Laparoscopic segmental left colectomy for splenic flexure carcinoma: a single institution experience.

BACKGROUND: There is ongoing debate regarding surgical treatment of splenic flexure cancer. The main points of controversy include the appropriate extent of colon resection, either to the right or to the left, and the appropriate extent of lymph-node dissection. The aim of this study was to review our experience in laparoscopic treatment of splenic flexure cancer cases and to compare our data to the recent literature. METHODS: Consecutive patients, operated on for splenic flexure colon carcinoma at a single institution between April 2005 and January 2013, were included in the study. Exclusion criteria were a previous history of colorectal cancer, recurrent colonic cancer, emergency cases with an obstructive tumor or a perforated tumor with peritonitis, synchronous cancer, palliative surgery, and a past history of colorectal resection. Patients underwent laparoscopic segmental left colectomy with ligation of the left branch of the middle colic and of the left colic artery. Patient characteristics, operative and postoperative outcomes, and long-term technical, functional, and oncological results from a prospectively maintained database were retrospectively analyzed. After hospital discharge, standardized follow-up was performed at 1 month postoperatively, then every 3 months during the first 2 years, and every 6 months thereafter, for a total of 5 years. RESULTS: A total of 28 consecutive patients (16 males) with a median age of 71.8 years (range 42.5-88.8 years) were included. Ninety-day mortality was 3.5% and surgical morbidity was 21.5% with anastomotic leak rate of 10.7%. All survivors experienced good or very good functional results. During a median follow-up period of 50.9 months, eight patients (28.5%) presented with a recurrence. The 5-year overall and disease-free survival rates were 46.3% and 39.2%, respectively. CONCLUSIONS: Segmental left colectomy for splenic flexure carcinoma is associated with reasonably low morbidity and very good functional results. However, survival rates are low.

Prospective evaluation of functional outcomes after laparoscopic sigmoidectomy with high tie of the inferior mesenteric artery for diverticular disease in consecutive male patients.

BACKGROUND: To date, there has been no consensus concerning the vascular approach during sigmoid colectomy for diverticular disease. The aim of this study was to determine the functional impact of elective laparoscopic sigmoidectomy performed with high ligation of the inferior mesenteric artery for diverticulitis in consecutive male patients. METHODS: Twenty-five consecutive patients of median age 53 years were enrolled in a prospective single-centre pilot study at a tertiary teaching hospital. Main outcome measures were functional results. Patients were asked to complete standardized, validated questionnaires to evaluate preoperative and 6 months postoperative bowel symptomatology (Jorge-Wexner Incontinence Score and KESS score), urinary function (IPSS), and sexual function (IIEF). Secondary outcomes were surgical data, morbidity, and quality of life (SF-36). RESULTS: There were no significant differences between preoperative and 6 months postoperative total scores for bowel symptomatology, urinary function, and sexual function. There were no perioperative deaths. The morbidity rate was 12% including three minor and no major events. Quality of life demonstrated statistically better general health (p < 0.01) and better medical status over the prior 4 weeks at 6 months after surgery, compared to baseline. This single-centre prospective study has a limited number of patients, relatively short follow-up time, and includes only male patients. CONCLUSION: Laparoscopic sigmoidectomy with high tie of the inferior mesenteric artery for diverticular disease does not induce functional disorders at 6 months after surgery. The benefit of the operation for quality of life is even greater for general health and medical status.

Level of inferior mesenteric artery ligation in low rectal cancer surgery: high tie preferred over low tie.

BACKGROUND: There is no demonstrated benefit of high-tie versus low-tie vascular transections in low rectal cancer surgery. The aim of this study was to compare the effects of high tie and low tie of the inferior mesenteric artery on colonic length. METHODS: This study was conducted in a surgical anatomy research laboratory. Anatomical dissections were performed on 11 human cadavers. We performed full left colonic mobilization, section of the descending-sigmoid junction, and high and low ligation of the inferior mesenteric artery. Distance from the proximal colon limb to the lower edge of the pubis symphysis was recorded after each step of vascular division. Three measurements were successively performed: before vascular section, after inferior mesenteric artery ligation, and after inferior mesenteric artery and vein section. RESULTS: Before vascular section, the mean distance between colonic end and lower edge of the symphysis pubis was - 1.9 ± 3.5 cm. After combined artery and vein section, the mean distance was + 10.7 ± 4.6 cm for high tie and + 1.5 ± 3 cm for low tie. A limitation of this study is the use of embalmed anatomical specimens, rather than live patients, and the small number of specimens. This study also does not evaluate colon limb vascularization or the impact of proximal lymph node dissection on survival rates. CONCLUSIONS: High tie of the inferior mesenteric artery at its aortic origin allows a gain of extra length of about 9 cm over low tie.

Venous leiomyosarcoma arising from the radiocephalic vein.

Vascular leiomyosarcoma is a very rare soft tissue neoplasma. We are reporting a vascular leiomyosarcoma case arising from an unusual site: the radiocephalic vein. Despite a poor prognosis, after surgery and radiotherapy, the patient was alive without signs of recurrence two years later.

Laparoscopic delayed coloanal anastomosis without diverting ileostomy for low rectal cancer surgery: 85 consecutive patients from a single institution.

