Laparoscopic 3D high-definition Deloyers procedure: when, how, why?
No full textAfter extensive mobilization and resection of the left colon, colorectal anastomosis may result impossible due to the distance between the remaining colon and the rectal stump. The Deloyers procedure represents an interesting alternative to total colectomy with ileorectal anastomosis. In this manuscript, we describe when and how to perform this technique with a mini-invasive approach. We also report the case of a patient who underwent Deloyers procedure, due to early ischemia of the descending colon after left colectomy
Laparoscopic splenectomy: Experience of a single center in a series of 300 cases
No full textBACKGROUND:
Laparoscopic splenectomy (LS) has gradually become the technique of choice for surgical removal of the spleen. The aim of this study was to evaluate the efficacy of LS in a large cohort of patients from a single center.
METHODS:
From March 1992 to June 2010, 300 patients underwent LS at our hospital for predominantly hematologic disorders. The first 92 cases were performed using an anterior approach, whereas in the remaining 208 cases a lateral approach with a four-trocar technique was used. Patient demographics, diagnosis, and outcomes were reviewed.
RESULTS:
Spleen volume was similar between the anterior (350 ml) and the lateral (370 ml) approaches. The lateral approach was associated with shorter operative time (60 vs. 80 min), less blood loss (30 vs. 110 ml), and no conversion (0 vs. 2.2 %) compared to the anterior approach. Reoperations were required in three patients (1.0 %) because of bleeding, subphrenic abscess, and intestinal ischemia. Postoperative complications were significantly fewer for the lateral (4.8 %) than for the anterior (31.5 %) approach and the hospital stay was shorter (3.1 vs. 5.2 days) and there was less postoperative pain. Splenectomy for hematologic malignancies resulted in a higher morbidity rate, more postoperative pain, and longer hospital stay. Overall mortality rate was 0.3 %. No late complications were observed during the 1-5-year follow-up.
CONCLUSIONS:
LS using the lateral approach with the placement of four trocars can be considered the procedure of choice for both benign and malignant diseases affecting the spleen. Extensive experience and technical standardization help to avoid surgical pitfalls, providing an adequate control of hemostasis, the excision of accessory spleens (AS), and the avoidance of parenchymal rupture
Laparoscopic treatment of unicentric Castleman's disease with abdominal localization
No full textWe report a case of unicentric Castleman's disease (angiofollicular lymph node hyperplasia) with abdominal localization, that was treated laparoscopically. The patient, a 23-year-old male, was referred to our unit for subtle symptoms of recurrent palpitations and vague abdominal pain. His physician had prescribed an abdominal echtomograph, which showed a mass located at the lower and anterior lower splenic pole. In order to reach a definite diagnosis and prescribe adequate treatment, a diagnostic laparoscopy was performed. Exploration of the abdominal cavity helped detect a well-vascularized solid round mass at the level of the left hypochondrium, with a vascular pedicle; the lesion was detached, and the pedicle sectioned using an Endo-GIA 40. The postoperative course was regular and the patient was discharged on postoperative day 2. The laparoscopic approach enabled the resection of the lesion (with consequent histological diagnosis) and exploration of the peritoneal cavity with the advantages of minimal invasiveness, magnified images, and more rapid recovery). The pathology was totally resolved, with satisfactory results in terms of recovery, postoperative pain, and cosmesis

No full textLaparoscopic approach to gastric remnant-stump: Our initial successful experience on 3 cases
No full textINTRODUCTION:
Laparoscopic treatment of gastric adenocarcinoma is still a debated issue. In this paper, we retrospectively reviewed 3 cases of laparoscopic treatment of gastric remnant-stump adenocarcinoma. We analyzed the feasibility, the postoperative outcome, and the short-term results.
MATERIALS AND METHODS:
From January 2003 to September 2005, we carried out 3 laparoscopic completion gastrectomies for cancer of the remnant stomach. All patients were males, between 59 and 73 years old. All of them had a previous history of benign gastric ulcer that required a Billroth II subtotal gastrectomy. We always performed a D2 lymphadenectomy and a Roux an Y side-to-side esophagojejunostomy.
RESULTS:
No conversion was necessary. Mean operative time was 210 minutes (range: 160 to 260 min). No intraoperative transfusions were applied. We had 1 postoperative bleeding managed conservatively with 2 units of blood transfusion. In 1 case, the esophageal transit study showed a tiny anastomotic leak, not clinically evident, which was managed conservatively. The mean peristalsis was present at 56 hours (range: 48 to 72 h). The mean postoperative stay was 11 days (range: 8 to 18 d). In all cases, histologic examination was positive for adenocarcinoma. The mean number of lymph nodes was 18 (range: 12 to 26). The TNM status was: T2N0M0, T3N0M0, and T3N1M0. Resection margins were negative in all cases (R0). The mean follow-up was 17.6 months (range: 11 to 24 mo). The patient with positive lymph node died 11 months after the operation for metastatic disease.
