eighteen consecutive patients (ten women and eight men; average age, 53.7 years) underwent emergency laparoscopic treatment for generalized peritonitis due to perforated diverticula. Eight of these patients had previously had diverticulitis attacks. By peritoneal cavity exploration and full peritoneal lavage (average, 15 L), the infected sigmoid lesion was stuck with biologic glue. A drain was inserted at the site of the lesion and in some cases also in other abdominal zones. No colostomy was necessary. Antibiotic treatment was started at diagnosis and continued for a minimum of 7 days. There was no mortality. Morbidity was limited to three patients (two cases of lymphangitis and one of pulmonary disease). No patient had a wound abscess or residual deep collections. The mean hospitalization was 8 days. Fourteen patients underwent elective laparoscopic sigmoid resection with a delay of 3.5 months. One conversion to laparotomy was necessary. The laparoscopic treatment of generalized peritonitis due to perforated sigmoid diverticula is an interesting alternative to the traditional treatment. It is associated with a lower morbidity, a shorter postoperative hospital stay, and an improvement in the patient's quality of life, because colostomy is avoided. It is also associated with economic savings.

Situs inversus totalis is a rare defect which can present difficulties in the management in laparoscopic surgery due to the mirror-image anatomy. Herein, we report a patient with situs inversus totalis and super-super-obesity (BMI 76 kg/m2). We performed successful laparoscopic sleeve gastrectomy. Technical details of this operation, with situs inversus totalis, are presented. There were no major difficulties compared to patients with usual anatomy. There are potential diseases associated with situs inversus and obesity; therefore, a careful investigation, including a chest x-ray and cardiac and abdominal ultrasounds should be performed before surgery. Sleeve gastrectomy is an adequate procedure in super-super-obese patients with situs inversus totalis.
