Short-term outcome after laparoscopic or open restorative mesorectal excision for rectal cancer: a comparative cohort study.

PURPOSE: The laparoscopic approach to rectal cancer is still a controversial procedure. A comparative cohort study was conducted to assess short-term results of laparoscopic restorative mesorectal excision. METHODS: From January 1998 to December 2000, laparotomy was performed on all primary rectal cancer undergoing radical excision. From January 2002 to September 2004, all cases about to undergo radical excision were considered for laparoscopy. Patients with fixed tumor or T4, indications for synchronous hepatectomy, emergencies, and medical contraindications were not included. The study was based on the intention-to-treat principle. RESULTS: Short-term outcome was compared between the laparoscopy group (n=104) and the laparotomy group (n=68). Demographic, general and tumor data, and rates of preoperative irradiation were comparable, as were surgical procedures and perioperative management. Hospital mortality (1 and 2.9 percent, P=0.33) and three-month overall morbidity (43.3 and 48.5 percent, P=0.49) were comparable between laparoscopy and laparotomy groups. Surgical complication rates were comparable (39.3 and 35.5 percent, P=0.58), but a significantly lower medical complication rate was observed in laparoscopy patients (8.7 and 20.6 percent, P=0.025), mainly because this group had fewer respiratory complications. Hospital stay was shorter in laparoscopy patients (10 and 14 days, P<0.001). Oncologic quality criteria were comparable, in terms of number of lymph nodes, lateral and distal margins, and delivery of postoperative chemotherapy. CONCLUSIONS: The laparoscopic approach to restorative mesorectal excision for cancer does not increase postoperative morbidity or reduce oncologic quality. Our results suggest that the short-term outcome is probably improved with this procedure.

Perineal small bowel fistula after pelvic exenteration for cancer: technical guidelines for perineal fistula.

BACKGROUND: To determine guidelines for the management of perineal small bowel fistula (PSF) after total or posterior pelvic exenteration. METHODS: During 15 years, 315 curative pelvic exenterations were performed. PSF occurred in 15 patients (3.5%). We retrieved the precise modality of radiotherapy (fields and doses) and management of all patients (type of surgery, number of surgery and mortality). Delay of occurrence was divided in early (within 30 days or before hospital discharge) and delayed. RESULTS: All patients underwent surgery. Mortality rate was 13%. Fourteen patients (93%) had history of radiotherapy. No PSF was noted after anterior pelvic exenteration. Higher frequency of PSF was noted after total pelvic exenteration versus posterior pelvic exenteration (P = 0.04). Early PSF occurred in four patients (27%) with higher frequency of small bowel intraoperative injury. Late PSF occurred in 11 patients (73%) divided in small bowel injury in contact with pelvic staples (n = 4) and disease recurrence (n = 6, local recurrence or carcinomatosis). One patient had delayed PSF by ulceration of small bowel in contact with pelvic drain. CONCLUSION: PSF was a life-threatening complication of pelvic exenteration. Radiotherapy leads to weaken small bowel with difficulty of cicatrisation. During pelvic exenteration: (a) extreme careful dissection and interposition of great omentum could avoid small bowel injury, (b) control of pelvic vessels and closure of rectum remnant should not used staplers. Intraoperative management of PSF used successful simple repair in case of early PSF or segmentary resection indeed enlarged to right colon in case of delayed PSF. Postoperative courses had to use intravenous hyperalimentation and digestive tract discharge.

Hemorrhage after duodenopancreatectomy: impact of neoadjuvant radiochemotherapy and experience with sentinel bleeding.

Postoperative hemorrhage (PH) after duodenopancreatectomy (DP) is frequently lethal. The aim of this study was to delineate guidelines of management. Between August 1994 and July 2003, 172 patients underwent DP for cancer. Altogether, 26 patients were subjected to an institutional protocol (IP) with standard-dose chemoradiation (CRT) and 4 patients to an extrainstitutional protocol (EIP) with high-dose CRT. Sixteen patients (9.3%) were reoperated for PH. Hemorrhage occurred in 23% of irradiated patients (4 EIP, 3 IP) and in 6% of nonirradiated patients [confidence interval (CI) 1.8-6.5]. Pancreatic leak occurred in nine patients with PH (56%). Sentinel bleeding (SB) was noted in eight patients (50%) with a mean delay of 10 days after DP. Overall mortality after hemorrhage was 56%. Morality rates of patients with EIP or IP were, respectively, 100% and 0%. Mortality rates of patients with or without SB were similar. Mortality rates of axial bleeding (hepatic artery, mesenteric vessels) or lateral bleeding (pancreas remnant, splenic vessels) were, respectively, 88% and 25% (CI 1.6-8.6). Completion of pancreatectomy was achieved in 75% without rebleeding. Preoperative high-dose CRT increased the risk of fatal PH. Because SB occurs before massive hemorrhage, prompt reoperation could reduce mortality. Completion of pancreatectomy was essential during reintervention. Axial bleeding supports high mortality. Moving to the left, the pancreatojejunostomy could avoid contact of pancreatic juice with axial vessels in the case of pancreatic leakage. Ligating the gastroduodenal artery during DP had to leave a stump of around 1 cm to facilitate hemorrhage control without ligating the common hepatic artery.