CONCLUSIONS:
In our preliminary experience, laparoscopic treatment of gastric remnant-stump adenocarcinoma has been demonstrated to be technically feasible and sure. The histologic examination confirmed a proper surgical dissection. Also, if it is an initial experience, we believe that laparoscopy could be considered a valid opportunity to open surgery
Worldwide burden of colorectal cancer: a review
No full textColorectal cancer is a major public health problem, being the third most commonly diagnosed cancer and the fourth cause of cancer death worldwide. There is wide variation over time among the different geographic areas due to variable exposure to risk factors, introduction and uptake of screening as well as access to appropriate treatment services. Indeed, a large proportion of the disparities may be attributed to socioeconomic status. Although colorectal cancer continues to be a disease of the developed world, incidence rates have been rising in developing countries. Moreover, the global burden is expected to further increase due to the growth and aging of the population and because of the adoption of westernized behaviors and lifestyle. Colorectal cancer screening has been proven to greatly reduce mortality rates that have declined in many longstanding as well as newly economically developed countries. Statistics on colorectal cancer occurrence are essential to develop targeted strategies that could alleviate the burden of the disease. The aim of this paper is to provide a review of incidence, mortality and survival rates for colorectal cancer as well as their geographic variations and temporal trends
Laparoscopic total gastrectomy in gastric cancer: Our experience in 92 cases
No full textINTRODUCTION:
Laparoscopic total gastrectomy (LTG) is seldom used for gastric cancer because the complex vascularization and lymphatic drainage makes lymphadenectomy and esophagojejunal anastomosis difficult and requires special skills. Our aim was to demonstrate the feasibility and accuracy of LTG in gastric cancer with D2 lymphadenectomy.
MATERIAL AND METHODS:
Eighty-eight LTG and four laparoscopic remnant gastrectomies (LRGs) were performed over >12 years. The median patient age was 64 years, and the male/female ratio was 1.49/1. Eighty-seven patients had a D2 and only five patients had a D1 lymphadenectomy. We propose the retrospective analysis of intra- and perioperative mortality and morbidity.
RESULTS:
In only four of 96 cases approached by laparoscopy, a conversion to laparotomy was needed. There were two (2.17%) perioperative deaths in 92 procedures and few complications. Histological data show 79 advanced gastric cancers (AGC), 11 early gastric cancers (EGC), and two gastric diffused lymphomas. The five-year Kaplan-Meier overall survival in patients with EGC and AGC was 100% and 58%, respectively.
CONCLUSIONS:
The results demonstrate the feasibility of an oncologically correct minimally invasive total gastrectomy. We would like to promote comparisons among different institutions to achieve better standardization of indications and techniques for a laparoscopic approach to gastric cancer
Laparoscopic pancreaticoduodenectomy: Experience of 22 cases
No full textAbstract
BACKGROUND:
Laparoscopic pancreatic surgery has gradually expanded its applications to include pancreaticoduodenectomy. However, the benefits of the laparoscopic approach are still debated. This article aims to present data regarding the efficacy of laparoscopic pancreaticoduodenectomy in a single center.
METHODS:
From March 2003 to June 2010, a total of 22 patients underwent pancreaticoduodenectomy with a totally laparoscopic approach, using a five-trocar technique. Reconstruction of the digestive tract was adapted to the aspect of the pancreatic stump, with 6 patients having Wirsung duct occlusion and 16 patients pancreaticodigestive anastomosis. Patient selection, short-term outcomes, oncologic results, and technical issues were retrospectively reviewed.
RESULTS:
Mean operative time was 392 (range, 327-570) min. Conversion was required in 2 patients (9.1 %) as a result of bleeding and difficult dissection. Major intraoperative complications included an injury to the right hepatic artery (4.5 %). Postoperative mortality was 4.5 %. Surgery-related morbidity occurred in 14 patients (63.6 %) and included bleeding (n = 5), pancreatic fistula (n = 6), biliary fistula (n = 2), and dumping syndrome (n = 1). Pancreatic fistulas occurred in 4 patients with duct occlusion and in 2 patients with pancreaticojejunostomy, and they all healed with conservative treatment. Mean hospital stay was 23 (range, 12-35) days. Pathologic diagnoses were pancreatic ductal adenocarcinoma (n = 11), ampullary adenocarcinoma (n = 8), and duodenal adenocarcinoma (n = 3). The resection margins were all free from disease; the mean number of collected lymph nodes was 15 (range, 14-20).
CONCLUSIONS:
The complexity of pancreaticoduodenectomy entails some issues, including patient selection and management of the pancreatic stump, that are not related to the approach used. Laparoscopic pancreaticoduodenectomy is feasible, safe, and oncologically adequate, but only if performed in selected cases by highly skilled laparoscopic surgeons. Laparoscopy does not provide any significant advantage over traditional surgery, but it may improve postoperative outcomes in the so-called excellence centers, once the learning curve has been overcome. Multicenter randomized trials are needed
Relaparoscopy for management of postoperative complications following colorectal surgery: ten years experience in a single center
No full textLaparoscopy has increasingly become the standard of care for patients who undergo colorectal surgery for both benign and malignant disease. On the basis of this growing experience, there is now an expanded role for laparoscopic approach to postoperative complications after primary colorectal resection. However, there is little literature specific to this topic. We report a ten-year experience with laparoscopic treatment of early complications following laparoscopic colorectal surgery
Laparoscopic pancreas-preserving subtotal duodenectomy for gastrointestinal stromal tumor
No full textGastrointestinal stromal tumors (GISTs) of the duodenum are rare neoplasms. The optimal surgical procedure is debated and several options ranging from limited resections to pancreaticoduodenectomy have been reported. The laparoscopic approach has been validated for gastric GISTs, but it does not yet represent a standard technique for tumors of the duodenum. We report the case of a localized duodenal GIST that was successfully treated by totally laparoscopic pancreas-preserving subtotal duodenectomy. This procedure may represent a feasible and effective treatment option for localized GISTs of the duodenum. Large series with long-term follow-up are needed
