Laparoscopic total mesorectal excision for rectal cancer: experience of a single center with a series of 174 patients.

BACKGROUND: Laparoscopic total mesorectal excision for low rectal cancer is not considered a gold standard treatment due to the high conversion rate and the long operation time. METHODS: A retrospective review examined a surgical series of 174 laparoscopic low rectal resections involving total mesorectal excision (1995-2006), with particular reference to technical points as well as surgical and oncologic outcomes. Miles operations and partial mesorectal excisions were excluded. RESULTS: The cancer affected the low rectum in 110 cases and the medium rectum in 64 cases. A total of 68 patients were subjected to neoadjuvant radiochemotherapy. The anastomosis was mechanical for 83.3% of the cases and intersphinteric through the perineum for 16.6% of the cases. Protective ileostomy was performed in 112 cases. The conversion rate was 4.6%. The mesorectum remained intact in 91.6% of the cases and was partially interrupted in 15 of the cases. In no case was it totally discontinued. The postoperative morbidity rate was 16.7%, and the mortality rate was 0.57%. The incidence of anastomotic fistulas was 14.4%. The percentage was higher for males (18.6 vs 8.3%) and correlated with the low distance of the tumor from the anal verge (18.2 vs 7.8%) and the absence of a protection ileostomy (20.9 vs 10.7%). After an average follow-up period of 48.6 months (range, 24-149 months), six patients (3.44%) experienced a pelvic recurrence. The 5-year overall survival rate was 75.4%, and the disease-free survival rate was 61.9%. CONCLUSION: Laparoscopic total mesorectal excision for low rectal cancer is safe and effective, allowing surgical and oncologic outcomes similar to those reported for open surgery.

Small bowel obstruction. Laparoscopic approach.

BACKGROUND: This is a retrospective review of our experience using a laparoscopic approach in the treatment of acute and chronic small bowel obstruction (SBO). MATERIALS AND METHODS: Of 136 patients hospitalized in our institutions for acute (94 cases: 69.1%) and chronic (42 cases: 30.8%) SBO, from January 1994 to March 1998, 63 (46.3%) were approached laparoscopically. The etiology was accurately diagnosed in 58 cases (92%), and it was possible to treat it laparoscopically in 82.5% (52 of 63 cases). In the remaining 11 cases (17.4%), a formal laparotomy was needed for bowel resection, due to an ischemic small bowel or for malignant disease. RESULTS: Overall, 82.5% of our cases were successfully treated laparoscopically. CONCLUSIONS: We conclude that, in experienced hands, laparoscopy is an excellent diagnostic and, in the majority of cases, a therapeutic surgical approach in selected patients with acute or chronic SBO.

[Emergency laparoscopic surgery: a hospital's experience]. / Chirurgia laparoscopica d'urgenza: un'esperienza ospedaliera.

BACKGROUND AND AIM: The wide diffusion and increasing use of laparoscopic surgery prompts the authors to broaden discussion to its validity and diagnostic-therapeutic use in emergency abdominal surgery. The aim was to evaluate the efficacy of laparoscopic surgery in the light of reports in the international literature and in relation to the situation in our hospital. METHODS: From April 1994 to May 1998, out of 1016 emergency abdominal operations performed at our hospital, 783 (77.5%) used a laparoscopic approach for diagnostic and therapeutic purposes: intestinal occlusion: 26 cases; gastrointestinal ulcer pathology: 15 cases; hepatobiliary pathology: 398 cases; "pelvic" pathology: 305 cases; colic pathology: 39 cases. These represent 24.4% of all laparoscopic procedures carried out during the same period. We preferred to use immediate laparotomic access in patients with the following characteristics: anamnesis of previous surgery for malignant pathologies; anamnesis of more than two major abdominal operations; massive intestinal distension; patients whose general conditions were a contraindication to a laparoscopic approach. RESULTS: The conversion rate was 6.2% (49 cases) with morbidity of 3.4% (25 cases) and a mortality rate of 0.2% (2 cases). A final diagnosis was made in 763 patients (97.4%) with the possibility of treating 719 of them (94.2%), again using a laparoscopic approach. CONCLUSIONS: It is right to regard the laparoscopic approach in emergency abdominal surgery as a feasible and safe model, offering a high potential for diagnosis and therapy if appropriately performed by an expert and well coordinated team. The increased experience of mini-invasive surgery and the improved range of instruments available make the laparoscopic approach a valid alternative to laparotomy, even in the event of emergency abdominal pathologies.

[The standardization of a technic for laparoscopic left hemicolectomy with radical lymphadenectomy]. / Standardizzazione della tecnica dell'emicolectomia sinistra laparoscopica con linfoadenectomia radicale.

A standardized technique of left laparoscopic hemicolectomy is explained based upon the experience of the authors through the study of 166 cases and other cases described in literature. In the above study all of the single steps and the material needed for this technique, which is one of the most complex in laparoscopic surgery, are explained.

Laparoscopic cholecystectomy. Analysis of results of first 322 cases.

