Retained bile duct stones.

Residual bile duct stones were found in 69 out of 4078 patients subjected to cholecystectomy. In 5 of these patients the outcome of the residual stones was unknown, but in 64 patients the complete course of events could be followed. In 32 patients the stone(s) were lodged in the intrahepatic ducts; in 15 patients the stones were overlooked owing to incomplete or technically unfeasible post-explorative cholangiographies; in 12 patients the stones were not visualized in good peroperative cholangiograms and in 5 patients the stones were misinterpreted as air bubbles. Spontaneous passage of the retained stones was verified in 24 patients. In 40 patients re-exploration was performed. Organic changes in the bile duct wall, a large (greater than or equal to 10 mm) and solitary stone were factors that precluded spontaneous passage. Re-exploration of residual bile duct stones, especially during the first month after the primary surgery, was found hazardous. If possible re-exploration should not be performed earlier than 4-6 weeks after the primary operation.

[Behavior of Ethephon residues on stone fruits and berries. 1. Ethephon residues on sweet and sour cherries].

The authors describe a gas chromatographic method for determing Ethephone residues. Studies on the residual behaviour of Ethephon on sweet cherries showed that the fruits contained 0.88, 1.45 and 1.83 p.p.m. of Ethephon after applications of 0.05, 0.075 and 0.1% Flordimex mixture, respectively. When the same doses were applied to sour cherries, the fruits contained 0.54, 1.12 and 1.44 p.p.m. of Ethephon; and the juices, 0.81, 1.36 and 1.77 p.p.m.

The residual renal stone.

A study of the observer error built in to contact preoperative radiography for renal stones shows that particles less than 2 mm in diameter are likely to be missed. The radiographic follow-up of 100 patients from whom 120 large staghorn calculi have been removed over a period of up to 10 years shows that new calculi may form in kidneys which have been completely cleared, and that residual stones do not always grow, but equally often pass spontaneously, or remain unchanged.

The selective use of combined supraduodenal and transduodenal exploration of the common bile duct.

The results of combined supraduodenal and transduodenal exploration of the common bile duct in 42 selected cases are presented. The indications for this operation were: the presence of multiple calculi in the common bile duct; stones impacted in the ampullary region; residual stones in the common bile duct following previous surgery on the biliary tract; stricture at the papilla and pancreatitis associated with cholelithiasis. After the procedure no patient had residual stones in the common bile duct. Serious complications were infrequent; there were no postoperative deaths and post-operative pancreatitis occurred in only one patient.

Principles in operative treatment of residual bile duct stones.

Of sixty-five patients with residual bile duct stones 17 patients had a supraduodental choledochotomy as the only operative procedure. Of the remainder, 48 patients, a supplementary sphincteroplasty was carried out in 36, and a choledochoduodenostomy was added in 12 patients. Early postoperative results showed two deaths, while 40 patients passed an uneventful postoperative course. Following sphincteroplasty three patients had residual stones at the postoperative cholangiography. These calculi had disappeared at follow-up examination. Follow-up examination with a mean observation period of six years revealed 50 patients free of symptoms. Four patients were re-operated on because of residual stones. None of these had a sphincteroplasty. It is concluded that in the operative treatment of residual bile duct stones sphincteroplasty and choledochoduodenostomy offer valuable supplements to the supraduodenal choledochotomy.

Non-operative treatment of retained bile duct calculi in patients with an indwelling T tube.

The results of combined instrumental and chemical treatment of retained bile duct calculi in 18 patients with an indwelling T tube are reported. The instrumental extraction of stones was carried out through the T tube channel using a modified Dormia apparatus. The chemical method involved continuous infusion through the T tube of heparin in saline alternating with sodium cholate. The treatment was successful in 16 of 18 patients with from 1 to 14 residual stones. The instrumental extraction of stones is recommended as the treatment of choice 5--6 weeks after choledochotomy in patients with residual stones and an indwelling T tube. Subsequent chemical treatment is recommended if remnants of stones are left in the bile duct after instrumental treatment.