BACKGROUND: Surgical treatment for low rectal cancer septic complications often requires an ileostomy for fecal diversion. Delayed coloanal anastomosis (CAA) has been performed for several years to reduce septic complications and to avoid ileostomy. The aim of this study was to report the technical, functional and oncological results of delayed CAA in patients operated on for low rectal cancer focusing on pelvic septic complications. METHODS: All consecutive patients operated on for low rectal cancer suitable for total mesorectal excision and two-step delayed CAA at a single institution between May 2000 and September 2013 were included in the study. Patients' characteristics, operative and postoperative outcomes, long-term technical, functional and oncological results from a prospectively maintained database, were retrospectively analyzed. RESULTS: A total of 85 consecutive patients (69 men), of median age 63 years (range 42-83 years) were included. Median delay between the first and the second step of the operation was 6 days (range 2-13 days). Twenty-one patients (25%) developed pelvic sepsis, nine of them (10.6%) developed an anastomotic leak. Twenty-three patients had a definitive stoma at the end of follow-up. Seventeen patients (29%) experienced a poor functional result. Thirty-three patients (38%) presented with recurrence at a median follow-up of 59 months (range 12-135 months). Seven (8.2%) developed a local recurrence, 18 a distant metastasis (21.1%) and 8 (9.4%) both a local and distant recurrence. CONCLUSIONS: In our series, laparoscopic total mesorectal excision with delayed coloanal anastomosis was associated with septic complications and oncologic results similar to those reported after total mesorectal excision with conventional anastomosis and ileostomy, nearly one-third of patients experience a poor functional result. A randomized trial comparing these two options for low rectal cancer is under way.

Early experience with ambulatory robotic ventral rectopexy.

OBJECTIVE OF THE STUDY: Ventral rectopexy can be performed robotically with only limited trauma for the patient, making its performance in an ambulatory setting potentially interesting. The aim of this study is to report our preliminary experience with ambulatory robotic ventral rectopexy in consecutive patients. PATIENTS AND METHODS: Ten consecutive patients underwent robotic ventral rectopexy for total rectal prolapse (n=8) or symptomatic enterocele (n=2) between February 2014 and April 2015. Patients were selected for outpatient treatment based on criteria of patient motivation, favorable social conditions, and satisfactory general condition. Patient characteristics, technical results and cost were reported. RESULTS: The mean operating time was 94minutes (range: 78-150). The average operating room occupancy time was 254minutes (222-339). There were no operative complications, conversion to laparotomy, or postoperative complication. The average duration of hospital stay was 11 (8-32) hours. Two patients required hospitalization: one for persistent pain and the other for urinary retention. The average maximum pain score recorded on postoperative day 1 was 2/10 on a visual analog scale (range: 0-5/10). Estimated average cost (excluding amortization of the purchase of the robot) was €9088 per procedure. CONCLUSIONS: Ambulatory management of robotic ventral rectopexy is feasible and safe.

Day case robotic ventral rectopexy compared with day case laparoscopic ventral rectopexy: a prospective study.

BACKGROUND: Ventral rectopexy to the promontory has become one of the most strongly advocated surgical treatments for patients with full-thickness rectal prolapse and deep enterocele. Despite its challenges, laparoscopic ventral rectopexy with or without robotic assistance for selected patients can be performed with relatively minimal patient trauma thus creating the potential for same-day discharge. The aim of this prospective case-controlled study was to assess the feasibility, safety, and cost of day case robotic ventral rectopexy compared with routine day case laparoscopic ventral rectopexy. METHODS: Between February 28, 2014 and March 3, 2015, 20 consecutive patients underwent day case laparoscopic ventral rectopexy for total rectal prolapse or deep enterocele at Michallon University Hospital, Grenoble. Patients were selected for day case surgery on the basis of motivation, favorable social circumstances, and general fitness. One out of every two patients underwent the robotic procedure (n = 10). Demographics, technical results, and costs were compared between both groups. RESULTS: Patients from both groups were comparable in terms of demographics and technical results. Patients operated on with the robot had significantly less pain (p = 0.045). Robotic rectopexy was associated with longer median operative time (94 vs 52.5 min, p < 0.001) and higher costs (9088 vs 3729 euros per procedure, p < 0.001) than laparoscopic rectopexy. CONCLUSIONS: Day case robotic ventral rectopexy is feasible and safe, but results in longer operative time and higher costs than classical laparoscopic ventral rectopexy for full-thickness rectal prolapse and enterocele.

Management of pancreatic trauma.

INTRODUCTION: Pancreatic trauma (PT) is associated with high morbidity and mortality; the therapeutic options remain debated. MATERIAL AND METHODS: Retrospective study of PT treated in the University Hospital of Grenoble over a 22-year span. The decision for initial laparotomy depended on hemodynamic status as well as on associated lesions. Main pancreatic duct lesions were always searched for. PT lesions were graded according to the AAST classification. RESULTS: Of a total of 46 PT, 34 were grades II or I. Hemodynamic instability led to immediate laparotomy in 18 patients, for whom treatment was always drainage of the pancreatic bed; morbidity was 30%. Eight patients had grade III injuries, six of whom underwent immediate operation: three underwent splenopancreatectomy without any major complications while the other three who had simple drainage required re-operation for peritonitis, with one death related to pancreatic complications. Four patients had grades IV or V PT: two pancreatoduodenectomies were performed, with no major complication, while one patient underwent duodenal reconstruction with pancreatic drainage, complicated by pancreatic and duodenal fistula requiring a hospital stay of two months. The post-trauma course was complicated for all patients with main pancreatic duct involvement. Our outcomes were similar to those found in the literature. CONCLUSION: In patients with distal PT and main pancreatic duct involvement, simple drainage is associated with high morbidity and mortality. For proximal PT, the therapeutic options of drainage versus pancreatoduodenectomy must be weighed; pancreatoduodenectomy may be unavoidable when the duodenum is injured as well. Two-stage (resection first, reconstruction later) could be an effective alternative in the emergency setting when there are other associated traumatic lesions.
