Reoperation Due to Complications after Gastric Restriction Operation

Background: In the past 4 years we performed operations on 90 patients who suffered from morbid obesity. Five different operative techniques were available, vertical banded gastroplasty (VBG), silastic ring vertical gastroplasty (SRVG), gastric banding operation, adjustable silicone gastric banding (ASGB) and biliopancreatic diversion (BPD). Methods: Two of these operations were mainly utilized. The ASGB was done routinely. The SRVG was used particularly for patients with hiatal hernia. Only one patient, who had a deformed pylorus, underwent the BPD. Results: Eleven patients had to be reoperated due to complications after the first operation of gastric restriction. They were divided into three groups depending on the type of complication: reoperation due to lack of compliance, due to technical failure, or due to other complications. In the last group we observed three patients with band perforation into the stomach without epigastric pain. This complication has, to our knowledge, only been described in very few cases. Conclusion: In some patients it remained difficult to reach adequate compliance, although we kept close contact with them after the operation. We do not yet know the reasons for the band perforation observed in three patients.     

慢性病毒性肝炎胆囊声像异常与肝组织炎症坏死程度的关系

目的：探讨慢性病毒性肝炎胆囊声像异常与肝组织炎症程度的关系。方法：分析了１１２例慢性肝炎患胆囊壁厚度,光滑度,胆囊大小异常,合并胆囊结石及息肉的发生率,并与肝组织病理炎症坏死程度分级进行比较及相关分析。结果：胆囊声像异常总发生率为５７．１４％,胆囊壁厚在轻、中、重度慢性肝炎相互间比较差异均有显性,与肝脏炎症坏死程度呈显性正相关（ｒ＝０．６７,Ｐ〈０．０００１）。胆囊壁不光滑及胆囊大小异常发生     

The effect of polycythemic hyperviscosity on ischemic bowel necrosis

It is known that polycythemia decreases the fluidity of the blood and impairs tissue perfusion due to red-cell sludging in the microcirculation. In this study, the effect of polycythemic hyperviscosity (PH) on bowel necrosis was evaluated in an experimental model of intestinal ischemia. Twenty-eight Wistar albino rats (90–170 g) were divided into two groups: group 1 was transfused to create hyperviscosity and then intestinal ischemia was produced (n = 16); in group 2 ischemia was produced without transfusion (n = 12). Intestinal ischemia was produced by clamping the superior mesenteric artery and the collateral arcades of the right colic artery for 30 min. Gross and histopathologic evaluations were performed by either immediate necropsy or relaparotomy 24 h later. Microscopic findings were graded from 0 to 3 according to the degree of ischemic changes. In group 1, 2 animals (12.5%) died before 24 h postoperatively; coagulation necrosis with grade 2 or 3 ischemic changes was observed in 10 animals (62.5%). In group 2 only a few hypertrophied Peyer's patches and capillary dilation were found, and all histopathologic changes were between grades 0 and 1. The difference between the histopathologic gradings of the two groups was significant (P < 0.001). It appears that in addition to reduced splanchnic blood flow, a secondary effect of PH is needed to induce ischemic coagulation necrosis. PH of the newborn must be considered a risk factor for necrotizing enterocolitis, so-called spontaneous intestinal perforations, and even intestinal atresia.Presented at the 1st European Congress of Pediatric Surgery, Graz/Austria, May 4–6, 1995     

Gastric perforation secondary to recurrent trichobezoar

胆囊癌P~（53）、C－mycmRNA异常表达与TNM分期相关研究

应用地高辛标记的Ｐ￣(５３)、ｃ－ｍｙｃｃＤＮＡ探针对２１例胆囊癌石腊切片上的ｍＲＮＡ进行原泣杂交。结果表明ｃ－ｍｙｃ和Ｐ￣(５３)ｍＲＮＡ的表达均位于细胞核内。ｃ－ｍｙｃ和Ｐ￣(５３)ｍＲＮＡ在胆囊癌的表达率分别为６６．６％和５７．１％,在癌周正常组织中没有ｃ－ｍｙｃ、Ｐ￣(５３)ｍＲＮＡ的表达。ｃ－ｍｙｃ、Ｐ￣(５３)ｍＲＮＡ表达的强度和胆囊癌的原发肿瘤大小,有无淋巴结转移及远处转移有关。分期越晚,表达率越高。有淋巴结转移者高于无转移者。Ｐ￣(５３)ｍＲＮＡ表达的阳性率和胆囊癌的分化程度无关;而ｃ－ｍｙｃｍＲＮＡ的表达和分化程度有关,分化越差,表达率越高。     

Generalized amyloidosis from β2-microglobulin,with caecal perforation after long-term haemodialysis

Summary A 73-year-old man with chronic renal failure of undetermined aetiology had received haemodialysis for 12 years when he died of acute purulent peritonitis due to caecal perforation. Amyloid deposits detected in a cystic bone lesion in the left hip had caused a pathological fracture 17 days before death. At autopsy, extensive amyloid deposits were found in the osteoarticular system, in the cartilaginous surface and the capsular tissue of joints, ligaments, vertebral discs and bone. In addition, vascular amyloid deposits were diagnosed in the heart, kidneys, testes, lungs, skin and in the gastrointestinal tract. A special feature of this case were interstitial amyloid deposits forming a fine-meshed structure in the myocardium and plate-like deposits in the gastrointestinal tract. Immunohistochemically, all these deposits reacted strongly with antibody to human ₂-microglobulin but showed no reaction with antibodies to AA, Alambda, A-kappa and AF. The present case demonstrates that extra-osteoarticular manifestations of AB-amyloidosis can cause serious complications.     

Computed tomography as an adjunct to ultrasound in the diagnosis of acute acalculous cholecystitis

The sonographic and computed tomographic (CT) findings were reviewed in 17 patients with acute acalculous cholecystitis (AAC) over a 6-year period from 1984 to 1989. Of the six patients in whom both ultrasound and CT were performed, CT revealed marked gallbladder (GB) wall abnormalities, including perforation, and pericholecystic fluid collections in five patients not demonstrated by sonography. Of the total group, five patients had GB wall thicknesses of 3 mm (normal) at pathologic examination, which demonstrated a spectrum of disease ranging from acute hemorrhagic/necrotizing, to gangrenous acalculous cholecystitis with perforation. Sonography was falsely negative or significantly underestimated the severity of AAC in seven of the 13 patients examined by sonography. CT because of its superior ability to assess pericholecystic inflammation may provide additional diagnostic information even after a thorough sonographic study in cases of AAC.