From April 1994 to June 1995 322 laparoscopic cholecystectomies were performed in S. Camillo hospital Treviso, 294 in election and 28 in urgency. The technique and results of this experience are reported. No mortality was observed and morbility was 1.8%. Utility of gallstones in main biliary duct screening is discussed to select patients to subject to preoperative ERCP and the role of intraoperative cholangiography. Laparoscopic cholecystectomy is considered the choice option in cholelitiasis. In case of evidence of choledocholithiasis with anamnesis or preoperative tests, the tactics of choice in authors opinion is the sequential one, providing preoperative ERCP and laparoscopic cholecystectomy.

[Gastrointestinal hemorrhage from a duodenal diverticulum]. / Emorragia gastrointestinale da diverticolo duodenale.

Duodenal diverticuli are often asymptomatic and are occasionally found during the course of X-ray tests or autopsy. They are sometimes manifested in the form of symptoms related to a complication (hemorrhage, perforation, occlusion). The paper reports a case of gastrointestinal hemorrhage caused by a duodenal diverticulum which was then successfully operated. The Authors affirm that in these cases the resection of the portion of the duodenum with the diverticulum (provided the papilla is not affected) is preferable to direct hemostasis or duodenocephalopancreatectomy.

[A splenic autograft in omental pockets following splenectomy for trauma. The authors' personal experience of 10 cases]. / Autotrapianto splenico su tasche omentali dopo splenectomia per trauma. Esperienza personale su 10 casi.

Personal experience on 10 patients splenectomised for trauma and subjected to splenic autotransplantation on omental pockets is reported. After describing autotransplant candidate selection criteria and the surgical technique followed, the flattering results are reported. Particularly interesting was the fact that no local suppuration was encountered and the transplant took in all patients, as demonstrated by scans carried out with labelled red globules and radiocolloid.

[Hemorrhages of the lower digestive tract: the diagnostic and therapeutic approach]. / Emorragie del tratto digestivo inferiore: approccio diagnostico e terapeutico.

The authors describe their experience with colo-rectal haemorrhage. They stress the tendency towards spontaneous arrest of such haemorrhages (92.6% of cases) as the usefulness of emergency colonoscopy in diagnosing the cause and/or site of the haemorrhagic lesion (85.7% of positive results in the present series). Therapy may be conservative (endoscopic or in the course of angiography) or surgical. Surgery is indicated in cases failing to respond to conservative therapy and in cases of unarrestable haemorrhage and usually consists in segmental resection of the portion of the intestinal tract involved.

[Endometriosis on a cesarean cicatrix. Apropos of 3 cases]. / Endometriosi su cicatrice per cesareo. A proposito di tre casi.

Endometriosis on a caesarean scar is a well-known, though not frequent event. The lesion generally presents as a painful nodule of the abdominal wall during the menstrual cycle. Pain cyclicity is a useful sign for diagnosis. Treatment consists of removal. Three cases are reported.

[Non-traumatic colic perforation in free peritoneum. Apropos of 61 cases]. / Perforazioni coliche non traumatiche in peritoneo libero. A proposito di 61 casi.

Sixty-one non-traumatic perforations in free peritoneum are reported. The principal aetiology is diverticulitis (35 cases) followed by cancer (22 cases). 18 derivations were carried out, 34 colectomies without anastomosis, 5 ideal colectomies and 4 diverticulectomies. Total mortality was 19.7-14% for diverticulitis, 22.2% for perforations at the cancer site, 50% from diastasic perforations. Stress is laid on the need to treat colic perforation by colectomy without anastomosis, confining derivation openeum. Sixty-one cases.

[Intra-abdominal rupture of varices of the round ligament: a rare cause of hemoperitoneum in patients with cirrhosis]. / La rottura intra-addominale di varici del ligamento rotondo: rara causa d'emoperitoneo nel cirrotico.

The authors report two cases of haemoperitoneum due to intra-abdominal rupture of the round ligament in cirrhotic patients with portal hypertension. A review of the literature on the subject reveals the rarity of such observations. The eventuality must be borne in mind, however, in the treatment of the haemorrhagic complications of portal hypertension in view of the associated high mortality. Simple ligature of the bleeding varix is the operation which offers the greatest possibility of survival.

[Lesions caused by the ingestion of caustics]. / Lesioni da ingestione di caustici.

The diagnostic and therapeutic approach to the maiagement of lesions caused by ingestion of caustic substances has made substantial progress in the past few years and has now been codified. The linch-pins of the present approach are emergency endoscopy for an immediate assessment of the lesions and total parenteral nutrition to reduce the morbidity in patients whose lesions may be expected to take a long time to heal or may require surgical repair. The diagnostic and therapeutic protocol advocated derives from a close examination of the literature and from personal experience.

[Recent traumatic rupture of the diaphragm in patients with multiple injuries]. / Le rotture traumatiche recenti del diaframma nei politraumatizzati.

The authors report on 16 cases of recent traumatic diaphragmatic lesions in polytraumatized patients referred to them over the period 1979-86. After examining the diagnostic problems relating to this type of lesion, the authors describe the anatomico-topographical, clinical and therapeutic aspects. They conclude by stressing the need to explore the diaphragmatic cupulae systematically in the course of surgery for blunt abdominal trauma.
