The desmoplastic growth pattern is associated with second-stage completion and longer survival in 2-stage hepatectomy for colorectal cancer liver metastases.

Background: Two-stage hepatectomy for bilobar colorectal cancer liver metastases is potentially curative for selected patients. Histological growth patterns of colorectal liver metastases (desmoplastic, replacement, and pushing) have prognostic value. Our aim was to evaluate their association with pathologic response to preoperative treatment, second-stage hepatectomy completion, and survival in patients treated with a curative-intent 2-stage hepatectomy.

The lymphatic system and sentinel lymph nodes: conduit for cancer metastasis.

The lymphatic system is a complicated system consisting of the lymphatic vessels and lymph nodes draining the extracellular fluid containing cellular debris, excess water and toxins to the circulatory system. The lymph nodes serve as a filter, thus, when the lymph fluid returns to the heart, it is completely sterile. In addition, the lymphatic system includes the mucosa-associated lymphoid tissue, such as tonsils, adenoids, Peyers patches in the small bowel and even the appendix.

Complete pathologic response after two-stage cytoreductive surgery with HIPEC for bulky pseudomyxoma peritonei: proof of concept.

Pseudomyxoma peritonei (PMP) is a rare disease characterized by the progressive accumulation of mucinous ascites and peritoneal implants. The optimal treatment for PMP includes the association of complete cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC). For patients with a large burdensome disease, the completeness of cytoreduction sometimes requires maximal effort surgery.

Two-stage hepatectomy for colorectal liver metastases: Pathologic response to preoperative chemotherapy is associated with second-stage completion and longer survival.

Background: Two-stage hepatectomy of bilobar colorectal liver metastases is widely used and shows encouraging survival results. However, the risk of dropout after the first stage remains high and is associated with poor survival. The objective of our study was to evaluate the factors associated with long-term survival based on the pathologic response to preoperative systemic chemotherapy in colorectal liver metastases patients who underwent two-stage hepatectomy.

Preoperative intraperitoneal oxaliplatin for unresectable peritoneal carcinomatosis of colorectal origin: a pilot study.

Background: Peritoneal carcinomatosis in colorectal cancer is an advanced stage of the disease where improved survival can be attained whenever the resection associated with hyperthermic intreperitoneal chemotherapy is possible. In unresectable cases, systemic chemotherapy is administered to obtain conversion to resectability but results have not yet been clearly evaluated. Local chemotherapy in this setting has been proven useful in several similar situations.

The best surgical approach for left colectomy: a comparative study between transverse laparotomy, midline laparotomy and laparoscopy.

Aim: To compare the early and late complications after left colectomy (LC) by left transverse laparotomy (LTL), midline laparotomy (ML) and laparoscopy (La).

Methods: From 1998 to 2003, 328 patients underwent an LC by LTL, ML or La. After matching patients for age, ASA score and indication, 159 patients were divided into three groups of 53 patients each according to the surgical approach performed.

Laparoscopic ventral rectopexy for the treatment of outlet obstruction associated with recto-anal intussusception and rectocele: a valid alternative to STARR procedure in patients with anal sphincter weakness.

Objective: This study was designed to assess the safety and outcomes achieved with Stapled Trans-Anal Rectal Resection (STARR) vs laparoscopic ventral rectopexy (LVR) in obstructed defecation patients.

Method: From 2002 to 2011, 52 patients (females) had a rectocele with outlet obstruction. After clinical assessment by an Obstructed Defecation Syndrome score (ODS), an anorectal manometry, a defecography and an endoanal ultrasound, the patients underwent either a STARR (n=25) or a LVR (n=27) according to the existence of an asymptomatic anal sphincter injury.