Role of External Vibratory Lithoclast (Lithecbole) in Improving Lower Pole Stone Clearance After Extracorporeal Shock Wave Lithotripsy (ESWL).

<b>Background and Objective:</b> Extracorporeal shock wave lithotripsy (ESWL) is a widely used non-invasive treatment for renal stones. However, its effectiveness in clearing stones located in the lower pole of the kidney is often limited due to the anatomical challenges that impede the spontaneous passage of fragmented stones. This study evaluate the efficacy and safety of External Physical Vibration Lithecbole (EPVL) when used as an adjunctive therapy following ESWL in patients with lower pole renal stones, with a focus on improving stone clearance rates. <b>Materials and Methods:</b> This prospective interventional study was conducted at Al Yarmouk Teaching Hospital over two years and included 100 patients with 10-15 mm lower pole renal stones. Patients were randomized into two groups: The ESWL alone and ESWL plus EPVL. All patients received two ESWL sessions (3000 shocks/session). The treatment group additionally received EPVL therapy using a flank-applied vibration device. Follow-up was performed using ultrasound and KUB radiography. Statistical analysis was conducted using appropriate tests with significance set at p<0.05. <b>Results:</b> Baseline characteristics, including age, gender, weight, stone size and location, were statistically comparable between groups. The mean stone size was 12.4&#xb1;1.7 mm. A significantly higher stone-free rate was observed in the ESWL+EPVL group compared to the ESWL-only group (66% vs. 48%, p = 0.027). Although the residual stone size showed a numerical difference favoring EPVL, it was not statistically significant (p = 0.11). Complication rates were low, mild and similar in both groups (p = 0.3). Logistic regression analysis revealed that smaller stone size (p<0.001) and lower patient weight (p = 0.030) were significantly associated with successful stone clearance. Subgroup analysis further confirmed that patients with stones <11 mm or a weight <70 kg had the highest stone-free rates. <b>Conclusion:</b> In this initial evaluation, EPVL demonstrated a safe and effective adjunct to ESWL in enhancing stone clearance for lower-pole renal stones. Its application was associated with improved treatment outcomes without increasing complication rates. Further studies with extended EPVL sessions and longer follow-up are warranted.

Operative cholangiography and overlooked stones.

In a series of 100 consecutive common bile duct explorations in which stones were present and operative cholangiography performed, 22 patients were found to have residual stones. The operative cholangiograms showed the missed stones in three fourths of the patients, even though many of the cholangiograms were of poor quality. It is concluded that operative cholangiography is an excellent technique that will demonstrate most common bile duct stones. Closer cooperation with the radiologist and more emphasis on technique should lead to consistently satisfactory films and more appropriate interpretation, thus resulting in fewer overlooked biliary calculi.

[Cholelithiasis--indications for cholecystectomy, papillotomy and gallstone dissolution (author's transl)].

Patients under 50 years without risk factors carrying gallstones should be operated upon for the following reasons: (1) These patients will have complications in up to 40% of cases with increasing age; (2) only 18% of patients are without complaints after a duration of this disease of twenty years; (3) mortality of surgery is 1,06% in patients with no other risk factors. Patients at risk for other reasons, with a functional gallbladder and carrying calcium-free stones should be treated with chenodesoxycholic acid. Patients at risk for other reasons carrying residual stones after cholecystectomy, or suffering from stenosis of the papilla, or harboring stones in the choledochus after choledochoduodenostomy should be subjected to endoscopic papillotomy. Patients at risk for other reasons suffering from cholecystolithiasis or choledocholithiasis should be subjected at first to endoscopic papillotomy, and only thereafter to cholecystectomy. This will decrease the risk of surgery.

[To day's biliary surgery (author's transl)].

Cholelithiasis is on the increase and operative indications are of a wider range including even preventive procedures. Surgery for silent stones, intra-operative cholangiography, indications for papillosphincterotomy and anastomoses, as well new procedures for nonoperative removal of residual stones are discussed. Transhepatic drainage for some reiterative stenoses of high anastomoses is recommended.

