Customized femoral vein grafts for inferior vena cava reconstruction.

After extended en-bloc resection of a retroperitoneal neoplasm, prosthetic grafts can efficiently replace the inferior vena cava. However, in cases of concomitant biliary or bowel surgery, there is a risk of infection, and autogenous materials typically used present with size match. We present a method of autogenous graft construction using the femoral vein for replacement of the inferior vena cava, with an alternate configuration for renal vein implantation.

Short-term perioperative outcomes after robot-assisted and laparoscopic distal pancreatectomy.

Robotic surgery offers potential technical advantages that may facilitate pancreatic resection. The aim of this study was to evaluate the learning curve and short-term perioperative outcomes in patients who underwent laparoscopic and robot-assisted distal pancreatectomy. All perioperative variables were evaluated and compared retrospectively between laparoscopic (LDP) (n = 23) and robot-assisted (RDP) (n = 11) distal pancreatectomy. The mean total operative time was shorter in LDP (194 vs. 225 min; p = 0.017). All other perioperative criteria were similar between LDP and RDP patients (blood loss, transfusion rate, conversion, pancreatic fistula, postoperative morbidity, and duration of hospitalization). Non-adjusted CUSUM curve for composite events including operative time, conversion, postoperative morbidity and reoperation rates showed that the RDP learning curve corresponded to the first seven consecutive patients. During early experience, RDP was associated with longer operative time but similar short-term perioperative outcomes compared to conventional distal pancreatectomy.

Perioperative outcomes after totally robotic gastric bypass: a prospective nonrandomized controlled study.

BACKGROUND: Perioperative short-term outcomes could be improved after totally robotic Roux-en-Y gastric bypass (TR-RYGBP) compared with conventional laparoscopic gastric bypass. METHODS: This is a nonrandomized controlled prospective study (N = 200) to evaluate perioperative short-term outcomes. The primary endpoint was to investigate risk factors for 30-day surgical complications. RESULTS: Mean total operative time was shorter in patients who underwent TR-RYGBP (130 vs 147 minutes; P < .0001). However, postoperative surgical complications rate (13% vs 1%; P = .001), and mean overall hospital stay (9.3 vs 6.7 days; P < .0001) were higher after TR-RYGBP. By multivariate analysis, robotic surgery (hazard ratio [HR] = 15.1; 95% confidence interval [CI], 2.8 to 280; P = .01), and conversion to laparotomy (HR = 18.8; 95% CI, 1.7 to 250.8; P = .014) were independent risk factors for 30-day surgical complications. CONCLUSIONS: Although robotic gastric bypass reduces mean operative time, TR-RYGBP is associated with an increased postoperative surgical complications rate and longer hospitalization.

Ascites and malnutrition are predictive factors for incomplete cytoreductive surgery for peritoneal carcinomatosis from gastric cancer.

BACKGROUND: Prognosis in peritoneal carcinomatosis from gastric cancer has improved with cytoreductive surgery (CS) and hyperthermic intraperitoneal chemotherapy. The aim of this study was to identify predictive factors for incomplete CS. METHODS: Forty-five patients undergoing laparotomy for gastric cancer with peritoneal carcinomatosis were prospectively included from January 2000 to December 2010. In case of optimal CS, patients (n = 14) received hyperthermic intraperitoneal chemotherapy. Otherwise, the laparotomy was closed or a palliative procedure was performed if necessary. All preoperative data were compared between the 2 groups. RESULTS: Ascites (hazard ratio, .09; 95% confidence interval, .010-.48; P = .0103) and nutritional status evaluated by the prognostic nutrition index (hazard ratio, .11; 95% confidence interval, .0019-.54; P = .027) were independent predictive factors for incomplete CS. CONCLUSIONS: The selection of patients for CS plus hyperthermic intraperitoneal chemotherapy should include the assessment of nutritional status and the detection of an ascites.

Post-traumatic transdiaphragmatic intercostal hernia: report of two cases.

Transdiaphragmatic intercostal hernias (TIH) are rare. Less than 40 cases of TIH have so far been reported, with only 8 cases involving herniation of the liver. This report presents the case of 2 patients with a right-sided abdominal lump following a fall. Thoracoabdominal CT-scan showed a TIH between the 9th and 10th ribs with liver and right colonic herniation in both patients. Both patients were successfully treated with mesh repair. The presentation, physiopathology and management of this rare occurrence are discussed.

Small bowel involvement is a prognostic factor in colorectal carcinomatosis treated with complete cytoreductive surgery plus hyperthermic intraperitoneal chemotherapy.