Assessment of pathologic response after preoperative chemoradiotherapy and surgery in pancreatic adenocarcinoma.

PURPOSE: The benefits provided by preoperative chemoradiotherapy (CRT) in pancreatic ductular adenocarcinoma (PDA) are still controversial. However, in most reports from referral centers, improvement in local control and survival appears to be provided in selected patients. The aim of this retrospective study was to analyze the radiation-induced pathologic effects of preoperative CRT in patients with resectable PDA and determine the precise long-term outcome of the responding patients. METHODS AND MATERIALS: Between November 1996 and October 2003, 61 patients underwent preoperative CRT for resectable PDA. The tumor location was the pancreatic head in 49 patients and pancreatic body in 12 patients. Of the 61 patients, 21 (34.5%) did not undergo surgery because of disease progression and 40 (65.5%) underwent pancreatic resection, including pancreaticoduodenectomy in 32 (80%) and distal pancreatectomy in 8 (20%). RESULTS: A major pathologic response was noted in 9 patients, including three complete responses, and was found only in patients with tumor of the pancreatic head. The local control rate was similar in patients with and without a major pathologic response. Survival in patients with a major response was significantly greater than in those without a response or with a minor response. CONCLUSION: Major tumor downstaging can be provided by preoperative CRT in patients with resectable cephalic PDA. Survival appears to be significantly improved in selected patients.

Preoperative locoregional re-evaluation by endoscopic ultrasound in pancreatic ductal adenocarcinoma after neoadjuvant chemoradiation.

INTRODUCTION: The accuracy of endoscopic ultrasound (EUS) for the diagnosis and staging of pancreatic ductal adenocarcinoma (PDA) has been confirmed. Chemo-radiotherpay (CRT) induces tumor changes which can limit the accuracy of EUS. The aim of our study was to analyze the efficacy of EUS following neoadjuvant CRT comparing findings with the pathology results. PATIENTS AND METHODS: From November 1996 to October 2003, 45 patients with histologically proven and EUS-staged PDA were treated with neo-adjuvant CRT and radical surgery. All were restaged before surgery using both EUS and computed tomography. Fifteen patients were found to have developed distant metastases. Thirty patients finally underwent pancreaticoduodenectomy (N=24) or distal pancreatectomy (N=6). RESULTS: Following CRT, tumor stage was correctly assessed in 12 patients (40%). The most frequent misinterpretation was overestimation of tumor size (N=13, 43.3%). Locoregional vascular invasion of veins was suspected by EUS in 13 patients (43.3%) but surgical findings and the histological examination were both negative. Node status was correctly assessed in 27 patients (90%) but nodal involvement was found on the histological specimen in only 3 patients. CONCLUSION: Preoperative EUS after neoadjuvant CRT for PDA does not enable reliable definitive selection of patients for surgery, probably due to radiation-induced pancreatic changes.

Treatment of esophagojejunostomic leakage by cervical stapling and loop jejunostomy.

Reestablishment of digestive continuity after radical surgery for severe esophagojejunostomic leakage is a major challenge associated with high morbidity and uncertain feasibility. In this case report we describe a conservative double exclusion technique involving cervical stapling and loop jejunostomy. This technique greatly simplifies subsequent reconstruction and is suitable in most cases.

Preoperative systemic chemotherapy does not modify strategy of liver resection.

BACKGROUND/AIMS: Most patients who undergo surgical resection of colorectal liver metastases have been previously treated with chemotherapy as adjuvant therapy or as a primary treatment. The aim of this retrospective study was to compare morbidity, mortality, liver function and histology of the liver specimens in patients undergoing colorectal liver metastases (CRLM) resection with and without a history of previous chemotherapy. METHODOLOGY: Records of 210 patients who underwent CRLM resection in our institution between January 1996 and March 2003 were retrospectively reviewed. We selected for further analysis medical charts of 40 patients who didn't receive a combined treatment concurrently to liver resection. Group I included 25 patients who did not receive adjuvant chemotherapy. Group II included 15 patients who received chemotherapy in the 3 months before liver resection. RESULTS: Postoperative mortality was 0% and 0.7% in group I and II respectively. Specific liver complications and pulmonary complications were similar in the two groups: 20% and 32% us. 33% respectively. The mean length of stay in the hospital was similar in the two groups (19 +/- 14 vs. 14 +/- 8). Changes of liver function test were similar in the two groups. Pathologic examination of liver specimens was not different in the two groups. CONCLUSIONS: Preoperative systemic chemotherapy didn't increase the risk of liver resection.