[Drainage in biliopancreatic surgery].

Among the various drains used in biliary tract surgery the T-tube drain proves to be most useful as a routine drainage procedure after any intervention for common duct stones. This drain allows an undisturbed healing of the common duct incision, an intra- and postoperative control cholangiography and, if necessary, a non-operative extraction of a residual stone. For high strictures of the hepatic duct we recommend the straight transhepatic drain and for palliative procedures in cases of centrally located tumors the Y-T-drain may restore bile flow from both the left and the right liver into the duodenum. If a drain in the pancreatic duct is necessary at all, one best uses a straight catheter that is brought out through the jejunum by means of a Witzel canal. The abdominal cavity is being drained routinely also for simple biliopancreatic surgery with a Penrose drain.

Urease stones.

Urinary stones form as a consequence of urinary supersaturation. Supersaturation occurs as a result of elevated concentrations of urinary solutes. Dietary, metabolic, endocrine, hereditary, and infectious processes alter urinary solute concentrations. Struvite (MgNH4PO. 6H2O) and carbonate-apatite [Ca10(PO4)6CO3] stones form in urine that becomes supersaturated as a by-product of the hydrolysis of urea by the bacterial enzyme urease. Urease-induced stones manifest primarily as branched renal calculi and as bladder calculi. Conventional therapy has usually consisted of surgical removal of the stone combined with a short course of antimicrobial therapy. Such treatment is curative in about 50% of cases. Recurrent stone formation and progressive pyelonephritis occur in those who are not cured. Adjunctive medical treatment with acetohydroxamic acid or hydroxyurea lessens the risk of calculogenesis and decreases growth of residual stones in patients who are not cured by conventional therapy. Patients with urea-splitting urinary infection and renal stones have a major life-threatening disease. The morbidity and expense that result from this disease are great. Long-term (perhaps lifetime) chemotherapy with antimicrobial agents and/or urease-inhibiting drugs combined with judicious and expert surgical intervention can be expected to significantly improve the plight of these unfortunate patients.

Endoscopic fistulotomy (EFT) for parapapillary choledochoduodenal fistula.

Up to now, surgery was the only possible treatment for choledochoduodenal fistulas, which are seen more often in Japan than in Europe. This paper presents the value and effect of endoscopic fistulotomy (EFT) as an alternative treatment in those cases. Parapapillary choledochoduodenal fistulas are abserved usually on the longitudinal fold of the papilla or on its oral side. The papillotome is inserted into the common bile duct through the orifice of the duodenal papilla, then the wall between its orifice and the fistula is cut to open widely the distal portion of the choledochus. EFT was performed successfully in 7 cases. The procedure led to a wide open stoma of the distal common bile duct with free bile outflow. Residual stones, a common occurrence in cases of parapapillary choledochoduodenal fistulas, may pass spontaneously after EFT or can be removed with a basket catheter. In cases of parapapillary choledochoduodenal fistula, EFT is a reliable method, especially in high-risk patients, and an alternative to surgical treatment.

Massive postoperative hemorrhage from hepatic artery erosion.

A 66-year-old male patient who had undergone repeated operations for peptic ulcer disease involving the right upper abdominal quadrant, developed cholecystitis with calculous obstruction of the common bile duct. The gallbladder was removed. Later, an operation was performed for removal of a residual stone from the common duct. At this time an anomalous arterial structure was noted about the duct. Hemorrhage occurred ten days postoperatively, and the anomalous hepatic artery was found to be eroded. The bleeding was controlled. During the succeeding two weeks there were four episodes of bleeding (involving erosion of the hepatic artery and adjacent tissues), three of which were controlled. The fourth episode ended in the death of the patient from exsanguination secondary to bleeding from stress ulcers in the gastric remnant. At no time did the laboratory data unequivocally indicate an abnormality of blood coagulation. Erosion of the anomalous cystic artery apparently precipitated the fatal chain of events.