BACKGROUND: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) is a promising treatment for patients with peritoneal carcinomatosis (PC). Our objective was to identify new prognostic factors in patients with PC from colorectal cancer treated with this procedure. METHODS: All patients with PC from colorectal cancer treated by HIPEC from January 2000 to December 2007 were prospectively included. The tumor extension was assessed by the Peritoneal Cancer Index (PCI) and the residual disease was recorded using the completeness cytoreductive score (CCs). All clinical and treatment data were computed in univariate and multivariable analyses using survival as primary end point. RESULTS: We carried out 51 complete procedures in 49 consecutive patients. The mean PCI was 10. The allocation of CCs was: CC-0 = 37, CC-1 = 14. The five-year overall and progression-free survival rate were 40% and 20%, respectively. Several prognostic factors for survival were identified by univariate analysis: PCI < 9 (P < 0.001), CC-0 vs. CC-1 (P < 0.01) and involvement of area 4 (P = 0.06), area 5 (P = 0.031), area 7 (P = 0.014), area 8 (P = 0.022), area 10 (P < 0.0001), and area 11 (P = 0.02). Only the involvement of the distal jejunum (area 10) was significant in the multivariable analysis (P = 0.027). CONCLUSIONS: We demonstrated that the involvement of area 10 (distal jejunum of the PCI score) was an independent factor associated with poor prognosis.

Additional colectomy after colonoscopic polypectomy for T1 colon cancer: a fine balance between oncologic benefit and operative risk.

PURPOSE: The treatment of early-stage colorectal cancers removed endoscopically depends on histopathologic findings. This study aimed to assess the benefit-risk balance for patients who underwent additional surgery after endoscopic resection of a T1 carcinoma with unfavorable histology. METHODS: From 2000 to 2010, 64 consecutive patients were included in this retrospective study. Specimens resected after endoscopic polypectomy showed at least one of the following unfavorable factors: no free margin, lymphovascular invasion, poorly differentiated grade, SM2-3 involvement (submucosal invasion greater than 300 µm from the muscularis mucosae), tumor budding, sessile morphology, and piecemeal resection. The main objective was to assess the benefit-risk balance of an oncological resection performed after the polypectomy. Oncological benefit was measured by the lymph node metastasis rate and the persistence of a residual adenocarcinoma on the specimen. The risk was measured by the occurrence of severe complications of grade III-IV or death. The associations between these end points and clinicopathologic variables were evaluated by univariate analysis and logistic regression. RESULTS: Five patients (7.8 %) had lymph node metastases and two (3.1 %) had residual carcinomas. Eight patients (12.5 %) had grade III-IV morbidity. There were no deaths. Oncological benefit was associated by logistic regression analysis with patients who presented multiple criteria (≥2) that led to surgery (p = 0.031). The benefit-risk balance was favorable only for those patients. CONCLUSIONS: Additional surgery is required for patients who present multiple adverse histological criteria. If only one criterion is selected, the indication should be discussed, especially for patients with multiple comorbidities.

Multifilament polypropylene mesh for urinary incontinence: 10 cases of infections requiring removal of the sling.

One hundred and forty-nine women received a suburethral woven polypropylene mesh insertion for urodynamic stress incontinence. Eleven patients (7.5%) presented between 4 and 17 months after surgery (mean 10 months) with symptoms of retropubic infection. Ten patients required surgical exploration, drainage of the collection and removal of the tape either unilaterally (six) or bilaterally (four). Bacterial cultures were negative in nine women. Following removal of the tape, eight patients reported residual incontinence, either stress leakage (five) or de novo urge incontinence (three). Multifilament polypropylene meshes appear to be more at risk of infection, usually requiring sling removal, which may be related to pore size of the mesh. Our data reinforce the importance of proper evaluation of new surgical procedures by rigorously designed randomised trials with adequate follow up to identify rare but potentially serious complications.

Long-term results of transperitoneal laparoscopic fenestration in the treatment of simple renal cysts.

The aim of this paper was to assess long-term results of transperitoneal laparoscopic fenestration in the treatment of symptomatic simple renal cysts. Fifteen consecutive patients (7 men, 8 women), with a mean age of 51 years (range, 36-79 years), underwent transperitoneal fenestration of simple renal cysts (SRC) at our institution from 1994 to 2001. Data were collected by reviewing patients' clinical files, conducting telephone interviews regarding symptoms, and followup renal ultrasonography (US). There were 15 symptomatic cysts (10 parenchymal, 5 peripelvic) ranging in diameter from 3.5 to 20 cm (mean, 8 cm). All patients had lumbar pain and in four (26.6%) the collecting system was compressed by the cysts. Fenestration was carried out laparoscopically in all patients. There was no mortality and no postoperative complications were recorded. No malignancies were detected at final histopathology. Mean length of stay was 2.5 days. All patients were available for long-term followup. At a mean of 60 months (range, 22-93 months) from surgery, three patients (20%) complained of slight discomfort in the lumbar area not requiring any analgesic. No recurrence of the cysts was seen on US. Two asymptomatic patients (13.3%) developed additional cysts originating from sites different than the one operated on. Laparoscopic fenestration of SRC is safe and effective in the long term to relieve patients from symptoms.
