ABSTRACT

BACKGROUND: The mesopancreatic resection margin after pancreaticoduodenectomy for carcinoma of the head of the pancreas is of great interest with respect to curative resection, since the neoplastic involvement of this margin was shown to be the primary site for R1 resection. In this review the current knowledges of the surgical anatomy of the so-called mesopancreas and the mesopancreas excision techniques are summarized. METHODS: References were identified by searching Pubmed database using the search terms "mesopancreas" and "meso-pancreatoduodenum" until June 2013 and through searches of the authors' own files. Five studies were included in this review. RESULTS: Original contributions with regard to the anatomy of the retropancreatic area and specific technical descriptions of so-called "total mesopancreas excision" provided by published studies are pointed out. CONCLUSIONS: Because there is no "meso" of the pancreas, and due to the continuity of the mesopancreatic and para-aortic areas, surgical dissection should be extended to the left of the superior mesenteric artery and include the para-aortic area to achieve the most complete possible resection of the so-called mesopancreas and minimize the rate of R1 resections due to mesopancreatic margin involvement. This extended mesopancreatic resection cannot be accomplished en bloc even if the removal of the dissected mesopancreatic tissues is performed en bloc with the head, uncus, and neck of the pancreas, i.e., with the pancreaticoduodenectomy specimen.

ABSTRACT

AIMS: Two cases of chronic abdominal hypertension in pseudo-Meigs' syndrome, one sustained by a large ovarian bilateral carcinoma and the other by a giant genital angiomyolipoma, are reported. METHODS AND RESULTS: Both patients presented to the emergency room for abdominal distention and pain with progressive respiratory dysfunction, hypotension over several days, and early symptoms of renal failure, together suggestive of chronic, intra-abdominal hypertension. DISCUSSION: Intra-abdominal hypertension and abdominal compartment syndrome are serious conditions which may complicate large tumors and tense ascites, apart from their benign or malignant nature. The chronic development of abdominal hypertension and onset of the abdominal compartment syndrome associated with Meigs' syndrome must be recognized in a timely manner and promptly treated by performing as complete a resection of the pelvic mass as possible; alternatively, in acute abdominal hypertension the monitoring of bladder pressure can evaluate the effectiveness of medical therapy and determine the optimal timing of decompressive laparotomy in case of the abdominal compartment syndrome.

ABSTRACT

The present study aims to investigate the feasibility and influence of the lymphatic mapping and sentinel node biopsy on determination of the nodal status in thyroid carcinoma using blue-dye method. Nine consecutive patients with cytological diagnosis of papillary carcinoma were included in this study. To detect the sentinel lymphnode, intra- or perinodular injection of an average quantity of 0.5 ml (range : 0.1-1.2) of Ble Patenté V was performed intraoperatively in 8 cases only, as in one case a solitary cystic nodule occupied the entire lobe and thus any injection was impossible. After an average time of 16 minutes (range : 5-25) before dissection of the thyroid , no lymphnodes and no lymphatic afferent thereto visibly coloured were evidenced, except for spread of the vital dye into adjacent tissue and disrupted blood and lymphatic vessels at the injection site. Our results evidence that : intranodular injection, does not allow proper diffusion of the dye in the adjacent parenchyma, and in nodules smaller than 1 cm it may be difficult ; and that it is hazardous in cystic nodule because of the rupture risk; perinodular injection, at the four cardinal points, is impossible when the nodule occupies the entire lobe or the isthmus; multinodular goiter complicates the identification by palpation of the neoplastic nodule in which the dye should be injected or, if perinodular injection is given, to detect the parenchyma surrounding the nodule.

ABSTRACT

BACKGROUND: In an attempt to improve the results of locally advanced rectal cancer treatment, we performed an extended surgical technique consisting of total mesorectal excision (TME), lateral pelvic lymphadenectomy (LPL) and total nerve sparing (NS). Resection of the autonomic nerves was realized only when these fibres were involved by the tumour. METHODS: Nine cases (9.2%) of a personal series of 98 western patients with rectal carcinoma operated on between January 1992 and December 1997 at Third Department of Surgery, University La Sapienza, Rome, underwent TME, LPL and NS procedures for locally advanced extraperitoneal disease. RESULTS: Two out of seven patients in stage II/III suffered postoperatively from urinary retention with mild irregular flow as tested on urodynamics, but no long-term urinary disturbances persisted. Retrograde ejaculation occurred postoperatively in one of two patients who experienced urinary disturbances. Another patient had erection dysfunctions. These sexual dysfunctions did not improve during the long-term follow-up. Seven patients with stage II or stage III disease achieved a 5-year survival rate of 80.0% and a 5-year disease-free survival rate of 68.6% after a mean follow-up period of 64.7 months. None of them experienced local recurrence, but one patient died of diffuse metastatic disease 50 months after surgery. Two patients with stage IV rectal carcinoma died of local and distant disease 13 months and 35 months after operation. One patient underwent liver resection for solitary metastasis 25 months after primary operation. CONCLUSIONS: TME, LPL, and NS with resection of autonomic nerves only when these fibres are involved by the disease can achieve satisfactory results in terms of survival and functional outcome in selected western patients with locally advanced rectal cancer.

ABSTRACT

In a pilot study undertaken in collaboration with the Department of Surgery of "San Carlo di Nancy" Hospital in Rome, over the period form January 1998 to February 2000, 128 patients with haemorrhoidal disease underwent surgery using a circular stapler to "lift" the mucous-haemorrhoidal prolapse, according to the pathogenetic theory discussed here below. We compared the results of our series with those of a retrospective series of 80 patients that undergoing traditional surgery (Khubchandani 45, Milligan-Morgan 30, Whitehead 5), evaluating length of operation, postoperative pain and complications. Our preliminary data show that the technique requires only a short learning period, reduces the length of the operation, reduces the medium- and long-term pain and allows mables the patient to resume full working activity earlier.

ABSTRACT

The aim of radical surgical treatment of rectal cancer is to control the spread and prevent recurrence of the disease. In an attempt to improve the results of treatment of locally advanced rectal cancer, we advocate an extended surgical approach consisting of total mesorectal excision, lateral pelvic lymphadenectomy and the nerve sparing technique with resection of autonomic nerves whenever these fibers are affected by locally advanced tumor. Nine cases (9.2%) in a personal series of 98 patients with rectal carcinoma, operated on over the period from January 1992 to December 1997, underwent total mesorectal excision, lateral pelvic lymphadenectomy and the nerve sparing technique procedures for locally advanced extraperitoneal disease. In 7 patients with stage II or III disease, the 5-year survival rate was 80% and the 5-year disease-free survival rate 66.7% after a mean follow-up of 55 months. None of them experienced local recurrence, but one patient died of diffuse metastatic disease 50 months after surgery. One patient with stage IV rectal cancer died of disease 13 months postoperatively, while another patient with the same stage of disease is still alive with disease 26 months after surgery. One patient underwent liver resection for a solitary metastasis 25 months after the primary operation. Two patients suffered postoperatively from urinary retention with mild irregular flow at urodynamic testing, but no long-term urinary disturbances persisted. Retrograde ejaculation occurred postoperatively in one of the two patients who experienced urinary disorders, and another patient had erection disturbances. These sexual dysfunctions did not improve during long-term follow-up. Total mesorectal excision, lateral pelvic lymphadenectomy, and the nerve sparing technique, with resection of the autonomic nerves whenever these fibers are involved, allow satisfactory results to be achieved in terms of survival and functional outcome in patients with locally advanced rectal cancer. In western subjects, however, this procedure is safe only after careful patient selection.
